2    This charge was previously referred to as the “OBRA Expense Charge”. Due to a 1990 federal tax law change under the Omnibus Budget
     Reconciliation Act of 1990 (“OBRA”), as amended, insurance companies are generally required to capitalize and amortize certain
     acquisition expenses rather than currently deduct such expenses. Due to this capitalization and amortization, the corporate income tax burden
     on insurance companies has been affected. To compensate us for corporate taxes, we make a charge of 1.25% of the premium for scheduled
     premiums due (or unscheduled premiums paid) prior to the Policy Anniversary in 2010 and 1.00% of subsequent premiums.
3    The premium surrender charge is a percentage of the surrender charge base, the amount of which will vary depending upon whether you
     suspended the payment of scheduled premiums at any time during the first five Policy Years. The premium surrender charge percentage
     varies by Issue Age and typically increases between Policy Years one through five, remains levels in Policy Years five through ten, and
     declines in Policy Years eleven through fifteen to zero. For more information on the calculation of the premium surrender charge, see
     “Surrender Charges” in this prospectus.
4    This fee may increase over time to cover our administrative or other costs but will not exceed the maximum charge. We may discontinue this
     service at any time, with or without notice.
5    The maximum charges are subject to a consumer price index adjustment. The maximum charge will equal the maximum charge shown above
     multiplied by the CPI for the fourth month prior to the time of the charge, divided by the CPI for April, 2009. “CPI” means the Consumer
     Price Index for All Urban Consumers, United States City Average, All Items, as published by the United States Bureau of Labor Statistics. If
     the method for determining the CPI is changed, or it is no longer published, it will be replaced by some other index found by the Company to
     serve the same purpose.

1    Some fees and expenses, such as fees applicable in Policy Years prior to your current Policy Year, may no longer apply because the Policy is
     no longer issued.
2    See “Deductions and Charges—Charges Against the Policy Value” for more information about how we determine cost of insurance rates.
     The amounts of these deductions may be effectively reduced by the dividends we may pay on in-force Policies. The dividends we currently
     pay are reflected in illustrations we provide. You may request an illustration from your Financial Representative. We do not guarantee future
     dividends. (See “Annual Dividends.”) The cost of insurance rate shown in the table may not be representative of the charge that a particular
     Owner may pay. Generally, higher Issue Ages and/or worse underwriting classifications will result in higher cost of insurance rates, and men
     will pay higher rates than women. The net amount at risk is the projected Death Benefit, discounted at a net annual rate of 4%, less the sum
     of the Policy Value and the Cash Value of any paid-up insurance. The projected Death Benefit is the Death Benefit at the end of the Policy
     Year, assuming a 4% net annual growth rate. Request an illustration for personalized information from your Financial Representative. (See
     “Illustrations.”)

4      Variable CompLife® Prospectus
3    The charges shown in the table may not be representative of the charge that a particular Owner may pay. The charges for Waiver of Premium
     Rider and Additional Purchase Benefit do not vary by sex. Generally, these charges increase for older Issue Ages except that the charge for
     Waiver of Premium rider does not increase after age 57. In addition, higher rates may apply to substandard underwriting classifications.
4    The maximum benefit amount is $100,000.
5    Varies by age and underwriting classification.
6    This charge is a loan interest spread; that is, the difference between the interest charged and the amount credited to the Policy. This amount is
     deducted from Invested Assets. (See “Policy Loans and Automatic Premium Loan—General Loan Terms.”)

Annual Portfolio Operating Expenses
The table below shows the range (minimum and maximum) of total operating expenses, including investment advisory fees,
distribution (12b-1) fees and other expenses of the Portfolios that are available for investment under the Policy. The first line of
this table lists expenses that do not reflect fee waivers or expense limits and reimbursements, nor do they reflect short-term
trading redemption fees, if any, charged by the Portfolios. The information is based on operations for the year ended
December 31, 2010. More details concerning these fees and expenses are contained in the attached prospectuses for the Funds.
                                                                                                                                                   Minimum   Maximum

*     For certain Portfolios, certain expenses were reimbursed or fees waived during 2010. It is anticipated that these voluntary expense reimbursement and fee
      waiver arrangements will continue past the current year, although certain arrangements may be terminated at any time. After taking into account these
      arrangements and any contractual fee waiver or expense reimbursement arrangements, Annual Portfolio Operating Expenses would have ranged from a
      minimum of 0.21% to a maximum of 1.50%.
**    The “Range of Total Annual Portfolio Operating Expenses After Contractual Fee Waiver or Reimbursement” line in the above table shows the minimum and
      maximum fees and expenses charged by all of the Portfolios after taking into account contractual fee waiver or reimbursement arrangements in place. Those
      contractual arrangements are designed to reduce Total Annual Portfolio Operating Expenses for Owners and will continue for at least one year from the date
      of this prospectus. For more information about which Portfolios currently have such contractual reimbursement or fee waiver arrangements in place, see the
      prospectuses of the underlying Funds.

The following table shows total annual operating expenses of each Portfolio available for investment under the Policy. Operating
expenses are expressed as a percentage of average net assets for the year ended December 31, 2010, except as otherwise set forth
in the notes to the table. The Russell Investment Funds LifePoints® Variable Target Portfolio Series are funds of funds and
because of their two-tiered structure, may have fees that are higher than other funds. The Portfolio expenses used to prepare the
table were provided to the Company by the Portfolios. The Company has not independently verified such information. The
expenses shown are based on expenses incurred for the year ended December 31, 2010, or restated to reflect current expenses (see
attached prospectuses for the Funds). Current or future expenses may be higher or lower than those shown, especially in periods
of market volatility.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital. Current income is a secondary objective.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                Example
    (fees paid directly from your investment)            N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other

                                                                    in the Portfolio for the time periods indicated and then redeem

    Other Expenses                                      0.02%       these assumptions your costs would be:

  The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 48.90% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio invests primarily in the equity securities of well established, medium and large capitalization companies. Stocks are
selected for their above average earnings growth potential, with an emphasis on companies that have strong financial
characteristics. For this purpose, medium capitalization companies are those with a market capitalization between the 25th and
75th percentile companies in the Russell MidCap® Index and larger capitalization companies are those with a market
capitalization above that range. As of December 31, 2010, the 25th and 75th percentile companies in the Russell MidCap® Index
had market capitalizations of $7.23 billion and $2.77 billion, respectively.
In keeping with its growth strategy, the Portfolio employs a “bottom up” analysis to seek to identify companies which have the
potential to grow faster than average given current and expected economic conditions and the outlook for the economic sector and
industry in which they compete. In evaluating individual companies, the adviser considers factors such as the company

                                                               NMSF–1                       Northwestern Mutual Series Fund, Inc.
Growth Stock Portfolio
management team, product outlook, competitive position, global exposure, financial characteristics and valuation. While most
assets will be invested in U.S. common stocks, other securities may also be purchased, including preferred stocks, warrants, and
securities convertible into common or preferred stocks, in keeping with the Portfolio’s objectives.
The Portfolio seeks to reduce overall risk by diversifying its assets in an appropriate manner. This diversification will span
economic sectors, industry groups and companies. The adviser may overweight or underweight the sector exposure of the
Portfolio relative to its benchmark based on the adviser’s assessment of the relative attractiveness of such sectors. In
implementing this top down analysis, the adviser may utilize options, futures, forwards, swap agreements and exchange-traded
funds as a cash management strategy, to seek to enhance returns or as alternatives to direct investments when the adviser deems it
to be more efficient or advantageous. The Portfolio may invest up to 20% of net assets in American Depositary Receipts and
other securities of foreign issuers.
The Portfolio may sell securities for a variety of reasons, such as to secure gains, when the adviser perceives a significant change
in the outlook for a company or industry, or to make room in the Portfolio for more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a growth
  style of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the
  Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid Cap Company Risk – Investing in mid cap stocks may cause greater risk of loss and price fluctuation than investing in
  stocks of larger cap companies due to a more limited track record, narrower product markets, more limited resources and less
  liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than stocks with larger
  capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                Example
    (fees paid directly from your investment)           N/A         This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
    Management Fee                                      0.77%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees               None
                                                                    Although your actual costs may be higher or lower, based on
    Other Expenses                                      0.02%       these assumptions your costs would be:
    Total Annual Portfolio Operating Expenses           0.79%            1 Year         3 Years         5 Years         10 Years
    Fee Waiver*                                        (0.02)%              $79           $250            $436            $975
    Total Annual Portfolio Operating Expenses After
    Fee Waiver*                                         0.77%

* The Portfolio’s investment adviser has entered into a written
agreement to waive a portion of its management fee, such
thatthe management fee is 0.75% on the Portfolio’s first $100
million of assets, 0.70% on the next $200 million and 0.65%
on the next $200 million. This fee waiver agreement maybe
terminated by the adviser at any time after April 30, 2012.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 40.65% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio invests primarily in the equity securities of companies selected for their growth potential. The Portfolio may invest
in companies of any size, from larger, well established companies to smaller, emerging growth companies. In seeking to
implement its growth strategy, the adviser employs a “bottom up” approach in choosing investments for the Portfolio. That is, the
adviser looks at companies one at a time to determine if a company is an attractive investment opportunity and is consistent with


Northwestern Mutual Series Fund, Inc.                          NMSF–4
                                                                         Focused Appreciation Portfolio
the Portfolio’s investment policies. In reviewing potential investment candidates, the adviser places extra emphasis on the
following key investment criteria: strong market share and pricing power, open-ended growth potential, strong cash flow and
clear strategy for investing, and significant appreciation potential relative to current price.
Although the Portfolio is diversified, the Portfolio may hold larger positions in a smaller number of companies than more
diversified funds and, in anticipation of such investments, may hold a correspondingly larger position in cash pending investment.
The Portfolio invests primarily in a core group of 20-40 common stocks.
The Portfolio also may invest in special situations. A special situation arises when, in the opinion of the adviser, the securities of
a particular issuer will be recognized and appreciate in value due to a specific development with respect to that issuer. Special
situations may include significant changes in a company’s allocation of its existing capital, a restructuring of assets, or a
redirection of free cash flow. Developments creating a special situation might include, among others, a new product or process, a
technological breakthrough, a management change or other extraordinary corporate event, or differences in market supply of and
demand for the security.
Within the parameters of its specific investment policies, the Portfolio may invest up to 20% of net assets in American Depositary
Receipts and securities of foreign issuers, which may include investments in emerging markets. The Portfolio may use derivatives
for different purposes, including hedging (to offset risks associated with an investment or market conditions), to earn income and
to seek to enhance returns.
Portfolio securities may be sold for a variety of reasons, including to secure gains, to limit losses, to make room in the Portfolio
for more promising opportunities or based on the Portfolio’s absolute and relative risk monitoring targets.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a growth
  style of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the
  Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Focus Risk – The Portfolio’s performance could be more closely tied to the value of a single security or small number of
  securities because, although diversified, the Portfolio may hold large positions in a single or small number of securities. As a
  result, the Portfolio’s performance could be more volatile than the performance of funds that hold a greater number of
  securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.

                                                              NMSF–5                        Northwestern Mutual Series Fund, Inc.
Focused Appreciation Portfolio
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid and Small Cap Company Risk – Investing in mid and small cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.
• Special Situation Risk – The risk that the change or event anticipated by the adviser when purchasing a company might not
  occur or attract the expected attention, which could have a negative impact on the price of the company’s securities. Investing
  in special situations may involve heightened volatility in the value of the securities purchased and may cause greater risk of
  loss.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital and income.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.44%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.02%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.46%            1 Year         3 Years         5 Years         10 Years
                                                                          $47             $148            $258            $579


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 43.16% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in equity securities of
large capitalization companies that may include both “growth” and “value” stocks, and may represent companies across all
market sectors. For this purpose, large capitalization equity investments are those whose market capitalizations are above the
largest stock in the bottom quartile of the S&P 500® Index ($6.46 billion as of December 31, 2010.)
In selecting investments, the adviser looks for companies with strong financial characteristics such as strong management teams,
solid balance sheets, consistent earnings growth, sustainable cash flows and leading market shares in their industries. The
Portfolio may be broadly diversified, potentially reflecting all sectors of the S&P 500® Index. Economic outlook and/or absolute
valuation determines the relative attractiveness of market sectors and sector weights may differ from those in the S&P 500®
Index, reflecting the economic outlook. The adviser may utilize options, futures contracts and swap agreements, to seek to
generate income or as alternatives to direct investments when the adviser deems it to be more efficient or advantageous. The
Portfolio may invest up to 20% of net assets in American Depositary Receipts and other securities of foreign issuers denominated
in U.S. dollars.


                                                               NMSF–7                       Northwestern Mutual Series Fund, Inc.
Large Cap Core Stock Portfolio
Under normal market conditions, the Portfolio attempts to achieve a gross income of at least 75% of the dividend yield of the
S&P 500® Index. However, this income level is merely a guideline, and there can be no certainty that this income level will be
achieved. The Portfolio may invest in both dividend paying and non-dividend paying stocks, including preferred stocks.
The Portfolio may sell securities for a variety of reasons, such as to secure gains, when the adviser perceives a significant change
in the outlook for a company or industry, or to make room in the Portfolio for more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a particular
  style of investing, such as growth or value or a combination of both, may underperform when the market does not favor the
  particular style used by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market
  conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 34.89% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of its net assets (plus any borrowings for investment purposes), in equity and equity
related securities of U.S. large capitalization companies. The Portfolio defines large capitalization companies as those with a
market capitalization range, at the time of investment, equal to that of the Portfolio’s benchmark, the S&P 500® Index. As of
December 31, 2010, the market capitalization range of the S&P 500® Index was $1.58 billion to $364.06 billion. In selecting
investments, greater consideration is given to potential appreciation and future dividends than to current income. From time to
time, the Portfolio also may invest in companies outside this market capitalization range.
The adviser uses a system of multiple portfolio managers in managing the Portfolio’s assets. Under this approach the Portfolio is
divided into segments managed by individual managers who decide how their respective segments will be invested. Portfolio
managers look across industry sectors in selecting stocks for the Portfolio, seeking quality companies at attractive prices. In
keeping with the adviser’s bottom-up philosophy, the weighting for any given sector reflects the portfolio managers’ assessments
and outlooks for individual companies within that sector. Weightings are arrived at through individual stock selection rather than
through top-down judgments.

                                                                                 Large Cap Blend Portfolio
The Portfolio may hold American Depositary Receipts and other securities of foreign issuers which are denominated in U.S.
dollars (up to 20% of net assets), as well as preferred stocks, securities convertible into common or preferred stocks, warrants and
rights.
The Portfolio may sell securities for a variety of reasons such as to secure gains, limit losses, or redeploy assets into more
promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a particular
  style of investing, such as growth or value or a combination of both, may underperform when the market does not favor the
  particular style used by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market
  conditions and investor sentiment.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid Cap Company Risk – Investing in mid cap stocks may cause greater risk of loss and price fluctuation than investing in
  stocks of larger cap companies due to a more limited track record, narrower product markets, more limited resources and less
  liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than stocks with larger
  capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is to achieve investment results that approximate the performance of the Standard &
Poor’s 500 Composite Stock Price Index (“S&P 500® Index”).

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.20%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.01%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.21%            1 Year         3 Years         5 Years         10 Years
                                                                          $22             $68             $118            $268


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 4.14% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio employs a “passive management,” or indexing, investment approach designed to track the performance of the S&P
500® Index. The S&P 500® Index is composed of the stocks of primarily large capitalization companies that represent a broad
spectrum of the U.S. economy and a substantial part of the U.S. stock market’s total capitalization. As of December 31, 2010, the
market capitalization range of the S&P 500® Index was $1.58 billion to $364.06 billion. The Portfolio attempts to achieve its
objective by investing all, or substantially all, of its assets in the stocks that make up the S&P 500® Index, holding each stock in
approximately the same proportion as its weighting in the Index. This is known as a full replication strategy. The Portfolio may
also invest in S&P 500® Index stock futures and swap agreements to help achieve full replication.
Standard & Poor’s constructs the Index by first identifying major industry categories and then allocating a representative sample
of the larger and more liquid stocks in those industries to the index. S&P weights each stock according to its float-adjusted
market value. For example, the 50 largest companies in the index may account for over 50% of its value. For this reason, the
Index 500 Stock Portfolio is classified as “nondiversified.”


                                                             NMSF–13                        Northwestern Mutual Series Fund, Inc.
Index 500 Stock Portfolio
The Index 500 Stock Portfolio’s ability to match the performance of the S&P 500® Index will be affected to some extent by the
size and timing of cash flows into and out of the Index 500 Stock Portfolio. The Portfolio will be managed with a view to
reducing such effects.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities.
• Indexing Strategy Risk – A Portfolio may not perform as well as the index it attempts to match due to the Portfolio’s
  expenses, changes in securities markets, changes in the composition of the underlying index and the timing of purchases and
  redemptions of Portfolio shares. A Portfolio using an indexing strategy does not attempt to manage market volatility, use
  defensive strategies or reduce the effects of any long-term periods of poor stock performance. In addition, changes in the value
  of a derivative used to replicate an index may not correlate as intended with the underlying index.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Nondiversification Risk – The Portfolio is classified as a nondiversified fund to enable it to hold securities in the same
  weightings as its underlying Index. Depending on the composition of the Index from time to time, the Portfolio may invest a
  relatively large percentage of its assets in a single issuer or small number of issuers, and its performance may be more closely
  tied to the value of that one issuer or issuers and may be more volatile than the performance of a more diversified fund.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

SUMMARY PROSPECTUS
MAY 1, 2011                                                            Large Company Value Portfolio

   dated May 1, 2011, along with the Portfolio’s most recent annual report dated December 31, 2010, are incorporated by
   reference into this Summary Prospectus. The Portfolio’s statement of additional information and annual report may be
   obtained, free of charge, in the same manner as the prospectus.



INVESTMENT OBJECTIVE
The Portfolio’s investment objective is to seek long-term capital growth. Income is a secondary objective.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or life insurance policy. The fees and
expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity contracts or
variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable life
insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.72%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.08%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.80%            1 Year         3 Years         5 Years         10 Years
                                                                          $82             $255            $444            $990


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 29.84% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio invests primarily in larger companies. Accordingly, the Portfolio will normally have at least 80% of its net assets
(plus any borrowings for investment purposes) in equity securities of companies comprising the Russell 1000® Index. As of
December 31, 2010, the market capitalization range of the Russell 1000® Index was $251.2 million to $364.06 billion. From time
to time, the Portfolio also may invest in companies outside this market capitalization range.
The adviser looks for stocks of companies that it believes are undervalued at the time of purchase. The adviser uses a value
investment strategy that looks for companies that are temporarily out of favor in the market. The adviser attempts to purchase the
stocks of these undervalued companies and hold each stock until it has returned to favor in the market and the price has increased
to, or is higher than, a level the adviser believes more accurately reflects the fair value of the company.
Companies may be undervalued due to market declines, poor economic conditions, actual or anticipated bad news regarding the
issuer or its industry, or because they have been overlooked by the market. To identify these companies, the adviser looks for
companies with earnings, cash flows and/or assets that may not be reflected accurately in the companies’ stock prices. The
adviser also may consider whether the companies’ securities have a favorable income-paying history and whether income
payments are expected to continue or increase.

Northwestern Mutual Series Fund, Inc.                        NMSF–16
                                                                       Large Company Value Portfolio
While most assets will be invested in U.S. common stocks, other securities may also be purchased, including preferred stocks,
warrants and securities convertible into common or preferred stocks, in keeping with the Portfolio’s objectives. When the adviser
believes it is prudent, the Portfolio may invest a portion of its assets in foreign securities and American Depositary Receipts (up
to 20% of net assets), debt securities of companies, debt obligations of governments and their agencies, and other similar
securities and utilize forwards, options and futures for cash management purposes or to hedge foreign currency exposure.
The adviser may sell stocks from the Portfolio if it believes a stock no longer meets established valuation criteria.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Debt Obligations of Foreign Governments Risk – The issuer of the foreign debt or the governmental authorities that control
  the repayment of such debt may be unable or unwilling to repay principal or interest when due, and the Portfolio may have
  limited recourse in the event of a default. The market prices of debt obligations of governments and their agencies, and the
  Portfolio’s net asset value, may be more volatile than prices of U.S. debt obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid Cap Company Risk – Investing in mid cap stocks may cause greater risk of loss and price fluctuation than investing in
  stocks of larger cap companies due to a more limited track record, narrower product markets, more limited resources and less
  liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than stocks with larger
  capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital and income.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.56%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.02%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.58%            1 Year         3 Years         5 Years         10 Years
                                                                          $59             $186            $324            $726


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 48.18% of the average value of its portfolio.

Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in equity securities of
U.S. issuers and securities whose principal markets are in the U.S., including American Depositary Receipts and other securities
of foreign issuers denominated in U.S. dollars. Generally, the companies in which the Portfolio invests will have a market value
of $1 billion or more.
Reflecting a value approach to investing, the adviser generally attempts to keep Portfolio assets invested in securities that exhibit
one or more value characteristics relative to the market norms reflected in the S&P 500® Index. These value characteristics
include below market price to earnings ratios, below market price to book ratios, and dividend yields that are equal to or above
the market norms. While most assets will be invested in U.S. common stocks, other securities may also be purchased, including
preferred stocks, rights, warrants, and securities convertible into common or preferred stocks. Up to 20% of the Portfolio’s net
assets may be invested in foreign securities.
The adviser uses a system of multiple portfolio managers in managing the Portfolio’s assets. Under this approach, the Portfolio is
divided into segments managed by individual managers who decide how their respective segments will be invested. Based on the


                                                             NMSF–19                        Northwestern Mutual Series Fund, Inc.
Domestic Equity Portfolio
research carried out by the adviser’s analysts, management looks across industry sectors in selecting stocks for the Portfolio. With
a long-term perspective, management looks for quality companies at attractive prices that will outperform their peers and the
benchmark over time. In keeping with its bottom-up philosophy, the weighting for any given sector reflects the adviser’s
assessments and outlooks for individual companies within that sector. Weightings are arrived at through individual stock
selection rather than through top-down judgments.
The Portfolio may sell securities for a variety of reasons such as to secure gains, limit losses, or redeploy assets into more
promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid Cap Company Risk – Investing in mid cap stocks may cause greater risk of loss and price fluctuation than investing in
  stocks of larger cap companies due to a more limited track record, narrower product markets, more limited resources and less
  liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than stocks with larger
  capitalizations.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital and income.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.65%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.02%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.67%            1 Year         3 Years         5 Years         10 Years
                                                                          $68             $214            $373            $835


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 11.14% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in common stocks, with
65% in the stocks of well established companies paying dividends. Under normal market conditions, the Portfolio will seek to
have a dividend yield exceeding, on average, the dividend yield of the S&P 500® Index. This level is merely a guideline and there
can be no certainty this level will be achieved.
The Portfolio will typically employ a value approach in selecting investments. The adviser’s in-house research team seeks to
identify companies that appear to be undervalued by various measures and may be temporarily out of favor, but have good
prospects for capital appreciation and dividend growth.
The adviser has the discretion to deviate from the Portfolio’s normal investment criteria, as described above, and purchase
securities the adviser believes could provide an opportunity for substantial appreciation. These special situations might arise when
the adviser believes a security could increase in value for a variety of reasons, including a change in management, an
extraordinary corporate event, a new product introduction or a favorable competitive development.

While most assets will be invested in U.S. common stocks, other securities may also be purchased, including preferred stocks,
foreign securities and American Depositary Receipts (up to 20% of net assets), and debt securities, including high yield debt
securities (so called “junk bonds”) in keeping with the Portfolio’s objectives. Up to 10% of the Portfolio’s net assets may be
invested in high yield debt securities and loans.
The Portfolio may sell securities for a variety of reasons such as to secure gains, limit losses, or redeploy assets into more
promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk, may
  be more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Special Situation Risk – The risk that the change or event anticipated by the adviser when purchasing a company might not
  occur or attract the expected attention, which could have a negative impact on the price of the issuer's securities. Investing in
  special situations may involve heightened volatility in the value of the securities purchased and may cause greater risk of loss.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.53%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.01%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.54%            1 Year         3 Years         5 Years         10 Years
                                                                            $55           $173            $302            $677


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 41.04% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in stocks of mid-sized
companies. In keeping with its growth strategy, the Portfolio selects companies for their above average growth potential, giving
consideration to factors such as company management, growth rate of revenues and earnings, opportunities for margin expansion,
strong financial characteristics and attractive valuations.
For purposes of the Portfolio’s investment strategy, mid-sized companies are those with market capitalizations that fall within the
range of the Russell Midcap® Growth Index at the time of purchase (as of December 31, 2010, from approximately $752.4
million to $21.53 billion). The Portfolio invests primarily in common stocks. The Portfolio may invest up to 20% of net assets in
American Depositary Receipts and other securities of foreign issuers, and may use futures, options, swap agreements and
exchange-traded funds as a cash management strategy.
The Portfolio may sell a stock when it has reached the adviser’s valuation target, when the adviser does not anticipate further
appreciation, when a company’s growth prospects change materially or to redeploy assets into more promising opportunities.

Mid Cap Growth Stock Portfolio
PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a growth
  style of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the
  Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid and Small Cap Company Risk – Investing in mid and small cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

                                                                    mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem

* The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 9.93% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio employs a “passive management,” or indexing, investment approach designed to track the performance of the S&P
MidCap 400® Index. The S&P MidCap 400® Index is composed of the stocks of companies whose capitalizations generally are
smaller than those of companies that comprise the S&P 500® Index. The S&P MidCap 400® Index does not include the very
large issues that account for most of the weighting in the S&P 500® Index. As of December 31, 2010, the market capitalization
range of the S&P MidCap 400® Index was $461.3 million to $9.22 billion. The Portfolio attempts to achieve its objective by


Northwestern Mutual Series Fund, Inc.                        NMSF–28
                                                                                  Index 400 Stock Portfolio
investing all, or substantially all, of its assets in the stocks that make up the S&P MidCap 400® Index, holding each stock in
approximately the same proportion as its weighting in the Index. This is known as a full replication strategy. The Portfolio may
also invest in S&P MidCap 400® Index stock futures and swap agreements to help achieve full replication.
Standard & Poor’s constructs the index by first identifying major industry categories and then allocating a representative sample
of the larger and more liquid stocks in those industries to the index. S&P weights each stock according to its float-adjusted
market value. For example, the 50 largest companies in the index may account for over 50% of its value. For this reason, the
Index 400 Stock Portfolio is classified as “nondiversified.”
The Index 400 Stock Portfolio’s ability to match the performance of the S&P MidCap 400® Index will be affected to some extent
by the size and timing of cash flows into and out of the Index 400 Stock Portfolio. The Portfolio will be managed with a view to
reducing such effects.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities.
• Indexing Strategy Risk – A Portfolio may not perform as well as the index it attempts to match due to the Portfolio’s
  expenses, changes in securities markets, changes in the composition of the underlying index and the timing of purchases and
  redemptions of Portfolio shares. A Portfolio using an indexing strategy does not attempt to manage market volatility, use
  defensive strategies or reduce the effects of any long-term periods of poor stock performance. In addition, changes in the value
  of a derivative used to replicate an index may not correlate as intended with the underlying index.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Nondiversification Risk – The Portfolio is classified as a nondiversified fund to enable it to hold securities in the same
  weightings as its underlying Index. Depending on the composition of the Index from time to time, the Portfolio may invest a
  relatively large percentage of its assets in a single issuer or small number of issuers, and its performance may be more closely
  tied to the value of that one issuer or issuers and may be more volatile than the performance of a more diversified fund.
• Mid and Small Cap Company Risk – Investing in mid and small cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term capital growth. Current income is a secondary objective.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.85%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.07%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.92%            1 Year         3 Years         5 Years         10 Years
                                                                          $94             $293            $509           $1,131


Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 121.65% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in equity securities of
mid-sized companies. The Portfolio invests primarily in a diversified portfolio of equity securities of mid-sized companies that
are determined by Portfolio’s adviser to be undervalued. At the time of investment, companies purchased typically will fall within
the capitalization range of the Russell 3000® Index, excluding the largest 100 such companies ($7.2 million to $29.14 billion as
of December 31, 2010). The adviser intends to manage the Portfolio so that its weighted capitalization falls within the
capitalization range of the members of the Russell MidCap® Index ($251.2 million to $38.54 billion as of December 31, 2010).
In managing the Portfolio, the adviser uses its own fundamental value approach. In selecting securities for the Portfolio, the
adviser attempts to identify companies whose long-term earnings, cash flows and/or assets are not reflected in the current market
price of their securities and hold each security until it has returned to favor in the market and the price has increased to, or is
higher than a level the adviser believes more accurately reflects the fair value of the company. The adviser may also consider
whether the companies’ securities have a favorable income-paying history and whether income payments are expected to
continue or increase.


                                                             NMSF–31                        Northwestern Mutual Series Fund, Inc.
Mid Cap Value Portfolio
While most assets will be invested in U.S. common stocks, other securities may also be purchased, including preferred stocks,
warrants and securities convertible into common or preferred stocks, in keeping with the Portfolio’s objectives. The Portfolio may
invest in American Depositary Receipts and foreign securities (up to 20% of net assets) and may enter into forward commitments
to seek to hedge the Portfolio’s foreign currency exposure and utilize other derivatives transactions, such as options, futures, and
swap agreements as a cash management strategy.
The adviser may sell a stock from the Portfolio if it believes the stock no longer meets established valuation criteria, the stock’s
risk parameters outweigh its return opportunity, specific events alter a stock’s prospects or more attractive opportunities are
identified. In seeking to achieve its investment objective, the adviser may sell shares from the Portfolio without regard to the
length of time a security has been held.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• High Portfolio Turnover Risk – Active and frequent trading may cause higher brokerage expenses and other transaction
  costs, which may adversely affect the Portfolio’s performance.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mid and Small Cap Company Risk – Investing in mid and small cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

SUMMARY PROSPECTUS
MAY 1, 2011                                                       Small Cap Growth Stock Portfolio

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                Example
    (fees paid directly from your investment)            N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
    Management Fee                                      0.56%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees               None
                                                                    Although your actual costs may be higher or lower, based on
    Other Expenses                                      0.04%       these assumptions your costs would be:
    Total Annual Portfolio Operating Expenses*          0.60%            1 Year         3 Years         5 Years         10 Years

*
                                                                            $61           $192            $335            $750
  The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 74.54% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in common stocks of
U.S. companies with market capitalizations that do not exceed the maximum market capitalizations of any security in the Russell
2000® Growth Index at the time of purchase (as of December 31, 2010, from approximately $7.2 million to $5.3 billion). The
Portfolio may also invest in the equity securities of micro cap companies (defined as companies with stock market capitalizations
less than $500 million at the time of investment). The Portfolio may also invest up to 20% of net assets in American Depositary
Receipts and other securities of foreign issuers which are denominated in U.S. dollars.
The adviser employs a growth strategy, selecting securities for their above average growth potential giving consideration to
factors such as, for example, company management, growth rate of revenues and earnings, opportunities for margin expansion
and strong financial characteristics.

Northwestern Mutual Series Fund, Inc.                        NMSF–34
                                                                  Small Cap Growth Stock Portfolio
While most assets will be invested in U.S. common stocks, other securities may also be purchased, including preferred stocks,
warrants and securities convertible into common or preferred stocks, in keeping with the Portfolio’s objectives. The Portfolio may
also utilize derivative securities, including options, futures or swap agreements to protect against downside risk, to seek to
enhance returns, as a cash management strategy or to gain exposure to certain sectors as alternatives to direct investments, when
the adviser deems it to be more efficient or advantageous.
A security will generally be sold when it meets the adviser’s price target. The Portfolio may sell securities for a variety of other
reasons including to limit losses or to redeploy assets into more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a growth
  style of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the
  Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Liquidity Risk – Particular investments, such as restricted securities, small and micro cap stocks, foreign securities and
  derivatives, may be difficult to purchase or sell at an advantageous time or price, if at all. These risks may be magnified during
  periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Micro Cap Company Risk – Investing in micro cap stocks may cause the Portfolio to experience more rapid and extreme
  changes in value than a fund that invests solely in small, mid and large cap stocks due to a more limited track record, narrower
  product markets, more limited resources, higher risk of failure, and less liquid trading markets.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

     and its risks. You can find the Portfolio’s prospectus and other information about the Portfolio online at
     www.nmseriesfund.com. You can also get this information at no cost by calling 1-888-455-2232 or by sending an e-mail
     request to sfprospectus@northwesternmutual.com. The current prospectus and statement of additional information, each
     dated May 1, 2011, along with the Portfolio’s most recent annual report dated December 31, 2010, are incorporated by

INVESTMENT OBJECTIVE
The Portfolio’s investment objective is to achieve investment results that approximate the performance of the Standard & Poor’s
SmallCap 600® Index (“S&P SmallCap 600® Index”).

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                Example
    (fees paid directly from your investment)           N/A         This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
    Management Fee                                      0.25%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees               None
                                                                    Although your actual costs may be higher or lower, based on
    Other Expenses                                      0.18%       these assumptions your costs would be:

    Expense Reimbursement                              (0.07)%            $37             $129            $231            $533
    Total Annual Portfolio Operating Expenses After
    Expense Reimbursement*,**                           0.36%

*  The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).
** The Portfolio’s investment adviser has entered into a written

expense limitation agreement under which it has agreed to
limit the total expenses of the Portfolio (excluding taxes,
brokerage, other investment-related costs, interest and
dividend expenses and charges and extraordinary expenses) to
an annual rate of 0.35% of the Portfolio’s average net assets.
This expense limitation agreement may be terminated by the
adviser at any time after April 30, 2012.

Index 600 Stock Portfolio
Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 46.88% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio employs a “passive management,” or indexing, investment approach designed to track the performance of the
S&P® 600 Index. The S&P® 600 Index is composed of 600 domestic stocks with market capitalizations ranging between
approximately $69.3 million and $3.24 billion as of December 31, 2010. The Portfolio attempts to achieve its objective by
investing all, or substantially all, of its assets in stock that make up the S&P® 600 Index, holding each stock in approximately the
same proportion as its weighting in the Index. This is known as a full replication strategy. The Portfolio may also invest in
exchange traded funds, futures contracts and swap agreements for cash management purposes and to help achieve full replication.
Standard & Poor’s constructs the index by first identifying major industry categories and then allocating a representative sample
of the larger and more liquid stocks in those industries to the index. S&P weights each stock according to its float-adjusted
market value. For example, the 50 largest companies in the index may account for over 50% of its value. For this reason, the
Index 600 Stock Portfolio is classified as “nondiversified.”
The Index 600 Stock Portfolio’s ability to match the performance of the S&P® 600 Index will be affected to some extent by the
size and timing of cash flows into and out of the Index 600 Stock Portfolio. The Portfolio will be managed with a view to
reducing such effects.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Indexing Strategy Risk – A Portfolio may not perform as well as the index it attempts to match due to the Portfolio’s
  expenses, changes in securities markets, changes in the composition of the underlying index and the timing of purchases and
  redemptions of Portfolio shares. A Portfolio using an indexing strategy does not attempt to manage market volatility, use
  defensive strategies or reduce the effects of any long-term periods of poor stock performance. In addition, changes in the value
  of a derivative used to replicate an index may not correlate as intended with the underlying index.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Nondiversification Risk – The Portfolio is classified as a nondiversified fund to enable it to hold securities in the same
  weightings as its underlying Index. Depending on the composition of the Index from time to time, the Portfolio may invest a
  relatively large percentage of its assets in a single issuer or small number of issuers, and its performance may be more closely
  tied to the value of that one issuer or issuers and may be more volatile than the performance of a more diversified fund.



Northwestern Mutual Series Fund, Inc.                        NMSF–38
                                                                                   Index 600 Stock Portfolio
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

     Before you invest, you may want to review the Portfolio’s prospectus, which contains more information about the Portfolio
     and its risks. You can find the Portfolio’s prospectus and other information about the Portfolio online at
     www.nmseriesfund.com. You can also get this information at no cost by calling 1-888-455-2232 or by sending an e-mail

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                Example
    (fees paid directly from your investment)            N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
    Management Fee                                      0.85%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees               None
                                                                    Although your actual costs may be higher or lower, based on
    Other Expenses                                      0.02%       these assumptions your costs would be:
    Acquired Fund Fees and Expenses                     0.21%            1 Year         3 Years         5 Years         10 Years
    Total Annual Portfolio Operating Expenses*          1.08%               $110          $343            $595           $1,317

* The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 11.51% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets in common stocks of companies with market capitalizations that do not
exceed the maximum market capitalization of any security in the S&P® Small Cap 600 Index at the time of purchase (as of
December 31, 2010, from approximately $69.3 million to $3.24 billion). The market capitalization of companies in the Portfolio
and the Index changes over time and the Portfolio will not sell a stock just because the company has grown to a market
capitalization outside of the range. The Portfolio may also invest in the equity securities of micro cap companies (defined as
companies with stock market capitalizations less than $500 million at the time of investment).



Northwestern Mutual Series Fund, Inc.                        NMSF–40
                                                                                 Small Cap Value Portfolio
Reflecting a value approach to investing, the Portfolio will seek the stocks of companies whose current stock prices do not appear
to adequately reflect their underlying value as measured by assets, earnings, cash flow or business franchises. The in-house
research team at the adviser seeks to identify companies that appear to be undervalued by various measures, and may be
temporarily out of favor, but have good prospects for capital appreciation. Consideration is also given to industry weightings in
an attempt to keep the Portfolio broadly diversified among economic sectors.
In pursuing its investment objective, the adviser has the discretion to deviate from its normal investment criteria, as described
above, and purchase securities the adviser believes could provide an opportunity for substantial appreciation. These special
situations might arise when the adviser believes a security could increase in value for a variety of reasons, including a change in
management, an extraordinary corporate event, a new product introduction or innovation, or a favorable competitive
environment.
While most assets will be invested in U.S. common stocks, other securities may also be purchased, including American
Depositary Receipts and foreign securities (up to 20% of net assets), and securities of other other investment companies,
including open-end funds, closed-end funds, exchange-traded funds and business development companies, in keeping with the
Portfolio’s objectives.
The Portfolio may sell securities for a variety of reasons, such as to secure gains, limit losses or redeploy assets into more
promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar and may be less liquid, more volatile, and harder to value than U.S.
  securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political,
  business and social frameworks to support securities markets.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Micro Cap Company Risk – Investing in micro cap stocks may cause the Portfolio to experience more rapid and extreme
  changes in value than a fund that invests solely in small, mid and large cap stocks due to a more limited track record, narrower
  product markets, more limited resources, higher risk of failure, and less liquid trading markets.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.
• Special Situation Risk – The risk that the change or event anticipated by the adviser when purchasing a company might not
  occur or attract the expected attention, which could have a negative impact on the price of the company's securities. Investing
  in special situations may involve heightened volatility in the value of the securities purchased and may cause greater risk of
  loss.

varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is long-term growth of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                      Example
 (fees paid directly from your investment)                 N/A         This Example is intended to help you compare the cost of
                                                                       investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                       mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                       in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                       all of your shares at the end of those periods. The Example
 Management Fee                                           0.68%        also assumes that your investment has a 5% return each year
                                                                       and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                     None
                                                                       Although your actual costs may be higher or lower, based on
 Other Expenses                                           0.13%        these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses                0.81%             1 Year          3 Years          5 Years         10 Years
                                                                              $83             $259             $450           $1,002

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 150.91% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio will invest at least 80% of net assets (plus any borrowings for investment purposes) in the securities of
issuers from countries outside the United States. The Portfolio normally invests in a core group of equity securities of 60-100 issuers.
The Portfolio may invest in emerging markets but will normally limit such investments to 20% of its net assets, measured at the time
of purchase. The Portfolio may invest a relatively large percentage of its assets in a single country, a small number of countries, or a
particular geographic region. Although the Portfolio intends to invest substantially all of its assets in issuers located outside the U.S.,
it may at times invest in U.S. issuers. The Portfolio’s investments in equity securities may include small, medium, and large
capitalization issues. Although the Portfolio invests primarily in foreign common stocks and American Depositary Receipts, within
the parameters of its specific investment policies, the Portfolio may invest in domestic equity and debt securities.
The adviser applies a “bottom up” approach in choosing investments. In other words, the adviser looks at companies one at a time
to determine if a company is an attractive investment opportunity and if it is consistent with the Portfolio’s investment policies.
The Portfolio invests in companies after assessing their growth potential. If the adviser is unable to find such investments, the
Portfolio’s uninvested assets may be held in cash or similar investments, subject to the Portfolio’s specific investment policies.
The adviser normally seeks to limit any sector exposure and country exposure to plus or minus 10% of the respective weighting
of the Morgan Stanley Capital International EAFE® Index.

                                                                NMSF–43                         Northwestern Mutual Series Fund, Inc.
International Growth Portfolio
The Portfolio may reduce its position in a particular holding in order to secure gains, if there is a deterioration in the holding’s
fundamentals or to make room in the Portfolio for more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a growth
  style of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the
  Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Emerging Markets Risk – Investing in emerging market securities increases foreign investing risk, and may subject the
  Portfolio to more rapid and extreme changes in value or more losses than a fund that invests exclusively in U.S. securities or in
  foreign, developed countries. This risk is due to smaller markets, illiquidity, significant price and market volatility, currency,
  interest rate and commodity price fluctuations, restrictions on foreign investment, changes in tax policy, differing securities
  market structures, higher transaction costs, and various administrative difficulties, such as delays in executing, clearing and
  settling portfolio transactions or in receiving payment of dividends.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Focus Risk – The Portfolio’s performance could be more closely tied to the value of a single security or small number of
  securities because, although diversified, the Portfolio may hold large positions in a single or small number of securities. As a
  result, the Portfolio’s performance could be more volatile than the performance of funds that hold a greater number of
  securities.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar.
  Investments in securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses
  than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities.
• Geographic Concentration Risk – The Portfolio’s performance could be more volatile than that of a more geographically
  diversified fund as a result of the Portfolio investing a relatively large percentage of its assets in issuers located in a single
  country, a small number of countries, or a particular geographic region. Also, the Portfolio’s performance may be more closely
  tied to the market, currency, economic, political, or regulatory conditions in those countries or that region.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Liquidity Risk – Particular investments, such as restricted securities, small and micro cap stocks, foreign securities and
  derivatives, may be difficult to purchase or sell at an advantageous time or price, if at all. These risks may be magnified during
  periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.

• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is to seek capital appreciation.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                 Example
    (fees paid directly from your investment)           N/A          This Example is intended to help you compare the cost of
                                                                     investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                     mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                     in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                     all of your shares at the end of those periods. The Example
    Management Fee                                      0.88%        also assumes that your investment has a 5% return each year
                                                                     and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees               None
                                                                     Although your actual costs may be higher or lower, based on
    Other Expenses                                      0.50%        these assumptions your costs would be:
    Total Annual Portfolio Operating Expenses           1.38%            1 Year         3 Years         5 Years         10 Years
    Expense Reimbursement                              (0.23)%               $117         $406            $726           $1,630
    Total Annual Portfolio Operating Expenses After
    Expense Reimbursement*                              1.15%

* The Portfolio’s investment adviser has entered into a written
expense limitation agreement under which it has agreed to
limit the total expenses of the Portfolio (excluding taxes,
brokerage, other investment-related costs, interest and
dividend expenses and charges, and extraordinary expenses) to
an annual rate of 1.15% of the Portfolio’s average net assets.
This expense limitation agreement may be terminated by the
adviser at any time after April 30, 2012.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 47.90% of the average value of its portfolio.

                                                            Research International Core Portfolio
PRINCIPAL INVESTMENT STRATEGIES
The Portfolio normally invests primarily in foreign equity securities, including emerging market equity securities. The Portfolio
may invest a relatively large percentage of its assets in issuers in a single country, a small number of countries, or a particular
geographic region.

A team of investment research analysts selects investments for the Portfolio. The adviser allocates the Portfolio’s assets to
analysts by broad market sectors, which generally approximate the sector weightings in the MSCI EAFE® Index. The Portfolio is
not constrained to any particular investment style. The adviser may invest the Portfolio’s assets in the stocks of companies it
believes to have above average earnings growth potential compared to other companies (growth companies), and in the stocks of
companies it believes are undervalued compared to their perceived worth (value companies), or in a combination of growth and
value companies. The Portfolio’s investments in equity securities may include small, medium and large capitalization companies,
and could include common stocks, preferred stocks, securities convertible into stock and depositary receipts for those securities.

The adviser uses a bottom-up investment approach to buying and selling investments for the Portfolio. Investments are selected
primarily based on fundamental analysis of individual issuers and their potential in light of their current financial condition, and
market, economic, political and regulatory conditions. Factors considered may include analysis of an issuer’s earnings, cash
flows, competitive position and management ability. Quantitative models that systematically evaluate an issuer’s valuation, price
and earning momentum, earnings quality and other factors may also be considered.

While the adviser may use derivatives, including futures, forward contracts, options and swaps, for any investment purpose, the
adviser expects to use derivatives primarily to increase or decrease exposure to a particular market, segment of the market or
security. In seeking to achieve its investment objective, the Portfolio may engage in active and frequent trading.

The Portfolio may sell securities for a variety of reasons such as to seek to secure gains, limit losses, or redeploy assets into
opportunities believed to be more promising, among others.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.

• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a particular
  style of investing, such as growth or value or a combination of both, may underperform when the market does not favor the
  particular style used by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market
  conditions and investor sentiment.

• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.

• Emerging Markets Risk – Investing in emerging market securities increases foreign investing risk, and may subject the
  Portfolio to more rapid and extreme changes in value or more losses than a fund that invests exclusively in U.S. securities or in
  foreign, developed countries. This risk is due to smaller markets, illiquidity, significant price and market volatility, currency,
  interest rate and commodity price fluctuations, restrictions on foreign investment, changes in tax policy, differing securities
  market structures, higher transaction costs, and various administrative difficulties, such as delays in executing, clearing and
  settling portfolio transactions or in receiving payment of dividends.

• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.

                                                             NMSF–47                       Northwestern Mutual Series Fund, Inc.
Research International Core Portfolio
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar.
  Investments in securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses
  than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities.
• Geographic Concentration Risk – The Portfolio’s performance could be more volatile than that of a more geographically
  diversified fund as a result of the Portfolio investing a relatively large percentage of its assets in issuers located in a single
  country, a small number of countries, or a particular geographic region. Also, the Portfolio’s performance may be more closely
  tied to the market, currency, economic, political, or regulatory conditions in those countries or that region.
• High Portfolio Turnover Risk – Active and frequent trading may cause higher brokerage expenses and other transaction
  costs, which may adversely affect the Portfolio’s performance.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Liquidity Risk – Particular investments, such as restricted securities, small and micro cap stocks, foreign securities and
  derivatives, may be difficult to purchase or sell at an advantageous time or price, if at all. These risks may be magnified during
  periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

    (expenses that you pay each year as a percentage

* The Portfolio’s investment adviser has entered into a written
agreement to waive a portion of its management fee, such that
the management fee is 0.80% on the Portfolio’s first $50
million of assets, 0.60% on assets from $50 million to $1
billion and 0.58% on assets from $1 billion to $1.5 billion.
This fee waiver agreement may be terminated by the adviser
at any time after April 30, 2012.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 28.57% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in equity securities and at
least 65% of net assets in securities of issuers from a minimum of three countries outside the U.S. The Portfolio has an unlimited
right to purchase securities in any foreign country, developed or undeveloped. From time to time, based on economic conditions,
the Portfolio may have significant investments in one or more countries or in particular sectors.

Northwestern Mutual Series Fund, Inc.                          NMSF–50
                                                                            International Equity Portfolio
The Portfolio’s investments in equity securities may include small, medium and large capitalization issues that the Portfolio’s
adviser believes are undervalued. The strategy for the Portfolio will reflect a bottom-up, value oriented and long-term investment
philosophy. In choosing equity investments, the adviser will focus on the market price of a company’s securities in relation to the
company’s long-term earnings (typically 5 years), asset value and cash flow potential. A company’s historical value measures,
including price/earnings ratio, profit margins and liquidation value, will also be considered. The Portfolio invests primarily in
foreign common stocks.
The adviser may consider selling an equity security when it believes the security has become overvalued due to either its price
appreciation or changes in the company’s fundamentals.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a value style
  of investing, such as the Portfolio, may underperform when the market does not favor the particular style used by the Portfolio.
  Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment.
• Emerging Markets Risk – Investing in emerging market securities increases foreign investing risk, and may subject the
  Portfolio to more rapid and extreme changes in value or more losses than a fund that invests exclusively in U.S. securities or in
  foreign, developed countries. This risk is due to smaller markets, illiquidity, significant price and market volatility, currency,
  interest rate and commodity price fluctuations, restrictions on foreign investment, changes in tax policy, differing securities
  market structures, higher transaction costs, and various administrative difficulties, such as delays in executing, clearing and
  settling portfolio transactions or in receiving payment of dividends.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities may be adversely affected
  by decreases in foreign currency values relative to the U.S. dollar. Investments in securities subject to foreign currency risk
  may have more rapid and extreme changes in value or more losses than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities and may be less liquid, more volatile, and
  harder to value than U.S. securities.
• Geographic Concentration Risk – The Portfolio’s performance could be more volatile than that of a more geographically
  diversified fund as a result of the Portfolio investing a relatively large percentage of its assets in issuers located in a single
  country, a small number of countries, or a particular geographic region. Also, the Portfolio’s performance may be more closely
  tied to the market, currency, economic, political, or regulatory conditions in those countries or that region.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

expense limitation agreement under which it has agreed to
limit the total expenses of the Portfolio (excluding taxes,
brokerage, other investment-related costs, interest and
dividend expenses and charges, and extraordinary expenses) to

This expense limitation agreement may be terminated by the
adviser at any time after April 30, 2012.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 51.60% of the average value of its portfolio.

Emerging Markets Equity Portfolio
PRINCIPAL INVESTMENT STRATEGIES
The Portfolio normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in equity securities of
issuers that are tied economically to emerging market countries. Such equity securities may include common stocks, preferred
stocks, securities convertible into stock and depositary receipts for those securities. Emerging market countries may include
countries determined by the Portfolio’s adviser to have emerging market economies, taking into account a number of factors,
including whether a particular country has a low to middle economy according to the International Bank for Reconstruction and
Development (the World Bank), the country’s foreign currency debt rating, its political and economic stability, and the
development of its financial and capital markets. Currently, such countries are located in Latin America, Asia, Africa, the Middle
East, and the developing countries of Europe, primarily Eastern Europe. In seeking to achieve its investment objective, the
Portfolio may engage in active and frequent trading.
The Portfolio may invest in companies of any size. Although the Portfolio is diversified, the Portfolio may invest a relatively
large percentage of its assets in a single issuer or a small number of issuers. The adviser may invest a relatively large percentage
of the Portfolio’s assets in issuers in a single country, a small number of countries, or a particular geographic region.
The adviser uses a bottom-up investment approach to buying and selling investments for the Portfolio. Investments are selected
primarily based on fundamental analysis of individual issuers and their potential in light of their current financial condition, and
market, economic, political, and regulatory conditions. Factors considered may include analysis of an issuer’s earnings, cash
flows, competitive position and management ability. Quantitative models that systematically evaluate an issuer’s valuation, price
and earnings momentum, earnings quality and other factors may also be considered.
The Portfolio may sell securities for a variety of reasons such as to seek to secure gains, limit losses, or redeploy assets into
opportunities believed to be more promising, among others.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a particular
  style of investing, such as growth or value or a combination of both, may underperform when the market does not favor the
  particular style used by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market
  conditions and investor sentiment.
• Emerging Markets Risk – Investing in emerging market securities increases foreign investing risk, and may subject the
  Portfolio to more rapid and extreme changes in value or more losses than a fund that invests exclusively in U.S. securities or in
  foreign, developed countries. This risk is due to smaller markets, illiquidity, significant price and market volatility, currency,
  interest rate and commodity price fluctuations, restrictions on foreign investment, changes in tax policy, differing securities
  market structures, higher transaction costs, and various administrative difficulties, such as delays in executing, clearing and
  settling portfolio transactions or in receiving payment of dividends.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Focus Risk – The Portfolio’s performance could be more closely tied to the value of a single security or small number of
  securities because, although diversified, the Portfolio may hold large positions in a single or small number of securities. As a
  result, the Portfolio’s performance could be more volatile than the performance of funds that hold a greater number of
  securities.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar.
  Investments in securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses
  than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,

  political and economic conditions or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities.
• Geographic Concentration Risk – The Portfolio’s performance could be more volatile than that of a more geographically
  diversified fund as a result of the Portfolio investing a relatively large percentage of its assets in issuers located in a single
  country, a small number of countries, or a particular geographic region. Also, the Portfolio’s performance may be more closely
  tied to the market, currency, economic, political, or regulatory conditions in those countries or that region.
• High Portfolio Turnover Risk – Active and frequent trading may cause higher brokerage expenses and other transaction
  costs, which may adversely affect the Portfolio’s performance.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Liquidity Risk – Particular investments, such as restricted securities, small and micro cap stocks, foreign securities and
  derivatives, may be difficult to purchase or sell at an advantageous time or price, if at all. These risks may be magnified during
  periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Micro Cap Company Risk – Investing in micro cap stocks may cause the Portfolio to experience more rapid and extreme
  changes in value than a fund that invests solely in small, mid and large cap stocks due to a more limited track record, narrower
  product markets, more limited resources higher risk of failure, and less liquid trading markets.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is to realize maximum current income to the extent consistent with liquidity and
stability of capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio invests only in high quality, short term money market instruments that present minimal credit risks, as determined
by management. While the Portfolio seeks to achieve its investment objective by investing primarily in a diversified portfolio of
money market securities that are in the highest rating category for short-term obligations, it also may invest up to 3% of total
assets in money market securities that are in the second-highest rating category for short-term obligations. The Portfolio may
invest only in U.S. dollar denominated securities that mature in 397 days or fewer from the date of purchase.
The Portfolio primarily invests in the following types of securities: obligations of the U.S. Government (including its agencies
and instrumentalities); short-term corporate debt securities of domestic and foreign corporations; obligations of domestic and
foreign commercial banks, savings banks, and savings and loan associations; commercial paper; and repurchase agreements. The
Portfolio may invest more than 25% of its total assets in securities or obligations issued by U.S. banks. The Portfolio’s
investments will comply with applicable rules governing the quality, maturity, liquidity and diversification of securities held by
money market funds.
The Portfolio attempts to maximize its return by trading to take advantage of changing money market conditions and trends. The
Portfolio will also trade to take advantage of what are believed to be disparities in yield relationships between different money
market instruments. This procedure may increase or decrease the Portfolio’s yield depending upon management’s ability to
correctly time and execute such transactions.
Because the Portfolio intends to purchase only securities that mature in 397 days or fewer from the date of purchase, the level of
purchases will be relatively high. However, as transaction costs on Portfolio investments are generally not substantial, the high
level of purchases is not expected to adversely affect the Portfolio’s net asset value or net income.

                                                             NMSF–57                        Northwestern Mutual Series Fund, Inc.
Money Market Portfolio
An investment in the Money Market Portfolio is not insured or guaranteed by the Federal Deposit Insurance Corporation or any
other government agency. Although the Money Market Portfolio seeks to preserve the value of your investment at $1.00 per
share, it is possible to lose money by investing in the Portfolio.

PRINCIPAL RISKS
The main risks of investing in the Portfolio are identified below.
• Concentration Risk – Because the Portfolio will invest a significant portion of its assets in securities of companies in the
  banking industry, developments affecting the banking industry will have a disproportionate impact on the Portfolio. These risks
  generally include interest rate risk, credit risk and risks associated with regulatory changes in the banking industry. The
  profitability of banks depends largely on the availability and cost of funds, which can change depending on economic
  conditions.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security or the counterparty to a
  repurchase agreement is unwilling or unable to meet its financial obligations.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline. A low interest
  rate environment poses additional risks to the Portfolio. Low yields on the Portfolio’s holdings may have an adverse impact on
  the Portfolio’s ability to provide a positive yield to its shareholders, pay expenses out of Portfolio assets or, at times, maintain a
  stable $1.00 share price.
• Liquidity Risk – Particular investments may be difficult to purchase or sell at an advantageous time or price, if at all. These
  risks may be magnified during periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.

INVESTMENT OBJECTIVE
The primary investment objective of the Portfolio is to provide as high a level of current income as is consistent with prudent
investment risk.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.35%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                  None
                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.04%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.39%            1 Year         3 Years         5 Years         10 Years
                                                                          $40             $125            $219            $493

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 115.08% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in a diversified portfolio
of investment grade debt securities. Investment grade securities are securities rated “investment grade” by at least one Nationally
Recognized Statistical Rating Organization (e.g., BBB- or higher by Standard & Poor’s or Baa3 or higher by Moody’s), or, if
unrated, determined by the Portfolio’s adviser to be of comparable quality. The Portfolio may invest up to 20% of net assets in
non-investment grade, high yield/high risk bonds (so called “junk bonds”). Also, the Portfolio may invest up to 30% of net assets
in foreign securities, consistent with its investment objective, including (i) government issued foreign debt denominated in a
foreign currency and not publicly traded in the U.S. and (ii) U.S. currency denominated foreign debt. Debt securities may be of
any duration, but under normal market conditions, the Portfolio attempts to maintain an effective duration (the percentage price
change of the Portfolio, stated in years, for a given change in interest rates, and adjusted for prepayments and yield curve shifts
for mortgage based securities) of between zero and three years, and a dollar weighted average maturity of not more than three
years. The Portfolio may invest in mortgage- and asset-backed securities, and may utilize futures and forward contracts to adjust
the Portfolio’s duration and yield curve exposure, to hedge foreign currency exposure or for any other permissible purpose in
keeping with its investment objective.

Northwestern Mutual Series Fund, Inc.                        NMSF–60
                                                                                   Short-Term Bond Portfolio
In selecting securities for the Portfolio, the adviser develops an outlook for interest rates and the economy, analyzes credit and
call risks, and uses other security selection techniques. The adviser uses both a top-down and bottom-up investment approach to
construct the portfolio of investments. The top-down investment approach involves an evaluation by the adviser of the overall
economic environment and its potential impact on the level and direction of interest rates. The adviser then identifies sectors it
believes have the best potential for performance based on economic and business cycles. The bottom-up investment approach
focuses on fundamental research of issuers to identify issuers that appear to have strong relative credit quality, solid balance
sheets, improving company specific fundamentals and free cash flows. The proportion of the Portfolio’s assets committed to
investments in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based on the
adviser’s outlook for the economy, the financial markets and other factors.
The adviser may sell a portfolio security for a variety of reasons, including to secure gains, limit losses, or to redeploy assets into
more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Debt Obligations of Foreign Governments Risk – The issuer of the foreign debt or the governmental authorities that control
  the repayment of such debt may be unable or unwilling to repay principal or interest when due, and the Portfolio may have
  limited recourse in the event of a default. The market prices of debt obligations of governments and their agencies, and the
  Portfolio’s net asset value, may be more volatile than prices of U.S. debt obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar, or,
  in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Investments in
  securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses than investments
  in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established
  legal, political, business and social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Liquidity Risk – Particular fixed income or derivative investments may be difficult to purchase or sell at an advantageous time
  or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended economic downturn.

Short-Term Bond Portfolio
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The primary investment objective of the Portfolio is to provide as high a level of total return as is consistent with prudent
investment risk. A secondary objective is to seek preservation of shareholders’ capital.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                   Example
 (fees paid directly from your investment)               N/A        This Example is intended to help you compare the cost of
                                                                    investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                    mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                    in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                    all of your shares at the end of those periods. The Example
 Management Fee                                         0.30%       also assumes that your investment has a 5% return each year
                                                                    and that the Portfolio’s operating expenses remain the same.

                                                                    Although your actual costs may be higher or lower, based on
 Other Expenses                                         0.00%       these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses              0.30%            1 Year         3 Years         5 Years         10 Years
                                                                          $31             $97             $169            $381

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 112.85% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in a diversified portfolio
of investment grade debt securities with maturities exceeding one year. Investment grade securities are securities rated investment
grade by at least one Nationally Recognized Statistical Rating Organization (e.g., BBB- or higher by Standard & Poor’s or Baa3
or higher by Moody’s), or, if unrated, determined by the Portfolio’s adviser to be of comparable quality. The Portfolio may invest
up to 20% of net assets in non-investment grade, high yield/high risk bonds (so called “junk bonds”). Also, the Portfolio may
invest up to 30% of net assets in foreign securities, consistent with its investment objective, including (i) government issued
foreign debt denominated in a foreign currency and not publicly traded in the U.S. and (ii) U. S. currency denominated foreign
debt. Debt securities may be of any duration, but under normal market conditions, the Portfolio attempts to maintain an effective
duration (the percentage price change of the Portfolio, stated in years, for a given interest rate, and adjusted for prepayments and
yield curve shifts for mortgage based securities) of between three and eight years and a dollar weighted average maturity of
between five and ten years. The Portfolio may invest in mortgage- and asset-backed securities, and may utilize futures and
forward contracts and swap agreements to adjust the Portfolio’s duration and yield curve exposure, to hedge foreign currency
exposure or for any other permissible purpose in keeping with its investment objective. From time to time, the Portfolio may lend
its portfolio securities to brokers, dealers or other financial institutions to seek to achieve income.

current income, including interest and discount accruals, and capital appreciation.

more promising opportunities.

  payments or otherwise comply with the terms of the contract.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar, or,
  in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Investments in
  securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses than investments
  in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. The risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established
  legal, political, business and social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Liquidity Risk – Particular fixed income or derivative investments may be difficult to purchase or sell at an advantageous time
  or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended economic downturn.

• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.
• Securities Lending Risk – Lending portfolio securities to brokers, dealers and financial institutions risks possible loss of
  rights in the collateral should the borrower fail which may cause the Portfolio to lose money.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The Portfolio’s investment objective is to seek maximum total return, consistent with preservation of capital and prudent
investment management.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                 Example
    (fees paid directly from your investment)             N/A        This Example is intended to help you compare the cost of
                                                                     investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                     mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                     in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                     all of your shares at the end of those periods. The Example
    Management Fee                                       0.56%       also assumes that your investment has a 5% return each year
                                                                     and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees                 None
                                                                     Although your actual costs may be higher or lower, based on
    Other Expenses*                                      0.06%       these assumptions your costs would be:

                                                                          $63             $199            $346            $774
  Restated to include estimated interest expenses of 0.01%.
** The operating expenses of the Portfolio reflected in the

Portfolio’s most recent annual report and Financial Highlights do
not include fees and expenses incurred indirectly by the Portfolio
as a result of investments in shares of one or more investment
companies (referred to as “Acquired Fund Fees and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 525.61% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio seeks to achieve its investment objective by investing under normal circumstances at least 80% of its net assets
(plus any borrowings for investment purposes) in a diversified portfolio of fixed income securities that are issued or guaranteed
by the U.S. Government, its agencies or government sponsored enterprises (“U.S. Government Securities”). Assets not invested
in U.S. Government Securities may be invested in other types of non-government related investment grade fixed income
instruments, such as corporate debt securities of U.S. issuers and mortgage- and asset-backed securities, subject to the quality
restrictions described below. The Portfolio may also invest up to 10% of its net assets in preferred stocks.



Northwestern Mutual Series Fund, Inc.                          NMSF–66
                                                Long-Term U.S. Government Bond Portfolio
The Portfolio may also obtain exposure to U.S. Government Securities through the use of futures contracts (including related
options) with respect to such securities, and options on such securities, when the adviser deems it appropriate to do so. The
Portfolio will normally have a minimum average portfolio duration of eight years and, for point of reference, the dollar weighted
average maturity of the Portfolio is expected to be more than ten years.
The Portfolio may invest all of its assets in derivative instruments, such as options, futures contracts or swap agreements, in
municipal bonds or in mortgage- or asset-backed securities, subject to the Portfolio’s objective and the Fund’s policies. The
adviser may invest in derivatives at any time it deems appropriate. It will generally do so when it believes that U.S. Government
Securities are overvalued relative to derivative instruments or to adjust the overall duration of the Portfolio. The potential
leverage created by use of derivatives may cause the Portfolio to be more sensitive to interest rate movements and thus more
volatile than other long-term U.S. government bond funds that do not use derivatives. The Portfolio may purchase or sell
securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Portfolio may,
without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of
purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls). The “total return” sought
by the Portfolio consists of income earned on the Portfolio’s investments, plus capital appreciation, if any, which generally arises
from decreases in interest rates or improving credit fundamentals for a particular sector or security. The Portfolio may engage in
frequent and active trading of portfolio securities to achieve its investment objective, particularly during periods of volatile
market movements.
The Portfolio’s investments in fixed income securities are limited to investment grade U.S. dollar denominated securities of U.S.
issuers that are rated at least A by Moody’s or equivalently rated by S&P or Fitch, or, if unrated, determined by the adviser to be
of comparable quality. If a downgrade in the rating of a security in which the Portfolio is invested causes it to fall outside these
parameters, the adviser will sell the impacted security as soon as reasonably practicable. In addition, the Portfolio may only invest
up to 10% of its total assets in securities rated A by Moody’s or equivalently rated by S&P or Fitch, and may only invest up to
25% of its total assets in securities rated Aa by Moody’s or equivalently rated by S&P or Fitch.
The Portfolio may sell a position when, in the adviser’s opinion, it no longer represents a good value, when a superior risk/return
opportunity exists in a substitute position, or when it no longer fits within the Portfolio’s macroeconomic or structural strategy.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money.
• Counterparty Risk – The Portfolio may sustain a loss in the event the other party(s) in an agreement or a participant to a
  transaction, such as a broker or swap counterparty, defaults on a contract or fails to perform by failing to pay amounts due,
  failing to fulfill delivery conditions, or failing to otherwise comply with the terms of the contract. Counterparty risk is inherent
  in many transactions, including derivatives transactions.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security or the counterparty to a
  derivatives contract is unwilling or unable to meet its financial obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• High Portfolio Turnover Risk – Active and frequent trading may cause higher brokerage expenses and other transaction
  costs, which may adversely affect the Portfolio’s performance.


                                                             NMSF–67                        Northwestern Mutual Series Fund, Inc.
Long-Term U.S. Government Bond Portfolio
• Inflation Risk – Your investment in the Portfolio may not provide enough income to keep pace with inflation.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline. A Portfolio with
  a longer average portfolio duration will be more sensitive to changes in interest rates than a portfolio with a shorter average
  portfolio duration.
• Leverage Risk – Certain transactions, such as reverse repurchase agreements, loans of portfolios securities, when issued,
  delayed delivery or forward commitments transactions, or the use of derivative transactions, may give rise to leverage, causing
  more volatility than if the Portfolio had not been leveraged.
• Liquidity Risk – Particular fixed income or derivative investments may be difficult to purchase or sell at an advantageous time
  or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended economic downturn
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.
• Municipal Securities Risk – The value of municipal securities in which the Portfolio invests may be more sensitive to certain
  adverse conditions than other fixed income securities and the yields of municipal securities may move differently and
  adversely compared to the yields of the overall debt securities markets. Certain municipal securities may be or become highly
  illiquid. Illiquidity may be exacerbated from time to time by market or economic events. Municipal securities may lose their
  tax-exempt status if certain legal requirements are not met, or if federal or state tax laws change. The Portfolio's investments in
  certain municipal securities with principal and interest payments that are made from the revenues of a specific project or
  facility, and not general tax revenues, may have increased risks.
• Short Sale Risk – The risk of entering into short sales, including the potential loss of more money than the actual cost of the
  investment, and the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Portfolio.
• When Issued, Delayed Delivery and Forward Commitment Risk – When issued, delayed delivery purchases and forward
  commitment transactions involve a risk of loss if the value of the securities declines prior to the settlement date. This risk is in
  addition to the risk that the Portfolio’s other assets will decline in value. Therefore, these transactions may result in a form of
  leverage and increase the Portfolio’s overall investment exposure.

varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

   Before you invest, you may want to review the Portfolio’s prospectus, which contains more information about the Portfolio
   and its risks. You can find the Portfolio’s prospectus and other information about the Portfolio online at
   www.nmseriesfund.com. You can also get this information at no cost by calling 1-888-455-2232 or by sending an e-mail
   request to sfprospectus@northwesternmutual.com. The current prospectus and statement of additional information, each

INVESTMENT OBJECTIVE
The Portfolio’s investment objective is to pursue total return using a strategy that seeks to protect against U.S. inflation.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

 Shareholder Fees                                                     Example
 (fees paid directly from your investment)                N/A         This Example is intended to help you compare the cost of
                                                                      investing in the Portfolio with the cost of investing in other
 Annual Portfolio Operating Expenses
                                                                      mutual funds. The Example assumes that you invest $10,000
 (expenses that you pay each year as a percentage
                                                                      in the Portfolio for the time periods indicated and then redeem
 of the value of your investment)
                                                                      all of your shares at the end of those periods. The Example
 Management Fee                                          0.57%        also assumes that your investment has a 5% return each year
                                                                      and that the Portfolio’s operating expenses remain the same.
 Distribution and Service (12b-1) Fees                   None
                                                                      Although your actual costs may be higher or lower, based on
 Other Expenses                                          0.04%        these assumptions your costs would be:
 Total Annual Portfolio Operating Expenses               0.61%            1 Year          3 Years          5 Years        10 Years
                                                                            $62             $195            $340                $762

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 68.09% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio invests substantially all of its assets in investment grade debt securities. To help protect against U.S. inflation, under
normal conditions, the Portfolio will invest over 50% of its net assets (plus any borrowings for investment purposes) in inflation-
linked debt securities. These securities include inflation-linked U.S. Treasury Securities, inflation-linked securities issued by U.S.
government agencies and instrumentalities other than the U.S. Treasury, and inflation-linked securities issued by other entities
such as domestic and foreign corporations and governments. Inflation-linked securities are designed to protect the future
purchasing power of the money invested in them. The Portfolio also may invest in fixed income securities that are not linked to
inflation, including mortgage- and asset-backed securities. The Portfolio invests primarily in investment grade securities, but may
invest up to 10% of its total assets in high yield securities (so called “junk bonds”).
Due to Internal Revenue Code provisions governing insurance product funds, no more than 55% of the Portfolio’s assets may be
invested in securities issued by the same entity. Because the number of inflation-linked debt securities issued by other entities is
limited, at times the Portfolio may have a substantial position in non-inflation-linked securities. To seek to reduce the impact of
this limitation, the adviser may invest in derivative instruments such as options, futures contracts, options on futures contracts,
and swap agreements, provided that such instruments are in keeping with the Portfolio’s investment objective. In addition, the
adviser may use credit default swaps to increase or decrease overall credit exposure. The Portfolio may purchase securities in a
number of different ways to seek higher rates of return.

Northwestern Mutual Series Fund, Inc.                         NMSF–70
                                                                               Inflation Protection Portfolio
The adviser is not limited to a specific weighted average maturity range. However, the adviser monitors the Portfolio’s weighted
average maturity and seeks to adjust it as appropriate, taking into account market conditions, the current inflation rate and other
relevant factors.
The Portfolio may invest up to 20% of its total assets in securities denominated in foreign currencies and may invest beyond this
limit in U.S. dollar denominated securities of foreign issuers. The Portfolio may hedge some or all of its foreign currency to seek
to reduce the risk of loss due to fluctuations in the currency exchange rates, when the adviser deems it to be advantageous.
The Portfolio may sell a security for a variety of reasons, including its assessment of the security’s relative attractiveness in light
of its evaluation of current economic conditions or the risk of inflation, or to manage the Portfolio’s maturity and credit quality
standards.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money.
• Counterparty Risk – The Portfolio may sustain a loss in the event the other party(s) in an agreement or a participant to a
  transaction, such as a broker or swap counterparty, defaults on a contract or fails to perform by failing to pay amounts due,
  failing to fulfill delivery conditions, or failing to otherwise comply with the terms of the contract. Counterparty risk is inherent
  in many transactions, including derivatives transactions.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Debt Obligations of Foreign Governments Risk – The issuer of the foreign debt or the governmental authorities that control
  the repayment of such debt may be unable or unwilling to repay principal or interest when due, and the Portfolio may have
  limited recourse in the event of a default. The market prices of debt obligations of governments and their agencies, and the
  Portfolio’s net asset value, may be more volatile than prices of U.S. debt obligations. In addition, unlike debt instruments
  issued by the U.S. Treasury, inflation-linked bonds issued by corporations or foreign governments do not generally provide
  principal protection, and in a deflationary environment, such bonds may result in the loss of principal.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar, or in the case of hedged positions, that the U.S. dollar will decline in value
  relative to the currency being hedged, and may be less liquid, more volatile, and harder to value than U.S. securities. The
  Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political, business and
  social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Inflation Risk – Your investment in the Portfolio may not provide enough income to keep pace with inflation. To the extent
  that the Portfolio holds investments in non-inflation-linked debt securities, as noted above, that portion of the Portfolio will not
  be automatically protected from inflation.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.

Inflation Protection Portfolio
• Liquidity Risk – Particular fixed income or derivative investments may be difficult to purchase or sell at an advantageous time
  or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 71.62% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio invests at least 80% of net assets (plus any borrowings for investment purposes) in non-investment grade
debt securities. Non-investment grade securities are securities rated below investment grade by at least one Nationally
Recognized Statistical Rating Organization (e.g., BB+ or lower by Standard & Poor’s or Ba1 or lower by Moody’s), or, if
unrated, determined by the Portfolio’s adviser to be of comparable quality.
The Portfolio may invest up to 30% of net assets in foreign securities, consistent with its investment objective, including
(i) foreign securities denominated in a foreign currency and not publicly traded in the U.S. and (ii) U. S. currency denominated
foreign securities, including depositary receipts and depositary shares issued by U.S. banks (American Depositary Receipts) and
U.S. broker-dealers (American Depositary Shares).
The securities in which the Portfolio primarily invests are considered speculative and are sometimes known as “junk bonds.”
These securities tend to offer higher yields than higher rated securities of comparable maturities because the historical financial
condition of the issuers of these securities is usually not as strong as that of other issuers. Some of the fixed income securities in
which the Portfolio invests may be convertible securities.

High Yield Bond Portfolio
The primary investment strategy of the Portfolio is identify, based on industry and credit analysis, and to invest in, industries or
individual companies that are attractively priced or which have stable or improving fundamental financial characteristics relative
to the overall high yield market. The success of this strategy depends on the manager’s analytical and portfolio management
skills. These skills are more important in the selection of high yield/high risk securities than would be the case with a portfolio of
high quality bonds. In selecting securities for the Portfolio, the adviser will consider the ratings assigned by the major rating
agencies, but primary reliance will be placed on the adviser’s evaluation of credit and market risk in relationship to the expected
rate of return.
The adviser may sell a portfolio security for a variety of reasons, such as a change in the adviser’s fundamental view regarding
the prospects of the issuer, a change in industry or sector outlook, or to redeploy assets into more promising opportunities.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money.
• Convertible Securities Risk – Convertible securities can include bonds, notes, debentures, preferred stock or other securities
  which are convertible into common stock. Convertible securities are subject to both the credit and interest rate risks associated
  with fixed income securities and to the stock market risk associated with equity securities. Stock markets are volatile, and the
  price of equity securities can fluctuate based on a company’s financial condition and overall market and economic conditions.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be adversely affected by decreases in
  foreign currency values relative to the U.S. dollar, or in the case of hedged positions, that the U.S. dollar will decline in value
  relative to the currency being hedged, and may be less liquid, more volatile, and harder to value than U.S. securities. The
  Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal, political, business and
  social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Inflation Risk – Your investment in the Portfolio may not provide enough income to keep pace with inflation.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Liquidity Risk – Particular investments may be difficult to purchase or sell at an advantageous time or price, if at all. These
  risks may be magnified during periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. In addition, the broader
market exposure which results from the Index’s 2% issuer cap more closely aligns with the Portfolio’s investment objective and
strategy. Returns are based on past results and are not an indication of future performance. Neither the bar chart nor the table
reflects the fees and expenses separately charged by the variable annuity contract or variable life insurance policy separate
account that invests in the Portfolio and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The Portfolio’s investment objective is to seek maximum total return, consistent with prudent investment management.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                 Example
    (fees paid directly from your investment)             N/A        This Example is intended to help you compare the cost of
                                                                     investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                     mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                     in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                     all of your shares at the end of those periods. The Example
    Management Fee                                       0.79%       also assumes that your investment has a 5% return each year

    Restated to include estimated interest expenses of 0.07%.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 102.10% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Normally, the Portfolio seeks to achieve its investment objective by investing at least 80% of its net assets (plus any borrowings
for investment purposes) in a diversified portfolio of fixed income instruments of varying maturities, which may be represented
by forwards or derivatives such as options, futures contracts or swap agreements. The average portfolio duration of the Portfolio
normally varies within a three- to eight-year time frame based on the Adviser’s forecast for interest rates.
The Portfolio may invest all of its assets in high yield securities subject to a maximum of 10% of its total assets in securities rated
below B by Moody’s or equivalently rated by S&P or Fitch or, if unrated, determined by the Portfolio’s adviser to be of
comparable quality (so called “junk bonds”). The Portfolio may invest, without limitation, in securities denominated in foreign
currencies and U.S. dollar denominated securities of foreign issuers. In addition, the Portfolio may invest without limit in fixed
income securities of issuers that are economically tied to emerging securities markets. The Portfolio may invest in illiquid
securities. The Portfolio may also invest up to 10% of its net assets in preferred stocks.
The Portfolio may invest all of its assets in derivative instruments, such as options, futures contracts or swap agreements, in
municipal bonds, or in mortgage- or asset-backed securities, subject to the Portfolio’s objective and policies. The Portfolio may
purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The

                                                                                 Multi-Sector Bond Portfolio
Portfolio may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a
series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls). The “total
return” sought by the Portfolio consists of income earned on the Portfolio’s investments, plus capital appreciation, if any, which
generally arises from decrease in interest rates or improving credit fundamentals for a particular sector or security. The Portfolio
may engage in frequent and active trading of portfolio securities to achieve its investment objective, particularly during periods of
volatile market movements.
In selecting securities for a Portfolio, the adviser develops an outlook for interest rates, foreign currency exchange rates and the
economy; analyzes credit and call risks, and uses other security selection techniques. The proportion of a Portfolio’s assets
committed to investment in securities with particular characteristics (such as quality, sector, interest rate or maturity) varies based
on the adviser’s outlook for the U.S. and foreign economies, the financial markets and other factors.
The adviser attempts to identify areas of the bond market that are undervalued relative to the rest of the market. The adviser
identifies these areas by grouping bonds into the following sectors: money markets, governments, corporates, mortgages, asset-
backed and international. Sophisticated proprietary software then assists in evaluating sectors and pricing specific securities.
Once investment opportunities are identified, the adviser will shift assets among sectors depending upon changes in relative
valuations and credit spreads.
The Portfolio may sell a position when, in the adviser’s opinion, it no longer represents a good value, when a superior risk/return
opportunity exists in a substitute position, or when it no longer fits within the Portfolio’s macroeconomic or structural strategy.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money.
• Counterparty Risk – The Portfolio may sustain a loss in the event the other party(s) in an agreement or a participant to a
  transaction, such as a broker or swap counterparty, defaults on a contract or fails to perform by failing to pay amounts due,
  failing to fulfill delivery conditions, or failing to otherwise comply with the terms of the contract. Counterparty risk is inherent
  in many transactions, including derivatives transactions.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar, or,
  in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Investments in
  securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses than investments
  in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Investments in emerging markets impose risks different from,
  and greater than, investments in developed markets. Foreign securities may be less liquid, more volatile, and harder to value
  than U.S. securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established legal,
  political, business and social frameworks to support securities markets.

Multi-Sector Bond Portfolio
• High Portfolio Turnover Risk – Active and frequent trading may cause higher brokerage expenses and other transaction
  costs, which may adversely affect the Portfolio’s performance.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Inflation Risk – Your investment in the Portfolio may not provide enough income to keep pace with inflation.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Leverage Risk – Certain transactions, such as reverse repurchase agreements, loans of portfolios securities, inverse floaters,
  structured notes and the use of derivative transactions, may give rise to leverage, causing more volatility than if the Portfolio
  had not been leveraged.
• Liquidity Risk – Particular fixed income or derivative investments may be difficult to purchase or sell at an advantageous time
  or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.
• Municipal Securities Risk – The value of municipal securities in which the Portfolio invests may be more sensitive to certain
  adverse conditions than other fixed income securities and the yields of municipal securities may move differently and
  adversely compared to the yields of the overall debt securities markets. Certain municipal securities may be or become highly
  illiquid. Illiquidity may be exacerbated from time to time by market or economic events. Municipal securities may lose their
  tax-exempt status if certain legal requirements are not met, or if federal or state tax laws change. The Portfolio's investments in
  certain municipal securities with principal and interest payments that are made from the revenues of a specific project or
  facility, and not general tax revenues, may have increased risks.
• Short Sale Risk – The risk of entering into short sales, including the potential loss of more money than the actual cost of the
  investment, and the risk that the third party to the short sale may fail to honor its contract terms, causing a loss to the Portfolio.
• When Issued, Delayed Delivery and Forward Commitment Risk – When issued, delayed delivery purchases and forward
  commitment transactions involve a risk of loss if the value of the securities declines prior to the settlement date. This risk is in
  addition to the risk that the Portfolio’s other assets will decline in value. Therefore, these transactions may result in a form of
  leverage and increase the Portfolio’s overall investment expense.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The Portfolio’s investment objective is total return.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    (fees paid directly from your investment)             N/A         This Example is intended to help you compare the cost of
                                                                      investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                      mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                      in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)

the current fiscal year.
** Acquired Fund Fees and Expenses are the expenses

indirectly incurred by the Portfolio as a result of its
investments in investment companies and other pooled
investment vehicles as well as the expenses of investing in the
Portfolio’s wholly owned Cayman Islands subsidiary fund.
*** The Portfolio’s investment adviser has entered into a

written agreement to waive its management fee in an amount
equal to the management fee paid to it by the Portfolio’s
wholly owned Cayman Islands subsidiary fund. This waiver
will remain in effect for the life of the Portfolio, as long as the
Portfolio remains invested in the subsidiary fund.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio

Northwestern Mutual Series Fund, Inc.                            NMSF–80
                                                         Commodities Return Strategy Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. Because the Portfolio is new and has no shares
outstanding, it does not have a portfolio turnover rate at this time.

PRINCIPAL INVESTMENT STRATEGIES
The Portfolio is designed to achieve positive total return relative to the performance of the Dow Jones-UBS Commodity Index
Total Return (“DJ-UBS Index”). The DJ-UBS Index is a broadly diversified futures index composed of futures contracts on 19
physical commodities. The DJ- UBS Index is rebalanced as of the beginning of each calendar year so that as of that time no single
commodity constitutes more than 15% or less than 2% of the Index, and each related group of commodities represented in the
Index is limited to 33%. However, following this rebalancing and for the remainder of the calendar year these percentages may
change so that a single commodity may constitute a lesser or greater percentage of the Index and different sectors may represent
different proportions of the Index.
The Portfolio, which is actively managed, intends to invest primarily, either directly or indirectly through a wholly-owned
subsidiary, in commodity index-linked and commodity-linked derivative instruments linked to the DJ-UBS Index, other
derivatives, cash and fixed income securities. While the Portfolio seeks to achieve positive total return relative to the DJ-UBS
Index, it is not an index fund and there can be no guarantee that this performance will be achieved. The Portfolio does not intend
to invest in physical commodities.
The Portfolio intends to gain its principal exposure to the commodities markets by investing up to 25% of its total assets in the
NMSF Cayman Commodity Fund, Ltd., a wholly owned subsidiary of the Portfolio organized under the laws of the Cayman
Islands (“Subsidiary”). To a lesser extent, the Portfolio may gain exposure to commodities markets by investing directly in
commodity-linked derivatives and other derivative instruments, including swap agreements. The Portfolio will limit its direct
investments in commodity-linked swap agreements or certain other commodity-linked derivatives such that the income derived
from those instruments is limited to a maximum of 10% of the Portfolio’s annual gross income.
Investing in the Subsidiary allows the Portfolio to achieve greater exposure to the commodities markets than would otherwise be
possible because of U.S. tax law requirements. The Subsidiary has the same investment objective as the Portfolio and its assets
are managed by the same investment adviser and sub-adviser. However, unlike the Portfolio, the Subsidiary may invest without
limitation in commodity index-linked and commodity-linked derivative instruments and other derivatives such as swaps and
futures that provide exposure to the performance of the commodities markets. The use of these instruments may give rise to
leverage, particularly at the Subsidiary level. The Subsidiary also may invest in fixed income instruments. Although the
Subsidiary is otherwise subject to the same fundamental, non-fundamental and certain other investment restrictions as the
Portfolio, the investment programs of the Portfolio and the Subsidiary are not identical. Certain derivative instruments in which
the Portfolio and the Subsidiary invest may be illiquid.
For the portion of the Portfolio’s assets not invested in commodity-linked derivatives, the Portfolio will invest in fixed income
securities. The Portfolio emphasizes investment-grade fixed income securities and its fixed income portfolio will normally have
an average duration of one year or less. The Portfolio may invest without limit in U.S. dollar-denominated foreign securities and
may invest up to 30% of its assets in non-U.S. dollar-denominated securities.
The Portfolio is classified as a “non-diversified fund” under the Investment Company Act of 1940, as amended (“1940 Act”)
which means that a relatively high percentage of the Portfolio’s assets may be invested in a limited number of issuers.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
The Portfolio is not intended to serve as a core holding in an investor’s investment program but instead should only form a small
part of a diversified portfolio. At any time, the risk of loss associated with a particular investment held by the Portfolio may be
significantly higher than 50% of the value of the investment. Investors considering an investment in the Portfolio should be
willing to accept significant volatility in the Portfolio’s performance, particularly over shorter time periods.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. While the primary driver of the Portfolio’s returns is
  expected to be the change in value of the DJ-UBS Index, the Portfolio is not an index fund.
• Commodity Risk – The Portfolio’s investment in commodity-linked derivative instruments may subject the Portfolio to
  greater volatility than investments in traditional securities, particularly if the instruments involve leverage. The value of the
  DJ-UBS Index, and therefore the value of any derivative instruments linked to that Index, may be affected by changes in

                                                             NMSF–81                       Northwestern Mutual Series Fund, Inc.
Commodities Return Strategy Portfolio
  overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or
  commodity, such as drought, floods, weather, livestock disease, embargoes, tariffs and international economic, political and
  regulatory developments.
• Correlation Risk – Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or
  index. For example, changes in the value of a hedging instrument may not match those of the investment being hedged. Related
  to other types of assets, the prices of commodity-linked instruments may move in different directions than investments in
  traditional equity and debt securities. However, there can be no guarantee that the Portfolio’s commodity-linked investments
  would not be correlated with traditional financial assets under any particular market conditions. In addition, the performance of
  the Portfolio’s commodity-linked instruments may diverge from the performance of the DJ-UBS Index, perhaps materially.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Counterparty Risk – The Portfolio may sustain a loss in the event the other party(s) in an agreement or a participant to a
  transaction, such as a broker or swap counterparty, defaults on a contract or fails to perform by failing to pay amounts due,
  failing to fulfill delivery conditions, or failing to otherwise comply with the terms of the contract. Counterparty risk is inherent
  in many transactions, including derivatives transactions.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio typically uses derivatives as a substitute for taking a position in the underlying asset and/or as part of a
  strategy designed to reduce exposure to other risks, such as interest rate or currency risk. The Portfolio may also use
  derivatives for leverage, which could result in greater volatility for the Portfolio, particularly during periods of market decline,
  and could magnify losses. Investments in derivatives may not have the intended effects and may result in losses for the
  Portfolio that may not have otherwise occurred or missed opportunities for the Portfolio. The Portfolio’s use of derivative
  instruments, particularly commodity-linked derivatives, involves risks different from, or possibly greater than, the risks
  associated with investing directly in securities and other traditional investments. Derivatives also involve commodity,
  counterparty, correlation, management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Investing in derivatives could cause the Portfolio to lose more than the principal amount invested.
• Exposure Risk – The risk associated with investments (such as derivatives) or practices that increase the amount of money the
  portfolio could gain or lose on an investment. Related to hedging, exposure risk could multiply losses generated by a derivative
  or practice used for hedging purposes. Such losses should be substantially offset by gains on the hedged investment. However,
  while hedging can reduce or eliminate losses, it can also reduce or eliminate gains. For speculative positions, to the extent that
  a derivative or practice is not used as a hedge, the Portfolio is directly exposed to its risks. Gains or losses from speculative
  positions in a derivative may be much greater than the derivative’s original cost.
• Focus Risk – The Portfolio will be exposed to the performance of commodities in the DJ-UBS Index, which may from time to
  time have a small number of commodity sectors (e.g., energy, metals or agricultural) representing a large portion of the Index.
  As a result, the Portfolio may be subject to greater volatility than if the Index were more broadly diversified among commodity
  sectors.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar, or,
  in the case of hedged positions, that the U.S. dollar will decline in value relative to the currency being hedged. Investments in
  securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses than investments
  in U.S. dollar denominated securities. Although the Portfolio may seek to reduce currency risk by hedging part or all of its
  exposure to various foreign currencies, it is not required to do so.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Investments in emerging markets impose risks different from,
  and greater than, investments in developed markets. Foreign securities may be less liquid, more volatile, and harder to value
  than U.S. securities.
• Interest Rate Risk – The value of the Portfolio’s fixed income or derivative investments may decline because of a change in
  market interest rates.

                                                          Commodities Return Strategy Portfolio
• Leverage Risk – Certain transactions utilized by the Portfolio and the Subsidiary, such as the use of derivative instruments,
  may give rise to leverage, causing more volatility than if the Portfolio had not been leveraged. The use of leverage may cause
  the Portfolio or the Subsidiary to liquidate positions when it may not be advantageous to do so to satisfy obligations. The use of
  leveraged commodity-linked derivatives creates an opportunity for increased return but, at the same time, creates the
  possibility for greater loss (including the likelihood of greater volatility of the Portfolio’s net asset value), and there can be no
  assurance that the Portfolio’s use of leverage will be successful.
• Liquidity Risk – Particular derivative investments such as commodity-linked swaps may be difficult to purchase or sell at an
  advantageous time or price, if at all. These risks may be magnified during periods of economic turmoil or in an extended
  economic downturn.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Non-Diversification Risk – The Portfolio is classified as a non-diversified fund and is permitted to invest a greater proportion
  of its assets in the securities of a smaller number of issuers. As a result, the Portfolio’s performance may be more volatile than
  the performance of a more diversified fund.
• Subsidiary Risk – By investing in the Subsidiary, the Portfolio is indirectly exposed to the risks associated with the
  Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are
  permitted to be held by the Portfolio and are subject to the same risks that apply to similar investments if held directly by the
  Portfolio. There can be no assurance that the investment objective of the Subsidiary will be achieved. The Subsidiary is not
  registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. However, the Portfolio wholly
  owns and controls the Subsidiary, and the Portfolio and the Subsidiary are both managed by the same investment adviser and
  sub-adviser, making it unlikely that the Subsidiary will take action contrary to the interests of the Portfolio and its shareholders.
  Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Portfolio and/or the
  Subsidiary to operate as it does currently and could adversely affect the Portfolio.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is to realize as high a level of total return as is consistent with prudent investment risk,
through income and capital appreciation.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                 Example
    (fees paid directly from your investment)             N/A        This Example is intended to help you compare the cost of
                                                                     investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                     mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage of
                                                                     in the Portfolio for the time periods indicated and then redeem
    the value of your investment)
                                                                     all of your shares at the end of those periods. The Example
    Management Fee                                        0.30%      also assumes that your investment has a 5% return each year
                                                                     and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees                 None
                                                                     Although your actual costs may be higher or lower, based on
    Other Expenses                                        0.00%      these assumptions your costs would be:
    Acquired Fund Fees and Expenses                       0.03%          1 Year          3 Years         5 Years         10 Years
    Total Annual Portfolio Operating Expenses*            0.33%            $34             $106            $185            $418

* The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares of one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 81.33% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES
Investing in the stock, bond and money market sectors, the Portfolio attempts to capitalize on the variation in return potential
produced by the interaction of changing financial markets and economic conditions while maintaining a balance over time
between investment opportunities and their associated potential risks by following a flexible policy of allocating assets across the
three market sectors.




Northwestern Mutual Series Fund, Inc.                         NMSF–84
                                                                                                 Balanced Portfolio
The Portfolio is tactically and strategically managed to capitalize on changing financial markets and economic conditions
following a flexible policy for allocating assets according to the following benchmarks:
            Equity Securities                    Fixed Income or Debt Securities                      Cash Equivalents
                 35 – 55%                                     40 – 60%                                     0 – 20%

These benchmarks are not minimum and maximum limits and the adviser, in pursuit of total return, may invest a greater or lesser
percentage in any component.
Equity investments will be actively managed and may consist of small, mid and large capitalization companies and foreign stocks
based on the adviser’s economic and market outlook, and its perceived opportunities in each class. The Portfolio will employ both
“growth” and “value” styles in managing the equity sector. Debt securities will generally consist primarily of investment grade
debt securities with maturities exceeding one year, though the Portfolio may invest up to 20% of the Portfolio’s total net assets in
non-investment grade debt securities (often called “junk bonds”). The cash equivalent portion of the Portfolio may include, but is
not limited to, debt securities issued or guaranteed by the U.S. government or its agencies or instrumentalities, commercial paper,
banker’s acceptances, certificates of deposit and time deposits.
Up to 50% of the Portfolio’s net assets may be invested in foreign securities, up to a maximum of 25% in foreign stocks and 25%
in foreign bonds. The adviser may overweight or underweight the sector, industry or country exposure of the international equity
portion of the Portfolio (versus applicable benchmarks) based on the adviser’s assessment of the relative attractiveness of such
sectors, industries and countries. When the adviser deems it to be more efficient or advantageous, the adviser may utilize options,
futures, forwards, swap agreements and exchange-traded funds to gain exposure to certain markets, sectors or regions as
alternatives to direct investments, to adjust the Portfolio for the adviser’s view on style or term structure and duration, to provide
increased flexibility in asset allocation or to hedge foreign currency exposure. The Portfolio may also invest in mortgage- and
asset-backed securities. From time to time, the Portfolio may lend its portfolio securities to brokers, dealers or other financial
institutions to seek to achieve income.
The Portfolio is designed primarily for investors who want their investment allocated across major asset classes while pursuing
the growth potential of stocks, but who also want the income potential of bonds. The investor should be willing to accept
fluctuation in share prices that are typical for a portfolio that holds stock investments.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform other mutual funds or lose money. Also, an actively managed Portfolio using a particular
  style of investing, such as growth or value or a combination of both, may underperform when the market does not favor the
  particular style used by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market
  conditions and investor sentiment.
• Asset Allocation Risk – This Portfolio allocates its investments between equity and fixed income securities, and among
  various segments of markets, based upon judgments made by the adviser. The Portfolio could miss attractive investment
  opportunities by underweighting markets or sectors where there are significant returns, and could lose value by overweighting
  markets where there are significant declines, or may not correctly predict the times to shift assets from one type of investment
  to another.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.

                                                             NMSF–85                        Northwestern Mutual Series Fund, Inc.
Balanced Portfolio
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar.
  Investments in securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses
  than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established
  legal, political, business and social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.
• Securities Lending Risk – Lending portfolio securities to brokers, dealers and financial institutions risks possible loss of
  rights in the collateral should the borrower fail which may cause the Portfolio to lose money.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

INVESTMENT OBJECTIVE
The investment objective of the Portfolio is to realize as high a level of total return as is consistent with reasonable investment risk.

FEES AND EXPENSES OF THE PORTFOLIO
The table below describes the fees and expenses that you may pay when you buy and hold interests in a separate account that
invests in shares of the Portfolio as a result of your purchase of a variable annuity contract or variable life insurance policy. The
fees and expenses shown in the table and Example do not reflect fees and expenses separately charged by variable annuity
contracts or variable life insurance policies. If the fees and expenses separately charged by variable annuity contracts and variable
life insurance policies were included, the fees and expenses shown in the table and the Example would be higher.

    Shareholder Fees                                                   Example
    (fees paid directly from your investment)             N/A          This Example is intended to help you compare the cost of
                                                                       investing in the Portfolio with the cost of investing in other
    Annual Portfolio Operating Expenses
                                                                       mutual funds. The Example assumes that you invest $10,000
    (expenses that you pay each year as a percentage
                                                                       in the Portfolio for the time periods indicated and then redeem
    of the value of your investment)
                                                                       all of your shares at the end of those periods. The Example
    Management Fee                                       0.54%         also assumes that your investment has a 5% return each year
                                                                       and that the Portfolio’s operating expenses remain the same.
    Distribution and Service (12b-1) Fees                None
                                                                       Although your actual costs may be higher or lower, based on
    Other Expenses                                       0.04%         these assumptions your costs would be:

    Fee Waiver*, **                                      0.56%

*  The operating expenses of the Portfolio reflected in the
Portfolio’s most recent annual report and Financial Highlights
do not include fees and expenses incurred indirectly by the
Portfolio as a result of investments in shares in one or more
investment companies (referred to as “Acquired Fund Fees
and Expenses”).
** The Portfolio’s investment adviser has entered into a written

agreement to waive a portion of its management fee such that
its management fee is 0.55% on the Portfolio’s first $100
million of assets and 0.45% on assets from $100 million to
$250 million. This fee waiver agreement may be terminated
by the adviser at any time after April 30, 2012.

Portfolio Turnover
The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio
Operating Expenses or in the Example, affect the Portfolio’s performance. During the most recent fiscal year, the Portfolio’s
portfolio turnover rate was 73.04% of the average value of its portfolio.

Northwestern Mutual Series Fund, Inc.                           NMSF–88
                                                                                   Asset Allocation Portfolio
PRINCIPAL INVESTMENT STRATEGIES
Investing in the stock, bond and money market sectors, the Portfolio attempts to capitalize on the variation in return potential
produced by the interaction of changing financial markets and economic conditions while maintaining a balance over time
between investment opportunities and their associated potential risks by following a flexible policy of allocating assets across the
three market sectors.
The Portfolio is tactically and strategically managed to capitalize on changing financial markets and economic conditions
following a flexible policy for allocating assets according to the following benchmarks:
            Equity Securities                   Fixed Income or Debt Securities                      Cash Equivalents
                 55 – 75%                                    25 – 45%                                     0 – 15%

These benchmarks are not minimum and maximum limits and the adviser, in pursuit of total return, may invest a greater or lesser
percentage in any component.
Equity investments will be actively managed and may consist of small, mid and large capitalization companies and foreign stocks
based on the adviser’s economic and market outlook, and its perceived opportunities in each class. The Portfolio will employ
either “growth” or “value”, or both, styles in managing the equity sector. Debt securities will generally consist primarily of
investment grade debt securities with maturities exceeding one year, though the Portfolio may invest up to 20% of the Portfolio’s
total net assets in non-investment grade debt securities (often called “junk bonds”) . The cash equivalent portion of the Portfolio
may include, but is not limited to, debt securities issued or guaranteed by the U.S. government or its agencies or instrumentalities,
commercial paper, banker’s acceptances, certificates of deposit and time deposits.
The Portfolio may invest up to 50% of net assets foreign securities. The adviser may overweight or underweight the sector,
industry or country exposure of the international equity portion of the Portfolio (versus applicable benchmarks) based on the
adviser’s assessment of the relative attractiveness of such sectors, industries and countries. When the adviser deems it to be more
efficient or advantageous, the adviser may utilize options, futures, forwards, swap agreements and exchange-traded funds to gain
exposure to certain markets, sectors or regions as alternatives to direct investments, to adjust the Portfolio for the adviser’s view
on style or term structure and duration, to provide increased flexibility in asset allocation or to hedge foreign currency exposure.
The Portfolio may also invest in mortgage- and asset-backed securities.
The Portfolio is designed primarily for investors who want their investment allocated across major asset classes while pursuing
the growth potential of stocks with a smaller allocation to bonds. The investor should be willing to accept fluctuation in share
prices that are typical for a portfolio that holds stock investments.

PRINCIPAL RISKS
Portfolio shares will rise and fall in value and there is a risk you could lose money by investing in the Portfolio. There can be no
assurance that the Portfolio will achieve its objective. The main risks of investing in this Portfolio are identified below.
• Active Management Risk – The adviser’s investment strategies and techniques may not perform as expected which could
  cause the Portfolio to underperform or lose money. Also, an actively managed Portfolio using a particular style of investing,
  such as growth or value or a combination of both, may underperform when the market does not favor the particular style used
  by the Portfolio. Different investment styles tend to shift in and out of favor, depending on market conditions and investor
  sentiment.
• Asset Allocation Risk – This Portfolio allocates its investments between equity and fixed income securities, and among
  various segments of markets, based upon judgments made by the adviser. The Portfolio could miss attractive investment
  opportunities by underweighting markets or sectors where there are significant returns, and could lose value by overweighting
  markets where there are significant declines, or may not correctly predict the times to shift assets from one type of investment
  to another.
• Credit Risk – The Portfolio could lose money if the issuer or guarantor of a fixed income security is unwilling or unable to
  meet its financial obligations.
• Derivatives Risk – The value of a derivative generally depends upon, or is derived from, an underlying asset, reference rate or
  index. The Portfolio’s use of derivatives involves risks different from, or possibly greater than, the risks associated with
  investing directly in securities or other traditional investments. Investments in derivatives may not have the intended effects
  and may result in losses for the Portfolio that may not otherwise have occurred or missed opportunities for the Portfolio.
  Certain derivatives involve leverage, which could cause the Portfolio to lose more than the principal amount invested.

                                                             NMSF–89                        Northwestern Mutual Series Fund, Inc.
Asset Allocation Portfolio
  Derivatives could involve management, credit, interest rate, liquidity and market risks, and the risks of mispricing or improper
  valuation. Changes in the value of the derivative may not correlate as intended with the underlying asset, rate or index. In
  addition, the Portfolio could sustain a loss in the event the counterparty to a derivatives transaction fails to make the required
  payments or otherwise comply with the terms of the contract.
• Equity Securities Risk – The value of equity securities, such as common and preferred stocks, could decline if the financial
  condition of the companies the Portfolio is invested in declines or if overall market and economic conditions deteriorate.
  Equity securities generally have greater price volatility than fixed income securities. Investments in rights and warrants may be
  more volatile than the underlying investments in stocks.
• Exchange Traded Funds Risk – Investing in exchange traded funds (ETFs) may expose the Portfolio to greater risk of loss
  and price fluctuation than investing directly in a comparable portfolio of stocks comprising the index due to lack of liquidity,
  the additional expenses incurred as a shareholder in another investment company, and tracking error.
• Foreign Currency Risk – The risk that foreign (non-U.S. dollar) currency denominated securities, or derivatives that provide
  exposure to foreign currencies, may be adversely affected by decreases in foreign currency values relative to the U.S. dollar.
  Investments in securities subject to foreign currency risk may have more rapid and extreme changes in value or more losses
  than investments in U.S. dollar denominated securities.
• Foreign Investing Risk – Investing in foreign securities may subject the Portfolio to more rapid and extreme changes in value
  or more losses than a fund that invests exclusively in U.S. securities. This risk is due to potentially smaller markets, differing
  reporting, accounting and auditing standards, and nationalization, expropriation or confiscatory taxation, currency blockage,
  political and economic conditions, or diplomatic developments. Foreign securities may be less liquid, more volatile, and harder
  to value than U.S. securities. The Portfolio’s investments in emerging markets heighten these risks due to a lack of established
  legal, political, business and social frameworks to support securities markets.
• High Yield Debt Risk – High yield debt securities in which the Portfolio invests have greater interest rate and credit risk,
  maybe more difficult to sell or sell at a reasonable price, and have greater risk of loss than higher rated securities.
• Interest Rate Risk – Prices of fixed income instruments generally rise and fall in response to changes in market interest rates.
  In a rising interest rate environment, the value of the Portfolio’s fixed income investments is likely to decline.
• Large Cap Company Risk – Investing in large cap stocks could cause the Portfolio to underperform in markets favoring
  faster growing companies. Large cap stocks tend to be more mature with fewer opportunities to grow and may not have the
  same growth potential as stocks with smaller capitalizations.
• Market Risk – The risk that the market price of securities owned by the Portfolio may go up or down, sometimes rapidly or
  unpredictably, due to factors affecting securities markets generally or particular industries.
• Mortgage- and Asset-Backed Securities Risk – The risks of investing in mortgage-related and other asset-backed securities,
  including interest rate risk, credit risk, liquidity risk, extension risk and prepayment risk.
• Small and Mid Cap Company Risk – Investing in small and mid cap stocks may cause greater risk of loss and price
  fluctuation than investing in stocks of larger cap companies due to a more limited track record, narrower product markets, more
  limited resources and less liquid trading markets. These stocks may be more volatile and more difficult to buy and sell than
  stocks with larger capitalizations.

PERFORMANCE
The following bar chart illustrates the risks of investing in the Portfolio by showing how the performance of the Portfolio has
varied from year to year. The table to the right of the bar chart shows the Portfolio’s average annual total return over certain time
periods and compares the Portfolio’s returns with the returns of certain market indices and peer groups. Returns are based on past
results and are not an indication of future performance. Neither the bar chart nor the table reflects the fees and expenses
separately charged by the variable annuity contract or variable life insurance policy separate account that invests in the Portfolio
and returns would be lower if those fees and expenses were reflected.

GOAL
The Fund seeks long-term growth of capital by invesing primarily in securities of companies that meet the Fund’s financial
criteria and social policy.

FEES AND EXPENSES
These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. These tables do not
reflect any expenses or charges that are, or may be, imposed under a variable annuity or variable life insurance separate

applicable variable contract prospectus summary or disclosure statement, or if you purchased shares through a qualified plan,
please consult the plan administrator.

Neuberger Berman Management LLC (“NBM”) has contractually undertaken to limit the Fund’s expenses through December 31, 2014 by waiving
fees and/or reimbursing certain expenses of the Fund so that its total operating expenses (including the compensation of NBM and excluding
taxes, interest, extraordinary expenses, brokerage commissions and transaction costs), in the aggregate, are limited to 1.30% per annum of the
Fund’s average daily net asset value. These fee waivers and/or expense reimbursement are subject to recoupment by NBM within three years.


PORTFOLIO TURNOVER
The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A
higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held
in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s
performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its
portfolio.

S O C I A L LY R E S P O N S I V E P O RT F O L I O                                                                  May 1, 2011




PRINCIPAL INVESTMENT STRATEGIES
To pursue its goal, the Fund invests mainly in common stocks of mid- to large-capitalization companies that meet the Fund’s
social policy. The Fund seeks to reduce risk by investing across many different industries.

The Portfolio Managers employ a research driven and valuation sensitive approach to stock selection with a long-term
perspective. They seek to identify stocks in well-positioned businesses that they believe are undervalued in the market. They
look for solid balance sheets, strong management teams with a track record of success, good cash flow and the prospect for
above average earnings growth. Among companies that meet these criteria, the Portfolio Managers look for those that show
leadership in environmental concerns, and progressive workplace practices including diversity and community relations.

The Portfolio Managers typically also look at a company’s record in public health and the nature of its products. The Portfolio
Managers judge firms on their corporate citizenship overall, considering their accomplishments as well as their goals. While
these judgments are inevitably subjective, the Fund endeavors to avoid companies that derive revenue from gambling or the
production of alcohol, tobacco, weapons or nuclear power. The Fund also does not invest in any company that derives its total
revenue primarily from non-consumer sales to the military.

The Portfolio Managers follow a disciplined selling strategy and may sell a stock when it reaches a target price, when the
company’s business fails to perform as expected, or when other opportunities appear more attractive.

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

The Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity
securities selected in accordance with its social policy. The Fund will not alter this policy without providing shareholders at
least 60 days’ notice. In practice, the Portfolio Managers’ current intention is to hold only equity securities selected in
accordance with the Fund’s social investing policies. This test is applied at the time the Fund invests; later percentage changes
caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

PRINCIPAL INVESTMENT RISKS
Most of the Fund’s performance depends on what happens in the stock market. The market’s behavior is unpredictable,
particularly in the short term. A company’s stock can also be affected by the company’s financial condition. There can be no
guarantee that the Fund will achieve its goal.

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance
Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose
money by investing in the Fund.

The following factors can significantly affect the Fund’s performance:
Stock Market Volatility. Stock markets are volatile and can decline significantly in response to adverse issuer, political,
regulatory, market or economic developments. To the extent that the Fund sells stocks before they reach their market peak, it
may miss out on opportunities for higher performance.

Socially Responsive Investing Risk. The Fund’s social policy could cause it to underperform similar funds without a social
policy since undervalued stocks that do not meet the social criteria could outperform those that do, economic or political
changes could make certain companies less attractive for investment and the social policy could cause the Fund to sell or avoid
stocks that subsequently perform well.

Market Capitalization Risk. Mid-cap stocks tend to be more volatile than large-cap stocks and are usually more sensitive to
economic, political, regulatory and market factors. At any given time, one or both groups of stocks may be out of favor with
investors.

Issuer-Specific Risk. The value of an individual security or particular type of security can be more volatile than the market as
a whole and can perform differently from the value of the market as a whole.

S O C I A L LY R E S P O N S I V E P O RT F O L I O                                                                   May 1, 2011




Value Investing Risk. With a valuation sensitive approach, there is the risk that stocks may remain undervalued during a given
period, because value stocks, as a category, lose favor with investors, or because of a failure to anticipate which stocks or
industries would benefit from changing market or economic conditions.

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks
include exposure to less developed or less efficient trading markets; social, political or economic instability; fluctuations in
foreign currencies; nationalization or expropriation of assets; settlement, custodial or other operational risks; and less
stringent auditing and legal standards. As a result, foreign securities can fluctuate more widely in price and may also be less
liquid than comparable U.S. securities. World markets may all react in similar fashion to important economic or political
developments. In addition, foreign markets can perform differently than the U.S. market. Following the market turmoil of
2008-2009, some national economies continue to show instability, which may in turn affect their international trading
partners.

Currency Risk. Currency fluctuations could erase investment gains or add to investment losses.

Arbitrage Risk. Investing in foreign stocks or thinly-traded securities may involve a greater risk for excessive trading due to
potential arbitrage opportunities. For example, to the extent that the Fund’s net asset value does not immediately reflect
changes in market conditions or the true market value of these securities, an investor may seek to benefit from the pricing
differences caused by this delay.

Recent Market Conditions. Recent events in the U.S. and global economies have resulted, and may continue to result, in an
usually high degree of volatility in the financial markets, both domestic and foreign and in the net asset values of many mutual
funds, including to some extent the Fund. Because the situation is unprecedented and widespread, it may be unusually
difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration
of these market events. The severity or duration of these conditions may also be affected by policy changes made by
governments or quasi-governmental organizations.

TAX INFORMATION
Distributions made by the Fund to a variable annuity or variable life insurance separate account or a qualified pension or
retirement plan, and exchanges and redemptions of Fund shares made by a separate account or qualified plan ordinarily do
not cause the corresponding contract holder or plan participant to recognize income or gain for federal income tax purposes.
Please see your variable contract prospectus or the governing documents of your qualified plan for information regarding the
federal income tax treatment of the distributions to separate accounts or qualified plans and the holders of the contracts or
plan participants.

PAYMENTS TO FINANCIAL INTERMEDIARIES
The Fund and NBM and/or its affiliates may pay insurance companies or their affiliates, qualified plan administrators, broker-
dealers or other financial intermediaries, for services they provide respecting the Fund to current and prospective variable
contract owners and qualified plan participants who choose the Fund as an investment option. These payments may be made
to the intermediaries to render services to variable contract owners and qualified plan participants, and may also provide
incentive for the intermediaries to recommend the Fund’s shares or make them available to current or prospective variable

Investment Objective (Non-Fundamental)
       The Fund seeks to provide long term capital growth.

Fees and Expenses of the Fund
     The following tables describe the fees and expenses that you may pay if you buy and hold Shares of the Fund. The
fees and expenses shown in this section do not reflect any Insurance Company Separate Account or Policy charges. Those
charges, if included, would have increased overall fees and expenses. Please refer to your account or policy documents
for a description of those fees and expenses. Please see the Expense Notes section of the Fund’s Prospectus for further
information regarding expenses of the Fund.

Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same. This example does not reflect any Insurance Company Separate Account or Policy
charges. If it did, the costs shown would have been higher. Although your actual costs may be higher or lower, under
these assumptions your costs would be:

1 Year                3 Years                5 Years                10 Years
 $91                   $284                   $493                  $1,097




                                                                                              1

                                                                                         RIF-1
Portfolio Turnover
     The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 105% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
      The Fund invests primarily in common stocks of medium and large capitalization U.S. companies. The Fund may
also invest in securities of non-U.S. issuers, and typically does so by purchasing American Depositary Receipts (“ADRs”)
or Global Depositary Receipts (“GDRs”). The Fund has a non-fundamental policy to invest, under normal circumstances,
at least 80% of the value of its net assets in equity securities. The Fund employs a multi-style (growth, value and
market-oriented) and multi-manager approach whereby portions of the Fund are allocated to different money managers
who employ distinct investment styles. Fund assets not allocated to money managers are managed by Russell Investment
Management Company (“RIMCo”). RIMCo may employ a “select holdings” strategy designed to increase the Fund’s
exposure to stocks that are viewed as attractive by multiple money managers. The Fund intends to be fully invested at all
times by exposing its cash reserves to the performance of appropriate markets by purchasing equity securities and/or
derivatives, which typically include index futures contracts. Please refer to the “Investment Objective and Investment
Strategies” section in the Fund’s Prospectus for further information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies. The “select holdings” strategy amplifies security selection risk and potential underperformance.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions.
    • Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
      transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
      failing to fulfill the obligations of the contract or transaction.
    • American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
      currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
      associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
      changes in the exchange rates of foreign currencies.
    • Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
      counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
      risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
      derivative may not correlate exactly with the change in the value of the underlying asset, rate or index.
    • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
      in valuing portfolio instruments.
    • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
      adversely affect the value of a security.
    • Large Redemptions. The Fund is used as an investment for certain funds of funds and in asset allocation programs
      and may have a large percentage of its Shares owned by such funds or held in such programs. Large redemption
      activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to
      meet redemptions.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund
varies from year to year. The highest and lowest returns for a full quarter during the periods shown in the bar chart are
set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance Company
Separate Account or Policy charges. Those charges, if included, would have reduced the performance results shown in this
section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with the index returns that measure broad market
performance. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not include fair
valuation adjustments which may be included in fund returns.
      Past performance is no indication of future results.

Management

Investment Adviser
     The Fund’s investment adviser is RIMCo. Unlike most investment companies that have a single organization that
acts as investment adviser, the Fund divides responsibility for investment advice between RIMCo and a number of
unaffiliated money managers. The money managers for the Fund are:
      •   BlackRock Capital Management, Inc.                                                  •   Institutional Capital LLC
      •   Columbus Circle Investors                                                           •   Jacobs Levy Equity Management, Inc.
      •   DePrince, Race & Zollo, Inc.                                                        •   Montag & Caldwell, LLC
      •   First Eagle Investment Management, LLC                                              •   Suffolk Capital Management, LLC

Portfolio Manager
   Stephen W. Skatrud has primary responsibility for the management of the Fund. Mr. Skatrud has been a Portfolio
Manager since December 2001.
     Brian C. Mock has primary responsibility for the management of the portion of the Fund allocated to the select
holdings strategy. Mr. Mock has been a Portfolio Manager since April 2005.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

Portfolio Turnover
     The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 107% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
      The Fund invests primarily in common stocks of small and medium capitalization U.S. companies. The Fund may
also invest in securities of non-U.S. issuers, and typically does so by purchasing American Depositary Receipts (“ADRs”)
or Global Depositary Receipts (“GDRs”). The Fund has a non-fundamental policy to invest, under normal circumstances,
at least 80% of the value of its net assets in equity securities. The Fund may invest a portion of its assets in securities of
companies, known as real estate investment trusts (“REITs”), that own and/or manage properties. The Fund employs a
multi-style (growth, value and market-oriented) and multi-manager approach whereby portions of the Fund are allocated
to different money managers who employ distinct investment styles. Fund assets not allocated to money managers are
managed by Russell Investment Management Company (“RIMCo”). The Fund intends to be fully invested at all times by
exposing its cash reserves to the performance of appropriate markets by purchasing equity securities and/or derivatives,
which typically include index futures contracts. Please refer to the “Investment Objective and Investment Strategies”
section in the Fund’s Prospectus for further information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:
     • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
       selected may cause a Fund to underperform relative to other funds with similar investment objectives and
       strategies.
     • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
       multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
     • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
       issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
       may involve greater risks because these companies generally have narrower markets, more limited managerial and
       financial resources and a less diversified product offering than larger, more established companies.
     • Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
       transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
       failing to fulfill the obligations of the contract or transaction.
     • REITs. REITs may be affected by changes in the value of the underlying properties owned by the REITs and by
       the quality of tenants’ credit.
     • American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
       currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
       associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
       changes in the exchange rates of foreign currencies.
     • Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
       economic conditions, making those investments difficult to sell. The market price of certain investments may fall
       dramatically if there is no liquid trading market.
     • Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
       counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
       risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
       derivative may not correlate exactly with the change in the value of the underlying asset, rate or index.

                                                            RIF-6
      • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
        in valuing portfolio instruments.
      • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
        adversely affect the value of a security.
      • Large Redemptions. The Fund is used as an investment for certain funds of funds and in asset allocation programs
        and may have a large percentage of its Shares owned by such funds or held in such programs. Large redemption
        activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to
        meet redemptions.
      Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund
varies from year to year. The highest and lowest returns for a full quarter during the periods shown in the bar chart are
set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance Company
Separate Account or Policy charges. Those charges, if included, would have reduced the performance results shown in this
section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with the index returns that measure broad market
performance. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not include fair
valuation adjustments which may be included in fund returns.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same. This example does not reflect any Insurance Company Separate Account or Policy
charges. If it did, the costs shown would have been higher. Although your actual costs may be higher or lower, under
these assumptions your costs would be:

Portfolio Turnover
     The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 150% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies
     The Fund seeks to achieve its objective by concentrating its investments in equity securities of real estate companies
located in a number of countries around the world, including the U.S., in a globally diversified manner. A portion of the
Fund’s securities are denominated in foreign currencies and are typically held outside the U.S. The Fund may invest a
portion of its assets in equity securities of companies that are located in emerging markets. The Fund invests primarily in
securities of companies, known as real estate investment trusts (REITs) and other REIT-like entities that own interests in
real estate or real estate-related loans. The Fund may also invest in equity securities of other types of real estate-related
companies. The Fund has a non-fundamental policy to invest, under normal circumstances, at least 80% of the value of its
net assets in real estate securities. The Fund may invest in large, medium or small capitalization companies. The Fund
may enter into spot or forward currency contracts to facilitate settlement of securities transactions. The Fund employs a
multi-manager approach whereby portions of the Fund are allocated to different money managers whose approaches are
intended to complement one another. Fund assets not allocated to money managers are managed by Russell Investment
Management Company (“RIMCo”). Please refer to the “Investment Objective and Investment Strategies” section in the
Fund’s Prospectus for further information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
      may involve greater risks because these companies generally have narrower markets, more limited managerial and
      financial resources and a less diversified product offering than larger, more established companies.
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.
    • Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
      risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
      the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
      dollar-denominated securities and currencies may reduce the returns of the Fund.
    • Forward Currency Contracts. If forward prices increase, a loss will occur to the extent that the agreed upon
      purchase price of the currency exceeds the price of the currency that was agreed to be sold.
    • Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
      transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
      failing to fulfill the obligations of the contract or transaction.
    • Real Estate Securities. Just as real estate values go up and down, the value of the securities of companies involved
      in the industry also fluctuates. Real estate securities, including REITs, may be affected by changes in the value of
      the underlying properties owned by the companies and by the quality of tenants’ credit.

                                                          RIF-10
         • Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
           economic conditions, making those investments difficult to sell. The market price of certain investments may fall
           dramatically if there is no liquid trading market.
         • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
           in valuing portfolio instruments.
         • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
           adversely affect the value of a security.
         • Large Redemptions. The Fund is used as an investment for certain funds of funds and in asset allocation programs
           and may have a large percentage of its Shares owned by such funds or held in such programs. Large redemption
           activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to
           meet redemptions.
         • Industry Concentration Risk. By concentrating in a single industry, the Fund carries much greater risk of adverse
           developments in that industry than a fund that invests in a wide variety of industries.
         Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund
varies from year to year. The highest and lowest returns for a full quarter during the periods shown in the bar chart are
set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance Company
Separate Account or Policy charges. Those charges, if included, would have reduced the performance results shown in this
section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with the index returns that measure broad market
performance. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not include fair
valuation adjustments which may be included in fund returns.
         Past performance is no indication of future results.

Management

Investment Adviser
     The Fund’s investment adviser is RIMCo. Unlike most investment companies that have a single organization that
acts as investment adviser, the Fund divides responsibility for investment advice between RIMCo and a number of
unaffiliated money managers. The money managers for the Fund are:
    • AEW Capital Management, L.P.                               • INVESCO Advisers, Inc.
    • Cohen & Steers Capital Management, Inc.

Portfolio Manager
   Bruce A. Eidelson has primary responsibility for the management of the Fund. Mr. Eidelson has been a Portfolio
Manager since January 2002.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and

Fees and Expenses of the Fund
     The following tables describe the fees and expenses that you may pay if you buy and hold Shares of the Fund. The
fees and expenses shown in this section do not reflect any Insurance Company Separate Account or Policy charges. Those
charges, if included, would have increased overall fees and expenses. Please refer to your account or policy documents

#      “Other Expenses,” “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” for the Fund have been restated to
       reflect the Fund’s proportionate share of the operating expenses of any other fund, including the Russell U.S. Cash Management Fund, in which
       the Fund invests.
       Until April 30, 2012, RIMCo has contractually agreed to waive 0.06% of its 0.90% advisory fee. This waiver may not be terminated during the
       relevant period except with Board approval.




                                                                                              1

Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year        3 Years         5 Years        10 Years
$109           $352           $614           $1,364

Portfolio Turnover
     The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
      The Fund invests primarily in equity securities, including common stocks and preferred stocks, issued by companies
incorporated in developed markets outside the U.S. and in depositary receipts. The Fund has a non-fundamental policy to
invest, under normal circumstances, at least 80% of the value of its assets in non-U.S. securities. The Fund’s securities are
denominated primarily in foreign currencies and are typically held outside the U.S. The Fund may also invest a portion of
its assets in equity securities of companies that are located in countries with emerging markets or that derive a majority of
their revenues from operating in such countries. The Fund invests primarily in large and medium capitalization
companies, but may also invest in small capitalization companies. The Fund may at times seek to protect its investments
against adverse currency exchange rate changes by purchasing forward currency contracts. The Fund employs a
multi-style (growth, value and market-oriented) and multi-manager approach whereby portions of the Fund are allocated
to different money managers who employ distinct investment styles. Fund assets not allocated to money managers are
managed by Russell Investment Management Company (“RIMCo”). The Fund intends to be fully invested at all times by
exposing its cash reserves to the performance of appropriate markets by purchasing equity securities and/or derivatives,
which typically include index futures contracts. Please refer to the “Investment Objective and Investment Strategies”
section in the Fund’s Prospectus for further information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:
     • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
       selected may cause a Fund to underperform relative to other funds with similar investment objectives and
       strategies.
     • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
       multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
     • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
       issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
       may involve greater risks because these companies generally have narrower markets, more limited managerial and
       financial resources and a less diversified product offering than larger, more established companies. Investments in
       preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make
       the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.




                                                              2

                                                          RIF-16
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.
    • Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
      risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
      the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
      dollar-denominated securities and currencies may reduce the returns of the Fund.
    • Forward Currency Contracts. If forward prices increase, a loss will occur to the extent that the agreed upon
      purchase price of the currency exceeds the price of the currency that was agreed to be sold.
    • Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
      transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
      failing to fulfill the obligations of the contract or transaction.
    • Depositary Receipts. Depositary receipts, which are securities traded on a local stock exchange that represent
      securities issued by a foreign publicly-listed company, are subject to the risks associated with the underlying
      international securities.
    • Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
      economic conditions, making those investments difficult to sell. The market price of certain investments may fall
      dramatically if there is no liquid trading market.
    • Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
      counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
      risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
      derivative may not correlate exactly with the change in the value of the underlying asset, rate or index.
    • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
      in valuing portfolio instruments.
    • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
      adversely affect the value of a security.
    • Large Redemptions. The Fund is used as an investment for certain funds of funds and in asset allocation programs
      and may have a large percentage of its Shares owned by such funds or held in such programs. Large redemption
      activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to
      meet redemptions.
    Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund
varies from year to year. The highest and lowest returns for a full quarter during the periods shown in the bar chart are
set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance Company
Separate Account or Policy charges. Those charges, if included, would have reduced the performance results shown in this
section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with the index returns that measure broad market
performance. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not include fair
valuation adjustments which may be included in fund returns.
    Past performance is no indication of future results.

         holdings) to the Russell Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings). RIMCo believes that the Russell
         Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings) is an appropriate benchmark which more broadly represents
         the investable universe of stocks.

Management

Investment Adviser
     The Fund’s investment adviser is RIMCo. Unlike most investment companies that have a single organization that
acts as investment adviser, the Fund divides responsibility for investment advice between RIMCo and a number of
unaffiliated money managers. The money managers for the Fund are:
         • Barrow, Hanley, Mewhinny & Strauss, LLC                                                      • MFS Institutional Advisors, Inc.
         • Marsico Capital Management, LLC                                                              • Pzena Investment Management, LLC

Portfolio Manager
   James A. Jornlin has primary responsibility for the management of the Fund. Mr. Jornlin has been a Portfolio
Manager since July 1996.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

Investment Objective (Non-Fundamental)
       The Fund seeks to provide current income, and as a secondary objective, capital appreciation.

Fees and Expenses of the Fund
     The following tables describe the fees and expenses that you may pay if you buy and hold Shares of the Fund. The
fees and expenses shown in this section do not reflect any Insurance Company Separate Account or Policy charges. Those
charges, if included, would have increased overall fees and expenses. Please refer to your account or policy documents
for a description of those fees and expenses. Please see the Expense Notes section of the Fund’s Prospectus for further

#      “Other Expenses,” “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” for the Fund have been restated to
       reflect the Fund’s proportionate share of the operating expenses of any other fund, including the Russell U.S. Cash Management Fund, in which
       the Fund invests.
       Until April 30, 2012, RIMCo has contractually agreed to waive 0.07% of its 0.55% advisory fee. This waiver may not be terminated during the
       relevant period except with Board approval.




                                                                                              1

Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year         3 Years         5 Years        10 Years
$71             $236           $416            $938

Portfolio Turnover
     The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in
annual fund operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the
Fund’s portfolio turnover rate was 195% of the average value of its portfolio.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
      The Fund invests primarily in bonds. The Fund may invest up to 25% of its assets in debt securities that are rated
below investment grade (commonly referred to as high-yield or “junk bonds”). The Fund invests a significant portion of
its assets in mortgage related securities, including mortgage-backed securities. The Fund also invests in (1) U.S. and
non-U.S. corporate debt securities, (2) Yankee Bonds (dollar-denominated obligations issued in the U.S. by non-U.S.
banks and corporations), (3) fixed income securities issued or guaranteed by the U.S. government and, to a lesser extent
by non-U.S. governments, or by their respective agencies and instrumentalities and (4) asset-backed securities. The Fund
may invest in variable and floating rate securities. The Fund purchases loans and other direct indebtedness. A majority of
the Fund’s assets are U.S. dollar denominated but the Fund also invests in non-U.S. debt securities, including emerging
market debt securities. The Fund may also invest in derivatives as a substitute for holding securities directly, for hedging
purposes, to take certain short positions or to adjust the Fund’s interest rate sensitivity or duration. The Fund may invest
in futures, options, when-issued securities, forward foreign currency contracts, swaps, swaptions, credit derivatives and
STRIPS. A portion of the Fund’s net assets may be illiquid. The duration of the Fund’s portfolio typically ranges within
20% of the duration of the Barclays Capital U.S. Aggregate Bond Index, but may vary up to 35% from the Index’s
duration. The Fund has a non-fundamental policy to invest, under normal circumstances, at least 80% of the value of its
net assets in bonds. The Fund employs multiple money managers, each with its own investment style. Fund assets not
allocated to money managers are managed by Russell Investment Management Company (“RIMCo”). The Fund intends to
be fully invested at all times by exposing its cash reserves to the performance of appropriate markets or to changes in
interest rates or market/sector returns by purchasing fixed income securities and/or derivatives, which typically include
exchange traded fixed income futures contracts. Please refer to the “Investment Objective and Investment Strategies”
section in the Fund’s Prospectus for further information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:
      • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
        selected may cause a Fund to underperform relative to other funds with similar investment objectives and
        strategies.
      • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
        multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
      • Fixed Income Securities. Prices of fixed income securities generally rise and fall in response to, among other
        things, interest rate changes.

                                                               2

                                                           RIF-22
• Non-Investment Grade Fixed Income Securities (High Yield or “Junk Bonds”). Non-investment grade fixed income
  securities involve higher volatility and higher risk of default than investment grade bonds.
• Government Issued or Guaranteed Securities, U.S. Government Securities. Bonds issued or guaranteed by a
  government are subject to inflation risk and price depreciation risk.
• Mortgage-Backed Securities. Mortgage-backed securities may be affected by, among other things, changes or
  perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator
  of the mortgage, or the quality of the underlying assets. The underlying assets may default or decline in quality or
  value.
• Asset-Backed Securities. Payment of principal and interest on asset-backed securities may be largely dependent
  upon the cash flows generated by the assets backing the securities and asset-backed securities may not have the
  benefit of any security interest in the related assets.
• Loans and Other Direct Indebtedness. Loans and other direct indebtedness involve the risk that payment of
  principal, interest and other amounts due in connection with these investments may not be received.
• Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
  regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
  emerging markets securities.
• Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
  risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
  the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
  dollar-denominated securities and currencies may reduce the returns of the Fund.
• Yankee Bonds and Yankee CDs. Issuers are not necessarily subject to the same regulatory requirements that apply
  to U.S. corporations and banks.
• Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
  counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
  risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
  derivative may not correlate exactly with the change in the value of the underlying asset, rate or index. Credit
  default swaps could result in losses if the creditworthiness of the company or companies on which the credit
  default swap is based is evaluated incorrectly.
• Leveraging Risk. Leverage tends to exaggerate the effect of any increase or decrease in the value of a security.
• Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
  economic conditions, making those investments difficult to sell. The market price of certain investments may fall
  dramatically if there is no liquid trading market.
• Illiquid Securities. An illiquid security may be difficult to sell quickly and at a fair price, which could cause the
  Fund to realize a loss on the security if it was sold at a lower price than that at which it had been valued.
• Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
  transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
  failing to fulfill the obligations of the contract or transaction.
• Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
  in valuing portfolio instruments.
• Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
  adversely affect the value of a security.
• Large Redemptions and Subscriptions. The Fund is used as an investment for certain funds of funds and in asset
  allocation programs and may have a large percentage of its Shares owned by such funds or held in such programs.
  Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio
  securities at a loss to meet redemptions. Additionally, in a rising interest rate environment, large redemptions in
  fixed income funds may result in a lower yield for those funds. Likewise, if interest rates are decreasing, large
  subscription activity may result in a lower yield.
Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing how the performance of the Fund
varies from year to year. The highest and lowest returns for a full quarter during the periods shown in the bar chart are
set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance Company
Separate Account or Policy charges. Those charges, if included, would have reduced the performance results shown in this
section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with the index returns that measure broad market
performance. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not include fair
valuation adjustments which may be included in fund returns.
      Past performance is no indication of future results.

Management

Investment Adviser
     The Fund’s investment adviser is RIMCo. Unlike most investment companies that have a single organization that
acts as investment adviser, the Fund divides responsibility for investment advice between RIMCo and a number of
unaffiliated money managers. The money managers for the Fund are:
      • Goldman Sachs Asset Management, L.P.                                                    • Pacific Investment Management Company LLC
      • Metropolitan West Asset Management, LLC

Portfolio Manager
     Michael R. Ruff has primary responsibility for the management of the Fund. Mr. Ruff has been a Portfolio Manager
since November 2002.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more


                                                                                          4

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

#      “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” have been restated to reflect the proportionate share of the
       expenses of the Underlying Funds in which the Fund invests.
       Until April 30, 2012, RIMCo has contractually agreed to waive up to the full amount of its 0.20% advisory fee and then to reimburse the Fund for
       other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.10% of the average daily net assets of the Fund on an
       annual basis. Direct Fund-level expenses do not include extraordinary expenses or the expenses of other investment companies in which the Fund
       invests, including the Underlying Funds, which are borne indirectly by the Fund. This waiver and reimbursement may not be terminated during
       the relevant period except with Board approval.




                                                                                              1

                                                                                        RLP-1
Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year        3 Years        5 Years        10 Years
$90            $353           $637          $1,446

Portfolio Turnover
     The Fund pays no transaction costs or commissions when it buys and sells Shares of the Underlying Funds. The
Underlying Funds pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs affect the Underlying Funds’
performance. Portfolio turnover rates for the Underlying Funds are available in the Prospectus for the Underlying Funds.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
     The Fund is a “fund of funds,” which seeks to achieve its objective by investing in a combination of several other
Russell Investment Funds (“RIF”) funds or Russell Investment Company (“RIC”) funds (the “Underlying Funds”). RIC is
a registered investment company that has the same investment adviser as RIF. The Fund intends its strategy of investing
in a combination of Underlying Funds to result in investment diversification that an investor could otherwise achieve only
by holding numerous individual investments. The Fund’s approximate target strategic allocation as of May 1, 2011 is
28%-38% to equity Underlying Funds, 53%-63% to fixed income Underlying Funds and 4%-14% to real asset Underlying
Funds. The Underlying Funds employ a multi-manager approach whereby most assets of the Underlying Funds are
allocated to different unaffiliated money managers.
      Russell Investment Management Company (“RIMCo”), the Funds’ investment adviser, may modify the target
allocation for any Fund and/or the Underlying Funds in which a Fund invests from time to time based on capital markets
research or on factors such as RIMCo’s outlook for the economy, financial markets generally and/or relative market
valuation of the asset classes represented by each Underlying Fund. Modifications in the allocations to the Underlying
Funds are typically based on strategic, long-term allocation decisions. A Fund’s actual allocation may vary from the target
strategic asset allocation at any point in time (1) due to market movements, (2) by up to +/- 3% at the equities, fixed
income or real asset category level based on RIMCo’s assessment of relative market valuation of the asset classes
represented by each Underlying Fund, (3) due to the implementation over a period of time of a change to the target
strategic asset allocation including the addition of a new Underlying Fund. There may be no changes in the asset
allocation or to the Underlying Funds in a given year or such changes may be made one or more times in a year.
     The Fund is a “nondiversified” investment company for purposes of the Investment Company Act of 1940 because it
invests in the securities of a limited number of issuers (i.e., the Underlying Funds). However, most of the Underlying
Funds in which the Fund invests are diversified investment companies, and therefore the Fund is less subject to the risks
of greater market fluctuation and price volatility normally associated with nondiversified investment companies.
     Please refer to the “Investment Objective and Investment Strategies” section in the Fund’s Prospectus for further
information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:




                                                             2

                                                         RLP-2
    • Investing in Affiliated Underlying Funds. The assets of the Fund are invested primarily in Shares of the Underlying
      Funds, and the investment performance of the Fund is directly related to the investment performance of the
      Underlying Funds in which it invests. RIMCo is the investment adviser for both the Fund and the Underlying
      Funds and may be deemed to have a conflict of interest in determining the allocation of the Fund to the
      Underlying Funds.
    • Asset Allocation. Neither the Fund nor RIMCo can offer any assurance that the asset allocation of the Fund will
      either maximize returns or minimize risks. Nor can the Fund or RIMCo offer assurance that a recommended
      allocation will be the appropriate allocation in all circumstances for every investor. The value of your investment
      may decrease if RIMCo’s judgment about the attractiveness, value or market trends affecting a particular asset
      class, investment style or Underlying Fund is incorrect. Asset allocation decisions might also result in the Fund
      having more exposure, indirectly through its investments in the Underlying Funds, to asset classes, countries or
      regions, or industries or groups of industries that underperform.
    • Long-Term Viability Risk. There can be no assurance that the Fund will grow to an economically viable size, in
      which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer
      their investments at an inopportune time. You should consider your own investment goals and risk tolerance before
      investing in any Fund.
    The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the allocation of its assets
among the Underlying Funds. The following are the principal risks associated with investing in the Underlying Funds
which are also principal risks of investing in the Fund as a result of its investment in the Underlying Funds:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
      may involve greater risks because these companies generally have narrower markets, more limited managerial and
      financial resources and a less diversified product offering than larger, more established companies. Investments in
      preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make
      the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.
    • Fixed Income Securities. Prices of fixed income securities generally rise and fall in response to, among other
      things, interest rate changes.
    • Non-Investment Grade Fixed Income Securities (High Yield or “Junk Bonds”). Non-investment grade fixed income
      securities involve higher volatility and higher risk of default than investment grade bonds.
    • Government Issued or Guaranteed Securities, U.S. Government Securities. Bonds issued or guaranteed by a
      government are subject to inflation risk and price depreciation risk.
    • Mortgage-Backed Securities. Mortgage-backed securities may be affected by, among other things, changes or
      perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator
      of the mortgage, or the quality of the underlying assets. The underlying assets may default or decline in quality or
      value.
    • Asset-Backed Securities. Payment of principal and interest on asset-backed securities may be largely dependent
      upon the cash flows generated by the assets backing the securities and asset-backed securities may not have the
      benefit of any security interest in the related assets.
    • Loans and Other Direct Indebtedness. Loans and other direct indebtedness involve the risk that payment of
      principal, interest and other amounts due in connection with these investments may not be received.
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.




                                                             3

                                                          RLP-3
• Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
  risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
  the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
  dollar-denominated securities and currencies may reduce the returns of the Fund.
• Forward Currency Contracts. If forward prices increase, a loss will occur to the extent that the agreed upon
  purchase price of the currency exceeds the price of the currency that was agreed to be sold.
• Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
  counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
  risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
  derivative may not correlate exactly with the change in the value of the underlying asset, rate or index. Credit
  default swaps could result in losses if the creditworthiness of the company or companies on which the credit
  default swap is based is evaluated incorrectly.
• Short Sales Risk. A short sale will result in a loss if the price of the security sold short increases between the date
  of the short sale and the date on which the borrowed security must be returned. Short sales may give rise to a
  form of leverage. Leverage tends to exaggerate the effect of any increase or decrease in the value of portfolio
  securities.
• Real Estate Securities. Just as real estate values go up and down, the value of the securities of companies involved
  in the industry also fluctuates. Real estate securities, including REITs, may be affected by changes in the value of
  the underlying properties owned by the companies and by the quality of tenants’ credit.
• American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
  currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
  associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
  changes in the exchange rates of foreign currencies.
• Commodity Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments
  in traditional securities, particularly if the investments involve leverage. The value of commodity-linked derivative
  instruments may be affected by changes in overall market movements, commodity index volatility, changes in
  interest rates or sectors affecting a particular industry or commodity and international economic, political and
  regulatory developments. The use of leveraged commodity-linked derivatives creates an opportunity for increased
  return, but also creates the possibility for a greater loss.
• Bank Obligations. The banking industry may be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic
  cycles. The banking industry may also be impacted by legal and regulatory developments.
• Infrastructure Companies. Infrastructure companies are subject to the risk that: the potential for realized revenue
  volumes is significantly lower than projected and/ or cost overruns; the nature of the concession fundamentally
  changes during the life of the project (e.g., the state sponsor alters the terms); macroeconomic factors such as low
  GDP growth or high nominal interest rates raise the average cost of funding; government regulation may affect
  rates charged to customers; government budgetary constraints impact projects; special tariffs are imposed; and
  changes in tax laws, regulatory policies or accounting standards could be unfavorable. Other risks include
  environmental damage due to a company’s operations or an accident, changes in market sentiment towards
  infrastructure and terrorist acts.
• Master Limited Partnerships (“MLPs”). Investing in MLPs involves certain risks related to investing in the
  underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs that concentrate in a
  particular industry or a particular geographic region are subject to risks associated with such industry or region.
  The benefit derived from the Underlying Fund’s investment in MLPs is largely dependent on the MLPs being
  treated as partnerships for federal income tax purposes.
• Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
  economic conditions, making those investments difficult to sell. The market price of certain investments may fall
  dramatically if there is no liquid trading market.
• Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
  in valuing portfolio instruments.

         • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
           adversely affect the value of a security.
         • Large Redemptions. The Underlying Funds are used as investments for certain funds of funds and may have a
           large percentage of their Shares owned by such funds. Large redemption activity could result in the Underlying
           Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions.
     The officers and Trustees of the Fund currently serve as officers and Trustees of the Underlying Funds. RIMCo
presently serves as investment manager of the Fund and Underlying Funds. Therefore, conflicts may arise as those
persons and RIMCo fulfill their fiduciary responsibilities to the Fund and to the Underlying Funds.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing the performance of the Fund since
the beginning of the Fund’s operation. The highest and lowest returns for a full quarter during the periods shown in the
bar chart are set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance
Company Separate Account or Policy charges. Those charges, if included, would have reduced the performance results
shown in this section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with index returns that measure broad market performance.
The Fund is a Fund of Fund that invests in a variety of asset classes. Therefore, no single index provides an appropriate
basis for comparison. For reference purposes, the indexes presented in the chart below have characteristics that represent
the largest of these asset classes. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not
include fair valuation adjustments which may be included in fund returns.
         Past performance is no indication of future results.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

#      “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” have been restated to reflect the proportionate share of the
       expenses of the Underlying Funds in which the Fund invests.
       Until April 30, 2012, RIMCo has contractually agreed to waive up to the full amount of its 0.20% advisory fee and then to reimburse the Fund for
       other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.10% of the average daily net assets of the Fund on an
       annual basis. Direct Fund-level expenses do not include extraordinary expenses or the expenses of other investment companies in which the Fund
       invests, including the Underlying Funds, which are borne indirectly by the Fund. This waiver and reimbursement may not be terminated during
       the relevant period except with Board approval.




                                                                                              1

                                                                                        RLP-8
Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year        3 Years        5 Years        10 Years
$103           $377           $672          $1,510

Portfolio Turnover
     The Fund pays no transaction costs or commissions when it buys and sells Shares of the Underlying Funds. The
Underlying Funds pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs affect the Underlying Funds’
performance. Portfolio turnover rates for the Underlying Funds are available in the Prospectus for the Underlying Funds.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
     The Fund is a “fund of funds,” which seeks to achieve its objective by investing in a combination of several other
Russell Investment Funds (“RIF”) funds or Russell Investment Company (“RIC”) funds (the “Underlying Funds”). RIC is
a registered investment company that has the same investment adviser as RIF. The Fund intends its strategy of investing
in a combination of Underlying Funds to result in investment diversification that an investor could otherwise achieve only
by holding numerous individual investments. The Fund’s approximate target strategic allocation as of May 1, 2011 is
47%-57% to equity Underlying Funds, 33%-43% to fixed income Underlying Funds and 5%-15% to real asset Underlying
Funds. The Underlying Funds employ a multi-manager approach whereby most assets of the Underlying Funds are
allocated to different unaffiliated money managers.
      Russell Investment Management Company (“RIMCo”), the Funds’ investment adviser, may modify the target
allocation for any Fund and/or the Underlying Funds in which a Fund invests from time to time based on capital markets
research or on factors such as RIMCo’s outlook for the economy, financial markets generally and/or relative market
valuation of the asset classes represented by each Underlying Fund. Modifications in the allocations to the Underlying
Funds are typically based on strategic, long-term allocation decisions. A Fund’s actual allocation may vary from the target
strategic asset allocation at any point in time (1) due to market movements, (2) by up to +/- 3% at the equities, fixed
income or real asset category level based on RIMCo’s assessment of relative market valuation of the asset classes
represented by each Underlying Fund, (3) due to the implementation over a period of time of a change to the target
strategic asset allocation including the addition of a new Underlying Fund. There may be no changes in the asset
allocation or to the Underlying Funds in a given year or such changes may be made one or more times in a year.
     The Fund is a “nondiversified” investment company for purposes of the Investment Company Act of 1940 because it
invests in the securities of a limited number of issuers (i.e., the Underlying Funds). However, most of the Underlying
Funds in which the Fund invests are diversified investment companies, and therefore the Fund is less subject to the risks
of greater market fluctuation and price volatility normally associated with nondiversified investment companies.
     Please refer to the “Investment Objective and Investment Strategies” section in the Fund’s Prospectus for further
information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:




                                                             2

                                                         RLP-9
    • Investing in Affiliated Underlying Funds. The assets of the Fund are invested primarily in Shares of the Underlying
      Funds, and the investment performance of the Fund is directly related to the investment performance of the
      Underlying Funds in which it invests. RIMCo is the investment adviser for both the Fund and the Underlying
      Funds and may be deemed to have a conflict of interest in determining the allocation of the Fund to the
      Underlying Funds.
    • Asset Allocation. Neither the Fund nor RIMCo can offer any assurance that the asset allocation of the Fund will
      either maximize returns or minimize risks. Nor can the Fund or RIMCo offer assurance that a recommended
      allocation will be the appropriate allocation in all circumstances for every investor. The value of your investment
      may decrease if RIMCo’s judgment about the attractiveness, value or market trends affecting a particular asset
      class, investment style or Underlying Fund is incorrect. Asset allocation decisions might also result in the Fund
      having more exposure, indirectly through its investments in the Underlying Funds, to asset classes, countries or
      regions, or industries or groups of industries that underperform.
    • Long-Term Viability Risk. There can be no assurance that the Fund will grow to an economically viable size, in
      which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer
      their investments at an inopportune time. You should consider your own investment goals and risk tolerance before
      investing in any Fund.
    The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the allocation of its assets
among the Underlying Funds. The following are the principal risks associated with investing in the Underlying Funds
which are also principal risks of investing in the Fund as a result of its investment in the Underlying Funds:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
      may involve greater risks because these companies generally have narrower markets, more limited managerial and
      financial resources and a less diversified product offering than larger, more established companies. Investments in
      preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make
      the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.
    • Fixed Income Securities. Prices of fixed income securities generally rise and fall in response to, among other
      things, interest rate changes.
    • Non-Investment Grade Fixed Income Securities (High Yield or “Junk Bonds”). Non-investment grade fixed income
      securities involve higher volatility and higher risk of default than investment grade bonds.
    • Government Issued or Guaranteed Securities, U.S. Government Securities. Bonds issued or guaranteed by a
      government are subject to inflation risk and price depreciation risk.
    • Mortgage-Backed Securities. Mortgage-backed securities may be affected by, among other things, changes or
      perceived changes in interest rates, factors concerning the interests in and structure of the issuer or the originator
      of the mortgage, or the quality of the underlying assets. The underlying assets may default or decline in quality or
      value.
    • Asset-Backed Securities. Payment of principal and interest on asset-backed securities may be largely dependent
      upon the cash flows generated by the assets backing the securities and asset-backed securities may not have the
      benefit of any security interest in the related assets.
    • Loans and Other Direct Indebtedness. Loans and other direct indebtedness involve the risk that payment of
      principal, interest and other amounts due in connection with these investments may not be received.
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.




                                                             3

                                                         RLP-10
• Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
  risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
  the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
  dollar-denominated securities and currencies may reduce the returns of the Fund.
• Forward Currency Contracts. If forward prices increase, a loss will occur to the extent that the agreed upon
  purchase price of the currency exceeds the price of the currency that was agreed to be sold.
• Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
  counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
  risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the
  derivative may not correlate exactly with the change in the value of the underlying asset, rate or index. Credit
  default swaps could result in losses if the creditworthiness of the company or companies on which the credit
  default swap is based is evaluated incorrectly.
• Short Sales Risk. A short sale will result in a loss if the price of the security sold short increases between the date
  of the short sale and the date on which the borrowed security must be returned. Short sales may give rise to a
  form of leverage. Leverage tends to exaggerate the effect of any increase or decrease in the value of portfolio
  securities.
• Real Estate Securities. Just as real estate values go up and down, the value of the securities of companies involved
  in the industry also fluctuates. Real estate securities, including REITs, may be affected by changes in the value of
  the underlying properties owned by the companies and by the quality of tenants’ credit.
• American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
  currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
  associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
  changes in the exchange rates of foreign currencies.
• Commodity Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments
  in traditional securities, particularly if the investments involve leverage. The value of commodity-linked derivative
  instruments may be affected by changes in overall market movements, commodity index volatility, changes in
  interest rates or sectors affecting a particular industry or commodity and international economic, political and
  regulatory developments. The use of leveraged commodity-linked derivatives creates an opportunity for increased
  return, but also creates the possibility for a greater loss.
• Bank Obligations. The banking industry may be particularly susceptible to certain economic factors such as interest
  rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic
  cycles. The banking industry may also be impacted by legal and regulatory developments.
• Infrastructure Companies. Infrastructure companies are subject to the risk that: the potential for realized revenue
  volumes is significantly lower than projected and/ or cost overruns; the nature of the concession fundamentally
  changes during the life of the project (e.g., the state sponsor alters the terms); macroeconomic factors such as low
  GDP growth or high nominal interest rates raise the average cost of funding; government regulation may affect
  rates charged to customers; government budgetary constraints impact projects; special tariffs are imposed; and
  changes in tax laws, regulatory policies or accounting standards could be unfavorable. Other risks include
  environmental damage due to a company’s operations or an accident, changes in market sentiment towards
  infrastructure and terrorist acts.
• Master Limited Partnerships (“MLPs”). Investing in MLPs involves certain risks related to investing in the
  underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs that concentrate in a
  particular industry or a particular geographic region are subject to risks associated with such industry or region.
  The benefit derived from the Underlying Fund’s investment in MLPs is largely dependent on the MLPs being
  treated as partnerships for federal income tax purposes.
• Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
  economic conditions, making those investments difficult to sell. The market price of certain investments may fall
  dramatically if there is no liquid trading market.
• Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
  in valuing portfolio instruments.

      • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
        adversely affect the value of a security.
      • Large Redemptions. The Underlying Funds are used as investments for certain funds of funds and may have a
        large percentage of their Shares owned by such funds. Large redemption activity could result in the Underlying
        Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions.
     The officers and Trustees of the Fund currently serve as officers and Trustees of the Underlying Funds. RIMCo
presently serves as investment manager of the Fund and Underlying Funds. Therefore, conflicts may arise as those
persons and RIMCo fulfill their fiduciary responsibilities to the Fund and to the Underlying Funds.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing the performance of the Fund since
the beginning of the Fund’s operation. The highest and lowest returns for a full quarter during the periods shown in the
bar chart are set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance
Company Separate Account or Policy charges. Those charges, if included, would have reduced the performance results
shown in this section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with index returns that measure broad market performance.
The Fund is a Fund of Fund that invests in a variety of asset classes. Therefore, no single index provides an appropriate
basis for comparison. For reference purposes, the indexes presented in the chart below have characteristics that represent
the largest of these asset classes. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not
include fair valuation adjustments which may be included in fund returns.
      Past performance is no indication of future results.

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

#      “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” have been restated to reflect the proportionate share of the
       expenses of the Underlying Funds in which the Fund invests
       Until April 30, 2012, RIMCo has contractually agreed to waive up to the full amount of its 0.20% advisory fee and then to reimburse the Fund for
       other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.10% of the average daily net assets of the Fund on an
       annual basis. Direct Fund-level expenses do not include extraordinary expenses or the expenses of other investment companies in which the Fund
       invests, including the Underlying Funds, which are borne indirectly by the Fund. This waiver and reimbursement may not be terminated during
       the relevant period except with Board approval.




                                                                                              1

Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year        3 Years        5 Years        10 Years
$110           $406           $723          $1,624

Portfolio Turnover
     The Fund pays no transaction costs or commissions when it buys and sells Shares of the Underlying Funds. The
Underlying Funds pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs affect the Underlying Funds’
performance. Portfolio turnover rates for the Underlying Funds are available in the Prospectus for the Underlying Funds.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
     The Fund is a “fund of funds,” which seeks to achieve its objective by investing in a combination of several other
Russell Investment Funds (“RIF”) funds or Russell Investment Company (“RIC”) funds (the “Underlying Funds”). RIC is
a registered investment company that has the same investment adviser as RIF. The Fund intends its strategy of investing
in a combination of Underlying Funds to result in investment diversification that an investor could otherwise achieve only
by holding numerous individual investments. The Fund’s approximate target strategic allocation as of May 1, 2011 is
62%-72% to equity Underlying Funds, 14%-24% to fixed income Underlying Funds and 9%-19% to real asset Underlying
Funds. The Underlying Funds employ a multi-manager approach whereby most assets of the Underlying Funds are
allocated to different unaffiliated money managers.
      Russell Investment Management Company (“RIMCo”), the Funds’ investment adviser, may modify the target
allocation for any Fund and/or the Underlying Funds in which a Fund invests from time to time based on capital markets
research or on factors such as RIMCo’s outlook for the economy, financial markets generally and/or relative market
valuation of the asset classes represented by each Underlying Fund. Modifications in the allocations to the Underlying
Funds are typically based on strategic, long-term allocation decisions. A Fund’s actual allocation may vary from the target
strategic asset allocation at any point in time (1) due to market movements, (2) by up to +/- 3% at the equities, fixed
income or real asset category level based on RIMCo’s assessment of relative market valuation of the asset classes
represented by each Underlying Fund, (3) due to the implementation over a period of time of a change to the target
strategic asset allocation including the addition of a new Underlying Fund. There may be no changes in the asset
allocation or to the Underlying Funds in a given year or such changes may be made one or more times in a year.
     The Fund is a “nondiversified” investment company for purposes of the Investment Company Act of 1940 because it
invests in the securities of a limited number of issuers (i.e., the Underlying Funds). However, most of the Underlying
Funds in which the Fund invests are diversified investment companies, and therefore the Fund is less subject to the risks
of greater market fluctuation and price volatility normally associated with nondiversified investment companies.
     Please refer to the “Investment Objective and Investment Strategies” section in the Fund’s Prospectus for further
information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:




                                                             2

                                                         RLP-16
    • Investing in Affiliated Underlying Funds. The assets of the Fund are invested primarily in Shares of the Underlying
      Funds, and the investment performance of the Fund is directly related to the investment performance of the
      Underlying Funds in which it invests. RIMCo is the investment adviser for both the Fund and the Underlying
      Funds and may be deemed to have a conflict of interest in determining the allocation of the Fund to the
      Underlying Funds.
    • Asset Allocation. Neither the Fund nor RIMCo can offer any assurance that the asset allocation of the Fund will
      either maximize returns or minimize risks. Nor can the Fund or RIMCo offer assurance that a recommended
      allocation will be the appropriate allocation in all circumstances for every investor. The value of your investment
      may decrease if RIMCo’s judgment about the attractiveness, value or market trends affecting a particular asset
      class, investment style or Underlying Fund is incorrect. Asset allocation decisions might also result in the Fund
      having more exposure, indirectly through its investments in the Underlying Funds, to asset classes, countries or
      regions, or industries or groups of industries that underperform.
    • Long-Term Viability Risk. There can be no assurance that the Fund will grow to an economically viable size, in
      which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer
      their investments at an inopportune time. You should consider your own investment goals and risk tolerance before
      investing in any Fund.
    The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the allocation of its assets
among the Underlying Funds. The following are the principal risks associated with investing in the Underlying Funds
which are also principal risks of investing in the Fund as a result of its investment in the Underlying Funds:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
      may involve greater risks because these companies generally have narrower markets, more limited managerial and
      financial resources and a less diversified product offering than larger, more established companies. Investments in
      preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make
      the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.
    • Fixed Income Securities. Prices of fixed income securities generally rise and fall in response to, among other
      things, interest rate changes.
    • Non-Investment Grade Fixed Income Securities (High Yield or “Junk Bonds”). Non-investment grade fixed income
      securities involve higher volatility and higher risk of default than investment grade bonds.
    • Government Issued or Guaranteed Securities, U.S. Government Securities. Bonds issued or guaranteed by a
      government are subject to inflation risk and price depreciation risk.
    • Loans and Other Direct Indebtedness. Loans and other direct indebtedness involve the risk that payment of
      principal, interest and other amounts due in connection with these investments may not be received.
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.
    • Currency Risk. Non-U.S. securities that trade in, and receive revenues in, non-U.S. currencies are subject to the
      risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that
      the U.S. dollar will decline in value relative to the currency being hedged. As a result, investments in non-U.S.
      dollar-denominated securities and currencies may reduce the returns of the Fund.
    • Forward Currency Contracts. If forward prices increase, a loss will occur to the extent that the agreed upon
      purchase price of the currency exceeds the price of the currency that was agreed to be sold.
    • Derivatives. Derivatives are subject to a number of risks such as liquidity risk, market risk, credit risk, default risk,
      counterparty risk (the risk that the other party in an agreement will fail to perform its obligations) and management
      risk. They also involve the risk of mispricing or improper valuation and the risk that changes in the value of the


                                                              3

                                                          RLP-17
      derivative may not correlate exactly with the change in the value of the underlying asset, rate or index. Credit
      default swaps could result in losses if the creditworthiness of the company or companies on which the credit
      default swap is based is evaluated incorrectly.
    • Short Sales Risk. A short sale will result in a loss if the price of the security sold short increases between the date
      of the short sale and the date on which the borrowed security must be returned. Short sales may give rise to a
      form of leverage. Leverage tends to exaggerate the effect of any increase or decrease in the value of portfolio
      securities.
    • Real Estate Securities. Just as real estate values go up and down, the value of the securities of companies involved
      in the industry also fluctuates. Real estate securities, including REITs, may be affected by changes in the value of
      the underlying properties owned by the companies and by the quality of tenants’ credit.
    • American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
      currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
      associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
      changes in the exchange rates of foreign currencies.
    • Commodity Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments
      in traditional securities, particularly if the investments involve leverage. The value of commodity-linked derivative
      instruments may be affected by changes in overall market movements, commodity index volatility, changes in
      interest rates or sectors affecting a particular industry or commodity and international economic, political and
      regulatory developments. The use of leveraged commodity-linked derivatives creates an opportunity for increased
      return, but also creates the possibility for a greater loss.
    • Bank Obligations. The banking industry may be particularly susceptible to certain economic factors such as interest
      rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic
      cycles. The banking industry may also be impacted by legal and regulatory developments.
    • Infrastructure Companies. Infrastructure companies are subject to the risk that: the potential for realized revenue
      volumes is significantly lower than projected and/ or cost overruns; the nature of the concession fundamentally
      changes during the life of the project (e.g., the state sponsor alters the terms); macroeconomic factors such as low
      GDP growth or high nominal interest rates raise the average cost of funding; government regulation may affect
      rates charged to customers; government budgetary constraints impact projects; special tariffs are imposed; and
      changes in tax laws, regulatory policies or accounting standards could be unfavorable. Other risks include
      environmental damage due to a company’s operations or an accident, changes in market sentiment towards
      infrastructure and terrorist acts.
    • Master Limited Partnerships (“MLPs”). Investing in MLPs involves certain risks related to investing in the
      underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs that concentrate in a
      particular industry or a particular geographic region are subject to risks associated with such industry or region.
      The benefit derived from the Underlying Fund’s investment in MLPs is largely dependent on the MLPs being
      treated as partnerships for federal income tax purposes.
    • Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
      economic conditions, making those investments difficult to sell. The market price of certain investments may fall
      dramatically if there is no liquid trading market.
    • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
      in valuing portfolio instruments.
    • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
      adversely affect the value of a security.
    • Large Redemptions. The Underlying Funds are used as investments for certain funds of funds and may have a
      large percentage of their Shares owned by such funds. Large redemption activity could result in the Underlying
      Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions.
     The officers and Trustees of the Fund currently serve as officers and Trustees of the Underlying Funds. RIMCo
presently serves as investment manager of the Fund and Underlying Funds. Therefore, conflicts may arise as those
persons and RIMCo fulfill their fiduciary responsibilities to the Fund and to the Underlying Funds.
    Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing the performance of the Fund since
the beginning of the Fund’s operation. The highest and lowest returns for a full quarter during the periods shown in the
bar chart are set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance
Company Separate Account or Policy charges. Those charges, if included, would have reduced the performance results
shown in this section.
     The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with index returns that measure broad market performance.
The Fund is a Fund of Fund that invests in a variety of asset classes. Therefore, no single index provides an appropriate
basis for comparison. For reference purposes, the indexes presented in the chart below have characteristics that represent
the largest of these asset classes. Index returns do not reflect deductions for fees, expenses or taxes. Index returns do not
include fair valuation adjustments which may be included in fund returns.
      Past performance is no indication of future results.

*     The Fund first issued Shares on May 1, 2007.
**    Effective January 1, 2011, RIMCo changed the Fund’s secondary benchmark from the MSCI EAFE Index (net of tax on dividends from foreign
      holdings) to the Russell Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings). RIMCo believes that the Russell
      Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings) is an appropriate benchmark which more broadly represents
      the investable universe of stocks.

Management

Investment Adviser
      RIMCo is the investment adviser of the Fund and the Underlying Funds.

Portfolio Manager
   John Greves has primary responsibility for the management of the Fund. Mr. Greves has been an Associate Portfolio
Manager since July 2010.




                                                                                          5

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.

#      “Total Annual Fund Operating Expenses” and “Net Annual Fund Operating Expenses” have been restated to reflect the proportionate share of the
       expenses of the Underlying Funds in which the Fund invests.
       Until April 30, 2012, RIMCo has contractually agreed to waive up to the full amount of its 0.20% advisory fee and then to reimburse the Fund for
       other direct Fund-level expenses to the extent that direct Fund-level expenses exceed 0.10% of the average daily net assets of the Fund on an
       annual basis. Direct Fund-level expenses do not include extraordinary expenses or the expenses of other investment companies in which the Fund
       invests, including the Underlying Funds, which are borne indirectly by the Fund. This waiver and reimbursement may not be terminated during
       the relevant period except with Board approval.




                                                                                              1

                                                                                       RLP-22
Example
    This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other
mutual funds.
     The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your
Shares at the end of those periods. The example also assumes your investment has a 5% return each year and that
operating expenses remain the same (taking into account fee waivers/reimbursements in year 1 only). This example does
not reflect any Insurance Company Separate Account or Policy charges. If it did, the costs shown would have been
higher. Although your actual costs may be higher or lower, under these assumptions your costs would be:

1 Year        3 Years        5 Years        10 Years
$115           $450           $809          $1,819

Portfolio Turnover
     The Fund pays no transaction costs or commissions when it buys and sells Shares of the Underlying Funds. The
Underlying Funds pay transaction costs, such as commissions, when they buy and sell securities (or “turn over” their
portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs affect the Underlying Funds’
performance. Portfolio turnover rates for the Underlying Funds are available in the Prospectus for the Underlying Funds.

Investments, Risks and Performance

Principal Investment Strategies of the Fund
     The Fund is a “fund of funds,” which seeks to achieve its objective by investing in a combination of several other
Russell Investment Funds (“RIF”) funds or Russell Investment Company (“RIC”) funds (the “Underlying Funds”). RIC is
a registered investment company that has the same investment adviser as RIF. The Fund intends its strategy of investing
in a combination of Underlying Funds to result in investment diversification that an investor could otherwise achieve only
by holding numerous individual investments. The Fund’s approximate target strategic allocation as of May 1, 2011 is
75%-85% to equity Underlying Funds, 0%-10% to fixed income Underlying Funds and 10%-20% to real asset Underlying
Funds. The Underlying Funds employ a multi-manager approach whereby most assets of the Underlying Funds are
allocated to different unaffiliated money managers.
      Russell Investment Management Company (“RIMCo”), the Funds’ investment adviser, may modify the target
allocation for any Fund and/or the Underlying Funds in which a Fund invests from time to time based on capital markets
research or on factors such as RIMCo’s outlook for the economy, financial markets generally and/or relative market
valuation of the asset classes represented by each Underlying Fund. Modifications in the allocations to the Underlying
Funds are typically based on strategic, long-term allocation decisions. A Fund’s actual allocation may vary from the target
strategic asset allocation at any point in time (1) due to market movements, (2) by up to +/- 3% at the equities, fixed
income or real asset category level based on RIMCo’s assessment of relative market valuation of the asset classes
represented by each Underlying Fund, (3) due to the implementation over a period of time of a change to the target
strategic asset allocation including the addition of a new Underlying Fund. There may be no changes in the asset
allocation or to the Underlying Funds in a given year or such changes may be made one or more times in a year. The
Fund has a non-fundamental policy to invest, under normal circumstances, at least 80% of the value of its assets in shares
of equity Underlying Funds.
     The Fund is a “nondiversified” investment company for purposes of the Investment Company Act of 1940 because it
invests in the securities of a limited number of issuers (i.e., the Underlying Funds). However, most of the Underlying
Funds in which the Fund invests are diversified investment companies, and therefore the Fund is less subject to the risks
of greater market fluctuation and price volatility normally associated with nondiversified investment companies.
     Please refer to the “Investment Objective and Investment Strategies” section in the Fund’s Prospectus for further
information.

Principal Risks of Investing in the Fund
    An investment in the Fund, like any investment, has risks. The value of the Fund fluctuates and you could lose
money. The principal risks of investing in the Fund are those associated with:


                                                             2

                                                         RLP-23
    • Investing in Affiliated Underlying Funds. The assets of the Fund are invested primarily in Shares of the Underlying
      Funds, and the investment performance of the Fund is directly related to the investment performance of the
      Underlying Funds in which it invests. RIMCo is the investment adviser for both the Fund and the Underlying
      Funds and may be deemed to have a conflict of interest in determining the allocation of the Fund to the
      Underlying Funds.
    • Asset Allocation. Neither the Fund nor RIMCo can offer any assurance that the asset allocation of the Fund will
      either maximize returns or minimize risks. Nor can the Fund or RIMCo offer assurance that a recommended
      allocation will be the appropriate allocation in all circumstances for every investor. The value of your investment
      may decrease if RIMCo’s judgment about the attractiveness, value or market trends affecting a particular asset
      class, investment style or Underlying Fund is incorrect. Asset allocation decisions might also result in the Fund
      having more exposure, indirectly through its investments in the Underlying Funds, to asset classes, countries or
      regions, or industries or groups of industries that underperform.
    • Long-Term Viability Risk. There can be no assurance that the Fund will grow to an economically viable size, in
      which case the Fund may cease operations. In such an event, investors may be required to liquidate or transfer
      their investments at an inopportune time. You should consider your own investment goals and risk tolerance before
      investing in any Fund.
    The Fund is exposed to the same risks as the Underlying Funds in direct proportion to the allocation of its assets
among the Underlying Funds. The following are the principal risks associated with investing in the Underlying Funds
which are also principal risks of investing in the Fund as a result of its investment in the Underlying Funds:
    • Active Security Selection. The securities selected for the portfolio may decline in value. Additionally, securities
      selected may cause a Fund to underperform relative to other funds with similar investment objectives and
      strategies.
    • Multi-Manager Approach. The investment styles employed by the money managers may not be complementary. A
      multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.
    • Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that
      issued them, general market conditions and/or economic conditions. Investments in small capitalization companies
      may involve greater risks because these companies generally have narrower markets, more limited managerial and
      financial resources and a less diversified product offering than larger, more established companies. Investments in
      preferred stocks are subject to the risks of common stocks, as well as the risk that interest rates will rise and make
      the fixed dividend feature, if any, less appealing to investors resulting in a decline in price.
    • Non-U.S. and Emerging Markets Securities. Non-U.S. securities have risks relating to political, economic and
      regulatory conditions in foreign countries. The risks associated with non-U.S. securities may be amplified for
      emerging markets securities.
    • Fixed Income Securities. Prices of fixed income securities generally rise and fall in response to, among other
      things, interest rate changes.
    • Non-Investment Grade Fixed Income Securities (High Yield or “Junk Bonds”). Non-investment grade fixed income
      securities involve higher volatility and higher risk of default than investment grade bonds.
    • Government Issued or Guaranteed Securities, U.S. Government Securities. Bonds issued or guaranteed by a
      government are subject to inflation risk and price depreciation risk.
    • Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a
      transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or
      failing to fulfill the obligations of the contract or transaction.
    • Short Sales Risk. A short sale will result in a loss if the price of the security sold short increases between the date
      of the short sale and the date on which the borrowed security must be returned. Short sales may give rise to a
      form of leverage. Leverage tends to exaggerate the effect of any increase or decrease in the value of portfolio
      securities.
    • Real Estate Securities. Just as real estate values go up and down, the value of the securities of companies involved
      in the industry also fluctuates. Real estate securities, including REITs, may be affected by changes in the value of
      the underlying properties owned by the companies and by the quality of tenants’ credit.

                                                         RLP-24
    • American Depositary Receipts (ADRs) or Global Depositary Receipts (GDRs). ADRs and GDRs have the same
      currency and economic risks as the underlying non-U.S. shares they represent. They are affected by the risks
      associated with non-U.S. securities, such as changes in political or economic conditions of other countries and
      changes in the exchange rates of foreign currencies.
    • Commodity Risk. Exposure to the commodities markets may subject the Fund to greater volatility than investments
      in traditional securities, particularly if the investments involve leverage. The value of commodity-linked derivative
      instruments may be affected by changes in overall market movements, commodity index volatility, changes in
      interest rates or sectors affecting a particular industry or commodity and international economic, political and
      regulatory developments. The use of leveraged commodity-linked derivatives creates an opportunity for increased
      return, but also creates the possibility for a greater loss.
    • Bank Obligations. The banking industry may be particularly susceptible to certain economic factors such as interest
      rate changes, adverse developments in the real estate market, fiscal and monetary policy and general economic
      cycles. The banking industry may also be impacted by legal and regulatory developments.
    • Infrastructure Companies. Infrastructure companies are subject to the risk that: the potential for realized revenue
      volumes is significantly lower than projected and/ or cost overruns; the nature of the concession fundamentally
      changes during the life of the project (e.g., the state sponsor alters the terms); macroeconomic factors such as low
      GDP growth or high nominal interest rates raise the average cost of funding; government regulation may affect
      rates charged to customers; government budgetary constraints impact projects; special tariffs are imposed; and
      changes in tax laws, regulatory policies or accounting standards could be unfavorable. Other risks include
      environmental damage due to a company’s operations or an accident, changes in market sentiment towards
      infrastructure and terrorist acts.
    • Master Limited Partnerships (“MLPs”). Investing in MLPs involves certain risks related to investing in the
      underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs that concentrate in a
      particular industry or a particular geographic region are subject to risks associated with such industry or region.
      The benefit derived from the Underlying Fund’s investment in MLPs is largely dependent on the MLPs being
      treated as partnerships for federal income tax purposes.
    • Liquidity Risk. The market for certain investments may become illiquid under adverse or volatile market or
      economic conditions, making those investments difficult to sell. The market price of certain investments may fall
      dramatically if there is no liquid trading market.
    • Market Volatility. Volatile financial markets can result in greater market and liquidity risk and potential difficulty
      in valuing portfolio instruments.
    • Government Intervention in and Regulation of Financial Markets. Changes in government regulation may
      adversely affect the value of a security.
    • Large Redemptions. The Underlying Funds are used as investments for certain funds of funds and may have a
      large percentage of their Shares owned by such funds. Large redemption activity could result in the Underlying
      Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions.
     The officers and Trustees of the Fund currently serve as officers and Trustees of the Underlying Funds. RIMCo
presently serves as investment manager of the Fund and Underlying Funds. Therefore, conflicts may arise as those
persons and RIMCo fulfill their fiduciary responsibilities to the Fund and to the Underlying Funds.
    Please refer to the “Risks” section in the Fund’s Prospectus for further information.

Performance
     The following bar chart illustrates the risks of investing in the Fund by showing the performance of the Fund since
the beginning of the Fund’s operation. The highest and lowest returns for a full quarter during the periods shown in the
bar chart are set forth next to the bar chart. The performance results shown in this section do not reflect any Insurance
Company Separate Account or Policy charges. Those charges, if included, would have reduced the performance results
shown in this section.
    The table accompanying the bar chart further illustrates the risks of investing in the Fund by showing how the
Fund’s average annual returns for the periods shown compare with index returns that measure broad market performance.
The Fund is a Fund of Fund that invests in a variety of asset classes. Therefore, no single index provides an appropriate

*     The Fund first issued Shares on May 1, 2007.
**    Effective January 1, 2011, RIMCo changed the Fund’s secondary benchmark from the MSCI EAFE Index (net of tax on dividends from foreign
      holdings) to the Russell Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings). RIMCo believes that the Russell
      Developed ex-U.S. Large Cap Index (net of tax on dividends from foreign holdings) is an appropriate benchmark which more broadly represents
      the investable universe of stocks.

Management

Investment Adviser
      RIMCo is the investment adviser of the Fund and the Underlying Funds.

Portfolio Manager

Additional Information

Purchase of Fund Shares
     Each insurance company (“Insurance Company”) places orders for its accounts (“Separate Account”) which hold the
interests of each variable insurance product (“Policy”) owner based on, among other things, the amount of premium
payments to be invested pursuant to such Policies. Individuals may not place orders directly with Russell Investment
Funds (“RIF”) or the Funds. See the prospectus of the Separate Account and Policies of the Insurance Company for more
information on the purchase of Fund Shares and with respect to the availability for investment in specific Funds. The
Funds do not issue share certificates. Any minimum or subsequent investment requirements are governed by the
applicable Policy through which you invest.
    For more information about how to purchase Shares, please see Additional Information About Purchase of Fund
Shares in the Funds’ Prospectus.




                                                                                          5

Redemption of Fund Shares
     Shares may be redeemed at any time by Insurance Companies on behalf of their Separate Accounts or their general
accounts. Individuals may not place redemption orders directly with RIF or the Funds. Redemption requests for Fund
shares are based on premiums and transaction requests represented to the Funds by each Insurance Company as having
been received prior to 4:00 p.m., Eastern Time or the close of the NYSE, whichever is earlier on any business day of the
Funds.
    For more information about how to redeem Shares, please see Additional Information About Redemption of Fund
Shares in the Funds’ Prospectus.

Taxes
     Provided that the Funds and Separate Accounts of Insurance Companies investing in the Funds satisfy applicable tax
requirements, the Funds will not be subject to federal tax. Special tax rules apply to Insurance Companies, variable
annuity contracts and variable life insurance contracts. For a discussion of the taxation of life insurance companies and
the separate accounts, as well as the tax treatment of the Policies and the holders thereof, see the discussion regarding
“Federal Tax Considerations” included in the prospectus for the Policies.
    For more information about Taxes, please see Additional Information About Taxes in the Funds’ Prospectus.

Servicing Arrangements
     Some Insurance Companies have entered into arrangements with Russell Fund Services Company (“RFSC”) and/or
Russell Financial Services, Inc. (the “Distributor”) pursuant to which they may receive compensation from RFSC and/or
the Distributor, from RFSC’s and/or the Distributor’s own resources, for administrative and/or other services provided by
those Insurance Companies. These payments may create a conflict of interest by influencing the Insurance Company and
your salesperson to recommend the Funds or a Fund over another investment or by influencing an Insurance Company’s
decision to include the Funds as an underlying investment option in its Policy. Ask your salesperson or visit your
Insurance Company’s web site for more information.
