Total Annual Fund Operating Expenses                                                                2.32%
Fee Waiver and/or Expense Reimbursement (a)                                                         1.16%

(a) The Fund’s adviser has contractually agreed to waive its management fee and, if necessary, to reimburse other operating expenses of
    the Fund in order to limit total annual ordinary operating expenses to 1.15% of the Fund’s average daily net assets, excluding interest,
    taxes, brokerage commissions and other investment related costs and extraordinary expenses such as litigation or other expenses
    incurred in the ordinary course of business. The Fund’s Expense Limitation Agreement shall terminate upon the earlier of the
    termination of the Advisory Agreement or July 31, 2020. The Fund’s adviser may discontinue the Expense Limitation Agreement at
    any time after its expiration date.

Expense Example
The example is intended to help you compare the cost of investing in the Fund to 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 that your investment has a 5% return each year and
that the Fund’s operating expenses remain the same. The expense example assumes that the adviser’s agreement to
waive fees and/or reimburse expenses expires on July 31, 2020. Although your actual costs may be higher
or lower, based on these assumptions your costs would be:

                             1-Year                  3-Year                  5-Year                 10-Year
                              $118                    $369                    $639                   $1,414

You would pay the following expenses if you did not redeem your shares:

                             1-Year                  3-Year                  5-Year                 10-Year
                              $118                    $369                    $639                   $1,414

Fund Summary

     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 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 64% of the average
     value of its portfolio.

     Principal Investment Strategies
     Under normal circumstances, the Fund invests primarily in equity securities of non-US companies of all sizes. Under
     normal market conditions, at least 80% of its net assets will be invested in equity securities. Equity securities include
     common stocks and related securities, such as preferred stock, convertible securities and depositary receipts. Non-US
     companies are broadly defined to include any company that meets one of the following tests:
        • its country of organization, its primary business office and/or the principal trading market of its stock are located
          outside of the US
        • 50% or more of its assets are located in a country other than the US
        • 50% or more of its revenues are derived from outside of the US
     In choosing investments, the manager applies a fundamental, bottom-up approach. The managers generally seek
     companies which it believes can offer above average growth sustainably, or those whose growth has been underestimated
     by the market.
     Normally, the Fund’s investments will be divided among Continental Europe, the United Kingdom, Japan and the markets
     of the Pacific Basin. However, selective investments may also be made in Latin America and in other parts of the world.
     The Fund may invest in emerging markets and may invest in new companies, both through initial public offerings and
     private placements.
     The Fund may also invest a substantial amount of its assets (i.e., more than 25% of its assets) in issuers located in a
     single country or a limited number of countries.
     The Fund may use derivatives for both hedging and nonhedging purposes. Derivatives are financial instruments whose
     value is derived from the value of another security, a commodity (such as gold or oil), currency or an index. Examples of
     derivatives include forwards, options, contracts for differences, indexed securities, swaps, futures and options on futures.
     To the extent the Fund purchases derivatives, they may be used to enhance potential gain, to manage or adjust the risk
     profile of the Fund, to replace more traditional direct investments, or to obtain exposure to certain markets. Using
     derivatives may involve greater risks to the Fund than investing directly in securities.
     The Fund generally sells a stock when, in the managers’ opinion, there is deterioration in the company’s fundamentals, the
     company fails to meet performance expectations, the stock achieves its target price, its earnings are disappointing or its
     revenue growth has slowed. The Fund may also sell a stock if the managers believe that negative country or regional
     factors may affect the company’s outlook, if, in the managers’ opinion, a superior investment opportunity arises or to meet
     cash requirements. Some of the Fund’s investments may produce income, although income from dividends and interest will
     be incidental and not an important consideration in choosing investments.
     The Fund may engage in active and frequent trading to achieve its investment objective. The Fund does not limit its
     investments to companies of any particular size and may invest a significant portion of its assets in smaller and less
     seasoned issuers. However, in an attempt to reduce portfolio risks, the managers will invest across countries, industry
     groups and/or securities.

                                                                                                              Fund Summary

Principal Investment Risks
You can lose money by investing in the Fund and your investment in the Fund may not perform as well as other similar
investments. As with any fund, the value of the Fund’s investments and therefore the value of the Fund’s shares as well as
the amount of any dividend paid may fluctuate significantly. The Fund may not achieve its investment objective, and is not
intended as a complete investment program. An investment in the Fund is not a deposit in a bank and is not insured or
guaranteed by the Federal Deposit Insurance Corporation or any other government agency.
The principal risks that could adversely affect the total return on your investment include:
   • Market and Equity Securities Risk. The risk that the stock price of one or more of the companies will fall, or will fail
     to rise. Many factors can adversely affect a stock’s performance, including both general financial market conditions
     and factors related to a specific company or industry. Because the Fund’s portfolio primarily consists of common
     stocks, it is expected that the Fund’s net asset value (NAV) will be subject to greater price fluctuation than a portfolio
     containing primarily fixed income securities.
   • Smaller and Less Seasoned Companies Risk. The risk that the Fund may invest in securities issued by smaller
     companies and in less seasoned issuers, including through initial public offerings and private placements. Smaller
     companies and, to a greater extent, less seasoned companies, may have more limited product lines, markets and
     financial resources than larger, more seasoned companies and, especially in the case of initial public offerings
     and private placements, their securities may trade less frequently and in more limited volume than those of larger,
     more mature companies, and the prices of their securities may be more volatile than those of larger, more
     established companies.
   • Foreign Investments Risk. The risks of investing outside the U.S. include currency fluctuations, economic or
     financial insolvency, a lack of timely or reliable financial information, possible imposition of foreign withholding taxes
     or unfavorable political or legal developments. These risks are typically greater in less developed or emerging
     market countries.
   • Emerging Markets Risk. The risks of foreign investments are typically greater in less developed countries, which
     are sometimes referred to as emerging markets. For example, political and economic structures in these countries
     may be changing rapidly, which can cause instability and greater risk of loss. These countries are also more likely to
     experience higher levels of inflation, deflation or currency devaluation, which could hurt their economies and
     securities markets. For these and other reasons, investments in emerging markets are often considered speculative.
   • Non-Diversification Risk. The risk that, because the Fund may invest a higher percentage of its assets in a small
     number of issuers, the Fund is more susceptible to any single economic, political or regulatory event affecting one or
     more of those issuers than is a diversified fund.
   • Frequent Trading Risk. The risk that frequent buying and selling of investments will involve higher trading costs and
     other expenses that may affect the Fund’s performance over time. High rates of portfolio turnover may result in the
     realization of short-term capital gains, which could adversely affect the after tax return on your investment in the
     Fund. Any distributions resulting from such gains will be considered ordinary income for federal income tax purposes.
     The Fund’s portfolio turnover rate may be 100% or more.
   • Geographic Focus Risk. To the extent the Fund invests a substantial amount of its assets in issuers located in a
     single country or region, developments in these economies will generally have a greater effect on the Fund than they
     would on a more geographically diversified fund, which may result in greater losses and volatility.
   • Derivatives Risk. Derivatives involve special risks different from, and potentially greater than, the risks associated
     with investing directly in securities and may result in greater losses. The successful use of derivatives depends on
     the managers’ ability to manage these sophisticated instruments, which require investment techniques and risk
     analysis different from those of other investments. Derivatives involve the risk of mispricing or improper valuation
     and the prices of derivatives may move in unexpected ways especially in unusual market conditions, and may result
     in increased volatility and unexpected losses. Some derivatives are “leveraged” and therefore may magnify or
     otherwise increase investment losses. The use of derivatives may also increase the amount of taxes payable by
     shareholders. Other risks arise from the managers’ potential inability to terminate or sell derivatives positions. A
     liquid secondary market may not always exist for a Fund’s derivatives positions at any time. In fact, many over-the-
     counter instruments (investments not traded on an exchange) are not liquid. Over-the-counter instruments also
     involve the risk that the other party to the derivative transaction will not meet its obligations. Derivatives also may
     involve credit and interest rate risks. In addition, the risks associated with the use of derivatives are magnified to the
     extent that a larger portion of the Fund’s assets are committed to derivatives in general or are invested in a few
     types of derivatives.

   • Redemptions initiated by the Fund.
For shares purchased through a financial intermediary,
shareholders should contact their financial intermediary for
more information on whether the redemption fee is applied
to their shares. In some cases, financial intermediaries
investing wrap account assets through an omnibus account
may charge the 2.00% redemption fee but apply
operational policies or procedures that are more or less
restrictive than those of the Fund.
In-Kind Distributions. The Fund has reserved the right to
pay redemption proceeds by a distribution in-kind of
portfolio securities (rather than cash). In-kind distributions
are taxable in the same manner as cash distributions. In
the event that the Fund makes an in-kind distribution, you
could incur the brokerage and transaction charges when
converting the securities to cash. Should the in-kind
distribution contain illiquid securities, you could have
difficulty converting the assets into cash. The Fund has
elected under Rule 18f-1 of the 1940 Act to commit to pay,
during any 90-day period, your redemption proceeds in
cash up to either $250,000 or 1% of the Fund’s net assets,
whichever is less.

     Investor Services and Programs

     As a shareholder of the Fund, you have available to you a
     number of services and investment programs.

     Distribution Options
     The following distribution options are generally available
     to all accounts and you may change your distribution
     option as often as you desire by contacting shareholder
     services directly:
        • Dividend and net capital gain distributions reinvested
          in additional shares (this option will be assigned if no
          other option is specified)
        • Dividend distributions in cash; net capital gain
          distributions reinvested in additional shares
        • Dividend and net capital gain distributions in cash
        • Dividend and net capital gain distributions reinvested
          in additional shares of another Henderson Fund of
          your choice
     Reinvestments (net of any tax withholding) will be made in
     additional full and fractional shares at the NAV as of the
     close of business on the reinvestment date, which is the
     NAV next computed for the Fund. See “Other Information-
     Undeliverable Distributions.” Your request to change a
     distribution option must be received by shareholder
     services at least five business days before a distribution in
     order to be effective for that distribution. No interest will
     accrue on amounts represented by uncashed distribution
     or redemption checks.

supply the appropriate documentation to the Fund. Backup
withholding will not be applied to payments that have been
subject to non-resident alien withholding. Prospective

Application for additional information regarding backup
withholding of federal income tax.
Taxability of Transactions. When you redeem, sell or
exchange shares, it is generally considered a taxable event
for you, unless you are a tax-exempt holder of Fund
shares, such as a qualified retirement plan. Depending on
the type of account in which you hold shares of the Fund,
and depending on the purchase price and the sale price of
the shares you redeem, sell or exchange, you may realize
a gain or a loss on the transaction for federal income tax
purposes. The gain or loss will generally be treated as
long-term capital gain or loss if the shares were held for
more than one year and, if not held for such period, as
short-term capital gain or loss. You are responsible for any
tax liabilities generated by your transactions.

Unique Nature of the Fund
Henderson and its affiliates may serve as the investment
adviser to other funds which have investment goals and
principal investment policies and risks similar to those of
the Fund, and which may be managed by the Fund’s
portfolio managers. While the Fund may have many
similarities to these other funds, its investment
performance will differ from the other funds’ investment
performance. This is due to a number of differences
between the funds, including differences in sales charges,
expense ratios, investments and cash flows.

Provision of Annual and Semi-Annual
Reports and Prospectus
The Fund produces financial reports every six months
and updates the Prospectus annually. To avoid sending
duplicate copies of materials to households, only one
copy of the Fund’s annual and semi-annual report or
Prospectus will be mailed to shareholders having the same
residential address on the Fund’s records. However, any
shareholder may contact shareholder services (see back
cover for address and phone number) to request that
copies of these reports and the Prospectus be sent
personally to that shareholder.

     Financial Highlights

     The financial highlights table is intended to help you understand the Fund’s financial performance for the period of the Fund’s
     operations. Certain information reflects financial results for a single Fund share. The total returns in the table represent the
     rate that an investor would have earned (or lost) on an investment in a particular class of the Fund (assuming reinvestment of
     all dividends and distributions). The information has been audited by Ernst & Young LLP, independent registered public
     accounting firm. The independent registered public accounting firm’s report, along with the Fund’s financial statements, are
     included in the annual report of the Fund, and are incorporated by reference into the Statement of Additional Information. You
     may obtain the annual report without charge by calling 800.657.1493.
