   –Concentration of capital affords most efficient use
    across all other contracting parties

 NGX Central Clearing Benefits

  Exposure                                     • Is the risk reduction
  • Will I get paid?                             worth the cost?
  • Will my gas get

• Risk Mitigation “Trade-Off”
    – When a Contracting Party introduces risk to the clearing
      operation (ex. Receivable exposure or Mark-to-Market
      losses) they must provide collateral to support the risk
    – In return, all Contracting Parties that are exposed to the
      clearing operation due to the introduction of risk (ex.
      Payable positions and Mark-to-Market gains) are secured
      against defaults

Position Tracking
• Consolidation and Netting
   –Positions within each product and date range are
    consolidated into gross long and short positions
   –Risk is managed against the net of the long and short
• Instruments and Date Ranges
    –Trades across all instruments in a product are
     grouped by date ranges in real-time
    –Instruments may overlap, but date ranges are unique
    –Ex. A M-Nov instrument and a WB-Nov instrument
     would each populate a position for November 1 to
     November 30th

Exchange Exposure Management
• Collateral Requirements
   –To the fullest extent possible, NGX enforces stringent
     collateral policies to protect Contracting Parties
• Risk Measurement
    –NGX must accurately determine and measure risks to
     ensure the collective security of Contracting Parties
• Risk Mitigation Tools
    –NGX utilizes globally accepted, standard
     clearinghouse practices such as penalty mechanisms
     and liquidation provisions to mitigate the introduction
     of risks to the clearing operation

Performance Risks
• Failure to Make/Take Delivery
   –NGX is exposed to the price at which an alternative
     supply/market can be found
   –Risk is managed with backstopping contracts, penalty
     mechanisms, collateral requirements and credit policy
• Failure to Pay
   –NGX is exposed to receivables risk on settlement
   –Risk is managed with penalty mechanisms, collateral
     requirements and credit policy
• Failure to Provide Collateral
   –NGX is exposed to the risk that Contracting Parties
     will not provide sufficient collateral to manage their
   –Risk is managed with liquidation provisions

• Collateral Policy
   –Contracting Parties must have sufficient collateral to
     cover their Margin Requirement, utilizing any
     combination of the forms of collateral and offsets
   –Collateral is held to support the Contracting Party’s
     traded positions and can only be used to remedy a
     performance failure by the Contracting Party pledging
     the collateral
• Collateral Requirements
   –Collateral is accepted in the form of cash and
     irrevocable letter of credit from an A or higher rated
   –Collateral requirement can be reduced with an
     accounts payable or positive variation margin offset

Margin Requirements
• Risk Measurement
    –NGX measures risk in real-time and calculates
     margin requirements to quantify the risk
• Margin Requirements and Collateral
   –If margin requirements reach 80% of collateral
    pledged, NGX will request additional collateral
   –At 90%, NGX will halt the Contracting Parties
    trading capabilities
   –At 95%, NGX is entitled to invoke the liquidation

Physical Risk Measurement
• Accounts Receivable/Payable
   –A calculation of the value of gas delivered
   –Margin requirements are increased if gas has been
     taken prior to payment, and decreased if gas has
     been delivered prior to payment
• Variation Margin (Mark-to-Market)
   –A calculation of the price at which a forward position
     could be instantaneously liquidated given current
     market prices
• Initial Margin
    –A calculation of the probability of a movement in
      market prices during a two-day holding period
    –Initial margin coverage protects against a prolonged

Swap Risk Measurement
• Accounts Receivable/Payable
   –A calculation of the value of the final gain/loss on the
     swap, also called the Swap Clearing Amount
   –Swap Clearing Amounts that result in payment
     obligations will increase the Swap Margin
• Variation Margin (Mark-to-Market)
   –A calculation of the price at which a forward position
     could be instantaneously liquidated given current

What are Initial Margins?
• Defined
   –Initial Margin is an estimation of the value to which
     the clearing house might be exposed during a period
     of liquidation
   –Initial Margin is intended to measure potential
     change in a value of a portfolio beyond the last mark-
     to-market price during a period of liquidation
• How Does NGX Utilize Initial Margin?
   –NGX applies initial margin to Contracting Parties’ net
    open positions that would be subject to liquidation in
    the event of a default
   –Initial margin acts as additional position coverage
    that NGX can utilize in the event of a default to
    ensure that the clearing operation remains secure

Initial Margin Methodology
• Utilization of VaR
   –NGX utilizes a Value-at-Risk methodology to
      determine initial margins
   –VaR is a method of assessing risk that uses standard
      statistical techniques routinely used in a variety of
      technical fields
   –VaR measures the worst expected loss over a given
      time interval under normal market conditions at a
      given confidence level
   –VaR, while imperfect and subject to several
      limitations, provides a measurement tool that is
      generally considered adequate to evaluate potential
      exposure in a portfolio

Margin Offsetting
• Accounts Receivable/Payable
   –All receivables/payables are offset across all NGX
• Variation Margin (Mark-to-Market)
   –All mark-to-market calculations are offset across all
     NGX products
• Initial Margin
    –Initial margin is offset on all net forward positions for
      a single product profile when the positions have
      known, fixed settlement values
    –Initial margin offsets will be available for net forward
      positions across different product profiles (cross-
      margining) that are highly correlated historically

Margin Example
• Example
   –On Monday, June 24, BUYCO (buyer) purchases
     5,000 GJ/Day of the NGX Intra-Alberta month of
     July 2002 physical contract from SELLCO (seller) at
     a price of CAD $3.500/GJ
• Position Management
   –As soon as the transaction is matched, BUYCO
     shows a net long position of 5,000 GJ for each day
     from July 1 to July 31, thus a total net long position
     of 155,000 GJ (ie. 5,000 GJ/Day multiplied by 31
   –Conversely, SELLCO shows a net short position of
     5,000 GJ for each day from July 1 to July 31, thus a
     total net short position of 155,000 GJ

Margin Example
• Initial Margin
    –Immediately following the creation of the long and
      short positions, initial margin is applied
    –The initial margin rate for July is currently CAD
      $0.600/GJ, as statistically generated by NGX
    –Both BUYCO and SELLCO must have collateral
      deposited with NGX to cover the initial margin
      requirement, ie. CAD $93,000 (155,000 GJ multiplied
      by $0.600/GJ)
    –The initial margin requirement will remain in place,
      unchanged, until one of the following events occurs:
        • Either BUYCO or SELLCO offset all or part of their
          open long/short position, thus reducing their
          initial margin requirement to zero, or;
        • The July long/short position becomes a current
          month position on July 1st

  Margin Example
• Mark-to-Market
   –The following table illustrates the margin
    requirements for the July position through each
    remaining day in June:
