  • Effective September 1, 2008, the Trust adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:

     
     
  • Level 1 - price quotations in active markets/exchanges for identical

     
     
  • Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs)

     
     
  • Level 3 - unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Trust's own assumption used in determining the fair value of investments)

     
     

    The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. For information about the Trust's policy regarding valuation of investments and other significant accounting policies, please refer to the Trust's most recent financial statements as contained in its annual report.

     
     

    The following table summarizes the inputs used as of November 30, 2008 in determining the fair valuation of the Trust's investments:

     
      Valuation     Investments in     Investments Sold       Other Financial      
      Inputs     Securities     Short       Instruments*      
      Level 1   $ 227,892,107     -     $ (6,906,285 )    
      Level 2     442,321,351   $ (21,790,752 )     5,310,373
