o     Effective June 1, 2008, the Fund 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:

            o     Level 1 - price quotations in active markets/exchanges for
                  identical securities
            o     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)
            o     Level 3 - unobservable inputs based on the best information
                  available in the circumstance, to the extent observable inputs
                  are not available (including the Fund'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 Fund's policy regarding valuation of investments
      and other significant accounting policies, please refer to the Fund's most
      recent financial statements as contained in its annual report.

      The following table summarizes the inputs used as of August 31, 2008 in
      determining the fair valuation of the Fund's investments:
