            Various inputs are used in determining the value of the Fund's
            investments.  These inputs are summarized in the three broad
            levels listed below.
            Highest priority is given to Level 1 inputs and lowest priority
                 is given to Level 3.
          Level 1 - quoted prices in active markets for identical securities
            Level 2 - other significant observable inputs (including quoted
                prices for similar securities, interest rates, prepayment
		speeds,
                credit risk, etc.)
            Level 3 - significant unobservable inputs (including the Fund's
                own assumptions in determining fair value of investments)

            The following is a summary of the inputs used as of October
            31, 2009, in valuing the Fund's assets:
