              Various inputs are used in determining the value of the Trust'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 Trust's
                  own assumptions in determining fair value of investments)
