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)
