   *     Portfolio securities are valued at the last quoted sale price or
         closing values. If these are unavailable, then the average of the
         closing bid and asked prices is used. If there is no asked price, the
         security is valued at the closing bid price on that day. Debt
         instruments are valued at the average of the closing bid and asked
         prices. If the security matures in 60 days or less and is not
         credit-impaired, it is valued at amortized cost. All securities and
         assets for which market quotations are not readily available or any
         security that the Board determines does not reflect its fair market
         value are valued in good faith under procedures established by the
         Board.

               or 240.15d-15(b)).

         (b)   There were no changes in the  registrant's  internal control over
               financial  reporting (as defined in Rule 30a-3(d)  under the 1940
               Act (17 CFR  270.30a-3(d))  that occurred during the registrant's
