*    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.
