*       Portfolio securities are valued at the last quoted sale price or closing
        values. If this is 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.
