     *  Portfolio securities and other financial instruments for which market
        quotations are readily available are stated at market value. The Fund's
        investments are valued daily by an independent pricing service. Prices
        obtained from an independent pricing service use information provided by
        market makers or estimates of market values obtained from yield data
        relating to investments or securities with similar characteristics.
        Short-term investments maturing in sixty days or less are valued at
        amortized cost, if their original maturity was 60 days or less or by
        amortizing their value on the 61st day prior to maturity, if the
        original term to maturity exceeded 60 days. Securities for which market
        quotations are not readily available or if a development/event occurs
        that may significantly impact the value of the security may be fair
        valued, pursuant to guidelines established by the Board of Trustees. The
        prices used by the Fund to value securities may differ from the value
        that would be realized if the securities were sold. The Fund's net asset
        value is determined daily at the close of regular trading (normally 4:00
        p.m. Eastern time) on the New York Stock Exchange.

(a)     144A Security - Security exempt from registration under Rule 144A of the
        Securities Act of 1933. These securities may be resold in transactions
        exempt from registration, typically to qualified institutional
        investors.

(b)     Pre-refunded bonds are collateralized by U.S. Government or other
        eligible securities which are held in escrow and used to pay principal
        and interest and retire the bonds at the earliest refunding date.

(c)     Variable Rate Notes - instruments whose interest rates change on
        specified date (such as a coupon date or interest payment date) and/or
        whose interest rates vary with changes in a designated base rate (such
        as the prime interest rate).

(d)     Residual Interest/Tax Exempt Municipal Bonds. The interest rate shown
        bears an inverse relationship to the interest rate on another security
        or the value of an index.

(e)     All or partial principal amount segregated as initial margin on
        futures contracts.

(f)     Non-income producing security.
