*           Portfolio securities and other financial instruments for which market quotations are readily available are stated at market value. Portfolio securities and other financial instruments for which market quotations are not readily available or if a development/event occurs that may significantly impact the value of a security, may be fair-valued, in good faith, pursuant to guidelines established by the Board of Trustees. The Fund’s investments are valued daily by an independent pricing service. The independent pricing service uses information provided by market makers or estimates of market values obtained from yield data relating to investments or securities with similar characteristics. Exchange traded options and futures, are valued at the settlement price determined by the relevant exchange. Short-term investments maturing in 60 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. 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) Pre-refunded bonds — 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.
(b) 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 only to qualified institutional buyers.
(c) 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.
(d) Variable Rate Notes — Instruments whose interest rates change on a 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). The rate shown is the rate in effect August 31, 2005.
(e) Maturity date shown is date of next call.
(f) All or partial amount segregated as initial margin on futures contracts.
