Notes to Schedule of Investments:

*    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 impact the
     value of the 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. Prices obtained from an
     independent pricing service use information provided by market makers or
     estimates of market value obtained from yield data relating to investments
     or securities with similar characteristics. 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. Exchange
     traded options, futures, and options on futures are valued at the
     settlement price determined by the relevant exchange. 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.

     Securities Act of 1933. These securities may be resold in transactions

(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
