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 significantly impact the value of a security are fair-valued, in good faith, pursuant to guidelines established by the Board of Trustees. The Fund’s investments are valued daily using prices supplied by an independent pricing service or dealer quotations, or are valued at the last sale price on the exchange that is the primary market for such securities, or the quoted mean price for those securities for which the over-the-counter market is the primary market or for listed securities in which there were no sales. Independent pricing services use 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 securities maturing in 60 days or less are valued at amortized cost, if their original term to 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 as of the close of regular trading (normally, 4:00 p.m. Eastern time) on the New York Stock Exchange (‘‘NYSE’’) on each day the NYSE is open for business.
(a)  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 (payment date) and/or whose interest rates vary with changes in a designated base rate (such as the prime interest rate).
(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. Unless otherwise indicated, these securities are not considered to be illiquid.
(c)  Inverse Floater – 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 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 interest rate disclosed reflects the rate in effect on December 31, 2006.
(e)  All or partial amount segregated as collateral for futures contracts and/or written options.
(f)  Non-income producing.
(g)  Residual Interest Bonds held in Trust – Securities represent underlying bonds transferred to a separate securitization trust established in a tender option bond transaction in which the Fund acquired the residual interest certificates. These securities serve as collateral in a financing transaction.
(h)  Less than $500.

Item 2. Controls and Procedures

(a) The registrant’s President and Chief Executive Officer and Principal Financial Officer have concluded that the registrant’s disclosure controls and procedures (as defined in Rule 30a-2(c) under the Investment Company Act of 1940, as amended are effective based on their evaluation of these controls and procedures as of a date within 90 days of the filing date of this document.

Prior to reaching this conclusion, the principal officers had become aware of matters relating to the Registrant’s participation in certain inverse floater structures that required enhancements to certain controls. The Registrant’s management determined that controls relating to the review and analysis of relevant terms and conditions of certain transfers of securities under the provisions of Statement of Financial Accounting Standards No. 140 ‘‘Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities’’ (‘‘SFAS 140’’) were not effective.

The Registrant’s Management is taking such further actions as are necessary to revise its disclosure controls and procedures in order to increase the effectiveness of these controls with respect to the accounting treatment of transfers of certain inverse floater transactions.

(b) There were no significant changes in the registrant’s internal controls or in factors that could affect these controls subsequent to the date of their evaluation, including any corrective actions with regard to significant deficiencies and material weaknesses. However, as discussed above, subsequent to December 31, 2006, the Registrant enhanced controls related to the accounting treatment of transfers of certain inverse floater transactions.
