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 or persons acting at their discretion pursuant to guidelines established by the Board of Trustees, including certain fixed income securities which may be valued with reference to securities whose prices are more readily available. The Fund’s investments, including over-the -counter options, are valued daily using prices supplied by an independent pricing service or dealer quotations, or by using the last sale price on the exchange that is the primary market for such securities, or the last 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. The Fund’s investments in senior floating rate loans (“Senior Loans”), for which a secondary market exists will be valued at the mean of the last available bid and asked prices in the market for such Senior Loans, as provided by an independent pricing service. Other Senior Loans, are valued at fair value pursuant to procedures approved by the Board of Trustees. Exchange traded options, futures and options on futures are valued at the settlement price determined by the relevant exchange. Securities purchased on a when-issued or delayed-delivery basis are marked to market daily until settlement at the forward settlement value. Short-term investments 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 normally determined 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)		Private Placement—Restricted as to resale and may not have a readily available market. Securities with an aggregate value of $170,340,137, representing 11.41% of total investments.
(b)		Illiquid security.
(c)		These securities generally pay interest at rates which are periodically pre-determined by reference to a base lending rate plus a premium. These base lending rates are generally either the lending rate offered by one or more major European banks, such as the “LIBOR” or the prime rate offered by one or more major United States banks, or the certificate of deposit rate. These securities are generally considered to be restricted as the Fund is ordinarily contractually obligated to receive approval from the Agent bank and/or borrower prior to disposition. Remaining maturities of senior loans may be less than the stated maturities shown as a result of contractual or optional payments by the borrower. Such prepayments cannot be predicted with certainty.
(d)		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.
(e)		When-issued or delayed-delivery security. To be settled/delivered after February 29, 2008.
(f)		Fair-valued security—Securities with an aggregate value of $19,702,964, representing 1.32% of total investments.
(g)		Perpetual maturity security. Maturity date shown is date of first call. Interest rate is fixed until the first call date and variable thereafter.
(h)		All or partial amount segregated as collateral for future contracts, swap contracts and/or options written.
(i)		Non-income producing.
(j)		Residual Interest Bonds held in Trust—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.

Fair Value Measurements–Effective December 1, 2007, the Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, Fair Value Measurements (“FAS 157”). This standard clarifies the definition of fair value for financial reporting, establishes a framework for measuring fair value and requires additional disclosures about the use of the fair value measurements. The three levels of the fair value hierarchy under FAS 157 are described below:

· Level 1 – quoted prices in active markets for identical investments

· Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

· Level 3 – significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following is a summary of the inputs used as of February 29, 2008 in valuing the Fund’s investments carried at value:

	Investments in	Other Financial
Valuation Inputs	Securities	Instruments
Level 1 - Quoted Prices	$9,358,473	$(2,825,737	)
Level 2 - Other Significant Observable Inputs	1,446,073,752	6,788,341
Level 3 - Significant Unobservable Inputs	24,950,840	—
Total	$1,480,383,065	$3,962,604
