All percentages shown in the Portfolio of Investments are based on net assets applicable to Common shares unless otherwise noted.
   
 
 (2)  
Senior Loans in which the Fund invests generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate plus an assigned fixed rate. These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks.
   
 
   
Senior Loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the Agent Bank and/or Borrower prior to the disposition of a Senior Loan.
   
 
 (3)  
Senior Loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a Borrower to prepay, prepayments of Senior Loans may occur. As a result, the actual remaining maturity of Senior Loans held may be substantially less than the stated maturities shown.
   
 
 (4)  
Ratings: Using the higher of Standard & Poor’s or Moody’s rating. Ratings below BBB by Standard & Poor’s Group or Baa by Moody’s Investor Service, Inc. are considered to be below investment grade.
   
 
 (5)  
At or subsequent to October 31, 2006, this issue was under the protection of the Federal Bankruptcy Court.
   
 
 (6)  
Position represents an unfunded Senior Loan commitment outstanding at October 31, 2006. At October 31, 2006, the Fund had unfunded Senior Loan commitments of $3,803,021.
   
 
 (7)  
Negative value represents unrealized depreciation on Senior Loan commitment at October 31, 2006.

Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration which are normally those transactions with qualified institutional buyers.
   
 
TBD  
Senior Loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, Senior Loans typically trade without accrued interest and therefore a weighted average coupon rate is not available prior to settlement. At settlement, if still unknown, the Borrower or counterparty will provide the Fund with the final weighted average coupon rate and maturity date.
   
 
(PIK)  
In lieu of cash payment, interest accrued on “Payment in Kind” investment increases principal outstanding.
   
 
Income Tax Information
The following information is presented on an income tax basis. Differences between amounts for financial statement and federal income tax purposes are primarily due to the treatment of paydown gains and losses, recognition of premium amortization and timing differences in recognizing certain gains and losses on investment transactions.
At October 31, 2006, the cost of investments was $654,371,122.
Gross unrealized appreciation and gross unrealized depreciation of investments at October 31, 2006, were as follows:
