NR - NOT RATED

     Industry percentages are calculated as a percentage of net assets
     applicable to common shares.

(a)  This Senior Loan interest is non-income producing.

(b)  A portion of this security is designated in connection with unfunded
     commitments.

(c)  This borrower has filed for protection in federal bankruptcy court.

(d)  Affiliated company.

(e)  Non-income producing security as this stock or warrant currently does not
     declare dividends.

(f)  Restricted Security. Securities were acquired through the restructuring of
     senior loans. These securities are restricted as they are not allowed to be
     deposited via the Depository Trust Company. If at a later point in time,
     the company wishes to register, the issuer will bear the costs associated
     with registration. The aggregate value of restricted securities represents
     0.02% of the net assets applicable to common shares of the Trust.

(g)  Payment-in-kind security.

(h)  Variable rate security. Interest rate shown is that in effect at October
     31, 2006.

(i)  This borrower is currently in liquidation.

(j)  The borrower is in the process of restructuring or amending the terms of
     this loan.

(k)  144A securities are those which are exempt from registration under Rule
     144A of the Securities Act of 1933, as amended. These securities may only
     be resold in transactions exempt from registration which are normally those
     transactions with qualified institutional buyers.

(l)  Subsequent to October 31, 2006, this borrower has filed for protection in
     federal bankruptcy court.

+    Bank Loans rated below Baa by Moody's Investor Service, Inc. or BBB by
     Standard & Poor's Group are considered to be below investment grade. Bank
     loan ratings are unaudited.

*    Senior Loans in the Trust's portfolio 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 in the Trust's portfolio
     may occur. As a result, the actual remaining maturity of Senior Loans held
     in the Trust's portfolio may be substantially less than the stated
     maturities shown. Although the Trust is unable to accurately estimate the
     actual remaining maturity of individual Senior Loans, the Trust estimates
     that the actual average maturity of the Senior Loans held in its portfolio
     will be approximately 18-24 months.

**   Senior Loans in which the Trust invests generally pay interest at rates
     which are periodically redetermined by reference to a base lending rate
     plus a premium. These base lending rates are generally (i) the lending rate
     offered by one or more major European banks, such as the London Inter-Bank
     Offered Rate ("LIBOR"), (ii) the prime rate offered by one or more major
     United States banks and (iii) the certificate of deposit rate. Senior Loans
     are generally considered to be restricted in that the Trust ordinarily is
     contractually obligated to receive approval from the Agent Bank and/or
     Borrower prior to the disposition of a Senior Loan.
