NR - NOT RATED

+     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.

      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 segregated in connection with unfunded
      loan 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 0.04% 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 April 30,
      2005.

(i)   This borrower is currently in liquidation.

   *  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.


Item 2.  Controls and Procedures.

(a) The Trust's principal executive officer and principal financial officer have
concluded that the Trust's disclosure controls and procedures are sufficient to
ensure that information required to be disclosed by the Trust in this Form N-Q
was recorded, processed, summarized and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms, based
upon such officers' evaluation of these controls and procedures as of a date
within 90 days of the filing date of the report.

(b) There were no changes in the Trust's internal control over financial
reporting that occurred during the registrant's fiscal quarter that has
materially affected, or is reasonably likely to materially affect, the Trust's
internal control over financial reporting.

Item 3.  Exhibits.

(a)      A certification for the Principal Executive Officer of the registrant 
is attached hereto as part of EX-99.cert.

(b)      A certification for the Principal Financial Officer of the registrant 
is attached hereto as part of EX-99.cert.
