| (a) | Industry and/or sector classifications used in this report are generally according to the Global Industry Classification Standard, which was developed by and is the exclusive property and a service mark of MSCI Inc. and Standard & Poor’s. |
| (b) | Calculated as a percentage of net assets. Amounts in excess of 100% are due to the Trust’s use of leverage. |
| (c) | Security purchased or received in a transaction exempt from registration under the Securities Act of 1933, as amended (the “1933 Act”). The security may be resold pursuant to an exemption from registration under the 1933 Act, typically to qualified institutional buyers. The aggregate value of these securities at May 31, 2021 was $82,267,982, which represented 84.78% of the Trust’s Net Assets. |
| (d) | All or a portion of this security is Pay-in-Kind. Pay-in-Kind securities pay interest income in the form of securities. |
| (e) | Security issued at a fixed rate for a specific period of time, after which it will convert to a variable rate. |
| (f) | Perpetual bond with no specified maturity date. |
| (g) | Variable rate senior loan interests often require prepayments from excess cash flow or permit the borrower to repay at its election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with any accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, it is anticipated that the variable rate senior loan interests will have an expected average life of three to five years. |
| (h) | Variable rate senior loan interests are, at present, not readily marketable, not registered under the 1933 Act and may be subject to contractual and legal restrictions on sale. Variable rate senior loan interests in the Trust’s portfolio generally have variable rates which adjust to a base, such as the London Interbank Offered Rate (“LIBOR”), on set dates, typically every 30 days, but not greater than one year, and/or have interest rates that float at margin above a widely recognized base lending rate such as the Prime Rate of a designated U.S. bank. |
| (i) | Security valued using significant unobservable inputs (Level 3). See Note 1. |
| (j) | Foreign denominated security. Principal amount is denominated in the currency indicated. |
| (k) | Non-income producing security. |
| (l) | Affiliated issuer. The issuer and/or the Trust is a wholly-owned subsidiary of Invesco Ltd., or is affiliated by having an investment adviser that is under common control of Invesco Ltd. The table below shows the Trust’s transactions in, and earnings from, its investments in affiliates for the three months ended May 31, 2021. |
