Invesco Master Loan Fund

Notes to Schedule of Investments:

^(a)  Principal amounts are denominated in U.S. dollars unless otherwise noted.

^(b)  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.

^(c)  Variable rate senior loan interests are, at present, not readily marketable, not registered under the Securities Act of 1933, as amended (the “1933 Act”) and may be subject to contractual and legal restrictions on sale. Variable rate senior loan interests in the Fund’s portfolio generally have variable rates which adjust to a base, such as the Secured Overnight Financing Rate (“SOFR”), 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.

^(d)  Security valued using significant unobservable inputs (Level 3). See Note 1.

^(e)  Foreign denominated security. Principal amount is denominated in the currency indicated.

^(f)  Security purchased or received in a transaction exempt from registration under 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 November 30, 2023 was $254,793, which represented 1.79% of the Fund’s Net Assets.

^(g)  Interest or dividend rate is redetermined periodically. Rate shown is the rate in effect on November 30, 2023.

^(h)  Non-income producing security.

⁽ⁱ⁾  Affiliated holding. Affiliated holdings are investments in entities which are under common ownership or control of Invesco Ltd. or are investments in entities in which the Fund owns 5% or more of the outstanding voting securities. The table below shows the Fund’s transactions in, and earnings from, its investments in affiliates for the three months ended November 30, 2023.

Notes to Quarterly Schedule of Portfolio Holdings

November 30, 2023

(Unaudited)

NOTE 1–Additional Valuation Information

Generally Accepted Accounting Principles (“GAAP”) defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under current market conditions. GAAP establishes a hierarchy that prioritizes the inputs to valuation methods, giving the highest priority to readily available unadjusted quoted prices in an active market for identical assets (Level 1) and the lowest priority to significant unobservable inputs (Level 3), generally when market prices are not readily available. Based on the valuation inputs, the securities or other investments are tiered into one of three levels. Changes in valuation methods may result in transfers in or out of an investment’s assigned level:

Level 1 -	Prices are determined using quoted prices in an active market for identical assets.
Level 2 -	Prices are determined using other significant observable inputs. Observable inputs are inputs that other market participants may use in pricing a security. These may include quoted prices for similar securities, interest rates, prepayment speeds, credit risk, yield curves, loss severities, default rates, discount rates, volatilities and others.
Level 3 -	Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable (for example, when there is little or no market activity for an investment at the end of the period), unobservable inputs may be used. Unobservable inputs reflect Invesco Advisers, Inc.’s (the “Adviser”) assumptions about the factors market participants would use in determining fair value of the securities or instruments and would be based on the best available information.

    The following is a summary of the tiered valuation input levels, as of November 30, 2023. The level assigned to the securities valuations may not be an indication of the risk or liquidity associated with investing in those securities. Because of the inherent uncertainties of valuation, the values reflected in the financial statements may materially differ from the value received upon actual sale of those investments.

    A reconciliation of Level 3 investments is presented when the Fund had a significant amount of Level 3 investments at the beginning and/or end of the reporting period in relation to net assets.

    The following is a reconciliation of the fair valuations using significant unobservable inputs (Level 3) during the three months ended November 30, 2023:

*Transfers into and out of Level 3 are due to increases or decreases in market activity impacting the available market inputs to determine the price.

    Securities determined to be Level 3 at the end of the reporting period were valued primarily by utilizing evaluated prices from a third-party vendor pricing service. A significant change in third-party pricing information could result in a lower or higher value in Level 3 investments.
