(i)	Zero coupon bond issued at a discount.
(j)	Advance refunded; secured by an escrow fund of U.S. Government obligations or other highly rated collateral.
(k)	Security is subject to a reimbursement agreement which may require the Trust to pay amounts to a counterparty in the event of a significant decline in the market value of the security underlying the TOB Trusts. In case of a shortfall, the maximum potential amount of payments the Trust could ultimately be required to make under the agreement is $23,650,000. However, such shortfall payment would be reduced by the proceeds from the sale of the security underlying the TOB Trusts.
(l)	Convertible capital appreciation bond. The interest rate shown represents the coupon rate at which the bond will accrue at a specified future date.
(m)	Security valued using significant unobservable inputs (Level 3). See Note 1.
(n)	Demand security payable upon demand by the Trust at specified time intervals no greater than thirteen months. Interest rate is redetermined periodically by the issuer or agent based on current market conditions. Rate shown is the rate in effect on November 30, 2023.
(o)	Entities may either issue, guarantee, back or otherwise enhance the credit quality of a security. The entities are not primarily responsible for the issuer’s obligations but may be called upon to satisfy the issuer’s obligations. No concentration of any single entity was greater than 5% each.
(p)	Floating rate note obligations related to securities held. The interest and fee rates shown reflect the rates in effect at November 30, 2023. At November 30, 2023, the Trust’s investments with a value of $131,123,265 are held by TOB Trusts and serve as collateral for the $92,855,000 in the floating rate note obligations outstanding at that date.

The valuation policy and a listing of other significant accounting policies are available in the most recent shareholder report.

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 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.
