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 Capital Management LLC’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.
As of December 31, 2023, all of
the securities in the Trust were valued based on Level 1 inputs (see the Schedule of Investments for security categories). 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.
