Fair Value Hierarchy as of Period End
Various inputs are used in determining the fair value of financial instruments at the measurement date. These inputs to valuation techniques are categorized into a fair value hierarchy consisting of three broad levels for financial reporting purposes as follows: 
• Level 1 – Unadjusted price quotations in active markets/exchanges that the Trust has the ability to access for identical, unrestricted assets or liabilities;
• Level 2 – Inputs other than quoted prices included within level 1 that are observable for the asset or liability, either directly or indirectly; and
• Level 3 – Inputs that are unobservable and significant to the  entire fair value measurement for the asset or liability (including the Valuation Committee’s assumptions used in determining the fair value of financial instruments).
The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). Accordingly, the degree of judgment exercised in determining fair value is greatest for instruments categorized in Level 3. The inputs used to measure fair value may fall into different levels of the fair value hierarchy.  In such cases, for disclosure purposes, the fair value hierarchy classification is determined based on the lowest level input that is significant to the fair value measurement in its entirety. Investments classified within Level 3 have significant unobservable inputs used by the Valuation Committee in determining the price for Fair Valued Investments. Level 3 investments include equity or debt issued by privately held companies or funds. There may not be a secondary market, and/or there are a limited number of investors. The categorization of a value determined for financial instruments is based on the pricing transparency of the financial instruments and is not necessarily an indication of the risks associated with investing in those securities. For information about the Trust’s policy regarding valuation of financial instruments, refer to its most recent financial statements.
The following table summarizes the Trust’s financial instruments categorized in the fair value hierarchy.  The breakdown of the Trust’s financial instruments into major categories is disclosed in the Schedule of Investments above.

(a)
Any difference between net change in unrealized appreciation (depreciation) and net change in unrealized appreciation (depreciation) on investments still held at September 30, 2024 is
generally due to investments no longer held or categorized as Level 3 at period end.
The following table summarizes the valuation approaches used and unobservable inputs utilized by the BlackRock Valuation Committee (the “Valuation Committee”) to determine the value of certain of the Trust’s Level 3 financial instruments as of period end. The table does not include Level 3 financial instruments with values based upon unadjusted third-party pricing information in the amount of $23. A significant change in third party information could result in a significantly lower or higher value of such Level 3 financial instruments.
