At March 31, 2019, the cost of investment securities for tax purposes was $167,768,319. There were no unrealized gains or losses.

Accounting principles generally accepted in the United States (GAAP) establish a disclosure hierarchy that categorized the inputs used to value assets and liabilities at measurement date. These inputs are summarized into three broad levels as follows:

Level 1 - quoted prices in active markets for identical investments;

Level 2 - other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.); and

Level 3 - significant unobservable inputs (including the Fund’s own assumptions in determining the fair valuation of investments).

The inputs or methodologies used to value securities are not necessarily an indication of the risk associated with investing in those securities. Changes in valuation techniques may result in transfers in or out of an investment’s assigned level within the hierarchy during the period. For more information regarding the Fund’s valuation policies please refer to the Fund’s most recent financial report.

The Level 3 security was not considered to be material.

Fair Value Hierarchy as of Period End

Various inputs are used in determining the fair value of investments and derivative financial instruments. 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 for identical assets or liabilities that Master Portfolio has the ability to access
•	Level 2 – Other observable inputs (including, but not limited to, quoted prices for similar assets or liabilities in markets that are active, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates) or other market–corroborated inputs)
•	Level 3 – Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available (including the Fund’s own assumptions used in determining the fair value of investments)

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 BlackRock Global Valuation Methodologies Committee (the “Global 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. Level 3 investments may also be adjusted to reflect illiquidity and/or non-transferability, with the amount of such discount estimated by the Global Valuation Committee in the absence of market information.

Changes in valuation techniques may result in transfers into or out of an assigned level within the hierarchy. In accordance with the Fund’s policy, transfers between different levels of the fair value hierarchy are deemed to have occurred as of the beginning of the reporting period. The categorization of a value determined for investments is based on the pricing transparency of the investments and is not necessarily an indication of the risks associated with investing in those securities. For information about the Fund’s policy regarding valuation of investments, refer to the Fund’s most recent financial statements as contained in its annual report.

The following table summarizes the Fund's investments categorized in the disclosure hierarchy:

	Level 1	Level 2	Level 3	Total
Assets:
Investments:
Long-Term Investments: Common Stocks(a)	$19,101,341,775	$—	$—	$19,101,341,775

(a)	See above Schedule of Investments for values in each industry.
(b)	Derivative financial instruments are futures contracts. Futures contracts are valued at the unrealized appreciation (depreciation) on the instrument.

During the period ended March 31, 2019, there were no transfers between levels.
