Fund Description

Principal Investment Strategies
Under normal circumstances, the Fund invests at least 80% (and, typically, substantially all) of its net assets (plus the amount of any borrowings for investment purposes) in the equity securities of companies included within the S&P 500  Index (the “Index”). The Fund invests in the equity securities of companies included in the Index in weightings that approximate the relative composition of the securities contained in the Index, and in S&P 500 Index futures contracts. The Index is a widely recognized, unmanaged index representative of common stocks of larger capitalized U.S. companies. As of December 31, 2025, the market capitalization range of companies included in the Index was $5.54 billion to $4.53 trillion. If the securities represented in the Index were to become concentrated in any particular industry, the Fund’s investments would likewise be concentrated in securities of issuers in that industry; the Index is not currently concentrated in any single industry.
The Fund is passively managed, which means it tries to replicate the investment composition and performance of the Index by using computer programs and statistical procedures. The Fund’s  subadviser, BlackRock Investment Management, LLC (“BlackRock”), will buy and sell securities in response to changes in the Index. The Fund may use Index futures contracts, a type of derivative, to gain exposure to the Index in lieu of
investing in cash, or to reduce its exposure to the Index while it sells the securities in its portfolio. Use of Index futures contracts by the Fund may create investment leverage. Because the Fund, unlike the Index, is subject to fees and transaction expenses, the Fund’s returns are likely to be less than those of the Index. BlackRock expects that, under normal circumstances, the annual performance of the Fund, before fees and expenses, will track the performance of the Index within a 0.95 correlation coefficient.
The Fund intends to be diversified in approximately the same proportion as the Index is diversified. The Fund may become “non-diversified,” as defined in the Investment Company Act of 1940, as amended (the “1940 Act”), solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Index. In these circumstances, the Fund may hold larger positions in a smaller number of issuers than a diversified fund. Shareholder approval will not be sought if the Fund becomes “non-diversified” due solely to a change in the relative market capitalization or index weighting of one or more constituents of the Index.
