Portfolio Turnover. The Fund may pay transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are
not reflected in the Annual Fund Operating Expenses or in the Example, affect the Fund’s performance.
During the most recent fiscal year, the Fund's portfolio turnover rate was 3% of the average value of its
portfolio.
Principal Investment Strategies
The Fund seeks to track the investment results of the S&P 500 (the “Underlying Index”), which measures the performance of the
large-capitalization sector of the U.S. equity market, as determined by S&P Dow Jones Indices LLC (the
“Index Provider” or “SPDJI”). As of March 31, 2025, the
Underlying Index included approximately 87.86% of the market capitalization of all publicly traded U.S.
equity securities. The securities in the Underlying Index are weighted based on the float-adjusted market value of their outstanding shares. The Underlying Index consists of securities from a broad range of industries. As of March 31,
2025, a significant portion of the Underlying Index is represented by securities of companies in the
technology industry or sector. The components of the Underlying Index are likely to change over
time.
BFA uses an indexing approach to try to achieve the Fund’s investment objective. The Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.
Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce
some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower
costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively
managed investment companies.
BFA uses a representative sampling
indexing strategy to manage the Fund. “Representative sampling” is an indexing
strategy that involves investing in a representative sample of securities that collectively has an
investment profile similar to that of an applicable underlying index. The securities selected are expected
to have, in the aggregate, investment characteristics (based on factors such as market capitalization and
industry weightings), fundamental characteristics (such as return variability and yield) and liquidity
measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.
The Fund generally will invest at least 80% of its assets in the component securities of its Underlying Index and may
invest up to 20% of its assets in certain futures, options and swap contracts, cash and cash equivalents,
including shares of money market funds advised by BFA or its affiliates, as well as in securities not
included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index.
Cash and cash equivalent investments associated with a derivative position will be treated as part of that
position for the purposes of calculating the percentage of investments included in the Underlying Index. The
Fund seeks to track the investment results of the Underlying Index before fees and expenses of the
Fund.
The Fund
may lend securities representing up to one-third of the value of the Fund's total assets (including the value of any collateral received).
The Underlying Index is a product of SPDJI, which
is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the
Underlying Index and publishes information regarding the market value of the Underlying Index.
Industry Concentration Policy. The Fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated.
For purposes of this limitation, securities of the U.S. government (including its agencies and
instrumentalities) and repurchase agreements collateralized by U.S. government securities are not
considered to be issued by members of any industry.
Diversification Policy. The Fund intends to be diversified in approximately the same proportion as the Underlying Index is diversified. The Fund may become “non-diversified,” as defined in the Investment Company Act of 1940 (the “1940 Act”), solely as a result of a change in relative market capitalization or index weighting of one or more constituents of the Underlying Index. 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 Underlying Index. The Fund discloses its portfolio holdings and weightings at www.iShares.com.
Summary of Principal Risks
As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain
risks, including the principal risks noted below any of which may adversely affect the Fund's net asset
value per share
(“NAV”), trading price, yield, total return and ability to meet its investment objective. Certain key risks are prioritized below (with others following in alphabetical order), but the relative
significance of any risk is difficult to predict and may change over time. You should review each risk
factor carefully.
Risk of Investing
in the U.S. Investing in U.S. issuers subjects the Fund to legal, regulatory, political, currency, security, and economic risks that are specific to the U.S. Certain
changes in the U.S., such as a weakening of the U.S. economy or a decline in its financial markets, may
have an adverse effect on U.S. issuers.
Large-Capitalization Companies Risk. Large-capitalization companies may be less able than smaller-capitalization companies to adapt to changing market conditions and competitive challenges. Large-capitalization companies may be more mature and subject to more limited growth potential
compared with smaller-capitalization companies. The performance of large-capitalization companies could
trail the overall performance of the broader securities markets.
Equity Securities Risk. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. The value of a security may decline for a number of reasons that may directly relate to the issuer as
well as due to
