risks and opportunities in relation to ESG
Key Issues (e.g., carbon emissions). Each company is scored on a scale of 0 to 10, with 10 being the highest, for each Key Issue before being
assigned an ESG rating based on average Key Issue score. Only the securities of companies with an MSCI ESG
rating of “BB” or higher are eligible for inclusion in the Underlying Index. Additionally, MSCI excludes companies involved in very severe business controversies by assessing the possible negative environmental,
social, and/or governance impact of a company’s operations or products on a scale from zero to ten,
with zero being the most severe controversy rating (the “MSCI Controversies Score”). For new constituents, only securities of companies with a MSCI Controversies Score of three or higher are eligible for
inclusion in the Underlying Index. Current constituents must have a MSCI Controversies Score of at least
one.
Following these eligibility screens, companies are then ranked based on ESG rating, which is adjusted based on a company's sector membership (as described below) and free
float-adjusted market capitalization. The top constituents in each sector based on this ranking mechanism
are selected until the Underlying Index achieves approximately 50% sector coverage by cumulative free
float-adjusted market capitalization. Sectors of the Parent Index are determined according to the Global
Industry Classification Standard. In order to evaluate a security’s ESG rating for a given sector,
the Index Provider identifies key ESG issues that can lead to unexpected costs for companies in the medium- to long-term. The Index Provider then calculates the size of each company’s exposure to each key issue based on the
company’s business segment and geographic risk and analyzes the extent to which companies have
developed robust strategies and programs to manage ESG risks and opportunities. Using a sector-specific key
issue weighting model, companies are rated and ranked in comparison to their industry peers. Because ESG
ratings are calculated in comparison to a company’s sector peers, securities in one sector may have a
lower average ESG rating than securities in another sector. As of August 31, 2024, 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.
Changes to the components of the Underlying Index are implemented annually at the end
of May. Such changes update the eligible universe of securities included in the Underlying Index and
reflect further rebalances necessary to target 50% free float-adjusted market capitalization of each sector of the Parent Index. As of August 31, 2024, the Underlying Index includes approximately 299 component securities.
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 90% of its assets in the component securities of the Underlying Index and may
invest up to 10% 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 sponsored by MSCI, 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.
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.
ESG Risk. To the extent that the Underlying Index uses criteria related to the ESG characteristics of issuers, this may limit the
