business interruptions, product obsolescence,
third-party vendor risks, cyber attacks, trade disputes, product recalls, liability claims, scarcity of
materials or parts, excess capacity, changes in consumer preferences, and volatility in commodity prices and
currencies. The performance of such companies may also be affected by technological developments, labor
relations, legislative and regulatory changes, government spending policies, and changes in domestic and
international economies.
Issuer
Risk. The performance of the Fund depends on the performance of individual securities or other assets to which the Fund has exposure. The value of securities or other
assets may decline, or perform differently from the market as a whole, due to changes in the financial
condition or credit rating of the issuer or counterparty.
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.
Large Shareholder and Large-Scale Redemption Risk.
Certain shareholders of the Fund, including an Authorized Participant, a third-party investor, the
Fund’s adviser, an affiliate of the Fund’s adviser, a market maker, or another entity, may from time to time own or manage a substantial amount of Fund shares, or may hold their investment in the Fund for a limited period of
time. There can be no assurance that any large shareholder or large group of shareholders would not redeem
their investment. Redemptions of a large number of Fund shares could require the Fund to dispose of assets
to meet the redemption requests, which can accelerate the realization of taxable income and/or capital gains and cause the Fund to make taxable distributions to its shareholders earlier than the Fund otherwise would have. In addition,
under certain circumstances, non-redeeming shareholders may be treated as receiving a disproportionately
large taxable distribution during or with respect to such year. In some circumstances, the Fund may hold a
relatively large proportion of its assets in cash in anticipation of large redemptions, diluting its investment returns. These large redemptions may also force the Fund to sell portfolio securities or other assets when it might not otherwise
do so, which may negatively impact the Fund’s NAV, increase the Fund’s brokerage costs and/or
have a material effect on the market price of Fund shares.
Management Risk. The Fund generally does not attempt to take defensive positions under any market conditions, including declining markets. As the Fund will not fully replicate the Underlying Index and may hold securities or other assets not
included in the Underlying Index, it is subject to the risk that the investment strategy of BFA may not
produce the intended results. There is no guarantee that the Fund’s investment results will have a
high degree of correlation to those of the Underlying Index or that the Fund will achieve its investment objective.
Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares (including through a trading halt), losses from
trading in secondary markets, periods of high volatility, and disruptions in
the process of creating and redeeming Fund
shares. Any of these factors, among others, may lead to the Fund’s shares trading in the secondary
market at a premium or discount to NAV or to the intraday value of the Fund’s portfolio holdings. If you buy Fund shares at a time when the market price is at a premium to NAV or sell Fund shares at a time when the market price is at
a discount to NAV, you may pay significantly more or receive significantly less than the underlying value
of the Fund shares.
Materials Companies
Risk. Materials companies may be adversely affected by volatility in commodity prices, changes in exchange rates, social and political unrest, war,
depletion of resources, lower demand, overproduction, litigation and government regulations, among other
factors.
Mid-Capitalization
Companies Risk. Compared to large-capitalization companies, mid-capitalization companies may be less stable and more susceptible to adverse developments. The securities of mid-capitalization companies may be more volatile and less liquid than those of large-capitalization
companies. As a result, the Fund’s share price may be more volatile than that of a fund with a
greater investment in large-capitalization stocks.
National Closed Market Trading Risk. To the extent that securities or other assets held by the Fund trade on foreign exchanges or in foreign markets that may be closed when the
securities exchange on which the Fund’s shares trade is open, there are likely to be deviations
between such asset’s current price and its last quoted price (i.e., the quote from the closed foreign market to the Fund). The impact of a closed foreign market on the Fund is likely to be greater where a large portion of the Fund’s holdings trade on a closed foreign
market or when a foreign market is closed for unscheduled reasons. These deviations could result in
premiums or discounts to the Fund’s NAV that may be greater than those experienced by other funds.
Non-U.S. Securities Risk. Securities issued by non-U.S. issuers (including depositary receipts) are subject to different legal, regulatory, political, economic, and market risks than
securities issued by U.S. issuers. These risks include greater market volatility, less market liquidity,
higher transaction costs, expropriation, confiscatory taxation, adverse changes in foreign investment or
currency control regulations, restrictions on the repatriation of capital, and political instability. Non-U.S. issuers may be subject to different accounting, audit and financial reporting standards than U.S. issuers, and there may be less
publicly available information about non-U.S. issuers. Foreign market trading hours, different clearing and
settlement procedures, and holiday schedules may limit the Fund's ability to engage in portfolio
transactions. To the extent that investments are made in a limited number of countries, events in those
countries will have a more significant impact on the Fund. The Fund is specifically exposed to Asian Economic Risk and Central and South American Economic Risk.
Operational Risk. The Fund is exposed to operational risks arising from a number of factors, including, but not limited to, human error, processing and communication errors, errors of the
Fund’s service providers, counterparties or other third parties, failed or inadequate processes and
technology or systems failures. The Fund and BFA seek to reduce these operational risks through controls
and procedures. However, these measures do not
