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-Diversification Risk. The Fund is classified as
“non-diversified.”
This means that, compared with funds that are classified as “diversified,” the Fund may invest a greater percentage of its assets in securities or other instruments representing a small number of issuers or counterparties and thus may be more susceptible to the risks associated with
these particular issuers or counterparties. As a result, the Fund's performance may depend to a greater
extent on the performance of a small number of issuers or counterparties, which may lead to more volatility
in the Fund’s NAV.
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 address every
possible risk and may be inadequate to address significant operational risks.
Reliance on Trading Partners
Risk. The Fund invests in a country whose economy is heavily dependent upon trading with key partners. Any reduction in this trading may have an adverse
impact on the Fund's investments. Through its holdings of securities of certain issuers, the Fund is
specifically exposed to Asian Economic Risk, Central and South American Economic Risk and U.S. Economic
Risk.
Risk of Investing in Emerging Markets. Investments in Brazil may be subject to a greater risk of loss than investments in issuers located or operating in more developed markets. Emerging markets may be more likely to experience inflation,
social instability, political turmoil or rapid changes in economic conditions than more developed markets.
Companies in many emerging markets are not subject to the same degree of regulatory requirements,
accounting standards or auditor oversight as companies in more developed countries, and as a result,
information about the securities in which the Fund invests may be less reliable or complete. Emerging markets often have less reliable securities valuations and greater risk associated with custody of securities than developed markets. There
may be significant obstacles to obtaining information necessary for investigations into or litigation
against companies and shareholders may have limited legal remedies. The Fund does not select investments
based on investor protection considerations.
Tracking Error Risk. The Fund may be subject to “tracking
error,”
which is the divergence of the Fund’s performance from that of the Underlying Index. Tracking error
may occur due to a number of factors, including differences between the securities and other assets held in
the Fund’s portfolio and those included in the
