Investment Style Risk — The fund is an index fund. Therefore, the fund follows the securities included in the index during upturns as well as downturns. Because of its indexing strategy, the fund does not take steps to reduce market exposure or to lessen the effects of a declining market. In addition, because of the fund’s expenses, the fund’s performance may be below that of the index. Errors relating to the index may occur from time to time and may not be identified by the index provider for a period of time. In addition, market disruptions could cause delays in the index’s rebalancing schedule. Such errors and/or market disruptions may result in losses for the fund.

Market Capitalization Risk — Securities issued by companies of different market capitalizations tend to go in and out of favor based on market and economic conditions. During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Mid-Cap Company Risk — Mid-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and the value of securities issued by these companies may move sharply.

Sampling Index Tracking Risk — The fund may not fully replicate the index and may hold securities not included in the index. As a result, the fund is subject to the risk that the investment adviser’s investment management strategy, the implementation of which is subject to a number of constraints, may not produce the intended results. Because the fund utilizes a sampling approach it may not track the return of the index as well as it would if the fund purchased all of the securities in the index.

Derivatives Risk — The fund’s use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and could cause the fund to lose more than the initial amount invested. In addition, investments in derivatives may involve leverage, which means a small percentage of assets invested in derivatives can have a disproportionately large impact on the fund.

Securities Lending Risk — Securities lending involves the risk of loss of rights in, or delay in recovery of, the loaned securities if the borrower fails to return the security loaned or becomes insolvent.

Market Trading Risk — Although fund shares are listed on national securities exchanges, there can be no assurance that an active trading market for fund shares will develop or be maintained. If an active market is not maintained, investors may find it difficult to buy or sell fund shares.

During a period when securities of a particular market capitalization fall behind other types of investments, the fund’s performance could be impacted.

Tracking Error and Correlation Risk — As an index fund, the fund seeks to track the performance of the index, although it may not be successful in doing so. Further, there can be no guarantee that the fund will achieve a high degree of correlation between the fund’s performance and that of its index. The correlation between the performance of the fund and that of its index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant.

Liquidity Risk — The fund may be unable to sell certain securities, such as illiquid securities, readily at a favorable time or price, or the fund may have to sell them at a loss.

Concentration Risk — To the extent that the fund’s or the index’s portfolio is concentrated in the securities of issuers in a particular market, industry, group of industries, sector, or asset class, the fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more vulnerable to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector, or asset class.

Shares of the Fund May Trade at Prices Other Than NAV — Fund shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the shares of the fund will approximate the fund’s net asset value (NAV), there may be times when the market price and the NAV vary significantly. An investor may pay more than NAV when buying shares of the fund in the secondary market, and an investor may receive less than NAV when selling those shares in the secondary market. The market price of fund shares may deviate, sometimes significantly, from NAV during periods of market volatility or market disruption.

Therefore, the fund follows the securities included in the index, which may include real estate investment trusts, during upturns as well as downturns.

Foreign Investment Risk — The fund’s investments in securities of foreign issuers involve certain risks that may be greater than those associated with investments in securities of U.S. issuers. These include risks of adverse changes in foreign economic, political, regulatory and other conditions; changes in currency exchange rates or exchange control regulations (including limitations on currency movements and exchanges); the imposition of economic sanctions or other government restrictions; differing accounting, auditing, financial reporting and legal standards and practices; differing securities market structures; and higher transaction costs. These risks may negatively impact the value or liquidity of the fund’s investments and could impair the fund’s ability to meet its investment objective or invest in accordance with its investment strategy. There is a risk that investments in securities denominated in, and/or receiving revenues in, foreign currencies will decline in value relative to the U.S. dollar. Foreign securities also include ADRs, GDRs, and EDRs, which may be less liquid than the underlying shares in their primary trading market, and GDRs, in particular, many of which are issued by companies in emerging markets, may be more volatile.To the extent the fund’s investments in a single country or a limited number of countries represent a large percentage of the fund’s assets, the fund’s performance may be adversely affected by the economic, political, regulatory, and social conditions in those countries, and the fund’s price may be more volatile than the price of a fund that is geographically diversified.

Mid-Cap Company Risk — Mid-cap companies may be more vulnerable to adverse business or economic events than larger, more established companies and the value of securities issued by these companies may move sharply.

Real Estate Investment Risk — Due to the composition of the index, the fund will concentrate its investments in real estate companies and companies related to the real estate industry. As such, the fund is subject to risks associated with the direct ownership of real estate securities and an investment in the fund will be closely linked to the performance of the real estate markets. These risks include, among others: declines in the value of (or income generated by) real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds or other limits to accessing the credit or capital markets; defaults by borrowers or tenants, particularly during an economic downturn; and changes in interest rates.
