3. Risk Factors (continued):
and may have their investments in relatively few properties, or in a small geographic area or a single property type. Failure of a company to qualify as a REIT under federal tax law may have adverse consequences to the fund. In addition, REITs have their own expenses, and the fund will bear a proportionate share of those expenses.
Real Estate Investment Risk. Due to the composition of the index, the fund concentrates 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 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.
Tracking Error Risk. As an index fund, the fund seeks to track the performance of its benchmark index, although it may not be successful in doing so. The divergence between the performance of the fund and its benchmark index, positive or negative, is called “tracking error.” Tracking error can be caused by many factors and it may be significant.
Derivatives Risk. The principal types of derivatives used by the fund are futures contracts. A futures contract is an agreement to buy or sell a financial instrument at a specific price on a specific day. 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. Certain of these risks, such as leverage risk, market risk and liquidity risk, are discussed elsewhere.
The fund’s use of derivatives is also subject to credit risk, lack-of-availability risk, valuation risk, correlation risk and tax risk. Credit risk is the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations. Lack-of-availability risk is the risk that suitable derivative transactions may not be available in all circumstances for risk management or other purposes. Valuation risk is the risk that a particular derivative may be valued incorrectly. Correlation risk is the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Tax risk is the risk that the use of derivatives may cause the fund to realize higher amounts of short-term capital gain. The fund’s use of derivatives could reduce the fund’s performance, increase the fund’s volatility, and cause the fund to lose more than the initial amount invested. The fund's use of derivatives that are subject to regulation by the Commodity Futures Trading Commission (CFTC) could cause the fund to become a commodity pool, which would require the fund to comply with certain CFTC rules.
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 (including the real estate industry, as described above), the fund may be adversely affected by the performance of those securities, may be subject to increased price volatility and may be more susceptible to adverse economic, market, political or regulatory occurrences affecting that market, industry, group of industries, sector or asset class.
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.
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.
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 NAV, there may be times when the market price and the NAV vary significantly. Investors may pay more than NAV when they buy shares of the fund in the secondary market, and may receive less than NAV when they sell those shares in the secondary market. The market price of the fund shares may deviate, sometimes significantly, from NAV during periods of market volatility.
