Carefully consider the Funds' investment objectives, risk factors and charges and expenses before investing. This and other information can be found in the Funds' prospectuses, which may be obtained by calling 1-800-iShares (1-800-474-2737) or click here to view or download a prospectus. Read the prospectus carefully before investing.

Investing involves risk, including possible loss of principal.

‡ “Acquired Fund Fees and Expenses” reflect the Fund's pro rata share of the indirect fees and expenses incurred by investing in one or more acquired funds, such as mutual funds, business development companies, or other pooled investment vehicles. Acquired Fund Fees and Expenses are reflected in the prices of the acquired funds and thus included in the total returns of the Fund.

The iShares Funds ("Funds") are distributed by SEI Investments Distribution Co. (SEI). Barclays Global Fund Advisors (BGFA) serves as the investment advisor to the Funds. BGFA is a subsidiary of Barclays Global Investors, N.A., a majority-owned subsidiary of Barclays Bank PLC, none of which is affiliated with SEI.

Bonds and bond funds will decrease in value as interest rates rise.

Index returns are for illustrative purposes only and do not represent actual iShares performance. Index performance returns do not reflect any management fees, transaction costs or expenses. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results.

A portion of the Fund's income may be subject to federal or state income taxes or the alternative minimum tax. Capital gains, if any, are subject to capital gains tax. Federal or state changes in income or alternative minimum tax rates or in the tax treatment of municipal bonds may make them less attractive as investments and cause them to lose value.

S&P and Standard & Poor's are trademarks of The McGraw-Hill Companies, Inc. and have been licensed for use by Barclays Global Investors, N.A. iShares Funds are not sponsored, endorsed, issued, sold or promoted by Standard & Poor's. Nor does this company make any representation regarding the advisability of investing in iShares Funds. Index data source: Standard & Poors.

Shares of iShares Funds are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns.

Certain sectors and markets perform exceptionally well based on current market conditions and iShares funds can benefit from that performance. Achieving such exceptional returns involves the risk of volatility and investors should not expect that such results will be repeated.
