Carefully consider the iShares 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 by viewing or downloading 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"). BlackRock Fund Advisors ("BFA") serves as the investment advisor to the Funds. BFA is a subsidiary of BlackRock Institutional Trust Company, N.A., neither of which is affiliated with SEI.

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.

Options involve risk and are not suitable for all investors. Prior to buying or selling an option, a person must receive a copy of Characteristics and Risks of Standardized Options. Copies of this document may be obtained from your broker, from any exchange on which options are traded or by contacting The Options Clearing Corporation, One North Wacker Dr., Suite 500, Chicago, IL 60606 (1-888-678-4667). The document contains information on options issued by The Options Clearing Corporation.

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.
