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 or, if available, the summary prospectuses which may be obtained by visiting the iShares ETF and BlackRock Mutual Fund prospectus pages. Read the prospectus carefully before investing.

Investing involves risk, including possible loss of principal.

Funds that concentrate investments in a single sector will be more susceptible to factors affecting that sector and more volatile than funds that invest in many different sectors.

Shares of ETFs are bought and sold at market price (not NAV) and are not individually redeemed from the Fund. Brokerage commissions will reduce returns. Market returns are based upon the midpoint of the bid/ask spread at 4:00 p.m. eastern time (when NAV is normally determined for most ETFs), and do not represent the returns you would receive if you traded shares at other times.

Index returns are for illustrative purposes only. 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.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor's tax situation and may differ from those shown. The after-tax returns shown are not relevant to investors who hold their fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

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.

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. The document discusses exchange traded options issued by The Options Clearing Corporation and is intended for educational purposes. No statement in the document should be construed as a recommendation to buy or sell a security or to provide investment advice. If you need further information, please feel free to call the Options Industry Council Helpline. They will be able to provide you with balanced options education and tools to assist you with your iShares options questions and trading. The Options Industry Council Helpline phone number is 1-888-Options (1-888-678-4667) and their website is www.888options.com.
