Carefully consider the iShares Funds' investment objectives, risk factors, and charges and expenses before investing.

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.

*BlackRock Fund Advisors, the investment adviser to the iShares S&P Emerging Markets Infrastructure Index Fund, has contractually agreed to waive its management fees in an amount equal to the Acquired Fund Fees and Expenses incurred by the Fund through June 30, 2013.

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.

In addition to the normal risks associated with investing, international investments may involve risk of capital loss from unfavorable fluctuation in currency values, from differences in generally accepted accounting principles or from economic or political instability in other nations.

Emerging markets involve heightened risks related to the same factors as well as increased volatility and lower trading volume.

Narrowly focused investments may be subject to higher volatility.

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.

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.
