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 Fund and BlackRock Fund prospectus pages. Read the prospectus carefully before investing.

The fund is actively managed and its characteristics will vary.

Stock values fluctuate in price so the value of your investment can go down depending on market conditions.

International investing involves special risks including, but not limited to currency fluctuations, illiquidity and volatility. These risks may be heightened for investments in emerging markets.

The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material.

Investments in emerging markets may be considered speculative and are more likely to experience hyperinflation and currency devaluations, which adversely affect returns. In addition, many emerging securities markets have lower trading volumes and less liquidity.

Investing in long/short strategies presents the opportunity for significant losses, including the loss of your total investment. Such strategies have the potential for heightened volatility and in general, are not suitable for all investors.

The fund may use derivatives to hedge its investments or to seek to enhance returns. Derivatives entail risks relating to liquidity, leverage and credit that may reduce returns and increase volatility.

The fund may engage in active and frequent trading, resulting in short-term capital gains or losses that could increase an investors tax liability.

Short-selling entails special risks. If the fund makes short sales in securities that increase in value, the fund will lose value. Any loss on short positions may or may not be offset by investing short-sale proceeds in other investments.

Performance results reflect past performance and are no guarantee of future results. Investment return and principal value of shares will fluctuate so that shares, when redeemed, may be worth more or less than their original cost. All returns assume reinvestment of all dividends. Performance information shown without sales charge would have been lower if the applicable sales charge had been included. Performance during periods of exceptional market conditions should not be expected to be repeated in a normal market environment. Current performance may be lower or higher than the performance data quoted.

Investing involves risk, including possible loss of principal.

Fund details, holdings and characteristics are as of the date noted and subject to change.

Yields are based on income earned for the period cited and on the Fund's NAV at the end of the period.

Some BlackRock funds make distributions of ordinary income and capital gains at calendar year end. Those distributions temporarily cause extraordinarily high yields. There is no assurance that a fund will repeat that yield in the future. Subsequent monthly distributions that do not include ordinary income or capital gains in the form of dividends will likely be lower.

The Funds are distributed by BlackRock Investments, LLC (together with its affiliates, “BlackRock”).
