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.

Fund of funds are subject to the risks associated with the underlying BlackRock funds in which it invests.

Stock and bond 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.

Fixed income risks include interest-rate and credit risk. Typically, when interest rates rise, there is a corresponding decline in bond values. Credit risk refers to the possibility that the bond issuer will not be able to make principal and interest payments.

Asset allocation strategies do not assure profit and do not protect against loss.

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 target date in the funds name is the approximate date an investor plans to start withdrawing money. The principal value is not guaranteed at any time, including at the target date.

‡Morningstar Analyst Rating™is not a credit or risk rating. It is a subjective evaluation performed by Morningstar’s manager research group, which consists of various Morningstar, Inc. subsidiaries (“Manager Research Group”). In the United States, that subsidiary is Morningstar Research Services LLC, which is registered with and governed by the U.S. Securities and Exchange Commission. The Manager Research Group evaluates funds based on five key pillars, which are process, performance, people, parent, and price. The Manager Research Group uses this five pillar evaluation to determine how they believe funds are likely to perform relative to a benchmark, or in the case of exchange-traded funds and index mutual funds, a relevant peer group, over the long term on a risk-adjusted basis. They consider quantitative and qualitative factors in their research, and the weight of each pillar may vary. The Analyst Rating scale is Gold, Silver, Bronze, Neutral, and Negative. A Morningstar Analyst Rating of Gold, Silver, or Bronze reflects the Manager Research Group’s conviction in a fund’s prospects for outperformance. Analyst Ratings ultimately reflect the Manager Research Group’s overall assessment, are overseen by an Analyst Rating Committee, and are continuously monitored and reevaluated at least every 14 months. For more detailed information about Morningstar’s Analyst Rating, including its methodology, please go to global.morningstar.com/managerdisclosures/.

The Morningstar Analyst Rating (i) should not be used as the sole basis in evaluating a fund, (ii) involves unknown risks and uncertainties which may cause Analyst expectations not to occur or to differ significantly from what they expected, and (iii) should not be considered an offer or solicitation to buy or sell the fund.

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.

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.
