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.

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.

The  iShares® iBonds® ETFs ("Funds") will terminate on or about December 31 of the year in each Fund’s name. An investment in the Fund(s) is not guaranteed, and an investor may experience losses, including near or at the termination date. Unlike a direct investment in a bond that has a level coupon payment and a fixed payment at maturity, the Fund(s) will make distributions of income that vary over time. In the final months of each Fund’s operation, as the bonds it holds mature, its portfolio will transition to cash and cash-like instruments. As a result, its yield will tend to move toward prevailing money market rates, and may be lower than the yields of the bonds previously held by the Fund and lower than prevailing yields in the bond market.

Following the Fund’s termination date, the Fund will distribute substantially all of its net assets, after deduction of any liabilities, to then-current investors without further notice and will no longer be listed or traded. The Funds’ distributions and liquidation proceeds are not predictable at the time of investment and the Funds do not seek to return any predetermined amount.

The rate of Fund distribution payments may adversely affect the tax characterization of an investor’s returns from an investment in the Fund relative to a direct investment in bonds. If the amount an investor receives as liquidation proceeds upon the Fund’s termination is higher or lower than the investor’s cost basis, the investor may experience a gain or loss for tax purposes.

Investment in the iShares® iBonds® Corporate ETFs is subject to the risks of the other funds and ETFs (underlying funds) in which it invests. The iShares® iBonds® Corporate ETFs will incur acquired fund fees and expenses associated with its investments the underlying funds and additional fees associated with turnover in the underlying funds that are not included in the acquired fund fees and expenses.

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.
