Credit quality ratings on underlying securities of the fund are received from S&P, Moody’s and Fitch and converted to the equivalent S&P major rating category. This breakdown is provided by BlackRock and takes the median rating of the three agencies when all three agencies rate a security the lower of the two ratings if only two agencies rate a security and one rating if that is all that is provided. Unrated securities do not necessarily indicate low quality. Below investment-grade is represented by a rating of BB and below. Ratings and portfolio credit quality may change over time.

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 Fund prospectus pages. Read the prospectus carefully before investing.

Investing involves risk, including possible loss of principal.

The iShares Enhanced ETFs, iShares Short Maturity Bond ETF, iShares Liquidity Income ETF and the iShares Interest Rate Hedged ETFs are actively managed funds and do not seek to replicate the performance of a specified index. The Funds may have a higher portfolio turnover than funds that seek to replicate the performance of an index.



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.

Non-investment-grade debt securities (high-yield/junk bonds) may be subject to greater market fluctuations, risk of default or loss of income and principal than higher-rated securities.

An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency and its return and yield will fluctuate with market conditions.

The iShares Short Maturity Bond ETF will invest in privately issued securities that have not been registered under the Securities Act of 1933 and as a result are subject to legal restrictions on resale. Privately issued securities are not traded on established markets and may be illiquid, difficult to value and subject to wide fluctuations in value. Delay or difficulty in selling such securities may result in a loss to the iShares Short Maturity Bond ETF. The fund may invest in asset-backed (“ABS”) and mortgage-backed securities (“MBS”) which are subject to credit, prepayment and extension risk, and react differently to changes in interest rates than other bonds. Small movements in interest rates may quickly reduce the value of certain ABS and MBS.

Performance shown reflects fee waivers and/or expense reimbursements by the investment advisor to the fund for some or all of the periods shown. Performance would have been lower without such waivers.

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.

Understanding Investments in the Mortgage Market: TBAs and Cash Collateral: TBA (To Be Announced) contracts are standardized contracts for future delivery, in which the exact mortgage pools to be delivered are not specified until a few days prior to settlement. These forward contracts typically represent the most liquid portion of the mortgage market. They are derived from new mortgage pools with specific delivery dates and coupons but without specific pool numbers and number of pools. These forward contracts are fully collateralized. The collateral may be invested in short term instruments. The extent of a portfolio's investment in such short term instruments would be proportionate to its investment in TBAs.
