30-Day SEC Yield 30-Day SEC Yield

A standard yield calculation developed by the Securities and Exchange Commission that allows for fairer comparisons among bond funds. It is based on the most recent 30-day period. This yield figure reflects the interest earned during the period after deducting the fund's expenses for the period.

For funds holding To-Be-Announced (TBA) contracts, the 30 day SEC yield includes income earned on cash holdings and direct holdings of mortgage pools, net of fund expenses . Certain funds obtain a significant amount of its mortgage market exposure through TBA transactions. Those Funds invest cash pending settlement of any TBA transactions in high-quality, liquid short-term instruments. TBA contracts provide the fund with economic exposure to the mortgage market. The income that they generate is paid out in fund distributions but is not included in the SEC yield calculation. As a result, for funds holding TBA contracts, the SEC yield will generally be below the stated fund distribution yield.

12-Month Yield 12-Month Yield

The 12-Month yield is calculated by summing any income distributions over the past twelve months and dividing by the sum of the most recent NAV and any capital gain distributions made over the past twelve months.

Carefully consider the iShares Funds' investment objectives, risk factors, and charges and expenses before investing. This and other information can be found in the Funds' prospectuses, which may be obtained by calling 1-800-iShares (1-800-474-2737), or by viewing or downloading a prospectus. Read the prospectus carefully before investing.

Investing involves risk, including possible loss of principal.

Certain iShares funds are subject to management fee breakpoints as assets increase. The breakpoints take effect immediately after asset tier levels are reached, thus a fund's actual management fee being applied may not match the fund's web site or prospectus on a given day.

‡ “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.

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

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. Indexes are unmanaged and one cannot invest directly in an index. Past performance does not guarantee future results.
