Fund Description

The Fund seeks to track the investment results of the ICE AMT-Free US National Municipal Index (the “Underlying Index”), which measures the performance of U.S. dollar denominated investment grade tax-exempt debt publicly issued in the U.S. domestic market by U.S. states and their political subdivisions. As of February 29, 2024, there were 23,383 issues in the Underlying Index. As of February 29, 2024, a significant portion of the Underlying Index is represented by municipal bonds. The components of the Underlying Index are likely to change over time.
The Underlying Index includes municipal bonds, the interest of which is exempt from Federal income taxes and not subject to alternative minimum tax. Each bond in the Underlying Index must have a rating of at least BBB- by Standard & Poor’s® Global Ratings, a subsidiary of S&P Global, Baa3 by Moody’s Investors Service, Inc., or BBB- by Fitch Ratings, Inc. A bond must be rated by at least one of these three rating agencies in order to qualify for the Underlying Index, and the lowest rating will be used in determining if the bond is investment grade. Each bond in the Underlying Index must be a constituent of an offering where the original offering amount was at least $100 million and have a minimum par amount (i.e., currently outstanding face value) of $15 million. In addition, each bond must have a minimum remaining term to final maturity greater than or equal to one calendar month to be included in the Underlying Index. The Underlying Index is a market-value weighted index and is subject to a capping methodology that aims at reducing index concentration. The Underlying Index is rebalanced on the last calendar day of the month.
BFA uses an indexing approach to try to achieve the Fund’s investment objective. Unlike many investment
companies, the Fund does not try to “beat” the index it tracks and does not seek temporary defensive positions when markets decline or appear overvalued.
Indexing may eliminate the chance that the Fund will substantially outperform the Underlying Index but also may reduce some of the risks of active management, such as poor security selection. Indexing seeks to achieve lower costs and better after-tax performance by aiming to keep portfolio turnover low in comparison to actively managed investment companies.
BFA uses a representative sampling indexing strategy to manage the Fund. “Representative sampling” is an indexing strategy that involves investing in a representative sample of securities that collectively has an investment profile similar to that of an applicable underlying index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration (i.e., a security's price sensitivity to a change in interest rates), maturity or credit ratings and yield) and liquidity measures similar to those of an applicable underlying index. The Fund may or may not hold all of the securities in the Underlying Index.
The Fund will invest at least 80% of its assets in the component securities of the Underlying Index, and the Fund will invest at least 90% of its assets in fixed income securities of the types included in the Underlying Index that BFA believes will help the Fund track the Underlying Index. The Fund will invest no more than 10% of its assets in futures, options and swaps contracts
that BFA believes will help the Fund track the Underlying Index as well as in fixed income securities other than the types included in the Underlying Index, but which BFA believes will help the Fund track the Underlying Index. Cash and cash equivalent investments associated with a derivative position will be treated as part of that position for the purposes of calculating the percentage of investments included in the Underlying Index. The Fund will generally hold municipal bond securities issued by state and local municipalities whose interest payments are exempt from U.S. federal income taxes and the federal alternative minimum tax “AMT”). As of the date of this Prospectus, interest that is exempt from U.S. federal income tax is also exempt from the federal Medicare contribution tax of 3.8% on “net investment income.”In addition, the Fund intends to invest any cash assets in one or more affiliated municipal money market funds, which may be advised by BFA or its affiliates. The Fund seeks to track the investment results of the Underlying Index before fees and expenses of the Fund.
The Fund may invest in shares of other iShares funds that provide substantially similar exposure to the securities in the Underlying Index. BFA will waive a portion of its management fees in an amount equal to the acquired fund fees and expenses, if any, attributable to the Fund's investment in other iShares funds.
The Underlying Index is sponsored by ICE Data Indices, LLC (the “Index Provider” or “IDI”), which is independent of the Fund and BFA. The Index Provider determines the composition and relative weightings of the securities in the Underlying Index and publishes
information regarding the market value of the Underlying Index.
Industry Concentration Policy. The Fund will concentrate its investments i.e., hold 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities), repurchase agreements collateralized by U.S. government securities, and securities of state or municipal governments and their political subdivisions are not considered to be issued by members of any industry.
