iShares U.S. Treasury Bond ETF GOVT Strategy

The investment seeks to track the investment results of the ICE U.S. Treasury Core Bond Index (the "underlying index"). The fund will invest at least 80% of its assets in the component securities of the underlying index and will invest at least 90% of its assets in U.S. Treasury securities that BFA believes will help the fund track the underlying index. The underlying index includes publicly-issued U.S. Treasury securities that have a remaining maturity greater than one year and less than or equal to thirty years and have $300 million or more of outstanding face value.
