iShares 1-10 Year Treasury Bond 

GOVM seeks to replicate the performance of an index of fixed-rate US Treasury securities with remaining maturities between one to ten years. The index is market value weighted and rebalanced monthly. The ETF does not attempt to outperform its benchmark but rather aims to deliver consistent index-level returns while keeping portfolio turnover and costs low. The fund is managed using a representative sampling strategy. Performance is tracked before the deduction of fees and expenses. Up to 10% of assets may be allocated to futures, options, and swap contracts to assist in index tracking. The fund may also lend securities of up to one-third of its total assets.
