iShares 0-3 Month Treasury Bond ETF(AMEX:SGOV)

SGOV offers vanilla exposure to ultra-short-maturing fixed income securities of the US Treasury market. The fund is tracking the ICE 0-3 Month US Treasury Securities Index whose components are selected and weighted by market value, and rebalances every month. Securities included in the index are USD-denominated with fixed coupon schedule and have minimum 50 remaining days to final maturity (up to 3-months), while inflation-linked securities, cash management bills and zero-coupon bonds are excluded for the selection. The index does not reinvest coupon payments or maturity proceeds between each rebalance. As a result, the fund may invest up to 10% of its portfolio in money markets as well as in futures, options, swaps and cash-like instrument as advised by its fund manager.
