Index Snapshot:

The Vanguard Extended Duration Treasury ETF (Ticker: EDV) seeks investment results that correspond generally to the performance, before fees and expenses, of the Lehman Brothers Treasury STRIPS 20–30 Year Equal Par Bond Index. This Index passively selects zero-coupon U.S. Treasury securities (Treasury STRIPS) with maturities ranging from 20 to 30 years. A Treasury STRIP is a single coupon or principal payment from a U.S. Treasury security that has been “stripped” into separately tradable components. All Treasury STRIPS within this Index are assigned an equal weighting and rebalanced quarterly.
