Fund Description

Vanguard Total Bond Market Index Fund, Investor Shares was incepted in December 1986 and is managed by The Vanguard Group. The objective of this fund is to seek a high level of interest income. The fund attempts to match the performance of the unmanaged Lehman Brothers Aggregate Bond Index, which is a widely recognized measure of the entire taxable U.S. bond market. The index consists of more than 5,000 U.S. Treasury, federal agency, mortgage-backed, and high-quality corporate securities, with a total market value exceeding $4 trillion. Since it is not cost effective to own every security in the index, the fund invests in a large sample that matches key characteristics of the index (such as market-sector weightings, coupon interest rates, credit quality, and maturity). To boost returns, the fund holds a higher percentage than the index in high-quality, short-term corporate bonds and a lower percentage in short-term treasury securities. The fund declares dividends on daily basis and distributes on the first business day of each month. Capital gains are distributed annually in December.
