Vanguard Core Bond 

This actively managed fund seeks to provide broadly diversified exposure predominantly to the U.S. investment-grade bond market. The low-cost fund invests in U.S. Treasury, mortgage-backed, and corporate securities of varying yields and maturities (short-, intermediate-, and long-term issues). Using a disciplined, risk-controlled approach, the fund seeks to outperform the broad investment-grade market through security selection, sector allocation, and, to a lesser extent, duration decisions. Like other bond funds, the fund is subject to interest rate risk; increases in interest rates may cause the price of the bonds in the portfolio to decrease, reducing the fund’s NAV. Since the fund invests in all major segments and maturities of the investment-grade fixed income market, investors may consider the fund as a core bond holding.The Core Bond ETF is a stand alone product and is separate and distinct from the Vanguard Core Bond Fund (VCOBX and VCORX). Differences in scale, certain investment processes, and underlying holdings are expected to produce different investment returns by the funds.
