Bond Statistic Average Coupon: The average coupon is the weighted average coupon rate of all the bonds in the fund.
Bond Statistic Average Duration in Years: Expressed in years, average duration is a weighted average of the estimated price sensitivity of the bonds in the fund's portfolio to a given change in interest rates. With respect to individual bonds, for example, a duration of 4 years indicates that the price of a bond will rise/fall by approximately 4% if rates in general fall/rise by 1%. Typically, bonds with a longer duration pay higher interest but are more sensitive to interest rate changes.
Bond Statistic Average Life in Years: Expressed in years, average life is time weighting the expected principal payments, taking into consideration the impact of calls and prepayments. In general, it is a better measure than average maturity for bonds that have the ability to prepay principal before they reach maturity (e.g., mortgages, mortgage-backed securities and asset-backed securities). Data shown is a weighted average of the bond funds held in the fund's portfolio.
Bond Statistic Average Yield to Maturity: A weighted average of all the fund's bond holding's yield to maturities. Yield to maturity is the return a bond earns if held to maturity, based on its price and coupon. Assumes that coupon payments can be reinvested at the yield to maturity.
