Investment Strategy The Fund employs sophisticated indexing methods to construct a portfolio that closely matches the characteristics of the Barclays U.S. Aggregate Bond Index (which is comprised of several thousand fixed income securities) without having to own all of the securities in the Index. This Fund invests in U.S. Treasury Securities as well as Government Agency, Investment Grade, Corporate, Residential, Commercial and Asset Backed Security Sectors with an attempt to minimize turnover. Derivatives are used in the form of U.S. Treasury futures contracts. The average maturity of the Fund is typically in excess of six years and duration is typically over four years. The Fund may also generate some income by lending securities to creditworthy financial institutions. There is no guarantee that the Fund's investment objective will be met. Category Description: Intermediate-Term Bond Intermediate-term bond portfolios invest primarily in corporate and other investment-grade U.S. fixed-income issues and typically have durations of 3.5 to 6.0 years. These portfolios are less sensitive to interest rates, and therefore less volatile, than portfolios that have longer durations. Morningstar calculates monthly breakpoints using the effective duration of the Morningstar Core Bond Index in determining duration assignment. Intermediate-term is defined as 75% to 125% of the three-year average effective duration of the MCBI. Volatility Analysis Low Moderate High Investment Category In the past, this investment has shown a relatively small range of price fluctuations relative to other investments. Based on this measure, currently more than two-thirds of all investments in this category have shown higher levels of risk. Consequently, this investment may appeal to investors looking for a conservative investment strategy.
