Investment Objective & Strategy   The investment seeks a high level of income by investing in non-money market debt securities. Under normal market conditions, the fund invests at least 80% of its net assets in high- and medium-grade, non-money market debt securities. It invests most of its assets in investment-grade securities. The weighted average maturity of the fund's portfolio must be three and one-half years or longer.

Morningstar Category: Intermediate Core Bond Intermediate-term core bond portfolios invest primarily in investment-grade U.S. fixed-income issues including government, corporate, and securitized debt, and hold less than 5% in below-investment-grade exposures. Their durations (a measure of interest-rate sensitivity) typically range between 75% and 125% of the three-year average of the effective duration of the Morningstar Core Bond Index.
