Its central objective is to achieve a total return with a particular emphasis on generating current income, while also considering opportunities for capital appreciation. The fund allocates at least 80% of its assets to a diversified portfolio of high-quality bonds, including U.S. government securities, corporate bonds, and securitized instruments such as mortgage- or asset-backed securities. Employing an actively managed approach, the fund’s investment process integrates macroeconomic analysis with bottom-up security selection and technical market insights, aiming to manage risk and enhance value through strategic asset allocation, duration, and yield curve positioning. Portfolio managers collaborate closely with analysts to set risk budgets and identify appropriate investments, ensuring a comprehensive risk-management framework. Class R4 shares of this fund are typically available to eligible retirement plans and institutional investors. With a competitive net expense ratio, the fund seeks to balance income generation and principal stability, making it a core holding for investors requiring broad exposure to the U.S. investment-grade bond market. The fund’s performance is benchmarked against the Bloomberg U.S. Aggregate Bond Index, a widely recognized standard for the domestic fixed income market.
