The fund's primary objective is to achieve an annual total return that surpasses the performance of the Bloomberg U.S. Aggregate Bond Index, prior to accounting for its operational expenses. To meet this goal, it customarily allocates a minimum of 80% of its overall assets to a diverse range of U.S. dollar-denominated fixed-income instruments. These investments encompass obligations from the U.S. government and its public-sector agencies, securitized products such as asset-backed and mortgage-backed securities issued by both domestic and international entities, and corporate bonds originating from companies based in the U.S. and abroad.
