CGCB seeks to maximize current income while preserving capital by investing primarily in bonds. The fund invests in investment-grade, fixed-income securities issued by corporate and government entities with no specific maturity range. These securities may include bonds, treasuries, mortgage- and asset-backed securities issued by the US government-sponsored entities and other instrumentalities not backed by full faith, money market instruments, cash and cash equivalents, and inflation-linked bonds issued by US and non-US entities. Holdings may also include derivatives such as futures, swaps, and to-be-announced contracts. CGCB is managed by a team of portfolio managers who aim to select attractively priced securities believed to be promising investment opportunities. Positions are sold if they are no longer considered attractive.
