Investment objective
This Fund seeks a high level of current income;
Principal investment strategy
This Fund invests principally in income producing debt instruments. Under normal circumstances, the Fund will invest at least 60% of its assets in investment grade debt instruments, including corporate debt securities, asset-backed securities, mortgage-related securities, U.S. government securities and agency securities. The Fund may invest up to 40% of its assets in non-investment grade (high yield/high risk, sometimes called junk bonds) debt instruments and floating rate senior loans. Debt instruments in which the Fund invests may include those denominated in U.S. dollars and issued by foreign entities in developed markets. The Fund expects to maintain a weighted average duration within two years (plus or minus) of the Bloomberg US Aggregate Bond Index. Duration is often used to measure a bonds sensitivity to interest rates.
The longer a funds duration, the more sensitive it is to interest rate risk . The shorter a funds duration, the less sensitive it is to interest rate risk . As of December 31, 2025, the duration of the Bloomberg US Aggregate Bond Index was 5.94 years, and the duration of the Fund was 6.00 years. Fundamental Research Process. Individual investment selection is based on the sub-advisers fundamental research process. The sub-advisers fundamental research process combines a bottom-up issuer analysis and top-down market assessment. A bottom-up issuer analysis relies upon the sub-advisers fundamental research analysis of individual issuers. A top-down market assessment provides a framework for portfolio risk positioning and sector allocations. Once this is determined, the sub-adviser looks for companies that it believes have sustainable competitive positions, strong management teams and the ability to repay or refinance its debt obligations.
The sub-adviser performs a credit analysis on each potential issuer and a relative value analysis for each potential investment. When selecting investments, the sub-adviser may invest in instruments that it believes have the potential for capital appreciation. An investment is generally sold when the sub-adviser believes that the issue has realized its price appreciation target, the issue no longer offers relative value, or an adverse change in corporate or sector fundamentals has occurred. The Fund may lend its portfolio holdings to certain financial institutions.
