| Factors Affecting Performance [Text Block] | What drove fund performance during the past 12 months? The U.S. investment-grade fixed income market generated positive results for the 12-month reporting period. Although U.S. Treasury yields generally moved higher, bond investors benefited from higher coupon payments as well as tighter credit spreads amid a resilient economy. Non-benchmark exposure to high yield corporates and bank loans added value relative to the Bloomberg U.S. Aggregate Bond Index. Resilient risk appetite, strong demand for yield, and a supportive fundamental backdrop helped these sectors perform well over the past 12 months. Underweighting U.S. Treasuries also helped as they underperformed other parts of the market. While our corporate bond holdings performed well, underweighting investment-grade corporate bonds weighed on relative performance versus the index as high-grade corporate bonds also generated strong returns. Security selection within agency mortgage-backed securities (MBS) was another headwind. The fund invests in a diversified portfolio of bonds and other debt instruments and is constructed with an aim of being able to respond to a wide variety of market conditions. Over the past 12 months, the fund trimmed its allocation in agency MBS on strength after the sector outperformed in late 2023. As global economic growth improved and financial conditions loosened, we increased the funds total exposure to credit risk over the 12-month period. Overall, the fund held material exposure to derivatives, specifically interest rate derivatives that help the investment team more efficiently manage duration and positioning along the yield curve. The use of derivatives, including interest rate derivatives, had a negative effect on absolute returns. | |
