The fund primarily invests in interest-only mortgage-backed securities (MBS IOs) and U.S. Treasury bonds. The allocation between these two asset classes is actively managed and fluctuates based on several criteria. These criteria include relative value assessments, which consider historical yield levels compared to other financial instruments, market volatility, and other risk metrics identified by the sub-adviser. Macroeconomic factors like inflation and economic growth, along with any other pertinent elements deemed relevant by the sub-adviser, also inform these adjustments. This fund is categorized as non-diversified.
