The fund invests primarily in interest-only mortgage-backed securities (?MBS IOs?) and U.S. Treasury bonds. The allocation ratio between MBS IOs and U.S. Treasuries will vary depending on relative value relationships, including historical yield levels compared to other financial assets, volatility and other risk measures (as determined by the sub-adviser), macro-environment determinants, such as inflation and economic growth, and other factors that the sub-adviser evaluates to be relevant. The fund is non-diversified.
