- Core Bond Fund
Fund Objective
The bond fund seeks to generate a high level of current income, consistent with the prudent limitation of investment risk.
Investment Strategies
The fund invests at least 80% of its assets in bonds. To keep current income relatively stable and to limit share price volatility, the Fund emphasizes investment grade securities and maintains an intermediate (typically 3-6 year) average portfolio duration. In addition to U.S. Government and Corporate debt securities the fund may also invest in asset-backed and mortgage-backed securities, as well as non-rated debt securities.
