The fund invests at least 80% of its assets in a diverse mix of mortgage-backed securities, including those issued or guaranteed by U.S. government agencies such as the Federal Home Loan Mortgage Corporation, Federal National Mortgage Association, and Government National Mortgage Association. These investments help the fund maintain a high credit quality and a moderate sensitivity to interest rates.

With regular monthly dividends and a competitively low expense ratio, the fund appeals to investors seeking stable income.
