- American Century Ginnie Mae Investor Class (BGNMX) is an open-end mutual fund managed by American Century Investments that seeks high current income while maintaining liquidity and safety of principal by investing primarily in Government National Mortgage Association (GNMA) certificates; these securities represent interests in pools of mortgage loans and their cash flows, with the fund committing at least 80% of net assets to GNMA-issued mortgage-backed securities, including agency mortgage-backed bonds averaging AAA credit quality and moderate interest-rate sensitivity. To generate additional income, the fund engages in when-issued and forward commitment transactions, such as mortgage dollar rolls, with up to 35% of total assets allocated to these strategies; its portfolio is diversified across US bonds (approximately 88-93%), cash equivalents (around 12%), and minimal exposure to government-related securities, benchmarked against the Bloomberg U.S. GNMA Index. The Investor Class shares feature a net expense ratio of 0.55%, no front-end or deferred loads, a minimum initial investment of $2,500 ($1,000 for IRAs), and daily pricing, targeting individual and institutional investors in the United States within the intermediate government or government mortgage-backed bond category.
Launched on September 23, 1985, as part of American Century Government Income Trust and formerly known as Benham Government Income Trust - Ginnie Mae Fund, the fund is domiciled in the United States with headquarters aligned to American Century Investments in Kansas City, Missouri; it operates exclusively in US fixed-income markets, holding approximately 162 securities with top holdings including GNMA pass-throughs at various coupons such as 2%, 2.5%, 3%, 5%, 5.5%, and 6.5%, comprising 23-37% of the portfolio in the top five to ten positions.
Recent portfolio management changes include Michael Waggaman and Curtis Manning joining as co-managers on August 1, 2022, followed by Paul Norris on November 10, 2023, reflecting a strategic enhancement to the team's fixed-income expertise amid evolving interest rate environments; the fund has maintained stable operations with no reported acquisitions, partnerships, funding rounds, or major reorganizations specific to BGNMX in the last 1-2 years, though American Century Investments continues to emphasize active management in GNMA securities. As of late 2025, total net assets stand at approximately $362-403 million, with a turnover ratio of 68% and a 12-month yield around 3.4-3.8%, underscoring its focus on high-quality, liquid government-backed investments without significant strategic shifts.
