The fixed-income segment features a diversified mix of high- and medium-grade non-money market debt securities such as U.S. Treasury notes, mortgage-backed securities, and corporate bonds, with an emphasis on investment-grade obligations to mitigate credit and interest rate risks. ABINX, part of the moderate allocation category with an institutional share class featuring a net expense ratio of 0.69% and assets under management exceeding $899 million as of late 2025, targets long-term investors including financial advisors' clients and institutional accounts, with a minimum initial investment waived under certain automatic plans.

Recent developments at American Century include surpassing $300 billion in assets under supervision in September 2025, driven by expansion in active ETFs reaching $75 billion and the 2023 acquisition of the 3x5 Partners venture capital team to enter private markets focused on healthcare and climate investments.
