OneAmerica Financial Partners is an Indianapolis-based mutual holding company with a 149-year operating history and an A+ AM Best rating that has been maintained for 74 consecutive years. Only about 8% of U.S. life insurers hold both A+ (AM Best) and AA- (S&P) ratings simultaneously – OneAmerica is in that group. Their product line centers on fixed indexed annuities, deferred income annuities, and group retirement solutions distributed through independent financial professionals. If financial strength and carrier stability are among your top criteria, OneAmerica belongs on your shortlist.

OneAmerica’s Financial Strength and Background
OneAmerica traces its roots to 1877, when it was organized under the fraternal insurance model. The company reorganized through a series of mergers in the 20th century, ultimately becoming OneAmerica Financial Partners in 2000. Today it operates as a mutual holding company – policyholders own the organization, and there are no shareholders seeking quarterly returns.
The financial profile is exceptional. AM Best has rated OneAmerica’s primary issuing entities at A+ (Superior) for 74 consecutive years. The combination of A+ (AM Best) and AA- (S&P) is held by fewer than 8% of U.S. life insurers. Verify current ratings at ambest.com and oneamerica.com.
OneAmerica distributes annuity products primarily through independent financial advisors and general agents rather than a career agent force. This means their products are accessible through independent planners and advisors who can compare them against other carriers – though OneAmerica is not as broadly available through IMO aggregator platforms as some competitors.
What Annuity Products Does OneAmerica Offer?
- Freedom Builder Fixed Indexed Annuity – Growth-oriented FIA linked to market indexes with downside protection. Optional income riders available. Designed for accumulation-phase buyers who want index-linked growth potential without direct market exposure.
- Secure Income Stream Deferred Income Annuity (DIA) – Guaranteed income starting at a future date. Buyers deposit a premium today and receive guaranteed payments beginning at a specified age, typically 5-30 years later. Useful for building a future income floor. $10,000 minimum.
- Fixed Deferred Annuities – Guaranteed rate options for specified terms (1, 3, and 5 years available through the Secure5 and similar products). Principal protection with predictable growth.
- Group Retirement Annuities – OneAmerica has a long-established group retirement business serving employers with 401(k), 403(b), and pension solutions through American United Life Insurance Company.

Who Is OneAmerica Best For?
- Buyers for whom financial strength and mutual ownership are top criteria – A+ rated, mutual structure, 149-year history, and 74 consecutive years at A or better is a combination few carriers can match.
- Pre-retirees building a future income floor with a DIA – the Secure Income Stream deferred income annuity lets buyers lock in future income today at younger ages, often at better rates than waiting.
- FIA buyers who want index-linked growth with downside protection from a carrier with exceptional financial stability.
- Buyers working with independent financial advisors in the Midwest and nationally who have access to the OneAmerica product shelf.
OneAmerica is not the best fit for buyers comparing MYGA rates on aggregator platforms (they are not as widely distributed as carriers like Athene or American Equity), or buyers seeking the highest available crediting rates above all other factors.

Frequently Asked Questions About OneAmerica Financial
What is the difference between OneAmerica and American United Life?
American United Life Insurance Company (AUL) is the primary issuing entity – the actual insurance company that backs your policy. OneAmerica Financial Partners is the intermediate holding company above AUL. The mutual holding company above OneAmerica is American United Mutual Insurance Holding Company. When you purchase an annuity, your contract is issued by AUL or State Life Insurance Company (another OneAmerica subsidiary), both rated A+ by AM Best.
What is a deferred income annuity and how does OneAmerica’s Secure Income Stream work?
A deferred income annuity (DIA) lets you pay a premium today in exchange for guaranteed income payments that begin at a future date you choose – for example, at age 75 or 80. The longer the deferral, the higher the income payments when they begin. OneAmerica’s Secure Income Stream is designed for buyers who want to pre-fund a future income floor years before they need it. It is distinct from a SPIA (which pays immediately) and a MYGA (which accumulates value with no mandatory income start). See our comparison of deferred income annuities for more detail.
