Ohio National (Acquired by Constellation Insurance / Rebranded as AuguStar)

Ohio National Financial Services was a Cincinnati-based mutual life insurance and annuities provider, historically operating through Ohio National Mutual Holdings, Inc. (ONMH). In March 2021 Constellation Insurance Holdings announced a sponsored demutualization of ONMH and Ohio National Financial Services for total consideration of approximately US$1 billion, including member consideration and new capital. The transaction closed on March 31, 2022, after a member vote on March 11, 2022, converting ONMH to a stock company renamed Ohio National Holdings, Inc. On July 17, 2023 Constellation repositioned and rebranded Ohio National's life insurance business as AuguStar Life, with the Ohio National Life Insurance Company and Ohio National Life Assurance Corporation expected to change their names to AuguStar Life Insurance Company and AuguStar Life Assurance Corporation in Q4 2023. Constellation Insurance is owned by long-term institutional investors CDPQ (Caisse de dépôt et placement du Québec) and Ontario Teachers' Pension Plan, and Constellation's family of insurance companies collectively held over US$34 billion in assets under management as of December 31, 2022. The product surface remains traditional life insurance, indexed life, and annuities distributed through agents and independent marketing organizations; no public developer APIs or OpenAPI specs are published.

Regulatory Posture applies to this provider. Its tags matched the Insurance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/ohio-national-mutual: open an issue to ask a question, or submit a pull request to add artifacts.
