Certified Reinsurers

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Last Updated: December 10, 2024

Effective January 1, 2018, reinsurers may apply for certified status. This allows a domestic ceding company to reduce collateral requirements and still take full credit for reinsurance recoverables from a certified reinsurer under ch. Ins 52, Wis. Adm. Code, for those contracts entered into or renewed after the reinsurer has obtained certified status. This rule does not prohibit parties to a reinsurance agreement from agreeing to provisions establishing collateral requirements which exceed the minimum requirements.

This page documents the certification process, lists pending applications, and approved certified reinsurers.


Certification Procedure

The Applicant shall submit the Application Checklist for Certified Reinsurers (initial and renewal applications) and any other reasonable requirements deemed necessary for certification by the Commissioner. Upon notice and approval of the application, the effective date will be as of the beginning of the quarter in which the application notice has been posted for 30 days. The status will run through the end of the calendar year unless otherwise determined by the Commissioner. Please see s. Ins 5​2.02 (4m), Wis. Adm. Code , for the applicable law and regulation on certified reinsurers. Renewal applications are required to be submitted to be considered for certified status in the subsequent calendar year by October 1.

Questions concerning the initial or renewal application process for Certified Reinsurers may be directed to ocireinsurance@wisconsin.gov.
