​​​​​​​​​​​​​​​​​​​​​Last Updated: October 22, 2018

​​​​​​The Office of the Commissioner of Insurance (OCI) conducts about 50 financial examinations annually. These examinations are performed on insurance companies domiciled in the state of Wisconsin. State law requires that OCI perform a financial examination on an insurance company domiciled in the state at least once every five years.

A financial examination looks at the company's financial condition as of a particular date, usually December 31, to determine whether it meets the financial requirements to continue doing business in the state. In addition, the examiners review the insurance company's compliance with some of the many insurance laws under which it operates. (To see examination reports focusing on the business practices of insurers and producers see market conduct examinations.)

Links to the most recent copy of examination reports adopted are contained on this Web page. All prior examination reports are public record and a copy of the report may be requested through OCI's central files. There is a copy charge.

Any questions concerning any of the exam reports available on this Web page can be directed to OCI's Bureau of Financial Analysis and Examinations at ocifinancial@wisconsin.gov. (If Holding Company Chart not available in pdf format, please request paper copy from Bureau of Financial Analysis and Examinations, if needed.)
