AM Best Maintains Under Review With Developing Implications Status for Credit Ratings of NORCAL Group’s Members

·3-min read

AM Best has maintained the under review with developing implications status for the Financial Strength Rating (FSR) of A- (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of "a-" for the members of NORCAL Group (NORCAL). (See below for a detailed listing of the companies.)

Originally, NORCAL’s Credit Ratings (ratings) were placed under review with developing implications on Dec.10, 2019, and the under review status was revised to developing on Feb. 26, 2020, following an announcement that ProAssurance Corporation [NYSE:PRA] planned to acquire NORCAL, upon its demutualization, in the fourth quarter of 2020. The under review status also considered the potential for additional reserve charges that had resulted in rating downgrades on Dec. 10, 2019.

Following a lengthy regulatory review process due to delays related to the pandemic, the acquisition closed on May 5, 2021. As part of its demutualization, $191 million of NORCAL’s policyholders surplus, which was approximately $543 million as of year-end 2020, was converted to contribution certificates, which negatively impacts risk-adjusted capitalization, as measured by Best’s Credit Adequacy Ratio (BCAR).

The developing implications reflect the potential for NORCAL’s ratings to be lowered if the balance sheet strength assessment were to decline due to changes in capitalization. However, now that the transaction has consummated, there also is the potential for NORCAL’s ratings to be stabilized or enhanced once the level of explicit and/or implicit support from ProAssurance can be determined following further discussions with management.

The ratings will remain under review pending further discussions with NORCAL’s new parent so that AM Best can fully assess the financial and operational impacts of the acquisition.

The FSR of A- (Excellent) and the Long-Term ICRs of "a-" remain under review with developing implications for the following members of NORCAL Group:

  • NORCAL Insurance Company (formally known as NORCAL Mutual Insurance Company)

  • NORCAL Specialty Insurance Company

  • Medicus Insurance Company

  • FD Insurance Company

  • Preferred Physicians Medical Risk Retention Group, a Mutual Insurance Company
