AM Best Withdraws Credit Ratings of Michigan Professional Insurance Exchange

OLDWICK, N.J.--(BUSINESS WIRE)--AM Best has affirmed the Financial Strength Rating of A- (Excellent) and the Long-Term Issuer Credit Rating of “a-” (Excellent) of Michigan Professional Insurance Exchange (MPIE) (Grand Rapids, MI). The outlook of these Credit Ratings (ratings) is stable. Concurrently, AM Best has withdrawn these ratings as the company has requested to no longer participate in AM Best’s interactive rating process.

The ratings reflect MPIE’s balance sheet strength, which AM Best assesses as very strong, as well as its adequate operating performance, limited business profile and appropriate enterprise risk management. The ratings also reflect rating enhancement provided by Curi Insurance Group.

MPIE’s balance sheet strength assessment is supported by the strongest level of risk-adjusted capitalization, as measured by Best’s Capital Adequacy Ratio (BCAR), and is underpinned by a significant reduction in underwriting risk following MPIE being placed into run-off effective Jan. 1, 2024. This followed its 2023 acquisition and the related loss portfolio transfer and quota share reinsurance agreements by and among Constellation Solutions, Inc., and MMIC Insurance, Inc. (MMIC), which are subsidiaries of Curi Holdings, Inc. Under these agreements, 100% of MPIE's net loss, loss adjustment expenses, and unearned premium reserves were ceded to MMIC. All eligible policies were renewed by MMIC. MPIE’s balance sheet strength assessment also reflects the exchange’s limited scope and decline in surplus as all subscriber savings accounts and unassigned surplus as of the date of the acquisition have been paid to subscribers. The exchange does benefit from a liquid investment portfolio and has a history of prudent reserving and favorable development. Nevertheless, future earnings prospects are limited due to recent changes in business strategy.
