AM Best Downgrades Credit Ratings of Curi Insurance Group’s Members; Places Credit Ratings Under Review With Negative Implications
- April 09, 2026 04:07 PM (EDT)
//BestWire// - AM Best has downgraded the Financial Strength Rating (FSR) to A- (Excellent) from A (Excellent) and the Long-Term Issuer Credit Ratings (Long-Term ICRs) to “a-” (Excellent) from “a” (Excellent) of the members of Curi Insurance Group (Curi) (Raleigh, NC). Concurrently, AM Best has placed the Credit Ratings (ratings) under review with negative implications.
The ratings reflect Curi’s balance sheet strength, which AM Best assesses as strong, as well as its adequate operating performance, neutral business profile and appropriate enterprise risk management.
The FSR of A- (Excellent) and the Long-Term ICRs of “a-” (Excellent) have been placed under review with negative implications for the following members of Curi Insurance Group:
- UMIA Insurance, Inc.
- MMIC Insurance, Inc.
- Medical Mutual Insurance Company of North Carolina
- Medical Security Insurance Company
- MMIC Risk Retention Group, Inc.
The rating downgrades are based on the group’s surplus position, which has been impacted materially by significant adverse loss reserve development, driving large underwriting losses and increasing loss reserve metrics. Consequently, the group’s risk-adjusted capitalization, as measured by Best’s Capital Adequacy Ratio (BCAR), has been on a downward trend and no longer supports the strongest balance sheet strength assessment. This deterioration has been accompanied by rising underwriting leverage, adverse loss reserve development and gradually declining liquidity metrics.
The ratings have been placed under review with negative implications due to deterioration in Curi’s overall balance sheet strength and operating performance driven by material adverse development and surplus decline, significantly deviating from projections. Additionally, results raise questions regarding internal controls, due diligence and governance, as well as price adequacy, underwriting and the potential for future reserve strengthening. The group is exploring numerous strategies currently to mitigate ongoing issues. The ratings will remain under review with negative implications until AM Best is able to gather further information regarding the group’s future capitalization and operational plans.
