AM Best has affirmed the financial strength and issuer credit ratings of MedPro Group and its affiliated insurers, citing the medical professional liability insurer's strong capitalization, consistent underwriting profitability and support from its parent, Berkshire Hathaway.

The rating agency affirmed the Financial Strength Rating of A++ (Superior) and the Long-Term Issuer Credit Ratings of "aa+" (Superior) for The Medical Protective Company and its affiliates, including Princeton Insurance Company, PLICO, Inc., Wellfleet Insurance Company and Wellfleet New York Insurance Company. The ratings also apply to reinsured affiliates MedPro RRG Risk Retention Group and AttPro RRG Reciprocal Risk Retention Group. The outlook for all ratings remains stable.

AM Best said the ratings reflect MedPro's "strongest" balance sheet strength, strong operating performance, favorable business profile and appropriate enterprise risk management.

The rating agency said MedPro maintains risk-adjusted capitalization at the strongest level as measured by Best's Capital Adequacy Ratio and has demonstrated an ability to underwrite profitably through varying medical professional liability insurance market cycles. AM Best also cited the group's extensive distribution network, claims-handling philosophy and enterprise risk management practices.

According to the agency, MedPro has consistently outperformed its peers through strong returns on equity, favorable operating ratios and sustained underwriting profitability. The ratings also benefit from financial support provided by National Indemnity Company and ultimate parent Berkshire Hathaway Inc., including affiliated reinsurance and investment management expertise.

AM Best said the ratings also reflect challenges facing the medical professional liability sector, including intense price competition, the erosion of tort reforms in some states, rising loss costs, regulatory uncertainty and ongoing consolidation among insurers and healthcare providers.

The agency also noted MedPro's historically significant allocation to common stocks, which can expose the group to investment volatility during market downturns. However, it said the insurer has maintained the strongest level of risk-adjusted capitalization because of its low underwriting leverage, affiliated reinsurance support from National Indemnity and substantial capital position.

AM Best added that MedPro has reduced its equity exposure over the past two years by shifting more assets into cash and short-term investments, although the group continues to maintain a meaningful allocation to equities.
