AM Best has revised the outlooks to positive from stable and affirmed the Financial Strength Rating (FSR) of A+ (Superior) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of "aa" (Superior) of the members of RLI Group (RLI). In addition, AM Best has revised the outlook to positive from stable and affirmed the Long-Term ICR of "a" (Excellent) of RLI's publicly traded parent holding company, RLI Corp. (NYSE:RLI). All companies are headquartered in Peoria, IL. (See below for a detailed listing of the companies and ratings.)

The Credit Ratings (ratings) reflect RLI's balance sheet strength, which AM Best assesses as strongest, as well as its strong operating performance, favorable business profile and very strong enterprise risk management.

The positive outlooks reflect the consistently favorable balance sheet strength fundamentals, supported by the group's prudent capital management strategy, favorable reserve development trends, strong liquidity and sound asset liability management practices. The group's risk-adjusted capitalization, as measured by Best's Capital Adequacy Ratio (BCAR), remained at the strongest level as of year-end 2024, and is expected to be maintained at this level over the medium term. Strong and consistent internal capital generation has enabled RLI to grow its capital size considerably over the last five years (despite the return of significant capital in the form of stockholder dividends to RLI Corp.), with policyholder surplus reaching $1.8 billion as of year-end 2024, from $1.0 billion as of year-end 2019.

RLI's ratings also reflect strong operating performance across extended time periods and multiple underwriting cycles. The consistency in the group's underwriting results is driven by sound pricing discipline, diversification, as well as risk optimization and continues to be augmented by solid investment returns. RLI's sound risk management capabilities and focus on niche opportunities by concentrating on specialty markets that often are underserved has helped insulate it from the various stages of the traditional property/casualty market cycle. Further supporting the ratings are the strong financial flexibility afforded by RLI Corp., as evidenced by its modest financial leverage and strong fixed-charge coverage.

The FSR of A+ (Superior) and the Long-Term ICRs of "aa" (Superior) have been affirmed with the outlooks revised to positive from stable for the members of RLI Group:
