Major Rating Factors: Fair long-term capitalization index (4.5 on a scale of 0 to 10) based on fair current risk adjusted capital (severe loss scenarios), although results have slipped from the excellent range during the last year. Fair profitability index (4.7) with operating losses during 2025. Good liquidity (6.8) with sufficient resources (cash flows and marketable investments) to handle a spike in claims.
Other Rating Factors: Good overall results on stability tests (5.0) despite fair risk adjusted capital in prior years. Stability strengths include good operational trends and good risk diversification. Ample reserve history (9.5) that helps to protect the company against sharp claims increases.
Stability Factors: C - Past results on our Risk-Adjusted Capital tests. R - Concerns about the financial strength of its reinsurers.
