OLDWICK, N.J.--(BUSINESS WIRE)-- AM Best has affirmed the Financial Strength Rating (FSR) of A++ (Superior) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of “aaa” (Exceptional) of National Indemnity Company (Omaha, NE) and its affiliates (collectively referred to as National Indemnity). These companies are subsidiaries of Berkshire Hathaway Inc. (Berkshire) [NYSE: BRK A and BRK B]. The outlook of these Credit Ratings (ratings) is stable.

The ratings of National Indemnity reflect its balance sheet strength, which AM Best assesses as strongest, as well as its very strong operating performance, very favorable business profile and appropriate enterprise risk management (ERM). The financial strength of ultimate parent Berkshire is also a material positive rating factor.

National Indemnity's balance sheet strength benefits from its solid risk-adjusted capitalization, which is typically maintained at the strongest level, as measured by Best’s Capital Adequacy Ratio (BCAR), but fell to the very strong level as of Sept. 30, 2022, following statutory surplus declines resulting from unrealized investment losses in the group’s sizable public equity portfolio. AM Best recognizes that National Indemnity is subject to occasional volatility in its BCAR due to fluctuations in investment values and believes that this volatility is mitigated by ample liquidity and vast financial resources, not only at National Indemnity’s level, but also at National Indemnity’s ultimate parent, Berkshire. Berkshire provides substantial financial flexibility, diversification and long-term competitive advantages associated with its non-insurance businesses, in addition to the benefit of Berkshire’s proven investment acumen.

National Indemnity’s steady underwriting performance has been augmented by substantial investment contributions during most periods, which has led to operating results that have outperformed AM Best’s reinsurance composite, as measured by a broad range of profitability metrics, over a prolonged time period.

The FSR of A++ (Superior) and the Long-Term ICRs of “aaa” (Exceptional) have been affirmed for National Indemnity Company and its following affiliates:

  • Columbia Insurance Company
  • National Fire & Marine Insurance Company
  • National Liability & Fire Insurance Company
  • National Indemnity Company of Mid-America
  • National Indemnity Company of the South
  • Berkshire Hathaway Specialty Insurance Company
  • Berkshire Hathaway Direct Insurance Company
