A.M. Best Affirms Credit Ratings of The Hartford Steam Boiler Group's Members


A.M. Best has affirmed the Financial Strength Rating (FSR) of A++ (Superior) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of "aa+" of the members of The Hartford Steam Boiler Group (HSB). The outlook of these Credit Ratings (ratings) remains stable. (See below for a detailed listing of the companies.)

The ratings reflect HSB's balance sheet strength, which A.M. Best categorizes as strongest, as well as its very strong operating performance, very favorable business profile and very strong enterprise risk management (ERM).

HSB's superior level of risk-adjusted capitalization, as measured by Best's Capital Adequacy Ratio (BCAR), coupled with strong financial and operating leverage, as well as historical trend in strength of reserves collectively contribute to an overall balance sheet assessment of strongest by A.M. Best. Additionally, consistently favorable earnings, including investment income, lead to an overall operating performance assessment of very strong.

A.M. Best views HSB's business profile as very favorable due to the company's unique market profile, geographical diversification and market penetration. HSB is a leading provider of equipment breakdown (boiler and machinery), specialty engineering insurance and equipment inspection services, and it continues to maintain this position with superior loss control capabilities, technical expertise and a unique equipment failures database.

The rating affirmations also reflect the group's synergies with Munich Reinsurance America, Inc. and its ultimate parent, Munich Reinsurance Company (Munich Re). HSB's relationship with Munich Re has provided access to new markets. Furthermore, HSB's robust ERM practices receive additional benefits from Munich Re's extensive ERM resources. HSB's historically strong underwriting results are a testament to the group's superb risk management capabilities. A.M. Best assessed the companys ERM as very strong.



HSB Group's product expansion and enhancement efforts, beyond its core business line, include homeowners and farmowners equipment breakdown coverage; employment practices liability; insurance for renewable energy facilities; and identity recovery, data compromise and cyber liability coverages.

A.M. Best believes that the members of HSB Group are well-positioned at the current rating level. However, positive rating actions could occur if there were upward rating movement at the ultimate parent level. Factors that may lead to negative rating actions include a sustained, material deterioration in operating performance or substantial deterioration in risk-adjusted capitalization.

  • The Hartford Steam Boiler Inspection and Insurance Company
  • The Hartford Steam Boiler Inspection and Insurance Company of Connecticut
