AM Best Affirms Credit Ratings of Chubb Limited and Its Subsidiaries
AM Best has affirmed the Financial Strength Rating (FSR) of A++ (Superior) and the Long-Term Issuer Credit Ratings (Long-Term ICR) of "aa+" (Superior) of the grouped subsidiaries of Chubb Limited (Chubb) (Zurich, Switzerland) (NYSE:CB). These include Chubb's rated U.S., Canada, Bermuda, Europe and Panama-based insurance and reinsurance subsidiaries (collectively Chubb Group of Insurance Companies, or Chubb Group). Concurrently, AM Best has affirmed the Long-Term ICRs of "a+" (Excellent) and the Long-Term Issue Credit Ratings (Long-Term IR) of Chubb Limited and Chubb INA Holdings LLC (Delaware). In addition, AM Best has affirmed the FSR of A+ (Superior) and the Long-Term ICRs of "aa-" (Superior) of Combined Insurance Company of America (Chicago, IL) and Combined Life Insurance Company of New York (Latham, NY) (together known as the Combined companies). AM Best also has affirmed the FSR of A- (Excellent) and the Long-Term ICR of "a-" (Excellent) of ACE Life Insurance Company (ACE Life) (Stamford, CT). At the same time, AM Best has affirmed the FSR of A (Excellent) and the Long-Term ICR of "a+" (Excellent) of Chubb Life Insurance New Zealand Limited (Chubb Life NZ) (New Zealand). The outlook of these Credit Ratings (ratings) is stable. (Please see the link below for a detailed listing of the companies and ratings.)
The ratings of the Chubb Group reflect Chubb's balance sheet strength, which AM Best assesses as strongest, as well as its very strong operating performance, favorable business profile and appropriate enterprise risk management (ERM). Chubb's very strong operating performance is anchored in the group's consistently highly profitable underwriting performance – as reflected in a combined ratio in the mid-to-high 80 percent range that notably outperforms industry averages for highly rated insurers – as well as consistently solid investment returns on a high-quality investment portfolio.
Chubb's business profile is notable for its product and geographic breadth and depth, as it operates in more than 50 countries and jurisdictions worldwide. Through ACE American Insurance Company and its pooled and/or substantially reinsured U.S. affiliates, Chubb is a market leader in U.S. commercial, specialty and agricultural insurance, as well as personal lines insurance for high-net-worth customers. Chubb's rated Bermuda operations – most notably Chubb Bermuda Insurance Ltd. (a leader in the excess casualty marketplace, with a leading position among national and multi-national corporations), and Chubb Tempest Reinsurance Ltd (an international multiline reinsurer that also serves as the intra-group reinsurance hub for many of Chubb's subsidiaries throughout the world) – are highly capitalized and are strategic assets for the group. Chubb European Group SE is one of the group's largest operating entities and the primary vehicle for providing a wide variety of coverages and lines of business across multiple markets to Chubb's European clients.
AM Best notes that Chubb's risk-adjusted capitalization, as measured by Best's Capital Adequacy Ratio (BCAR), has consistently stood at the strongest level, benefiting from a very high-quality investment portfolio and excellent historical reserve adequacy position, a solid reinsurance program, and a high quality of capital, in part reflecting relatively modest reliance on debt in the group's capital structure. Tempering capital strength is a somewhat elevated financial leverage relative to tangible capital, and a share repurchase program that has limited capital growth in recent years.
The ratings of the Combined companies reflect their balance sheet strength, which AM Best assesses as strong, as well as their strong operating performance, neutral business profile and appropriate ERM.
The ratings of ACE Life reflect its balance sheet strength, which AM Best assesses as very strong, as well as its marginal operating performance, very limited business profile and appropriate ERM. The ratings also reflect the continued financial support received from its parent.
The ratings of Chubb Life NZ reflect its balance sheet strength, which AM Best assesses as very strong, as well as its adequate operating performance, neutral business profile and appropriate ERM. The ratings also factor in rating enhancement from the company's parent and support from Chubb Limited.
A complete listing of Chubb Limited's FSRs, Long-Term ICRs and Long-Term IRs also is available.
