The rating affirmations for Berkley Insurance and Berkley Regional reflect their historically favorable underwriting and operating performance, well-established market profile and solid risk-adjusted capitalization. The excellent operating cash flow and the considerable business diversification of both groups, in addition to their below average catastrophe exposure, were notable rating considerations as well.The rating affirmations of Admiral and Nautilus recognize the extremely profitable underwriting and operating performance, strong capitalization, excellent operating cash flow and demonstrated expertise in the surplus lines market of each group. A.M. Best believes the favorable performances of all four insurance groups are largely owed to their successfully executed, well-developed business strategies, which feature individual operating units focused on specific niche markets, primarily defined by types of customer, product orientation and distribution channel. Their demonstrated market expertise has led to excellent operating results over the long term that have fostered the long-term stability, which is a major reason for the above average retentions of each group. Partially offsetting these positive rating factors are the effects of weak macroeconomic conditions, competitive market pressures impacting both the surplus lines and specialty commercial markets, declining investment yields and above-average net underwriting leverage of the groups. These ratings also recognize the favorable prior year loss reserve development reported in recent years and the earnings garnered from these redundancies. The ratings of all the affiliated property/casualty groups consider the role and strategic importance of each within the W. R. Berkley organization. As such, A.M. Best views these groups as core business units of W. R. Berkley, which are afforded implicit and explicit support by the parent. The affirmation of the ratings for Berkley Life and Health acknowledges its continued favorable risk-adjusted capital position, which is expected to support the company’s growing business going forward, and the financial and operational support of W. R. Berkley. Berkley Life and Health is strategic in W. R. Berkley’s expansion in the accident and health market, primarily medical stop-loss coverage.
Potential upward movement in the ratings of the property/casualty groups or favorable change in the rating outlook could possibly occur if any of the groups exhibit notably enhanced operating results that lead to strengthened risk-adjusted capitalization. Possible negative pressure on the ratings or rating outlook could result from material deterioration in the risk-adjusted capitalization of any group, especially if it is caused by less favorable or unfavorable underwriting or operating results, or adverse prior year loss reserve development.For a complete listing of W.
