A.M. Best Affirms Ratings of Castle Harbour Insurance Limited, Harrington Sound Insurance Limited and Colliers Bay Insurance Limited

OLDWICK, N.J.--(BUSINESS WIRE)-- A.M. Best has affirmed the financial strength rating of A (Excellent) and issuer credit ratings of “a” of Castle Harbour Insurance Limited, Harrington Sound Insurance Limited and Colliers Bay Insurance Limited (Cayman Islands) (together known as the captives). The outlook for all ratings is stable. All companies are domiciled in Bermuda, unless otherwise specified.

The ratings and outlook reflect the captives’ excellent capitalization and conservative operating strategy. The ratings also consider the captives’ critical role and favorable profile as part of the parent company, Schlumberger Limited, as well as their excellent operating performance during the past five years, providing tailored insurance coverage to subsidiaries of the parent for certain property/casualty risks.

Partially offsetting these positive rating factors are the captives’ relatively large limits in its general liability and property lines of business. Nevertheless, A.M. Best recognizes the substantial financial resources of the captives and its parent.

A.M. Best views the captives’ management and corporate strategy as a strengthening factor in its ratings, given the group’s conservative underwriting, operational goals and transparency. A.M. Best views the captives’ enterprise risk management practices as strong given the impact on its conservative risk culture, defined risk controls and the optimization of its capital and surplus. Other factors considered in A.M. Best’s ratings process include, but are not limited to, the diversification in line of business and geography, as well as the support and commitment of the parent and the group’s mission.

A.M. Best expects the captives’ future operating performance to be stable but strong, and the stable earnings profile should further support the companies to control growth and business writings, which are consistent with the captives’ capital and surplus position.

The outlook of the captives could be raised if operating performance improves and risk-adjusted capital remains supportive of the ratings. Negative rating pressure could occur if underwriting performance shows decline and demonstrates volatility that impacts negatively on earnings and capitalization over time. Negative rating pressure could also result if there is a material shift in risk profile that could potentially undermine the stability and profitability of the company. Financial issues resulting in ratings pressure and affecting the credit profile of the parent could impact the company’s ratings.

A.M. Best remains the leading rating agency of alternative risk transfer entities, with more than 200 such vehicles rated in the United States and throughout the world.
