AM Best Affirms Credit Ratings of ICM Assurance Ltd

AM Best has affirmed the Financial Strength Rating of A (Excellent) and the Long-Term Issuer Credit Rating of “a” (Excellent) of ICM Assurance Ltd (ICMA) (St. Michael, Barbados). ICMA is a single-parent captive insurer, wholly owned by CNOOC International Limited, which is in turn wholly owned by CNOOC Limited (CNOOC), the ultimate parent. The outlook of these Credit Ratings (ratings) is stable.

The ratings reflect ICMA’s balance sheet strength, which AM Best assesses as strongest, as well as its adequate operating performance, neutral business profile, and appropriate enterprise risk management (ERM), augmented by rating enhancement that it receives from its ultimate parent, CNOOC. The ratings also incorporate AM Best’s blended view of ICMA’s captive exposures diversified globally among countries with largely predictable or developing legal, business and regulatory environments.

AM Best expects ICMA’s strongest level of risk-adjusted capitalization, as measured by Best’s Capital Adequacy Ratio (BCAR), to remain at a similar level prospectively. The balance sheet strength assessment also considers ICMA’s low underwriting leverage and strong liquidity measures. ICMA’s surplus consists of capital and underwriting profits retained in the captive and loaned back to its parent. The loan is repayable on demand with counterparty risk curbed due to the affiliation and the aligned interests of the two companies. In addition, the captive’s gross loss potential is elevated as it remains exposed to high severity events, due to the nature of the insurance ICMA provides for CNOOC’s oil and gas exploration. However, this risk is partially offset by safety programs and loss control provided by CNOOC, while reinsurance protection is placed to limit the captive’s net exposure to shock loss events.

ICMA has reported solid operating results, aggregating significant net operating profits recorded over the past five years. The captive’s loss experience remains favorable due to infrequent material catastrophic events, management’s inherent knowledge of the business and the strong loss control programs adopted at the parent level. ICMA’s business profile assessment considers its role as a single-parent captive providing global liability and property coverages to its ultimate parent and affiliates.

ICMA’s ratings receive lift from the ultimate parent due to implicit and explicit support, as well as other inherent benefits the captive receives from CNOOC. ICMA is considered a core element of CNOOC’s overall risk management and risk mitigation program and serves a critical role in delivering coverage and access to reinsurance for specific risks of its parent, subsidiaries and affiliates.
