A.M. Best Withdraws Credit Ratings of Bison Insurance Company Limited

Business Wire

OLDWICK, N.J.--(BUSINESS WIRE)-- A.M. Best has affirmed the Financial Strength Rating of A (Excellent) and the Long-Term Issuer Credit Rating of “a” of Bison Insurance Company Limited (Bison) (Charleston, SC). The outlook of these Credit Ratings (ratings) remains stable. Concurrently, A.M. Best has withdrawn the ratings as the company has requested to no longer participate in A.M. Best’s interactive rating process.

The rating affirmations reflect Bison’s historically excellent risk-adjusted capitalization, consistent operating profitability driven by favorable underwriting results, conservative reserve levels and effective enterprise risk management controls. The ratings also recognize Bison’s history of maintaining sufficient capital and financial resources to support its ongoing obligations.

Partially offsetting these positive rating factors are Bison’s volatile underwriting results due to its low-frequency, high-severity risk profile, coupled with its high net retained limits relative to its available capital. Somewhat mitigating its risk profile is the company’s conservative reserving philosophy, except for pockets of adverse development and the ongoing demonstrated support from its parent, Duke Energy Corporation (Duke Energy) [NYSE: DUK].

Bison insures select risks for Duke Energy, providing a variety of coverage in property/casualty lines of business. While favorable operating performance has been reported consistently in the most recent five years and the first quarter of 2017, underwriting results are volatile, hence susceptible to occasional outsized losses, as evidenced in 2014 when it recorded an underwriting loss of $87 million, which eroded $49 million or 25% of the company’s capital and surplus. Nonetheless, this loss is somewhat mitigated by favorable geographic spread of risk and overall trend of favorable loss history. The outsized shock losses, which generally stem from high property losses, recur in five- to seven-year cycles. Duke Energy’s risk management team takes a holistic approach to managing its risks and utilizes the captive as an integral part of this process. Bison’s long-term growth opportunities primarily depend on Duke Energy’s business success.
