AM Best Withdraws Credit Ratings of SUMIT Insurance Company Ltd.

OLDWICK, N.J.–(BUSINESS WIRE)–AM Best has downgraded the Financial Strength Rating (FSR) to A-
(Excellent) from A (Excellent) and the Long-Term Issuer Credit Rating
(Long-Term ICR) to “a-” from “a” of SUMIT Insurance Company Ltd. (SUMIT)
(Pembroke, Bermuda). The outlook of these Credit Ratings (rating) is
stable. Concurrently, AM Best has withdrawn the ratings at the request
of the company to no longer participate in AM Best’s interactive rating
process.

The ratings reflect SUMIT’s balance sheet strength, which AM Best
categorizes as very strong, as well as its marginal operating
performance, limited business profile and appropriate enterprise risk
management.

The downgrades reflect a material decline in surplus during the
company’s fiscal-year 2018 due to significant adverse development on
medical professional liability (MPL) claims as well as a dividend
payment. Reserves increased by 45% from the prior year while surplus
declined by 33%, which increased underwriting leverage metrics.
Commensurately, risk-adjusted capitalization, as measured by Best’s
Capital Adequacy Ratio (BCAR), declined significantly. SUMIT effectively
retains $10 million per claim, which is high relative to surplus, and
leaves the company exposed to increases in frequency and severity of
claims.

Operating performance has been very volatile, with underwriting losses
reported in four of the most recent five years, including a substantial
loss in 2018. Nevertheless, the company serves an important strategic
purpose as a captive insurance vehicle for Stanford Health Care and
benefits from the robust financial strength of its ultimate parent,
Stanford University.

AM 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. For current Best’s Credit Ratings and
