AM Best Affirms Credit Ratings of Jupiter Insurance Limited

LONDON--(BUSINESS WIRE)--AM Best has affirmed the Financial Strength Rating of A (Excellent) and Long-Term Issuer Credit Rating of “a” (Excellent) of Jupiter Insurance Limited (Jupiter) (Guernsey), a captive insurer of BP p.l.c. (bp) [NYSE: BP], an integrated global energy company. The outlook of these Credit Ratings (ratings) is stable.

The ratings reflect Jupiter’s balance sheet strength, which AM Best assesses as very strong, as well as its strong operating performance, neutral business profile and appropriate enterprise risk management. In addition, the ratings factor in a neutral impact from the company’s ultimate parent, bp.

Jupiter’s balance sheet strength is underpinned by its risk-adjusted capitalisation at the strongest level, as measured by Best’s Capital Adequacy Ratio (BCAR). AM Best expects Jupiter’s BCAR scores to remain comfortably at the strongest level prospectively, reflecting the company’s strategy to maintain sufficient capital buffers to absorb potential volatility stemming from the company’s exposure to high-severity, low-frequency losses. In line with bp’s current strategy to retain risks where possible, Jupiter does not purchase any outward reinsurance cover. A partially offsetting factor to the balance sheet strength assessment is the captive’s concentrated investment portfolio, of which 99% is accounted for by short-term intragroup deposits.

Jupiter has a track record of reporting positive operating results, demonstrated by a five-year (2021-2025) weighted average return-on-equity of 9.4%. Earnings are supported by robust underwriting profits, as evidenced by a weighted average combined ratio of 28.6%, and are supplemented by solid investment income. Prospective operating performance is subject to volatility, driven by the large line sizes offered by the captive, relative to its premium income.

Jupiter’s neutral business profile reflects its position within bp’s risk management framework as its principal captive insurer. The company’s underwriting risks consist mainly of onshore and offshore property damage and business interruption cover, on bp assets globally.

AM Best remains the leading rating agency of alternative risk transfer entities, with more than 200 such vehicles rated throughout the world. For current Best’s Credit Ratings and independent data on the captive and alternative risk transfer insurance market, please visit www.ambest.com/captive.
