AM Best Affirms Credit Ratings of Jupiter Insurance Limited

AM Best affirmed Jupiter Insurance Limited's Financial Strength Rating of A & Long-Term Issuer Credit Rating of "a", both with a stable outlook.
The ratings reflect Jupiter's very strong balance sheet, strong operating performance, neutral business profile, & appropriate enterprise risk management.
Jupiter's balance sheet is supported by its BCAR at the strongest level, with expectations to maintain sufficient capital buffers against high-severity losses.
The captive insurer does not purchase outward reinsurance, aligning with bp's strategy to retain risks.
A neutral factor in the assessment is Jupiter's concentrated investment portfolio, which consists of 99% short-term intragroup deposits.
Jupiter achieved a 9.4% five-year weighted average return-on-equity (2021-2025) driven by a 28.6% weighted average combined ratio & solid investment income.
The company operates as bp's principal captive insurer, underwriting property damage & business interruption cover for bp assets globally.
Prospective operating performance may experience volatility due to large line sizes relative to premium income.
