FOR IMMEDIATE RELEASE
LONDON - JUNE 18, 2026 09:40 AM (EDT)
AM Best upgraded the Financial Strength Rating to A+ (Superior) from A (Excellent) and the Long-Term Issuer Credit Ratings to “aa-” (Superior) from “a+” (Excellent) of Solen Versicherungen AG (SVAG) (Switzerland) and Noble Assurance Company (Noble) (Texas, United States). The outlook of these Credit Ratings (ratings) is stable.
The ratings reflect SVAG’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. The ratings also factor in rating lift from SVAG’s parent company, Shell plc (Shell).
The upgrading of the ratings reflects the increased rating lift applied to SVAG’s ratings, reflecting the company’s strategic importance to the group, as a well-entrenched risk management tool. SVAG plays a key role in supporting Shell’s overall risk management framework, as the group’s principal captive. SVAG’s non-life business mostly consists of offshore and onshore property and liability risks, as well as the associated business interruption covers, which are core to the group’s operations. SVAG also writes life business that is derived from the reinsurance of the group’s pension liabilities.
SVAG’s balance sheet strength is underpinned by risk-adjusted capitalisation at the strongest level, as measured by Best’s Capital Adequacy Ratio (BCAR). AM Best expects the captive’s BCAR scores to remain above the minimum required for the strongest assessment level, reflecting the insurer’s strategy to maintain sufficient capital buffers to absorb a series of large losses. The balance sheet strength assessment also factors in a concentration of assets in intragroup investments, as well as the large gross and net line sizes offered by the captive relative to its capital base.
SVAG has a track record of strong operating performance, underpinned by robust underwriting results, as evidenced by a five-year (2021-2025) weighted average combined ratio of less than 25%. Prospective underwriting performance is subject to potential volatility due to the captive’s exposure to high-severity low-frequency losses, given its large net line sizes relative to its premium base. In addition, the captive is exposed to elevated market risk through its management of the Shell group’s foreign currency warehousing activities, which drives a level of variability in overall earnings. Nonetheless, SVAG’s key performance metrics are expected to remain supportive of a strong assessment over the medium term.
The ratings of Noble reflect its status as a member of the SVAG rating unit and a subsidiary of Shell. As a captive domiciled in Texas, Noble underwrites Shell’s U.S. business and cedes 100% of its risks to SVAG, its sister company, through a quota share reinsurance agreement.
