Material Changes vs. Prior Period
- Revenue Growth: Total revenue increased 7.8% to $14.71 billion, driven by a 6% increase in gross premiums written ($15.11 billion) and higher investment income.
- Underwriting Performance: The consolidated combined ratio increased slightly to 90.7% (from 90.3%). The loss ratio rose to 62.4% due to higher catastrophe losses ($336 million in 2025 vs. $298 million in 2024) and adverse prior year reserve development in the Insurance segment ($44 million), partially offset by favorable development in the Reinsurance segment ($47 million).
- Investment Results: Net investment income grew 7% to $1.43 billion, supported by a larger fixed maturity portfolio. Net investment gains increased to $132 million, primarily due to unrealized gains on equity securities.
- Currency Impact: The company reported net foreign currency losses of $68 million in 2025, compared to gains of $52 million in 2024, due to the weakening of the U.S. dollar.
- Capital Actions: The company repurchased 4.07 million shares for $270 million and paid $700 million in aggregate dividends (including special dividends of $1.50 per share).
Guidance, Outlook, and Risks
Management Commentary:
- Rate Environment: Average renewal premium rates for insurance and facultative reinsurance increased 6.7% in 2025. Rates for workers' compensation and certain professional liability lines continue to decrease, while property lines have moderated.
- Social Inflation: Management highlights "social inflation" as a key driver of adverse development in auto and other liability lines, citing higher settlement demands and litigation funding.
- Catastrophes: 2025 catastrophe losses were driven by California wildfires and severe storms. The company notes that climate change may alter the frequency and severity of such events.
Key Risks and Contingencies:
- Reserve Uncertainty: Loss reserves ($22.2 billion gross) are subject to significant estimation uncertainty, particularly for long-tail lines and emerging claims (e.g., cyber, mass torts).
- Reinsurance Credit Risk: Amounts due from reinsurers totaled $3.54 billion. The company monitors reinsurer financial strength but faces risk if reinsurers fail to pay.
- Regulatory Changes: The company is subject to evolving regulations regarding cybersecurity, artificial intelligence, climate risk disclosure, and capital standards (e.g., Solvency II, ICS).
- Legal Proceedings: A subsidiary is pursuing a lawsuit against reinsurers to recover over $90 million related to event cancellation policies; management expects a positive resolution.
Investor Verification Checklist
- Reserve Adequacy: Verify the assumptions used for loss reserves, particularly regarding "social inflation" in auto and liability lines, and the impact of the $44 million adverse development in the Insurance segment.
- Catastrophe Exposure: Review the company's catastrophe modeling and reinsurance coverage limits, given the $336 million in net catastrophe losses for 2025.
- Investment Portfolio Quality: Assess the credit quality of the $25.0 billion fixed maturity portfolio and the impact of interest rate changes on fair value (effective duration of 3.0 years).
- Reinsurance Recoverables: Confirm the financial strength of top reinsurers (e.g., Lloyd's, Partner Re, Munich Re) to whom $3.54 billion is owed.
- Dividend Sustainability: Evaluate the $1.4 billion limit on dividends payable from the lead insurer (Berkley Insurance Company) without regulatory approval to ensure future capital return capacity.
