California Wildfires The California wildfires, commencing in January 2025, have led to a range of publicly available industry insured loss estimates. The Company expects its pre-tax net negative impact to be approximately 1.5% of the California wildfires’ aggregate industry insured loss. Based on a $50 billion aggregate industry insured loss, the Company estimates a pre-tax net negative impact on net income (loss) available (attributable) to common shareholders of approximately $750 million in the first quarter of 2025. The Company expects the wildfires will primarily impact its Property segment and, to a lesser extent, the Casualty and Specialty segment. Net negative impact on underwriting result includes the sum of (1) net claims and claim expenses incurred, (2) assumed and ceded reinstatement premiums earned and (3) earned and lost profit commissions. Net negative impact on net income (loss) available (attributable) to RenaissanceRe common shareholders is the sum of (1) net negative impact on underwriting result and (2) redeemable noncontrolling interest, both before consideration of any related income tax benefit (expense). The Company’s assessment of the impact from the California wildfires is preliminary, and is based on, among other things, initial industry insured loss estimates, market share analysis, the application of modeling techniques, a review of in-force contracts and potential uncertainties relating to reinsurance recoveries. It is difficult at this time to provide an accurate estimate of the financial impact of the California wildfires, including as a result of the preliminary nature of the information provided thus far by industry participants, the magnitude and recency of the California wildfires, and other factors. The Company’s actual net negative impact from this event will be reflected in the first quarter 2025 results of operations, when reported. Crash of American Airlines Flight 5342 On January 29, 2025, a helicopter collided with a commercial airline flight near Ronald Reagan Washington National Airport. The Company is in the preliminary stage of assessing the impact of this event on the Company’s financial results for the first quarter of 2025, and expects any impact would primarily be in the Casualty and Specialty segment. It is difficult at this time to provide an accurate estimate of the financial impact of this event given the preliminary nature of the information available, and other factors.
