Loss development occurs when actual losses incurred vary from the Company’s previously developed estimates, which are established through the Company’s loss and LAE reserve estimate processes. Net incurred losses and LAE experienced favorable development of $3.0 million for the three months ended March 31, 2025. The prior period development for the three months ended March 31, 2025 of $3.0 million was driven primarily by favorable net loss development relating to the 2024 and prior accident years, resulting in a net release of $2.9 million from attritional reserves and $0.1 million from catastrophe reserves. These changes are primarily a result of ongoing analysis of claims emergence patterns and loss trends. The prior period development for the three months ended March 31, 2024 experienced an insignificant amount of development for the three months ended March 31, 2024.
