The net decrease in the provision for claims of prior years during the first three months of 2025 reflects (i) lower than anticipated losses in the crop business and lower than anticipated claim frequency and severity in the trucking business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency and severity in the financial institutions business (within the Specialty financial sub-segment). This favorable development was partially offset by higher than anticipated claim severity in the excess liability businesses (within the Specialty casualty sub-segment). The net decrease in the provision for claims of prior years during the first three months of 2024 reflects (i) lower than anticipated losses in the crop business and lower than expected claim severity in the property and inland marine business (within the Property and transportation sub-segment), (ii) lower than anticipated claim severity in the workers’ compensation businesses and lower than expected claim frequency and severity in the executive liability business (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the fidelity business and lower than expected claim frequency and severity in the financial institutions business (within the Specialty financial sub-segment). This favorable development was partially offset by (i) higher than anticipated claim severity in the excess liability businesses and higher than expected claim frequency and severity in the social services business (within the Specialty casualty sub-segment) and (ii) higher than anticipated claim severity in the innovative markets business (within the Specialty financial sub-segment).
