The net decrease in the provision for claims of prior years during the first three months of 2022 reflects (i) lower than anticipated losses in the crop business, lower than expected claim frequency in the trucking and ocean marine businesses and at the Singapore branch and lower than anticipated 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, lower than expected claim frequency in the executive liability business and lower than anticipated claim frequency and severity in the excess and surplus business (within the Specialty casualty sub-segment) and (iii) lower than anticipated claim frequency in the surety, trade credit and financial institutions businesses (within the Specialty financial sub-segment). This favorable development was partially offset by higher than anticipated claim severity in the targeted markets businesses (within the Specialty casualty sub-segment).

The net decrease in the provision for claims of prior years during the first three months of 2021 reflects (i) lower than anticipated claim frequency and severity in the transportation businesses, lower than expected losses in the crop business and lower than expected claim frequency in the aviation 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 and lower than anticipated claim frequency in the surety business (within the Specialty financial sub-segment). This favorable development was partially offset by (i) higher than expected claim frequency and severity in equine business (within the Property and transportation sub-segment) and (ii) higher than anticipated claim severity in the targeted markets, professional liability and excess liability businesses (within the Specialty casualty sub-segment).
