James J. Maguire, Jr. CEO said, “In the fourth quarter, we continued to see a wealth of new opportunities in our Commercial, Personal and Specialty lines business segments through our five distribution sources: Preferred Agents, Brokers, Wholesalers, Direct and the Internet. Pricing for most casualty lines has remained firm, but the pricing for the property lines has shown signs of weakening due to heightened competition. Renewal retention level percentages for quoted accounts remained in the mid 90’s. Additionally, our improved technology increased the speed of service for policy and endorsement issuance. I am confident in our ability to take advantage of the many opportunities that lie ahead for 2004.”
