The insurance segment, the largest component, underwrites commercial and specialty lines through U.S. wholesale, programs and solutions, international, and global reinsurance divisions, earning premiums and investment income from a substantial equity and fixed-maturity portfolio. The industrial segment generates revenue from equipment leasing and construction products and services, while the financial segment provides investment management for insurance-linked securities and related program services. The company generates revenue and profit through disciplined underwriting practices in insurance, operational businesses in the industrial and consumer sectors, and investment gains on a diversified portfolio of equity and fixed-income securities.
