White Mountains Insurance Group Ltd's Comment on Sales, Marketing and Customers



The company serves insured customers who purchase insurance policies. Its markets include insurance companies (ceding companies) that enter into reinsurance agreements with reinsurance companies (reinsurers). Reinsurance reduces ceding companies' exposure to risks, protects against large losses, helps maintain capital levels, and increases underwriting capacity. Reinsurers may also acquire retrocessional reinsurance. Reinsurance is provided on either a treaty or facultative basis: treaty reinsurance covers specified portions or categories of risk, while facultative reinsurance is underwritten on a risk-by-risk basis. Expenses include claims or losses and loss adjustment expenses, such as insurance adjusters' fees and litigation costs. Losses and loss adjustment expenses are categorized by underwriting year or accident year for reporting purposes.
