Underwriting Comes First. An insurance enterprise must respect the fundamentals of insurance. There must be a realistic expectation of underwriting profit on all business written, and demonstrated fulfillment of that expectation over time, with focused attention to the loss ratio and to all the professional insurance disciplines of pricing, underwriting and claims management.

Maintain a Disciplined Balance Sheet. The first concern here is that insurance liabilities must always be fully recognized. Loss reserves and expense reserves must be solid before any other aspect of the business can be solid. Pricing, marketing and underwriting all depend on informed judgment of ultimate loss costs and that can be managed effectively only with a disciplined balance sheet.

Invest for Total Return. Historically, GAAP accounting has tended to hide unrealized gains and losses on the investment portfolio and over reward reported investment income (interest and dividends). Regardless of the accounting, White Mountains must invest for the best growth in value over time. In addition to investing our bond portfolios for total after-tax return, that will mean prudent investment in equities consistent with leverage and insurance risk considerations.

Think Like Owners. Thinking like owners has a value all its own. There are stakeholders in a business enterprise and doing good work requires more than this quarter’s profit. But thinking like an owner embraces all that without losing the touchstone of a capitalist enterprise.

OneBeacon, with its U.S. corporate headquarters in Plymouth, Minnesota, is a specialty property and casualty insurance writer that offers a wide range of insurance products in the United States primarily through independent agencies, regional and national brokers, wholesalers and managing general agencies. As a specialty underwriter, OneBeacon believes that it will generate superior returns as compared to an underwriter that takes a more “generalist” underwriting approach and that its knowledge regarding its specialized insurance products, targeted industries, classes of business, risk characteristics and limited number of specialized competitors provides it with a competitive edge when determining the terms and conditions on individual accounts.
