White Mountains Insurance Group (NYSE:WTM) Combined Ratio % Explanation
Combined Ratio % measures the money flowing out of an insurance company in the form of dividends, expenses and losses. A ratio below 100 percent suggests that the company is making an underwriting profit, while a ratio above 100 percent means that it paid more in the claim than it received. However, a ratio above 100 percent does not necessarily mean the company is losing money because the investment income is not included in the calculation.
Compared to Claims Ratio % and Expense Ratio %, the combined ratio is most important because it provides a comprehensive measure of an insurer's profitability.
