Earnings Per Share

12 Months Ended

Dec. 31, 2022

White Mountains calculates earnings per share using the two-class method, which allocates earnings between common shares and unvested restricted common shares. Both classes of shares participate equally in dividends and earnings on a per share basis. Basic earnings per share amounts are based on the weighted average number of common shares outstanding adjusted for unvested restricted common shares.

The following table presents the Company’s computation of earnings per share from continuing operations for the years ended December 31, 2022, 2021 and 2020. See Note 21 — “Held for Sale and Discontinued Operations”.
