ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

 

On July 28, 2004, White Mountains Insurance Group, Ltd. issued a press release announcing its results for the three and six months ended June 30, 2004. The press release furnished herewith is attached as Exhibit 99.1 to this Form 8-K. Certain information included in the press release constitutes non-GAAP financial measures (as defined in Regulation G of the Securities and Exchange Commission). Specifically, non-GAAP financial measures disclosed in the press release are the discussion and presentation of fully converted tangible book value per common share.

 

White Mountains’ management believes that the growth in fully converted tangible book value per common share represents a measure of value created at the Company over time which is more relevant than traditional GAAP measurements.  Book value per share is derived by dividing the Company’s total GAAP shareholders’ equity as of a given date by the number of common shares outstanding as of that date, including the dilutive effects of outstanding options and warrants to acquire common shares, as well as the unamortized accretion of preferred stock. Fully converted tangible book value per share is derived by expanding the book value per share calculation to include (i) the effects of assumed conversion of all convertible securities and (ii) any remaining unamortized goodwill or deferred credits as of the applicable date. A separate schedule is included in Exhibit 99.1 to this Form 8-K which details the calculation of the Company’s fully converted tangible book value per common share.
