White Mountains adds Stephen Klar to 11-member board with no deal attached

Board expansion — Board increased from 10 to 11 directors

White Mountains elected Stephen Klar as a director and expanded its board to 11. The routine appointment carries no disclosed strategic or related-party angle.

This is a governance update, not an operating or capital signal. The filing gives no market benchmark or financial outlook to beat or miss; it simply announces that Stephen Klar was elected to the board. 〔0〕

The only structural change is a larger board. White Mountains increased its board size from 10 to 11 members, with Klar serving through the next annual meeting unless he leaves earlier. 〔1〕

There is no disclosed transaction or strategic arrangement behind the appointment. The filing says there were no election-related arrangements and no material related-party interest, making this a routine director addition rather than a visible change in control, strategy, or deal positioning. 〔2〕
