Percentages above are of 2,573,726 shares outstanding, as reported by WHITE MOUNTAINS INSURANCE GROUP LTD. on its Form 10-Q dated March 31, 2025 (see the filing on EDGAR). This is the count contemporaneous with the 2024-2025 meeting, not today’s. Each holding is as of its own filing, which may be dated before or after the meeting.
Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered funds disclose how they voted every proxy and institutional managers disclose their votes on executive pay (say-on-pay, say-on-frequency and golden parachutes), and Form 8-K Item 5.07, in which the company reports its own meeting results. Shares outstanding are taken from WHITE MOUNTAINS INSURANCE GROUP LTD.’s 10-Q dated March 31, 2025. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.
At WHITE MOUNTAINS INSURANCE GROUP LTD.'s shareholder meeting held May 22, 2025, in the 2024-2025 proxy season, 341 asset managers reported how they voted on 6 ballot items in their SEC Form N-PX filings, covering 2,186 separate fund positions. On the most widely held item on that ballot — Approval of the advisory resolution on executive compensation — FOR was 98% of the votes cast (FOR divided by FOR plus AGAINST, the conventional basis for proxy support; abstentions, broker non-votes and unvoted shares are excluded because none of them took a side), which is more than half. Whether the item was approved is for the filing to say; that statement has not been read for this item.
