About this page

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 May 1, 2026. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At White Mountains Insurance Group, Ltd.'s shareholder meeting held May 21, 2026, in the 2025-2026 proxy season, 369 asset managers reported how they voted on 6 ballot items in their SEC Form N-PX filings, covering 2,150 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.
