SEC Form 13F Filing History

This page shows a list of all the recent 13F filings made by White Mountains Insurance Group Ltd . Form 13F is required to be filed within 45 days of the end of a calendar quarter. The Form 13F report requires disclosure of the manager that files the report, the name and class of the security, the CUSIP number, the number of shares as of the end of the calendar quarter for which the report is filed, and the total market value. The market value column should not be used as a substitute for Assets Under Management (AUM), as it does not include cash held in accounts.
