A Bermuda-based holding company that owns and invests in insurance, reinsurance, and related financial businesses, including Ark, a Lloyd's of London insurer, and Bamboo, a homeowners-insurance agency.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
