ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY
ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY is a registered legal entity registered in Ireland under IE457160, and its current status with Companies Registration Office (CRO) is active. The company was incorporated on 12 May 2008 and lists its registered address as BALLSBRIDGE DUBLIN 4., Ireland. 1 shareholder is on record for ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Group Structure
ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY sits 3 levels below its ultimate parent, Arch Capital Group Ltd., registered in Bermuda. 2 subsidiaries are recorded beneath it, across 2 jurisdictions. Immediately above ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY is ARCH FINANCIAL HOLDINGS EUROPE II LIMITED, holding 100% as filed in ARCH REINSURANCE EUROPE UNDERWRITING DESIGNATED ACTIVITY COMPANY's own shareholder record with Companies Registration Office (CRO). Arch Capital Group Ltd. sits further up the chain, a link derived by walking shareholder filings across jurisdictions rather than stated in a single document. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span Ireland, United Kingdom jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. One of the 2 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
