Arch Capital Group has completed its acquisition of Barbican Group Holdings, which includes Barbican Managing Agency Limited, Lloyd’s Syndicate 1955, Castel Underwriting Agencies Limited, and other associated entities.

Following close of the transaction, Barbican will be consolidated into Arch’s insurance and reinsurance operations, while continuing to develop partnerships with third-party capital relationships, a release said. Castel will continue to be operated independently, but will receive financial support from Arch.

Arch’s deal to purchase Barbican was first announced in late July.
