LONDON — Omega Underwriting Holdings Plc announced yesterday that it has applied for shares in Bermuda-based Omega Insurance Holdings Ltd. to be listed on London’s Alternative Investment Market. Omega said it is anticipated that shares in the company will begin trading on AIM tomorrow, and that shares in Omega Underwriting Holdings will be cancelled at that time.

In September, London-based Omega, which operates at Lloyd’s of London and in the United States, said it would set up a new Bermuda-based holding company — Omega Insurance Holdings, to help it grow and develop its business.

Omega already has an operating subsidiary in Bermuda.

It is one of several Lloyd’s of London underwriters including Hiscox and Catlin that have or will be moving their domiciles to Bermuda for tax and regulatory reasons.
