Ace Limited

Founded in 1985, ACE Limited was a Swiss-domiciled global holding company for a group of international insurance and reinsurance companies. It grew significantly through strategic acquisitions, offering a diverse range of products including property and casualty, accident and health, and life insurance to a varied client base. In a landmark transaction, ACE acquired The Chubb Corporation for $29.5 billion, and on January 14, 2016, the combined entity began operating under the renowned Chubb name. Today, Chubb is the world's largest publicly traded property and casualty insurance company.
