Swiss Re writes reinsurance for both property/casualty and life and health insurers. It will also write property/casualty reinsurance for corporate and public sector clients that are self-insured and help them manage their risk. For insurers looking to unload old books of life insurance, the company's Admin Re group will buy up closed books and maintain the policies. It also stays busy working to make the most of the assets generated by its other businesses. While Swiss Re is active around the globe, its activities in the Americas account for some 45% of the company's premiums. Operating from offices in more than 30 countries, Swiss Re sells its products globally through both direct sales and distributors.
