Luxembourg is the largest hub for reinsurance business, particularly captive reinsurance, in the European Union (EU). The availability of multilingual and multicultural experts, flexible and deferrable tax regimes, and an outward-looking policy approach have made the country the leading center for insurance and reinsurance business in Europe. The Commissariat aux Assurances (CA) regulates the country's reinsurance business which, by the end of 2012, comprised 238 companies. A number of reinsurers in Luxembourg originate from France, Germany, Italy, Belgium and Spain. In terms of market size, the Luxembourg reinsurance segment increased at a CAGR of 11.1% during the review period (2008-2012).
