From 2004 until 2007 the club was sponsored by the Winterthur Group, a Swiss insurance company with offices in Barcelona since 1910, which led to the team featuring the birthplace of Joan Gamper, the club's founder, on their shirts. In 2006 the Winterthur Group was taken over by AXA, leading to a change in the club name. In the 2008–09 season, the club's sponsorship changed to Spanish insurer Regal (a division of Liberty Seguros, the Spanish subsidiary of American insurer Liberty Mutual).
