Washington Mutual (WaMu) is the United States's largest savings and loan. Despite its name, it is not a credit union, and ceased being a mutual company in 1983. It is publicly traded on the New York Stock Exchange. In March of 2006, Washington Mutual began moving into its new headquarters, WaMu Center, located in downtown Seattle. The company's previous headquarters, Washington Mutual Tower, still stands about a block away from the new building on Second Avenue.
Washington Mutual's principal activities are to provide financial services to consumers and small businesses such as retail banking, mortgage lending, consumer lending, business banking, business lending, insurance services, credit card services, commercial real estate mortgage and consumer investment services.
Washington Mutual is the sole surviving major Seattle-based bank after the flurry of mergers in the 1980s and 1990s ended the independence of Rainier Bank, Seafirst Bank, and People's Bank, among others. Washington Mutual operates more than 2,600 retail banking, mortgage lending, commercial banking, and financial services offices, as of June 30, 2006.
