Mondragón, located in the Basque region of Spain, is a network of 264 companies, approximately half of which are worker cooperatives. Now the largest corporation in the Basque region and the seventh largest in Spain, MCC is also the world's largest worker co-op with over 34,000 members as of the end of 2007 and total employment of over 100,000. By 2010, co-op membership is expected to grow considerably to between 72,000 and 77,000, once Eroski, a network company that is mostly located outside of Basque County, completes the cooperative conversion process. Thirty-eight of MCC's industrial plants are located in fourteen countries around the world. Total sales in 2007 exceeded 16.7 billion Euros.
