In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). The first credit union in the United States was founded in 1909. by the group of Franco-American Catholics in Manchester, New Hampshire, and was called "Cooperative Credit Association of St. Mary. " Borrowing rate for the credit union is a source of income to cover the administrative costs. All excess funds are returned to members in the form of dividends on savings. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. In the case of default the shareholder - individual will respond with its property and, in addition, is jointly and severally liable with the credit union's commitments.
