Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. 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. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations.
