Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. In the U.S. credit unions timely and full repayment of loans is a common phenomenon. Unpaid and delinquent loans are not more than 3% of their amount. 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. Unlike banks credit unions limit their activities to a closed circle of people. Corporate alliances are intermediaries between credit unions and financial markets.
