Typically, donor contributions to the credit unions are targeted and used in the same statutory requirements and restrictions as the Mutual Financial Aid fund as a whole. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. Credit unions also differ from the traditional consumer cooperatives. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. 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. 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. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine.
