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. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Credit unions also differ from the traditional consumer cooperatives. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress. Credit union as a consumer cooperative operates on the principles of equality of all its members.
