Some credit unions are closed, serving only their members. However, the more and more popularitywin cooperatives of open type. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. 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. First Credit Union was savings unprofitable institution, or rather credit cooperative, providing services to its members. Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others.
