National Credit Union Administration (NCUA) - an independent federal agency, based in Washington (State of Columbia), established by the U.S. Congress to oversee the federal credit union system. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of 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. 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 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. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Credit union as a consumer cooperative operates on the principles of equality of all its members.
