Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. Credit union services are available only to its shareholders. 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. Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. Credit union as a consumer cooperative operates on the principles of equality of all its members. Corporate alliances are intermediaries between credit unions and financial markets.
