Specialization of credit unions to provide financial services to its shareholders requires a particularly strict regulation of membership and acceptable activities. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Contributions from of shareholders in credit unions in no way can be considered as borrowed funds, they come from the shareholders and for the shareholders and can not be used to provide services to third parties. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. Credit union as a consumer cooperative operates on the principles of equality of all its members.
