In 1908. the spread of credit unions has reached the United States. In 1935 President Roosevelt signed the state Charter on credit unions, which became a law. Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. Representative organization, leading the coordination work in the field of development of both global and national credit union movement is the World Council of Credit Unions (WOCCU) established in 1971 (headquartered in Madison, USA). Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. Credit unions also differ from the traditional consumer cooperatives. 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. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. All the members of the credit union, regardless of gender, ethnicity, religious and political beliefs, as well as the size of the monetary share have equal rights. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union.
