Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). Principles of cooperative democracy and interaction were adequate to the purposes for which people joined 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. When organizing the credit union it is important that people know each other and know the extent to which each of them is trustworthy. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. Unlike banks, in order to use the services of a credit union, you have to become its member, having written an application and having paid thus shares and membership fee. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate.
