Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). In recent decades, many credit unions began to resort to such form of service as Credit union promotes the effective conservation of personal funds of its members, giving them the loans from the funds of the credit union, as well as the sharing of savings in education, housing, health care and other programs of social support and social development of its members. At the organization of the credit union it is important that people know each other and know the extent to which each of them is trustworthy. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative. The value of credit unions is not limited to the role of the economic agent - they are an important element of the social structure and a factor of social stability and progress.
