Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. 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. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.).
