To get a loan in the credit union a shareholder must be not only a formally adopted there, but necessary pay in cash contributions, the amount and order of payment of which approved by the General Assembly and fixed by the charter. Credit unions attract people in the first place by the opportunity to get cash loan (credit) - quickly and relatively inexpensively. 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. 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. Credit unions perform the function of social protection in a vital for people sphere of financial services. They care about improving the financial literacy of the population, are working on the formation of their members and their employees. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. Credit unions appeared in England in the 19th century. In 1844 a group of workers from Rochdale established the first cooperative.
