Membership in the credit union is voluntary and is open to all citizens bound by with joint work or residence, who wished to create a credit union to use its services and are willing to take on relevant commitments and responsibilities. Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. 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 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. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions.
