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. Like any financial institution, credit unions have the financial resources. 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 is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Among the U.S. credit unions, there are three groups that differ in terms of assets, shareholders, and business services. 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. 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. Corporate alliances are intermediaries between credit unions and financial markets.
