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. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Share contributions are transferred to the credit union on the basis of membership for the whole stay of a shareholder as member of the credit union and are the basis of membership. 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. The supreme body of the World Council of Credit Unions is the Assembly, which elects the president and the board of directors of WOCCU. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
