Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. Historically, credit unions have grown from the experience of credit cooperatives, but they took the experience of organizations of mutual aid of citizens by moving methods of social self-protection from labor and toward consumption. On the consumer credit market in the U.S. credit unions are on the third place after the commercial banks and finance companies and are ahead of savings institutions, not taking into account the loans on real estate.
