In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). Typically, donor contributions to the credit unions are targeted and used in the same statutory requirements and restrictions as the Mutual Financial Aid fund as a whole. Income received by the credit union shall be distributed among the shareholders or spent for the depreciation of services, that is, are the most effective means of meeting the needs of shareholders. 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. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks.
