The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. 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. Credit unions of the open type are still controlled by their members, but at the same time provide services to people who are not its members (external customers). In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others.
