Most modern credit unions represent specialized consumer cooperatives of citizens associated by the principle of social community: place of work, place of residence, profession, or any other shared interest. 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. 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 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. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. Consumer loan and reliable savings - these are the main goals, which mean "natural persons" having decided to unite in credit consumer cooperative. 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. 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.
