The difference between credit unions and banks is clearly is apparent when comparing the structure of assets and liabilities of credit unions and banks. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. The main activities of credit unions, aimed at the organization of mutual aid and social support of citizens is not intended to profit. 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. 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.
