Credit union is created by a group of members who pursue a common interest. Agreeing to make regular contributions, they create a fund from which can borrow money for investments and replenishment of working capital at favorable interest rates. Is necessary that all shareholders of the credit union were members of a single community, would know each other well enough to enjoy mutual trust. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. 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.
