Main share of credit unions assets is concentrated in loans (about 50%), while the share of consumer loans in commercial banks and finance companies active operations rarely exceeds 15%. The most common type of loans in credit unions are loans to purchase new and used cars (40%), followed by first mortgages and second mortgages (35%), about 10% are unsecured personal loans to member of unions and about 15% - are loans on credit cards and other loans. Some credit unions are closed, serving only their members. However, the more and more popularitywin cooperatives of open type. In the U.S. credit unions timely and full repayment of loans is a common phenomenon. Unpaid and delinquent loans are not more than 3% of their amount. 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. 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). Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations.
