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. Like the credit cooperatives, credit unions form associations of a higher level, which are called corporate credit unions. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. Members of credit unions place in credit unions usually free fund balances, ie those that remain after expenses devoted to education of children, the acquisition of new properties, additional pension benefits, etc. 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 some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others.
