Membership in the credit union is voluntary and is open to all citizens bound by with joint work or residence, who wished to create a credit union to use its services and are willing to take on relevant commitments and responsibilities. In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). Like any financial institution, credit unions have the financial resources. 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. First central bank of credit unions appeared in 1876. Credit unions began to appear rapidly in many European countries. Cooperation between credit unions, how they would not have been named, took place always, from the moment when the movement moved outside one credit union. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Standards by which credit unions build their work do not coincide with the standards and regulations of consumer cooperation of the usual type.
