Corporate credit unions are united on a cooperative basis in the Central Credit Union (US Central Credit Union). 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. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. Income derived from the provision of services to its members, does not become the profit of credit union and is distributed among its members in proportion to their savings. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. In some cases, the initiators of credit unions can be trade unions, associations such as social support centers and others. In the UK, credit unions are a source of financing of people groups. This tool is not widely used. A credit union on its own initiative order is created by citizens (individuals) to solve their financial problems that they could not solve in other financial institutions.
