The economic basis of credit unions - finances of a household. The main objective of the credit union - to ensure financial stability of a household, to ensure the priority of their shareholders' financial interests. 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. Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. National Credit Union Insurance Fund was created by Congress in 1970 to insure deposits of credit union members in the amount of 100 thousand dollars. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). The specifics of credit unions and, in some sense, their uniqueness lies in the fact that they work not for profit and do not appropriate profit. Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks. 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.
