Most modern credit unions represent specialized consumer cooperatives of citizens associated by the principle of social community: place of work, place of residence, profession, or any other shared interest. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. All the members of the credit union, regardless of gender, ethnicity, religious and political beliefs, as well as the size of the monetary share have equal rights. 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. In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Credit unions are competitors of savings institutions, adding interest on deposits of members. This applies to the shares, as well as to additional funds transferred to the account in the credit union. Credit unions base their activities on savings of shareholders, their shares and savings contributions, which make up the fund of mutual financial assistance - a source of cash loans to shareholders. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Unlike banks credit unions limit their activities to a closed circle of people.
