In the credit union compensation for use of the loan (interest) is a source of compensation for savings. Taking a decision to join a credit union, citizens create an organization through which they participate in the shared savings by mutual crediting and joint (collective) use of personal savings. 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.).
