Historically, credit unions were preceded by widespread development of credit cooperation in many countries of Europe and America. Activity of the credit union consists of organizing mutual financial assistance by meeting the needs of its members in the services of saving and obtaining loans. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Until the 70's there was a proliferation of the U.S. credit unions due to the increase of their number and the number of shareholders, although it must be acknowledged that there was also and a qualitative growth. Since the early 80's started the process of consolidation of credit unions, leading to a decrease in their number with a simultaneous increase in the total number of members. Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. Credit unions encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). Credit Union - one of the most attractive financial institutions for the public being a non-profit alternative to banks.
