Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. 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. 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. Until the mid-XX century, credit unions in the United States had little assets that did not exceed, as a rule, 100 thousand dollars Initially, the target groups of credit unions were farmers (Raiffeisen), and now they include both individuals (credit unions), and organizations. Credit unions, like today's credit unions, emerged in the 19th century in Germany as a result of crop failure and famine. U.S. credit unions have another significant difference from the credit cooperatives of farmers: the first have major proportion of short-term loans, the second - long and mostly in real estate. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity. 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. A potential new member of a credit union must submit a recommendation of shareholders in which the referee becomes a warrant of a future member of the credit union.
