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. 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 encourage the proper use of shareholders savings, developing social programs (education, health, recreation, housing, etc.). 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.
