In the U.S., credit unions have a clear organizational structure. All credit unions belong to one or the other parent credit union (there are 35 of them in the U.S.). Today in the UK there are about 700 credit unions with assets exceeding 200 million pounds. The uniqueness of credit unions is that they put together the principles and benefits of financial cooperatives, consumer cooperatives and mutual aid funds, born once by trade unions. 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
