National Credit Union Administration (NCUA) - an independent federal agency, based in Washington (State of Columbia), established by the U.S. Congress to oversee the federal credit union system. Credit unions encourage savings of citizens, setting compensation payments (interest) on savings and provide from these savings loans to their members. Typically new members of the credit union become citizens having suretyship or recommendations from their friends - members of the credit union. The main advantage of credit unions consists in transparency, controllability, governance for shareholders. 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. The relationship of shareholders with credit union are not client-based, they are co-operative, based on different principles and standards, in particular, on the principles of the law of obligations. The relationship between credit unions and shareholders arise from the membership and are not customer relationship. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. Today, the World Council of Credit Unions is represented as members four regional confederations and twelve national associations.
