Principles of cooperative democracy and interaction were adequate to the purposes for which people joined credit unions. All the members of the credit union, regardless of gender, ethnicity, religious and political beliefs, as well as the size of the monetary share have equal rights. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. In the case of default the shareholder - individual will respond with its property and, in addition, is jointly and severally liable with the credit union's commitments. Shareholders in corporate organizations are basic credit unions, besides the same union can be a shareholder of several corporate organizations. Credit unions historically formed as a special form of social support, initially taken upon themselves the social mission of protecting the interests of citizens in the field of financial services.
