Like any financial institution, credit unions have the financial resources. The number of shareholders of a credit union is limited and formalized by a list. Limit of the number is defined by the assembly and such assembly establishes the charter. Members of credit unions place in credit unions usually free fund balances, ie those that remain after expenses devoted to education of children, the acquisition of new properties, additional pension benefits, etc. International cooperation has been particularly felt since the days when Alphonse Desjardins began the activity on development of credit union movement in North America. To increase the number of credit unions in 1979 was adopted the corresponding law that serves as the legal basis of their activity.
