Legal forms
This is how the English wikipedia describes a Cooperative:
“A cooperative (also co-operative; often referred to as a co-op) is a business organization owned and operated by a group of individuals for their mutual benefit. Cooperatives are defined by the International Co-operative Alliance's Statement on the Co-operative Identity as autonomous associations of persons united voluntarily to meet their common economic, social, and cultural needs and aspirations through jointly-owned and democratically-controlled enterprises. A cooperative may also be defined as a business owned and controlled equally by the people who use its services or by the people who work there. Cooperative enterprises are the focus of study in the field of cooperative economics.”
This description matches the intentions of the Regional Economic Community very well.
