The exploitation rights licensed to the broadcaster have to revert to the producer after a maximum period of 7 years for a pre-sale or 10 years for a co-production.
Accordingly, there is some discretion in granting co-production status to an individual co-production if there is an imbalance between financial and creative contributions.
Co-production occurs in work systems in which customers are also participants, e.g., many work systems that provide medical care, education, and consulting.
