Could the following be used in English: to perform a profitable activity; to realize a financing plan; to accept the undertakings of an association; legal entity/person
As it turns out, the one I was least sure of ("accept the undertakings of") returned the most hits on a Google search. Instead of perform a profitable activity, we would say make money, make a profit, turn a profit, or realize a profit.
It seems that realize a financing plan is used rarely if at all. Perhaps you mean something like finance a project?
