It's not a concern insofar as it's just a statement of fact. When there's a limit on the volume of product that can be either imported or exported, subject to some form of penalty or taxation or absolute volume, it creates an additional value in the ability to actually do the exportation or the importation. You may have excess inventory or you may have shortages of inventory. The fact that the bill contemplates that there will be transfers of quota or entitlement suggests that there will be payments for that.
