Overtime Consider is 

2 - Product cost for operating section

The key difference between product costs and period costs is that products costs are only incurred if products are acquired or produced, and period costs are associated with the passage of time. Thus, a business that has no production or inventory purchasing activities will incur no product costs, but will still incur period costs.
