Answer:
Product costs are.
Step-by-step explanation:
Often the information needed by internal managers stands in sharp contrast to external reporting requirements promulgated by Generally Accepted Accounting Principles (GAAP).
GAAP requires full costing and management decision making requires incremental information.
According to GAAP, all manufacturing costs must be treated as product costs, and all selling and administrative costs must be treated as period costs.
Material cost + labor costs incurred directly in producing the product + other production or indirect production overhead costs.
If the products are in inventory, the costs are recorded as assets. If they have been sell, the are recorded as costs of goods sold.
