Answer:
inventory impairment/cost of good sold (p/l) $500
Explanation:
IAS 2 requires that inventory be initially recognized at cost including cost of purchase and other necessary cost incurred in getting the inventory to the location where it becomes available for sale.
Subsequently, the item of inventory is carried at the lower of cost or net realizable value (NRV).
Quantity Unit Cost Unit NRV Lower of cost/NRV Amount
Model A 100 $100 $ 120 $100 $10,000
Model B 50 $50 $ 40 $40 $2,000
Model C 20 $200 $210 $200 $4,000
Adjustment required = 50 ($50 - $40)
=$500
