Answer:
Net realizable value less a normal profit margin.
Explanation:
Lower of cost or market rule of inventory states that cost of inventory recorded must be that at which cost is lower, and the original cost is the current market price.
This occurs when the inventory has become obsolete, market price has declined, or inventory has deteriorated
Net realisable value is defined as selling price minus estimated cost of completion.
So the market value should not be less than net realizable value less a normal profit margin.
