Inventory valuation at lower of cost or NRV Steps:

• Identify cost components: production cost ($500) plus delivery cost to be incurred ($1000), assuming delivery brings inventory to saleable condition, totals $1500.
• Calculate NRV: expected selling price ($2500) minus estimated costs to complete and sell (if delivery is selling cost, NRV =$1500; if not, NRV = $2500).
• Compare: lower of cost ($1500 or$500) or NRV ($1500 or$2500) yields either $500 or$1500.
• Conclusion: Ambiguous delivery cost nature (inbound vs. outbound) prevents matching options.
