What to Check

  • Inventory class, cost flow assumption, unit cost, production stage, WIP balance, lower-of-cost-or-market test, and write-down trigger.
  • Purchase record, production report, count sheet, costing system, COGS reconciliation, and note disclosure.
  • Effect on gross profit, working capital, cash conversion, taxes, obsolescence, and valuation multiples.
  • Whether the issue is raw materials, WIP, finished goods, consignment, spare parts, or inventory reserves.
  • Comparability across FIFO, LIFO, weighted average, standard cost, and reporting periods.

Common Mistakes

  • Treating inventory value as guaranteed sale value.
  • Ignoring obsolete, slow-moving, consigned, or written-down inventory.
  • Comparing gross margins without checking cost-flow assumptions.
  • Mixing production cost, period cost, and inventory reserve concepts.
