Meaning
Monetary value assigned to the stocks of raw resin and finished plastic goods held by a company at a specific time. Accurate inventory valuation determines the reported profit and the asset value on a balance sheet. It accounts for the purchase price of polymers plus any direct costs incurred to bring them to the moulding site.
Costing Methodology
Selection of first-in first-out or weighted average cost alters the financial result during periods of resin price volatility. When polymer prices rise, a first-in first-out inventory valuation results in a higher asset value and lower cost of sales. Using a weighted average tends to smooth out the impact of sudden price spikes on the income statement.
Balance Impact
Raw material warehouses represent a substantial portion of a moulder’s working capital. Large stocks of virgin resin require a precise inventory valuation to satisfy audit requirements and secure bank financing. This becomes complex when regrind and masterbatch are mixed into the calculation.
Market Adjustment
Write-downs happen when the current market price of the resin falls below its original purchase cost. If a moulder holds large quantities of high-density polyethylene during a market downturn, the inventory valuation must be lowered to the net realizable value.
