Determining Inventory Quantities
Ownership of goods
Physical inventory counting
Internal controls
Inventory Cost Determination Formulas
Specific identification, FIFO, Average cost
Effects of cost formulas
Inventory Errors
Presentation and Analysis of Inventory
Inventory Cost Formulas in Periodic System
Count physical inventory at end of each accounting period to:
Check accuracy of records
Determine shrinkage/theft
Goods in transit impact ownership determination:
Legal title determines inventory inclusion
Freight concepts: FOB shipping vs. destination
Consigned goods owned by consignor
Goods taken home "on approval" remain owned by the company
Strong internal controls necessary:
Review and reconciliation processes
Inventory counting as a control activity
Cost Formulas
Must apply unit costs after counting inventory
Various costs impact total inventory cost
Specific Identification
Tracks costs of individual items
Used only where items can be distinguished easily
FIFO (First-In, First-Out)
Assumes earliest goods purchased are sold first
Recent costs affect ending inventory
Average Cost
Computes a moving average of unit costs
Choose inventory formula that:
Closely represents physical flow
Reports ending inventory at recent cost
Consistent application across similar inventories
FIFO vs Average Cost on:
Cost of Goods Sold (COGS)
FIFO: Lower COGS in rising costs
Average Cost: Higher COGS under falling costs
Gross Profit & Net Income:
FIFO: Higher under rising costs
Average Cost: Higher under falling costs
Inventory Valuation:
Higher under FIFO in rising costs
Common errors:
Incorrect counting of ending inventory
Recording purchases in the wrong period
Effects on financial statements:
Impact COGS and net income
Overstated Inventory:
Understated COGS
Overstated Gross Profit and Income
Correcting errors in upcoming periods may lead to reverse effects on net income
Use LCNRV and accounting for inventory reductions.
Report inventory at lower of cost and NRV in notes to financial statements.
Inventory turnover ratio: Frequency of inventory sales
Days in inventory ratio: Average days inventory held
Optimal performance: Higher turnover, lower days in inventory
Both FIFO and Average can be applied in periodic systems with cost allocation at the end of the period.
