Learning Module 6 Analysis of Inventories

Measurement and standards5 min
Inventories are measured and reported differently under accounting standards and tax rules, and those measurement choices materially affect financial statements and ratios. Under IFRS inventories are carried at the lower of cost and net realizable value; net realizable value equals estimated selling price less costs to complete and sell. US GAAP historically used lower of cost or market for some methods but now aligns broadly with lower of cost and net realizable value for inventory methods other than LIFO and the retail method. A write-down to net realizable value reduces the inventory carrying amount and recognizes an expense; under IFRS subsequent reversals are required when recoveries occur (limited to original write-down), whereas US GAAP prohibits reversals. Producers of agricultural, mineral, and similar products may measure some inventories at net realizable value or fair value less costs to sell if industry practice and markets permit.

Key Points

  • IFRS: lower of cost and net realizable value
  • US GAAP: similar for most methods; LIFO and retail have market rules
  • IFRS permits reversals of write-downs; US GAAP prohibits reversals
  • Industry exceptions (agriculture, minerals) may use fair value less costs to sell
Inventory valuation methods and effects6 min
Choice of cost flow assumption (FIFO, LIFO, weighted average, specific identification) affects allocation of total cost of goods available for sale between cost of goods sold (COGS) and ending inventory. In periods of rising costs, FIFO allocates older lower costs to COGS and reports higher ending inventory and higher profit; LIFO allocates newer higher costs to COGS resulting in lower profit and generally lower inventory carrying values. In deflationary periods effects reverse. LIFO ending inventory often reflects older, lower costs and may be conservative; LIFO liquidations (selling more units than purchased in a period) can cause older low-cost layers to flow through COGS, artificially increasing profit. Analysts should adjust comparatives when companies use different methods—LIFO reserves can be used to convert reported LIFO balances to FIFO for comparability.

Key Points

  • FIFO vs LIFO: different profit and inventory impacts under inflation/deflation
  • Weighted average smooths cost effects
  • LIFO liquidation can distort profit
  • Use LIFO reserve to convert LIFO to FIFO for comparability
Write-downs, ratios, and disclosures6 min
Inventory write-downs reduce profit and inventory on the balance sheet, which can (a) worsen profitability and liquidity ratios and (b) artificially improve activity ratios (e.g., inventory turnover) because the asset base (denominator) falls. Under IFRS recoveries of prior write-downs are recognized in profit (up to the original write-down amount); under US GAAP reversals are not permitted. Common-size analysis of the cash flow statement and inventory ratios help in forecasting and comparing companies. Key ratios include inventory turnover (COGS ÷ average inventory), days of inventory on hand (365 ÷ inventory turnover), and gross profit margin (gross profit ÷ sales). Analysts should benchmark these ratios against industry peers and across time. Disclosure requirements under IFRS include the accounting policies for inventories, total carrying amount and classification (raw materials, WIP, finished goods), amounts recognized as expense (COGS), amount of write-downs and reversals, circumstances leading to reversals, and carrying amount pledged as security. US GAAP disclosures are similar but do not require disclosure of reversals since reversals are not permitted.

Key Points

  • Write-downs reduce profit and change ratios; activity ratios may appear stronger
  • IFRS requires reversal disclosures; US GAAP prohibits reversals
  • Essential ratios: inventory turnover, days on hand, gross margin
  • Footnotes should disclose policies, allowances, write-downs, and pledges
Analytical adjustments and forecasting5 min
Analysts should watch for changes in inventory composition (raw materials vs finished goods), valuation allowances for obsolescence, and significant changes in the allowance which affect cost of sales and margins. In valuation and forecasting, inventory valuation choice affects measures of free cash flow and return-on-assets; when prices change, the timing differences between accounting and replacement cost should be considered. Practical analytical adjustments include converting LIFO to FIFO via the LIFO reserve, restating comparatives for consistent cost formulas, estimating potential write-down risks (e.g., tech obsolescence), examining MD&A and footnotes for management commentary on inventory strategy and supply chain, and stress-testing ratios under alternative inventory valuations.

Key Points

  • Monitor inventory classification shifts and allowance changes
  • Convert LIFO to FIFO using LIFO reserve for comparability
  • Assess write-down risk and impact on covenants
  • Use common-size and ratio analysis to forecast cash flows and capital needs
