Cost of goods sold - Inventory Valuation and Financial Impact

Importance of Inventories in Profit Measurement How Inventories Affect Reported Profit Inventories play a crucial role in determining a company's reported profit because they control when expenses are recognized. Here's why this matters: When a company sells inventory, it must record the cost of goods sold (COGS) as an expense in the period of the sale. This creates an important matching principle: the cost of inventory is matched against the revenue it generates in the same accounting period. Consider this example: A retailer purchases 100 units of clothing for $10 each in January for $1,000 total. The company doesn't immediately expense this $1,000. Instead, it records the $1,000 as an inventory asset on the balance sheet. When the retailer sells 60 units in February for $20 each, it records $1,200 in revenue and $600 in cost of goods sold ($10 × 60 units). The remaining 40 units stay on the balance sheet as inventory at $400. This way, the expense is recognized in the period when the revenue is earned. Without proper inventory tracking, companies could either overstate or understate profits by recognizing costs at the wrong times. Write-Downs and Allowances for Inventory Why Inventory Value Declines Inventory doesn't always retain its original cost. Several factors can reduce its value: Defective or damaged goods – Products with physical damage or manufacturing defects cannot be sold at full price Obsolescence – Items become outdated or out of fashion, reducing demand Substandard quality – Products that don't meet quality standards command lower prices Market price declines – General market conditions may cause prices to fall below what the company paid When any of these situations occur, the inventory value on the balance sheet needs to be adjusted downward to reflect economic reality. Lower of Cost or Market (LCM) Valuation Method The standard accounting treatment is to value inventory at the lower of cost or market (net realizable value). Here's what this means: Cost is what the company originally paid for the inventory. Market value (or net realizable value) is the amount the company could receive by selling the inventory today, less any costs to sell it. The rule is straightforward: compare the two amounts and use whichever is lower. Example: A company has winter coats that cost $50 per unit to purchase. It's now April, and the coats are not selling. The company determines it can only sell the coats for $30 each, minus $5 in remaining markdown and shipping costs, resulting in a net realizable value of $25 per unit. Cost: $50 per unit Net realizable value: $25 per unit Valuation under LCM: $25 per unit (the lower amount) The company must write down the inventory value from the original cost to the lower market value. How Write-Downs Affect Financial Statements When a company writes down inventory value, it creates a direct impact on both the income statement and balance sheet in the current period. On the income statement, the write-down is recorded as an expense (sometimes called an inventory write-down expense or loss on inventory). This reduces the company's net income in the current period. On the balance sheet, the ending inventory value is reduced to reflect the write-down. This lower inventory value also reduces total assets. Continuing the example: If the company has 1,000 winter coats: Original cost: $50,000 (1,000 units × $50) Write-down required: $25,000 (1,000 units × $25 decline) New inventory value on balance sheet: $25,000 The $25,000 write-down appears as an expense in the income statement for the current period, reducing reported profit by that amount. Write-Offs for Destroyed Inventory In rare circumstances, inventory may be destroyed by catastrophic events such as fire, flood, or theft. When this occurs, the entire loss is recognized immediately as an expense in the period of destruction. Key point: Unlike gradual write-downs for obsolescence or price declines, a write-off for destroyed inventory is treated as an extraordinary loss. The inventory is completely removed from the balance sheet, and the corresponding loss appears on the income statement. Example: A warehouse fire destroys $500,000 of inventory. The company immediately records a $500,000 loss on the income statement and removes the $500,000 from inventory on the balance sheet. Understanding Inventory's Role in Key Financial Metrics Cost of Revenue and Gross Margin To understand how inventory flows through the income statement, it's helpful to know two related concepts: Cost of revenue (or cost of goods sold for product companies) includes the cost of inventory sold plus any directly related costs such as distribution. This is the expense matched directly against sales revenue. Gross margin is calculated as: $$\text{Gross Margin} = \text{Sales Revenue} - \text{Cost of Goods Sold}$$ Gross margin represents the profit remaining after accounting for inventory costs but before operating expenses. Inventory write-downs reduce gross margin because they increase the cost of goods sold in the period the write-down occurs. Example: If a company has $1,000,000 in revenue and $400,000 in cost of goods sold (including a $50,000 inventory write-down), the gross margin is $600,000. Without the write-down, gross margin would have been $650,000. This illustrates why accurate inventory valuation directly affects key profitability metrics that investors and creditors use to evaluate company performance. <extrainfo> International Accounting Standards Inventory accounting is governed internationally by International Accounting Standard (IAS) 2), which sets requirements for how companies should measure and value inventory. Most countries follow these standards or have adopted them with minor modifications. The principles discussed in this section—including the lower of cost or market valuation and expense recognition timing—are consistent with IAS 2 requirements. </extrainfo>
