Depreciation and Valuation of Inventories Questions for SSC CGL

Depreciation: Concept and Methods

Depreciation is the systematic allocation of an asset's cost over its useful life. It reflects wear, obsolescence, and time passage. SSC CGL focuses on three main methods. Straight-line is simplest and most common in exams. Diminishing balance (or reducing balance) applies a fixed percentage to the book value each year, resulting in higher depreciation early on. Units of production ties depreciation to actual usage, not time. Choose the method based on asset type: machinery often uses diminishing balance; buildings use straight-line; vehicles may use units of production.

• Depreciation reduces asset value and increases expense on P&L
• Accumulated depreciation is a contra-asset account (reduces asset on balance sheet)
• Book value = Original cost minus accumulated depreciation
• Depreciation does not involve cash outflow in the year it is recorded
• Residual/salvage value is deducted in straight-line; not in diminishing balance

Inventory Valuation Methods

Inventory valuation determines the cost of goods sold (COGS) and closing stock value on the balance sheet. SSC CGL tests FIFO, LIFO, and weighted average under periodic inventory systems. FIFO (First-In-First-Out) assumes oldest stock is sold first; closing stock reflects latest prices. LIFO (Last-In-First-Out) assumes newest stock is sold first; closing stock reflects older prices. Weighted average spreads the total cost evenly across all units. In inflationary times, FIFO gives higher profit (lower COGS); LIFO gives lower profit (higher COGS). The choice impacts tax and financial statements significantly.

• FIFO: Oldest cost flows out first; closing stock at latest prices
• LIFO: Newest cost flows out first; closing stock at oldest prices
• Weighted Average: All units valued at average cost per unit
• Lower of Cost or Market (LCM): If market value < cost, value at market (conservative principle)
• Method choice affects COGS, profit, and closing stock valuation

Accounting Treatment and Journal Entries

Depreciation is recorded via journal entry: Debit Depreciation Expense, Credit Accumulated Depreciation. This reduces asset value on the balance sheet without affecting cash. Inventory is adjusted at year-end: the closing stock of one year becomes opening stock of the next. Adjusting entries for inventory typically involve the Purchases account and Stock account. When inventory value falls below cost (LCM), a write-down entry is made. SSC CGL often tests the correct account pairing and the impact on financial statements.

• Depreciation entry: Dr. Depreciation Expense / Cr. Accumulated Depreciation
• Accumulated Depreciation is a contra-asset; it reduces the asset's net book value
• Closing stock adjustment: Dr. Stock / Cr. Purchases (or via Trading Account)
• Inventory write-down (LCM): Dr. Loss on Inventory / Cr. Inventory
• Depreciation is a non-cash expense; it affects profit but not cash flow directly

Lower of Cost or Market (LCM) Principle

LCM is a conservative accounting principle: inventory is valued at the lower of its historical cost or current market value. If market price has dropped, the inventory is written down to market value, recognizing the loss immediately. This prevents overstatement of assets and profits. SSC CGL tests LCM application in closing stock valuation and the journal entry to record the write-down. The 'market' typically means replacement cost or net realizable value.

• LCM protects against overstating asset value and profit
• Applied item-by-item or to total inventory (SSC usually specifies)
• Write-down loss is recognized in the P&L statement
• Market value = replacement cost or net realizable value (selling price minus disposal costs)
• If market > cost, inventory remains at cost (no upward revaluation)

• Confusing accumulated depreciation with depreciation expense. Accumulated depreciation is the running total; depreciation expense is the current year's charge. Accumulated Depreciation is a balance sheet account; Depreciation Expense is an income statement account.
• Forgetting to deduct salvage value in straight-line method. Many students apply the rate to the full cost, inflating depreciation. Always: (Cost - Salvage) / Life.
• Mixing up FIFO and LIFO closing stock values. FIFO closing stock is at latest prices (higher in inflation); LIFO is at oldest prices (lower in inflation). Remember: FIFO = First In First Out means old stock leaves, new stock stays.
• Applying LCM upward. LCM is one-way: if market < cost, write down. If market > cost, keep at cost. Students sometimes incorrectly revalue upward.
• Treating depreciation as a cash outflow. Depreciation is a non-cash expense. It reduces profit but does not involve cash payment in that year.

• SLiM DBs: Straight-Line is simple and uniform; Diminishing Balance is steep early, shallow later. Think of a car: loses value fast when new, slower later.
• FIFO = Fresh In Fresh Out (newest stays); LIFO = Last In Last Out (newest goes). In inflation, FIFO profit is higher, LIFO profit is lower.
• LCM = Lower Ceiling Matters. Only go down, never up. Conservative = cautious = lower value.
• Accumulated Depreciation is a contra-asset (negative asset). It's like a debt against the asset's value, not a liability to outsiders.

• SSC CGL Tier-II typically has 1-2 direct depreciation questions (method selection, calculation) and 1-2 inventory valuation questions. Combined, they account for ~5-8% of the Accounts paper.
• Depreciation questions often ask: calculate depreciation for a year, find book value at year-end, or identify the correct method for a given asset. Straight-line is the default unless diminishing balance or units of production is explicitly mentioned.
• Inventory questions frequently present a scenario with multiple purchases at different prices and ask for closing stock value under FIFO, LIFO, or weighted average. LCM is often tested as a follow-up: 'If market price is Rs X, what is the closing stock value?'
• Watch for trick questions: 'Depreciation does not affect cash' (true, it's non-cash), 'Accumulated Depreciation is a liability' (false, it's a contra-asset), 'LIFO is always used in India' (false, FIFO is more common; LIFO is restricted for tax purposes).
• Time management: depreciation and inventory questions are calculation-heavy but straightforward. Allocate 2-3 minutes per question. Verify your method choice before calculating to avoid rework.
