Depreciation, Fluctuation & Audit Decisions: Methods, Adjustments & Real-World Impact

TAKEAWAYS:

• Depreciation allocates an asset’s cost over its useful life; auditors verify method consistency (e.g., straight-line vs. diminishing balance) and useful life estimates against industry benchmarks.
• Inventory valuation methods (FIFO/LIFO/average) affect profit margins; auditors test for consistency, obsolescence, and net realizable value adjustments.
• Fluctuations in foreign exchange (FX) or commodity prices require auditors to assess hedging controls, translation adjustments, and impairment tests under IFRS/Nepali GAAP.
• Audit decisions hinge on materiality thresholds (e.g., 5% of profit) and substantive procedures like analytical reviews of depreciation trends or inventory turnover ratios.
• Real-world examples show how Daraz’s warehouse inventory uses FIFO to match cost of goods sold (COGS) with revenue, while Ncell’s depreciation policies for telecom towers differ from retail shops’ equipment.
• Exam focus: Worked numerical examples (e.g., calculating depreciation adjustments, FX translation impacts) and comparison tables (e.g., depreciation methods vs. inventory methods).

1. Depreciation: Methods, Audit Procedures, and Adjustments

Depreciation is the systematic allocation of an asset’s depreciable amount (cost minus residual value) over its useful life. Auditors must ensure:

• The method (straight-line, reducing balance, sum-of-years’ digits) is consistent with prior years and industry norms.
• The useful life and residual value are reasonable (e.g., a computer server may last 5 years vs. 10 years for a building).
• Impairment tests are performed if assets are underutilized or obsolete.

Depreciation Methods Compared

Depreciable Amount = 2,500,000 – 250,000 = NPR 2,250,000 Annual Depreciation = 2,250,000 / 5 = NPR 450,000 Book Value at End of 2022 = 2,500,000 – 450,000 = NPR 2,050,000

**Step 2: Calculate 2023 Depreciation (Incorrect: Reducing Balance)**

Year 1 Depreciation (2022) = 2,500,000 × 25% = NPR 625,000 (Incorrect; should be NPR 450,000) Book Value at Start of 2023 = 2,500,000 – 625,000 = NPR 1,875,000 Year 2 Depreciation (2023) = 1,875,000 × 25% = NPR 468,750

**Step 3: Audit Adjustment**
The auditor must **reverse the incorrect 2022 depreciation** and apply straight-line consistently:

Correct 2022 Depreciation: NPR 450,000 (Book Value: NPR 2,050,000) Correct 2023 Depreciation: (2,050,000 – 250,000) / 4 = NPR 475,000 Adjustment Entry (2023):

Why This Matters:

• Misstated profit: The shop’s 2022 profit was overstated by NPR 175,000 (625,000 – 450,000).
• Tax implications: Nepal’s Income Tax Act requires consistent depreciation methods; changes need board approval.
• Real-world tie: Daraz’s warehouses use accelerated depreciation for IT systems (reducing balance) but straight-line for buildings to align with tax laws.

2. Inventory Valuation: FIFO, LIFO, and Weighted Average

Inventory is valued at the lower of cost or net realizable value (NRV). Auditors test for:

• Consistency of method (FIFO/LIFO/average) across years.
• Obsolescence (e.g., unsold electronics in a Kathmandu shop).
• Cutoff errors (e.g., goods purchased in December recorded in November).

Inventory Methods Compared

• First, sell 500 units from opening inventory: 500 × 800 = NPR 400,000
• Next, sell 100 units from March purchase: 100 × 850 = NPR 85,000 Total COGS = 400,000 + 85,000 = NPR 485,000 Closing Inventory = 300 (March) + 400 (Sept) = 700 units, but only 600 counted → shortage of 100 units.

**Step 2: Audit Adjustment for Shortage**

Assuming the shortage is theft or damage, the auditor adjusts:

Real-World Tie:

• Daraz/Nepal’s Challenge: High inventory turnover requires real-time tracking to avoid FIFO/LIFO mismatches. Auditors use cycle counts (random sampling) to verify quantities.
• Ncell’s Inventory: Telecom equipment (e.g., base stations) is valued at NRV if obsolete, not cost.

3. Fluctuations: Foreign Exchange and Commodity Price Adjustments

Auditors must address:

1. Foreign Exchange (FX) Fluctuations:
   • Monetary items (e.g., loans in USD) are translated at year-end rates.
   • Non-monetary items (e.g., machinery purchased in USD) use historical rates.
   • Hedging controls: Check if the company uses forward contracts or natural hedges (e.g., importing goods in advance to lock prices).
2. Commodity Price Fluctuations:
   • Agricultural products (e.g., tea in Ilam) or minerals (e.g., NEPSE-listed lithium) require impairment tests if market value < carrying amount.

FX Translation Adjustment Example

Scenario: Nepal Pharmaceuticals borrowed USD 100,000 in 2022 (NPR 12,000,000 at exchange rate of NPR 120/USD). In 2023, the rate is NPR 130/USD. The loan is a monetary item.

Adjustment Entry (2023):

Exchange Gain/Loss = (100,000 × 130) – (100,000 × 120) = **NPR 1,000,000 gain**
| Particulars               | Dr (NPR)       | Cr (NPR)       |
|---------------------------|-----------------|-----------------|
| Foreign Exchange Gain     |                | 1,000,000       |
| Loan (Monetary Item)      | 1,000,000       |                |

Audit Procedures:

• Verify hedging documents (e.g., forward contracts with NMB Bank).
• Test consistency in translation methods (e.g., average rate vs. closing rate).

Real-World Tie:

• NEPSE Stocks: Companies like Nabil Bank or Global IME disclose FX translation adjustments in their annual reports. Auditors check for materiality (e.g., a NPR 50M gain may not be material if profit is NPR 500M, but a NPR 50M loss in a NPR 100M profit company is material).
• eSewa/Khalti: When processing international transactions (e.g., remittances from India), auditors verify FX rate consistency with RBI/Nepal Rastra Bank guidelines.

4. Audit Decisions: Materiality, Substantive Procedures, and Reporting

Auditors make decisions based on:

1. Materiality Thresholds:
   • Quantitative: Typically 5–10% of profit before tax (e.g., if profit is NPR 50M, a NPR 2.5M misstatement is material).
   • Qualitative: Even small amounts may be material if they affect compliance (e.g., underreporting VAT by NPR 100,000).
2. Substantive Procedures:
   • Analytical reviews: Compare depreciation expense to prior years (e.g., a sudden drop may indicate asset impairment).
   • Inventory confirmation: Send circularization letters to suppliers for goods in transit.
   • Depreciation recalculations: Recompute depreciation using management’s estimates vs. industry benchmarks.
3. Reporting:
   • Qualified opinion: If depreciation is understated (e.g., using a longer life than reasonable).
   • Adverse opinion: If inventory is overvalued (e.g., obsolete stock not written down).

Worked Example: Materiality Decision for a NEPSE-Listed Company Scenario: Nepal Oil Corporation reports a NPR 100M profit but the auditor finds:

• Understated depreciation on a refinery (NPR 5M).
• Overstated inventory due to obsolete crude oil (NPR 3M).

Step 1: Calculate Materiality Threshold

Materiality = 5% of NPR 100M = **NPR 5M**
- Understated depreciation (NPR 5M) = **Material** (directly affects profit).
- Overstated inventory (NPR 3M) = **Not material** (below 5%).

Step 2: Audit Response

• Adjust depreciation: Increase depreciation expense by NPR 5M → reduces profit by NPR 5M.
• No adjustment for inventory: But disclose in management letter as a key audit matter.

Real-World Tie:

• NTC’s Audit: Nepal Telecom’s annual report often highlights depreciation adjustments for telecom towers (useful life: 10–15 years). Auditors (e.g., PwC Nepal) check if NTC uses accelerated depreciation for rapid tech changes.

## In the Real World

1. Daraz Nepal’s Inventory Management:

   • Idea Used: FIFO inventory valuation and cycle counting for high-turnover items (e.g., electronics, groceries).
   • How: Daraz’s warehouses in Kathmandu and Pokhara use barcode scanning to track inventory layers. Auditors verify that old stock (FIFO layers) is sold first to avoid obsolescence. For example, if Daraz’s December 2023 inventory shows 10,000 units of a smartphone model but only 8,000 were sold, auditors check if the remaining 2,000 are obsolete (e.g., replaced by a new model) and require a write-down to NRV.

2. Ncell’s Depreciation Policies:

   • Idea Used: Reducing balance depreciation for telecom infrastructure (e.g., 4G towers) and straight-line for handsets.
   • How: Ncell’s 2023 annual report shows NPR 800M depreciation expense, with towers depreciated at 25% reducing balance (useful life: 10 years) and handsets at straight-line (useful life: 3 years). Auditors (e.g., Deloitte Nepal) test whether the 25% rate is justified by the rapid obsolescence of telecom tech. If Ncell suddenly switches to a 5% rate, auditors flag this as a red flag for management override.

3. NEPSE Share Valuation Fluctuations:

   • Idea Used: Fair value adjustments for financial instruments (e.g., investment in other companies) and FX translation for foreign subsidiaries.
   • How: Companies like Nabil Bank disclose NPR 200M gains/losses from USD-INR exchange rate changes in their notes. Auditors verify:
     • Whether hedging instruments (e.g., forward contracts) are used.
     • If impairment tests are performed for unlisted investments (e.g., a NPR 50M investment in a startup may need write-down if the startup’s valuation drops).

## Exam Tip

This unit is highly numerical and tests application over theory. Expect:

1. Worked Examples (50% of marks):

   • Depreciation: Given an asset’s cost, life, and residual, calculate adjustments for method changes or impairment.
   • Inventory: Given purchase/sales data, compute COGS and closing inventory under FIFO/LIFO and identify shortages or obsolescence.
   • FX Fluctuations: Calculate exchange gains/losses and hedging impacts.
   • Materiality: Given a profit figure and misstatements, decide whether to adjust and how to report.

2. Comparison Tables (20% of marks):

   • Depreciation methods vs. inventory methods (as shown above).
   • Final vs. Continuous Audit (though this is Unit 7, it’s often mixed here):

     Feature	Final Audit	Continuous Audit
     Timing	Conducted after the period ends	Ongoing throughout the period
     Evidence	Relies on year-end documents	Uses real-time data (e.g., ERP logs)
     Example in Nepal	Annual audit of NEPSE companies	Bank audits (e.g., NMB’s monthly reviews)

3. Short-Answer Questions (30% of marks):

   • Define depreciable amount, net realizable value (NRV), or hedging.
   • Differentiate between depreciation and fluctuation (see below).
   • State two audit procedures for verifying depreciation (e.g., recalculation, physical inspection of assets).

Common Pitfalls to Avoid

• Ignoring Residual Value: Always subtract residual value before calculating depreciation.
• Mixing FIFO/LIFO: If a company uses FIFO, never assume LIFO for audit adjustments.
• Materiality Misjudgment: A NPR 1M error in a NPR 10M profit company may not be material, but in a NPR 5M profit company, it is.
• FX Translation Errors: Monetary items (e.g., loans) use year-end rates; non-monetary items (e.g., machinery) use historical rates.

Past Exam Question Breakdown

For the question:

"As an auditor, what advice would you give on the following decision taken by the Board of Directors? i. A Company incurred NPR 200,000 preliminary expenses in the first year and because of the sufficient amount..."

Expected Answer Structure:

1. Identify the Issue: Preliminary expenses (e.g., setup costs) should be capitalized and amortized over their useful life, not expensed immediately.
2. Audit Procedure:
   • Recalculate the amortization (e.g., if useful life is 5 years, annual amortization = 200,000 / 5 = NPR 40,000).
   • Adjust the income statement by reducing profit by NPR 160,000 (200,000 – 40,000).
3. Reporting:
   • If the amount is material, issue a qualified opinion or adjusting entry.
   • If immaterial, note in the management letter for future compliance.

Final Note: This unit is scoring-friendly if you practice numerical examples and real-world ties. Always show your work in exams—partial credit is given for correct calculations even if the final answer is wrong. For FX questions, label your entries clearly (e.g., "Exchange Gain on USD Loan").
