Inflation Accounting: Adjustments, Methods & Real-World Impact

TAKEAWAYS:

• Inflation erodes the purchasing power of money over time, making historical cost accounting misleading for long-term decisions.
• Current Cost Accounting (CCA) adjusts assets/liabilities to today’s prices, while Monetary/Non-Monetary Method separates items affected by inflation (e.g., cash, loans) from those that aren’t (e.g., inventory, equipment).
• Nepal’s NPSAS 16 mandates inflation adjustments for public sector entities, but private firms often use general price index adjustments for consistency.
• Worked examples show how a Kathmandu shop’s profit appears higher in nominal terms but lower when adjusted for inflation (e.g., Rs. 50,000 "profit" may buy only Rs. 30,000 worth of goods today).
• Real-world tie-ins: eSewa uses inflation-adjusted valuations for long-term loan repayments; NTC accounts for rising fuel costs in its depreciation schedules; Daraz’s inventory valuation reflects current market prices to avoid overstocking losses.
• Exam focus: Trace adjustments through T-accounts, restated financial statements, and ratio analysis (e.g., how inflation hides true profitability in PU/TU case studies).

Why Inflation Distorts Financial Statements

Inflation is the sustained increase in the general price level over time. When prices rise, the purchasing power of money decreases. For example:

• In 2010, Rs. 100 could buy 1 kg of rice. By 2023, the same Rs. 100 buys only 0.6 kg due to inflation.
• Problem: Traditional accounting (historical cost) records assets/liabilities at their original purchase price, ignoring inflation. This leads to:
  • Overstated profits (because costs appear lower than they are).
  • Misleading balance sheets (assets like inventory or machinery are undervalued).
  • Poor investment decisions (e.g., a business may seem profitable on paper but cannot afford to replace equipment).

Methods to Adjust for Inflation

Three primary methods are recognized under NPSAS 16 and IAS 29 (for hyperinflationary economies). Nepal’s economy (average inflation ~6-8% annually) does not qualify as hyperinflationary, but adjustments are still critical for long-term accuracy.

1. Current Cost Accounting (CCA)

Definition: Restates assets and liabilities to their current replacement cost (what it would cost to buy/replace them today). How it works:

• Non-monetary assets (inventory, PPE, intangibles) are adjusted to current prices.
• Monetary items (cash, loans, accounts receivable) remain unchanged (since they are fixed in nominal terms).
• Profit is recalculated using current costs.

Example for a Kathmandu Retail Shop (2023):

T-Account Adjustment:

Dr. Inventory A/c       Cr. Revaluation Reserve A/c
(650,000 - 500,000)     (150,000)

Impact on Profit:

• Nominal profit (historical cost): Rs. 200,000
• Adjusted profit (current cost): Rs. 120,000 (after deducting higher COGS).

    D --> E["Post to Revaluation Reserve"]
    E --> F["Restate Profit & Loss (using current costs)"]
    F --> G["Prepare Adjusted Financial Statements"]

2. Monetary/Non-Monetary Method

Definition: Separates items into those affected by inflation (monetary) and those that aren’t (non-monetary).

• Monetary items: Cash, loans, accounts receivable/payable (fixed in nominal terms).
• Non-monetary items: Inventory, PPE, intangibles (values change with inflation).

Adjustment Formula: For non-monetary assets: Adjusted Value = Historical Cost × (Current Price Index / Historical Price Index)

Example for a Daraz Warehouse (2023):

• 2022 Price Index (PI): 120
• 2023 PI: 140
• Historical Cost of Inventory: Rs. 800,000
• Adjusted Cost: 800,000 × (140/120) = Rs. 933,333

T-Account for Adjustment:

Dr. Inventory A/c       Cr. General Reserve A/c
(933,333 - 800,000)     (133,333)

Key Point: Monetary items are not adjusted because their value is fixed in nominal terms (e.g., a Rs. 100 loan remains Rs. 100, even if inflation reduces its real value).

3. General Price Index (GPI) Method

Definition: Uses a general price index (e.g., Consumer Price Index) to adjust all items uniformly. Formula: Adjusted Value = Historical Cost × (Current GPI / Historical GPI)

Example for NTC’s Depreciation Schedule (2023):

• 2022 GPI: 115
• 2023 GPI: 130
• Historical Cost of Vehicle: Rs. 5,000,000
• Adjusted Cost: 5,000,000 × (130/115) ≈ Rs. 5,652,174

Impact on Depreciation:

• Nominal Depreciation (2023): Rs. 500,000 (10% of historical cost)
• Adjusted Depreciation: Rs. 565,217 (10% of current cost)

How Inflation Adjustments Affect Financial Statements

Let’s trace the impact on a Kathmandu-based electronics shop (2023) using the Monetary/Non-Monetary Method.

Step 1: Unadjusted (Historical Cost) Financials

Step 2: Adjusted for Inflation (2023)

Assume:

• 2022 Price Index (PI): 110
• 2023 PI: 130
• Furniture’s current replacement cost: Rs. 1,040,000 (adjusted via CCA).

Adjustments:

1. Inventory:

   • Historical: Rs. 1,200,000
   • Adjusted: 1,200,000 × (130/110) = Rs. 1,363,636
   • Increase: Rs. 163,636

2. Furniture:

   • Historical: Rs. 800,000
   • Adjusted: Rs. 1,040,000 (via CCA)
   • Increase: Rs. 240,000

Adjusted Balance Sheet:

Adjusted Profit & Loss:

• COGS (adjusted): 1,363,636 (instead of 1,500,000)
• Gross Profit: 3,000,000 - 1,363,636 = Rs. 1,636,364 (vs. Rs. 1,500,000)
• Net Profit: 1,636,364 - 800,000 = Rs. 836,364 (vs. Rs. 700,000)

Key Insight:

• The nominal profit (Rs. 700,000) overstates true profitability.
• The adjusted profit (Rs. 836,364) reflects higher COGS due to inflation, but the real purchasing power of the profit is lower because prices rose.

## In the Real World

Inflation adjustments are critical in Nepal’s volatile economy. Here’s how businesses and institutions apply these concepts:

1. eSewa (Digital Payments)

   • Idea Used: Monetary/Non-Monetary Adjustments
   • How: eSewa’s long-term loans (e.g., for home renovations) are recorded at nominal value, but the real value of repayments is adjusted for inflation when calculating net income. For example, a Rs. 1,000,000 loan repaid over 5 years loses ~25% of its purchasing power if inflation averages 5% annually.
   • Impact: Helps eSewa set realistic interest rates and reserve funds for bad debts.

2. NTC (Telecom Infrastructure)

   • Idea Used: General Price Index (GPI) Method
   • How: NTC’s depreciation schedules for towers and cables use GPI-adjusted values. For instance, a tower costing Rs. 20,000,000 in 2020 is depreciated based on its 2023 replacement cost (adjusted via GPI), not its original cost.
   • Impact: Ensures NTC’s financial statements reflect the true cost of maintaining infrastructure amid rising material prices.

3. Daraz (E-Commerce Inventory)

   • Idea Used: Current Cost Accounting (CCA)
   • How: Daraz adjusts its inventory valuations monthly to reflect current market prices. For example, a shipment of electronics bought at Rs. 50,000 per unit in 2022 may cost Rs. 70,000 in 2023 due to global chip shortages. Daraz uses CCA to avoid overstocking losses.
   • Impact: Prevents Daraz from reporting inflated profits when selling old inventory at lower costs.

4. Nepal Rastra Bank (NRB) and Commercial Banks

   • Idea Used: Inflation-Adjusted Loan Valuations
   • How: Banks like NMB or Global IME use GPI-adjusted loan books to assess a borrower’s true repayment capacity. For example, a farmer’s Rs. 5,000,000 loan may seem manageable on paper, but if inflation is 7%, the real burden is closer to Rs. 5,350,000 by the end of the year.
   • Impact: Reduces non-performing loans (NPLs) by setting realistic collateral values.

5. NEPSE (Stock Market)

   • Idea Used: Comparative Financial Statement Analysis
   • How: Investors analyze listed companies’ inflation-adjusted EPS (Earnings Per Share). For example, a company reporting Rs. 10 EPS in 2023 may have real EPS of Rs. 7 after adjusting for 30% inflation. This explains why NEPSE’s P/E ratios often appear distorted without inflation adjustments.

Worked Example Tie-In: Consider Pathao’s driver payouts:

• In 2022, a driver earned Rs. 40,000/month.
• In 2023, due to inflation, the same nominal Rs. 40,000 buys 20% less fuel.
• Adjustment: Pathao uses GPI-adjusted minimum wage benchmarks to ensure drivers’ real earnings keep pace with inflation, avoiding strikes or driver attrition.

Advantages and Disadvantages of Inflation Adjustments

Nepal-Specific Challenge:

• Lack of reliable price indices: Nepal’s Consumer Price Index (CPI) is published quarterly, making real-time adjustments difficult for private firms.
• Solution: Many businesses use proxy indices (e.g., fuel price trends for transport firms, global commodity prices for importers).

## Exam Tip

This unit is highly numerical and tests conceptual understanding + application. Here’s how to score full marks:

1. Always show your work:

   • For adjustments, write the formula (e.g., Adjusted Value = Historical Cost × (Current PI / Historical PI)).
   • Use T-accounts for revaluation entries (e.g., Dr. Asset, Cr. Reserve).
   • Trace the impact on both the balance sheet and P&L.

2. Compare methods:

   • Exams often ask: “Which method is best for [scenario]?”
   • Answer template:

     “For [public sector/NPSAS compliance], the Monetary/Non-Monetary Method is ideal because it separates inflation-affected items. For [private firms with volatile assets], Current Cost Accounting is better as it directly adjusts replacement costs. However, the GPI Method is simpler and sufficient for [long-term assets like NTC’s infrastructure].”

3. Real-world application:

   • Link adjustments to Nepali businesses (e.g., “Like Daraz, a Kathmandu retailer must adjust inventory to avoid overstocking losses due to rising import costs.”).
   • Use NPSAS 16 or IAS 29 as authority where needed.

4. Common pitfalls to avoid:

   • Forgetting monetary items are unadjusted (e.g., don’t adjust cash or loans).
   • Miscounting indices: Ensure you divide current PI by historical PI, not the other way around.
   • Ignoring the P&L impact: Adjustments change COGS, depreciation, and thus profit.

5. Past exam patterns:

   • PU/TU often ask: “Prepare adjusted financial statements for [given data].” Always:
     1. Calculate adjustments.
     2. Show T-accounts.
     3. Present both unadjusted and adjusted statements side-by-side.
   • Case study tip: If given a receipts and payments account (like KK Sports in past papers), convert it to a cash flow statement first, then adjust for inflation.

Example Exam Question Breakdown: Question: “The following is the Receipts and Payments account of KK Sports for the year ended 2023. Adjust for inflation using the GPI method (2022 PI: 110, 2023 PI: 130).” Your Answer Structure:

1. Step 1: Convert Receipts & Payments → Cash Flow Statement (to identify opening/closing cash).
2. Step 2: Identify non-monetary assets (e.g., sports equipment) and adjust using GPI.
3. Step 3: Prepare adjusted Trial Balance and restated Profit & Loss.
4. Step 4: Highlight key insights (e.g., “The nominal profit of Rs. X understates true earnings by Rs. Y due to inflation.”).
