Accounting Concepts & Audit Adjustments: Adjusting Entries, Errors, Fraud, and Statements

TAKEAWAYS:

• Accounting concepts (e.g., accrual, consistency, materiality) are the foundation for auditors to assess whether financial statements are fair and compliant.
• Audit adjustments correct errors (e.g., omissions, misclassifications) and fraud (e.g., fictitious sales) to ensure accuracy in financial reporting.
• Rectifying entries reverse incorrect transactions (e.g., overstated purchases, understated depreciation) using T-accounts and journal entries.
• Materiality determines whether an adjustment affects stakeholders’ decisions—small errors may be ignored, but large ones require correction.
• Real-world ties: Banks (e.g., Global IME) adjust loan interest monthly; e-commerce (e.g., Daraz) verifies inventory counts to prevent overstatement.
• Exam focus: Past questions test rectifying entries, concept applications, and adjustment impacts on profitability (e.g., "How does overstated revenue affect net income?").

1. Core Accounting Concepts and Their Audit Implications

Auditors rely on GAAP (Generally Accepted Accounting Principles) and IFRS to evaluate whether financial statements are prepared correctly. Below are key concepts with audit relevance:

1.1 Accrual Concept

• Definition: Revenue and expenses are recorded when they are earned or incurred, not when cash is received or paid.
• Audit Check:
  • Verify unrecorded revenues (e.g., Nepal Telecom’s uncollected billings).
  • Check for prepaid expenses (e.g., Ncell’s advance payments for spectrum licenses).
• Example: If a Kathmandu restaurant (Thamel Bistro) records rent as an expense only when paid (cash basis), the auditor must adjust it to accrual basis by recognizing rent expense monthly, even if paid annually.

1.2 Matching Concept

• Definition: Expenses are matched with the revenues they help generate in the same period.
• Audit Check:
  • Ensure costs (e.g., Daraz’s advertising) are matched to sales periods, not arbitrarily shifted.
  • Review depreciation (e.g., Nepal Rastra Bank’s ATM machines) to confirm it aligns with asset usage.
• Visual: Matching in Action

    D["Audit Adjustment:\nIf rent was prepaid in 2022 but expensed in 2023, correct by:\nDr. Rent Expense (2022) Cr. Prepaid Rent"]

1.3 Consistency Concept

• Definition: Accounting methods must remain unchanged across periods unless a better standard is adopted.
• Audit Check:
  • Compare depreciation methods (e.g., Nepal Electricity Authority’s switch from straight-line to reducing balance).
  • Ensure inventory valuation (FIFO/LIFO) is applied uniformly.
• Example: If Khalti suddenly changes from FIFO to LIFO inventory valuation mid-year, the auditor must assess whether this distorts comparability.

1.4 Materiality

• Definition: An item is material if its omission/misstatement could influence economic decisions.
• Audit Threshold:
  • Typically 5–10% of net income or total assets (e.g., Rs. 50,000 in a shop with Rs. 5,00,000 profit).
  • Example: A Rs. 20,000 error in eSewa’s transaction fees is material; a Rs. 2,000 error is not.

1.5 Going Concern

• Definition: Assumes the business will continue operating for the foreseeable future.
• Audit Check:
  • Review cash flow, debt levels (e.g., Nepal Airlines’ liquidity crises).
  • If doubt exists, disclose in the audit report.

2. Types of Errors and Fraud: How Auditors Detect Them

Errors and fraud distort financial statements. Auditors classify them as:

3. Rectifying Entries: Step-by-Step with a Nepali Business Example

Scenario: Kathmandu Retail Shop (a TU exam favorite) has the following issues:

1. Overstated Purchases: The purchase book total is Rs. 2,00,000, but the actual total is Rs. 1,80,000 (Rs. 20,000 overcast).
2. Understated Depreciation: Depreciation on machinery (cost: Rs. 5,00,000, life: 10 years) was omitted for 2023.
3. Prepaid Insurance: Rs. 30,000 paid in 2023 for 2024’s insurance was recorded as an expense.

Step 1: Identify the Misstatements

• Purchases Overcast: Assets (Inventory) are overstated by Rs. 20,000.
• Depreciation Omitted: Net income is overstated by Rs. 50,000 (Rs. 5,00,000 / 10 years).
• Prepaid Insurance: Expenses are overstated by Rs. 15,000 (2023’s share of Rs. 30,000).

Step 2: Prepare Rectifying Journal Entries

Use T-accounts to visualize corrections:

gantt
    title Rectifying Entries for Kathmandu Retail Shop
    dateFormat  YYYY-MM
    section Adjustments
    Overcast Purchases: 2023-12, 2023-12, after
    Understated Depreciation: 2023-12, 2023-12, after
    Prepaid Insurance: 2023-12, 2023-12, after

Journal Entries:

Step 3: Impact on Financial Statements

• Balance Sheet:
  • Inventory decreases by Rs. 20,000.
  • Accumulated Depreciation increases by Rs. 50,000.
  • Prepaid Insurance increases by Rs. 15,000.
• Income Statement:
  • Net income decreases by Rs. 65,000 (Rs. 50,000 depreciation + Rs. 15,000 insurance adjustment).

4. Audit Adjustments vs. Audit Notes

5. Special Cases: Unrecorded Liabilities and Contingencies

Auditors must ensure all liabilities are recorded, especially:

• Unrecorded Expenses: E.g., Nepal Electricity Authority’s unpaid supplier bills.
• Contingent Liabilities: Potential obligations (e.g., Nepal Airlines’ pending lawsuits).

Adjustment Example: If Daraz owes Rs. 50,000 to a supplier but hasn’t recorded it:

Dr. Purchase Expense A/c   50,000
Cr. Accounts Payable A/c   50,000

## In the Real World

1. Nepal Rastra Bank (NRB) Loan Interest Adjustments

   • Concept: Accrual and Matching.
   • How: NRB records interest on loans monthly, even if received annually. Auditors verify that interest income matches the period of loan usage, not cash receipts.
   • Example: A Rs. 10,00,000 loan at 10% interest (Rs. 83,333/month) must be recorded monthly, not in a lump sum at year-end.

2. Daraz’s Inventory Valuation Errors

   • Concept: Consistency and Materiality.
   • How: Daraz uses FIFO for inventory. If an auditor finds LIFO used in one quarter, they must adjust to FIFO for comparability. A Rs. 5,00,000 discrepancy (material) triggers a rectifying entry:

     Dr. Cost of Goods Sold (COGS)   5,00,000
     Cr. Inventory                   5,00,000
     

3. eSewa’s Transaction Fee Reconciliation

   • Concept: Error of Omission.
   • How: eSewa processes millions of transactions daily. Auditors sample 5% to check for unrecorded fees (e.g., Rs. 20,000 missed in a batch). The adjustment:

     Dr. Accounts Receivable (Customers)   20,000
     Cr. Service Revenue                   20,000
     

4. Ncell’s Depreciation on Cell Towers

   • Concept: Matching and Going Concern.
   • How: Ncell depreciates cell towers over 25 years. If an auditor finds towers undepreciated for 3 years (Rs. 2,00,00,000 cost), the adjustment is:

     Dr. Depreciation Expense   24,00,000 (2,00,00,000 / 25 * 3)
     Cr. Accumulated Depreciation   24,00,000
     

## Exam Tip: How to Score Full Marks

1. For Rectifying Entries (5×2 Marks Questions):

   • Always show T-accounts or journal entries with Dr/Cr columns.
   • State the impact on net income (e.g., "Net income is overstated by Rs. X").
   • Use realistic numbers (e.g., Rs. 20,000, not Rs. 1).

2. For Concept Applications (3+6 Marks Questions):

   • Define the concept first (e.g., "Accrual concept means...").
   • Link it to audit procedures (e.g., "Auditors verify accrued interest by...").
   • Give a Nepali business example (e.g., "NRB’s loan interest").

3. For Adjustment Impacts (5 Marks Questions):

   • Show before and after financial statement effects.
   • Example:

     "If depreciation was omitted, assets are overstated by Rs. X, and net income is overstated by Rs. X."

4. Avoid Common Mistakes:

   • ❌ Writing "Dr. To Cr." without amounts.
   • ❌ Ignoring the date (always use 2023-12-31 for year-end adjustments).
   • ❌ Forgetting to total Dr/Cr columns.

## Worked Example: Full Audit Adjustment Scenario

Business: Thamel Café (a Kathmandu-based restaurant) Issues Found by Auditor:

1. Rent Prepaid: Rs. 60,000 paid in 2023 for 2024 was recorded as rent expense.
2. Salaries Accrued: Rs. 40,000 for December salaries was unrecorded.
3. Equipment Depreciation: A Rs. 2,00,000 mixer (5-year life) had no depreciation in 2023.

Solution:

1. Rent Adjustment:

   • 2023’s share: Rs. 30,000 (half of Rs. 60,000).
   • Journal:

     Dr. Prepaid Rent       30,000
     Cr. Rent Expense      30,000
     

2. Salaries Adjustment:

   • Journal:

     Dr. Salaries Expense  40,000
     Cr. Salaries Payable  40,000
     

3. Depreciation Adjustment:

   • Annual depreciation: Rs. 40,000 (2,00,000 / 5).
   • Journal:

     Dr. Depreciation Expense  40,000
     Cr. Accumulated Depreciation  40,000
     

Impact on Net Income:

• Increase: Rs. 40,000 (salaries) + Rs. 40,000 (depreciation) = +Rs. 80,000.
• Decrease: Rs. 30,000 (rent) = -Rs. 30,000.
• Net Effect: +Rs. 50,000 (net income was understated).
