Accounting Principles & Concepts: Rules, Assumptions & Real-World Applications

Core Accounting Principles (GAAP) and Concepts

1. Basic Definitions

Accounting principles are rules that guide how transactions are recorded, while concepts are assumptions about the nature of business activities. Together, they ensure consistency and reliability in financial statements.

Key Terms:

• GAAP (Generally Accepted Accounting Principles): Standardized rules for financial reporting (e.g., consistency, materiality).
• Concepts: Underlying assumptions (e.g., accrual basis, going concern).
• Conventions: Common practices (e.g., conservatism, full disclosure).

3. How These Principles Work in Practice

Example: Kathmandu Restaurant’s Daily Transactions

Scenario: Thamel Bhoj restaurant (NPR 200,000 daily sales) records the following in one day:

1. Purchased NPR 50,000 worth of vegetables on credit from a supplier.
2. Received NPR 80,000 cash from dinner sales.
3. Paid NPR 15,000 rent for the month (prepaid).
4. Bought a new oven for NPR 200,000 (paid 50% cash, 50% on credit).

T-Accounts (Dual Aspect Visualization)

Key Observations:

• Dual Aspect: Every debit has a corresponding credit (e.g., Cash Dr 80,000 | Sales Cr 80,000).
• Accrual Basis: Rent is recorded as an expense over time (not all at once), and the oven is capitalized as an asset.
• Business Entity: The owner’s personal cash is not mixed with the restaurant’s Cash account.

4. Accounting Cycle Flowchart

In the Real World

1. eSewa (Nepal)

   • Principle Used: Realization and Accrual Basis
   • How: eSewa records revenue when a transaction is completed (e.g., electricity bill payment), not when cash is deposited into their bank account. This ensures accurate reporting of daily sales.

2. Pathao (Ride-Hailing App)

   • Principle Used: Matching and Conservatism
   • How: Pathao matches driver commissions (expenses) with ride revenues in the same period. If a rider disputes a fare, Pathao records the amount as a liability (conservatism) until resolved.

3. Nepal Rastra Bank (NRB) Audits

   • Principle Used: Full Disclosure and Consistency
   • How: NRB requires banks (e.g., NMB, Global IME) to disclose all loan defaults and interest rate changes consistently. For example, if a bank changes its loan interest calculation method, it must explain this in its annual report.

4. Hotel Everest (Kathmandu)

   • Principle Used: Business Entity and Cost
   • How: The hotel’s fixed assets (e.g., beds, AC units) are recorded at purchase cost, not resale value. The owner’s personal car is never recorded in the hotel’s ledger.

5. Worked Example: Daraz Seller’s Inventory

Scenario: Seller "Nepal Treasures" sells handmade carpets. On May 1, they:

• Buy 10 carpets at NPR 5,000 each (total NPR 50,000) on credit.
• Sell 5 carpets for NPR 8,000 each (total NPR 40,000) on credit.
• Pay NPR 20,000 for delivery charges in cash.

T-Accounts

Key Takeaways:

• Accrual Basis: Revenue (NPR 40,000) is recorded when carpets are sold, not when cash is received.
• Matching: Delivery charges (NPR 20,000) are matched with the sales revenue of the same period.
• Business Entity: The seller’s personal expenses (e.g., lunch) are not recorded here.

6. Common Mistakes and How to Avoid Them

Exam Tip

How This Unit is Tested in TU Exams

1. Definitions (5-10 marks)

   • Expect questions like: "Define ‘Accrual Basis’ with an example from a Kathmandu hotel."
   • Answer Tip: Always give a real-world example (e.g., "A hotel records room revenue when guests check out, not when they pay in advance").

2. Journal Entries (15-20 marks)

   • Common Scenarios:
     • Mixed transactions (cash + credit).
     • Prepaid/accrued expenses.
     • Sales returns or discounts.
   • Marks Distribution:
     • Correct accounts (5 marks).
     • Correct Dr/Cr sides (5 marks).
     • Narration (3 marks).
     • Totals (2 marks).
   • Example Question: "Journalize the following for a travel agency: 1. Received NPR 50,000 advance for a group tour. 2. Paid NPR 20,000 for flight tickets (to be used next month)."
   • Solution:

     | **Date**   | **Particulars**               | **Dr (NPR)** | **Cr (NPR)** |
     |------------|-------------------------------|--------------|--------------|
     | 2024-05-10 | Cash A/c                       | 50,000       |              |
     |            | To Advance from Customers A/c   |              | 50,000       |
     | 2024-05-10 | Prepaid Flight Tickets A/c    | 20,000       |              |
     |            | To Cash A/c                   |              | 20,000       |
     

3. Concept Application (10 marks)

   • Example Question: "How does the Matching Principle apply to a restaurant’s monthly financial statements?"
   • Answer Tip:
     • "Food costs incurred in May are matched with May’s sales revenue, not prepaid or deferred to June."

4. Short Notes (5 marks each)

   • Common Topics:
     • Dual Aspect Concept.
     • Conservatism vs. Optimism.
     • Difference between Revenue Recognition and Cash Realization.
   • Example Answer:

     Dual Aspect Concept: Every financial transaction has two equal and opposite effects. For example, buying furniture for NPR 100,000 debits the Furniture Account (asset ↑) and credits the Cash or Supplier Account (asset/liability ↓).

5. Case Studies (20 marks)

   • Example Scenario: "A travel agency’s books show: - Cash: NPR 200,000 - Unrecorded tour commissions: NPR 50,000 (earned but not yet received) - Prepaid insurance: NPR 30,000 (for 6 months) Prepare the corrected Cash Book using accrual accounting."
   • Solution Steps:
     1. Add unrecorded commissions (Dr Commissions Receivable, Cr Commissions Revenue).
     2. Allocate prepaid insurance (Dr Insurance Expense, Cr Prepaid Insurance).

Final Checklist for Full Marks

• Always use real Nepali business examples (hotels, travel agencies, e-commerce).
• Label every T-account and journal entry clearly.
• Explain why a principle is applied (e.g., "We use accrual basis to match expenses with revenues").
• Show workings for adjustments (e.g., prepaid rent allocation).
• Avoid mixing cash and accrual basis in the same answer.
