Adjustments: accruals, prepayments, depreciation and bad debts

ZIMSEC O Level · Principles of Accounts · Form 4

Final accounts follow the accruals principle: income and expenses belong to the period in which they are earned or incurred.

Accruals and prepayments

  • Accrued expense (owing): add to the expense; show as a current liability.
  • Prepaid expense (paid in advance): subtract from the expense; show as a current asset.

Worked example: Rent paid during the year was US$2 200 and US$200 is still owing. Insurance paid was US$1 800, of which US$300 is for next year. Find the amounts charged.

Rent = 2 200 + 200 = US$2 400 (accrual 200 under current liabilities)

Insurance = 1 800 − 300 = US$1 500 (prepayment 300 under current assets)

Depreciation

The fall in value of a non-current asset.

  • Straight line: (cost − residual value) ÷ useful life. Cost 10 000, residual 2 000, 4 years → 2 000 per year.
  • Reducing balance: a percentage of the net book value. 20% of 10 000 = 2 000 in year 1; 20% of 8 000 = 1 600 in year 2.

Bad debts and allowance for doubtful debts

  • Bad debts written off are an expense.
  • An allowance for doubtful debts is deducted from receivables; an increase in the allowance is an expense, a decrease is income.
Exam tip: Each adjustment has TWO effects – one in the income statement and one in the statement of financial position.
