Prudence means that profit and assets are not overstated. Possible losses are recognised early, but profits are recognised only once they are realised. It appears in inventory valuation, allowances for doubtful receivables and short explanation questions.
The key skill is to apply prudence to a reasoned figure, not to push every figure down. This lesson belongs to concepts, ethics and changing practice.
What does prudence ask for, and what does it not?
Prudence asks for a cautious but honest estimate. If the evidence says a loss is likely, record it now. If the evidence says goods will sell above cost, do not record the extra profit until they are sold.
Prudence does not ask for the lowest possible figure. Writing inventory down below what the evidence supports creates a hidden reserve, and the accounts then no longer give a fair view of the business.
How to apply prudence to inventory, step by step
- List each item or group with its cost.
- Find the net realisable value (NRV) for each: expected selling price minus any cost needed to sell it, such as repairs.
- Compare cost and NRV for each item.
- Use the lower figure for each item.
- Add up and compare the total with the total cost to find the write-down.
Worked example
Perabot Jaya bought 40 chairs at RM60 each, total RM2,400.
At the year end, 30 chairs are in perfect condition and normally sell for RM90. Ten chairs are damaged. They can be sold for RM45 each after a repair costing RM5 each.
Step 1, damaged chairs NRV: 45 − 5 = RM40 per chair. Cost is RM60, so NRV is lower. Use RM40.
Step 2, good chairs: NRV is RM90, which is above cost of RM60. Use cost, RM60. The extra RM30 profit is not recognised until they are sold.
Step 3, value inventory: 30 × 60 = RM1,800. 10 × 40 = RM400. Total = RM2,200.
Step 4, write-down: cost 2,400 − valuation 2,200 = RM200. This reduces profit for the year.
Receivables in the same business: receivables are RM10,000. A customer owing RM500 is known to be bankrupt, so RM500 is written off as a bad debt. The business estimates 5% of the remaining receivables will not pay. Remaining = 10,000 − 500 = 9,500. Allowance = 9,500 × 5% = RM475.
That is prudent because the 5% comes from a reason, such as past experience, and is applied to the correct balance.
The mistake to watch for
Mistaken answer: “To be prudent, the owner values all 40 chairs at RM30 each, giving inventory of RM1,200.”
The valuation looks cautious but it is not supported by the evidence.
The 30 good chairs cost RM60 and sell for RM90, and the damaged ones have an NRV of RM40. Valuing them at RM30 understates inventory by RM1,000 (2,200 − 1,200) and understates profit by the same amount. That is deliberate understatement, which breaks the fair view.
The correction is to ask, for every figure, “What evidence supports it?” Prudence is about being careful with evidence, not about being as pessimistic as possible.
Check yourself
1. Three items have these values. A: cost RM50, NRV RM70. B: cost RM80, NRV RM65. C: cost RM30, NRV RM30. What is the inventory valuation and the write-down?
Show answer
A: lower of 50 and 70 = 50. B: lower of 80 and 65 = 65. C: 30.
Valuation = 50 + 65 + 30 = RM145. Total cost = 160. Write-down = 160 − 145 = RM15.
2. Receivables are RM8,000. A debt of RM400 is written off as bad. The business wants an allowance of 3% on the remaining receivables. Calculate the allowance.
Show answer
Remaining receivables = 8,000 − 400 = 7,600. Allowance = 7,600 × 3% = RM228.
3. An owner asks the bookkeeper to value all inventory at half of cost so that profit looks lower. Explain why this is not prudence.
Show answer
The figure is not based on evidence of lower selling prices or likely losses. It is a deliberate understatement that makes profit and inventory unreliable. Prudence needs a reasoned estimate, such as lower of cost and NRV.
Where this leads next
Prudence often pulls against other concepts. Continue with identifying a conflict in a reporting scenario, then try the concepts and ethics practice set. The percentage-base explorer helps you check allowance calculations.
Students sometimes know the definition but cannot say which figure it changes. A teacher in online one-to-one Accounting tuition can work from your own answers to close that gap.
