1. Confusing Capital and Revenue Expenditure | 混淆资本性支出与收益性支出

A common exam mistake is to treat a repair as a non-current asset when it only restores existing capacity. Capital expenditure brings long-term benefits or improves an asset; revenue expenditure is a day-to-day running cost.

考试中常见的错误是把仅恢复现有产能的维修支出资本化。资本性支出带来长期效益或改良资产，收益性支出属于日常营运成本。

For example, the purchase price, delivery, installation and testing costs of a new machine are capitalised. Annual insurance, fuel and routine repairs are revenue expenses.

例如，新机器的买价、运输、安装和测试成本应当资本化；年度保险费、燃油和日常维修则属于收益性支出。

If a revenue expense is wrongly capitalised, profit and non-current assets are overstated. If a capital expense is expensed, profit is understated.

如果将收益性支出错误资本化，利润和非流动资产会被高估；如果将资本性支出费用化，利润会被低估。

2. Depreciation Methods and Partial-Year Charges | 折旧方法与不足一年折旧

Students often calculate straight-line depreciation on the original cost instead of the depreciable amount. Straight-line depreciation is based on cost minus residual value over useful life.

考生常按原始成本而非应折旧金额计算直线折旧。直线法折旧应按成本减残值后的应折旧金额在可使用年限内分摊。

Annual depreciation = (Cost − Residual value) ÷ Useful life

直线法下，年折旧额 = (成本 − 残值) ÷ 使用寿命。残值不应在折旧基础中被忽略。

When an asset is held for part of a year, depreciation must be prorated by months, unless the accounting policy states a full year charge in the year of purchase and none in the year of disposal.

如果资产在年中购入，折旧必须按月比例计算，除非会计政策规定购入当年计提全年折旧、处置当年不提。

For the reducing balance method, depreciation = Net book value × fixed percentage. After a revaluation, depreciation is based on the revalued amount and remaining useful life.

余额递减法下，折旧 = 账面净值 × 固定百分比；重估后，折旧应根据重估金额和剩余使用年限重新计算。

3. Bad Debts vs Provision for Doubtful Debts | 坏账与坏账准备的区别

A bad debt is a specific receivable that is now uncollectible. It is written off by debiting Bad Debts Expense and crediting Trade Receivables.

坏账是某一笔确定无法收回的应收账款，核销分录为：借 坏账费用，贷 应收账款。

A provision for doubtful debts is an estimate based on the receivables balance. Students often record the full provision amount again instead of recording only the adjustment for the period.

坏账准备是基于应收账款余额的估计。考生常犯的错误是再次记录全部准备金额，而不是只记录本期调整额。

If the provision increases, debit the Income Statement and credit Provision for Doubtful Debts. If it decreases, debit Provision and credit the Income Statement.

如果准备增加，借 利润表（坏账费用），贷 坏账准备；如果准备减少，借 坏账准备，贷 利润表。

4. Inventory Valuation: Lower of Cost and NRV | 存货计价：成本与可变现净值孰低

Inventory must be valued at the lower of cost and net realisable value. NRV is the estimated selling price minus costs to complete and minus selling costs.

存货必须按成本与可变现净值孰低计价。可变现净值等于预计售价减去完工成本和销售费用。

NRV = Estimated selling price − Costs to complete − Selling costs

可变现净值 = 预计售价 − 完工成本 − 销售费用。这一公式是存货计价题的核心。

A frequent error is to use the normal selling price as NRV without deducting selling expenses. Another error is comparing at total inventory level, while CAIE expects item-by-item comparison.

常见错误是把正常售价直接当作可变现净值，未扣减销售费用；另一个错误是按存货总额比较，而 CAIE 要求逐项比较。

Understating closing inventory reduces gross profit and current assets; overstating closing inventory increases them.

期末存货低估会减少毛利和流动资产；期末存货高估则会增加毛利和流动资产。

5. Double-Entry Rules for Expenses and Liabilities | 费用与负债的借贷方向

Many errors come from reversing the double-entry rules. Expenses and assets increase with debits; liabilities, capital and income increase with credits.

许多错误源于借贷方向的颠倒。费用和资产增加记借方，负债、资本和收入增加记贷方。

For example, paying electricity by cheque requires Dr Electricity Expense and Cr Bank. Purchasing goods on credit requires Dr Purchases and Cr Trade Payables.

例如，用支票支付电费：借 电费，贷 银行；赊购商品：借 采购，贷 应付账款。

Remember DEAD CLIC: Debit increases Expenses, Assets and Drawings; Credit increases Liabilities, Income and Capital.

记住 DEAD CLIC：借方增加费用、资产和提款；贷方增加负债、收入和资本。

6. Bank Reconciliation: Which Side to Adjust? | 银行调节表：调整哪一方？

Students often add unpresented cheques to the cash book balance or deduct bank charges from the bank statement balance. The starting point determines the direction of adjustment.

考生常将未兑现支票加到账面余额，或从银行对账单余额中扣减银行手续费。调整方向取决于从哪个余额出发。

To reconcile the bank statement balance to the corrected balance, add lodgements not yet credited and deduct unpresented cheques.

从银行对账单余额调节到修正后余额：加上企业已存银行但
