1. Capital vs. Revenue Expenditure Confusion | 混淆资本支出与收入支出

A frequent mistake is treating a revenue expense (e.g., repairs that maintain an asset) as capital expenditure, or vice versa. The error distorts the statement of profit or loss and the statement of financial position. Capital expenditure creates or enhances a non-current asset; revenue expenditure relates to day-to-day running costs or repairs that merely restore the asset to its original condition.

常见错误是将收入性支出（如维持资产正常使用的修理费）错误地资本化，或者反过来。这会扭曲利润表和财务状况表。资本支出用于获取或提升非流动资产；收入支出则涉及日常经营费用或仅恢复资产原状的修理支出。

Correct any repairs that merely maintain the asset – charge to the income statement as an expense in the period incurred.
将仅维持资产状态的修理费用，作为当期费用计入利润表。
When an extension or significant upgrade adds value or extends useful life, capitalize the cost – add to the non-current asset account.
若扩建或重大升级增加了资产价值或延长使用寿命，将支出资本化，计入非流动资产科目。
If unsure, ask: ‘Does this expenditure bring future economic benefits beyond the current year?’ If yes, it is capital; if not, it is revenue.
难以判断时，可自问：“这笔支出是否会带来超过本年度的未来经济利益？”是则为资本性，否则为收入性。

2. Depreciation Calculation Pitfalls | 折旧计算的陷阱

Students often forget to deduct residual value before applying the straight-line formula, or they incorrectly pro-rate depreciation in the year of purchase or disposal. Another common slip is charging a full year’s depreciation for an asset bought late in the financial year, which contradicts the matching principle.

学生经常在使用直线法前忘记扣除预计净残值，或在购入、处置年度错误计提折旧。另一个常见失误是对财务年度末购入的资产计提全年折旧，这不符合配比原则。

Straight-line formula:

Annual depreciation = (Cost − Residual value) ÷ Useful life
直线法公式：

年折旧额 = (原值 − 预计净残值) ÷ 使用年限
Always deduct residual value first. If using reducing balance method, residual value is ignored in calculation but must be considered for the final written-down value.
必须先扣除残值。若采用余额递减法，计算时忽略残值，但需关注最终账面净值不低于残值。
For part-year depreciation, calculate the annual amount and multiply by the fraction of the year the asset was in use (e.g., bought on 1 October, charge 6/12 if year ends 31 March).
部分年度折旧时，先计算年折旧额，再乘以资产实际使用月数占全年比例（比如10月1日购入，次年3月31日结账，应计6/12年折旧）。
Always read the exam question closely – some specify ‘a full year’s depreciation in the year of purchase’, but OCR typically expects time-apportioned unless otherwise stated.
仔细审题——部分题目可能规定“购置当年提全年折旧”，但OCR考试通常要求按时间分摊，除非明确说明。

3. Bad Debts and Provision for Doubtful Debts Mixed Up | 坏账与坏账准备混淆

Many candidates incorrectly treat a change in the allowance for doubtful debts as an expense in full, forgetting that only the movement is charged to the income statement. Others mistakenly write off a debt against the allowance instead of directly expensing the bad debt and then adjusting the allowance separately.

许多考生将坏账准备的变化额全额计为费用，忘记了只有变动额才计入利润表。也有考生错误地将坏账核销直接冲减准备，而未先将坏账确认为费用再单独调整准备。

Write off a specific bad debt: Dr Bad debts expense, Cr Trade receivables. This is an expense.
核销具体的坏账：借记坏账费用，贷记应收账款。这是一项费用。
The allowance for doubtful debts is then adjusted: compare the required allowance (e.g., 5% of remaining receivables) to the existing allowance. The difference – increase or decrease – goes to the income statement.
然后调整坏账准备：将所需准备（如剩余应收账款的5%）与现有准备比较，差额（增加或减少）计入利润表。
If the allowance increases: Dr Irrecoverable debts expense (income statement), Cr Allowance for doubtful debts (SOFP). If it decreases, the opposite.
准备增加时：借记坏账费用（利润表），贷记坏账准备（资产负债表）。减少则相反。
Do not net off the bad debt write-off against the allowance directly; treat them as two distinct adjustments.
切勿将坏账核销与准备直接抵消；它们是两个独立的调整步骤。

4. Accruals and Prepayments – Reversing the Adjustment | 应计与预付款项的方向错误

One of the simplest yet most damaging errors is adding an accrual when a prepayment is needed, or deducting when an addition was required. This often happens when students incorrectly apply the ‘add, less’ rule from trial balance adjustments.

这是最简单却也最致命的错误之一：需要预付款项时反而加计应计，或应加回时却扣除。考生往往在试算平衡表调整中错误套用“加、减”规则。

Accrual principle: expense incurred but not yet paid – add to the expense in the income statement and show as a current liability.
应计原则：已发生但未支付的费用——在利润表中增加该费用，资产负债表中列为流动负债。
Prepayment: expense paid in advance – deduct from the expense in the income statement and show as a current asset.
预付款项：提前支付的费用——在利润表中从费用中扣除，资产负债表中列为流动资产。
Logic check: if you owe money at year-end, the expense must be higher than the cash paid – so add the accrual. If you have paid in advance, the expense must be lower – so deduct the prepayment.
逻辑验证：年末若存在未付费用，实际费用必然高于已付现金——因此应加上应计；若已预付，实际费用低于支付额——应扣减预付款。
Draw T-accounts for the expense: the debit side shows cash paid (from trial balance) + accrual b/d; the credit side shows prepayment b/d. The balancing figure transferred to income statement is the true expense.
画出费用T型账户：借方为已付现金（来自试算平衡表）+ 期初应付；贷方为期初预付。借贷方平衡后转入利润表的数字即为真实费用。

5. Inventory Valuation – Misusing Net Realisable Value (NRV) | 存货估价中错误应用可变现净值

A misconception is that inventory is always valued at the lower of cost and NRV, but students sometimes compute NRV incorrectly – forgetting selling costs or using estimated selling price without deducting costs to completion. Some also fail to apply the rule on an item-by-item basis, averaging instead which is not permitted under IAS 2.

一种误解是存货始终按成本与可变现净值孰低计价，但学生有时会算错NRV——忘记扣除销售费用，或使用预计售价而未扣除完工尚需成本。还有人将同类存货合并计算，而未逐项比较，这不符合IAS 2的规定。

NRV definition:

NRV = Estimated selling price − Estimated costs to complete − Estimated costs to sell
NRV定义：

NRV = 预计售价 − 预计完工成本 − 预计销售费用
Always compare cost and NRV for each individual line of inventory, not the total. Write down the items that are impaired, never write up.
必须逐项比较成本与NRV，不可按总额计算。仅计提跌价准备，不将存货增值入账。
Common exam scenario: damaged goods. The selling price drops, repair costs are needed – both must be factored into NRV. Often the cost is irrecoverable, so a write-down is needed.
常见考题情景：损毁货物。售价下降，且需要修复费用——两者均应计入NRV计算。通常成本无法收回，需计提跌价。
Stock write-down is debited to cost of sales (or an expense) and credited to inventory on the SOFP.
存货跌价借记销售成本（或单独费用科目），贷记资产负债表中的存货。

6. Statement of Cash Flows – Indirect Method Adjustments | 现金流量表间接法调整错误

The indirect method starts with profit before tax and adjusts for non-cash items and changes in working capital. A typical mistake is adding an increase in trade receivables, or getting the direction wrong for changes in inventory and payables. Students also omit depreciation add-back or mishandle profit/loss on disposal.

间接法从税前利润出发，调整非现金项目和营运资本变动。常见错误是加回应收账款的增加，或错误处理存货和应付账款变动的方向。考生还常遗漏加回折旧，或错误处理处置损益。

Depreciation and amortisation are non-cash expenses – always add back to profit.
折旧与摊销为非现金费用——始终加回至利润。
Working capital logic: an increase in inventories or receivables means cash is tied up – deduct the increase. An increase in payables means cash has been retained – add the increase.
营运资本逻辑：存货或应收账款增加意味着现金被占用——应扣减增加额；应付账款增加意味着现金得以保留——应加计增加额。
Profit on disposal is non-operating and is removed from operating activities (deduct the gain); loss on disposal is added back. The actual sale proceeds appear in investing activities.
处置利润不属于经营活动，应将其从经营利润中扣除；处置亏损则加回。实际出售所得现金计入投资活动部分。
Check the movement figures carefully: closing balance minus opening balance – then apply the correct sign.
仔细核对变动额：期末余额减期初余额——然后按正确方向处理（资产增加则现金流出）。

7. Ratio Analysis – Misinterpreting the Numbers | 比率分析的误读

A high current ratio or acid test ratio is not always favourable; it could indicate excessive inventory or idle cash. Students often comment ‘the higher the better’ without considering industry norms or the composition of current assets. Similarly, they confuse the purpose of profitability ratios with liquidity ratios.

高流动比率或速动比率并不总是好现象，它可能意味着存货积压或资金闲置。考生常评论“越高越好”，却不考虑行业标准或流动资产构成。类似地，他们经常混淆盈利能力比率与流动性比率的作用。

Current ratio = Current assets / Current liabilities. A figure above 2:1 may suggest inefficiency, especially if inventory is slow-moving.
流动比率 = 流动资产 / 流动负债。超过2:1可能暗示低效，尤其是存货周转缓慢时。
Acid test (quick) ratio excludes inventory. A sudden drop might indicate liquidity problems, but a very high ratio could mean cash is not being reinvested.
速动比率剔除存货。突然下降可能预示流动性问题，但过高则可能意味着现金未得到有效再投资。
When evaluating, always link the ratio to the specific business context: a supermarket will have a lower current ratio than a high-tech manufacturer, and that is normal.
评价时，务必结合具体企业背景：超级市场的流动比率通常低于高科技制造商，这完全正常。
Use trends and comparative data over time, not a single snap-shot. Relate gross profit margin to mark-up and inventory turnover for deeper insight.
应使用趋势数据和跨期比较，而非单一截点数据。将毛利率与加成率、存货周转率结合分析，才能得出深入见解。

8. Absorption Costing – Misunderstanding Fixed Production Overheads in Inventory | 吸收成本法下误解存货中的固定制造费用

Under absorption costing, inventory is valued at full production cost including a share of fixed overheads. A common error is to treat all fixed overheads as period costs, as in marginal costing, and thus understate closing inventory value and overstate cost of sales. Another mistake is using budgeted overhead rates without reconciling over/under absorption.

在吸收成本法下，存货按完全生产成本计价，包括分摊的固定制造费用。常见错误是将所有固定费用作为期间成本处理（如边际成本法），从而低估期末存货价值、高估销售成本。另一种错误是使用预算分配率，却不调整多吸收或少吸收的差异。

Closing inventory under absorption costing: Direct materials + Direct labour + Variable production overheads + Fixed production overheads absorbed.
吸收成本法下期末存货包括：直接材料 + 直接人工 + 变动制造费用 + 已吸收的固定制造费用。
If actual fixed overheads differ from absorbed, the under/over absorption goes to the income statement as an adjustment to cost of sales.
若实际固定制造费用与吸收额不等，差额作为销售成本的调整项计入利润表。
Do not confuse with marginal costing, where only variable costs are included in inventory. The difference between the two methods is entirely due to the treatment of fixed overheads in inventory.
切勿与边际成本法混淆，后者存货仅含变动成本。两种方法下利润差异完全源于存货中固定制造费用的处理。
When preparing a reconciliation of profits, remember: Increase in inventory × fixed overhead rate per unit = profit difference.
编制利润调节表时记住：存货增加量 × 每单位固定制造费用吸收率 = 利润差异。

9. Partnership Goodwill – Errors on Admission or Retirement | 合伙商誉在入伙或退伙时的处理错误

When a new partner is admitted or an existing partner retires, goodwill must be valued and adjusted through the capital accounts. Students often credit the new partner’s capital with their share of goodwill without debiting the old partners’ capital accounts in their old profit-sharing ratio, or they forget to write off goodwill entirely after the adjustment.

当新合伙人入伙或原合伙人退伙时，必须评估商誉并通过资本账户进行调整。学生常犯的错误是仅贷记新合伙人资本账户以反映其商誉份额，却未按旧损益分配比例借记原合伙人资本账户，或调整后忘记将商誉全额注销。

Correct double entry for introducing goodwill: Dr Old partners’ capital accounts (old ratio) with the total goodwill, Cr New partner’s capital account with the share of goodwill they bring (or the premium).
引入商誉的正确分录：按原比例借记原合伙人资本账户（总商誉），按其所带入份额（或溢价）贷记新合伙人资本账户。
If the partnership policy is to not maintain a goodwill account, the entry is reversed immediately: Dr New partner’s capital, Cr Old partners’ capital in the new profit-sharing ratio. This eliminates goodwill from the books.
若企业政策是不保留商誉账户，则立即回冲：借记新合伙人资本，按新损益分配比例贷记原合伙人资本。由此账簿中商誉被消除。
On retirement, the retiring partner is compensated for their share of goodwill. Credit their capital account, debit remaining partners’ capital accounts in the new ratio.
退伙时，退伙人按其商誉份额获得补偿。贷记其资本账户，按新比例借记留任合伙人资本账户。
Always double-check the profit-sharing ratios before and after the change – these determine the distribution of goodwill adjustments.
务必核对变更前后的损益分配比例——它们决定了商誉调整的分配。

10. Share Premium and Capital Redemption Reserve – Recording Incorrectly | 股票溢价与资本赎回储备的账务错误

Students often credit the entire proceeds of a share issue to share capital, ignoring the compulsory split between nominal value and share premium under the Companies Act. Similarly, when shares are redeemed out of profits, a transfer to capital redemption reserve is frequently omitted, leading to an incomplete reduction in distributable profits.

学生常将股票发行的全部收款贷记股本，忽略了《公司法》要求的名义价值与股票溢价必须分开处理。类似地，当用利润赎回股份时，常遗漏转入资本赎回储备的分录，导致可分配利润未完整减少。

Issue of shares at a premium: Bank Dr (total cash), Cr Share capital (nominal × number of shares), Cr Share premium (excess over nominal).
溢价发行股票：借记银行存款（全部现金），贷记股本（面值×股数），贷记股票溢价（超过面值部分）。
Share premium is a capital reserve, not distributable as dividends. It can only be used for specific purposes such as bonus issues or writing off preliminary expenses.
股票溢价属于资本储备，不可用于分配股利。只能用于特定用途，如发放红利股或冲销开办费。
On redemption of shares: if financed from profits, record Dr Retained earnings, Cr Capital redemption reserve for the nominal value of shares redeemed. This protects creditors by maintaining capital.
赎回股份时，若用利润支付：按赎回股份面值，借记留存收益，贷记资本赎回储备。这保护了债权人，维持了资本。
If shares are redeemed at a premium, the premium must be charged first against share premium account (if available) or against retained earnings.
若溢价赎回，溢价部分首先冲减股票溢价账户（如有余额），不足部分再冲减留存收益。

11. Non-current Asset Register vs. General Ledger – Reconciliation Errors | 非流动资产登记簿与总账的对账错误

A tricky topic in OCR papers is the reconciliation between the non-current asset register (NCAR) and the nominal ledger control account. Students confuse the direction of additions and disposals, or forget that depreciation in the register must agree with accumulated depreciation in the ledger after adjustments.

OCR考试中一个难点是非流动资产登记簿与总账控制账户的对账。学生常混淆增加与处置的方向，或忘记调整后登记簿上的折旧必须与总账累计折旧一致。

The asset register is a memorandum record listing each asset’s cost, depreciation and carrying amount. The ledger contains control accounts for cost and accumulated depreciation.
资产登记簿是备查记录，逐项列示每个资产的成本、折旧和账面价值。总账中设成本与累计折旧的控制账户。
Start reconciliation with cost: agree opening balances, then add purchases per ledger and per register (check for unrecorded disposals).
对账从成本开始：核对期初余额，然后将总账中的购置与登记簿逐一比对（检查是否有未记录的处置）。
Disposals: ensure the asset removed from the register is also credited to the cost ledger account, while its accumulated depreciation is debited.
处置时确保登记簿中移除的资产，其成本已贷记总账成本账户，且其累计折旧也已借记转出。
Finally, the total accumulated depreciation per the ledger should equal the sum of depreciation for all individual assets in the register after charging the year’s expense.
最后，总账累计折旧总额应等于登记簿中所有单项资产折旧之和（计提当年折旧费用后）。任何差异都需要调查并调整。

12. Income Statement vs. Statement of Financial Position – Misclassification | 利润表与财务状况表的项目错放

It sounds basic, but under exam pressure students place items like drawings, dividends proposed, or even accruals in the wrong statement. Drawings belong to the capital section of the SOFP (or the appropriation account for companies), while dividends proposed after the reporting date are only disclosed in the notes, not accrued.

看似基础，但考试压力下考生会将提款、拟派股利甚至应计项目放错报表。提款属于财务状况表的资本部分（或公司的利润分配表），而报告期后提议的股利仅需在附注中披露，不作应计处理。

For a sole trader or partnership: Drawings are deducted from capital on the SOFP, never in the income statement.
个体户或合伙企业：提款在资产负债表中从资本中扣除，绝不进入利润表。
For a limited company: Dividends paid during the year appear in the statement of changes in equity. Proposed final dividends not yet approved are not recorded as a liability – disclose in the notes per IAS 10.
有限公司：年度内已支付的股利体现在权益变动表中。尚未批准的拟派期末股利不计入负债——依 IAS 10 仅在附注披露。
Accruals (amounts owed) are current liabilities; prepayments are current assets. Loans repayable within 12 months are current liabilities – a classic trap when a long-term loan has a portion due within one year.
应计费用为流动负债；预付款项为流动资产。12个月内到期的贷款属于流动负债——长期贷款中一年内到期部分是经典陷阱。
Always link each item to its accounting definition and the relevant accounting standard. A quick mental checklist: does this item represent an obligation or a resource, and over what time frame?
始终将每个项目与会计定义及相关准则联系。快速自检：该项目代表义务还是资源，时间范围如何？
