📚 A-Level CAIE Accounting: Case Study Practice Walkthrough | A-Level CAIE 会计：案例分析实战演练
Case study questions in CAIE A-Level Accounting (9706) test your ability to apply accounting concepts, analyse financial data, and justify business decisions in a realistic scenario. This walkthrough uses a fictional company, Aurora Ltd, to demonstrate how to move from raw data to structured evaluation under exam conditions.
CAIE A-Level 会计（9706）的案例分析题考查你在真实情境中应用会计概念、分析财务数据并论证经营决策的能力。本文以虚构公司 Aurora Ltd 为例，演示如何在考试条件下从原始数据过渡到结构化评价。
1. Understanding the Case Study Requirements | 理解案例分析要求
Before touching numbers, read the requirement carefully. CAIE case studies typically ask you to calculate ratios, prepare budgets or statements, and then evaluate performance or recommend a course of action. Identify command words such as calculate, assess, recommend and evaluate, because they carry different mark allocations and depth.
在动笔计算之前，必须仔细阅读题目要求。CAIE 案例分析通常要求你计算比率、编制预算或报表，然后评价业绩或提出行动建议。要识别 calculate、assess、recommend、evaluate 等指令词，因为它们的分值分配和作答深度不同。
Allocate time in proportion to marks. If a 12-mark evaluation follows a 10-mark calculation, do not spend twenty minutes perfecting the table format. Use the case information to support every judgement, not just to list figures.
时间分配应与分值成比例。如果 10 分的计算题之后是 12 分的评价题，就不要花二十分钟去完善表格格式。每个判断都要用案例信息作支撑，而不是仅仅罗列数字。
2. Presenting Aurora Ltd’s Financial Data | 呈现 Aurora Ltd 的财务数据
The extracts below from Aurora Ltd provide the basis for ratio analysis. Always check whether figures are in £000 or full pounds before you start.
以下 Aurora Ltd 的财务数据摘录为比率分析提供基础。开始前务必确认数字单位是千英镑还是完整英镑。
| Item | 2024 | 2023 |
|---|---|---|
| Revenue | 480,000 | 400,000 |
| Cost of sales | 288,000 | 220,000 |
| Gross profit | 192,000 | 180,000 |
| Operating expenses | 96,000 | 84,000 |
| Operating profit | 96,000 | 96,000 |
| Inventory | 36,000 | 28,000 |
| Trade receivables | 48,000 | 40,000 |
| Cash | 8,000 | 12,000 |
| Total current assets | 92,000 | 80,000 |
| Trade payables | 30,000 | 26,000 |
| Bank overdraft | 10,000 | 8,000 |
| Total current liabilities | 40,000 | 34,000 |
| Equity | 230,000 | 210,000 |
| 10% Loan | 40,000 | 30,000 |
| Capital employed | 270,000 | 240,000 |
In an exam, you would often be given only some of these figures. Your first task is to select the items needed for each formula, not to rewrite the entire statement.
在考试中，通常只会给出其中部分数据。你的首要任务是选出每个公式所需的项目，而不是重写整张报表。
3. Profitability Ratios in Action | 盈利能力比率实战
For Aurora Ltd, the gross margin and net margin reveal how profit is affected by cost control. The gross margin fell from 45.0% to 40.0%, even though revenue increased by 20%.
以 Aurora Ltd 为例，毛利率和净利率可以揭示成本控制对利润的影响。尽管收入增长了 20%，毛利率却从 45.0% 下降到 40.0%。
Gross margin 2024 = 192,000 ÷ 480,000 × 100 = 40.0%
Gross margin 2023 = 180,000 ÷ 400,000 × 100 = 45.0%
The decline is caused by cost of sales rising faster than revenue: cost of sales grew by 30.9% while revenue grew by 20%. This could indicate higher purchase prices, inventory wastage or a change in sales mix.
毛利率下降的原因是销售成本增速快于收入：销售成本增长了 30.9%，而收入只增长了 20%。这可能表明采购价格上涨、存货损耗或销售结构发生变化。
Net margin also dropped from 24.0% to 20.0%. Operating profit remained static at £96,000, so the fall in net margin reflects the dilution of fixed operating expenses over higher revenue but a sharper increase in variable operating costs.
净利率也从 24.0% 下降到 20.0%。经营利润保持在 96,000 英镑，因此净利率下降说明固定经营费用被更高收入稀释的同时，变动经营成本上升得更快。
ROCE 2024 = 96,000 ÷ 270,000 × 100 = 35.6%
ROCE 2023 = 96,000 ÷ 240,000 × 100 = 40.0%
Return on capital employed fell because capital employed increased through higher equity and loan finance, while operating profit did not grow. This is a key warning signal for management and investors.
资本报酬率下降，是因为资本占用额因权益和贷款增加而上升，而经营利润没有增长。这对管理层和投资者都是一个重要的警示信号。
4. Liquidity and Working Capital Analysis | 流动性与营运资本分析
Liquidity ratios show whether Aurora Ltd can meet its short-term obligations. The current ratio was 2.35:1 in 2023 and 2.30:1 in 2024, while the quick ratio fell from 1.53:1 to 1.40:1.
流动性比率可以说明 Aurora Ltd 是否能偿还短期债务。流动比率 2023 年为 2.35:1，2024 年为 2.30:1；速动比率从 1.53:1 下降到 1.40:1。
Current ratio 2024 = 92,000 ÷ 40,000 = 2.30:1
Acid test 2024 = (92,000 − 36,000) ÷ 40,000 = 1.40:1
Both ratios remain above conventional safety levels, so short-term solvency is not an immediate problem. However, the downward trend is caused by inventory rising from £28,000 to £36,000 while cash falls from £12,000 to £8,000.
两个比率都高于通常的安全水平，因此短期偿债能力没有迫在眉睫的问题。但下降趋势的原因是存货从 28,000 英镑增加到 36,000 英镑，而现金从 12,000 英镑减少到 8,000 英镑。
An increase in inventory ties up cash and may indicate slower sales. If the trend continues, Aurora Ltd may need to arrange a larger overdraft or improve inventory control.
存货增加会占用现金，并可能表明销售放缓。如果这种趋势持续，Aurora Ltd 可能需要安排更大的透支额度或加强存货控制。
5. Efficiency Ratios and Interpretation | 效率比率与解读
Efficiency ratios measure how well Aurora Ltd uses its assets. Inventory turnover improved slightly from 8.8 times in 2023 to 9.0 times in 2024, using average inventory as required.
效率比率衡量 Aurora Ltd 使用资产的效率。按平均存货计算，存货周转率从 2023 年的 8.8 次略微提高到 2024 年的 9.0 次。
Inventory turnover 2024 = 288,000 ÷ ((28,000 + 36,000) ÷ 2) = 9.0 times
Trade receivable days remained stable at 36.5 days in both years. This suggests credit control is consistent, but management should check whether the credit period allowed to customers is 30 or 45 days.
应收账款周转天数两年均保持在 36.5 天。这表明信用控制政策一致，但管理层应检查给予客户的信用期是 30 天还是 45 天。
Receivable days 2024 = 48,000 ÷ 480,000 × 365 = 36.5 days
Trade payable days fell from 43.1 days to 38.0 days. Aurora Ltd is paying suppliers faster than before, which may improve supplier relationships but also puts extra pressure on cash.
应付账款周转天数从 43.1 天下降到 38.0 天。Aurora Ltd 支付供应商的速度比以前更快，这可能会改善供应商关系，但也会给现金带来额外压力。
6. Investment Appraisal for a Proposed Project | 拟议项目的投资评估
Aurora Ltd is considering purchasing new machinery for £120,000. The machine has a five-year life and a residual value of £10,000. Expected net cash flows are £25,000 in Year 1, £35,000 in Year 2, £40,000 in Year 3, £30,000 in Year 4 and £25,000 in Year 5.
Aurora Ltd 正在考虑购买一台价值 120,000 英镑的新机器。该机器使用寿命为五年，残值为 10,000 英镑。预计净现金流量为第 1 年 25,000 英镑、第 2 年 35,000 英镑、第 3 年 40,000 英镑、第 4 年 30,000 英镑和第 5 年 25,000 英镑。
Payback period is found by accumulating cash flows until the initial investment is recovered. After Year 3, £100,000 has been recovered, leaving £20,000 to be recovered in Year 4.
回收期通过累计现金流量直至收回初始投资来确定。第 3 年后已收回 100,000 英镑，第 4 年还需收回 20,000 英镑。
Payback = 3 + (120,000 − 25,000 − 35,000 − 40,000) ÷ 30,000 = 3.67 years
Accounting rate of return uses average annual profit and average investment. Total cash inflows are £155,000 and total depreciation is £110,000, giving total profit of £45,000 over five years.
会计收益率使用平均年利润和平均投资额。总现金流入为 155,000 英镑，总折旧为 110,000 英镑，五年总利润为 45,000 英镑。
ARR = [(155,000 − 110,000) ÷ 5] ÷ [(120,000 + 10,000) ÷ 2] × 100 = 13.85%
Net present value at a 10% discount rate is negative £2,310, as shown by discounting each cash flow at 10%.
按 10% 折现率计算的净现值为负 2,310 英镑，如下所示将各年
