2. Profitability Analysis | 盈利能力分析

Gross profit margin = (Gross Profit / Revenue) × 100 = (800,000 / 2,000,000) × 100 = 40%. This indicates a strong ability to control direct production costs; for a manufacturer, a 40% margin is generally considered healthy.

毛利率 = (毛利 / 收入) × 100 = (800,000 / 2,000,000) × 100 = 40%。这表明公司控制直接生产成本的能力较强；对于制造企业，40% 的毛利率通常被认为是健康的。

Operating profit margin = (Operating Profit / Revenue) × 100 = (400,000 / 2,000,000) × 100 = 20%. The decline from gross margin shows that operating expenses consume half of the gross profit, highlighting room for better overhead control.

营业利润率 = (营业利润 / 收入) × 100 = (400,000 / 2,000,000) × 100 = 20%。从毛利率到营业利润率的下降说明营业费用消耗了一半的毛利，反映出在管理费用控制上仍有改善空间。

Return on capital employed (ROCE) = (Operating Profit / Capital Employed) × 100. Capital employed = Total assets − Current liabilities = 2,100,000 − (200,000 + 100,000) = 1,800,000. ROCE = 400,000 / 1,800,000 × 100 = 22.2%. This exceeds a typical bank interest rate, suggesting efficient use of long-term funds.

已用资本回报率 (ROCE) = (营业利润 / 已用资本) × 100。已用资本 = 总资产 − 流动负债 = 2,100,000 − (200,000 + 100,000) = 1,800,000。ROCE = 400,000 / 1,800,000 × 100 = 22.2%。该回报率高于典型的银行贷款利率，表明长期资金运用有效。

3. Liquidity and Efficiency | 流动性与效率

Current ratio = Current Assets / Current Liabilities = (250,000 + 300,000 + 50,000) / (200,000 + 100,000) = 600,000 / 300,000 = 2 : 1. This is comfortable and shows the business has twice as many short-term assets as obligations.

流动比率 = 流动资产 / 流动负债 = (250,000 + 300,000 + 50,000) / (200,000 + 100,000) = 600,000 / 300,000 = 2 : 1。这个水平较为理想，表明公司流动资产是短期债务的两倍。

Quick ratio (acid test) = (Current Assets − Inventory) / Current Liabilities = (600,000 − 250,000) / 300,000 = 1.17 : 1. Removing inventory still leaves a safe buffer, showing the company is not over-reliant on slow-moving stock.

速动比率 = (流动资产 − 存货) / 流动负债 = (600,000 − 250,000) / 300,000 = 1.17 : 1。扣除存货后仍有安全缓冲，反映出公司没有过度依赖周转慢的库存。

Inventory turnover (days) = (Inventory / Cost of Sales) × 365 = (250,000 / 1,200,000) × 365 = 76 days. Trade receivables days = (Receivables / Revenue) × 365 = (300,000 / 2,000,000) × 365 = 55 days. Trade payables days = (Payables / Cost of Sales) × 365 = (200,000 / 1,200,000) × 365 = 61 days. The operating cycle is 76 + 55 − 61 = 70 days, indicating cash is tied up for over two months before being recovered.

存货周转天数 = (存货 / 销售成本) × 365 = (250,000 / 1,200,000) × 365 = 76 天。应收帐款周转天数 = (应收帐款 / 收入) × 365 = (300,000 / 2,000,000) × 365 = 55 天。应付帐款周转天数 = (应付帐款 / 销售成本) × 365 = (200,000 / 1,200,000) × 365 = 61 天。经营周期为 76 + 55 − 61 = 70 天，这意味着资金被占用超过两个月才能回笼。管理层或可寻求缩短存货和应收款周期，以释放现金。

4. Investment Appraisal: Payback & ARR | 投资评估：回本期与会计收益率

TechGear Ltd. is considering investing £120,000 in a new production line. Estimated net cash inflows are: Year 1 £30,000; Year 2 £40,000; Year 3 £50,000; Year 4 £30,000; Year 5 £20,000 plus a residual value of £10,000. Straight-line depreciation applies.

TechGear Ltd. 拟投资 £120,000 购入一条新生产线。预计净现金流入如下：第 1 年 £30,000；第 2 年 £40,000；第 3 年 £50,000；第 4 年 £30,000；第 5 年 £20,000，另有残值 £10,000。采用直线法计提折旧。

Payback period: Cumulative cash flows become positive during Year 3. By end of Year 2, cumulative outflow is £50,000 (120,000 − 30,000 − 40,000). The Year 3 inflow of £50,000 exactly covers the remaining £50,000, so payback = 2 + (50,000 / 50,000) = 3 years. This is a simple measure of risk; the sooner the initial outlay is recovered, the lower the exposure.

回本期：累计现金流在第 3 年转为正值。第 2 年末累计流出 £50,000 (120,000 − 30,000 − 40,000)。第 3 年流入 £50,000 恰好弥补剩余 £50,000，因此回本期 = 2 + (50,000 / 50,000) = 3 年。这是一个简单的风险衡量指标；初始投资收回得越快，风险敞口越小。

Accounting Rate of Return (ARR): Total depreciation = (120,000 − 10,000) / 5 = £22,000 per year. Total cash inflows over 5 years = 30,000 + 40,000 + 50,000 + 30,000 + 20,000 = £170,000. Total profit = 170,000 − (5 × 22,000) = £60,000. Average annual profit = 60,000 / 5 = £12,000. Average investment = (120,000 + 10,000) / 2 = £65,000. ARR = (12,000 / 65,000) × 100 = 18.5%. This exceeds the company’s target hurdle rate of 15%, making the project attractive under the ARR method.

会计收益率 (ARR)：总折旧 = (120,000 − 10,000) / 5 = 每年 £22,000。五年总现金流入 = 30,000 + 40,000 + 50,000 + 30,000 + 20,000 = £170,000。总利润 = 170,000 − (5 × 22,000) = £60,000。平均年利润 = 60,000 / 5 = £12,000。平均投资 = (120,000 + 10,000) / 2 = £65,000。ARR = (12,000 / 65,000) × 100 = 18.5%。这超过了公司 15% 的目标回报率，因此从 ARR 角度看该项目可行。

5. Net Present Value (NPV) Analysis | 净现值分析

Using a discount rate of 10%, the discount factors are: Y1 0.909, Y2 0.826, Y3 0.751, Y4 0.683, Y5 0.621. Calculate the present value of each cash flow including the residual value at Year 5.

使用 10% 的折现率，各年折现因子为：第 1 年 0.909，第 2 年 0.826，第 3 年 0.751，第 4 年 0.683，第 5 年 0.621。计算包含第 5 年残值的各笔现金流现值。

PV = 30,000×0.909 + 40,000×0.826 + 50,000×0.751 + 30,000×0.683 + (20,000+10,000)×0.621

Present value of inflows = 27,270 + 33,040 + 37,550 + 20,490 + 18,630 = £137,980. NPV = Total PV − Initial Investment = 137,980 − 120,000 = £17,980. A positive NPV means the project increases shareholder wealth and should be accepted.

流入现值 = 27,270 + 33,040 + 37,550 + 20,490 + 18,630 = £137,980。NPV = 总现值 − 初始投资 = 137,980 − 120,000 = £17,980。正的净现值表明该项目将增加股东财富，应予接受。

The NPV method is preferred in theory because it accounts for the time value of money and considers all cash flows over the project’s life. The result reinforces the ARR signal that the expansion is financially viable.

理论上 NPV 法更受推崇，因为它考虑了货币时间价值以及项目整个生命期的全部现金流。该结果印证了 ARR 所表明的扩张项目在财务上可行的信号。

6. Budgetary Control & Standard Costing | 预算控制与标准成本分析

TechGear uses a flexible budgeting system. During the period, actual production was 5,000 units, compared to a budgeted 4,800 units. The standard direct material cost is £5 per kg, with a standard usage of 2 kg per unit. Actual material purchased and used was 11,000 kg at a cost of £5.20 per kg.

TechGear 采用弹性预算制度。当期实际产量为 5,000 件，而预算产量为 4,800 件。标准直接材料成本为每公斤 £5，每件标准用量为 2 公斤。实际采购并耗用材料 11,000 公斤，价格为每公斤 £5.20。

Material Price Variance = (Standard Price − Actual Price) × Actual Quantity = (5 − 5.20) × 11,000 = −£2,200 Adverse.

材料价格差异 = (标准价格 − 实际价格) × 实际用量 = (5 − 5.20) × 11,000 = −£2,200 不利差异。

Material Usage Variance = (Standard Quantity for Actual Output − Actual Quantity) × Standard Price = (5,000×2 − 11,000) × 5 = (10,000 − 11,000) × 5 = −£5,000 Adverse.

材料用量差异 = (实际产量下的标准用量 − 实际用量) × 标准价格 = (5,000×2 − 11,000) × 5 = (10,000 − 11,000) × 5 = −£5,000 不利差异。

Both variances are adverse, suggesting the purchasing department may have paid too much and the production department may have been wasteful. A total material cost variance of £7,200 adverse must be investigated immediately.

两个差异均为不利差异，表明采购部门可能支付了过高的价格，而生产部门可能存在浪费。£7,200 的不利材料总成本差异需要立即调查。

7. Relevant Costing: Make or Buy Decision | 相关成本决策：自制还是外购

TechGear currently manufactures a component internally. The unit cost is: direct material £8, direct labour £12, variable overhead £4, and fixed overhead allocation £6, giving a total of £30. An external supplier offers the same component at £28 per unit. If the component is bought externally, only £1 of the fixed overhead can be avoided; the remaining £5 is an unavoidable common cost.

TechGear 目前自制一种零件。其单位成本为：直接材料 £8，直接人工 £12，变动制造费 £4，分摊固定制造费 £6，合计 £30。外部供应商报价 £28 / 件。若
