3. Profitability Ratios | 盈利能力比率
Profitability ratios gauge how effectively the business converts sales into profits. We will compute the gross profit margin, operating profit margin and net profit margin.
盈利能力比率衡量企业将销售转化为利润的效率。我们将计算毛利率、营业利润率和净利率。
The gross profit margin fell from 42% in 2022 to 40% in 2023. This signals that cost of sales is growing faster than revenue, possibly due to higher raw material prices or aggressive discounting.
毛利率从2022年的42%下降至2023年的40%，表明销售成本的增长快于收入，可能缘于原材料价格上涨或激进打折。
Gross Profit Margin = (Gross Profit ÷ Revenue) × 100% = (480 ÷ 1,200) × 100% = 40%
毛利率 = (毛利 ÷ 收入) × 100% = (480 ÷ 1,200) × 100% = 40%
The operating profit margin remained stable at 20% in 2023 (2022: 21%). Management have controlled operating expenses reasonably well despite revenue growth of 20%.
营业利润率在2023年稳定在20%（2022年为21%）。在收入增长20%的情况下，管理层对营业费用的控制还算不错。
Operating Profit Margin = (Operating Profit ÷ Revenue) × 100% = (240 ÷ 1,200) × 100% = 20%
营业利润率 = (营业利润 ÷ 收入) × 100% = (240 ÷ 1,200) × 100% = 20%
Net profit margin declined from 15.2% to 14.0%. The increased interest charge (from £20,000 to £30,000) eroded bottom-line profitability, a direct consequence of higher borrowing.
净利率由15.2%下降至14.0%。增加的利息费用（从20,000英镑升至30,000英镑）侵蚀了最终盈利能力，这是借款上升的直接后果。
Net Profit Margin = (Profit for the Year ÷ Revenue) × 100% = (168 ÷ 1,200) × 100% = 14.0%
净利率 = (年度利润 ÷ 收入) × 100% = (168 ÷ 1,200) × 100% = 14.0%
4. Liquidity Ratios | 流动性比率
Liquidity ratios assess the company’s ability to meet short-term obligations as they fall due. Two key measures are the current ratio and the acid-test (quick) ratio.
流动性比率衡量企业偿付到期短期债务的能力。两个关键指标是流动比率和速动比率（酸性测试比率）。
The current ratio edged down from 1.70:1 to 1.67:1. It remains well above 1, indicating sufficient current assets to cover current liabilities, but the slight erosion warrants attention.
流动比率从1.70:1小幅下滑至1.67:1。它仍远高于1，表明流动资产足以覆盖流动负债，但轻微的恶化值得关注。
Current Ratio = Current Assets ÷ Current Liabilities = 400 ÷ 240 = 1.67 : 1
流动比率 = 流动资产 ÷ 流动负债 = 400 ÷ 240 = 1.67 : 1
The acid-test ratio fell more noticeably from 1.10:1 to 1.04:1. Excluding inventory, the liquid assets barely cover immediate obligations. A ratio close to 1 suggests minimal safety buffer, especially if the bank overdraft creates daily liquidity pressure.
速动比率更为明显地由1.10:1降至1.04:1。剔除存货后，速动资产勉强覆盖即时债务。比率接近1表明安全缓冲极小，尤其银行透支会带来日常流动性压力。
Acid-Test Ratio = (Current Assets − Inventory) ÷ Current Liabilities = (400 − 150) ÷ 240 = 1.04 : 1
速动比率 = (流动资产 − 存货) ÷ 流动负债 = (400 − 150) ÷ 240 = 1.04 : 1
5. Efficiency Ratios | 效率比率
Efficiency ratios reveal how well the company manages its inventory, receivables and payables. These directly impact cash flow and working capital.
效率比率揭示企业管理存货、应收账款和应付账款的能力，直接影响现金流和营运资金。
Inventory turnover days increased slightly from 76 days to 76 days (effectively unchanged). The firm held £150,000 of inventory on cost of sales of £720,000, mirroring the previous year’s stock velocity. No improvement suggests dormant or slow-moving items may exist.
存货周转天数轻微上升，从76天变为76天（基本持平）。公司持有150,000英镑存货，对应720,000英镑销售成本，与上年库存周转速度相同。没有改善暗示可能存在呆滞或滞销存货。
Inventory Turnover (days) = (Inventory ÷ Cost of Sales) × 365 = (150 ÷ 720) × 365 ≈ 76 days
存货周转天数 = (存货 ÷ 销售成本) × 365 = (150 ÷ 720) × 365 ≈ 76 天
Trade receivable days improved from 65.7 days to 60.8 days. Collecting debts faster is a positive sign, boosting cash inflow and reducing the risk of bad debts.
应收账款周转天数从65.7天改善至60.8天。收回欠款更快是一个积极信号，有助于现金流入并降低坏账风险。
Receivable Days = (Trade Receivables ÷ Revenue) × 365 = (200 ÷ 1,200) × 365 ≈ 60.8 days
应收账款周转天数 = (应收账款 ÷ 收入) × 365 = (200 ÷ 1,200) × 365 ≈ 60.8 天
Trade payable days reduced from 88.1 days to 81.1 days. Paying suppliers more quickly can strengthen relationships, but it also consumes cash and worsens the operating cash cycle unless offset by the improvement in receivables.
应付账款周转天数从88.1天缩短至81.1天。更快支付供应商有助于加固关系，但也会消耗现金并恶化经营现金周期，除非被应收天数的改善所抵消。
Payable Days = (Trade Payables ÷ Cost of Sales) × 365 = (160 ÷ 720) × 365 ≈ 81.1 days
应付账款周转天数 = (应付账款 ÷ 销售成本) × 365 = (160 ÷ 720) × 365 ≈ 81.1 天
The combined effect means the cash conversion cycle (inventory days + receivable days − payable days) shortened from about 54 days to 56 days, a modest deterioration. Overall, efficiency is acceptable but not outstanding.
综合影响意味着现金转换周期（存货天数 + 应收天数 − 应付天数）从约54天变为56天，出现轻微恶化。总体而言，效率尚可但并不突出。
6. Gearing and Risk | 杠杆与风险
Gearing measures the proportion of a company’s capital that is financed by debt. High gearing increases financial risk because interest must be paid regardless of profit levels.
杠杆比率衡量公司资本中由债务融资的比例。高杠杆会增加财务风险，因为无论利润水平如何都必须支付利息。
The gearing ratio, calculated as non-current liabilities over total capital employed (equity + non-current liabilities), rose from 28.6% to 31.3%. This shift towards debt financing amplifies the impact of profit changes on returns to shareholders.
杠杆比率按非流动负债除以总运用资本（股权 + 非流动负债）计算，从28.6%上升至31.3%。这种向债务融资的倾斜放大了利润变动对股东
