Fix the numerator before interpreting the answer解释结果前先固定分子
This page uses one explicit convention: quick ratio = (cash + short-term marketable securities + receivables) ÷ current liabilities. Other definitions may start with current assets and subtract inventory and prepayments, or use a narrower cash-and-securities numerator. Those forms are equivalent only when the underlying line items and exclusions are equivalent. The ratio asks how much reported current liability is covered by assets expected to convert without selling inventory. It does not prove that cash is unrestricted, securities can be sold near carrying value, customers will pay receivables promptly, or contract liabilities require cash repayment. Show the exact components, preserve the reported calculation, and place any quality haircut in a separately labeled sensitivity.
本页固定采用一个明确口径：速动比率 =（现金 + 短期可交易证券 + 应收款）÷ 流动负债。其他定义可能从流动资产扣除存货与预付款，或采用更窄的现金加证券分子；只有底层项目与排除项相同，结果才会等价。该比率询问无需出售存货时，报告流动负债有多少能由预期可转化资产覆盖，却不能证明现金不受限、证券可按接近账面价值出售、客户会及时付款，或合同负债必须现金偿还。必须列出准确组成，保留报告计算，并把质量折扣放进单独标记的敏感度。
Choose one numerator before comparing ratios比较前先选择一个分子口径
| Expression | What it includes | Use on this page |
|---|---|---|
| (Cash + short-term marketable securities + receivables) / current liabilities | Named financial and collection assets | Adopted quick ratio |
| (Current assets − inventory − prepayments) / current liabilities | Whatever remains after two exclusions | Cross-check only; equivalent here because no other current asset remains |
| (Cash + short-term marketable securities) / current liabilities | No receivables | A narrower near-cash screen, not called the adopted quick ratio |
| 表达式 | 包含项目 | 本页用途 |
|---|---|---|
| （现金 + 短期可交易证券 + 应收）/ 流动负债 | 已命名金融资产与收款权 | 本页采用的速动比率 |
| （流动资产 − 存货 − 预付款）/ 流动负债 | 扣除两项后剩余的全部项目 | 仅作交叉核对；本案例没有其他流动资产，故结果相同 |
| （现金 + 短期可交易证券）/ 流动负债 | 不含应收 | 更窄的近现金筛查，不称为本页速动比率 |
“Short term” and “marketable” both matter. A current investment is not automatically easy to sell without price concession, while an instrument that trades actively may still be pledged or restricted. Receivables are contractual claims, not cash; net presentation may already include an allowance, but aging and concentration can still dominate conversion. Write down entity, date, currency, units, framework, gross-or-net basis, and every included line before comparing periods or companies.
“短期”与“可交易”两个条件都重要。列为流动的投资不一定能无折价出售，交易活跃的工具也可能已质押或受限。应收是合同收款权，不是现金；净额列报可能已经包含备抵，但账龄与集中度仍可能决定转化结果。比较期间或公司前，应写明主体、日期、币种、单位、框架、总额或净额基础及每个纳入行项目。
A ratio above one can still rely on one troubled customer; a ratio below one can coexist with rapid collections, committed facilities, and predictable supplier terms. Business model, liability timing, concentration, seasonality, and access to funding determine the useful range.
不存在统一阈值比率高于一仍可能依赖一个困难客户；低于一也可能与快速回款、已承诺授信和可预测供应商条款并存。商业模式、负债时点、集中度、季节性与融资渠道共同决定有用区间。

AeroLatch Aviation Parts is a fictional supplier to aircraft maintenance providers. All amounts are invented U.S. dollar millions at December 31, 20X5. The example uses one consolidated entity, one date, one currency, and one policy basis. Cash includes $3m contractually restricted for a facility deposit; receivables are reported net of the fictional accounting allowance.
虚构供应商与固定日期AeroLatch Aviation Parts 是虚构的航空维修零部件供应商。所有金额均为教学假设，单位为百万美元，时点为 20X5 年 12 月 31 日。案例使用同一合并主体、日期、币种与政策基础。现金中有 300 万美元因厂房保证金合同而受限；应收为扣除虚构会计备抵后的报告净额。

Current assets are $18m + $12m + $70m + $75m + $5m = $180m. Current liabilities are $80m, comprising $34m payables, $18m accrued liabilities, $16m current debt, and $12m contract liabilities. Current ratio = $180m / $80m = 2.25. Adopted quick ratio = ($18m + $12m + $70m) / $80m = 1.25. The subtraction cross-check also returns ($180m − $75m − $5m) / $80m = 1.25. The near-cash screen is only ($18m + $12m) / $80m = 0.38.
流动资产为 1,800 +1,200 +7,000 +7,500 +500 =1.80 亿美元。流动负债为 8,000 万，包括应付 3,400 万、应计负债 1,800 万、流动债务 1,600 万和合同负债 1,200 万。流动比率 =1.80 亿 /8,000 万 =2.25；本页速动比率 =（1,800 +1,200 +7,000）/8,000 =1.25。扣除法交叉核对同样得到（1.80 亿 −7,500 −500）/8,000 =1.25；更窄的近现金筛查仅为（1,800 +1,200）/8,000 =0.38。

IAS 7 defines cash and cash equivalents for cash-flow presentation, while IFRS 9 addresses recognition, classification, measurement, and expected credit losses for financial instruments. Those standards do not declare an analyst’s quick numerator. The formula remains a disclosed analytical convention, and the filing determines what the underlying balances actually are. IFRS 7 disclosures about financial-instrument significance and risk help test exposure, but cannot replace contract and market evidence.
IAS 7 为现金流列报定义现金及现金等价物，IFRS 9 处理金融工具的确认、分类、计量和预期信用损失；这些准则并不会替分析者规定速动分子。公式仍是一项需披露的分析约定，底层余额是什么要由财报决定。IFRS 7 对金融工具重要性与风险的披露有助于检验敞口，但不能取代合同和市场证据。
The denominator deserves equal scrutiny. AeroLatch’s $12m contract liability reflects advance consideration for parts or service, not necessarily a $12m cash call, but the company still owes performance or may face refund terms. Removing it would cease to be the reported quick ratio. Likewise, debt expected to be refinanced stays in the reported denominator when presented current; any alternative must identify the contractual and framework basis.
分母值得同等审查。AeroLatch 的 1,200 万美元合同负债代表零件或服务预收，并不必然形成 1,200 万现金索取，但公司仍欠履约，也可能面对退款条款。将其剔除就不再是报告口径速动比率。同样，若财报把预计再融资债务列为流动，就应留在报告分母；任何替代处理都要说明合同与框架依据。
Pressure-test the collection ring one assumption at a time每次改变一个假设，对收款圈施压
Of the $70m net receivables, $12m is over 90 days past due and $28m in total is due from one airline group. The figures are fictional and already net of the reported allowance. Sensitivity haircuts below are additional assumptions; they are not GAAP or IFRS measurements, audit adjustments, expected outcomes, or accusations that the allowance is inadequate.
额外分析，不是修订账目7,000 万美元应收净额中，1,200 万已逾期超过九十天，合计 2,800 万来自同一航空集团。数字均为虚构，且已经扣除报告备抵。以下敏感度折扣是额外假设，不是 GAAP 或 IFRS 计量、审计调整、预期结果，也不指控报告备抵不足。
| Numerator sensitivity | Cash | Securities | Receivables | Quick numerator | Ratio |
|---|---|---|---|---|---|
| Reported convention | $18m | $12m | $70m | $100m | 1.25 |
| Exclude $3m restricted cash | $15m | $12m | $70m | $97m | 1.21 |
| Also recover only 50% of $12m overdue balance | $15m | $12m | $64m | $91m | 1.14 |
| Concentration stress: recover 50% of $28m customer balance; value $4m thin security at 70% | $15m | $10.8m | $56m | $81.8m | 1.02 |
| 分子敏感度 | 现金 | 证券 | 应收 | 速动分子 | 比率 |
|---|---|---|---|---|---|
| 报告约定 | 1,800 万 | 1,200 万 | 7,000 万 | 1.00 亿美元 | 1.25 |
| 排除 300 万受限现金 | 1,500 万 | 1,200 万 | 7,000 万 | 9,700 万美元 | 1.21 |
| 再假设 1,200 万逾期款只收回 50% | 1,500 万 | 1,200 万 | 6,400 万 | 9,100 万美元 | 1.14 |
| 集中压力：2,800 万客户余额收回 50%；400 万薄弱证券按 70% 计 | 1,500 万 | 1,080 万 | 5,600 万 | 8,180 万美元 | 1.02 |
Each row keeps the $80m reported denominator. The last row uses $8m other securities + 70% × $4m = $10.8m, and $70m − 50% × $28m = $56m receivables. It does not add the overdue haircut again because the $12m overdue amount sits inside the $28m concentrated balance; double counting would understate the numerator. The ratio’s apparent cushion falls sharply without changing inventory, showing that concentration can matter more than the headline exclusion.
每行都保留 8,000 万美元报告分母。最后一行证券为其他 800 万 +70% ×400 万 =1,080 万，应收为 7,000 万 −50% ×2,800 万 =5,600 万。由于 1,200 万逾期额已经包含在 2,800 万集中余额中，不能再次叠加逾期折扣，否则会重复减少分子。即使存货不变，比率缓冲也明显下降，说明集中风险可能比“剔除存货”这个标题更重要。
Do not confuse exclusion with worthlessness不要把剔除误解为毫无价值
| Inventory outside the quick numerator | Carrying amount | Fictional operating evidence |
|---|---|---|
| Standard consumables | $20m | Broad customer use; shelf-life and obsolescence still matter |
| Repairable rotable components | $35m | $26m assigned to signed overhaul work orders |
| Specialized repair kits | $20m | Narrow aircraft compatibility and customer approval requirements |
| Total inventory | $75m | All excluded from adopted quick numerator |
| 速动分子外的存货 | 账面金额 | 虚构经营证据 |
|---|---|---|
| 标准耗材 | 2,000 万美元 | 客户用途较广，但保质期与淘汰仍重要 |
| 可修复周转部件 | 3,500 万美元 | 其中 2,600 万已分配给已签大修工单 |
| 专用维修套件 | 2,000 万美元 | 机型兼容范围窄，且需要客户批准 |
| 存货合计 | 7,500 万美元 | 全部排除在本页速动分子之外 |
The quick ratio assigns zero numerator credit to all $75m, while the current ratio gives the entire carrying amount equal arithmetic weight. Neither treatment is an inventory valuation. IAS 2 uses the lower of cost and net realizable value, yet realization timing, inspection, certification, transferability, cancellation, and cash-to-complete still matter. Signed orders support a demand pathway for $26m of rotables, or 74.3% of that category, but do not guarantee acceptance, margin, payment, or absence of cancellation.
速动比率不给 7,500 万存货任何分子权重，流动比率却让全部账面金额获得相同算术权重；两种处理都不是存货估值。IAS 2 使用成本与可变现净值孰低，但变现时点、检验、认证、可转移性、取消权与完工现金仍然重要。已签订单为 2,600 万周转部件提供需求路径，占该类 74.3%，却不保证验收、利润、付款或不会取消。
Prepayments are excluded for a different reason: they usually represent a right to future goods or services rather than a claim to receive cash on demand. A refundable deposit may deserve separate analysis, but silently adding it to the adopted numerator changes the definition. Name the contract and refund condition before assigning liquidity value.
预付款被剔除的理由不同：它通常代表未来取得商品或服务的权利，而不是随时收取现金的权利。可退保证金可以另行分析，但悄悄加入本页分子会改变定义。赋予流动性价值前，必须写明合同及退款条件。

The fictional balance sheet reports $100m chosen quick assets and $80m current liabilities.
报告事实虚构资产负债表报告本页选定速动资产 1.00 亿、流动负债 8,000 万美元。
Quick ratio is 1.25, current ratio 2.25, and near-cash screen 0.38.
计算速动比率 1.25，流动比率 2.25，近现金筛查 0.38。
Restriction, collection recoveries, and the thin-security value in sensitivities are invented.

Actual collection, market depth, order cancellation, liability timing, and funding access remain unresolved.
判断与缺口实际回款、市场深度、订单取消、负债时点与融资渠道仍未解决。
A defensible conclusion reads: “AeroLatch’s chosen reported quick ratio is 1.25 versus a 2.25 current ratio. The difference is $75m inventory and $5m prepayments, not proof those assets lack economic value. After explicitly assumed restrictions, overdue recovery, customer concentration, and security liquidity, quick coverage ranges from 1.21 to 1.02. The range is diagnostic, not a revised filing. Confidence depends on subsequent customer collections, security sale evidence, debt and deposit terms, and whether signed maintenance orders convert specialized inventory without margin loss.”
可辩护结论可以写成：“AeroLatch 按本页口径的报告速动比率为 1.25，而流动比率为 2.25；差额来自 7,500 万存货和 500 万预付款，并不证明这些资产没有经济价值。加入明确假设的现金限制、逾期回收、客户集中与证券流动性后，速动覆盖从 1.21 降至 1.02。该区间用于诊断，不是修订财报。可信度取决于期后客户回款、证券出售证据、债务与预收条款，以及已签维修订单能否让专用库存不损失利润地转化。”

Not universally. This page adopts cash plus short-term marketable securities plus receivables. The subtraction form matches AeroLatch only because its remaining current-asset lines are exactly those three. List components rather than relying on the label.
速动比率总是流动资产减存货与预付款吗？并非普遍如此。本页采用现金加短期可交易证券加应收。扣除法在 AeroLatch 得到相同结果，只因剩余流动资产恰好就是这三项。应列出组成，而不能只依赖名称。
Keep the reported convention visible, then examine whether the cash can meet the same liabilities. AeroLatch’s 1.25 includes reported cash; its 1.21 sensitivity excludes $3m restricted cash. The second number is an analytical scenario, not a reclassification.
受限现金应纳入吗？应保留报告约定，再判断现金能否覆盖同一组负债。AeroLatch 的 1.25 纳入报告现金，1.21 敏感度排除 300 万受限现金；后者是分析情景，不是重分类。
No. Check quoted markets, trading volume, spreads, settlement, pledges, maturity, and price risk. The fictional 70% value for one $4m position is a stress assumption, not a claim that all marketable securities need that haircut.
所有短期证券都能按账面价值快速变现吗？不能这样假设。应检查报价市场、成交量、价差、结算、质押、到期与价格风险。虚构案例对 400 万头寸采用 70% 只是一项压力假设，不表示所有可交易证券都需该折扣。
No. It supports a demand pathway but inventory still needs inspection, certification, delivery, customer acceptance, and collection. Cancellation, margin, compatibility, and cash-to-complete remain relevant. Keep it outside the adopted numerator and analyze it separately.
已签工单会让存货变成速动资产吗？不会。工单支持需求路径，但库存仍需检验、认证、交付、客户验收与收款；取消、利润、兼容性和完工现金仍重要。应把存货留在本页分子外并单独分析。
Not from the reported quick ratio. They are current obligations even when settlement is performance rather than cash. Study refund clauses and fulfillment cost separately; removing them creates a different denominator that must be named and justified.
合同负债不是债务，能否从分母删除？不能从报告速动比率直接删除。即使通过履约而非现金结算，它们仍是流动义务。退款条款与履约成本应另行研究；删除后会形成另一分母，必须命名并说明理由。
