Corporate Failure: formula sheet

Full chapter guide

Key formulas

Classification of causes
Causes of failure = Internal (controllable) + External (environmental)
Always split your answer under these two heads, with a few points under each.
Stages of decline
Latent weakness → Financial distress → Crisis/Insolvency
Name the stage when you describe a warning sign. Early stages are the best time to turn around.
Economic failure test
Return on capital employed < Cost of capital over a sustained period
A company can be economically failing while still solvent. Say 'sustained', not one bad year.
Liquidity warning ratio
Current ratio = Current assets ÷ Current liabilities
A falling trend is a warning sign. Do not state a fixed 'safe' value as a rule; it varies by industry.
Technical insolvency test
Technical insolvency: cash and liquid resources < debts currently due, while Total assets > Total liabilities
A cash-flow (flow) problem. Net worth is still positive.
Legal insolvency test
Legal insolvency: Total liabilities > Fair value of total assets, so Net worth = Assets − Liabilities < 0
A balance sheet (stock) problem. Use fair or realisable values, not only book values.
Net worth
Net worth = Total assets − Total liabilities
Positive in technical insolvency, negative in legal insolvency.
Current ratio
Current ratio = Current assets ÷ Current liabilities
A low ratio is a warning sign of distress. It is a signal, not proof of insolvency.
Interest coverage ratio
Interest coverage = EBIT ÷ Interest expense
A ratio below 1 means operating profit does not cover interest, a common distress signal.
Original Z-score (public manufacturing firms)
Z = 1.2 X1 + 1.4 X2 + 3.3 X3 + 0.6 X4 + 1.0 X5
Use for listed manufacturing companies. Some books write the weights as decimals (0.012, 0.014, 0.033, 0.006, 0.999) with ratios in percentages; use the form the question gives.
Variables X1 to X5
X1 = Working capital ÷ Total assets; X2 = Retained earnings ÷ Total assets; X3 = EBIT ÷ Total assets; X4 = Market value of equity ÷ Total liabilities; X5 = Sales ÷ Total assets
Working capital = current assets − current liabilities. Total liabilities means book value of all debt and liabilities.
Zones for original model
Z > 2.99: safe; 1.81 ≤ Z ≤ 2.99: grey; Z < 1.81: distress
Some texts use 1.8 and 3.0 as rounded cut-offs. Use what the question states.
Z′-score (private manufacturing firms)
Z′ = 0.717 X1 + 0.847 X2 + 3.107 X3 + 0.420 X4 + 0.998 X5
X4 uses book value of equity ÷ total liabilities. Zones: Z′ > 2.9 safe; 1.23 to 2.9 grey; Z′ < 1.23 distress.
Z″-score (non-manufacturing and emerging markets)
Z″ = 6.56 X1 + 3.26 X2 + 6.72 X3 + 1.05 X4
No sales ratio, so it removes industry effects of asset turnover. X4 uses book value of equity. Zones: Z″ > 2.6 safe; 1.1 to 2.6 grey; Z″ < 1.1 distress.
Springate model
S = 1.03A + 3.07B + 0.66C + 0.4D
A = working capital ÷ total assets; B = EBIT ÷ total assets; C = profit before tax ÷ current liabilities; D = sales ÷ total assets. A score below 0.862 classifies the firm as likely to fail. Confirm the weights given in the question, and use those.
Beaver's best single ratio
Cash flow to total debt = (net income + depreciation) ÷ total debt
Lower values signal higher failure risk. Beaver tested one ratio at a time.
Altman Z-score (original, listed manufacturers)
Z = 1.2X1 + 1.4X2 + 3.3X3 + 0.6X4 + 1.0X5
Zones: above 2.99 safe, 1.81 to 2.99 grey, below 1.81 distress. Use only if the question supplies or asks for it.
Argenti A-score logic
Defects + Mistakes + Symptoms = A-score
Qualitative marks are assigned to each part. A higher total means higher risk. Use the cut-offs given in the question or in your study material.
Common warning ratios
Current ratio = current assets ÷ current liabilities; Interest cover = EBIT ÷ interest; Gearing = debt ÷ (debt + equity)
Judge by direction over several years, not one figure.
Continue-or-exit rule
Continue if going-concern value (PV of future cash flows) > liquidation value (net realisable value of assets less liabilities costs)
Use present values. Include costs of closure, such as employee dues and legal costs, in the exit value.
Debt-equity ratio
Debt-equity ratio = Total debt ÷ Shareholders' equity
A high ratio points to financial restructuring as the likely remedy.
Interest coverage ratio
Interest coverage = EBIT ÷ Interest expense
A ratio below 1 means operating profit cannot pay interest. Debt relief becomes urgent.
Current ratio
Current ratio = Current assets ÷ Current liabilities
Used to judge short-term liquidity stress during the stabilisation stage.
Turnaround sequence
Diagnose → Stabilise → Restructure → Revive and grow
Learn this order. Exam answers are usually marked against these stages.

Quick revision

  • Corporate failure means inability to pay debts or earn adequate returns, putting survival at risk.
  • Causes split into internal (management, finance, operations) and external (economy, market, policy).
  • Financial distress comes before insolvency; a firm can be distressed without being legally insolvent.
  • Insolvency means inability to pay debts as they fall due, or liabilities exceeding assets.
  • Altman Z-Score combines several financial ratios into one number to signal bankruptcy risk.
  • Compute each Z-Score ratio separately before applying its weight, then add.
  • Compare the score with the zone cut-offs from your study material, and state the zone in words.
  • A low score is a warning, not proof of failure; add trend and context to your comment.
  • Ratio analysis for failure looks at liquidity, leverage, profitability and interest cover.
  • Falling current ratio with rising debt and falling margins is a classic warning pattern.
  • Turnaround strategies include cost cutting, asset sale, debt restructuring and change in management.
  • Match the remedy to the cause: a demand problem needs strategic change, not only cost cuts.

Common mistakes

  • Writing a generic list of causes without using facts from the case. Fix: Quote the facts given, such as rising debt or falling sales, and label each one as a cause.
  • Treating corporate failure as only liquidation. Fix: State both legal and economic meanings, and explain that decline is a process.
  • Treating financial distress and bankruptcy as the same thing. Fix: Distress is an economic condition and may be reversed. Bankruptcy is a legal process or status. A firm can be distressed for years without any legal proceeding.
  • Calling a firm legally insolvent because it missed a payment. Fix: A missed payment with assets above liabilities is technical insolvency. Legal insolvency needs liabilities greater than assets.
  • Dividing market value of equity by total assets for X4. Fix: Remember X4 is equity value ÷ total liabilities. Underline 'liabilities' when you list the formula.
  • Using the wrong version for a private or service company. Fix: Read the firm description first. Private manufacturer: Z′ with book equity. Service or non-manufacturing: Z″ without sales.
  • Mixing up univariate and multivariate models. Fix: Remember: Beaver takes one ratio at a time. Altman, Springate and Taffler combine ratios into a score.
  • Calling Argenti's A-score a ratio model. Fix: Argenti is qualitative. It scores management defects, mistakes and symptoms.
  • Listing every strategy without linking it to the case. Fix: Begin with the cause and choose only the remedies that fit it. Use facts from the case.
  • Jumping to growth strategies before stabilising cash. Fix: Follow the sequence: diagnose, stabilise, restructure, then grow. A firm out of cash cannot invest.

Exam tips

  • In case questions, tag every fact as internal or external before writing; it keeps your answer structured and scores marks for application.
  • Use the three stages as headings in your own notes so you can place any scenario quickly.
  • Always mention both financial and non-financial warning signs, such as management exits and auditor resignation.
  • In MCQs, check whether the item is a cause, a symptom or a stage; options often mix them.
  • End descriptive answers with a recommendation suited to the stage reached.
  • In MCQs, look for the keyword: 'unable to pay debts when due' points to technical insolvency, and 'liabilities exceed assets' points to legal insolvency.
  • In descriptive answers, define each term in one line, then add a comparison on liquidity versus net worth. This earns easy marks.
  • In case scenarios, quote figures such as net worth and coverage ratio to support your classification.
