8.3 Key Financial Ratios for Directors

Key Takeaways

  • Liquidity ratios (current, quick) test near-term bill-paying capacity; leverage ratios (D/E, interest coverage) test debt burden and serviceability
  • Profitability ratios (gross margin, EBITDA margin, ROE, ROCE) show whether the business earns adequate returns on sales and capital
  • Efficiency ratios (receivable, inventory, payable days and cash conversion cycle) reveal working-capital health and cash trapped in operations
  • Ratios are diagnostic tools—teaching ranges are not universal rules; industry, business model, and seasonality matter
  • Exam-style pattern recognition: high leverage plus falling interest coverage is a classic financial distress signal for board intervention

8.3 Key Financial Ratios for Directors

Quick Answer: Financial ratios compress balance sheet, P&L, and cash-flow relationships into board-usable diagnostics: liquidity (can we pay near-term obligations?), leverage (how much debt risk?), profitability (are we earning enough?), and efficiency (how fast do we convert operations to cash?). Independent directors use ratios to ask better questions—not to replace full financial statement reading.

Ratios appear throughout board packs, credit rating discussions, covenant packages, and the IICA proficiency test’s accountancy domain. Master a small toolkit deeply rather than memorising dozens of obscure formulas.

How Directors Should Use Ratios

  1. Trend first — three to five years beats one year.
  2. Peer second — compare within industry and business model.
  3. Narrative third — every ratio movement needs a business story.
  4. Combination always — one “good” ratio can hide another problem (high current ratio driven by unsellable inventory).
  5. Teaching ranges are guides, not laws — a software firm and a steel plant will not share the same ideal inventory days.

Liquidity Ratios

Current ratio

Formula: Current ratio = Current assets ÷ Current liabilities

Meaning: Coverage of short-term obligations by short-term resources.

Teaching range (general corporates)Interpretation sketch
Below ~1.0Current liabilities exceed current assets — liquidity stress risk
~1.2 to 2.0Often acceptable for many industrial models if quality of CA is good
Far above ~3.0May mean idle cash/inventory or conservative under-investment—investigate

Caveats: Inventory-heavy current assets can overstate liquidity. Related-party receivables may not be collectible on demand. Use alongside the quick ratio and cash flow statement.

Quick ratio (acid test)

Formula: Quick ratio = (Current assets − Inventories) ÷ Current liabilities

Sometimes cash + receivables + other quick assets are used explicitly in the numerator.

Meaning: Ability to meet current liabilities without relying on selling inventory.

Teaching rangeInterpretation sketch
Below ~0.8–1.0Dependence on inventory liquidation or refinancing for near-term bills
Around 1.0+Stronger short-term buffer for many models

ID question: “Our current ratio is 1.8 but quick ratio is 0.6—what inventory is slow-moving, and what is the cash collection plan for the next 90 days?”

Leverage Ratios

Debt-to-equity (D/E)

Formula: D/E = Total debt ÷ Equity

Define debt consistently (usually interest-bearing borrowings; some analyses include lease liabilities under Ind AS 116). Equity is shareholders’ equity (watch for negative equity or revaluation-heavy equity).

Teaching rangeInterpretation sketch
Low (e.g., <0.5)Conservative capital structure—or under-levered if ROCE > after-tax cost of debt
Moderate (e.g., 0.5–1.5)Common band for many industrials—context needed
High (e.g., >2)Elevated financial risk; covenants and interest coverage become critical

Interest coverage

Formula: Interest coverage = EBIT ÷ Finance costs (or EBITDA ÷ interest, if that is the covenant definition—know which)

Meaning: How many times operating profit covers interest.

Teaching rangeInterpretation sketch
Below ~1.5–2.0Distress zone—profit barely covers interest
~3 to 6Often comfortable for stable businesses
Very highLow debt drag—or temporarily depressed interest

Exam-style distress pattern

High leverage + falling interest coverage = classic distress signal.

Example: D/E rises from 0.8 to 2.2 while interest coverage falls from 5.0× to 1.3×. Even if PAT is still slightly positive, the board should demand a deleveraging plan, capex freeze options, working-capital recovery, and covenant headroom analysis—not congratulations on “still profitable.”

Profitability Ratios

Gross margin

Formula: Gross margin % = (Revenue − Cost of goods sold / direct costs) ÷ Revenue × 100

Shows pricing power and direct cost control. Falling gross margin with rising revenue can mean discounting wars or input-cost pressure not passed through.

EBITDA margin

Formula: EBITDA margin % = EBITDA ÷ Revenue × 100

Useful for operating comparison; still ignores capex and interest. Teaching intuition: stable or expanding EBITDA margins with honest revenue recognition support earnings quality narratives.

Return on equity (ROE)

Formula: ROE = PAT ÷ Average equity (or closing equity in simplified teaching)

Meaning: Accounting return to shareholders. High ROE can come from genuine performance or from thin equity and high leverage (which raises risk). Always read ROE with D/E.

Teaching sketchNote
ROE well above cost of equity expectationsAttractive if sustainable and not leverage-manufactured
ROE falling with stable marginsAsset bloat, equity build, or profit decline
ROE high + D/E very highFragile—shock to EBIT can wipe equity returns

Return on capital employed (ROCE)

Formula (common teaching form): ROCE = EBIT ÷ Capital employed

where Capital employed ≈ Equity + Interest-bearing debt − Non-core investments/cash adjustments (definitions vary; use the company’s stated definition consistently).

Meaning: Return on the total long-term capital package—often better than ROE for comparing operating performance across different leverage choices.

Teaching sketchNote
ROCE > after-tax cost of capital (conceptually)Value-creative direction
ROCE declining while capex risesProjects not yet earning—or value-destructive investment
ROCE << interest rate on new debtBorrowing to fund low-return assets destroys value

Efficiency Ratios and Cash Conversion Cycle

Receivable days (DSO)

Formula: Receivable days ≈ (Trade receivables ÷ Credit sales) × 365

(Use revenue if credit sales not broken out—be consistent.)

Rising days: slower collections, weaker customers, or aggressive revenue booking.

Inventory days

Formula: Inventory days ≈ (Inventory ÷ Cost of goods sold) × 365

Rising days: slow sales, overproduction, obsolescence risk, or deliberate stocking.

Payable days

Formula: Payable days ≈ (Trade payables ÷ Purchases or COGS) × 365

Rising days: negotiating power or inability to pay on time. Extreme stretch is a stress signal, not a free lunch.

Cash conversion cycle (CCC)

Formula: CCC = Receivable days + Inventory days − Payable days

Meaning: Net days the business ties up cash in the operating cycle.

CCC movementDirector reading
CCC shorteningOperations freeing cash—positive if not from starving critical suppliers unfairly
CCC lengtheningCash trapped—fund with debt/equity or cut growth
Negative CCCCustomers/suppliers fund the business (common in some retail models)

Worked micro example

Receivable days 70, inventory days 80, payable days 45 → CCC = 70+80−45 = 105 days.

If next year receivables move to 95 days and inventory to 100 with payables at 50 → CCC = 145 days. That 40-day worsening on a large cost base can absorb enormous cash even if PAT rises.

Interpretation Scenarios (Exam Style)

Scenario A — Liquidity illusion

Current ratio 2.5, but 70% of current assets are slow inventory and disputed related-party receivables. Reading: Liquidity is weaker than the headline ratio; demand ageing and NRV tests.

Scenario B — Leverage distress

D/E 2.5, interest coverage 1.2×, operating cash flow negative. Reading: High leverage + weak coverage + cash burn—distress pathway; escalate to audit committee and full board contingency planning.

Scenario C — Efficiency success

PAT flat, but CCC improves from 90 to 55 days and debt falls. Reading: Working-capital discipline created cash—often better governance news than a one-off PAT spike.

Scenario D — Profitability without return

EBITDA margin expands, yet ROCE falls because capital employed ballooned with low-return acquisitions. Reading: Challenge capital allocation, not only margin slides.

Common Exam Traps

  • Treating any single “ideal” ratio as universal law across industries
  • Using inconsistent debt definitions when comparing D/E year to year
  • Celebrating high ROE without checking leverage
  • Ignoring that quick ratio removes inventory for a reason
  • Computing receivable days on the wrong sales base and over-interpreting noise
  • Looking at coverage on EBITDA when covenants use a different definition—without noticing

Exam Focus Checklist

  • Write formulas for current, quick, D/E, interest coverage, gross/EBITDA margins, ROE, ROCE
  • Compute receivable, inventory, payable days and CCC
  • Interpret high leverage + falling coverage as distress
  • State that teaching ranges are guides, not universal rules
  • Combine ratios with notes quality (ageing, contingencies, related parties)
  • Translate ratio movements into board questions
