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
- Trend first — three to five years beats one year.
- Peer second — compare within industry and business model.
- Narrative third — every ratio movement needs a business story.
- Combination always — one “good” ratio can hide another problem (high current ratio driven by unsellable inventory).
- 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 ~1.0 | Current liabilities exceed current assets — liquidity stress risk |
| ~1.2 to 2.0 | Often acceptable for many industrial models if quality of CA is good |
| Far above ~3.0 | May 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 range | Interpretation sketch |
|---|---|
| Below ~0.8–1.0 | Dependence 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 range | Interpretation 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 range | Interpretation sketch |
|---|---|
| Below ~1.5–2.0 | Distress zone—profit barely covers interest |
| ~3 to 6 | Often comfortable for stable businesses |
| Very high | Low 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 sketch | Note |
|---|---|
| ROE well above cost of equity expectations | Attractive if sustainable and not leverage-manufactured |
| ROE falling with stable margins | Asset bloat, equity build, or profit decline |
| ROE high + D/E very high | Fragile—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 sketch | Note |
|---|---|
| ROCE > after-tax cost of capital (conceptually) | Value-creative direction |
| ROCE declining while capex rises | Projects not yet earning—or value-destructive investment |
| ROCE << interest rate on new debt | Borrowing 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 movement | Director reading |
|---|---|
| CCC shortening | Operations freeing cash—positive if not from starving critical suppliers unfairly |
| CCC lengthening | Cash trapped—fund with debt/equity or cut growth |
| Negative CCC | Customers/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.
Ratio Dashboard for Board Packs
| Category | Ratio | Formula (teaching) | What “good” often looks like (guide only) |
|---|---|---|---|
| Liquidity | Current | CA ÷ CL | ~1.2–2.0 for many industrials if CA quality is high |
| Liquidity | Quick | (CA − Inv) ÷ CL | ~1.0+ preferred when inventory is slow |
| Leverage | D/E | Debt ÷ Equity | Context-heavy; rising toward >2 needs challenge |
| Leverage | Interest cover | EBIT ÷ Interest | Comfort often ≥3×; <2× is warning territory |
| Profitability | Gross margin | Gross profit ÷ Revenue | Stable/up with peers |
| Profitability | EBITDA margin | EBITDA ÷ Revenue | Stable/up; reconcile to cash |
| Profitability | ROE | PAT ÷ Equity | Healthy but not leverage-illusory |
| Profitability | ROCE | EBIT ÷ Capital employed | Above cost of capital directionally |
| Efficiency | Rec. days | Rec. ÷ Sales × 365 | Flat/down vs credit policy |
| Efficiency | Inv. days | Inv. ÷ COGS × 365 | Flat/down unless strategic build |
| Efficiency | Pay. days | Pay. ÷ Purchases × 365 | Stable; extreme rise = stress check |
| Efficiency | CCC | DSO + DIO − DPO | Stable/shortening without supplier abuse |
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
