Case 100Credit analysis and ratingsCore
Two borrowers each have revenue of Rs 1,000 crore, EBITDA of Rs 150 crore and debt of Rs 450 crore. One has half its costs fixed, the other a tenth. Revenue falls 20%. What happens to each, and what does operating leverage mean for the lender versus the shareholder?
1The situation
Durvesh Chemicals and Brisvara Staffing look identical on paper: revenue of Rs 1,000 crore, EBITDA of Rs 150 crore, and Rs 450 crore of debt at 9%, so leverage is 3.0x and EBITDA covers interest 3.7 times.
Their costs are built differently. Durvesh runs plants: half of its Rs 850 crore of costs, Rs 425.0 crore, are fixed, and the rest move with volume. Brisvara places contract workers and pays them only when a client does: only a tenth of its costs, Rs 85.0 crore, are fixed. In a downturn, both see revenue fall 20%.

What happens to EBITDA, leverage and interest cover for each, and how does operating leverage affect lenders and shareholders differently?
Quick check
After a 20% revenue fall, roughly what is Durvesh's EBITDA?

Try it on paper, then open one step at a time.
30-second answerThe answer to give first
Durvesh's EBITDA falls to Rs 35 crore and leverage jumps to 12.9x; Brisvara's falls to Rs 103 crore and leverage only to 4.4x. Fixed costs turn a 20% revenue dip into a 77% EBITDA fall, and Durvesh can no longer cover its interest. Operating leverage amplifies both directions, but the shareholder keeps the upside while the lender, paid a fixed coupon, only feels the downside. Lenders therefore want less debt on high fixed-cost businesses.
Step 1Why do two identical-looking borrowers react so differently?
Because EBITDA is what is left after costs, and only variable costs fall when revenue falls. Durvesh loses Rs 200 crore of revenue but saves only Rs 85 crore of cost, so EBITDA falls Rs 115 crore; Brisvara saves Rs 153 crore and EBITDA falls only Rs 47 crore. A restaurant owner who owns the kitchen and pays fixed salaries keeps paying them on a quiet night; a caterer who hires staff per event simply hires fewer.

| Rs crore | Durvesh, before | Durvesh, after | Brisvara, before | Brisvara, after |
|---|---|---|---|---|
| Revenue | 1,000 | 800 | 1,000 | 800 |
| Variable costs | (425) | (340) | (765) | (612) |
| Fixed costs | (425) | (425) | (85) | (85) |
| EBITDA | 150 | 35 | 150 | 103 |
| Debt / EBITDA | 3.0x | 12.9x | 3.0x | 4.4x |
| EBITDA / interest of 40.5 | 3.7x | 0.86x | 3.7x | 2.54x |
Step 2Why does operating leverage hurt the lender more than the shareholder?
Run the upturn too. With revenue up 20%, Durvesh's EBITDA rises 77% to Rs 265 crore and Brisvara's 31%. The shareholder owns that upside in full; the lender still receives its 9% and nothing more, while standing directly in front of the downside. So operating leverage is a gamble a shareholder might welcome and a lender cannot be paid for. At Rs 35 crore of EBITDA, Durvesh covers its Rs 40.5 crore of interest only 0.86 times: the lender's claim is at risk after one bad year.
Close with what a lender does about it. Lend less against high fixed-cost businesses, and size the loan on EBITDA after a stress, not on today's figure. If a lender wants Durvesh to stay under 4.5x in a 20% revenue fall, debt can be no more than about Rs 157 crore, 1.05x today's EBITDA; Brisvara could carry its Rs 450 crore comfortably. The limitation: fixed costs are rarely perfectly fixed, and a management team will cut some of them in a downturn, but not quickly enough to save a loan sized on good-year EBITDA.
Where candidates lose it
The common error is cutting EBITDA by the same 20% as revenue, to Rs 120 crore, for both companies. That assumes every cost is variable and hides the whole point of the question.
The second is answering that operating leverage is bad for everyone. It amplifies both ways; the asymmetry comes from the lender's capped payoff, and saying that is what the interviewer is listening for.
