1. 036How does operating leverage affect debt versus equity holders?Credit analysis and ratingsHardsuperdayOaktree Capital ManagementCredit · Los Angeles · 2024

   Say this

   Operating leverage amplifies the volatility of EBIT, and because equity is the residual claim, equity holders get the amplified upside and downside while debt holders get amplified downside with no upside. So high operating leverage is straightforwardly bad for a lender and a mixed blessing for a shareholder.

   Then walk it

   1. Mechanism: a high fixed-cost base means a small revenue change produces a large EBIT change. A business with 70 percent fixed costs loses about 2.3 times as much EBIT percentage-wise as its revenue decline.
   2. Take an airline, a steel mill or a semiconductor fab. Revenue down 20 percent can take EBIT down 60 or 70 percent and straight through interest coverage. Same 20 percent decline at a staffing agency, where costs are variable, barely moves EBIT.
   3. For the lender, that translates into a much fatter left tail on coverage and leverage. So you lend less, at a higher spread, with tighter covenants, and you underwrite to a trough EBITDA rather than a mid-cycle one.
   4. For the equity holder it cuts both ways, and in a recovery it is spectacular: the same amplification means EBIT triples off a trough. That is why cyclical equities rally hardest early in a cycle.
   5. The critical interaction is with financial leverage. Operating leverage and financial leverage multiply. A high fixed-cost business at 5 turns of debt is a fundamentally different credit from a subscription business at 5 turns, which is exactly why software gets levered higher than shipbuilding at the same rating.
   6. So the practical rule for a credit investor: set your maximum leverage inversely to operating leverage. And the number to watch is not leverage at all but EBITDA volatility through the last two downturns.

   Where candidates lose it

   Explaining operating leverage correctly and never connecting it to the lending decision. The point the interviewer is testing is that operating and financial leverage compound, so the maximum debt a business can carry depends on its cost structure. Say that out loud.

   • So how much debt would you lend to an airline versus a software company?
   • How do you estimate trough EBITDA?
   • Does high operating leverage ever help a lender?
