1. 004Do a paper LBO. EBITDA of $100, bought at 10 times, five turns of leverage, exit at the same multiple in five years with EBITDA at $150.LBO mechanicsHardtechnicalBain CapitalGeneralist · Boston · 2024WPWarburg PincusPrivate Equity · New York · 2014Clayton Dubilier and RicePrivate Equity · London · 2026

   Say this

   Entry equity is $500. With about $250 of debt repaid over five years, exit equity is $1,500 less $250, so $1,250. That is 2.5 times the money and roughly a 20 percent IRR.

   Then walk it

   1. Entry: $100 EBITDA at 10 times is $1,000 enterprise value. Debt at five turns is $500, so the sponsor writes $500.
   2. Cash generation: EBITDA ramps from $100 to $150, averaging about $125. Interest on $500 at 8 percent is roughly $40. Less CapEx of $25, working capital of $5, and cash taxes on EBIT.
   3. That leaves around $50 a year to sweep, so about $250 of debt repaid. Ending debt is $250.
   4. Exit: $150 at 10 times is $1,500, less $250 of debt, equals $1,250 of equity.
   5. Return: $1,250 on $500 is 2.5 times. Using the standard grid, 2.0 times over five years is about 15 percent, 2.5 times is about 20 percent, 3.0 times is about 25 percent.
   6. Attribution: EBITDA grew 50 percent and debt halved, with no multiple expansion assumed. That is the version an investment committee likes, because the return does not depend on the exit market.

   Where candidates lose it

   Reaching for a calculator or chasing decimal precision. Round hard, state every assumption out loud, and know the IRR grid cold. Also announce your interest rate and CapEx assumptions rather than letting them appear silently.

   Expect next

   • What if you exit at 8 times?
   • What return does the fund actually need?
   • How much of that return came from each driver?

2. 059How would you evaluate whether to lend to a construction company?Credit and financingHardsuperdayBain CapitalCredit · New York · 2024

   Say this

   Construction is one of the hardest credits there is: cyclical, low margin, with percentage-of-completion accounting that can hide problems and working capital that swings violently. I would underwrite the backlog quality and the contract structure before anything else.

   Then walk it

   1. Backlog is the revenue, so its quality is the credit. How much is contracted versus awarded, what is the execution timeline, and what is the cancellation risk?
   2. Contract structure is the single biggest determinant. Fixed-price contracts put inflation and overrun risk on the contractor; cost-plus contracts pass it to the customer. A book of fixed-price work signed before an inflation spike is where construction companies die.
   3. The accounting risk: percentage-of-completion recognises profit based on management's estimate of costs to complete. Optimistic estimates inflate current profit and reverse later. So I would test historical estimate accuracy, comparing forecast margin at each stage to the final outcome by project.
   4. Working capital is brutal: retentions held by customers, unbilled work in progress, and payables to subcontractors. Cash and profit diverge persistently, so I would underwrite cash conversion over several years rather than EBITDA.
   5. Then counterparty and concentration: who are the customers, are they creditworthy, and what happens if one large project is disputed? Construction disputes are slow and expensive.
   6. Given all of that, I would lend conservatively, at low leverage, with tight maintenance covenants and security over receivables, and I would want the historical record through a full cycle. If the business is mostly fixed-price with thin margins, I would probably pass.

   Where candidates lose it

   Applying a generic credit framework. The sector-specific risks are percentage-of-completion estimate manipulation and fixed-price contract exposure. Naming both, and saying how you would test estimate accuracy, is the answer.

   Expect next

   • How would you test their cost-to-complete estimates?
   • What covenants would you want?
   • What leverage would you actually lend at?
