Cash-Free Debt-Free Explained: What It Means in M&A and PE Interviews
Cash-free debt-free (CFDF) mechanics for IB and PE: enterprise vs equity value, excess cash, debt-like items, WC pegs, locked box contrast, and true-up traps.
PE · 4 min read
Students Google "cash free debt free" constantly because CIMs and SPAs throw the phrase around without defining the economics. Interviewers use it to test whether you understand what equity actually pays for. CFDF is a bridge, not a slogan on a marketing cover.
The short answer
"Cash-free debt-free means the headline enterprise value assumes the buyer gets the operating business with no excess cash and no interest-bearing debt at closing. Equity value is then EV minus actual net debt and other scheduled adjustments, often with a working capital peg so the balance sheet delivered is normal. You are buying operations, not a random pile of cash and debt."
Why CFDF exists
Buyers want to price the operating company on a like-for-like basis. Sellers want credit for cash left in the business and clarity on debt that must be repaid or assumed. CFDF is the market shorthand for that split. Without it, every negotiation becomes an argument about whether the EV already included a temporary cash sweep or a revolver draw.
The bridge you must be able to draw
Equity value intuition
Equity Value ≈ Enterprise Value − Net Debt ± Other adjustments ± WC peg true-up Net Debt ≈ Interest-bearing debt − cash (definitions live in the SPA schedule)
Say the words "schedule in the purchase agreement" in interviews. Concept is shared. Line items are negotiated. Pair with enterprise vs equity value and a net debt bridge.
What usually counts
| Item | Typical CFDF treatment |
|---|---|
| Bank debt, bonds, drawn revolver | Debt (subtract) |
| Excess cash | Reduces net debt / increases equity value |
| Minimum operating cash | Often stays; not treated as excess |
| Restricted cash | Often excluded from excess cash |
| Operating working capital | Usually via peg, not inside EV |
| Capital leases / debt-like items | SPA-defined; call them out |
| Preferred / seller notes | Often debt-like if interest-bearing |
| Transaction bonuses unpaid | Frequently debt-like |
Mini example
Agreed CFDF EV: $500.
Cash at close: $40. Interest-bearing debt: $120.
Simple equity value ≈ 500 − (120 − 40) = $420, before WC peg, fees, and other adjustments.
If minimum cash must be $15, only $25 may count as excess depending on the SPA. That single definition can move equity value by $15.

Working capital peg interaction
CFDF answers cash and debt. The peg answers whether AR, inventory, and AP are normal. A seller can game cash by stretching payables. The peg exists to stop that. Full guide: working capital peg.
If you only adjust net debt and ignore a thin WC balance sheet, you overpay for a company that just stretched AP into closing. Interviewers love that trap.
CFDF vs locked box
Price adjusts for actual cash, debt, and NWC at close.
Equity value fixed at a historical locked-box date; leakage rules protect the buyer afterward.
European deals lean locked box more often. US middle market still talks CFDF constantly. Know both names. Do not mash them into one explanation. If asked which is "better," say it depends on certainty, leakage protection, and negotiation leverage, not slogans.
LBO sources and uses link
Your equity check is not "EV minus some debt you guessed." It is the SPA economics plus fees, refinance amounts, and minimum cash. Forgetting refinance of existing debt or financing fees breaks sources and uses. See sources and uses.
In a model, CFDF EV is the operating price. The cash wire the sponsor sends is equity funding after debt payoffs, fees, cash retained, and true-ups. Mixing those two numbers is a classic fail.
Interview follow-ups worth drilling
- Is a seller note debt for CFDF? Usually yes if interest-bearing; read the schedule.
- Are transaction expenses debt-like? Often yes if unpaid at close.
- How do you treat overfunded vs underfunded pensions at a high level?
- What if cash is restricted for a customer deposit?
- How does a WC peg true-up change equity value after close?
Common fails
- Equating CFDF with "equity value equals EV"
- Ignoring minimum cash
- Putting operating WC into net debt
- Forgetting that EV is the agreed operating price, not the wire the sponsor sends
- Treating every cash balance as excess without reading restrictions
35-second verbal
"Cash-free debt-free means EV prices the operations as if excess cash and interest-bearing debt are normalized out. Equity value bridges from EV through net debt and other SPA adjustments, often with a WC peg. I always ask what the debt-like and cash schedules include, especially minimum cash."
Practice
Rebuild the $500 EV example with: minimum cash $15, unpaid transaction bonus $5, seller note $20. Recalculate equity value and narrate each line. Then explain how a $10 WC shortfall versus the peg would change the true-up.
