Net Debt Explained: What Counts as Debt

Introduction

Ask a candidate to walk you through net debt and most will fire back the textbook line: total debt minus cash. That is the easy half. The half that separates a clean answer from a fumbled one is everything that sits between the obvious bonds and the obvious cash: finance leases, pension deficits, preferred stock, noncontrolling interests, convertible bonds, and cash that looks spendable but is not. These are the enterprise value bridge items, and they are where interviewers probe because they reveal whether you actually understand why the bridge exists.

Net debt is not an accounting definition you can pull straight off the balance sheet. It is a judgment call about which claims are debt-like enough to belong in the bridge from equity value to enterprise value, and which cash is genuinely available to retire those claims. Get the judgment items right and you demonstrate that you grasp the logic, not just the formula. This post walks through each item one at a time, explains the reasoning behind including or excluding it, builds a fully worked bridge from equity value to enterprise value, and shows how the exact same items resurface when a deal is negotiated on a cash-free, debt-free basis.

Before cataloguing the judgment items, it helps to be crystal clear on why net debt matters at all. If you cannot articulate the purpose of the bridge, you will guess at the individual items instead of reasoning through them.

Enterprise Value Is Capital-Structure Neutral

Enterprise value measures the total value of a company's core operations, independent of how those operations are financed. Two companies with identical factories, contracts, and cash flows should have the same enterprise value even if one is funded entirely with equity and the other is loaded with debt. Equity value, by contrast, is what belongs to common shareholders after every more senior claim is satisfied. The bridge between the two is simply the sum of all non-common claims on the business, net of cash that could be used to extinguish them.

That framing is the whole game. Every item you add or subtract in the bridge is you answering one question: is this a claim on the enterprise that ranks ahead of common equity? Debt ranks ahead. So does a pension the company must fund and preferred stock that gets paid first. Cash sitting in the operating account offsets those claims because it could be swept out to repay them. If you want the full conceptual treatment of how the two numbers relate, our enterprise value versus equity value guide is the parent explainer this post builds on.

Net Debt

Net debt is a company's total interest-bearing debt, including bonds, term loans, revolver draws, and finance lease liabilities, minus cash and cash equivalents that are actually available to repay that debt. It is the core building block of the enterprise value bridge and a headline measure of financial leverage.

The Bridge Direction: Equity to Enterprise and Back

In comparable company analysis you usually start from a known equity value (share price times diluted shares) and add net debt plus the other bridge items to reach enterprise value, which you then divide by EBITDA to get a multiple. In a DCF you do the reverse: you discount unlevered free cash flows to an enterprise value and subtract net debt and the other items to get to equity value per share. Same items, opposite direction. The consistency point that trips people up is that whatever you put in the bridge must match what your operating metric already captures, a theme that returns repeatedly below, especially with leases.

Start with the items nobody argues about. These are the contractual borrowings that sit plainly on the liabilities side of the balance sheet and carry a stated interest rate.

Term Loans, Bonds, and Revolver Draws

Term loans, senior notes, high-yield bonds, and any drawn balance on a revolving credit facility are all straightforward debt. They are contractual obligations to pay interest and repay principal, they rank ahead of equity, and they belong in net debt at their face or book value for a quick calculation. In a precise valuation you would consider the market value of publicly traded bonds, but for interview purposes book value is the accepted shortcut. An undrawn revolver is not debt because nothing has been borrowed; only the drawn portion counts.

Short-Term Debt and Current Maturities

Do not forget the current liabilities. The current portion of long-term debt, short-term borrowings, and commercial paper are all interest-bearing and all count. A common sloppy answer pulls only the long-term debt line and ignores the piece maturing within twelve months. Both halves are debt, and lenders certainly do not stop counting a bond just because it comes due next year.

Net debt trips up more candidates than DCF math: Practice valuation and enterprise-value questions with worked answers, start practicing interview questions for free and find your gaps before an interviewer does.

Here is the real content of the interview. Each item below is debt-like in some way, and for each one the reasoning matters more than the yes-or-no answer. The table gives you the quick reference; the sections that follow give you the why.

Finance Leases and the Operating Lease Trap

Leases are the single most reliable place to catch a candidate out, and the trap has gotten sharper since the accounting changed. Under ASC 842 in the United States and IFRS 16 internationally, nearly all leases now appear on the balance sheet as a right-of-use asset and a matching lease liability. That balance sheet presence tempts people to add every lease liability to net debt. Do not do it reflexively.

The rule is a consistency rule between the liability and your operating metric. Under US GAAP, a finance lease is split into depreciation and interest, both below EBITDA, so the finance lease liability is genuinely debt-like and belongs in net debt. An operating lease under US GAAP, however, keeps a single straight-line lease expense that sits above EBITDA, exactly where rent used to sit. The IFRS 16 leases standard takes the opposite path and puts almost every lease into a single on-balance-sheet model, which is why the geography of the expense, and therefore the bridge treatment, differs across regimes. Because that expense is already reducing your EBITDA, adding the operating lease liability to enterprise value would double-count it. So with a standard EBITDA multiple under US GAAP, you exclude operating lease liabilities.

The deeper mechanics of classification, the journal entries, and how the two regimes diverge are covered in our dedicated piece on operating versus finance leases. For net debt, remember the one-liner: match the lease treatment in your value to the lease treatment in your multiple.

Pension Deficits as Debt-Like Obligations

An underfunded defined-benefit pension is one of the cleanest examples of a debt-like item. If a company has promised retirees more than its pension plan assets can cover, the gap is a real obligation the company must eventually fund out of future cash flows. That is economically indistinguishable from owing money to a lender, so the net underfunded status is added to the bridge, ideally on an after-tax basis because pension contributions are typically tax-deductible.

The numbers can be enormous. IBM disclosed underfunded defined-benefit plans with a combined funded status of roughly $10.1 billion as of December 31, 2024, per its annual report on SEC EDGAR. For a company with a large legacy workforce, ignoring a deficit that size would understate enterprise value materially. Note the mirror case: an overfunded plan is a debt-like asset and can be subtracted, though analysts often treat a surplus cautiously because it is not freely distributable.

Pension Deficit

A pension deficit, or underfunded status, is the shortfall between a defined-benefit plan's projected benefit obligation and the fair value of its plan assets. Because the sponsoring company must fund that gap over time, it is treated as a debt-like item and added to the enterprise value bridge, usually net of the associated tax benefit.

Preferred Stock: A Senior Claim on Common

Preferred stock is called stock, but for the bridge it behaves like debt. Preferred holders receive dividends before common shareholders and stand ahead of common in liquidation. Because enterprise value must capture every claim senior to common equity, preferred stock is added at its liquidation or market value. The only nuance is genuinely equity-like preferred that converts on the same terms as common, which you would treat as part of the diluted share count instead, but the default treatment for straight preferred is a bridge addition.

Noncontrolling Interests: A Consistency Add, Not Debt

Noncontrolling interest, also called minority interest, is the classic "why do you add it?" question, and the honest answer is that it is not debt at all. It is there for consistency. When a parent owns more than half of a subsidiary, accounting rules make it consolidate 100% of that subsidiary's revenue and EBITDA, even the portion it does not own. Your EBITDA in the denominator therefore reflects the whole subsidiary. To keep the multiple honest, enterprise value in the numerator must also reflect the whole subsidiary, so you add the value of the slice owned by outside shareholders, the noncontrolling interest.

Skip that add and you divide a 100% enterprise value by a 100% EBITDA using a numerator that only captures the parent's share, and the multiple is distorted. The mechanics of consolidation versus the equity method, and when each applies, are laid out in our explainer on minority interest and the equity method.

Convertible Bonds: In or Out of the Money

Convertible bonds sit on a fence, and their treatment depends on where the stock trades relative to the conversion price. If the converts are out of the money, meaning the share price is below the conversion price, holders will not convert and the instrument behaves like ordinary debt, so you treat it as debt in net debt. If the converts are in the money, holders will convert to equity, so the more precise approach treats them as additional shares in the diluted count rather than as debt, often using the if-converted method. Mixing both, counting a convert as debt and as shares at the same time, double-counts it. The instrument mechanics, coupon and conversion features, and dilution math are covered in our guide to convertible bonds and notes.

The cash side of net debt is not as simple as sweeping the entire cash line off the balance sheet. The question you should always ask is whether the cash is genuinely available to repay debt. Some of it is not.

Restricted Cash and Minimum Operating Cash

Restricted cash, such as balances pledged as collateral, held in escrow, or reserved to service a specific facility, is not available to repay general debt, so it usually does not reduce net debt. Beyond formally restricted cash, every operating business needs a minimum working balance to run: to make payroll, pay suppliers, and cover the timing gaps in the cash conversion cycle. That minimum operating cash is not truly excess either. A careful analyst subtracts only cash above the operating minimum, though for a quick interview answer subtracting total cash net of any restricted balance is accepted.

Overseas Cash and Tax Friction

Cash trapped in foreign subsidiaries carries a subtler problem. Repatriating it can trigger tax, so a dollar of overseas cash may be worth less than a dollar of domestic cash for the purpose of paying down debt at the parent. In practice, analysts sometimes haircut overseas balances or note the friction rather than netting the cash at full face value. The point for an interview is awareness: not all cash is equal, and geography and tax can make reported cash overstate what is genuinely deployable.

Concepts stick when you run the numbers. Take a hypothetical mid-cap industrial trading at $40.00 per share with 100 million shares outstanding, giving an equity value, or market capitalization, of $4,000 million. Its balance sheet and off-balance-sheet obligations look like this.

Notice what is in and what is out. The finance lease liability of $120 million is inside total debt. The company also carries $300 million of operating lease liabilities that do not appear anywhere in the bridge, because we are using an EBITDA multiple under US GAAP and that lease cost is already sitting above the EBITDA line. Reported cash is $500 million, but $50 million is restricted collateral, so only $450 million nets against debt. The high-level relationship the table expresses is:

Walking the same figures in order makes the direction of travel concrete, from the market capitalization at the top down to the enterprise value the multiple is built on.

Run it in reverse and the logic holds: if a DCF produced an enterprise value of $5,950 million, you would subtract net debt of $1,420 million, the pension deficit, the preferred, and the noncontrolling interest to arrive back at $4,000 million of equity value, then divide by 100 million shares for a $40.00 implied price. The bridge is a two-way street, and the items are identical in both directions.

Net debt is not just a comps exercise. The identical list of judgment items reappears at the negotiating table, because most private company sales are struck on a cash-free, debt-free basis. Understanding this connection is what turns a memorized formula into applied knowledge.

Cash-Free, Debt-Free and the Debt-Like Items Schedule

Under a cash-free, debt-free deal, the parties agree an enterprise value, and the seller keeps the cash while paying off the debt at closing. The purchase price then bridges from that enterprise value down to the equity value the buyer actually pays, adjusting for the company's real debt, cash, and net working capital at the closing date. Every debt-like item is a dollar-for-dollar reduction in what the seller nets, which is exactly why buyers and sellers fight over the definition of "debt-like" in the purchase agreement.

Cash-Free, Debt-Free (CFDF)

Cash-free, debt-free is the standard basis for private company M&A: the buyer acquires the business assuming it has no cash and no debt, so the seller sweeps the cash and repays borrowings at closing. The agreed enterprise value is then bridged to the final equity purchase price by adjusting for actual debt, debt-like items, cash, and a net working capital true-up.

Buyers push to classify as many items as possible as debt-like: deferred purchase consideration, unpaid capital expenditure, accrued bonuses, unfunded pensions, deferred revenue, and outstanding earn-outs can all end up on a debt-like items schedule. Sellers resist, because each inclusion lowers their proceeds. The negotiation over these definitions is where real dollars change hands, and it interacts closely with the separate net working capital adjustment, which our guide on net working capital adjustments in M&A unpacks in detail.

Debt-Like Items

Debt-like items are obligations that are not conventional bank debt but are treated as debt when pricing a deal, because the buyer will have to fund or assume them. Common examples include underfunded pensions, deferred consideration, accrued but unpaid bonuses, and earn-outs. In a cash-free, debt-free sale they reduce the equity price the seller receives.

Structuring matters enormously here, and the scale is easy to underestimate: on a smaller deal, a pension or earn-out shortfall of a few million can swing double-digit percentages of the equity check, while on a large deal the same absolute amount barely registers. That is why sophisticated sellers negotiate the debt-like definitions in the letter of intent, before diligence hardens the buyer's leverage.

Two questions come up so often they are worth rehearsing until the answers are reflexive. Both test whether you understand the reasoning, not the label.

"Is an Operating Lease Debt?"

The strongest answer is "it depends on the metric, and here is why." Under US GAAP, an operating lease liability sits on the balance sheet, but the lease expense is still above EBITDA, so if you are using an EBITDA multiple you exclude the liability to avoid double-counting. Under IFRS 16, or if you are working with EBITDAR, the rent is not in your operating metric, so the lease obligation belongs in the bridge. The interviewer is checking whether you reach for the consistency principle or just parrot "it is on the balance sheet, so it is debt." How enterprise value multiples are actually built and compared is worth revisiting in our overview of common valuation multiples.

"Why Do You Add Minority Interest?"

Answer with the consistency logic, not a definition. You add noncontrolling interest because consolidated EBITDA already includes 100% of a majority-owned subsidiary, so enterprise value must capture 100% of that subsidiary too, including the piece owned by outside shareholders. It is not that you owe the minority holders money in a debt sense; it is that the numerator and denominator of your multiple have to describe the same economic entity. Candidates who say "because it is a claim on the company" are half right; the precise reason is comparability of the multiple.

Net debt is a reasoning exercise disguised as a formula. The mechanical part, total debt minus cash, is table stakes. The judgment items are the test.

If you take one habit away from this, make it the reflex to ask "why" for every line you add or subtract. Every item in the net debt bridge answers the same question, whether this claim ranks ahead of common equity and whether the cash could actually be used to settle it. Bonds, leases, pensions, preferred, and minority interest all earn their place in the bridge for a specific reason, and the operating lease and minority interest questions are favorites precisely because they reward reasoning over memorization.

Work through the bridge on real filings until the judgment calls feel automatic. Pull a lease-heavy retailer and a pension-heavy industrial, build the bridge both ways, and check that your enterprise value ties out from equity value and back. Once the logic is second nature, the interview version becomes a thirty-second answer, and the deal version, where these definitions decide who keeps millions of dollars at closing, will make intuitive sense too.
