One of the most common and costly surprises in a business sale occurs not during the negotiation of the headline purchase price but at closing, when the actual amount wired to the seller is calculated. Founders frequently agree to a purchase price of, say, $20 million and then receive substantially less — sometimes hundreds of thousands or even millions of dollars less — because of adjustments built into the deal structure that were not fully understood when the transaction was negotiated. These adjustments arise from three principal sources: working capital adjustments, the treatment of debt at closing, and the treatment of cash. Together, they constitute the closing mechanics of a deal, and understanding them is essential to knowing what you will actually take home.
What Is a Cash-Free, Debt-Free Transaction?
Most M&A transactions involving private companies are structured on what is called a cash-free, debt-free basis. This phrase describes the fundamental premise on which the purchase price is set: the buyer is acquiring the operating business with its normal level of working capital, but without any of the company’s cash (which goes to the seller) and without any of the company’s interest-bearing debt (which the seller must repay at or before closing). Understanding this premise is the starting point for understanding all of the closing adjustments.
The rationale for the cash-free, debt-free structure is straightforward. When a buyer values a business based on its earnings — applying a multiple to EBITDA, for example — the resulting valuation reflects the operating performance of the business independent of how it is financed and independent of how much cash happens to be sitting in the bank on the day of sale. Whether the company had $5 million or $500,000 in cash at the time of sale does not change what the business is worth as an operating enterprise. So the structure says: the buyer gets the operating business at the agreed value; the seller keeps the cash (or has it paid out at closing as part of the proceeds); and the seller is responsible for paying off any interest-bearing debt before or at closing.
In practice, a cash-free, debt-free deal is implemented through adjustments to the purchase price. The basic formula is: Purchase Price = Enterprise Value – Net Debt + Excess Cash + Working Capital Adjustment. Each of these components can shift the actual amount paid at closing, sometimes in ways that significantly surprise sellers who focus only on the enterprise value number.
How Debt Is Defined and Treated at Closing
In the context of M&A closing adjustments, debt is typically defined more broadly than just bank loans or lines of credit. The purchase agreement will contain a specific definition of the term ‘indebtedness,’ and this definition almost always includes bank debt, capital leases, and seller notes, but it often also includes items that founders do not think of as debt: deferred revenue (to the extent it represents cash received for services not yet delivered), unpaid transaction costs (legal fees, banker fees, and similar costs incurred in connection with the sale), obligations to make payments under change-of-control provisions in employee agreements, unfunded pension or profit-sharing obligations, accrued interest, and sometimes income tax liabilities that have accrued through the closing date.
This definitional breadth can produce significant surprises. Consider a company with $2 million in bank debt, $500,000 in capital lease obligations, $800,000 in transaction costs (banker fees and legal fees), and $400,000 in change-of-control bonuses triggered by the sale. In a deal structured with an enterprise value of $20 million, the indebtedness to be paid or deducted at closing totals $3.7 million, leaving net proceeds of $16.3 million — before any working capital adjustment. If the seller’s banker presented the deal as a $20 million transaction, that $3.7 million gap between the headline number and the actual proceeds can feel very jarring.
Founders can and should negotiate what is included in the definition of indebtedness. Transaction costs, in particular, are sometimes excluded from the debt definition and simply treated as closing expenses that are paid by the respective parties. How the definition is negotiated in the LOI and in the purchase agreement has real dollar consequences, and your attorney should examine the definition carefully and push back on inclusions that are inconsistent with standard market practice or that capture items the seller does not consider to be genuine debt of the business.
The Working Capital Adjustment: How It Works
The working capital adjustment is the mechanism that ensures the buyer receives the business with a normal, agreed-upon level of working capital — not more, not less. Working capital is defined in the purchase agreement as current assets minus current liabilities, calculated in accordance with specified accounting principles and applying specific definitions agreed to by the parties. The adjustment works as follows: before closing, the parties agree on a target working capital level that represents what the business normally carries. At closing, the actual working capital is calculated. If the actual working capital exceeds the target, the purchase price goes up by the difference. If the actual working capital is below the target, the purchase price goes down by the difference.
The purpose of this adjustment is to prevent gaming. Without a working capital adjustment, a seller would have a strong incentive to reduce working capital before closing — by collecting receivables as aggressively as possible, delaying payments to vendors, drawing down inventory, and similar measures — and then pocketing the released cash as part of the proceeds while leaving the buyer with a business that is short on the working capital needed to operate. The working capital adjustment corrects for this by effectively saying: whatever the business normally needs to operate, it should arrive with that amount.
The working capital target is usually set equal to the average or trailing working capital of the business over a recent period, often twelve months. But how exactly the target is calculated, which line items are included and which are excluded, and which accounting policies are applied in measuring working capital are all matters that need to be precisely specified in the purchase agreement. Ambiguity in any of these specifications virtually guarantees a post-closing dispute.
Common sources of post-closing working capital disputes include the treatment of deferred revenue (which some buyers include as a current liability in the working capital calculation, reducing it, and some sellers argue should be excluded), the treatment of accrued expenses (particularly accrued bonuses and vacation pay), the treatment of customer deposits, the valuation of inventory (particularly write-offs for slow-moving or obsolete inventory), and the treatment of tax receivables and payables. Each of these items can move the working capital calculation by hundreds of thousands of dollars, and the cumulative effect can be significant.
The Closing Statement and the True-Up Process
Because the actual working capital, debt, and cash at closing cannot be precisely known until the deal closes, most M&A transactions use a two-step approach. At closing, the parties use an estimated closing statement to calculate the initial purchase price payment based on their best estimate of working capital, debt, and cash at the closing date. After closing, the buyer prepares a final closing statement reflecting the actual figures. The parties then go through a true-up process: if the buyer’s final calculation shows that the initial payment was too high (because actual working capital was below target, or actual debt was higher than estimated), the seller must pay the difference to the buyer. If the final calculation shows the initial payment was too low, the buyer pays the difference to the seller.
The true-up process is a significant source of post-closing disputes. The buyer prepares the final closing statement, which gives them an inherent advantage: they control the first draft and can make calculations in ways that favor their position. A well-negotiated purchase agreement will give the seller a specified period to review the buyer’s closing statement, provide the seller with access to the books and records used to prepare it, and establish a clear dispute resolution process — including a mechanism for engaging an independent accounting firm to resolve disagreements. Without these protections, sellers can find themselves in a position where they must either accept the buyer’s calculation or litigate to challenge it.
Some transactions are structured with a locked-box mechanism instead of the closing statement approach. In a locked-box structure, the purchase price is fixed at signing based on an agreed-upon balance sheet as of a date before closing (the locked-box date), and no post-closing adjustment is made. The locked-box approach eliminates the uncertainty of the true-up process, but it transfers the risk of changes between the locked-box date and closing to the buyer and requires very precise drafting to define what ‘leakage’ from the box between signing and closing is permissible. Locked-box structures are more common in European transactions than in US deals, but they do appear in US M&A practice, particularly in large transactions.
Why Founders Are Often Surprised by the Math at Closing
There are several reasons why founders consistently underestimate how much the closing adjustments will affect their net proceeds. The first is that investment bankers and buyers both tend to discuss the deal in terms of enterprise value or headline purchase price, which is the most favorable number and the one that goes in the press release. The adjustments come later and are presented as mechanical calculations rather than negotiated terms, which creates the impression that they are simply inevitable rather than something that can be influenced.
The second reason is that the working capital target, in particular, is easy to underestimate. Founders often have a general sense of what they think the business carries in working capital but have not modeled it precisely across all four seasons of the business. If the working capital target is set based on a period that included an unusually high level of receivables, and closing occurs during a period with lower receivables, the adjustment will be unfavorable. Conversely, if the target is set during a low period and closing occurs during a high period, the adjustment will be favorable. Being precise about the working capital target and ensuring that it is set based on a methodology that reflects your business’s normal operations is one of the most important financial negotiations in any transaction.
The third reason is that the definition of debt, as discussed above, often captures items that the seller did not expect. Transaction costs in particular — which can total one to three percent of deal value on a typical middle-market transaction — frequently end up being treated as debt-like items that reduce the proceeds to the seller, and founders sometimes do not fully appreciate the magnitude of these costs until they see the closing statement.
What to Watch For During Negotiation
Several specific protections are worth negotiating with respect to closing adjustments. On the working capital target, ensure that it is set based on a methodology that is clearly specified, that the definition of working capital excludes any items that are separately accounted for in the debt or cash calculation, and that the historical period used to establish the target is representative of the business’s normal operating cycle. If your business is seasonal, a trailing twelve-month average is generally more representative than a single-point measurement.
On the closing statement process, negotiate adequate time to review the buyer’s proposed closing statement, full access to the records used to prepare it, and a clear dispute resolution mechanism. A sixty-day review period with a thirty-day dispute notice window and referral to a mutually agreed accounting firm for unresolved disputes is a reasonable and market-standard structure.
On the definition of indebtedness, review it line by line with your attorney. Challenge inclusions that are inconsistent with market practice or that capture items your business does not consider to be genuine financial obligations. The definition of what constitutes debt at closing is a negotiable term, and sellers who engage seriously with it can sometimes exclude millions of dollars of items that would otherwise reduce their proceeds.
Perhaps most importantly, model the expected closing adjustments before you accept the LOI. Your banker and accountant should be able to produce a realistic estimate of the net proceeds after adjustments based on your current financial statements. Going into a transaction with a clear and realistic expectation of what you will actually receive — rather than what the headline purchase price suggests — is one of the most practical ways to protect yourself from the surprise that derails too many founders at the finish line.
