Working Capital Adjustments in LBO Purchase Agreements

A working capital adjustment in an LBO is a mechanism that reconciles the target company’s balance sheet on closing day against a pre-agreed baseline, ensuring the seller and buyer split the cost of any unexpected changes in cash, receivables, inventory, and payables. When actual working capital deviates from the “normalised” or target level, the purchase price is adjusted dollar-for-dollar, making this clause critical to both parties’ deal economics.

Why Working Capital Matters in an LBO

A company’s working capital—the difference between current assets (cash, receivables, inventory) and current liabilities (payables, accrued expenses)—varies with the business cycle and the seller’s operating choices. Without a working capital adjustment, the buyer inherits all the risk of walking into a cash-starved or inventory-heavy balance sheet on day one, or the seller keeps the benefit of an artificially tight one. The adjustment ensures both parties split the risk fairly and align the deal price with the state of the business at close.

In a leveraged buyout, where the buyer is relying on debt financing to fund much of the purchase and needs predictable cash to service that debt, the working capital baseline is especially critical. A buyer who discovers on day one that payables have shrunk or inventory has ballooned will immediately face a cash crunch—money that was meant to pay down debt must instead fund operations.

The Normalised Working Capital Peg

Rather than simply comparing actual working capital at close to actual working capital at some historical date, the parties agree on a normalised working capital target. Normalisation strips out one-time, seasonal, or non-recurring items that distort the true operating need.

Common adjustments to arrive at a normalised number include:

• Seasonal swings. A retail company might have bloated inventory before the holiday season or payables spiked just before year-end. The peg is adjusted to reflect a “normal” operating level.
• Non-recurring receivables or payables. Litigation settlements, one-time vendor bonuses, or customer deposits are removed.
• Accrued bonuses or restructuring costs that the seller was planning to fund before close (and thus reduce the cash outflow the buyer needs to make).
• Customer-specific balances that are unrelated to ongoing operations (e.g., a large contract that will terminate post-close).

The normalised working capital is typically expressed as a dollar amount (e.g., “$5 million”) or as a percentage of revenue (e.g., 8% of trailing twelve-month revenue). In practice, normalisation is one of the most contentious elements of an LBO—the seller wants the target set conservatively (high) so they receive a refund if actual working capital is lower, while the buyer wants it high (so they avoid paying a premium for a lean balance sheet that the seller has engineered).

How the True-Up Works

On the reference date (typically 30–45 days before close), the seller provides a working capital calculation based on a pro forma balance sheet. This becomes the “target” (or “peg”). For example, if the target is $5 million and the buyer is assuming the business needs exactly that amount to operate normally, the parties agree on that figure contractually.

At close, the parties prepare an actual balance sheet. If actual working capital is $5.2 million (higher than the $5 million target), the buyer overpaid by $200,000 relative to the agreed baseline. The seller therefore owes the buyer a $200,000 refund (sometimes held from an escrow account set aside specifically for this purpose). Conversely, if actual working capital is $4.8 million, the buyer underpaid by $200,000, and the buyer owes the seller an additional $200,000.

The mechanics are usually a dollar-for-dollar adjustment: every dollar of excess working capital reduces the seller’s cash at close (or increases the escrow holdback), and every dollar of deficit adds to the amount the buyer must pay or increases the seller’s claim in the final true-up.

Post-Close Dispute Resolution

The closing balance sheet and the working capital true-up calculation are typically settled 60–120 days after close, allowing time for the parties to audit and verify the numbers. Most purchase agreements include a threshold (sometimes called a “collar” or “dead band”)—if the adjustment is under, say, $250,000, it is waived and no payment changes hands. This avoids trivial disputes.

If the parties cannot agree on the final adjustment, the purchase agreement typically specifies an independent accounting firm to review both calculations and render a binding determination. This review is usually limited to the specific line items in dispute and is relatively quick, though it can be expensive ($25K–$75K or more depending on complexity).

Escrow and Holdbacks

To mitigate the risk that the seller will be unreachable or insolvent if a large true-up adjustment is discovered post-close, most LBO agreements require the buyer to place a portion of the purchase price into an escrow account (typically held by a third-party escrow agent). Common escrow percentages are 10–20% of the equity purchase price, held for 12–24 months.

The escrow serves multiple purposes: it funds the working capital true-up if the buyer is owed a refund, it covers breaches of seller reps and warranties, and it provides security if the buyer wants to reverse previous adjustments they believe were incorrect. A portion of the escrow (the “working capital escrow”) may be released early once the final working capital adjustment is agreed; the remainder (the “general escrow”) typically remains for the full term to cover other post-close disputes.

Working Capital in the Equity Return Calculation

For the sponsor (the private equity firm), the working capital adjustment directly affects the equity cheque required at close and therefore the internal rate of return (IRR) of the deal. A larger working capital adjustment due to the buyer means the sponsor pays less upfront cash at close, which improves the cash-on-cash multiple and IRR. Conversely, an unfavorable adjustment (the seller owes nothing, or the buyer owes more) increases the cash outlay and depresses returns.

This is why sponsors spend considerable time in due diligence modeling working capital scenarios—validating the seller’s normalisation assumptions, stress-testing seasonality, and understanding the company’s cash conversion cycle. Even a $500,000 swing can shift the IRR by 1–2 percentage points on a mid-market LBO.

Common Pitfalls

• Asymmetric normalisation. One side normalises aggressively to inflate the peg, creating a dispute at close. Clear, documented working capital standards (often based on industry benchmarks or the company’s historical levels) reduce risk.
• Moving inventory or cash before close. Sophisticated sellers have been known to shift cash out or buy excess inventory to artificially alter working capital. Reps and warranties addressing balance sheet integrity, and a buyer’s detailed closing condition on working capital levels, are essential safeguards.
• Revenue seasonality surprises. If the reference date falls in a low-revenue month, the actual working capital at close (in a high-revenue month) can be much higher. Working capital pegs tied to a percentage of revenue, or adjusted for seasonality, address this.
• Underfunded customer deposits. In some businesses, customer deposits flow in before inventory is purchased. A seller who cashes deposits early will show low payables and low inventory, appearing lean—until the buyer must fulfill those orders post-close.
