Net Working Capital Peg
Executive Summary
Key Takeaways
- ✓ The net working capital peg is a target level of net working capital established during due diligence and written into the purchase agreement as the benchmark against which the actual closing balance is measured.
- ✓ Any shortfall below the peg reduces the purchase price, and any excess above it increases the purchase price, on a dollar-for-dollar basis, making the peg's calculation one of the most direct pricing mechanics in the entire transaction.
- ✓ The peg is typically calculated as a normalized trailing average, adjusted for known seasonality, rather than a single point-in-time balance, since working capital naturally fluctuates across a business's operating cycle.
- ✓ Disputes over the net working capital adjustment are among the most common sources of post-closing transaction disputes, usually centered on inconsistent application of the accounting methodology between the peg calculation and the closing balance calculation.
- ✓ A well-drafted purchase agreement specifies the exact accounting policies, line-item definitions, and calculation methodology for both the peg and the closing balance in identical terms, to minimize the risk of a methodology dispute after closing.
Definition¶
The net working capital peg is a target level of net working capital, established during Financial Due Diligence and written into the purchase agreement, against which the target's actual net working capital balance at closing is measured. Any shortfall below the peg reduces the purchase price, and any excess above it increases the purchase price, on a dollar-for-dollar basis.
Calculation Methodology¶
The peg is typically calculated as a normalized trailing average — commonly twelve months — adjusted for known seasonality, rather than as a single point-in-time balance. A business with seasonal working capital swings (a retailer building inventory ahead of a peak season, for example) would produce a misleadingly high or low peg if measured only at a single unfavorable or favorable date, which is why a normalized average across a representative operating cycle is standard practice.
Net Working Capital = Current Assets (excl. cash) − Current Liabilities (excl. debt)
Peg = Normalized trailing-average NWC, adjusted for disclosed seasonality
Purchase Price Adjustment = Actual Closing NWC − Peg
(positive: increases purchase price; negative: reduces purchase price)
Why Methodology Consistency Matters¶
The purchase agreement should specify identical accounting policies, line-item definitions, and calculation methodology for both the peg (calculated during diligence) and the actual closing balance (calculated at or after closing). A difference in inventory valuation method, bad debt reserve policy, or which specific line items are included between the two calculations is one of the most common sources of post-closing dispute — not because the underlying working capital genuinely differed, but because the two calculations were not performed on a truly comparable basis.
Audit Considerations¶
- Confirm the peg's calculation methodology, including the trailing period used and any seasonality adjustment, is fully disclosed and defensible
- Confirm the purchase agreement specifies identical accounting policies and line-item definitions for both the peg and the actual closing balance calculation
- Confirm the net working capital adjustment mechanism is explicitly reflected in the transaction model's sources and uses and equity value reconciliation
Common Errors¶
| Error | Description | Risk |
|---|---|---|
| Non-representative peg period | Peg calculated on a single date or unrepresentative period rather than a normalized average | Peg does not reflect genuine ongoing working capital needs |
| Methodology inconsistency | Different accounting treatment applied to the peg versus the actual closing calculation | Post-closing dispute over the resulting adjustment |
| Undefined line-item scope | Ambiguity over which specific balance sheet items are included in "working capital" | Disagreement over the adjustment amount at closing |
| Model omission | Net working capital adjustment mechanism not explicitly built into the acquisition model | The purchase price adjustment is not properly reconciled in the deal's own pricing model |

Frequently Asked Questions
What is the net working capital peg?
A target level of net working capital, established during due diligence and written into the purchase agreement, against which the target's actual net working capital balance at closing is measured — any shortfall reduces the purchase price and any excess increases it, dollar for dollar.
How is the net working capital peg typically calculated?
As a normalized trailing average — often twelve months — adjusted for known seasonality, rather than a single point-in-time balance, since working capital naturally fluctuates across a business's operating cycle and a single-date figure could be unrepresentatively high or low.
Why are net working capital adjustments a common source of post-closing disputes?
Because disputes usually center on inconsistent application of accounting methodology between how the peg was originally calculated during due diligence and how the actual closing balance is calculated — a difference in inventory valuation method or reserve policy between the two calculations, for example, can produce a materially different adjustment than either party expected.
How can a purchase agreement minimize the risk of a working capital dispute?
By specifying the exact accounting policies, line-item definitions, and calculation methodology for both the peg and the actual closing balance in identical, unambiguous terms, removing room for inconsistent application between the two calculations.
Does the net working capital peg affect the acquisition model directly?
Yes — it is typically built into the acquisition model as an explicit purchase price adjustment mechanism, reconciling the enterprise value agreed at signing to the actual equity consideration paid at closing, alongside the net debt bridge — see the existing Sources and Uses glossary page.

Financial Due Diligence
Financial due diligence investigates a target company's historical financial performance — earnings quality, working capital trends, net debt, and off-balance-sheet obligations — to establish a reliable, normalized baseline before a transaction is priced. It is distinct from a forward-looking financial model review: financial due diligence establishes what actually happened historically and whether reported earnings are a reliable indicator of sustainable performance, while a model review tests whether the forecast built on top of that baseline is structurally sound. This guide covers financial due diligence's core areas and how its outputs — normalized EBITDA, the net working capital peg, net debt — flow directly into deal pricing.
M&A and Transaction Due Diligence
Transaction due diligence is the structured process by which a party to a proposed transaction — most often a buyer, but also a seller preparing for sale or a lender financing the deal — investigates a target business before committing capital. It is organized into distinct workstreams (financial, commercial, operational, technical, legal, tax, ESG), run from one of three process postures (buy-side, sell-side, or vendor), and its findings feed directly into the financial model used to price the transaction and support the investment decision. This page is the hub for the Knowledge Centre's transaction due diligence content: what due diligence is, how each workstream and process posture differs, and how model risk specifically enters a transaction — the angle this platform is built to address in depth.
Working Capital Schedule
A working capital schedule is the section of a financial model that calculates the period-by-period movements in a company's or project's net current assets — the difference between current assets (principally trade receivables) and current liabilities (principally trade payables and accrued liabilities). It translates revenue and cost accruals from the income statement into actual cash flows by capturing the timing difference between when economic activity is recognised and when cash is received or paid. Working capital is defined as: The working capital schedule calculates the change in net working capital in each period, which is a cash flow adjustment in the cash flow statement: - An increase in net working capital is a cash outflow (cash is being absorbed into receivables or inventory) - A decrease in net working capital is a cash inflow (cash is being released from payables or receivables)
Quality of Earnings
Quality of earnings (QoE) analysis is the central financial due diligence deliverable — a detailed reconciliation from a target's reported EBITDA to a normalized figure, removing one-off items, non-recurring items, and non-operational items to arrive at a figure that more reliably represents sustainable, ongoing earnings. Because the resulting normalized EBITDA is typically the earnings base a transaction's valuation multiple is applied to, an unsupported or aggressive quality of earnings adjustment has a direct, dollar-for-dollar effect on the price paid.
