The standard price adjustment formula: Equity Value = Enterprise Value − Net Debt + (Actual NWC − NWC Peg). If actual NWC at closing is above the peg, the seller receives a top-up; below the peg, a deduction. Net debt is calculated as agreed in the SPA, which must define each debt-like item and each cash-like item. Deferred consideration (earnout, vendor loan) is added separately.
The most common post-LOI value transfer mechanisms: (1) Working capital manipulation — sellers collect aggressively and pay suppliers slowly in the months before closing, inflating cash and depressing payables. Buyers look for this pattern and deduct it from the peg calculation. (2) Net debt definition scope creep — buyers add items to net debt after LOI (IFRS 16 leases, pension provisions, tax provisions) that were not agreed in the LOI. (3) Earnout metric definition disputes — ambiguity in how EBITDA is measured post-closing creates claim risk. All of these should be fixed in the LOI and documented precisely in the SPA.
Locked-box mechanics avoid closing adjustments entirely by fixing the economic transfer date at a historical balance sheet. The seller receives a 'ticker' (daily interest for the period between the locked-box date and closing) and no adjustment is made at closing. This is cleaner for sellers but requires agreement that the historical accounts accurately reflect the business — making a robust audit and QoE pre-condition for this structure.
Price adjustment waterfall
Enterprise Value: €18m. Net debt at closing: (€2.5m). NWC peg: €1.8m; actual NWC: €1.5m → shortfall: (€0.3m). Cash at closing: €18m − €2.5m − €0.3m = €15.2m. Plus: vendor loan (to be received over 5 years): €3m. Total headline consideration: €18.2m. Seller's day-1 cash: €15.2m.
Frequently asked questions
How is the net debt calculated at closing?
By reference to a set of agreed accounting principles and a defined list of items. In a completion accounts deal: both buyer and seller prepare their own closing accounts, then a process of review, dispute, and independent accountant determination follows. In a locked-box deal: net debt is calculated at the locked-box date from audited accounts and agreed in the LOI. Sellers should push for locked-box wherever their balance sheet is clean and predictable.
What is the typical timeline for post-closing price adjustments?
Completion accounts: buyer typically delivers draft accounts within 30–60 days post-closing; seller has 20–30 days to object; disputes go to an independent accountant who determines the matter in 30–60 days. Total: 3–6 months from closing to final equity value determination. For significant escrow amounts, this can leave the seller in uncertainty for extended periods — another reason to negotiate tight definitions in the LOI.
Can price adjustments be limited contractually?
Yes — a common negotiation point is the 'accounting buffer' (or 'materiality threshold') for price adjustments: adjustments below a defined amount (say €100k) are ignored to avoid disputes over small differences. Some deals also set a 'collar' — the adjustment can only increase or decrease the equity value by a defined maximum, preventing extreme outcomes from unexpected NWC movements.
