Share purchase agreements and price mechanisms: what to do in the first ten days depends on which mechanism is running. Once completion accounts are delivered or a leakage claim is raised, the priority is to confirm the trigger date, preserve the underlying financial data, and calendar the contractual deadline before anything is amended or explained away.
Who this concerns
This is relevant the moment a Swedish share purchase agreement built around a locked box or a completion accounts mechanism moves from signing towards the point where money actually changes hands. It concerns both sides: the seller who has to defend a leakage claim or a set of draft accounts, and the buyer who has to substantiate one.
It applies whether the counterparty is a trade buyer, a private equity vehicle, or a founder staying on under an earn-out. The people who end up carrying the ten-day window are usually finance staff and general counsel rather than the negotiators who agreed the clause in the first place, and by the time it lands on their desk the drafting choices made months earlier are already fixed. For the underlying documentation and how these mechanisms are usually structured in a Swedish share deal, the contracts and transactions practice hub sets out the wider picture.
The first ten days matter disproportionately because many financing arrangements and escrow releases are tied to the same milestone. A buyer's lender may condition drawdown on the completion accounts being final and undisputed, and a seller waiting on an escrow release has no practical route to that money until the ten-day window closes without objection or the objection itself is resolved.
It does not concern parties to an asset deal in the same way: transfer of individual assets and liabilities runs on a different logic, and the completion accounts concept does not translate directly.
What the law says
There is no statutory objection period for a price adjustment under a Swedish share purchase agreement. Swedish contract law rests on freedom of contract, avtalsfrihet, and a price mechanism clause is treated the same way as any other commercially negotiated term: it runs as drafted, without an implied grace period and without a court reading in extra time because ten days felt short in hindsight.
What general contract law does contribute is the framework for interpreting what the clause actually means when the wording is ambiguous, and for assessing whether one side behaved in a way that estops it from relying on a deadline it helped create. Under Swedish law as it currently stands, a party that stays silent for the full ten days and then claims it never received proper notice will usually still have to explain why it did not raise the point at the time.
The clause also sits within a wider document. Most Swedish share purchase agreements confirm that in the event of any conflict, the SPA itself takes precedence over the disclosure letter or side letters exchanged during negotiation, and the ten-day mechanism should be read against the main agreement first, with ancillary documents used only to interpret ambiguous terms rather than to override the clock itself.
None of this changes the basic point: the clock, the recipients, and the form of notice are whatever the signed agreement says they are. The first job in the first ten days is reading that clause again, not researching the general law around it.
How it works in practice
Day one: confirm what actually started the clock
The ten-day period does not usually start on the date of signing. It starts on delivery of the draft completion accounts, on the effective date under a locked box structure, or on service of a leakage notice, depending on which mechanism the agreement uses. Confirm which event triggered the clock and get the delivery date in writing from whoever sent it, because a dispute about the start date is far more common than a dispute about the substance of the accounts themselves.
Days one to three: secure the underlying data before it moves
Management accounts, working capital schedules and general ledger extracts have a habit of being revised, reclassified or simply overwritten in the ordinary course of business during exactly the period when they matter most. Pull a fixed copy of everything the completion accounts or leakage claim relies on, and record who had access to the underlying systems and when.
Locked box and completion accounts run on different clocks
A locked box price is fixed at signing, subject to permitted leakage between signing and completion. The dispute, if there is one, is about whether a payment was permitted leakage or not, and it typically runs from the date the leakage schedule is delivered. A completion accounts mechanism works the other way round: the price adjusts after completion once the actual accounts are drawn up, and the ten-day period usually runs from delivery of the draft accounts rather than from completion itself. Treating the two as interchangeable is the single most common source of a missed deadline.
Leakage claims sit on their own timetable
If the mechanism is locked box, a leakage claim is not the same event as a price adjustment claim, and the agreement will usually set a separate notice period for each. Check whether the leakage clause requires a specific form of notice, whether it distinguishes permitted from non-permitted leakage by category, and whether interest or a multiplier applies to a successful claim.
If the agreement provides for an independent expert
Many Swedish share purchase agreements route an unresolved dispute over the completion accounts to an independent expert rather than to court or arbitration. If that clause exists, the ten-day window is usually the period for raising an objection before the right to refer the matter to the expert is triggered, not the period for resolving the dispute itself. Missing it can convert a genuine accounting disagreement into accounts that are deemed final by the operation of the clause.
Escrow and holdback mechanics tied to the same clock
Where part of the price sits in escrow pending resolution of the price adjustment, the escrow agent will usually require written confirmation from both parties, or a determination under the expert clause, before releasing funds. Missing the ten-day window does not just risk losing the substantive argument, it can also delay release of an escrow balance that has nothing to do with the disputed amount, because most escrow instructions are drafted to require a joint instruction rather than a unilateral one.
Notices: form, address, and who has to receive them
A notice sent to the wrong address, in the wrong format, or to the wrong recipient inside a counterparty's organisation can be treated as no notice at all under the clause as drafted. Check the notices provision specifically for this deal, not a template from a previous one: the required form of delivery, the addresses on file, and whether a copy also has to go to legal counsel or an escrow agent.
What to check in the first ten days
- The exact event that started the clock, in writing
- Whether the mechanism is locked box, completion accounts, or both
- The form, recipient and address required by the notices clause
- Whether an independent expert clause exists and what it requires before referral
- Whether the underlying financial data has been preserved in its original form
- Whether any board members are still bound by warranties despite ansvarsfrihet at the last general meeting
- Whether the deadline falls on a business day and how the agreement treats weekends and public holidays
Does a pending product design or copying dispute affect how the price adjustment is calculated?
Only if the completion accounts or the warranties specifically bring intellectual property exposure into the price calculation, which is common where the target's value sits substantially in its product range. Where that link exists, a live design dispute can feed directly into a working capital or contingent liability line. The mechanics of how a design dispute runs and what its own deadlines look like are set out separately in the design protection deadline overview.
Can the parties extend the ten-day period once it has started running?
Usually yes, but only if both sides agree in writing and the agreement itself does not expressly prohibit an extension. An informal exchange of emails is rarely enough on its own if the notices clause requires a specific form; the safer course is a short written variation that references the original clause and states the new date.
Does a seller's ansvarsfrihet at the last general meeting protect against a later price adjustment claim?
No. Ansvarsfrihet, the discharge from liability that shareholders vote on at the annual general meeting when approving the previous year's accounts, releases board members from liability towards the company for that financial year. It has no bearing on a price adjustment or leakage claim brought by a buyer under the share purchase agreement, which is a separate, contractual claim running between buyer and seller rather than between the company and its board. What that discharge does and does not cover is set out in more detail in what ansvarsfrihet actually covers.
The numbers
There is no fixed statutory figure that governs this. Ten days is a common convention in Swedish market practice for the objection window on completion accounts, but it is a drafting choice, not a legal minimum, and some agreements run longer or shorter windows for the same event. The only number that matters in a given deal is the one written into the signed agreement, and it should be read from that document rather than assumed from what is typical elsewhere.
What does vary, and what drives how much work and cost sits inside the ten days, is the complexity of the underlying accounts, the number of line items in dispute, whether the leakage schedule covers a handful of payments or a full trading period, and whether an independent expert has to be engaged. A single disputed working capital adjustment on otherwise clean accounts is a different piece of work from a leakage claim spanning multiple group entities and several currencies.
Cost in this ten-day window is driven far more by the state of the underlying records than by the sums in dispute. A well-kept set of management accounts with a single disputed line item can be resolved by an accountant in a matter of hours; a leakage claim spanning several subsidiaries with inconsistent bookkeeping can require a forensic exercise before either side can even state its position with confidence.
Where it usually goes wrong
The most common failure is not missing the deadline outright but treating the wrong event as its starting point, so that a party believes it still has time when the window has already closed. The second is assuming that because the underlying dispute is substantial, a court will overlook a procedural lapse in how the objection was raised; Swedish courts and arbitral tribunals generally do not rewrite a commercially negotiated notice clause to rescue a party that missed it.
A further recurring issue is treating calendar days and business days as interchangeable when the clause specifies one and the sender assumes the other, particularly around the Swedish midsummer and Christmas periods when several business days can fall consecutively. Where the underlying documents are not in Swedish, a further practical point is whether the notices clause requires delivery in a specific language, since a notice served only in English against a clause silent on language is usually still valid but frequently disputed on that basis alone.
The position also changes when the transaction has a foreign element. Where the buyer, the seller, or the target's parent sits outside Sweden, the notices clause needs to be read against whatever method of service and time-zone convention it specifies, because a notice validly sent from London or Frankfurt can still arrive, for delivery purposes, on a different Swedish business day than intended. Where the acquiring vehicle is itself a joint venture involving a Swedish partner, questions of who inside that structure has authority to receive or waive a notice can raise separate governance issues, covered in more detail in the context of joint ventures with a Swedish partner. Governing law and forum choices in a cross-border agreement also affect where a dispute over the ten-day window would actually be argued, a subject addressed on its own terms in the material on governing law and dispute clauses.
The boundary also runs the other way: where the transaction was structured as an asset purchase rather than a share purchase, the completion accounts concept as described here does not apply in the same form, and the relevant undertakings sit closer to what is described in the material on asset deal transfer undertakings.
What to do next
The work that can be done without outside advice is largely fact-gathering: fixing the trigger date, preserving the data, and reading the notices clause against what was actually sent. Where this stops being a filing exercise is the point where the figures themselves are disputed, where an independent expert referral becomes a live possibility, or where the counterparty is arguing that no valid notice was given at all. That is a document-specific assessment rather than a general one, and it is where a structured assessment call is the next step rather than a further round of internal review.
