Representations and Warranties in Japanese M&A: How They Work in a Share Purchase Agreement Governed by Japanese Law

Key Takeaways

  • ✓A representation and warranty is the seller's promise to the buyer that stated facts about the target company (finances, liabilities, contracts, employees, licences and so on) are true and accurate as of a given time. Neither the Civil Code nor the Companies Act contains a provision on representations and warranties as such
  • ✓Parties may freely determine the content of a contract within the limits of the law (Civil Code, Article 521(2)). What the buyer can claim for a breach therefore depends on how the indemnity clause is drafted
  • ✓Without a clear indemnity clause, disputes tend to turn on whether a claim lies for damages for non-performance (Articles 415 and 416) or for non-conformity under the sale provisions (Articles 562 to 564)
  • ✓Even where a seller has agreed not to be liable for non-conformity in a sale, it cannot escape that liability for facts it knew of but did not disclose (Article 572). A declaration of intention induced by fraud may be rescinded (Article 96)
  • ✓The cap, threshold, claim period, knowledge qualifiers, disclosure schedule and the effect of the buyer's own knowledge should all be set out expressly
  • ✓Parties may choose the governing law (Act on General Rules for Application of Laws, Article 7). Using an English or US-style template under Japanese law can produce unexpected results, for example on the scope of recoverable loss (Civil Code, Article 416)

In a share purchase agreement, a representation and warranty is a clause in which the seller promises that stated facts about the target company are true and accurate. Japan's Civil Code and Companies Act contain no provision on representations and warranties as such, so what a buyer can claim when one turns out to be untrue depends almost entirely on how the contract is drafted.

If the indemnity clause is vague, disputes arise over whether a claim lies under the Civil Code rules on non-performance or non-conformity. For buyers and sellers alike, setting the cap, threshold, claim period and disclosure schedule clearly is the most direct way to avoid post-closing disputes.

When this becomes an issue

  • After the acquisition, unpaid overtime or a tax reassessment at the target comes to light and you want to claim against the seller.
  • Your head office wants to use its standard English-language SPA template for a deal governed by Japanese law.
  • As seller, you are worried about being asked to indemnify matters you already disclosed in due diligence.
  • The buyer knew of a problem from due diligence but claims a breach of warranty after closing.

Representations, covenants and indemnities

A share purchase agreement contains several clauses with related functions. Separating their roles makes the negotiating points easier to see.

ClauseWhat it promisesTypical consequence of breach
Representations and warrantiesThat facts about the target or the seller are true and accurate as of a given timeIndemnification under the indemnity clause; before closing, the buyer need not close (condition not satisfied)
CovenantsThat a party will or will not do something between signing and closing, or after closingClaim for performance, damages, indemnification
IndemnificationThe scope, duration and maximum amount of compensation for loss caused by breach of a representation or covenantThe clause that decides the "exit" for representations and covenants
Specific indemnityCompensation for a particular issue found in due diligence, separately from the warrantiesLets the buyer recover even for a problem it knew about

The Japanese law position: the contract decides

No statutory rule, so drafting is everything

Parties may freely determine the content of a contract within the limits of the law (Civil Code, Article 521(2)). Representations, warranties and indemnities are agreements that rest on this freedom of contract.

What counts as a breach, and what must be paid for it, is therefore determined by the wording of the contract rather than by statute. Importing English or US drafting conventions wholesale leaves open how a Japanese court will read that wording under Japanese law.

Without an indemnity clause, what is the basis for a claim?

Where there is no indemnity clause, or it does not cover the point, the buyer must build its claim on the general rules of the Civil Code.

BasisRuleTypical point of dispute
Damages for non-performance (Article 415)Where an obligor fails to perform in accordance with the purpose of the obligation, the obligee may claim damagesWhether "the facts are true" is an obligation at all; the seller's defence that the failure is not attributable to it (proviso to Article 415(1))
Liability for non-conformity (Articles 562 to 564)Where the delivered subject matter does not conform to the contract in kind, quality or quantity: cure, price reduction, damages or cancellationWhether a problem in the target's business is a non-conformity of the shares sold
Rescission for mistake (Article 95)A declaration may be rescinded where, among other things, the party's understanding of circumstances on which it based the transaction was untrue, it had been indicated that those circumstances formed the basis of the transaction, and the mistake was materialRescission unwinds the whole contract, which is often unrealistic in M&A
Rescission for fraud (Article 96)A declaration induced by fraud may be rescindedThe party seeking rescission must show that the seller committed fraud

Important

The indemnity clause exists to avoid these disputes. If the contract states that the seller will compensate the buyer for loss caused by a breach of warranty, and specifies the scope, cap and period, there is much less need to argue each Civil Code requirement.

Scope of loss: differences from English and US templates

Damages for non-performance are, in principle, for the loss that would ordinarily arise (Civil Code, Article 416(1)). Loss arising from special circumstances may be claimed where the parties should have foreseen those circumstances (Article 416(2)).

The common template exclusion of "consequential damages" does not necessarily map onto Japan's distinction between ordinary and special loss under Article 416. In a contract governed by Japanese law, it is safer to list the heads of loss that are covered, such as lost profits, loss suffered by the target company and legal fees.

Parties may also agree in advance on the amount of damages for non-performance (Article 420(1)). A penalty is presumed to be such a liquidated damages amount (Article 420(3)).

Facts the seller knew but did not disclose

In a sale, even where the seller has agreed not to be liable for non-conformity (Civil Code, Article 562(1), main text) and similar warranty liability, it cannot escape that liability for facts it knew of but did not disclose (Article 572).

The statute does not make clear whether this rule reaches a "sole and exclusive remedy" clause or a cap in a share purchase agreement. Even so, where the seller knowingly concealed a problem, the principle behind this rule and rescission for fraud (Article 96) can become points of dispute.

Caution

As seller, it is risky to withhold a significant issue you know about simply because due diligence did not ask. Contracts commonly provide that matters set out in the disclosure schedule are exceptions to the warranties. Holding back can expose you to liability that the cap and claim period do not protect against.

What the indemnity clause should settle

Main negotiating points

Indemnity negotiations work through the following items. Amounts and periods are negotiated deal by deal; there is no fixed market standard.

ItemWhat it decidesBuyer's interestSeller's interest
CapMaximum total indemnityHigher, or certain warranties carved out of the capLower, a portion of the price
Basket / de minimisNo claim until a threshold is exceeded; small claims not countedLowerHigher
Survival (claim period)How long after closing claims may be madeLonger, especially for tax and employmentShorter
Knowledge qualifierWhether limited to "to the seller's knowledge", and whose knowledgeNo qualifier, or a broad groupQualified
Materiality qualifierWhether limited to "in all material respects"No qualifierQualified
Disclosure scheduleMatters disclosed as exceptions to the warrantiesSpecific; avoid catch-all wordingBroad, including general disclosure
Buyer's knowledge (sandbagging)Whether the buyer may claim for a breach it knew ofExpressly yesExpressly no

Key point

Japanese statute says nothing about the effect of the buyer's own knowledge, so the point is easily disputed unless the contract addresses it. Issues found in due diligence are more reliably dealt with through a specific indemnity or a price adjustment than through the general warranties.

Claim periods and limitation

If the contract sets no claim period, a claim is extinguished by prescription if not exercised within five years from when the creditor knew it could exercise the right, or ten years from when it could be exercised (Civil Code, Article 166(1)).

For non-conformity in kind or quality in a sale, the buyer loses its remedies unless it notifies the seller within one year of learning of the non-conformity (Article 566, main text). This does not apply where the seller knew of the non-conformity at delivery or was unaware of it through gross negligence (proviso). Setting the claim period and the notice procedure in the indemnity clause reduces argument over which rule applies.

How representations and warranties play out, from signing to after closing

  1. 1

    Due diligence

    Review finance, tax, employment, contracts, licences and litigation to identify issues

  2. 2

    Negotiate the scope

    Agree what the seller represents, any knowledge or materiality qualifiers, and the reference times (signing and closing)

  3. 3

    Prepare the disclosure schedule

    The seller sets out specific exceptions to the warranties

  4. 4

    Confirm at closing

    Check, through conditions precedent or a closing certificate, that the warranties remain true and accurate at closing

  5. 5

    Notify any breach

    Follow the notice procedure and deadline in the indemnity clause, stating the basis and estimated amount in writing

Cross-border deals: governing law

The formation and effect of a juridical act are governed by the law chosen by the parties at the time of the act (Act on General Rules for Application of Laws, Article 7). Absent a choice, they are governed by the law of the place with which the act is most closely connected (Article 8(1)). The parties may later change the governing law, although a change that would harm a third party's rights cannot be asserted against that third party (Article 9).

An overseas buyer acquiring a Japanese company may agree to Japanese governing law. In that case the English-language warranties and indemnities are then interpreted under Japanese law. Where both English and Japanese versions are prepared, decide which prevails.

A foreign investor acquiring shares in a Japanese company may also need to file a prior notification or post-transaction report under the Foreign Exchange and Foreign Trade Act (see our column on inward direct investment).

What you can do now

  • Check whether your SPA template sets out the consequences of a breach of warranty in the indemnity clause.
  • Check how the definition of indemnifiable "loss" relates to ordinary and special loss under Article 416 of the Civil Code.
  • Confirm that the cap, threshold, claim period and notice procedure are stated in figures and steps.
  • List the issues found in due diligence and decide whether each will be handled by a specific indemnity or a price adjustment.
  • As seller, prepare to describe known issues specifically in the disclosure schedule.
  • Decide the governing law and which language version prevails.

When to consult a lawyer

  • Before signing a letter of intent. The direction on warranty scope and the cap may be set at this stage.
  • When an English-language SPA draft arrives from an overseas counterparty.
  • When due diligence uncovers a significant issue and you need to negotiate a price adjustment or specific indemnity.
  • When unpaid liabilities or regulatory action at the target come to light after closing. The notice deadline in the indemnity clause may be approaching.
