Balance Sheet Warranties in M&A: Risk and Drafting.

The balance sheet warranty – more precisely, the annual financial statements warranty – is one of the economically most significant warranties in a share purchase agreement (SPA) and one of the most dispute-prone. For years, W&I claims studies have shown that breaches in the area of financial statements/accounts are among the recurring claim categories with particularly high loss potential. That is hardly surprising. Buyers regularly rely on the annual financial statements as a central basis for valuation, and the balance sheet warranty is meant to protect their confidence in that basis.

This article explains the different forms a balance sheet warranty can take, why the wording can determine substantial liability risk and which practical drafting problems arise most often.

Key Takeaways

• A balance sheet warranty usually concerns the full reference financial statements, not only the balance sheet in the narrow sense.
• A hard balance sheet warranty shifts even objectively unknown risks more strongly to the seller; a soft warranty stays closer to the accounting-law error and knowledge standard.
• For unaudited financial statements, the warranty should match the actual level of preparation or review.
• The method of calculating damages should be considered when drafting the clause: balance sheet top-up and purchase-price-based damages can diverge materially.
• The balance sheet warranty, purchase price mechanism, specific warranties and W&I insurance need to be considered together.

Two-part structure

Balance sheet warranties typically follow the wording of § 264 para. 2 sentence 1 HGB and often have a two-part structure:

1. Preparation principles: The annual financial statements were prepared with the diligence of a prudent merchant, in accordance with statutory requirements, German generally accepted accounting principles (GoB) and with due regard to accounting and valuation consistency.
2. Substantive accuracy: The annual financial statements give a true and fair view of the company’s assets, financial position and earnings position.

This two-part structure is common in practice. The decisive question, however, is not whether both elements are included, but what standard is meant to apply to substantive accuracy.

“Hard” and “soft” balance sheet warranties

Accounting requires valuations, assessments and forecasts, for example as to the recoverability of receivables, the level of provisions for uncertain liabilities or the useful life of fixed assets. Under the accounting concept of error, annual financial statements are not incorrect merely because the actual facts later turn out differently. What matters is whether there was an objective breach of accounting rules, including German GAAP (GoB), and whether a prudent merchant could have identified that breach at the time of preparation through a diligent and conscientious review. This normative-subjective standard underlies German accounting law.

The parties may deviate from this in the SPA. That sounds like a detail. It is not. They may agree that the seller is not only responsible for proper preparation under accounting standards, but also for the objective correctness of the annual financial statements. Whether such a broader standard is intended is a matter of contractual interpretation under §§ 133, 157 BGB – and it is the core of the debate about hard and soft balance sheet warranties.

Soft, subjective balance sheet warranty

A soft balance sheet warranty is breached if there was an objective breach of the applicable accounting rules, including GoB, and that breach would have been recognisable to a prudent merchant at the time of preparation upon a diligent review. What matters is therefore not whether the persons involved actually knew of the relevant circumstance. Risks that were in fact unknown but would have been recognisable upon proper preparation remain covered by the warranty. The buyer generally bears only those risks that would not have been recognisable even applying the required merchant’s diligence, or that did not have to be recognised under the accounting rules.

Hard, objective balance sheet warranty

A hard balance sheet warranty goes further. It warrants the objective correctness of the annual financial statements. The seller then also assumes liability for risks that were neither known nor recognisable at the time the balance sheet was prepared and that, under the applicable accounting principles, did not have to be recorded at all. From the seller’s perspective, this is significant. In the extreme case, the seller may be liable for contamination on the factory site that nobody knew about when the balance sheet was prepared, or for an uncollectible receivable that still looked fully recoverable on the balance sheet date.

Intermediate approach, objective-subjective

In practice, a middle course is often chosen: the proper preparation of the annual financial statements is warranted objectively, whereas the “true and fair view” element is limited to the knowledge of certain persons – typically the managing directors of the target – at the time of preparation.

In this model, what is warranted objectively is not the economic truth of the financial statements with unlimited hindsight. It is compliance with the agreed preparation principles. The buyer therefore does not have to prove that the seller or management knew of the accounting error or was at fault. The buyer does, however, have to show that the financial statements were objectively not properly prepared under the agreed standard, for example HGB/GoB and accounting consistency.

For example, if the target recognises revenue although the relevant performance had not yet been delivered by the balance sheet date under the agreed accounting principles, or changes its inventory valuation method without a proper basis, the preparation warranty may be breached even if management did not recognise the accounting treatment as incorrect. Lack of knowledge does not relieve the seller, because proper preparation was warranted objectively.

The position is different for an unknown economic risk that did not have to be recognised under proper accounting principles. If a customer unexpectedly defaults months after the financial statements were prepared and there were no prior warning signs, the intermediate approach will usually not be breached. If, however, management knew at the time of preparation that the receivable was specifically at risk and nevertheless booked no impairment, the knowledge-qualified substantive warranty may apply without forcing the seller to assume liability for all unknown business risks.

The case law: OLG Munich and OLG Frankfurt

Published court decisions on balance sheet warranties are rare because share purchase agreements usually contain arbitration clauses. That makes two appellate decisions particularly influential in the discussion.

OLG Munich, judgment of 30 March 2011, 7 U 4226/10

The case concerned a balance sheet warranty stating that the annual financial statements had been prepared in compliance with GoB and accounting and valuation consistency and gave a true and fair view. In fact, receivables that no longer existed had been recognised as assets. The Higher Regional Court of Munich interpreted the clause as a warranty of objective correctness and, in substance, granted the buyer what is often called a balance sheet top-up, i.e. compensation in the amount of the shortfall.

OLG Frankfurt, judgment of 7 May 2015, 26 U 35/12

Here too, the court had to assess a broadly standardised clause. The published decision summarises the clause rather than reproducing its full wording; according to the wording preserved from the first-instance proceedings, however, it contained both the preparation standard of the diligence of a prudent merchant and the statement that the financial statements gave a true and fair view. The Higher Regional Court of Frankfurt nevertheless treated this combination as a hard balance sheet warranty and assumed that the seller was also liable for unknown debts and contingent liabilities. As to legal consequences, however, the court rejected the balance sheet top-up approach and instead focused on the amount by which the buyer had overpaid for the shares in reliance on the correctness of the balance sheet.

Criticism

Both decisions have been criticised in the literature for good reason. The central counterargument is simple: if the clause essentially paraphrases § 264 para. 2 sentence 1 HGB, there is a strong case for also applying the normative-subjective concept of error underlying that provision. It is therefore only partly convincing to derive liability for objectively unknown risks merely from a repetition of the statutory wording. There is also a structural argument. Accounting law does not reflect economic reality by reference to a general truth standard, but within a framework of normative recognition and valuation rules. For that reason, there is often no single economically “correct” balance sheet. That is precisely why it is risky for sellers to adopt standard wording without reflection.

Balance sheet date, subsequent information and knowledge qualification

Balance sheet date reference

The balance sheet warranty should expressly refer to the balance sheet date. That follows, as a starting point, from accounting law anyway, but it should be stated clearly in the SPA. Without an express balance sheet date reference, there is a risk that value-creating circumstances arising only after the balance sheet date are nevertheless read into the warranty. That would undermine the balance sheet date principle.

Subsequent information period

The period between the balance sheet date, preparation of the annual financial statements and signing is of particular practical importance. Facts that become known only after the balance sheet date but objectively already existed on that date may still need to be taken into account, provided they become known before the annual financial statements are finalised. If they become known only later, they will generally not retrospectively make the financial statements incorrect as a matter of accounting law. That is precisely why older reference financial statements create a growing risk that a hard balance sheet warranty becomes, in economic terms, a catch-all liability regime for unknown legacy issues. Imagine the following: the last audited annual financial statements are 14 months old, signing is imminent and the seller is expected to give a hard balance sheet warranty. In those 14 months, receivables may have defaulted, provisions may have become insufficient or legacy liabilities may have surfaced which nobody knew about when the financial statements were prepared.

Knowledge qualification

Merely making the warranty subjective by reference to the “seller’s knowledge” is often too imprecise. Without a clear temporal reference, there is a risk that the focus shifts to knowledge at the time the contract is signed. It is more precise to refer to the knowledge of the corporate body responsible for preparing the financial statements at the time of preparation. This brings the knowledge standard closer to the logic of accounting law. From the buyer’s perspective, there remains a gap, because insights gained between preparation and signing are not automatically covered by the balance sheet warranty. In practice, however, this problem is usually addressed through specific individual warranties rather than by overstretching the balance sheet warranty.

Unaudited financial statements

A frequently underestimated problem is the use of classic balance sheet warranty wording for unaudited financial statements. Many standard clauses implicitly assume that the statements come with an unqualified audit opinion. In practice, however, that is precisely not the case for a large proportion of German companies. Instead, quality may range from a mere compilation based on documents provided, without plausibility checks, to more extensive forms of external review or assessment.

From the seller’s perspective, it is therefore risky to give an unrestricted true-and-fair-view warranty for unaudited financial statements. If there is no audit opinion or comparable external review, the warranty should be drafted as congruently as possible with the actual level of preparation or review. If there is insufficient information to assess the company’s assets, financial position and earnings position with sufficient certainty, there is a strong case for dispensing with broad substantive elements, or at least clearly qualifying them.

For larger sale processes, a voluntary audit of the latest annual or interim financial statements can be a sensible preparatory step. It not only makes due diligence easier, but also tends to improve insurability under W&I. Conversely, W&I insurers will often decline to cover – or cover only in a limited way – an overreaching true-and-fair-view warranty where the financial statements are unaudited.

Calculating damages for breach of warranty

Calculating damages for breach of a balance sheet warranty is one of the least clearly regulated and, at the same time, one of the most dispute-prone issues. At its core, two basic models can be distinguished:

Method	Approach	Advantage	Disadvantage
Balance sheet top-up	Compensation for the shortfall in the affected balance sheet line item	Arithmetically simple, often manageable in litigation	Risk of over- or under-compensation, because the accounting error does not necessarily correspond to the economic loss
Purchase price / value-based calculation	Compensation for the amount by which the buyer overpaid for the shares in reliance on the correctness of the annual financial statements	Closer to the economic loss, especially where valuation-relevant items are concerned	Requires a hypothetical purchase price or enterprise value analysis and is therefore often significantly more dispute-prone

The difference is substantial in practice. If an error in the annual financial statements affects the earnings base relevant to the purchase price, its economic impact may materially exceed the mere accounting shortfall. Conversely, a schematic balance sheet top-up leads to over-compensation if the risk never materialises economically or played no role in pricing. The case law illustrates this range: OLG Munich tended towards the balance sheet top-up approach, while OLG Frankfurt preferred a purchase-price-based damages analysis.

In contractual reality, the method of calculation is rarely specified expressly. Instead, the parties often steer the outcome indirectly, for example through remedy clauses, through exclusion of certain categories of damages or through provisions addressing valuation multiples. That is precisely why the issue of damages should not be left silently to a future dispute.

Interaction with other warranties and mechanisms

Balance sheet warranty and purchase price mechanism

In a closing-accounts structure, the balance sheet warranty and the purchase price adjustment may overlap. The same accounting error can then trigger both a warranty claim and a claim under the purchase price adjustment mechanism. In well-balanced SPAs, this double track is therefore usually resolved through delineation rules. The balance sheet warranty is of particular practical importance in locked-box structures, because there is no subsequent adjustment through closing accounts. Our equity bridge calculator shows how those balance-sheet items affect the path from enterprise value to equity value.

Balance sheet warranty and specific warranties

A balance sheet warranty is no substitute for a differentiated warranty package. Anyone accepting a hard balance sheet warranty effectively takes on catch-all liability for a broad range of balance-sheetable risks. That creates overlaps with specific warranties on litigation, taxes, environment, employment or compliance. Specific warranties with their own knowledge qualifications, materiality thresholds and liability caps generally allow for much more precise risk allocation.

Balance sheet warranty and undisclosed liabilities

An undisclosed liabilities warranty needs to be distinguished from the balance sheet warranty. The balance sheet warranty primarily asks whether the reference financial statements were properly prepared under the agreed standard and, depending on the wording, what picture they give of the company’s assets, financial position and results. An undisclosed-liabilities clause, by contrast, typically focuses on liabilities that were neither shown in the accounts nor otherwise disclosed to the buyer.

Whether an SPA should contain such an additional warranty is not an automatic consequence of the balance sheet warranty; it is a question of risk allocation. From the buyer’s perspective, it may close a gap where certain liability risks are not reliably covered by the annual accounts or by specific warranties. From the seller’s perspective, however, it can quickly become a broad catch-all liability, especially if it is not limited to liabilities required to be recognised or disclosed in the accounts, known circumstances, materiality thresholds or disclosed matters.

The key issue is therefore delineation. Does the clause cover only liabilities that should have been recognised or disclosed in the reference financial statements under the relevant accounting rules? Or does it also capture other obligations, contingent liabilities, litigation, tax risks and operational risks that should really be dealt with in specific warranties? Without clear alignment with the balance sheet warranty, specific warranties, knowledge qualifiers, liability caps and no-double-recovery provisions, the clause creates exactly the uncertainty it is meant to avoid.

Balance sheet warranty and W&I insurance

In W&I-insured transactions, breaches in the area of financial statements/accounts have for years been one of the major drivers of loss. Two drafting consequences follow. First, insurers scrutinise the precise wording of the balance sheet warranty very closely. Second, hard balance sheet warranties and unaudited financial statements regularly create coverage issues, retention issues or premium risk.

What matters in the wording

The differences between warranty types often lie in only a few, but decisive, drafting choices:

• Hard balance sheet warranty: The annual financial statements are described as objectively correct, often with the express clarification that lack of recognisability does not relieve the seller.
• Soft balance sheet warranty: Both proper preparation and substantive accuracy are linked to a knowledge standard, ideally tied to the time of preparation.
• Intermediate approach: The preparation principles are warranted objectively, while substantive accuracy is limited to the knowledge of the managing directors who prepared the statements at the time of preparation; often supplemented by an express clarification that no hard or objective balance sheet warranty is intended.

Common mistakes

1. Adopting standard wording without reflection. A mere paraphrase of § 264 para. 2 sentence 1 HGB may be interpreted more broadly under the appellate case law than the seller expects. If the seller intends to give only a soft warranty, that must be stated expressly.

2. No clear balance sheet date or temporal reference. Without an express link to the balance sheet date, there is room for interpretation against the intended risk allocation. Likewise, merely making the warranty subjective by reference to the “seller’s knowledge”, without a clear temporal reference, is often too vague; the decisive issue is whether knowledge at signing or knowledge when the annual financial statements were prepared is meant to apply.

3. Ignoring the damages side. Anyone drafting the warranty should simultaneously keep the remedies side in mind, in particular whether multiplier effects or later revaluations of the business should be excluded or limited.

4. Unrestricted substantive warranty for unaudited financial statements. That is often neither insurable nor appropriate. For unaudited financial statements, the warranty should be aligned with the actual level of preparation or review, unless the particular facts of the case justify a broad allocation to the seller of risks arising from past circumstances.

The balance sheet warranty is therefore far more than a standard clause. Anyone who does not tailor it precisely in the SPA to the transaction at hand risks lengthy disputes over interpretation and, in the worst case, liability on a substantial scale that neither side truly anticipated when the contract was signed.
