Warranty Claim
Warranty Claim is a deal mechanics term governing the financial and legal specifics of how purchase consideration is structured or adjusted in M&A.
Full Definition
A warranty claim is a formal demand by the buyer against the seller under the representations and warranties provisions of a purchase agreement, asserting that a specific representation or warranty made by the seller was inaccurate or false and that the buyer has suffered losses as a result. Warranty claims are the primary mechanism through which buyers seek post-closing indemnification from sellers for problems discovered after the transaction has closed — essentially holding the seller financially responsible for conditions that existed before closing but were misrepresented or not disclosed.
The process for asserting a warranty claim begins with the buyer identifying a breach — typically discovered during integration, through financial performance that deviates from represented figures, or through third-party claims (a customer suit, a regulatory investigation) that relate to pre-closing events. The buyer then submits a formal notice of claim to the seller (or to the escrow agent if an indemnification escrow is in place), specifying the representation allegedly breached, the facts constituting the breach, and the losses claimed. This notice must typically be provided within the survival period of the relevant representation.
Survival periods determine how long buyers can assert warranty claims. General business representations typically survive for 12-24 months post-closing. Fundamental representations (title to shares, authorization, capitalization) often survive indefinitely or for 5-7 years. Tax representations typically survive until the relevant statute of limitations expires. Any representation that has expired can no longer be the basis for a warranty claim — which creates urgency in identifying potential breaches before the survival clock runs out.
Warranty claims are subject to deductible (basket) and cap provisions. The deductible (sometimes called a "basket") is the minimum threshold of losses that must be exceeded before the seller has any indemnification obligation — commonly 0.5-1.5% of deal value. The indemnification cap limits the seller's total exposure — typically 10-15% of deal value for general representations. These provisions protect sellers from nuisance claims and limit their total post-close financial exposure.
For R&W insurance transactions, warranty claims are submitted to the insurer rather than to the seller directly (or in addition to the seller for amounts above the policy). R&W insurance has become the dominant mechanism for warranty claims in mid-market transactions because it eliminates the adversarial dynamic of buyer vs. seller post-close and provides a solvent counterparty for larger claims.
Seller vs. Buyer Perspective
Your exposure to warranty claims is primarily determined by the quality of your representations and disclosures. Thorough, accurate disclosure schedules are your best defense — if you disclosed an issue in the schedules, it is typically carved out of the representation and cannot be the basis for a claim. Sellers who make sweeping general representations and provide incomplete disclosure schedules are creating significant post-close exposure.
Maintain records of the due diligence process: what information was provided, what questions were asked and answered, and what the buyer confirmed in writing. If a buyer makes a warranty claim post-close, your defense will depend partly on demonstrating that the buyer had access to the relevant information and made their own independent assessment.
For deals with R&W insurance in place, your practical exposure as a seller is dramatically reduced — the insurer bears the economic risk of most warranty claims, and you're only liable for fraud. This is a meaningful benefit that sellers sometimes underweigh when negotiating deal structure: R&W insurance-backed deals can have smaller escrows (or none) and shorter survival periods, significantly reducing the seller's contingent post-close exposure.
Warranty claims must be formally and timely asserted — verbal or informal complaints do not preserve your rights. Assign someone (internal counsel or outside M&A attorneys) to actively monitor for potential warranty claim triggers in the 12-24 months post-closing. The most common claim triggers: customers who cancel contracts that the seller represented as stable, tax liabilities that emerge from pre-closing audit periods, environmental violations that predate the closing, and undisclosed litigation from former employees or customers.
Assess each potential claim against the basket threshold — claims below the deductible provide no recovery. Focus indemnification resources on material breaches where recoverable losses clearly exceed the basket. Small claims drain management attention, strain post-close relationships, and rarely justify the legal cost of asserting them.
For R&W insurance claims, engage insurance coverage counsel who specializes in M&A claims. The claims process under R&W policies has specific documentation requirements, notice obligations, and cooperation standards. Failure to comply with these requirements can result in claim denial even for valid underlying breaches.
Real-World Example
Eight months post-close, a buyer discovers that the acquired business's largest customer (25% of revenue) was already in discussions with a competitor when the seller represented customer relationships as stable and in good standing. The customer terminates its contract in month 9. The buyer submits a warranty claim under the "material contracts" representation, alleging the seller knew the contract was at risk and failed to disclose it. The claim is $1.8M in lost future revenue (net present value of lost contract). The seller's escrow ($500K) is insufficient to cover the claim. The buyer pursues the full claim through arbitration, recovering $900K (split between escrow and direct seller payment) after 14 months of litigation.
Why It Matters & Common Pitfalls
- !Missing the claim deadline. Warranty claims not asserted within the survival period are barred — permanently. Calendar every representation's survival deadline at closing and monitor for potential breaches proactively.
- !Basket threshold underestimation. Individual breaches that each fall below the basket threshold aggregate toward it — but only if the purchase agreement uses a 'tipping basket' (aggregate all losses, then recover all once threshold is met) rather than a 'deductible basket' (recover only losses above the threshold). Understand which basket mechanic applies.
- !Insufficient claim documentation. Warranty claims require specific documentation of the breach, causation, and damages. Claimants who pursue claims without organized documentation face evidentiary challenges in arbitration or litigation.
- !Damage calculation disputes. Even when a breach is clear, quantifying the buyer's losses from that breach is often contested. Engage damages experts early in the claim process and build your damages model from multiple methodologies for credibility.
