Sandbagging in Alberta Business Deals: Who Bears the Risk of a Known Breach?
September 25, 2026
Business purchase agreements often contain detailed representations and warranties about the company or assets being sold. These may address financial statements, contracts, taxes, litigation, employees, regulatory compliance, intellectual property, and ownership of assets.
But what happens when a purchaser learns before closing that one of those representations may be inaccurate, closes the transaction anyway, and later seeks compensation?
This scenario is commonly known as sandbagging. Whether a purchaser can pursue a post-closing claim can depend heavily on the wording of the purchase agreement, including whether it contains a pro-sandbagging clause, an anti-sandbagging clause, or no express provision at all.
What Does “Sandbagging” Mean in an M&A Transaction?
Sandbagging generally occurs when a purchaser learns before closing that a seller’s representation or warranty may be inaccurate but proceeds with the acquisition and later relies on that inaccuracy to seek indemnification or another contractual remedy.
For example, a seller may represent that the corporation has complied with applicable environmental requirements. During due diligence, the purchaser discovers information suggesting otherwise. The purchaser closes the deal and later asserts a claim based on the inaccurate representation.
The central issue is whether the purchaser’s pre-closing knowledge affects its ability to enforce the seller’s contractual promise.
Why Representations and Warranties Matter
Representations and warranties are a core feature of private business acquisitions because they allocate risk between buyers and sellers.
Even extensive due diligence may not reveal every liability, tax issue, regulatory concern, contractual problem, or other risk associated with a business. Representations and warranties provide contractual statements about the condition of the target company or purchased assets.
Purchase agreements often connect those promises to indemnification provisions, allowing a purchaser to pursue certain remedies if a representation proves inaccurate after closing. Sandbagging clauses address what happens when the purchaser already knew about the issue before the deal closed.
What Is a Pro-Sandbagging Clause?
A pro-sandbagging clause generally preserves a purchaser’s contractual remedies even if the purchaser knew before closing that a representation or warranty was inaccurate.
The agreement may state that the purchaser’s investigation or knowledge will not affect its right to indemnification. This allows the parties to treat due diligence and contractual risk allocation as separate concepts.
In practical terms, the seller remains responsible for the promises it made in the agreement, even where the purchaser uncovered contrary information during the transaction process.
How Does an Anti-Sandbagging Clause Work?
An anti-sandbagging clause generally limits a purchaser’s ability to recover for a breach that it knew about before closing. For example, an agreement may provide that the seller will not be liable for losses arising from an inaccurate representation if the purchaser had knowledge of the inaccuracy before completion.
This can make the definition of knowledge particularly important. The agreement may refer only to actual knowledge held by specifically identified executives, or it may adopt a broader standard that includes information that could have been discovered through reasonable inquiry.
The contract may also address whether knowledge held by employees, advisors, consultants, or other members of the transaction team is attributed to the purchaser.
What If the Purchase Agreement Says Nothing?
Some agreements contain neither a pro-sandbagging nor an anti-sandbagging clause. In those situations, the parties may have to rely on the remaining terms of the agreement and the applicable law. Relevant considerations can include the wording of the representation or warranty, the indemnification provisions, the disclosure regime, contractual definitions, and the purchaser’s knowledge.
Expressly addressing sandbagging can reduce uncertainty about whether pre-closing knowledge affects post-closing rights.
Disclosure Schedules Can Be Just as Important
Sandbagging clauses do not operate in isolation. Disclosure schedules can significantly affect whether a representation or warranty has been breached at all. For example, a seller may represent that there is no pending litigation while expressly disclosing an existing lawsuit in the disclosure schedules. That disclosure may qualify the representation and prevent the identified matter from becoming a breach.
Purchase agreements may also specify what constitutes sufficient disclosure. Information buried in a data room may not necessarily be treated the same way as a matter expressly identified in a disclosure schedule. The distinction between purchaser knowledge and seller disclosure can therefore be important.
Sandbagging and the Indemnification Framework
Even where a purchaser retains the right to pursue a known breach, the claim may still be subject to the broader indemnification framework. Private M&A agreements commonly include survival periods, baskets, deductibles, liability caps, exclusions, notice requirements, and procedures for third-party claims.
Known issues may also be addressed through specific indemnities rather than relying on general representations and warranties. In that situation, the parties can expressly allocate responsibility for an identified risk.
Therefore, the effect of a sandbagging provision depends on how it interacts with the rest of the agreement.
Representations and Warranties Insurance Adds Another Layer
Representations and warranties insurance can further complicate the analysis. These policies may cover certain losses arising from breaches of representations and warranties, but known matters are generally treated differently from unknown risks. Purchaser-side policies commonly exclude issues already known before closing.
As a result, a purchaser may have contractual rights against a seller that do not align precisely with the scope of available insurance coverage.
A Small Clause With Significant Consequences
Sandbagging provisions address a fundamental transaction question: does a purchaser lose the benefit of a seller’s contractual promise because it discovered before closing that the promise may be inaccurate?
Pro-sandbagging clauses, anti-sandbagging clauses, and contractual silence can produce different outcomes. Their effect may also depend on knowledge definitions, disclosure schedules, indemnification provisions, due diligence procedures, and insurance coverage.
For parties buying or selling businesses in Alberta, addressing these issues directly in the purchase agreement can provide greater clarity about how known risks will be allocated before and after closing.
