Also known as: U.C.C. § 2-609 · UCC 2-609 · § 2-609 · adequate assurance · assurance of performance
Written by attorneys · grounded in primary & secondary sources — see below
A statutory rule in contracts for the sale of goods that imposes on each party an obligation that the other's expectation of receiving due performance will not be impaired. When reasonable grounds for insecurity arise with respect to the performance of either party, the other may in writing demand adequate assurance of due performance and until receipt of such assurance may, if commercially reasonable, suspend any performance for which it has not already received the agreed return. Acceptance of any improper delivery or payment does not prejudice the aggrieved party's right to demand adequate assurance of future performance.

The court held that the merger alone did not constitute repudiation.
Reasonable grounds arise from objective facts such as media reports of regulatory actions that could close a plant, incomplete deliveries, warehouse damage, missed deadlines, layoffs, or a buyer's financial distress signals. These facts must support a belief that the other party will commit a breach giving rise to damages for total breach. Vague rumors alone are insufficient, but cumulative concrete indicators satisfy the standard.

No. Acceptance of any improper delivery or payment does not prejudice the right to demand adequate assurance of future performance. Each demand is evaluated on its own facts, and new concerns about quality or capacity supply fresh grounds even after earlier acceptances.

Adequacy is determined according to commercial standards in the relevant industry. A vague statement of confidence or commitment without concrete plans, timelines, certifications, or financial safeguards is typically inadequate when prior defects or instability have been reported. Detailed production schedules, contingency plans, or third-party guarantees are often required.
