KANSAS COMMENT, 1996

1. Subsection (1) outlines the effect of a course of performance by the parties under their contract. For conduct to constitute a course of performance, the contract must involve repeated occasions for performance by a party. A single instance of conduct does not constitute a course of performance. See Official Comment 4 to this section. The other party must have knowledge of the nature of the performance and the opportunity to object, yet nevertheless accept or acquiesce without timely objection. If the other party objects to the conduct, there is no course of performance.

2. A course of performance can serve a number of purposes. Under subsection (1), a course of performance is relevant in interpreting the parties' agreement. Under 84-2-202(a), a course of performance may supplement the parties' agreement by supplying a missing term. Under subsection (3), it may show waiver or modification of the contract terms. This provision is important given subsection (2), which provides that express terms control a conflicting course of performance. Thus, even if the express term and the course of performance cannot be construed as consistent with each other, the course of performance may nonetheless be a waiver or modification.

3. Subsection (2) also incorporates course of performance into the hierarchy set out in 84-1-205(4). It makes clear that a course of performance controls over a course of dealing and a usage of trade. This ranking makes sense, since the parties' course of performance under this contract, if available, presumably is a better indication of their intent than a course of dealing under another contract or a usage of trade.

4. Unlike course of dealing and usage of trade, which apply throughout the Code (see 84-1-205), course of performance under this section applies only to contracts for the sale of goods under Article 2. Nevertheless, Kansas courts apply a similar concept under other articles of the Code. See, e.g., North Central Kansas Prod. Credit Ass'n v. Washington Sales Co., 223 K. 689, 577 P.2d 35 (1978) ("course of conduct" under Article 9); see also 1996 Kansas Comment 7 to 84-1-205.
