Colorado Code
Part 3 - Perfection and Priority
§ 4-9-335. Accessions

Source: L. 2001: Entire article R&RE, p. 1368, § 1, effective July 1.







Example 1: SP-1 holds a security interest in the debtor's tractors (which are not subject to a certificate-of-title statute), and SP-2 holds a security interest in a particular tractor engine. The engine is installed in a tractor. From the perspective of SP-1, the tractor becomes an "accession" and the engine is the "other goods." From the perspective of SP-2, the engine is the "accession" and the tractor is the "other goods." The completed tractor tractor cum engine constitutes the "whole."
Example 2: Debtor owns a computer subject to a perfected security interest in favor of SP-1. Debtor acquires memory and installs it in the computer. Whether SP-1's security interest attaches to the memory depends on whether the security agreement covers it.
Similarly, this section does not determine whether perfection against collateral that becomes an accession is effective to perfect a security interest in the whole. Other provisions of this Article, including the requirements for indicating the collateral covered by a financing statement, resolve that question.
Example 3: Debtor owns an office computer subject to a security interest in favor of SP-1. Debtor acquires memory and grants a perfected security interest in the memory to SP-2. Debtor installs the memory in the computer, at which time (one assumes) SP-1's security interest attaches to the memory. The first-to-file-or-perfect rule of Section 9-322 governs priority in the memory. If, however, SP-2's security interest is a purchase-money security interest, Section 9-324(a) would afford priority in the memory to SP-2, regardless of which security interest was perfected first.
Example 4: Debtor owns an automobile subject to a security interest in favor of SP-1. The security interest is perfected by notation on the certificate of title. Debtor buys tires subject to a perfected-by-filing purchase-money security interest in favor of SP-2 and mounts the tires on the automobile's wheels. If the security interest in the automobile attaches to the tires, then SP-1 acquires priority over SP-2. The same result would obtain if SP-1's security interest attached to the automobile and was perfected after the tires had been mounted on the wheels.
