A purchase money security interest (PMSI) under the Uniform Commercial Code (UCC) provides for an exception to the general "first in time, first in priority" financing statement filing structure for perfecting a security interest, since a PMSI will have priority over previously perfected security interests in the same collateral. See UCC Section 9-324. Specifically, Section 9-324 provides that a PMSI in goods has priority over a conflicting prior perfected security interest in the same goods so long as the lender complies with the UCC's rules for filing, timing and notice (for inventory financing).
