The arrangement between an inventory secured party and its debtor typically requires the secured party to make periodic advances against incoming inventory or periodic releases of old inventory as new inventory is received. A fraudulent debtor may apply to the secured party for advances even though it has already given a purchase-money security interest in the inventory to another secured party. For this reason, subsections (b)(2) through (4) and (c) [Maine cite subsection (2), paragraphs (b) to (d) and subsection (3)] impose a second condition for the purchase-money security interest's achieving priority: the purchase-money secured party must give notification to the holder of a conflicting security interest who filed against the same item or type of inventory before the purchase-money secured party filed or its security interest became perfected temporarily under Section 9-312(e) or (f) [Maine cite section 9-1312, subsection (5) or (6)]. The notification requirement protects the non- purchase-money inventory secured party in such a situation: if the inventory secured party has received notification, it presumably will not make an advance; if it has not received notification (or if the other security interest does not qualify as purchase-money), any advance the inventory secured party may make ordinarily will have priority under Section 9-322 [Maine cite section 9-1322]. Inasmuch as an arrangement for periodic advances against incoming goods is unusual outside the inventory field, subsection (a) [Maine cite subsection (1)] does not contain a notification requirement.

5. Notification to Conflicting Inventory Secured Party: Timing. Under subsection (b)(3) [Maine cite subsection (2), paragraph (c)] , the perfected purchase-money security interest achieves priority over a conflicting security interest only if the holder of the conflicting security interest receives a notification within five years before the debtor receives possession of the purchase-money collateral. If the debtor never receives possession, the five-year period never begins, and the purchase-money security interest has priority, even if notification is not given. However, where the purchase-money inventory financing began by the purchase-money secured party's possession of a negotiable document of title, to retain priority
