N.D. Cent. Code § 41-09-42

(17) Proceeds of Non-Filing Collateral: Non-Temporal Priority. Subsection (c)(2) provides a baseline priority rule for proceeds of non-filing collateral which applies if the secured party has taken the steps required for non-temporal priority over a conflicting security interest in non-filing collateral (e.g., control, in the case of deposit accounts, letter-of-credit rights, and investment property). This rule determines priority in proceeds of non-filing collateral whether or not there exists an actual conflicting security interest in the original non-filing collateral. Under subsection (c)(2), the priority in the original collateral continues in proceeds if the security interest in proceeds is perfected and the proceeds are cash proceeds or non-filing proceeds “of the same type” as the original collateral. As used in subsection (c)(2), “type” means a type of collateral defined in the Uniform Commercial Code and should be read broadly. For example, a security is “of the same type” as a security entitlement (i.e., investment property), and a promissory note is “of the same type” as a draft (i.e., an instrument).

(18) Proceeds of Non-Filing Collateral: Special Temporal Priority. Under subsections (d) and (e), if a security interest in non-filing collateral is perfected by a method other than filing (e.g., control or possession), it does not retain its priority over a conflicting security interest in proceeds that are filing collateral. Moreover, it is not entitled to priority in proceeds under the first-to file-or-perfect rule of subsections (a)(1) and (b). Instead, under subsection (d), priority is determined by a new first-to-file rule.

(19) Priority in Supporting Obligations. Under subsections (b)(2) and (c)(1), a security interest having priority in collateral also has priority in a supporting obligation for that collateral. However, the rules in these subsections are subject to the special rule in Section 9-329 governing the priority of security interests in a letter-of-credit right. See subsection (f). Under Section 9-329, a secured party’s failure to obtain control (Section 9-107) of a letter-of-credit right that serves as supporting collateral leaves its security interest exposed to a priming interest of a party who does take control.

(20) Unperfected Security Interests. Under subsection (a)(3), if conflicting security interests are unperfected, the first to attach has priority. This rule may be of merely theoretical interest, inasmuch as it is hard to imagine a situation where the case would come into litigation without either secured party’s having perfected its security interest. If neither security interest had been perfected at the time of the filing of a petition in bankruptcy, ordinarily neither would be good against the trustee in bankruptcy under the Bankruptcy Code.

(21) Agricultural Liens. Statutes other than this Article may purport to grant priority to an agricultural lien as against a conflicting security interest or agricultural lien. Under subsection (g), if another statute grants priority to an agricultural lien, the agricultural lien has priority only if the same statute creates the agricultural lien and the agricultural lien is perfected. Otherwise, subsection (a) applies the same priority rules to an agricultural lien as to a security interest, regardless of whether the agricultural lien conflicts with another agricultural lien or with a security interest.
