N.D. Admin. Code § 13-03-22-13
13-03-22-13. Valuing securities.
1. Before purchasing or selling a security, a credit union must obtain either price quotations on the security from at least two broker-dealers or a price quotation on the security from an industry-recognized information provider. This requirement to obtain price quotations does not apply to new issues purchased at par or at original issue discount.
2. At least monthly, a credit union must determine the fair value of each security it holds. It may determine fair value by obtaining a price quotation on the security from an industry-recognized information provider, a broker-dealer, or a safekeeper.
3. At least annually, the credit union's supervisory committee or its external auditor must independently assess the reliability of monthly price quotations received from a broker-dealer or a safekeeper. The credit union's supervisory committee or external auditor must follow generally accepted auditing standards, which require either recomputation or reference to market quotations.
4. If a credit union is unable to obtain a price quotation required by this section for a particular security, then it may obtain a quotation for a security with substantially similar characteristics.
