(c) A party seeking process, costs, bond, or other undertaking under subdivision (b) shall compute in United States dollars the amount of the foreign money claimed from a bank-offered spot rate prevailing at or near the close of business on the banking day next preceding the filing of a request or application for the issuance of process or for the determination of costs, or an application for a bond or other court-required undertaking.
