    (c) Assessed costs must be entered in United States dollars.
    (d) Each payment in United States dollars must be accepted and credited on a judgment or award on a foreign-money claim in the amount of the foreign money that could be purchased by the dollars at a bank-offered spot rate of exchange at or near the close of business on the conversion date for that payment.
    (e) A judgment or award made in an action or distribution proceeding on both (i) a defense, set-off, recoupment, or counterclaim and (ii) the adverse party's claim, must be netted by converting the money of the smaller into the money of the larger, and by subtracting the smaller from the larger, and specify the rates of exchange used.
