Plain-English Summary
Prejudgment interest on a foreign-money claim isn't governed by a special rate under this Act. Instead, it follows whatever substantive law applies under Oklahoma's conflict-of-laws rules — except that the court or arbitrator must adjust it up or down if Oklahoma law on settlement or judgment offers, or on a party's delay tactics, calls for that.
Postjudgment interest is simpler: a judgment or award on a foreign-money claim bears interest at the same rate that applies to judgments of this state generally, tying it directly to the current judgment-interest rate under Section 727.1.
