After a remand from an appeal, post-judgment interest runs from the date of the original judgment if the appellate court merely modified that judgment, but runs from the judgment entered after the appeal if the appelate court reversed the original judgment.  Here, the appellate court had reversed, not modified the original attorney fee award so interest ran from entry of the new post-appeal judgment.  On the prior appeal, the appellate court’s directions required the trial court to do more than perform a pure mathematical computation or add or delete a category of fees; the trial court had to exercise its discretion to determine an appropriate award of attorneys’ fees.
