(b) A judgment will be significantly less favorable to the rejecting party than is the settlement offer if:
(1) the rejecting party is a claimant and the award will be less than 80 percent of the rejected offer; or
(2) the rejecting party is a defendant and the award will be more than 120 percent of the rejected offer.

(c) The litigation costs that may be recovered by the offering party under this section are limited to those litigation costs incurred by the offering party after the date the rejecting party rejected the settlement offer.
(d) The litigation costs that may be awarded under this chapter to any party may not be greater than the total amount that the claimant recovers or would recover before adding an award of litigation costs under this chapter in favor of the claimant or subtracting as an offset an award of litigation costs under this chapter in favor of the defendant.
(e) If a claimant or defendant is entitled to recover fees and costs under another law, that claimant or defendant may not recover litigation costs in addition to the fees and costs recoverable under the other law.
