Bonds in class actions; limitations.

(1) In any civil action that is brought as a certified class action, the trial court, upon the posting of a bond or equivalent surety as provided in this section, shall stay the execution of any judgment, or portion thereof, entered on account of punitive damages pending completion of any appellate review of the judgment.

(2) The required bond or equivalent surety acceptable to the court for imposition of the stay shall be the lower of:

(a) The amount of the punitive-damages judgment, plus twice the statutory rate of interest; or

(b) Ten percent of the net worth of the defendant as determined by applying generally accepted accounting principles to the defendant’s financial status as of December 31 of the year prior to the judgment for punitive damages;

provided that in no case shall the amount of the required bond or equivalent surety exceed $100 million, regardless of the amount of punitive damages.

(3) If, at any time after notice and hearing, the court finds that a defendant who has posted a bond or equivalent surety pursuant to subsection (2) is purposefully moving assets with the intent to avoid the punitive-damages judgment, the court shall increase the bond or equivalent surety to the amount determined pursuant to paragraph (2)(a). If the defendant does not post the additional bond required by the court, the stay shall be revoked.
