The Board or the Committee will also review the facts and circumstances underlying the restatement, and if any incentive award was calculated based on the achievement of financial results that were subsequently reduced due to a restatement, may in its discretion (i) require reimbursement to the Company of all or a portion of the incentive award; (ii) cancel any unvested or outstanding incentive award; and (iii) seek reimbursement of any gains realized on the exercise of the incentive awards.
