In the settlement of any claim pursuant to 10 U.S.C. 2733 and this subpart, attorney fees will not exceed 20 percent of any award provided that when a claim involves payment of an award over $1,000,000, attorney fees on that part of the award exceeding $1,000,000 may be determined by the Secretary of the Air Force. For the purposes of this paragraph, an award is deemed to be the cost to the United States of any trust or structured settlement, and not its future value.
