Business combination description				In exchange for contributing accounts receivable to the Vendor Trust, the participating vendors were required to refrain from bringing legal claims regarding any overdue payment and forbear from exercising remedies on any payables tendered to and accepted by the Vendor Trust. FF’s suppliers and contractors holding aggregate past due payables of approximately $116.1 million contributed payables to the Vendor Trust in exchange for interests in the Vendor Trust. Certain FF suppliers and contractors also ultimately received interests in the Vendor Trust related to approximately $8.4 million of purchase orders for goods and services to be provided in the future. During September and October 2020, FF paid an aggregate of $4.5 million to the Vendor Trust, thus reducing the aggregate past due principal payables and purchase orders held by the Vendor Trust to approximately $136.6 million. In the fourth quarter of 2020, the Vendor Trust agreed to amend the agreement governing the satisfaction of interests in the Vendor Trust to permit the conversion of the interests in the Vendor Trust to equity interests in PSAC in connection with the Business Combination. In June 2021, FF and the Vendor Trust further agreed to allow the holders of interests in the Vendor Trust to elect to receive up to $10.0 million in cash in the aggregate upon closing of the Business Combination, which would reduce on a dollar-for-dollar basis the number of equity interests to be issued to such holders in satisfaction of their interests in the Vendor Trust. Fifty-three (53) of the holders of interests in the Vendor Trust elected to participate in the $10.0 million cash distribution at the closing of the Business Combination, and the remaining interests in the Vendor Trust were settled through the conversion of interests into Class A Common Stock and payment of cash at the closing of the Business Combination.
