(1)In connection with the sale, we estimated the fair value of the existing parent company guarantees and bank and surety bonds considering the probability of default by Balcke Dürr and an estimate of the amount we would be obligated to pay in the event of a default. Additionally, we estimated the fair value of the cash collateral provided by Balcke Dürr and the guarantee provided by the parent company of the buyer based on the terms and conditions and relative risk associated with each of these securities (unobservable inputs - Level 3).

(2)We reduced the liability generally at the earlier of the completion of the related underlying project milestones or the expiration of the guarantees or bonds. We amortized the asset based on the expiration terms of each of the securities. We recorded the reduction of the liability and the amortization of the asset to “Other income (expense), net.”

(3)Balance associated with the guarantees and bonds is reflected within "Other long-term liabilities" within the accompanying consolidated balance sheet as of December 31, 2020.
