[1] A reconciliation of cash consideration to Payments for the CIQ Acquisition, net of cash acquired is as follows (in thousands):

[2] In connection with the Accu-Trade Acquisition, the Company entered into an agreement to provide one of the former owners with a one-year license to a certain product. The preliminary fair value of the license was determined to be $6.5 million, of which the Company received $1.2 million in cash upon the close of the Accu-Trade Acquisition. The $5.3 million difference between the fair value of $6.5 million and the $1.2 million in cash was recorded as non-cash consideration and the $6.5 million license fee was recorded in Other accrued liabilities as a contract liability on the Consolidated Balance Sheets and will be amortized into Other revenue on the Consolidated Statements of Income over the one-year contract term. The current period revenue related to the non-cash consideration of $5.3 million is a non-cash reconciling item titled Amortization of deferred revenue related to Accu-Trade Acquisition on the Consolidated Statements of Cash Flows.

[3] In connection with the CIQ Acquisition, CreditIQ’s unvested equity awards were cash-settled. The fair value of these awards was $9.6 million and was based on the price paid per common share to the owners of the acquired business and recognized immediately after the CIQ Acquisition in November 2021 as compensation expense in General and administrative expense on the Company’s Consolidated Statements of Income.
