For the six months ended June 30, 2021, the Company completed two acquisitions for an aggregate purchase price consideration of approximately $119 million. The aggregate purchase price was comprised of $96 million of cash, subject to working capital adjustments, and an estimated $23 million of contingent consideration if certain financial and profitability thresholds are achieved following the closing of the transactions. These acquisitions primarily expanded the Company’s offering in the U.S. to provide the rental, sale and service of surface-mounted horizontal pumping systems and horizontal jet pumping systems, as well as, to provide engineering and construction services. The Company has included the financial results of the acquisitions in its consolidated financial statements from the date of each acquisition.

The fair value of contingent consideration liabilities was determined using the Monte Carlo simulation that includes level 3 inputs such as probability-weighted cash flows and discount rates that range from 14.5% to 14.7%. One acquisition has a maximum contingent payment of approximately $6 million and one has no maximum. As a result, the Company recognized the estimated acquisition date fair value of contingent consideration liabilities of approximately $19 million in other current liabilities and approximately $4 million in other long-term liabilities in the consolidated balance sheets. Changes in the fair value of contingent consideration liabilities subsequent to the acquisition dates, such as changes in the forecasted operating results, are recognized in the period when the change in estimated fair value occurs and may materially impact the consolidated financial statements.

In 2021, the Company performed its preliminary valuations as of the applicable acquisition dates of the acquired net assets and recognized estimated goodwill of $66 million and intangible assets of $11 million in the U.S. segment, which are subject to change. If additional information is obtained about these assets and liabilities within the measurement period (not to exceed one year from the date of acquisition), through physical asset inspections and learning more about the newly acquired businesses, the Company will refine its estimate of fair value to allocate the purchase price more accurately.

The following table summarizes the purchase price allocation detail (in millions):

The Company has not presented supplemental pro forma information because the acquired operations did not materially impact the Company’s consolidated operating results. One acquisition involved a party with which one of the Company’s Board of Directors is affiliated. See “Capital Spending” in Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” for additional information. For the six months ended June 30, 2021, the Company recognized approximately $1 million of acquisition-related costs.
