Business Combinations and Divestitures	Business Combinations and Divestitures Acquisitions In the first quarter of 2019, we made no acquisitions of businesses. In the first quarter of 2018, we acquired the remaining 50% equity interest in our Qatari joint venture that we previously accounted for as an equity method investment and consolidated the entity.

The total consideration to purchase the remaining equity interest was $87 million, which is comprised of a cash consideration of $72 million and an estimated contingent consideration of $15 million related to services the Qatari entity will render under new contracts.
