Acquisition of Mattersight Corporation: On August 20, 2018, the Company completed the acquisition of Mattersight Corporation ("Mattersight"), a leading provider of cloud based analytics for customer service organizations. The Company acquired Mattersight for total consideration of $105,053. Upon acquisition, Mattersight became a wholly-owned subsidiary of the Company. The acquisition was accounted for as a business combination. This method requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. The Company recorded core technology, customer relationships, customer backlog and goodwill in amount of $50,852; $7,757; $5,439 and $48,579, respectively. The estimated useful life of the core technology, customer relationships, and customer backlog are 5-7 years, 7 years, and 2-3 years, respectively. Goodwill generated from this business combination is attributed to synergies between the Company's and Mattersight's respective products and services. The goodwill is not deductible for income tax purposes. The preliminary fair value estimates for the assets acquired and liabilities assumed for this acquisition were based upon preliminary calculations and valuations, and the estimates and assumptions for this acquisition are subject to change as the Company obtains additional information during the measurement period (up to one year from the acquisition date). The results of Mattersight's operations have been included in the consolidated financial statements since August 20, 2018. Pro forma results of operations related to this acquisition have not been prepared because they are not material to the Company's consolidated statement of income. 2.

In the aggregate, the total purchase price for these acquisitions was approximately $76,870. The Company preliminarily recorded $2,291 of net tangible liabilities and $51,015 of identifiable intangible assets, based on their estimated fair values, and $28,145 of residual goodwill. The fair value of assets acquired and liabilities assumed from those acquisitions were based on a preliminary valuation which was finalized during 2018 as part of the measurement period.
