2. Acquisition On December 15, 2016, the Company acquired certain assets and liabilities of Camouflage Software Inc. (Camouflage), a private company based in Newfoundland, Canada. Camouflage is a provider of data management, security and data masking solutions. The Company acquired Camouflage for cash consideration of $4.5 million. Approximately $0.6 million of the consideration is a holdback payment commitment due 24 months from the date the acquisition closes. Imperva acquired certain tangible assets and also assumed liabilities of Camouflage. Substantially all of the consideration was allocated to goodwill and intangible assets, such as developed technology, customer relationships and trade name. The acquisition was accounted for in accordance with Accounting Standards Codification (ASC) No. 805, Business Combinations, and the results of operations of the acquisition have been included in the Companys consolidated results of operations from the date of the acquisition. The acquisition was not material to the Companys results of operations in the period of acquisition. The purchase consideration allocated to the tangible assets acquired is assigned based on the fair values as of the date of the acquisition. The Company believes that these identified intangible assets will have no residual value after their estimated economic useful lives. The identifiable intangible assets are subject to amortization on a straight-line basis over a seven-year estimated useful life as this best approximates the benefit period related to these assets. The excess of the purchase consideration over the identified tangible and intangible assets, less liabilities assumed, is recorded as goodwill and primarily reflects the value of the synergies expected to be generated from combining the Companys and the acquired entities technology and operations. The following table summarizes the allocation of the consideration to the fair value of the tangible and intangible assets acquired and liabilities assumed as of the acquisition date
