5. Acquisitions Acquisition of OMGPOP . On March 21, 2012, we acquired 100% of the outstanding stock of OMGPOP, Inc., a provider of social games for mobile phones, tablets, PCs and social network sites, for purchase consideration of approximately $183.1 million in cash. We acquired OMGPOP to expand our social games offerings, particularly on mobile platforms. As a result of this acquisition, we recorded $82.3 million of developed technology, $33.3 million of branding intangible assets, $5.5 million of net tangible assets acquired, $42.1 million of deferred tax liabilities assumed and $104.3 million of residual goodwill. Goodwill from the acquisition represents the excess of the purchase price over the net tangible and intangible assets acquired and is not deductible for tax purposes. Goodwill recorded in connection with this acquisition is primarily attributable to the assembled workforce of the acquired business and the synergies expected to arise after our acquisition of the business. The preliminary fair values of assets acquired and liabilities assumed for the acquisition are subject to change as we obtain additional information for our estimates during the respective measurement period, up to one year. The primary areas that are not yet finalized relate to certain tangible assets and liabilities, acquired income and non-income based taxes and residual goodwill. The results of OMGPOP have been included in our consolidated results of operations from the date of acquisition and were not material. The useful lives for the developed technology and branding intangible assets acquired in the OMGPOP acquisition are expected to be three years and seven years, respectively, and will be amortized on a straight-line basis.
