S-I/A Total identifiable net assets assumed 2,548 Goodwill 602 Total $3,150 Goodwill of $0.6 million arising from the acquisition consists primarily of the benefit of incorporating engineering talent from Minetta, and the full amount is deductible for tax purposes. The Company fair valued the acquired intangible assets totaling $2.4 million using the cost approach. The market and income approaches were not used given (1) there are no comparable transactions for technology at a similar development stage, and (2) Minetta had not generated any revenue as of the acquisition date. During December 2013, the Company determined that it needed to wind down the Minetta business and had no plans to utilize Minetta's technology in its own products. As the acquired intangible assets were not expected to contribute directly or indirectly to the future cash flows of the Company, and there were no other ways to monetize the technology, the Company recorded an impairment charge of $2.4 million to reduce the carrying value of the Minetta intangible assets to zero. The Company recorded the impairment charge within operating expenses during the year ended December 31, 2013.
