Acquisition of Roving Networks

On April 18, 2012, the Company acquired Roving Networks, a privately-held company. Roving Networks is an innovator in low-power embedded Wi-Fi and Bluetooth solutions based in Los Gatos, California. The business acquisition was accounted for under the purchase method of accounting.  Total consideration paid for this business was approximately $20.6 million.  The acquisition also resulted in contingent consideration with an estimated fair value at the date of purchase of approximately $14.7 million. The initial purchase price of the acquisition resulted in purchased intangible assets of approximately $22.8 million and goodwill of approximately $8.7 million which was all allocated to the Company's semiconductor products segment.  Goodwill recognized in this transaction is non-deductible. Purchased intangible assets included $10.6 million of developed technology, $10.6 million of customer-related intangibles, $0.3 million of acquisition-date backlog and $1.3 million of in-process research and development. The purchased intangible assets (other than in-process technology and acquisition-date backlog) are being amortized over their expected useful lives which range between four and ten years. Acquisition-date backlog is being amortized over one year and in-process research and development is capitalized until such time the related projects are completed or abandoned at which time the capitalized amounts will begin to be amortized or written off.
