NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued) The preliminary amount of the purchase price allocated to identified intangible assets recognized in the acquisition of SiGe and the respective estimated useful lives as of June 10, 2011 were as follows (in thousands): Fair Value Weighted Average Amortization Period (in Years) Intellectual property ......................................... $36,660 5 Customer relationships ....................................... 26,200 5 In-process research and development ........................... 4,510 TBD Backlog ................................................... 3,900 0.3 Trademark ................................................ 3,000 5 Total identifiable intangible assets ............................ $74,270 Intellectual property primarily represents the fair value of the SiGe product technologies (including patents) acquired. Customer relationships represent the fair value of the underlying relationships and agreements with SiGe customers. In-process research and development represents the fair value of incomplete SiGe research and development projects that had not reached technological feasibility as of the acquisition date, June 10, 2011. Because of the uncertainty related to the completion of these projects, the Company has determined that the amortization period will be established when the projects are completed. If a project is determined to be cancelled or does not meet technological feasibility, the value associated with that project will be written off in the period the determination is made. Backlog represents the fair value of SiGe unfilled orders as of the acquisition date, June 10, 2011. The trademark represents the brand and name recognition associated with the marketing of SiGe products and was determined to have a finite life. The Company used a combination of income approaches to assess the preliminary fair values of the intangible assets and as a result, considers the fair value of these acquired assets to be Level 3 assets due to the significant assumptions used in the valuation. See Note 5, Fair Value for the definition of Level 3 assets. Net revenue and net income for acquisitions completed during the fiscal year ended September 30, 2011 have been included in the consolidated statements of operations from their respective acquisition dates. SiGe contributed approximately $39.7 million of net revenue to the consolidated results of operations for the fiscal year ended September 30, 2011. The impact of SiGe’s ongoing operations on the Company’s net income was insignificant to the fiscal year ended September 30, 2011. The transaction related costs associated to the SiGe acquisition were considered immaterial and included within selling, general and administrative expense for the fiscal year ended September 30, 2011. The unaudited pro forma financial results for the fiscal years ended September 30, 2011 and October 1, 2010 combine the unaudited historical results of Skyworks along with the unaudited historical results of SiGe for the fiscal years ended September 30, 2011 and October 1, 2010, respectively. The results include the effects of unaudited pro forma adjustments as if SiGe was acquired on October 3, 2009. There were no material nonrecurring pro forma adjustments in the calculation of revenue or earnings. The pro forma financial results presented below do not include any anticipated synergies or other expected benefits of the acquisition. These results are presented for informational purposes only and are not necessarily indicative of future operations (in thousands, except per share amounts): Fiscal Years Ended September 30, 2011 October 1, 2010 Revenue ................................................... $1,490,960 $1,174,057 Net income ................................................. $ 209,016 $ 129,258 Basic EPS .................................................. $ 1.14 $ 0.74 Diluted EPS ................................................ $ 1.10 $ 0.71 Page 100 Skyworks / Annual Report 2011
