Business Combinations [Abstract] |
Acquisitions | BUSINESS COMBINATIONS On April 27, 2011, the Company acquired 100% ownership of a private company engaged in the design and manufacturing of optical components for $28.8 million (net of cash acquired and including an estimated fair value of $2.0 million of contingent consideration which is not materially different than the maximum earn-out level). The acquisition has an immaterial impact to the Company’s results of operations (i.e., contributed less than one percent of net revenue for the fiscal year ended September 30, 2011) and accordingly, the disclosures required per the business combination topic of the Accounting Standards Codification have been excluded from this annual report on Form 10-K. Although the purchase price allocation is preliminary, the Company has recognized assets primarily related to intellectual property, land, building and goodwill. On June 10, 2011, the Company completed the acquisition of SiGe Semiconductor, Inc. (“SiGe”), a semiconductor provider. The Company acquired a 100% ownership interest in SiGe for an aggregate purchase price of $278.9 million in cash, including contingent consideration, payable in cash, approximately one year from the acquisition date, with an estimated fair value of $57.4 million. The possible outcome of the contingent consideration ranges from zero to $65.0 million and is based on the achievement of a specified revenue target over the twelve month period following the date of the acquisition. SiGe is a leading global supplier of RF front-end solutions that facilitate wireless multimedia across a wide range of applications. The acquisition of SiGe complements the Company’s leadership in wide area front-end solutions by adding SiGe's innovative short range, silicon-based products. As a result, the Company now offers customers a more comprehensive wireless networking product portfolio, supporting all key operating frequencies with greater architectural flexibility to address a variety of high growth applications. The allocation of purchase price consideration in the Company’s acquisition of SiGe to the assets and liabilities was not finalized at the time of filing this annual report on Form 10-K due to the proximity of the acquisition date of June 10, 2011 to the end of the fiscal year, September 30, 2011. The Company has, however, completed a preliminary purchase price allocation and accordingly, the Company has reflected a preliminary allocation of the purchase price in the accompanying financial statements. The preliminary allocation of the purchase price was based upon estimates and assumptions which are subject to change within the measurement period (up to one year from the acquisition date). The preliminary allocation of the purchase price is based on the estimated fair values of the assets acquired and liabilities assumed by major class related to the SiGe acquisition and are reflected in the accompanying financial statements as follows (in thousands):
| June 10, 2011
Estimated fair value of assets acquired |
Cash and cash equivalents | $ | 6,689 |
Receivables, net | 14,176 |
Inventory | 17,457 |
Other current assets | 2,942 |
Property, plant and equipment | 3,551 |
Deferred tax assets, net | 20,648 |
Intangible assets | 74,270 |
Goodwill | 162,387 |
Total assets acquired | 302,120 |
Estimated fair value of liabilities assumed |
Total liabilities assumed | (23,188 | )
Net assets acquired | $ | 278,932 |
The allocation of purchase price is considered preliminary until the end of the measurement period. However, during the fiscal year ended September 30, 2011, the Company recorded adjustments to its purchase accounting for SiGe as reported during the third fiscal quarter. The Company reduced the total consideration paid as a result of a net working capital adjustment and recorded additional deferred tax assets. Both of these adjustments resulted in a reduction of goodwill as of September 30, 2011. The preliminary amount of purchase price allocated to goodwill of $162.4 million relates to revenue and cost synergies the Company expects to capitalize on as a result of the business combination. Substantially all of the goodwill recognized as a result of the SiGe acquisition is not expected to be deductible for tax purposes. 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 |
Pending acquisition On May 26, 2011, the Company announced it had entered into an agreement and plan of merger (the “Merger Agreement”) with PowerCo Acquisition Corp., a wholly owned subsidiary of the Company (“Merger Sub”) and Advanced Analogic Technologies Incorporated (“AATI”) pursuant to which the Merger Sub will, subject to the satisfaction or waiver of the conditions in the Merger Agreement, merge with and into AATI, and AATI will survive the merger and become a wholly owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by the Company, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically be converted into the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of the Company’s common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of the stock consideration was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30-trading days prior to May 26, 2011. At that average price, the stock consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. If the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock. If the Company’s average last reported sale price during the pre-closing measurement period is less than $21.00 per share, the Company has the right to pay the entire $6.13 in cash, and in that event, AATI stockholders would not receive any shares of the Company’s Common Stock in the merger for their outstanding shares of AATI common stock, and would instead receive $6.13 entirely in cash. In the event that the Company's stock price is below $21.00 per share on the date of acquisition and elects an all cash transaction, the Company expects to pay approximately $190.0 million to $200.0 million in cash net of approximately $80.0 million to $90.0 million of cash expected to be acquired in the transaction. For additional information regarding the pending acquisition, see Note 14, Contingencies.
