     Closure of Wafer Fabrication Facility in Sunnyvale
     The Company ceased production at its California wafer fabrication facility in November 2006. The Company paid the related lease obligation costs on a monthly basis over the remaining lease term, which expired in March 2010. The Company recorded a one-time settlement charge of $0.4 million in the first quarter of fiscal 2010 related to the termination of the lease. This action was completed during fiscal 2010.
     Reduction of Operating Costs
     During the fourth quarter of fiscal 2008, in order to further reduce its operating cost structure, the Company recorded a special charge of $1.6 million for severance and fringe benefit costs in accordance with its ongoing benefit plan or statutory requirements at foreign locations for 19 engineering, and selling, marketing, general and administrative (SMG&A) employees.
     During fiscal 2009, the Company recorded an additional charge of $30.3 million related to this cost reduction action. Approximately $2.1 million of this charge was for lease obligation costs for facilities that the Company ceased using during the first quarter of fiscal 2009; approximately $0.8 million was for the write-off of property, plant and equipment no longer used as a result of this action; and approximately $0.5 million was for contract termination costs and approximately $0.3 million was for clean-up and closure costs that were expensed as incurred. The remaining $26.6 million related to the severance and fringe benefit costs recorded in accordance with the Company’s ongoing benefit plan or statutory requirements at foreign locations for 245 manufacturing employees and 302 engineering and SMG&A employees.
     During the first quarter of fiscal 2010, the Company recorded an additional charge of $11.4 million related to the further reduction of its operating cost structure. Approximately $10.9 million of this charge was for severance and fringe benefit costs recorded in accordance with the Company’s ongoing benefit plan or statutory requirements at foreign locations for 149 engineering and SMG&A employees. Approximately $0.5 million of the charge relates to the Company’s decision to abandon efforts to develop a particular expertise in power management, resulting in the impairment of related intellectual property.
     The Company terminated the employment of all employees associated with this action and is paying amounts owed to them as income continuance.
     Closure of a Wafer Fabrication Facility in Cambridge
     During the first quarter of fiscal 2009, the Company recorded a special charge of $22.1 million as a result of its decision to consolidate its Cambridge, Massachusetts wafer fabrication facility into its existing Wilmington, Massachusetts facility. In connection with the anticipated closure of this facility, the Company evaluated the recoverability of the facility’s manufacturing assets and concluded that there was an impairment of approximately $12.9 million based on the revised period of intended use. The remaining $9.2 million was for severance and fringe benefit costs recorded in accordance with the Company’s ongoing benefit plan for 175 manufacturing employees and 9 SMG&A employees associated with this action.
     The Company finished production in the Cambridge wafer fabrication facility and began clean-up activities during the fourth quarter of fiscal 2009. During the fourth quarter of fiscal 2009, the Company reversed approximately $1.8 million of its severance accrual. The accrual reversal was required because 51 employees either voluntarily left the Company or found alternative employment within the Company. In addition, the Company recorded a special charge of approximately $1.7 million for the impairment of manufacturing assets that were originally going to be moved to the Company’s other wafer fabrication facilities but were no longer needed at those facilities and therefore had no future use. The Company also recorded a special charge of $0.1 million for clean-up costs as the Company began its clean-up of the Cambridge wafer fabrication facility at the end of the fourth quarter of fiscal 2009.
     During the first quarter of fiscal 2010, the Company recorded an additional charge of $4.7 million related to this cost reduction action. Approximately $3.4 million of the charge related to lease obligation costs for the Cambridge wafer fabrication facility, which the Company ceased using in the first quarter of fiscal 2010. The remaining $1.3 million of the charge related to clean-up and closure costs that were expensed as incurred. This action was completed during the third quarter of fiscal 2011.
