Item 2.05. Costs Associated with Exit or Disposal Activities

During the fiscal quarter ended December 27, 2008, in order to achieve its goal of attaining a lower operating results break-even point, Advanced Micro Devices, Inc. (the “Company”) implemented a restructuring plan to reduce its on-going cost structure (the “Plan”). The Plan primarily involves approximately 600 employees who were notified during the fourth quarter of fiscal 2008 that their employment with the Company would be terminated, and additional cost reduction actions that either have taken place during the fourth quarter of fiscal 2008 or will take place in fiscal 2009. As a result of its current analysis, the Company now estimates that the restructuring expense that it will record in the fourth quarter of fiscal 2008 will be approximately $70 million, based on the restructuring plan approved by the Company on December 19, 2008. Of this amount, approximately $34 million is related to severance and costs related to the continuation of certain employee benefits, approximately $13 million is related to contract or program termination costs, approximately $17 million is related to asset impairments and approximately $6 million is related to exit costs for facility site consolidations and closures. Of the $70 million, approximately $45 million will result in cash expenditures in fiscal 2009. Further cost reduction actions will result in additional charges in the first half of fiscal 2009, which the Company cannot estimate at this time, but which may include severance and costs related to the continuation of certain employee benefits, contract or program termination costs and facility site consolidations or closures. The Company will disclose its estimate or range of estimates for any additional charges in a filing with the Securities and Exchange Commission (“SEC”) promptly and in any event within four business days of determining such an estimate or range of estimates. Previously, the Company reported in its Quarterly Report on Form 10-Q for the third quarter of fiscal 2008 that it expected that the actions taken in the fourth quarter would involve approximately 500 employees and would result in a charge to operations in the fourth quarter of fiscal 2008 of approximately $50 million, consisting primarily of severance and costs related to the continuation of certain employee benefits, contract terminations and excess facility exit costs.

Item 2.06. Material Impairments

On December 19, 2008, the Company determined that it would incur a material charge for impairment of the following assets during the fiscal quarter ended December 27, 2008:

The Company expects that the impairment charge will be material, but, as of the time of this filing, the Company is unable to estimate the amount or range of amounts of the impairment charge. The Company will disclose such an estimate or range of estimates in a filing with the SEC promptly and in any event within four business days of determining such an estimate or range of estimates.

In addition, the Company will also perform an analysis to identify whether there is also potential impairment of any of the remaining identifiable intangible assets acquired in the ATI Acquisition. As of the time of this filing, the Company is unable to make a determination of an estimate of the amount or range of amounts of the impairment charge or whether it will be material. In the event the charge is material, the Company will disclose the amount in a filing with the SEC.

The Company will not be required to make any current or future cash expenditures as a result of these impairments. These impairment charges will be reflected in the Company’s financial statements as of and for the fiscal quarter and year ended December 27, 2008.

On December 26, 2008, the Company determined that it would incur an other-than-temporary investment impairment charge from its investment in Spansion Inc. during the fiscal quarter ended December 27, 2008 as follows:

This impairment charge will be reflected in the Company’s financial statements as of and for the fiscal quarter and year ended December 27, 2008.
