for customers’ costs to repair or replace the products in the field. A product recall or a significant number of product returns could be expensive, damage our reputation and could result in the shifting of business to our competitors. Costs associated with correcting defects, errors, bugs or other issues could be significant and could materially harm our financial results.



    In July 2008, we recorded a $196.0 million charge against cost of revenue to cover anticipated customer warranty, repair, return, replacement and other associated costs arising from a weak die/packaging material set in certain versions of our previous generation MCP and GPU products used in notebook systems. All of our newly manufactured products and all of our products that are currently shipping in volume have a different material set that we believe is more robust.

 

    The previous generation MCP and GPU products that are impacted were included in a number of notebook products that were shipped and sold in significant quantities. Certain notebook configurations of these MCP and GPU products are failing in the field at higher than normal rates. While we have not been able to determine a root cause for these failures, testing suggests a weak material set of die/package combination, system thermal management designs, and customer use patterns are contributing factors. We have worked with our customers to develop and have made available for download a software driver to cause the system fan to begin operation at the powering up of the system and reduce the thermal stress on these chips. We have also recommended to our customers that they consider changing the thermal management of the MCP and GPU products in their notebook system designs. We intend to fully support our customers in their repair and replacement of these impacted MCP and GPU products that fail, and their other efforts to mitigate the consequences of these failures.



    We continue to engage in discussions with our supply chain regarding reimbursement to us for some or all of the costs we have incurred and may incur in the future relating to the weak material set. We also continue to seek to access our insurance coverage, which provided us with $8.0 million in related reimbursement during fiscal year 2009. However, there can be no assurance that we will recover any additional reimbursement. We continue to not see any abnormal failure rates in any systems using NVIDIA products other than certain notebook configurations. However, we are continuing to test and otherwise investigate other products. There can be no assurance that we will not discover defects in other MCP or GPU products.



    Determining the amount of the $196.0 million charge related to this issue required management to make estimates and judgments based on historical experience, test data and various other assumptions including estimated field failure rates that we believe to be reasonable under the circumstances. The results of these judgments formed the basis for our estimate of the total charge to cover anticipated customer warranty, repair, return and replacement and other associated costs. However, if actual repair, return,
