Our report dated March 15, 2005, on management’s assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of December 31, 2004, expresses our opinion that Pixelworks, Inc. did not maintain effective internal control over financial reporting as of December 31, 2004 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that management identified a material weakness in internal control over financial reporting which resulted from the inadequate design of internal control related to management’s review of the Company’s accounting for income taxes and related disclosures.
