Our report expresses our opinion that Wireless Facilities, 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 the material weakness in internal control over financial reporting related to the Company's procedures over period-ending closing journal entries related to income taxes.
