(b) Managements Annual Report on Internal Control over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act). Our internal control system was designed to provide reasonable assurance as to the integrity and reliability of the published financial statements. All internal control systems, no matter how well designed, have inherent limitations and can provide only reasonable assurance that the objectives of the control system are met.
Management evaluated the internal control over financial reporting under the supervision of our Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO, as of December 31, 2008. Management evaluated the effectiveness of our internal control over financial reporting based on the criteria set out in the Committee of Sponsoring Organizations of the Treadway Commission (COSO) framework. Our management concluded that as of December 31, 2008, our internal control over financial reporting was adequate and effective, based on those criteria.
