Item 4. Controls and Procedures

Management’s Evaluation of Disclosure Controls and Procedures

The company’s management, with the participation of the company’s chief executive officer and chief financial officer, has evaluated the effectiveness of the company’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on such evaluation, the company’s chief executive officer and chief financial officer concluded that, as of the end of such period, the company’s disclosure controls and procedures were effective at the reasonable assurance level.
