(a) Evaluation of disclosure controls and procedures
In accordance with Exchange Act Rule 13a-15, we carried out an evaluation, under the supervision and with the participation of management, including our chief executive officer, principal accounting officer, and principal financial officer (the Executives), of the effectiveness of our disclosure controls and procedures as of March 31, 2009. In designing and evaluating the disclosure controls and procedures, the Executives recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is necessarily required to apply judgment in evaluating the cost-benefit relationship of possible controls and objectives. Based on that evaluation, the Executives concluded that our disclosure controls and procedures are effective as of March 31, 2009, in timely making known to them material information relating to us and our consolidated subsidiaries required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934. We have investments in certain unconsolidated entities. As we do not control these entities, our disclosure controls and procedures with respect to such entities are necessarily substantially more limited than those we maintain with respect to our consolidated subsidiaries.
