As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our President and Chief Executive Officer and our Senior Vice President - Finance and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 and Rule 15d-15 of the Securities Exchange Act of 1934, as amended (the Exchange Act). Based upon that evaluation, our President and Chief Executive Officer and our Senior Vice President - Finance and Chief Financial Officer concluded that as of the end of the period covered by this report our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and accumulated and communicated to our management including our President and Chief Executive Officer and our Senior Vice President - Finance and Chief Financial Officer, to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting identified in connection with the evaluation that occurred during the periods covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
