The Board of Directors reviewed whether or not the Company should continue the retention of Andersen in light of recent events involving Andersen, and following its review, authorized the engagement of KPMG in lieu of Andersen. Andersen's reports on the Company's financial statements for the two most recent fiscal years did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the Company's two most recent fiscal years and the period from the end of the most recent fiscal year to the date of dismissal of Andersen, (i) there were no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which disagreements, if not resolved to Andersen's satisfaction, would have caused Andersen to make reference to the subject matter of the disagreement(s) in connection with its report and (ii) there were no "reportable events" as such term is defined in Item 304(a)(1)(v) of Regulation S-K. The Company provided Andersen with a copy of this Form 8-K prior to its filing with the Securities and Exchange Commission. Attached, as Exhibit 16, is a copy of Andersen's letter to the Securities and Exchange Commission stating its agreement with the statements concerning Andersen. During the Company's two most recent fiscal years and the period from the end of the most recent fiscal year to the date of engagement of KPMG, neither the Company nor anyone acting on its behalf consulted with KPMG with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, or any other matters or events set forth in Item 304(b)(2)(i) and (ii) of Regulation S-K.
