Item 4. Changes in Registrant’s Certifying Accountant

On April 30, 2004, Deloitte & Touche, LLP notified the Company that it has declined to stand for reelection as the Company’s independent auditors. The reports of Deloitte & Touche, LLP on the consolidated financial statements of the Company and its subsidiaries for the Company’s last two fiscal years did not contain an adverse opinion or a disclaimer of opinion, nor were they modified or qualified as to uncertainty, audit scope, or accounting principles in any respect. The decision to decline to stand for reelection was made by Deloitte & Touche, LLP and, accordingly, no action was taken by the Company’s audit committee to recommend or approve this change of accountants. During the Company’s last two fiscal years and through the interim period ended April 30, 2004, there were no disagreements between the Company and Deloitte & Touche, LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte & Touche, LLP, would have caused it to make reference to the subject matter of the disagreement in connection with its reports. Deloitte & Touche, LLP has reviewed this report. In this regard, Deloitte & Touche, LLP has provided the Company with the letter attached hereto as Exhibit 16.1.
