CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT On April 3, 2002, Innovative Solutions and Support, Inc. (the "Company") informed its independent accountants, Arthur Andersen LLP ("Andersen"), that they would be dismissed effective as of April 3, 2002. The reports of Andersen on the Company's financial statements for the years ended September 30, 2000 and September 30, 2001, 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 its audits for the fiscal years ended September 30, 2000 and September 30, 2001, and for the subsequent interim period through the date of this Form 8-K, (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 such disagreements in their reports, and (ii) there have been no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K. The Company's Audit Committee and Board of Directors authorized the dismissal of Andersen and directed management to interview the four remaining national accounting firms and select one of them as the company's independent auditor. The Company has completed these evaluations, has narrowed the selection, and is waiting for the customary new-client acceptance procedures to be completed. The Company will announce its final decision as soon as that process is completed. During the Company's two most recent fiscal years, and for the subsequent interim period through the date of this Form 8-K, the Company did not consult with the above firms regarding any of the items described in Item 304(a)(2) of Regulation S-K. Pursuant to Item 304(a)(3) of Regulation S-K, the Company has requested Andersen to furnish it a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements. A copy of that letter is filed as an Exhibit to this Form 8-K. ITEM 7.
