Changes in Registrant's Certifying Accountant. On July 28, 2004, Vical Incorporated (the "Company") made the decision to dismiss KPMG LLP ("KPMG") as its independent auditor upon the completion of their review of the Company's financial statements for the period ended June 30, 2004. On the same date, the Company engaged Deloitte & Touche LLP ("Deloitte") to serve as its independent auditor for fiscal periods subsequent to the quarter ended June 30, 2004. The decision to dismiss KPMG and engage Deloitte was approved by the Company's Audit Committee. The audit reports of KPMG on the financial statements of Vical Incorporated as of and for the years ended December 31, 2003 and 2002 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles; and there were no reportable events, as listed in Item 304(a)(1)(v) of Regulation S-K. In connection with the audits of the two fiscal years ended December 31, 2003, and the subsequent interim period through July 28, 2004, there were no disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to their satisfaction, would have caused them to make reference in connection with their opinion to the subject matter of the disagreement. A letter from KPMG is attached as Exhibit 16.1 to this Form 8-K. During the fiscal years ended December 31, 2003 and 2002, and the interim period between December 31, 2003 and July 28, 2004, neither the Company nor anyone acting on its behalf consulted with Deloitte regarding the application of accounting principles to a specified transaction, either completed or proposed, the type of audit opinion that might be rendered on the Company's financial statements, or any matters or reportable events listed in Item 304(a)(2)(ii) of Regulation S-K.
