CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT Effective May 20, 2002, in view of recent widely-known events involving its independent accountants, LaBranche & Co Inc. (the "Company") dismissed Arthur Andersen LLP as its independent accountants and engaged KPMG LLP as its new independent accountants for the remainder of the fiscal year ending December 31, 2002. The Company's Audit Committee recommended, and the Company's Board of Directors authorized and approved, the decision to replace Arthur Andersen LLP with KPMG LLP as the Company's independent accountants. The reports of Arthur Andersen LLP on the financial statements of the Company for the past two fiscal years have contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle. In connection with audits of the Company for the two most recent fiscal years and the subsequent interim period through May 20, 2002, there have been no disagreements between the Company and Arthur Andersen 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 Arthur Andersen LLP would have caused Arthur Andersen LLP, to make reference thereto in its reports on the financial statements of the Company for such years. During the two most recent fiscal years and the subsequent interim period through May 20, 2002, there have been no reportable events (as defined in Regulation S-K Item 304(a)(1)(v)) of the Company. During the two most recent fiscal years and the subsequent interim period through May 20, 2002, neither the Company nor any other person on its behalf has consulted with KPMG LLP on any application of accounting principles or any other matter set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K. The Company has requested that Arthur Andersen LLP furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of such letter is filed as Exhibit 16 to this Form 8-K. ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.
