Discussions between the parties were initiated by PWC; however, during the registrant's two most recent fiscal years and subsequent interim periods, no reports or financial statements issued by PWC contained an adverse opinion or disclaimer of opinion or was qualified or modified as to uncertainty, audit scope or accounting principles. Further, during the Registrant's two most recent fiscal years and subsequent interim periods there were no disagreements between the Registrant's management and PWC 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 PWC, would have caused PWC to make reference to the subject matter of the disagreements in connection with PWC's reports.
