Item 4.01 Changes in Registrant’s Certifying Accountant.

 

On September 13, 2018, PricewaterhouseCoopers (“PwC”) was dismissed as the PDF Solutions, Inc. (the “Company”) independent registered public accounting firm.  The Audit Committee (the “Committee”) of the Board of Directors of PDF Solutions, Inc. (the “Company”) participated in and approved the decision to change the Company’s independent registered public accounting firm on September 12, 2018.     

 

The reports of PwC on the Company’s consolidated financial statements for the fiscal years ended December 31, 2017 and 2016 and for each of the two years in the period ended December 31, 2017 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. In connection with the audits of the Company’s consolidated financial statements for the fiscal years ended December 31, 2017 and 2016, and in the subsequent interim period through September 13, 2018, there were no disagreements with PwC on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedures which, if not resolved to the satisfaction of PwC, would have caused PwC to make reference to the matter in their report. There were no reportable events (as that term is described in Item 304(a)(1)(v) of Regulation S-K) during the two fiscal years ended December 31, 2017 and 2016, or in the subsequent period through September 13, 2018.

 

The Company has provided a copy of the foregoing disclosures to PwC and requested that PwC furnish it with a letter addressed to the Securities and Exchange Commission stating whether PwC agrees with the above statements. A copy of PwC’s letter, dated September 18, 2018, is filed as Exhibit 16.1 to this Form 8-K.

 

The Committee approved the appointment of BPM LLP (“BPM”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2018, subject to completion of its standard client acceptance procedures.  During the two most recent fiscal years and in the subsequent interim period through September 13, 2018, the Company has not consulted with BPM with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that would have been rendered on the Company’s consolidated financial statements, or any other matters set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.
