Item 4.01 Changes in Registrant's Certifying Accountant

As disclosed in its definitive proxy statement filed on March 20, 2015, Core Laboratories N.V. (the “Company”) intends to appoint the U.S. and Dutch member firms of KPMG (collectively, “KPMG”) to serve as the Company’s Independent Registered Public Accounting Firm for the year ending December 31, 2016, subject to the negotiation and execution of a satisfactory engagement letter and the approval of the Company’s shareholders at its May 21, 2015 annual meeting (the “annual meeting”). This change is prompted by Dutch regulations that mandate a rotation of public company auditors after a period of eight years and was approved by the Audit Committee of the Company’s Board of Supervisory Directors.

(a) Dismissal of Independent Registered Accounting Firm.

In connection with the Company’s engagement of KPMG (as discussed below), on April 29, 2015 (the “Dismissal Date”) the Company dismissed PricewaterhouseCoopers LLP ("PwC") as the Company’s independent registered public accounting firm effective upon the issuance by PwC of their reports on the consolidated financial statements as of and for the year ended December 31, 2015 and the effectiveness of internal control over financial reporting as of December 31, 2015 to be included in the filing of the related 10-K.

The reports of PwC on the Company’s consolidated financial statements for the fiscal years ended December 31, 2014 and 2013 did not contain an adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principle.

During the fiscal years ended December 31, 2014 and 2013 and the subsequent interim period through the Dismissal Date, there have been no disagreements with PwC on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure which, if not resolved to the satisfaction of PwC, would have caused PwC to make reference to the matter in their reports on the Company’s consolidated financial statements for such periods.

The Company has requested that PwC furnish a letter addressed to the Securities and Exchange Commission, pursuant to Item 304(a)(3) of Regulation S-K, stating whether or not PwC agrees with the statements in this Current Report on Form 8-K (this “Report”). A copy of such letter, dated May 4, 2015, is attached as Exhibit 16.1 to this Report.

(b) Engagement of New Independent Registered Accounting Firm.

The Company has reached agreement with KPMG on the terms of the prospective engagement and on April 29, 2015 executed an engagement letter with KPMG’s U.S. member firm, KPMG LLP, effective January 1, 2016 and subject to the approval of the Company’s appointment of KPMG by the Company’s shareholders at the annual meeting. The Company has also reached agreement on the terms of the engagement letter to be executed with KPMG’s Dutch member firm, KPMG Accountants N.V., which pursuant to Dutch practice, will be executed upon approval of the Company's appointment of KPMG by the Company's shareholders at the annual meeting.
