Item 4.01. Changes in Registrant’s Certifying Accountants

On September 14, 2018, we appointed Moore Stephens CPA Limited (“MS”) to replace our principal independent accountant, MNP LLP (“MNP”). The decision was approved by the Board of Directors of TGS International, Ltd. (the “Company”).

There were no disagreements between the Company and MNP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, from the time of MNP’s engagement up to the date of dismissal which disagreements that, if not resolved to MNP’s satisfaction, would have caused MNP to make reference to the subject matter of the disagreement in connection with its report issued in connection with the audit of the Company’s financial statements. None of the reportable events described under Item 304(a)(1)(v)(A)-(D) of Regulation S-K occurred within the two fiscal years of the Company ended February 28, 2018 and 2017 and subsequently up to the date of dismissal. The audit report of MNP on the financial statements of the Company as of February 28, 2018 did not contain any adverse opinion or disclaimer of opinion, and such audit report was not qualified or modified as to uncertainty, audit scope or accounting principles, except for MNP’s explanatory paragraph regarding the Company’s ability to continue as a going concern. A letter from MNP addressed to the Securities and Exchange Commission stating that it concurs with the statements made by the Company with respect to MNP in this Current Report on Form 8-K. A copy of such letter is furnished hereto with the filing of this Current Report on Form 8-K.

During the fiscal year of the Company ended February 28, 2018 and through the date of MS engagement, the Company did not consult MS regarding either: (i) the application of accounting principles to a specified transaction (either completed or proposed), or the type of audit opinion that might be rendered on the Company’s financial statements; or (ii) any matter that was either the subject of a “disagreement” or “reportable event” within the meaning set forth in Regulation S-K, Item 304 (a)(1)(iv) or (a)(1)(v).
