Effective November 16, 2017, Hein & Associates LLP (“Hein”), the independent registered public accounting firm for Advanced Emissions Solutions, Inc. (the “Company”), combined with Moss Adams, LLP (“Moss Adams”). The combined entity will continue under the name Moss Adams, LLP. As a result of this transaction, on November 16, 2017, Hein resigned as the independent registered public accounting firm for the Company. Concurrent with such resignation, the Audit Committee of the Company's Board of Directors approved the engagement of Moss Adams, LLP as the new independent registered public accounting firm for the Company. The Company and Hein are parties to an arrangement letter dated November 16, 2017 (the "Letter") and the Company has consented to the assignment by Hein of its responsibilities under the Letter to Moss Adams LLP and Moss Adams, LLP's assumption of such responsibilities. As Hein’s former partners and employees are now part of Moss Adams LLP, the engagement team for the Company is expected to remain the same.
The audit reports of Hein on the Company’s financial statements for the years ended December 31, 2016 and 2015 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the two most recent fiscal years ended December 31, 2016 and through the subsequent interim period preceding Hein’s resignation, there were no disagreements between the Company and Hein on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Hein would have caused them to make reference thereto in their reports on the Company’s financial statements for such years.
During the two most recent fiscal years ended December 31, 2016 and through the subsequent interim period preceding Hein’s resignation, there were no reportable events within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K, except as described in the Report of the Independent Registered Public Accounting Firm including in Item 9A of the Company’s 2015 Annual Report on Form 10-K.
During the two most recent fiscal years ended December 31, 2016 and through the subsequent interim period preceding Moss Adams, LLP’s engagement, the Company did not consult with Moss Adams on either (1) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that may be rendered on the Company’s financial statements, and Moss Adams did not provide either a written report or oral advice to the Company that Moss Adams concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (2) any matter that was either the subject of a disagreement, as defined in Item 304(a)(1)(iv) of Regulation S-K, or a reportable event, as defined in Item 304(a)(1)(v) of Regulation S-K.
The Company has provided Hein a copy of the disclosures in this Form 8-K and has requested that Hein furnish it with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the Company’s statements herein. A copy of the letter dated
November 20, 2017
is filed as Exhibit 16.1 to this Form 8-K.
