(a)
Dismissal of Independent Registered Public Accounting Firm
On September 18, 2017, Clean Diesel Technologies, Inc. (the
Company
) dismissed BDO USA, LLP (
BDO
) as our independent registered public accounting firm. The decision to dismiss BDO was approved by the audit committee of our board of directors.
The audit reports of BDO on our consolidated financial statements as of and for the fiscal years ended December 31, 2016 and 2015 did not contain an adverse opinion or disclaimer of opinion, and were not modified as to uncertainty, audit scope, or accounting principles, except that each of the audit reports on our consolidated financial statements as of and for the fiscal years ended December 31, 2016 and 2015 did contain an explanatory paragraph related to our ability to continue as a going concern.
In connection with the audit of our consolidated financial statements for the fiscal years ended December 31, 2016 and 2015, and for the subsequent period through the date of dismissal, there were: (i) no disagreements between us and BDO on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of BDO, would have caused BDO to make reference to the subject matter of the disagreements in its report on our consolidated financial statements for such fiscal years; and (ii) no reportable events within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.
We provided BDO with a copy of the disclosures in this Current Report on Form 8-K and requested that BDO furnish us with a letter addressed to the Securities and Exchange Commission stating whether or not BDO agrees with our statements in this Item 4.01. A copy of the letter dated September 18, 2017, furnished by BDO in response to that request is filed as Exhibit 16.1 to this Current Report on Form 8-K.

Engagement of New Independent Registered Public Accounting Firm
The audit committee of our board of directors approved the appointment of Rose, Snyder & Jacobs, LLP (
RSJ
) as our new independent registered public accounting firm, and we formally engaged RSJ as our independent registered public accounting firm on September 18, 2017.
During our two most recent fiscal years ended December 31, 2016 and 2015 and through September 18, 2017, neither we nor anyone on our behalf consulted with RSJ with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that may be rendered on our financial statements, and RSJ did not provide either a written report or oral advice to us that RSJ concluded was an important factor considered by us in reaching a decision as to any accounting, auditing, or financial reporting issue; or (ii) any matter that was the subject of any disagreement, as defined in Item 304 (a)(1)(iv) of Regulation S-K and the related instructions, or a reportable event within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.
