During the fiscal years ended December 31, 2018 and December 31, 2019, and through the subsequent interim period preceding S&G’s resignation, there were no disagreements between the Company and S&G 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 S&G would have caused them to make reference thereto in their reports on our financial statements for such years. During the fiscal years ended December 31, 2018 and December 31, 2019, and through the subsequent interim period preceding S&G’s resignation, there were no reportable events within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.   On December 30, 2020, the Company provided S&G with its disclosures in this Current Report on Form 8-K disclosing the resignation of S&G and requested in writing that S&G furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether they agree with such disclosure.
