Form 10-K for Fiscal Year Ended December 31, 2020 Filed March 15, 2021 File No. 001-15259 Dear Mr. Kirk: We have limited our review of your filing to the financial statements and related disclosures and have the following comment. In our comment, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this comment within ten business days by providing the requested information or advise us as soon as possible when you will respond. If you do not believe our comment applies to your facts and circumstances, please tell us why in your response. After reviewing your response to this comment, we may have additional comments. Form 10-K filed March 15, 2021 Note 2. Revisions of Previously Issued Financial Statements, page F-17 1. We note your disclosure that you identified certain immaterial errors in your historical financial statements primarily related to the accounting for (1) foreign currency exchange gains and losses associated with a specific reinsurance contract and (2) errors in the Company s tax provision primarily related to the Company s allocation of certain corporate-level expenses to your subsidiary companies, as well as other previously identified immaterial errors. We further note your disclosure that you concluded that although these errors were not material to the previously issued financial statements, however, correcting the cumulative effect of the errors in 2020 would materially misstate the 2020 consolidated financial statements, and therefore you have revised your historical financial statements to correct for these immaterial errors. In light of the nature of the errors and their quantitative significance to the adjusted financial statements presented, Scott Kirk Argo Group International Holdings, Ltd. December 17, 2021 Page 2 including, for instance income tax provision, net income (loss) and earnings per share for certain of the revised periods, please provide us with your analysis considering the guidance in Staff Accounting Bulletin No. 99. In your response please discuss how you evaluated the total mix of information, taking into account both quantitative and qualitative factors considered, when determining materiality of the error to investors and other users. In closing, we remind you that the company and its management are responsible for the accuracy and adequacy of their disclosures, notwithstanding any review, comments, action or absence of action by the staff. You may contact William Schroeder at 202-551-3294 or John Spitz at 202-551-3484 with any questions. FirstName LastNameScott Kirk Sincerely, Comapany NameArgo Group International Holdings, Ltd.
