The Company is a "foreign private issuer" as defined in Rule 3b-4 under the Exchange Act and Rule 405 under the Securities Act of 1933, as amended. Equity securities of the Company are accordingly exempt from Sections 14(a), 14(b), 14(c), 14(f) and 16 of the Exchange Act pursuant to Rule 3a12-3 thereunder.This Amendment No. 1 to the Annual Report ("Amendment No. 1") amends the Annual Report for the year ended December 31, 2021, which was originally filed with the U.S. Securities and Exchange Commission (the "SEC") on March 9, 2022. This Amendment No. 1 is being filed to restate the Company's audited annual financial statements for the three and twelve months ended December 31, 2021 (the "Financial Statements"). Subsequent to the original issuance of the Financial Statements, the Audit Committee of the Company's Board of Directors (the "Audit Committee"), with the assistance of outside counsel and consultants and in discussion with the Company's auditors, conducted a review of certain purchases and sales of products through the Company's wholesale channel to determine whether they had commercial substance, and to confirm the timing and appropriateness of the recognition of revenue from those transactions. Further to this review, the Company has determined that it will make adjustments to the revenue figures reported in the previously mentioned financial statements periods. Errors have been corrected in the Financial Statements. As a result of these adjustments, the following adjustments were made to the management's discussion and analysis of financial condition and results of operation for the three and twelve months ended December 31, 2021 as previously filed (the "Prior MD&A"):In the "Selected financial Information" sections, revenues and the associated cost of goods sold, inventory, and accounts receivables (as well as the flow-through impacts to gross profit, net income, and other applicable items) were updated due to the review discussed above. Relevant variance explanations were also updated as applicable.In the "Summary of Quarterly Results" sections, revenues and the associated cost of goods sold, inventory, and accounts receivables (as well as the flow-through impacts to gross profit, net income, and other applicable items) were updated due to the review discussed above. Relevant variance explanations were also updated as applicable.In the "Recent Acquisitions" section, acquisitions announced or completed since December 31, 2021 were added or description was modified to reflect recent developments. In the "Litigation" section, description of litigations was updated to reflect changes and developments since December 31, 2021. In the "Restatement" section, description, context and events leading up to the restatement of the financial statements for the three and twelve months ended December 31, 2021 were added. In the "Critical Accounting Estimates – COVID-19 estimation uncertainty" section, language was updated to reflect impact of COVID since December 31, 2021. In the "Management's Annual Report on Internal Controls over Financial Reporting", additional material weaknesses regarding Control Environment and Controls pertaining to Wholesale Revenue identified after the period were added and described as well as remediation status of those additional Material Weaknesses. The Company is also amending Management's Annual Report on Internal Controls over Financial Reporting in this Amendment No. 1, to disclose additional material weaknesses regarding Control Environment and Controls pertaining to Wholesale Revenue identified after the period as well as remediation status of those additional Material Weaknesses. Except as described above, the Annual Report remains unchanged. This Amendment No. 1 does not reflect events occurring after the filing of the Annual Report, or modify or update those disclosures.
