Loss Contingency [Abstract]
Contingencies	Contingencies The Company is subject to various legal proceedings in the ordinary course of its business and in connection with its marketing, distribution and sale of its products. Many of these legal proceedings are in the early stages of litigation and seek damages that are unspecified or not quantified. Although the outcome of these matters cannot be predicted with certainty, the Company does not believe these legal proceedings, individually or in the aggregate, will have a material adverse effect on its consolidated financial condition but could be material to its results of operations for any particular reporting period depending, in part, on its results for that period. (a)Class action complaints relating to restatement On March 11 and 12, 2020, two alleged shareholders of the Company separately filed two putative class action complaints in the U.S. District Court for the Eastern District of New York against the Company and its former Chief Executive Officer (now Executive Chairman) and Chief Financial Officer. The court has consolidated the cases, and the consolidated amended complaint alleges violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder against all defendants, and Section 20(a) of the Exchange Act against the individual defendants. The consolidated amended complaint generally alleges that certain of the Company’s prior public statements about revenues and internal controls were incorrect based on the Company’s March 2, 2020 disclosure that the Audit Committee of the Board was conducting a review of the appropriateness of revenue recognized in connection with certain bulk resin purchases and sales of products through the wholesale channel. The consolidated amended complaint does not quantify a damage request. Defendants moved to dismiss on February 8, 2021. On June 3, 2020, an alleged shareholder filed a Statement of Claim, as amended on August 12, 2020, in the Ontario Superior Court of Justice in Toronto, Ontario, Canada, seeking, among other things, an order certifying the action as a class action on behalf of a putative class of shareholders and damages of an unspecified amount. The Amended Statement of Claim names the Company, its former Chief Executive Officer (now Executive Chairman), Chief Financial Officer, former Chief Financial Officer and Chief Commercial Officer, and current and former members of the Board as defendants and alleges breaches of the Ontario Securities Act, oppression under the Ontario Business Corporations Act and common law misrepresentation. The Amended Statement of Claim generally alleges that certain of the Company’s prior public statements about revenues and internal controls were misrepresentations based on the Company’s March 2, 2020 disclosure that the Audit Committee of the Board was conducting a review of the appropriateness of revenue recognized in connection with certain bulk resin purchases and sales of products through the wholesale channel, and the Company’s subsequent restatement. The Amended Statement of Claim does not quantify a damage request. (b)Regulatory reviews relating to restatement The Company has been responding to requests for information from various regulatory authorities relating to its previously disclosed restatement of its financial statements for the first three quarters of 2019. The Company is responding to all such requests for information and cooperating with all regulatory authorities. The Company cannot predict the outcome of any such regulatory review or investigation and it is possible that additional investigations or one or more formal proceedings may be commenced against the Company and its current and former officers and directors in connection with these regulatory reviews and investigations. (c)Litigation relating to marketing, distribution and sale of products On June 16, 2020, an alleged consumer filed a Statement of Claim on behalf of a class in the Court of Queen’s Bench of Alberta in Alberta, Canada, against the Company and other Canadian cannabis manufacturers and/or distributors. On December 4, 2020, a Third Amended Statement of Claim was filed, which added a second alleged consumer. The Third Amended Statement of Claim alleges claims related to the defendants’ advertised content of cannabinoids in cannabis products for medicinal use on or after June 16, 2010 and cannabis products for adult use on or after October 17, 2018. The Third Amended Statement of Claim seeks a total of C$500 million for breach of contract, compensatory damages, and unjust enrichment or such other amount as may be proven in trial and C$5 million in punitive damages against each defendant, including the Company. The Third Amended Statement of Claim also seeks interest and costs associated with the action. The Company has not responded to the Third Amended Statement of Claim. A number of claims, including purported class actions, have been brought in the U.S. against companies engaged in the U.S. hemp business alleging, among other things, violations of state consumer protection, health and advertising laws. On April 8, 2020, a putative class action complaint was filed in the U.S. District Court for the Central District of California against Redwood, alleging violations of California’s Unfair Competition Law, False Advertising Law, Consumers Legal Remedies Act, and breaches of the California Commercial Code for breach of express warranties and implied warranty of merchantability with respect to Redwood’s marketing and sale of U.S. hemp products. The complaint did not quantify a damage request. On April 10, 2020, the class action complaint was dismissed for certain pleading deficiencies and the plaintiff was granted leave until April 24, 2020 to amend the complaint to establish federal subject matter jurisdiction. On April 28, 2020, the action was dismissed without prejudice for failure to prosecute and for failure to comply with a court order. As of the date of this Annual Report, the plaintiff has not refiled the complaint.
