Commitments And Contingencies Disclosure [Abstract]
Commitment and Contingencies	12. COMMITMENT AND CONTINGENCIES Inventory Purchases—As of December 31, 2021 and 2022, the Company had $32.3 million and $13.5 million, respectively, of inventory purchase orders placed with vendors waiting to be fulfilled. Sales or Other Similar Taxes—Based on the location of the Company’s current operations, the majority of sales tax is collected and remitted either by the Company or on its behalf by e-commerce marketplaces in most states within the U.S. To date, the Company has had no actual or threatened sales and use tax claims from any state where it does not already claim nexus or any state where it sold products prior to claiming nexus. However, the Company believes that the likelihood of incurring a liability as a result of sales tax nexus being asserted by certain states where it sold products prior to claiming nexus is probable. As of each of December 31, 2021 and December 31, 2022, the Company estimates that the potential liability, including current sales tax payable is approximately $0.7 million which has been recorded as an accrued liability. The Company believes this is the best estimate of an amount due to taxing agencies, given that such a potential loss is an unasserted liability that would be contested and subject to negotiation between the Company and the state, or decided by a court. Settlement Agreement—On May 2, 2021, the Company entered into a settlement agreement with one of the Company’s suppliers who agreed to pay the amount of $3.0 million to the Company in three installments of $1.0 million each, with the first payment to be paid on or before May 31, 2021, the second payment to be paid on or before September 30, 2021, and the third payment to be paid on or before November 30, 2021. Further, the supplier agreed to deliver certain goods as part of this settlement by September 30, 2021. Through the date of the accompanying Consolidated Financial Statements, the supplier has not paid in full its required first payment of $1.0 million nor has it delivered the required quantity of goods. The Company fully reserved $4.1 million within prepaid and other current assets on its Consolidated Financial Statements during the year-ended December 31, 2021 and December 31, 2022. The Company has commenced legal action against the supplier and certain other parties to the matter. One of the parties to the matter has filed for bankruptcy and such legal action is being stayed until the resolution of such bankruptcy. The Company continues to reserve its legal options and rights on this matter as of December 31, 2022. Legal Proceedings—The Company is party to various actions and claims arising in the normal course of business. The Company does not believe that the final outcome of these matters will have a material adverse effect on the Company’s financial position or results of operations. In addition, the Company maintains what it believes is adequate insurance coverage to further mitigate risk. However, no assurance can be given that the final outcome of such proceedings will not materially impact the Company’s financial condition or results of operations. Further, no assurance can be given that the amount or scope of existing insurance coverage will be sufficient to cover losses arising from such matters. Securities Class Action—Following a mediation, an initial settlement-in-principle, and further negotiations, on April 22, 2022, the Company, in conjunction with its codefendants Yaniv Sarig, Fabrice Hamaide, and Arturo Rodriguez, entered into a formal settlement agreement to resolve the purported class action lawsuits filed in the U.S. District Court for the Southern District of New York (the “Court”) by Andrew Tate on May 13, 2021, and by Jeff Coon, on June 10, 2021, consolidated under the caption Tate v. Aterian, Inc., et. al., 21-cv-04323-VM (the “Action”). In the Action, plaintiffs claimed that defendants made false and materially misleading statements and failed to disclose material adverse facts regarding the Company’s business, operations, and prospects, and that this was revealed on May 4, 2021, in a report issued by Culper Research. The Company and its codefendants denied, and continue to deny, that these allegations have any merit. The settlement agreement contains no admission of wrongdoing and expressly states that the Company and its codefendants have entered into a settlement solely to avoid the uncertainties, burden, and expense of further litigation. The settlement class consists of purchasers of the Company’s securities during the period from August 24, 2020, through May 3, 2021, inclusive (the “Class Period”). Under the terms of the proposed settlement, members of the settlement class release the Company and its codefendants from, among other things, all claims and causes of action of every nature and description, whether known or unknown, that were asserted in the Action; could have been asserted in the Action; relate in any way to transactions in the Company’s securities during the Class Period and any facts, transactions, or occurrences referred to in any of the pleadings or other documents filed in the Action. Under the agreement, the Company was to pay $1.3 million, within 10 business days of the Court’s preliminary approval of the settlement, which would, after final court approval, be distributed to claimants in the settlement class pursuant to the plan of allocation filed with the Court on May 4, 2022. To the extent permitted by the Court, this payment will also fund the legal fees of plaintiffs’ counsel and the costs of administering the settlement. The proposed settlement was preliminarily approved by the Court on May 6, 2022, and the Company thereafter paid $1.3 million into the designated escrow. On September 12, 2022, the Court entered a final judgment approving the class action settlement. The claims administrator is in the process of distributing funds to claimants. The Company does not anticipate any further action in this matter. In connection with the settlement, the Company accrued approximately $1.3 million during the year ended December 31, 2021 and paid approximately $1.3 million in the second quarter of 2022. Shareholder Derivative Actions Related to the Securities Class Action—On October 21, October 25 and November 10, 2021, three shareholder derivative actions were filed on behalf of the Company by Shaoxuan Zhang, Michael Sheller and Tyler Magnus in the U.S. District Court for the Southern District of New York. These actions, collectively, name Yaniv Sarig, Fabrice Hamaide, Arturo Rodriguez, Greg B. Petersen, Bari A. Harlam, Amy von Walter, William Kurtz, Roi Zion Zahut, Joseph A. Risico, Tomer Pascal and Mihal Chaouat-Fix as individual defendants, and the Company as a nominal defendant. These actions are predicated on substantively the same factual allegations contained in the above-described securities class action which was resolved via settlement in September 2022 The Company believes the allegations are without merit and continues to deny each of the claims and allegations of wrongdoing. On December 12, 2022, the parties reached an agreement and entered into a Stipulation and Agreement of Settlement (the “Stipulation”) to resolve this derivative action. Under the Stipulation, the Company agreed to adopt certain corporate governance reforms, the terms of which are outlined in Exhibit A to the Stipulation, and a payment of the Plaintiffs’ attorneys’ fees and expenses of $0.3 million The proposed settlement was preliminarily approved by the Court on December 29, 2022, the Company made the agreed $0.3 million payment, and a hearing to determine whether the Court should give final approval to the settlement is scheduled for March 2023. Investor Contract Action—On September 20, 2021, Sabby Volatility Warrant Master Fund Ltd. (the “Investor”) sued the Company in the Supreme Court of the State of New York, New York County, alleging that the Company breached the Securities Purchase Agreement, dated June 10, 2021 (the “Purchase Agreement”), pursuant to which the Investor purchased 400,000 shares of the Company’s common stock, for an aggregate price of approximately $6.0 million. The Investor contended that certain of the representations and warranties made by the Company in the Purchase Agreement concerning its financial condition and the accuracy of its prior disclosures were untrue and that the Company breached the Purchase Agreement’s anti-dilution and use-of-proceeds covenants on both August 9, 2021 and September 23, 2021, when the Company resolved certain defaults with High Trail. The parties reached a settlement agreement for $1.6 million. In this action, the Company denied, and it continues to deny, the Investor’s allegations, and the settlement agreement contains no admission of wrongdoing; the Company nevertheless determined that a resolution was warranted to minimize the costs and risks of ongoing litigation. The Company recorded a $1.6 million expense in general and administrative expenses on the Consolidated Statement of Operations for the year-ended December 31, 2022. Mueller Action—In October 2021, the Company received a class action notification and pre-lawsuit demand letter demanding corrective action with respect to the marketing, advertising and labeling of certain products under the Mueller brand (the “Mueller Action”). In April 2022, the parties reached an agreement in principle to resolve this potential action for $0.5 million in cash and $0.3 million worth of coupons, which the Company accrued $0.8 million in the three months ended March 31, 2022, subject to negotiation and the execution of final settlement documents and court approval. If that process does not succeed, the Company is prepared to continue the full defense of this action. Sentia Wellness Action—On June 7, 2022, Sentia Wellness Inc. (“Sentia”) filed an action in Multnomah County, Oregon against Boris Jordan; Measure 8 Ventures, LP; Gron Ventures Fund I, LP; Zola Global Investors Ltd.; Anson Advisors Inc.; AC Anson Investments Ltd.; Anson Investments Master Fund LP; Anson Opportunities Master Fund LP; Serendipity SPC -Trimble Fund SP; Lapid Us Investments LLC; Hadron Healthcare and Consumer Special Opportunities Master Fund; Alliance Global Partners LLC; Sunny Puri; Juan Martinez; Peter Clateman; Wilder Ramsey; Gregory Crowe; Igor Gimelshtein; Tarik Ouass; Andrea Oriani; Marco D’attanseo; Afzal Hasan; and the Company. Sentia asserts claims for breach of fiduciary duty, breach of duty of good faith and fair dealing, intentional interference with prospective economic relations, intentional interference with contractual relationship, negligent misrepresentation, and unjust enrichment against various of these defendants, based on the allegation that Sentia’s debt holders conspired to take control of Sentia and direct its resources and acquisition efforts to the debt holders’ individual financial interests. Sentia alleges that Aterian—then known as Mohawk —contemplated a partial acquisition of Sentia that played some role in these events. The Company filed a motion to dismiss the action and, in response, on December 8, 2022, counsel for Sentia agreed to dismiss the Company from the action (without prejudice). Earn-out Payment Dispute—On February 24, 2022, the Company received a notice disputing the Company’s calculation of the earn-out payment to be paid to Josef Eitan and Ran Nir pursuant to the Stock Purchase Agreement (the “PPD Stock Purchase Agreement”), dated as of May 5, 2021, by and among the Company, Truweo, LLC, Photo Paper Direct Ltd, Josef Eitan and Ran Nir. The Company is in discussions with representatives of Mr. Eitan and Mr. Nir, who believe they are entitled to the full earn-out under the terms of the PPD Stock Purchase Agreement, whereas the Company believes they are not. Mr. Eitan and Mr. Nir filed a motion to compel arbitration in the Southern District of New York on September 14, 2022. The Company filed its motion to oppose such motion on October 28, 2022, believes its calculations are accurate and intends to vigorously defend itself.
