Commitments and Contingencies	16.Commitments and Contingencies Securities Class Action and Derivative Matters In March 2019, two substantially identical class action complaints alleging violations of the federal securities laws were filed by individual shareholders against the Company, certain of the Company’s current officers and the Company’s former controlling shareholder, Artal Group S.A. (“Artal”), in the United States District Court for the Southern District of New York. The actions were consolidated and lead plaintiffs were appointed in June 2019. A consolidated amended complaint was filed on July 29, 2019, naming as defendants the Company, certain of the Company’s current officers and directors, and Artal and certain of its affiliates. A second consolidated amended complaint was filed on September 27, 2019. The operative complaint asserted claims on behalf of all purchasers of the Company’s common stock between May 4, 2018 and February 26, 2019, inclusive (the “Class Period”), including purchasers of the Company’s common stock traceable to the May 2018 secondary offering of the Company’s common stock by certain of its shareholders. The complaint alleged that, during the Class Period, the defendants disseminated materially false and misleading statements and/or concealed or recklessly disregarded material adverse facts. The complaint alleged claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 thereunder, and with respect to the secondary offering, under Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended. The plaintiffs sought to recover unspecified damages on behalf of the class members. The Company filed a motion to dismiss the complaint on October 31, 2019. On November 30, 2020, the Court granted the Company’s motion to dismiss in full and dismissed the complaint. The plaintiffs did not appeal. Between March and July 2019, the Company received shareholder litigation demands alleging breaches of fiduciary duties by certain current and former Company directors and executive officers, to the alleged injury of the Company. The allegations in the demands related to those contained in the dismissed securities class action litigation. In response to the demands, pursuant to Virginia law, the Board of Directors created a special committee to investigate and evaluate the claims made in the demands. In addition, four derivative complaints were filed, each making allegations against certain of the Company’s officers and directors and/or Artal and certain of its affiliates. First, on June 13, 2019, a shareholder derivative complaint was filed in the Southern District of New York against certain of the Company’s officers and directors alleging, among other things, that the defendants breached fiduciary duties to the alleged injury of the Company. The plaintiff voluntarily dismissed the complaint on July 8, 2019 and the Company agreed to treat the complaint as a litigation demand. Second, on July 23, 2019, another shareholder derivative complaint was filed in the Southern District of New York against certain of the Company’s officers and directors alleging, among other things, that the defendants breached fiduciary duties to the alleged injury of the Company. The plaintiff voluntarily dismissed the complaint the same day. Third, on October 25, 2019, another shareholder derivative complaint was filed in the Southern District of New York against certain of the Company’s officers and directors alleging, among other things, that the defendants breached fiduciary duties to the alleged injury of the Company. Finally, on December 16, 2019, a shareholder derivative complaint was filed in New York Supreme Court against certain of the Company’s officers and directors, and Artal and certain of its affiliates, alleging, among other things, that the defendants breached fiduciary duties to the alleged injury of the Company. This action and the derivative action filed October 25, 2019 (collectively, the “Derivative Actions”) were initially stayed pending a decision on the defendants’ motion to dismiss the securities class action, and all parties agreed to an additional stay until June 24, 2021. On June 24, 2021, the parties to the Derivative Actions jointly notified the Southern District of New York and the New York Supreme Court that the parties reached an agreement-in-principle to resolve the Derivative Actions. Subsequently, on August 17, 2021, the parties to the Derivative Actions jointly filed the formal Stipulation of Settlement as well as the Proposed Order and Final Judgment in New York Supreme Court. On November 30, 2021, the New York Supreme Court entered the Order and Final Judgment, and on January 7, 2022, the Southern District of New York entered a dismissal order. The time to appeal the Order and Final Judgment and the dismissal of the October 25, 2019 federal derivative action has passed. Federal Trade Commission Matter The Company received a letter from the U.S. Federal Trade Commission (the “FTC”) dated September 3, 2019, advising that the FTC was conducting a non-public inquiry into the practices of the Company's wholly owned subsidiary Kurbo, Inc. (“Kurbo”) relating to the collection, use, disclosure and sharing of personal information. Kurbo offers a paid private coaching service as well as a free app to help families teach children healthy habits. The FTC focused on whether certain practices in the Kurbo free app complied with the Children's Online Privacy Protection Act ("COPPA"). On February 16, 2022, the FTC filed a complaint and proposed settlement order in the United States District Court for the Northern District of California to resolve allegations that Kurbo violated COPPA by failing to provide required notices and obtain verifiable parental consent prior to collecting, using, and disclosing personal information from children using the Kurbo app. In connection with the proposed settlement, Kurbo and the Company are required, among other things: (i) to update their procedures to ensure that they obtain verifiable parental consent before collecting personal information from children, (ii) to destroy all of the personal information they may have obtained without verifiable parental consent as well as any models or algorithms based on that information, (iii) to update their records retention policy to require destruction of user information one year after a child stops tracking in the Kurbo app, and (iv) to pay a civil penalty of $1,500. Kurbo and the Company deny all of the material allegations in the FTC complaint and deny that either Kurbo or the Company ever violated COPPA or otherwise engaged in any wrongdoing. They entered into the settlement solely to resolve the matter and avoid the expense of litigation. The settlement will become final when the court enters the Consent Order. Other Litigation Matters Due to the nature of the Company’s activities, it is also, at times, subject to other pending and threatened legal actions that arise out of the ordinary course of business. In the opinion of management, the disposition of any such matters is not expected, individually or in the aggregate, to have a material adverse effect on the Company’s results of operations, financial condition or cash flows. However, the results of legal actions cannot be predicted with certainty. Therefore, it is possible that the Company’s results of operations, financial condition or cash flows could be materially adversely affected in any particular period by the unfavorable resolution of one or more legal actions. Commitments Minimum commitments under non-cancelable purchase obligations at January 1, 2022 were $18,861, of which $9,378 is due in fiscal 2022, $7,544 is due in fiscal 2023 and the remaining $1,939 is due in fiscal 2024.
