Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal proceedings and contingencies From time to time, we are involved in litigation concerning consumer protection, employment, intellectual property, claims under the securities laws, and other commercial matters related to the conduct and operation of our business and the sale of products on our Website. In connection with such litigation, we have been in the past and we may be in the future subject to significant damages. In some instances, other parties may have contractual indemnification obligations to us. However, such contractual obligations may prove unenforceable or non-collectible, and if we cannot enforce or collect on indemnification obligations, we may bear the full responsibility for damages, fees, and costs resulting from such litigation. We may also be subject to penalties and equitable remedies that could force us to alter important business practices. Such litigation could be costly and time consuming and could divert or distract our management and key personnel from our business operations. Due to the uncertainty of litigation and depending on the amount and the timing, an unfavorable resolution of some or all of such matters could materially affect our business, results of operations, financial position, or cash flows. The nature of the loss contingencies relating to claims that have been asserted against us are described below. On September 23, 2009, SpeedTrack, Inc. sued us along with 27 other defendants in the United States District Court in the Northern District of California. We are alleged to have infringed a patent covering search and categorization software. We believe that certain third-party vendors of products and services sold to us are contractually obligated to indemnify us, and we have tendered defense of the case to an indemnitor who accepted the defense. On April 21, 2016, the court entered an order partially dismissing the claims against us. On May 4, 2016, the plaintiff filed an amended complaint, and we filed our answer. No estimate of the possible loss or range of loss can be made. We intend to vigorously defend this action and pursue our indemnification rights with our vendors. In June 2013, William French ("French") and the State of Delaware ("Delaware") sued us, along with numerous other defendants, in the Superior Court of the State of Delaware for alleged violations of Delaware's unclaimed property laws. French and Delaware alleged that we knowingly refused to fulfill obligations under Delaware's Abandoned Property Law by failing to report and deliver unclaimed gift card funds to the State of Delaware, and knowingly made, used or caused to be made or used, false statements and records to conceal, avoid or decrease an obligation to pay or transmit money to Delaware in violation of the Delaware False Claims and Reporting Act. On June 28, 2019, the court entered a judgment against us in the amount of approximately $7.3 million (for certain unredeemed gift card balances, treble damages, and penalties) as a result of a jury verdict which was returned September 20, 2018. On October 23, 2019, the court entered an award of attorneys' fees and costs of $1.3 million and entered final judgment in the amount of $8.6 million. We have commenced an appeal and filed our appellate brief. Our estimated liability for these amounts was included in Accrued liabilities at December 31, 2019. The expense associated with these litigation charges was included in general and administrative expense in our consolidated statement of operations for the year ended December 31, 2018. In February 2018, the Division of Enforcement of the SEC informed tZERO and subsequently informed us that it is conducting an investigation and requested that we and tZERO voluntarily provide certain information and documents related to tZERO and the tZERO security token offering in connection with its investigation. In December 2018, we received a follow-up request from the SEC relating to its investigation. As previously disclosed, on October 7, 2019, we received a subpoena from the SEC requesting documents related to the Dividend we announced to stockholders in June 2019 and requesting 10b-5-1 plans of our officers and directors that were in effect during the period of January 1, 2018 through October 7, 2019. On December 9, 2019, we received a subpoena from the SEC requesting documents related to the GSR transaction and the alternative trading system run by tZERO ATS, LLC, formerly known as Pro Securities, LLC. On December 19, 2019, we received a subpoena from the SEC requesting our insider trading policies as well as certain employment and consulting agreements. We have also previously received requests from the SEC regarding our communications with our former chief executive officer and director, Patrick Byrne and the matters referenced in the December 2019 subpoenas. We are in regular, active communication with the SEC and are cooperating fully with it in connection with its investigations and information requests. tZERO's broker-dealer subsidiaries are subject to extensive regulatory requirements under federal and state laws and regulations and self-regulatory organization ("SRO") rules. Each of SpeedRoute LLC ("SpeedRoute") and tZERO ATS, LLC is registered with the SEC as a broker-dealer under the Securities Exchange Act of 1934 ("Exchange Act") and in the states in which it conducts securities business and is a member of FINRA and other SROs (as applicable). In addition, tZERO ATS, LLC owns and operates an alternative trading system registered with the SEC. Each of SpeedRoute and tZERO ATS, LLC is subject to regulation, examination, investigation, and disciplinary action by the SEC, FINRA, and state securities regulators, as well as other governmental authorities and SROs with which it is registered or licensed or of which it is a member. Moreover, as a result of tZERO's projects seeking to apply distributed ledger technologies to the capital markets, tZERO's subsidiaries have been, and remain involved in, ongoing oral and written communications with regulatory authorities. As previously disclosed, tZERO's broker-dealer subsidiaries are currently undergoing various examinations, inquiries, and/or investigations undertaken by various regulatory authorities, which may result in financial and other settlements or penalties. Any significant failure by tZERO's broker-dealer subsidiaries to satisfy regulatory authorities that they are in compliance with all applicable rules and regulations could have a material adverse effect on tZERO and on us. In addition, a further tZERO subsidiary, tZERO Markets, LLC ("tZERO Markets"), has applied for and is in process of seeking regulatory approvals to operate as a broker-dealer in a variety of areas, including retail activities. The approval process involves satisfying the regulatory authorities that tZERO Markets can operate in the manner it proposes and, in addition, if approval is granted, tZERO Markets will be subject to a number of legal and regulatory requirements, some of which will be new to tZERO's broker-dealer subsidiaries. tZERO's subsidiary, tZERO Crypto, Inc., formerly known as Bitsy, Inc., is registered as or is applying to become a money transmitter (or its equivalent) in many states and is subject to extensive regulatory requirements applicable to money services businesses, including the requirements of the Financial Crimes Enforcement Network of the U.S. Department of the Treasury ("FinCEN"), anti-money laundering requirements, know-your-customer requirements, record-keeping, reporting and capital and bonding requirements, and inspection by state and federal regulatory agencies. Compliance with these requirements requires the dedication of significant resources and any material failure by tZERO Crypto, Inc. to remain in compliance with the applicable regulatory requirements could subject it to liability or limit the services it may offer. On September 27, 2019, a purported securities class action lawsuit was filed against us and our former chief executive officer and former chief financial officer in the United States District Court in the Central District of Utah, alleging violations under Section 10(b), Rule 10b-5, Section 20(a), Section 20(A) of the Exchange Act. On October 8, 2019, October 17, 2019, October 31, 2019, and November 20, 2019, four similar lawsuits were filed in the same court also naming the Company and the above referenced former executives as defendants, bringing similar claims under the Exchange Act, and seeking similar relief. These cases were consolidated into a single lawsuit on December 19, 2019. No estimates of the possible losses or range of losses can be made at this time. We intend to vigorously defend this consolidated action. On November 22, 2019, a shareholder derivative suit was filed against us and certain past and present directors and officers of the Company in the United States District Court for the District of Delaware, with allegations that include: (i) breach of fiduciary duties, (ii) unjust enrichment, (iii) insider selling and misappropriation of the company's information, and (iv) contribution under Sections 10(b) and 21D of the Exchange Act. On December 17, 2019, a similar lawsuit was filed in the same court, naming the same defendants, bringing similar claims, and seeking similar relief. No estimates of the possible losses or range of losses can be made at this time. We intend to vigorously defend these actions. We establish liabilities when a particular contingency is probable and estimable. At December 31, 2019 and 2018, we have accrued $9.6 million and $10.3 million, respectively, which are included in accrued liabilities in our consolidated balance sheets. It is reasonably possible that the actual losses may exceed our accrued liabilities.
