BASIS OF PRESENTATION Business and organization As used herein, "Overstock," "Overstock.com," "O.co," "we," "our" and similar terms include Overstock.com, Inc. and our majority-owned subsidiaries, unless the context indicates otherwise. We were formed on May 5, 1997 as D2-Discounts Direct, a limited liability company. On December 30, 1998, we were reorganized as a C Corporation in the State of Utah and reincorporated in Delaware in May 2002. On October 25, 1999, we changed our name to Overstock.com, Inc. We are an online retailer and advancer of blockchain technology. Through our online retail business, we offer a broad range of price-competitive products, including furniture, home decor, bedding and bath, and housewares, among other products. We sell our products and services through our Internet websites located at www.overstock.com, www.o.co and www.o.biz (referred to collectively as the "Website"). Although our three websites are located at different domain addresses, the technology, equipment, and processes supporting the Website and the process of order fulfillment described herein are the same for all three websites. In late 2014, we began working on initiatives to develop and advance blockchain technology, which initiatives we refer to collectively as Medici. Our Medici business initiatives seek to leverage the security, transparency and immutability of cryptographically protected and distributed ledgers, such as blockchains, and are focused on solving important problems, including financial transaction issues, particularly in the area of securities settlement. Our Medici business initiatives include our wholly-owned subsidiary, Medici Ventures, Inc. ("Medici Ventures"), which conducts a majority of its business through its majority-owned subsidiary tZERO Group, Inc. ("tZERO"), formerly t.com, Inc., a financial technology company pursuing potential financial applications of blockchain technologies as well as non-blockchain businesses. Medici Ventures currently holds equity interests in several technology companies whose focuses include commercial blockchain applications for identity and social media, property and land, money and banking, capital markets, supply chain, and voting. In December 2017 we engaged Guggenheim Securities, LLC to help us identify and evaluate certain strategic initiatives. We are considering a range of potential transactions, including a sale of our retail business and additional equity or debt financings. Our Board continually discusses a variety of potential strategic and financial options and other changes to our business, but has not approved or made any determination to consummate any strategic transaction, and may choose not to do so in the foreseeable future or at all. Basis of presentation We have prepared the accompanying consolidated financial statements pursuant to generally accepted accounting principles in the United States ("GAAP"). Preparing financial statements requires us to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and accompanying disclosures. Although these estimates are based on our best knowledge of current events and actions that we may undertake in the future, our actual results may be different from our estimates. The results of operations presented herein are not necessarily indicative of our results for any future period. In the fourth quarter of 2018, we completed our annual review of our segment reporting and in light of a strategic shift in our Chief Operating Decision Maker's long-term strategic focus for our organization, we no longer consider the split of retail direct and retail partner as a distinct and relevant measure of our business. Accordingly, revenues and cost of goods sold recorded in "Direct" and "Partner and Other" are now split between "Retail" and "Other" on the consolidated statements of operations. "Retail" includes retail revenue and costs of goods sold from both "Direct" and "Partner" transactions. Our revenues and costs of goods sold related to our Medici business remains in "Other". In addition, we have recast the prior period revenues and cost of goods sold to conform with current year presentation. Direct and Partner are no longer considered separate reportable segments in our Business Segment disclosures. In addition, tZERO has been identified as a reportable segment separate from Other. For purposes of comparability, we reclassified other certain immaterial amounts in the prior periods presented to conform with the current year presentation. We also retrospectively applied certain accounting standard updates as discussed in Note 2Accounting Policies, Recently adopted accounting standards .
