Investments	SaleMove In September 2013, the Company entered into a Convertible Note Purchase Agreement with SaleMove in which AutoWeb invested $150,000 in SaleMove in the form of an interest bearing, convertible promissory note. In November 2014, the Company invested an additional $400,000 in SaleMove in the form of an interest bearing, convertible promissory note. Upon closing of a preferred stock financing by SaleMove in July 2015, these two notes were converted in accordance with their terms into an aggregate of 190,997 Series A Preferred Stock, which shares are classified as a long-term investment on the consolidated balance sheet as of December 31, 2016. The Company recorded an impairment charge of $0.6 million in SaleMove in 2017. On June 5, 2018, the Company sold its shares of Series A Preferred stock back to SaleMove for $125,000. The gain of $125,000 is recorded in Interest and other income (expense) on the Consolidated Statement of Operations for year ended December 31, 2018. In October 2013, the Company entered into a Reseller Agreement with SaleMove to become a reseller of SaleMove’s technology for enhancing communications with consumers. SaleMove’s technology allows Dealers and Manufacturers to enhance the online shopping experience by interacting with consumers in real-time, including live video, audio and text-based chat or by phone. The Company and SaleMove equally share in revenues from automotive-related sales of the SaleMove products and services. In connection with this reseller arrangement, the Company advanced $1.0 million to SaleMove to fund SaleMove’s 50% share of various product development, marketing and sales costs and expenses. These previously advanced funds are repaid to the Company from SaleMove’s share of net revenues and expenses from the Reseller Agreement each reporting period. During the three months ended September 30, 2018, the Company performed a qualitative review of the agreement with SaleMove and, based on several factors related to the trend in operating results from this reseller arrangement and costs being incurred by the Company, the parties agreed to allow the arrangement to expire November 30, 2018, one month earlier than the original expiration date of December 31, 2018. Upon expiration of the Reseller Agreement, the remaining outstanding advances are no longer recoverable from SaleMove, and, accordingly, the Company has impaired the remaining balance of $364,000 of advances due from SaleMove. The impairment charge is included in “Long-lived asset impairment” in the Consolidated Statement of Operations for the year ended December 31, 2018. GoMoto In December 2014, the Company entered into a Series Seed Preferred Stock Purchase Agreement with GoMoto in which the Company paid $100,000 for 317,460 shares of Series Seed Preferred Stock, $0.001 par value per share. The $100,000 investment in GoMoto was recorded at cost because the Company does not have significant influence over GoMoto. In October 2015 and May 2016, the Company invested an additional $375,000 and $375,000 in each period in the form of convertible promissory notes (“GoMoto Notes”). The GoMoto Notes accrue interest at an annual rate of 4.0% and are due and payable in full upon demand by the Company or at GoMoto’s option ten days’ written notice unless converted prior to the repayment of the GoMoto Notes. The GoMoto Notes will be converted into preferred stock of GoMoto in the event of a preferred stock financing by GoMoto of at least $1.0 million prior to repayment of the GoMoto Notes. At December 31, 2018 and 2017, both the GoMoto Notes and related interest receivable are fully reserved on the Consolidated Condensed Balance Sheets because the Company believed the amounts were not recoverable. Further, the three months ended September 30, 2018, represented the third consecutive quarter of declining operating results for GoMoto and, as such, the Company performed a qualitative review of its investment in GoMoto. Based on continuing deterioration in GoMoto’s financial position, the Company believed that uncertainty existed in the recoverability of its remaining investment of $100,000 in GoMoto and, accordingly, recognized a loss on the investment which has been recorded in “Interest and other income (expense)” on the Consolidated Statement of Operations for the year ended December 31, 2018. On January 29, 2019, the GoMoto Notes were converted into 1,781,047 shares of GoMoto’s Series A-2 Preferred Stock, $0.001 par value per share. The outstanding principal plus accrued interest under the GoMoto Notes was converted in accordance with the terms of the notes upon the closing of a new preferred stock financing and based on a discount to the price paid by the new investor for the investor’s preferred shares. On July 30, 2019, the Company entered into a Repurchase Agreement with GoMoto, pursuant to which GoMoto repurchased these 317,460 shares of Series Seed Preferred Stock and 1,781,047 shares of Series A-2 Preferred Stock from the Company for an aggregate purchase price of $250,000.
