Investments, Debt and Equity Securities [Abstract] |
Investments | Investments On September 12, 2018, we invested $54 million in Shift Technologies, Inc., a San Francisco-based digital retailer, in exchange for Series D convertible preferred stock. We have determined that our investment in Shift does not meet the criteria for a variable interest entity, and we do not have control or significant influence over Shift. As a result, we currently recorded a cost method investment within other non-current assets on our Consolidated Balance Sheet as of March 31, 2019. As of March 31, 2019, there were no identified events or changes in circumstances that would have a significant effect on the value of the investment. We did not record any impairment charges associated with this investment in the three-month period ended March 31, 2019.
