Equity Method Investments and Joint Ventures [Abstract] |
Equity Method Investment | Equity Method Investment Investment in eREX Spark Marketing Co., Ltd In September 2015, the Company and Spark HoldCo, together with eREX Co., Ltd., a Japanese company, entered into an agreement ("eREX JV Agreement") to form a new joint venture, eREX Spark Marketing Co., Ltd ("eREX Spark"). As part of this agreement, the Company made contributions of 156.4 million Japanese Yen, or $1.4 million, for 20% ownership of eREX Spark. The Company is entitled to share in 30% of the dividends distributed by eREX Spark for the first year a qualifying dividend is paid and for the subsequent four years thereafter. After this period, dividends will be distributed proportionately with the equity ownership of eREX Spark. eREX Spark's board of directors consists of four directors, one of whom is appointed by the Company. Based on the Company's significant influence, as reflected by the 20% equity ownership and 25% control of the eREX Spark board of directors, we recorded the investment in eREX Spark as an equity method investment. Our investment in eREX Spark was $2.3 million as of December 31, 2016, reflecting contributions made by the Company through December 31, 2016 and our proportionate share of earnings as determined under the HLBV method as of December 31, 2016, and recorded in other assets in the consolidated balance sheet. There were no basis differences between our initial contribution and the underlying net assets of eREX Spark. We recorded our proportionate share of eREX Spark's earnings of $0.9 million in our combined and consolidated statement of operations for the year ended December 31, 2016.
