Investments in Equity Securities	INVESTMENTS IN OTHER EQUITY SECURITIES From time to time, the Company may acquire certain equity investments for the promotion of business objectives and these investments are classified as long-term investments and included in “Other long-term assets” in the Condensed Consolidated Balance Sheet. In 2014, the Company acquired a 3.3% interest in Vislink plc (“Vislink”), a U.K. public company listed on the AIM exchange in London, for $3.3 million. The investment in Vislink is being accounted for as a cost method investment as the Company does not have significant influence over the operational and financial policies of Vislink. Since the Vislink investment is also an available-for-sale security, its value is marked to market for the difference in fair value at period end. The carrying value of Vislink was $0.3 million and $0.8 million at March 31, 2017 and December 31, 2016, respectively. Vislink’s accumulated unrealized (loss) gain, net of taxes was $(0.2) million and $0.3 million at March 31, 2017 and December 31, 2016, respectively. During late 2015 through 2016, Vislink’s stock price was below the Company’s cost basis for a prolonged period of time and based on the Company’s assessment, impairment charges of $1.5 million and $1.2 million for Vislink were recorded in the first and third quarter of 2016, respectively, reflecting the new reduced cost basis of the Vislink investment at September 30, 2016. As of December 31, 2016, Vislink’s stock price increased approximately 67% from the stock price as of September 30, 2016. On February 3, 2017, Vislink (from thereon, referred to as Pebble Beach Systems) completed their disposal of its hardware division and changed its name to Pebble Beach Systems. On February 6, 2017, Pebble Beach Systems announced its financial results for fiscal 2016 which showed a significant increase in operating losses. As of March 31, 2017, Pebble Beach System’s stock price had declined 67% from the stock price as of December 31, 2016 and Pebble Beach System is currently seeking alternatives to maximize value for its shareholders, which could include a sale of the company. Since the decline in Vislink’s stock price from December 31, 2016 has been for less than three month, the Company determined that the decline in the fair value of Pebble Beach Systems’ investment is not considered permanent yet and as a result, the $0.5 million loss in Vislink’s investment in the first quarter of 2017 was recorded to other comprehensive loss. The Company’s remaining maximum exposure to loss from the Pebble Beach Systems’ investment at March 31, 2017 was limited to its reduced investment cost of $0.3 million. The assessment as to the nature of a decline in fair value is based on, among other things, the length of time and the extent to which the market value has been less than the Company’s cost basis; the financial condition and near-term prospects of the investment; and the Company’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value. Unconsolidated Variable Interest Entities (“VIE”) In 2014, the Company acquired an 18.4% interest in Encoding.com, Inc. (“EDC”), a video transcoding service company headquartered in San Francisco, California, for $3.5 million by purchasing EDC’s Series B preferred stock. EDC is considered a variable interest entity but the Company determined that it is not the primary beneficiary of EDC. As a result, EDC is accounted for as a cost method investment. The Company determined that there were no indicators existing at March 31, 2017 that would indicate that the EDC investment was impaired. The Company’s maximum exposure to loss from the EDC’s investment at March 31, 2017 was limited to its investment cost of $3.6 million.
