[1] | A history of operating losses in recent years has led to uncertainty with respect to the Company’s ability to realize certain net deferred tax assets. In 2015, the Company recorded a valuation allowance against all of its U.S. net deferred tax assets, resulting in an increase in valuation allowance of $3.1 million in the fourth quarter of 2015. This increase in valuation allowance is offset partially by the release of $0.9 million valuation allowance against one of its Israel subsidiaries due to cumulative income generated in recent years. In the fourth quarter of 2016, the Company recorded an additional valuation allowance of $18.3 million against all of the United States deferred tax assets as well as its net operating losses generated in 2016. This increase in valuation allowance is offset partially by the release of $8.4 million of valuation allowance associated with the TVN French Subsidiary. Due to a change in its business model, as of December 31, 2016, the TVN French Subsidiary is forecasted to generate pretax income in future periods.
[2] | In 2016, as part of the TVN integration plan, the Company established the TVN VDP to enable the French employees of TVN to voluntarily terminate with certain benefits. The plan was approved by the applicable French authorities and a total of 83 employees applied for the TVN VDP and were duly approved by the Company in the fourth quarter of 2016. Based on the applicable accounting guidance, the Company recorded a charge of $13.1 million for TVN VDP in the fourth quarter of 2016. This charge is offset partially by a $2.0 million pension curtailment gain. (See Note 11, “Restructuring and related charges-TVN VDP,” of the notes to the Consolidated Financial Statements for additional information on the TVN VDP and pension curtailment gain).
[3] | On February 29, 2016, the Company completed the acquisition of TVN and applied the acquisition method of accounting for the business combination. The selected quarterly financial data for the year ended December 31, 2016 of the combined entity includes 10 months of operating results of TVN beginning March 1, 2016.
[4] | In the first and third quarter of 2016, the Company recorded impairment charges of $1.5 million and $1.2 million, respectively, for its investment in Vislink. In the first quarter of 2015, the Company recorded an impairment charge of $2.5 million for its investment in VJU. These impairment charges were recorded as a result of the Company’s assessment which concluded that their impairment were on an other-than-temporary basis. (See Note 5, “Investments in Other Equity Securities,” of the notes to the Consolidated Financial Statements for additional information).
