[1] As of December 31, 2016, the Company’s TVN French Subsidiary had an aggregate of $17.9 million of loans due to various financing programs of French government agencies, $14.7 million of which is related to loans backed by R&D tax credit receivables. As of December 31, 2016, the TVN French Subsidiary had an aggregate of $25.7 million of R&D tax credit receivables from the French government from 2017 through 2020. (See Note 10, “Certain Balance Sheet Components-Prepaid expenses and other current assets,” for more information). These tax loans have a fixed rate of 0.6%, plus EURIBOR 1 month plus 1.3% and matures between 2017 through 2019. The remaining loans of $3.3 million at December 31, 2016 primarily relates to financial support from French government agencies for R&D innovation projects at minimal interest rates and these loans mature between 2020 through 2023.

[2] One of the term loans with a certain financial institution contains annual covenants that require the TVN French Subsidiary to maintain a minimum working capital balance and various other financial covenants and restrictions that limit the French Subsidiary’s ability to incur additional indebtedness. The annual covenant is based on French statutory year-end results and the TVN French Subsidiary failed the 2016 covenant test primarily due to the Company’s plan to integrate TVN’s operations into other subsidiaries for tax planning and logistic purpose. The Company has informed the financial institution of the 2016 covenant test results and has made plans to pay off the entire loan balance of approximately $0.4 million in early 2017 and as a result, the entire loan balance is recorded under “Other debts and capital lease obligations, current,” in the Consolidated Balance Sheets.

[3] The TVN French Subsidiary obtained advances under a credit line with BPI France against a pool of eligible receivables with recourse.

This credit line was renewed in July 2016 for an additional year with no material change to the terms of the credit agreement. There was no balance outstanding to BPI France as of December 31, 2016.
