(1) From time to time, the Company makes advance payment to a supplier for future inventory in order to secure more favorable pricing. The Company anticipates that this amount will be offset in the first quarter of 2017 against the accounts payable owed to this supplier.

(2) The Company’s acquired TVN subsidiary in France (the “TVN French Subsidiary”) participates in the French Crédit d’Impôt Recherche (“CIR”) program (the “R&D tax credits”) which allows companies to monetize eligible research expenses. The French R&D tax credits can be used to offset against income tax payable to the French government in each of the four years after being incurred, or if not utilized, are recoverable in cash. TVN French Subsidiary has accumulated approximately $27.6 million of French R&D tax credit receivables at April 1, 2016 for claims from 2012 through 2016. These amounts are subject to audit by the French government and as of April 1, 2016, the 2012 audit for these French R&D credits has been completed and $5.8 million of the French R&D tax credit receivables is expected to be recoverable in 2016. The remaining $21.8 million is expected to be recoverable in 2017 and 2018 and this amount is reported under “Other Long-term Assets” on the Company’s Condensed Consolidated Balance Sheets. Pursuant to the TVN Purchase Agreement, the Company is indemnified by the selling shareholders with respect to the validity and recoverability of the outstanding TVN French Subsidiary R&D tax credit receivables.

(3) The restricted cash balances are primarily held as cash collateral security for certain bank guarantees. These restricted funds are invested in bank deposits and cannot be withdrawn from the Company’s accounts without the prior written consent of the applicable secured party. Additionally, as of April 1, 2016, the Company recorded approximately $1.1 million of restricted cash for the bank guarantee associated with the TVN French Subsidiary’s office building lease. This amount is reported under “Other Long-term Assets” on the Company’s Condensed Consolidated Balance Sheets.
