(1) 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 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. The amount of R&D tax credits recoverable are subject to audit by the French government. The R&D tax credit receivables at June 30, 2017 were approximately $24.3 million and are expected to be recoverable from 2018 through 2021 with $6.3 million reported under “Prepaid and other Current Assets” and $18.0 million reported under “Other Long-term Assets” on the Company’s Condensed Consolidated Balance Sheets.

(2) On September 26, 2016, the Company issued a warrant to purchase shares of its common stock (the “Warrant”) to Comcast pursuant to which Comcast may, subject to certain vesting provisions, purchase up to 7,816,162 shares of the Company’s common stock subject to adjustment in accordance with the terms of the Warrant, for a per share exercise price of $4.76. The portion of the Warrant which vested on September 26, 2016 had a value of approximately $1.6 million and is deemed a customer incentive paid upfront and cumulatively, $0.9 million of this prepaid incentive has been recorded as a reduction to the Company’s net revenues from Comcast. The remaining $0.7 million of this prepaid incentive is reported as an asset under “Prepaid expenses and other current assets” on the Company’s Condensed Consolidated Balance Sheet as of June 30, 2017. The Company considers this asset to be recoverable based on the expectation of Comcast’s future purchases of the pertinent products.

(3) The restricted cash balances are 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 These restricted funds are invested in bank deposits and cannot be withdrawn from the Company’s accounts without the prior written consent of the applicable secured party.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 June 30, 2017, 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.
