Warrants	Note 17. Warrants During 2016, the Company entered into two separate Warrant and Registration Rights Agreements (the “Warrants”) with certain customers pursuant to which those customers may purchase up to 14.0 million of ARRIS’s ordinary shares, (subject to adjustment in accordance with the terms of the Warrants, the “Shares”). The Warrants will vest in tranches based on the amount of purchases of products and services by the customer from the Company. At December 31, 2017, approximately 2.2 million Warrants were vested and outstanding, with a weighted average exercise price of $24.56, which vested based on the amount of purchases of products and services by the customers from the Company in 2016. The ordinary shares issuable under our outstanding Warrant program with a customer, based on achieving certain purchase levels in 2018, are between 1.0 million and 2.5 million at an exercise price for the warrants of $26.14. For Warrants, other than those issuable in 2018, the exercise price per Share was established based upon the average volume-weighted price of ARRIS’s ordinary shares on NASDAQ for the 10-day trading period preceding the date of the Warrants. For Warrants issuable in 2018, the exercise price was set based on the volume-weighted price for the 10-day trading period preceding January 1, 2018. The Warrants provide for net Share settlement that, if elected by the holders, will reduce the number of Shares issued upon exercise to reflect net settlement of the exercise price. Customers’ may also request cash settlement of the Warrants upon exercise in lieu of issuing Shares, however, such cash election is at the discretion of ARRIS. The Warrants will expire by September 30, 2023. The Warrants provide for certain adjustments that may be made to the exercise price and the number of Shares issuable upon exercise due to customary anti-dilution provisions based on future corporate events. In addition, in connection with any consolidation, merger or similar extraordinary event involving the Company, the Warrants will be deemed to represent the right to receive, upon exercise, the same consideration received by the holders of the Company’s ordinary shares in connection with such transaction. Upon a change of control of ARRIS or if ARRIS materially breaches its applicable agreements with customers (and such breach is not cured pursuant to the terms of the agreements), the Warrants will immediately vest for the minimum threshold of Shares that would otherwise be issuable. ARRIS has also agreed, if requested by the holders, to register the Shares issuable upon exercise of the Warrants under the Securities Act of 1933, as amended (the “Securities Act”) and has also granted “piggyback” registration rights in the event ARRIS files a registration statement with the U.S. Securities and Exchange Commission under the Securities Act covering its equity securities, subject to the terms and conditions included in the Warrants. Because the Warrants contain performance criteria, which includes aggregate purchase levels and product mix, under which customers must achieve for the Warrants to vest, as detailed above, the final measurement date for the Warrants is the date on which the Warrants vest. Prior to the final measurement, when achievement of the performance criteria has been deemed probable, the estimated fair value of Warrants is being recorded as a reduction to net sales based on the projected number of Warrants expected to vest, the proportion of purchases by customers and its affiliates within the period relative to the aggregate purchase levels required for the Warrants to vest and the then-current fair value of the related Warrants. To the extent that projections change in the future as to the number of Warrants that will vest, as well as changes in the fair market value of the Warrants, a cumulative catch-up adjustment will be recorded in the period in which the estimates change. The fair value of the Warrants is determined using the Black-Scholes option pricing model. The assumptions utilized in the Black-Scholes model include the risk-free interest rate, expected volatility, and expected life in years. The risk-free interest rate over the expected life is equal to the prevailing U.S. Treasury note rate over the same period. Expected volatility is determined utilizing historical volatility over a period of time equal to the expected life of the warrant. Expected life is equal to the remaining contractual term of the warrant. The dividend yield is assumed to be zero since we have not historically declared dividends and do not have any plans to declare dividends in the future. For the year ended December 31, 2017 and 2016, ARRIS recorded zero and $30.2 million, respectively, as a reduction to net sales in connection with Warrants. This transaction is considered an equity contract, and is classified as such.

Note 17. Warrants

During 2016, the Company entered into two separate Warrant and Registration Rights Agreements (the “Warrants”) with certain customers pursuant to which those customers may purchase up to 14.0 million of ARRIS’s ordinary shares, (subject to adjustment in accordance with the terms of the Warrants, the “Shares”).

The Warrants will vest in tranches based on the amount of purchases of products and services by the customer from the Company. At December 31, 2017, approximately 2.2 million Warrants were vested and outstanding, with a weighted average exercise price of $24.56, which vested based on the amount of purchases of products and services by the customers from the Company in 2016.

The ordinary shares issuable under our outstanding Warrant program with a customer, based on achieving certain purchase levels in 2018, are between 1.0 million and 2.5 million at an exercise price for the warrants of $26.14.

For Warrants, other than those issuable in 2018, the exercise price per Share was established based upon the average volume-weighted price of ARRIS’s ordinary shares on NASDAQ for the 10-day trading period preceding the date of the Warrants.

For Warrants issuable in 2018, the exercise price was set based on the volume-weighted price for the 10-day trading period preceding January 1, 2018.

The Warrants provide for net Share settlement that, if elected by the holders, will reduce the number of Shares issued upon exercise to reflect net settlement of the exercise price. Customers’ may also request cash settlement of the Warrants upon exercise in lieu of issuing Shares, however, such cash election is at the discretion of ARRIS. The Warrants will expire by September 30, 2023.

The Warrants provide for certain adjustments that may be made to the exercise price and the number of Shares issuable upon exercise due to customary anti-dilution provisions based on future corporate events. In addition, in connection with any consolidation, merger or similar extraordinary event involving the Company, the Warrants will be deemed to represent the right to receive, upon exercise, the same consideration received by the holders of the Company’s ordinary shares in connection with such transaction. Upon a change of control of ARRIS or if ARRIS materially breaches its applicable agreements with customers (and such breach is not cured pursuant to the terms of the agreements), the Warrants will immediately vest for the minimum threshold of Shares that would otherwise be issuable.

ARRIS has also agreed, if requested by the holders, to register the Shares issuable upon exercise of the Warrants under the Securities Act of 1933, as amended (the “Securities Act”) and has also granted “piggyback” registration rights in the event ARRIS files a registration statement with the U.S. Securities and Exchange Commission under the Securities Act covering its equity securities, subject to the terms and conditions included in the Warrants.

Because the Warrants contain performance criteria, which includes aggregate purchase levels and product mix, under which customers must achieve for the Warrants to vest, as detailed above, the final measurement date for the Warrants is the date on which the Warrants vest. Prior to the final measurement, when achievement of the performance criteria has been deemed probable, the estimated fair value of Warrants is being recorded as a reduction to net sales based on the projected number of Warrants expected to vest, the proportion of purchases by customers and its affiliates within the period relative to the aggregate purchase levels required for the Warrants to vest and the then-current fair value of the related Warrants. To the extent that projections change in the future as to the number of Warrants that will vest, as well as changes in the fair market value of the Warrants, a cumulative catch-up adjustment will be recorded in the period in which the estimates change.

The fair value of the Warrants is determined using the Black-Scholes option pricing model. The assumptions utilized in the Black-Scholes model include the risk-free interest rate, expected volatility, and expected life in years. The risk-free interest rate over the expected life is equal to the prevailing U.S. Treasury note rate over the same period. Expected volatility is determined utilizing historical volatility over a period of time equal to the expected life of the warrant. Expected life is equal to the remaining contractual term of the warrant. The dividend yield is assumed to be zero since we have not historically declared dividends and do not have any plans to declare dividends in the future.

For the year ended December 31, 2017 and 2016, ARRIS recorded zero and $30.2 million, respectively, as a reduction to net sales in connection with Warrants. This transaction is considered an equity contract, and is classified as such.
