These initiatives affected all segments, with the exception of Enterprise Networks during the period. The liability for the plan is expected to be paid in 2018.

In the first quarter of 2018, ARRIS recorded restructuring charges of $10.5 million related to severance and employee termination benefits for 850 employees, including the planned sale of the factory in Taiwan. This initiative affected all segments. The liability for the plan is expected to be paid in 2018.

In 2017, ARRIS recorded restructuring charges of $13.3 million related to severance and employee termination benefits for 195 employees. This initiative affected all segments. The liability for the plan has been materially settled as of June 30, 2018.

In first quarter of 2016, ARRIS completed its acquisition of Pace. ARRIS initiated restructuring plans as a result of the combination that focuses on the rationalization of personnel, facilities and systems across the ARRIS organization. The estimated cost recorded during 2016 was approximately $96.3 million. The restructuring plan affected approximately 1,545 employees across the company. The remaining liability is expected to be settled in 2018.

This amount is included in the Consolidated Statement of Operations in the line item titled “Integration, acquisition, restructuring and other costs”.

Contractual obligations – ARRIS has accruals representing contractual obligations that relate to excess leased facilities. A liability for such costs is recognized and measured initially at fair value on the cease-use date based on remaining lease rentals, adjusted for the effects of any prepaid or deferred items recognized, reduced by the estimated sublease rentals that could be reasonably obtained even if it is not the intent to sublease. The fair value of these liabilities is based on a net present value model using a credit-adjusted risk-free rate. The liability will be paid out over the remainder of the leased properties’ terms, which continue through 2021. Actual sublease terms may differ from the estimates originally made by the Company. Any future changes in the estimates or in the actual sublease income could require future adjustments to the liabilities, which would impact net income in the period the adjustment is recorded.

During the year ended December 31, 2017, the Company exited three facilities and recorded a charge of $5.7 million.
