(1)

The Company adopted ASC 606 on January 1, 2018 using the modified retrospective method for all revenue-generating contracts, including modifications thereto, that were not completed contracts at the date of adoption. As a result of adopting ASC 606, the Company recorded a net decrease of $3.1 million to its accumulated deficit at January 1, 2018, representing the cumulative impact of adopting ASC 606.

Share-Based Compensation

The Company recognized share-based compensation expense of $24.7 million and $17.9 million during the three months ended March 31, 2019 and 2018, respectively. As of March 31, 2019, the total remaining unrecognized compensation cost related to non-vested share-based compensation awards amounted to $88.4 million.

There are 0.2 million performance share units outstanding as of March 31, 2019, representing target amounts, for which a grant date has not been established. No fair value has been ascribed to these awards as no grant date has been established. Accordingly, they are not reflected in the remaining unrecognized compensation cost above or the weighted average remaining requisite service period below.

As of March 31, 2019, the weighted average remaining requisite service period for non-vested stock options was 1.5 years and for non-vested restricted stock units was 2.2 years.
