CII Common and Preferred Units

Prior to the Company’s IPO, the Company was given authorization by Communications Infrastructure Investments, LLC (“CII”) to award 625,000,000 of CII’s common units as profits interests to employees, directors, and affiliates of the Company. The common units were historically considered to be stock-based compensation with terms that required the awards to be classified as liabilities due to cash settlement features. The vested portion of the awards was reported as a liability and the fair value was re-measured at each reporting date until the date of settlement, with a corresponding charge (or credit) to stock-based compensation expense. On December 31, 2016, the CII common units became fully vested and as such there is no remaining unrecognized compensation cost associated with CII common units for any period subsequent to December 31, 2016.

The value of the CII common units was derived from the value of CII’s investments in the Company and Onvoy, LLC and its subsidiaries (“OVS”), a company that provided voice and managed services which the Company spun off during the year ended June 30, 2014. As the value derived from each of these investments was separately determinable and there was a plan in place to distribute the value associated with the investment in Company shares separate from the value derived from OVS, the two components were accounted for separately. The OVS component of the CII awards was adjusted to fair value each reporting period. On December 31, 2015, CII entered into an agreement to sell OVS to a third party. The sale was completed in May 2016. Based on the sale price, the estimated fair value of OVS awards was increased, resulting in an increase to stock based compensation expense and corresponding increase to additional paid-in capital of $12.9 million for the year ended June 30, 2016. Proceeds from the sale to be distributed to the Company’s employees was paid by CII.

During the years ended June 30, 2018, 2017 and 2016, the Company recognized nil, $10.1 million and $73.0 million, respectively, of stock-based compensation expense related to vesting of CII common and preferred units.

Performance Compensation Incentive Program

During October 2014, the Company adopted the 2014 Performance Compensation Incentive Program (“PCIP”). The PCIP includes incentive cash compensation and equity (in the form of RSUs). Grants under the PCIP RSU plans are made quarterly for all participants. The PCIP was effective on October 16, 2014 and will remain in effect for a period of 10 years (or through October 16, 2024) unless it is earlier terminated by the Company’s Board of Directors.

The PCIP has the following components:

Part A

Under Part A of the PCIP, certain full-time employees, including the Company’s executives, are eligible to earn quarterly awards of RSUs. Each participant in Part A of the PCIP will have an RSU annual award target value, which will be allocated to each fiscal quarter. The final Part A value awarded to a participant for any fiscal quarter is determined by the Compensation Committee of the Board of Directors subsequent to the end of the respective performance period taking into account the Company’s measured value creation for the quarter, as well as such other subjective factors that it deems relevant (including group and individual level performance factors). The number of Part A RSUs granted will be calculated based on the final award value determined by the Compensation Committee divided by the average closing price of the Company’s common stock over the last ten trading days of the respective performance period. Part A RSUs will vest assuming continuous employment fifteen months subsequent to the end of the performance period (for awards relating to periods through June 30, 2017) or twelve months subsequent to the end of the performance period (for awards relating to periods subsequent to June 30, 2017). Upon vesting, the RSUs convert to an equal number of shares of the Company’s common stock. Additionally, under Part A of the PCIP, awards may be granted to certain employees upon commencement of their employment with the Company.

During the years ended June 30, 2018, 2017 and 2016, the Company recognized $82.3 million, $76.5 million and $45.3 million, respectively, of compensation expense associated with Part A awards. The June 2018 and June 2017 quarterly awards were recorded as liabilities totaling $5.7 million and $5.5 million as of June 30, 2018 and 2017, respectively, as the awards represent an obligation denominated in a fixed dollar amount to be settled in a variable number of shares during the subsequent quarter. The quarterly stock-based compensation liability is included in “Accrued liabilities” in the accompanying consolidated balance sheets. Upon the issuance of the RSUs, the liability is re-measured and then reclassified to additional paid-in capital, with a corresponding charge (or credit) to stock based compensation expense. The value of the remaining unvested RSUs is expensed ratably through the vesting date. At June 30, 2018, the remaining unrecognized compensation cost to be expensed over the remaining vesting period for Part A awards is $32.6 million.

The following table summarizes the Company’s Part A RSU activity for the years ended June 2018, 2017 and 2016:


	Number of Part A RSUs	Weighted average grant-date fair value per share		Weighted average remaining contractual term in months
Outstanding at July 1, 2015	933,217	$	26.25	7.1
Granted	2,190,785		26.04

Part B

Under Part B of the PCIP, participants, including the Company’s executives, are awarded quarterly grants of RSUs. The number of the RSUs earned by the participants is based on the Company’s stock price performance over a performance period of one year with the starting price being the average closing price over the last ten trading days of the quarter immediately prior to the date of grant and the vesting date. The RSUs vest assuming continuous employment through the end of the measurement period, twelve months after the beginning of the performance period (for awards vesting on or prior to June 30, 2018) or fifteen months after the beginning of the performance period (for awards vesting after June 30, 2018). The existence of a vesting provision that is associated with the performance of the Company’s stock price is a market condition, which affects the determination of the grant date fair value. Upon vesting, RSUs earned convert to an equal number of shares of the Company’s common stock.

The following table summarizes the Company’s Part B RSU activity for the years ended June 2018, 2017 and 2016:


	Number of Part B RSUs	Weighted average grant-date fair value per unit		Weighted average remaining contractual term in months
Outstanding at July 1, 2015	1,249,873	$	42.90	5.5

Grant date fair value per Part B RSU	$	26.52	$	27.39	$	75.56	$	47.00
Units converted to Company's common stock at vesting date		54,671		41,368		102,511		99,508

During the years ended June 30, 2018, 2017 and 2016, the Company recognized stock-based compensation expense of $12.4 million, $26.0 million and $36.5 million related to Part B awards, respectively.

The grant date fair value of Part B RSU grants is estimated utilizing a Monte Carlo simulation. This simulation estimates the ten-day average closing stock price ending on the vesting date, the stock price performance over the performance period, and the number of common shares to be issued at the vesting date. Various assumptions are utilized in the valuation method, including the target stock price performance ranges and respective share payout percentages, the Company’s historical stock price performance and volatility, peer companies’ historical volatility and an appropriate risk-free rate. The aggregate future value of the grant under each simulation is calculated using the estimated per share value of the common stock at the end of the vesting period multiplied by the number of common shares projected to be granted at the vesting date. The present value of the aggregate grant is then calculated under each of the simulations, resulting in a distribution of potential present values. The fair value of the grant is then calculated based on the average of the potential present values. The remaining unrecognized compensation cost associated with Part B RSU grants is $6.8 million at June 30, 2018.

Part C

Under Part C of the PCIP, independent directors of the Company are eligible to receive quarterly awards of RSUs. Independent directors electing to receive a portion of their annual director fees in the form of RSUs are granted a set dollar amount of Part C RSUs each quarter. The quantity of Part C RSUs granted is based on the average closing price of the Company’s common stock over the last ten trading days of the quarter ended immediately prior to the grant date and vest at the end of each quarter for which the grant was made. During the years ended June 30, 2018, 2017 and 2016, the Company’s independent directors were granted 58,421, 47,420 and 41,793 Part C RSUs, respectively. During the years ended June 30, 2018, 2017 and 2016, the Company recognized $2.0 million, $1.5 million and $1.1 million of compensation expense associated with the Part C RSUs, respectively.
