Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

The Company has a 2017 Stock Incentive Plan ("the 2017 SIP") that provides for granting of stock options, restricted stock units and other equity awards. The 2017 SIP authorizes 3,636,000 shares of common stock for issuance. The 2017 SIP is designed to motivate and retain individuals who are responsible for the attainment of the Company's primary long-term performance goals.

The Company utilizes the Black-Scholes option-pricing model to estimate the grant-date fair value of all stock options granted during the years ended December 31, 2018 and 2017. The Black-Scholes option-pricing model requires the use of weighted average assumptions for estimated expected volatility, estimated expected term of stock options, risk-free rate, estimated expected dividend yield, and the fair value of the underlying common stock at the date of grant. Due to the recent date of the IPO, the Company does not have sufficient history to estimate the expected volatility of its common stock price. Thus, expected volatility has been based on the average volatility of peer public entities that are similar in size and industry. The Company estimates the expected term of all stock options based on the simplified method. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the stock option. The expected dividend yield is 0.0% as the Company has not declared any common stock dividends to date and does not expect to declare common stock dividends in the near future. The fair value of the underlying common stock at the date of grant was determined based on the value of the common stock at the date of grant. Forfeitures are recorded when incurred. The weighted average assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2018 and 2017, are set forth below:



	Year Ended December 31, 2018			Year Ended December 31, 2017
Expected term (in years)	6.25			6.25
Expected volatility	44.8		%	49.8		%
Risk-free interest rate	2.8		%	2.1		%
Expected dividend	—			—
Weighted average fair value at grant date	$	7.30		$	7.02

During the years ended December 31, 2018 and 2017, the Company granted 340,558 and 225,745 stock options, respectively, to employees that vest based on service only. All of these awards vest over a four-year period. The Company did not issue any stock options prior to its IPO in February 2017.

Long-Term Incentive Plan

Following the Lone Star Acquisition, Lone Star implemented the LSF9 Cypress Parent LLC Long-Term Incentive Plan (the "LTIP"). Under the LTIP, participants were granted pool units entitling them, subject to the terms of the LTIP, to a potential cash payout upon a monetization event. The LTIP was effective October 9, 2015. The LTIP was assigned from Parent to the Company in connection with the IPO.

The LTIP was established with the purpose of attracting certain key employees and other service providers of the Company and its subsidiaries and to provide motivation to put forth maximum efforts toward the continued growth, profitability and success of the Company by providing incentives.

The Board of the Company administers the LTIP and awards pool units. Pool units vest 10% each year for the first three years. Pool units, whether vested or unvested, that are outstanding on the 5th anniversary of the date the award was granted will be forfeited on that date or, upon the date the participant ceases employment. Pool units will remain outstanding for a period of six months from the date of such termination if the termination is without cause, a resignation for good reason, due to death or due to disability. Total pool units available for grant under the LTIP is 1,000,000. At December 31, 2018 and December 31, 2017, there were 867,000 and 925,000 pool units outstanding, respectively.

The Company maintains an incentive pool account and upon a monetization event and obtaining a cumulative internal rate of return of at least 15%, the Company will credit to the incentive pool account amounts as defined in the LTIP and determined by the cumulative internal rate of return achieved at the time of the monetization event. A monetization event, as defined by the LTIP, is one of the following transactions: (a) the Company is sold, transferred or otherwise disposed of to an unrelated third party for cash; (b) a firm commitment underwritten public offering of the equity interests of the Company; or (c) the payment by the Company of any cash distributions to investors. Following a monetization event, the value of any incentive amount to be paid to a participant will be determined by the percentage of a participant’s pool units awarded to the total pool units awarded under the LTIP times the amount in the incentive pool account. Participants will be paid within 60 days following the monetization event.

At December 31, 2018, there had not been a monetization event and, therefore, no amounts were accrued in the accompanying consolidated balance sheets and no expense has been recognized for the LTIP. On February 15, 2017, the Company completed the IPO; however, the IPO was not a monetization event and no payout was triggered under the LTIP.
