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

The Company’s long-term incentive plans allow for the grant of various types of share-based awards to key employees and directors of the Company and its affiliates. The Company generally awards grants on an annual basis.

In February 2018, the Company granted Restricted Stock Units (“RSUs”), Performance Units (“PUs”) and stock options. The RSUs cliff vest after three years, the PUs cliff vest at the end of their three-year performance period, and the stock options vest ratably over three years. The number of PUs that will vest depends on the Company’s achievement of target performance goals related to the Company’s return on invested capital (“ROIC”), which may range from 0% to 200% of the target award amount. The grant-date fair value of the RSUs and PUs was determined using the closing price of the Company’s common stock on the date of grant. The grant-date fair value of the stock options was determined using the Black-Scholes option pricing model.

During the three months ended March 31, 2018 and 2017, the Company paid $13,279 and $4,296 of cash to settle PUs that vested in February 2018 and February 2017, respectively.
