Share-based Payment Arrangement [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 2019, 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”) and total shareholder return, which may range from 0% to 200% of the target award amount.
