Long-term incentive compensation awards may be granted to certain eligible employees or non-employee directors. A detailed description of the awards granted prior to 2021 is included in our 2020 Annual Report on Form 10-K.

Awards granted on March 1, 2021 to executive officers and other members of senior management were comprised of performance stock units (“PSU’s”), stock options, and time-based restricted stock units (“RSU’s”), while other eligible employees were granted PSU’s and RSU’s. The PSU’s are eligible to vest at the end of a three-year performance period, with performance based on the total return of our stock over the three-year performance period against a peer group within the S&P 600 Capital Goods Index. Stock options and RSU’s vest ratably over the three-year period subsequent to the date of grant.

Effective May 11, 2021, we granted 0.017 RSU's to our non-employee directors, which vest in their entirety immediately prior to the annual meeting of stockholders in May 2022.
