Incentive Compensation Plans Long Term Incentive Plan Awards In connection with the Omnibus Incentive Plan, during the nine months ended December 31, 2020, we granted to our employees and directors one or a combination of time-vesting restricted stock units, cash settled restricted stock units, and performance stock units under vesting terms that generally vary from one to four years from the date of grant.
