Prior to the Business Combination, share-based payments to employees include grants of restricted share units (“RSUs”) and performance based restricted share units (“PRSUs”), which consist of both Class A-1 and Class B common units in each type, are measured based on their estimated grant date fair value. The Company recognizes compensation expense on a straight-line basis over the requisite service period for awards expected to ultimately vest. As a result of the change in control related to the Business Combination, the vesting of the time-based RSU Class B units accelerated on the Closing Date. The remaining unvested PRSU Class B units have vesting conditions that are contingent upon the achievement of defined internal rates of return and multiples on invested capital occurrence and of certain liquidity events. The Class A-1 RSUs and PRSUs that were unvested as of the Closing Date have time-based and/or vesting conditions that are contingent upon the achievement of defined internal rates of return and multiples on

invested capital occurrence and of certain liquidity events. Both the unvested Class A-1 and Class B units were replaced with unvested Alight common shares as discussed below.

The following tables summarizes the unit activity related to the RSUs and PRSUs during the Predecessor periods as follows:

In connection with the Business Combination, the holders of certain unvested awards under the Predecessor plans were granted replacement awards in the Successor company.

The Class B and Class A-1 units that were replaced represent the Unvested Class A, Unvested Class B-1 and Unvested Class B-2 common shares subject to the forfeiture re-allocation provision per the Class Z instruments discussed in Note 9 “Stockholders’ and Members’ Equity”. These unvested shares are accounted for as restricted stock in accordance with ASC 718.

In connection with the Business Combination, the Company adopted the Alight, Inc. 2021 Omnibus Incentive Plan. Under this plan, for grants issued during the Successor six months ended December 31, 2021, approximately 50% of the units are subject to time-based vesting requirements and approximately 50% are subject to performance-based vesting requirements. The majority of the time-based RSUs vest ratably each December 31 over a three-year period with one-third vesting on December 31, 2021, 2022 and 2023. The majority of the PRSUs vest upon achievement of the Company’s performance goal, Total Contract Value of Business Process as a Service ("BPaaS"). The Company recognizes expense associated with the PRSUs when the achievement of the performance condition is deemed probable.

The aggregate grant date fair value of RSUs and PRSUs granted during the Successor period six months ended December 31, 2021 was $119 million and $115 million, respectively.
