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 grant date fair value of the RSUs is equal to the value of the shares acquired by the Predecessor’s initial investors at the time of Alight Holding’s formation in 2017. The grant date fair values of the PRSUs are based on a Monte Carlo simulation methodology, which requires management to make certain assumptions and apply judgement.

Management determined the expected volatility based on the average implied asset volatilities of comparable companies as we do not have sufficient trading history for the PRSUs. The expected term represents the period that the PRSUs are expected to be outstanding. Because of the lack of sufficient historical data necessary to calculate the expected term, we used the contractual vesting period of five years to estimate the expected term. For the Predecessor period, the key assumptions included in the Monte Carlo simulation were expected volatility of 45%, a risk-free interest rate of 1% and no expected dividends.

The Company recognizes share-based 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 PRSU Class B units accelerated on the Closing Date. Prior to the Closing Date, the time-based PRSUs vested ratably over periods of one to five years. 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 shares of Alight common stock as discussed below.

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

Share-based payments consist of grants of RSUs and PRSUs. The Company recognizes compensation expense on a straight-line basis over the requisite service period for awards expected to ultimately vest.

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 Stock 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 year ended December 31, 2023, approximately 60% of the units are subject to time-based vesting requirements and approximately 40% are subject to performance-based vesting requirements. The majority of the time-based RSUs vest ratably on an annual basis over a three-year period. The PRSUs granted vest upon achievement of various performance metrics aligned to goals established by the Company. As of December 31, 2023, there were 86,428,864 remaining shares of common stock authorized for issuance pursuant to the Company’s stock-based compensation plans under its 2021 Omnibus Incentive Plan.

The Company begins to recognize expense associated with the PRSUs when the achievement of the performance condition is deemed probable. During the year ended December 31, 2023, expected achievement levels did not change for any of the performance periods based on management's analysis of the corresponding performance conditions.

The fair value of each RSU and PRSU is based upon the grant date market price. The aggregate grant date fair value of RSUs and PRSUs granted during the Successor year ended December 31, 2023 was $58 million and $48 million, respectively.

The following tables summarizes the unit activity related to the RSUs and PRSUs during the Successor years ended December 31, 2023, December 31, 2022 and the Successor six months ended December 31, 2021:

These share totals include both unvested shares and restricted stock units.

(2)

PRSUs granted includes both new grants in the period as well as adjustments in the period to existing grants to account for the expected level of achievement of the performance-based vesting requirements.

Total share-based compensation costs related to the RSUs and PRSUs are recorded in the Consolidated Statement of Comprehensive Income (Loss) as follows (in millions):


	Successor						Predecessor
	Year Ended		Year Ended		Six Months Ended		Six Months Ended
	December 31,		December 31,		December 31,		June 30,
	2023		2022		2021		2021
Cost of services, exclusive of depreciation and amortization	$	39	$	40	$	19	$	1
Selling, general and administrative		121		141		48		4
Total share-based compensation expense	$	160	$	181	$	67	$	5

As of December 31, 2023, total future compensation expense related to unvested RSUs is $50 million which will be recognized over a remaining weighted-average amortization period of approximately 1.5 years. As of December 31, 2023, total future compensation expense related to PRSUs is $57 million which will be recognized over the next 1.5 years.

In December 2022, the Company began offering its employees an Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, all full-time and certain part-time employees of the Company based in the U.S. and certain other countries are eligible to purchase Class A Common Stock of the Company twice per year at the end of a six-month payment period (a “Payment Period”). During each Payment Period, eligible employees who so elect may authorize payroll deductions in an amount no less than 1% nor greater than 10% of his or her base pay for each payroll period in the Payment Period. At the end of each Payment Period, the accumulated deductions are used to purchase shares of Class A Common Stock from the Company up to a maximum of 1,250 shares for any one employee during a Payment Period. Shares are purchased at a price equal to 85% of the fair market value of the Company’s Class A Common Stock on the last business day of a Payment Period. As of December 31, 2023, there were 11,961,530 remaining shares available for grant under the ESPP. For the year ended as of December 31, 2023, 1,499,751 shares had been issued under the ESPP and the amount of share-based compensation expense related to the ESPP was $2 million.
