Stock‑based compensation expense is measured at the grant date fair value of the award and is recognized ratably over the requisite service period, which is generally the vesting period. Specifically for performance‑based RSUs, stock‑based compensation expense is measured at the grant date fair value of the award and is recognized ratably over the requisite service period based on the number of awards expected to vest at each reporting date. The Company accounts for forfeitures of equity awards as those forfeitures occur.

Restricted Stock and RSUs

Under the equity incentive plans, the Company may grant both time‑based and performance‑based shares of restricted Class B Common Stock and RSUs to eligible colleagues. Time‑based awards generally vest ratably on each of the first four anniversaries of the grant date. Performance‑based awards vesting is determined by the achievement of certain business profitability and growth targets, including growth in annualized recurring revenues (“ARR”), and actual bookings for perpetual licenses and non‑recurring services, among others. Performance targets are generally set for performance periods of one to three years.

(1)For the six months ended June 30, 2023, the Company only granted RSUs.

(2)Includes 64,939 RSUs which are expected to be settled in cash.

(3)Includes 199,076 time‑based RSUs granted during the three months ended March 31, 2022 to certain officers and key employees, which cliff vest on January 31, 2025.

(4)Primarily relates to the 2022 annual performance period, except for 185,186 performance‑based RSUs granted during the year ended December 31, 2022 with extraordinary terms, which are described below.

(5)Primarily relates to the 2023 annual performance period, except for 13,367 additional shares earned based on the achievement of 2022 performance goals for performance‑based RSUs granted during the year ended December 31, 2022.

During the year ended December 31, 2022, the Company granted 185,186 performance‑based RSUs to certain officers and key employees, which vest subject to the achievement of certain performance goals over a three‑year performance period (the “Performance Period”). For each year of the Performance Period, one‑third of the performance‑based RSUs will be subject to a cliff, whereby no vesting of that portion will occur unless the Company’s applicable margin metrics (which, for 2022, was Adjusted EBITDA margin and for 2023 and 2024, will be Adjusted operating income inclusive of stock-based compensation expense (“Adjusted OI w/SBC”) margin, excluding the impact of currency exchange fluctuations) also equals or exceeds the relevant target level for such year. Provided that the applicable margin targets are met, the total number of performance‑based RSUs that will vest is determined by the achievement of growth targets, which include growth in ARR, as well as actual bookings for perpetual licenses and non‑recurring services. Final actual vesting will be determined on January 31, 2025. The 2022 Adjusted EBITDA margin target for the performance‑based RSUs was met.

In 2016, the Company granted RSUs subject to performance‑based vesting as determined by the achievement of certain business growth targets. Certain colleagues elected to defer delivery of such shares upon vesting. During the six months ended June 30, 2023 and 2022, 1,562 and 10,888 shares, respectively, were delivered to colleagues, and 20 and 16 additional shares, respectively, were earned as a result of dividends. As of June 30, 2023 and December 31, 2022, 7,821 and 9,363 shares, respectively, of these vested and deferred RSUs remained outstanding.

The weighted average grant date fair values of RSUs granted were $40.80 and $39.02, for the six months ended June 30, 2023 and 2022, respectively.

For the six months ended June 30, 2023 and 2022, restricted stock and RSUs were issued net of 104,773 and 52,026 shares, respectively, which were sold back to the Company to settle applicable income tax withholdings of $4,336 and $2,148, respectively.

As of June 30, 2023, there was $8,437 of unrecognized compensation expense related to unvested performance‑based RSUs, which is expected to be recognized over a weighted average period of approximately 1.0 years.
