Share-based payment award, Terms						RSAs granted under the 2014 Plan are subject to a service-based vesting condition and generally vest in equal monthly installments over four years. RSUs granted under the 2014 Plan are subject to two vesting conditions: (i) a service-based vesting condition that is generally met over four years with 25% of the shares vesting on the first anniversary of the grant date with monthly vesting thereafter, and (ii) a performance-based vesting condition that is met through a liquidity event in the form of either a change of control or an initial public offering (“the performance condition”). RSUs granted under the 2021 Plan are subject to a service-based vesting condition only that is generally met over four years with 25% of the shares vesting on the first anniversary of the grant date with monthly vesting thereafter.

Share-based payment award, Plan modification terms						As a result of the Business Combination, on November 17, 2021 the Board of Directors modified the vesting terms of RSUs granted under the 2014 Plan to allow 10% of the RSUs that met the service condition as of the closing of the Business Combination (the “10% RSUs”) to vest with respect to the performance condition, effective as of November 19, 2021, the date on which the Form S-8 registration statement covering such shares became effective. In addition, on November 17, 2021 the Board of Directors modified the vesting terms of the remaining RSUs granted under the 2014 Plan such that they will vest in full with respect to the performance condition on or before March 15, 2022 (the original service-based vesting condition is still applicable). As a result of these modifications, the performance condition for all RSUs granted under the 2014 Plan became probable of being met during the fourth quarter of 2021.

Share-based payment award vesting rights, Description						RSUs granted to non-employee directors by adding a cash settlement feature to the awards which allowed the non-employee directors to elect to settle in cash up to 50% of their RSUs that were vested with respect to the service condition on or prior to December 31, 2021 (the “50% RSUs”). The director RSUs were subject to the same performance condition as all other RSUs granted under the 2014 Plan. In the fourth quarter of 2021, all directors elected to cash settle the 50% RSUs. As a result, the 50% RSUs are classified as liability awards and the liability is measured at fair value at the reporting date.
