PSU activity

Our executive officers and other senior employees have been granted PSUs with vesting occurring when performance conditions are met. The number of units earned and eligible to vest are determined based on the achievement of various performance conditions, including gross profit, annual recurring revenue, cumulative paid accounts, subscriptions and services gross margin, and the recipients’ continued services. At the end of each reporting period, we evaluate the probability of achieving the performance conditions and record the related stock-based compensation expense based on the estimated achievement over the service period.
