Under Plan #2, if bookings were below 90% of target, no options would have been earned, and the 2024 Plan #2 PSOs would have been forfeited in full. If the threshold of 90% of target was achieved, then the options would have been earned at 75%, with an increasing percentage of options earned above threshold up to 100% earned for target performance. As indicated above in Plan #1, we do not disclose our booking goals. The total number of PSOs earned was capped at 100% of target (i.e., no upside). The table below outlines the performance achievement opportunity for the 2024 Plan #2 Performance-Based Stock Options.
