On May 3, 2021, the Board of Directors approved the modifications to the vesting of restricted stock and Liquidity Event option awards held by certain current and former members of management. The modification of restricted stock pertained to an award originally granted to a current member of management, for which the original vesting pattern was on a cliff-vesting basis over a three-year period. Upon modification, the vesting for 50% of the award was accelerated to six months from the date of the Company’s IPO. The result of the modification was an additional $1.4 million of stock-based compensation expense recorded for the fiscal quarter ended July 4, 2021. There was no modification to the vesting conditions for the remaining 50% of the award and no additional shares granted as a result of the modification. The total compensation cost relating to unvested shares not yet recognized for this award as of the quarter ended July 4, 2021 was $1.3 million. The unrecognized expense will be recognized over a period of 1.2 years. The other modification related to an award granted to a former member of management for which the original vesting was contingent on a certain liquidity event as defined by the option agreement. The modification changed the vesting for the award such that the entirety of the award vested on the date the modification was approved by the Board of Directors. The modification resulted in an additional $4.6 million of stock-based compensation expense recorded for the fiscal quarter ended July 4, 2021. The additional expense related to both award modifications is recorded as a component of Selling, marketing and administrative expenses.
