Subsequent Events On April 6, 2022, the Company entered into a 2022 Executive Performance RSU Award Agreement (the “2022 Agreement”) with certain officers, including its President and Chief Executive Officer pursuant to which each 2022 Participating Executive will have the opportunity to earn a specified amount of RSUs. The amount of RSUs awarded, if any, will be based on the Company’s achievement of varying levels of operating income before the impact of incentive pay (but including adjustments to reflect the payment of sales commissions) in fiscal 2022 (“Operating Income”), as determined by the Company, in its sole discretion. Nevertheless, no Participating Executive will be entitled to any such RSUs unless the Company achieves a minimum of $1 million in Operating Income in 2022. If awarded, such RSUs will vest in equal amounts (i.e., 1/3, 1/3 and 1/3) over three years commencing one year after the grant date based on continued service. Such RSUs are valued at the date of grant based on the closing price of the Company’s common stock on the grant date. Currently there is no expense reflected in the financial statements for these awards as the achievement is not considered probable.
