Note 16. Stock-Based Compensation
The Company’s selling, general and administrative expenses for the fiscal years ended March 27, 2022, March 28, 2021, and March 29, 2020 includes $1,338,900, $1,211,000, and $1,174,600, respectively, of stock compensation expense. Provision for income taxes for the fiscal years ended March 27, 2022, March 28, 2021, and March 29, 2020 includes $365,500, $255,600, and $386,100, respectively, of income tax benefits related to our stock-based compensation arrangements. Stock compensation expense is primarily related to our PSUs, RSUs, and Stock Options, granted or outstanding under the Company’s Third Amended and Restated Stock and Incentive Plan (the “1994 Plan”) and 2019 Stock and Incentive Plan (the “2019 Plan” and together with the 1994 Plan, the “Plans”), which was approved at the Annual Meeting of Shareholders held on July 25, 2019. No additional awards may be granted under the 1994 Plan, although awards outstanding under the 1994 Plan remain outstanding and governed by its terms. As of March 27, 2022, 344,371 shares were available for issue in respect of future awards under the 2019 Plan.
Performance Stock Units: Under a program established by the Board of Directors, PSUs have been granted under the Plans to selected employees. Each PSU entitles the participant to earn Tessco common stock, but only after certain performance measures are reached and individual performance targets are met over a defined performance cycle. Performance cycles, which are fixed for each grant at the date of grant, are one year. Once earned, shares vest and are issued over a specified period of time determined at the time of the grant, provided that the participant remains employed by or associated with the Company at the time of share issuance. Performance targets are set by the Board of Directors in advance for the complete performance cycle at levels designed to grow shareholder value. If actual performance does not reach the minimum annual or threshold targets, no shares are issued. In accordance with ASC 718, the Company records compensation expense on its PSUs over the service period, based on the number of shares management estimates will ultimately be issued. Accordingly, the Company determines the periodic financial statement compensation expense based upon the stock price at the PSU grant date, net of the present value of dividends expected to be paid on Tessco common stock before the PSU vests, management’s projections of performance over the performance period, and the resulting amount of estimated share issuances. As discussed in Note 2 above, the Company accounts for forfeitures as they occur rather than estimate expected forfeitures. To the extent that forfeitures occur, stock-based compensation related to the restricted awards may be different from the Company’s expectations.
