[1] The fair value of a restricted share, deferred share and fully-vested share is equal to the Company’s closing stock price on the date of grant.

[2] Restricted Stock Units (“RSU”s) were primarily granted in connection with the time-vested portion of the 2017-2018 LTIP. The RSUs vest in two tranches with the first 50% vesting on April 1, 2019 and the remaining vesting 50% on April 1, 2020.

[3] The 100,554 shares of deferred stock, with a fair value of approximately $232,064, represent compensation to certain directors in lieu of cash, in accordance with their irrevocable elections. The shares of deferred stock vest three years from the date of grant or at separation of service, based on the irrevocable election of each director.

[4] During fiscal 2017, the Company granted 86,503 shares of stock, with a fair value of approximately $204,477 to certain directors as compensation in lieu of cash, in accordance with their irrevocable elections. Directors are required to elect 50% of their quarterly retainer in equity. Any shares in excess of the minimum required election are issued from the Third Amended and Restated Non-Employee Director Stock Purchase Plan (the “Non-Employee Director Compensation Plan”).
