[1] During the first six months of fiscal 2020, the vesting of RSUs was primarily related to the time-based awards under the Company’s LTIP plans, see Note 5, Long-Term Incentive Plans.

[2] The 45,714 shares of deferred stock, with a grant date fair value of $49,371, represent compensation to certain directors in lieu of cash, in accordance with their irrevocable elections.  The shares of deferred stock will vest three years from the date of grant or at separation of service, based on the irrevocable election of each director pursuant to the Company’s Fourth Amended and Restated Non-Employee Director Compensation Plan (“Non-Employee Director Compensation Plan”)

[3] During the first six months of fiscal 2020, the Company granted 69,440 shares of stock, with a fair value of approximately $74,995, 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 Non-Employee Director Compensation Plan.

[4] The 720,000 shares of performance stock units (“PSUs”), with a fair value of $1.0 million, represent a sign-on grant to Mr. Kanter.  The PSUs vest in installments when the following milestones are met: one-third of the PSUs vest when the trailing 90-day volume-weighted average closing stock price (“VWAP”) is $4.00, one-third of the PSUs vest when the VWAP is $6.00 and one-third when the VWAP is $8.00.  All PSUs will expire on April 1, 2023 if no performance metric is achieved.  The $1.0 million is being expensed over the respective derived service periods of each tranche of 16 months, 25 months and 30 months, respectively.  The respective fair value and derived service periods assigned to the PSUs were determined using a Monte Carlo model based on: the Company’s historical volatility of 55.9%, a term of 4.1 years, stock price on the date of grant of $2.50 per share, a risk-free rate of 2.5% and a cost of equity of 9.5%.
