[1] | 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”)
[2] | 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%.

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. + References Reference 1: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 718 -SubTopic 10 -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -URI http://asc.fasb.org/extlink&oid=120381028&loc=d3e5070-113901 + Details
