At inception, there were 0.21 million shares of the Company’s common stock available for issuance under the 2016 Plan.

Compensation cost for restricted stock is measured as the excess, if any, of the quoted market price of the Company’s stock at the date the common stock is issued over the amount the employee must pay to acquire the stock (which is generally zero). Compensation cost is recognized over the period between the issue date and the date any restrictions lapse, with compensation cost recognized on a straight-line basis over the requisite service period. The restrictions do not affect voting and dividend rights.
