Performance Share Units (“PSUs”)
Performance share units (“PSUs”) are grants that vest upon the achievement of certain performance goals. The goals are commonly related to the Company’s market capitalization or market share price of the common stock. The PSUs originally issued during 2015 to certain board members and senior management shall be earned based on the Company’s achievement of market capitalization growth between the effective date of the Employment Agreement and the end of the Initial Employment Period. If the Company’s market capitalization is $100 million or less, no PSUs will be earned. If the Company reaches a market capitalization of $1.1 billion or more, 100% of the PSUs will be earned. For market capitalization between $100 million and $1.1 billion, the percentage of PSUs earned will be determined on a quarterly basis based on straight line interpolation. The Company determined that the PSUs were equity awards with both market and service conditions. The Company utilized a Monte Carlo simulation to determine the fair value of the market condition, as described below. Grantees of PSUs are required to be employed through December 31, 2018 in order to earn the entire award, if and when vested. No PSUs were granted during the nine months ended September 30, 2017.
The fair value of the grants of PSUs to purchase a total of 1,342,061 shares of common stock (including 1,278,153 PSUs granted under the 2015 Performance Share Unit Plan and 63,908 granted as an inducement) was determined to be approximately $3,218,000, and is amortized over the service period of May 21, 2015 through December 31, 2018, on a straight-line basis. On October 24, 2016, the Compensation Committee granted Mr. Rizzone a PSU award under the 2013 Equity Incentive Plan under which Mr. Rizzone has the right to receive 150,000 shares of common stock. The shares of this award vest upon the Company’s stock price meeting specific targets. For the PSU award grant issued to Mr. Rizzone, a Monte Carlo simulation was used to determine the fair value at each of the five target prices of common stock, using a market capitalization of $298,857,000, dividend yield of 0%, expected volatility of 75% and a risk-free interest rate of 0.66%. The fair value of the PSUs granted to Mr. Rizzone under the 2013 Equity Incentive Plan was determined to be $2,332,000, and is amortized over the estimated service period from October 24, 2016 through October 30, 2017. Amortization for all PSU awards was $399,867 and $230,276 for the three months ended September 30, 2017 and 2016, respectively, and $1,601,160 and $673,405 for the nine months ended September 30, 2017 and 2016, respectively.

The first offering period started on January 1, 2016 and concluded on June 30, 2016. The second offering period started on July 1, 2016 and concluded on December 31, 2016. The weighted-average grant-date fair value of the purchase option for each designated share purchased under this plan was approximately $5.88 and $2.57 for the nine months ended September 30, 2017 and 2016, respectively, which represents the fair value of the option, consisting of three main components: (i) the value of the discount on the enrollment date, (ii) the proportionate value of the call option for 85% of the stock and (iii) the proportionate value of the put option for 15% of the stock. The Company recognized compensation expense for the plan of $79,046 and $266,398 for the three and nine months ended September 30, 2017, respectively, and $97,830 and $220,546 for the three and nine months ended September 30, 2016, respectively.
