Stock-Based Compensation Expense
Since the completion of the CHS Transactions on April 30, 2010, the board of directors has adopted and the shareholders have approved two stock option award plans. The 2010 Thermon Group Holdings, Inc. Restricted Stock and Stock Option Plan (“2010 Plan”) was approved on July 28, 2010. The 2010 Plan authorized the issuance of 2,767,171 stock options or restricted shares (on a post-stock split basis). On April 8, 2011, the board of directors approved the Thermon Group Holdings, Inc. 2011 Long-Term Incentive Plan (“2011 LTIP”). The 2011 LTIP made available 2,893,341 shares of the Company’s common stock that may be awarded to employees, directors or non-employee contractor's compensation in the form of stock options or restricted stock awards.
At September 30, 2013, there were 898,461 options outstanding. For the three months ended September 30, 2013 and 2012, stock compensation expense was $544, and $336, respectively, and $910 and $394 for the six months ended September 30, 2013 and 2012, respectively.
During the six months ended September 30, 2013, we issued various stock compensation awards to our directors and employees. During the six months ended September 30, 2013, 117,904 restricted stock units were granted to certain of our employees. On August 1, 2013, 17,416 restricted stock awards were issued to our directors and a target amount of 43,554 performance stock units were granted to our named executive officers. The closing price on the date of the grants ranged from $19.48 to $22.02.
The restricted stock units that were issued to our employees have a total fair value of $2,375 as determined by the closing price of our stock on the date of the grants. The awards will be expensed on a straight-line basis over the service period which ranges from 3 to 5 years. At each anniversary of the restricted stock units' grant date, a proportionate number of restricted stock units will become vested for the employees and the shares will become issued and outstanding.
The restricted stock awards issued to our directors have a total fair value of $350 as determined by the closing price of our stock on August 1, 2013 and will be expensed on a straight-line basis over one year. The stock associated with the directors' awards has already been issued and is included in our shares outstanding with voting rights. On the anniversary of the grant date, the restricted stock will fully vest.
The performance stock units issued to our four named executive officers have a total fair value at grant date of $480. The performance indicator for these stock awards is based on the market performance of our stock price as compared to a pre-determined peer group of companies with similar business characteristics as ours. Since the performance indicator is market based, we prepared a Monte Carlo valuation model to calculate the probable outcome of the performance measure to arrive at fair value. We will expense the fair value over three years at each of our fiscal year ends during the performance period, whether or not the market condition is met. At the end of each fiscal year, one-third of the performance units will be evaluated. It will then be determined how many shares will be issued. In each year, the possible number of shares that will be issued ranges from zero to 87,108 in aggregate. Shares that are not awarded in a given year will be forfeited.
