Share-Based Compensation |
Share-Based Compensation | (4) Share-Based Compensation Share-based compensation cost is measured at the grant date based on the calculated fair value of the award and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grant). The Company issues share-based payments through several plans that are described in detail in the notes to the consolidated financial statements for the year ended December 31, 2012. The compensation cost charged against income for those plans is as follows:
|  | Three Months Ended |  | Nine Months Ended |
|  | September 30, |  | September 30, |
|  | 2013 |  | 2012 |  | 2013 |  | 2012 |
Selling, general & administrative expense |  | $ | 199,967 |  | $ | 182,286 |  | $ | 707,453 |  | $ | 679,340 |
Share-based compensation for the nine-month periods ended September 30, 2013, and 2012, includes approximately $60,000 representing the fair value of the Company’s stock granted to the Board of Directors. The total income tax benefit recognized in the condensed consolidated statements of income for share-based compensation arrangements was approximately $58,000 and $55,000 for the three-month periods ended September 30, 2013, and 2012, respectively, and approximately $215,000 and $227,000 for the nine-month periods ended September 30, 2013, and 2012, respectively. The following is a summary of stock option activity under all plans for the nine-month period ended September 30, 2013:
|  | Shares Under Options |  | Weighted Average Exercise Price |  | Aggregate Intrinsic Value |
Outstanding at December 31, 2012 |  | 493,888 |  | $ | 5.47 |  |  |
Granted |  | 97,362 |  | 19.74 |  |  |
Exercised |  | (117,500 | ) | 2.85 |  |  |
Cancelled or expired |  | — |  | — |  |  |
Outstanding at September 30, 2013 |  | 473,750 |  | $ | 9.05 |  | $ | 6,498,890 |
Options exercisable at September 30, 2013 |  | 367,500 |  | $ | 6.31 |  | $ | 6,048,878 |
Vested and expected to vest at September 30, 2013 |  | 473,750 |  | $ | 9.05 |  | $ | 6,498,890 |
On March 31, 2013, the Company granted to certain employees options for the purchase of 60,000 shares of its common stock at that day’s closing price of $18.85. On June 12, 2013, the Company granted to its directors options for the purchase of 7,362 shares of common stock at that day’s closing price of $19.08. On September 12, 2013, the Company granted to a certain employee options for the purchase of 30,000 shares of common stock at that day’s closing price of $21.67. The compensation expense for the above noted grants was determined as the fair value of the options using the Black Scholes option pricing model based on the following assumptions:
Expected volatility | 34.0% - 50.0%
Expected dividends | none
Risk free interest rate | 0.4% - 0.7%
Expected term | 3.3 to 5.0 years
The stock volatility for each grant is determined based on a review of the experience of the weighted average of historical daily price changes of the Company’s common stock over the expected option term, and the risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The weighted average grant date fair value of options granted during the nine-month period ended September 30, 2013, was $5.84. During the nine-month periods ended September 30, 2013, and 2012, the total intrinsic value of all options exercised (i.e., the difference between the market price on the exercise date and the price paid by the employees to exercise the options) was $2,070,527 and $2,028,138, respectively, and the total amount of consideration received from the exercised options was $334,475 and $491,036, respectively. During the three-month periods ended September 30, 2013, and 2012, the Company recognized compensation expenses related to stock options granted to directors and employees of $40,178 and $18,186, respectively.
