Share-Based Compensation [Abstract] |
SHARE-BASED COMPENSATION | 10. SHARE-BASED COMPENSATION Stock Options: The Company has issued non-qualified and incentive stock options to employees and nonemployee directors. The fair value of these options are estimated on the date of grant using the Black-Scholes option pricing model, which requires estimates of the expected term of the option, the expected volatility of the price of the Company’s common stock, dividend yield and the risk-free interest rate. Options outstanding as of December 31, 2014 vest over a period of three years with an expiration term of ten years. The exercise price of these options ranges from $24.26 to $28.81. The expected volatility is based on the historical volatility of the Company’s common stock over the period of time equivalent to the expected term for each award. Due to the Company’s lack of option exercise history, the expected term is calculated using the simplified method defined as the midpoint between the vesting period and the contractual term of each award. The risk free interest rate is based on the U.S. Treasury yield curve in effect on the date of grant which most closely corresponds to the expected term of the option. The Company historically has not issued dividends and therefore does not utilize a dividend yield in the calculation. The weighted average input assumptions used and resulting fair values were as follows:
|  | 2014 |  | 2013 |
Expected life (in years) |  | 6 |  | - |
Risk-free interest rate |  | 1.61 | % | - |
Expected volatility |  | 63.15 | % | - |
Dividend yield |  | - |  | - |
The following table summarizes the stock option activity:

The weighted-average grant date fair value of options granted was $15.19. The unrecognized compensation expense calculated under the fair value method for shares expected to vest as of December 31, 2014 was approximately $0.6 million and is expected to be recognized over a weighted average period of 1.9 years. Restricted Stock: The Company has issued restricted stock to employees and nonemployee directors generally with terms ranging up to seven years. The fair value is equal to the market price of the Company’s common stock on the date of grant. Expense for restricted stock is amortized ratably over the vesting period. The following table summarizes the restricted stock activity:
|  |  | Weighed-Average |
|  |  | Shares |  | Grant Date Fair Value |
Unvested at December 31, 2013 |  |  | 393,532 |  | $ | 24.23 |
Granted |  |  | 23,115 |  |  | 28.43 |
Vested |  |  | (119,388) |  |  | 23.68 |
Forfeited |  |  | (7,333) |  |  | 28.81 |
Unvested at December 31, 2014 |  |  | 289,926 |  | $ | 25.13 |
The total share-based compensation expense charged against income during the years ended December 31, 2014, 2013, and 2012 were $3,918,000, $3,209,000, and $2,850,000, respectively. In addition to the unvested shares listed above, the Company recognized $734,000 in share-based compensation in 2014 for 43,750 shares of performance awards to be issued to certain key employees based on achieving 2014 financial plan that will vest on December 31, 2015. The Company intends to issue additional performance awards in 2015 to certain key employees if certain 2015 financial plans are met. During 2014, the Company issued 7,000 restricted stock awards to certain key employees vesting over 3 - 4 years. The Company issued additional awards to members of the Board of Directors including: 6,850 shares to vest over a one year period and 9,265 granted in lieu of meeting fees that vested immediately. The total income tax benefit recognized in the consolidated statement of income for these restricted stock awards was approximately $1,398,000, $1,123,000 and $969,000 for the years ending December 31, 2014, 2013, and 2012, respectively. The tax benefit recognized in additional paid-in capital upon vesting of restricted stock awards was approximately $275,000, $383,000 and $1,265,000 for the years ending December 31, 2014, 2013, 2012, respectively. There was approximately $5.8 million of total unrecognized compensation cost related to restricted stock awards as of December 31, 2014. The cost is expected to be recognized over a weighted-average period of approximately 3.1 years.
