Share-Based Compensation
10. Share-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation,” which requires the Company to recognize compensation expense for stock-based awards, measured at the fair value of the awards at the grant date. The Company recognized expense of approximately $375,000 and $158,000 during the quarters ended March 31, 2014 and 2013, respectively.

 

The weighted-average fair value of stock options granted during the three months ended March 31, 2014 was estimated at $7.77 per option using the Black-Scholes option-pricing model based on the following assumptions:

Expected Volatility: The Company utilizes a volatility factor based on the Company’s historical stock prices for a period of time equal to the expected term of the stock option utilizing weekly price observations. For the three months ended March 31, 2014, the Company utilized a weighted-average volatility factor of 57%.

Expected Term: For the three months ended March 31, 2014, the Company utilized a weighted-average expected term factor of 6.4 years.

Risk-Free Interest Rate: The risk-free interest rate factor utilized is based upon the implied yields currently available on U.S. Treasury zero-coupon issues over the expected term of the stock options. For the three months ended March 31, 2014, the Company utilized a weighted-average risk-free interest rate factor of 2.3%.

Expected Dividends: The Company utilized an expected dividend rate of 1.3% to value options granted during the three months ended March 31, 2014.

The Company did not grant any stock options during the three months ended March 31, 2013.

The fair value of the stock options granted is recorded as compensation expense on a straight-line basis over the vesting periods of the options adjusted for the Company’s estimate of pre-vesting forfeitures. The pre-vesting forfeiture estimate is based on historical activity and is reviewed periodically and updated as necessary.

The Company received $0.5 million and $0.1 million in cash from employees and directors exercising options during the three months ended March 31, 2014 and 2013, respectively. The intrinsic value of options exercised during the three months ended March 31, 2014 and 2013 was $1.0 million and $0.1 million, respectively.
