Share-based compensation for the three-month periods ended June 30, 2014 and 2013 includes approximately $122,000 and $60,000, respectively, representing the fair value of the Company’s common stock granted during the quarter to the Board of Directors. Share-based compensation for the six-month periods ended June 30, 2014 and 2013 includes approximately $127,000 and $60,000, respectively, representing the fair value of the Company’s common stock granted during the period to the Board of Directors.

The following is a summary of stock option activity under all plans for the six-month period ended June 30, 2014:

Outstanding at December 31, 2013	467,500		$	9.00

Exercised	(159,336	)	4.23

On March 12, 2014, the Company granted one of its directors options to purchase 577 shares of its common stock at that day’s closing price of $25.48. On June 11, 2014, the Company granted options to certain employees and directors for the purchase of 15,000 shares and 14,616 shares, respectively, of common stock at that day’s closing price of $25.04. The compensation expense related to these grants was determined as the fair value of the options using the Black Scholes option pricing model based on the following assumptions:

Expected volatility	32.8% to 37.9%
Expected dividends	None
Risk free interest rate	0.7% to 0.8%
Expected term	3.8 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 six-month period ended June 30, 2014 was $7.47.

During the six-month periods ended June 30, 2014, and 2013, 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 approximately $3.4 million and $155,000, respectively, and the total amount of consideration received by the Company from the exercised options was approximately $675,000 and $65,000, respectively. At its discretion, the Company allows option holders to surrender previously owned common stock in lieu of paying the exercise price and withholding taxes. During the six-months ended June 30, 2014, 31,310 shares (14,077 for options and 17,233 for taxes) were surrendered at an average market price of $25.47.
