(4)Share-Based Compensation

Share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as an expense over the requisite service period (generally the vesting period of the equity grant).

The Company issues share-based awards through several plans that are described in detail in the notes to the consolidated financial statements for the year ended December 31, 2014. The compensation cost charged against income for those plans is included in selling, general & administrative expenses as follows (in thousands):

	2015		2014		2015		2014
Total share-based compensation expense	$	436	$	465	$	647	$	730

Share-based compensation for the three-month periods ended June 30, 2015 and 2014 includes approximately $105,000 and $122,000, respectively, representing the fair value of the Company’s common stock granted during the periods to the Board of Directors. Share-based compensation for the six-month periods ended June 30, 2015 and 2014 includes approximately $105,000 and $127,000, respectively, representing the fair value of the Company’s common stock granted during the periods 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, 2015:

	Shares Under Options		Weighted Average Exercise Price (per share)		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2014	340,107		$	12.84
Granted	17,526		19.97
Exercised	(43,758	)	5.09

Outstanding at June 30, 2015	313,875		$	14.32	3.99	$	2,227

Exercisable at June 30, 2015	250,126		$	12.67	4.22	$	2,153

Vested and expected to vest at June 30, 2015	313,875		$	14.32	3.99	$	2,227

On June 10, 2015, the Company granted options to its directors for the purchase of 17,526 shares of common stock at that day’s closing price of $19.97. 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	32.3	%
Expected dividends	None
Risk free interest rate	1.0	%
Expected term	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, 2015 was $5.99.

During the six-month periods ended June 30, 2015 and 2014, 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 $696,000 and $3.4 million, respectively, and the total amount of consideration received by the Company from the exercised options was approximately $223,000 and $675,000, respectively.
