Share-based Compensation

Stock Options—The Company accounts for compensation expense associated with stock options issued to employees, Directors, and non-employees based on their fair value, which is calculated using an option pricing model, and is recognized over the service period, which is usually the vesting period. At December 31, 2013, the Company has one equity based compensation plan. No stock options were granted to employees or non-employees during 2013, 2012 and 2011; however, options were granted to Directors in 2013, 2012 and 2011. Stock compensation expense of $474 thousand, $539 thousand and $537 thousand was recognized during the years ending December 31, 2013, 2012 and 2011, respectively, on outstanding and unvested options.

The fair value of options granted during 2013 is estimated on the date of grant using the Black-Scholes option pricing model. The following table includes the weighted- average assumptions used in estimating the fair values and the resulting weighted-average fair value of stock options granted in the periods presented:



	Year Ended December 31, 2013			Year Ended December 31, 2012			Year Ended December 31, 2011
