Stock Based Compensation [Abstract]  
Assumptions used to value the options granted
The Company estimates fair value of stock options using the Black-Scholes valuation model.  Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield.  The fair value of the options granted during the nine months ended September 30, 2013 and 2012 and the related assumptions used in the Black-Scholes option model used to value the options granted were as follows:
