For the six month periods ended June 30, 2013 and 2012, the Company did not recognize any compensation expense related to its stock option plans. Expense is recognized ratably over the five-year vesting period of the options. At June 30, 2013, there was no unrecognized compensation expense related to nonvested stock options to be recognized over the remaining vesting period. The Black-Scholes option pricing model was used to determine the fair value of the options granted in prior periods.
