Share Based Compensation | 4. Share Based Compensation The Company has Stock Incentive Plans (the Plans) pursuant to which the Company’s board of directors may grant stock options or restricted stock to employees. The Company is authorized to issue grants of restricted stock and stock options to purchase up to 26,963,150 shares as of June 30, 2014 and December 31, 2013. There were 6,930,787 additional shares remaining available for grant under the Plans at June 30, 2014. The table below summarizes the expense recognized related to share-based payments recognized for the three and six month periods ended June 30 (in thousands):
The tax benefits recorded on stock based compensation were $6.2 million and $2.7 million for the six month periods ended June 30, 2014 and 2013, respectively. The following table summarizes the Company’s total unrecognized compensation related to stock-based compensation as of June 30, 2014 (in thousands):
Stock Options Stock options are granted with an exercise price estimated to be equal to the fair market value on the date of grant as authorized by the Company’s board of directors. Options granted have vesting provisions ranging from one to six years. Certain stock option awards also have performance vesting provisions. Stock option grants are generally subject to forfeiture if employment terminates prior to vesting. The following summarizes the changes in the number of shares of common stock under option for the six month period ended June 30, 2014 (shares and aggregate intrinsic value in thousands):
The aggregate intrinsic value of stock options exercisable at June 30, 2014 was $274.0 million. The weighted average contractual term of options exercisable at June 30, 2014 was 5.7 years. The fair value of stock option awards granted was estimated using the Black-Scholes option pricing model during the three months ended June 30, 2014 and 2013, with the following weighted-average assumptions for grants during the period.
Restricted Stock Awards of restricted stock and restricted stock units are independent of stock option grants and are generally subject to forfeiture if employment terminates prior to vesting. The vesting of the restricted stock and restricted stock units granted is generally based on the passage of time, performance or market conditions. Shares vesting based on the passage of time have vesting provisions ranging from one to four years. The fair value of restricted stock granted based on market conditions was estimated using the Monte Carlo option pricing model at the grant date. The risk-free interest rate and volatility assumptions for restricted stock shares granted with market conditions were calculated consistently with those applied in the Black-Scholes options pricing model utilized in determining the fair value of the stock option awards. No such awards were granted during the six months ended June 30, 2014 and 2013. The following table summarizes the changes in the number of shares of restricted stock and restricted stock units for the six months ended June 30, 2014 (shares in thousands):
