STOCK-BASED COMPENSATION:
CONSOL Energy adopted the CONSOL Energy Inc. Equity Incentive Plan on April 7, 1999. The plan provides for grants of stock-based awards to key employees and to non-employee directors. Amendments to the plan have been approved by the Board of Directors since the commencement of the plan. In 2012, the Board of Directors approved an increase in the total number of shares by 8,000,000 bringing the total number of shares of common stock that can be covered by grants to 31,800,000. At December 31, 2013, 6,072,413 shares are available for all awards. The Plan provides that the aggregate number of shares available for issuance under the Plan will be reduced by one share for each share issued in settlement of stock options. The Plan, as amended on May 1, 2012, provides the aggregate number of shares available for issuance under the Plan will be reduced by 1.62 for each share issued in settlement of Performance Share Units (PSUs), Restricted Stock Units (RSUs), or CONSOL Stock Units (CSUs). No award of stock options may be exercised under the plan after the tenth anniversary of the effective date of the award.
CONSOL Energy recognizes stock-based compensation costs for only those shares expected to vest on a straight-line basis over the requisite service period of the award, which is generally the option vesting term, or to an employee's eligible retirement date, if earlier and applicable. The total stock-based compensation expense recognized was $56,987, $41,127 and $42,131 for the years ended December 31, 2013, 2012 and 2011, respectively. The related deferred tax benefit totaled $21,769, $15,464 and $15,841, for the years ended December 31, 2013, 2012 and 2011, respectively.
CONSOL Energy examined its historical pattern of option exercises in an effort to determine if there were any discernable activity patterns based on certain employee populations. From this analysis, CONSOL Energy identified two distinct employee populations. CONSOL Energy uses the Black-Scholes option pricing model to value the options for each of the employee populations. The table below presents the weighted average expected term in years of the two employee populations. The expected term computation is based upon historical exercise patterns and post-vesting termination behavior of the populations. The risk-free interest rate was determined for each vesting tranche of an award based upon the calculated yield on U.S. Treasury obligations for the expected term of the award. The expected forfeiture rate is based upon historical forfeiture activity. A combination of historical and implied volatility is used to determine expected volatility and future stock price trends. There were no options granted in 2013. Total fair value of options granted during the years ended December 31, 2012 and 2011 were $8,515 and $9,913, respectively. The fair value of share-based payment awards was estimated using the Black-Scholes option pricing model with the following assumptions and weighted average fair values:

These stock options will expire ten years after the date on which they were granted. The employee stock options, covered by the Equity Incentive Plan adopted April 7, 1999, vest 25% per year, beginning one year after the grant date for awards granted prior to 2007. Employee stock options awarded after December 31, 2006, vest 33% per year, beginning one year after the grant date. There are 4,529,216 stock options outstanding under the Equity Incentive Plan. Additionally, there are 192,934 fully vested employee stock options outstanding which vested under terms ranging from six months to one year. Non-employee director stock options vest 33% per year, beginning one year after the grant date. There are 53,895 stock options outstanding under these grants. The vesting of all options, including performance options, will accelerate in the event of death, disability or retirement and may accelerate upon a change in control of CONSOL Energy.
The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between CONSOL Energy's closing stock price on the last trading day of the year ended December 31, 2013, and the option's exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2013. This amount varies based on the fair market value of CONSOL Energy's stock. Total intrinsic value of options exercised for the year ended December 31, 2013, 2012 and 2011 was $6,820, $18,562 and $18,049, respectively.
Cash received from option exercises for the years ended December 31, 2013, 2012 and 2011 was $3,720, $8,383 and $9,033, respectively. The tax impact from option exercises totaled $2,929, $8,678, and $8,281, for the years ended December 31, 2013, 2012 and 2011, respectively. This excess tax benefit is included in cash flows from financing activities in the Consolidated Statements of Cash Flows.
Under the Equity Incentive Plan, CONSOL Energy granted certain employees and non-employee directors restricted stock unit awards. These awards entitle the holder to receive shares of common stock as the award vests. Compensation expense is recognized over the vesting period of the units. The total fair value of the restricted stock units granted during the years ended December 31, 2013, 2012 and 2011 was $20,687, $26,426 and $24,882, respectively. The total fair value of shares vested during the years ended December 31, 2013, 2012 and 2011 was $37,002, $23,097 and $16,496, respectively.

Under the Equity Incentive Plan, CONSOL Energy granted certain employees performance share unit awards. These awards entitle the holder to receive shares of common stock subject to the achievement of certain market and performance goals. Compensation expense is recognized over the performance measurement period of the units in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification for awards with market and performance vesting conditions. At December 31, 2013, achievement of the market and performance goals is believed to be probable. The total fair value of performance share units granted during the years ended December 31, 2013, 2012 and 2011 was $1,270, $16,794 and $11,648, respectively.
