The EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan, as amended (2008 Plan), provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock, restricted stock units, performance units, performance stock and other stock-based awards. At March 31, 2013, approximately 3.2 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to the 2008 Plan from either previously authorized unissued shares or treasury shares to the extent treasury shares are available. At the 2013 Annual Meeting of Stockholders, EOG's stockholders approved the Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (Plan). As more fully discussed in the Plan document, the Plan, among other things, authorizes an additional 15,500,000 shares of EOG common stock for grant under the Plan and extends the expiration date of the Plan to May 2023. Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $10.4 million and $10.9 million during the three months ended March 31, 2013 and 2012, respectively. Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the three-month periods ended March 31, 2013 and 2012 are as follows:
|  | Stock Options/SARs |  |  | ESPP |
|  | Three Months Ended |  |  | Three Months Ended |
|  | March 31, |  |  | March 31, |
|  | 2013 |  |  | 2012 |  |  | 2013 |  |  | 2012 |
Weighted Average Fair Value of Grants |  | $ | 38.61 |  |  | $ | 37.97 |  |  | $ | 28.80 |  |  | $ | 28.24 |
Expected Volatility |  |  | 35.54 | % |  |  | 41.11 | % |  |  | 29.95 | % |  |  | 46.42 | %
Risk-Free Interest Rate |  |  | 0.50 | % |  |  | 0.49 | % |  |  | 0.12 | % |  |  | 0.06 | %
Dividend Yield |  |  | 0.6 | % |  |  | 0.6 | % |  |  | 0.6 | % |  |  | 0.6 | %
Expected Life |  | 5.6 yrs. |  |  | 5.6 yrs. |  |  | 0.5 yrs. |  |  | 0.5 yrs. |
Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants. EOG RESOURCES, INC.
