Stock-Based Incentive Plans |
Stock-Based Incentive Plans | 8. Stock-Based Incentive Plans The Company currently has one stock-based incentive plan, which incorporates and supersedes its two previous plans (see Note 1 “Basis of Presentation — Accounting for Stock-Based Compensation”). Participants are granted stock-based awards only if the applicable Company-wide or profit-center operating goals, or both, established by the Compensation and Leadership Development Committee of the Board of Directors at the beginning of the year, are met. Certain participants may have additional goals based on strategic initiatives of the Company. The fair value of each restricted stock unit award is estimated on the date of the award based on the closing market price of the underlying stock on the day preceding the date of the award. On February 6, 2013, 359,371 restricted stock units were awarded, including 9,975 awarded to the Company’s directors who are not employees, at an estimated value of $31.96 per share, based on the closing price on February 5, 2013. The restrictions on these awards generally lapse one quarter on the date of the award and one quarter on each of the first, second and third anniversaries of the date of the award. The following table summarizes the Company’s unvested restricted stock unit activity for the six months ended June 30, 2013:
|  |  |  |  |  | Aggregate |
|  |  |  | Weighted- |  | Intrinsic |
|  | Shares |  | Average |  | Value * |
Unvested Restricted Stock Units (RSUs) |  | (in thousands) |  | Price |  | (in thousands) |
Outstanding at January 1, 2013 |  | 264 |  | $ | 33.23 |  |  |
Awarded |  | 359 |  |  |  |  |
Vested |  | (169 | ) |  |  |  |
Forfeited |  | (1 | ) |  |  |  |
Outstanding at June 30, 2013 |  | 453 |  | $ | 32.45 |  | $ | 13,339 |
Outstanding and expected to vest at June 30, 2013 |  | 442 |  | $ | 32.45 |  | $ | 12,993 |
* The intrinsic value is calculated using the closing price per share of $29.42 as reported by the New York Stock Exchange on June 28, 2013. Based on the market value on the award date, the total intrinsic value of vested restricted stock units during the six-month periods ended June 30, 2013 and 2012, was $5.5 million and $3.1 million, respectively. The fair value of each stock option grant was estimated on the date of grant using the Black-Scholes option pricing model. Expected volatility was based on historical volatilities of the Company’s common stock measured monthly over a term that is equivalent to the expected life of the stock option. The expected term of each stock option was estimated based on the Company’s prior exercise experience and future expectations of the exercise and termination behavior of the grantees. The risk-free rate was based on the yield of United States Treasury zero-coupon bonds with maturities comparable to the expected life in effect at the time of grant. The dividend yield was based on the expected dividend yield on the grant date. No stock options were granted in 2012 or the first half of 2013. The following table summarizes the Company’s stock option activity for the six months ended June 30, 2013:

* The intrinsic value represents the amount, if any, by which the fair market value of the underlying common stock exceeds the exercise price of the stock option, using the closing price per share of $29.42 as reported by the New York Stock Exchange on June 28, 2013. The total intrinsic value of stock options exercised during the six-month periods ended June 30, 2013 and 2012, was $0.2 million and $0.7 million, respectively. A summary of the status of unvested stock options as of June 30, 2013, and changes during the six months ended June 30, 2013, are presented below:
