-BASED COMPENSATION PLANS

The Company has stock incentive plans for executives and eligible employees. Stock awards include stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, and performance share units. Share-based compensation expense for the years ended December 31, 2013, 2012, and 2011 was $4.8 million, $8.0 million, and $8.1 million, respectively. At December 31, 2013, there was $7.0 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.7 years.

Stock Options and Stock Appreciation Rights

Stock options and stock appreciation rights (SARs) granted under the Company’s incentive plans vest over three years and are exercisable over a period not to exceed ten years from the grant date. The exercise price of the stock options and SARs is equal to the fair market value of the shares on the date of the grant. The value of each stock option award and SAR is estimated using the Black-Scholes option pricing model. Stock options are accounted for as equity awards and SARs are accounted for as liability awards and remeasured at each reporting date. SARs, when vested, provide the participant the right to receive cash equal to the excess of the market price of the shares over the exercise price when exercised. Cash used to settle SARs for the years ended December 31, 2013, 2012 and 2011 was $0.0 million, $0.4 million and $1.9 million, respectively.

The following table sets forth the weighted average fair value of stock options and the assumptions used to estimate the fair value of the stock options using the Black-Scholes option valuation model:

Restricted Stock and Restricted Stock Units

Restricted stock and restricted stock units granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant and vest in equal installments annually over three years. Restricted stock awards are accounted for as equity awards and restricted stock unit awards are accounted for as liability awards. Restricted stock units are remeasured at each reporting date. Restricted stock units are settled in cash based on the number of vested restricted stock units multiplied by the current market price of the common shares when vested. Holders of the restricted stock are entitled to vote the shares and to receive any dividends declared on the shares. Cash used to settle restricted stock units for the years ended December 31, 2013, 2012, and 2011 was $0.2 million, $0.9 million, and $2.2 million, respectively.

Performance Shares and Performance Share Units

Performance shares and performance share units granted under the Company’s incentive plans are accounted for at fair value. Performance share awards are accounted for as equity awards and performance units are accounted for as liability-based awards. Performance shares and performance units are valued using a Monte Carlo simulation valuation model on the date of grant. The value of the performance units is remeasured each reporting date. Vesting is contingent on meeting certain market conditions based on relative total stockholder return. The performance shares and units vest at the end of the three-year service period if market and service conditions are met. The existence of a market condition requires recognition of compensation cost for the performance share awards over the requisite period regardless of whether the market condition is satisfied. Performance units are cash-based awards and are settled in cash based on the current market price of the common shares when vested. Cash used to settle performance units for the years ended December 31, 2013, 2012, and 2011 was $1.2 million, $2.1 million, and $1.4 million, respectively.

The following table summarizes performance shares and performance units’ activity for the years-ended December 31, 2013, 2012, and 2011:
