estimated weighted-average amortization period of 49 months. The grant-date fair value of shares granted was $12.3 million, $12.2 million and $10.6 million in 2013, 2012 and 2011, respectively and we have recognized compensation expense of $10.3 million, $9.9 million and $12.4 million in 2013, 2012 and 2011, respectively. The total grant-date fair value, which is the intrinsic value of the shares, vested was $9.9 million, $10.3 million and $8.4 million in 2013, 2012 and 2011, respectively. We have recognized a tax benefit from the vesting of the RSAP of $3.0 million, $3.9 million and $2.6 million in 2013, 2012 and  2011, respectively. The Director Plan provides common shares for grant to our eligible Supervisory Directors. The maximum number of shares available  for award under this plan is 1,400,000 common shares. As of December 31, 2013 approximately 567,199 shares remained available  for issuance under the Director Plan. On June 28, 2006, the 1995 Non-employee Director Stock Option Plan was amended, restated  and renamed as the 2006 Non-employee Director Stock Incentive Plan. The primary change effected by the 2006 amendment  was to eliminate the automatic, formula grant of stock options under the prior plan and to replace that formula approach with the  discretionary right of the Supervisory Board to grant stock options, restricted shares, or any combination thereof. Only non-employee  Supervisory Directors are eligible for these equity-based awards under the Director Plan. In 2011, the Compensation Committee of our Board of Supervisory Directors approved the RSAP to compensate our non-employee  Supervisory Directors. Under this arrangement we awarded grants totaling 7,616 shares, 7,987 shares and 10,283 shares in 2013,  2012, and 2011, respectively. Each of these grants has a vesting period of 3 years. There are no performance accelerators for early  vesting for these awards. Awards under the RSAP are classified as equity awards and recorded at the grant-date fair value with  compensation expense recognized over the expected life of the award. As of December 31, 2013, there was $1.2 million of unrecog- nized total stock-based compensation relating to non-vested RSAP awards. The unrecognized compensation expense is expected to  be recognized over an estimated weighted-average amortization period of 22 months. The grant-date fair value of shares granted was  $1.0 million, $1.0 million and $1.0 million in 2013, 2012, and 2011, respectively, and we have recognized compensation expense of  $0.7 million, $0.6 million and $0.2 million in 2013, 2012, and 2011, respectively. Non-vested restricted share awards outstanding under both the 2007 Long-term Incentive Plan and the 2006 Non-employee Director  Stock Incentive Plan as of December 31, 2013 and changes during the year were as follows: (Shares stated in thousands) Number of Shares Weighted Average  Grant Date Fair  Value per Share Non-vested at December 31, 2012 634,310 $ 89.42 Granted 181,896 129.29 Vested (222,176) 80.56 Forfeited (30,695) 82.16 Non-vested at December 31, 2013 563,335 $ 105.58 57 2006 Non-employee Director Stock Incentive Plan Restricted Share Award Program
