STOCKHOLDERS' EQUITY
NOTE 11. STOCKHOLDERS’ EQUITY
Stock-Based Compensation
     At the end of the second quarter of 2011, there were 2.3 million shares reserved for issuance under various incentive plans. The Company’s Director Stock Unit Plan allows the Company to pay its non-employee directors annual retainer fees and, at their election, meeting fees in the form of stock units. Employee and director stock units are included in common stock outstanding on the date of vesting and stock options are included in common stock outstanding upon exercise by the participant. The fair value of stock options and stock units is amortized over the respective vesting period representing the requisite service period.
     The Company granted approximately 0.2 million stock units to employees during the six months ended July 1, 2011. The weighted-average grant-date fair value of the employee stock units was $69.91. During the six months ended July 1, 2011, the Company granted directors 18,679 stock units with a weighted-average grant-date fair value of $64.80. The Company granted approximately 0.1 million stock options to employees during the six months ended July 1, 2011 that had a weighted-average grant-date fair value of $28.50 and a weighted-average exercise price of $69.54. The fair value of the stock options granted during the six months ended July 1, 2011 was estimated using the Black-Scholes option pricing model with the following assumptions:
             
Expected Stock   Risk-Free Interest   Expected Dividend   Average Expected
Price Volatility   Rate   Yield   Life
38%
  2.2% to 2.5%   0%   6.13 years
