The restrictions will lapse and the units will vest in three installments as follows: 1,954 shares on January 16, 2012; 1,954 shares on January 16, 2013; and 1,954 shares on January 16, 2014 (contingent upon the officer's employment on the scheduled vesting dates). Each restricted stock unit represents the right to receive one share of common stock; however, the Management Development and Compensation Committee of the Company may settle the restricted stock units in cash if insufficient shares are available at the end of the restriction periods.
(2) The options are non-qualified and have a ten-year term starting January 17, 2011. The options will vest in four equal installments as follows: 4,795 shares on January 17, 2011; 4,795 shares on January 17, 2012; 4,795 shares on January 17, 2013; and 4,795 shares on January 17, 2014. Each stock option entitles the holder to purchase one share of AWI common stock at an exercise price equal to $42.65, which may be paid in cash or by delivering shares of AWI stock the holder has owned for at least six months.
