(1) Amount includes 2,423 shares of restricted stock units (RSUs) awarded on February 3, 2014. RSUs vest one fourth on each of the award date and the first, second and third anniversaries of the award date. The 2,423 shares are net of the number of shares expected to be withheld to cover the estimated income taxes due on vesting.
(2) Amount includes 2,173 shares of restricted stock units (RSUs) awarded on February 6, 2013. RSUs vest one fourth on each of the award date and the first, second and third anniversaries of the award date. The 2,173 shares are net of the number of shares expected to be withheld to cover the estimated income taxes due on vesting.
(3) Amount includes 2,923 shares of restricted stock units (RSUs) awarded on January 30, 2012. RSUs vested one fourth on each of the award date and the first, second and third anniversaries of the award date. Amount was increased by 5 shares to reflect the difference between the number of shares that was expected to be withheld to cover the estimated income taxes due on vesting (estimated on January 30, 2012, the date of the award) and the actual number of shares that was withheld on vesting of the RSUs.
