The weighted-average grant date fair value of performance-based restricted stock units is based on the quoted
market price of our common stock on the date of grant. The weighted-average grant date fair values of
performance-based restricted stock units granted during fiscal year 2011 was $15.39. The total grant date fair
values of performance-based restricted stock units that vested during fiscal year 2013 was less than $1 million.
No performance-based restricted stock units vested during fiscal years 2012 and 2011.
Market-Based Restricted Stock Units
Our market-based restricted stock units vest contingent upon the achievement of pre-determined market and
service conditions. If these market conditions are not met but service conditions are met, the restricted stock units
will not vest; however, any compensation expense we have recognized to date will not be reversed. The number
of shares of common stock to be received at vesting will range from zero percent to 200 percent of the target
number of stock units based on our total stockholder return ("TSR") relative to the performance of companies in
the NASDAQ-100 Index for each measurement period, generally over a three year period. We present shares
granted at 100 percent of target of the number of stock units that may potentially vest. The maximum number of
common shares that could vest is approximately 1.9 million for market-based restricted stock units granted in the
fiscal year 2013. As of March 31, 2013, the maximum number of shares that could vest is approximately
1.9 million for market-based restricted stock units outstanding.
