The total award will be earned, if at all, in four increments as follows, 15,112 shares, 3,148 shares, 6,926 shares, 6,297 shares, if the average daily closing price of the Company's common stock on the NASDAQ Global Market during any consecutive thirty-day period exceeds $48.00, $50.00, $55.00, and $60.00, respectively. This amount reflects the vesting of restricted stock (RSU) that vested on March 8, 2015, upon which date the reported closing price of the Company's common stock price exceeded an average of $50 for the preceding 30 calendar days.
(2)	These shares were deducted to cover tax withholding obligations associated with the restricted stock award vesting on March 8, 2015.
