(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.
