[1] PSU adjustment represents the net RSUs awarded to our NEOs above and below their target grants resulting from the achievement of performance goals above or below the performance targets established at grant. One grant goal was achieved at 50% and another grant goal was forfeited for performance equity awards whose final achievement was based on Fiscal 2017 through Fiscal 2019 financial results; therefore, the adjustment was negative.
