# FY05 Executive
Incentive Grid (Share in Success Plan)

The grid is designed to reward
achievement of plan on both metrics (Pre-tax Profitability and Revenue), and to discourage
the achievement of one metric at the expense of the other. If threshold performance is not
achieved on either metric, the payout is nil. There is a cap of 400% on the overall level
of payout.
