	Performance Condition Achievement Level		Number of Shares underlying PSUs
	Constellium TSR is below the average of the two 25^th percentile TSRs of the Comparator Group		PSU Base Amount x 0%
	Constellium TSR is at the average of the two 25^th percentile TSRs of the Comparator Group		PSU Base Amount x 25%
	Constellium TSR is between the average of the two 25^th percentile TSRs & the average of the two median TSRs of the Comparator Group		PSU Base Amount x (linear interpolation between 25% and 100%)
	Constellium TSR is at the average of the two median TSRs of the Comparator Group		PSU Base Amount x 100%
	Constellium TSR is between the average of the two median TSRs & the average of the two 75^th percentile TSRs of the Comparator Group		PSU Base Amount x (linear interpolation between 100% and 200%)
	Constellium TSR is at or above the average of the two 75^th percentile TSRs of the Comparator Group		PSU Base Amount x 200%
