Therefore, this line item includes all such performance-based restricted stock units granted during the three months ended September 30, 2018, reported at the maximum possible number of shares that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied (0.4 million shares for the three months ended September 30, 2018 reflects the application of the multiplier described above).
