(1) The number of shares for 62,791 of the PSUs included in the outstanding balance at January 1, 2020 represents the actual number of PSUs granted to each recipient that are eligible to vest if the Company meets its performance goals for the applicable period. The number of shares for the remainder of the PSUs included in the outstanding balance at January 1, 2020 and for all of the PSUs granted in 2020 represents the “target” number of PSUs granted to each recipient eligible to vest if the Company meets its “target” performance goals for the applicable period. The actual number of PSUs eligible to vest for those PSUs will vary depending on whether or not the Company meets or exceeds the applicable threshold, target, or maximum performance goals for the PSUs, with 200% of the “target” number of PSUs eligible to vest at “maximum” performance levels.
