[1] The Company includes only the target number of PBRSUs in the granted amount. During the period, actual performance results exceeded target for certain PBRSUs, resulting in incremental shares being earned. These additional shares are presented separately as “Performance adjustment” to reflect the impact of the above-target performance.
