Instead, this represents shares that have been withheld by the Issuer to satisfy its income tax and withholding and remittance obligations in connection with the vesting and net settlement of previously reported restricted stock awards, performance-based restricted stock awards, and restricted stock units. This Form 4 is amended because the shares in Column 4 were inadvertently understated as originally reported. /s/ Jeff True, Attorney-in-Fact for Rene Bonvanie 2019-04-25
