Footnotes from the filing
The reported transaction reflects the conversion of performance stock units to shares solely for the purpose of satisfying FICA tax withholding obligations as a result of the Reporting Person's retirement eligibility. The number of shares represents what was necessary to satisfy the FICA tax liability and related taxes attributable to the conversion itself, of which the shares were simultaneously forfeited to pay for the taxes.
