About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F1: This award vests at the end of a three-year performance period that began on January 1, 2023 and ends on December 31, 2025 (the "Performance Period"). This award survives termination of employment due to death, disability, termination by the Company without cause or retirement by the employee upon having reached 62 years of age. In all cases, the shares will vest, if at all, at the end of the Performance Period as follows: 50% of the award will vest if the Company is in the top 35th percentile of Return on Invested Capital (ROIC) among the Bloomberg Peer Group (BPG), 100% of the award will vest if the Company is in the top 55th percentile of ROIC of the BPG, and 175% of the award will vest if the Company is in the top 85th percentile of ROIC of the BPG, as measured and determined by the Compensation Committee at the end of the Performance Period.

F2: The number of common shares vesting pursuant to the award will be interpolated on a straight-line basis between the 35th and 55th percentile (equivalent to 50% up to 100% of the award) and again between the 55th and 85th percentile (equivalent to 100% up to 175% of the award). The number of common shares that could vest over 100% of the award up to the maximum of 175% of the award, if any, will be reduced by one-half if absolute total shareholder return for the Performance Period is negative, as measured and determined by the Compensation Committee at the end of the Performance Period.

F1 · shares: The original Form 4, filed on January 3, 2024, is being amended by this Form 4 amendment to correct an administrative error of the issuer, whereupon the number of shares withheld to satisfy tax withholding obligations upon vesting of certain restricted performance shares was misreported as 5,643 shares. The corrected transaction reflects an increase of 132 shares withheld by the issuer as a result such vesting and a corresponding reduction in the number of shares beneficially owned by the reporting person.
