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 · derivative.exercise_price: Each corporation restricted stock unit is the economic equivalent of one common stock.

F8 · derivative.exercise_date: The corporation restricted stock units shall vest if and to the extent that the corporation restricted stock units are earned during the performance period from January 1, 2026 through December 31, 2028, which will depend on whether the performance criteria are achieved as determined by the committee as soon as reasonably practicable, but no later than sixty (60) days following December 31, 2028, the last day of the Performance Period. The vesting of the corporation restricted stock units is subject to continued employment and accelerated vesting as provided in the applicable award agreement. The Reporting Person will receive DERs for each corporation restricted stock unit, providing for payment on the vesting date of a lump sum of cash equal to the accrued distributions from and after the grant date of the corporation restricted stock units.

F4 · derivative.expiration_date: The corporation restricted stock units and associated DERs do not expire. The corporation restricted stock units are settled upon vesting in common stocks (on a one-for-one basis) or in cash, at the discretion of the Issuer.

F9 · balance_after: This total includes corporation restricted stock units from other tranches with different vesting dates. On March 16, 2026, when the original award agreement vested, it was certified at an achievement level of 96.7% of the target number of corporation restricted stock units. The remaining 3.3% of the target corporation restricted stock units that were not earned based on the certified performance level were forfeited. The difference between the number of outstanding awards reflected in the Reporting Person's brokerage account and the number previously reported is attributable to this certification and the corresponding forfeiture of the unearned portion of the original award.
