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.

F7 · balance_after: The reporting person's immediately preceding Form 4, filed on March 3, 2026, inadvertently understated the amount of securities beneficially owned following reported transaction(s) by 920 common shares. The understatement was the net effect of two clerical errors. The first was an understatement of 20 shares in the disclosure of directly owned shares disposed of for tax withholding, resulting in an overstatement of 20 shares beneficially owned. To clarify, the Form 4 filed on March 3, 2026 should have disclosed that a total of 3,955 directly owned shares were disposed of for tax withholding (not 3,935 shares). The second clerical error was the omission of 940 directly held shares that had been previously been reported as acquired. The net of these transactions was an understatement of 920 common shares. The amount shown in this table corrects those two inadvertent clerical errors.
