| # | Insider | Position | Direct | Indirect | Total | Share of Insiders | Last Filed |
|---|---|---|---|---|---|---|---|
| 1 | Hubert C Chen | Officer | 249 | 0 | 249 | 61.1% | 03 Jan, 2024 |
| 2 | Donald Allen Williams | Director | 158 | 0 | 158 | 38.9% | 02 Aug, 2023 |
Each row is that insider’s most recently reported position, from Form 4 filings over the last 60 months — which is why this total does not tie to the quarterly series above, where a quarter counts only the insiders who filed in it. Shares held through a fund or institutional portfolio are counted on the institutional ownership page instead.
