# Insider Position Direct Indirect Total Share of Insiders Last Filed
1 Jonathan H Kaufman Director, Officer, TenPercentOwner 112,356 0 112,356 50.6% 15 May, 2024

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.
