Is this Glenn P Muir’s net worth? No. A Form 4 reports the shares an insider owns in one company after each transaction, directly or through trusts and entities. It says nothing about cash, other investments, property or debt, options not yet exercised are not counted here, and a holding reported some time ago may have changed without a new filing. The value is shares times the last stored close, not a price anyone received. Sources: the filings listed below, each linked to EDGAR. Compare with the biggest insider stakes.
