Context
The filings show option/derivative exercises or conversions and an immediate partial sale on the same day. When exercises and same-day sales occur, it is commonly to cover exercise costs or tax withholding (cashless exercise), but the filing does not state the insider’s motive. Two M entries at $0.00 indicate conversions where no cash exercise price was reported (e.g., settled/vested awards or stock-settled conversions) rather than paid purchases.
