Source: SEC Form 4 filings, via EDGAR. A derivative line reports the shares underlying an option rather than stock outstanding, so it is marked and is not comparable with the rest. Value is shares times the reported price, and is blank where the filing priced the transaction at zero — a grant costs its recipient nothing. Insiders sell for reasons that have nothing to do with the company, which is why a sale is not read as a signal on its own.
