How this page is built

Every row comes from a Form 4 filed with the SEC, which officers, directors and holders of more than 10% of a company’s stock must file within two business days of a trade. Transactions are grouped by the reporting owner’s name as filed (spacing, capitals and punctuation ignored); two different people filing under an identical name would appear together, and one person filing under two spellings appears on two pages.

Open-market totals count code P purchases and code S sales over the last 24 months. The same trade reported on more than one filing is counted once; when another owner (for example a fund and its general partner) reports the identical trade, they are listed beside it. Holdings are the shares each ownership line is left at by the person’s latest Form 4, 4/A or 5: held directly, and through each trust or entity named on the filing. A second class of common stock that converts into the listed one counts as shares; options and restricted stock units are listed but not counted. Value uses the latest trade or close, and the share of the company uses the latest shares-outstanding count the company reported. Where a filing has not yet been read line by line, the figure comes from the latest direct and indirect lines that traded and is shown as “at least”.

This page describes what was filed with the SEC; it is not investment advice or a recommendation to buy or sell any security.
