Names are printed the way the filer wrote them on the form. The SEC does not keep separate first and last names for reporting owners. It keeps one string, and filers usually put an individual's surname first. That is why this reads as a surname directory, and why a chief executive you know as Jane Adams is filed under A.
Not everyone listed is a person. Anyone holding more than 10% of a class of shares reports on Form 4 just as an executive does, so funds, holding companies, family trusts and employee stock plans appear next to individuals. Their buying is a portfolio decision, not a view from inside the business. Keep that in mind before reading much into a large institutional purchase.
Everyone we hold a page for is listed, however long ago they last filed. An insider whose last Form 4 was three years ago sits here next to one who filed this morning, because their history is still worth reading.
