17 CFR 240.17Ad-6(a)(8)
The master securityholder file
The list of who owns the company. For each holder: legal name, address, tax identification, the positions they hold, the certificate numbers, any restrictive legend, any lock-up, and the date each of those became true.
What you see
A holder list you can pull at any date, and a page per holder showing every position they have ever held and how each one arrived.
What an examiner asks for
“Show me the file as at a date, and show me how this holder came to own this position.”
