SEC filings & market structure

Delistings & Deregistrations

SEC delisting and deregistration filings: Form 25 (removal from listing on a national exchange under Rule 12d2-2 — 25-NSE is filed by the exchange itself, with the security class and the cited rule provision extracted from the structured XML) and Form 15 (the going-dark certification that terminates SEC reporting, including the 15F foreign-private-issuer variants). Form 15 coverage 1994-present; issuer-filed Form 25 from mid-2001; exchange-filed 25-NSE from 2005 Q4, when the Rule 12d2-2 amendments moved exchange filings onto EDGAR.
