Registration by Coordination
As the name implies, registration by coordination is used to coordinate the state and federal filings of a securities issue. In other words, it is used primarily by companies that are registering their securities for the first time with the SEC and want to register their securities with certain states at the same time. This most commonly occurs with larger issuers who would like their securities to be made available to investors in multiple states.
The most important step is filing the appropriate registration statement at the federal level, before trying to register securities at the state level. All state level registrations under a registration by coordination happen after the federal registration and reuse much of that paperwork. Note that securities that are registered federally are not the same as federally covered securities, although many securities fall into both categories
