Definitions
In plain terms
Historical records must retain both old and new symbols and link them through the stable security or listing identity.
Technical
The event requires old and new symbols, venue, security and listing identifiers, announcement, effective and availability times, source, and corrections.
Scope
A symbol change does not by itself mean that the issuer or security was replaced.
Examples
- A governed calculation records symbol change with its exact basis, effective time, source, and units.
Common misconceptions
- Symbol Change does not have one universal treatment without the applicable methodology, event terms, and data context.
