| Description (HTML) | Compustat’s permanent company identifier. All securities are available with an identifier, IID, which can be used along with GVKEY to permanently identify all securities tracked by Compustat, and marker items that identify the security that Compustat considers Primary.
IID Compustat’s permanent issue identifier. An identifying relationship exists between IID and GVKEY. Both must be accessed as a pair to properly identify a Compustat security. One GVKEY can have multiple IIDs. Because Compustat company data ranges can extend earlier than security ranges, there may be some time periods with no identified IID for a GVKEY. In these cases, CRSP assigns a dummy IID ending in “X” as a placeholder in the link. This range may or may not be associated with a CRSP PERMNO, but there is no Compustat security data found during the range when no IID is assigned. |
