DEI FactsLast Updated: 11/12/18
DEI Fact Basics
DEI includes facts about your organization, filing documents, filing period, and other information that is required for filing.
When tagging DEI:
For traditional XBRL, tag the DEI facts in a table in a non-printing section of the document.
For iXBRL, tag as much as possible on the cover page, including DEI facts such as form type, period end date, and company name. Tag the rest of the DEI facts in a table in a non-printing section of the document.
DEI Fact Use for Common Forms
Use the following table as a guide for which DEI facts to include in various filing forms.
To make sure you enter DEI values correctly, view the XBRL concept details. The correct format for a fact value is often in the documentation for concepts contained in the DEI. You can find additional details related to each concept in the Taxonomy Analyzer.
NOTE: For 8-K and 6-K filings, use this information only when your filing requires XBRL (refer to Interactive Data to Improve Financial Reporting to determine if your filing needs XBRL).
Elements included in the table are based on the following rules in the EDGAR Filer Manual: 6.5.20, 6.5.21, 6.5.26, and 6.5.40.
AmendmentDescription is only required if the value for AmendmentFlag is “true”.
A 10-K should have a fiscal period focus of “FY”.
These elements correspond to elements that may be disclosed on an Entity’s cover. If the element is disclosed on the cover page or a validation message is triggered, add the appropriate concept and determine if the fact value should be “true” or “false”.
These elements were created in the 2018 taxonomy. If you are in the 2017 taxonomy and see validation messages related to these items, they can be ignored and will not prevent you from filing. Once you have migrated to the 2018 taxonomy you will need to add the appropriate elements.
