Create extension concepts

Sometimes standard taxonomy concepts do not fit a value in your report. To tag the value accurately, you need to create a custom (or extension) concept, which are unique to your company.

Basics of extension concepts

Extension concepts have the same attributes as standard concepts:

• Label is the standard name for the concept, such as Deferred Tax Asset, Interest Carryforward.
• Type is the type of concept. It can be non-numeric (abstracts, members, text blocks, etc.) or numeric (monetary, shares, percent, etc.).
• Documentation is additional information about the concept, which appears in viewers, such as the SEC Viewer.
• Data Type is the kind of data you are tagging, such as Date Item Type, Monetary Item Type, Text Block Item Type, etc.
• Balance Type is for monetary concepts, select Credit or Debit. Otherwise, select Unspecified. When creating a concept like Gain (Loss) to represent both positive and negative values, select the balance type associated with the positive value.
• Period Type is for numeric concepts, specify Instant or Duration.
• Abstract is for a concept you use to organize or group other concepts within the XBRL outline Presentation section, such as Income Statement [Abstract]. Do not use it for a fact or data.
