FASB publish draft Guide to Extensible Lists
Extensible lists are a powerful XBRL feature that allow the selection of concepts from a pre-defined list.
To help filers use extensible lists efficiently and accurately, the Financial Accounting Standards Board (FASB) is creating guidance to explain the feature, its intended uses, and how to model disclosure requirements while using extensible lists. This is to support changes coming into the US GAAP taxonomy from next year.
It is important that vendors that support US SEC filers are familiar with these changes so that they can make relevant enhancements to their software.
FASB is looking for feedback on the Proposed Taxonomy Implementation Guide, Extensible Lists: A Guide for Preparers. FASB is particularly interested in whether users agree with the draft’s glossary terms and the examples used to explain when to use dimensions versus extensible lists.
Comments are welcome until 21 September, and should be submitted to xbrlguide@fasb.org.
