Financial Statement Notes




Accurately extracting financial statement notes from financial reports is a challenging task because companies tend to use different terminologies to describe footnotes. The XBRL mandate alleviates this challenge by requiring companies to tag each footnote in its entirety using, when available, standardized TextBlock tags. For example, the most common fair value TextBlock tag is ”us-gaap:FairValueDisclosuresTextBlock” which appears across 73% of firms that report fair value (Ahn et al. 2020).


To assist researchers that are interested in textual data on financial statement notes, we provide TextBlock data. For more details on the data, please refer to the “TextBlock data dictionary.docx” and the “TextBlock Categories.xlsx” files.
