Firm Complexity and Accounting Reporting Complexity
Level 4 tagging enables research using the monetary value in each XBRL tag or the information about each tag (metadata). In a recent Accounting Review article (Hoitash and Hoitash 2018) we propose a new measure of accounting reporting complexity (ARC) constructed based on the count of accounting items (XBRL tags) disclosed in XBRL filings. The ARC data and several related measures are updated twice a year and can be downloaded in an Excel or SAS format from the accounting reporting complexity page.
Financial Statement Notes
Level 1 tagging enables an accurate extraction and classification of financial statement notes, a task that is otherwise hard to accomplish . In a recent article, forthcoming in The Accounting Review (Ahn, Hoitash, and Hoitash) we extract and examine the fair value footnote. Data on many prevalent footnotes, including the complete text and count of words is available for download in text and SAS format from the financial statement notes page.
