With compliance dates approaching, reviewing the SEC’s mandate for operating companies and funds that they report their financial information in Inline XBRL (iXBRL) is important. These requirements date back to June 2018, when the SEC passed rules seeking to modernize and simplify financial reporting for these filers. Unlike traditional XBRL which produces a XML document containing only tagged, structured data that is difficult for a human reader to understand and interpret, iXBRL involves embedding XBRL data directly into an HTML filing so that the disclosure document is both human-readable as a formatted report of financial information and machine-readable since the tagged data can be collected and used in subsequent analyses in any number of ways. Using iXBRL improves the data’s usefulness, timeliness, and quality, which benefits investors, regulators, market participants, and other data consumers. Inline XBRL also reduces burdens and complexity to registrants and preparers as only one document containing both the formatted report and the structured data must be produced.
