“The Securities and Exchange Commission is clamping down on public companies that fail to submit their financial disclosure statements as structured data, agency officials said. The SEC’s Division of Corporation Finance sent letters on July 7 to an unspecified number of companies that are not submitting their financial disclosure statements as machine-readable, structured data. The move comes in the wake of continuing pressure on the SEC by lawmakers, academics, and open data advocacy groups to enforce an agency requirement that has been in place since 2009 for large-sized businesses and gradually phased in over a four-year period for midsized and smaller companies. The target format is XBRL (eXtensible Business Reporting Language), a language for documenting financial reports in XML. A sample letter posted on the SEC’s website indicates that the agency is reminding non-complying companies that its rules require that they file an XBRL version of their quarterly financials and that they include calculation relationships for certain contributing line elements of their financials and related footnotes.”
