The interactive quarterly timeline graphs below show changes in the total number of errors identified by the Data Quality Committee (DQC) in public company financial reports accepted into the SEC’s EDGAR database.

Check out company-specific data quality filing results.

Generally, application of the DQC’s freely-available, open-source rules and guidance has resulted in reduction of issues since the collaborative effort of industry stakeholders – filers, filing agents, data providers, academics, standard-setters and member associations – was launched in 2015. An increase in issues identified by each rule commonly corresponds to complexities associated with the annual filling period and/or subsequent revisions to the rule.
