XBRL US Data Quality Committee Public Exposure of 14th Ruleset for US GAAP and IFRS Filers

Sponsored by Businesswire

The XBRL US Data Quality Committee (DQC) has published its 14th Ruleset for a 45-day public review and comment period, which closes on December 15, 2020. The DQC has also approved and published its 13th Ruleset; this ruleset has an effective date for filings submitted after December 31, 2020. DQC rules are freely available to US GAAP and IFRS issuers to help validate their filings and identify potential errors. Using DQC rules aids issuers to prepare consistent, error-free financials, by providing automated checks that test XBRL-formatted financial statements prior to SEC submission. The DQC is funded through the XBRL US Center for Data Quality.

Proposed Ruleset 14 contains six new rules for filers using the IFRS taxonomy with their SEC filings. These rules are similar to rules previously developed for filers using the US GAAP taxonomy. The six rules include rules that check for: missing calculations on the face financial statements, improper use of concepts between calculation trees, whether expected calculation relationships exist between primary financial statement concepts, the improper use of members with certain axes, improper scaling for percentages, and mismatch of period types for elements used with a specific axis.

Approved Ruleset 13 contains three rules for US GAAP filers, that help filers by flagging situations where a fact reported for Liability Revenue Recognized is greater than a fact reported in the same report for Contract with Customer Liability; instances where an element is used in the company’s face financial presentation but is not defined in the calculation; and situations where the Consolidation Axis is used incorrectly.

Issuers that use the freely available rules can find and correct errors, to ensure that regulators and investors are provided with good quality data and the most accurate view of corporate financial health. Filers, data providers, investors, accountants, and preparation tool providers are encouraged to review and comment on the proposed rules. Access the public review:
