XBRL US Data Quality Committee Public Exposure of 15th Ruleset for US GAAP and IFRS Filers

Sponsored by Businesswire

The XBRL US Data Quality Committee (DQC) has published its 15th Ruleset for a 45-day public review and comment period, which closes on June 2, 2021. This latest draft ruleset contains eight rules specific to US GAAP filers, and one new rule for IFRS filers. Since the program began in 2015, the DQC has finalized and approved 14 rulesets, covering a range of potential error types and alerting filers to possible problems in thousands of filings. The 14th ruleset was approved at the Committee’s January meeting, and has an effective date of May 1, 2021.

A subset of DQC rules has been incorporated into the US GAAP Financial Reporting Taxonomy by the Financial Accounting Standards Board (FASB), and is referenced by the Securities and Exchange Commission (SEC) in the March 2021 Electronic Data Gathering and Retrieval (EDGAR) System Filer Manual. The EDGAR Filer Manual states, “EDGAR will support new data-quality enhancing checks included by FASB in the US-GAAP 2021 taxonomy. Its DQC Rules Taxonomy (DQCRT) was developed through public review in collaboration with market participants via the XBRL US Data Quality Committee (DQC). EDGAR will inform filers of certain quality defects via warning messages.”

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, high quality XBRL 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 15 contains business rules that help issuers identify incorrect use of the business acquisition axis and the asset acquisition axis; inaccurate relationship in facts reported for gross and net acquisition; errors in the use of concentration risk; problems in summations of assets acquired net of goodwill; and issues in the consistency of facts reported over time. All error categories contain rules for US GAAP filers, and the latter category includes rules for IFRS filers as well.

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:
