XBRL US Data Quality Committee Public Exposure of 12th Ruleset

Sponsored by Businesswire

The XBRL US Data Quality Committee (DQC) has published its 12th Ruleset for a 45-day public review and comment period, which closes on June 1, 2020. DQC rules aid US GAAP and IFRS issuers in preparing consistent, error-free financials, by providing automated checks that test an XBRL-formatted financial statement prior to SEC submission. Issuers that use the 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. Access the public review:

The latest Ruleset contains three new rules for US GAAP filers which alert filers to situations where: 1) an invalid value was reported for a percentage item; 2) values on Maturity Schedules were not tagged correctly; and 3) scale is not correct for values reported for common stock outstanding. The Ruleset also augments the existing US GAAP Negative Value rule with additional concepts to help filers guard against signage problems.

Ruleset 12 also contains two new rules for IFRS filers which identify: 1) values that were reported as positive but should be negative, and 2) values reported for durational elements that do not aggregate correctly.

Separately, the Data Quality Committee is also seeking comment on guidance prepared to help in XBRL formatting for Variable Interest Entities. This guidance is out for public review until May 1, 2020. Access this guidance:
