Approximate Public Exposure Periods for DQC Rules and Guidance
  • April 15 – May 31
  • July 15 – August 31
  • November 15- December 31

The Data Quality Committee sought comment on Variable Interest Entities Guidance from March 16 through May 1, 2020.

Public review and comment is a critical part of the process of improving the usability of XBRL filed with the SEC. Generally, rules are considered for approval within 45 days of the close of public exposure for comment, and should be implemented in all filings within 90 days of approval.

The Data Quality Committee sought comment on six new rules and Axis-Member Tagging Guidance using the IFRS Taxonomy in version 14 of its rules during a public exposure period from November 1 through December 15, 2020.

The latest plugin releases are linked at right. See the schedule at right for approximate public exposure period timing.

Rules and Guidance Recently Exposed for Comment



Movement of Concepts between Calculation Trees (IFRS)

The rule identifies inappropriate calculation descendants of investing, financing or operating items in the company’s extension filing for the statement of cash flows. This rule identifies the calculation children of investing, financing or operating elements in the calculation linkbase of the IFRS taxonomy and compares the set of elements to the calculation children used in the company’s extension calculation linkbase. The rule creates a set of elements from the IFRS taxonomy (under each category) and compares the set to the children of the element in the extension taxonomy and flags an error if the two sets intersect.



Element Values Are Equal (IFRS)

This rule tests that the values reported between element relationships that are identified as an accounting constant are consistent within the filing. For example Assets equals Liabilities plus Equity. The rule checks that the components of the calculation are present before checking the calculation. In some cases the components may not be present but their children are. In these cases the value can be derived by adding values across a dimension.



Invalid Value for Percentage Items (IFRS)

This rule identifies where filers have used a percentage item type (as defined in the IFRS taxonomy) with a value that is greater than the value of 10.

Axis with Inappropriate Members (IFRS)

Certain axes in the IFRS taxonomy should only have certain members as shown in the IFRS taxonomy. This rule tests whether these axes have inappropriate members.

Certain axes can have custom or extended (i.e., company specific) members. This rule also tests whether only these axes have custom members and, therefore, limits the use of custom or extended members to those situations where they are appropriate because the member is unique to the filer.



FS with No Associated Calculation

The rule checks if a calculation is defined in any role of the company extension, not just the calculations associated with the roles used to define the presentation linkbase for the Income Statement, the Balance Sheet, the Statement of Cash Flows and the Statement of Comprehensive Income



Assets and Liabilities Classified as Held-For-Sale using Duration Element

This rule is intended to identify where the Assets And Liabilities Classified as Held-For-Sale axis has been used inappropriately. The rule identifies fact values with duration types that have been used with this axis. The axis is used to identify balance sheet items that are held for sale.

Guidance on Tagging Axis and Members Using the IFRS Taxonomy

Certain axes in the IFRS taxonomy should only have certain members, otherwise consumption of the data is adversely impacted because the resulting axis and member combinations are nonsensical. This guidance provides limitations on the use of certain axis and member combinations that should be adhered to when tagging financial information using the IFRS Taxonomy.
