Eleven new rules and one updated rule for US GAAP and IFRS taxonomy filers were available for public comment from November 15 through December 31, 2023. Members of the Data Quality Committee Approved these rules by email on January 16, 2024.

On March 14, the effective date of filings for this version was amended by the Committee to be filings submitted after May 15, 2024.

Effective with Version 23.0.5, the minimum required XULE version for using these rules is 23722.

New Rules:

  • DQC_0152 – Year List Items Used with Tax Period Axis - This rule identifies where the filer has used a concept with a data-type of YearListItemType with the axis TaxPeriodAxis. When using an element with this datatype all tax years should be included in a list in a single context. This datatype eliminates the need to break out the tax years using a dimension. The rule identifies every fact that uses a concept with this data-type and the TaxPeriodAxis.
  • DQC_0166 – Facts without Hypercubes - This rule identifies where the filer has created facts with dimensions that do not fit into a hypercube defined in the extension taxonomy.
  • DQC_0167 – Inconsistent Calculation Roots - The rule is intended to detect those filings where filers have not defined the calculation linkbase correctly for the Balance Sheet, Income Statement and Statement of Comprehensive Income.
  • DQC_0168 – Tax Reconciliation Calculation - This rule identifies where the filer has not reported a calculation linkbase for the monetary and rate based tax reconciliation in a 10-K or 20-F filing.
  • DQC_0169 – Calculation in the Parenthetical Disclosure - This rule identifies where the filer has defined a calculation in the parenthetical disclosure network of a Statement.
  • DQC_0170 – ECD Rule 10b51 Flag Disclosures - This rule identifies where the filer has not reported the ECD Rule 10b51 Flag Disclosures that should be reported with a value of false if they had no such disclosures to make. The rule identifies if this flag is not reported in 10-K and 20-F filings with a document period end date after 2023-12-31. The rule checks if the following 4 flags defined in the ECD taxonomy are missing:
    • Rule10b51ArrAdoptedFlag,
    • NonRule10b51ArrAdoptedFlag,
    • Rule10b51ArrTrmntdFlag,
    • NonRule10b51ArrTrmntdFlag
      The SEC ECD taxonomy requires that these 4 flags are tagged even if the values are false.
  • DQC_0171 – ASU 201613 Transition Elements - This rule identifies where the filer has reported ASU 201613 Transition elements in the filing. The rule will flag fact values with an end date greater than 2023-09-30 using one of these elements. Exceptions include:
    • FinancingReceivableAllowanceForCreditLossesIndividuallyEvaluatedForImpairment1,
    • FinancingReceivableAllowanceForCreditLossesCollectivelyEvaluatedForImpairment,
    • ImpairedFinancingReceivableAverageRecordedInvestment,
    • ImpairedFinancingReceivableWithNoRelatedAllowanceAverageRecordedInvestment,
    • HeldToMaturitySecuritiesInUnrealizedLossPositionsQualitativeDisclosureNumberOfPositions
  • DQC_0172 – Reporting Right of use Assets - The rule detects where filers have reported RightofuseAssets but not included it on the Statements and have used the element PropertyPlantAndEquipment instead of the correct element PropertyPlantAndEquipmentIncludingRightofuseAssets.
  • DQC_0173 – IFRS Transition Elements - This rule identifies concepts in the IFRS taxonomy that are being transitioned and that should not be used in filings after 2023-01-01.
  • DQC_0175 – Litigation Settlement Roll Forward Elements - This rule identifies where the LitigationSettlementAmountAwardedFromOtherParty or LitigationSettlementAmountAwardedToOtherParty concepts role up into an income statement account.
  • DQC_0176 – US-GAAP Elements used in IFRS Filings - This rule identifies where filers have reported a US-GAAP element in an IFRS filing.
  • DQC_0177 – Addition of PEO and Nonpeo Compensation Adjustments - This rule applies to proxy disclosures. This rule identifies where filers have reported an adjustment compensation amount that does not tie to the difference between the total compensation amount (PeoTotalCompAmt, NonPeoNeoAvgTotalCompAmt) and the actual compensation amount paid (PeoActuallyPaidCompAmt, NonPeoNeoAvgCompActuallyPaidAmt).

About the DQC Rules Plugin

The DQC ruleset .zip files are compiled checks written in an XBRL rule syntax called XULE. The checks are invoked using an Arelle plugin on a local computer or server. After Arelle processes an XBRL instance, a taxonomy or an extension taxonomy, the DQC plugin determines the proper compiled assertions to use (ruleset) and returns validation messages to note issues.
