Rules and Guidance Recently Exposed for Comment
This rule identifies where filers have used a percentage item type (as defined in the US GAAP taxonomy) with a value that is greater than the value of 10.
The rule identifies those elements that have a num:percentItemType data type that are base taxonomy elements. (Not extension elements) It then checks that the values reported are less than or equal to 10. If greater than 10 then an error is reported. The rule does not run on those elements which contain the text string “EffectiveIncomeTaxRate” in the concept name.
This rule identifies where filers have used a positive value for an item that should be negative. The rule consists of two sub components.
This rule identifies where the values of a durational element for a series of periods of time do not aggregate to the value representing the aggregated period in the instance.
In the 2020 taxonomy, the definition of the maturity schedule elements has changed. The changes in the 2020 taxonomy will require retagging of most subsequent quarterly filings. This rule is intended to check that the changes in the 2020 taxonomy are applied to the instance documents using this taxonomy.
The rule compares the values of the two elements and reports an error if one of the numbers is more than 100 times larger than the other number.
This DQC guidance is designed to address the introduction of the ConsolidatedEntitiesAxis in the 2020 US GAAP Taxonomy. US GAAP taxonomies up to 2019 included in the VIE section of the taxonomy a balance sheet location axis to facilitate reporting the balances on the balance sheet of the portion applicable to the VIE. This was originally designed to allow the use of the Consolidated VIE line items in conjunction with the BalanceSheetLocationAxis. Effective with the 2020 US GAAP Taxonomy, the recommended approach is to discontinue use of the BalanceSheetLocationAxis and instead use the balance sheet line items with the ConsolidatedEntitiesAxis and VariableInterestEntityPrimaryBeneficiaryMember.
