DQC_0015-v12

Negative Values

Version 12 includes elements for public comment from the 2020 US GAAP Taxonomy. See DQC_0015_ListOfElements spreadsheet – v12 for details.

Elements that should not be reported with negative values. Documentation includes a list of elements tested.

This rule is for filings using US GAAP Taxonomies, only.
DQC 0080 Negative Values is for filings using IFRS Taxonomies


dqc_0091

Invalid Value for Percentage Items

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.


dqc_0092

IFRS-ready

IFRS Non Positive Items

This rule identifies where filers have used a positive value for an item that should be negative. The rule consists of two sub components.


dqc_0093

IFRS-ready

Durational Aggregation

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.


dqc_0094

US Maturity Schedules

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.


dqc_0095

Scale – Common Stock Outstanding

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.
