The rules in this release pertain mainly to the US GAAP taxonomy and are as follows:

DQC_0015-V15 (Negative Values (US GAAP))

Version 15 includes 187 elements for public comment from the 2021 US GAAP Taxonomy. See DQC_0015_ListOfElements spreadsheet – v15 for details. These elements should not be reported with negative values. The documentation includes a list of elements tested. This rule is for filings using US GAAP Taxonomies, only. See DQC 0080 Negative Values for filings using IFRS Taxonomies

DQC_0107 (General Text Block (US GAAP))

The rule identifies where the text block “Schedule Of Acquired Finite Lived Intangible Assets By Major Class Text Block” is used with a value on the Business Acquisition Axis.

DQC_0108 (Fact Value Consistency Over Time (US GAAP))

The rule identifies those facts that are only expected to grow over a reporting period. This rule is intended to identify those cases where the value of a monetary fact has a larger value reported than the value reported for another fact that represents the same concept but over a longer duration of time. The rule also identifies any elements that cannot be negative but may increase or decrease over a measurement period. The rule excludes the following elements that meet this category: CapitalExpendituresIncurredButNotYetPaid and ConstructionInProgressExpendituresIncurredButNotYetPaid.

DQC_0109 (Concentration Risk (US GAAP))

This rule consists of several parts that check concentration risks are reported correctly. All of the parts use the line item ConcentrationRiskPercentage1. The correct reporting of concentration risk requires use of multiple dimensions. The Concentration Risk by Benchmark Axis and Concentration Risk by Type Axis are required for all disclosures. A third axis (e.g., Major Customers Axis or Statement Geographical Axis) may be used to disaggregate the data.

DQC_0110 (Missing Business Acquisition Axis (Short Period) (US GAAP))

This rule identifies where the company has reported the details of a specific acquisition but has not identified the actual acquisition. It also identifies those cases where the aggregate consideration transferred for the reporting period has not been reported using appropriate dates. This rule will flag errors for those cases where the company has not used the Business Acquisition Axis. The rule concerns those cases where the element BusinessCombinationConsiderationTransferred1 has been used with no dimensions but has been reported with a duration period less than the reporting period by 20 days.

DQC_0112 (Line Items Requiring the Business Acquisition Axis (US GAAP))

This rule is intended to identify those cases where facts are expected to include the business acquisition axis. The rule checks a list of line item concepts are reported with the business acquisition axis and a member representing the actual acquisition.

DQC_0113 (Gross Acquisition Less Than Net Acquisition (US GAAP))

This rule ensures that filers use the correct elements to identify the Gross Payments and the Net Payments for business acquisitions. This rule is intended to identify those cases where the company reports the total “Payments To Acquire Businesses Gross” with an amount that is less than the value of “Payments To Acquire Businesses Net Of Cash Acquired”.

DQC_0114 (Assets Acquired Net of Goodwill (US GAAP))

This rule is intended to identify those cases where the company reports the values of assets acquired and liabilities assumed excluding goodwill, the value of assets acquired and liabilities assumed including goodwill and the value of goodwill. The rule flags an error when the value net of goodwill plus goodwill does not equal the amount including goodwill. This rule only concerns those facts that use the BusinessAcquisitionAxis.

DQC_0115 (Fact Value Consistency Over Time (IFRS))

This rule ensures that filers consistently use the same element across durations of time. This rule flags an error where the value of a monetary fact has a larger value reported than the value reported for another fact that represents the same concept, but over a longer duration of time. This is based on the list of items that cannot be negative. Of these, the rule identifies only concepts that are monetary and have a period of a duration.

DQC_0116 (Line Items Requiring the Asset Acquisition Axis (US GAAP))

This rule identifies those cases where the company reports facts that are expected to include the Asset Acquisition Axis. An error will occur when specific line-item concepts are reported without the Asset Acquisition Axis and a member representing the actual acquisition.
