Rules and Guidance Recently Exposed for Comment


Axis with Inappropriate Members

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



Negative Values (IFRS only)

This rule is for filings using IFRS Taxonomies, only.
DQC 0015 Negative Values is for filings using US GAAP Taxonomies

The IFRS Taxonomy is designed so that the majority of elements have a positive value. This rule tests whether the values for a given list of elements are negative. The rule does not test elements when a specified member is present which would allow the value to be negative.


Deferred Tax Assets & Liabilities

This rule identifies where the incorrect deferred tax elements have been used between the balance sheet and the notes to the financial statements. The US GAAP taxonomy defines specific elements that should be used in the notes to the financial statements because the tax liabilities and tax assets cannot be netted across tax jurisdictions. The following table shows the correct placement of elements between the face financial statements and the notes to the financial statements.


Transition Tax Elements

This rule identifies where filers have used tax elements that are no longer applicable because of changes in the accounting standards related to taxation.


Breakdown of Operating Lease liabilities across Financial Statement Lines Items

This rule identifies 10-K, 10-K/A and 20-F filings where the filer has operating lease liabilities but has not included those operating lease liabilities in the financial statements. In these cases it is expected that the filer would indicate which financial statement line item the operating lease liability is included in.


Operating Lease Cost And Expense

This rule identifies 10-K, 10-K/A and 20-F filings where the filer has reported the operating lease expense but not the operating lease cost.


Invalid Elements Used On Range Axis

This rule identifies where filers have used either OperatingLeaseWeightedAverageRemainingLeaseTerm1 or FinanceLeaseWeightedAverageRemainingLeaseTerm1 with the Range Axis. If these elements are used with any member on the range axis then the rule will flag an error.


Incorrect Calculation of Lease Liability Payments Due

This rule identifies 10-K, 10-K/A and 20-F filings where the concept LesseeOperatingLeaseLiabilityPaymentsDue is not equal to the sum of OperatingLeaseLiability and LesseeOperatingLeaseLiabilityUndiscountedExcessAmount. The rule also identifies where the concept FinanceLeaseLiabilityPaymentsDue is not equal to the sum of FinanceLeaseLiability and FinanceLeaseLiabilityUndiscountedExcessAmount. The rule will run if either of the addends appears in the filing.
