Typed Dimension Axis Restriction

Rule ID: DQC_0142
Status: Final
Release date: January 25, 2023
Effective date: March 31, 2023

Rule function

This rule is intended to identify those cases where a Business Development Corporation (BDC) used more than one dimension on a fact to identify the details of a security position. BDC reporting requires that companies list the individual investments in an investment schedule. To report each individual investment a typed dimension must be used by the filer. The values on the specific line of the investment schedule must be tagged with the same typed dimension member and only that dimension member. No additional axis should be associated with a fact that represents the details of an investment position, such as the interest rate or face value.

The rule identifies those facts where the filer has associated the fact with one of the following axis:

  • InvestmentIdentifierAxis
  • SecuritySoldShortIdentifierAxis
  • OpenOptionContractIdentifierAxis
  • OpenFuturesContractIdentifierAxis
  • OpenForwardForeignCurrencyContractIdentifierAxis
  • OpenSwapContractIdentifierAxis

The rule then checks if the fact only has one axis. If the fact has more than one axis then the rule flags an error.

There is one exceptional case where two dimensions can be associated with the fact. That case is when the filer also includes the axis InvestmentCompanyNonconsolidatedSubsidiaryAxis. This axis is used when the filer reports the investments for a non consolidated subsidiary.

Problem solved by the rule

The rule is intended to ensure consistency of BDC filings. The investment schedule could be tagged with multiple dimensions depending on the presentation. This rule ensures that investment disclosures are consistent across filers irrespective of the presentation used.

Example rule message

The filing reports a value of 1,200,000 for the concept BondFaceValue using the InvestmentIdentifierAxis.

If the InvestmentIdentifierAxis is used no other axis should be used. Remove any additional axis on this fact.
