Rule ID: DQC.US.0235.10931, DQC.US.0235.10932
Public Exposure May 6 - June 20, 2026 - provide comment at https://xbrl.us/public-review
Effective date: TBD

Purpose:

The purpose of Rule DQC.US.0235 is to ensure that filers do not use the CollateralAxis with gross repurchase agreement and securities loaned concepts. These concepts represent gross obligations that should be disaggregated by class of collateral pledged using CollateralPledgedInSecuredBorrowingAxis, not CollateralAxis. Using the wrong axis creates ambiguity about the nature of the collateral breakdown and is inconsistent with the taxonomy's intended hierarchy for secured borrowing disclosures.

Conditions:

Both assertions (10931 and 10932) flag any fact for either of the following concepts when tagged with any member on CollateralAxis:

• FinancialAssetsSoldUnderAgreementsToRepurchaseGrossIncludingNotSubjectToMasterNettingArrangement
• SecuritiesLoanedIncludingNotSubjectToMasterNettingArrangementAndAssetsOtherThanSecuritiesTransferred

The rule applies regardless of the member value used on CollateralAxis.

Repurchase agreements and securities lending transactions require detailed disclosures about the collateral pledged to secure the obligations. The US GAAP taxonomy provides CollateralPledgedInSecuredBorrowingAxis specifically for disaggregating gross secured borrowing obligations by the class of collateral involved. Using the more generic CollateralAxis with these concepts does not convey the full picture of the collateral type supporting the secured borrowing, which can mislead financial data consumers and analysts seeking to understand repo and securities lending exposure by collateral class.

The filer has reported a fact value for the concept FinancialAssetsSoldUnderAgreementsToRepurchaseGrossIncludingNotSubjectToMasterNettingArrangement of 250000000 with the CollateralAxis. This axis should not be used with this concept. The CollateralPledgedInSecuredBorrowingAxis should be used for disaggregation of the gross obligation by class of collateral pledged.

Rule Element Id: 10931
Rule version: 29.0.0RC1

The rule element ID is used to identify unique elements or combinations of elements tested in the rule.

Both assertions (10931, 10932) retrieve any fact for the two monitored concepts (FinancialAssetsSoldUnderAgreementsToRepurchaseGrossIncludingNotSubjectToMasterNettingArrangement and SecuritiesLoanedIncludingNotSubjectToMasterNettingArrangementAndAssetsOtherThanSecuritiesTransferred) that carry any member on CollateralAxis. If such a fact exists, the assertion evaluates as true (error).

Filers should replace CollateralAxis with CollateralPledgedInSecuredBorrowingAxis when disaggregating these gross secured borrowing obligation concepts by collateral class.

The rule exists in the 2026 US GAAP taxonomy version.
