Rule ID: DQC.US.0241.10942
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.0241 is to ensure that filers do not use TransactionTypeAxis with market method members (OverTheCounterMember, ExchangeTradedMember, or ExchangeClearedMember). The 2026 US GAAP taxonomy introduced TransactionMarketMethodAxis specifically for disaggregating transactions by their market or clearing method. TransactionTypeAxis is intended to categorize the type of transaction (e.g., Financial Assets Sold under Agreement to Repurchase, Securities Loaned, Sale and Total Return Swap) — not the venue or method by which the transaction is executed or cleared.

Conditions:

Assertion 10942 fires when:

• A fact is tagged with TransactionTypeAxis using any of the following members:
  • OverTheCounterMember
  • ExchangeTradedMember
  • ExchangeClearedMember

Prior to the 2026 taxonomy, preparers had no dedicated axis for identifying whether a transaction was over-the-counter, exchange-traded, or exchange-cleared. Some filers applied these market method members to TransactionTypeAxis as a workaround. The 2026 taxonomy addresses this gap by introducing TransactionMarketMethodAxis, which is the correct axis for these members. Continuing to use these members on TransactionTypeAxis creates a semantic mismatch — the axis implies a transaction type distinction, but the members reflect an execution venue distinction. This misclassification can distort how data consumers interpret financial instrument disclosures.

The filer has reported a fact with the TransactionTypeAxis that is tagged with the concept FinancialAssetsSoldUnderAgreementsToRepurchaseGrossIncludingNotSubjectToMasterNettingArrangement with a value of 350000000. The TransactionTypeAxis should not be used with these transaction market method items. The filer should use the TransactionMarketMethodAxis for disaggregation of these transaction market method items.

Dimensions: TransactionTypeAxis=OverTheCounterMember

Rule Element Id: 10942 Rule version: 29.0.0RC1

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

Assertion 10942 retrieves any fact tagged with TransactionTypeAxis where the member value is one of OverTheCounterMember, ExchangeTradedMember, or ExchangeClearedMember. If any such fact is found, the assertion fires.

Filers should:

• Replace TransactionTypeAxis with TransactionMarketMethodAxis when disaggregating by over-the-counter, exchange-traded, or exchange-cleared method.
• Reserve TransactionTypeAxis for classifying the nature of the transaction itself (e.g., repurchase agreements, securities lending, total return swaps).

The TransactionMarketMethodAxis and its associated members are new in the 2026 US GAAP taxonomy.

The rule exists in the 2026 US GAAP taxonomy version.
