Comments due by Tuesday, September 16, 2025:

DQC_0212

US GAAP

Missing Shares Issued or Authorized Facts When Shares Outstanding Reported

This rule ensures that when a filer reports facts for shares outstanding (such as CommonStockSharesOutstanding or SharesOutstanding), they also report the corresponding facts for shares issued and shares authorized, as appropriate. This rule validates that filings do not omit required facts that provide a complete picture of a company’s equity structure. If shares outstanding and shares issued (or authorized) are the same, both concepts should be tagged. If shares authorized are unlimited, the appropriate “unlimited” concept should be used.


DQC_0213

US GAAP

Missing Calculation Children for Key Balance Sheet Items

This rule ensures that key balance sheet concepts, such as Assets, AssetsCurrent, NoncurrentAssets, Liabilities, LiabilitiesCurrent, LiabilitiesNoncurrent, and StockholdersEquity are not reported as leaf items (i.e., without calculation children) in the balance sheet calculation linkbase.


DQC_0214

US GAAP

Missing Equity Concepts in Balance Sheet Calculation

This rule ensures that key equity related facts disclosed in the financial statements, such as Treasury Stock, Common Stock, Additional Paid-In Capital, Retained Earnings, Accumulated Other Comprehensive Income (Loss), Noncontrolling Interest, and Preferred Stock—are also included in the equity section of the balance sheet calculation relationships.


DQC_0215

US GAAP

Extension Element Name Matches US GAAP Element

This rule ensures that when a filer reports an extensible enumeration fact value indicating the location of a face statement concept, the corresponding monetary fact value for that concept is also reported in the filing.


DQC_0216

US GAAP

Improper Use of Extension Geography Members on StatementGeographicalAxis

This rule ensures that filers use the appropriate standard members for the StatementGeographicalAxis, specifically when only two members are present: one representing the United States and one representing non-US regions.


DQC_0217

US GAAP

Improper Use of Notional Amount Concepts with InvestmentIdentifierAxis

This rule ensures that notional amount concepts, specifically DerivativeLiabilityNotionalAmount and DerivativeAssetNotionalAmount, are not reported with the InvestmentIdentifierAxis. This rule enforces correct dimensional tagging for derivative notional amounts, in accordance with SEC guidance, to promote accurate, complete, and consistent reporting in the Schedule of Investments (SOI).


DQC_0219

US GAAP

Missing Value for NonInvestmentAssets LessNonInvestmentLiabilities

This rule ensures that filers report a value for the element NonInvestmentAssetsLessNonInvestmentLiabilities when certain conditions are met in the filing. Specifically, if the filer has reported both AssetsNet and InvestmentOwnedAtFairValue in the same context, and AssetsNet has a calculation child of InvestmentOwnedAtFairValue as well as an extension item with a negative value, then the filer should also report a value for NonInvestmentAssetsLessNonInvestmentLiabilities.


DQC_0220

US GAAP

Improper Use of StatementTable in Notes Disclosures

This rule ensures that filers do not use the StatementTable element in the notes disclosures section of their filings. The StatementTable is intended to be used only in the face financial statements, not in the notes.


DQC_0221

US GAAP

Missing NumberOfReportableSegments When Segment Facts Are Reported

This rule ensures that filers report the NumberOfReportableSegments element whenever segment facts are disclosed in the filing. Even if a filer only has one segment, the number of reportable segments must be explicitly reported.


DQC_0222

US GAAP

Scaling Error in EntityPublicFloat

This rule ensures the value reported for `dei:EntityPublicFloat` is correctly scaled and falls within a reasonable range for both standard and small business filers.


DQC_0223

IFRS

Extension Leaf Items on Statement of Operating Activities or Income Statement

This rule ensures extension concepts used as leaf items (i.e., items with no calculation children) on the statement of operating activities or income statement are appropriately named.
