Public review and comment is a critical part of the process of improving the usability of XBRL filed with the SEC. Generally, rules are considered for approval within 45 days of the close of public exposure for comment, and should be implemented in all filings within 90 days of approval.

In the current Public Review period – version 20 – the Data Quality Committee seeks comment on seven new automated checks, as well as updates to rules for filers using the US GAAP and IFRS taxonomies, from November 15 through Saturday, December 31, 2022.

Comments due by Saturday, December 31, 2022:



Typed Dimension Axis Restriction

This rule checks that the new typed dimensions to support Business Development Corporation (BDC) filings are defined correctly. The rule checks that each fact is associated with 1 typed dimension. Each fact should using a typed investment dimension, cannot use another explicit dimension. The only exception to the rule is the use of the explicit axis InvestmentCompanyNonconsolidatedSubsidiaryAxis, which was added as part of the BDC taxonomy upgrade.



Derivative Position Extensible Enumeration

This rule checks that the extensible enumeration element DerivativePositionExtensibleEnumeration can only use two values. The two allows values are:

  • CallOptionMember
  • PutOptionMember



No Balance Attribute in Financial Statements

This rule checks that extension monetary elements included in the balance sheet, income statement, cash flow statements and shareholders equity statements include a balance attribute. This is important so that data users have some idea what type of element the extension element is. If it is in the balance sheet then a credit is a liability or equity and if it is a debit then it is clear it is some kind of asset, thus allowing reasonable classification.



Inappropriate Cash Flow Presentation

This rule looks at the presentation linkbase of the cash flow statement and income statement to determine that elements have been presented correctly. The rule has three parts.



Incorrect Period Reported

This rule identifies incorrect period durations used in the income statement of the 10-K. The rule identifies where a company has reported a 10K but the majority of the values reported on the Income Statement are for a period other than a year. Although uncommon, this rule is provided to allow filers to detect if this situation has occurred.



Incorrect Sign of Elimination Items

This rule identifies when a filer enters a positive value for an element using the elimination member (on the consolidated items access) when it should be negative. The rule uses the same logic as used for the non negative rule (DQC_0015)



OCI Items In Income

This rule identifies if OCI items have been included in the calculation of net income.
