The SEC has released a statement concerning inappropriate custom member use in XBRL pertaining to certain axes. The US GAAP reporting taxonomy has designated a limited set of permitted members for these axes. The SEC has observed that occasionally filers have inappropriately added custom members where they are not allowed.
The following are some examples of axes that only allow particular members in US GAAP:
A) Reclassification Out of Accumulated Other Comprehensive Income
A) Fair Value Recurring
B) Fair Value Non-Recurring
A) Portion at Fair Value Measurement B) Reported Value Measurement C) Estimate of Fair Value Measurement D) Changes Measurement E) Portion at Other than Fair Value Measurement
A) Subsequent Event
If these standard axes are used in SEC filings, the SEC reminds filers that they should use only allowed members where appropriate.
GoFiler follows the data quality (DQC) rules that guide member usage for particular axes for US GAAP financial filings. Contact support at firstname.lastname@example.org if you have questions about how GoFiler implements these rules.
