By Evan Condran. The XBRL industry continues to make strides towards improving quality of interactive data filings submitted to the SEC. On July 15, 2015, the newly formed XBRL US Center for Data Quality announced the start of its inaugural public comment period for seven proposed rules covering 2,400 elements.
The XBRL Data Quality Committee is dedicated to addressing two main areas to improve the utility of XBRL financial data filed with the SEC. The first is to provide uniform, consistent tagging of financial data and to clarify those specific circumstances where custom tags are appropriate. And the second is to automate validation rules to detect input errors and verify compliance with the Committee’s guidance.
The recently proposed rules address common XBRL input errors and consist of the following:
- Element Values Are Equal – This rule tests that the value reported for the element Assets equals the value reported for the element Liabilities and Equity.
- Context Dates After Period End Date – This rule tests that the use of dates associated with subsequent events, forecasts and the element Entity Common Stock, Shares Outstanding are appropriate.
- DEI and Block Tag Date Contexts – This rule tests that the dates used for certain Document and Entity Information, accounting policy, text block and table text block elements are consistent with the fiscal period focus of the filing (e.g., Q1, Q2, Q3 or FY).
- Element A must be less than or equal to Element B – This rule tests that the fact value for certain elements are less than or equal to the fact value of other elements.
- Negative Values – This rule tests whether the values for a given list of elements are negative. The rule does not test elements when a specified member is present which would allow the value to be negative.
- Document Period End Date Context – This rule tests that the ending date used with Document and Entity Information elements (except the elements Entity Common Stock, Shares Outstanding and Entity Public Float) matches the ending context date for the value of the Document and Entity Information element Document Period End Date.
- Document Period End Date Context / Fact Value Check – This rule tests that the ending context date for the Document Period End Date is not different by more than 3 days from the value of that element.
These rules and further documentation can be found at http://xbrl.us/home/data-quality/public-review/. We encourage Certent customers and other SEC filers to review the proposed rules and provide comments or concerns. The proposed rules are available for public exposure until September 14th, 2015.
