BLOG:  Digital Financial Reporting

This is a blog for information relating to digital financial reporting.  It is for innovators and early adopters who are ushering in a new era of digital financial reporting.

Much of the information contained in this blog is summarized, condensed, better organized and articulated in my book XBRL for Dummies and in the three documents on this digital financial reporting page.

Understanding Common Logic

Consider this scenario:

Two public companies, A and B, each have some knowledge about their financial position and financial condition. They must communicate their knowledge to an investor who is making investment decisions which will make use of the combined information so as to draw some conclusions. All three parties are using a common set of basic logical principles (induction, deduction) and common financial reporting standards (i.e. US GAAP), so they should be able to communicate this information fully, so that any inferences which, say, the investor draws from public company A's input should also be derivable by public company A using basic logical principles and common financial reporting standards, and vice versa; and similarly for the investor and public company B.

This scenario has worked for about a hundred years in the US with a bit of help from regulators setting common financial reporting rules and requiring public companies to report specific information. But the parties exchanged this information using paper or "electronic paper" (HTML, PDF).

Now, think about doing this electronically/digitally and getting public company A, public company B, and the investor on the same page. Think about machines communicating and moving information between the systems of public companies, the systems of investors, and the systems of regulators.

ISO TR 9007:1987 (“Helsinki principles”) state:

  • Any meaningful exchange of utterances depends upon the prior existence of an agreed set of semantic and syntactic rules
  • The recipients of the utterances must use only these rules to interpret the received utterances, if it is to mean the same as that which was meant by the utterer

In a prior blog post I explained that Z Notation is an ISO/IEC standard for describing systems precisely. A problem with Z Notation is that it is not machine-readable.

There is another ISO/IEC standard, Common Logic, which is machine-readable. (Also see the Common Logic Wikipedia page.)

Here are some resources for understanding Common Logic:

Common Logic is about being practical.  Common logic is a compromise in order to achieve reliability, predictability, and safety.  Common logic is a "sweet spot" that achieves high expressivity but consciously gives up certain specific things that make a system unsound, so that a system will be sound. 

Common logic establishes boundaries, allowing creators of systems to "stay within the lines" and if you do, you get a more reliable, dependable system.  SQL databases are consistent with Common Logic.  SQL databases enforce constraints on data.

XBRL-based information likewise enforces constraints on information contained in, say, the financial report of a public company which is submitted to the SEC.  Just because public companies creating reports, the SEC which receives the reports, or investors using the reported information don't have to machine-readable logical rules (like I do) does not mean that the rules don't apply.  It only means that public companies, the SEC, and investors are ignorant of illogical statements being made in XBRL-based financial reports.

Don't be ignorant of information quality issues.  Use machine-readable business rules.

Wired: The End of Code

In a thought provoking article, The End of Code, Wired writer Jason Tanz explains why you will not need to understand how to code to get computers to perform useful tasks for you.  This statement pretty much summarizes the article:

Programming won’t be the sole domain of trained coders who have learned a series of arcane languages. It’ll be accessible to anyone who has ever taught a dog to roll over.

What he does not explain precisely are the pieces that will make this work.  If you have been following my blog you know what some of those pieces are.  If you want to know the others be sure to stay tuned.

If you want to catch up, please read through Knowledge Engineering Basics for Accounting Professionals.

Updated Conceptual Overview of XBRL-based, Structured, Digital Financial Report

I have updated the document 10 page Conceptual Overview of an XBRL-based, Structured, Digital Financial Report.  It is still not exactly what I want it to be, but it does now capture the full essence of what I am trying to communicate.

Even if you have read this 10 page document before, it is worth doing so again.  If anyone has ideas to improve the document even more, please send the ideas my way.

Long Standing Errors being Fixed by Public Companies

Long standing errors in the XBRL-based financial reports of public companies are being corrected.  Here is a sample of companies where a long standing error has existed but is ultimately corrected: 

Also, many filers have corrected their 10-Q filings but issues persist within the 10-K.  Typically these errors relate to conflicting information within a disclosure and within the primary financial statements.  Here are samples of filers that have issues in their 10-K, but their 10-Q is correct:

And just to round this out and to show that it is very possible to get 100% of the information within 100% of all filings correct, here are some examples of public companies that achieve this result.  I am showing income statement examples because the income statement is where most errors tend to exist.  Here are public companies that have no inconsistencies in their income statements (i.e. this is what all filings SHOULD look like):

So, it is possible to get 100% of all filings 100% correct.  There is plenty of evidence of that.

SEC Filers Decreased Errors by 64 Percent by Using Data Quality Committee Validation Rules

XBRL US: SEC Filers Decreased Errors by 64 Percent by Using Data Quality Committee Validation Rules

The rules are freely available and can be accessed on the XBRL US web site or through certain XBRL service providers. When the rules identify a potential error, they provide detailed information on the potential error with guidance on how to correct it.  In addition, an explanation of each rule’s function is available on the XBRL US website in a downloadable PDF file. Software providers can have their implementation of the rules approved by the XBRL US Center for Data Quality.
