Disclosure Analysis Prototype

Charlie in Becoming an XBRL Master Craftsman

I created a disclosure analysis prototype.  This analysis tool prototype looks at the current inventory components roll up.  It compares the Level 3 Disclosure Text Block representation and the Level 4 Disclosure Detail representation.  You can see and compare the text block and the detail side-by-side.

The rules for the disclosure are useful not only for verifying that disclosures were created correctly, but also for querying information from reports.  I realize this prototype needs more work to make it more useful, I am just trying to get all the basic pieces of the puzzle working.

Currently, the working prototype has information for the S&P 500 companies from their 2016 form 10-K.  All of the information and renderings are provided to me by the XBRL Cloud Edgar Report Information Web Service API.  With permission, I created copies of the renderings, stripped out the detail that you can normally drill down to (you have to subscribe to XBRL Cloud to get that functionality), and use that information to provide the comparisons.

Additionally, you can navigate to the publicly available XBRL Cloud viewer to look at details.  I also link you to the SEC Filing Page of the XBRL-based financial report submission so you can go look at that.

Here are some observations that I have. Of the 500 companies analyzed:

What about the other 75?  Well, I am figuring that out.

Here are some specific observations:

Anyway, I will leave it at that for the time being.  Interesting stuff.  This would be a great resource for teaching intermediate accounting.

If you have any ideas that would help turn this into a useful tool, be sure to send them my way.
