1. Inline XBRL vs. XBRL forFinancial ReportingUWCISASymposium on Information Integrity & IS Assurance- Toronto, Oct 3, 2013 - Clinton E. White, Jr (Skip) Lerner College of B&E University of Delaware skipw@udel.edu

2. iXBRL vs. XBRL • When you open an income statement with your browser, which would you prefer to see?

3. XBRLan XML vocabulary • XBRL • XBRL is an XML vocabulary for business operations and financial reporting • XML – the Extensible Markup Language • A set of rules & syntax for encoding documents in a format that is both computer and human-readable • Simplicity … generality … usable over a network • The default way to encode documents for software-to-software exchanges over networks and between applications (e.g., office productivity tools)

4. XBRLthe original concept • XBRL • Crate an XML vocabulary with which to encode financial information so that it is software-readable and can be exchanged and unambiguously interpreted and used by software or humans • Without being bound to a presentation format

5. XBRLas implemented by the SEC • Document format files: • HTML format (including financials) • Official filings • Audited or reviewed • Data files: • Financials in XBRL format • Supplemental filings • Not audited or reviewed • Separate but presumed to be equal

6. XBRL at the SEC

7. XBRL at the SEC • Data files: • Each line item & disclosure tagged with a tag from the US GAAP taxonomy or the company’s extension taxonomy • <us-gaap:SalesRevenueNetcontextRef="FROM_Jan01_2012_TO_Dec31_2012" unitRef="USD“ decimals="-3" > 29904000000 </us-gaap:SalesRevenueNet> US GAAP: http://xbrl.us/taxonomies/Pages/US-GAAP2013.aspx

8. XBRL at the SEC • Document files: • HTML (presentation) format

9. Document & Data Files • Why are companies required to file both document and data files? • Document files • The “original,” “official” file(s) • Audited (or reviewed), legal document(s) • Data files • The computer-processable file(s) • Unaudited, reusable data, validateable

10. XBRL at the SEChybrid documents • Each line item & disclosure tagged with a tag from the US GAAP taxonomy or the company’s extension taxonomy • Each disclosure tagged and its contents formatted with HTML multiple times to appear exactly as it does on paper (Levels 1, 2, & 3 tagging) • Difficult to process and analyze • Difficult to compare to the official HTML documents • Hybrid XBRL instance documents

11. Inline XBRL • What if we embedded the XBRL formatted financial statement in a HTML document so that it renders in humanly-readable format – exactly as in paper form? • And, we can extract an XBRL instance document when needed!

12. iXBRL • Inline XBRL 1.1 • Working draft: March 2013 • For embedding XBRL fragments into an HTML document (XBRL International) • When processed by an XML processor, it is rendered as a Web page instead of an XBRL document XBRL.org: http://www.xbrl.org/news/xbrl-international-seeks-feedback-inline-xbrl-11

13. 3M Consolidated Income Statement(XBRL instance - 10-K 12/31/2012)

14. 3M Consolidated Income Statement(iXBRL)

15. iXBRL • iXBRL documents: • The “source” document is the “official” document • An XML document with an HTML root element • Actually, XHTML document • Contains the XBRL tagged items formatted and in exactly the same order as when rendered • Renders exactly as intended by the entity • The XBRL instance document is extractable from the “source” document • Referred to as a “target” document • It is usable by XBRL analysis software & is valedatable

16. iXBRL • One “source” document • The XBRL is more transparent and easier to process for analysis purposes • Much easier to provide assurance that the XBRL is complete, consistent, & mapped & structured correctly • Much more user-friendly • No redundancy in disclosures

17. 3M Co’sNet sales revenue- iXBRL - <ix:nonFraction name="us-gaap:SalesRevenueNet" contextRef="FROM_Jan01_2012_TO_Dec31_2012" unitRef="USD" decimals="-3" format="ixt:numcommadot" id="ID-15" scale="3"> 29,904 </ix:nonFraction>

18. iXBRL • Can take advantage of HTML5 & CSS3 • A semantic HTML • Incorporates much of XHTML • Includes new APIs for dynamic Web pages • CSS3: • Supports namespaces • More powerful styling features • Reusable, maintainable code
