XBRL OverviewHistoryGoalsOutlookLooking DeeperExamples
HistoryStarted as AICPA projectAdopted by w3cCreation of XBRL.orgAccepted by Microsoft, SEC
GoalsCommon LanguageTo reduce filing burdensNapster for accountantsLower the cost of finance depts.
The XBRL GL was created to meet these goals:
Multi-GAAP, drill-up to multi-XBRL reporting taxonomies.
Standard format for 3rd-party software to create journal entries to pull into client GL system.
Standard format to move unposted and posted GL information back and forth from branch offices to consolidating systems, budgeting and forecasting tools, reporting tools.
Goals Cont. Standard format to upload general ledger
information as well as payables and receivables master files and open balances in migrating from one system to another or moving information to or from an Internet Application Service Provider (ASP).
Standard format to move information from client systems to CPA/CA.
Standard format to move information from one CPA/CA system (e.g., write-up) to another (e.g., tax) in an international context.
Goals Cont… Standard format to represent open receivables, open
payables, inventory balances, and other asset-based measures for sharing with banks.
Tool for representing detail drill-down for performance measurement reporting items.
Extensible for any type of mandatory audit trail. Extensible for meeting any "sub-ledger" need. Designed as XBRL spec-compliant but for easy
translation to other uses; cannot assume that XBRL period, entity, unit and other context (numeric, nonnumeric) will automatically be there.
OutlookAdoption by Microsoft, and the SEC
(Edgar Online)Adoption by 100% of major accounting
packages, Oracle, Peoplesoft, SAS…Still Immature (SEC XBRL filings are

XBRL Concept There are two components that we can consider: an XBRL instance and its associated taxonomy set. While the XBRL instance contains the concrete facts (e.g., the value of the business concept "sales_per_share") being reported, the
taxonomy contains descriptions of the business concepts (e.g., the description of the business concept "sales_per_ share", what its syntax is, how it is calculated, etc.) that are being reported.
Example XBRL
<ifrs-gp:AssetsHeldSale contextRef=“Current_AsOf”
unitRef=“U-Euros” Decimals=“0”> 100000 </ifrs-gp:AssetsHeldSale>
TaxonomiesApproved Taxonomies comply with
official guidelines for the taxonomy and with the XBRL Specification
Acknowledged Taxonomies meet the XBRL Specification only
Private Taxonomies have no requirements
Link Base – Five Links in Three Categories
Label links (labelLink) Reference links (referenceLink) Relation links (calculationLink,
definitionLink, presentationLink)
Label And Ref LinksLabel and reference links relate business concepts to metadata. For instance, label links can associate concepts with text strings that can be used to label (or otherwise document) the concept in a report
(e.g., the label "Revenues in most recent quarter" for the item revenueMRQ defined in the taxonomy). Multiple labels can be defined for a single business concept in different languages. The XBRL instance author can decide which labels to use for that particular instance.
Labels used for Authority
Similarly, reference links can associate references to authoritative literature in the business domain. The mechanism used is similar to the label links in that you define a reference link with a locator for the business concept, one or more references to documentation, and a referenceArc defining the association between the locator and the reference(s).
Links For Calculations
In contrast to label and reference links that relate business concepts to metadata, relation links relate business concepts to other business concepts. For example, calculation links define how a given concept figures in the calculation of another business concept. For example, the concept "profitAfterTax" is calculated from the concepts "profitBeforeTax" and "taxPaid" by subtracting one from the other.
profitAfterTax = weight(1) * profitBeforeTax + weight(-1)*taxPaid
More About LinksThe relationship between these three business concepts is captured in the calculationLink in Figure 3.
Definition links describe several types of relationships among business concepts, such as generalization-specialization
relationships (e.g., "postalCode" is a generalization of "zipCode") among others. Presentation links, as the name implies, define the relationships between concepts from a presentation perspective (e.g., in the presentation of the report, a parent/child relationship should be shown between "sales" and "printerSales").

Non-Audit Fees and Bond Rating – AaronCrabtreePresentation at www.bus.lsu.edu
Recent accounting scandals and perceived audit failures have resulted in excessive criticism of the accounting and auditing professions. […] Our research investigates one aspect of this situation by exploring the effects that non-audit services performed by a firm s external auditors have on perceived auditor independence in the bond market. Specifically, we analyze the effects that the magnitude and relative degree of non-audit services have on the bond rating process. Regression results indicate that the amount of non-audit services provided by a firm s external auditors is negatively associated with that client s bond rating. […] provide empirical evidence regarding the role that audit and non-audit service fees play in establishing a firm s bond rating.

Coke Misbehaves
Stephen Taub, CFO.com - January 16, 2004
The Coca-Cola Co. announced that the Securities and Exchange Commission has launched a formal investigation of the soft-drink giant.
The probe stems from allegations made by former finance manager and whistle-blower Matthew Whitley, who sought a $44.4 million settlement from the company on the grounds that he had been fired in retaliation for raising concerns about accounting fraud….
Coke Admits Misbehavior
Atlanta Journal 6/18/03
Coca-Cola admitted Tuesday that a high-level employee faked […] a written apology from Coke's president and chief operating officer.
The extraordinary exchange highlighted a day in which Coke admitted to some -- but not all -- of the allegations raised by a former employee, Matthew Whitley. […] wasn't told about the deception when Coke discovered it in 2001. Fisher was fined, but he kept his job and even was promoted. He no longer works for Coke.
The Cause ?
Coke's largest shareholder, Warren Buffett, has argued that the existence of stock options has induced many executives to doctor financial reports in order to inflate the price of company shares. Enron executives, for example, received tens of millions of dollars by cashing in stock options while their company's financial statements showed false information.
"I think accounting generally, in recent years, has deteriorated and it's done so with the help of management," said Mr. Buffett, who is a member of the boards of directors of Coca-Cola and The Washington Post.

Round Tripping
Roundtripping takes a document from its original form (e.g. XHTML) then translates it to another form (e.g. XBRL), and returns it to its original form.
Often this simple test will expose many flaws in an XBRL implementation and is a quick auditor trick to validate the XBRL generation process.

Security
"The use of vertical XML standards in financial services is on the rise. However, for XML standards such as MDDL, XBRL, RIXML to achieve widespread adoption, robust security for privacy, non-repudiation, trust and message integrity will be critical," said Mary Knox, principle analyst, Financial Services at Gartner. "Horizontal Web services standards like WS-Security, XML Encryption, XML Digital Signatures and SAML are all key enablers to the increased use of XML in financial services."
Supplementing with XML Security
XML Security Suite is a tool that provides security features such as digital signature, encryption, and access control for XML documents. These features are beyond the capability of transport-level security protocols such as Secure Sockets Layer (SSL). The goals in creating this technology were to contribute to standards development by providing sample implementations and to supply advanced technologies to partners and developers and to gather their input.

Sarbanes-Oxley Requirement
Most public companies registered with the Securities and Exchange Commission (SEC) will soon be subject to internal controls reporting similar to the requirement imposed on the large U.S. banks and other insured depository institutions more than 10 years ago. Under Section 404 of the Sarbanes-Oxley Act, most SEC registrants (other than registered investment companies) must report annually on the effectiveness of their internal controls, and their independent auditors must attest to management?s conclusions
