1. ACG 5405 Introduction to XBRL

2. Networked What does it mean to be networked? –It means the ability to pass data between software applications across a network –It requires standardized communication protocols –It requires an agreement between the sending & receiving applications

3. Connectivity What is the primary problem with networking/connectivity? –Software applications that do not understand each other … therefore special interfaces must be designed & maintained, etc. –And humans have different understandings and views of data and information produced by the applications

4. Electronic Business Electronically exchanging information and linking business processes, individuals and organizations Transactions completed more quickly, more efficiently, and more effectively Eliminates paper trail (eventually)

5. Electronic Data Interchange (EDI) Computer-Computer Business Data Direct processing Standardized –ANSI X12ANSI X12 US and Canada –EDIFACT International

8. XBRL: What is it? XBRL (Extensible Business Reporting Language) is a royalty-free, open specification for software that uses XML data tags to describe financial information for public and private companies and other organizations. XBRL benefits all members of the financial information supply chain by utilizing a standards-based method with which users can prepare, publish in a variety of formats, exchange and analyze financial statements and the information they contain. The world's leading accounting, financial, government and software organizations are involved in the adoption and use of XBRL in the U.S.

9. What was accounting like before XBRL? Accounting Cycle –Journal, Ledger, Trial Balance, Financial Statements –Debits and Credits Text based! Manual input, manual interpretation, Re- entry of data for each separate use

10. XBRL X –eXtensible B –Business R –Reporting L –Language Vocabulary based on XML –Extensible Markup Language –Rules for describing data

11. Who is behind XBRL Securities Exchange Commission –Public filings are currently voluntarily filed in XBRL format –Mandatory public filings coming soon... –Interactive Data! AICPA –Efficiencies to the accounting profession –Re-use of data without manual re-entering XBRL International –Non-profit Organization –Creates Standards XBRL U.S. –Charged with creating US GAAP taxonomy

12. XBRL Milestones April 1998 –XBRL is conceived by Charles Hoffman, a CPA with the firm Knight Vale and Gregory in Tacoma, Washington October 1999 –AICPA hosts first meeting July 2000 –Spec 1.0 is released and International organization created February 2005 –SEC creates voluntary program for reporting XBRL financial data on EDGAR September 25th 2006 –SEC’s chairman Christopher Cox announces contracts totaling $54 million... To Modernize and Maintain the EDGAR Database to Use Interactive Data Complete XBRL Code Writing for U.S. GAAP Financial Statements Create Interactive Data Tools for Investors September 2006 –XBRL US, the United States jurisdiction of XBRL International, spins off from the XBRL committee of the AICPA. September 25th 2007 –SEC’s chairman Christopher Cox announces the completion of all development work on data tags for financial reporting in accordance with U.S. generally accepted accounting principles October 9th 2007 –SEC’s chairman Christopher Cox announces the creation of a new office within the 74-year old agency to lead the transformation to interactive financial reporting by public companies –... the new office is the agency-wide disclosure modernization program

13. XML in Business What if you need to move information from one business application to another within your organization? What if you have data in a number of different databases that you frequently need to integrate, compare, share internally? What if you need to share information with trading partners & others outside your organization? XML provides the necessary rules, syntax & structure to make it possible!

14. XML How can you appropriately structure information exchanges so that they can be seamless & efficient? –There are 2 parts to the solution: –1) Metadata – adding data about the data … data that gives the data more meaning –2) Agreement on structure of the data being shared … an agreed upon vocabulary defining the rules the metadata must follow In addition, the solution must be general enough to be able to be applied universally!

15. XML Extensible Markup Language Markup? –Data being exchanged Sent from computer-to-computer (intra and inter- organizationally) –Defining the data Enclosing the data with descriptions of what the data is –<> Tags used to enclose data Used to create Vocabularies –Standardized sets of tags (kind of like EDI) –XBRL is one such vocabulary

16. XML Concepts Prolog –the first line of any XML based document – Element –A Tag set (the tag name, its attribute and data) –Root Element Contains (or encloses) all the other elements – Parent Element Contains other elements –Child Element Enclosed by Parent element Attributes –used to modify or clarify the data in an element 130

17. Element Hierarchy <tourGuide> <city> <cityName>Belmopan</cityName> <adminUnit>Cayo</adminUnit> <country>Belize</country> <population>11100</population> <area>5</area> <elevation>130</elevation> <longitude>88.44</longitude> <latitude>17.27</latitude> <description>Belmopan is the capital of Belize</description> <history>Belmopan was established following the devastation of the former capital,Belize City, by Hurricane Hattie in 1965. High ground and open space influencedthe choice and ground-breaking began in 1966. By 1970 most government officesand operations had already moved to the new location. </history> </city> </tourGuide> Root Element Parent Element Child Elements

18. XML Rules The first line of an XML document must contain the prologue. The main theme of the XML document – the root element - must enclose all the other elements in the document. Every element must have an opening tag <> and a closing tag Elements must be properly nested, that is you close the tag that was opened last – think of tags as using a LIFO convention or more properly a LOFC Last Opened First Closed convention (though it doesn’t have quite the same ring to it). Elements can have attributes. –Attribute values are enclosed with “ ” and can have no spaces.

19. The XBRL Structure Tags –Description of what data is 1000 Attributes –Meta-data (data describing data) 1000 Relationships –Is something described as related to ?

20. XBRL – Lets put it all together Instance Document –Contain tags describing data Schema –Contains the definition of the tags LinkBases –Contains relationships between tags Taxonomy –Combination of Schemas (defining elements) and LinkBases (relating elements)

21. Types of LinkBases Presentation –How to organize output E.g. what tags make up Current Assets Calculation –How related tags are summed (+ or -) Definition –Different tag names are related for the same thing Inventory and Merchandise Inventory Reference –A tag element and the standard reference (FASB) for an element Label –Machine Readable to Human Readable CashAndCashEquivalents = Cash and Cash Equivalents
