XBRL Pacific Rim Technology WorkShop & Summit Intern program Hiroaki Sakakibara Fujitsu Limited

Project Overview XBRL Formula With the release of the XBRL formula specification on June 22 nd this project will demonstrate the use of XBRL formula to identify errors in SEC filings. This project will require the intern to create XBRL formula based on assertions for SEC filers to check the validity of their instances. The intern is expected to identify aerations and create XBRL formula that will be made available on the XBRL US website for filers to run and check the validity of their filings with the US GAAP taxonomy. The deliverables from the project will be as follows: · Listing of assertions in an XBRL formula format · Test cases of existing filings showing errors in filings · Identification of problems and Issues with the formula specification

Agenda What’s XBRL Formula? What we can do with formula ? Assertion Formula What we can’t do with formula ? Conclusion

What’s XBRL Formula?  Assertion oExistence check for source item oValue check based on source items oConsistency check computed item to source item  Formula oResults in an fact item oFor an output instance document oFor consistency checking of corresponding input

Formula Linkbase (Assertion) Input Taxonomy Formula Linkbase* Input instance Formula Processor Assertions existence value consistency Assertions existence value consistency True False Evaluate Taxonomy and Instance according to defined assertion Type of assertions *Formula Linkbase is part of DTS

Type of Assertions

Input Taxonomy Formula Linkbase (Assertion/ Formula)* Formula Processor Variable Custom Function Parameter Filter What can be define? *Formula Linkbase is part of DTS True False Filter options such as “Context” Variable Filter Customized Parameters Fact Value to be asserted

What you can do with “Assertion”?  Customized criteria oValue check (accounting point of view) oConsistency check (summation item, BS vs SS, etc.)  Exposable Validator oUndependable on tools, the same criteria can be applied Input Taxonomy Formula Linkbase Formula Processor Assertions existence value, consistency Assertions existence value, consistency True False This linkbase can be used individually

Formula Linkbase (Formula) Input Taxonomy Formula Linkbase* Formula Computed items Input instance Output Taxonomy Output instance Formula Processor Mapping line items in designated taxonomy *Formula Linkbase is part of DTS

What you can do with “Formula”?  Interoperable in different types of GAAPs oMapping between GAAPs, might be able to solve accounting gaps  For Financial analysis oSimilar metadata can be used for modeling financial indicator Input Taxonomy Formula Linkbase Analytical model can be applied Output Taxonomy Formula Computed items Formula Processor Input instance Output instance

What we can’t do with Formula?  Assertion oCustom Defined Parameter for Complicated Assertion ( ex. SEC Validator, etc ) oTime consuming for Mapping Taxonomies  Formula oReverse conversion ( One way )  Common oFormula engine ( software, tools ) required oDifficult to use
