AUP and F&R engagements

AUP engagements-overview Auditors are not required (or expected) to:  Read, perform procedures, assess, or issue separate assurance on the XBRL exhibit or controls Agreed-upon procedures (AUP) engagements are separate from the audit and are less in scope than an audit or review – no assurance is provided.  The objective is to perform procedures in order for management to evaluate the completeness, accuracy and consistency of the XBRL data  Findings represents errors, alternatives, observations and recommendations Procedures can be customized, but usually focus on:  Tagging selection – use of the taxonomy and extensions  Areas the SEC has identified as frequently having errors (e.g. signs, decimals, date contexts, etc)  Company should evaluate whether findings would improve the XBRL submission and make final judgment related to potential changes Level of effort:  Typical block text engagement takes 2–3 elapsed weeks and ranges from 50–90hours  Typical initial detail tagging engagements takes 4–5 elapsed weeks and ranges from 150–250 hours  Reoccurring engagements take considerably less time Volume of findings:  Typical detail tagging engagement averages more than 150 comments, with companies making changes on most of the commented areas 4

AUP engagements - common errors observed Not tagging all required information  Parenthetical information, amounts in superscript footnotes, amounts written out (e.g., twenty percent), not tagging all amounts in the notes/schedules (detail tagging)  Line items that have a non-determinable value (e.g., commitments and contingencies)  Missing required S-X schedules, not including all required levels  Not tagging all of the dimensions (e.g., missing dimensions represented in narrative) Tag selection  Extending tags unnecessarily or selecting the wrong standard tag  Not using required tags or selecting different tags for the same amount and concept that appear more than one time in the financial statements Other tag related errors  Wrong signs for the values (i.e., positive versus negative), wrong reporting period dates, wrong decimal settings or wrong amounts (i.e., proper number of zeros),  Wrong or missing calculations, wrong or missing units of measure  Incomplete information provided for extensions tags (e.g., missing debit or credit balances, as required)  Not using XBRL footnote links, as required 5
