Reception of XBRL reports in : New French regulations, complete change of the reporting system : SURFI (Unified FInancial Reporting System), all banking reporting for prudential and statistical needs of Banque de France, will be done in XBRL, the SURFI taxonomy and SURFI application are developed

Web forms Applicable only to small set of data – Will certainly not be implemented for Solvency II reporting in ACP May be a way to view the data sent to the regulator – But ACP sends back Excel sheets containing the data and showing the errors May be a way to correct (slightly) invalid reports Imply a cost to create forms from taxonomy / regulatory templates – The Table linkbase will help May be used for the signature of reports for small filers (view the reported data, then sign)

Excel to XBRL conversion tool Some small filers use solutions based on Excel (specially in the insurance sector) An Excel to XBRL conversion tool may be an alternative to Web forms (some offers provide both solutions) – Possibility to fill the forms with Excel API (e.g.: ActiveX)
