4. The solution : Central Server for Statistical Reporting a single IT software tool implemented on server(s) connected to the Internet dedicated to all kinds of statistical and prudential reports used by all kinds of reporting agents (financial, non-financial, public, private, big or small companies) to report to different authorities (central bank, supervisors, NSI)

5. IT : Life cycle of statistics & CSSR conception implementation data collection & first validation control & data correction production & quality control dissemination of results & broadcasting ==> very thin tool in the production chain but very efficient by its level of functionalities } CSSR

6. Scope of CSSR Many statistical domains Many domains for supervision Many surveys - many forms Different reporting frequencies Many sectors of activity Several languages (FR, NL, DE & EN) => For the declarants A single IT solution for all reportings A single IT solution for big, small, financial & non-financial companies A declarant must use only one IT software for all reportings

8. General Principles Internet standards-based application : HTTP, SMTP, S/MIME Thin client architecture : only browser at client side, no NBB- software NBB does not intervene in the automation at client side One central validation-server at the NBB Support different profiles of users : low-profile, semi-automated and full-automated Support different levels of security : 'strong' and 'weak' secured Client is responsible for follow-up and quality of his reporting Immediate validation of his reporting Adequate functions to do this follow-up Same philosophy for many reportings

9. General Principles Reporting agents receives their own 'space' on the server input for a survey can be done over several days to finish the reporting, they have to 'close' the questionnaire Multilingual application Business areas are responsible for the business logic software is managed by the business areas the application contains functions to define new surveys, forms, validation- and derivation rules without intervention of the IT-department Short 'time to market' for new questionnaire

10. Input Channels On-line data entry : 'Web-forms' Layout and content of Webform is determined by end-users Import of CSV-files Synchronous or asynchronous treatment Format of the csv-file is similar to the corresponding Web-form Http file upload XML format, one or many 'tables' Asynchronous treatment Client gets a validation report via e-mail Mail exchange Strong secured : data is encrypted and digitally signed (S/MIME) For certain reportings, non-secure mail is authorised under the responsibility of the client. Control on the 'from address'

11. Input Channels XBRL (IFRS, Bazel II, FINREP) integrated in the content part of our proprietary XML format

12. Advantages for the reporting agent A single tool A single address A single userID/certificate A single interface Multilingual software No software, no installation, no costs No interference between CSSR and the internal organisation of the reporting agent Validation reports (on-line or off-line)

13. Advantages for the central Bank or the Supervisor A single IT software No software distribution No support - officially only one browser supported (I.E. v 5.0) New release on demand & when needed Savings on costs of data entry, time to produce the results Higher quality thanks to integrated checks Software fully managed by the statisticians Reducing the "time to market"

14. IT: Functionalities for the reporting agent Web page interface with forms Edit, Save, Delete, Validate functions File upload On-line validation On-line totalisation Standard print of forms Private memory space to store temporary data Identification of the contact persons Delegation of access authorisation Follow-up tool (control board) E-mail upload and off-line validation report

15. Functionalities for the statisticians & the supervisors Domain definition Survey definition Code table, classification & list definition (meta-data) Definition, maintenance & update of validation & calculation rules Population Management Which companies have to report what for which period within which prescribed time limit Follow-up of response calculation of response rate / non-response rate / average delay for reporting preparation of reminder

20. © National Bank of Belgium There are no limitations in the reporting protocol with regard to: the number of referenced taxonomies (templates); the number of facts, contexts or periods. So, within one document it is possible to report: facts for all taxonomies for one period. facts for one / more taxonomies for several periods. (very) limited sets of concepts, possibly even concept per concept, for corrections or revisions. XBRL and the CSSR

30. © National Bank of Belgium Calculation linkbase: only straightforward, simple calculations No inequalities. No multiplications. No exceptions. No cross-context. Formula linkbase no recommendation yet IT: additional rules outside taxonomy CSSR - business rules

31. © National Bank of Belgium Business rules outside of taxonomy : for (CPT=="ifrs_gp:AvailableForSaleFinancialAssetsAccumulatedImpairmentLosses") group [DIMPROPS], CPT {VAL>=0;} for all group [DIMPROPS] {if (((VAL(CPT=="be_ifrs_fi:SpecificAllowancesForIndividuallyAssessedFinancialAssets") + VAL(CPT=="be_ifrs_fi:SpecificAllowancesForCollectivelyAssessedFinancialAssets")) !=0) then (VAL(CPT=="be_ifrs_fi:CarryingAmountOfTheImpairedAsset") ==0));} for CPT == "p_cm_ca:MarketRiskCapitalRequirements" and MR=="d_mr:MRiskSACOMTotal" group [DIMPROPS]- ["COM"],CPT {VAL(COM==null) ~== sum(VAL(exist(COM)));} Everything is possible! Rules are very intuitive! Reporter-dependent! CSSR - business rules

32. © National Bank of Belgium XBRL is highly flexible. CSSR allows to take full advantage of this flexibility by working at concept level. XBRL calculations are too limited. Until formula linkbase is available, all possible business rules can be programmed and validated by CSSR. Afterwards, CSSR can be used to add additional features (exceptions, tolerances,...). Manual entry form is available in CSSR and is based on taxo. In the medium term, everything can be put in the taxonomy (instructions, business rules,...). Simply load the taxonomy in the CSSR and make it available to the reporting agents! Transparancy, maintenance, new reporting projects,... Validation before submission: "zero error" reports should be submitted "Management by Exception" XBRL and the CSSR, very well integrated and a strong combination!

33. CSSR : Conclusions single software multi-reporting agents & multi-users multi-domains, multi-surveys, multi-forms multilevel functionalities (small or big companies) multilevel security multilingual multi-authorities (National Bank, Supervisor, National Accounts) only used by Belgian authorities ==> Why not widen the use of CSSR to other authorities in charge of statistical & prudential data collection?

36. CSSR : Internationalisation Advantages for cooperators Availability of a high level solution in the short term Teething problems have already been overcome Confidentiality of the data totally guaranteed NBB - IT infrastructure is up to date, including disaster recovery procedure CSSR development conforms to the state of the art in IT business Costs saving - greatest part of the investments already made Costs sharing of the IT platform between the countries using CSSR depending on the volume needed by each country Possibility to add new domains of data collection when needed => good learning curve & very low costs to start the project
