10 BCDL For Business Checks Description Language Evolutionof LEA (Languageto Express Assertions) currentlyusedin French SURFI system Used to define EIOPA assertions Simple arithmeticlanguageusing, as muchas possible, business concepts Example: [S h] Label = Geographical aggregation of assets in Benelux GlobalFilters = [!RingFencedFunds] Each assertion must have a code a clear label Assertion = Assets[Benelux] = Assets[Belgium] + Assets[Netherlands] + Assets[Luxembourg] 10

Example: [S.01.02.002h] Label = Geographical aggregation of assets in Benelux GlobalFilters = [!

11 How to help Different ways Using labels: " Assets" = "Currentassets" + "Non-currentassets" or using L3C names: Assets = AssetsCurrent + AssetsNonCurrent or, usingbusiness codes: E1 = E1A + E1B or, using XML codes: s2md:mi312 = s2md:mi451 + s2mdmi452 Business concepts must beunambiguouslymappedto taxonomy/ DPM concepts => problems Non-uniquenessof identification (problemof currentdpm withdimension members) Name spaces(xml or Reporting units) Length of business concepts labels 11
