European Banking Authority (EBA) EBA consultation paper, 2011-12-20 Reporting shall be done in accordance with the specifications included in the Data Point Model and the XBRL taxonomies, Data Point Model: structured formal representation of the data, identifying all the business concepts and its relations, as well as validation rules, oriented to all kind of implementers.

9. 9 XBRL EBA Workshop – Nov ‘07 “The same information should be produced only once” as such, certain elements have been defined as common i.e. : Elements requested by the 3 mains regulators (CB, CBFA, CSSF) Elements requested by the holding (in the consolidated financial statements)

15. 15 DEFINITIONS Data point = Base item [Dimension(member), Dimension(member)…] Base item = Conceptual meaning: asset, liability, capital, exposure … Dimension= Breakdown / Disaggregation: Country, Counterparty Member = Each “value” of a dimension: Cash, Loans, Shares… Asset [Type(Shares), Country(UK), Counterparty(Corporations)] Method If two cells in the reporting framework are disaggregations, breakdowns, or share characteristics of the same business concept, the differences are to be expressed as members of dimensions. At the end of the process, only a few of “pure” base items and a number of dimensional members are defined to express in a combinational structure the original regulatory framework.

17. 17 Total number of potential data points = ∏ n i i=1 to d Total number of members ≤ ∑ n i i=1 to d ∏ n i i=1 to d ∑ n i i=1 to d ________________ d _ n = ∑ n i i=1 to d n i = number of members of the dimension i d = number of dimensions _nd ≈_nd ≈ _ _ and dn << n d Typically << as it is equivalent to: ∏ n i i=1 to d Data Point Model progression

18. 18 Main Properties: 1.Arithmetic progression in the number of members creates data points exponentially 2.Each cell defines one data point; each data point is defined by one cell (at least). 3.Each dimension would be used only zero or one times in each data point 4.A member would be shared among several dimensions 5.The dimensional expression is commutative
