1. KBC Group New segment reporting, pro forma figures 2005

2. 2 Changes in reporting: background information KBC has restated its 2005 quarterly figures to comply with: The retro-active application of ‘portfolio hedge accounting’ (carve-out’) in Q4 2005 1 Its new segment reporting approach The retro-active application of the principles of ‘portfolio hedging’ includes that: the financial impact of it (previously booked as a lump-sum amount in Q4 2005) is allocated to the relevant 2005 quarters (this has a negative impact of 40 m on the Q2 results, fully offset by the positive impact on the Q3 results (7 m) and the Q4 results (33 m) The segment reporting changes are explained on the following slide 1 Restatement of the P&L lines ‘Net gains from financial instruments at fair value’ and ‘taxes’ REMINDER

3. 3 1 An exception has to be made for KBC Bank NV and KBC Insurance NV Belgium’s activities Changes in segment reporting: background information New business unit structure as major segment reporting criterion (i.e. Retail Belgium, CEE, European private banking, Merchant Banking, Group Centre) Disclosure of area of activity results in a full P&L format (which was not the case before) Full allocation of results of each subsidiary to a single segment 1 No further imputation of impact of capital ‘normalisation’ adjustments on segment bottom-line. In return, funding costs of goodwill related to equity participations will be allocated to the relevant segments Further restatements of historical time series Limitation of number of ‘Group Center’ items to: results of holding company non-allocated expenses of other entities that can be deemed holding-company overheads (e.g., strategic consultancy fees, BoD expenses, ‘group-level’ operating provisions, etc.) results of co-sourcing vehicles (such as e.g. Fin-Force - as a rule, expenditure is covered by service users, so, barring timing differences, impact on bottom line tends to be immaterial results of equity holdings within investment portfolio of banking business REMINDER
