17. 17 Accounting Effects It is management’s intention to effect the write-off of the goodwill amount resulting from this transaction in the fiscal year of 2006. It is estimated that ITAÚ ’s net income will be reduced by R$ 2.2 billion, net of taxes, as a result of the amortization of goodwill. The amount of dividends/interest on own capital to be distributed to the pro forma ITAÚ shareholder base for the fiscal year 2006 will not be impacted by this amortization of goodwill and should, therefore, be higher than those paid out in 2005; The transaction is expected to be EPS accretive in the second half of 2007; The Basle Ratio, pro forma for the acquisition, will equal approximately 16.7%.

18. 18 Impact of the Transaction on Itaúsa Decline in stake in ITAÚ from 48.2% to 45.4% (R$ 0.4 billion); Gain from the equity method due to capital increase at ITAÚ (R$ 2.0 billion); Negative impact of goodwill amortization at ITAÚ (R$ 1.0 billion); ESTIMATED POSITIVE NET EFFECT ON NET INCOME (R$ 0.6 BILLION).
