This final review results from the amendment of Escelsa’s regulated asset base, depreciation rate and operating costs of the reference company, as shown in the table below: Final Figures for the Tariff Revision of August 2004
	R$ million	Provisional		Final
	Gross Regulated Asset Base	1,644		2,094
	Net Regulated Asset Base	921		928
	Depreciation Rate (%)	4.45	%	4.25	%
	Costs of Reference Company	216		217
	Tariff Repositioning (%)	6.33	%	8.58	%

	This review impacts the tariff base defined in August 2004, which is the starting date of the regulatory period ending August 2007. The retroactive impact of this review on Escelsa’s operating results, between August 2004 and August 2005, amounts to R$17.2 million (€6 million), and will be recovered through the tariffs until August 7, 2006.
