		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	%

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.   In addition, within the scope of the annual tariff adjustment, that reflects the pass-through of some costs components incurred by the
