Of which: 

Where: 

		
		= tariff proposed in the Basic Plan for National Long-Distance Services for time j, in the i distance tariff step, net of taxes levied.

	 	 
		= tariff prevailing in the Basic Plan for National Long-Distance Services for time j, in the i distance tariff step, net of taxes levied. 

		
		 = minutes of the National Long-Distance Service noted in the Basic Plan for National Long-Distance Services in time j, in the i distance tariff step, since the last tariff adjustment. 

MT = total minutes of the National Long-Distance Service noted in the Basic Plan for National Long-Distance Services since the last tariff adjustment. 

i = distance tariff step of the National Long-Distance Service included in the Service Tariff Structure. 

j = tariff time of the National Long-Distance Service included in the Service Tariff Structure. 

t = proposed date for adjustment. 

to = last adjustment date; and 

Where: 

IST = tariff adjustment ratio, composed based on existing price ratios, pursuant to regulation. 

X = transfer factor 

FA = repayment factor.

data related to the national long-distance minute, as well as material, personal, services and depreciation factors. 

     Paragraph 2. As from January 1, 2008 the X transfer factor shall be defined by Anatel based on a methodology that considers the optimization of service provision costs, pursuant to regulation. 

     Paragraph 3. In the event the value resulting from the calculation of the X transfer fact is negative, the value zero (0) shall be adopted. 

     Paragraph 4. The repayment factor value is: 

I – zero (0) for IST variations, in the period under analysis, up to ten percent (10%); 

II – one hundredth (0.01) for IST variations, in the period under analysis, higher than ten percent (10%) and up to twenty percent (20%). 

III – two hundredth (0.02) for IST variations, in the period under analysis, higher than twenty percent (20%). 

     Paragraph 5. In the event the adjustment period involves different transfer factors values, a weighted average considering the months of levy of each transfer factor value shall be calculated for its application.

     Paragraph 6. In the event the last adjustment date is earlier than the date this Agreement came into effect, the adjustment shall be progressively applied taking into account the periods involved and the
respective prevailing formulas and criteria. 

     Paragraph 7. In the event the adjustment is applied in periods over twelve months, the formula in which the transfer factor is included shall be progressively applied taking into account twelve-month periods and,
finally, any residual months, if any.

party’s or the service users’ expense shall be barred, pursuant to the provisions in this Chapter.

initial financial position by the Insurance Plan set forth in clause 24.1.

expansion or generation of alternative or supplementary 

revenues associated to the service subject to this Agreement, subject to current competitive conditions.

     Sole Paragraph. The decrease in revenues arising from discounts or reduced tariffs shall not give rise to tariff review.
