Technological Innovations

Basis for Presentation of Results

The partial Bill & Keep (B&K) system was implemented in July 2003, under which payment for use of local network among SMP operators is not made unless traffic rate among them exceeds 55%, that causes an impact on interconnection revenue and cost.

The 2005 and 2004 accumulated numbers correspond the values between January and June of the mentioned years.

Some information disclosed for 2Q04, 1Q05 and accumulated 2004 were re-classified, as applicable, for comparison purposes. Figures disclosed are subject to differences, due to rounding-up procedures.

Consolidated TCO's Operating Highlights

• Continued market leadership as a result of the increase in the customer base by 32.3% in the last 12 months, despite strong competition in the cellular telephone market. It is important to also emphasize the conservative company's reckoning procedures.

• Net additions totaled 438 thousand customers, a 36.7% share, keeping the leadership with a 49.0% market share in 2Q05, in a period of strong commercial activity within the cellular telephone market.

• SAC increased by 38.6% in 2Q05 over 1Q05, as a result of the strong competition recorded in the period and the reduction in the value of "entry barriers" on a market with 4 operators.

• The churn at 1.5% recorded a drop of 0.5 p.p. in relation to 2Q04, thus confirming the result of the commercial practices adopted by the company, as for example the offer of several plans to promote customer loyalty.

• The blended ARPU of R$ 26.4 recorded a 0.8% reduction in relation to 1Q05, basically due to the growth in the post-paid ARPU by 4.8%, as well as an increase in the outgoing ARPU of the post-paid customer base. However, the year-to-year variation has shown a drop which is due to the customer mix effect, drop in inbound ARPU due to among other factors to the migration of the inbound traffic from fixed-mobile to mobile-mobile, in addition to the partial Bill & Keep effect and right planning programs (customer profile adequacy plans) effected in the post-paid service users base.

• The post-paid MOU increased by 2.9% and 3.9% in relation to 2Q04 and 1Q05, respectively, caused by the increase in the post-paid incoming MOU. On the other hand, the total MOU was impacted by the changes in the customer mix, once the prepaid MOU is impacted by the reduction in the fixed-mobile inbound traffic.

• The increase in the operation efficiency can be measured by the productivity increase of 48.1% and of 11.1% in relation to 2Q04 and 1Q05, respectively, due to the continuous search for obtaining organizational and process synergies, integration and efficiency.

Net Services Revenue

The net services revenue grew 7.2% in relation to 1Q05, recording R$ 498.4 million in the quarter and R$ 963.5 million between January and June of 2005, 9.9% above the same period of last year . Such growth is a consequence of the increase in the customer base greater use of data services, partially offset by the right planning effects and by the fact that the increase in the VU-M became effective only in June and was not adopted by all fixed operators. In relation to the same period of last year, a growth of 5.4% was recorded, having in mind that the increase in the interconnection tariff influenced over the whole period.

It must be highlighted that "subscription and usage revenue" recorded a 10.4% increase over 2Q04, due to the increase in the total outgoing traffic, which was partially offset by a reduction in the inbound traffic revenue, as a result of the transition from fixed-mobile traffic to mobile-mobile traffic, with consequent drop in interconnection revenue and the partial Bill & Keep effect.

Data revenues were up 40.0% in the year-to-year comparison, representing 5.6% of the net service revenues in 2Q05 (4.0% in 2Q04).

Personnel Cost

The increase in personnel cost in the comparison of year-to-date totals for 2005 and 2004 is a consequence of the salary adjustment provided for in the collective bargaining agreement, the investments in training and the incentive campaigns for the selling team.

Cost of Services Rendered

In 2Q05, the 27.3% increase in the cost of services rendered in relation to the previous quarter is a result of the increase in the number of links and negotiations of connection means, in addition to the increase in the customer base that impacts the interconnection cost. The variation recorded in "Fistel and other fees and contributions" in relation to 2Q04 arises out of equalization of TCO's accounting criteria to the other Group Companies.

Cost of Goods
Sold

The cost of goods sold increased by 97.9% in relation to 1Q05, mainly due to a higher number of activated handsets (gross additions increased by 60.8%) and also due to the costs inherent to incentive for change of TDMA into CDMA terminals.

Depreciation and Amortization

Depreciation and amortization expenses increased 6.0% in 2Q05 in relation to the previous quarter and this is due to the investments effected, specially in function of the overlay to the CDMA network.

The net financial revenue in 2Q05 increased by R$ 6.0 million when compared to 1Q05, specially due to the increase in the interest rate in the period (4.18% in 1Q05 and 4.56% in 2Q05), which had a positive impact over TCO's net cash position.

The seasonal disbursements in 1Q05 (handsets purchased for the 2004 Christmas' campaign and the Fistel Fee – TFF annually paid in March) allied to cash generation resulting from a better working capital management obtained in 2Q05, made possible the net cash increase in 2Q05.
