• Cost of sales and services: Cost of sales and services increased 1.5% mainly due to the increase in the cost of network maintenance, partially offset by the change in the accounting policy for PC costs related to Internet services that took effect in January 2005, as well as lower charges in pensions and seniority premiums, travel expenses, costs of directories and settlement cost.

• Commercial, administrative and general: Commercial, administrative and general expenses decreased 1.4% in the quarter due to reductions in advertising expenses, lower charges in pensions and seniority premiums and other administrative costs.

• Transport and interconnection: Transport and interconnection costs decreased 13.4% due to the reduction of the calling party pays rate, the main component of this item.

• Depreciation and amortization: Depreciation and amortization decreased 10.9% due to a lower level of assets to be depreciated and to the impact of the exchange rate.
