Consolidated Operating Costs

The Cost of Services Provided, General & Administrative Expenses and Selling Expenses, (excluding ‘Results on disposal of PP&E, writedown of PP&E and related assets’ that resulted in a loss of P$165 million), totaled P$10,501 million in 1H13, an increase of P$1,993 million, or +23% vs. 1H12. The increase is a consequence of higher commercial costs, higher taxes related to the increase in sales, the inflationary effects in the general cost structure, and greater expenses related to the intense competition.

The cost breakdown is as follows:

•   Employee benefit expenses and severance payments totaled P$1,873 million (+26% vs. 1H12), mainly affected by increases in salaries granted to the unionized employees, increases to the non-unionized workforce, together with the social security contributions associated with such concepts, and to an increase in the number of unionized employees.

•   Taxes and fees with regulatory authorities reached P$1,248 million (+33% vs. 1H12), impacted mainly by a higher volume of revenues, a higher incidence in turnover taxes derived from increases in municipal jurisdictions, higher municipal taxes and higher taxes with the regulatory authority.

•   Interconnection costs and other telecommunication charges (includes TLRD, Roaming, Interconnection, international settlement charges and lease of circuits) amounted to P$1,006 million, +25% vs. 1H12. This increase resulted from higher Data and SMS roaming costs as well as voice roaming and TLRD charges due to a higher volume of traffic of minutes, partially compensated by savings arising from on-net traffic stimulation.

•   Commissions (Commissions paid to Agents, prepaid card commissions and others) totaled P$1,024 million (+14% vs. 1H12), mainly due to the increase in commissions paid to commercial agents associated with the increase in sales. Agent commissions capitalized as SAC amounted to P$218 million (+42% vs. 1H12).

Consolidated Costs

% Revenues

•  Advertising amounted to P$286 million (-9% vs. 1H12), mainly explained by minor commercial expenses and campaigns in comparison to 1H12 when Mobile Number Portability was introduced.

•  Cost of handsets sold totaled P$1,288 million (+34% vs. 1H12), due to an increase in high-end handsets sales at higher unit prices, following the strategy of stimulating VAS usage, partially compensated by a lower quantity of handset sold. Deferred costs from SAC amounted to P$164 million (-33% vs. 1H12).

•  Fees for services, maintenance and materials amounted to $1,214 million (+20% vs. 1H12), principally due to increases in the maintenance of radiobases, systems and real estate in the mobile business and higher costs associated to suppliers in both fixed and mobile segments.

•  Depreciations and Amortizations reached P$1,399 million (+11% vs. 1H12). PP&E depreciation amounted to P$955 million (+10% vs. 1H12); SAC and services connection costs amortization totaled P$432 million (+14% vs. 1H12); and other intangible assets amortization reached P$12 million (+9% vs. 1H12).

•  Other Costs totaled P$1,163 million (+40% vs. 1H12).

Bad debt expenses reached P$165 million (+11% vs. 1H12) representing 1.6% of consolidated costs, while charges related to lawsuits and other contingencies amounted to P$97 million in 1H13 (+64% vs. 1H12).

Consolidated Financial Results

Financial Results resulted in a gain of P$214 million, an increase of P$102 million or +91% vs. 1H12. This was mainly due to a gain in net financial interest of P$253 million in 1H13 (+P$131 million vs. 1H12) based on a healthy financial position and to losses for FX results of P$62 million in 1H13 (vs. losses of P$15 million in 1H12).

The main capital expenditures in the fixed business, were associated to the reconversion plan of the network that implies the replacement of copper with fiber optic cables in different points (FTTC or Fiber to the cabinet, FTTB or Fiber to the building and FTTH or Fiber to the home) also complemented with new access technologies (VDSL/GPON) allowing broadband speeds to reach up to 100 Mbps. This evolution to new architectures and technologies provides higher speeds and optimizes service quality in terms of stability and availability, improving the customer experience.

In the mobile business, the technological reconversion plan of the network continues with the optimization of 2G and 3G/HSPA+ services in all the country, increasing capacity spectrum usage efficiency. It is expected to double the capacity of the 3G network in 2013.
