Salary expenses decreased by 14.2% in 4Q03, to Ch$14,835 million (US$25.0 million), mainly due to the personnel restructuring realized in October, 2002.

Other operating costs and expenses decreased by 15.6% in 4Q03 as compared to 4Q02, to Ch$62,858 million (US$105.9 million). This decline is explained by lower rental capacity, lower uncollectables provision (-25.4%) and costs associated to the Istel subsidiary in the 4Q02.

Administrative and selling expenses increased by 29.6% to Ch$38,009 million (US$64.0 million), due to higher costs and sales commissions related to the mobile business, ADSL and corporate communications, as well as higher costs related to third-party contracts.

As a result of the above, EBITDA in 4Q03 grew slightly by 0.5% to Ch$95,746 million (US$161.2 million), compared to Ch$95,287 million (US$160.5 million) recorded in 4Q02. During 2003, EBITDA decreased 3.5%, reaching Ch$381,863 million (US$643.1 million), with respect to the previous year.

Depreciation of operating assets increased by 1.4% to Ch$65,974 million (US$111.1 million) in 4Q03 as compared to 4Q02, as a result of the Company's new assets in service and which are mainly related to the mobile business and data. During 2003, depreciation of operating assets remained constant at Ch$263,687 million (US$444.0 million). Total depreciation increased 4.5% with respect to 4Q02 and 1.0% for the year.

Lines per employee (excluding employees of Telefónica CTC Chile's subsidiaries), decreased from 1,050 in December 31, 2002, to 915 in December 31, 2003, explained by a 10% decrease of lines in service together with a 3.2% increase in headcount compared to December 2002.

Primary service revenues, which include the fixed monthly charge, variable charge, connections and other installations, value-added services and equipment marketing, and others (ADSL, IP flat fee, rural telephony, among others), decreased by 9.5% to Ch$84,582 million (US$142.4 million) in 4Q03 as compared to 4Q02. This decrease is mainly attributable to a 10.5% decrease in the fixed monthly charge and an 14.1% decrease in the variable charge due to: (i) the lower exchange rate which had a negative impact on the tariff indexator (ii) a 1% additional tariff decrease applied in May 2003 to variable and fixed charges pursuant to the Tariff Decree; (iii) a 9.0% decrease in average lines in service in 4Q03 vs. 4Q02, which resulted from increased disconnections in 4Q03 associated to non-payment, (iv) a 7.4% decrease in total traffic for 4Q03 compared to 4Q02, and (v) an increase in the proportion of traffic charged as fixed-Internet traffic, whose rates are lower than those of traffic rated as Measured Local Service (fixed-fixed calls). However, the above was partially offset by a 59.3% increase in revenues from equipment marketing which, as of January, include revenues from equipment sales to small and medium-sized enterprises. Previously, these revenues were included in corporate customer communication revenues. Additionally, other fixed telephony revenues grew 40.4% due to the growth in new services over the fixed line such as ADSL and flat fee plans.

Access charges and interconnections revenues include revenues from access charges generated by LD carriers, as well as those paid by other telecommunications operators that use Telefónica CTC Chile's network. They also include other interconnection services apart from access charges, such as interconnection of networks and information services to carriers, among others. These revenues increased by 41.1% in 4Q03 to Ch$8,151 million (US$13.7 million) as compared to 4Q02, mainly due to an increase of 123.9% in other interconnection services due to the payment of pending interconnection charges from other local operators and higher revenues from network services and interconnections. These increases were partially compensated by 14.2% lower of DLD access charges revenues and 30.8% lower in ILD access charges revenues, due to a 14.9% and 32.0% decrease in domestic and international interconnection traffic, respectively

Revenues from directory advertising, generated by the Company's contract with Publiguías, increased by 16.1% in 4Q03 to Ch$1,123 million (US$1.9 million) as compared to 4Q02.

Long distance revenues include revenues from domestic and international long distance traffic carried by 188 Telefónica Mundo and Globus 120, as well as revenues from the rental of the long distance network to other telecom operators. Total long distance revenues, which accounted for 6.3% of consolidated operating revenues in 4Q03, decreased by 32.9% as compared to 4Q02, to Ch$13,231 million (US$22.3 million). This decrease in revenues was mainly due to: (i) lower revenues from domestic long distance services ("DLD") due to the 4.3% decrease in DLD traffic carried by 188 Telefónica Mundo and Globus in 4Q03 as compared to 4Q02, in line with the DLD industry traffic trends and the substitution effect from mobile service, and (ii) lower revenues from international long distance services ("ILD") due to an 8.7% decrease in outgoing ILD traffic, together with a reduction of 6.9% in the average price of this service in 4Q03 vs. 4Q02 caused by increased competition, and (iii) lower revenues from the rental of the long distance network to other telecom operators due to lower prices and lower industry traffic in general. During the year, revenues declined 18.3% to Ch$61,655 million (US$103.8 million) and representing a 7.6% of total consolidated revenues.

Mobile communications revenues include revenues from outgoing cellular traffic and interconnection revenues from Calling Party Pays (incoming traffic to the mobile network), as well as revenues from mobile equipment sales. Total revenues from mobile communications, which accounted for 31.5% of total operating revenues in 4Q03, amounted to Ch$65,811 million (US$110.8 million), representing an increase of 14.5% as compared to 4Q02. This increase is mainly the result of a 17.1% increase in average cellular subscribers and also an increase in sales of prepaid equipments, which was partially offset by a decrease in the average monthly revenue per user ("ARPU"), due to an increase in the proportion of prepaid customers in Telefónica Móvil' s subscriber base. Prepaid customers represented 80.5% of total average cellular subscribers in 4Q03, as compared to 76.3% in 4Q02. As of December 31, 2003, Telefónica Móvil had 2,269,757 customers, of which, 421,698 are GSM customers. During 2003, revenues of mobile communications Ch$237,620 million (US$400.2 million) representing a 29.2% of total revenues for the year.

Corporate customer communications include revenues from (i) telecommunications equipment sales, which refers to voice equipment (fax, PABX, etc.); (ii) complementary telephone services, such as 600, 700, 800 numbers and digital communications; (iii) data services, including ATM, Frame Relay, data equipment and services related to the IP network, and (iv) dedicated links and others, including videoconference, Datared, E1 Links and VSAT, "ISP Empresas" revenues, services such as housing and hosting and consulting services to corporate customers.

Revenues from corporate customer communications decreased by 15.2% to Ch$21,373 million (US$36.0 million) in 4Q03 as compared to 4Q02. The contribution of corporate customer communications revenues to total operating revenues decreased from 11.7% in 4Q02 to 10.2% in 4Q03. This decrease was mainly due to 32.1% lower revenues in telecommunications equipment sales to small and medium-sized enterprises, which starting in January 2003, are accounted for under fixed telephony revenues. Excluding these revenues, corporate customer communications revenues increased 5.1%. Additionally, circuit revenues and others decreased 48.1% which was partially compensated by (i) a 47.3% increase in data services revenues in 4Q03 as compared to 4Q02 due to increased connectivity services through the IP network, and (ii) a 4.0% increase in complementary services to corporate customers. ATM links increased by 4.1% while data links through the IP network grew at a rate of 85.3% for dedicated IP network, and average customers decreased by 4.4% for switched IP network in 4Q03 as compared to 4Q02. For the year 2003, corporate communications revenues reached Ch$78,733 million (US$132.6 million), representing a 9.7% of total consolidated revenues for the period.

Interior installation and equipment marketing revenues increased by 7.3% in 4Q03 to Ch$8,070 million (US$13.6 million) compared to 4Q02.

Other businesses revenues, that include revenues from other subsidiaries such as Telemergencia and t-gestiona, among others, reached Ch$4,121 million (US$6.9 million) in 4Q03, with an 38.3% increase compared to 4Q02, mainly due to higher revenues from Telemergencia and partially offset by the sale of Istel.
