Net Revenues

Table 1 – Breakdown of Net Revenues

(1) In 4Q16, the Company revised and changed the criteria for segmenting revenues and revenue generating units (RGUs) among the various business units (BUs), as it believes this new breakdown better reflects how the businesses are managed. Historical revenue and RGU figures were adjusted in order to reflect this change. To see the reclassified historical data, please refer to the Additional Information section of this document.

In 1Q17, consolidated net revenues totaled R$ 6,160 million, -8.8% y.o.y. and -2.6% q.o.q. Net revenues from Brazilian operations (“Brazil”) came to R$ 6,066 million (-7.2% y.o.y. and -0.7% q.o.q.), while net revenues from other international operations (Africa and East Timor) totaled R$ 94 million (-56.7% y.o.y. and -55.9% q.o.q.), basically due to the reduction of the participation of one of the Company's firms in the capital stock of Namibian telecommunications operator Mobile Telecommunications Limited, in January 2017, as announced to the market on January 31, 2017.

In 1Q17, net revenues from Brazilian operations totaled R$ 6,066 million, 7.2% down from 1Q16 and 0.7% down from the previous quarter. The y.o.y. reduction was chiefly due to the cut in the interconnection (MTR, TU-RL and TU-RIU) and fixed-to-mobile (VC) regulated tariffs, the lower customer base, the decline in recharges in the prepaid segment and the reduction in revenues from the B2B segment, with these two segments being impacted by the adverse macroeconomic scenario and the unemployment rates in the country, affecting companies and governments.

On the other hand, revenues from the Residential segment grew both in the annual and quarterly comparisons, fueled by broadband and pay-TV growth, and supported by the Company’s convergence strategy. In addition, customer revenues from the Personal Mobility segment grew 1.1% compared with the previous quarter, due to the postpaid revenues performance leveraged by the growth of data revenues.

Total net service revenues, which exclude handset revenues, stood at R$ 6,009 million in 1Q17, 7.3% down from 1Q16 and 0.7% down from 4Q16. Total net customer revenues, which exclude network usage and handset revenues, came to R$ 5,794 million, 5.9% lower than in 1Q16 and practically in line with 4Q16.

Residential

(1) In 4Q16, the Company revised and changed the criteria for segmenting revenues and revenue generating units (RGUs) among the various business units (BUs), as it believes this new breakdown better reflects how the businesses are managed. Historical revenue and RGU figures were adjusted in order to reflect this change. To see the reclassified historical data, please refer to the Additional Information section of this document.

Net revenues from the Residential segment totaled R$ 2,354 million in 1Q17 (+0.2% y.o.y. and +1.7% q.o.q.), mainly due to growth in broadband and pay-TV revenues, which offset the effects of the annual reduction in regulated interconnection (TU-RL and TU-RIU) and fixed-to-mobile (VC) tariffs and the lower fixed line base.

It is worth noting that customer revenues (which exclude interconnection revenues) in the Residential segment recorded 1.7% y.o.y. growth for the fourth consecutive quarter. It is also worth mentioning the q.o.q. growth (+1.6%) after two quarters of sequential decline. The better result was due to lower levels of net disconnections in fixed line, combined with an increase in broadband and pay TV net adds. This trend is a result of the convergence strategy, which, together with increased customer profitability, has been supporting the growth of Residential revenues.

In 1Q17, Oi registered 16,343 thousand RGUs in the Residential segment, 1.7% down from 1Q16, maintaining the trend of slowing year-on-year base reduction (-7.1% in 4Q15, -6.2% in 1Q16, -4.4% in 2Q16, -3.1% in 3Q16 and -2.1% in 4Q16). This slowdown was due to continued growth of gross adds in the three products of the segment, as a result of the Company’s convergence strategy, reflected in the increase and high adhesion of customers to Oi’s main convergent offer, Oi Total. This offer was designed to generate customer loyalty and profitability of our base, offering more products to households.

Residential ARPU

Residential ARPU moved up 5.8% y.o.y. and 3.1% q.o.q. to R$ 79.6 in 1Q17, driven by broadband and pay TV, whose ARPU climbed 4.8% and 8.3%, respectively, over 1Q17, and also a results of the increase in the percentage of higher value customers and with more than one Oi product in their residence.

Fixed line

Oi ended 1Q17 with 9,802 thousand fixed line customers in the Residential segment, 5.2% down from 1Q16 and 1.5% lower than in 4Q16. It is important to mention the trend of slowing year-on-year fixed line base reduction, (-9.3% in 4Q15, -8.5% in 1Q16, -7.1% in 2Q16, -6.2% in 3Q16 and -5.4% in 4Q16), thanks to the growth of convergent offers. In 1Q17, gross adds grew a substantial 15.6% y.o.y. and 6.1% q.o.q.

The share of low-end offers in fixed line gross adds continued to decline in 1Q17 (-8.5 p.p. y.o.y. and -4.7 p.p. q.o.q.).

As a result of the focus of sales on convergent offers, Oi Total has been recording increases in its base, therefore expanding its share on Residential fixed base. At the end of 1Q17, the offer totaled 1.2 million customers corresponding to a share of 11.9% of the fixed base, and the Oi Total Residential (3P) offer had a churn rate 48.1% lower than the one recorded by the standalone offering. It is worth noting that Oi Total’s customer base surpassed the mark of one million customers in February 2017, less than one year after its national launch. This offer is appealing due to its complete and fully convergent solution, from sales to customer care and billing, at competitive prices.

After the nationwide launch of Oi Total in March 2016, the Company discontinued the sales of the former convergent offer, Oi Conta Total (OCT), which combined fixed line, broadband and mobility. Although the OCT base has been retained, the Company began an organic migration process to Oi Total, following a customer retention plan with profitability. Consequently, in 1Q17, 49.6% of Oi Total Solução Completa (4P)’s total gross were to former OCT (3P) customers, demonstrating an important initiative to increase customer profitability by adding more products to the customer's bill. Oi Total and OCT together accounted for 17.9% of the fixed base in 1Q17, increasing 5.5 p.p. over 1Q16.

Oi Voz Total (OVT), a convergent offer that combines fixed line and prepaid mobile, accounted for 12.1% of the Residential fixed line base in the end of the quarter, with a churn rate 33.4% lower than the one recorded by the standalone fixed line offer. The lower churn rates of convergent offers compared with those of standalone products underline the relevance of convergence to build customer loyalty.

Broadband

The Company closed 1Q17 with 5,204 thousand fixed line customers in the Residential segment (+1.7% y.o.y. and +0.3% q.o.q.). At the end of the quarter, broadband gross adds grew 16.6% over 1Q16 and 6.9% over 4Q16, reaching their highest level since 4Q13. This increase in gross adds contributed to the growth of the broadband base, and consequently, the Company continued to present net adds in 1Q17 (of 16 thousand RGUs in the quarter and 89 thousand RGUs in the last 12 months). Broadband penetration in households with Oi fixed line reached 53.1% in the quarter (+3.6 p.p. y.o.y. and +0.9 p.p. q.o.q.).

Oi’s strategy of increasing profitability by concentrating efforts on high-end offers led to the decrease of the share of low-end offers in gross adds, maintaining the downward trend (-6.5 p.p. y.o.y. and -0.8 p.p. q.o.q.). The delivery of higher broadband speed enabled by VDSL technology (broadband with speeds of up to 35 Mbps) has been boosting Oi Total sales and fueling the share of high-end offers in Oi’s base. This reflects directly in the increase in broadband ARPU, which moved up 4.8% between 1Q16 and 1Q17.

The average speed of broadband customers reached 7.2 Mbps at the end of 1Q17 (+24.4% y.o.y. and +5.4% q.o.q.). The share of RGUs with speeds starting at 5 Mbps increased 9.3 p.p. over 1Q16 to 72.3%, while the share of RGUs with speeds starting at 10 Mbps increased 11.8 p.p. to 46.4% in the same period. Also, the share of RGUs with speeds starting at 15 Mbps moved up 8.8 p.p. over 1Q16 to 15.5% this quarter.

It is worth highlighting that the average speed of gross adds reached 9.6 Mbps (+26.9% y.o.y. and +2.3% q.o.q.), due to the Company’s network investments aiming to offer higher speeds, thus providing a better user experience. In 1Q17, 84.7% of gross adds had speeds starting at 5 Mbps (+7.6 p.p. y.o.y.), 64.0% had speeds starting at 10 Mbps (+10.1 p.p. y.o.y.) and 36.2% had speeds starting at 15 Mbps (+23.4 p.p. y.o.y.).

Pay TV

Oi closed 1Q17 with 1,336 thousand pay-TV RGUs in the Residential segment, accelerating its annual growth rate (+14.4% y.o.y. and +3.6% q.o.q.) and registering growth for the 13^th consecutive month. As a result, Oi had the best performance among the major economic groups in this market in the annual comparison, expanding its share of the total pay-TV market from 6.2% in 1Q16 to 7.3% in 1Q17. It is worth mentioning that Oi TV plays an important role in the convergence strategy in the Residential segment and, thanks to its distinction, has contributed to Oi Total’s good acceptance, as the Company’s main convergent offer.

Pay TV has also been recording consistent y.o.y. growth in gross adds, moving up considerably 34.5% over 1Q16. Churn rate fell 0.1 p.p. in the same comparison. As a result, net adds totaled 168 thousand RGUs in 12 months and 46 thousand RGUs in the quarter. It is worth noting that Oi was the operator with the highest growth in the pay-TV market in the last 12 months.

As a result of the Company’s strategy of increasing customer profitability, Oi TV’s penetration in households with Oi fixed line continued to grow, reaching 13.6% in 1Q17 (+2.3 p.p. y.o.y. and +0.7 p.p. q.o.q.). Both Oi TV’s superior quality and the strong sales performance of the Oi Total convergent offer contributed to increase the share of TV high-end offers by 4.3 p.p. y.o.y. to 28.4%. The intensification of sales of high-end offers has been sustaining Oi’s consistent ARPU growth, climbing 8.3% over 1Q16.

Oi TV offers a full content, with high-definition channels (including open channels) in all of its plans and the most complete offer provides up to 184 channels, 60 of which are in HD. The product also offers services like PenVR (content recording and live/pause service via pen drive available in any plan) and iPPV (purchase of Pay-Per-View events by remote control), in addition to TV Everywhere, a service that allows customers to watch content from 46 channels, including 27 with live content and more than 30 thousand on-demand titles, from any device (smartphone, tablet or PC) connected to the Internet at no additional cost. This service, which includes the Oi Play virtual platform, reinforces Oi’s positioning in providing more user autonomy and a better customer experience through the digitalization of its services.

In order to cater to the different user profiles, the Company also offers a prepaid service for Oi TV, in which customers have the option to share credits between their mobile phones and pay TV, with a choice between biweekly or monthly recharges (beginning at R$ 29.90 and R$ 54.90, respectively), which can be paid by credit card or through sharing the customer’s mobile credits.

Personal Mobility

(1) In 4Q16, the Company revised and changed the criteria for segmenting revenues and revenue generating units (RGUs) among the various business units (BUs), as it believes this new breakdown better reflects how the businesses are managed. Historical revenue and RGU figures were adjusted in order to reflect this change. To see the reclassified historical data, please refer to the Additional Information section of this document.

(2) Excludes handset and network usage revenues.

(3) Includes postpaid plans, Oi Controle, bundled mobile services and 3G (mini-modem).

Net revenues from the Personal Mobility segment totaled R$ 1,947 million in 1Q17, a 3.9% y.o.y. reduction, substantially lower than the annual decline reported last quarter (-6.9%). Revenues were virtually in line with the previous quarter (+0.1%).

The year-on-year decline in net revenues from the Personal Mobility segment was mainly due to (i) the reduction in the volume of recharges in the  prepaid segment influenced by high unemployment rates; and (ii) the reduction in network usage revenues, as a result of the annual cut in interconnection tariffs (MTR).

In 1Q17, customer revenues, which exclude interconnection and handsets, totaled R$ 1,748 million, 1.7% down from 1Q16. Postpaid + control segments stood out in this quarter, with a y.o.y. growth of 14.5% in revenues (excluding long-distance revenues), but was offset by the annual decline in prepaid revenues, which fell 8.3% (also excluding long-distance revenues). The prepaid segment is still being impacted by the uncertain macroeconomic scenario and the high unemployment rate, which discourage mainly prepaid customers from recharging. In the sequential comparison, customer revenues registered a 1.1% growth, due to the increase in postpaid + control revenues (+8.2%), which outpaced the reduction in prepaid revenues (-3.8%).

Data revenues climbed 10.7% over 1Q16 to R$ 947 million. This amount accounted for 54.1% of total customer revenues in the quarter (+6.1 p.p. versus 1Q16), thanks to the high penetration of smartphones in the customer base, the focus on high-end offers (Oi Livre, Oi Mais and Oi Mais Controle) featuring more extensive data allowances.

In 1Q17, network usage revenues fell 25.3% y.o.y. to R$ 141 million, due to the regulated MTR cut. In February 2016, interconnection tariffs (MTR) fell to R$ 0.09317, R$ 0.10309 and R$ 0.11218 in Regions I, II and III, respectively. In February 2017, these same tariffs declined to R$ 0.04928, R$ 0.05387 and R$ 0.06816 in Regions I, II and III, respectively. Based on the future cuts approved by ANATEL, MTR tariffs will be as follows: (i) in 2018: R$ 0.02606, R$ 0.02815 and R$ 0.04141; and (ii) in 2019: R$ 0.01379, R$ 0.01471 and R$ 0.02517 in Regions I, II and III, respectively.

Handset revenues fell 2.7% y.o.y. to R$ 57 million in 1Q17. Smartphones accounted for 100% of sales in the quarter.

Oi closed 1Q17 with 39,837 thousand RGUs in the Personal Mobility segment, 12.6% down from 1Q16 and 0.1% lower than in 4Q16. In 1Q17, net disconnections totaled approximately 32 thousand, comprising 40 thousand net disconnections in the prepaid segment and 7 thousand net additions in the postpaid segment. The Personal Mobility customer base reflects the decline in the Prepaid segment in the country, and this is due to the macroeconomic scenario and the chip consolidation movement itself, which is a consequence of the drop in MTR and the increase in the use of messaging and text tools.

Oi’s mobile customer base (Personal Mobility + B2B) reached 42,100 thousand RGUs in 1Q17, 39,837 thousand of which in the Personal Mobility segment and 2,263 thousand in the B2B segment. Gross adds totaled 4.4 million, while net disconnections came to 60 thousand in 1Q17.

Prepaid

The prepaid customer base came to 32,957 thousand RGUs in 1Q17, 14.8% down y.o.y., mainly due to the tough macroeconomic environment and the high unemployment rates in the country (13.7% as of March 2017). However, despite this challenging scenario, the customer base remained virtually flat (-0.1%) compared with the previous quarter, as did recharge volume per business day and the recharger base (number of active prepaid customers who make recharges). These results were due to adjustments to the Oi Livre offer, that were launched in December 2016, which, besides offering an extensive data allowance and a single tariff for calls to any operator anywhere in the country (all-net model), also provides customers a higher use flexibility (recharge expiration varying according to the recharge value), higher all-net allowances and more benefits.

In April 2017, Oi launched, in the Oi Livre (and Oi Mais Controle) offer, an unprecedented functionality that allows customers to choose whether they will use voice minutes or data directly on the Minha Oi app, with no exchange limits or additional costs. This functionality adjusts to users’ different profiles and needs, offering more practicality and independence by providing digital tools that allow them to satisfy their demands more quickly and with greater autonomy, therefore improving customer experience.

At the end of the quarter, Oi Livre accounted for 50% of the total prepaid base (45% in 4Q16), with an average ticket 25.9% higher than that of other offers.

Postpaid

Oi closed the quarter with 6,880 thousand RGUs in the postpaid segment, virtually in line with 1Q16 (-0.2%) and 4Q16 (+0.1%), increasing its share of the total Personal Mobility customer base from 15.1% in 1Q16 to 17.3% in 1Q17. It is important to highlight the annual postpaid ARPU growth (ex-MTR) of 9.3%, as a result of increased data revenues and the focus on increasing customer profitability.

Currently, the main offers in the postpaid segment are Oi Mais and Oi Mais Controle, with a more extensive data allowance with no use restrictions, as well as reduced single tariffs and minute allowances to call any operator anywhere in the country. In 1Q17, customers who adhered to Oi Mais and Oi Mais Controle accounted for 45% of the total postpaid + control base (38% in 4Q16). ARPU from Oi Mais customers was 21% higher than that of customers from other plans, while ARPU from Oi Mais Controle was 52% higher in 1Q17, underlining the offers’ success in increasing customer profitability.

2G, 3G and 4G LTE Coverage 

Oi’s 2G coverage reached 3,404 municipalities in 1Q17 (93% of the country’s urban population), while 3G coverage reached 1,488 municipalities (+12.9% y.o.y.), or 80% of the Brazilian urban population. 

In the end of 1Q17, 4G LTE coverage reached 284 municipalities, or 62.5% of Brazil’s urban population, 11.1 p.p. up on 1Q16.

Oi is working in partnership with other operators in the sharing of the 3G/4G network, in order to optimize its investments and reduce costs while seeking to consistently improve the quality of services and customer experience. The efforts to improve its 3G and 4G network capacity and coverage quality have allowed consistent growth of data traffic in the network, meeting the growing demand for data while improving ANATEL’s network quality metrics.

Mobile ARPU

In 1Q17, mobile ARPU stood at R$ 16.2, 8.0% up on 1Q16 and 4.5% higher than in 4Q16. Excluding interconnection revenues, mobile ARPU increased 10.5% y.o.y.

Since last quarter, the Company began reporting mobile ARPU excluding revenues from traffic between Oi’s mobile and fixed line divisions (intercompany), but including revenues from mobile long-distance calls in total mobile service revenues (Personal Mobility + B2B). This amount is then divided by the average customer base (Personal Mobility + B2B) to calculate the Company’s mobile ARPU.

B2B

(1) In 4Q16, the Company revised and changed the criteria for segmenting revenues and revenue generating units (RGUs) among the various business units (BUs), as it believes this new breakdown better reflects how the businesses are managed. Historical revenue and RGU figures were adjusted in order to reflect this change. To see the reclassified historical data, please refer to the Additional Information section of this document.

(2) Includes postpaid plans, Oi Controle, bundled mobile services and 3G (mini-modem).

Net revenues in the B2B segment amounted to R$ 1,703 million in 1Q17, 17.7% lower y.o.y and 4.9% lower q.o.q. The annual variation was impacted by additional service contracts and by agreements with operators in 1Q16. Excluding this effect, the annual decrease would have been 10.2%., due to the Brazilian macroeconomic scenario, which has been impacting the B2B market as a whole, and the cut in regulated interconnection (MTR) and fixed-to-mobile (VC) tariffs.

Despite the negative external effect in the segment, Oi has been presenting continuous evolution in the quality of services and customer experience, as can be seen in the indicators of average time of installation and volume of billing complaints. For large companies, average time of installation fell by 33.8% while billing complaints fell by 51.9%, both in the annual comparison. As for SMEs, average time of installation fell by 41.0% and billing complaints fell by 35.8% in the same comparison.

The Company recorded 6,550 thousand RGUs in the B2B segment in 1Q17 (-1.8% y.o.y. and -1.0% q.o.q.).

Corporate

The economic slowdown in Brazil has been impact directly impacting Oi’s Corporate segment. Private customers and mixed economy companies have sought to reduce costs, while state and municipal governments, which account for a large share of Oi’s Corporate revenues, have reduced contracts, investments and new projects, as a result of the financial crisis in the public sector.

On the other hand, the segment has been presenting growth in non-traditional revenues, such as data and IT services, thus reducing its dependence on voice services (fixed line and mobile), which have been losing their appeal in the corporate market, as mentioned before. In 1Q17, the data, IT and value-added services offered by the Company, such as VPN networks, cloud services, ICT, datacenter, home office, management services, security solutions and M2M (Machine-to-Machine), continued to grow, accounting for 70.4% of Corporate revenues (+2.9 p.p. y.o.y.).

SMEs

The Brazilian macroeconomic scenario has also been impacting the SMEs segment, affecting credit risk for these companies. Nevertheless, this segment has been presenting improvements in its operational indicators, including gwoth of 17.4% in sales, a 35.8% decline in the volume of billing complaints and a 5.9% increase in the ARPU of mobile gross adds, all of which compared with the same period last year. These improvements were mainly due to simplification of the offer portfolio and to digitalization, which contributed to improve customer experience.

In the SMEs segment, digitalization is represented  by the Oi Mais Empresas app, which offers a fully digital customer service channel that allows customers to acquire services, contract plan upgrades, make complaints and request bill copies and repairs, among others, all via smartphone. More than 237 thousand small and medium enterprises have adhered to the new offering portfolio and are benefiting from the app, which has a user satisfaction level of 87%, 77% of the requests completed within the deadline and a Net Promoter Score (which measures the percentage of customers who would recommend Oi to other companies) of 65%. 

Oi Mais Empresas features mobile plans with 4G data and fixed line at a fixed monthly fee (flat fee model), which allows higher cash flow predictability. This offer currently represents 39% of the fixed line customer base and 40% of the mobile customer base of this segment.

Operating Costs and Expenses

Table 2 – Breakdown of Operating Costs and Expenses

In 1Q17, consolidated routine opex, including international operations, totaled R$ 4,437 million, 10.9% down y.o.y. and 2.8% lower q.o.q.

Routine opex in Brazilian operations totaled R$ 4,374 million in 1Q17 (-9.9% y.o.y. and -1.4% q.o.q.). Considering inflation (IPCA) of 4.6% in the last twelve months, this result corresponded to a decrease of almost 14% in real terms, compared to 1Q16.

Personnel

In 1Q17, personnel costs and expenses in Brazil totaled R$ 642 million, 2.2% lower than in 1Q16, mainly due to the reduce of workforce in 2016, partially offset by absorption of operations of network service providers that took place last year and by salary readjustments following the collective bargaining agreement. In the sequential comparison, these costs moved up 2.0% basically due to the collective bargaining agreement in the period.

Interconnection

Interconnection costs in Brazil ended 1Q17 at R$ 231 million, 33.6% down y.o.y. and 21.1% lower q.o.q., as a result of the interconnection (MTR, TU-RL and TU-RIU) tariff cuts, which took place in February 2016 and 2017, partially offset by the increase in off-net traffic volume, as a result of the Company’s new offers based on the all-net model.

Third-party Services

In 1Q17, costs and expenses related to third-party services in Brazilian operations totaled R$ 1,557 million, 2.8% up on 1Q16, as a result of the contractual readjustment of TV content and of higher expenses with sales that were partially offset by lower expenses with call centers, due to the improvement of the quality of services, and also due to reduced electricity expenses. Compared with 4Q16, these costs moved up 1.5%, mainly due to higher expenses with sales and electricity (system of tariff flags), but partially offset by the reduction of call center related costs, in line with the advances in service quality, as previously mentioned.

In 2016, the Company implemented a customer service quality model based on a competition logic between Oi’s call center providers for higher traffic shares, granted based upon proven service quality. This model encourages the improvement in service quality by all players. In addition, Oi launched the Cuidar do Cliente” (Caring for the Customer) program, with the purpose of promoting a cultural change from serving to caring, with training initiatives, tools, process improvements and proactive actions based on customers’ voice.

These changes on customer service contributed to efficiency improvements observed in several indicators, such as an 8% annual drop in customer service costs and a 16% decline in the volume of repeated calls during the same period. As a result, Oi’s customer satisfaction index increased by 13% and the number of customer service complaints filed with ANATEL dropped by 41%.

Network Maintenance Services

Network maintenance service costs and expenses in Brazil totaled R$ 281 million in 1Q17, 41.2% down y.o.y., due to lower expenditures with network service providers as a result of the absorption of their operations in 2016.

These incorporations have allowed the Company to reduce the number of repairs per customer (-16.2% y.o.y.), increase productivity (+19.4% y.o.y.) and lower operating costs due to a 26.1% annual reduction in the number of field technicians. As a result, Oi has been improving in several operational indicators, including (i) a 44.4% reduction in the average waiting time for resolution, (ii) a 12.6% increase in compliance with the schedule of visits, and (iii) a 36.6% drop in the average time until the installation of a service, all in the comparison between 1Q16 and 1Q17. The improvement in these indicators had a direct impact on the reduction in complaints in ANATEL for technical reasons (-44.3% in the same period).

Compared with 4Q16, these costs increased 4.6%, mainly due to the incorporation of technical support by the operations department.

Handset Costs/Other (COGS)

In 1Q17, handset costs in Brazilian operations amounted to R$ 73 million, in line with the previous quarter (R$ 71 million) and 17.6% up y.o.y., due to higher handset sales volume this quarter.

Marketing expenses totaled R$ 61 million in 1Q17, 30.1% lower than in 1Q16, when the Company launched its main offer, Oi Total, nationwide. The q.o.q. reduction in these costs reflects the seasonal effect of Christmas campaigns in December, 2016.

Rent and Insurance

Rent and insurance expenses in Brazilian operations totaled R$ 1,061 million in 1Q17, -2.2% y.o.y., chiefly due to (i) the exchange variation in the period, which reduced leasing infrastructure data transmission costs, such as satellites, partially offset by higher costs with vehicles, following the absorption of network service providers and higher tower and equipment leasing costs. In the sequential comparison, rent and insurance expenses in Brazilian operations fell 3.3%, due to the settlement of accounts with other operators in 4Q16, related to the leasing of towers and equipment.

Provision for Contingencies

The provision for contingencies in Brazilian operations totaled R$ 110 million in 1Q17, -46.4% y.o.y. and -15.9% q.o.q., basically due to the lower number of claims in the JEC (Special Civil Court) and the reduction in the average claim amount.

Provision for Bad Debt

The provision for bad debt totaled R$ 159 million in 1Q17, virtually in line with 4Q16 and 25.6% up y.o.y., due to a lower atypical provision for bad debt level in 1Q16. The provision for bad debt represented 2.6% of net revenues from Brazilian operations in the quarter, the same level recorded in the last quarters.

EBITDA

Table 3 – EBITDA and EBITDA margin

In 1Q17, consolidated routine EBITDA totaled R$ 1,723 million, 3.0% down y.o.y. and 1.9% down q.o.q. Routine EBITDA from Brazilian operations amounted to R$ 1,692 million in 1Q17 (+0.4% y.o.y. and +1.0% q.o.q.), supported by cost-cutting and operational efficiency efforts, while the routine EBITDA margin in Brazilian operations stood at 27.9% (+2.1 p.p. y.o.y. and +0.5 p.p. q.o.q.).

Routine EBITDA from other international operations (Africa and East Timor) ended 1Q17 at R$ 31 million (-65.5% y.o.y. and -61.8% q.o.q.), due to the reduction in the interest held by one of Oi’s companies in the capital stock of the Namibian telecom operator, Mobile Telecommunications Limited, in January 2017, as released in the notice to the market on January 31, 2017.

Capex

Table 4 – Capex

In 1Q17, the Company’s consolidated investments totaled R$ 1,267 million (+1.1% y.o.y. and -9.0% q.o.q.). Capex in Brazilian operations came to R$ 1,227 million, 1.9% up y.o.y., due to higher investments in the modernization and expansion of network capacity and IT, designed to increase operational efficiency and promote continuous improvement in service quality and customer experience, with direct impact in the generation of value for the business.

The increase in the capacity of the Company’s networks has sustained the rise in data traffic and improved the quality of fixed, mobile and pay-TV services, while enabling Oi to continue to launch new offers better suited for customers’ needs.

In the mobile network, Oi has moved forward with the development of 3G and 4G access networks and structural actions in the network core. Regarding the fixed line network, Oi continues to develop structural infrastructure projects, mainly with the expansion and modernization of the transportation network backbone, as well as initiatives to modernize and optimize the access network capacity.

As a result, data and voice access indicators continue to increase, as well as ANATEL indicators on data connection and data drop rates, confirming the improvement of the quality of services and customer experience. As a result, Oi continued to record advances in its network indicators, underlining the improvement in service quality and customer experience. As an example, the data access indicator registered a 2 p.p. increase between the end of 4Q15 and the end of 1Q17, reaching 97.4% of access. Also, ANATEL indicators that measure data connection rate (SMP8) and data connection drop rate (SMP9) also continued to evolve, closing the 1Q17 levels above the target required by ANATEL.

Operational Cash Flow (Routine EBITDA – Capex)

Table 5 - Operational Cash Flow

Table 6 - Operational Cash Flow from Brazilian Operations

Consolidated routine operational cash flow (routine EBITDA minus Capex, or OCF) totaled R$ 456 million in 1Q17, 12.8% down y.o.y. and 25.3% up q.o.q. Routine EBITDA minus Capex in Brazilian operations totaled R$ 465 million in 1Q17, -3.4% y.o.y., mainly because Capex growth outpaced the increase in routine EBITDA in the period. In the sequential comparison, there was a 46.4% increase.

Depreciation / Amortization

In 1Q17, the Company reported depreciation and amortization expenses of R$ 1,519 million (-6.9% y.o.y. and -1.9% q.o.q.).

Financial Results

Table 8 – Financial Results (Oi S.A. Consolidated)

In 1Q17, Oi S.A. recorded a net financial expense of R$ 115 million, 63.4% lower than in 4Q16 and 93.9% down y.o.y. The reduction in the net financial expense this quarter was chiefly due to the R$ 357 million decline in “Other Financial Income / Expenses”, resulting from higher revenues from the monetary restatement of judicial deposits, lower taxes and lower exchange variation expenses on foreign investments.

Additionally, the Company presented financial income in the "Net FX Result" item for another quarter, explained by the appreciation of the Real against the Dollar (2.8%) and the Euro (1.4%) in 1Q17, resulting in a positive impact of the exchange variation on debt. Comparing to 4Q16, this item reduced 18.4% due to the positive impact of the exchange variation in that quarter, which was higher than in 1Q17 (5.6% of appreciation of the Real against the Euro, and a slight 0.4% depreciation against the Dollar).

In 1Q17, the “Net Interest” item remained virtually flat compared with the previous quarter, due to lower interest expenses on debt indexed to the CDI and the positive impact of the above-mentioned appreciation of the Real on debt denominated in foreign currency, offset by higher expenses related to debt indexed to the IPCA inflation index and higher net interest expenses from international operations (Africa).

In the annual comparison, the substantial reduction of R$ 1,903 million in the financial result was due to: (i) the positive impact of the above-mentioned appreciation of the Real, added to the fact that the Company has been exposed to exchange rate fluctuations due to the absence of derivative instruments since mid-2016, which resulted in a positive exchange variation on debt denominated in foreign currency; (ii) the decline in the “Net Interest” item due to lower interest expenses on debt indexed to the IPCA inflation index and debt denominated in foreign currency, in addition to higher financial income due to higher average onshore capital (investments indexed to the CDI rate); and (iii) the R$ 91 million positive variation in “Other Financial Income / Expenses“, mainly due to the monetary restatement gain in judicial deposits.

Net Earnings (Loss)

Table 9 – Net Earnings (Loss) (Oi S.A. Consolidated)⁽¹⁾

(1) 1Q16 data were restated as explained in the Disclaimer section of this document.

In the quarter, the Company's operating income before financial income and taxes (EBIT) was positive in R$ 204 million, a 52.1% increase over the positive R$ 134 million recorded in 1Q16, due to lower depreciation and amortization expenses. In 1Q17, Oi posted a consolidated net loss of R$ 200 million, presenting a significant reduction of 89.0% when compared to the net loss of R$ 1,815 million reported in 1Q16, as a result of the positive impact of the financial result explained above.

Debt & Liquidity

Table 10 - Debt

Oi S.A. ended 1Q17 with consolidated gross debt of R$ 48,308 million, an increase of R$ 117 million comparing to the previous quarter. Compared with 1Q16, consolidated gross debt fell 2.2%, or R$ 1,063 million.

Comparing to 4Q16, the increase in gross debt was driven by another quarter of accrual of interest and by the suspension of interest payments and of the amortization of principal of loans and financing of the Company due to the Judicial Reorganization process. This effect was partially offset by the appreciation of the Real against the Dollar (2.8%) and the Euro (1.4%) in the period, which impacts the fully exposed portion of debt denominated in foreign currency.

In relation to 1Q16, the reduction in gross debt was mainly due to the appreciation of the Real against the Dollar (11.0%) and Euro (16.4%), affecting the fully exposed portion of debt denominated in foreign currency, and due to the amortizations of principal and interest totaling R$ 8,133 million made before the request for judicial reorganization, on June 20, 2016. These effects more than offset the debt increase arising from interest accrual and the suspension of interest payments and the amortization of principal of loans and financing after the filing of the request for judicial reorganization.

At the end of 1Q17, net debt stood at R$ 40,608 million, 0.7% up q.o.q., driven by both a slight increase in gross debt and the R$ 150 million reduction in cash in the quarter. The cash decrease was due to a non-recurring regulatory obligation (Fistel fee), in the amount of R$ 660 million. It is worth mentioning that, excluding this annual payment of the Fistel fee, the Company would have recorded cash generation of R$ 510 million.

Compared with the same period last year, net debt fell 0.6% or R$ 236 million, mostly concentrated in the second half of 2016. Since the end of June 2016, the Company has been recording positive operational cash generation. The cash accumulation, combined with the effect of the appreciation of the Real surpassed the negative impact of interest accrual on net debt in the period.

Historical Reclassified Net Revenues and Revenue Generating Units (RGUs)

In 4Q16, the Company revised and changed the criteria for segmenting revenues and revenue generating units (RGUs) among the various business units (BUs), as it believes this new breakdown better reflects how the businesses are managed. Historical revenue and RGU figures were adjusted in order to reflect this change. The historical reclassified data are shown in the tables below:
