In 2Q18, consolidated net revenues totaled R\$ 5,545 million, down 5.0% from 2Q17 and 2.2% from 1Q18. Net revenues from Brazilian operations ("Brazil") came to R\$ 5,490 million (-5.2% y.o.y. and -2.4% q.o.q.), while net revenues from international operations (Africa and East Timor) stood at R\$ 55 million (+17.8% y.o.y. and +20.1% q.o.q.).

BRAZIL

Net revenues from Brazilian operations totaled R\$ 5,490 million in 2Q18, -5.2% y.o.y. and -2.4% q.o.q.. These reductions are explained mainly by: (i) drop in voice traffic, affecting the Residential and Personal Mobility segments; (ii) the cut in the regulated interconnection (MTR, TU-RL and TU-RIU) and fixed-to-mobile (VC) tariffs; and (iii) high unemployment rate, negatively affecting the prepaid recharge volume and the recharger base. The growth in pay-TV revenues from the Residential segment and data revenues partially offset these negative impacts in the year.

It is important to note that, in 2Q18, the net revenue declines in the Residential and B2B segments were softened, showing the beginning of a recovery, due to the acceleration of commercial activity, the good performance of the new offerings, both in Mobility and in Residential segments and improvement in the quality of the service provided.

Total net service revenues, which exclude handset revenues, stood at R\$ 5,452 million in 2Q18 (-4.9% y.o.y. and -2.2% q.o.q.), while total net customer revenues, which exclude handset and network usage revenues, came to R\$ 5,280 million (-5.3% y.o.y. and -1.8% q.o.q.). These changes were also caused by the above mentioned reasons.

Net revenues from the Residential segment totaled R\$ 2,114 million in 2Q18, which means the annual revenue decline is slowing down (-6.5% in 1Q18 versus 1Q17 and -5.1% in 2Q18 versus 2Q17). The downturn reflects the reduction in the customer base, mainly driven by fixed lines, the decline in fixed voice trafficand the annual cut in the regulated interconnection (MTR, TU-RL and TU-RIU) and fixed-to-mobile (VC) tariffs. This drop was partially offset by a 15.3% increase in pay-TV revenues over 2Q18. In comparison with the previous quarter, Residential revenues fell 3.9%.

Oi ended 2Q18 with 15,413 thousand RGUs in the Residential segment, a decrease of 5.3% over 2Q17 and of 1.2% over the previous quarter, due to the reduction in the broadband and fixed line customer base, the latter as a result of the natural market trend of reducing voice usage.

The Company has been working on adjusting plans in certain customer segments, i.e. it has been segmenting offers in order to compete with local providers in small and medium-sized cities and reduce churn and default risk.

Residential ARPU

Residential ARPU totaled R\$ 79.4 in 2Q18, up 3.7% over 2Q17, mainly driven by pay-TV ARPU (+4.0% y.o.y.), as well as the growing share of convergent offers in the base, with a continued increase in the number of households with more than one Oi product (+2.1 p.p. y.o.y. and +0.6 p.p. q.o.q.).

Fixed line

Oi ended 2Q18 with 8,821 thousand fixed line RGUs in the Residential segment, down 8.7% from 2Q17 and 2.0% from 1Q18. This decline reflects the market trend of reducing demand for voice services and, in order to mitigate this impact, the Company has been concentrating its sales efforts on more profitable high-end bundled offers. In 2Q18, revenues from bundled products climbed 43.1% over 2Q17 and Oi Total closed the quarter with approximately 2.9 million customers, as its customer base increased 16.0% over 1Q18, accounting for 32.5% of the fixed line base at the end of the quarter. The share of low-end offerings in fixed line gross adds continued to fall in 2Q18.

Convergent offers are designed not only to increase profitability in the Residential segment, but also to build customer loyalty and reduce churn rates. At the end of 2Q18, Oi Total Residencial (3P) had a churn rate 26.9% lower than the one recorded by the standalone offering, while the Oi Voz Total (OVT) offer, which still

accounted for 8.6% of the fixed line base in the segment, recorded a churn rate 14.4% lower than that of the standalone offering.

Earnings Release 3T14 Oi has been expanding unlimited fixed plans in the fixed line base, especially in Oi Total offers, reaching 44.1% of the total fixed line base, 7.0 p.p. more than in 2Q17.

In May 2018, the Company changed Oi Total, offering new customers who acquire the postpaid product as part of the Oi Total combo twice the Internet allowance of the standalone plan and a wide range of valueadded services (including audiobooks, BTFIT, PlayKids, Para Aprender, Oi Revistas and Te Ligou PRO). All offers include up to 15 MB broadband and unlimited fixed line calls to any operator in Brazil. These new offers are designed to meet the growing demand of users for data and attract high-end gross adds.

Broadband

Oi ended 2Q18 with 5,049 thousand fixed broadband RGUs in the Residential segment (-3.3% y.o.y. and -0.4% q.o.q.). The advance of competition, especially from local players operating in small towns outside of large urban centers, has been the biggest obstacle for the growth of the product.

As a short-term strategy to reverse the base decline, Oi has been using the NBA (Next Best Action) tool to monetize existing assets with selective business actions, launch regionalized bundle offers, review retention strategies, among others. These actions started at the end of the first quarter of 2018, and over the second quarter it is possible to see a reversal tendency in revenue begins to show positive signs of.

Regarding the highest value offers , Oi invests in VDSL technology (broadband with speeds of up to 35 Mbps), which boosts Oi Total sales, thereby increasing the share of high-end offers featuring higher speeds in the base. In addition, Oi is adopting a new approach to fiber deployment, called reuse, to deliver fiber to the customer's home more quickly and efficiently than the traditional way to deploy FTTH. Thus, the Company has been recording a consistently increasing broadband penetration in households with an Oi fixed line, which reached 57.2% in 2Q18 (+3.2 p.p. y.o.y. and +0.7 p.p. q.o.q.).

In 2Q18, the average speed of the broadband base reached 8.9 Mbps, an increase of 18.1% over 2Q17 and 3.4% over 1Q18. The share of RGUs with speeds starting at 5 Mbps increased 7.2 p.p. over 2Q17 to 81.4%, while the share of RGUs with speeds starting at 10 Mbps grew 10.4 p.p. to 59.6% and the share of RGUs with speeds starting at 15 Mbps rose 10.9 p.p. to 29.1% in the same period. It is worth mentioning that the average speed of broadband gross adds remained at 10.7 Mbps in 2Q18 (+8.8% y.o.y.). In 2Q18, 70.6% of gross adds had speeds starting at 10 Mbps (+5.2 p.p. y.o.y.) and 47.2% had speeds starting at 15 Mbps (+8.3 p.p. y.o.y.).

Pay TV

In 2Q18, the Residential Pay TV base maintained growth rates showed in recent quarters (+10.6% y.o.y. and +2.0% q.o.q.), reaching 1,544 thousand pay-TV RGUs. In the same period, pay-TV net adds totaled 148 thousand RGUs compared to 2Q17 and 30 thousand RGUs compared to 1Q18. Oi TV's penetration in households with an Oi fixed line reached 17.5% in 2Q18 (+3.0 p.p. y.o.y. and +0.7 p.p. q.o.q.).

Oi TV plays an essential role in the strategy of convergence in the Residential segment and has been fueling the growth of Oi Total sales. Oi TV is a differentiated product that offers a wide range of content, with highdefinition channels (including open channels) in all its plans, with the most complete offer providing up to 185 channels, 65 of which in HD. It also offers services like PenVR (content recording and live/pause service via

Earnings Release 3T14 pen drive available in any plan) and iPPV (purchase of Pay-Per-View events by remote control), as well as TV Everywhere, which allows customers to watch content from 50 channels, including 29 with live content. TV Everywhere includes the Oi Play virtual platform, reinforcing Oi's positioning in providing more user autonomy and a better customer experience through the digitalization of services.

In order to cater to the different user profiles, the Company also offers an Oi TV prepaid service, with a choice between biweekly or monthly recharges (beginning at R\$ 44.90 and R\$ 69.90, respectively), which can be paid by credit card or through sharing the customer's mobile or pay-TV credits, or via a bar code available on 10631 (and, from October, also via Minha Oi).

Personal Mobility net revenues totaled R\$ 1,793 million in 2Q18, which means that the downward trend is slowing down, as net revenues fell 4.2% year on year this quarter, versus 6.7% in the previous quarter. In the sequential comparison, net revenues fell 1.2%, versus 3.8% in 1Q18.

Despite the year-over-year net revenues reduction, in the quarter-over-quarter analysis, it is possible to see a reversal of the downward trend of the revenues. In prepaid, a product that corresponded to 80.7% of the total Personal Mobility base at the end of 2Q18, revenue grew in the sequential comparison, in line with the evolution of the country's unemployment rate. Regarding the postpaid segment, revenue also increased in the sequential comparison, stimulated by the mothers' day offer and growth in net additions.

Despite limited investment in 4G, which affects mostly the postpaid segment, Oi has been adopting the strategy of offering free content and a better digital experience to customers. As a result, in the quarter, net additions increased substantially, reaching 194 thousand in 2Q18 versus 2Q17 and 259 thousand in 2Q18 versus 1Q18. Additionally, the number of calls requesting cancellation fell 21.3% in 2Q18 comparing to 2Q17. Portability data shows a 79.3% annual decline in net disconnections, which means that the balance, even if negative, between the acquisition and loss of competitors' customers has shown significant improvement.

Earnings Release 3T14 Customer revenues, which exclude interconnection and handset revenues, totaled R\$ 1,638 million in 2Q18, down 4.4% from 2Q17, which represents a slowdown in the downward trend compared to the 6.5% reduction recorded in 1Q18. In the sequential comparison, customer revenues edged up 0.2%, reinforcing the success of the Oi Mais Digital offering, launched in April of this year, in which the market started to see relative value gain in the product, contributing to net adds continuing its growth trend this quarter.

Data revenues came to R\$ 1,109 million, an increase of 13.8% over 2Q17 and 7.0% over 1Q18, accounting for 67.7% of total customer revenues in the quarter (it was 56.9% in 2Q17 and 63.3% in 1Q18). Oi's offerings offer ever-larger data packets, reaching up to 30GB in postpaid offers. There are also resources that allow the customers, and Oi Mais Controle, Control and Oi Mais Digital. Furthermore, since May 2018, Oi launched the option to share allowances between Oi Mais Digital plan members in the postpaid segment, enabling users to transfer data between plan members and acquire additional packages, according to their needs.

In 2Q18, network usage revenues totaled R\$ 117 million, 16.7% more than in 2Q17, due to increased traffic, which more than offset the regulated MTR cuts. Network usage revenues fell 11.7% from 1Q18, mainly due to the regulated MTR cuts. In February 2018, interconnection tariffs (MTR) fell to R\$ 0.02606, R\$ 0.02815 and R\$ 0.04141 in Regions I, II and III, respectively. ANATEL approved the following future cuts for 2019: R\$ 0.01379, R\$ 0.01471 and R\$ 0.02517 in Regions I, II and III, respectively.

Handset revenues totaled R\$ 37 million in 2Q18 (-36.1% y.o.y. and -20.7% q.o.q.); smartphones accounted for 100% of sales and 98% of the handsets sold were 4G, whose penetration in the base increased 22.0 p.p. over 2Q17 and 4.0 p.p. over 1Q18.

Oi closed 2Q18 with 36,477 thousand RGUs in the Personal Mobility segment, down 8.4% from 2Q17, or 3,326 thousand net disconnections, comprising 3,520 thousand net disconnections in the prepaid segment and 194 thousand net additions in the postpaid segment. However, in the sequential comparison, Oi recorded a reversal in the trend, with a slight increase in the base (0.1%), with 43 thousand net additions, comprising 216 thousand net disconnections in the prepaid segment and 259 thousand net additions in the postpaid segment.

Oi's mobile customer total base (Personal Mobility + B2B) reached 38,883 thousand RGUs in 2Q18, 36,477 thousand of which in the Personal Mobility segment and 2,407 thousand in the B2B segment. Gross adds in the mobile segment totaled 4.1 million, while net adds came to 79 thousand compared with the previous quarter.

Prepaid

The prepaid customer base closed 2Q18 with 29,443 thousand RGUs (-10.7% y.o.y. and -0.7% q.o.q.). The yearover-year reduction was due to the policy of disconnection of inactive customers. Although prepaid is a product with high correlation with the country's unemployment rate, which despite the slight improvement in the quarter it remains high, it is worth noting that the total number of recharges per number of inserts increased in annual (3.3%) and sequential (2.8%) comparison, contributing to revenue performance.

In 2Q18, the segment had a small reduction in net revenue (excluding long-distance revenues) comparing to 2Q17 and a 0.9% increase comparing to the previous quarter, due to the slight improvement in the unemployment rate in the period.

Earnings Release 3T14 The main prepaid offer, Oi Livre, accounted for 70.2% of the base and has an average ticket higher than that of other prepaid offers. This offer has been successfully increasing customer profitability by driving prepaid ARPU up 8.4% over 2Q17 and 1.0% over 1Q18, fueled by higher data revenues in the segment. Oi Livre also offers extensive data allowances in the all-net model. Oi Livre customers can choose whether they will use voice minutes or data directly on the Minha Oi app, with no exchange limits or additional costs.

Postpaid

Oi closed the quarter with 7,033 thousand RGUs in the postpaid + control segment (+2.8% y.o.y. and +3.8% q.o.q.). In 2Q18, the postpaid base accounted for 19.3% of the Personal Mobility base, versus 17.2% in 2Q17 and 18.6% in 1Q18.

In this quarter, the postpaid + control segment recorded gross adds, resulting in positive net adds both over 2Q17 (194 thousand RGUs) and over (259 thousand RGUs).

In 2Q18, postpaid + control revenue (excluding long distance) increased by 0.9% over 1Q18, reversing the downward trend observed in the last two quarters.

The main offers of the segment, Oi Mais and Oi Mais Controle, has been contributing to increase the profitability of the base. In 2Q18, the average ARPU of Oi Mais customers was 11% higher than that of other postpaid customers, while ARPU of Oi Mais Controle was 36% higher than that of other control customers. These offers are very attractive by offering high data franchises and voice franchises to call any national operator at competitive rates on the market. Oi updated its Oi Mais Controle portfolio in May 2018, offering all new control customers unlimited calls to any operator in the country, in addition to the contracted internet allowance (3GB, 4GB or 6GB). The offer also enables customers to expand their internet allowance by up to 1GB, converting unlimited calls into data, which will be added to the allowance, through Minha Oi's benefit exchange functionality. Oi Mais Controle also offers value-added services including news and cooking content.

In April 2018, Oi also launched a new feature for Oi Mais Digital postpaid plans, allowing subscribers to manage their families' data usage, share data with up to four dependents and digitally manage the allowances of all users of the plan at any time, on the Minha Oi self-service app using their mobile phones or the internet. All offers feature unlimited calls to fixed and mobile phones of any operator in the country.

2G, 3G and 4G LTE Coverage

Oi's 2G coverage reached 3,407 municipalities at the end of 2Q18 (93% of the country's urban population), while 3G coverage reached 1,629 municipalities (+9.0% y.o.y.), or 81.6% of the Brazilian urban population.

In 2Q18, 4G LTE coverage reached 834 municipalities (+192% y.o.y.), or 74% of Brazil's urban population, 10.5 p.p. more than in 2Q17.

Oi shares the 4G network with other operators in order to optimize investments and reduce costs while seeking to continuously improve service quality and the customer experience. In this regard, in late February 2018, Oi entered into a Memorandum of Understanding (MOU) with TIM Participações S.A., beginning negotiations to solve old disputes and starting a new cycle of infrastructure sharing plans, in line with other current partnerships in the Brazilian telecom market. In order to meet the growing demand for data, Oi has also been focusing its efforts on improving its own 3G and 4G network capacity and coverage quality so as to

Earnings Release 3T14 allow consistent growth of data traffic in the network and equip us to achieve consistent improvements in ANATEL's network quality metrics.

Mobile ARPU

At the end of 2Q18, mobile ARPU stood at R\$ 16.1 (+4.3% y.o.y. and -1.4% q.o.q). Excluding interconnection revenues, mobile ARPU increased 3.2% over 2Q17 and fell 0.6% from 1Q18.

Net revenues in the B2B segment amounted to R\$ 1,525 million in 2Q18, 6.3% less than in 2Q17, mainly due to the decline in voice traffic and the reduction in the fixed-to-mobile (VC) and interconnection (MTR) regulated tariffs. It is important to point out that revenues fell substantially less year on year than in 1Q18 (-9.1%) and in 4Q17 (-12.9%).

The approval of the Judicial Reorganization Plan in December, 2017 gave transparency and greater clarity to the negotiation with the clients of this segment. With a more favorable business environment, it was possible to start the turnaround of the segment, based on 3 pillars: acquisition of new customers, monetization of the base and loyalty and retention.

Thereby, the B2B segment closed the quarter with 6,541 thousand RGUs, 0.6% more than in 2Q17 and in line with 1Q18, with an increase in the mobile base (+6.9% versus 2Q17 and +1.5% versus 1Q18). The segment had a net addition of 40 thousand RGUs over 2Q17 and 2 thousand RGUs over 1Q18. This shows a reversal of the downward trend for B2B revenues and base.

Corporate

In 2Q18, the Corporate segment recorded annual and sequential growth in RGUs, as well as a lower reduction in net revenues. The reversal of the downward trend was due to (i) the approval of the Judicial Reorganization Plan, which reduced uncertainty about the future of the business; (ii) the beginning of recovery in economic activity and higher demand for corporate solutions, especially IT and data solutions; (iii) the change in the segment's organizational structure this year, in order to strengthen the Company's positioning and capture synergies with the other segments; and (iv) acceleration of commercial activity, with an expansion of the

capillarity of the sales team, increasing the number of regional units from 4 to 11, in order to gain market share.

Since the approval of the Judicial Reorganization Plan in December 2017, the prospection of new revenues grew 529%, and revenues effectively contracted grew 94% in one year and 81% over 1Q18. Highlights are Data and IT services, whose new revenue growth exceeded 100% in one year.

This shows Oi's efforts to reduce its dependence on voice revenues and boost non-voice revenues, including advanced data, Internet of Things (IoT), IT (Datacenter, Oi Smart Cloud, Colocation, Hosting), Big Data & Analytics and cybersecurity solutions. In 2Q18, IT revenues grew 19.2% over 2Q17 and 3.4% over 1Q18.

As a result, in the quarter, the segment's net revenue presented a year-over-year reduction well below the levels registered in the last six quarters.

SMEs

Despite the first signs of economic recovery, with a slight reduction in the unemployment rate, the Small and Medium Enterprises segment was still affected by the adverse effects of the deterioration in Brazil's macroeconomic scenario, which contributed to the base and revenue decline.

On the other hand, the Company has been investing in service quality improvement, simplification of the offering portfolio, the broadband upselling strategy and digitalization, increasing customer loyalty and profitability while improving the customer experience.

In 2Q18, consolidated routine opex, including international operations, totaled R\$ 3,983 million, a decrease of 5.7% over 2Q17 and 2.8% over 1Q18. Routine opex in Brazilian operations totaled R\$ 3,934 million in 2Q18 (- 6.1% y.o.y. and -3.0% q.o.q.). Considering inflation (IPCA) of 4.4% in the last twelve months, this result corresponded to a decrease of 10.0% in real terms compared to 2Q17.

The Company has been reducing its costs and expenses while delivering improved productivity, efficiency in field operations and digital transformation. Operational and quality indicators continue to improve as well as the level of customer satisfaction.

Personnel

In 2Q18, personnel costs and expenses totaled R\$ 589 million, falling 2.6% from 2Q17 and 1.9% from 1Q18. In both comparisons, the result is mainly due to the maintenance of the focus on efficiency and productivity and the strict management of personnel costs.

Interconnection

Interconnection costs in Brazilian operations continued to drop in 2Q18, totaling R\$ 158 million, chiefly due to the interconnection (MTR, TU-RL and TU-RIU) tariff cuts in February 2018.

Third-party Services

Costs and expenses related to third-party services in Brazilian operations totaled R\$ 1,442 million in 2Q18, down 7.4% from 2Q17, due to the reduction in call center, selling, IT, consulting and collection service expenses. The introduction of IFRS 15, according to table 2 of this document, which came into effect on January 1, 2018, contributed to the decline of sales commission expenses by determining the deferral of incremental customer acquisition costs. The reduction in call center expenses was due to the increased efficiency of the new customer service quality model, which improved quality indicators, such as customer service costs and number of repeated costs, down 30.8% and 17.7%, respectively, year on year.

Network Maintenance Services

Earnings Release 3T14 Network maintenance service costs and expenses in Brazilian operations totaled R\$ 268 million in 2Q18 (- 19.0% y.o.y. and -2.5% q.o.q.). The decline in both comparative periods was mainly due to the lower number of incidents, thanks to preventive actions, increased productivity, higher efficiency of field operations and digitalization of processes and customer service (SO Digital). Certain quality indicators reflected this scenario, such as average waiting time for problem resolution (-21.6% y.o.y.), rework rate within 30 days (-13.3% y.o.y), average time until installation (-17.0% y.o.y), complaints to ANATEL for technical reasons (-35.7% y.o.y) and productivity (+6.1% y.o.y).

Handset Costs/Other (COGS)

In 2Q18, Handset costs in Brazilian operations reached R\$ 32 million, virtually in line with 2Q17 and lower in R\$ 5.3 million compared to the last quarter, mainly due to the lower volume of handset sales.

Marketing

Marketing expenses totaled R\$ 98 million in 2Q18, 7.8% less than in 2Q17, as a result of lower investments in the Mother's Day campaign compared with last year, and 49.9% more than in 1Q18, due to the seasonal effect created by the investments in Mother's Day campaign.

Rent and Insurance

Rent and insurance expenses in Brazilian operations totaled R\$ 1,053 million in 2Q18, practically in line with 2Q17 and 2.4% higher than 1Q18, mainly due to the contractual increase in tower and equipment rental fees, as well as EILD - industrial exploration of dedicated line - costs (basically the dollar portion), partially offset by lower right-of-way and pole rental fees, thanks to new price negotiations.

Provision for Contingencies

In 2Q18, the provision for contingencies in Brazilian operations totaled R\$ 68 million, down 26.7% from 2Q17 and down 25.6% from 1Q18. The lower level of provisions for contingencies reflects the reprocessing of the estimates model considering the new profile of payment history of tax, civil, labor contingencies, JEC and ANATEL fines, due to the new context post approval of the Judicial Reorganization Plan.

Provision for Bad Debt

The provision for bad debt came to R\$ 198 million in 2Q18, 7.0% more than in 2Q17, chiefly due to the effect of IFRS 9, according to table 2 of this document, which came into effect on January 1, 2018 and changed the criterion for provisions for bad debt. This effect was offset by the decline in default levels of retail and medium enterprise customers. In the sequential comparison, the provision for bad debt fell 2.2%, driven by a lower default level among retail customers.

In 2Q18, consolidated routine EBITDA totaled R\$ 1,563 million (-3.4% y.o.y. and -0.6% q.o.q.), while routine EBITDA from Brazilian operations totaled R\$ 1,555 million in 2Q18 (-2.8% y.o.y. and -0,7% q.o.q.), due to the combination of a 5% year-on-year decline in revenues and 6,1% year-on-year decline in costs. The routine EBITDA margin of Brazilian operations reached 28.3% in 2Q18 (+0.7p.p. and +0.5p.p.).

Non-routine items, in the amount of R\$ 156 million, refer to adjustments in provisions for contingencies, reflecting the reprocessing of the estimates model considering the new profile of payment history of tax, civil, labor contingencies, JEC and ANATEL fine , due to the new post-approval context of the Judicial Reorganization Plan.

Routine EBITDA from international operations (Africa and East Timor) totaled R\$ 7 million in the quarter, versus R\$ 5 million in 2Q17 and R\$ 16 million in 1Q18.

Earnings Release 3T14 The Company is preparing to begin a new investment cycle, which will be funded by the capital increase provided for in the judicial reorganization plan. The incremental Capex Plan will be basically focused on access, increasing high-speed broadband and mobile coverage. It will support the Company's main business transformation and growth initiatives, designed to protect the customer base, guarantee a better customer service experience through digitalization and better field operations, and increase profitability.

In order to facilitate the understanding of the impacts on financial result of novated debt accounting, the Company changed the presentation format of Table 13 above, as follows:

• (i) inclusion of "Amortization of fair value adjustment" item: according to IFRS, gain from the fair value adjustment of debt should be recorded at the initial measurement and amortized throughout the contract. Amortization is carried out on a straight-line basis and in the currency of the debt. This item shows the amortization of this gain;
• (ii) the "Net FX Result" item now includes the exchange variation of the balance of the fair value adjustment, listing all the foreign exchange impacts that affect the Company's fair value net debt. As the fair value adjustment is a reduction value of face value debt, the impact of FX variation on this adjustment is always on the opposite direction of FX variation on the debt principal, reducing the impact of foreign exchange on the Company's financial result.

In 2Q18, Oi S.A. recorded a net financial expense of R\$ 1,199 million, versus net financial income of R\$ 30,179 million in 1Q18 and a net financial expense of R\$ 4,981 in 2Q17.

The net financial income recorded in 2Q18 considers the positive impact on "Other Financial Income/Expenses" of gain from the fair value adjustment of the restructured debt, in addition to the accounting for the reversal of interest incurred in the period of Judicial Reorganization, which benefited the "Net Interest" item. The Company returned to a more normalized financial result level in 2Q18. The comparison with 1Q18 also shows three months of "amortization of fair value adjustment", versus a little more than one month in the previous quarter. This is combined with the negative impact of the 16.01% depreciation of the Real against the Dollar in 2Q18 on the portion of the new debt at fair value which is indexed to the dollar.

The year-on-year improvement in the net financial result was due to the restructured debt, which reduced interest and FX variation expenses, despite the steeper depreciation of the Real in the quarter. The financial result was also positively affected by income under "Other Financial Income / Expenses", caused by lower tax and contingency expenses, as well as higher FX income on investments abroad compared with the same period last year.

Oi S.A. ended 2Q18 with consolidated gross debt of R\$ 15,220 million, 12.5%, or R\$ 1,686 million, higher than in 1Q18 and 70.7%, or R\$ 36,710 million, lower than in 2Q17. The annual reduction was due to the conclusion of the Company's Judicial Reorganization process, when the accounting effects of the contractual conditions agreed in the Judicial Reorganization Plan began to apply.

The increase over 1Q18 was mainly caused by the 16.01% depreciation of the Real against the Dollar in the period, which had a negative impact on debt at fair value denominated in foreign currency. The accrual of interest and amortization of fair value adjustment also contribute to increasing debt every quarter.

At the end of 2Q18, debt in foreign currency accounted for 53.2% of fair value debt. The debt's consolidated average term was approximately 10 years in 2Q18.

The Company ended 2Q18 with a cash position of R\$ 5,199 million, resulting in net debt of R\$ 10,021 million, 37.1% more than in 1Q18 and 77.5% less than in 2Q17. The cash reduction was mainly due to non-recurring regulatory obligations in the quarter, such as the Fistel fee, in addition to the payment of taxes related to the debt restructuring.
