Good morning, everybody. I would like to apologize for the delay. We had some technical problems, but we hope that this has now been fixed. So we would like to start with our call, Petrobras, and the results for the second quarter. This is broadcast live on the Internet and you know our site, www.petrobras.com.br/ri/english. You may follow this call in English. So www.petrobras.com.br/ri/english. And before proceeding, we may make forward-looking statements based on beliefs and assumption of Petrobras' management. The results will be both in reais and dollars in accordance with the IFRS. However, this conference call discuss Petrobras' results in reais only. I would like to give the floor to Ms. Foster now, and she will talk about the results of Petrobras, and then we will reply to the questions.
Maria Das Graças Silva Foster: Ladies and gentlemen, analysts, investors, good morning. We would like to start our presentation bringing some focus to the results of the second quarter. The highlights was the approval of the Business and Management Plan of $236.5 billion, related to projects under implementation and $27.8 billion projects under evaluation, subjected to adequate return and financeability. In June and in July, on the 23rd of June, we had a new price increase of diesel and gasoline, 10% for diesel and 8% on increase of gasoline. Also very important was in June, we booked -- domestic refining throughput record was 2.01 million barrels per day. Advances in contracting and the development of the local industry. And we had many technological problems and a new technical partner defined for Atlantico Sul shipyard and contracts for construction of 12 drilling rigs by Sete Brasil, 6 at the BrasFELS and 6 at Jurong Aracruz shipyards. And we had also the construction and integration of the first topsides of 8 FPSOs of the pre-salt and 4 foreign-built drilling rigs which will arrive in Brazil in this period. I'd also like to -- it is true that at the end of this period, in 2012, well, we have increased the number of drilling rigs. On the right, we have a picture of our deck needing conclusion of the P-55 in the Rio Grande shipyard. It was a very successful operation, showing the maturity of the shipyards in Brazil. This was an unprecedented operation, involving a structure of 17,000 tons, lifting 17,000 tons, an operation recognized as the largest operation of this nature in Brazil. Regarding the results of the second quarter 2012, Petrobras had a loss of BRL 1.3 billion in the second quarter of 2012 versus a net income of BRL 9.2 billion in the first quarter of 2012. The exchange variations influenced this. These factors are less likely to occur jointly and with the same intensity in subsequent quarters. So we would like to highlight here the exchange devaluation, which had an impact on debt and cost for our company. We also had a very significant PROEF in the second quarter. Subcommercial wells, because of exploratory activities which happened in the years from 2011 to 2012, and these activities were mainly in new exploratory frontiers. 40,000 wells were classified as dry, but most were subcommercial. We had a drop of output, and this was expected by ourselves, and they came especially from the work which we are doing regarding scheduled maintenance, particularly for recovering the Campos Basin. The greatest loss is the non-deduction. And price essential to our products sold in Brazil has also affect us, primarily 2 adjustments of price, on the 23rd of June and the 16th of June, and a significant import of LNG due to higher natural gas demand from power generation. We also had losses because of the drop of the Brent price. And here in Brazil, we work with a more expensive tax in reais. But this is some of factors led to this situation. This devaluation of the real, this started in September of 2011, and we have identified in the second quarter of 2012. And this depreciation of the real brought to us some disadvantages, particularly regarding the company's cost. For example, extraction costs and oil imports, oil products, the higher demand for fuel consumption have led us to have to increase imports. We also had a net financial income, negative of BRL 6.4 billion. And recently, we have seen in the last few weeks, at least for the last 30 days, a continued of the less -- of the drop of the real. Well, through increases of the price of fuel, oil has a positive impact in this ongoing quarter, but not -- this was not felt in the first quarter. April, May and June, there is not the full effect of the adjustments overseas price of gasoline and fuel oil. Actually, the reduction of the spreads at the end of June as I have mentioned before. We made some reduction of the production in the second quarter of 2012 when compared to the first quarter of 2012. This drop was managed by ourselves. But the drop, the effect is caused by 2 elements which in its totality were managed by ourselves. We must recover the operating efficiency, and we have to develop discipline regarding our scheduled maintenance and our stoppages. It is necessary to stop to go and do an increase of production, which will occur above all in the fourth quarter of 2012 in a very sustainable way. So we still have our targets through 2012. And additionally and a very positive way, we hope to increase our production 180,000 barrels a day. In the next few slides, you will see our numbers and the physical component of these projects. Our share of gas, and we have turned out our planning and following our initial schedule, which was June of 2012, our value right here [ph]. And we have the evaluation, which we now have. We have throughputs planned where we have 9 wells. Out of 10, we're doing 9. There'll be liftings. We will be making the connections according to our plan, gradually increasing the production of oil. Now into Bauna and Piracaba, which will come into operation in October of 2012, according to the original schedule October 2012 is being maintained. We still have some difficulties to overcome to have the whole thing ready and ready for operation, Bauna and Piracaba, FPSO Itajai and Anchieta in August and October therefore and will give us an additional 180,000 barrels a day. Extraction costs, lifting costs, we had several expenses, particularly in the recovery of operating efficiency. This was part of the business plan of the company, and we will have been very successful and very stringent in fulfilling the obligations of this plan at the profit. And we will have had -- so it is necessary to do -- what has been necessary to do, we'll have done, not only -- we have completed [ph], so totally left. So we increased exploratory activities, dry wells. We wrote-off -- well, here we have a line of 40,000 -- a write-off of 41 dry or subcommercial wells. In 2012, 16, in the first quarter of 2011, 27 wells and now in the second quarter of 2011, we are talking about 41 wells written-off. These activities in new frontiers imply lower success ratio than pre-salt's over the last few years. Higher logistic costs and consequently higher expenses related to dry/commercial wells. So 41 wells, dry wells. By type, we have 21 dry, 8 subcommercial, 9 canceled projects, 2 abandoned and 1 due to a mechanical accident. By area, 13 in post-salt, 15 onshore, 2 in pre-salt. And these 2 wells in the pre-salt don't change our rate of success. The well's operated, but otherwise last year we had 94% of success. The profile on onshore rate, this success rate was 59%. All in oil products, we had a growth of 6% in oil products in the comparison of this quarter with the same quarter of last year. We had a degree of growth due to the increase of the fleet and lower prices also of ethanol, and imports of oil products were necessary to meet the needs of volume demand in Brazil. We had real incentive of diesel -- an increase in diesel volumes. Incremental volumes were supplied by imports, especially diesel and reduced downstream margin. We had less oil to export and take or pay more national oil, and the oil results led to an improvement of refining, but we still maintained a negative trade balance. Higher thermal demand, LNG imports, our refineries have had a lot of operating efficiency and we've kept demand, we have had a generation of electric energy, thermoelectric average generation, especially in April of 5,000 megawatts. And that's really have to go from import of 700,000. An increase to import of 9 million cubic meters of LNG, and the price that we paid for it in Brazil in the second quarter was $15.45, whereas last year at same period, we had less generation and also the price, the spot market was $8.95 in the spot market. So the price has particularly drived as much. As has the international production, our production has been in line with all the events that we had the first quarter. I would like to highlight the Cascade production have ramped up in the U.S. That should be reaching a peak in September of 2012. Also, lower sales volume in Nigeria due to a lower participation in the Akpo field as a result of the termination of the recovery of the past costs. We had lower commodity prices in the second quarter of 2012, that resulted in a higher impairment of inventories, both in the U.S. and in Japan totaling a little over BRL 500 million. Then also a cost of reduction in our result due to the provision related to the agreement of the Pasadena refinery. Now I'd like to give the floor to Mr. Barbassa who will continue this presentation, giving us the financial results and highlights.
