Okay. Good morning, everybody, and thank you for participating at this conference call, once more, to discuss our results. We have today a 5-slide presentation to discuss the main events of the period. And after that, as mentioned, we will go to our question-and-answer session. Let's move then to Slide 3. I'll talk about our -- the company's billed water and sewage volume that came up 2% on the first quarter to over first quarter 2012. This increase in billed volume was due to the increase of 2.7% in water connections and 3.5% in sewage connections. This is in line with expected growth of approximately 2.5% in billed water volume and between 3% and 3.5% in billed sewage volume the latter influenced by the company's large investments in this segment. The water loss ratio remained flat, closing the quarter at 25.5%. But we -- again, you would like to remember that last year, the company signed a very unprecedented loan agreement with JICA, the Japanese official bank, totaling at BRL 710 million to finance our corporate water loss reduction program. I believe we mentioned this before. I'd just like to highlight that we are expecting that the initiatives of this first stage of the program should take -- start to take effect in the beginning of the second half of 2013 this year, as we are in the process of -- final process of bidding and hiring the work services. After that, we definitely should keep track and expect reductions in our water loss ratio. Let's move now to financial highlights or Slide 4. Here, we see that the net operating revenue was positively affected by the 2% upturn in total billed volume and the 5.15% tariff increase as of September 2012. Cost and expenses fell by 2.4% in the…

[Operator Instructions] Our first question is Hasan Doza from Water Asset.

I just have a quick question on the last point you mentioned, which is this request for postponement -- a 12-month postponement. Can you just explain that a little bit as to what tariff you're referring to on this 12-month postponement, please?

Yes. Just to be very clear, Hasan, if you look at the tariff schedule, we have, as part of the process, also to review the tariff structure. That is how we charge people in different categories and the costs for them according to their consumption. So we had to present, by April 30, submit to them our tariff structure proposal, and that would all go into the same discussions around the final average tariff. So what we asked for a postponement is only specifically and only the tariff structure proposal -- sorry, the tariff structure discussion. So all the rest is still undergoing. We have not filed any request for any other postponement other than this additional matter that would have been put into the entire environment for discussions we're in right now. Hopefully -- I hope this clarifies.

[Operator Instructions] It appears to be no further questions. Now I'll turn the conference back to SABESP for their final remarks.

Well, thank you, everybody. We will still, today, put it in our website, but now first in Portuguese, working hard on English, our request that we have just announced so you can be more specific and understanding of what we have made public right now. Okay? Thank you and talk to you in a quarter or this afternoon as we have the Portuguese call and investor event here. Goodbye.
