Good morning, ladies and gentlemen. At this time, we'd like to welcome everyone to Braskem Fourth Quarter 2013 and Full Year 2013 Earnings Conference Call. Today with us, we have Carlos Fadigas, CEO; Mario Augusto Da Silva, CFO; and Roberta Varella, Head of Investor Relations. We would like to inform you that this event is being recorded. [Operator Instructions] We have simultaneous webcast that may be accessed through Braskem's IR website, www.braskem.com.br/ir. The slide presentation may be downloaded from this website. Please feel free to flip through the slides during the conference call. There will be a replay facility for this call on the website. We remind you that questions, which we will be answered during the Q&A session, may be posted in advance on their website. Before proceeding, let me mention that forward-looking statements are being made under the Safe Harbor of Securities Litigation Reform Act of 1996. Forward-looking statements are based on beliefs and assumptions of Braskem management and on information currently available to the company. They involve risks, uncertainties and assumptions because they relate to future events and, therefore, depend on circumstances that may or may not occur in the future. Investors should understand that general economic conditions, industry conditions and other operating factors could also affect the future results of Braskem and could cause results to differ materially from those expressed in such forward-looking statements. Now I will turn the conference over to Roberta Varella, Head of IR. Ms. Varella, you may begin your conference.
