Rodrigo Maia Good afternoon, everyone. I'm Rodrigo Maia, Investor Relations of Gerdau. Welcome to Gerdau's First Quarter Earnings Results in the first time using video conference platform. Here today is Gustavo Werneck, Chief Executive Officer of Gerdau; Harley Scardoelli, Chief Financial Officer who will present to you today. All analysts and investors can send their questions to the chat. And then the questions will be answered by both Gustavo and Scardoelli after the presentation. I would like to clarify that any information forward-looking statements that might be made during this conference call related to Gerdau's business outlook, projections and financial and operating goals are mere assumptions based on the management's expectations related to the future of the company. Even though Gerdau's believes that its comments are based on reasonable assumptions, there is no guarantee that future events will not affect this evaluation.
