Thank you, Edvaldo, and thank you everyone for joining us on the call today. Before we begin, I would like to remind everyone that this conference call may contain predictions, estimates and other forward-looking statements regarding future events or future performance of Quest.

Such forward-looking statements are based on Quest's current expectations, estimates, projections, beliefs and assumptions and involve significant risks and uncertainties.Actual events or Quest's results could differ materially from those discussed in the forward-looking statements as a result of various factors, including changing market trends, reducing demand and the competitive nature of Quest's industries, discussed in greater detail on Quest's securities and filings with the Securities and Exchange Commission, including its report on Form 10-K for the year ended December 31, 2018.
