Thank you, Chris, and welcome everyone to second quarter 2019 conference call. On our call today are Jeff Quinn, Chairman, Chief Executive Officer; Jean-Francois Turgeon, Chief Operating Officer; John Romano, Chief Commercial and Strategy Officer; and Tim Carlson, Chief Financial Officer. We will be using slides as we move through today's call. Those of you listening by Internet broadcast through our website should already have them. For those listening by telephone, if you haven't already done so, you can access them on our website at tronox.com. Moving to slide two. A reminder that the comments made on this call, as well as the information provided in our presentation and on our website include certain statements that are forward-looking and subject to various risks and uncertainties including, but not limited to the specific factors summarized in our SEC filings, including those under the heading entitled Risk Factors in our Annual Report on Form 10-K/A for the year ended December 31, 2018. This information represents our best judgment based on today's information. However, actual results may vary based on these risks and uncertainties. The company undertakes no obligation to update or revise any forward-looking statements. During the conference call, we will refer to certain non-U.S. GAAP financial terms that we use in the management of our business and that we believe are useful to investors evaluating the company's performance. These include EBITDA, adjusted EBITDA, adjusted EBITDA margin, adjusted earnings per diluted share and free cash flow. Reconciliations to their nearest U.S. GAAP terms are provided in our earnings release and in the appendix of the slide deck. For the company’s guidance with respect to full year 2019 adjusted EBITDA, adjusted earnings per diluted share and free cash flow, we are not able to provide without unreasonable effort the most directly comparable GAAP financial measure or a reconciliations of such GAAP financial measure, because certain items that impacts such measure are uncertain out of our control or cannot be reasonably predicted. As you saw in our earnings release, we provided our results on both a reported basis and a pro forma basis to assist in our discussion of the second quarter performance compared to the second quarter 2018 and the first quarter 2019. Our primary focus today will be on the pro forma comparisons to enhance your understanding of the underlying trends, our business performance, and in our markets. In the appendices of our earnings release and this slide deck, our pro forma statements of operations and pro forma adjusted EBITDA statements for the second quarters 2019 and 2018. Moving to slide three, it's now my pleasure to turn the call over to Jeff Quinn. Jeff?
