Thanks, Andy, and welcome to our first quarter 2023 earnings call. I'd like to start by addressing the spill at our Bristol, Pennsylvania PMMA operations that occurred in late March. Let me begin by saying that our organization is deeply disappointed in this event and the disruption to our neighbors and the concerns of our stakeholders. We are working very hard to regain everyone's confidence. Due to an equipment failure, an accidental release of an estimated 8,100 gallons of acrylic latex emulsion occurred and some portion of this material was not contained at our facility, and ultimately flowed into a local waterway. We immediately reported the events and cooperated closely with local, state and federal authorities on the response activities, while at the same time, collecting material and preventing further flow into the waterway. This material is used in various downstream industrial, consumer and medical applications, including dialysis filters and is approved by the FDA for use in medical devices. Importantly, our acrylic polymer latex emulsion as a non-hazardous OSHA classification. Within that material, there are certain precursor chemicals that are potentially present. Our estimates of these chemicals dispersed within the 8,100 gallons of material and reported to the Pennsylvania Emergency Management Agency was 0.32 pounds of butyl acrylate, 1.62 pounds of ethyl acrylate, 27.22 pounds of methyl methacrylate, and 0.26 pounds of styrene. None of the water sampling conducted by authorities detected these chemicals. Due to the on-site containment and cleanup activities as part of the initial response to the release, believe that portions material never reach the waterway. Additionally, I'd like to take this opportunity to address the record about the historical environmental performance of our facility at the multi-tenant Bristol site that includes other companies' operations. Our facility has a history of compliance with environmental regulations, as indicated by the EPA's Enforcement and Compliance History Online database. Not including this event, our facility has had no significant biases, no quarters of non-compliance, and no formal enforcement actions. As you all know, we are committed to strong environmental, health and safety performance and as a company, we've had an overall outstanding EHS record. I'm proud of the response of our employees and the emergency responders to handle this in a cooperative and transparent way. Now, I'd like to turn to the first quarter results. As we entered Q1 2023 at continued low demand environment, we established three near-term priorities for Trinseo. First, to focus on working capital management to increase cash; second, to recover volumes that may have been lost to low-cost imports in Europe in the second half of last year. And lastly, we continued driving organic growth programs targeting material substitution and sustainability. I'm happy to say that our efforts around working capital management were very successful in Q1 as we reduced working capital by $52 million in the quarter. Dave will elaborate on our cash management actions in more detail, but based on the actions we are taking, we are confident we will be free cash flow positive in 2023, even at these reduced demand levels. From a market and volume standpoint, we saw a 4% increase in volume over the levels of Q4. This volume increase reflected normal seasonal improvements rather than a broad recovery in our end markets. Business conditions in the first quarter were broadly the same as what we experienced in the fourth quarter, with continued destocking and building construction, weak demand in consumer electronics, but healthier automotive demand. While our total sales volume for the company was down 20% year-over-year, volume for specialty and modified resins as well as for case applications and latex binders declined at about half that rate, which shows that these offerings have more resiliency during periods of destocking and lower structural demand. The volumes and margin for our technologies that enable our growth programs, in general, outperformed the broader portfolio and that the Q1 run rate should deliver year-over-year margin growth. The volume of products containing recycled materials, which are very high demand for our buyer customers grew at 1% and year-over-year during Q1. So far in the second quarter, April volumes are consistent with Q1, structural demand remains low, and the recovery in China has been softer than expected. While we've seen an increase in orders for some high-value specialties in China for May and June, it's too early to tell if this represents sustainable demand. Therefore, we have implemented a series of cash improvement initiatives. We've already seen the benefit of these with our strong first quarter cash generation and will continue to take action. While the timing and trajectory of the market recovery is unknown, we are addressing what we can to optimize near-term performance, while preparing for the market recovery. I'd like to comment on the results of our Engineered Materials segment in Q1. While volume and unit margins were largely as expected in almost all of our EM product lines, our MMA margins were significantly lower due to ongoing ammonia force majeure of our supplier and the impacts of the natural gas hedges against declining gas prices. These costs cannot be recovered through sales of MMA into the merchant market or through our sales of ammonium sulfate by product into the fertilizer market. However, our input costs have decreased significantly in the second quarter, as our ammonia supplier has restarted local production, and we expect to see a significantly lower natural gas hedging impact in Q2. For these reasons, we expect to see significant sequential improvement in EM results. One last comment I would like to make is related to our process to sell our Styrenics assets. We continue to have ongoing dialogue with parties interested in specific assets and regional business activities related to our Styrenics business. As we have previously stated, separating these assets is part of our long-term strategy and monetizing them is an important part of deleveraging the balance sheet. Given the continued interest in specific assets, as well as improvements we have made to them, through our restructuring actions last year, we are restarting the sales process of our Styrenics, which will include the marketing of individual assets and regional businesses. And now, I'd like to turn the call over to Dave.
