Thanks, Greg. I'd like to take a moment to discuss our outlook before taking questions.Turning to Slide 5, you can see our expected future RC cash flows. Based on the 20 invested facilities as of year-end and even after our normal quarterly distributions, we are reaffirming our expectation of $150 million to $175 million of after-tax cash flows to ADES through the end of 2021.As a reminder, these – this 20 facility number was updated in September of last year, due to the unexpected closure of two utilities during the third quarter sites at which Tinuum had two invested RC facilities.The reduction also included the two facilities that were placed in service in 2009, and thus, met their 10-year expiration date during the fourth quarter. Only one of these two facilities were invested and operated. And given that these expirations were also expected, they have always been included in our forward cash flow guidance.As noted earlier, we also believe that we have line of sight into adding incremental volume in 2020 and look forward to disclosing them as they occur. While we will continue to engage existing and potential tax equity partners for incremental investment in refined coal, it's important that we also plan for the refined coal cessation.We have just two years remaining for a refined coal business, with some incremental growth expected. As such, Tinuum will look to save money, while ensuring a consistently produce refined coal. Additionally, we will also respond to the quickly changing coal-fired power generation decline by reducing cash costs. We will target at least $5 million in reductions on an annualized basis, while optimizing our products and manufacturing process. We need to do both lower costs and diversify our product offerings.Turning to Slide 6, we outlined some of what we see as the key opportunities for us to maximize the potential of our activated carbon assets. As expected, but not at this velocity, coal-fired power generation continues to decline, which has forced us to turn to the adjacent market opportunities earlier than plant.We have talked about some of the non-coal industrial applications for activated carbon, we – where we have begun to gain traction with our products. These are industries that are similarly bound by regulations and the application of our products in those markets have been ahead of our initial expectations.We have also built out the internal infrastructure to better compete with the new municipal water markets. Our product portfolio and commercial strategy in these water markets is greatly improved, and we are carrying solid momentum in these markets, as we expect to see more fruitful results in 2020.Back throughout 2017 and 2018, we talk about the highly fragmented nature of the emissions control market we operated. Today, the activated carbon industry remains highly fragmented and market rationalization will be a key catalyst for growth as we expand into new markets.As this market rationalization occurs, we believe we’ll be in the best position to capitalize on emerging opportunities, given the high-quality and cost advantage characteristics of the assets we possess in this market.Flipping to Slide 7. We have added a slide to show the changing projections for the coal-fired power market in the U.S. You can see how incorrect the government agency experts have been and how quickly these expectations have fallen each forecast year. And specifically, the precipitous decline expected in 2020 from when we underwrote this asset in December 2018.This unexpected decline was the result of the convergence of four factors: One, sustained low natural gas prices; two, renewables coming to meaningful scale; three, lower overall power demand; and four, societal, governmental and business pressure against coal.While coal-fired power generation is falling faster, it is expected to remain 10% to 15% of the grid by 2030 based upon the U.S. Energy Information Administration estimate. Those remaining utilities will need long-term stable service providers that bring a full suite of emission control solutions and we expect to be that provider.The figure on the right-hand side of this slide is our internal estimates around how we intend to diversify our products away from coal-fired power generation. You can see that we made significant progress during 2019 toward diversifying our revenue stream, and we expect to continue that success in the coming quarters as we expand our capabilities.Importantly, full base activated carbon products constitute roughly 20% of the activated carbon market in the U.S., so there is ample market size and opportunity to gain additional share.As part of our focus to fill our plants capacity, we have maintained ongoing negotiations with parties that will allow us to greatly increase the current volumes and utilization rates for the assets. These discussions are fluid, but would allow us to leverage the low-cost nature of the plant. Remember, as we add volume, we can leverage our fixed cost structure, which allows approximately $0.60 of every dollar to go to our bottom line.Additionally, as I previously mentioned, as the market is changing, we will quickly adapt and will align our cash costs with our overall business to the current market dynamics. We possess the premier asset in the industry. And while 2019 got off to a rocky start, the long-term capability of these assets and the viability of the growing future market opportunities are unchanged.We expect to be a significant player in these near adjacent markets, and we are entering 2020 with a clear path to value creation because of these investments we have made and the innovations we have accomplished in 2019. We did not meet our PGI segment results, but we exceeded our refined coal expectations, even after two plant closures and poor coal-fired power dispatch.In short, our short-term 2019 results were solid because of refined coal, but in our emerging PGI segment, we need to continue to maintain share and opportunistically grow in our dynamic core market and accelerate growth into the other markets in order to claim long-term success beyond 2021.On Slide 8, we recapped the progress of our shareholder return program of our balanced capital approach. We have now returned over $100 million to shareholders since mid-2017 between our dividend program and share repurchase authorizations. In recent quarters, debt reduction has become a more critical component of this capital allocation, as we aim to pay-off the term loan balance in less than a three-year term, but we are committed to continue to distribute value for our equity holders.Finally, let's introduce our 2020 initiatives on Slide 9. Our priority is, continue to increase and protect our net RC cash flows. This priority is unchanged, as the cash flow streams continue to facilitate our capital allocation program, including the investment in our broader PGI initiatives.Our second key initiative will be to leverage our plants utilization and low-cost advantages. This will entail filling the plants volume with incremental wins in these new and growing market opportunities we spoke about, as well as remaining vigilant for additional opportunities upon the expected market rationalization, as well as reducing cash costs.And finally, we remain committed to returning capital to our shareholders, while also paying down our senior term loan and strategically investing in Carbon Solutions. Before we take questions, as it relates to COVID-19, we have not had any business interruption as a result of the situation. Obviously, conditions are changing daily, if not by the hour, and we are evaluating these changes as needed.So far, we've seen no direct personal impact to our staff or Tinuum staff, who safety will remain our number one priority. We and Tinuum are communicating with our employees, as well as business partners to place ourselves in the best preventative position possible, while also preparing contingency plans for varying degrees of potential business disruption.Tinuum is domestically-based and use many of the same chemicals as we do. Additionally, they have ample inventory stored in the U.S. We are also a domestically focused business with a highly efficient and vertically integrated supply chain.The supply stability offered by the proximity of our mine, coupled with our local distribution hub, helps us insulate us from many potential disruptions and actually offers us an opportunity to service those customers who may be seen temporary dislocations in their supply chain. [Nothing to less]. We will continue to treat this situation with the seriousness it deserves and respond to any changes as appropriate.So, with that, we'll take questions.
