Thank you, Dan, and thank you to everyone on the call today. When I joined the Company four years ago, we knew that the road ahead would not be easy. First, we would have to ride out a vastly oversupplied enrichment market with prices in freecall. Second, all of our competitors were state-owned enterprises with a political and financial backing to show for it. Achieving our goals to resume production of enriched uranium and return to profitability would take years of hard work and require making some tough choices. We would have to get smaller before we could get bigger. To weather these challenges and to set ourselves up to capitalize on the market, ultimately we took a number of steps. We cut our overhead by 16% from its peak in 2016, and restructured and reduced our debt by 59%. We hustled to bring in $100's million in new sales. We adapted to the challenges posed during eight years of falling prices by locking in low cost supply for the long-term, and by diversifying into new business lines that laid a broader and stronger foundation to build our Company. As we continue to execute this game plan, we met all our guidance for 2018 with $193 million in total revenue, $164.4 million in separative work units and uranium revenue, and a cash balance of $123.1 million at year-end. At the same time, we've always known that there would be some difficult years, and 2018 was one of them. A greater proportion of our sale in 2018 were made under newer contracts signed when market prices had fallen substantially from earlier levels, both because of the natural evolution of our order book, and because of the specific deliveries made during the year. On the other hand, our cost of sales in 2018 was still based in part on legacy prices that predated the fall. That unfortunate combination will change in 2019 as I will describe in a moment. But for 2018, the result of that combination was $104 million loss. Taking account of the difficulties of weathering the challenges of falling market, the other part of the game plan from the beginning has been to be very careful of strategic in managing our cash to get through this period and to position the company to succeed in the long-term. We finished the year still in a good position with $123.1 million in cash, at the top end of our guidance, which ranged from $100 million to $125 million. We expect to generate sufficient cash from operations in 2019 to pay the PIK toggle notes due in September, which had a balance of $26.7 million at December 31, and still end 2019 with a cash balance in the range of $120 million to $140 million. We also ended the year with an order book in our LEU segment valued at $1 billion. That includes a number of new sales contracts signed in 2018 as we extended our order book to 2030. As we close the books on 2018, there are some important changes coming in 2019 that will improve our results this year and will enable us to return to profitability in 2020. Marian will go through the numbers in greater detail, but the big driver in our loss last year, as I mentioned earlier, was the decline in our average sales price. Starting in 2019, however, we expect our cost of sales to be significantly reduced. When we signed our supply contract with TENEX in 2011, market prices were still near their all-time high. But the contract contained a price reset provision that took effect at the beginning of this year based on recent prices, which were historically low. Because of this reset, the price we will pay in 2019 and for the duration of the contract will be more closely aligned with recent market prices. While it will take time for these savings to be fully reflected in our reported cost of sales, they will reduce our cash costs as we obtain supply and will begin to show up at our earnings towards the end of 2019, and then more prevalently in future years. Based on our current projections, we expect a return to profitability in 2020. This is all occurring as the dramatic price declines for enrichment we've seen since 2011 have finally halted and begun to rebound. In September, the published spot price indicator for enrichment picked up for the first time since 2010, back in November 2010. The spot indicator has now increased by 26% since August, and published forecasts call for continued increases. Many utilities postponed their long-term contracting while the market was still falling. But now that prices are rising and supply is tightening, we expect to see an increase in contracting activities in the 2020s. We are actively pursuing new sales with existing and potential customers around the world. The other major development is that in 2018, we signed a long-term supply agreement with Orano, the French Government's uranium enrichment company. We now have access to more than 6 million separative work units from Orano through 2030, which is the equivalent to more than 50 reactor years of nuclear fuel. That, in addition to our TENEX contract and our producers of stranded material on the open market, has strengthened our position as the world's most diversified supplier of nuclear fuel and strengthens our ability to compete effectively as the market recovers. We've also begun to turn the corner in our contract services segment, where we secured several contracts in 2018, delivering on our plan to diversify into new lines of business. I would like to highlight our work for X-energy to design and to help license a first of the kind fabrication facility for next generation nuclear fuel that can power many of the advanced reactors under development around the world. This fuel could also be used in existing reactor to take advantage of the accident tolerant fuels being developed by several firms right now. In either market, the X-energy TRISO fuel particle has the potential to be the preferred option for fueling the reactors of the future. As the advanced reactor market matures in the coming years, we are well positioned to provide engineering design and manufacturing services to the companies designing the next generation of reactors, including through the Memorandum of Understanding we signed with Doosan Heavy Industries in September. In January, the U.S. Department of Energy announced its intent to deploy a cascade of AC-100M centrifuges at our facility in Piketon, Ohio. The cascade would demonstrate the technology’s capability to produce high-assay, low-enriched uranium, which is a new form of commercial enriched uranium that will be needed to fuel many of the advanced reactors now under development. This work would dovetail our X-energy work, providing some of the first concrete steps to deploy a U.S. fuel cycle to support the next generation of reactors. While we still need to work out a contract with the Department of Energy, and nothing is guaranteed at this point, we are ready to move ahead quickly once the contract is in place. This high-assay low-enriched uranium project builds on the successful work of our centrifuge technology team in Oak Ridge, Tennessee, which last September completed the most recent contract with Oak Ridge National Laboratory to continue development and testing on the AC100 design. The team has spent the past three years improving the design for reliability, costs, and manufacturability, and the new Piketon cascade will demonstrate those improvements. We are continuing our discussions with the Oak Ridge National Laboratory about a follow-on contract in Oak Ridge to ensure that the United States has a robust centrifuge testing and analysis capability in the future. Based on our track record of performing decontamination and decommissioning services at our old facilities, and at the Department of Energy site in Ohio, we were awarded a $15 million work authorization for the D&D of the K-1600 centrifuge test facility in Oak Ridge. We have been awarded additional D&D work at another facility on the Oak Ridge reservation and are pursuing additional opportunities where we can bring our experience and expertise to bear in solving complex engineering problems and manufacturing to state-of-the-art levels of precision. We've been awarded a number of other smaller contracts that tap into our advanced engineering design and manufacturing capabilities at our Technology and Manufacturing Center in Oak Ridge, and which could serve as an entree into new areas of work and larger contracts in the future. All of this was driven by our technology team and the capabilities we had assembled for the centrifuge program, which has a wide range of applications for advance engineering and manufacturing in energy, defense and other industries. So we are optimistic about the prospects to grow this part of our business in the years ahead. And now for more details on the quarter's financial results, I will turn the call over to Marian.
