Good afternoon. Thanks for joining our conference call to review Westport Fuel Systems Q4 and yearend 2019 results. 2019 was a great year a pivotal year for Westport Fuel Systems. Each of our businesses delivered improved operating results on the topline and on the bottom line. I'm proud that in 2019, we made another big step in our transformation into a profitable and sustainable company, building on our prior year improvements with another year of double digit percentage gains. Westport Fuel Systems portfolio of clean technology solutions distributed to markets around the world and supporting our light-duty and heavy-duty OEM customers and partners is reducing the environmental impact of transportation. And our products are doing so in a cost effective way. This is critical as it enables our technologies to reach the scale required in our industry and for our environment. There have been a number of important market developments since our Q3 call, and I'll walk through these in a moment. But first I want to share the headline financial results shown in the next slide. I'm pleased and proud of our latest achievements. Continued sales growth of HPDI combined with the strength in our independent aftermarket and light-duty OEM businesses resulted in annual revenue of $305 million, up 13% over 2018 and up 33% from 2017. Net income from continuing operations increased by $41 million year-over-year, that is in 2018 we lost $40.8 million, while in 2019 we moved to the plus side earning $0.2 million. It's a big accomplishment and a very good step. We recorded our seventh consecutive quarter of positive adjusted EBITDA and we delivered our first full year of positive EBITDA. These results are evidence that our clean cost-effective market ready technologies are the answer to the increasing global demand, for sustainable transportation. For passenger cars, the light commercial vehicles, for transit buses and heavy freight haulers, Westport Fuel Systems has the products that reduce emissions, clean the air, save money and can achieve meaningful scale. Now let's review some market developments. COVID-19 has introduced historic uncertainty for all of us. Our priority is the health of our team, our partners, suppliers and customers and all of our communities that we work in around the world. We are closely tracking and monitoring the data, developments and expert recommendations around the world and doing our best to respond. While it's not possible to predict the future, we're working hard in real time to mitigate the impact of this pandemic. I'd like to recognize the commitment, dedication and responsiveness of our global team. As announced yesterday, we have suspended production at our plant in Brescia, Italy, which is near the epicenter of the outbreak in Italy. Over the last few weeks, our team at Brescia worked tirelessly to accelerate production deliveries to all our customers, while simultaneously taking all possible action to mitigate coronavirus risk in our workplace. Similarly, our operations in Cherasco and Albinea, Italy are also taking action, so far have been able to maintain production and continued delivery to our customers. The combination of the actions we've taken to secure alternative suppliers, accelerate purchase orders to increase raw material inventories and to project our team members has minimized disruptions in production and supply. Despite all our preparations, all our planning and all the actions we've taken so far and, despite our best continuing efforts to manage our operations and meet our customers demand. The implications of the pandemic and the actions being taken to respond to the pandemic are uncertain. We don't know how much market demand will be affected and if there's an adverse effect, we don't know what government actions may be taken, nor how effective those actions will be. And of course, uncertainty itself is a significant market headwind. Nonetheless, we are convinced that the longer-term prospects for our products and our company are strong. In China, while the rate of COVID-19 cases is now slowing, the combination of the initial outbreak and the mitigating measures taken by the Chinese government during the first month of this year, have delayed the timing of the certification for HPDI equipped engines. Our Weichai Westport joint venture has been working to complete the emissions testing and certification, with the Chinese Ministry of ecology and the environment, and also with the Chinese Ministry of Industry. There are many steps in the certification process including, engine dyno testing or emissions, OBD certification testing and vehicle testing with the portable emissions measurement system. Following all these tests, there are the administrative proceedings of the certifying agencies in China. We're almost done. There are no technical barriers to completion, and we look forward to sharing the accomplishment with you when we reach the finish line. While the delay compared to our plan affects the timing of the commercial launch, and the production sales growth that follows, we do not expect that it will change the shape of that adoption curve, and that the long-term potential of this product in the Chinese market, the largest natural gas commercial vehicle market in the world is quite compelling. We have a great partner, a great product and a large market to serve. In our Q3 conference call, I spoke about scale and how critical scale is in the transportation sector. Scale means production volume, sales volume and market shares that make a material difference both economically and environmentally. In transportation, scale is enabled by products that deliver what customers require, products that reduce customers total cost of ownership and products that enable OEMs to meet regulations at the lowest total cost. To scale solutions must be affordable, cost competitive, easily accessible and must meet the most stringent customer regulatory requirements in terms of engine and vehicle performance, criteria air pollutants and CO2 emissions. The next slide shows how natural gas is getting momentum in heavy-duty trucking. Until recently, the growth in Europe of natural gas fueled heavy-duty trucking has been limited by availability of products, and by refueling infrastructure. But now, with recently added products like HPDI and new CO2 regulations, we're seeing a dramatic increase in the availability of LNG in large markets like Germany, Italy, Spain and France, and as well as in smaller markets like the Netherlands, Sweden and Belgium. The LNG refueling infrastructure has grown nearly 90% in just last two years, and there are now 264 LNG stations spanning 18 European countries. The dramatic growth in the number of refueling stations is happening in parallel to the growth in a number of heavy-duty trucks. The natural gas vehicle association in Europe just released 2019 sales figures, and reports that there were more than 4500 new vehicle registrations for LNG fueled heavy-duty trucks, that's up 175% in 2018. Regulations combined with product availability, refueling availability, and winning economics are driving a real time market response. I want to remind you that Westport’s HPDI 2.0 beats the 2025 requirements to reduce CO2 emissions by 15%. And with renewable gas, and our other vehicle efficiency improvements enables OEMs to meet the 2030 mandate about 30% reduction. I'd like to flag another notable market development. On January 16 of this year, Shell announced that they will build nearly 50 LNG refueling stations in Germany. These stations will supply a blend of fossil and renewable natural gas that will make their LNG supply carbon neutral. And recent analysis demonstrates there is sufficient renewable gas feedstock to fuel the entire truck segment in the European Union. The potential to get to net zero carbon for trucking in Europe and globally, using HPDI and renewable natural gas is available now. And it can be done at a competitive total cost of ownership, compared to other technologies and with no compromise in performance, reliability or durability. In addition to HPDI for the heavy-duty market, Westport Fuel Systems have strong light-duty OEM and independent aftermarket businesses. The natural gas vehicle association in Europe estimates that the current gas vehicle fleet of 1.4 million vehicles in Europe, will grow just 13 million vehicles by 2030. That's a significant, nearly a 10 fold increase. So let's take a closer look at what happened in 2019. There were nearly 70,000 CNG passenger car registrations last year compared to 50,000 in 2017. That's a 40% growth rate over two years. Italy had 55% of these registrations followed by Germany at 11% and Spain and Sweden nearly 8% each. There are now 3700 CNG stations in Europe, that's up 10% in just one year. Italy and Germany has the largest number, and eight more European countries have more than 100 CNG stations each. It's a well-developed network. Looking to Asia, we see a strong and growing market opportunity. In China, the LNG truck market is already the largest in the world, and about 80% of the LNG trucks sold globally are sold there. Recent projections show that heavy-duty LNG trucks could approach a 20% share. Our joint venture, Weichai Westport is the leading natural gas engine supplier in China and poised to grow with the launch of HPDI 2.0. In India, the growth of CNG vehicle sales being driven by a fuel price advantage, stringent emissions regulations, proposed diesel ban and the build out of the CNG refueling infrastructure. In January of this year, the Indian government announced a plan to more than double the share of natural gas in the country's energy mix to 15% in 2030, up from 6% currently. The energy ministry also proposed a reduction in the goods and services tax on CNG vehicles. This reduction would drop the price of the CNG vehicle by more than 20%. And already compelling payback would become even more attractive, thereby driving the increased adoption of CNG vehicles. In fact, one of our customers expects natural gas vehicle sales to be greater than 30% of their future sales mix, up from 7% currently. The Indian government has plans to build 10,000 CNG stations by 2030 up from the current 1700, and LNG is also expected to gain greater market share as Total and Adani gas, recently announced their plans to build 1500 LNG stations in India over the next 10 years. Westport Fuel Systems sells products into more than 70 countries through an extensive distribution network. Our independent aftermarket business, enables conversion of the existing vehicle park to CNG or LPG, so our customers can realize fuel cost savings and also reduce emissions. The global market for LPG CNG conversion kits is approximately 1 million kits per year, and our aftermarket business has approximately a 30% share. Argentina, Italy, Poland, Russia and Turkey are well-established and critical markets for our products, markets where LPG and CNG are achieving scale. Westport Fuel Systems is well positioned to capitalize on this compelling market opportunity, the continued strength of our OEM and aftermarket businesses, the growth of HPDI in Europe and the upcoming production launch of HPDI in China are keys to our success in 2020. I'm confident that we can weather the current headwinds and continue to deliver against our 2020 strategic priorities. Let's look at those priorities. Number one, sustained growth and profitability of our aftermarket business. Number two, successful launch of HPDI in China. Third, new light-duty and heavy-duty OEM customers and fourth continued focus on material and structural cost reductions. We're pleased and proud of our 2019 results. The fundamentals that drive market demand for our products will persist and grow increasingly urgent, as we work through the new market headwinds that developed just in Q1 of this year. Now, let me turn it over to Richard to review our financials.
