Thank you, Kevin and good morning everyone. Despite a challenging and highly uncertain economic environment due to the Covid-19 global pandemic, AMETEK delivered solid first quarter results, highlighted by excellent operating performance with earnings in line with our guidance range. I'll provide more details on the first quarter results shortly, but first I want to extend my thanks to all my AMETEK colleagues and recognize them for their amazing dedication and commitment through this difficult time. A courage and resilience I witnessed has been truly impressive. As AMETEK has been deemed an essential or life sustaining business at our operating facilities, our employees continue to provide critical solutions and services to customers across many industries including healthcare, defense, food and beverage and laboratory research. To help safety and well-being our employee as they support these essential customers is our highest priority. We've implemented numerous safety measures aimed at providing a safe work environment. Our pandemic response plan providing a framework for our businesses to manage our facilities and workforce during this pandemic. Among other things the plan to establishes personal and workplace hygiene practices, a global communications network of site and country pandemic coordinators, and a supply chain logistics and operations team to provide solutions to help mitigate the impact of pandemic on our business. Daily communication with local pandemic coordinators and senior management ensures we are complying with the center of disease control and local government regulations. As part of the plan, we also implemented various safety measures including work from home requirements for those whose job allow, social distancing on our facilities and our factory floors, daily temperature monitoring of employees reporting work, use of personal protective equipment and staggered work shifts. We remain vigilant as we return to higher level of operating activity. Now let me return to the first quarter results. First quarter sales were $1.2 billion, down 6.6% from the same quarter in 2019. Recent acquisitions contributed 4%; the divesture of Reading Alloys was a two point headwind, foreign currency was one point headwind and organic sales were down 8% in the quarter. The measures we took during the quarter led to strong operating performance. While operating income decreased 3% year-over-year to $276 million. Operating margins expanded an excellent 100 basis points to 23%. Excluding the dilutive impact of acquisitions, operating income margins expanded 110 basis points over the prior year period. Detrimental margins in the quarter were approximately 10 % shut our operating capability reflecting our ability to reduce our cost structure, as well as the strength and flexibility of our operating model. Adjusted EBITDA in the quarter was $342 million, up 2% over the prior year with a record adjusted EBITDA mortgages of 28.5%. The operating performance led to earnings of $1.02 per diluted share, up 2% versus the comparable basis in the first quarter of 2019. And in line with our guidance range of $1.01 to $1.04. The $44 million restructuring charge we took in the quarter is expected to generate approximately $85 million in annualized structural savings. We also generate a strong cash flow in the first quarter with operating cash flow up 38% to $271 million. Free cash flow conversion was also strong at 148% of adjusted net income excluding the Reading Alloys gain. Next, I will provide additional details at the operating group level. Sales for our Electronic Instruments Group were $774.2 million, down 4% over last year's first quarter. The acquisitions of Gatan and IntelliPower contributed 6%. Foreign currency was a modest headwind and organic sales were down 9%. EIG's operating income in the first quarter was $194.1 million, down 4% versus the prior year. EIG operating margins were 25.1% in the quarter. Excluding the dilutive impact of acquisitions, operating margins expanded 20 basis points over the prior year period. The Electromechanical Group also delivered strong operating performance in the quarter despite top-line weakness as a result of the coronavirus. EMG's first quarter sales were $428 million, down 11% versus the prior year. The acquisition of PDT added 3% of the divesture of Reading Alloys was a six point headwind. Foreign currency was a one-point headwind and organic sales were down 7%. EMG's proactive cost mitigation actions led to impressive margin expansion. Our operating income was down slightly to $97.5 million in the quarter, operating margins excluding acquisitions expanded 220 basis points to a record 22.8%. During the first quarter, we also completed the acquisition of IntelliPower, a leading provider of high reliability, ruggedized uninterruptible power systems for mission-critical defense and industrial applications. Their products and solutions nicely complement our power systems and instruments businesses and they deepen our expertise and high reliability power protection applications. Annual sales for IntelliPower were approximately $40 million and we deployed $150 million on the acquisition. We also completed the divesture Reading Alloys to Kymera for $250 million. The closing of the transaction which occurred near the end of the first quarter was a positive outcome for all parties as Kymera is an outstanding strategic partner for Reading Alloys. For AMETEK, proceeds from the sales were reported on our acquisition strategy which remains our priority for capital deployment. While we are pleased with the first quarter results, the global economic environment is obviously changed since the start of the first quarter. In January, global demand was solid. In February and extended Lunar New Year holiday due to the coronavirus resulted in disruptions and China-based activity for customers and suppliers. Later in the month as China slowly reopened for business, Europe and the US and other parts of Asia started to feel the impact of the virus. At that time, we started to limit discretionary spend and non-essential travel. In addition, each of our businesses develop detailed contingency plan to prepare for a potential slowdown. In March, the impact of Covid-19 on the global economy was broadening. Many countries, states and counties started to impose travel restrictions, stay at home orders and social distancing measures for all but essential employees. Supply change delays started to emerge and customers turn cautious given the building uncertainty. Although, our facilities were operational throughout the first quarter given our essential business designation, we did see a direct impact on sales in the first quarter due to the virus. Worldwide travel restrictions limited our ability to provide support and installation services. This impacted our EIG process and power businesses most significantly in the quarter. And a broad set of customers delayed shipments. Now a few comments on the demand environment in April. Demand in April was meaningly weaker than we experienced in March. Travel restrictions and social distancing mandates shut down all but essential activities as customers and suppliers temporary closed or implemented furloughs for all or parts of April. This has inevitably led to significant disruptions and impacts on demand. Restrictions across many geographies are slowly being loosened. However, we remain cautious on the pace of recovery. Now let me provide some comments on what we were seeing in select end markets. Although, we're seeing challenging conditions across most end markets, we're seeing solid demand continue across our healthcare, medical and defense markets, which account for approximately 20% of our sales. Our most challenged markets are commercial aerospace and oil and gas which combined account for approximately 16% of AMETEK sales. We expect meaningful weakness across these markets throughout all of 2020. In the balance of our markets including power, industrial, semiconductor research, metals and automations, we expect weak conditions in the second quarter with sequential improvements during the second half of the year. Shifting now to the actions we are taking to proactively manage our business, while ensuring we are supplying and supporting our key customers. As the spread of the virus expanded and restrictions widened in March, our business began to execute on contingency plans and implemented cost reduction actions. These contingency plans focused on maximizing cash flow, ensuring critical sources of supply and protecting key investments. All while ensuring appropriate safety measures were in place. The cost reduction actions we are taking include structural actions such as reduction enforce and facility cost consolidations, as well as temporary reductions, such as discretionary spend reductions, furloughs, temporary facility shutdowns; short time work weeks and temporary pay reductions. Given the reduction in demand we are experienced and we made a difficult decision to reduce our workforce. The total reduction of forces approximately 10% of our employee base across direct, indirect and SG&A functions. In addition, in the second quarter many of our businesses are implementing furloughs or temporary facility shutdowns. These furloughs generally range in length from one week to three weeks depending on the operating location and their customer market dynamics. The decision to furlough operations was made to have mitigated the spread of the virus, to better align our cost structure with demand and to position us to quickly respond when demand returns. The temporary pay reductions we implemented generally range between 15% and 20% for salaried employees including all AMETEK officers with a similar reduction of fees paid to our Board of Directors. As a result of these actions, we expect total cost savings in the second quarter of approximately $80 million with approximately $50 million of these savings from temporary actions and $30 million from structural actions. As we proceed into the second half of the year, we expect the benefit from our structural cost actions to ramp up with full year structural savings started at approximately $125 million. We will flex our temporary cost savings either up or down in the third and fourth quarters based on volume levels. In addition to these cost savings initiatives, we also reduced our capital expenditures by over 25% from our initial plans in the year, with full year CapEx now expected to be roughly $75 million. Before I provide commentary on our outlook for the quarter, I want to highlight the work AMETEK is doing where we operate to assist in the fight against Covid-19. Through the Ametek Foundation, we have made more than $1.5 million in contributions to charitable organizations many of whom are providing food and essential items to those in need, along with personal protective equipment to the men and women on the frontlines of this pandemic. We are proud to partner with numerous organizations around the world where we have an operating presence to support the immense humanitarian crisis caused by the pandemic. I also wanted to highlight a few of Ametek businesses are involved in the fight against Covid-19. AMETEK Roland, a leading provider of mission-critical communication and workflow solutions used in hospitals and other healthcare facilities has developed the Roland Rapid Response kit. This solution allows nurses and healthcare providers to quickly triage patients, gather necessary supplies and determine the appropriate clinical response all while keeping a safe distance to minimize repetitive staff to patient contact. They are being deployed for use in temporary medical facilities and new patient care facilities within hospitals to meet the surge of additional patients. Ametek Land is another great example. Land is a leading manufacturer of monitors and analyzers for industrial infrared, non-contact temperature measurement. In March, they released their virulence solution, a temperature screening thermal imaging system designed for highly accurate human body temperature measurement. This technology can be utilized for screening at point of entry into key facilities such as offices, factories, schools, government buildings and transportation hubs. They are seeing strong initial interest for the solution is temperature screening at this scale will play a fundamental role in helping to contain the spread of the Covid-19 and along with return to our normal daily lives. AMETEK's Powervar business is providing customized, uninterruptible power systems to a number of leading medical device diagnostic equipment providers' use for coronavirus testing. These UPS systems are being deployed worldwide. And lastly, AMETEK Advanced Motion Solutions is providing critical solutions to manufacturers of ventilators and laboratory diagnostic equipment used in the Covid-19 response. These are just a few examples of the critical roles our businesses are playing and combating this global crisis. We are proud to be part of the solution and committed to supporting our customers in these efforts. As we previously announced due to the uncertainty is presented by the Covid-19 global pandemic, we have withdrawn our full-year guidance and will not be issuing quarterly guidance at this time. We will issue guidance as condition stabilizes and visibility improves. However, I did want to provide some level of comments about the second quarter and the balance of the year, given what we know now. First, we expect that the quarter will be the low point in sales in earnings this year given broad-based uncertainty and the impact on global demand from stay-at-home orders and travel restrictions. Second, we expect sequential improvements in sales and earnings in the third and fourth quarters as the economy slowly reopens. And third, we expect to manage full-year decremental margins in the 25% to 30% range. While the second quarter decremental is being between 30% and 35%. To summarize, AMETEK delivered solid results on the first quarter on strong execution through unprecedented market dynamics. Bill will speak to this in a moment, but the actions we took in the first quarter strengthen our already strong balance sheet and liquidity. And we are poised to emerge from this economic crisis in a strong financial position, which will allow us to continue to deploy capital and acquisitions and invest in our growth initiatives. We are confident in the future of AMETEK as our world-class talent and the adaptability of the AMETEK growth model will continue to drive long-term sustainable success for our stakeholders. The message we've given to our employees is simply, while these are truly unprecedented times, AMETEK has faced challenging and uncertain environments before. And each time the collective strengths and talents of all AMETEK colleagues have allowed us to emerge stronger and better position. Together, we're working to make sure AMETEK again emerge stronger and better position for the next chapter of our growth. I will now turn it over to Bill Burke who will cover some of the financial details of the quarter then we'll be glad to take your questions. Bill?
