Thanks, Roger. Good morning, everyone. Thank you for joining our call. I'll keep my comments brief today so we may talk in Q&A. I'll start with a few comments regarding our first quarter that are relevant to the environment that we're in. Our operating results, as you've heard from many companies, for the first two months of the March quarter, were in line with our expectations and tracking to the expected range of $90 million to $100 million in adjusted EBITDA that we previously guided. During the last two weeks of March, patient volumes across many of our medical specialties were significantly disrupted in the early days of the COVID-19 pandemic. As a whole, this disruption in volumes reduced our revenues by roughly $40 million during those two weeks compared to our internal forecast. This impact occurred across our anesthesiology practices, across MEDNAX radiology, including our on-the-ground practices and at vRad, and within our office-based women's and children's practices, particularly pediatric cardiology and maternal-fetal medicine. Given the rapidity with which the decline of patient volumes occurred at the tail end of the quarter, we had limited ability to make adjustments in that short time frame to our expense structure, such that the impact to our adjusted EBITDA for the first quarter was more than $30 million. So most of that revenue shortfall fell straight through, and we reported adjusted EBITDA of $63 million versus our previously guided range of $90 million to $100 million. As we detailed in our press release this morning, the impact of our business persisted through April and continues today. While we have not finalized our financial results for April on a preliminary basis, our consolidated revenue declined by approximately one third. In response to this impact, we enacted a number of steps, primarily related to labor. Across our nonclinical employees, we put in place a combination of temporary salary reductions for just about everybody, ranging up to 50% reductions for our executive officers and furloughs of approximately 175 people or roughly 25% of our administrative nonclinical workforce. Within our clinical population, we worked collaboratively and in partnership with our affiliated practices to identify expense actions, including similar salary reductions, and in instances, where patient volumes had been heavily impacted, reduced hours and furloughs. It's important to note that while our revenues have been significantly impacted by COVID-related volume reductions, there simply is not a commensurate flexibility to our aggregate operating expenses, which consist predominantly of labor. As a result, we estimate that the actions we've taken would only represent a partial offset to the revenue impact we have experienced to date. To that end, we took additional steps to enhance our financial flexibility through this period. In late March, we announced an amendment to our credit facility and a concurrent drawdown of $300 million. We have also significantly reduced our third-party expenditures as part of the transformational and restructuring efforts that we've been undertaking since late 2018. Lastly, we have both received and submitted applications for monies available to us under the CARES Act. To date, the total amount that we've either received or applied for is roughly $50 million. To date, we've received $12 million of this, and we've submitted applications in recent weeks for the remaining $40 million or so that I just mentioned. This does not include a remaining tranche of money still to be distributed from the CARES Act since the mechanism to calculate those amounts is not available yet. And it also does not include the additional $75 billion being termed stimulus 3.5 for CARES 2, which is also still undefined. We also noted in our press release that we did not seek or receive accelerated Medicare payments available through the CARES Act, since it was not a material benefit for us. We also did not apply for small business loans under the Paycheck Protection Program, some of our structural elements were prohibitive to participate in that. We have, however, been able to defer the employer portion of social security payroll taxes beginning in April 2020, from which we expect to continue throughout this year as allowed under the act, another benefit to current liquidity that was available under that legislation. With that said, I'll touch on our announced sale of American Anesthesiology. Effective yesterday, this transaction was both signed and closed. We view the transaction as having four elements of value to MEDNAX. Under the terms of the transaction, we received roughly $160 million in cash and retention of net working capital, primarily accounts receivable. We also received contingent consideration in the combined NAPA organization worth up to $250 million based upon the ultimate financial return of NAPA's financial partners. Additionally, as we indicated in our 8-K filing, following this transaction, we will not incur future financial losses beginning today related to the impact of COVID-19 on American Anesthesiology's operations. It's difficult to predict what that impact would have been, but based upon multiple scenarios that we evaluated, we estimate that those losses would likely be at least in the range of $150 million to $250 million. Lastly, while I wouldn't classify this as an economic consideration, we also looked at this transaction through the scope of our remaining operating and risk profile. As Roger noted, following the transaction, we are wholly focused on our pediatrics and obstetrics and MEDNAX Radiology Solutions medical groups. In our view, this focus improves our risk profile, enables us to dedicate resources to these medical groups and pursue future growth opportunities that we believe are significant. I'd also like to provide a few thoughts that can provide some baseline views on how you can think about our company post this transaction. First, looking at our 2019 financial results. Last year, we reported total revenue of roughly $3.5 billion and adjusted EBITDA of $500 million. At the top line and as it is disclosed in our 10-K, anesthesia contributed 36% of our total revenue last year or approximately $1.2 billion. And as you might recall from my commentary over the past couple of quarters, the Anesthesia Medical group contributed roughly one fifth of our adjusted EBITDA or roughly $100 million. Obviously, given the disruption to many parts of our business, my observations do not represent a forecast of contributions from our remaining pediatrics, obstetrics and MEDNAX Radiology Solutions medical groups. In addition, as we announced in late March, we are not providing financial guidance for 2020. But I will observe that for 2019, our remaining organization that we have today contributed roughly $2.3 billion of revenue and approximately 80% of our historical adjusted EBITDA. I will also note that for the brief period when we did offer guidance for 2020, we guided toward an EBITDA number of $470 million as it compares to last year's $500 million. Second, in terms of the impact to our non-anesthesia medical groups from the COVID-19 pandemic, as we disclosed this morning, that impact was greatest within our radiology organization and in our office-based women's and children's practices. During the March quarter, the impact of these medical groups made up approximately one quarter of the total $40 million decline in revenues we experienced on a consolidated basis. Looking at our preliminary volume and revenue observations for the month, and again, let me please reemphasize this is preliminary and we are still in the process of closing our books, I will point out that the total impact to our ongoing revenues for the month was in the range of roughly 20% to 25%. Third, in the coming days, we will be filing pro forma historical financial information for the years 2017 to 2019 in order to present our past results, excluding American Anesthesiology. I will note, importantly, though, that these financials will not be a perfect representation in any respect of the past performance of our remaining medical groups since we are required that they reflect all of the overhead expenses of the company during that period, not adjusted for the sale of American Anesthesiology and the overhead and support resources that transferred with it. Looking forward as well, those overhead results will remain in our results from continuing operations. And further, we will likely retain certain operating expenses that will be necessary for the intermediate future and not associated with the transitional services agreement we have signed as part of the transaction. And finally, in terms of our balance sheet and leverage profile, given the number of moving parts, both structural and related to the uncertainty of the COVID-19 pandemic, I'm going to speak in rough terms. Prior to the onset of the pandemic and prior to our sale of American Anesthesiology, our leverage profile was essentially in the high 3s in terms of net debt to EBITDA, which was a level that we have spoken about over time as a comfortable level for this company, but with some bias to bring that down to a certain extent. As we look at the impact to our organization and our leverage profile from all of the moving parts surrounding this transaction and COVID and all of the other elements in play, again, in rough terms, I quantify that the combined impact has moved our leverage up by roughly one turn, reflecting movements to both the numerator and the denominator. That being said, we remain confident that the steps we have taken so far in response to this unprecedented time for MEDNAX, provide us with the financial flexibility we need to ensure our ability to support our clinicians and for providing them or providing them to care for their patients throughout this challenging period and beyond. With that, now I'll turn it back to Roger.
