Thanks, Ken and good morning everyone. Let me touch briefly on postpaid connections results during the first quarter shown on slide 11. Postpaid handset gross additions were down due to two factors. Early in the quarter, we pulled back on promotional activity to focus on brand initiatives. And as we moved back to a more competitive posture, store traffic dropped due to the impacts of COVID-19. Partially offsetting this was a jump in demand for connected devices. Total smartphone connections increased by 4,000 during the quarter and by 63,000 over the course of the past 12 months. That helps to drive more service revenue given that ARPU for a smartphone is about $21 more than ARPU for a feature phone. As mentioned, we saw a 7,000 increase in connected device gross additions year-over-year. This was driven by March gross additions of Internet products such as hotspots and routers, as a result of an increase in demand by consumers, as well as our business and government customers. Both customer groups were seeking wireless products to meet their needs for remote connectivity resulting from the stay at home orders from various states in response to COVID-19. In April, we saw about a 50% decline in-store traffic, negatively impacting gross additions, equipment sales and accessory margin. Although connected device activity remains stronger than prior year, we expect gross additions to trend below prior year levels through the duration of the COVID-19 crisis and perhaps beyond. Next I want to comment on the postpaid churn rate shown on slide 12. Postpaid handset churn depicted by the blue bars was 0.95% for the first quarter of 2020. We saw higher handset churn in January and February as compared to prior year, primarily as a result of aggressive industry-wide competition. However, we saw a decrease in defections in March as customer shopping behaviors were altered due to the overall COVID-19 crisis and related stay at home orders. Total postpaid churn combining handsets and connected devices was 1.21% for the first quarter of 2020, also lower than a year ago. Currently, as you would expect, churn on both handsets and connected devices is running at very low levels. April looks like it will follow that trend with both voluntary churn and involuntary churn trending lower than pre COVID-19 crisis levels. Keep in mind, involuntary churn is depressed as customers that have signed up for the FCC pledge are not being disconnected for non pay. Now, let's turn to the financial results on slide 13. Total operating revenues for the first quarter were $963 million, a decrease of $3 million year-over-year, while service revenue increased $21 million. Retail service revenues increased by $12 million to $671 million. The increase was due largely to higher average revenue per user, which I'll cover on the next slide. As part of caring for our customers during the COVID-19 crisis beginning in March, we elected to waive overage charges and we also waived late fees and other fees in conjunction with the FCC pledge. Inbound roaming revenue was $37 million. That was an increase of 10% or $3 million year-over-year, driven by higher data volume partially offset by lower rates. Since late March, we have seen a decline in data traffic both from an inbound as well as an outbound perspective. This trend has continued on into April. The extent to which roaming traffic will be impacted in the future will depend upon the duration and pervasiveness of stay at home orders, as well as customer behavior in response to the outbreak. Other service revenues were $54 million that was an increase of $6 million year-over-year, including an increase in tower rental revenues. Finally, equipment sales revenues decreased by $24 million or about 10% year-over-year due to changes in the average selling price and mix of devices sold. Going forward for the rest of the year, equipment revenues are expected to trend in line with gross additions and upgrades. Now, a few more comments about postpaid revenue shown on slide 14. Average revenue per user or connection was $47.23 for the first quarter up $1.79 or approximately 4% year-over-year. On a per account basis, average revenue grew by $4.08 or 3% year-over-year. The increase was driven by several factors, including a higher mix of smartphones relative to connected devices, an increase in regulatory recovery revenues and increased device protection revenues. Let's move next to our profitability measures on slide 15. First, I want to comment on adjusted operating income before depreciation, amortization and accretion and gains and losses. To keep things simple, I'll refer to this measure as adjusted operating income. As shown at the bottom of the slide, adjusted operating income was $231 million flat year-over-year. As I commented earlier, total operating revenues were $963 million, a decrease of $3 million year-over-year. Total cash expenses were $732 million, decreasing $3 million year-over-year. Total system operations expense increased year-over-year. Excluding roaming expense system operations expense increased by 6%, mainly driven by increases in cell site rent expense and maintenance expense, while total data usage on our network increased by 59%. Roaming expense decreased 13% year-over-year, due to lower rates, partially offset by a 55% increase in off-net data usage. As I said earlier, outbound roaming has been and is expected to be lower as roaming activity has decreased in relation to stay at home orders. Cost of equipment sold decreased 7% year-over-year. We also expect cost of equipment sold to trend in line with gross additions and upgrade levels. Selling, general and administrative expenses increased 3% year-over-year, driven by an increase in bad debt expense of $9 million, primarily as a result of U.S. Cellular's participation in the FCC pledge to not terminate service, due to customers' inability to pay. As a result of our participation in the pledge, we expect to have further negative impacts to our financial results including bad debt expense. Moving to slide 16. Shown next is adjusted EBITDA, which starts with adjusted operating income and incorporates the earnings from our equity method investments along with interest and dividend income. Adjusted EBITDA for the first quarter was $281 million flat year-over-year. Earnings of unconsolidated entities increased by $1 million or 3%, while interest income decreased by $2 million, due to a decrease in the average amount invested for the quarter as well as lower interest rates. Adjusted operating income and adjusted EBITDA do not include depreciation, amortization and accretion expense. In connection with the network modernization and 5G initiatives, we are upgrading several of the network equipment elements. This results in the recognition of accelerated depreciation on certain of the assets being replaced. As a result, depreciation, amortization and accretion expense was up 5% from a year ago. Our final slide, Slide 17 provides our updated guidance for the year. As we have highlighted throughout the call, there is a good deal of uncertainty related to potential business outcomes for the year. Given the timing of the COVID-19 outbreak and the manifestation of its impacts having only begun to take effect in mid- to late March, we essentially have less than one month of data to consider as we think about the likely outcomes for the year. However in that time we have seen limited impacts on revenue. On the cost side we have seen more impact, although still modest, driven primarily by the FCC pledge and the associated incremental bad debt expense as previously discussed. These outcomes in our consideration of other potential impacts on the business including those related to customer sales activity roaming and other operational costs to care for associates and customers have informed the guidance we are providing today. I want to take a moment to remind everyone that our guidance is on service revenues not total operating revenues, which includes both service revenues and equipment sales. Variations in equipment sales typically have a corresponding impact on cost of equipment sold and as a result are less impactful to our profitability measures. Therefore we believe that service revenues are the more meaningful revenue measure for guidance purposes. For total service revenues, we have maintained our range of approximately $3.0 billion to $3.1 billion. We have lowered our adjusted operating income and adjusted EBITDA ranges by $50 million each to $725 million to $850 million and $900 million to $1.025 billion, respectively. For capital expenditures, we are maintaining our guidance range of $850 million to $950 million. As Ken noted in his opening remarks, at this point we continue to make good progress on our key projects, such as VoLTE deployments, 4G LTE network modernization in 5G and do not currently anticipate any major disruption to any of them. I will now turn the call over to Vicki Villacrez. Vicki?
