Thank you, Ken. Good morning everyone. I'll start today by commenting on connection activity shown on slide seven of the presentation. Overall, we had a net loss of 31,000 retail connections in the first quarter of 2017 and ended the quarter with just over 4.9 million retail connections, about 2% higher than a year ago. In the prepaid segment, which as -- is a small part of our customer base. We had a net loss of 4,000 connections. In the postpaid segment, we had a net loss of 27,000 connections including 28,000 handsets as we didn't attract the number of new customers that we would have liked. This was due to a combination of factors that made an already competitive market even more so, factors such as lower customer switching activity, aggressive promotional activity and the reintroduction of unlimited plans. In response to the intensified market competition and the need to protect our base of postpaid customers, we launched our new total plans which include unlimited offerings in late February. As Ken said in his comments both new and existing customers responded favorably to the new plans as we saw in an improvement in our activity following the launch. For the first part of the quarter, leading up to the launch of the total plans, we have lost 35,000 postpaid connections. However, in the remaining weeks of the quarter, we added 8,000 net postpaid connections and we saw that change in momentum carry into April. As I mentioned, we lost 28,000 handset connections during the first quarter, including 9,000 smartphones. However, we continue to have customers upgrading from feature-phones and including those upgrades total smartphone connections increased by 20,000. Postpaid churn was at 1.29% this quarter, pretty flat compared to 1.28% a year ago. Handset churn was even lower as you'll see on the next slide. Handset churn for the first quarter of 2017 was 1.08%, the lowest level in many years. Connected device churn increased to 2.55% for the first quarter of 2017 due to higher tablet churn as the penny tablets sold in connection with various promotions over the past couple of years began to roll on. Let's turn to slide nine and look at revenues. As a reminder, effective January 1st of 2017, we made a change in how we're reporting imputed interest income on equipment installment plans. That income is now being reported as a component of service revenues rather than as interest income below the operating income line. This approach is consistent with that which has evolved and is now being followed by most industry participants. The numbers shown here and in all of our subsequent slides for all periods reflect the revised approach. So, let's start with service revenues, which for the first quarter of this year were $746 million, down $25 million or about 3% year-over-year. The largest component of service revenues and the main driver of the decrease is retail service revenues which at $657 million for the quarter decreased by 4% driven by lower average revenue per user. Changes in the other components of service revenues were offsetting. However, I want to say a few words about roaming. Inbound roaming revenues for the first quarter were $27 million, reflecting a sizable drop year-over-year primarily due to lower contract rates. For data, the total volume of inbound usage actually increased by 8% year-over-year. But the favorable impact of that volume increase was offset by the impact of lower rates. Over the past year, the mix of data traffic has shifted significantly from 3G to 4G, which has lower rates. I also want to remind you again that while lower data rates are putting downward pressure on revenues, at the same time, they are providing a significant benefit in the form of reduced expenses for our outbound data rolling. In the first quarter of 2017, the mitigating impact of lower rates on outbound roaming expenses was approximately three times the rate related reduction in roaming revenues. Equipment sales revenues declined 4% to $190 million, reflecting a reduction in the number of device sold along with the related impact on accessory sales. The impact of fewer unit sales was offset by an increase in the proportion of new device sales made under equipment instalment plans, and to a lesser extent, a mix shift from connected devices to smartphones. Percentage of postpaid device sales on installment plans was 80% similar to the previous quarter and up from 69% in the year ago quarter. We expect that the installment plan take rate will be higher over the course of this year given that all of our device sales to retail customers are now being done on installment plans. At the end of the first quarter, approximately 46% of our postpaid connections had an installment plan. Moving over to slide 10, which provides some additional information related to postpaid revenue. The average revenue per user, or ARPU, for the first quarter of 2017 was $45.42, down 6% year-over-year, reflecting the overall industry price competition, the continued migration to equipment installment plan pricing, and the growth in connected devices which have lower average revenue. At this point, and Ken touched on this earlier, there's very little impact related to the unlimited plans due to the timing of their launch being very late in the quarter. Given the continuing migration to equipment installment plan pricing, average billings per user, which includes installment billings provides a better representation of the total amount being collected from customers each month. As you see, this more inclusive measure is relatively flat year-over-year. The average revenue per account benefits from the increase in connections per account which grew by 3%. For the first quarter, the average revenue per account was down about 3% year-over-year. However, the average billings per account actually increased by about 3% year-over-year. So, let's move next to our profitability measures. Operating cash flow for the first quarter 2017 was $194 million, up 15% from $168 billion a year ago, notwithstanding a reduction in total operating revenues. Note the total cash expenses decreased by 7% overall year-over-year, with decreases in each major category. Some portion of the reductions can be attributed to lower sales volumes while some portion represents efficiency achieved in various areas of the business such as network operations including outbound roaming, phone replacement programs, advertising, and customer service operations. Adjusted EBITDA, shown next, incorporates the earnings from our equity method partnerships along with interest and dividend income. Adjusted EBITDA for the quarter increased of 11% to $229 million compared to $260 million a year ago. Earnings from the unconsolidated entities were $33 million this quarter including $16 million from the LA partnership. I'll also mention that in April, we received a $30 million distribution from the LA partnership. With the improvement in profitability that we achieved on lower revenues in the first quarter, operating cash flow and adjusted EBITDA as a percentage of total operating revenues both increased by approximately 330 basis points year-over-year. Cash flows from operating activities during the first quarter were $61 million, while net cash used in investing activities totaled $75 million, significant investments were made in our award-winning network, primarily for the ongoing deployment of VoLTE technology and an offer systems capabilities. At March 31st, cash and cash equivalents totaled $572 million. As Ken mentioned earlier, U.S. Cellular will be required to make a final payment of $186 million for licenses acquired in the 600 megahertz option. We plan to make that payment later this month using cash currently on hand. In addition to the existing cash balance, U.S. Cellular has $298 million of unused borrowing capacity under its revolving credit facility. We believe that these resources together are sufficient to meet our operating investment and debt service requirements for the remainder of this year. You'll note that we disclosed in the Form 10-Q report filed today that U.S. Cellular has created a special purpose entity designed to facilitate a potential financing by monetizing an accounts receivable related to equipment installment plans. This provides an attractive and flexible financing vehicle that we could use in the future. Next, I want to cover our guidance for the full year 2017, which is shown on slide 13 of the presentation. For comparison, we're showing our 2016 results, which have been recast to reflect the change in the classification of imputed interest income on equipment installment plans effective January 1st of this year, along with our previous and revised estimates for the current year. So, first, for total operating revenues, our estimate of the $3.8 billion to $4 billion is unchanged. Our operating cash flow, our revised estimate is a range of $550 million to $650 million. The revised estimate raises the guidance by incorporating an increase of $50 million to the bottom end of the range to reflect the strong profitability that we're reporting for the first quarter. The change at the bottom of the -- bottom end of the range for operating cash flow also impacts the estimate for adjusted EBITDA, which is now $700 million to $800 million. Although we're making these changes to our guidance to reflect our first quarter results, we believe that the competitive environment and related factors remain very unsettled. For example, the overall pricing and promotion environment, the degree of customer migration to the new total plants and the related impacts on ARPU and network costs customer phone upgrade activity, these among others. Obviously, how these factors play out over the rest of the year could impact our actual results and where they fall in the ranges. Our capital expenditures, our guidance is unchanged at approximately $500 million, including spending associated with the continued deployment of VoLTE technology. As Ken said earlier, the impact of the unlimited plans on network usage is something that we need to watch over the longer term. However, given the manner in which we build and operate our network to ensure a great experience for our customers, we believe that the current capacity plan will efficiently handle any uptick in usage this year. And the capital expenditures will be within the guidance that we're confirming today. So, now I'll turn the call over to Vicki Villacrez to discuss TDS Telecomm. Vicki?
