Thanks, Mike, and hello, everyone, and thanks for being on the call today. Let me begin with our financial summary, which is on Slide 5. I think most of you know the FASB has been very, very busy this past year implementing a number of accounting standards, five of which have direct impact on AT&T. Those include standards that deal with revenue recognition, pension reporting, impacts on cash flow reporting. These changes impact our income statements and cash flow. At the same time, the company made a policy decision to record universal service fees net as an offset to our regulatory fees. We're working hard to help you understand these changes. So in addition to the GAAP financial information, we're providing comparable historical results to help you better understand the impact on the financials from revenue recognition and the policy decisions, as well as Time Warner's second quarter results on a historical basis. We will be referring to these historical results in our comparisons during the call. Now let's start with EPS. We continue to show strong adjusted EPS growth, up more than 15% for both the quarter and year-to-date. Tax reform continues to have a positive impact on EPS as does the adoption of revenue recognition. We also had about $0.02 of help from the 16 days we own Time Warner, which we have renamed WarnerMedia. The WarnerMedia earnings contribution was slightly more than what you might expect for such a short period. But as you know, financial results can be uneven, and we saw that in the second quarter. Consolidated revenue came in at $39 billion, down slightly from a year ago, but that includes about $900 million of pressure from how we are now accounting for USF fees on a net basis. When you look on a comparable basis, revenues were up slightly, thanks mostly due to the two weeks of Time Warner revenue but also helped by gains in wireless and AdWorks. We continue to use our tax reform savings to invest in and grow our customer base. As John Donovan will discuss, these investments help drive post-paid phone growth and significant year-over-year improvement in prepaid phone net adds, continued growth in consumer broadband customers even in a seasonally challenging quarter and solid subscriber growth in total video customers. Adjusted consolidated operating margins in the quarter were up year-over-year on a reported basis but down on a comparable one. Solid smartphone sales drove some of the pressure to margins, but the biggest factor continues to be customer transition to over-the-top video. Let's now look at free cash flow. It was a strong $5.1 billion for the quarter, up substantially both year-over-year and sequentially. Year-to-date, our cash from operations and free cash flow is up about $1.5 billion, which makes us very comfortable with our free cash flow guidance for the full year. Our cash flows also reflect the timing differences between spending for FirstNet and the reimbursements we received from the organization. This usually trail spending by several months. Year-to-date, that comes to more than $100 million of free cash flow pressure. Capital spending for the quarter was $5.1 billion or $5.4 billion before the $300 million of FirstNet reimbursements we did receive in the quarter. Let's now cover financial results from operations beginning on Slide 6. AT&T's domestic mobility operations are divided between the Business Solutions and consumer wireless segments. For comparison purposes, we're providing supplemental information for our total U.S. wireless operations. Our wireless business turned in very good results. Year-over-year service revenue turned positive. Margins remained strong, and we had phone growth in both post-paid and pre-paid. Total revenues were up year-over-year, thanks to gains in both service and equipment revenues. Also, service revenues were up almost 2% sequentially. Strong sales in BYOD supported that growth. Our upgrade rate was down year-over-year, but our equipment revenues were up, reflecting customers' purchasing habits and their choice of more expensive devices. But even with these strong sales, margins were very good with service margins coming in over 50% on a comparable basis. Looking ahead, we expect positive service revenue growth for the full year on a comparable basis. Turning to our Entertainment Group. We continue to see the impact of the video transition in our revenues and our margins. This would take a while to work through, and we expect it to continue the rest of the year. But we are seeing some sequential stability in both revenues and margins. We're making changes to drive revenues and effectively manage the transition. We're going to introduce some promotional pricing that impacted revenues in the past, and we now have new features on our next-generation platform that will drive additional revenue opportunities such as cloud DVR, a more robust VOD experience with new pay-per-view options and an additional stream capability. John Donovan is going to walk you through those plans in a few minutes. Also helping is AdWorks, which continues to grow at a double-digit rate and has now an annualized revenue stream of over $1.8 billion. Moving to our Business Solutions group. Revenues were down as gains in wireless and strategic business services helped offset declines in legacy services. Business wireless with strong growth, up more than 4%. This is driven by both equipment and service revenues. Wireline revenues were down more than 4% year-over-year. We still expect tax reform to produce a lift in communication spend, but we just haven't seen it yet. Wireline EBITDA margins were up slightly on a comparable basis. Cost efficiencies continue to offset pressure from legacy products and our investments in FirstNet. In our International business, solid customer performance helped to offset currency pressures. Revenues were stable year-over-year, while margins were pressured by World Cup expenses as well as foreign exchange. Now let's look at Time Warner's second quarter financials on Slide 7. Time Warner had strong growth at all operating conditions on a comparable basis. This includes strong subscription revenue growth on both Turner and HBO. Turner also showed solid advertising revenue growth of 3%. Adjusted operating income was $1.8 billion, driven by increases at Warner and HBO. Now for some housekeeping items. With recent FASB accounting rules, the Time Warner merger and purchase price accounting rules, there's going to be a lot of new information included in our results. We're going to do our best to make that easy for you to understand. First, we'll file pro formas with the SEC in August. Second, we have posted the full second quarter results for Time Warner on our Investor Relations website. This includes the Time Warner historical results, trending schedules, all the information you're accustomed to seeing. Finally, as you're updating your models, keep in mind the following: Results will continue to be reported at the divisional level, but there are certain things that will be eliminated in the Corporate and Other segment, including about $3 billion of annual inter-company content revenues and purchase accounting impacts on customer base and deferred production costs. We're very excited that Time Warner is part of the AT&T family and the WarnerMedia as part of the AT&T family, and John Stankey is going to provide more insights and highlights in a few minutes. Now let's look at our 2018 outlook with Time Warner included. We're raising adjusted earnings per share growth to the upper end of the $3.50 range with WarnerMedia included. Year-to-date, we're already seeing 15% growth. Impact of tax reform, improving wireless service and advertising revenues as well as the addition of Time Warner support strong adjusted EPS growth even with the additional shares issued as part of the deal. Looking at free cash flow. Our free cash flow guidance at the beginning of the year was standalone. We expect most of the benefit of the Time Warner free cash flow for the last half of the year, about $2 billion, will be absorbed by integration and deal costs, including severance costs, retention incentives, legal fees, bankers' costs and interest expense prior to close. When you consider those items and slightly lower cash capital spending, we're raising expected free cash flow to the upper end of the $21 billion range with dividend coverage in the low 60% range, and that's even with the additional shares and dividend responsibility from the merger with Time Warner. Now that we are halfway through the year, we also have a better view of CapEx. Capital investment is expected to be in the $25 billion range, but that will be $22 billion of CapEx on our cash flow statements after you net out our FirstNet reimbursements and some of the vendor financing opportunities that our team has pursued. A primary focus for us this year and the next few years is deleveraging the business. We have a strong business that generates a ton of cash and EBITDA, and we are very confident in the deleveraging targets that we have given you. Let me recap them now. Net debt to EBITDA is projected to be in the 2.9x range by the end of this year and a 2.5 range by the end of next year. To reach that target, we expect EBITDA growth. We'll use excess cash to pay down debt, and as always, we'll continue to look for ways to monetize non-strategic assets. You've seen that recently with the data center deal and our pending sale of broadcast 600 spectrum. We expect to return to historic debt levels in the 1.8 times range by the end of 2022. That's the financial summary. Now I'll turn it over to Randall. Randall?
