Thank you. And good morning, everyone, and welcome to Caterpillar's Second Quarter Earnings Conference Call. I'm Mike DeWalt, the Director of Investor Relations. I'm pleased to have our Chairman and CEO, Doug Oberhelman; our Group President and CFO, Ed Rapp, here on the call today. And because we'll be discussing the Bucyrus acquisition, I'm also pleased to have Steve Wunning with us today. Steve is our Group President that heads the Resource Industries business. The call today is copyrighted by Caterpillar Inc., and any use, recording or transmission of any portion of the call without the expressed written consent of Caterpillar is strictly prohibited. If you'd like a copy of today's call transcript, we'll be posting it in the Investor section of our caterpillar.com website. It'll be in the section labeled Results Webcast. Now this morning, we'll be discussing forward-looking information that involves risks, uncertainties and assumptions that could cause our actual results to differ materially from the forward-looking information. A discussion of some of the factors that either individually or in the aggregate, we believe could make actual results differ materially from our projections that can be found in our cautionary statements under Item 1A, which Risk Factors, of our Form 10-K filed with the SEC on February 22, 2011, and it's also on our forward-looking statements language contained in today's release. Now this morning's call format will be a little different than we've done in the past. I'll cover our second quarter results and the new outlook for 2011 then I'll turn it over to Ed Rapp and Steve Wunning to take you through the highlights of the Bucyrus acquisition that we closed on July 8. All of that should take about 30 minutes and then leave us about an hour for your questions. Now if you haven't done so already, you should download the Bucyrus presentation from the Investor area of the cat.com website. When you go to the Investor section of cat.com, you'll see a menu on the left-hand side of the screen, and the material that we're going to use today is in the Events & Presentations area. Okay. This morning, we were pleased to report financial results for the second quarter that were significantly better than last year. Sales and revenues were $14.2 billion, and that's the highest of any quarter in history and up 37% from the second quarter 2010. Sales and revenues were up in every geographic region. North America was up 36%; Latin America, 34%; Europe, Africa/Middle East, 51%; and Asia/Pacific was up 41%. Now to provide a consistent comparison with our 2010 results and our previous outlook, we're reporting our results this year with and without the impacts related to the Bucyrus, and we're starting that this quarter. There's a non-GAAP reconciliation in today's earnings release, and if you haven't seen the release yet, you can also find that on the cat.com website. Now excluding Bucyrus-related items that were in our second quarter, profit was $1.72 a share, and that's $0.63 or about 58% higher than the second quarter of 2010. While we didn't close Bucyrus until after the end of the second quarter, we did have $204 million in acquisition costs related to Bucyrus in the quarter. The most significant Bucyrus-related items were down on our other income and expense line below operating profit. And the largest item was the loss of $124 million in the quarter on interest rate swap contracts that we put in place in early -- or late 2010 and early 2011. At the time we put the contracts in place, interest rates were trending up. And considering the amount of debt that we needed to issue to complete the acquisition, we put the swap contracts in place to mitigate the potential for even higher rates. However, between then and the time we issued the debt, rates, in fact, did not go up. They went down. And while that's a very good thing and we were able to issue debt at historically low rates, it did result in losses on the swaps. However, over the life of the debt, the lower rates will be much more of a benefit than the loss we had on the swaps. Now in addition to the loss on the swaps, on that other income and expense line, in the second quarter, we had $38 million of expense related to the bridge financing facility that we put in place. In our operating cost, there was expense related to the acquisition and integration planning, and we incurred about $11 million of interest expense in the quarter on that debt that we issued back in late May. So in total, Bucyrus-related costs in the quarter were $204 million or about $0.20 a share. As a result of that, our total profit in the quarter, including those Bucyrus impacts, was $1.52 a share. Just for your reference, in today's release, we have a Q&A in the back. And Q&A #2 on Page 17 does a pretty good job of laying out the Bucyrus-related impacts in the quarter. Now related to the quarter, I should mention 3 other items that you may want to consider as you review our results, and they're all covered in today's earnings release. On the positive side, we had favorable discrete tax adjustments of $72 million. On the negative side, currency impacts were negative to operating profit, $102 million versus the second quarter of 2010. And the third item is short-term incentive compensation. I'm going to talk about the outlook in a minute, but we raised it, and that had the impact of adding $85 million more incentive compensation in the second quarter than we had in the first quarter, and incentive comp was $95 million higher in the second quarter than it was in the second quarter of 2010. As you do your analysis of our second quarter results, I'm sure many of you will do the math and calculate the incremental operating margin. To help you out with that, we've also included a Q&A. It's #12 on Page 20 of today's release. Now when you calculate incremental margin, your purpose is likely to get another data point on operating performance. We think it makes the analysis more reasonable if you pull out the impact of acquisitions to make it apples-to-apples. Excluding the impact of acquisitions, our consolidated incremental operating profit was 18% in the quarter. That's down from the first quarter, but it's consistent with the outlook we discussed during our conference call at the end of the first quarter. We said then that the first quarter was seasonally light for costs, that price realization was moderate, and R&D costs were expected to go up. In addition, we expected that the negative impact we were anticipating as a result of the disaster in Japan would largely be in the second quarter. Now when you look at the incremental margins, there's another important point you should consider, and that's the impact of currency. A weaker dollar compared with the second quarter of 2010 meant that our sales actually benefited $351 million in the quarter. However, the impact on cost was more. It was $453 million, and that resulted in a negative impact of $102 million on operating profit. If you were to adjust for the currency impact, the incremental operating profit pull-through was 24% in the quarter. In this morning's release, we also updated the outlook for 2011. And we are reporting it also with and without the impact of Bucyrus, and we're doing that to provide a more consistent comparison with our previous outlook. So excluding the impacts of Bucyrus, we increased the outlook today. For sales and revenues, we took it up to $54 billion to $ 55 billion -- I'm sorry, $54 billion to $56 billion in sales and profit of $6.75 to $7.25 a share. That's an increase at the top, the bottom and the midpoint of $2 billion in sales and revenues and $0.50 a share in profit. Our previous outlook, as a reminder, was the sales range -- the sales revenues range of $52 billion to $54 billion and a profit range of $6.25 to $6.75 a share. Now because we've completed the Bucyrus acquisition, we're also providing a new company outlook for 2011 that includes Bucyrus, and this is the first outlook that we've had where we've included Bucyrus. The expected impact of Bucyrus includes the vast majority of the upfront integration and deal-related costs that we expect on the deal but only a half year of actual operating results from Bucyrus. In total, we expect the 2011 impact of the acquisition will be positive to sales about $2 billion but negative to profit per share $0.50. Including Bucyrus then, the sales and revenues outlook is $56 billion to $58 billion, and the profit outlook is $6.25 to $6.75 a share. Now the factors driving that negative impact this year related to Bucyrus include about $700 million of upfront and deal-related integration costs in 3 major areas. The first, we've already talked about, and that's the loss on the interest rate swaps. And for the year, that's about $150 million. Second, we're expecting about $250 million of additional cost this year related to the Bucyrus inventory step-up. And third, we expect another $300 million of costs related to the acquisition and integration expenses like severance costs for Bucyrus executives, cost for the bridge financing, legal cost, advisory fees and a host of other integration-related activities. Now when we announced the deal last November, we said that we expected about $0.50 per share of those upfront costs in the first year, and the $700 million that I reviewed is a bit higher than that for 2 main reasons. First, we didn't expect the interest rate swap losses. And second, the estimate of the inventory step-up is a little bit higher than we expected back in November. Now in addition to the $700 million of upfront costs this year on our outlook, it includes about $80 million of additional interest expense on that debt that we issued back at the end of May. Now partially offsetting those items, we expect operating profit from Bucyrus net of about $150 million of incremental intangible amortization to be about $300 million positive during the second half of 2011. I think we have a pretty good summary of the impacts of Bucyrus on 2011 results on Page 15 of today's release in the Outlook section. One more point, I think, it's good to make about the Bucyrus impact. And that is of that negative $0.15 or $0.50 per share this year, about half of it is behind us in the first half. It's actually in our first half results. The other half will be in the third and fourth quarter. Now I'll just make a couple of quick more points and then I'll turn it over to Ed to start the discussion on the Bucyrus acquisition, and the first of those 2 points is the disaster in Japan. And I'd like to thank our employees, our supply base and our dealers for the exceptional work that they've done. The recovery there has been faster and the net impact less than we anticipated. In the second quarter, sales were negatively impacted about $200 million, and operating profit was negatively impacted about $60 million. That's better than we expected. Our previous estimate was a negative impact of about $300 million for the year and a negative impact of about $100 million to operating profit for the year, most of which we expected in the second quarter. In fact, in Japan, production is now back to or above pre-disaster levels, and there's a good chance that we'll recover much of the sales shortfall later in the second half. Final point this morning is on cash flow, and it's a great story to tell. Our Machinery and Power Systems operating cash flow for the first half of the year was $4.1 billion, and that's a 63% improvement from the first half of 2010. And of that $4.1 billion, about $2.5 billion was in the second quarter. And it's that kind of performance in generating cash that helped us fund the Bucyrus acquisition without the need to issue new equity. Okay. That's the quarter and the outlook, and with that, I'm going to pass it over to Ed to start the discussion on Bucyrus.
