The company said, "What's happening in our business and in the economy overall is a mixed picture. Conditions in the world economy seem relatively stable, and we continue to expect slow growth in 2013. As we began 2013, we were concerned about economic growth in the United States and China and are pleased with the relative stability we have seen so far this year. In the United States, we are encouraged by progress so far and are becoming more optimistic on the housing sector in particular. In China, first quarter economic growth was slightly less than many expected, but in our view, remains consistent with slow growth in the world economy. In fact, our sales in China were higher in the first quarter of 2013 than they were in the first quarter of 2012, and machine inventories in China have declined substantially from a year ago. We have three large segments: Construction Industries; Power Systems; and Resource Industries, which is mostly mining. While expectations for Construction Industries and Power Systems are similar to our previous outlook, our expectations for mining have decreased significantly. Our revised 2013 outlook reflects a sales decline of about 50% from 2012 for traditional Cat machines used in mining and a decline of about 15% for sales of machines from our Bucyrus acquisition."
