Thanks, Adam, and good afternoon, everyone. Now to Slide 5. We have experienced revenue growth at an accelerated pace. That's compared to the broader truckload freight market. Since the second quarter of 2009 and most likely the bottom of the recent downturn, we have demonstrated market share growth momentum that we expect to continue into future quarters. The bar graph on the left shows the positive trend in our revenue growth, excluding fuel surcharge in the fourth quarter for each of the last 3 years. The graph to the right shows that our year-over-year revenue growth trend has continued for 9 consecutive quarters, a trend we expect to continue.
On Slide 6, we illustrate the earnings growth trends demonstrated by the growing fourth quarter EPS trend in each of the last 3 years and in our increasing net income for the fourth quarter also in each of the last 3 years.
Now on to Slide 7. Here we've summarized our fourth quarter performance and some of the key operating statistics. All stats are year-over-year comparisons for the fourth quarter of 2011 to the fourth quarter of 2010. Revenue excluding fuel surcharge per tractor improved 6.8%. Miles per tractor increased 4.1%. Revenue per total mile increased 2.6%. And revenue per loaded mile increased 2.6%. And nonpaid empty mile percent declined by 0.4%.
Additionally, we ended the quarter with a tractor fleet of 3,976 tractors, including owner operators, which represents a 110-tractor increase from the end of the fourth quarter of 2010. We expect to cross the 4,000-tractor mark in the first quarter of 2012.
And now on to Slide 8. Here we take a deeper look into the strengthening operating fundamentals. The improvement for the fourth quarter of 2011 was healthy, but perhaps even more encouraging is that the positive trend -- or the positive performance is part of a steady trend of improving operating fundamentals. For example, the graph on the left illustrates the revenue growth excluding fuel surcharge in our average revenue per tractor. Revenue per tractor for the quarter has grown from roughly $36,000 in Q4 of '09 to $37,400 in Q4 of 2010, and most recently to nearly $40,000 in the fourth quarter of 2011. This is an 11.1% increase from '09 to 2011.
On the right, we illustrate the changes in miles per tractor and rate per loaded mile over the past several quarters. Miles per tractor improved 4.1% in the fourth quarter as the rate of year-over-year improvement has increased in each of the recent 3 quarters. Rate per loaded mile has been on the rise over the past 2 years, a trend we expect will continue.
Now to Slide 9. We experience revenue growth in every business we operate. In addition to the revenue growth, most of our businesses lowered their operating ratios meaningfully year-over-year. So our largest businesses, Dry Van and Refrigerated, operated with operating ratios in the low 80s with an 82.4% and an 81.7%, respectively.
Now to Slide 10. Our objective as a business is very simple and straightforward. We are focused and committed on creating and operating businesses that generate industry-leading margins and revenue growth.
If you move to Slide 11, we've put together a graph. This is a way of comparing publicly traded trucking companies, particularly their truckload businesses, by their respective margin and growth rates. We have been consistently successful at generating a mid- to high-teen operating margin while growing the top line with a double-digit growth rate. It's about both margin and growth for us.
And onto Slide 12. We continue to bring our businesses together to provide our customers with services that meet their requirements while leveraging our established geographic network and low-cost operating model. We believe there are many opportunities to grow with our existing customers and introduce new customers to our multiple services network. Our businesses, the Dry Van, Refrigerated, Port & Rail Services, Intermodal and Brokerage businesses, continue to complement each other while providing premium, cost competitive service for a diversified customer base.
I'll now hand off to Kevin Knight to discuss the next couple of slides.
