Thanks, Adam, and good afternoon, everyone. Now to Slide 5. Positive trends have continued in the first quarter, as demonstrated by the graphs. The graph on the left side of Slide 5 charts the progress made in our top line revenue growth, excluding fuel surcharge in the first quarter of each of the last 3 years.
As demonstrated by the graph on the right, we've experienced revenue growth, excluding fuel surcharge for 10 consecutive quarters. On Slide 6, we illustrate the earnings growth trends over the last 3 years, not including the noncash $4 million pretax, $3.9 million after-tax charge in the first quarter of 2012.
The first quarter of 2011 was one of the most challenging quarters in our company's history. We experienced rapidly escalating fuel prices, with weaker demand specifically in the West.
In 2012, we responded with improved per unit operating fundamentals, fuel MPG improvements and revenue growth. As demonstrated by both graphs, our 2012 results show significant improvement in both EPS and net income when compared to the prior year.
On Slide 7, we've summarized our first quarter performance in some of the key operating statistics. All stats are year-over-year comparisons from the first quarter of 2012 to the first quarter of 2011.
Revenue per tractor, excluding fuel surcharge, improved 10.3%. Miles per tractor increased 7.3%. Revenue per loaded mile increased 3.1%. Revenue per total mile increased 2.8%, and length of haul increased 2.6%.
Our non-paid empty mile percentage ended the first quarter at 10.7%. We ended the quarter with a tractor fleet of 4,032 tractors, including owner operators, an increase of 154 tractors from the end of the first quarter of 2011.
On Slide 8, we show the average revenue per tractor, excluding fuel surcharge for the first quarter in each of the last 4 years. The revenue per tractor for the quarter has grown from roughly $35,400 in the first quarter of 2011 to just over $39,000 in the first quarter of 2012.
Now to Slide 9. We experienced revenue growth in all businesses. Our largest business, Dry Van and Refrigerated, showed meaningful year-over-year improvement in their operating ratios. Our Port & Rail Services business did experience an increase in operating ratio, as we continue to build out our network. We expect to see improved results in future quarters.
Our brokerage business continues to grow revenues at a double-digit rate while operating in the low 90s. On a consolidated basis, we improved our operating ratio 300 basis points to an 86.4% and increased revenue, excluding fuel surcharge, by 16.7% when compared to the previous year.
Now onto Slide 10. We are focused and committed to creating and operating Knight in a way that generates industry-leading margins and revenue growth. We believe our decentralized model affords us strategic advantages that can be leveraged from one business or transportation mode to another, while providing greater value to our customers.
On Slide 11, we continue to bring our businesses together to provide our customers with services that meet their changing needs 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, Dry Van, Refrigerated, Port & Rail Services, Intermodal and Brokerage, continue to complement each other, while providing premium cost competitive service to our diversified customer base.
Since 2004, we have diversified our business model by expanding our service offerings. Our Dry Van business went from comprising 99% of our revenue in 2004 to 68% in 2011.
I'll now hand it off to Kevin Knight to discuss the next couple of slides.
