The industry continues to be challenged by the shortage of qualified drivers and erratic fuel prices. We achieved minimal fleet growth in the 3rd quarter of 2012 compared to the third quarter of 2011. We continue to aggressively manage our fuel cost through newer model revenue equipment and strategic fuel purchasing decisions. Fuel expense increased $1.5 million or 3.6% during the quarter.

The average cost of diesel fuel increased approximately $0.40 per gallon during the 3rd quarter of 2012 and the spread between the highest price and lowest price during the quarter was $0.45 per gallon. Fuel price swings of this nature will continue to have negative impacts to our earnings.
