P. A. M. was able to produce more revenue with fewer assets in an asset-intensive business such as trucking.

Trucking is incongruous with what we've come to expect with the blue-collar economy these days. Productivity improvements mean that other industries are scaling down whereas it still takes one driver per truck to move goods, and there is little way around that. What's more, other industries can outsource, but trucking can't.

There was volume growth, but these results were driven by yield improvement and operating-margin improvement. We also saw productivity gain and more packages moved per employee.
