Depreciation expense was $52.6 million, $55.5 million, and $47.2 million in 2011, 2010, and 2009, respectively. The aforementioned depreciation expense excludes gains (losses) on the sale of property and equipment totaling $6.7 million, $4.3 million and ($0.1) million in 2011, 2010 and 2009, respectively, which are presented net in depreciation and amortization expense in the consolidated statements of operations.

We lease certain revenue equipment under capital leases with terms of 60 months. At December 31, 2011 and 2010, property and equipment included capitalized leases, which had capitalized costs of $21.3 million and $16.4 million, respectively, and accumulated amortization of $3.4 million and $1.6 million, respectively.  Amortization of these leased assets is included in depreciation and amortization expense in the consolidated statement of operations and totaled $1.8 million, $1.4 million, and $0.2 million during 2011, 2010, and 2009, respectively.

In 2009, we began a multi-year project to upgrade the hardware and software of our information systems. The goal upon completion of the project is to have uniform operational and financial systems across the entire Company as we believe this will improve customer service, utilization, and enhance our visibility into and across the organization. We incurred approximately $0.6 million and $0.8 million in 2011 and 2010, respectively, related to this system upgrade, and $0.6 million of these related amounts are included in construction in progress as the related systems were not implemented as of December 31, 2011. We have capitalized $3.4 million of these costs, which are reflected in property and equipment in the consolidated balance sheet.
