The Company depreciates its leasehold improvements over the shorter of their estimated useful lives or the terms of the leases including renewal periods that are reasonably assured. The Company’s construction in progress primarily consists of expansions to facilities that are owned by the Company. Interest capitalized in property and equipment for the years ended December 31, 2015 and December 31, 2014 was not significant.

Depreciation expense was $87.5 million, $79.8 million and $78.8 million, respectively, for the years ended December 31, 2015, 2014 and 2013, respectively.

At December 31, 2015 and 2014, the Company had $17.1 million and $17.1 million, respectively, of assets recorded under capital leases related to land, buildings and improvements.

Depreciation expense related to assets recorded under capital leases for the years ended December 31, 2015, 2014 and 2013 was $1.0 million, $1.3 million and $1.0 million, respectively, and is included in Depreciation and Amortization in the accompanying consolidated statements of operations.
