[1] The aggregate cost of properties for federal income tax purposes is approximately $3.6 billion at December 31, 2016.

[2] Depreciation is calculated using estimated useful lives of depreciable assets up to 50 years for prison facilities.

[3] CoreCivic recorded non-cash impairments during the fourth quarter of 2014 to write down the book values of the Queensgate and Mineral Wells facilities to the estimated fair values assuming asset sales for uses other than correctional facilities.

[4] We transitioned operations from the 1,154-bed San Diego Correctional Facility to the newly constructed 1,482-bed Otay Mesa Detention Center in the fourth quarter of 2015. The San Diego Correctional Facility was subject to a ground lease with the County of San Diego. Upon expiration of the lease on December 31, 2015, ownership of the facility automatically reverted to the County of San Diego.

[5] The South Texas Family Residential Center is subject to a lease agreement with a third-party lessor. This agreement resulted in CoreCivic being deemed the owner of the newly constructed assets for accounting purposes, in accordance with ASC 840-40-55, formerly Emerging Issues Task Force No. 97-10, "The Effect of Lessee Involvement in Asset Construction."
