16.	SEGMENT REPORTING

As of December 31, 2017, CoreCivic owned and managed 70 facilities, and managed seven facilities it did not own. In addition, CoreCivic owned 12 properties that it leased to third parties. Management views CoreCivic's operating results in one operating segment. However, the Company has chosen to report financial performance segregated for (1) owned and managed facilities and (2) managed-only facilities as the Company believes this information is useful to users of the financial statements. Owned and managed facilities include the operating results of those facilities placed into service that were owned or controlled via a long-term lease and managed by CoreCivic. Managed-only facilities include the operating results of those facilities owned by a third party and managed by CoreCivic. The operating performance of the owned and managed and the managed-only facilities can be measured based on their net operating income. CoreCivic defines facility net operating income as a facility's operating income or loss from operations before interest, taxes, asset impairments, depreciation, and amortization.

The revenue and net operating income for the owned and managed and the managed-only facilities and a reconciliation to CoreCivic's operating income is as follows for the three years ended December 31, 2017, 2016, and 2015 (in thousands):
