Item 2. Properties

The following table lists, by state, the number of hospitals (general, acute care, psychiatric and rehabilitation) directly or indirectly owned and operated by us as of December 31, 2022:

In addition to the hospitals listed in the above table, we directly or indirectly operate 126 freestanding surgery centers and 21 freestanding endoscopy centers. We also operate medical office buildings in conjunction with some of our hospitals. These office buildings are primarily occupied by physicians who practice at our hospitals. Twelve of our general, acute care hospitals and five of our other properties have been mortgaged to support our obligations under our senior secured cash flow credit facility.

We maintain our headquarters in approximately 2,031,000 square feet of space in the Nashville, Tennessee area. In addition to the headquarters in Nashville, we maintain regional service centers related to our shared services initiatives. These service centers are located in markets in which we operate hospitals.

We believe our headquarters, hospitals and other facilities are suitable for their respective uses and are, in general, adequate for our present needs. Our properties are subject to various federal, state and local statutes and ordinances regulating their operation. Management does not believe that compliance with such statutes and ordinances will materially affect our financial position or results of operations.
