11) SEGMENT REPORTING

Our reportable operating segments consist of acute care hospital services and behavioral health care services. The “Other” segment column below includes centralized services including, but not limited to, information technology, purchasing, reimbursement, accounting and finance, taxation, legal, advertising and design and construction. The chief operating decision making group for our acute care services and behavioral health care services is comprised of our Chief Executive Officer, the President and the Presidents of each operating segment. The Presidents for each operating segment also manage the profitability of each respective segment’s various facilities. The operating segments are managed separately because each operating segment represents a business unit that offers different types of healthcare services or operates in different healthcare environments. The accounting policies of the operating segments are the same as those described in the summary of significant accounting policies included in this Annual Report on Form 10-K for the year ended December 31, 2017. The corporate overhead allocations, as reflected below, are utilized for internal reporting purposes and are comprised of each period’s projected corporate-level operating expenses (excluding interest expense). The overhead expenses are captured and allocated directly to each segment, to the extent possible, based upon each segment’s respective percentage of total operating expenses.
