MEDICAL PROPERTIES TRUST INC Segments Disclosure

13. Segment Disclosures

We manage our business and report financial results as one business segment. This is consistent with the manner in which our chief operating decision maker ("CODM"), our executive team made up of our Chief Executive Officer and Chief Financial Officer, evaluates performance and makes resource and operating decisions for the business.

Our primary business strategy and source of revenue is from the acquisition and development of healthcare facilities that are leased to healthcare operating companies under long-term net leases, which require the tenant to bear most of the costs associated with the property. The majority of our leased assets are owned 100%; however, we do own some leased assets through joint ventures with other partners. We also may make mortgage loans to healthcare operators collateralized by their real estate. In addition, we may make noncontrolling investments in our tenants, from time-to-time, typically in conjunction with larger real estate transactions with the tenant, which may enhance our overall return and provide for certain minority rights and protections. Although we generate our revenues from these investments in the U.S. and eight other countries across multiple property types, we centrally manage these business activities on a consolidated basis. The accounting policies of our business segment are the same as those described in the summary of significant accounting policies.

The CODM evaluates performance and makes resource and operating decisions for the business on a consolidated basis using consolidated net income from our consolidated statements of net income as our primary GAAP profit measure supplemented by consolidated funds from operations ("FFO"). We use net income and FFO to monitor expected versus actual results to assess performance. The measure of segment assets is total assets as reported on our consolidated balance sheets. We compute FFO in accordance with the definition provided by the National Association of Real Estate Investment Trusts, which represents consolidated net (loss) income (computed in accordance with GAAP), excluding gains (losses) on sales of real estate and impairment charges on real estate assets, plus real estate depreciation and amortization, including amortization related to in-place lease intangibles, and after adjustments for unconsolidated partnerships and joint ventures.

Given FFO excludes real estate related depreciation and amortization expense by definition and due to our typical net lease structure which requires our tenants to bear most of the costs associated with our properties (including property taxes, insurance, etc.), the primary expenses reviewed by the CODM include general and administrative and interest expenses from our consolidated statements of net income.
