In this Quarterly Report, “we,” “us,” “our” and the “Trust” refer to Universal Health Realty Income Trust and its subsidiaries. In this Quarterly Report on Form 10-Q, the term “revenues” does not include the revenues of the unconsolidated limited liability companies (“LLCs”) in which we have various non-controlling equity interests ranging from 33% to 95%. As of September 30, 2016, we had investments in five jointly-owned LLCs/LPs which own medical office buildings, all of which are accounted for by the equity method (see Note 5). These LLCs are included in our financial statements for all periods presented on an unconsolidated basis since they are not variable interest entities for which we are the primary beneficiary, nor do we hold a controlling voting interest. The financial statements included herein have been prepared by us, without audit, pursuant to the rules and regulations of the SEC and reflect all normal and recurring adjustments which, in our opinion, are necessary to fairly present results for the interim periods. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations, although we believe that the accompanying disclosures are adequate to make the information presented not misleading. It is suggested that these financial statements be read in conjunction with the financial statements, the notes thereto and accounting policies included in our Annual Report on Form 10-K for the year ended December 31, 2015.

In this Quarterly Report on Form 10-Q, the term “revenues” does not include the revenues of the unconsolidated limited liability companies (“LLCs”) in which we have various non-controlling equity interests ranging from 33% to 95%. As of September 30, 2016, we had investments in five jointly-owned LLCs/LPs which own medical office buildings, all of which are accounted for by the equity method (see Note 5). These LLCs are included in our financial statements for all periods presented on an unconsolidated basis since they are not variable interest entities for which we are the primary beneficiary, nor do we hold a controlling voting interest.

The financial statements included herein have been prepared by us, without audit, pursuant to the rules and regulations of the SEC and reflect all normal and recurring adjustments which, in our opinion, are necessary to fairly present results for the interim periods.
