Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The summary of significant accounting policies presented below is designed to assist in understanding our condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to U.S. generally accepted accounting principles (“GAAP”) in all material respects and have been consistently applied in preparing our accompanying condensed consolidated financial statements. Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our subsidiaries and any consolidated variable interest entities (“VIEs”). All inter-company balances and transactions have been eliminated in the accompanying condensed consolidated financial statements. Interim Unaudited Financial Data Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments, which are, in our opinion, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such results may be less favorable for the full year. Our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2014 Annual Report on Form 10-K. Variable Interest Entities During 2014, we made loans totaling $80.5 million to five entities to acquire MOBs in order to facilitate potential Internal Revenue Code Section 1031 tax-deferred exchanges (the “Exchanges”). As of December 31, 2014, our consolidated financial statements included the five VIEs as we were deemed to be the primary beneficiary. During the second quarter of 2015, we elected not to consummate the five outstanding Exchanges and, accordingly, the rights to the title and interests of the MOBs were transferred to us. Real Estate Investments Depreciation expense of buildings and improvements for the three months ended September 30, 2015 and 2014, was $26.9 million and $22.6 million, respectively. Depreciation expense of buildings and improvements for the nine months ended September 30, 2015 and 2014, was $74.9 million and $65.0 million, respectively. Recoverability of Real Estate Investments Real estate investments are evaluated for potential impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Impairment losses are recorded when indicators of impairment are present and the carrying amount of the asset is greater than the sum of future undiscounted cash flows expected to be generated by that asset over the remaining expected holding period. We would recognize an impairment loss when the carrying amount is not recoverable to the extent the carrying amount exceeds the fair value of the property. The fair value is generally based on discounted cash flow analyses. In performing the analysis we consider executed sales agreements or management’s best estimate of market comparables, future occupancy levels, rental rates, capitalization rates, lease-up periods and capital requirements. See Note 4 for further discussion. Recently Issued or Adopted Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (i.e., payment) to which the company expects to be entitled in exchange for those goods or services. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. In July 2015, the FASB deferred the effective date of ASU 2014-09 to the first interim period within annual reporting periods beginning after December 15, 2017 along with the ability to early adopt as of the original effective date. We do not anticipate early adoption and we are evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments in ASU 2015-02 affect the following areas: (i) limited partnerships and similar legal entities; (ii) evaluating fees paid to a decision maker or a service provider as a variable interest; (iii) the effect of fee arrangements on the primary beneficiary determination; (iv) the effect of related parties on the primary beneficiary determination; and (v) certain investment funds. ASU 2015-02 is effective for fiscal years and for interim periods within those fiscal years, beginning after December 15, 2015 with early adoption permitted. We are evaluating this guidance, however, we do not believe ASU 2015-02 will have a significant impact on our consolidated financial statements, however, we believe ASU 2015-02 will likely increase our disclosure. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 changes the presentation of debt issuance costs by requiring these costs related to a recognized debt liability to be presented in the consolidated balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by these amendments. In August 2015, the FASB issued ASU 2015-15 to include the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-03 and 2015-15 are effective for the fiscal years beginning after December 15, 2015, and requires retrospective application. We do not believe the adoption of ASU 2015-03 and 2015-15 will have a significant impact on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 eliminates the requirement that an acquirer in a business combination has to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amount of the adjustment, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2015 with early adoption permitted. We are evaluating this guidance, however, we do not believe the adoption of ASU 2015-16 will have a significant impact on our consolidated financial statements.

Summary of Significant Accounting Policies

The summary of significant accounting policies presented below is designed to assist in understanding our condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to U.S. generally accepted accounting principles (“GAAP”) in all material respects and have been consistently applied in preparing our accompanying condensed consolidated financial statements.

Basis of Presentation

Our accompanying condensed consolidated financial statements include our accounts and those of our subsidiaries and any consolidated variable interest entities (“VIEs”). All inter-company balances and transactions have been eliminated in the accompanying condensed consolidated financial statements.

Interim Unaudited Financial Data

Our accompanying condensed consolidated financial statements have been prepared by us in accordance with GAAP in conjunction with the rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, our accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. Our accompanying condensed consolidated financial statements reflect all adjustments, which are, in our opinion, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim periods. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such results may be less favorable for the full year. Our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2014 Annual Report on Form 10-K.

Variable Interest Entities

During 2014, we made loans totaling $80.5 million to five entities to acquire MOBs in order to facilitate potential Internal Revenue Code Section 1031 tax-deferred exchanges (the “Exchanges”). As of December 31, 2014, our consolidated financial statements included the five VIEs as we were deemed to be the primary beneficiary. During the second quarter of 2015, we elected not to consummate the five outstanding Exchanges and, accordingly, the rights to the title and interests of the MOBs were transferred to us.

Real Estate Investments

Depreciation expense of buildings and improvements for the three months ended September 30, 2015 and 2014, was $26.9 million and $22.6 million, respectively. Depreciation expense of buildings and improvements for the nine months ended September 30, 2015 and 2014, was $74.9 million and $65.0 million, respectively.

Recoverability of Real Estate Investments

Real estate investments are evaluated for potential impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Impairment losses are recorded when indicators of impairment are present and the carrying amount of the asset is greater than the sum of future undiscounted cash flows expected to be generated by that asset over the remaining expected holding period. We would recognize an impairment loss when the carrying amount is not recoverable to the extent the carrying amount exceeds the fair value of the property. The fair value is generally based on discounted cash flow analyses. In performing the analysis we consider executed sales agreements or management’s best estimate of market comparables, future occupancy levels, rental rates, capitalization rates, lease-up periods and capital requirements. See Note 4 for further discussion.

Recently Issued or Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. ASU 2014-09 is a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration (i.e., payment) to which the company expects to be entitled in exchange for those goods or services. In adopting ASU 2014-09, companies may use either a full retrospective or a modified retrospective approach. In July 2015, the FASB deferred the effective date of ASU 2014-09 to the first interim period within annual reporting periods beginning after December 15, 2017 along with the ability to early adopt as of the original effective date. We do not anticipate early adoption and we are evaluating the impact of adopting ASU 2014-09 on our consolidated financial statements.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments in ASU 2015-02 affect the following areas: (i) limited partnerships and similar legal entities; (ii) evaluating fees paid to a decision maker or a service provider as a variable interest; (iii) the effect of fee arrangements on the primary beneficiary determination; (iv) the effect of related parties on the primary beneficiary determination; and (v) certain investment funds. ASU 2015-02 is effective for fiscal years and for interim periods within those fiscal years, beginning after December 15, 2015 with early adoption permitted. We are evaluating this guidance, however, we do not believe ASU 2015-02 will have a significant impact on our consolidated financial statements, however, we believe ASU 2015-02 will likely increase our disclosure.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 changes the presentation of debt issuance costs by requiring these costs related to a recognized debt liability to be presented in the consolidated balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by these amendments. In August 2015, the FASB issued ASU 2015-15 to include the presentation and subsequent measurement of debt issuance costs associated with line-of-credit arrangements. ASU 2015-03 and 2015-15 are effective for the fiscal years beginning after December 15, 2015, and requires retrospective application. We do not believe the adoption of ASU 2015-03 and 2015-15 will have a significant impact on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, Business Combinations - Simplifying the Accounting for Measurement-Period Adjustments. ASU 2015-16 eliminates the requirement that an acquirer in a business combination has to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amount of the adjustment, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. ASU 2015-16 is effective for fiscal years beginning after December 15, 2015 with early adoption permitted. We are evaluating this guidance, however, we do not believe the adoption of ASU 2015-16 will have a significant impact on our consolidated financial statements.
