Accounting Policies and Related Matters [Abstract]
Accounting Policies and Related Matters	2. Accounting Policies and Related Matters Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with instructions to Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2017 are not necessarily an indication of the results that may be expected for the year ending December 31, 2017. For further information, refer to the financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2016. New Accounting Standards In May 2014, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”. The standard is a comprehensive new revenue recognition model that requires revenue to be recognized in a manner to depict the transfer of goods or services to a customer at an amount that reflects the consideration expected to be received in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted beginning after December 15, 2016. A reporting entity may apply the new standard using either a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption or a full retrospective approach. We are currently evaluating the impact that the adoption of the standard will have on our consolidated financial statements and have not yet determined the method by which we will adopt the new standard. A significant source of our revenue is generated through leasing arrangements, which are specifically excluded from the new standard. We expect that the new standard will affect our accounting policies related to non-lease revenue, including certain fees in our RIDEA joint ventures, common area maintenance in our outpatient medical properties and real estate sales. Under ASU 2014-09, revenue recognition for real estate sales is mainly based on the transfer of control versus current guidance of continuing involvement. We expect that the new guidance will result in more transactions qualifying as sales of real estate and being recognized at an earlier date than under the current guidance. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities,” which will require entities to measure their investments at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. The practicability exception will be available for equity investments that do not have readily determinable fair values. ASU 2016-01 is effective for fiscal years and interim periods within those years, beginning after December 15, 2017. We are currently evaluating the impact that the standard will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize assets and liabilities on their balance sheet related to the rights and obligations created by most leases, while continuing to recognize expenses on their income statements over the lease term. It will also require disclosures designed to give financial statement users information regarding amount, timing, and uncertainty of cash flows arising from leases. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the earliest comparative period in the financial statements. We are currently evaluating the impact of this standard on our consolidated financial statements. We believe that the adoption of this standard will likely have a material impact to our consolidated balance sheet for the recognition of certain operating leases as right-of-use assets and lease liabilities. We are in the process of analyzing our lease portfolio and evaluating systems to comply with the standard’s retrospective adoption requirements. In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting”. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. We adopted ASU 2016-09 on January 1, 2017. The standard allows companies to make a policy election as to whether they will include an estimate of awards expected to be forfeited or whether they will account for forfeitures as they occur. We have elected to account for forfeitures as they occur. This election had an immaterial impact on our consolidated financial statements. The standard also requires an employer to classify as a financing activity in the statement of cash flow the cash paid to a tax authority when shares are withheld to satisfy the employer’s statutory income tax withholding obligation. This standard is required to be applied on a retrospective basis and resulted in an increase in net cash provided by operating activities and a decrease in net cash used in financing activities of $6,897,000 for the three months ended March 31, 2016. Upon adoption, no other provisions of ASU 2016-09 had an effect on our unaudited consolidated financial statements or related footnote disclosures. In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments”. This standard requires a new forward-looking “expected loss” model to be used for receivables, held-to-maturity debt, loans, and other instruments. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019, and early adoption is permitted for fiscal years beginning after December 15, 2018. We are currently evaluating the impact that the standard will have on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Clarifying the Definition of a Business”. This standard changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. ASU 2017-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. A reporting entity must apply ASU 2017-01 using a prospective approach. We adopted ASU 2017-01 on January 1, 2017 and as a result, have classified our real estate acquisitions completed during the three months ended March 31, 2017 as asset acquisitions rather than business combinations due to the fact that substantially all of the fair value of the gross assets acquired were concentrated in a single asset or group of similar identifiable assets. We have recorded identifiable assets acquired, liabilities assumed and any noncontrolling interests associated with any asset acquisitions at cost on a relative fair value basis and have capitalized transaction costs incurred.
