Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information. Management is required to make estimates and assumptions in the preparation of financial statements in conformity with GAAP. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from management’s estimates. The consolidated financial statements include the accounts of HCP, Inc., its wholly-owned subsidiaries, joint ventures and VIEs that it controls through voting rights or other means. Intercompany transactions and balances have been eliminated upon consolidation. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows have been included. Operating results for the three and six months ended June 30, 2016 are not necessarily indicative of the results that may be expected for the year ending December 31, 2016. The accompanying unaudited interim financial information should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K filed with the SEC.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2016‑13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 is intended to improve financial reporting by requiring timelier recognition of credit losses on loans and other financial instruments held by financial institutions and other organizations. ASU 2016-13 is effective for fiscal years, and interim periods within, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within, beginning after December 15, 2018. The Company is evaluating the impact of the adoption of ASU 2016‑13 on January 1, 2020 to its consolidated financial position or results of operations. In May 2016, the FASB issued ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”). The amendments in ASU 2016-12 do not change the core principles of the guidance in the new revenue standard described in ASU No. 2014-09 below. Rather, the amendments in ASU 2016-12 provide practical expedients and improvements on the previously narrow scope of the standard. ASU 2016-12 is effective for fiscal years, and interim periods within, beginning after December 15, 2017. Early adoption is permitted at the original effective date of the new revenue standard (January 1, 2017). The Company is evaluating the impact of the adoption of ASU 2016-12 on January 1, 2018 to its consolidated financial position or results of operations. In March 2016, the FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 is intended to simplify accounting for share-based payment transactions. The areas for simplification in this update involve several aspects of accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. ASU 2016-09 is effective for fiscal years, and interim periods within, beginning after December 15, 2016. Early adoption is permitted. The Company is evaluating the impact of the adoption of ASU 2016-09 on January 1, 2017 to its consolidated financial position, results of operations or cash flows. In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”). ASU 2016-08 is intended to improve the operability and understandability of the implementation guidance on principal versus agent considerations. ASU 2016-08 is effective for fiscal years, and interim periods within, beginning after December 15, 2017. Early adoption is permitted at the original effective date of the new revenue standard described in ASU No. 2014-09 below (January 1, 2017). The Company is evaluating the impact of the adoption of ASU 2016-08 on January 1, 2018 to its consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 amends the current accounting for leases to (i) require lessees to put most leases on their balance sheets, but continue recognizing expenses on their income statements in a manner similar to requirements under current accounting guidance, (ii) eliminate current real estate specific lease provisions and (iii) modify the classification criteria and accounting for sales-type leases for lessors. ASU 2016-02 is effective for fiscal years, and interim periods within, beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of the adoption of ASU 2016-02 on January 1, 2019 to its consolidated financial position or results of operations. In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. This update also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment at each reporting period. ASU 2016-01 is effective for fiscal years, and interim periods within, beginning after December 15, 2017. Early adoption is permitted only for updates to certain disclosure requirements. The Company is evaluating the impact of the adoption of ASU 2016-01 on January 1, 2018 to its consolidated financial position or results of operations. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by requiring the acquirer to (i) recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined, (ii) record, in the same period, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date and (iii) present separately or disclose the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective for fiscal years, and interim periods within, beginning after December 15, 2015. Early adoption is permitted. The Company adopted ASU 2015-16 on January 1, 2016; the adoption of which did not have a material impact on its consolidated financial position or results of operations. In February 2015, the FASB issued ASU No. 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 requires amendments to both the VIE and voting consolidation accounting models. The amendments (i) rescind the indefinite deferral of certain aspects of accounting standards relating to consolidations and provide a permanent scope exception for registered money market funds and similar unregistered money market funds, (ii) modify (a) the identification of variable interests (fees paid to a decision maker or service provider), (b) the VIE characteristics for a limited partnership or similar entity and (c) the primary beneficiary determination under the VIE model and (iii) eliminate the presumption within the current voting model that a general partner controls a limited partnership or similar entity. ASU 2015-02 is effective for fiscal years, and interim periods within, beginning after December 15, 2015. Early adoption is permitted. A reporting entity may apply the amendments in ASU 2015-02 using either a modified retrospective or retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. The Company adopted ASU 2015-02 on January 1, 2016; the adoption of which did not have a material impact to its consolidated financial position or results of operations (see Note 16). In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). This update changes the requirements for recognizing revenue. ASU 2014-09 provides guidance for revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”). ASU 2015-14 defers the effective date of ASU 2014-09 by one year to fiscal years, and interim periods within, beginning after December 15, 2017. Early adoption is permitted for annual periods, and interim periods within, beginning after December 15, 2016. A reporting entity may apply the amendments in ASU 2014-09 using either a modified retrospective or retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. The Company is evaluating the impact of the adoption of ASU 2014-09 on January 1, 2018 to its consolidated financial position or results of operations.
Reclassifications	Reclassification Certain amounts in the Company’s consolidated financial statements have been reclassified for prior periods to conform to the current period presentation.
