Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Description of Business	1. Organization and Description of Business Griffin-American Healthcare REIT III, Inc., a Maryland corporation, was incorporated on January 11, 2013 and therefore we consider that our date of inception. We were initially capitalized on January 15, 2013 . We invest in a diversified portfolio of real estate properties, focusing primarily on medical office buildings, hospitals, skilled nursing facilities, senior housing and other healthcare-related facilities. We also operate healthcare-related facilities utilizing the structure permitted by the REIT Investment Diversification and Empowerment Act of 2007, which is commonly referred to as a “RIDEA” structure (the provisions of the Internal Revenue Code of 1986, as amended, or the Code, authorizing the RIDEA structure were enacted as part of the Housing and Economic Recovery Act of 2008). We also originate and acquire secured loans and real estate-related investments on an infrequent and opportunistic basis. We generally seek investments that produce current income. We qualified to be taxed as a real estate investment trust, or REIT, under the Code, for federal income tax purposes beginning with our taxable year ended December 31, 2014 , and we intend to continue to qualify to be taxed as a REIT. On February 26, 2014, we commenced a best efforts initial public offering, or our initial offering, in which we initially offered to the public up to $1,750,000,000 in shares of our common stock for $10.00 per share in our primary offering and up to $150,000,000 in shares of our common stock pursuant to our distribution reinvestment plan, or the DRIP, for $9.50 per share, aggregating up to $1,900,000,000 . We reserved the right to reallocate the shares of common stock we offered in our initial offering between the primary offering and the DRIP. As such, during our initial offering, we reallocated an aggregate of $115,000,000 in shares from the DRIP to the primary offering. Accordingly, we offered to the public up to $1,865,000,000 in shares of our common stock in our primary offering and up to $35,000,000 in shares of our common stock pursuant to the DRIP. On March 12, 2015, we terminated the primary portion of our initial offering. We continued to offer up to $35,000,000 in shares of our common stock through our initial offering pursuant to the DRIP until the termination of the DRIP portion of our initial offering and deregistration of our initial offering on April 22, 2015. As of April 22, 2015, we had received and accepted subscriptions in our initial offering for 184,930,598 shares of our common stock, or $1,842,618,000 , excluding shares of our common stock issued pursuant to the DRIP. As of April 22, 2015, a total of $18,511,000 in distributions were reinvested that resulted in 1,948,563 shares of our common stock being issued pursuant to the DRIP. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, or the Securities Act, to register a maximum of $250,000,000 of additional shares of our common stock pursuant to our distribution reinvestment plan, or the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the United States Securities and Exchange Commission, or the SEC, upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, we amended and restated the DRIP, or the Amended and Restated DRIP, to amend the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. See Note 21, Subsequent Events — Amended and Restated Distribution Reinvestment Plan Price, for a further discussion. As of September 30, 2016 , a total of $92,250,000 in distributions were reinvested and 9,709,538 shares of our common stock were issued pursuant to the Secondary DRIP Offering. We conduct substantially all of our operations through Griffin-Am erican Healthcare REIT III Holdings, LP, or our operating partnership.

Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and of which we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf. We are the sole general partner of o ur operating partnership and as of September 30, 2016 and December 31, 2015 , we owned greater than a 99.99% general partnership interest therein. As of September 30, 2016 and December 31, 2015 , our advisor owned less than a 0.01% limited partnership interest in our operating partnership. Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation. 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 view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2015 Annual Report on Form 10-K, as filed with the SEC on March 30, 2016. Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions. Allowance for Uncollectible Accounts Tenant and resident receivables and unbilled deferred rent receivables are carried net of an allowance for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants or residents to meet the contractual obligations under their lease agreements. We also maintain an allowance for deferred rent receivables arising from the straight-line recognition of rents. Such allowances are charged to bad debt expense, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s or resident’s financial condition, security deposits, letters of credit, lease guarantees, current economic conditions and other relevant factors. As of September 30, 2016 and December 31, 2015 , we had $10,409,000 and $11,204,000 , respectively, in allowance for uncollectible accounts, which was determined necessary to reduce receivables to our estimate of the amount recoverable. For the three and nine months ended September 30, 2016 and 2015 , we did not write off any receivables to bad debt expense. For the three and nine months ended September 30, 2016 , $1,467,000 and $4,059,000 , respectively, of our receivables were written off against the allowance for uncollectible accounts. For the three and nine months ended September 30, 2015 , we did not write off any receivables against the allowance for uncollectible accounts. As of September 30, 2016 and December 31, 2015 , we did not have any allowance for uncollectible accounts for deferred rent receivables. For the three months ended September 30, 2016 and 2015 , we did not write off any of our deferred rent receivables directly to bad debt expense. For the nine months ended September 30, 2016 and 2015 , $28,000 and $0 , respectively, of our deferred rent receivables were directly written off to bad debt expense. Accounts Payable and Accrued Liabilities As of September 30, 2016 and December 31, 2015 , accounts payable and accrued liabilities consisted primarily of reimbursement of payroll related costs to the managers of our senior housing — RIDEA facilities and integrated senior health campuses of $18,521,000 and $19,391,000 , respectively, insurance payables of $17,277,000 and $21,689,000 , respectively, accrued property taxes of $14,739,000 and $11,447,000 , respectively, and accrued distributions of $9,647,000 and $9,745,000 , respectively. Derivative Financial Instruments We are exposed to the effect of interest rate changes in the normal course of business. We seek to mitigate these risks by following established risk management policies and procedures, which include the occasional use of derivatives. Our primary strategy in entering into derivative contracts, such as fixed interest rate swaps and interest rate caps, is to add stability to interest expense and to manage our exposure to interest rate movements by effectively converting a portion of our variable-rate debt to fixed-rate debt. We do not enter into derivative instruments for speculative purposes. Derivatives are recognized as either assets or liabilities in our accompanying condensed consolidated balance sheets and are measured at fair value in accordance with ASC Topic 815, Derivatives and Hedging , or ASC Topic 815. ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. Since our derivative instruments are not designated as hedge instruments, they do not qualify for hedge accounting under ASC Topic 815. Changes in the fair value of interest rate derivative financial instruments are recorded as a component of interest expense in gain (loss) in fair value of derivative financial instruments in our accompanying condensed consolidated statements of operations and comprehensive loss. See Note 9, Derivative Financial Instruments , and Note 15, Fair Value Measurements , for a further discussion of our derivative financial instruments. Reclassifications As of December 31, 2015, $1,200,000 of deferred financing costs, net, related to our mortgage loans payable have been reclassified from other assets, net to mortgage loans payable, net in our accompanying condensed consolidated balance sheets to conform to the current period presentation in accordance with Accounting Standards Update, or ASU, 2015-03, Simplifying the Presentation of Debt Issuance Costs, or ASU 2015-03. Such reclassification did not have a material impact on our consolidated financial statements. Recently Issued or Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, or ASU 2014-09, which replaces the existing accounting standards for revenue recognition. ASU 2014-09 provides a five-step framework to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration expected to be received in exchange for those goods or services. Since its issuance, the FASB has amended several aspects of ASU 2014-09, including provisions that address principal-versus-agent implementation guidance and identifying performance obligations. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. It may be adopted either by restating all years presented in the financial statements or by recording the impact of adoption as an adjustment to retained earnings at the beginning of the year of adoption. We have not yet selected a transition method nor have we determined the impact the adoption of ASU 2014-09 and its amendments on January 1, 2018 will have on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, or ASU 2015-02, which amends the consolidation analysis required under ASC Topic 810. Specifically, ASU 2015-02: (i) modifies the evaluation of whether limited partnerships and similar legal entities are VIEs; (ii) eliminates the presumption that a general partner should consolidate a limited partnership; and (iii) amends the effect of fee arrangements in the primary beneficiary determination. Further, the application of ASU 2015-02 permits the use of either the full retrospective or modified retrospective adoption approach. ASU 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015 with early adoption permitted. We adopted ASU 2015-02 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs , or ASU 2015-03, which amends the presentation of debt issuance costs in the financial statements to present such costs as a direct deduction from the carrying amount of the related debt liability rather than as an asset. Amortization of such costs is required to be reported as interest expense. In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , or ASU 2015-15, which clarified that debt issuance costs associated with line of credit arrangements may continue to be presented as an asset, regardless of whether there are any outstanding borrowings on the line of credit arrangement. The application of ASU 2015-03 requires retrospective adjustment of all prior periods presented. ASU 2015-03 is effective for interim and annual reporting periods beginning after December 15, 2015 with early adoption permitted. We adopted ASU 2015-03 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, or ASU 2015-16, which eliminates the requirement to restate prior period financial statements for measurement period adjustments in a business combination. The cumulative effect of a measurement period adjustment as a result of a change in the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, is required to be recorded in the reporting period in which the adjustment amount is determined, rather than retrospectively. Further, ASU 2015-16 requires that the acquirer present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in the 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 interim and annual reporting periods beginning after December 15, 2015 and should be applied prospectively to adjustments to provisional amounts that occur after the effective date. Early adoption is permitted for financial statements that have not yet been made available for issuance. We adopted ASU 2015-16 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01, which amends the classification and measurement of financial instruments. ASU 2016-01 revises the accounting related to: (i) the classification and measurement of investments in equity securities; and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, with respect to only certain of the amendments in ASU 2016-01, for financial statements that have not yet been made available for issuance. ASU 2016-01 requires the application of the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with certain exceptions. We have not yet determined the impact the adoption of ASU 2016-01 on January 1, 2018 will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , or ASU 2016-02, which amends the guidance on accounting for leases, including extensive amendments to the disclosure requirements. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU 2016-02, lessor accounting is largely unchanged. ASU 2016-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted for financial statements that have not yet been made available for issuance. ASU 2016-02 requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We have not yet determined the impact the adoption of ASU 2016-02 on January 1, 2019 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, or ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 requires disclosures about a change in accounting principle under ASC 250, Accounting Changes and Error Corrections , in the period of adoption. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016. Early adoption is permitted for financial statements that have not yet been made available for issuance. We do not expect the adoption of ASU 2016-09 on January 1, 2017 to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We have not yet determined the impact the adoption of ASU 2016-13 on January 1, 2020 will have on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15, which intends to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We have not yet determined the impact the adoption of ASU 2016-15 on January 1, 2018 will have on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, or ASU 2016-16, which removes the prohibition in ASC 740, Income Taxes , against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We have not yet determined the impact the adoption of ASU 2016-16 on January 1, 2018 will have on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control , or ASU 2016-17, which amends the consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a VIE. ASU 2016-17 is effective for annual periods beginning on or after December 15, 2016. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-17 on December 15, 2016 to have a material impact on our consolidated financial statements.

The acquisition of the development parcel with improvements in Kentucky was financed with a mortgage loan payable, which had a principal balance of $2,040,000 at the time of acquisition. We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets. The reimbursement of acquisition expenses, acquisition fees and real estate commissions and other fees paid to unaffiliated parties will not exceed, in the aggregate, 6.0% of the contract purchase price or total development costs, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors.

The mezzanine loan is secured by pledges of equity interests in the owners of a portfolio of domestic healthcare properties, which such owners are themselves owned indirectly by a non-wholly owned subsidiary of NorthStar Realty Finance Corp. The maturity date of the Mezzanine Floating Rate Notes may be extended by three successive one -year extension periods at the borrower’s option, subject to satisfaction of certain conditions. In October 2016, the borrower exercised its right to extend the maturity date of the Mezzanine Floating Rate Notes for one year to December 2017. (4) We entered into a facility agreement with Caring Homes (TFP) Group Limited, or the CHG Borrower, an unaffiliated third party, on September 16, 2015. The facility agreement, as amended, matures on November 15, 2016. The facility agreement, as amended, is collateralized by two senior housing facilities in the United Kingdom, or the UK, and the income from the CHG Borrower’s operations. Based on the currency exchange rate as of September 30, 2016 , the maximum amount of advances available was £16,000,000 , or approximately $20,750,000 , and the outstanding balance as of September 30, 2016 was £15,276,000 , or approximately $19,812,000 . Based on the currency exchange rate as of September 30, 2016 , approximately $938,000 remained available for future funding under Crown Senior Care Facility, subject to certain conditions set forth in the applicable loan agreement, as amended. As of September 30, 2016 , the CHG Borrower has been identified as a VIE. We do not consolidate such VIE because we do not have the ability to control the activities that most significantly impact the VIE’s economic performance. Our exposure to loss as a result of involvement with such VIE is limited to the outstanding balance of Crown Senior Care Facility. (5) Balance represents the original principal balance, increased by any subsequent advances and decreased by any subsequent principal paydowns, and only requires monthly interest payments. The Mezzanine Floating Rate Notes, Mezzanine Fixed Rate Notes and Crown Senior Care Facility are subject to certain prepayment restrictions if repaid before the respective maturity dates. (6) On October 15, 2015, we acquired a commercial mortgage-backed debt security, or the debt security, for a purchase price of $60,429,000 from an unaffiliated third party. The debt security was issued by FREMF 2015-KS03 Mortgage Trust, or the Mortgage Trust, and represents a 10.0% beneficial ownership interest in the Mortgage Trust. The Mortgage Trust owns a pool of 59 mortgage loans that are secured by 59 domestic senior housing facilities. The debt security bears an interest rate on the stated principal amount thereof equal to 4.24% per annum, the terms of which security provide for monthly interest-only payments. The debt security matures on August 25, 2025 at a stated amount of $93,433,000 , resulting in an anticipated yield-to-maturity of 10.0% per annum. The debt security is subordinate to all other interests in the Mortgage Trust and is not guaranteed by a government-sponsored entity. We classify our debt security investment as held-to-maturity and we have not recorded any unrealized holding gains or losses on such investment. We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets. The reimbursement of acquisition expenses, acquisition fees, real estate commissions and other fees paid to unaffiliated parties will not exceed, in the aggregate, 6.0% of the contract purchase price or total development costs, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors. For the three and nine months ended September 30, 2016 and 2015 , such fees and expenses noted above did not exceed 6.0% of the contract purchase price of our real estate-related investments. The changes in the carrying amount of real estate notes receivable and debt security investment, net consisted of the following for the nine months ended September 30, 2016 and 2015 : Nine Months Ended September 30, 2016 2015 Beginning balance $ 144,477,000 $ — Additions: Acquisition of real estate notes receivable 1,942,000 81,805,000 Accretion on debt security investment 1,650,000 — Loan costs 39,000 1,705,000 Deductions: Foreign currency translation adjustments (2,892,000 ) (342,000 ) Amortization of loan and closing costs (607,000 ) (333,000 ) Ending balance $ 144,609,000 $ 82,835,000 For the three and nine months ended September 30, 2016 and 2015 , we did not record any impairment losses on our real estate notes receivable and debt security investment.

The unused fee is payable monthly in arrears, commencing on the first day of each month from and after the closing date up to the first day of the month prior to the date on which the obligations are paid in full. If the commitment is terminated prior to the second anniversary of the closing date, a prepayment premium of 1.00% of the total commitment applies. The Trilogy OpCo Credit Agreement, as amended, contains customary events of default, covenants and other terms, including, among other things, restrictions on the payment of dividends and other distributions, incurrence of indebtedness, creation of liens and transactions with affiliates. Availability of the total commitment under the Trilogy OpCo Line of Credit is subject to a borrowing base based on, among other things, the eligible accounts receivable outstanding of the Trilogy OpCo Borrowers. Our aggregate borrowing capacity under the Trilogy OpCo Line of Credit was $60,000,000 as of September 30, 2016 , subject to certain terms and conditions. As of September 30, 2016 , borrowings outstanding under the Trilogy OpCo Line of Credit totaled $16,484,000 , and $43,516,000 remained available.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure	9. Derivative Financial Instruments Consistent with ASC Topic 815, we record derivative financial instruments in our accompanying condensed consolidated balance sheets as either an asset or a liability measured at fair value. ASC Topic 815 permits special hedge accounting if certain requirements are met. Hedge accounting allows for gains and losses on derivatives designated as hedges to be offset by the change in value of the hedged item or items or to be deferred in other comprehensive income (loss). We did not have any derivative financial instruments as of December 31, 2015 . The following table lists the derivative financial instruments held by us as of September 30, 2016 : Notional Amount Index Interest Rate Fair Value Instrument Maturity Date $ 17,075,000 one month LIBOR 2.25 % $ — Cap 02/01/18 140,000,000 one month LIBOR 0.82 % (64,000 ) Swap 02/03/19 60,000,000 one month LIBOR 0.78 % 25,000 Swap 02/03/19 $ 217,075,000 $ (39,000 ) As of September 30, 2016 , none of our derivatives were designated as hedges. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements, but do not meet the strict hedge accounting requirements of ASC Topic 815. Changes in the fair value of derivative financial instruments are recorded as a component of interest expense in gain (loss) in fair value of derivative financial instruments in our accompanying condensed consolidated statements of operations and comprehensive loss. For the three and nine months ended September 30, 2015 , we did not have any derivative financial instruments. For the three and nine months ended September 30, 2016 , we recorded a decrease (increase) of $989,000 and $(54,000) , respectively, to interest expense in our accompanying condensed consolidated statements of operations and comprehensive loss related to the change in the fair value of our derivative financial instruments. See Note 15, Fair Value Measurements , for a further discussion of the fair value of our derivative financial instruments.

On March 12, 2015, we terminated the primary portion of our initial offering. We continued to offer shares of our common stock in our initial offering pursuant to the DRIP, until the termination of the DRIP portion of our initial offering and deregistration of our initial offering on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering.

Offering Costs Selling Commissions Through the termination of the primary portion of our initial offering on March 12, 2015, we paid our dealer manager selling commissions of up to 7.0% of the gross offering proceeds from the sale of shares of our common stock in our initial offering other than shares of our common stock sold pursuant to the DRIP. Our dealer manager was permitted to re-allow all or a portion of these fees to participating broker-dealers. For the three and nine months ended September 30, 2015 , we incurred $0 and $62,362,000 , respectively, in selling commissions to our dealer manager. Such commissions were charged to stockholders’ equity as such amounts were paid to our dealer manager from the gross proceeds of our initial offering. Dealer Manager Fee Through the termination of the primary portion of our initial offering on March 12, 2015, we paid our dealer manager a dealer manager fee of up to 3.0% of the gross offering proceeds from the sale of shares of our common stock in our initial offering other than shares of our common stock sold pursuant to the DRIP. For the three and nine months ended September 30, 2015 , we incurred $0 and $27,789,000 , respectively, in dealer manager fees to our dealer manager. Such fees were charged to stockholders’ equity as such amounts were paid to our dealer manager or its affiliates from the gross proceeds of our initial offering. Accumulated Other Comprehensive Loss The changes in accumulated other comprehensive loss, net of noncontrolling interests, by component consisted of the following for the nine months ended September 30, 2016 and 2015 : Nine Months Ended September 30, 2016 2015 Beginning balance — foreign currency translation adjustments $ (506,000 ) $ — Net change in current period (1,916,000 ) (160,000 ) Ending balance — foreign currency translation adjustments $ (2,422,000 ) $ (160,000 ) Noncontrolling Interests On December 1, 2015, we, through Trilogy REIT Holdings, completed the acquisition of approximately 96.7% of the outstanding equity interests of Trilogy. As of September 30, 2016 , Trilogy REIT Holdings owned approximately 96.7% of Trilogy. We are the indirect owner of a 70.0% interest in Trilogy REIT Holdings and serve as the sole manager of Trilogy REIT Holdings. NorthStar Healthcare Income, Inc., through certain of its subsidiaries, owns a 30.0% ownership interest in Trilogy REIT Holdings. As of September 30, 2016 and December 31, 2015 , 30.0% of the net earnings of Trilogy REIT Holdings were allocated to noncontrolling interests. In connection with the acquisition and operation of Trilogy, profit interest units in Trilogy, or the Profit Interests, were issued to Trilogy Management Services, LLC and an independent director of Trilogy, both are unaffiliated third parties that manage or direct the day-to day operations of Trilogy. The Profit Interests consist of time-based or performance-based commitments. The time-based Profit Interests were measured at their grant date fair value and vest in increments of 20.0% on each anniversary of the respective grant date over a five -year period. We amortize the time-based Profit Interests on a straight-line basis over the vesting periods, which are recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. The performance-based Profit Interests are subject to a performance commitment and vest upon liquidity events as defined in the Profit Interests agreements. The performance-based Profit Interests were measured at their grant date fair value and immediately expensed. The performance-based Profit Interests will be subject to fair value measurements until vesting occurs with changes to fair value recorded to general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. For the three and nine months ended September 30, 2016 , we recognized stock compensation expense related to the Profit Interests of $196,000 and $589,000 , respectively. There were no canceled, expired or exercised Profit Interests during the three and nine months ended September 30, 2016 . As of September 30, 2016 and December 31, 2015 , no Profit Interests were vested. The nonvested awards are presented as noncontrolling interests and will be re-classified to redeemable noncontrolling interests upon vesting as they have redemption features outside of our control similar to the common units held by Trilogy’s pre-closing management once vested. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. On January 6, 2016, one of our consolidated subsidiaries issued non-voting preferred shares of beneficial interests to qualified investors for total proceeds of $125,000 . These preferred shares of beneficial interests are entitled to receive cumulative preferential cash dividends at the rate of 12.5% per annum. In accordance with ASC Topic 810, we classify the value of the subsidiary’s preferred shares of beneficial interests as noncontrolling interests in our accompanying condensed consolidated balance sheets and the dividends of the preferred shares of beneficial interests as net loss attributable to noncontrolling interests in our accompanying condensed consolidated statements of operations and comprehensive loss. In addition, as of September 30, 2016 , we owned an 86.0% interest in a consolidated limited liability company that owns the Lakeview IN Medical Plaza property we acquired on January 21, 2016. As such, 14.0% of the earnings of the Lakeview IN Medical Plaza property were allocated to noncontrolling interests for the three and nine months ended September 30, 2016 . Distribution Reinvestment Plan We adopted the DRIP that allowed stockholders to purchase additional shares of our common stock through the reinvestment of distributions at an offering price equal to 95.0% of the primary offering price of our initial offering, subject to certain conditions. We had registered and reserved $35,000,000 in shares of our common stock for sale pursuant to the DRIP in our initial offering at an offering price of $9.50 per share, which we terminated on April 22, 2015. On March 25, 2015, we filed a Registration Statement on Form S-3 under the Securities Act to register a maximum of $250,000,000 of additional shares of our common stock pursuant to the Secondary DRIP Offering. The Registration Statement on Form S-3 was automatically effective with the SEC upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP Offering until April 22, 2015, following the deregistration of our initial offering. Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock are issued pursuant to the Secondary DRIP Offering. See Note 21, Subsequent Events — Amended and Restated Distribution Reinvestment Plan Price, for a further discussion. For the three months ended September 30, 2016 and 2015 , $16,199,000 and $16,441,000 , respectively, in distributions were reinvested that resulted in 1,705,192 and 1,730,648 shares of our common stock, respectively, being issued pursuant to the DRIP and the Secondary DRIP Offering. For the nine months ended September 30, 2016 and 2015 , $48,692,000 and $43,087,000 , respectively, in distributions were reinvested that resulted in 5,124,834 and 4,535,536 shares of our common stock, respectively, being issued pursuant to the DRIP and the Secondary DRIP Offering.

Share Repurchase Plan Our board has approved a share repurchase plan. Our share repurchase plan allows for repurchases of shares of our common stock by us when certain criteria are met. Share repurchases will be made at the sole discretion of our board. Subject to the availability of the funds for share repurchases, we will limit the number of shares of our common stock repurchased during any calendar year to 5.0% of the weighted average number of shares of our common stock outstanding during the prior calendar year; provided, however, that shares subject to a repurchase requested upon the death of a stockholder will not be subject to this cap. Funds for the repurchase of shares of our common stock will come exclusively from the cumulative proceeds we receive from the sale of shares of our common stock pursuant to the DRIP and the Secondary DRIP Offering. All repurchases will be subject to a one -year holding period, except for repurchases made in connection with a stockholder’s death or “qualifying disability,” as defined in our share repurchase plan. Further, all share repurchases will be repurchased following a one -year holding period at a price between 92.5% and 100% of each stockholder’s repurchase amount, depending on the period of time their shares have been held. Until October 4, 2016, the repurchase amount for shares repurchased under our share repurchase plan was equal to or lower than the most recent per share offering price. However, if shares of our common stock were repurchased in connection with a stockholder’s death or qualifying disability, the repurchase price was no less than 100% of the price paid to acquire the shares of our common stock from us. Effective October 5, 2016, we amended the price at which shares of our common stock are repurchased pursuant to our amended and restated share repurchase plan, or Amended and Restated Share Repurchase Plan. See Note 21, Subsequent Events — Amended and Restated Share Repurchase Plan, for a further discussion. Furthermore, our share repurchase plan provides that if there are insufficient funds to honor all repurchase requests, pending requests will be honored among all requests for repurchase in any given repurchase period as follows: first, pro rata as to repurchases sought upon a stockholder’s death; next, pro rata as to repurchases sought by stockholders with a qualifying disability; and, finally, pro rata as to other repurchase requests. For the three months ended September 30, 2016 and 2015 , we received share repurchase requests and repurchased 933,974 and 205,910 shares of our common stock, respectively, for an aggregate of $8,835,000 and $2,043,000 , respectively, at an average repurchase price of $9.46 and $9.92 per share, respectively. For the nine months ended September 30, 2016 and 2015 , we received share repurchase requests and repurchased 1,564,814 and 286,720 shares of our common stock, respectively, for an aggregate of $14,833,000 and $2,846,000 , respectively, at an average repurchase price of $9.48 and $9.93 per share, respectively. As of September 30, 2016 and December 31, 2015 , we received share repurchase requests and repurchased 1,945,743 and 380,929 shares of our common stock, respectively, for an aggregate of $18,594,000 and $3,761,000 , respectively, at an average price of $9.56 and $9.87 per share, respectively. All shares were repurchased using proceeds we received from the sale of shares of our common stock pursuant to the DRIP and the Secondary DRIP Offering. 2013 Incentive Plan We adopted the 2013 Incentive Plan, or our incentive plan, pursuant to which our board or a committee of our independent directors may make grants of options, shares of restricted common stock, stock purchase rights, stock appreciation rights or other awards to our independent directors, employees and consultants. The maximum number of shares of our common stock that may be issued pursuant to our incentive plan is 2,000,000 shares. Through September 30, 2016 , we granted an aggregate of 30,000 shares of our restricted common stock, as defined in our incentive plan, to our independent directors in connection with their initial election or re-election to our board, of which 20.0% vested on the grant date and 20.0% will vest on each of the first four anniversaries of the grant date. In addition, through September 30, 2016 , we granted an aggregate of 30,000 shares of our restricted common stock, as defined in our incentive plan, to our independent directors in consideration for their past services rendered. These shares of restricted common stock vest under the same period described above. Shares of our restricted common stock may not be sold, transferred, exchanged, assigned, pledged, hypothecated or otherwise encumbered. Such restrictions expire upon vesting. Shares of our restricted common stock have full voting rights and rights to distributions. From the applicable dates that the required service periods began, or the service inception dates, to the applicable grant dates, we recognized compensation expense related to the shares of our restricted common stock based on the reporting date fair value, which was estimated at $10.00 per share, the then most recent price paid to acquire a share of common stock in our initial offering. Beginning on the applicable grant dates, compensation cost related to the shares of our restricted common stock is measured based on the applicable grant date fair value, which we estimated at $10.00 per share, the then most recent price paid to acquire a share of common stock in our initial offering. Stock compensation expense is recognized from the applicable service inception dates to the vesting date for each vesting tranche (i.e., on a tranche-by-tranche basis) using the accelerated attribution method. ASC Topic 718, Compensation — Stock Compensation, requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For the three and nine months ended September 30, 2016 and 2015 , we did not assume any forfeitures. For the three months ended September 30, 2016 and 2015 , we recognized compensation expense related to the director grants of $90,000 and $33,000 , respectively, and for the nine months ended September 30, 2016 and 2015 , we recognized compensation expense related to the director grants of $151,000 and $83,000 , respectively, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. As of September 30, 2016 and December 31, 2015 , there was $278,000 and $129,000 , respectively, of total unrecognized compensation expense, net of estimated forfeitures, related to nonvested shares of our restricted common stock. As of September 30, 2016 , this expense is expected to be recognized over a remaining weighted average period of 1.93 years. As of September 30, 2016 and December 31, 2015 , the weighted average grant date fair value of the nonvested shares of our restricted common stock was $400,000 and $210,000 , respectively. A summary of the status of the nonvested shares of our restricted common stock as of September 30, 2016 and December 31, 2015 and the changes for the nine months ended September 30, 2016 , is presented below: Number of Nonvested Shares of our Restricted Common Stock Weighted Average Grant Date Fair Value Balance — December 31, 2015 21,000 $ 10.00 Granted 30,000 $ 10.00 Vested (11,000 ) $ 10.00 Forfeited — $ — Balance — September 30, 2016 40,000 $ 10.00 Expected to vest — September 30, 2016 40,000 $ 10.00

Development Fee In the event our advisor or its affiliates provide development-related services, we pay our advisor or its affiliates a development fee in an amount that is usual and customary for comparable services rendered for similar projects in the geographic market where the services are provided; however, we will not pay a development fee to our advisor or its affiliates if our advisor or its affiliates elect to receive an acquisition fee based on the cost of such development. For the three and nine months ended September 30, 2016 , we incurred $76,000 in development fees to our advisor or its affiliates. For the three and nine months ended September 30, 2015 , we did not incur any development fees to our advisor or its affiliates. Development fees are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. Reimbursement of Acquisition Expenses We reimburse our advisor or its affiliates for acquisition expenses related to selecting, evaluating and acquiring assets, which are reimbursed regardless of whether an asset is acquired. The reimbursement of acquisition expenses, acquisition fees and real estate commissions paid to unaffiliated parties will not exceed, in the aggregate, 6.0% of the contract purchase price or total development costs, unless fees in excess of such limits are approved by a majority of our directors, including a majority of our independent directors, not otherwise interested in the transaction. For the three and nine months ended September 30, 2016 and 2015 , such fees and expenses did not exceed 6.0% of the contract purchase price of our acquisitions, except with respect to our acquisition of Crown Senior Care Portfolio on September 15, 2015. For further discussion, please see Note 3, Real Estate Investments, Net . Reimbursements of acquisition expenses are expensed as incurred in accordance with ASC Topic 805 and included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. Reimbursements of acquisition expenses in connection with the acquisition of real estate-related investments are capitalized as part of the associated investment in our accompanying condensed consolidated balance sheets. For the three and nine months ended September 30, 2016 , we incurred $1,000 in acquisition expenses to our advisor or its affiliates. For the three and nine months ended September 30, 2015 , we incurred $0 and $30,000 , respectively, in acquisition expenses to our advisor or its affiliates. Operational Stage Asset Management Fee We pay our advisor or its affiliates a monthly fee for services rendered in connection with the management of our assets equal to one-twelfth of 0.75% of average invested assets, subject to our stockholders receiving distributions in an amount equal to 5.0% per annum, cumulative, non-compounded, of invested capital. For such purposes, average invested assets means the average of the aggregate book value of our assets invested in real estate properties and real estate-related investments, before deducting depreciation, amortization, bad debt and other similar non-cash reserves, computed by taking the average of such values at the end of each month during the period of calculation; and invested capital means, for a specified period, the aggregate issue price of shares of our common stock purchased by our stockholders, reduced by distributions of net sales proceeds by us to our stockholders and by any amounts paid by us to repurchase shares of our common stock pursuant to our share repurchase plan. For the three months ended September 30, 2016 and 2015 , we incurred $4,427,000 and $1,912,000 , respectively, and for the nine months ended September 30, 2016 and 2015 , we incurred $12,373,000 and $4,286,000 , respectively, in asset management fees to our advisor or its affiliates. Asset management fees are included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. Property Management Fee Our advisor or its affiliates may directly serve as property manager of our properties or may sub-contract their property management duties to any third party and provide oversight of such third-party property manager. We pay our advisor or its affiliates a monthly management fee equal to a percentage of the gross monthly cash receipts of such property as follows: (i) a 1.0% property management oversight fee for any stand-alone, single-tenant, net leased property; (ii) a 1.5% property management oversight fee for any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates will provide oversight of a third party that performs the duties of a property manager with respect to such property; or (iii) a fair and reasonable property management fee that is approved by a majority of our directors, including a majority of our independent directors, that is not less favorable to us than terms available from unaffiliated third parties for any property that is not a stand-alone, single-tenant, net leased property and for which our advisor or its affiliates will directly serve as the property manager without sub-contracting such duties to a third party. For the three months ended September 30, 2016 and 2015 , we incurred $517,000 and $198,000 , respectively, and for the nine months ended September 30, 2016 and 2015 , we incurred $1,752,000 and $509,000 , respectively, in property management fees to our advisor or its affiliates. Property management fees are included in property operating expenses and rental expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. Lease Fees We pay our advisor or its affiliates a separate fee for any leasing activities in an amount not to exceed the fee customarily charged in arm’s-length transactions by others rendering similar services in the same geographic area for similar properties as determined by a survey of brokers and agents in such area. Such fee is generally expected to range from 3.0% to 6.0% of the gross revenues generated during the initial term of the lease. For the three months ended September 30, 2016 and 2015 , we incurred $45,000 and $10,000 , respectively, and for the nine months ended September 30, 2016 and 2015 , we incurred $140,000 and $22,000 , respectively, in lease fees to our advisor or its affiliates. Lease fees are capitalized as lease commissions and included in other assets, net in our accompanying condensed consolidated balance sheets. Construction Management Fee In the event that our advisor or its affiliates assist with planning and coordinating the construction of any capital or tenant improvements, we pay our advisor or its affiliates a construction management fee of up to 5.0% of the cost of such improvements. For the three and nine months ended September 30, 2016 , we incurred $21,000 and $22,000 , respectively, in construction management fees to our advisor or its affiliates. For the three and nine months ended September 30, 2015 , we incurred $2,000 in construction management fees to our advisor or its affiliates. Construction management fees are capitalized as part of the associated asset and included in real estate investments, net in our accompanying condensed consolidated balance sheets or will be expensed and included in our accompanying condensed consolidated statements of operations and comprehensive loss, as applicable. Operating Expenses We reimburse our advisor or its affiliates for operating expenses incurred in rendering services to us, subject to certain limitations. However, we cannot reimburse our advisor or its affiliates at the end of any fiscal quarter for total operating expenses that, in the four consecutive fiscal quarters then ended, exceed the greater of: (i) 2.0% of our average invested assets, as defined in the Advisory Agreement; or (ii) 25.0% of our net income, as defined in the Advisory Agreement, unless our independent directors determined that such excess expenses were justified based on unusual and nonrecurring factors which they deem sufficient. Our operating expenses as a percentage of average invested assets and as a percentage of net income were 1.0% and 22.6% , respectively, for the 12 months ended September 30, 2016 ; however, we did not exceed the aforementioned limitation as 2.0% of our average invested assets was greater than 25.0% of our net income. For the three months ended September 30, 2016 and 2015 , our advisor or its affiliates incurred operating expenses on our behalf of $31,000 and $11,000 , respectively, and for the nine months ended September 30, 2016 and 2015 , our advisor or its affiliates incurred operating expenses on our behalf of $53,000 and $25,000 , respectively. Operating expenses are generally included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. Compensation for Additional Services We pay our advisor and its affiliates for services performed for us other than those required to be rendered by our advisor or its affiliates under the Advisory Agreement. The rate of compensation for these services has to be approved by a majority of our board, including a majority of our independent directors, and cannot exceed an amount that would be paid to unaffiliated parties for similar services. For the three and nine months ended September 30, 2016 and 2015 , our advisor and its affiliates were not compensated for any additional services. Liquidity Stage Disposition Fees For services relating to the sale of one or more properties, we pay our advisor or its affiliates a disposition fee up to the lesser of 2.0% of the contract sales price or 50.0% of a customary competitive real estate commission given the circumstances surrounding the sale, in each case as determined by our board, including a majority of our independent directors, upon the provision of a substantial amount of the services in the sales effort. The amount of disposition fees paid, when added to the real estate commissions paid to unaffiliated parties, will not exceed the lesser of the customary competitive real estate commission or an amount equal to 6.0% of the contract sales price. For the three and nine months ended September 30, 2016 and 2015 , we did not incur any disposition fees to our advisor or its affiliates. Subordinated Participation Interest Subordinated Distribution of Net Sales Proceeds In the event of liquidation, we will pay our advisor a subordinated distribution of net sales proceeds. The distribution will be equal to 15.0% of the remaining net proceeds from the sales of properties, after distributions to our stockholders, in the aggregate, of: (i) a full return of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan); plus (ii) an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock, as adjusted for distributions of net sales proceeds. Actual amounts to be received depend on the sale prices of properties upon liquidation. For the three and nine months ended September 30, 2016 and 2015 , we did not pay any such distributions to our advisor. Subordinated Distribution Upon Listing Upon the listing of shares of our common stock on a national securities exchange, in redemption of our advisor’s limited partnership units, we will pay our advisor a distribution equal to 15.0% of the amount by which: (i) the market value of our outstanding common stock at listing plus distributions paid prior to listing exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the amount of cash that, if distributed to stockholders as of the date of listing, would have provided them an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the date of listing. Actual amounts to be paid depend upon the market value of our outstanding stock at the time of listing, among other factors. For the three and nine months ended September 30, 2016 and 2015 , we did not pay any such distributions to our advisor. Subordinated Distribution Upon Termination Pursuant to the Agreement of Limited Partnership, as amended, of our operating partnership, upon termination or non-renewal of the Advisory Agreement, our advisor will also be entitled to a subordinated distribution in redemption of its limited partnership units from our operating partnership equal to 15.0% of the amount, if any, by which: (i) the appraised value of our assets on the termination date, less any indebtedness secured by such assets, plus total distributions paid through the termination date, exceeds (ii) the sum of the total amount of capital raised from stockholders (less amounts paid to repurchase shares of our common stock pursuant to our share repurchase plan) and the total amount of cash equal to an annual 7.0% cumulative, non-compounded return on the gross proceeds from the sale of shares of our common stock through the termination date. In addition, our advisor may elect to defer its right to receive a subordinated distribution upon termination until either a listing or other liquidity event, including a liquidation, sale of substantially all of our assets or merger in which our stockholders receive in exchange for their shares of our common stock, shares of a company that are traded on a national securities exchange. As of September 30, 2016 and 2015 , we had not recorded any charges to earnings related to the subordinated distribution upon termination. Stock Purchase Plans Effective January 1, 2015, our Chief Executive Officer and Chairman of the Board of Directors, Jeffrey T. Hanson, our President, Chief Operating Officer and Director, Danny Prosky, and our Executive Vice President, General Counsel, Mathieu B. Streiff, each executed stock purchase plans, or the 2015 Stock Purchase Plans, whereby they each irrevocably agreed to invest 100% of their net after-tax base salary and cash bonus compensation earned as employees of American Healthcare Investors directly into our company by purchasing shares of our common stock. In addition, our former Chief Financial Officer, Shannon K S Johnson, our Executive Vice President — Acquisitions, Stefan K.L.

Purchases of shares of our common stock pursuant to the 2015 Stock Purchase Plans commenced with the officers’ regularly scheduled payroll payment paid on or after January 1, 2015. The shares of common stock were purchased at a price of $9.00 per share, reflecting the purchase price of the shares in our initial offering, exclusive of selling commissions and the dealer manager fee. The 2015 Stock Purchase Plans each terminated in connection with the termination of the primary portion of our initial offering.

Fair Value Measurements	15. Fair Value Measurements Assets and Liabilities Reported at Fair Value The table below presents our assets and liabilities measured at fair value on a recurring basis as of September 30, 2016 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Derivative financial instrument $ — $ 25,000 $ — $ 25,000 Contingent consideration receivables — — — — Total assets at fair value $ — $ 25,000 $ — $ 25,000 Liabilities: Derivative financial instrument $ — $ 64,000 $ — $ 64,000 Contingent consideration obligations — — 16,559,000 16,559,000 Warrants — — 960,000 960,000 Total liabilities at fair value $ — $ 64,000 $ 17,519,000 $ 17,583,000 The table below presents our assets and liabilities measured at fair value on a recurring basis as of December 31, 2015 , aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total Assets: Contingent consideration receivables $ — $ — $ — $ — Total assets at fair value $ — $ — $ — $ — Liabilities: Contingent consideration obligations $ — $ — $ 5,912,000 $ 5,912,000 Warrants — — 1,014,000 1,014,000 Total liabilities at fair value $ — $ — $ 6,926,000 $ 6,926,000 There were no transfers into or out of fair value measurement levels during the nine months ended September 30, 2016 and 2015 . Derivative Financial Instruments We use interest rate swaps and interest rate caps to manage interest rate risk associated with floating-rate debt. The valuation of these instruments is determined using widely accepted valuation techniques including a discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, as well as option volatility. The fair values of interest rate swaps are determined by netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates derived from observable market interest rate curves. To comply with the provisions of ASC Topic 820, Fair Value Measurements and Disclosures , or ASC Topic 820, we incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Although we have determined that the majority of the inputs used to value our derivative financial instruments fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with these instruments utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by us and our counterparty. However, as of September 30, 2016 , we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Contingent Consideration Assets As of September 30, 2016 , we have not recorded any contingent consideration receivables. In connection with our purchase of King of Prussia PA MOB in January 2015, there was a contingent consideration receivable in the amount of either $0 or $1,100,000 . We would have received $1,100,000 in the event that within one year of the acquisition date certain criteria were not met, including the seller leasing 4,536 square feet of GLA meeting certain lease terms, occupancy by the tenant, delivery of a signed estoppel by the tenant and our receipt of the first month’s rent under the lease. Such contingency expired in January 2016. In addition, in connection with our acquisition of Mt. Juliet TN MOB in March 2015, there is a contingent consideration receivable in the range of $0 up to a maximum of $355,000 . We would receive payment of contingent consideration in the event that a tenant occupying 6,611 square feet of GLA terminates their lease prior to March 31, 2018, and to the extent there is a shortfall in rent from any replacement tenant. As of September 30, 2016 , we do not believe that we will receive such amounts and therefore we have not recorded any contingent consideration receivables. When recorded by us, contingent consideration receivables will be included in other assets, net in our accompanying condensed consolidated balance sheets. Liabilities As of September 30, 2016 and December 31, 2015 , we have accrued $16,559,000 and $5,912,000 , respectively, as contingent consideration obligations in connection with our property acquisitions, which is included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets. Such consideration will be paid upon various conditions being met, including our tenants achieving certain operating performance metrics and sellers’ leasing unoccupied space, as discussed below. Of the amount accrued as of September 30, 2016 , $16,011,000 relates to our acquisition of North Carolina ALF Portfolio in January and June 2015, $498,000 relates to our acquisition of Stockbridge GA MOB II and $50,000 relates to our acquisition of King of Prussia PA MOB. Of the amount accrued as of December 31, 2015 , $4,131,000 relates to our acquisition of North Carolina ALF Portfolio in January and June 2015, $1,381,000 relates to our acquisition of Stockbridge GA MOB II and $400,000 relates to our acquisition of King of Prussia PA MOB. The estimated total amount of $16,011,000 related to North Carolina ALF Portfolio will be paid based upon the computation in the lease agreement and receipt of notification within three years after the applicable acquisition date that the tenant has increased its earnings before interest, taxes, depreciation and rent cost, or EBITDAR, as defined in the lease agreement, for the preceding three months. There is no minimum required payment but the total maximum is capped at $35,144,000 and is also limited by the tenant’s ability to increase its EBITDAR. Any payment made will result in an increase in the monthly rent charged to the tenant and additional rental revenue to us. Upon the tenant meeting certain conditions under the lease agreement and providing us notice in October 2016, we paid $10,000,000 towards this obligation related to the Wake Forest Facility in November 2016. We have assumed that the tenant will meet the remaining conditions under the lease agreement and that we will pay the remaining contingent consideration for the three other facilities three years from the date of the applicable acquisition. As of September 30, 2016 , we have accrued $498,000 related to Stockbridge GA MOB II, and such consideration will be paid within 18 months of the acquisition date based on the seller’s leasing of one or both unoccupied spaces and achieving certain lease criteria. The payment of such consideration will occur after a qualified tenant delivers an estoppel, has taken occupancy and has begun paying rent under the new lease. The range of payment is $0 up to no limit and and we have assumed that the seller will lease both of the unoccupied spaces within the specified time frame. Warrants As of September 30, 2016 and December 31, 2015 , we have recorded $960,000 and $1,014,000 , respectively, related to warrants in Trilogy common units held by certain members of Trilogy’s pre-closing management, which is included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets. Once exercised, these warrants have redemption features similar to the common units held by members of Trilogy’s pre-closing management. See Note 12, Redeemable Noncontrolling Interests , for a further discussion. As of September 30, 2016 and December 31, 2015 , the carrying value is a reasonable estimate of fair value as the warrants were issued at fair value on December 1, 2015. Unobservable Inputs and Reconciliation The fair value of the contingent consideration is determined based on the facts and circumstances existing at each reporting date and the likelihood of the counterparty achieving the necessary conditions based on a probability weighted discounted cash flow analysis based, in part, on significant inputs which are not observable in the market. As a result, we have determined that our contingent consideration valuations are classified in Level 3 of the fair value hierarchy. Any changes in the fair value of our contingent consideration assets and obligations subsequent to their acquisition date valuations are charged to earnings. Gains and losses recognized on contingent consideration assets and obligations are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. The following table shows quantitative information about unobservable inputs related to Level 3 fair value measurements used as of September 30, 2016 and December 31, 2015 for the contingent consideration obligations: Range of Inputs or Inputs Fair Value Acquisition Unobservable Inputs(1) September 30, 2016 December 31, 2015 September 30, 2016 December 31, 2015 North Carolina ALF Portfolio — North Raleigh and Mooresville(2) Tenant’s Annualized EBITDAR, as defined, for the Three Months Prior to Payment $ 3,720,000 $ 3,516,000 $ 6,011,000 $ 3,524,000 Timing of Payment January 27, 2018 January 27, 2018 Applicable Rate, as defined in the lease agreement 7.2% 7.2% Discount Rate per Annum 0.77% 1.06% Percentage of Eligible Payment Requested 100% 100% King of Prussia PA MOB(3) Percentage of Allowance for Leasing Commissions to be Paid 100% 100% $ 50,000 $ 400,000 North Carolina ALF Portfolio — Clemmons and Wake Forest(2) Tenant’s Annualized EBITDAR, as defined, for the Three Months Prior to Payment $ 2,267,000 $ 1,491,000 $ 10,000,000 $ 607,000 Timing of Payment October 31, 2016 and June 28, 2018 June 28, 2018 Applicable Rate, as defined in the lease agreement 7.2% 7.2% Discount Rate per Annum 0.77% 1.06% Percentage of Eligible Payment Requested 100% 100% Stockbridge GA MOB II(4) Percentage of Total Unoccupied Square Footage Leased Up 100% 100% $ 498,000 $ 1,381,000 Timing of Payment March 3, 2017 March 3, 2017 Capitalization Rate 7.5% 7.5% Initial Base Rent per Square Foot $ 17.00 $ 17.00 Tenant Improvement Allowance per Square Foot $ 30.00 $ 30.00 Lease Commission Rate 4.00% 4.00% ___________ (1) Significant increases or decreases in any of the unobservable inputs in isolation or in the aggregate would result in a significantly higher or lower fair value measurement to the contingent consideration obligation as of September 30, 2016 and December 31, 2015 . (2) The most significant input to the valuation is the tenant’s annualized EBITDAR, as defined in the lease agreement. An increase (decrease) in the tenant’s annualized EBITDAR would increase (decrease) the fair value. (3) An increase (decrease) in the leasing commissions to be paid would increase (decrease) the fair value. (4) The most significant input to the valuation is the percentage of total unoccupied square footage leased up. An increase (decrease) in the percentage of total unoccupied square footage leased up would increase (decrease) the fair value. An increase (decrease) in the tenant improvement allowance per square foot would decrease (increase) the fair value. An increase (decrease) in initial base rent would increase (decrease) the fair value. The following is a reconciliation of the beginning and ending balances of our contingent consideration assets and obligations for the three and nine months ended September 30, 2016 and 2015 : Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Contingent Consideration Receivables: Beginning balance $ — $ — $ — $ — Additions to contingent consideration receivables — — — — Realized/unrealized (gains) losses recognized in earnings — — — — Ending balance $ — $ — $ — $ — Amount of total (gains) losses included in earnings attributable to the change in unrealized (gains) losses related to assets still held $ — $ — $ — $ — Contingent Consideration Obligations: Beginning balance $ 5,820,000 $ 5,280,000 $ 5,912,000 $ 1,393,000 Additions to contingent consideration obligations — — — 4,467,000 Realized/unrealized losses (gains) recognized in earnings 10,739,000 29,000 10,997,000 (551,000 ) Settlements of obligations — — (350,000 ) — Ending balance $ 16,559,000 $ 5,309,000 $ 16,559,000 $ 5,309,000 Amount of total losses (gains) included in earnings attributable to the change in unrealized (gains) losses related to obligations still held $ 10,739,000 $ 29,000 $ 10,997,000 $ 83,000 Financial Instruments Disclosed at Fair Value ASC Topic 825, Financial Instruments, requires disclosure of the fair value of financial instruments, whether or not recognized on the face of the balance sheet. Fair value is defined under ASC Topic 820. Our accompanying condensed consolidated balance sheets include the following financial instruments: real estate notes receivable, debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits, accounts payable and accrued liabilities, accounts payable due to affiliates, mortgage loans payable and borrowings under our lines of credit and term loan. We consider the carrying values of cash and cash equivalents, accounts and other receivables, restricted cash, real estate deposits and accounts payable and accrued liabilities to approximate the fair value for these financial instruments based upon an evaluation of the underlying characteristics, market data and because of the short period of time between origination of the instruments and their expected realization. The fair value of cash and cash equivalents is classified in Level 1 of the fair value hierarchy. The fair value of accounts payable due to affiliates is not determinable due to the related party nature of the accounts payable. The fair value of the other financial instruments is classified in Level 2 of the fair value hierarchy. The fair value of our real estate notes receivable and debt security investment are estimated using a discounted cash flow analysis using interest rates available to us for investments with similar terms and maturities. The fair value of the mortgage loans payable and our lines of credit and term loan are estimated using a discounted cash flow analysis using borrowing rates available to us for debt instruments with similar terms and maturities. We have determined that the valuations of our real estate notes receivable, debt security investment, mortgage loans payable and lines of credit and term loan are classified in Level 2 within the fair value hierarchy. The carrying amounts and estimated fair values of such financial instruments were as follows: September 30, 2016 December 31, 2015 Carrying Amount Fair Value Carrying Amount Fair Value Financial Assets: Real estate notes receivable $ 80,257,000 $ 82,216,000 $ 81,716,000 $ 80,845,000 Debt security investment $ 64,352,000 $ 93,373,000 $ 62,761,000 $ 94,393,000 Financial Liabilities: Mortgage loans payable $ 482,966,000 $ 494,362,000 $ 295,270,000 $ 294,701,000 Lines of credit and term loan $ 598,996,000 $ 609,418,000 $ 343,656,000 $ 350,000,000

Income Tax Disclosure [Abstract]
Income Taxes	16. Income Taxes As a REIT, we generally will not be subject to federal income tax on taxable income that we distribute to our stockholders. We have elected to treat certain of our consolidated subsidiaries as taxable REIT subsidiaries, or TRSs, pursuant to the Code. TRSs may participate in services that would otherwise be considered impermissible for REITs and are subject to federal and state income tax at regular corporate tax rates. The components of loss before taxes for the three and nine months ended September 30, 2016 and 2015 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Domestic $ (56,233,000 ) $ (15,942,000 ) $ (154,887,000 ) $ (36,883,000 ) Foreign (135,000 ) (1,669,000 ) (277,000 ) (1,669,000 ) Loss before income taxes $ (56,368,000 ) $ (17,611,000 ) $ (155,164,000 ) $ (38,552,000 ) The components of income tax (benefit) expense for the three and nine months ended September 30, 2016 and 2015 were as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Federal deferred $ 2,859,000 $ (2,547,000 ) $ (5,535,000 ) $ (3,115,000 ) State deferred (68,000 ) (383,000 ) (924,000 ) (462,000 ) Foreign deferred 87,000 — — — Federal current 107,000 326,000 115,000 326,000 Foreign current (45,000 ) 4,000 122,000 4,000 Valuation allowances (2,942,000 ) 2,930,000 6,395,000 3,577,000 Total income tax (benefit) expense $ (2,000 ) $ 330,000 $ 173,000 $ 330,000 Current Income Tax Federal and state income taxes are generally a function of the level of income recognized by our TRSs. Foreign income taxes are generally a function of our income on our real estate and real estate-related investments located in the UK and Isle of Man. Deferred Taxes Deferred income tax is generally a function of the period’s temporary differences (primarily basis differences between tax and financial reporting for real estate assets and equity investments) and generation of tax net operating losses that may be realized in future periods depending on sufficient taxable income. We apply the rules under ASC 740-10, Accounting for Uncertainty in Income Taxes, for uncertain tax positions using a “more likely than not” recognition threshold for tax positions. Pursuant to these rules, we will initially recognize the financial statement effects of a tax position when it is more likely than not, based on the technical merits of the tax position, that such a position will be sustained upon examination by the relevant tax authorities. If the tax benefit meets the “more likely than not” threshold, the measurement of the tax benefit will be based on our estimate of the ultimate tax benefit to be sustained if audited by the taxing authority. As of September 30, 2016 and December 31, 2015 , we did not have any tax benefits or liabilities for uncertain tax positions that we believe should be recognized in our accompanying condensed consolidated financial statements. We used estimated fair value for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed for the Trilogy acquisition in December 2015. During this quarter, we obtained additional information that required revisions to the preliminary purchase price allocation. Specifically, the basis differences between tax and book were updated, and as a result, a deferred tax liability was recorded. The primary driver of this difference was the use of bonus depreciation for tax purposes. See Note 17, Business Combinations , for a further discussion. The additional information obtained also impacted our allocation of deferred tax assets. An election was filed to step up the tax basis of certain assets pursuant to section 743 of the Code, and additional book/tax basis differences were finalized related to the contribution of certain assets by Trilogy to its TRS subsidiary prior to our acquisition of Trilogy. The contribution was structured as a tax free contribution, pursuant to section 351 of the Code. Straight line rent basis differences and net operating losses contributed to the growth in the deferred tax asset account in 2016. We assess the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. A valuation allowance is established if we believe it is more likely than not that all or a portion of the deferred tax assets are not realizable. As of September 30, 2016 , our valuation allowance substantially reserves the net deferred tax asset due to inherent uncertainty of future income. We will continue to monitor industry and economic conditions, and our ability to generate taxable income based on our business plan and available tax planning strategies, which would allow us to utilize the tax benefits of the net deferred tax assets and thereby allow us to reverse all, or a portion of, our valuation allowance in the future.

Business Combinations [Abstract]
Business Combinations	17. Business Combinations Trilogy Preliminary Purchase Price Allocation We utilized estimated fair values for the preliminary allocation of consideration to the net tangible and intangible assets acquired and liabilities assumed for the acquisition of Trilogy in December 2015. As we continue to integrate Trilogy, we may obtain additional information on the acquired assets and assumed liabilities which, if significant, could require revisions to the preliminary purchase price allocation for Trilogy. Amounts for certain income tax accounts are also subject to change pending the filing of Trilogy’s pre-acquisition tax returns and the receipt of information from taxing authorities, which, if significant, could require revisions to preliminary assumptions and estimates. If we determine that any measurement period adjustments are significant, we will recognize those adjustments, including any related impacts to deferred tax positions, goodwill or net income, in the reporting period in which the adjustments are determined. The preliminary purchase price allocation to assets acquired and liabilities assumed for the acquisition of Trilogy in December 2015 was: Trilogy(1) Building and improvements $ 501,353,000 Land 42,157,000 Furniture, fixtures and equipment 59,192,000 Construction in progress 17,132,000 In-place leases 183,704,000 Purchase option assets 71,000,000 Capital lease assets 43,601,000 Trade names 30,267,000 Certificate of need 51,295,000 Other assets 42,293,000 Goodwill 70,610,000 Total assets acquired 1,112,604,000 Lines of credit (270,000,000 ) Mortgage loans payable, net (193,220,000 ) Capital lease obligations (47,660,000 ) Other liabilities (7,634,000 ) Deferred income tax liabilities (7,699,000 ) Total liabilities assumed (526,213,000 ) Net assets acquired $ 586,391,000 ___________ (1) Trilogy's assets acquired and liabilities assumed are consolidated and reported at 100% . At the time of acquisition, we owned approximately 67.6% of the net assets acquired. During the third quarter of 2016, we updated the purchase price allocation of Trilogy to adjust deferred income tax liabilities as of the Trilogy acquisition date for pre-merger Trilogy’s federal income tax returns and revised estimates. This measurement period adjustment was reflected in the table above as an increase to goodwill of $7,699,000 , with corresponding adjustments to deferred income tax liabilities, which is included in security deposits, prepaid rent and other liabilities, in our accompanying condensed consolidated balance sheets. There is no impact to our condensed consolidated statement of operations and comprehensive loss for the fiscal year ended December 31, 2015 and previously reported interim periods ended June 30, 2016 relating to this purchase price allocation adjustment. 2016 Business Combinations For the nine months ended September 30, 2016 , using cash on hand and debt financing, we completed 11 property acquisitions comprising 17 buildings, which have been accounted for as business combinations. The aggregate contract purchase price for these property acquisitions was $437,025,000 , plus closing costs, and acquisition fees of $11,775,000 , which are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. See Note 3, Real Estate Investments, Net , for a listing of the properties acquired, acquisition dates and the amount of financing initially incurred in connection with such acquisitions. Results of operations for the property acquisitions during the nine months ended September 30, 2016 are reflected in our accompanying condensed consolidated statements of operations and comprehensive loss for the period from the date of acquisition of each property through September 30, 2016 . For the period from the acquisition date through September 30, 2016 , we recognized the following amounts of revenue and net income for the property acquisitions: Acquisition Revenue Net Income 2016 Acquisitions $ 12,735,000 $ 670,000 The fair values of the assets acquired and liabilities assumed since October 1, 2015 were preliminary estimates determined using the income, cost and market approaches. Any necessary adjustments will be finalized within one year from the date of acquisition. The following table summarizes the acquisition date fair values of the assets acquired and liabilities assumed of our 11 property acquisitions in 2016: 2016 Acquisitions Building and improvements $ 396,665,000 Land 36,345,000 Furniture, fixtures and equipment 644,000 In-place leases 40,059,000 Above-market leases 1,324,000 Certificate of need 18,410,000 Purchase option assets (56,792,000 ) Total assets acquired 436,655,000 Below-market leases (1,423,000 ) Total liabilities assumed (1,423,000 ) Net assets acquired $ 435,232,000 Assuming the property acquisitions in 2016 discussed above had occurred on January 1, 2015, for the three and nine months ended September 30, 2016 and 2015 , unaudited pro forma revenue, net loss, net loss attributable to controlling interest and net loss per common share attributable to controlling interest — basic and diluted would have been as follows: Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 Revenue $ 248,949,000 $ 36,212,000 $ 746,682,000 $ 80,541,000 Net loss $ (51,121,000 ) $ (24,126,000 ) $ (133,978,000 ) $ (69,626,000 ) Net loss attributable to controlling interest $ (37,277,000 ) $ (21,931,000 ) $ (94,311,000 ) $ (60,327,000 ) Net loss pe r com mon share attributable to controlling interest — basic and diluted $ (0.19 ) $ (0.12 ) $ (0.49 ) $ (0.33 ) The unaudited pro forma adjustments assume that the offering proceeds, at a price of $10.00 per share, net of offering costs, were raised as of January 1, 2015. In addition, acquisition related expenses associated with the acquisitions have been excluded from the pro forma results in 2016 and added to the 2015 pro forma results. The pro forma results are not necessarily indicative of the operating results that would have been obtained had the acquisitions occurred at the beginning of the periods presented, nor are they necessarily indicative of future operating results. 2015 Business Combinations For the nine months ended September 30, 2015 , using net proceeds from our initial offering and the assumption of mortgage loans payable, we completed 19 property acquisitions comprising 45 buildings, which have been accounted for as business combinations. The aggregate contract purchase price for these property acquisitions was $763,367,000 , plus closing costs, and acquisition fees of $25,338,000 , which are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive loss. Results of operations for the property acquisitions during the nine months ended September 30, 2015 are reflected in our accompanying condensed consolidated statements of operations and comprehensive loss for the period from the date of acquisition of each property through September 30, 2015 . We present separately Independence MOB Portfolio and Pennsylvania Senior Housing Portfolio, which are individually significant property acquisitions during the nine months ended September 30, 2015 , and aggregate the rest of the property acquisitions during the nine months ended September 30, 2015 . The fair values of the assets acquired and liabilities assumed were preliminarily determined using the income, cost and market approaches. The fair value measurements were primarily based on significant inputs that are not observable in the market and are considered Level 3 under the Fair Value Measurement and Disclosure framework. For the period from the acquisition date through September 30, 2015 , we recognized the following amounts of revenue and net income (loss) for the property acquisitions: Acquisition Revenue Net Income (Loss) Independence MOB Portfolio $ 10,516,000 $ 2,039,000 Pennsylvania Senior Housing Portfolio $ 4,261,000 $ (1,454,000 ) Other 2015 Acquisitions $ 25,874,000 $ (401,000 ) The following table summarizes the acquisition date fair values of the assets acquired and liabilities assumed of our 19 property acquisitions, which we determined using Level 2 and Level 3 inputs: Independence MOB Portfolio Pennsylvania Senior Housing Portfolio Other 2015 Acquisitions Building and improvements $ 113,727,000 $ 76,970,000 $ 445,801,000 Land 7,367,000 2,994,000 44,089,000 Furniture, fixtures and equipment — 635,000 1,654,000 In-place leases 7,182,000 8,057,000 40,418,000 Above-market leases 1,321,000 — 1,099,000 Leasehold interest 5,715,000 — 95,000 Total assets acquired 135,312,000 88,656,000 533,156,000 Mortgage loans payable, net — (13,254,000 ) (71,940,000 ) Below-market leases (350,000 ) — (27,000 ) Other liabilities — — (4,467,000 ) (1 ) Total liabilities assumed (350,000 ) (13,254,000 ) (76,434,000 ) Net assets acquired $ 134,962,000 $ 75,402,000 $ 456,722,000 ___________ (1) Included in other liabilities are $4,067,000 and $400,000 accrued for as contingent consideration obligations in connection with the purchase of North Carolina ALF Portfolio and King of Prussia PA MOB, respectively. For a further discussion, see Note 15, Fair Value Measurements — Assets and Liabilities Reported at Fair Value — Contingent Consideration. Assuming the property acquisitions in 2015 discussed above had occurred on January 1, 2014, for the three and nine months ended September 30, 2015 and 2014 , unaudited pro forma revenue, net loss, net (loss) income attributable to controlling interest and net (loss) income per common share attributable to controlling interest — basic and diluted would have been as follows: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Revenue $ 32,065,000 $ 27,149,000 $ 99,096,000 $ 76,261,000 Net loss $ (5,749,000 ) $ (4,812,000 ) $ (997,000 ) $ (37,867,000 ) Net (loss) income attributable to controlling interest $ (3,245,000 ) $ (4,813,000 ) $ 1,507,000 $ (37,867,000 ) Net (loss) income per com mon share attributable to controlling interest — basic and diluted $ (0.01 ) $ (0.06 ) $ 0.01 $ (0.48 ) The unaudited pro forma adjustments assume that the offering proceeds, at a price of $10.00 per share, net of offering costs, were raised as of January 1, 2014. In addition, acquisition related expenses associated with the acquisitions have been excluded from the pro forma results in 2015 and added to the 2014 pro forma results. The pro forma results are not necessarily indicative of the operating results that would have been obtained had the acquisitions occurred at the beginning of the periods presented, nor are they necessarily indicative of future operating results.

Segment Reporting [Abstract]
Segment Reporting Disclosure	18. Segment Reporting ASC Topic 280, Segment Reporting , establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. As of September 30, 2016 , we evaluated our business and made resource allocations based on six reportable business segments: medical office buildings, hospitals, skilled nursing facilities, senior housing, senior housing — RIDEA and integrated senior health campuses. We segregate our operations into reporting segments in order to assess the performance of our business in the same way that management reviews our performance and makes operating decisions. Accordingly, when we acquired our first medical office building in June 2014; senior housing facility in September 2014; hospital in December 2014; senior housing — RIDEA portfolio in May 2015; skilled nursing facilities in October 2015; and integrated senior health campuses in December 2015, we added a new reportable business segment at such time. Our medical office buildings are typically leased to multiple tenants under separate leases in each building, thus requiring active management and responsibility for many of the associated operating expenses (although many of these are, or can effectively be, passed through to the tenants). In addition, our medical office buildings segment includes the Mezzanine Notes. Our hospital investments are primarily single-tenant properties that lease the facilities to unaffiliated tenants under triple-net and generally master leases that transfer the obligation for all facility operating costs (including maintenance, repairs, taxes, insurance and capital expenditures) to the tenant. Our skilled nursing facilities and senior housing facilities are similarly structured as our hospital investments. In addition, our senior housing segment includes Crown Senior Care Facility and our debt security investment. Our senior housing — RIDEA properties include senior housing facilities that are owned and operated utilizing a RIDEA structure. Our integrated senior health campuses include a range of assisted living, memory care, independent living, skilled nursing services and certain ancillary businesses. We evaluate performance based upon segment net operating income. We define segment net operating income as total revenues, less property operating expenses and rental expenses, which excludes depreciation and amortization, general and administrative expenses, acquisition related expenses, interest expense, foreign currency gain (loss), interest and other income, loss from unconsolidated entities and income tax benefit (expense) for each segment. We believe that net income (loss), as defined by GAAP, is the most appropriate earnings measurement. However, we believe that segment net operating income serves as a useful supplement to net income (loss) because it allows investors and our management to measure unlevered property-level operating results and to compare our operating results to the operating results of other real estate companies and between periods on a consistent basis. Interest expense, depreciation and amortization and other expenses not attributable to individual properties are not allocated to individual segments for purposes of assessing segment performance. Non-segment assets primarily consist of corporate assets including cash and cash equivalents, real estate deposits, deferred financing costs, other receivables and other assets not attributable to individual properties. Summary information for the reportable segments during the three and nine months ended September 30, 2016 and 2015 was as follows: Medical Office Buildings Skilled Nursing Facilities Hospitals Senior

Concentration of Credit Risk

Concentration of Credit Risk [Abstract]
Concentration of Credit Risk	19. Concentration of Credit Risk Financial instruments that potentially subject us to a concentration of credit risk are primarily real estate notes receivable and debt security investment, cash and cash equivalents, accounts and other receivables, restricted cash and real estate deposits. We are exposed to credit risk with respect to the real estate notes receivable and debt security investment, but we believe collection of the outstanding amount is probable. We believe that the risk is further mitigated as the real estate notes receivable are secured by property and there is a guarantee of completion agreement executed between the parent company of the borrowers and us. Cash and cash equivalents are generally invested in investment-grade, short-term instruments with a maturity of three months or less when purchased. We have cash and cash equivalents in financial institutions that are insured by the Federal Deposit Insurance Corporation, or FDIC. As of September 30, 2016 and December 31, 2015 , we had cash and cash equivalents in excess of FDIC insured limits. We believe this risk is not significant. Concentration of credit risk with respect to accounts receivable from tenants is limited. We perform credit evaluations of prospective tenants and security deposits are obtained at the time of property acquisition and upon lease execution. Based on leases in effect as of September 30, 2016 , one state in the United States accounted for 10.0% or more of the annualized base rent of our total property portfolio. Properties located in Indiana accounted for 37.8% of the annualized base rent of our total property portfolio. Accordingly, there is a geographic concentration of risk subject to fluctuations in such state’s economy. Based on leases in effect as of September 30, 2016 , our six reportable business segments, integrated senior health campuses, medical office buildings, senior housing — RIDEA, senior housing, skilled nursing facilities and hospitals, accounted for 47.3% , 31.3% , 11.2% , 5.1% , 5.1% and 0.0% , respectively, of our annualized base rent. As of September 30, 2016 , none of our tenants at our properties accounted for 10.0% or more of our aggregate annualized base rent, which is based on contractual base rent from leases in effect inclusive of our senior housing — RIDEA facilities and integrated senior health campuses operations as of September 30, 2016 .

Earnings Per Share [Abstract]
Per Share Data	20. Per Share Data We report earnings (loss) per share pursuant to ASC Topic 260, Earnings per Share . Basic earnings (loss) per share for all periods presented are computed by dividing net income (loss) applicable to common stock by the weighted average number of shares of our common stock outstanding during the period. Net income (loss) applicable to common stock is calculated as net income (loss) attributable to controlling interest less distributions allocated to participating securities of $6,000 and $2,000 , respectively, for the three months ended September 30, 2016 and 2015 , and $12,000 and $6,000 , respectively, for the nine months ended September 30, 2016 and 2015 . Diluted earnings (loss) per share are computed based on the weighted average number of shares of our common stock and all potentially dilutive securities, if any. Nonvested shares of our restricted common stock and redeemable limited partnership units of our operating partnership are participating securities and give rise to potentially dilutive shares of our common stock. As of September 30, 2016 and 2015 , there were 40,000 and 22,000 nonvested shares, respectively, of our restricted common stock outstanding, but such shares were excluded from the computation of diluted earnings per share because such shares were anti-dilutive during these periods. As of September 30, 2016 and 2015 , there were 222 units of redeemable limited partnership units of our operating partnership outstanding, but such units were also excluded from the computation of diluted earnings per share because such units were anti-dilutive during these periods.

Subsequent Events [Abstract]
Subsequent Events	21. Subsequent Events Property Acquisition Subsequent to September 30, 2016 , we completed the acquisition of one building from an unaffiliated party, which we added to our existing Fox Grape SNF Portfolio. The aggregate contract purchase price of this acquisition was $22,500,000 and we paid $506,000 in acquisition fees to our advisor in connection with this acquisition. We have not yet measured the fair value of the tangible and identified intangible assets and liabilities nor the proforma results of the acquisition. The following is a summary of our acquisition subsequent to September 30, 2016 : Acquisition(1) Location Type Date Contract Purchase Price Mortgage Loan Payable(2) 2016 Corporate Line of Credit(3) Acquisition Fee(4) Fox Grape SNF Portfolio(5) Quincy, MA Skilled Nursing 11/01/16 $ 22,500,000 $ 16,133,000 $ 6,000,000 $ 506,000 ___________ (1) We own 100% of the property acquired subsequent to September 30, 2016 . (2) Represents the principal balance of the mortgage loan payable placed on the property at the time of acquisition. (3) Represents borrowings under the 2016 Corporate Line of Credit at the time of acquisition. (4) Our advisor was paid in cash, as compensation for services rendered in connection with the investigation, selection and acquisition of our properties, an acquisition fee of 2.25% of the contract purchase price of the property. (5) On November 1, 2016, we added one additional facility to our existing Fox Grape SNF Portfolio. The other five facilities were acquired in July 2016. Amended and Restated Distribution Reinvestment Plan Price Effective October 5, 2016, the Amended and Restated DRIP amended the price at which shares of our common stock will be issued pursuant to the Secondary DRIP Offering. Pursuant to the Amended and Restated DRIP, shares are issued at a price equal to the most recently estimated value of one share of our common stock, as approved and established by our board. The Amended and Restated DRIP became effective with the distribution payment to stockholders paid in the month of November 2016, which distributions were reinvested at $9.01 per share, the estimated per share net asset value, or NAV, unanimously approved and established by our board on October 5, 2016. Formerly, shares were issued pursuant to the Secondary DRIP Offering at 95.0% of the estimated value of one share of our common stock, as estimated by our board. In all other material respects, the terms of the Secondary DRIP Offering remain unchanged by the Amended and Restated DRIP. Amended and Restated Share Repurchase Plan Effective October 5, 2016, we amended and restated our share repurchase plan. The Amended and Restated Share Repurchase Plan, which will take effect with respect to share repurchase requests submitted during the fourth quarter 2016, amends the price at which shares of our common stock will be repurchased pursuant to the share repurchase plan by amending the definition of the term Repurchase Amount, as such term is used in the share repurchase plan. Upon effectiveness of the Amended and Restated Share Repurchase Plan, the Repurchase Amount that will be used to calculate the price at which shares will be repurchased will be the lesser of (i) the amount per share that a stockholder paid for their shares of our common stock or (ii) the most recent estimated value of one share of our common stock, as determined by our board, which was $9.01 per share as unanimously approved and established by our board on October 5, 2016. Formerly, as a result of the termination of the Company’s initial public offering of shares in April 2015, the Repurchase Amount was an amount determined by our board, in its discretion. In addition, the Amended and Restated Share Repurchase Plan amends the price at which shares will be repurchased as a result of a stockholder’s death or “qualifying disability”, as defined in our share repurchase plan. Upon effectiveness of the Amended and Restated Share Repurchase Plan, shares repurchased in connection with a stockholder’s death or qualifying disability will be repurchased at a price per share equal to 100% of the Repurchase Amount. Formerly, shares repurchased in connection with a stockholder’s death or qualifying disability were repurchased at 100% of the price paid by the stockholder to acquire the shares of the Company’s common stock. In all other material respects, the terms of the share repurchase plan remain unchanged by the Amended and Restated Share Repurchase Plan.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Because we are the sole general partner of our operating partnership and have unilateral control over its management and major operating decisions (even if additional limited partners are admitted to our operating partnership), the accounts of our operating partnership are consolidated in our accompanying condensed consolidated financial statements. All intercompany accounts and transactions are eliminated in consolidation. Basis of Presentation Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries in which we have control, as well as any variable interest entities, or VIEs, in which we are the primary beneficiary. We evaluate our ability to control an entity, and whether the entity is a VIE and of which we are the primary beneficiary, by considering substantive terms of the arrangement and identifying which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance as defined in Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation , or ASC Topic 810. We operate and intend to co ntinue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries of which we have control, will own substantially all of the interests in properties acquired on our behalf.
Interim Unaudited Financial Data	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 view, of a normal recurring nature and necessary for a fair presentation of our financial position, results of operations and cash flows for the interim period. Interim results of operations are not necessarily indicative of the results to be expected for the full year; such full year results may be less favorable. In preparing our accompanying condensed consolidated financial statements, management has evaluated subsequent events through the financial statement issuance date. We believe that although the disclosures contained herein are adequate to prevent the information presented from being misleading, our accompanying condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto included in our 2015 Annual Report on Form 10-K, as filed with the SEC on March 30, 2016.
Use of Estimates	Use of Estimates The preparation of our accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, as well as the disclosure of contingent assets and liabilities, at the date of our condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates are made and evaluated on an on-going basis using information that is currently available as well as various other assumptions believed to be reasonable under the circumstances. Actual results could differ from those estimates, perhaps in material adverse ways, and those estimates could be different under different assumptions or conditions.
Allowance for Uncollectible Accounts	Allowance for Uncollectible Accounts Tenant and resident receivables and unbilled deferred rent receivables are carried net of an allowance for uncollectible amounts. An allowance is maintained for estimated losses resulting from the inability of certain tenants or residents to meet the contractual obligations under their lease agreements. We also maintain an allowance for deferred rent receivables arising from the straight-line recognition of rents. Such allowances are charged to bad debt expense, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive loss. Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant’s or resident’s financial condition, security deposits, letters of credit, lease guarantees, current economic conditions and other relevant factors.
Accounts Payable and Accrued Liabilities	Accounts Payable and Accrued Liabilities As of September 30, 2016 and December 31, 2015 , accounts payable and accrued liabilities consisted primarily of reimbursement of payroll related costs to the managers of our senior housing — RIDEA facilities and integrated senior health campuses
Derivative Financial Instruments	Derivative Financial Instruments We are exposed to the effect of interest rate changes in the normal course of business. We seek to mitigate these risks by following established risk management policies and procedures, which include the occasional use of derivatives. Our primary strategy in entering into derivative contracts, such as fixed interest rate swaps and interest rate caps, is to add stability to interest expense and to manage our exposure to interest rate movements by effectively converting a portion of our variable-rate debt to fixed-rate debt. We do not enter into derivative instruments for speculative purposes. Derivatives are recognized as either assets or liabilities in our accompanying condensed consolidated balance sheets and are measured at fair value in accordance with ASC Topic 815, Derivatives and Hedging , or ASC Topic 815. ASC Topic 815 establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts and for hedging activities. Since our derivative instruments are not designated as hedge instruments, they do not qualify for hedge accounting under ASC Topic 815. Changes in the fair value of interest rate derivative financial instruments are recorded as a component of interest expense in gain (loss) in fair value of derivative financial instruments in our accompanying condensed consolidated statements of operations and comprehensive loss.
Reclassifications	deferred financing costs, net, related to our mortgage loans payable have been reclassified from other assets, net to mortgage loans payable, net in our accompanying condensed consolidated balance sheets to conform to the current period presentation in accordance with Accounting Standards Update, or ASU, 2015-03, Simplifying the Presentation of Debt Issuance Costs, or ASU 2015-03. Such reclassification did not have a material impact on our consolidated financial statements. Reclassifications
Recently Issued Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, or ASU 2014-09, which replaces the existing accounting standards for revenue recognition. ASU 2014-09 provides a five-step framework to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration expected to be received in exchange for those goods or services. Since its issuance, the FASB has amended several aspects of ASU 2014-09, including provisions that address principal-versus-agent implementation guidance and identifying performance obligations. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017. It may be adopted either by restating all years presented in the financial statements or by recording the impact of adoption as an adjustment to retained earnings at the beginning of the year of adoption. We have not yet selected a transition method nor have we determined the impact the adoption of ASU 2014-09 and its amendments on January 1, 2018 will have on our consolidated financial statements. In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, or ASU 2015-02, which amends the consolidation analysis required under ASC Topic 810. Specifically, ASU 2015-02: (i) modifies the evaluation of whether limited partnerships and similar legal entities are VIEs; (ii) eliminates the presumption that a general partner should consolidate a limited partnership; and (iii) amends the effect of fee arrangements in the primary beneficiary determination. Further, the application of ASU 2015-02 permits the use of either the full retrospective or modified retrospective adoption approach. ASU 2015-02 is effective for interim and annual reporting periods beginning after December 15, 2015 with early adoption permitted. We adopted ASU 2015-02 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs , or ASU 2015-03, which amends the presentation of debt issuance costs in the financial statements to present such costs as a direct deduction from the carrying amount of the related debt liability rather than as an asset. Amortization of such costs is required to be reported as interest expense. In August 2015, the FASB issued ASU 2015-15, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements , or ASU 2015-15, which clarified that debt issuance costs associated with line of credit arrangements may continue to be presented as an asset, regardless of whether there are any outstanding borrowings on the line of credit arrangement. The application of ASU 2015-03 requires retrospective adjustment of all prior periods presented. ASU 2015-03 is effective for interim and annual reporting periods beginning after December 15, 2015 with early adoption permitted. We adopted ASU 2015-03 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, or ASU 2015-16, which eliminates the requirement to restate prior period financial statements for measurement period adjustments in a business combination. The cumulative effect of a measurement period adjustment as a result of a change in the provisional amounts, calculated as if the accounting had been completed as of the acquisition date, is required to be recorded in the reporting period in which the adjustment amount is determined, rather than retrospectively. Further, ASU 2015-16 requires that the acquirer present separately on the face of the income statement, or disclose in the notes, the portion of the amount recorded in the 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 interim and annual reporting periods beginning after December 15, 2015 and should be applied prospectively to adjustments to provisional amounts that occur after the effective date. Early adoption is permitted for financial statements that have not yet been made available for issuance. We adopted ASU 2015-16 on January 1, 2016, which did not have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities , or ASU 2016-01, which amends the classification and measurement of financial instruments. ASU 2016-01 revises the accounting related to: (i) the classification and measurement of investments in equity securities; and (ii) the presentation of certain fair value changes for financial liabilities measured at fair value. ASU 2016-01 also amends certain disclosure requirements associated with the fair value of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, with respect to only certain of the amendments in ASU 2016-01, for financial statements that have not yet been made available for issuance. ASU 2016-01 requires the application of the amendments by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, with certain exceptions. We have not yet determined the impact the adoption of ASU 2016-01 on January 1, 2018 will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , or ASU 2016-02, which amends the guidance on accounting for leases, including extensive amendments to the disclosure requirements. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under ASU 2016-02, lessor accounting is largely unchanged. ASU 2016-02 is effective for fiscal years and interim periods beginning after December 15, 2018. Early adoption is permitted for financial statements that have not yet been made available for issuance. ASU 2016-02 requires a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We have not yet determined the impact the adoption of ASU 2016-02 on January 1, 2019 will have on our consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, or ASU 2016-09, which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures and statutory withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 requires disclosures about a change in accounting principle under ASC 250, Accounting Changes and Error Corrections , in the period of adoption. ASU 2016-09 is effective for fiscal years and interim periods beginning after December 15, 2016. Early adoption is permitted for financial statements that have not yet been made available for issuance. We do not expect the adoption of ASU 2016-09 on January 1, 2017 to have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments, or ASU 2016-13, which introduces a new approach to estimate credit losses on certain types of financial instruments based on expected losses. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years and interim periods beginning after December 15, 2019. Early adoption is permitted after December 15, 2018. We have not yet determined the impact the adoption of ASU 2016-13 on January 1, 2020 will have on our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, or ASU 2016-15, which intends to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. ASU 2016-15 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We have not yet determined the impact the adoption of ASU 2016-15 on January 1, 2018 will have on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory, or ASU 2016-16, which removes the prohibition in ASC 740, Income Taxes , against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for fiscal years and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in an interim period. We have not yet determined the impact the adoption of ASU 2016-16 on January 1, 2018 will have on our consolidated financial statements. In October 2016, the FASB issued ASU 2016-17, Interests Held through Related Parties That Are under Common Control , or ASU 2016-17, which amends the consolidation requirements that apply to a single decision maker’s evaluation of interests held through related parties that are under common control when it is determining whether it is the primary beneficiary of a VIE. ASU 2016-17 is effective for annual periods beginning on or after December 15, 2016. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of ASU 2016-17 on December 15, 2016 to have a material impact on our consolidated financial statements.

(2) Our advisor was paid in cash, as compensation for services in connection with real estate-related investments, an acquisition fee of 2.00% of the total amount advanced or invested through September 30, 2016 . (3) On February 4, 2015, we acquired eight promissory notes at par in the aggregate outstanding principal amount of $60,217,000 , or the Mezzanine Notes, comprising four fixed-rate notes in the aggregate outstanding principal amount of $28,650,000 , or the Mezzanine Fixed Rate Notes, and four floating-rate notes in the aggregate outstanding principal amount of $31,567,000 , or the Mezzanine Floating Rate Notes. The Mezzanine Notes evidence interests in a portion of a mezzanine loan that consisted in total of 40 promissory notes in the aggregate outstanding principal amount of $389,852,000 . The mezzanine loan is secured by pledges of equity interests in the owners of a portfolio of domestic healthcare properties, which such owners are themselves owned indirectly by a non-wholly owned subsidiary of NorthStar Realty Finance Corp. The maturity date of the Mezzanine Floating Rate Notes may be extended by three successive one -year extension periods at the borrower’s option, subject to satisfaction of certain conditions. In October 2016, the borrower exercised its right to extend the maturity date of the Mezzanine Floating Rate Notes for one year to December 2017. (4) We entered into a facility agreement with Caring Homes (TFP) Group Limited, or the CHG Borrower, an unaffiliated third party, on September 16, 2015. The facility agreement, as amended, matures on November 15, 2016. The facility agreement, as amended, is collateralized by two senior housing facilities in the United Kingdom, or the UK, and the income from the CHG Borrower’s operations. Based on the currency exchange rate as of September 30, 2016 , the maximum amount of advances available was £16,000,000 , or approximately $20,750,000 , and the outstanding balance as of September 30, 2016 was £15,276,000 , or approximately $19,812,000 . Based on the currency exchange rate as of September 30, 2016 , approximately $938,000 remained available for future funding under Crown Senior Care Facility, subject to certain conditions set forth in the applicable loan agreement, as amended. As of September 30, 2016 , the CHG Borrower has been identified as a VIE. We do not consolidate such VIE because we do not have the ability to control the activities that most significantly impact the VIE’s economic performance. Our exposure to loss as a result of involvement with such VIE is limited to the outstanding balance of Crown Senior Care Facility. (5) Balance represents the original principal balance, increased by any subsequent advances and decreased by any subsequent principal paydowns, and only requires monthly interest payments. The Mezzanine Floating Rate Notes, Mezzanine Fixed Rate Notes and Crown Senior Care Facility are subject to certain prepayment restrictions if repaid before the respective maturity dates. (6) On October 15, 2015, we acquired a commercial mortgage-backed debt security, or the debt security, for a purchase price of $60,429,000 from an unaffiliated third party. The debt security was issued by FREMF 2015-KS03 Mortgage Trust, or the Mortgage Trust, and represents a 10.0% beneficial ownership interest in the Mortgage Trust. The Mortgage Trust owns a pool of 59 mortgage loans that are secured by 59 domestic senior housing facilities. The debt security bears an interest rate on the stated principal amount thereof equal to 4.24% per annum, the terms of which security provide for monthly interest-only payments. The debt security matures on August 25, 2025 at a stated amount of $93,433,000 , resulting in an anticipated yield-to-maturity of 10.0% per annum. The debt security is subordinate to all other interests in the Mortgage Trust and is not guaranteed by a government-sponsored entity. We classify our debt security investment as held-to-maturity and we have not recorded any unrealized holding gains or losses on such investment.
