	Organization and Description of Business
	Griffin-American Healthcare REIT II, Inc., a Maryland corporation, was incorporated as Grubb & Ellis Healthcare REIT II, Inc. on January 7, 2009 and therefore we consider that our date of inception. We were initially capitalized on February 4, 2009. Our board of directors adopted an amendment to our charter, which was filed with the Maryland State Department of Assessments and Taxation on January 3, 2012, to change our corporate name from Grubb & Ellis Healthcare REIT II, Inc. to Griffin-American Healthcare REIT II, Inc. We invest in a diversified portfolio of real estate properties, focusing primarily on medical office buildings and healthcare-related facilities. We may also originate and acquire secured loans and real estate-related investments. We generally seek investments that produce current income. We qualified to be taxed as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code, for federal income tax purposes beginning with our taxable year ended December 31, 2010 and we intend to continue to be taxed as a REIT.
	On August 24, 2009, we commenced a best efforts initial public offering, or our initial offering, of up to $3,285,000,000 of shares of our common stock. Until November 6, 2012, we offered to the public up to $3,000,000,000 of shares of our common stock for $10.00 per share in our primary offering and $285,000,000 of shares of our common stock pursuant to our distribution reinvestment plan, or the DRIP, for $9.50 per share. On November 7, 2012, we began selling shares of our common stock in our initial offering at $10.22 per share in our primary offering and issuing shares pursuant to the DRIP for $9.71 per share.
	On February 14, 2013, we terminated our initial offering. As of February 14, 2013, we had received and accepted subscriptions in our initial offering for 123,179,064 shares of our common stock, or $1,233,333,000, and a total of $40,167,000 in distributions were reinvested and 4,205,920 shares of our common stock were issued pursuant to the DRIP.
	On February 14, 2013, we commenced a best efforts follow-on public offering, or our follow-on offering, of up to $1,650,000,000 of shares of our common stock, in which we initially offered to the public up to $1,500,000,000 of shares of our common stock for $10.22 per share in our primary offering and $150,000,000 shares of our common stock for $9.71 per share pursuant to the DRIP. We reserved the right to reallocate the shares of common stock we offered in our follow-on offering between the primary offering and the DRIP. As such, during our follow-on offering, we reallocated an aggregate of $107,200,000 of shares from the DRIP to the primary offering. Accordingly, we offered to the public up to $1,607,200,000 of shares of our common stock in our primary offering and up to $42,800,000 of shares of our common stock pursuant to the DRIP. As of September 30, 2013, we had received and accepted subscriptions in our follow-on offering for 157,488,692 shares of our common stock, or $1,603,642,000, excluding shares of our common stock issued pursuant to the DRIP. On October 30, 2013, we terminated our follow-on offering. See Note 19, Subsequent Events — Status of our Follow-On Offering, for a further discussion.
	On September 9, 2013, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, to register a maximum of $100,000,000 of additional shares of our common stock pursuant to our distribution reinvestment plan, or the Secondary DRIP. The Registration Statement on Form S-3 was automatically effective with the Securities and Exchange Commission, or the SEC, upon its filing; however, we did not commence offering shares pursuant to the Secondary DRIP until October 30, 2013 following the termination of our follow-on offering.
	We conduct substantially all of our operations through Griffin-American Healthcare REIT II Holdings, LP, or our operating partnership. On January 3, 2012, our operating partnership filed an Amendment to the Certificate of Limited Partnership with the Delaware Department of State to change its name from Grubb & Ellis Healthcare REIT II Holdings, LP to Griffin-American Healthcare REIT II Holdings, LP. Until January 6, 2012, we were externally advised by Grubb & Ellis Healthcare REIT II Advisor, LLC, or our former advisor, pursuant to an advisory agreement, as amended and restated, or the G&E Advisory Agreement, between us and our former advisor. From August 24, 2009 through January 6, 2012, our former advisor supervised and managed our day-to-day operations and selected the properties and real estate-related investments we acquired, subject to the oversight and approval of our board of directors. Our former advisor also provided marketing, sales and client services on our behalf and engaged affiliated entities to provide various services to us. Our former advisor was managed by and was a wholly owned subsidiary of Grubb & Ellis Equity Advisors, LLC, or GEEA, which was a wholly owned subsidiary of Grubb & Ellis Company, or Grubb & Ellis, or our former sponsor.
	On November 7, 2011, our independent directors determined that it was in the best interests of our company and its stockholders to transition advisory and dealer manager services rendered to us by affiliates of Grubb & Ellis and to engage American Healthcare Investors LLC, or American Healthcare Investors, and Griffin Capital Corporation, or Griffin Capital, as replacement co-sponsors, or our co-sponsors. As a result, on November 7, 2011, we notified our former advisor that we terminated the G&E Advisory Agreement. Pursuant to the G&E Advisory Agreement, either party could terminate the G&E Advisory Agreement without cause or penalty; however, certain rights and obligations of the parties would survive during a 60-day transition period and beyond.
	In addition, on November 7, 2011, we notified Grubb & Ellis Capital Corporation, our former dealer manager, that we terminated the Amended and Restated Dealer Manager Agreement dated June 1, 2011 between us and Grubb & Ellis Capital Corporation, or the G&E Dealer Manager Agreement, in accordance with the terms thereof. Until January 6, 2012, Grubb & Ellis Capital Corporation remained a non-exclusive agent of our company and distributor of shares of our common stock.
	As a result of the co-sponsorship arrangement, an affiliate of Griffin Capital, Griffin-American Healthcare REIT Advisor, LLC, or Griffin-American Advisor, or our advisor, began serving as our advisor on January 7, 2012 pursuant to an advisory agreement, or the Advisory Agreement, that took effect upon the expiration of the 60-day transition period provided for in the G&E Advisory Agreement. The Advisory Agreement had a one-year term, but was subject to successive one year renewals upon mutual consent of the parties. The Advisory Agreement was renewed pursuant to the mutual consent of the parties and expires on January 7, 2014. Our advisor delegates advisory duties to Griffin-American Healthcare REIT Sub-Advisor, LLC, or Griffin-American Sub-Advisor, or our sub-advisor. Griffin-American Sub-Advisor is jointly owned by our co-sponsors. Our advisor, through our sub-advisor, uses its best efforts, subject to the oversight, review and approval of our board of directors, to, among other things, research, identify, review and make investments in and dispositions of properties, real estate-related investments and securities on our behalf consistent with our investment policies and objectives. Our advisor performs its duties and responsibilities under the Advisory Agreement as our fiduciary. Our sub-advisor performs its duties and responsibilities pursuant to a sub-advisory agreement with our advisor and also acts as our fiduciary. Collectively, we refer to our advisor and our sub-advisor as our advisor entities. Griffin Capital Securities, Inc., or Griffin Securities, or our dealer manager, an affiliate of Griffin Capital, serves as our dealer manager pursuant to a dealer manager agreement, or the Dealer Manager Agreement, that also became effective on January 7, 2012. We are not affiliated with Griffin Capital, Griffin-American Advisor or Griffin Securities; however, we are affiliated with Griffin-American Sub-Advisor and American Healthcare Investors.
	American Healthcare Investors and Griffin Capital paid the majority of the expenses we incurred in connection with the transition to our co-sponsors.
	We currently operate through four reportable business segments — medical office buildings, hospitals, skilled nursing facilities and senior housing. As of September 30, 2013, we had completed 67 acquisitions comprising 230 buildings and approximately 8,245,000 square feet of gross leasable area, or GLA, for an aggregate purchase price of approximately $2,230,836,000.

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	Summary of Significant Accounting Policies
	The summary of significant accounting policies presented below is designed to assist in understanding our condensed consolidated financial statements. Such condensed consolidated financial statements and the accompanying notes thereto are the representations of our management, who are responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States of America, or GAAP, in all material respects, and have been consistently applied in preparing our accompanying condensed consolidated financial statements.
	Basis of Presentation
	Our accompanying condensed consolidated financial statements include our accounts and those of our operating partnership, the wholly owned subsidiaries of our operating partnership and all non-wholly owned subsidiaries and any variable interest entities, or VIEs, as defined in Financial Accounting Standards Boards, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation, or ASC Topic 810, which we have concluded should be consolidated pursuant to ASC Topic 810. We operate and intend to continue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership, will own substantially all of the properties acquired on our behalf. We are the sole general partner of our operating partnership and as of September 30, 2013 and December 31, 2012, we own greater than a 99.90% and 99.96%, respectively, general partnership interest therein. On January 4, 2012, our advisor contributed $2,000 to acquire 200 limited partnership units of our operating partnership and as such, as of September 30, 2013 and December 31, 2012, owns less than a 0.01% noncontrolling limited partnership interest in our operating partnership. Between December 31, 2012 and July 16, 2013, 12 investors contributed their interests in 15 buildings in exchange for 281,600 limited partnership units in our operating partnership. As of September 30, 2013 and December 31, 2012, these investors collectively owned 281,600 and 42,700 limited partnership units, respectively, which represented less than a 0.10% and 0.04%, respectively, noncontrolling limited partnership interest in our operating partnership. Because we are the sole general partner and a limited partner of our operating partnership and have unilateral control over its management and major operating decisions, the accounts of our operating partnership are consolidated in our condensed consolidated financial statements. All significant 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 2012 Annual Report on Form 10-K, as filed with the SEC on March 15, 2013.
	Use of Estimates
	The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. 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 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 to meet the contractual obligations under their lease agreements. We maintain an allowance for deferred rent receivables arising from the straight line recognition of rents. Such allowance is charged to bad debt expense which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant's financial condition, security deposits, letters of credit, lease guarantees and current economic conditions and other relevant factors.
	As of September 30, 2013 and December 31, 2012, we had $289,000 and $78,000, respectively, in allowance for uncollectible accounts which was determined necessary to reduce receivables to our estimate of the amount recoverable. For the three months ended September 30, 2013 and 2012, we recovered $43,000 and $0, respectively, net, of our receivables that had previously been written off to bad debt expense. For the nine months ended September 30, 2013 and 2012, $48,000 and $0, respectively, net, of our receivables were directly written off to bad debt expense. For the three months ended September 30, 2013 and 2012, none of our receivables, and for the nine months ended September 30, 2013 and 2012, $25,000 and $0, respectively, of our receivables were written off against the allowance for uncollectible accounts. As of September 30, 2013 and December 31, 2012, we did not have an allowance for uncollectible accounts for deferred rent receivables. For the three months ended September 30, 2013 and 2012, $26,000 and $1,000, respectively, and for the nine months ended September 30, 2013 and 2012, $44,000 and $9,000, respectively, of our deferred rent receivables were directly written off to bad debt expense.
	Other Liabilities
	As of September 30, 2013 and December 31, 2012, included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets was $5,453,000 and $60,204,000, respectively, of contingent consideration obligations in connection with our property acquisitions. Such amounts are due upon certain criteria being met within specified timeframes. For the three months ended September 30, 2013 and 2012, we recorded a net gain (loss) on the change in fair value of contingent consideration of $0 and $(12,446,000), respectively, and for the nine months ended September 30, 2013 and 2012, we recorded a net (loss) on the change in fair value of contingent consideration of $(273,000) and $(12,048,000), respectively, which is included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). See Note 14, Fair Value Measurements — Assets and Liabilities Reported at Fair Value — Contingent Consideration, for a further discussion.
	Also included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets as of September 30, 2013 is a foreign deferred tax liability of approximately £33,100,000 (or approximately $53,573,000 based on the currency exchange rate as of September 30, 2013) related to the temporary difference between the book basis and the tax basis of our real estate investment assets in the United Kingdom. We measure deferred tax liabilities using enacted tax rates as of the end of each reporting period. The deferred tax liability will be remeasured at each reporting period until it is fully recognized and any change in the liability will be recorded in our accompanying condensed consolidated statements of operations and comprehensive income (loss) in the period of change.
	Subordinated Distribution Purchase
	On September 14, 2012, we and our operating partnership entered into an agreement, or the settlement agreement, with BGC Partners, Inc., or BGC Partners, which held 200 units of limited partnership interest in our operating partnership and would have been entitled to any subordinated distribution that would have been owed to our former advisor and its affiliates, including our former sponsor. Pursuant to the settlement agreement, BGC Partners transferred certain assets to us, including the 200 units of limited partnership interest held in our operating partnership and any rights to the payment of any subordinated distribution for consideration of $4,300,000. Notwithstanding these transfers to us, in the event of a listing event or other liquidity event, as both terms are defined in the partnership agreement for our operating partnership, or the operating partnership agreement, we will calculate a hypothetical deferred termination amount (as defined in the operating partnership agreement and based on assets acquired by us on or before January 10, 2012) for the payment of the subordinated distribution that would have been owed to our former advisor and its affiliates, including our former sponsor. If such calculation results in an amount that is greater than the $4,300,000 paid by us, then we will pay BGC Partners an amount equal to 10.0% of the difference between such calculation and the $4,300,000 paid by us. In connection with the settlement agreement, BGC Partners has agreed to release all known and unknown claims that they may have had against us and our operating partnership.
	Of the $4,300,000 paid by us, $4,232,000 is reflected in our accompanying condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2012 and $68,000 is in satisfaction of all remaining payments owed by us to our former advisor and its affiliates, including our former sponsor, under the G&E Advisory Agreement.
	Segment Disclosure
	ASC Topic 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity's reportable segments. As of September 30, 2013, we operated through four reportable business segments — medical office buildings, hospitals, skilled nursing facilities and senior housing. Prior to June 2013, our senior housing segment was referred to as our assisted living facilities segment. Prior to August 2012, we operated through three reportable business segments; however, with the addition of our first senior housing facilities in August 2012, we felt it was useful to segregate our operations into these four reporting segments to assess the performance of our business in the same way that management intends to review our performance and make operating decisions.
	See Note 16, Segment Reporting, for a further discussion.
	Foreign Currency
	We have real estate investments in the United Kingdom for which the functional currency is the United Kingdom Pound Sterling, or GBP. We translate the results of operations of our foreign real estate investments into U.S. Dollars, or USD, using the average rates of exchange in effect during the period, and we translate assets and liabilities using the currency exchange rate in effect at the end of the period. The resulting foreign currency translation adjustments are included in accumulated other comprehensive income, or AOCI, a component of stockholders' equity in our accompanying condensed consolidated balance sheets.
	Gains or losses resulting from foreign currency transactions are remeasured into USD at the rates of exchange prevailing on the date of the transactions. The effects of transaction gains/losses are generally included in foreign currency and derivative loss in our condensed consolidated statements of operations and comprehensive income (loss). In addition to the unrealized loss we recorded on our foreign currency forward contract, we recorded $4,971,000 and $4,641,000 for the three and nine months ended September 30, 2013, respectively, in foreign currency transaction gains. See Note 8, Derivative Financial Instruments — Foreign Currency Forward Contract, for a further discussion of our foreign currency forward contract.
	Reclassifications
	Deferred rent for the nine months ended September 30, 2012 has been reclassified on our accompanying condensed consolidated statements of cash flows to conform to the current year presentation. This reclassification has no effect on cash flows provided by operating activities.
	Recently Issued Accounting Pronouncements
	In February 2013, the FASB issued Accounting Standards Update, or ASU, 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, or ASU 2013-02, to improve the transparency of amounts reclassified out of AOCI. The additional disclosure requirements in ASU 2013-02 include: (1) changes in AOCI balances by component and (2) presentation of significant amounts reclassified out of AOCI to net income (loss) by the specific line item of net income (loss)affected. For public entities, ASU 2013-02 is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. We adopted ASU 2013-02 on January 1, 2013, which did not have a material impact on our consolidated financial statements.

For the three months ended September 30, 2013 and 2012, we had capital expenditures of $1,700,000 and $1,534,000, respectively, on our medical office buildings, and $0 and $398,000, respectively, on our skilled nursing facilities. We did not have any capital expenditures on our senior housing facilities or our hospitals for the three months ended September 30, 2013 and 2012.
	Depreciation expense for the nine months ended September 30, 2013 and 2012 was $33,754,000 and $16,839,000, respectively. For the nine months ended September 30, 2013 and 2012, we had capital expenditures of $3,515,000 and $3,155,000, respectively, on our medical office buildings, $0 and $905,000, respectively, on our skilled nursing facilities and $3,000 and $0, respectively, on our senior housing facilities. We did not have any capital expenditures on our hospitals for the nine months ended September 30, 2013 and 2012. In addition, subsequent to the initial purchase of Dixie-Lobo Medical Office Building Portfolio, on May 2, 2013, we purchased the land under the building in Hope, Arkansas for a purchase price of $50,000 plus closing costs and acquisition fees, for which we previously owned a leasehold interest.
	Until January 6, 2012, we reimbursed our former advisor or its affiliates and since January 7, 2012, we reimburse our advisor entities or their affiliates for acquisition expenses related to selecting, evaluating, acquiring and investing in properties. 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. For the three and nine months ended September 30, 2013 and 2012, such fees and expenses did not exceed 6.0% of the purchase price of our acquisitions, except with respect to our acquisition of land in the Dixie-Lobo Medical Office Building Portfolio noted above. Pursuant to our charter, prior to the acquisition of the land in the Dixie-Lobo Medical Office Building Portfolio, our directors, including a majority of our independent directors, not otherwise interested in the transaction, approved the fees and expenses associated with the acquisition of the land in excess of the 6.0% limit and determined that such fees and expenses were commercially competitive, fair and reasonable to us.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	ASC Topic 815, Derivatives and Hedging, or ASC Topic 815, establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. We utilize derivatives such as fixed interest rate swaps to add stability to interest expense and to manage our exposure to interest rate movements. We also use derivative instruments, such as foreign currency forward contracts, to mitigate the effects of the foreign currency fluctuations on future cash flows. 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).
	As of September 30, 2013, no derivatives were designated as hedges. Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and foreign currency fluctuations, but do not meet the strict hedge accounting requirements of 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 income (loss). Changes in the fair value of foreign currency derivative financial instruments are recorded in foreign currency and derivative loss in our accompanying condensed consolidated statements of operations and comprehensive income (loss).

On June 5, 2012, we terminated and currently have no additional obligations under the KeyBank line of credit.
	Unsecured Revolving Line of Credit
	On June 5, 2012, we, our operating partnership and certain of our subsidiaries, or the subsidiary guarantors, entered into a credit agreement, or the Credit Agreement, with Bank of America, as administrative agent, swingline lender and issuer of letters of credit; KeyBank, as syndication agent; Merrill Lynch, Pierce, Fenner & Smith Incorporated and KeyBanc Capital Markets as joint lead arrangers and joint book managers; and the lenders named therein, to obtain an unsecured revolving line of credit, with an aggregate maximum principal amount of $200,000,000, or the unsecured line of credit. On June 5, 2012 and June 7, 2012, we also entered into separate revolving notes, or the Revolving Notes, with each of Bank of America, KeyBank, Comerica Bank and RBS Citizens, N.A., whereby we promised to pay the principal amount of each revolving loan and accrued interest to the respective lender or its registered assigns, in accordance with the terms and conditions of the Credit Agreement. The proceeds of loans made under the unsecured line of credit may be used for working capital, capital expenditures and other general corporate purposes (including, without limitation, property acquisitions and repayment of debt). Our operating partnership may obtain up to 10.0% of the maximum principal amount in the form of standby letters of credit and up to 15.0% of the maximum principal amount in the form of swingline loans.
	On May 24, 2013, we entered into a Second Amendment to the Credit Agreement, or the Amendment, which increased the aggregate maximum principal amount of the unsecured line of credit to $450,000,000, with Bank of America, KeyBank National Association, RBS Citizens, N.A., and Comerica Bank, as existing lenders, and Barclays Bank PLC, Fifth Third Bank, Wells Fargo Bank, N.A., Credit Agricole Corporate and Investment Bank, and Sumitomo Mitsui Banking Corporation, as new lenders. The Amendment also revised the amount that may be obtained by our operating partnership in the form of swingline loans from up to 15.0% of the maximum principal amount to up to $50,000,000. On May 24, 2013, we also entered into separate revolving notes with each of Bank of America, KeyBank, RBS Citizens, N.A., Comerica Bank, Barclays Bank PLC, Fifth Third Bank, Wells Fargo Bank, N.A., Credit Agricole Corporate and Investment Bank, and Sumitomo Mitsui Banking Corporation whereby we promised to pay the principal amount of each revolving loan and accrued interest to the respective lender or its registered assigns, in accordance with the terms and conditions of the Credit Agreement.
	The maximum principal amount of the Credit Agreement, as amended, may be increased by up to $200,000,000, for a total principal amount of $650,000,000, subject to (a) the terms of the Credit Agreement, as amended, and (b) such additional financing amount being offered and provided by existing lenders or new lenders under the Credit Agreement, as amended.
	At our option, loans under the Credit Agreement, as amended, bear interest at per annum rates equal to (a) (i) the Eurodollar Rate plus (ii) a margin ranging from 2.00% to 3.00% based on our consolidated leverage ratio, or (b) (i) the greater of: (x) the prime rate publicly announced by Bank of America, (y) the Federal Funds Rate (as defined in the Credit Agreement, as amended) plus 0.50% and (z) the one-month Eurodollar Rate (as defined in the Credit Agreement, as amended) plus 1.00%, plus (ii) a margin ranging from 1.00% to 2.00% based on our consolidated leverage ratio. Accrued interest under the Credit Agreement, as amended, is payable monthly. The unsecured line of credit matures on June 5, 2015, and may be extended by one 12-month period subject to satisfaction of certain conditions, including payment of an extension fee.
	We are required to pay a fee on the unused portion of the lenders' commitments under the Credit Agreement, as amended, at a per annum rate equal to 0.25% if the average daily used amount is greater than 50.0% of the commitments and 0.35% if the average daily used amount is less than 50.0% of the commitments.
	The Credit Agreement, as amended, contains various affirmative and negative covenants that are customary for credit facilities and transactions of this type, including limitations on the incurrence of debt by our operating partnership and its subsidiaries and limitations on secured recourse indebtedness. The Credit Agreement, as amended, imposes the following financial covenants, which are specifically defined in the Credit Agreement, as amended: (a) a maximum consolidated leverage ratio; (b) a maximum consolidated secured leverage ratio; (c) a minimum consolidated tangible net worth covenant; (d) a minimum consolidated fixed charge coverage ratio; (e) a maximum dividend payout ratio; (f) a maximum consolidated unencumbered leverage ratio; and (g) a minimum consolidated unencumbered interest coverage ratio. As of September 30, 2013 and December 31, 2012, we were in compliance with all such covenants and requirements.
	The Credit Agreement, as amended, requires us to add additional subsidiaries as guarantors in the event the value of the assets owned by the subsidiary guarantors falls below a certain threshold as set forth in the Credit Agreement, as amended. In the event of default, Bank of America has the right to terminate its obligations under the Credit Agreement, as amended, including the funding of future loans, and to accelerate the payment on any unpaid principal amount of all outstanding loans and interest thereon.
	The actual amount of credit available under the unsecured line of credit at any given time is a function of, and is subject to, loan to value and debt service coverage ratios based on net operating income as contained in the Credit Agreement, as amended. Based on the value of our borrowing base properties, as such term is used in the Credit Agreement, as amended, our aggregate borrowing capacity under the unsecured line of credit was $450,000,000 and $200,000,000, respectively, as of September 30, 2013 and December 31, 2012. As of September 30, 2013, there were no borrowings outstanding under the unsecured line of credit and $450,000,000 remained available under the unsecured line of credit. As of December 31, 2012, borrowings outstanding under the unsecured line of credit totaled $200,000,000 and $0 remained available under the unsecured line of credit. The weighted average interest rate on borrowings outstanding as of December 31, 2012 was 3.33% per annum.

	Commitments and Contingencies
	Litigation
	We are not presently subject to any material litigation nor, to our knowledge, is any material litigation threatened against us, which if determined unfavorably to us, would have a material adverse effect on our condensed consolidated financial position, results of operations or cash flows.
	Environmental Matters
	We follow a policy of monitoring our properties for the presence of hazardous or toxic substances. While there can be no assurance that a material environmental liability does not exist at our properties, we are not currently aware of any environmental liability with respect to our properties that would have a material effect on our condensed consolidated financial position, results of operations or cash flows. Further, we are not aware of any material environmental liability or any unasserted claim or assessment with respect to an environmental liability that we believe would require additional disclosure or the recording of a loss contingency.
	Other Organizational and Offering Expenses
	During the period from January 7, 2012 until February 14, 2013, our other organizational and offering expenses in connection with our initial offering (other than selling commissions and the dealer manager fee) were paid by our sub-advisor or its affiliates on our behalf. Prior to January 7, 2012, other organizational and offering expenses were paid by our former advisor or its affiliates. Other organizational and offering expenses included all expenses (other than selling commissions and the dealer manager fee which generally represent 7.0% and 3.0%, respectively, of our gross offering proceeds) to be paid by us in connection with our initial offering. These other organizational and offering expenses would only have become our liability to the extent they did not exceed 1.0% of the gross 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. As of February 14, 2013 and December 31, 2012, our sub-advisor, our former advisor and their affiliates had not incurred expenses on our behalf in excess of 1.0% of the gross proceeds of our initial offering. We terminated our initial offering and commenced our follow-on offering on February 14, 2013.
	Our other organizational and offering expenses incurred in connection with our follow-on offering were paid by our sub-advisor or its affiliates on our behalf. These other organizational and offering expenses included all expenses (other than selling commissions and the dealer manager fee) to be paid by us in connection with our follow-on offering. These expenses only became our liability to the extent these other organizational and offering expenses did not exceed 1.0% of the gross offering proceeds from the sale of shares of our common stock in our follow-on offering. As of December 31, 2012, our sub-advisor and its affiliates had incurred expenses on our behalf of $610,000, in excess of 1.0% of the gross proceeds related to our follow-on offering, and therefore, these expenses were not recorded in our accompanying condensed consolidated financial statements as of December 31, 2012. As of September 30, 2013, our sub-advisor and its affiliates had not incurred expenses on our behalf in excess of 1.0% of the gross proceeds of our follow-on offering. On October 30, 2013, we terminated our follow-on offering.
	When recorded by us, other organizational expenses will be expensed as incurred, and offering expenses are charged to stockholders' equity as such amounts are reimbursed to our former advisor, our sub-advisor or their affiliates from the gross proceeds of our initial offering or our follow-on offering, or our offerings. See Note 12, Related Party Transactions — Offering Stage, for a further discussion of other organizational and offering expenses.
	Other
	Our other commitments and contingencies include the usual obligations of real estate owners and operators in the normal course of business, which include calls/puts to sell/acquire properties.

	Fees and Expenses Paid to Affiliates
	Until January 6, 2012, all of our executive officers and our non-independent directors were also executive officers and employees and/or holders of a direct or indirect interest in our former advisor, our former sponsor, GEEA or other affiliated entities.
	Effective as of August 24, 2009, we entered into the G&E Advisory Agreement with our former advisor, and effective as of June 22, 2009, we entered into the G&E Dealer Manager Agreement with Grubb & Ellis Securities, Inc., or Grubb & Ellis Securities. Until April 18, 2011, Grubb & Ellis Securities served as the dealer manager of our initial offering pursuant to the G&E Dealer Manager Agreement. Effective as of April 19, 2011, the G&E Dealer Manager Agreement with Grubb & Ellis Securities was assigned to, and assumed by, Grubb & Ellis Capital Corporation, a wholly owned subsidiary of our former sponsor. Therefore, references to the G&E Dealer Manager shall be deemed to refer to either Grubb & Ellis Securities or Grubb & Ellis Capital Corporation, or both, as applicable, unless otherwise specified.
	On November 7, 2011, we notified our former advisor of the termination of the G&E Advisory Agreement. Pursuant to the G&E Advisory Agreement, either party could terminate the G&E Advisory Agreement without cause or penalty, subject to a 60-day transition period; however, certain rights and obligations of the parties would survive during the 60-day transition period and beyond. As a result of a new advisory agreement that took effect on January 7, 2012 upon the expiration of the 60-day transition period provided for in the G&E Advisory Agreement, Griffin-American Advisor serves as our advisor and delegates advisory duties to Griffin-American Sub-Advisor.
	In addition, on November 7, 2011, we notified Grubb & Ellis Capital Corporation of the termination of the G&E Dealer Manager Agreement. Pursuant to the G&E Dealer Manager Agreement, either party could terminate the G&E Dealer Manager Agreement, subject to a 60-day transition period. Until January 6, 2012, Grubb & Ellis Capital Corporation remained a non-exclusive agent of our company and distributor of shares of our common stock. As a result of the Dealer Manager Agreement that took effect on January 7, 2012 upon the expiration of the 60-day transition period provided for in the G&E Dealer Manager Agreement, Griffin Securities serves as our dealer manager. The terms of the Dealer Manager Agreement are substantially the same as the terms of the terminated G&E Dealer Manager Agreement.
	Upon the termination of the G&E Advisory Agreement and G&E Dealer Manager Agreement and corresponding 60-day transition periods, after January 6, 2012, we are no longer affiliated with Grubb & Ellis and its affiliates. The G&E Advisory Agreement and the G&E Dealer Manager Agreement entitled our former advisor, G&E Dealer Manager and their affiliates to specified compensation for certain services, as well as reimbursement of certain expenses. In the aggregate, for the three and nine months ended September 30, 2012, we incurred $0 and $5,481,000, respectively, in fees and expenses paid to our former advisor or its affiliates as detailed below.
	We are affiliated with Griffin-American Sub-Advisor and American Healthcare Investors; however, we are not affiliated with Griffin Capital, Griffin-American Advisor or Griffin Securities. In the aggregate, for the three months ended September 30, 2013 and 2012, we incurred $24,062,000 and $11,642,000, respectively, and for the nine months ended September 30, 2013 and 2012, we incurred $41,840,000 and $22,933,000, respectively, in fees and expenses paid to our affiliates as detailed below. As discussed above, our advisor, which is not our affiliate, delegates certain advisory duties pursuant to a sub-advisory agreement to our sub-advisor, which is our affiliate. Therefore, although certain obligations under the Advisory Agreement are contractually performed by or for our advisor, only such obligations pursuant to the sub-advisory agreement that are performed by or for our sub-advisor or its affiliates are disclosed in this related party transactions note.

	Effective as of January 7, 2012, our sub-advisor or its affiliates are paid a monthly fee for services rendered in connection with the management of our assets equal to one-twelfth of 0.85% of average invested assets existing as of January 6, 2012 and one-twelfth of 0.75% of the average invested assets acquired after January 6, 2012, subject to our stockholders receiving distributions in an amount equal to 5.0% per annum, cumulative, non-compounded, of average 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 average 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, 2013 and 2012, we incurred $3,392,000 and $1,794,000, respectively, and for the nine months ended September 30, 2013 and 2012, we incurred $9,121,000 and $4,438,000, respectively, in asset management fees to our sub-advisor.

In addition to the above property management fee, for each property managed directly by entities other than our sub-advisor or its affiliates, we pay our sub-advisor or its affiliates a monthly oversight fee of up to 1.0% of the gross cash receipts from the property; provided however, that in no event will we pay both a property management fee and an oversight fee to our sub-advisor or its affiliates with respect to the same property.

Such fee is generally expected to range from 3.0% to 8.0% of the gross revenues generated during the initial term of the lease.

	Effective as of January 7, 2012, we reimburse our sub-advisor or its affiliates for operating expenses incurred in rendering services to us, subject to certain limitations. However, we cannot reimburse our sub-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.
	For the 12 months ended September 30, 2013, our operating expenses did not exceed this limitation. Our operating expenses as a percentage of average invested assets and as a percentage of net income were 1.0% and 35.9%, respectively, for the 12 months ended September 30, 2013.

	Related Party Services Agreement

Since our former transfer agent was an affiliate of our former advisor, the terms of the Transfer Agent Services Agreement were approved and determined by a majority of our directors, including a majority of our independent directors, as fair and reasonable to us and at fees which are no greater than that which would be paid to an unaffiliated party for similar services.
	On November 7, 2011, we provided notice of termination of the Transfer Agent Services Agreement to our former transfer agent. Under the Transfer Agent Services Agreement, we were required to provide 60 days written notice of termination. Therefore, the Transfer Agent Services Agreement terminated on January 6, 2012. We engaged DST Systems, Inc., an unaffiliated party, to serve as our replacement transfer agent on January 6, 2012.
	For the three and nine months ended September 30, 2012, we incurred expenses of $0 and $10,000, respectively, for investor services that our former transfer agent provided to us, which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss).
For the three and nine months ended September 30, 2012, GEEA incurred expenses of $0 and $2,000, respectively, for subscription agreement processing services that our former transfer agent provided to us. As an other organizational and offering expense, these subscription agreement processing expenses became our liability since cumulative other organizational and offering expenses did not exceed 1.0% of the gross 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.
Compensation for Additional Services
Effective as of January 7, 2012, our sub-advisor and its affiliates are paid for services performed for us other than those required to be rendered by our sub-advisor or its affiliates under the Advisory Agreement.

	Common Stock
	Our charter authorizes us to issue 1,000,000,000 shares of our common stock. Until November 6, 2012, we offered to the public up to $3,000,000,000 of shares of our common stock for $10.00 per share in our primary offering and $285,000,000 of shares of our common stock pursuant to our DRIP for $9.50 per share. On November 7, 2012, we began selling shares of our common stock in our initial offering at $10.22 per share in our primary offering and issuing shares pursuant to the DRIP for $9.71 per share. On February 14, 2013, we terminated our initial offering.
	On February 14, 2013, we commenced our follow-on offering of up to $1,650,000,000 of shares of our common stock, in which we initially offered to the public up to $1,500,000,000 of shares of our common stock for $10.22 per share in our primary offering and up to $150,000,000 of shares of our common stock for $9.71 per share pursuant to the DRIP. We reserved the right to reallocate the shares of common stock we offered in our follow-on offering between the primary offering and the DRIP. As such, during our follow-on offering, we reallocated an aggregate $107,200,000 of shares from the DRIP to the primary offering. Accordingly, we offered to the public $1,607,200,000 in our primary offering and $42,800,000 of shares of our common stock pursuant to the DRIP. On October 30, 2013, we terminated our follow-on offering. See Note 19, Subsequent Events — Status of our Follow-On Offering, for a further discussion.
	On September 9, 2013, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, to register a maximum of $100,000,000 of additional shares of our common stock pursuant to the Secondary DRIP. 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 until October 30, 2013 following the termination of our follow-on offering.
	On February 4, 2009, our former advisor purchased 20,000 shares of common stock for total cash consideration of $200,000 and was admitted as our initial stockholder. We used the proceeds from the sale of shares of our common stock to our former advisor to make an initial capital contribution to our operating partnership. We subsequently repurchased the 20,000 shares of our common stock from our former advisor in February 2012 in connection with our transition to our co-sponsors.

On January 4, 2012, Griffin-American Advisor contributed $2,000 to acquire 200 limited partnership units of our operating partnership.

Between December 31, 2012 and July 16, 2013, 12 investors contributed their interests in 15 buildings in exchange for 281,600 limited partnership units in our operating partnership.

As such, 1.25% of the earnings of the Pocatello East MOB property were allocated to noncontrolling interests.
	Distribution Reinvestment Plan
	We adopted the DRIP that allows 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 offerings, subject to certain conditions. For the three months ended September 30, 2013 and 2012, $18,500,000 and $5,972,000, respectively, in distributions were reinvested and 1,905,291 and 628,606 shares of our common stock, respectively, were issued pursuant to the DRIP. For the nine months ended September 30, 2013 and 2012, $41,330,000 and $14,621,000, respectively, in distributions were reinvested and 4,256,434 and 1,539,068 shares of our common stock, respectively, were issued pursuant to the DRIP. As of September 30, 2013 and December 31, 2012, a total of $74,754,000 and $33,424,000, respectively, in distributions were reinvested and 7,767,854 and 3,511,420 shares of our common stock, respectively, were issued pursuant to the DRIP.
	On September 9, 2013, we filed a Registration Statement on Form S-3 under the Securities Act of 1933, as amended, to register a maximum of $100,000,000 of additional shares of our common stock pursuant to the Secondary DRIP. We commenced offering shares under the Secondary DRIP on October 30, 2013 following the termination of our follow-on offering.
	Share Repurchase Plan
	Our board of directors 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 of directors. All repurchases are 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. 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.
	Until December 7, 2012, under our share repurchase plan, repurchase prices ranged from $9.25, or 92.5% of the price paid per share, following a one-year holding period to an amount not less than 100% of the price paid per share following a four-year holding period. On November 6, 2012, our board of directors approved an Amended and Restated Share Repurchase Plan, whereby all shares repurchased on or after December 7, 2012 would be repurchased at 92.5% to 100% of each stockholder's repurchase amount depending on the period of time their shares have been held. Pursuant to the Amended and Restated Share Repurchase Plan, at any time we are engaged in an offering of shares of our common stock, the repurchase amount for shares repurchased under our share repurchase plan will always be equal to or lower than the applicable per share offering price. However, if shares of our common stock are to be repurchased in connection with a stockholder's death or qualifying disability, the repurchase price will be no less than 100% of the price paid to acquire the shares of our common stock from us. 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, 2013 and 2012, we received share repurchase requests and repurchased 226,123 and 75,396 shares of our common stock, respectively, for an aggregate of $2,186,000 and $727,000, respectively, at an average repurchase price of $9.67 and $9.64 per share, respectively. For the nine months ended September 30, 2013 and 2012, we received share repurchase requests and repurchased 770,798 and 241,836 shares of our common stock, respectively, for an aggregate of $7,440,000 and $2,341,000, respectively, at an average repurchase price of $9.65 and $9.68 per share, respectively. All shares were repurchased using proceeds we received from the sale of shares of our common stock pursuant to the DRIP.
	As of September 30, 2013 and December 31, 2012, we had received share repurchase requests and had repurchased 1,326,937 shares of our common stock for an aggregate of $12,801,000 at an average price of $9.65 per share and 556,139 shares of our common stock for an aggregate of $5,361,000 at an average price of $9.64, respectively, using proceeds we received from the sale of shares of our common stock pursuant to the DRIP.
	2009 Incentive Plan
	We adopted our incentive plan, pursuant to which our board of directors or a committee of our independent directors may make grants of options, restricted shares of 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.
	On October 21, 2009, we granted an aggregate of 15,000 shares of our restricted common stock, as defined in our incentive plan, to our independent directors in connection with their initial election to our board of directors, of which 20.0% vested on the grant date and 20.0% will vest on each of the first four anniversaries of the date of grant. On each of June 8, 2010, June 14, 2011 and November 7, 2012, in connection with their re-election, we granted an aggregate of 7,500, 7,500 and 15,000 shares, respectively, of our restricted common stock, as defined in our incentive plan, to our independent directors, which will vest over the same period described above. In addition, on November 7, 2012, we granted an aggregate of 7,500 shares of restricted common stock, as defined in our incentive plan, to our independent directors, in consideration of the directors' determination of market compensation for independent directors of similar publicly registered real estate investment trusts, which will vest under the same period described above. The fair value of each share at the date of grant was estimated at $10.00 or $10.22 per share, as applicable, the then current offering price of shares of our common stock; and with respect to the initial 20.0% of shares of our restricted common stock that vested on the date of grant, expensed as compensation immediately, and with respect to the remaining shares of our restricted common stock, amortized on a straight-line basis over the vesting period. 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. For the three months ended September 30, 2013 and 2012, we recognized compensation expense of $27,000 and $15,000, respectively, and for the nine months ended September 30, 2013 and 2012, we recognized compensation expense of $80,000 and $48,000, respectively, related to the restricted common stock grants ultimately expected to vest. 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, 2013 and 2012, we did not assume any forfeitures. Stock compensation expense is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss).
	As of September 30, 2013 and December 31, 2012, there was $180,000 and $260,000, respectively, of total unrecognized compensation expense, net of estimated forfeitures, related to nonvested shares of our restricted common stock. This expense is expected to be recognized over a remaining weighted average period of 2.44 years.
	As of September 30, 2013 and December 31, 2012, the weighted average grant date fair value of the nonvested shares of our restricted common stock was $259,000 and $289,000, respectively. A summary of the status of the nonvested shares of our restricted common stock as of September 30, 2013 and December 31, 2012, and the changes for the nine months ended September 30, 2013, is presented below:
		Number of Nonvested		Weighted

	There were no transfers into and out of fair value measurement levels during the nine months ended September 30, 2013 and 2012.
	Derivative Financial Instruments
	We use interest rate swaps to manage interest rate risk associated with floating rate debt and foreign currency forward contracts to mitigate the effects of foreign currency fluctuations. 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, spot and forward rates, as well as option volatility. The fair values of interest rate swaps and foreign currency forward contracts are determined using the market standard methodology of 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 or foreign currency exchange rates (forward curves) derived from observable market interest rate curves and foreign currency exchange rate curves, as applicable.
	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 interest rate swaps and foreign currency forward contracts 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, 2013 and December 31, 2012, 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 interest rate swaps and foreign currency forward contracts. As a result, we have determined that our interest rate swaps and foreign currency forward contracts valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	Contingent Consideration
	Assets
	On December 22, 2011, we purchased Sierra Providence East Medical Plaza I and, in connection with such purchase, we recognized $115,000 as a contingent consideration asset as of December 31, 2011. We would have received such consideration to the extent a tenant in approximately 2,000 square feet of GLA did not pay their rental payments to us over the remaining term of their lease, which would have expired in April 2014. The range of payment to us was between $0 and up to a maximum of $115,000. In May 2012, a new tenant assumed the existing lease and pursuant to the agreement with the seller, we received $2,000 and the remaining funds held in escrow of $113,000 were released to the seller.
	Obligations
	In connection with our property acquisitions, we have accrued $5,453,000 and $60,204,000 as contingent consideration obligations as of September 30, 2013 and December 31, 2012, respectively. Such consideration will be paid upon various conditions being met, including our tenants achieving certain rent coverage ratios, completing renovation projects or sellers' leasing of unoccupied space. Of the amount accrued as of December 31, 2012, $52,585,000 relates to our acquisition of Philadelphia SNF Portfolio on June 30, 2011, $5,492,000 relates to our acquisition of Pacific Northwest Senior Care Portfolio on August 24, 2012 and $2,127,000 relates to various other property acquisitions. Of the amount accrued as of September 30, 2013, $3,750,000 relates to our acquisition of Pacific Northwest Senior Care Portfolio and $1,703,000 relates to various other property acquisitions.
	We recorded an increase in the obligation related to Philadelphia SNF Portfolio of $458,000 for the nine months ended September 30, 2013. For the nine months ended September 30, 2013, we paid $53,043,000 to settle obligations related to our acquisition of Philadelphia SNF Portfolio. Such payments resulted in an increase in the monthly rent charged to the tenant and additional rental revenue to us.
	We could be required to pay up to $6,525,000 in contingent consideration with respect to our acquisition of Pacific Northwest Senior Care Portfolio. The first $4,700,000 of such contingent consideration can be paid immediately following the acquisition date upon notification that improvements up to such dollar amount have been completed by the tenant. The remaining portion of up to $1,825,000 could be paid within three years from the acquisition date provided that (i) the tenant has achieved a certain specified rent coverage ratio computed in the aggregate for the six most recent calendar months and (ii) the tenant has completed additional improvements in an amount up to $1,825,000. The range of payment is between $0 and up to a maximum of $6,525,000; however, such payment will result in an increase in the monthly rent charged to the tenant and additional rental revenue to us. We have assumed that the tenant will use and request the first $4,700,000 for the improvements and that the tenant will achieve the required rent coverage ratios for six consecutive months to qualify for the additional $1,825,000. As of September 30, 2013, we have made payments of $2,775,000 towards this obligation.
	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. Our contingent consideration assets are included in other assets, net and our contingent consideration obligations are included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets and any changes in their fair value 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 income (loss).
	The following table shows quantitative information about unobservable inputs related to Level 3 fair value measurements used as of September 30, 2013 for our most significant contingent consideration obligation:
	Property		Fair Value as of September 30, 2013			Unobservable Inputs		Range of Inputs/Inputs
	Pacific Northwest Senior Care Portfolio		$	3,750,000		Achieve Required Lease Coverage Ratios		Yes
						Total Estimated Cost of Tenant Improvements		$6,525,000
						Percentage of Eligible Payment Requested		100%
	Significant increases or decreases in any of the unobservable inputs in isolation or aggregate would result in a significantly higher or lower fair value measurement to each contingent consideration obligation as of September 30, 2013. Lastly, if the counterparty requests something less than 100% of the eligible payment, which they have the right to do so, then the fair value would decrease. If the lease coverage ratio for Pacific Northwest Senior Care Portfolio is not met, then the fair value would decrease to $1,925,000. A decrease in the total cost of the tenant improvements would decrease the fair value of the tenant improvement allowance. An increase in the total cost of the tenants improvements would have no impact on the payment.
	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 ended September 30, 2013 and 2012:

	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, net, cash and cash equivalents, accounts and other receivables, net, restricted cash, real estate and escrow deposits, accounts payable and accrued liabilities, accounts payable due to affiliates, mortgage loans payable, net and borrowings under the unsecured line of credit.
	We consider the carrying values of real estate notes receivable, net, cash and cash equivalents, accounts and other receivables, net, restricted cash, real estate and escrow deposits, accounts payable and accrued liabilities to approximate the fair value for these financial instruments because of the short period of time between origination of the instruments and their expected realization. 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 mortgage loans payable and the unsecured line of credit is estimated using a discounted cash flow analysis using borrowing rates available to us for debt instruments with similar terms and maturities. As of September 30, 2013 and December 31, 2012, the fair value of the mortgage loans payable was $339,931,000 and $308,472,000, respectively, compared to the carrying value of $343,186,000 and $291,052,000, respectively. The fair value of the unsecured line of credit as of September 30, 2013 and December 31, 2012 was $0 and $199,780,000, respectively, compared to the carrying value of $0 and $200,000,000, respectively. We have determined that the mortgage loans payable and the unsecured line of credit valuations are classified as Level 2 within the fair value hierarchy.

	2013
	For the nine months ended September 30, 2013, we completed 15 property acquisitions comprising 34 buildings. The aggregate purchase price was $284,000,000, plus closing costs and acquisition fees of $8,775,000, which are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). See Note 3, Real Estate Investments, Net, for a listing of the properties acquired, acquisition dates and the amount of financing initially incurred or assumed in connection with such acquisitions.
	Results of operations for the property acquisitions are reflected in our accompanying condensed consolidated statements of operations and comprehensive income (loss) for the nine months ended September 30, 2013 for the period subsequent to the acquisition date of each property through September 30, 2013. For the period from the acquisition date through September 30, 2013, we recognized the following amounts of revenue and net income for the property acquisitions:
	Acquisition		Revenue				Net Income
	2013 Acquisitions		$	12,200,000			$	1,611,000
	The following summarizes the fair value of our 2013 property acquisitions at the time of acquisition:

	-1	Included in other liabilities is $395,000 and $287,000 accrued for as contingent consideration in connection with the purchase of Lacombe MOB II and a building in the Central Indiana MOB Portfolio, respectively. See Note 14, Fair Value Measurements — Assets and Liabilities Reported at Fair Value — Contingent Consideration, for a further discussion.
	Assuming the property acquisitions in 2013 discussed above had occurred on January 1, 2012, for the three and nine months ended September 30, 2013 and 2012, pro forma revenue, net income (loss), net income (loss) attributable to controlling interest and net income (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,
		2013				2012				2013		2012
	Revenue	$	53,134,000			$	36,958,000			$	150,632,000	$	93,562,000
	Net income (loss)	$	6,297,000			$	(19,262,000	)		$	25,321,000	$	(24,169,000	)
	Net income (loss) attributable to controlling interest	$	6,290,000			$	(19,218,000	)		$	25,281,000	$	(24,104,000	)
	Net income (loss) per common share attributable to controlling interest — basic and diluted	$	0.03			$	(0.19	)		$	0.13	$	(0.28	)
	The pro forma adjustments assume that the debt proceeds and the offering proceeds, at a price of $10.00 per share, net of offering costs were raised as of January 1, 2012. In addition, as acquisition related expenses related to the property acquisitions are not expected to have a continuing impact, they have been excluded from the pro forma results. The pro forma results are not necessarily indicative of the operating results that would have been obtained had the property acquisitions occurred at the beginning of the periods presented, nor are they necessarily indicative of future operating results.
	2012
	For the nine months ended September 30, 2012, we completed 16 property acquisitions comprising 65 buildings. The aggregate purchase price was $654,741,000, plus closing costs and acquisition fees of $20,094,000, which are included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). See Note 3, Real Estate Investments, Net for a listing of the properties acquired, acquisition dates and the amount of financing initially incurred or assumed in connection with such property acquisitions.
	Results of operations for the property acquisitions are reflected in our accompanying condensed consolidated statements of operations and comprehensive income (loss) for the nine months ended September 30, 2012 for the period subsequent to the acquisition date of each property through September 30, 2012. For the period from the acquisition date through September 30, 2012, we recognized the following amounts of revenue and net income for the property acquisitions:
	Acquisition		Revenue				Net Income
	Southeastern SNF Portfolio		$	13,839,000			$	5,158,000
	Other 2012 Acquisitions		$	12,833,000			$	1,276,000
	The following summarizes the fair value of our 2012 property acquisitions at the time of acquisition. We present separately Southeastern SNF Portfolio, which is the one individually significant property acquisition during the nine months ended September 30, 2012, and aggregate the rest of the property acquisitions during the nine months ended September 30, 2012.

	Assuming the property acquisitions in 2012 discussed above had occurred on January 1, 2011, for the three and nine months ended September 30, 2012, pro forma revenue, net (loss) income, 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, 2012				Nine Months Ended September 30, 2012
	Revenue	$	32,691,000			$	96,968,000
	Net (loss) income	$	(10,123,000	)		$	3,985,000
	Net (loss) income attributable to controlling interest	$	(10,125,000	)		$	3,983,000
Net (loss) income per common share attributable to controlling interest — basic and diluted	$	(0.07	)		$	0.03
The pro forma adjustments assume that the debt proceeds and the offering proceeds, at a price of $10.00 per share, net of offering costs were raised as of January 1, 2011. In addition, as acquisition related expenses related to the acquisitions are not expected to have a continuing impact, they have been excluded from the 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	'
	Segment Reporting
	As of September 30, 2013, we evaluated our business and made resource allocations based on four reportable business segments — medical office buildings, hospitals, skilled nursing facilities and senior housing. 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). Our hospital investments are primarily single tenant properties which 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 acquired and similarly structured as our hospital investments.
	We evaluate performance based upon net operating income of the combined properties in each segment. We define net operating income, a non-GAAP financial measure, as total revenues, less rental expenses, which excludes depreciation and amortization, general and administrative expenses, subordinated distribution purchase, acquisition related expenses, interest expense, foreign currency and derivative loss and interest income. 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. Segment net operating income should not be considered as an alternative to net income (loss) determined in accordance with GAAP as an indicator of our financial performance, and, accordingly, we believe that in order to facilitate a clear understanding of our consolidated historical operating results, segment operating income should be examined in conjunction with net income (loss) as presented in our accompanying condensed consolidated financial statements.
	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, receivable from our transfer agent, real estate and escrow deposits, deferred financing costs and other assets not attributable to individual properties.
	Summary information for the reportable segments during the three and nine months ended September 30, 2013 and 2012 was as follows:

Risks and Uncertainties [Abstract]	'
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments that potentially subject us to a concentration of credit risk are primarily real estate notes receivable, cash and cash equivalents, accounts and other receivable, restricted cash and escrow deposits. We are exposed to credit risk with respect to the real estate notes receivable but we believe collection of the outstanding amount is probable and that the risk is further mitigated as the real estate notes receivable are secured by the property and there is a guarantee of completion agreement executed between the parent company of the borrower and us. Cash is generally invested in investment-grade, short-term instruments with a maturity of three months or less when purchased. We have cash in financial institutions that is insured by the Federal Deposit Insurance Corporation, or FDIC. As of September 30, 2013 and December 31, 2012, we had cash and cash equivalents, restricted cash accounts and escrow deposits 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 upon lease execution.
	Based on leases in effect as of September 30, 2013, no one state in the United States accounted for 10.0% or more of our annualized base rent. However, we owned UK Senior Housing Portfolio in the United Kingdom, as of September 30, 2013, which accounted for 17.5% of our annualized base rent. Accordingly, there is a geographic concentration of risk subject to fluctuations in the United Kingdom's economy.
	Based on leases in effect as of September 30, 2013, our four reportable business segments, medical office buildings, skilled nursing facilities, senior housing and hospitals, accounted for 46.3%, 22.7%, 21.5% and 9.5%, respectively, of our annualized base rent. As of September 30, 2013, rental payments by one of our tenants at our properties accounted for 10.0% or more of our annualized base rent, as follows:
	Tenant		2013 Annualized		Percentage of		Property	GLA	Lease Expiration
			Base Rent(1)		Annualized			(Sq Ft)	Date(2)
					Base Rent
	Myriad Healthcare Limited(3)		£	21,610,000	17.5	%	UK Senior Housing Portfolio	962,000	9/10/48
	__________
	-1	Annualized base rent is based on contractual base rent from leases in effect as of September 30, 2013 and was approximately $34,976,000 based on the currency exchange rate as of September 30, 2013. The loss of this tenant or its inability to pay rent could have a material adverse effect on our business and results of operations.
	-2	UK Senior Housing Portfolio is leased to one tenant under a 35-year absolute net lease with lease termination options on October 1, 2028 and October 1, 2038.
	-3	In addition, as of September 30, 2013, we had advanced £6,149,000, or approximately $9,953,000, under real estate notes receivable, to affiliates of Myriad Healthcare Limited. See Note 4, Real Estate Notes Receivable, Net, for a further discussion.

Earnings Per Share [Abstract]	'
Per Share Data	'
	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) allocated to controlling interest by the weighted average number of shares of our common stock outstanding during the period. Net income (loss) allocated to controlling interest is calculated as net income (loss) attributable to controlling interest less distributions allocated to participating securities of$52,000 and $2,000, respectively, for the three months ended September 30, 2013 and 2012, and $99,000 and $7,000, respectively, for the nine months ended September 30, 2013 and 2012. 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 exchangeable 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, 2013 and 2012, there were 25,500 and 13,500 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, 2013 and 2012, there were 281,600 and 200 units, respectively, of exchangeable limited partnership units of our operating partnership outstanding, but such units were also excluded from the computation of diluted earning per share because such units were anti-dilutive during these periods.

Basis of Presentation	'
	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 and any variable interest entities, or VIEs, as defined in Financial Accounting Standards Boards, or FASB, Accounting Standards Codification, or ASC, Topic 810, Consolidation, or ASC Topic 810, which we have concluded should be consolidated pursuant to ASC Topic 810. We operate and intend to continue to operate in an umbrella partnership REIT structure in which our operating partnership, or wholly owned subsidiaries of our operating partnership, will own substantially all of the properties acquired on our behalf. We are the sole general partner of our operating partnership and as of September 30, 2013 and December 31, 2012, we own greater than a 99.90% and 99.96%, respectively, general partnership interest therein. On January 4, 2012, our advisor contributed $2,000 to acquire 200 limited partnership units of our operating partnership and as such, as of September 30, 2013 and December 31, 2012, owns less than a 0.01% noncontrolling limited partnership interest in our operating partnership. Between December 31, 2012 and July 16, 2013, 12 investors contributed their interests in 15 buildings in exchange for 281,600 limited partnership units in our operating partnership. As of September 30, 2013 and December 31, 2012, these investors collectively owned 281,600 and 42,700 limited partnership units, respectively, which represented less than a 0.10% and 0.04%, respectively, noncontrolling limited partnership interest in our operating partnership. Because we are the sole general partner and a limited partner of our operating partnership and have unilateral control over its management and major operating decisions, the accounts of our operating partnership are consolidated in our condensed consolidated financial statements. All significant intercompany accounts and transactions are eliminated in consolidation.
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 2012 Annual Report on Form 10-K, as filed with the SEC on March 15, 2013.
Use of Estimates	'
	Use of Estimates
	The preparation of our condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. 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 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 to meet the contractual obligations under their lease agreements. We maintain an allowance for deferred rent receivables arising from the straight line recognition of rents. Such allowance is charged to bad debt expense which is included in general and administrative in our accompanying condensed consolidated statements of operations and comprehensive income (loss). Our determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, the tenant's financial condition, security deposits, letters of credit, lease guarantees and current economic conditions and other relevant factors.
	As of September 30, 2013 and December 31, 2012, we had $289,000 and $78,000, respectively, in allowance for uncollectible accounts which was determined necessary to reduce receivables to our estimate of the amount recoverable. For the three months ended September 30, 2013 and 2012, we recovered $43,000 and $0, respectively, net, of our receivables that had previously been written off to bad debt expense. For the nine months ended September 30, 2013 and 2012, $48,000 and $0, respectively, net, of our receivables were directly written off to bad debt expense. For the three months ended September 30, 2013 and 2012, none of our receivables, and for the nine months ended September 30, 2013 and 2012, $25,000 and $0, respectively, of our receivables were written off against the allowance for uncollectible accounts. As of September 30, 2013 and December 31, 2012, we did not have an allowance for uncollectible accounts for deferred rent receivables. For the three months ended September 30, 2013 and 2012, $26,000 and $1,000, respectively, and for the nine months ended September 30, 2013 and 2012, $44,000 and $9,000, respectively, of our deferred rent receivables were directly written off to bad debt expense.
Other Liabilities	'
	Other Liabilities
	As of September 30, 2013 and December 31, 2012, included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets was $5,453,000 and $60,204,000, respectively, of contingent consideration obligations in connection with our property acquisitions. Such amounts are due upon certain criteria being met within specified timeframes. For the three months ended September 30, 2013 and 2012, we recorded a net gain (loss) on the change in fair value of contingent consideration of $0 and $(12,446,000), respectively, and for the nine months ended September 30, 2013 and 2012, we recorded a net (loss) on the change in fair value of contingent consideration of $(273,000) and $(12,048,000), respectively, which is included in acquisition related expenses in our accompanying condensed consolidated statements of operations and comprehensive income (loss). See Note 14, Fair Value Measurements — Assets and Liabilities Reported at Fair Value — Contingent Consideration, for a further discussion.
	Also included in security deposits, prepaid rent and other liabilities in our accompanying condensed consolidated balance sheets as of September 30, 2013 is a foreign deferred tax liability of approximately £33,100,000 (or approximately $53,573,000 based on the currency exchange rate as of September 30, 2013) related to the temporary difference between the book basis and the tax basis of our real estate investment assets in the United Kingdom. We measure deferred tax liabilities using enacted tax rates as of the end of each reporting period. The deferred tax liability will be remeasured at each reporting period until it is fully recognized and any change in the liability will be recorded in our accompanying condensed consolidated statements of operations and comprehensive income (loss) in the period of change
Subordinated Distribution Purchase	'
	Subordinated Distribution Purchase
	On September 14, 2012, we and our operating partnership entered into an agreement, or the settlement agreement, with BGC Partners, Inc., or BGC Partners, which held 200 units of limited partnership interest in our operating partnership and would have been entitled to any subordinated distribution that would have been owed to our former advisor and its affiliates, including our former sponsor. Pursuant to the settlement agreement, BGC Partners transferred certain assets to us, including the 200 units of limited partnership interest held in our operating partnership and any rights to the payment of any subordinated distribution for consideration of $4,300,000. Notwithstanding these transfers to us, in the event of a listing event or other liquidity event, as both terms are defined in the partnership agreement for our operating partnership, or the operating partnership agreement, we will calculate a hypothetical deferred termination amount (as defined in the operating partnership agreement and based on assets acquired by us on or before January 10, 2012) for the payment of the subordinated distribution that would have been owed to our former advisor and its affiliates, including our former sponsor. If such calculation results in an amount that is greater than the $4,300,000 paid by us, then we will pay BGC Partners an amount equal to 10.0% of the difference between such calculation and the $4,300,000 paid by us. In connection with the settlement agreement, BGC Partners has agreed to release all known and unknown claims that they may have had against us and our operating partnership.
	Of the $4,300,000 paid by us, $4,232,000 is reflected in our accompanying condensed consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2012 and $68,000 is in satisfaction of all remaining payments owed by us to our former advisor and its affiliates, including our former sponsor, under the G&E Advisory Agreement.
Segment Disclosure	'
	Segment Disclosure
	ASC Topic 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity's reportable segments. As of September 30, 2013, we operated through four reportable business segments — medical office buildings, hospitals, skilled nursing facilities and senior housing. Prior to June 2013, our senior housing segment was referred to as our assisted living facilities segment. Prior to August 2012, we operated through three reportable business segments; however, with the addition of our first senior housing facilities in August 2012, we felt it was useful to segregate our operations into these four reporting segments to assess the performance of our business in the same way that management intends to review our performance and make operating decisions.
	See Note 16, Segment Reporting, for a further discussion.
Foreign Currency Transactions	'
	Foreign Currency
	We have real estate investments in the United Kingdom for which the functional currency is the United Kingdom Pound Sterling, or GBP. We translate the results of operations of our foreign real estate investments into U.S. Dollars, or USD, using the average rates of exchange in effect during the period, and we translate assets and liabilities using the currency exchange rate in effect at the end of the period. The resulting foreign currency translation adjustments are included in accumulated other comprehensive income, or AOCI, a component of stockholders' equity in our accompanying condensed consolidated balance sheets.
	Gains or losses resulting from foreign currency transactions are remeasured into USD at the rates of exchange prevailing on the date of the transactions. The effects of transaction gains/losses are generally included in foreign currency and derivative loss in our condensed consolidated statements of operations and comprehensive income (loss). In addition to the unrealized loss we recorded on our foreign currency forward contract, we recorded $4,971,000 and $4,641,000 for the three and nine months ended September 30, 2013, respectively, in foreign currency transaction gains. See Note 8, Derivative Financial Instruments — Foreign Currency Forward Contract, for a further discussion of our foreign currency forward contract.

	Recently Issued Accounting Pronouncements
	In February 2013, the FASB issued Accounting Standards Update, or ASU, 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, or ASU 2013-02, to improve the transparency of amounts reclassified out of AOCI. The additional disclosure requirements in ASU 2013-02 include: (1) changes in AOCI balances by component and (2) presentation of significant amounts reclassified out of AOCI to net income (loss) by the specific line item of net income (loss)affected. For public entities, ASU 2013-02 is effective prospectively for interim and annual reporting periods beginning after December 15, 2012. We adopted ASU 2013-02 on January 1, 2013, which did not have a material impact on our consolidated financial statements.

Fair Value Unobservable Inputs	'
	The following table shows quantitative information about unobservable inputs related to Level 3 fair value measurements used as of September 30, 2013 for our most significant contingent consideration obligation:
	Property		Fair Value as of September 30, 2013			Unobservable Inputs		Range of Inputs/Inputs
	Pacific Northwest Senior Care Portfolio		$	3,750,000		Achieve Required Lease Coverage Ratios		Yes
						Total Estimated Cost of Tenant Improvements		$6,525,000
						Percentage of Eligible Payment Requested		100%
	Significant increases or decreases in any of the unobservable inputs in isolation or aggregate would result in a significantly higher or lower fair value measurement to each contingent consideration obligation as of September 30, 2013. Lastly, if the counterparty requests something less than 100% of the eligible payment, which they have the right to do so, then the fair value would decrease. If the lease coverage ratio for Pacific Northwest Senior Care Portfolio is not met, then the fair value would decrease to $1,925,000. A decrease in the total cost of the tenant improvements would decrease the fair value of the tenant improvement allowance. An increase in the total cost of the tenants improvements would have no impact on the payment.
	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 ended September 30, 2013 and 2012:
