This liability is remeasured at fair value based on the related redemption price in place as of each balance sheet plus any unpaid distributions. As described previously in Note 8 — Distributions, the Company declared an $0.80 special distribution (or $10.0 million, in total, to the Participation Interest) to all stockholders of the Company in March 2013, which represented a reduction in the Participation Interest liability to reflect a return of capital for the period ending March 31, 2013.

ORGANIZATION	'
	1.  Organization
	The accompanying interim unaudited condensed consolidated financial information has been prepared according to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted according to such rules and regulations. For further information, refer to the financial statements and footnotes for the year ended December 31, 2012 included in Hines Real Estate Investment Trust, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2012. In the opinion of management, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly and in conformity with GAAP the financial position of Hines Real Estate Investment Trust, Inc. as of September 30, 2013 and the results of operations for the three and nine months ended September 30, 2013 and 2012 and cash flows for the nine months ended September 30, 2013 and 2012 have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year.
	Hines Real Estate Investment Trust, Inc., a Maryland corporation (“Hines REIT” and, together with its consolidated subsidiaries, the “Company”), was formed on August 5, 2003 under the Maryland General Corporation Law for the purpose of engaging in the business of investing in and owning interests in real estate. Beginning with its taxable year ended December 31, 2004, the Company operated and intends to continue to operate in a manner to qualify as a real estate investment trust (“REIT”) for federal income tax purposes. The Company is structured as an umbrella partnership REIT under which substantially all of the Company’s current and future business is and will be conducted through its majority-owned subsidiary, Hines REIT Properties, L.P. (the “Operating Partnership”). Hines REIT is the sole general partner of the Operating Partnership. Subject to certain restrictions and limitations, the business of the Company is managed by Hines Advisors Limited Partnership (the “Advisor”), an affiliate of Hines Interests Limited Partnership (“Hines”), pursuant to the advisory agreement between the Company and the Advisor.
	Public Offering
	Hines REIT has raised approximately $2.7 billion through public offerings of its common stock, including shares of its common stock offered pursuant to its dividend reinvestment plan, since Hines REIT commenced its initial public offering in June 2004.  The Company commenced a $150.0 million offering of shares of its common stock under its dividend reinvestment plan on July 1, 2010, which closed on June 30, 2012, immediately prior to the commencement of the Company’s new $300.0 million offering of shares of its common stock under its dividend reinvestment plan on July 1, 2012. The Company refers to both offerings of shares under its dividend reinvestment plan collectively as the “DRP Offering.” From inception of the DRP Offering through September 30, 2013, Hines REIT received gross offering proceeds of $155.1 million from the sale of 18.8 million shares through the DRP Offering. Based on market conditions and other considerations, the Company does not currently expect to commence any future offerings other than those related to shares issued under its dividend reinvestment plan. On October 1, 2013, Hines REIT received gross offering proceeds of $5.9 million from the sale of 0.9 million shares through the DRP Offering.
	Hines REIT contributes all net proceeds from its public offerings to the Operating Partnership in exchange for partnership units in the Operating Partnership. As of September 30, 2013 and December 31, 2012, Hines REIT owned a 94.0% and 94.7% general partner interest, respectively, in the Operating Partnership. Hines 2005 VS I LP, an affiliate of Hines, owned a 0.5% limited partnership interest in the Operating Partnership as of both September 30, 2013 and December 31, 2012. In addition, another affiliate of Hines, HALP Associates Limited Partnership, owned a 5.5% and 4.8% limited partnership interest in the Operating Partnership as of September 30, 2013 and December 31, 2012, respectively, which is a profits interest (the “Participation Interest”).
	Investment Property
	As of September 30, 2013, the Company owned direct and indirect investments in 43 properties. These properties consisted of 30 U.S. office properties, one industrial property in Dallas, Texas and a portfolio of 12 grocery-anchored shopping centers located in five states primarily in the southeastern United States (the “Grocery-Anchored Portfolio”).
	The Company makes investments directly through entities that are wholly-owned by the Operating Partnership, or indirectly through other entities, such as through its investment in Hines US Core Office Fund LP (the “Core Fund”) in which it owned a 27.1% non-managing general partner interest as of both September 30, 2013 and December 31, 2012. The Company also owned a 70% interest in the Grocery-Anchored Portfolio indirectly through a joint venture with Weingarten Realty Investors (“Weingarten”) as of both September 30, 2013 and December 31, 2012. In January 2013, the Company sold its 50% interest in Distribution Park Rio, an industrial property in Rio de Janeiro, Brazil, that was held through a joint venture with a Hines affiliate.  See Note 5 — Investments in Unconsolidated Entities and Note 15 — Subsequent Event for additional information regarding the Company’s investments in unconsolidated entities and the Company’s Grocery-Anchored Portfolio.

Accounting Policies [Abstract]	'
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	'
	2.  Summary of Significant Accounting Policies
	Described below are certain of the Company’s significant accounting policies. The disclosures regarding several of the policies have been condensed or omitted in accordance with interim reporting regulations specified by Form 10-Q. Please see the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a complete listing of all of its significant accounting policies.
	Use of Estimates
	The Company’s condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of the condensed consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company evaluates its assumptions and estimates on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Additionally, application of the Company’s accounting policies involves exercising judgments regarding assumptions as to future uncertainties. Actual results may differ from these estimates under different assumptions or conditions.
	Basis of Presentation
	The condensed consolidated financial statements of the Company included in this quarterly report include the accounts of Hines REIT, the Operating Partnership and the Operating Partnership’s wholly-owned subsidiaries as well as the related amounts of noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation.
	The Company’s investments in partially-owned real estate joint ventures and partnerships are reviewed for impairment periodically. The Company will record an impairment charge if it determines that a decline in the value of an investment below its carrying value is other than temporary.  The Company’s analysis will be dependent on a number of factors, including the performance of each investment, current market conditions, and its intent and ability to hold the investment to full recovery.  Based on the Company’s analysis of the facts and circumstances at each reporting period, no impairment was recorded related to its investments in the Core Fund and the Grocery-Anchored Portfolio for the three and nine months ended September 30, 2013 and 2012. Further, no impairment was recorded related to the Company’s investment in Distribution Park Rio for the three and nine months ended September 30, 2012. The Company sold its investment in Distribution Park Rio in January 2013. See Note 5 — Investments in Unconsolidated Entities for additional information regarding the sale. However, if market conditions deteriorate in the future and result in lower valuations or reduced cash flows of the Company’s remaining investments, impairment charges may be recorded in future periods.
	International Operations
	In addition to its properties in the United States, the Company has owned investments in Canada and Brazil, although the Company no longer owned any investments outside the United States as of September 30, 2013. Upon disposal of the Company’s investment in Distribution Park Rio in January 2013, it realized a loss of $0.9 million related to the currency translation adjustment which was included in the gain (loss) on sale of unconsolidated joint venture in its condensed consolidated statement of operations for the nine months ended September 30, 2013. Accumulated other comprehensive income (loss) as of  September 30, 2013 is related to the remaining non-operating net assets of the disposed directly-owned properties in Brazil and Canada.
	Impairment of Investment Property
	Real estate assets are reviewed for impairment each reporting period if events or changes in circumstances indicate that the carrying amount of the individual property may not be recoverable. In such an event, a comparison will be made of the current and projected cash flows of each property on an undiscounted basis to the carrying amount of such property. If undiscounted cash flows are less than the carrying amount, such carrying amount would be adjusted, if necessary, to estimated fair values to reflect impairment in the value of the asset.  See Note 13 — Fair Value Disclosures for additional information regarding the Company’s policy for determining fair values of its investment property.
	During the third quarter of 2013, the Company determined that its directly-owned investment properties located in Miami, Florida and Minneapolis, Minnesota were impaired, since the projected undiscounted cash flows for these properties were less than their carrying values. Additionally, during the second quarter of 2013, the Company determined that its directly-owned investment property located in Minneapolis, Minnesota was impaired as a result of the projected undiscounted cash flows for the property being less than its carrying values. As a result, an impairment loss was recorded related to those certain properties of $30.6 million and $32.2 million for the three and nine months ended September 30, 2013, respectively. See Note 4 — Discontinued Operations for information regarding impairment recorded on the Company’s disposed properties.
	During the second quarter of 2012, the Company determined that two of its directly-owned investment properties located in Melville, New York and Seattle, Washington were impaired, since the projected undiscounted cash flows for these properties were less than their carrying values. As a result, an impairment loss related to those certain properties of $46.1 million was recorded for the nine months ended September 30, 2012. If market conditions deteriorate or if management’s plans for certain properties change, additional impairment changes could be required in the future. See Note 13 — Fair Value Disclosures for additional information.
	During 2012, an impairment loss totaling $12.5 million was recorded related to five of the Company’s indirectly-owned properties located in a suburban area of Sacramento, California for the nine months ended September 30, 2012. Of these five indirectly-owned properties, four of those were subsequently sold during the fourth quarter of 2012. See Note 5 — Investments in Unconsolidated Entities for additional information.
	Tenant and Other Receivables
	Receivable balances outstanding consist primarily of base rents, tenant reimbursements and receivables attributable to straight-line rent.  An allowance for the uncollectible portion of tenant and other receivables is determined based upon an analysis of the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. Tenant and other receivables are shown at cost in the condensed consolidated balance sheets, net of allowance for doubtful accounts of $5.0 million and $6.1 million at September 30, 2013 and December 31, 2012, respectively.
	Deferred Leasing Costs
	Tenant inducement amortization was $4.2 million and $4.1 million for the three months ended September 30, 2013 and 2012, respectively, and was recorded as an offset to rental revenue. In addition, the Company recorded $1.5 million and $1.7 million as amortization expense related to other direct leasing costs for the three months ended September 30, 2013 and 2012, respectively.
	Tenant inducement amortization was $12.8 million and $11.3 million for the nine months ended September 30, 2013 and 2012, respectively, and was recorded as an offset to rental revenue. In addition, the Company recorded $4.8 million as amortization expense related to other direct leasing costs for each of the nine months ended September 30, 2013 and 2012, respectively.
	Other Assets
	Other assets included the following (in thousands):
		September 30, 2013		December 31, 2012
	Prepaid insurance	$	1,384	$	972

	Other	1,049		880

	Rental payments are generally paid by the tenants prior to the beginning of each month. As of September 30, 2013 and December 31, 2012, the Company recorded liabilities of $6.2 million and $11.1 million, respectively, related to prepaid rental payments which were included in other liabilities in the accompanying condensed consolidated balance sheets. The Company recognizes rental revenue on a straight-line basis over the life of the lease including rent holidays, if any. Straight-line rent receivable was $40.4 million and $56.2 million as of September 30, 2013 and December 31, 2012, respectively.
	Redemption of Common Stock
	In March 2013, the Company’s board of directors amended and restated the Company’s share redemption program to reinstate the program effective for share redemption requests received on or after April 1, 2013 at $5.75 per share, subject to the conditions and limitations described in the amended and restated share redemption program. Prior to its reinstatement, the share redemption program had been suspended by the board of directors since November 30, 2009, except with respect to redemption requests made in connection with the death or disability (as defined in the Internal Revenue Code of 1986, as amended) of a stockholder. Generally, funds available for redemption are limited to the amount of proceeds received from the Company’s dividend reinvestment plan in the prior quarter.  However, the Board has the discretion to redeem shares in excess of this amount if it determines there are sufficient available funds and it is appropriate to do so as long as the total amount redeemed does not exceed the amount required to redeem 10% of the Company’s shares outstanding as of the same date in the prior calendar year. The Board determined to waive the limitation on the share redemption plan and fully honor all eligible requests received for the quarters ended June 30, 2013 and September 30, 2013 totaling $38.0 million, which was in excess of the $17.1 million received from the dividend reinvestment plan in the prior quarters. The Company has recorded liabilities of $11.5 million and $2.6 million in accounts payable and accrued expenses in the accompanying condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012, respectively, related to shares tendered for redemption and approved by the board of directors, but which were not redeemed until the subsequent month. Such amounts have been included in redemption of common shares in the accompanying condensed consolidated statements of equity.
	Reclassifications
	The Company sold Williams Tower, One Wilshire and the Raytheon/DIRECTV buildings during 2013 and reclassified the results of operations for these properties into discontinued operations in the consolidated statements of operations for all periods presented. See Note 4 — Discontinued Operations for additional information.
	Recent Accounting Pronouncements
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued guidance on disclosures about offsetting assets and liabilities. This guidance results in enhanced disclosures by requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either ASC 210-20-45 or ASC 815-10-45. The adoption of this guidance was effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. The adoption of this guidance did not have a material effect on the Company’s financial statements.
	In October 2012, FASB clarified and relocated guidance in the Accounting Standards Codification (the “Codification”), corrected unintended application of guidance and made minor improvements to the Codification that are not expected to have a significant effect on current accounting practice. Amendments made to the Codification without transition guidance were effective upon issuance and amendments subject to transition guidance was effective for fiscal periods beginning after December 15, 2012. This guidance did not have a material impact on the Company’s financial statements.
	In February 2013, FASB issued guidance to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The adoption of this guidance was effective for interim and annual periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.
	In February 2013, FASB issued amendments to provide guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP.  The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.
	In March 2013, FASB issued guidance on releasing cumulative translation adjustments when a reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustments in partial sales of equity method investments.  The guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years beginning after December 15, 2013. The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.
	In July 2013, FASB issued amendments to the Codification to provide guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.  These amendments will be effective for fiscal years, and interim periods within those years, beginning after December 31, 2013. The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.

	The following discusses items of significance for the periods presented for the Company’s equity method investments:
	In June 2013, the Core Fund sold 425 Lexington Avenue, 499 Park Avenue and 1200 19th Street (collectively, the “New York Trust Assets”). Both 425 Lexington and 499 Park Avenue are located in midtown Manhattan, New York and 1200 19th Street is located in the Golden Triangle in Washington D.C.’s central business district. The Core Fund acquired the New York Trust Assets in August 2003 for a contract purchase price $581.1 million. The contract sales price was $1,311.0 million. As a result of the sale of the New York Trust Assets, the Core Fund recognized a gain on sale of $291.6 million. The results of operations for the NY Trust Assets were reclassified into discontinued operations for the periods presented in the table above as a result of this transaction. The Core Fund paid a distribution to the Company in the amount of $81.3 million in August 2013, a majority of which was related to the sale of the New York Trust Assets.
	During the nine months ended September 30, 2012, the Core Fund recorded an impairment loss of $12.5 million related to four of its properties located in suburban Sacramento, California, which have been reclassified into discontinued operations in the table above as a result of the subsequent sale of these four properties in the fourth quarter of 2012. Due to deterioration in the financial condition at Douglas Corporate Center, the Core Fund elected to not make debt service payments on the secured, nonrecourse mortgage loan at the property.  This decision resulted in a default and a foreclosure on the property by the lender in January 2013.  As a result of the foreclosure, the Core Fund relinquished all rights and title to the property and was relieved of the entire value of the mortgage loan and recognized a gain of $12.6 million for the nine months ended September 30, 2013. The results of operations for this property were reclassified into discontinued operations for the periods presented in the table above as a result of this transaction.
	During the nine months ended September 30, 2012, a subsidiary of the Core Fund executed discounted pay-off agreements with lenders concerning the debt secured by One Renaissance Square and Two Renaissance Square, office buildings located in Phoenix, Arizona, to release the Core Fund from all outstanding debt and obligations, including the outstanding principal balances of $103.6 million, at a discounted amount of $89.3 million.  As a result of the debt extinguishment, the Core Fund recognized a gain on debt extinguishment of $12.6 million, net of service costs and fees.
	Grocery-Anchored Portfolio
	At September 30, 2013 and December 31, 2012, the Company’s investment in the Grocery-Anchored Portfolio was determined to be a variable interest entity (“VIE”) due to certain payment guarantees that result in the protection of the Company’s equity from expected losses. Further, the JV partner has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and, as a result, the Company has determined it is not the primary beneficiary of this VIE. The Company’s maximum loss exposure is expected to change in future periods as a result of income earned, distributions received and contributions made. In April 2013, the Company contributed $10.2 million to the joint venture in order for the joint venture to retire a loan at one of its properties without a prepayment penalty. In September 2013, the Company contributed $23.7 million to relieve a preferred equity position held by a third-party in the joint venture. Also, in October 2013, the Company contributed $70.2 million to the joint venture in order for the joint venture to retire its $100.0 million secured loan without a prepayment penalty. Other than the initial capital contribution provided by the Company at the inception of the joint venture and the contributions mentioned above, the Company has not provided any additional subordinated financial support. See Note 15 — Subsequent Event for additional information regarding the Company’s Grocery-Anchored Portfolio.
	The table below includes the Company’s maximum loss exposure related to this investment as of September 30, 2013 and December 31, 2012, which is equal to the carrying value of its investment in the joint venture included in the balance sheet line item “Investments in unconsolidated entities” for each period. Amounts are in thousands:

DISTRIBUTIONS	'
	8.  Distributions
	With the authorization of its board of directors, the Company declared distributions in the amount of $0.00138082 per share, per day from July 1, 2010 through March 31, 2013, which represented an annual distribution rate of 6.5%, based on the Company’s estimated per share net asset value (“NAV”) of $7.78, determined on May 24, 2011 or 6.6%, based on the Company’s estimated per share NAV of $7.61, determined on November 29, 2012 (assuming the distribution rates were maintained for a twelve-month period).
	With respect to the $0.00138082 per share, per day distributions declared for the periods from January 1, 2012 through March 31, 2013, presented below, $0.00041425 of the per share, per day distributions were designated by the Company as special distributions which represent a return of a portion of the stockholders’ invested capital and, as such, reduce their remaining investment in the Company. The special distributions were funded with a portion of the proceeds from sales of investment property.
	On March 25, 2013, the Company declared a distribution of approximately $198.0 million, resulting in a distribution to stockholders of $0.80 per share that was paid during the three months ended June 30, 2013 to all stockholders of record as of April 2, 2013, which is reflected in the table below. This distribution was designated by the Company as a special distribution, which was a return of a portion of the stockholders’ invested capital and, as such, reduced their remaining investment in the Company. The special distribution represents a portion of the proceeds from the sale of Williams Tower and other strategic asset sales. The special distribution was not subject to reinvestment pursuant to the Company’s dividend reinvestment plan and was paid in cash.
	As disclosed above, approximately 30% of distributions that were declared for the quarters ended December 31, 2012 and March 31, 2013 were designated by the Company as special distributions, which represent a return of a portion of the stockholders’ invested capital and, as such, reduced their remaining investment in the Company. For each of the quarters ended December 31, 2012 and March 31, 2013, the portion of the distribution that was designated as a special distribution was equal to $0.03 per share. The combination of the special distribution of $0.80 per share described above with the $0.03 per share special distributions for each of the quarters ended December 31, 2012 and March 31, 2013 results in total special distributions of $0.86 per share since the Company’s last announcement of its estimated per share NAV of its common stock. These special distributions reduced the estimated per share NAV of $7.61, resulting in a new estimated per share NAV of $6.75, effective April 2, 2013.
	Further, with the authorization of its board of directors, the Company declared distributions for April 2013 through November 2013. These distributions will be calculated based on stockholders of record each day during this period in an amount equal to $0.00073973 per share, per day and will be paid on the first day of the month following the fiscal quarter to which they relate in cash, or reinvested in stock for those participating in the Company's dividend reinvestment plan. This rate per share, per day, reflects a reduction from the $0.00138082 per share, per day rate that was declared previously, as described above. This rate per share, per day represents a 4.0% annual distribution rate based on the Company's most recent estimated per share NAV of $6.75, assuming such distribution rate is maintained for a twelve-month period.
	The table below outlines the Company’s total distributions declared to stockholders and noncontrolling interests for each of the quarters during 2013 and 2012, including the breakout between the distributions paid in cash and those reinvested pursuant to the Company’s dividend reinvestment plan (all amounts are in thousands).

The amount of distributions declared with respect to the Participation Interest for the quarters ended September 30, 2013, June 30, 2013 and March 31, 2013 were $0.9 million, $0.9 million and $1.5 million, respectively. Included in the $226.1 million amount declared at March 31, 2013 above is the $10.0 million special distribution declared in March 2013 to the Participation Interest. The distributions declared with respect to the Participation Interest for the quarters ended December 31, 2012, September 30, 2012, June 30, 2012 and March 31, 2012 were $1.5 million, $1.4 million, $1.3 million and $1.3 million, respectively.
	-2	As stated above, a portion of the total distributions declared were designated by the Company as special distributions and funded using proceeds from sales of investment property, which represents a return of a portion of the stockholders and noncontrolling interests’ invested capital. For the nine months ended September 30, 2013, $206.7 million of the Company’s distributions declared were designated as special distributions, $198.0 million of which related to the one-time $0.80 per share special distribution described above. For the year ended December 31, 2012, $35.0 million of the total distributions declared to the Company’s stockholders and non-controlling interests were paid using such sales proceeds.

	12.  Commitments and Contingencies
	The credit agreement for the HSH Nordbank pooled mortgage facility requires that the properties financed by this facility maintain a combined occupancy at or above 85%. As of September 30, 2013, certain properties caused the Company to fail to meet this occupancy requirement. As a result, the facility’s limited payment guaranty to which the Company is a party has been triggered, requiring the Company to commit to fund a property leasing guaranty in an amount that would be required to increase the occupancy of all individual borrowings base assets to 90%. As of September 30, 2013, the Company believes the amount of this potential guaranty obligation is $17.5 million. This guaranty will be discharged once the portfolio of properties financed by this facility achieves a combined occupancy greater than or equal to 85% or once all outstanding payments of interest and principal are paid in full. No liability was recorded in relation to this guaranty, as the Company believes the probability of the Company being required to perform under this guaranty is remote.
	The Company is subject to various legal proceedings and claims that arise in the ordinary course of business. These matters are generally covered by insurance. While the resolution of these matters cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on the Company’s condensed consolidated financial statements.

Fair Value Disclosures [Abstract]	'
FAIR VALUE DISCLOSURES	'
	13.  Fair Value Disclosures
	Assets and Liabilities Measured at Fair Value on a Recurring Basis
	Derivative Instruments
	The Company records liabilities related to the fair values of its interest rate swap contracts. The valuation of these instruments is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques including 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 and implied volatilities.  The fair values of the Company’s interest rate contracts have been determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.
	Although the Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparty, HSH Nordbank. In adjusting the fair values of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuations of its derivatives. As a result, the Company has determined its derivative valuations are classified in Level 2 of the fair value hierarchy.
	The following fair value hierarchy table sets forth the Company’s interest rate swaps which are measured at fair value on a recurring basis, which equals book value, by level within the fair value hierarchy as of September 30, 2013 and December 31, 2012 (in thousands).  The Company’s derivative financial instruments are recorded in interest rate swap contracts in the accompanying condensed consolidated balance sheets.  The Company has not designated any of its derivative instruments as hedging instruments for accounting purposes.
					Basis of Fair Value Measurements

	December 31, 2012		$	101,211	$	—	$	101,211	$	—
	Financial Instruments Fair Value Disclosures
	Other Financial Instruments
	As of September 30, 2013, management estimated that the fair value of notes payable, which had a carrying value of $797.1 million, was $791.1 million. As of December 31, 2012, management estimated that the fair value of notes payable, which had a carrying value of $1.3 billion, was $1.3 billion. The discount rates used approximate current lending rates for loans or groups of loans with similar maturities and credit quality, assumes the debt is outstanding through maturity and considers the debt’s collateral (if applicable).  Management has utilized market information as available or present value techniques to estimate the amounts required to be disclosed. The Company has determined the majority of the inputs used to value its notes payable fall within Level 2 of the fair value hierarchy, however the credit quality adjustments associated with its fair value of notes payable utilize Level 3 inputs. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit quality adjustments on the overall valuations of its fair market value of notes payable and has determined that they are not significant.  As a result, the Company has determined these financial instruments utilize Level 2 inputs. Since such amounts are estimates that are based on limited available market information for similar transactions, there can be no assurance that the disclosed values could be realized.
	Other financial instruments not measured at fair value on a recurring basis include cash and cash equivalents, restricted cash, distributions receivable, tenant and other receivables, accounts payable and accrued expenses, other liabilities, due to affiliates and distributions payable.  The carrying value of these items reasonably approximates their fair value based on their highly-liquid nature and/or short-term maturities.  Due to the short-term nature of these instruments, Level 1 and Level 2 inputs are utilized to estimate the fair value of these financial instruments.
	Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis
	Certain long-lived assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments (i.e., impairments) in certain circumstances. The fair value methodologies used to measure long-lived assets are described in Note 2 — Summary of Significant Accounting Policies — Impairment of Investment Property. The inputs associated with the valuation of long-lived assets are generally included in Level 2 or Level 3 of the fair value hierarchy, as discussed below.
	Impairment of Investment Property
	Investment properties are reviewed for impairment at each reporting period if events or changes in circumstances indicate that the carrying amount may not be recoverable. At September 30, 2013, the Company determined that its directly-owned investments, Airport Corporate Center and Minneapolis Office/Flex portfolio, were impaired due to a shortened expected hold period, which reduced the projected undiscounted cash flows for these investments. Also, Minneapolis Office/Flex portfolio was impaired during the quarter ended September 30, 2013 due to a reduction in market conditions.
	Additionally, at December 31, 2012, the Company determined that its directly-owned investments, Seattle Design Center and Three Huntington Quadrangle, were impaired due to a shortened expected hold period, which reduced the projected undiscounted cash flows for these investments. Lastly, at December 31, 2012, the Company determined that its directly-owned investment, a building in its Minneapolis Office/Flex portfolio, was impaired due to a change in leasing assumptions and appraised value.
	These changes in assumptions resulted in the net book value of the assets exceeding the projected undiscounted cash flows for these investments. As a result, these assets were written down to fair value. The following table summarizes activity for the Company’s assets measured at fair value, on a non-recurring basis, as of September 30, 2013 and December 31, 2012:
			Basis of Fair Value Measurements

	-2	Of this amount, zero and $46.1 million in impairment losses were recorded for the three and nine months ended September 30, 2012.
	The Company’s estimated fair value of investment properties was based on a comparison of recent market activity and discounted cash flow models, which include estimates of property-specific inflows and outflows over a specific holding period.  Significant unobservable quantitative inputs used in determining the fair value of each investment property for the period ended September 30, 2013 include: a discount rate ranging from 5% to 9%; a capitalization rate ranging from 7.5% to 9.5%; stabilized occupancy rates ranging from 82% through 95%; and current market rental rates ranging from $4.25 per square foot to $12.50 per square foot.  These inputs are based on the location, type and nature of each property, current and anticipated market conditions, and management’s knowledge and expertise in real estate.
	The Company’s estimated fair value of the investment properties in Minneapolis, Minnesota, Melville, New York and Seattle, Washington as of December 31, 2012 was based on a comparison of recent market activity and discounted cash flow models, which include estimates of property specific inflows and outflows over a specific holding period.  Significant unobservable quantitative inputs used in determining the fair value of each investment include: discount rates ranging from 8% through 13%; a capitalization rate of 8.5%; stabilized occupancy rates ranging from 82% through 93%; and current market rental rates ranging from $11.20 per square foot to $21.50 per square foot.  These inputs are based on the location, type and nature of each property, current and anticipated market conditions, and management’s knowledge and expertise in real estate.

REPORTABLE SEGMENTS	'
	14.  Reportable Segments
	The Company’s investments in real estate are geographically diversified and management evaluates the operating performance of each at an individual property level. The Company has determined it has three reportable segments: (1) office properties, (2) a domestic industrial property and (3) domestic retail properties. The office properties segment consists of 17 office properties that the Company owns directly as well as 13 office properties that are owned indirectly through the Company’s investment in the Core Fund. The domestic industrial property segment consists of one directly-owned industrial property located in Dallas, Texas. The domestic retail segment consists of the 12 grocery-anchored shopping centers in the Grocery-Anchored Portfolio. In 2012, the Company considered its investment in Distribution Park Rio as a separate international industrial property segment, however, in January 2013, the Company sold its indirect investment in Distribution Park Rio.
	The Company’s indirect investments are accounted for using the equity method of accounting. As such, the activities of these investments are reflected in investments in unconsolidated entities in the condensed consolidated balance sheets and equity in earnings (losses) of unconsolidated entities, net in the condensed consolidated statements of operations. As discussed above, in January 2013, the Company sold its indirect investment in Distribution Park Rio, which is reflected in the tables below.
	The tables below provide additional information related to each of the Company’s segments (in thousands) and a reconciliation to the Company’s net income or loss, as applicable. “Corporate-Level Accounts” includes amounts incurred by the corporate-level entities which are not allocated to any of the reportable segments.

Accounting Policies [Abstract]

'

Use Of Estimates Policy [Policy Text Block]

'

Use of Estimates

The Company’s condensed consolidated financial statements have been prepared in accordance with GAAP. The preparation of the condensed consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company evaluates its assumptions and estimates on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Additionally, application of the Company’s accounting policies involves exercising judgments regarding assumptions as to future uncertainties. Actual results may differ from these estimates under different assumptions or conditions.

Basis Of Accounting Policy [Policy Text Block]

'

Basis of Presentation

The condensed consolidated financial statements of the Company included in this quarterly report include the accounts of Hines REIT, the Operating Partnership and the Operating Partnership’s wholly-owned subsidiaries as well as the related amounts of noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation.

Equity Method Investments Policy [Policy Text Block]

'

The Company makes investments directly through entities that are wholly-owned by the Operating Partnership, or indirectly through other entities, such as through its investment in Hines US Core Office Fund LP (the “Core Fund”) in which it owned a 27.1% non-managing general partner interest as of both September 30, 2013 and December 31, 2012. The Company also owned a 70% interest in the Grocery-Anchored Portfolio indirectly through a joint venture with Weingarten Realty Investors (“Weingarten”) as of both September 30, 2013 and December 31, 2012. In January 2013, the Company sold its 50% interest in Distribution Park Rio, an industrial property in Rio de Janeiro, Brazil, that was held through a joint venture with a Hines affiliate.  See Note 5 — Investments in Unconsolidated Entities and Note 15 — Subsequent Event for additional information regarding the Company’s investments in unconsolidated entities and the Company’s Grocery-Anchored Portfolio.

The Company’s investments in partially-owned real estate joint ventures and partnerships are reviewed for impairment periodically. The Company will record an impairment charge if it determines that a decline in the value of an investment below its carrying value is other than temporary.  The Company’s analysis will be dependent on a number of factors, including the performance of each investment, current market conditions, and its intent and ability to hold the investment to full recovery.  Based on the Company’s analysis of the facts and circumstances at each reporting period, no impairment was recorded related to its investments in the Core Fund and the Grocery-Anchored Portfolio for the three and nine months ended September 30, 2013 and 2012. Further, no impairment was recorded related to the Company’s investment in Distribution Park Rio for the three and nine months ended September 30, 2012. The Company sold its investment in Distribution Park Rio in January 2013. See Note 5 — Investments in Unconsolidated Entities for additional information regarding the sale. However, if market conditions deteriorate in the future and result in lower valuations or reduced cash flows of the Company’s remaining investments, impairment charges may be recorded in future periods.

Foreign Currency Transactions And Translations Policy[Policy Text Block]

'

International Operations

In addition to its properties in the United States, the Company has owned investments in Canada and Brazil, although the Company no longer owned any investments outside the United States as of September 30, 2013. Upon disposal of the Company’s investment in Distribution Park Rio in January 2013, it realized a loss of $0.9 million related to the currency translation adjustment which was included in the gain (loss) on sale of unconsolidated joint venture in its condensed consolidated statement of operations for the nine months ended September 30, 2013. Accumulated other comprehensive income (loss) as of  September 30, 2013 is related to the remaining non-operating net assets of the disposed directly-owned properties in Brazil and Canada.

Impairment Or Disposal Of Long Lived Assets Policy [Policy Text Block]

'

Impairment of Investment Property

Real estate assets are reviewed for impairment each reporting period if events or changes in circumstances indicate that the carrying amount of the individual property may not be recoverable. In such an event, a comparison will be made of the current and projected cash flows of each property on an undiscounted basis to the carrying amount of such property. If undiscounted cash flows are less than the carrying amount, such carrying amount would be adjusted, if necessary, to estimated fair values to reflect impairment in the value of the asset.  See Note 13 — Fair Value Disclosures for additional information regarding the Company’s policy for determining fair values of its investment property.

During the third quarter of 2013, the Company determined that its directly-owned investment properties located in Miami, Florida and Minneapolis, Minnesota were impaired, since the projected undiscounted cash flows for these properties were less than their carrying values. Additionally, during the second quarter of 2013, the Company determined that its directly-owned investment property located in Minneapolis, Minnesota was impaired as a result of the projected undiscounted cash flows for the property being less than its carrying values. As a result, an impairment loss was recorded related to those certain properties of $30.6 million and $32.2 million for the three and nine months ended September 30, 2013, respectively. See Note 4 — Discontinued Operations for information regarding impairment recorded on the Company’s disposed properties.

During the second quarter of 2012, the Company determined that two of its directly-owned investment properties located in Melville, New York and Seattle, Washington were impaired, since the projected undiscounted cash flows for these properties were less than their carrying values. As a result, an impairment loss related to those certain properties of $46.1 million was recorded for the nine months ended September 30, 2012. If market conditions deteriorate or if management’s plans for certain properties change, additional impairment changes could be required in the future. See Note 13 — Fair Value Disclosures for additional information.

During 2012, an impairment loss totaling $12.5 million was recorded related to five of the Company’s indirectly-owned properties located in a suburban area of Sacramento, California for the nine months ended September 30, 2012. Of these five indirectly-owned properties, four of those were subsequently sold during the fourth quarter of 2012. See Note 5 — Investments in Unconsolidated Entities for additional information.

Tenant and Other Receivables Policy [Policy Text Block]

'

Tenant and Other Receivables

Receivable balances outstanding consist primarily of base rents, tenant reimbursements and receivables attributable to straight-line rent.  An allowance for the uncollectible portion of tenant and other receivables is determined based upon an analysis of the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. Tenant and other receivables are shown at cost in the condensed consolidated balance sheets, net of allowance for doubtful accounts of $5.0 million and $6.1 million at September 30, 2013 and December 31, 2012, respectively.

Deferred Charges Policy [Policy Text Block]

'

Deferred Leasing Costs

Tenant inducement amortization was $4.2 million and $4.1 million for the three months ended September 30, 2013 and 2012, respectively, and was recorded as an offset to rental revenue. In addition, the Company recorded $1.5 million and $1.7 million as amortization expense related to other direct leasing costs for the three months ended September 30, 2013 and 2012, respectively.

Tenant inducement amortization was $12.8 million and $11.3 million for the nine months ended September 30, 2013 and 2012, respectively, and was recorded as an offset to rental revenue. In addition, the Company recorded $4.8 million as amortization expense related to other direct leasing costs for each of the nine months ended September 30, 2013 and 2012, respectively.

Rental payments are generally paid by the tenants prior to the beginning of each month. As of September 30, 2013 and December 31, 2012, the Company recorded liabilities of $6.2 million and $11.1 million, respectively, related to prepaid rental payments which were included in other liabilities in the accompanying condensed consolidated balance sheets. The Company recognizes rental revenue on a straight-line basis over the life of the lease including rent holidays, if any. Straight-line rent receivable was $40.4 million and $56.2 million as of September 30, 2013 and December 31, 2012, respectively.

Common Stock Redemption Policy [Policy Text Block]

'

Redemption of Common Stock

In March 2013, the Company’s board of directors amended and restated the Company’s share redemption program to reinstate the program effective for share redemption requests received on or after April 1, 2013 at $5.75 per share, subject to the conditions and limitations described in the amended and restated share redemption program. Prior to its reinstatement, the share redemption program had been suspended by the board of directors since November 30, 2009, except with respect to redemption requests made in connection with the death or disability (as defined in the Internal Revenue Code of 1986, as amended) of a stockholder. Generally, funds available for redemption are limited to the amount of proceeds received from the Company’s dividend reinvestment plan in the prior quarter.  However, the Board has the discretion to redeem shares in excess of this amount if it determines there are sufficient available funds and it is appropriate to do so as long as the total amount redeemed does not exceed the amount required to redeem 10% of the Company’s shares outstanding as of the same date in the prior calendar year. The Board determined to waive the limitation on the share redemption plan and fully honor all eligible requests received for the quarters ended June 30, 2013 and September 30, 2013 totaling $38.0 million, which was in excess of the $17.1 million received from the dividend reinvestment plan in the prior quarters. The Company has recorded liabilities of $11.5 million and $2.6 million in accounts payable and accrued expenses in the accompanying condensed consolidated balance sheets as of September 30, 2013 and December 31, 2012, respectively, related to shares tendered for redemption and approved by the board of directors, but which were not redeemed until the subsequent month. Such amounts have been included in redemption of common shares in the accompanying condensed consolidated statements of equity.

New Accounting Pronouncements Policy [Policy Text Block]

'

Recent Accounting Pronouncements

In December 2011, the Financial Accounting Standards Board (“FASB”) issued guidance on disclosures about offsetting assets and liabilities. This guidance results in enhanced disclosures by requiring improved information about financial instruments and derivative instruments that are either (1) offset in accordance with either ASC 210-20-45 or ASC 815-10-45 or (2) subject to an enforceable master netting arrangement or similar agreement, irrespective of whether they are offset in accordance with either ASC 210-20-45 or ASC 815-10-45. The adoption of this guidance was effective for annual periods beginning on or after January 1, 2013 and interim periods within those annual periods. The adoption of this guidance did not have a material effect on the Company’s financial statements.

In October 2012, FASB clarified and relocated guidance in the Accounting Standards Codification (the “Codification”), corrected unintended application of guidance and made minor improvements to the Codification that are not expected to have a significant effect on current accounting practice. Amendments made to the Codification without transition guidance were effective upon issuance and amendments subject to transition guidance was effective for fiscal periods beginning after December 15, 2012. This guidance did not have a material impact on the Company’s financial statements.

In February 2013, FASB issued guidance to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. The adoption of this guidance was effective for interim and annual periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s financial statements.

In February 2013, FASB issued amendments to provide guidance on the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of obligation within the scope of this guidance is fixed at the reporting date, except for obligations addressed within existing guidance in GAAP.  The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013.  The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.

In March 2013, FASB issued guidance on releasing cumulative translation adjustments when a reporting entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity.  In addition, these amendments provide guidance on the release of cumulative translation adjustments in partial sales of equity method investments.  The guidance is effective on a prospective basis for fiscal years and interim reporting periods within those years beginning after December 15, 2013. The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.

In July 2013, FASB issued amendments to the Codification to provide guidance on the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.  These amendments will be effective for fiscal years, and interim periods within those years, beginning after December 31, 2013. The Company does not believe the adoption of this guidance will have a material impact on the Company’s financial statements.

Derivatives Methods Of Accounting Nonhedging Derivatives Policy [Policy Text Block]

'

The Company has entered into several interest rate swap transactions with HSH Nordbank. These swap transactions were entered into as economic hedges against the variability of future interest rates on the Company’s variable interest rate borrowings with HSH Nordbank. The Company has not designated any of its derivative instruments as hedging instruments for accounting purposes. The interest rate swaps have been recorded at their estimated fair value in the accompanying condensed consolidated balance sheets and changes in the fair value were recorded in gain (loss) on derivative instruments, net in the Company’s condensed consolidated statements of operations (see Note 13 ─ Fair Value Disclosures for additional information).

Fair Value Of Financial Instruments Policy [Policy Text Block]

'

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Derivative Instruments

The Company records liabilities related to the fair values of its interest rate swap contracts. The valuation of these instruments is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques including 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 and implied volatilities.  The fair values of the Company’s interest rate contracts have been determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts).  The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

Although the Company has determined the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparty, HSH Nordbank. In adjusting the fair values of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuations of its derivatives. As a result, the Company has determined its derivative valuations are classified in Level 2 of the fair value hierarchy.

The following fair value hierarchy table sets forth the Company’s interest rate swaps which are measured at fair value on a recurring basis, which equals book value, by level within the fair value hierarchy as of September 30, 2013 and December 31, 2012 (in thousands).  The Company’s derivative financial instruments are recorded in interest rate swap contracts in the accompanying condensed consolidated balance sheets.  The Company has not designated any of its derivative instruments as hedging instruments for accounting purposes.

Financial Instruments Fair Value Disclosures

Other Financial Instruments

As of September 30, 2013, management estimated that the fair value of notes payable, which had a carrying value of $797.1 million, was $791.1 million. As of December 31, 2012, management estimated that the fair value of notes payable, which had a carrying value of $1.3 billion, was $1.3 billion. The discount rates used approximate current lending rates for loans or groups of loans with similar maturities and credit quality, assumes the debt is outstanding through maturity and considers the debt’s collateral (if applicable).  Management has utilized market information as available or present value techniques to estimate the amounts required to be disclosed. The Company has determined the majority of the inputs used to value its notes payable fall within Level 2 of the fair value hierarchy, however the credit quality adjustments associated with its fair value of notes payable utilize Level 3 inputs. However, as of September 30, 2013, the Company has assessed the significance of the impact of the credit quality adjustments on the overall valuations of its fair market value of notes payable and has determined that they are not significant.  As a result, the Company has determined these financial instruments utilize Level 2 inputs. Since such amounts are estimates that are based on limited available market information for similar transactions, there can be no assurance that the disclosed values could be realized.

Other financial instruments not measured at fair value on a recurring basis include cash and cash equivalents, restricted cash, distributions receivable, tenant and other receivables, accounts payable and accrued expenses, other liabilities, due to affiliates and distributions payable.  The carrying value of these items reasonably approximates their fair value based on their highly-liquid nature and/or short-term maturities.  Due to the short-term nature of these instruments, Level 1 and Level 2 inputs are utilized to estimate the fair value of these financial instruments.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain long-lived assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments (i.e., impairments) in certain circumstances. The fair value methodologies used to measure long-lived assets are described in Note 2 — Summary of Significant Accounting Policies — Impairment of Investment Property. The inputs associated with the valuation of long-lived assets are generally included in Level 2 or Level 3 of the fair value hierarchy, as discussed below.

Impairment of Investment Property

Investment properties are reviewed for impairment at each reporting period if events or changes in circumstances indicate that the carrying amount may not be recoverable. At September 30, 2013, the Company determined that its directly-owned investments, Airport Corporate Center and Minneapolis Office/Flex portfolio, were impaired due to a shortened expected hold period, which reduced the projected undiscounted cash flows for these investments. Also, Minneapolis Office/Flex portfolio was impaired during the quarter ended September 30, 2013 due to a reduction in market conditions.

Additionally, at December 31, 2012, the Company determined that its directly-owned investments, Seattle Design Center and Three Huntington Quadrangle, were impaired due to a shortened expected hold period, which reduced the projected undiscounted cash flows for these investments. Lastly, at December 31, 2012, the Company determined that its directly-owned investment, a building in its Minneapolis Office/Flex portfolio, was impaired due to a change in leasing assumptions and appraised value.

These changes in assumptions resulted in the net book value of the assets exceeding the projected undiscounted cash flows for these investments. As a result, these assets were written down to fair value. The following table summarizes activity for the Company’s assets measured at fair value, on a non-recurring basis, as of September 30, 2013 and December 31, 2012:

Of this amount, zero and $46.1 million in impairment losses were recorded for the three and nine months ended September 30, 2012.

The Company’s estimated fair value of investment properties was based on a comparison of recent market activity and discounted cash flow models, which include estimates of property-specific inflows and outflows over a specific holding period.  Significant unobservable quantitative inputs used in determining the fair value of each investment property for the period ended September 30, 2013 include: a discount rate ranging from 5% to 9%; a capitalization rate ranging from 7.5% to 9.5%; stabilized occupancy rates ranging from 82% through 95%; and current market rental rates ranging from $4.25 per square foot to $12.50 per square foot.  These inputs are based on the location, type and nature of each property, current and anticipated market conditions, and management’s knowledge and expertise in real estate.

The Company’s estimated fair value of the investment properties in Minneapolis, Minnesota, Melville, New York and Seattle, Washington as of December 31, 2012 was based on a comparison of recent market activity and discounted cash flow models, which include estimates of property specific inflows and outflows over a specific holding period.  Significant unobservable quantitative inputs used in determining the fair value of each investment include: discount rates ranging from 8% through 13%; a capitalization rate of 8.5%; stabilized occupancy rates ranging from 82% through 93%; and current market rental rates ranging from $11.20 per square foot to $21.50 per square foot.  These inputs are based on the location, type and nature of each property, current and anticipated market conditions, and management’s knowledge and expertise in real estate.

[2]	The additional gain (loss) on sale of discontinued operations recorded in 2012 is primarily related to the settlement of reserves that were established during the closing of the sale of Atrium on Bay in June 2011.

'Due to deterioration in the financial condition at Douglas Corporate Center, the Core Fund elected to not make debt service payments on the secured, nonrecourse mortgage loan at the property.  This decision resulted in a default and a foreclosure on the property by the lender in January 2013.  As a result of the foreclosure, the Core Fund relinquished all rights and title to the property and was relieved of the entire value of the mortgage loan and recognized a gain of $12.6 million for the nine months ended September 30, 2013.

Variable Interest Entity Methodology For Determining Whether Enterprise Is Primary Beneficiary

'

'

'

'

'

'

'

'

'At September 30, 2013 and December 31, 2012, the Company’s investment in the Grocery-Anchored Portfolio was determined to be a variable interest entity (“VIE”) due to certain payment guarantees that result in the protection of the Company’s equity from expected losses. Further, the JV partner has the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and, as a result, the Company has determined it is not the primary beneficiary of this VIE.

In January 2013, a subsidiary of the Operating Partnership executed a new loan agreement with the Bank of China for a $200.0 million secured mortgage loan and repaid the original loan. In connection with the sale of One Wilshire, the Company retired the outstanding principal balance of the secured mortgage loan in July 2013 with a prepayment penalty of $2.0 million.

[2]

In April 2013, the Company paid down its mortgage secured by 2555 Grand using a bridge loan (the “JPMorgan Chase Bridge Loan”) with JPMorgan Chase Bank, N.A. (“JPMorgan Chase”). The JPMorgan Chase Bridge Loan was a six-month term loan with a maximum commitment of $86.0 million. In August 2013, the Company paid down the JPMorgan Chase Bridge Loan and is currently in negotiations to refinance the bridge loan to a permanent revolving credit facility with JPMorgan Chase with similar terms.

[3]

In connection with the sale of Williams Tower, the Company retired the outstanding principal balance of the secured mortgage loan in March 2013.

[4]

In connection with the sale of the Raytheon/DIRECTV buildings, the Company retired the outstanding principal balance of the secured mortgage loan in July 2013 and paid $7.8 million related to the defeasance of the loan pursuant to the terms of the underlying loan document.

[5]

In August 2013, the Company prepaid $31.0 million, the outstanding debt balance related to Seattle Design Center, and incurred a breakage fee of $5.4 million to terminate the related swap agreement with HSH Nordbank AG, New York Branch (“HSH Nordbank”).

[6]

In January 2013, the Company entered into an amended and restated promissory note for the $160.0 million outstanding principal balance related to JPMorgan Chase Tower.

[7]

In January 2013, the Company paid down its outstanding balance on its revolving line of credit prior to its maturity and did not renew it upon its expiration.

[8]

The Company assumed notes payable in connection with various acquisitions, which were recorded at their estimated fair value as of the date of acquisition. The difference between the fair value at acquisition and the principal outstanding is amortized over the term of the related note.

The Company records a liability related to the Participation Interest based on its estimated settlement value in the accompanying condensed consolidated balance sheets. This liability is remeasured at fair value based on the related redemption price in place as of each balance sheet plus any unpaid distributions. As described previously in Note 8 — Distributions, the Company declared an $0.80 special distribution (or $10.0 million, in total, to the Participation Interest) to all stockholders of the Company in March 2013, which represented a reduction in the Participation Interest liability to reflect a return of capital for the period ending March 31, 2013.

[2]

Excluded from this table are distributions declared with respect to the Participation Interest (as discussed further in Note 9 — Related Party Transactions). The amount of distributions declared with respect to the Participation Interest for the quarters ended September 30, 2013, June 30, 2013 and March 31, 2013 were $0.9 million, $0.9 million and $1.5 million, respectively. Included in the $226.1 million amount declared at March 31, 2013 above is the $10.0 million special distribution declared in March 2013 to the Participation Interest. The distributions declared with respect to the Participation Interest for the quarters ended December 31, 2012, September 30, 2012, June 30, 2012 and March 31, 2012 were $1.5 million, $1.4 million, $1.3 million and $1.3 million, respectively.

[3]

As stated above, a portion of the total distributions declared were designated by the Company as special distributions and funded using proceeds from sales of investment property, which represents a return of a portion of the stockholders and noncontrolling interests’ invested capital. For the nine months ended September 30, 2013, $206.7 million of the Company’s distributions declared were designated as special distributions, $198.0 million of which related to the one-time $0.80 per share special distribution described above. For the year ended December 31, 2012, $35.0 million of the total distributions declared to the Company’s stockholders and non-controlling interests were paid using such sales proceeds.
