Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	'
	1	Organization and Basis of Presentation
	Organization
	Glimcher Realty Trust (“GRT”) is a fully-integrated, self-administered and self-managed Maryland real estate investment trust (“REIT”), which owns, leases, manages and develops a portfolio of retail properties (the “Property” or “Properties”). The Properties consist of enclosed regional malls, open-air centers, outlet centers, and community shopping centers. At September 30, 2014, GRT both owned material interests in and managed 26 Properties (23 wholly-owned and three partially owned through joint ventures). The "Company" refers to GRT and Glimcher Properties Limited Partnership (the "Operating Partnership," "OP" or "GPLP"), a Delaware limited partnership, as well as entities in which the Company has a material ownership or financial interest, collectively.
	Basis of Presentation
	The consolidated financial statements include the accounts of GRT, GPLP, and Glimcher Development Corporation (“GDC”) and their subsidiaries.  As of September 30, 2014, GRT was a limited partner in GPLP with a 98.2% ownership interest and GRT’s wholly-owned subsidiary, Glimcher Properties Corporation, was GPLP’s sole general partner, with a 0.1% ownership interest in GPLP.  GDC, a wholly-owned subsidiary of GPLP, provides development, construction, leasing, and legal services to the Company’s affiliates and is a taxable REIT subsidiary.  The Company consolidates entities in which it owns more than 50% of the voting equity and control does not rest with other parties, as well as variable interest entities (“VIE”) in which it is deemed to be the primary beneficiary in accordance with Accounting Standards Codification (“ASC”) Topic 810 – “Consolidation.”  Investments in real estate joint ventures over which the Company has the ability to exercise significant influence, but for which it does not have financial or operating control, are accounted for using the equity method of accounting. These entities are reflected on the Company’s consolidated financial statements as “Investment in and advances to unconsolidated real estate entities.”  All significant intercompany accounts and transactions have been eliminated in the consolidated financial statements.
	The consolidated financial statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  The information furnished in the accompanying Consolidated Balance Sheets, Consolidated Statements of Comprehensive Income, Consolidated Statement of Equity, and Consolidated Statements of Cash Flows reflect all adjustments which are, in the opinion of management, recurring and necessary for a fair statement of the aforementioned financial statements for the interim period.  Operating results for the three and nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014.
	The December 31, 2013 balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP in the United States of America (“U.S.”).  The consolidated financial statements should be read in conjunction with the Notes to the Consolidated Financial Statements and Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s Form 10-K for the year ended December 31, 2013.
	Subsequent events that have occurred since September 30, 2014 that require recognition or disclosure in these consolidated financial statements are disclosed in Note 6 - "Investment in and Advances to Unconsolidated Real Estate Entities."

Significant Accounting Policies [Text Block]	'
	2.    Summary of Significant Accounting Policies
	The notes to the consolidated financial statements included in the Company's 2013 Annual Report on Form 10-K provide a detailed discussion of its critical accounting policies. There have been no material changes to these policies as of September 30, 2014.
	Supplemental Disclosure of Non-Cash Operating, Investing, and Financing Activities
	The Company's other non-cash activities for the nine months ended September 30, 2014 accounted for changes in the following areas: a) investment in real estate - $(39,684), b) cash in escrow $(1,109), c) investment in and advances to unconsolidated real estate entities - $3,401, d) accounts receivable - $(472), e) deferred costs - $1,345, f) prepaid and other assets - $378, g) mortgage notes payable - $40,796, h) accounts payable and accrued expenses - $(834), i) additional paid in capital - $177, j) accumulated other comprehensive loss - $(220), and k) redeemable noncontrolling interests - $(3,778).
	During the third quarter of 2014, the Company conveyed, without penalty, its interest in Eastland Mall located in Columbus, Ohio (“Eastland”) to the securitization trustee (the “Eastland Lender”) for the securitized mortgage loan that encumbered Eastland. In connection with this transfer, the Company disposed of assets totaling $24,014.

	Use of Estimates
	The preparation of financial statements in conformity with GAAP in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods.  Actual results could differ from those estimates.
	New Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in ASU 2014-08 change the criteria for reporting a discontinued operation and require new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. Only disposals representing a strategic shift in operations should be presented as discontinued operations.  This accounting standard update is effective for annual filings beginning on or after December 15, 2014. Early adoption is permitted. The impact of the adoption of ASU 2014-08 on the Company’s results of operations, financial position, cash flows and disclosures will be based on the Company’s future disposal activity.
	In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company is currently evaluating the new standard.
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40); Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”.  This update defines when and how companies are required to disclose going concern uncertainties, which must be evaluated each interim and annual period.  ASU 2014-15 requires management to determine whether substantial doubt exists regarding the entity’s going concern presumption.  This update is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter.  Early adoption is permitted.  The Company does not expect this standard to have an impact on the Company’s consolidated financial statements upon adoption.
	Reclassifications
	Certain reclassifications of prior period amounts, including the presentation of the Consolidated Statements of Comprehensive Income required by ASC Topic 205 - “Presentation of Financial Statements,” have been made in the consolidated financial statements in order to conform to the 2014 presentation.

Mergers, Acquisitions and Dispositions Disclosures [Text Block]	'
	3.    Washington Prime Group Merger
	On September 16, 2014, GRT and GPLP entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Washington Prime Group Inc. (“WPG”), Washington Prime Group, L.P. (“WPGLP”), WPG Subsidiary Holdings I, LLC (“Merger Sub I”) and WPG Subsidiary Holdings II Inc. (“Merger Sub II”), pursuant to which GRT will merge with and into Merger Sub I, which is a direct wholly-owned subsidiary of WPGLP (such transaction, the “Merger”). Upon completion of the Merger, WPG will conduct business under the name “WP GLIMCHER” and will use such name for all purposes, except as otherwise required by law or contract. At WPG's 2015 annual meeting of shareholders, the holders of WPG common shares will be asked to vote on a proposal to amend the WPG articles of incorporation to change the name of WPG to “WP GLIMCHER Inc.”
	Under the terms of the Merger Agreement, at the effective time of the Merger, each outstanding Common Share (other than certain Common Shares as set forth in the Merger Agreement) will be converted into the right to receive the Merger consideration, which consists of: (x) $10.40 in cash, without interest and (y) 0.1989 of a WPG common share. The total transaction value, including the assumption of debt, was approximately $4,300,000 as of September 15, 2014, assuming 0.1989 of a WPG common share is valued at $3.80 for purposes of determining the total transaction value, which value was determined by multiplying 0.1989 by the volume-weighted average closing price of WPG common shares on the ten trading days preceding the date the parties entered into the Merger Agreement. As a result of changes in the market price for WPG common shares, the final purchase price could differ significantly from such estimate.
	Additionally, (i) each outstanding Glimcher Series G Preferred Share will be converted into one share of 8.125% series G cumulative redeemable preferred stock, par value $0.0001 per share, of WPG (the “WPG Series G Preferred Shares”), (ii) each outstanding Series H Preferred Share will be converted into one share of 7.5% series H cumulative redeemable preferred stock, par value $0.0001 per share, of WPG (the “WPG Series H Preferred Shares”) and (iii) each outstanding Glimcher Series I Preferred Share will be converted into one share of 6.875% series I cumulative redeemable preferred stock, par value $0.0001 per share, of WPG (the “WPG Series I Preferred Shares”). In connection with the closing of the Merger, WPG plans to redeem all 4,700,000 WPG Series G Preferred Shares and anticipates sending a redemption notice to holders of the WPG Series G Preferred Shares on or shortly after the date of the closing of the Merger.
	GRT and GPLP have agreed to certain obligations and restrictions with respect to the conduct of the business of themselves and their subsidiaries until the earlier of the effective time of the Merger or the valid termination of the Merger Agreement.  The Merger Agreement contains certain restrictions on the Company’s ability to enter into contracts relating to capital expenditures, issue equity or incur, refinance, prepay, assume or guarantee indebtedness, which may include restrictions on transactions typically used to fund short and long-term liquidity requirements, unless prior written consent has been granted by WPG.
	The Merger Agreement also provides for the Merger of Merger Sub II with and into GPLP. At the effective time of such Merger (i) each outstanding limited partnership unit of GPLP (the “OP Units”) issued and outstanding immediately prior to such effective time (other than certain GPLP units as set forth in the Merger Agreement and the GPLP Series I-1 preferred limited partnership units as described below) will be converted into the right to receive 0.7431 of a newly issued, fully paid and non-assessable WPGLP unit and (ii) each GPLP Series I-1 Preferred Interests issued and outstanding immediately prior to such effective time will be converted into one preferred unit of WPGLP having the preferences, rights and privileges substantially identical to the preference, rights and privileges of the Series I-1 Preferred Interests prior to such Merger.
	Concurrent with the execution of the Merger Agreement, WPGLP and Simon Property Group, L.P. (“Simon LP”) entered into a Purchase and Sale Agreement (the “Purchase Agreement”), pursuant to which WPGLP will sell, or cause to be sold (i) the equity interests in the owner of Jersey Gardens, a regional mall in Elizabeth, New Jersey (“Jersey Gardens”) and (ii) the equity interests in the owner of University Park Village, an open air center in Fort Worth, Texas (“University Park”) to Simon LP for $1,090,000 (subject to certain adjustments and apportionments as described in the Purchase Agreement). The closing of such sale will occur substantially simultaneously with the completion of the Merger.
	Completion of the Merger is subject to, among other things, approval by the holders of the GRT Common Shares. WPG will cause the WPG Board of Directors ("WPG Board") immediately after the Merger to consist of nine members: (i) Mark Ordan (the current chief executive officer of WPG), (ii) Michael Glimcher (the current chairman of the board and chief executive officer of GRT), the other six members of the WPG Board as of September 16, 2014: Louis G. Conforti, Robert J. Laikin, David Simon, Jacquelyn R. Soffer, Richard S. Sokolov and Marvin L. White, and one additional trustee of GRT to be mutually agreed by Glimcher and WPG. Glimcher and WPG have agreed on Niles C. Overly as the additional trustee of GRT to serve on the WPG Board. Mark Ordan will be the executive chairman of WP GLIMCHER and Michael Glimcher will be the vice chairman, chief executive officer and president of WP GLIMCHER. Following the closing, the corporate headquarters and operations for WPG and its subsidiaries will be in Columbus, Ohio. The Merger is expected to be completed during the first quarter of 2015.

	5	Investment in Joint Ventures – Consolidated
	As of September 30, 2014, the Company has an interest in three consolidated joint ventures. The VBF Venture qualifies as a VIE under ASC Topic 810 and the Company is the primary beneficiary of this joint venture. The Company has determined that neither the Arbor Hills Venture nor the OKC Venture, as defined below, are VIE's. The Arbor Hills Venture and the OKC Venture are consolidated because the Company holds a controlling financial interest and the noncontrolling interests do not have substantive participating rights.
	Sold Assets
	•	Surprise Venture
	This investment consisted of a 50% interest held by a GPLP subsidiary in the Surprise Venture with the former landowner of the real property. The Surprise Venture previously owned and operated Town Square at Surprise (“Surprise”), a community shopping center located in Surprise, Arizona.
	During the nine months ended September 30, 2014, the Surprise Venture sold the remaining 1.3 acre parcel of undeveloped land located at Surprise to an unaffiliated third party. The land was sold for $900 and the Company recorded a gain on the sale of $372. Also, during the nine months ended September 30, 2014, the Surprise Venture sold the multi-tenant building at Surprise to an unaffiliated third party, for a sales price of $2,754 and recorded a gain on the sale in the amount of $1,004. The proceeds from this sale were used to repay both the mortgage loan on Surprise as well as the loan made by GPLP to the Surprise Venture.
	As of September 30, 2014, the Surprise Venture no longer owns any real estate assets.
	Variable Interest Entities
	•	VBF Venture
	On October 5, 2007, an affiliate of the Company entered into an agreement with an unaffiliated third party to form the VBF Venture. The Company contributed $5,000 in cash for a 50% interest in the VBF Venture. The economics of the VBF Venture require that the Company receive a preferred return and 75% of the distributions from the VBF Venture until such time as the capital contributed by the Company is returned. As discussed in Note 4 - "Real Estate Assets Held-for-Sale," the Company has listed the undeveloped land held by the VBF Venture as held-for-sale.
	The Company did not provide any additional financial support to the VBF Venture during the nine months ended September 30, 2014.  Furthermore, the Company does not have any contractual commitments or obligations to provide additional financial support to the VBF Venture.
	The carrying amounts and classification on the Company's Consolidated Balance Sheets of the total assets and liabilities, which consist of only the VBF Venture at September 30, 2014 and consisted of both the Surprise Venture and the VBF Venture at December 31, 2013, are as follows:
			September 30,		December 31,
			2014		2013
	Real estate assets held-for-sale		$	3,658	$	5,667
	Total assets		$	3,658	$	5,718
	Mortgage note payable associated with property held-for-sale		$	—	$	1,330
	Total liabilities		$	8	$	1,419
	The VBF Venture is a separate legal entity, and is not liable for the debts of the Company.  Accordingly, creditors of the Company may not satisfy their debts from the assets of the VBF Venture, except as permitted by applicable law or regulation, or by agreement. Also, creditors of the VBF Venture may not satisfy their debts from the assets of the Company, except as permitted by applicable law or regulation, or by agreement.
	Other Joint Ventures - Consolidated
	•	Arbor Hills Venture
	On December 18, 2013, an affiliate of the Company acquired an approximate 93% interest in Arbor Hills, an approximate 87,000 square foot open-air center located in Ann Arbor, Michigan, for $52,550. This investment is held by a GPLP subsidiary in a joint venture (the "Arbor Hills Venture") with two unaffiliated entities.
	•	OKC Venture
	On February 28, 2014, an affiliate of the Company acquired a 99% interest in approximately 290,000 square feet of open-air mixed-use properties in the Oklahoma City, Oklahoma area for $51,820 (the "OKC Venture"). The purchase includes contiguous retail properties and approximately 12 acres of land. The retail Properties primarily include Nichols Hills Plaza, Classen Curve, and The Triangle @ Classen Curve, (collectively the "OKC Properties"). This investment is held by a GPLP subsidiary in the OKC Venture with an unaffiliated entity.
	The noncontrolling interests in both the Arbor Hills Venture and the OKC Venture are redeemable at the option of the holders under certain circumstances according to the terms of the respective joint venture agreements. These noncontrolling interests are presented as redeemable noncontrolling interests outside of permanent equity on the Company's Consolidated Balance Sheets. The Company adjusts the carrying amount of the redeemable noncontrolling interests to their maximum redemption value at the end of each reporting period, after allocating their pro-rata amount of net income (loss) and any contributions received, or distributions to, the redeemable noncontrolling interests. Changes in the redemption value of the redeemable noncontrolling interests are recorded within shareholder’s equity. Future reductions in the carrying amounts are limited to the original recorded fair value of the redeemable noncontrolling interests. The Company estimates the maximum redemption amounts based upon the terms of the applicable joint venture agreement, using variables such as: expected market capitalization rates, discount rates, and estimated future cash flows.

	On February 13, 2014, GPLP closed on a modification and extension of its unsecured corporate credit facility (as amended, the “Credit Facility”). The Credit Facility amended the unsecured credit facility that was due to expire in February 2017 (the “Prior Facility”). The modification increased the maximum availability under the Credit Facility from $250,000 to $300,000 and extended the facility's maturity date to February 2018 with an additional one-year extension option. The Credit Facility provides for improved pricing through a lower interest rate structure. The interest rate ranges from LIBOR plus 1.40% to LIBOR plus 2.00% per annum based upon the quarterly measurement of our consolidated debt outstanding as a percentage of total asset value. The applicable interest rate as of September 30, 2014 is LIBOR plus 1.75% per annum, or 1.91% per annum. GPLP may increase the total borrowing availability to $500,000 under an accordion feature. The Company's availability under the Credit Facility is determined based upon the value of its unencumbered assets and is measured on a quarterly basis. The Credit Facility contains customary covenants, representations, warranties and events of default, including maintenance of a specified net worth requirement; a consolidated debt outstanding as a percentage of total asset value ratio; an interest coverage ratio; a fixed charge ratio; and a total recourse debt outstanding as a percentage of total asset value ratio.  Management believes GPLP is in compliance with all covenants of the Credit Facility as of September 30, 2014.
	At September 30, 2014, the availability level on the Credit Facility was $300,000 and the outstanding balance was $133,000.  Additionally, $627 represents a holdback on the available balance for letters of credit issued under the Credit Facility.  As of September 30, 2014, the unused balance of the Credit Facility available to the Company was $166,373 and the average interest rate on the outstanding balance was 1.91% per annum.

	11	Derivative Financial Instruments
	Risk Management Objective of Using Derivatives
	The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its debt funding and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash payments related to the Company's borrowings.
	Cash Flow Hedges of Interest Rate Risk
	The Company's objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company has elected to designate all interest rate swaps as cash flow hedging relationships.
	The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in “Accumulated other comprehensive loss” (“OCL”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. During the nine months ended September 30, 2014 and 2013, such derivatives were used to hedge the variable cash flows associated with our existing variable-rate debt. Any ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. The Company had no hedge ineffectiveness in earnings during the three and nine months ended September 30, 2014 and 2013.
	Amounts reported in OCL relate to derivatives that will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. During the next twelve months, the Company estimates that an additional $327 will be reclassified as an increase to interest expense.
	As of September 30, 2014, the Company had two outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk with a notional value of $125,000.
	The table below presents the fair value of the Company's derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of September 30, 2014 and December 31, 2013:

		Balance Sheet		Fair			Balance Sheet		Fair
		Location		Value			Location		Value
	Derivatives designated as hedging instruments:
	Interest Rate Products	Accounts payable and accrued expenses		$	294		Accounts payable and accrued expenses		$	514
	The derivative instruments were reported at their fair value of $294 and $514 in accounts payable and accrued expenses at September 30, 2014 and December 31, 2013, respectively, with a corresponding adjustment to OCL for the unrealized gains and losses (net of noncontrolling interest allocation). Over time, the unrealized gains and losses held in OCL will be reclassified to earnings. This reclassification will correlate with the recognition of the hedged interest payments in earnings.
	The table below presents the effect of the Company's derivative financial instruments on the Consolidated Statements of Comprehensive Income for the three months ended September 30, 2014 and 2013:

The Company allocated $2 of OCL to noncontrolling interest during the three months ended September 30, 2014.
	During the three months ended September 30, 2013, the Company recognized other comprehensive loss on derivative instruments of $34, to adjust the carrying amount of the interest rate swaps to their fair values at September 30, 2013, net of $122 in reclassifications to earnings for interest rate swap settlements during the period.

	During the nine months ended September 30, 2014, the Company recognized other comprehensive income of $224, to adjust the carrying amount of the interest rate swaps to their fair values at September 30, 2014, net of $389 in reclassifications to earnings for interest rate swap settlements during the period. The Company allocated $4 of other comprehensive income to noncontrolling interests during the nine months ended September 30, 2014.
	During the nine months ended September 30, 2013, the Company recognized other comprehensive income on derivative instruments of $203, to adjust the carrying amount of the interest rate swaps to their fair values at September 30, 2014, net of $354 in reclassifications to earnings for interest rate swap settlements during the period. The Company allocated $4 of other comprehensive income to noncontrolling interests during the nine months ended September 30, 2013.
	Non-designated Hedges
	The Company does not use derivatives for trading or speculative purposes and currently has one interest rate cap with a notional amount of $102,500 that is not designated as a cash flow hedge. Changes in the fair value for derivatives not designated in hedging relationships are recorded in interest expense and were equal to $0 and $4 for the three months ended September 30, 2014 and September 30, 2013, respectively, and $4 and $(6) for the nine months ended September 30, 2014 and September 30, 2013, respectively.
	Credit Risk-related Contingent Features
	The Company has agreements with each of its derivative counterparties that contain a provision that if the Company either defaults or is capable of being declared in default on any of its consolidated indebtedness, then the Company could also be declared in default on its derivative obligations.
	The Company has agreements with its derivative counterparties that incorporate the loan covenant provisions of the Company's indebtedness with a lender affiliate of the derivative counterparty. Failure to comply with the loan covenant provisions would result in the Company being in default on any derivative instrument obligations covered by the agreement.
	As of September 30, 2014, the fair value of derivatives in a net liability position, plus accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $342. As of September 30, 2014, the Company has not posted any collateral related to these agreements. The Company is not in default with any of these provisions. If the Company had breached any of these provisions at September 30, 2014, it would have been required to settle its obligations under the agreements at their termination value of $341.

Disclosure Text Block [Abstract]	'
Derivatives and Fair Value [Text Block]	'
	12	Fair Value Measurements
	The Company measures and discloses its fair value measurements in accordance with ASC Topic 820 - “Fair Value Measurements and Disclosure” (“Topic 820”). Topic 820 guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement.  Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability.  As a basis for considering market participant assumptions in fair value measurements, Topic 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).  The fair value hierarchy, as defined by Topic 820, contains three levels of inputs that may be used to measure fair value as follows:
	•	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access.
	•	Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly such as interest rates, foreign exchange rates, and yield curves, that are observable at commonly quoted intervals.
	•	Level 3 inputs are unobservable inputs for the asset or liability which are typically based on an entity's own assumptions, as there is little, if any, related market activity.
	In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.
	The Company has derivatives that must be measured under the fair value standard. The Company currently does not have any non-financial assets and non-financial liabilities that are required to be measured at fair value on a recurring basis.
	Derivative financial instruments
	Currently, the Company uses interest rate swaps and caps to manage its interest rate risk. The valuation of these instruments is determined 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, foreign exchange rates, and implied volatilities. Based on these inputs the Company has determined that its interest rate swap and cap valuations are classified within Level 2 of the fair value hierarchy.
	To comply with the provisions of Topic 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value 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, mutual puts, and guarantees.
	Although the Company has determined that 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 itself and its counterparties. However, as of September 30, 2014, 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 valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy.
	Recurring Valuations
	The Company values its derivative instruments, net using significant other observable inputs (Level 2).
	Nonrecurring Valuations
	During the nine months ended September 30, 2014, the Company reduced the carrying value of Eastland to its estimated net realizable value and recorded a $2,513 impairment loss. The Company used multiple market indicators in determining the Property’s estimated fair value. Eastland was disposed of during the three months ended September 30, 2014.
	The table below presents the Company’s liabilities measured at fair value as of September 30, 2014 and December 31, 2013, aggregated by the level in the fair value hierarchy within which those measurements fall:

	Restricted Common Stock
	Outstanding shares of restricted Common Stock have been granted pursuant to GRT’s 2004 Amended and Restated Incentive Compensation Plan and the GRT 2012 Incentive Compensation Plan (the "2012 Plan"). The restricted Common Stock value is determined by the Company’s closing market share price on the grant date. As restricted Common Stock represents an incentive for future periods, the Company recognizes the related compensation expense ratably over the applicable vesting periods. During the nine months ended September 30, 2014, the Company granted 540,166 restricted Common Shares. Of this amount, 186,466 restricted Common Shares vest in one-third installments over a period of five years beginning on the third anniversary of the grant date, 38,952 restricted Common Shares vest in one-third installments over a period of three years beginning on the first anniversary of the grant date, and 314,748 restricted Common Shares vest on the fifth anniversary of the date of the grant. During the nine months ended September 30, 2013, the Company granted 194,391 restricted Common Shares.
	The compensation expense for all restricted Common Shares was $919 and $790 for the three months ended September 30, 2014 and 2013, respectively, and $2,684 and $2,265 for the nine months ended September 30, 2014 and 2013, respectively. The amount of compensation expense related to unvested restricted Common Shares that the Company expects to expense in future periods, over a weighted average period of 3.6 years, is $13,116 as of September 30, 2014.
	Stock Option Plans
	Options granted under the Company’s share option plans generally vest over a three-year period, with options exercisable at a rate of 33.3% per annum beginning with the first anniversary of the grant date. The options generally expire on the tenth anniversary of the grant date. The fair value of each option grant is estimated on the date of the grant using the Black-Scholes options pricing model and is amortized over the requisite vesting period. During the nine months ended September 30, 2014 and 2013, the Company issued 320,000 and 314,500 options, respectively. The fair value of each option granted in 2014 was calculated on the date of the grant with the following assumptions: weighted average risk free interest rate of 1.65%, expected life of five years, annual dividend rates of $0.40, and weighted average volatility of 35.9%. The weighted average fair value of options issued during the nine months ended September 30, 2014 was $2.32 per share. Compensation expense recorded for the Company’s share option plans was $275 and $310 for the three months ended September 30, 2014 and 2013, respectively, and $829 and $828 for the nine months ended September 30, 2014 and 2013, respectively.
	Performance Shares
	During the nine months ended September 30, 2014, GRT allocated 186,466 performance shares (the "2014 Performance Shares") to its senior executive officers under the 2012 Plan. Under the terms of the award agreement for each respective grant, a 2012 Plan participant’s allocation of performance shares are convertible into Common Shares as determined by the outcome of GRT’s relative total shareholder return (“TSR”) for its Common Shares during the period of January 1, 2014 to December 31, 2016 (the “2014 Performance Period”), as compared to the TSR for the common shares of a selected group of twenty-two retail-oriented REITs.
	The compensation expense recorded for performance shares was calculated in accordance with ASC Topic 718 - “Compensation-Stock Compensation.” The fair value of the unearned portion of the performance share awards was determined utilizing the Monte Carlo simulation technique and will be amortized to compensation expense over the 2014 Performance Period. The fair value of the 2014 Performance Shares was determined to be $9.51 per share for a total compensation amount of $1,773 to be recognized over the 2014 Performance Period.
	The amount of compensation expense related to all outstanding performance shares was $503 and $429 for the three months ended September 30, 2014 and 2013, respectively, and $1,225 and $1,042 for the nine months ended September 30, 2014 and 2013, respectively.

	The Company has provided a limited guarantee of franchise tax payments to be received by the City of Elizabeth, New Jersey (the "City") until franchise tax payments achieve $5,600 annually.  Through September 30, 2014, the Company has made $17,560 in payments under this guarantee agreement. During 2010, the Company was relieved from its limited guarantee of franchise taxes. The guarantee agreement allows the Company to recover payments made under the guaranty plus interest at LIBOR plus 2.00% per annum.  The reimbursement will occur from any excess assessments collected by the City above specified annual levels over the franchise assessment period of 30 years. Fifty percent of excess taxes collected over the $5,600 annual threshold will be paid by the City to the Company each year that the taxes collected exceed the threshold, until such time that the Company has recovered all previous guaranty payments plus LIBOR plus 2.00% per annum or the end of the franchise period is reached. As of September 30, 2014, the initial payment of $352 is due from the City. Based upon projected franchise tax collections during the guarantee period, the Company expects to recover at least $15,032 before the guarantee period ends in 2030.  Accordingly, this $15,032 is included in “Prepaid and other assets” in the Consolidated Balance Sheets as of September 30, 2014 and December 31, 2013.

	Intangible assets and liabilities as of September 30, 2014, which were recorded at the respective acquisition dates, are associated with acquisitions of Polaris Fashion Place, located in Columbus, Ohio, Merritt Square Mall, located in Merritt Island, Florida, Town Center Plaza and Town Center Crossing, both located in Leawood, Kansas, Pearlridge Center, located in Aiea, Hawaii, Malibu Lumber Yard, located in Malibu, California, University Park, WestShore, Arbor Hills, and the OKC Properties.
	The gross intangibles recorded as of their respective acquisition dates are comprised of an asset for acquired above-market leases of $19,330 in which the Company is the lessor, a liability for acquired below-market leases of $87,042 in which the Company is the lessor, an asset of $12,571 for an acquired below-market lease in which the Company is the lessee, a liability of $8,102 for an acquired above-market lease in which the Company is the lessee, an asset for tenant relationships of $2,689, and an asset for in-place leases for $74,065.
	The intangibles related to above and below-market leases in which the Company is the lessor are amortized to minimum rents on a straight-line basis over the estimated life of the lease. The above and below-market leases in which the Company is the lessee are amortized to other operating expenses over the life of the non-cancelable lease terms. Tenant relationships are amortized to depreciation and amortization expense over the remaining estimated useful life of the tenant relationship. In-place leases are amortized to depreciation and amortization expense over the life of the leases to which they pertain.
	Net amortization for all of the acquired intangibles is a decrease to net income in the amount of $741 and $2,102 for the three months ended September 30, 2014 and 2013, respectively, and $4,301 and $5,209 for the nine months ended September 30, 2014 and 2013, respectively.
	The table below identifies the type of intangible assets, their location on the Consolidated Balance Sheets, their weighted average amortization period, and their book value, which is net of accumulated amortization, as of September 30, 2014 and December 31, 2013:

	18	Fair Value of Financial Instruments
	The carrying values of cash and cash equivalents, restricted cash, tenant accounts receivable, accounts payable and accrued expenses are reasonable estimates of their fair values because of the short maturity of these financial instruments.  The carrying value of the Credit Facility is also a reasonable estimate of its fair value because it bears variable rate interest at current market rates.  Based on the discounted amount of future cash flows using rates currently available to GRT for similar liabilities (ranging from 2.98% to 6.00% per annum at September 30, 2014 and 3.06% to 6.00% per annum at December 31, 2013), the fair value of GRT's mortgage notes payable is estimated at $1,707,173 and $1,838,389 at September 30, 2014 and December 31, 2013, respectively, compared to its carrying amounts of $1,702,425 and $1,847,903, respectively.  The fair value of the debt instruments considers, in part, the credit of GRT as an entity and not just the individual entities and Properties owned by GRT. Fair value of debt was estimated using cash flows discounted at current market rates, as estimated by management. When determining current market rates for purposes of estimating the fair value of debt, the Company employed adjustments to the original credit spreads used when the debt was originally issued to account for current market conditions.

Use of Estimates, Policy [Policy Text Block]	'
	Use of Estimates
	The preparation of financial statements in conformity with GAAP in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods.  Actual results could differ from those estimates.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	New Accounting Pronouncements
	In April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in ASU 2014-08 change the criteria for reporting a discontinued operation and require new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. Only disposals representing a strategic shift in operations should be presented as discontinued operations.  This accounting standard update is effective for annual filings beginning on or after December 15, 2014. Early adoption is permitted. The impact of the adoption of ASU 2014-08 on the Company’s results of operations, financial position, cash flows and disclosures will be based on the Company’s future disposal activity.
	In May 2014, FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements in “Revenue Recognition (Topic 605),” and requires an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and is to be applied retrospectively, with early application not permitted. The Company is currently evaluating the new standard.
	In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40); Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern”.  This update defines when and how companies are required to disclose going concern uncertainties, which must be evaluated each interim and annual period.  ASU 2014-15 requires management to determine whether substantial doubt exists regarding the entity’s going concern presumption.  This update is effective for the annual period ending after December 15, 2016, and for annual and interim periods thereafter.  Early adoption is permitted.  The Company does not expect this standard to have an impact on the Company’s consolidated financial statements upon adoption.
Reclassification, Policy [Policy Text Block]	'
	Reclassifications
	Certain reclassifications of prior period amounts, including the presentation of the Consolidated Statements of Comprehensive Income required by ASC Topic 205 - “Presentation of Financial Statements,” have been made in the consolidated financial statements in order to conform to the 2014 presentation.
