Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies
	Ramco-Gershenson Properties Trust, together with our subsidiaries (the “Company”), is a real estate investment trust (“REIT”) engaged in the business of owning, developing, redeveloping, acquiring, managing and leasing large multi-anchored shopping centers primarily in a dozen of the largest metropolitan markets in the United States.  Our property portfolio consists of 67 wholly owned shopping centers and one office building comprising approximately 14.2 million square feet.  In addition, we are co-investor in and manager of two institutional joint ventures that own portfolios of shopping centers.  We own 20% of Ramco 450 Venture LLC, an entity that owns eight shopping centers comprising approximately 1.7 million square feet and 30% of Ramco/Lion Venture L.P., an entity that owns three shopping centers comprising approximately 0.8 million square feet. We also have ownership interests in two smaller joint ventures that each own a shopping center.  Our joint ventures are reported using equity method accounting.  We earn fees from the joint ventures for managing, leasing, and redeveloping the shopping centers they own.  We also own interests in three parcels of land available for development and five parcels of land available for sale.
	We made an election to qualify as a REIT for federal income tax purposes.  Accordingly, we generally will not be subject to federal income tax, provided that we annually distribute at least 90% of our taxable income to our shareholders and meet other conditions.
	Principles of Consolidation and Estimates
	The consolidated financial statements include the accounts of us and our majority owned subsidiary, the Operating Partnership, Ramco-Gershenson Properties, L.P. (97.2%, 96.8% and 95.4% owned by us at December 31, 2014, 2013 and 2012, respectively), and all wholly-owned subsidiaries, including entities in which we have a controlling interest or have been determined to be the primary beneficiary of a variable interest entity (“VIE”).  The presentation of consolidated financial statements does not itself imply that assets of any consolidated entity (including any special-purpose entity formed for a particular project) are available to pay the liabilities of any other consolidated entity, or that the liabilities of any other consolidated entity (including any special-purpose entity formed for a particular project) are obligations of any other consolidated entity.  Investments in real estate joint ventures over which we have the ability to exercise significant influence, but for which we do not have financial or operating control, are accounted for using the equity method of accounting.  Accordingly, our share of the earnings (loss) of these joint ventures is included in consolidated net income (loss).  All intercompany transactions and balances are eliminated in consolidation.
	We own 100% of the non-voting and voting common stock of Ramco-Gershenson, Inc. (“Ramco”), and therefore it is included in the consolidated financial statements.  Ramco has elected to be a taxable REIT subsidiary for federal income tax purposes.  Ramco provides property management services to us and to other entities, including our real estate joint venture partners.
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts that are not readily apparent from other sources.  Actual results could differ from those estimates.
	Reclassifications
	Certain reclassifications of prior period amounts have been made in the financial statements in order to conform to the 2014 presentation.
	Revenue Recognition and Accounts Receivable
	Our shopping center space is generally leased to retail tenants under leases that are classified as operating leases. We recognize minimum rents using the straight-line method over the terms of the leases commencing when the tenant takes possession of the space or when construction of landlord funded improvements is substantially complete. Certain of the leases also provide for contingent percentage rental income which is recorded on an accrual basis once the specified target that triggers this type of income is achieved. The leases also provide for reimbursement from tenants for common area maintenance (“CAM”), insurance, real estate taxes and other operating expenses ("Recovery Income"). The majority of our Recovery Income is estimated and recognized as revenue in the period the recoverable costs are incurred or accrued.  Revenues from management, leasing, and other fees are recognized in the period in which the services have been provided and the earnings process is complete. Lease termination income is recognized when a lease termination agreement is executed by the parties and the tenant vacates the space.  When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement.
	Current accounts receivable from tenants primarily relate to contractual minimum rent, percentage rent and Recovery Income.
	We provide for bad debt expense based upon the allowance method of accounting. We monitor the collectability of our accounts receivable from specific tenants on an ongoing basis, analyze historical bad debts, customer creditworthiness, current economic trends and changes in tenant payment terms when evaluating the adequacy of the allowance for bad debts.  Allowances are taken for those balances that we have reason to believe may be uncollectible.  When tenants are in bankruptcy, we make estimates of the expected recovery of pre-petition and post-petition claims.  The period to resolve these claims can exceed one year.  Management believes the allowance for doubtful accounts is adequate to absorb currently estimated bad debts.  However, if we experience bad debts in excess of the allowance we have established, our operating income would be reduced.  At December 31, 2014 and 2013, our accounts receivable were $12.0 million and $9.6 million, respectively, net of allowances for doubtful accounts of $2.3 million and $2.4 million, respectively.
	In addition, many of our leases contain non-contingent rent escalations for which we recognize income on a straight-line basis over the non-cancelable lease term.  This method results in rental income in the early years of a lease being higher than actual cash received, creating a straight-line rent receivable asset which is included in the “Other assets, net” line item in our consolidated balance sheets.  We review our unbilled straight-line rent receivable balance to determine the future collectability of revenue that will not be billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors.  Our evaluation is based on our assessment of tenant credit risk changes indicating that expected future straight-line rent may not be realized.  Depending on circumstances, we may provide a reserve against the previously recognized straight-line rent receivable asset for a portion, up to its full value, that we estimate may not be received.  The balance of straight-line rent receivable at December 31, 2014 and 2013, net of allowances was $15.8 million and $15.1 million, respectively.  To the extent any of the tenants under these leases become unable to pay their contractual cash rents, we may be required to write down the straight-line rent receivable from those tenants, which would reduce our operating income.
	Real Estate
	Real estate assets that we own directly are stated at cost less accumulated depreciation.  Depreciation is computed using the straight-line method.  The estimated useful lives for computing depreciation are generally 10 – 40 years for buildings and and improvements and 5 – 30 years for parking lot surfacing and equipment.  We capitalize all capital improvement expenditures associated with replacements and improvements to real property that extend its useful life and depreciate them over their estimated useful lives ranging from 15 – 25 years.  In addition, we capitalize qualifying tenant leasehold improvements and depreciate them over the useful life of the improvements or the term of the related tenant lease.  We also capitalize direct internal and external costs of procuring leases and amortize them over the base term of the lease.  If a tenant vacates before the expiration of its lease, we charge unamortized leasing costs and undepreciated tenant leasehold improvements of no future value to expense.  We charge maintenance and repair costs that do not extend an asset’s life to expense as incurred.
	Sale of a real estate asset is recognized when it is determined that the sale has been consummated, the buyer’s initial and continuing investment is adequate, our receivable, if any, is not subject to future subordination, and the buyer has assumed the usual risks and rewards of ownership of the asset. We will classify properties as held for sale when executed purchase and sales agreement contingencies have been satisfied thereby signifying that the sale is guaranteed and legally binding.
	We allocate the costs of acquisitions to assets acquired and liabilities assumed based on estimated fair values, replacement costs and appraised values.  The purchase price of the acquired property is allocated to land, building, improvements and identifiable intangibles such as in-place leases, above/below market leases, out-of-market assumed mortgages, and gain on purchase, if any.  The value allocated to above/below market leases is amortized over the related lease term and included in rental income in our consolidated statements of operations. Should a tenant terminate its lease prior to its stated expiration, all unamortized amounts relating to that lease would be written off.
	Real estate also includes costs incurred in the development of new operating properties and the redevelopment of existing operating properties.  These properties are carried at cost and no depreciation is recorded on these assets until the commencement of rental revenue or no later than one year from the completion of major construction.  These costs include pre-development costs directly identifiable with the specific project, development and construction costs, interest, real estate taxes and insurance.  Interest is capitalized on land under development and buildings under construction based on the weighted average rate applicable to our borrowings outstanding during the period and the weighted average balance of qualified assets under development/redevelopment during the period.  Indirect project costs associated with development or construction of a real estate project are capitalized until the earlier of one year following substantial completion of construction or when the property becomes available for occupancy.
	The capitalized costs associated with development and redevelopment projects are depreciated over the useful life of the improvements.  If we determine a development or redevelopment project is no longer probable, we expense all capitalized costs which are not recoverable.
	It is our policy to start vertical construction on new development projects only after the project has received entitlements, significant anchor leasing commitments, construction financing and joint venture partner commitments, if appropriate.  We are in the entitlement and pre-leasing phases at our development projects.
	Accounting for the Impairment of Long-Lived Assets
	We review our investment in real estate, including any related intangible assets, for impairment on a property-by-property basis whenever events or changes in circumstances indicate that the carrying value of the property may not be recoverable.  These changes in circumstances include, but are not limited to, changes in occupancy, rental rates, tenant sales, net operating income, real estate values and expected holding period.  The viability of all projects under construction or development, including those owned by unconsolidated joint ventures, are regularly evaluated under applicable accounting requirements, including requirements relating to abandonment of assets or changes in use.  To the extent a project, or individual components of the project, are no longer considered to have value, the related capitalized costs are charged against operations.
	Impairment provisions resulting from any event or change in circumstances, including changes in management’s intentions or management’s analysis of varying scenarios, could be material to our consolidated financial statements.
	We recognize an impairment of an investment in real estate when the estimated undiscounted cash flow is less than the net carrying value of the property.  If it is determined that an investment in real estate is impaired, then the carrying value is reduced to the estimated fair value as determined by cash flow models and discount rates or comparable sales in accordance with our fair value measurement policy. Refer to Note 6 of the notes to the consolidated financial statements for further information.
	In 2014, we recorded impairment provisions totaling $27.9 million consisting of:
	•	$23.3 million related to certain parcels of land available for development or sale due to changes in plans or in fair value estimates; and
	•	$4.6 million of related to income producing properties that we have identified to be marketed for sale.
	Investments in Real Estate Joint Ventures
	We have four equity investments in unconsolidated joint venture entities in which we own 30% or less of the total ownership interest.  Because we can influence but not make significant decisions without our partners' approval, these investments are accounted for under the equity method of accounting. We provide leasing, development, asset and property management services to these joint ventures for which we are paid fees.  Refer to Note 7 of the notes to the consolidated financial statements for further information.
	We review our equity investments in unconsolidated entities for impairment on a venture-by-venture basis whenever events or changes in circumstances indicate that the carrying value of the equity investment may not be recoverable. In testing for impairment of these equity investments, we primarily use cash flow models, discount rates, and capitalization rates to estimate the fair value of properties held in joint ventures, and mark the debt of the joint ventures to market.  Considerable judgment by management is applied when determining whether an equity investment in an unconsolidated entity is impaired and, if so, the amount of the impairment. Changes to assumptions regarding cash flows, discount rates, or capitalization rates could be material to our consolidated financial statements.
	There were no impairment provisions on our equity investments in joint ventures recorded in 2014.
	Other Assets, net
	Other assets consist primarily of acquired lease intangibles, straight-line rent receivable, deferred leasing costs, deferred financing costs and prepaid expenses. Other assets also include the the fair value of in-place public improvement fee income and real estate tax exemption agreements associated with two properties acquired in 2014. Deferred financing and leasing costs are amortized using the straight-line method over the terms of the respective agreements. Should a tenant terminate its lease, the unamortized portion of the leasing cost is expensed.  Unamortized financing costs are expensed when the related agreements are terminated before their scheduled maturity dates.  We review our unbilled straight-line rent receivable balance to determine the future collectability of revenue that will not be billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors.  Our evaluation is based on our assessment of tenant credit risk changes indicating that expected future straight-line rent may not be realized.  Depending on circumstances, we may provide a reserve against the previously recognized straight-line rent receivable asset for a portion, up to its full value, that we estimate may not be received.
	Cash and Cash Equivalents
	We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents.  Cash balances in individual banks may exceed the federally insured limit by the Federal Deposit Insurance Corporation (the “FDIC”).  As of December 31, 2014, we had $12.7 million in excess of the FDIC insured limit.
	Recognition of Share-based Compensation Expense
	We grant share-based compensation awards to employees and trustees in the form of restricted common shares and in the past we have granted stock options to employees and trustees.  Our share-based award costs are equal to each grant date fair value and are recognized over the service periods of the awards using the graded vesting method.  See Note 16 of the notes to the consolidated financial statements for further information.
	Income Tax Status
	We made an election to qualify, and believe our operating activities permit us to qualify as a REIT for federal income tax purposes.  Accordingly, we generally will not be subject to federal income tax, provided that we distribute at least 90% of our taxable income annually to our shareholders and meet other conditions.  We are obligated to pay state taxes, generally consisting of franchise or gross receipts taxes in certain states which are not material to our consolidated financial statements.
	Certain of our operations, including property and asset management, as well as ownership of certain land parcels, are conducted through taxable REIT subsidiaries, (“TRSs”) which are subject to federal and state income taxes.  During the years ended December 31, 2014, 2013, and 2012, we sold various properties and land parcels at a gain, resulting in both a federal and state tax liability.  See Note 17 of the notes to the consolidated financial statements for further information.
	Variable Interest Entities
	Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as VIEs.  VIEs are required to be consolidated by their primary beneficiary.  The primary beneficiary of a VIE has both (i) the power to direct the activities that most significantly impact economic performance of the VIE, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.
	We have evaluated our investments in joint ventures and determined that the joint ventures do not meet the requirements of a VIE and, therefore, consolidation of these ventures is not required.  Accordingly, these investments are accounted for using the equity method.
	Noncontrolling Interest in Subsidiaries
	There are third parties who have certain noncontrolling interests in subsidiaries that are exchangeable for our common shares on a 1:1 basis or cash, at our election.   Noncontrolling interest is classified as a separate component of equity outside of the permanent equity section of our consolidated balance sheets.  Consolidated net income and comprehensive income includes the noncontrolling interest’s share.  The calculation of earnings per share is based on income available to common shareholders.
	Segment Information
	Our primary business is the ownership, management, redevelopment, development and operation of retail shopping centers.  We do not distinguish our primary business or group our operations on a geographical basis for purposes of measuring performance.  We review operating and financial data for each property on an individual basis and define an operating segment as an individual property.  The individual properties have been aggregated into one reportable segment based upon their similarities with regard to both the nature and economics of the centers, tenants and operational processes, as well as long-term financial performance.  No one individual property constitutes more than 10% of our revenue or property operating income and none of our shopping centers are located outside the United States.   Accordingly, we have a single reportable segment for disclosure purposes.

Accounting Changes and Error Corrections [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In June 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU 2014-12”). The amendments in ASU 2014-12 require that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Accounting Standards Codification Topic No. 718, “Compensation — Stock Compensation” (“ASC 718”), as it relates to awards with performance conditions that affect vesting to account for such awards. The amendments in ASU 2014-12 are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Early adoption is permitted. Entities may apply the amendments in ASU 2014-12 either: (a) prospectively to all awards granted or modified after the effective date; or (b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We believe the adoption of this guidance will not have a material effect on our consolidated financial statements.
	In May 2014, the FASB issued ASU 2014-09 "Revenue from Contract with Customers" as a new Topic, Accounting Standards Codification ("ASC") Topic 606. The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying the new standard, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB ASC. This ASU is effective for annual reporting periods (including interim periods within those periods) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early adoption is not permitted. We are currently evaluating the guidance and have not determined the impact this standard may have on our consolidated financial statements nor decided upon the method of adoption.
	In April 2014, the FASB issued 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" which amends the requirements for reporting discontinued operations. Under ASU 2014-08, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. For public entities, ASU 2014-08 is effective prospectively for fiscal years beginning after December 15, 2014; however, early adoption is permitted, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We adopted the provisions of ASU 2014-08 beginning with the period ended March 31, 2014, and have applied the provisions prospectively.
	Prior to the adoption of ASU 2014-08, the results of operations for operating properties sold or held for sale during the reported periods were shown under Discontinued Operations on the Consolidated Statements of Operations. Beginning with the period ended March 31, 2014, in general, our activity related to individual sales of properties wholly-owned or co-owned with joint ventures will no longer be classified as Discontinued Operations.

Real Estate [Abstract]
Real Estate	Real Estate
	Included in our net real estate are income producing shopping center properties that are recorded at cost less accumulated depreciation and amortization, construction in process and land available for development or sale.
	Land available for development or sale includes real estate projects where vertical construction has yet to commence, but which have been identified by us and are available for future development when market conditions dictate the demand for a new shopping center.  Land available for sale was $21.8 million and $19.9 million at December 31, 2014 and 2013, respectively.
	At December 31, 2014, we had three projects under pre-development.  Our land available for development consisted of:
		Carrying Value As of December 31,
		2014		2013
	Development Project/Location	(In thousands)
	Hartland Towne Square - Hartland Twp., MI	$	4,699	$	25,193
	Lakeland Park Center - Phase II, III - Lakeland, FL	14,506		11,774
	Parkway Shops - Phase II - Jacksonville, FL	7,962		11,673
	Total	$	27,167	$	48,640
	Construction in progress represents existing development and redevelopment projects. When projects are substantially complete and ready for their intended use, balances are transferred to land, buildings or improvements as appropriate.  Construction in progress was $25.7 million and $33.5 million at December 31, 2014 and December 31, 2013, respectively.  The decrease was primarily due to the completion of Phase I of Lakeland Park Center, located in Lakeland, Florida. The cost for Lakeland Park Center Phase I was approximately $33.4 million, excluding initial land costs. This decrease is offset in part by costs associated with the commencement of Phase II of Parkway Shops located in Jacksonville, Florida which commenced in the third quarter of 2014, as well as by costs associated with redevelopment and expansion projects at various centers.

	(2)	In 2014, our decision to market for potential sale certain wholly-owned income producing properties resulted in an impairment provision of $4.6 million. Refer to Note 1 under Accounting for the Impairment of Long-Lived Assets for a discussion of inputs used in determining the fair value of long-lived assets.
	Our impairment provisions for our land available for sale and our income producing properties marketed for potential sale were based upon the difference between the fair value of parcels or properties and our allocated or net book basis of those parcels and properties. Our estimated fair value in these investments are classified as Level 3 of the fair value hierarchy under GAAP.

	Mortgages and unsecured notes payable
	We completed the following financing transactions during 2014:
	•	In May 2014, we completed a $100.0 million private placement of senior unsecured notes consisting of $50.0 million of notes with a ten-year term with a fixed interest rate of 4.65% and $50.0 million of notes with a twelve-year term at a fixed interest rate of 4.74%. A "shelf" facility allows for an additional $50.0 million in notes to the same purchaser within the next three years, subject to approval, pricing and documentation;
	•	Also in May 2014, we closed a $75.0 million senior unsecured term loan with an additional $75.0 million accordion feature. The loan has a seven-year term and bears interest at an annual rate of LIBOR plus 1.25% to 2.25% (initially 1.7%) depending upon our leverage or credit rating. The interest expense is hedged with an existing interest rate swap expiring in April 2016, resulting in an effective fixed initial annual rate of 2.9%. The combined proceeds from the May 2014 financings were used to repay $45.0 million of variable-rate bank term debt due 2017, $75.0 million of bank term debt also due in 2017, the $45.0 million balance on our unsecured revolving line of credit, as well as for general corporate purposes; and
	•	In November 2014, we completed a $100.0 million private placement of senior unsecured notes consisting of $50.0 million of notes with a ten-year term priced at a fixed interest rate of 4.16% and $50.0 million of notes with a twelve-year term priced at a fixed interest rate of 4.3%.
	During 2014 we had the following mortgage transactions:
	•	In conjunction with our acquisition of Bridgewater Falls, we assumed a mortgage loan with a $58.6 million principal balance outstanding and an interest rate of 5.7%. We recorded a premium of approximately $6.8 million based upon the fair value of the loan on the date it was assumed. This mortgage premium is being amortized to interest expense over the remaining life of the loan; and
	•	We repaid mortgages securing the following properties:
	◦	The Auburn Mile mortgage in the amount of $6.6 million with an interest rate of 5.4%; and
	◦	Crossroads Centre mortgage in the amount of $23.2 million with an interest rate of 5.4%.
	Our $354.7 million of fixed rate mortgages have interest rates ranging from 5.0% to 7.4% and are due at various maturity dates from May 2014 through June 2026. The fixed rate mortgage notes are secured by mortgages on properties that have an approximate net book value of $368.7 million as of December 31, 2014.
	We have no mortgage maturities until the second half of 2015 and it is our intent to repay these mortgages using cash, borrowings under our unsecured line of credit, or other sources of financing.
	The mortgage loans encumbering our properties, including properties held by our unconsolidated joint ventures, are generally nonrecourse, subject to certain exceptions for which we would be liable for any resulting losses incurred by the lender.  These exceptions vary from loan to loan but generally include fraud or a material misrepresentation, misstatement or omission by the borrower, intentional or grossly negligent conduct by the borrower that harms the property or results in a loss to the lender, filing of a bankruptcy petition by the borrower, either directly or indirectly and certain environmental liabilities.  In addition, upon the occurrence of certain events, such as fraud or filing of a bankruptcy petition by the borrower, we or our joint ventures would be liable for the entire outstanding balance of the loan, all interest accrued thereon and certain other costs, including penalties and expenses.
	We have entered into mortgage loans which are secured by multiple properties and contain cross-collateralization and cross-default provisions.  Cross-collateralization provisions allow a lender to foreclose on multiple properties in the event that we default under the loan.  Cross-default provisions allow a lender to foreclose on the related property in the event a default is declared under another loan.
	Capital lease
	At December 31, 2014 we had a capital ground lease at our Gaines Marketplace shopping center.  In addition we have a capital lease at our Buttermilk Towne Center with the City of Crescent Springs, Kentucky. Total amounts expensed as interest relating to these leases was $0.2 million, $0.3 million and $0.4 million for each of the years ended December 31, 2014, 2013, and 2012 respectively.

	(2)	Scheduled maturities in 2018 include the $10.0 million balance on the unsecured revolving credit facility drawn as of December 31, 2014.
	Revolving Credit Facility
	In October 2014 we closed an amendment to our Master Loan Agreement which increased our revolving credit facility to $350.0 million (from $240.0 million), extended the maturity to October 2018 and modified interest rates. During 2014 we had net repayments of $17.0 million on our revolving credit facility and had outstanding letters of credit issued under our revolving credit facility, not reflected in the accompanying consolidated balance sheets, totaling $4.1 million. These letters of credit reduce borrowing availability under our bank facility. As of December 31, 2014, $335.9 million was available to be drawn on our $350 million unsecured revolving credit facility subject to certain covenants.
	The revolving credit and term loan facilities contain financial covenants relating to total leverage, fixed charge coverage ratio, tangible net worth and various other calculations.  As of December 31, 2014, we were in compliance with these covenants.
	Junior Subordinated Notes
	Our junior subordinated notes have a variable rate of LIBOR plus 3.30%.  The maturity date is January 2038.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value
	We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.  Derivative instruments (interest rate swaps) are recorded at fair value on a recurring basis. Additionally, we, from time to time, may be required to record other assets at fair value on a nonrecurring basis.  As a basis for considering market participant assumptions in fair value measurements, GAAP establishes three fair value levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value.  The assessed inputs used in determining any fair value measurement could result in incorrect valuations that could be material to our consolidated financial statements. These levels are:
	Level 1	Valuation is based upon quoted prices for identical instruments traded in active markets.
	Level 2	Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.
	Level 3	Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability.
	The following is a description of valuation methodologies used for our assets and liabilities recorded at fair value.
	Derivative Assets and Liabilities
	All of our derivative instruments are interest rate swaps for which quoted market prices are not readily available.  For those derivatives, we measure fair value on a recurring basis using valuation models that use primarily market observable inputs, such as yield curves.  We classify derivative instruments as Level 2.  Refer to Note 12 for additional information on our derivative financial instruments.
	The table below presents the recorded amount of assets and liabilities measured at fair value on a recurring basis as of December 31, 2014 and 2013.
			Balance Sheet location	Total Fair Value			Level 1			Level 2			Level 3

	The carrying values of cash and cash equivalents, restricted cash, receivables and accounts payable and accrued liabilities are reasonable estimates of their fair values because of the short maturity of these financial instruments.
	We estimated the fair value of our debt based on our incremental borrowing rates for similar types of borrowing arrangements with the same remaining maturity and on the discounted estimated future cash payments to be made for other debt.  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).  Since such amounts are estimates that are based on limited available market information for similar transactions, there can be no assurance that the disclosed value of any financial instrument could be realized by immediate settlement of the instrument.  Fixed rate debt (including variable rate debt swapped to fixed through derivatives) with carrying values of $874.7 million and $649.9 million as of December 31, 2014 and 2013, respectively, have fair values of approximately $900.9 million and $650.9 million, respectively.  Variable rate debt’s fair value is estimated to be the carrying values of $38.1 million and $100.1 million as of December 31, 2014 and 2013, respectively. We classify our debt as Level 2.
	Net Real Estate
	Our net real estate, including any identifiable intangible assets, is subject to impairment testing on a nonrecurring basis.  To estimate fair value, we use discounted cash flow models that include assumptions of the discount rates that market participants would use in pricing the asset. To the extent impairment has occurred, we charge to expense the excess of the carrying value of the property over its estimated fair value.  We classify impaired real estate assets as nonrecurring Level 3.
	The table below presents the recorded amount of assets at the time they were marked to fair value during the years ended December 31, 2014 and 2013 on a nonrecurring basis. We did not have any material liabilities that were required to be measured at fair value on a nonrecurring basis during the years ended December 31, 2014 and 2013.

	Equity Investments in Unconsolidated Entities
	Our equity investments in unconsolidated joint venture entities are subject to impairment testing on a nonrecurring basis if a decline in the fair value of the investment below the carrying amount is determined to be a decline that is other-than-temporary.  To estimate the fair value of properties held by unconsolidated entities, we use cash flow models, discount rates, and capitalization rates based upon assumptions of the rates that market participants would use in pricing the asset.  To the extent other-than-temporary impairment has occurred, we charge to expense the excess of the carrying value of the equity investment over its estimated fair value.  We classify other-than-temporarily impaired equity investments in unconsolidated entities as nonrecurring Level 3.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

	We utilize interest rate swap agreements for risk management purposes to reduce the impact of changes in interest rates on our variable rate debt.  On the date we enter into an interest rate swap, the derivative is designated as a hedge against the variability of cash flows that are to be paid in connection with a recognized liability.  Subsequent changes in the fair value of a derivative designated as a cash flow hedge that is determined to be highly effective are recorded in other comprehensive income (“OCI”) until earnings are affected by the variability of cash flows of the hedged transaction. The differential between fixed and variable rates to be paid or received is accrued, as interest rates change, and recognized currently as interest expense in our consolidated statements of operations.  We assess effectiveness of our cash flow hedges both at inception and on an ongoing basis.  Our cash flow hedges become ineffective if critical terms of the hedging instrument and the debt do not perfectly match such as notional amounts, settlement dates, reset dates, calculation period and LIBOR rate.
	At December 31, 2014, we had seven interest rate swap agreements in effect for an aggregate notional amount of $210.0 million that were designated as cash flow hedges.  The agreements provide for swapping one-month LIBOR interest rates ranging from 1.2% to 2.2% on $210.0 million of unsecured term loans, and have expirations ranging from April 2016 to May 2020.

	During 2013, we completed two separate underwritten public offerings of newly issued common shares of beneficial interest, specifically:
	•	On November 13, 2013, we issued 4.5 million shares at $15.90 per share. Our total net proceeds, after deducting expenses, were approximately $70.4 million; and
	•	On March 18, 2013, we issued 8.05 million shares at $15.55 per share.  Our total net proceeds, after deducting expenses, were approximately $122.2 million.
	Controlled equity offerings
	In 2014, through our controlled equity offering we issued 3.8 million common shares, at an average share price of $16.50, and received approximately $61.7 million in net proceeds, after sales commissions and fees of $0.9 million.
	In 2013, we issued 5.4 million common shares through our controlled equity offerings generating approximately $81.7 million in net proceeds, after sales commissions and fees of $1.2 million.  The average share price in 2013 was $15.10 per share.
	Our controlled equity offerings were issued under offerings registered in 2013 whereby we may sell up to 8.0 million common shares of beneficial interest. As of December 31, 2014 we had 4.0 million shares available for issuance.
	We have a dividend reinvestment plan that allows for participating shareholders to have their dividend distributions automatically invested in additional shares of beneficial interest based on the average price of the shares acquired for the distribution.

Share-Based Compensation and Other Benefit Plans	Share-Based Compensation and Other Benefit Plans
	Incentive and Stock Option Plans
	As of December 31, 2014 we have one share-based compensation plan in effect, the 2012 Omnibus Long-Term Incentive Plan (“2012 LTIP”). Under the plan our compensation committee may grant, subject to the Company’s performance conditions as specified by the compensation committee, restricted shares, restricted share units, options and other awards for up to 2 million of our common shares, units or stock options, of which 1.7 million is available for issuance as of December 31, 2014.
	The following share-based compensation plans have been terminated, except with respect to awards outstanding under each plan:
	•	The 2009 Omnibus Long-Term Incentive Plan ("2009 LTIP") which allowed for the grant of restricted shares, restricted share units, options and other awards to trustees, officers and other key employees;
	•	The 2008 Restricted Share Plan for Non-Employee Trustees (the "Trustees' Plan") which allowed for the grant of restricted shares to non-employee trustees of the Company;
	•	2003 LTIP - allowed for the grant of stock options to our executive officers and employees.  As of December 31, 2014, there were 127,248 options exercisable; and
	•	2003 Non-Employee Trustee Stock Option Plan – this plan provided for the annual grant of options to purchase our shares to our non-employee trustees.  As of December 31, 2014, there were 28,000 options exercisable.
	We recognized total share-based compensation expense of $4.6 million, $3.6 million, and $2.6 million for 2014, 2013, and 2012, respectively.
	Restricted Stock Share-Based Compensation
	Beginning in 2012 the compensation committee determined that the LTIP award would consist of 50% service based restricted shares and 50% performance-based cash awards. The service-based restricted share awards include a five year vesting period and the compensation expense is recognized on a graded vesting basis  We recognized expense related to restricted share grants of $2.1 million, $2.1 million and $2.2 million during the years ended December 31, 2014 , 2013, and 2012, respectively.
	The performance shares are earned subject to a future performance measurement based on a three-year shareholder return peer comparison (the “TSR Grants”). If the performance criterion is met the actual value of the grant earned will be determined and 50% of the award will be paid in cash immediately while the balance will be paid in cash the following year.
	Pursuant to ASC 718 – Stock Compensation, we determine the grant date fair value of TSR Grants, and any subsequent re-measurements, based upon a Monte Carlo simulation model.  We recognize the compensation expense ratably over the requisite service period and we are required to re-value the performance cash awards at the end of each quarter. We use the same methodology as was used at the initial grant date and adjust the compensation expense accordingly.  If it is determined that the performance criteria will not be met, compensation expense previously recognized would be reversed.  We recognized compensation expense of $2.5 million, $1.5 million and $0.4 million related to the cash awards during the year ended December 31, 2014, 2013 and 2012, respectively.
	A summary of the activity of service based restricted shares under the LTIP for the years ended December 31, 2014, 2013 and 2012 is presented below:
		2014						2013							2012

	As of December 31, 2014 there was approximately $4.6 million of total unrecognized compensation cost related to non-vested restricted share awards granted under our various share-based plans that we expect to recognize over a weighted average period of 4.2 years.
	Stock Option Share-Based Compensation
	We recognized approximately $0.1 million of expense related to options during the year ended December 31, 2012.  The fair values of each option granted used in determining the share-based compensation expense is estimated on the date of grant using the Black-Scholes option-pricing model.  This model incorporates certain assumptions for inputs including risk-free rates, expected dividend yield of the underlying common shares, expected option life and expected volatility.
	No options were granted under the LTIP in the years ended December 31, 2014, 2013 and 2012.
	The following table reflects the stock option activity for all plans described above:

Income Tax Disclosure [Abstract]
Income Taxes	Taxes
	Income Taxes
	We conduct our operations with the intent of meeting the requirements applicable to a REIT under sections 856 through 860 of the Internal Revenue Code.  In order to maintain our qualification as a REIT, we are required to distribute annually at least 90% of our REIT taxable income, excluding net capital gain, to our shareholders. As long as we qualify as a REIT, we will generally not be liable for federal corporate income taxes.
	Certain of our operations, including property management and asset management, as well as ownership of certain land, are conducted through our TRSs which allows us to provide certain services and conduct certain activities that are not generally considered as qualifying REIT activities.
	Deferred tax assets and liabilities reflect the impact of temporary differences between the amounts of assets and liabilities for financial reporting purposes and the bases of such assets and liabilities as measured by tax laws. Deferred tax assets are reduced by a valuation allowance to the amount where realization is more likely than not assured after considering all available evidence, including expected taxable earnings and potential tax planning strategies. Our temporary differences primarily relate to deferred compensation, depreciation and net operating loss carryforwards.
	As of December 31, 2014, we had a federal and state deferred tax asset of $0.2 million, net of a valuation allowance of $10.9 million.  We believe that it is more likely than not that the results of future operations will generate sufficient taxable income to recognize the net deferred tax assets. These future operations are primarily dependent upon the profitability of our TRSs, the timing and amounts of gains on land sales, and other factors affecting the results of operations of the TRSs.  The valuation allowances relate to net operating loss carryforwards and tax basis differences where there is uncertainty regarding their realizability.
	During the years ended December 31, 2014 and 2013, we recorded an income tax provision of approximately $54,000 and $64,000, respectively.
	We had no unrecognized tax benefits as of or during the three year period ended December 31, 2014.  We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of December 31, 2014.  No material interest or penalties relating to income taxes were recognized in the statement of operations for the years ended December 31, 2014, 2013, and 2012 or in the consolidated balance sheets as of December 31, 2014, 2013, and 2012.  It is our accounting policy to classify interest and penalties relating to unrecognized tax benefits as tax expense.  As of December 31, 2014, returns for the calendar years 2011 through 2014 remain subject to examination by the Internal Revenue Service (“IRS”) and various state and local tax jurisdictions.  As of December 31, 2014, certain returns for calendar year 2010 also remain subject to examination by various state and local tax jurisdictions.
	Sales Tax
	We collect various taxes from tenants and remit these amounts, on a net basis, to the applicable taxing authorities.

	Construction Costs
	In connection with the development and expansion of various shopping centers as of December 31, 2014, we had entered into agreements for construction costs of approximately $10.1 million.
	Litigation
	We are currently involved in certain litigation arising in the ordinary course of business.
	Environmental Matters
	We are subject to numerous federal, state and local environmental laws, ordinances and regulations in the areas where we own or operate properties. We are not aware of any contamination which may have been caused by us or any of our tenants that would have a material effect on our consolidated financial statements.
	As part of our risk management activities, we have applied and been accepted into state sponsored environmental programs which will expedite and assure satisfactory compliance with environmental laws and regulations should contaminants need to be remediated. We also have an environmental insurance policy that covers us against third party liabilities and remediation costs.
	While we believe that we do not have any material exposure to environmental remediation costs, we cannot give absolute assurance that changes in the law or new discoveries of contamination will not result in additional liabilities to us.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Principles of Consolidation and Estimates	Principles of Consolidation and Estimates
	The consolidated financial statements include the accounts of us and our majority owned subsidiary, the Operating Partnership, Ramco-Gershenson Properties, L.P. (97.2%, 96.8% and 95.4% owned by us at December 31, 2014, 2013 and 2012, respectively), and all wholly-owned subsidiaries, including entities in which we have a controlling interest or have been determined to be the primary beneficiary of a variable interest entity (“VIE”).  The presentation of consolidated financial statements does not itself imply that assets of any consolidated entity (including any special-purpose entity formed for a particular project) are available to pay the liabilities of any other consolidated entity, or that the liabilities of any other consolidated entity (including any special-purpose entity formed for a particular project) are obligations of any other consolidated entity.  Investments in real estate joint ventures over which we have the ability to exercise significant influence, but for which we do not have financial or operating control, are accounted for using the equity method of accounting.  Accordingly, our share of the earnings (loss) of these joint ventures is included in consolidated net income (loss).  All intercompany transactions and balances are eliminated in consolidation.
	We own 100% of the non-voting and voting common stock of Ramco-Gershenson, Inc. (“Ramco”), and therefore it is included in the consolidated financial statements.  Ramco has elected to be a taxable REIT subsidiary for federal income tax purposes.  Ramco provides property management services to us and to other entities, including our real estate joint venture partners.
	The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and reported amounts that are not readily apparent from other sources.  Actual results could differ from those estimates.
Reclassifications	Reclassifications
	Certain reclassifications of prior period amounts have been made in the financial statements in order to conform to the 2014 presentation.
Revenue Recognition and Accounts Receivable	Revenue Recognition and Accounts Receivable
	Our shopping center space is generally leased to retail tenants under leases that are classified as operating leases. We recognize minimum rents using the straight-line method over the terms of the leases commencing when the tenant takes possession of the space or when construction of landlord funded improvements is substantially complete. Certain of the leases also provide for contingent percentage rental income which is recorded on an accrual basis once the specified target that triggers this type of income is achieved. The leases also provide for reimbursement from tenants for common area maintenance (“CAM”), insurance, real estate taxes and other operating expenses ("Recovery Income"). The majority of our Recovery Income is estimated and recognized as revenue in the period the recoverable costs are incurred or accrued.  Revenues from management, leasing, and other fees are recognized in the period in which the services have been provided and the earnings process is complete. Lease termination income is recognized when a lease termination agreement is executed by the parties and the tenant vacates the space.  When a lease is terminated early but the tenant continues to control the space under a modified lease agreement, the lease termination fee is generally recognized evenly over the remaining term of the modified lease agreement.
	Current accounts receivable from tenants primarily relate to contractual minimum rent, percentage rent and Recovery Income.
	We provide for bad debt expense based upon the allowance method of accounting. We monitor the collectability of our accounts receivable from specific tenants on an ongoing basis, analyze historical bad debts, customer creditworthiness, current economic trends and changes in tenant payment terms when evaluating the adequacy of the allowance for bad debts.  Allowances are taken for those balances that we have reason to believe may be uncollectible.  When tenants are in bankruptcy, we make estimates of the expected recovery of pre-petition and post-petition claims.  The period to resolve these claims can exceed one year.  Management believes the allowance for doubtful accounts is adequate to absorb currently estimated bad debts.  However, if we experience bad debts in excess of the allowance we have established, our operating income would be reduced.  At December 31, 2014 and 2013, our accounts receivable were $12.0 million and $9.6 million, respectively, net of allowances for doubtful accounts of $2.3 million and $2.4 million, respectively.
	In addition, many of our leases contain non-contingent rent escalations for which we recognize income on a straight-line basis over the non-cancelable lease term.  This method results in rental income in the early years of a lease being higher than actual cash received, creating a straight-line rent receivable asset which is included in the “Other assets, net” line item in our consolidated balance sheets.  We review our unbilled straight-line rent receivable balance to determine the future collectability of revenue that will not be billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors.  Our evaluation is based on our assessment of tenant credit risk changes indicating that expected future straight-line rent may not be realized.  Depending on circumstances, we may provide a reserve against the previously recognized straight-line rent receivable asset for a portion, up to its full value, that we estimate may not be received.  The balance of straight-line rent receivable at December 31, 2014 and 2013, net of allowances was $15.8 million and $15.1 million, respectively.  To the extent any of the tenants under these leases become unable to pay their contractual cash rents, we may be required to write down the straight-line rent receivable from those tenants, which would reduce our operating income.
Real Estate	Real Estate
	Real estate assets that we own directly are stated at cost less accumulated depreciation.  Depreciation is computed using the straight-line method.  The estimated useful lives for computing depreciation are generally 10 – 40 years for buildings and and improvements and 5 – 30 years for parking lot surfacing and equipment.  We capitalize all capital improvement expenditures associated with replacements and improvements to real property that extend its useful life and depreciate them over their estimated useful lives ranging from 15 – 25 years.  In addition, we capitalize qualifying tenant leasehold improvements and depreciate them over the useful life of the improvements or the term of the related tenant lease.  We also capitalize direct internal and external costs of procuring leases and amortize them over the base term of the lease.  If a tenant vacates before the expiration of its lease, we charge unamortized leasing costs and undepreciated tenant leasehold improvements of no future value to expense.  We charge maintenance and repair costs that do not extend an asset’s life to expense as incurred.
	Sale of a real estate asset is recognized when it is determined that the sale has been consummated, the buyer’s initial and continuing investment is adequate, our receivable, if any, is not subject to future subordination, and the buyer has assumed the usual risks and rewards of ownership of the asset. We will classify properties as held for sale when executed purchase and sales agreement contingencies have been satisfied thereby signifying that the sale is guaranteed and legally binding.
	We allocate the costs of acquisitions to assets acquired and liabilities assumed based on estimated fair values, replacement costs and appraised values.  The purchase price of the acquired property is allocated to land, building, improvements and identifiable intangibles such as in-place leases, above/below market leases, out-of-market assumed mortgages, and gain on purchase, if any.  The value allocated to above/below market leases is amortized over the related lease term and included in rental income in our consolidated statements of operations. Should a tenant terminate its lease prior to its stated expiration, all unamortized amounts relating to that lease would be written off.
	Real estate also includes costs incurred in the development of new operating properties and the redevelopment of existing operating properties.  These properties are carried at cost and no depreciation is recorded on these assets until the commencement of rental revenue or no later than one year from the completion of major construction.  These costs include pre-development costs directly identifiable with the specific project, development and construction costs, interest, real estate taxes and insurance.  Interest is capitalized on land under development and buildings under construction based on the weighted average rate applicable to our borrowings outstanding during the period and the weighted average balance of qualified assets under development/redevelopment during the period.  Indirect project costs associated with development or construction of a real estate project are capitalized until the earlier of one year following substantial completion of construction or when the property becomes available for occupancy.
	The capitalized costs associated with development and redevelopment projects are depreciated over the useful life of the improvements.  If we determine a development or redevelopment project is no longer probable, we expense all capitalized costs which are not recoverable.
	It is our policy to start vertical construction on new development projects only after the project has received entitlements, significant anchor leasing commitments, construction financing and joint venture partner commitments, if appropriate.  We are in the entitlement and pre-leasing phases at our development projects.
Accounting for the Impairment of Long-Lived Assets	Accounting for the Impairment of Long-Lived Assets
	We review our investment in real estate, including any related intangible assets, for impairment on a property-by-property basis whenever events or changes in circumstances indicate that the carrying value of the property may not be recoverable.  These changes in circumstances include, but are not limited to, changes in occupancy, rental rates, tenant sales, net operating income, real estate values and expected holding period.  The viability of all projects under construction or development, including those owned by unconsolidated joint ventures, are regularly evaluated under applicable accounting requirements, including requirements relating to abandonment of assets or changes in use.  To the extent a project, or individual components of the project, are no longer considered to have value, the related capitalized costs are charged against operations.
	Impairment provisions resulting from any event or change in circumstances, including changes in management’s intentions or management’s analysis of varying scenarios, could be material to our consolidated financial statements.
	We recognize an impairment of an investment in real estate when the estimated undiscounted cash flow is less than the net carrying value of the property.  If it is determined that an investment in real estate is impaired, then the carrying value is reduced to the estimated fair value as determined by cash flow models and discount rates or comparable sales in accordance with our fair value measurement policy. Refer to Note 6 of the notes to the consolidated financial statements for further information.
	In 2014, we recorded impairment provisions totaling $27.9 million consisting of:
	•	$23.3 million related to certain parcels of land available for development or sale due to changes in plans or in fair value estimates; and
	•	$4.6 million of related to income producing properties that we have identified to be marketed for sale.
Investments in Real Estate Joint Ventures	Investments in Real Estate Joint Ventures
	We have four equity investments in unconsolidated joint venture entities in which we own 30% or less of the total ownership interest.  Because we can influence but not make significant decisions without our partners' approval, these investments are accounted for under the equity method of accounting. We provide leasing, development, asset and property management services to these joint ventures for which we are paid fees.  Refer to Note 7 of the notes to the consolidated financial statements for further information.
	We review our equity investments in unconsolidated entities for impairment on a venture-by-venture basis whenever events or changes in circumstances indicate that the carrying value of the equity investment may not be recoverable. In testing for impairment of these equity investments, we primarily use cash flow models, discount rates, and capitalization rates to estimate the fair value of properties held in joint ventures, and mark the debt of the joint ventures to market.  Considerable judgment by management is applied when determining whether an equity investment in an unconsolidated entity is impaired and, if so, the amount of the impairment. Changes to assumptions regarding cash flows, discount rates, or capitalization rates could be material to our consolidated financial statements.
	There were no impairment provisions on our equity investments in joint ventures recorded in 2014.
Other Assets, net	Other Assets, net
	Other assets consist primarily of acquired lease intangibles, straight-line rent receivable, deferred leasing costs, deferred financing costs and prepaid expenses. Other assets also include the the fair value of in-place public improvement fee income and real estate tax exemption agreements associated with two properties acquired in 2014. Deferred financing and leasing costs are amortized using the straight-line method over the terms of the respective agreements. Should a tenant terminate its lease, the unamortized portion of the leasing cost is expensed.  Unamortized financing costs are expensed when the related agreements are terminated before their scheduled maturity dates.  We review our unbilled straight-line rent receivable balance to determine the future collectability of revenue that will not be billed to or collected from tenants due to early lease terminations, lease modifications, bankruptcies and other factors.  Our evaluation is based on our assessment of tenant credit risk changes indicating that expected future straight-line rent may not be realized.  Depending on circumstances, we may provide a reserve against the previously recognized straight-line rent receivable asset for a portion, up to its full value, that we estimate may not be received.
Cash and Cash Equivalents	Cash and Cash Equivalents
	We consider all highly liquid investments with an original maturity of three months or less to be cash equivalents.  Cash balances in individual banks may exceed the federally insured limit by the Federal Deposit Insurance Corporation (the “FDIC”).  As of December 31, 2014, we had $12.7 million in excess of the FDIC insured limit.
Recognition of Share-based Compensation Expense	Recognition of Share-based Compensation Expense
	We grant share-based compensation awards to employees and trustees in the form of restricted common shares and in the past we have granted stock options to employees and trustees.  Our share-based award costs are equal to each grant date fair value and are recognized over the service periods of the awards using the graded vesting method.  See Note 16 of the notes to the consolidated financial statements for further information.
Income Tax Status	Income Tax Status
	We made an election to qualify, and believe our operating activities permit us to qualify as a REIT for federal income tax purposes.  Accordingly, we generally will not be subject to federal income tax, provided that we distribute at least 90% of our taxable income annually to our shareholders and meet other conditions.  We are obligated to pay state taxes, generally consisting of franchise or gross receipts taxes in certain states which are not material to our consolidated financial statements.
	Certain of our operations, including property and asset management, as well as ownership of certain land parcels, are conducted through taxable REIT subsidiaries, (“TRSs”) which are subject to federal and state income taxes.  During the years ended December 31, 2014, 2013, and 2012, we sold various properties and land parcels at a gain, resulting in both a federal and state tax liability.  See Note 17 of the notes to the consolidated financial statements for further information.
Variable Interest Entities	Variable Interest Entities
	Certain entities that do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties or in which equity investors do not have the characteristics of a controlling financial interest qualify as VIEs.  VIEs are required to be consolidated by their primary beneficiary.  The primary beneficiary of a VIE has both (i) the power to direct the activities that most significantly impact economic performance of the VIE, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE.
	We have evaluated our investments in joint ventures and determined that the joint ventures do not meet the requirements of a VIE and, therefore, consolidation of these ventures is not required.  Accordingly, these investments are accounted for using the equity method.
Noncontrolling Interest in Subsidiaries	Noncontrolling Interest in Subsidiaries
	There are third parties who have certain noncontrolling interests in subsidiaries that are exchangeable for our common shares on a 1:1 basis or cash, at our election.   Noncontrolling interest is classified as a separate component of equity outside of the permanent equity section of our consolidated balance sheets.  Consolidated net income and comprehensive income includes the noncontrolling interest’s share.  The calculation of earnings per share is based on income available to common shareholders.
Segment Information	Segment Information
	Our primary business is the ownership, management, redevelopment, development and operation of retail shopping centers.  We do not distinguish our primary business or group our operations on a geographical basis for purposes of measuring performance.  We review operating and financial data for each property on an individual basis and define an operating segment as an individual property.  The individual properties have been aggregated into one reportable segment based upon their similarities with regard to both the nature and economics of the centers, tenants and operational processes, as well as long-term financial performance.  No one individual property constitutes more than 10% of our revenue or property operating income and none of our shopping centers are located outside the United States.   Accordingly, we have a single reportable segment for disclosure purposes.
