Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies RPT Realty, together with our subsidiaries (the “Company”), is a real estate investment trust (“REIT”) engaged in the business of owning and operating a national portfolio of dynamic open-air shopping destinations principally located in the top U.S. markets. The Company's locally-curated consumer experience reflect the lifestyles of its diverse neighborhoods and match the modern expectation of its retail partners. As of December 31, 2018 , the Company's portfolio consisted of 51 shopping centers (including one shopping center owned through a joint venture) representing 12.4 million square feet. We also have ownership interests of 7% , 20% , and 30% , respectively, in three joint ventures, one of which owns a single shopping center and two with no significant activity. Our joint ventures are reported using equity method accounting. We earn fees from certain joint ventures for managing, leasing and redeveloping the shopping centers they own. We also own interests in several land parcels that are available for development. Most of our properties are anchored by supermarkets and/or national chain stores. The Company's credit risk, therefore, is concentrated in the retail industry. As of December 31, 2018 , our wholly-owned properties located in Michigan and Florida accounted for approximately 19% , and 23% , respectively, of our annualized base rent. 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 The consolidated financial statements include the accounts of us and our majority owned subsidiary, the Operating Partnership, RPT Realty, L.P. ( 97.7% , 97.7% and 97.6% owned by us at December 31, 2018 , 2017 and 2016 , 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 RPT Realty, Inc., and therefore it is included in the consolidated financial statements. RPT Realty, Inc. has elected to be a taxable REIT subsidiary for federal income tax purposes. RPT Realty, Inc. provides property management services to us and to other entities, including certain real estate joint venture partners. Use of Estimates 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 consolidated financial statements and footnotes in order to conform to the current 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, 2018 and 2017 , our accounts receivable were $23.8 million and $26.1 million , respectively, net of allowances for doubtful accounts of $0.9 million and $1.4 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, 2018 and 2017 , net of allowances of $2.3 million and $2.7 million was $21.2 million and $19.4 million , respectively. To the extent any of the tenants under these leases become unable to pay its contractual cash rents, we may be required to write down the straight-line rent receivable from that tenant, 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 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 the property's 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 lesser of 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 legally binding. Acquisitions of properties are accounted for utilizing the acquisition method and, accordingly, the results of operations of an acquired property are included in our results of operations from the date of acquisition. Estimates of fair values are based upon future cash flows and other valuation techniques in accordance with our fair value measurements policy, which are used to allocate the purchase price of acquired property among land, buildings on an “as if vacant” basis, tenant improvements, identifiable intangibles and any gain on purchase. Identifiable intangible assets and liabilities include the effect of above-and below-market leases, the value of having leases in place (“as-is” versus “as if vacant” and absorption costs), other intangible assets such as assumed tax increment revenue bonds and out-of-market assumed mortgages. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of 40 years for buildings, and over the remaining terms of any intangible asset contracts and the respective tenant leases, which may include bargain renewal options. The impact of these estimates, including estimates in connection with acquisition values and estimated useful lives, could result in significant differences related to the purchased assets, liabilities and subsequent depreciation or amortization expense. 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, is 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, is 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. In 2018 , we recorded impairment provisions totaling $0.2 million and $13.4 million , related to developable land and shopping centers classified as income producing, respectively. The adjustment related to land was triggered by higher costs related to this parcel. The impairment provision on income producing properties was related to the Company's decision to market for potential sale certain wholly-owned income producing properties. Investments in Real Estate Joint Ventures We have three equity investments in unconsolidated joint venture entities in which we own 30% or less of the total ownership interest. Under three of the joint ventures, 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. 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 2018 , 2017 or 2016 . Deferred Financing Costs Debt issuance costs related to a recognized debt liability is presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Unamortized debt issuance costs of $3.1 million and $3.8 million are included in Notes payable, net as of December 31, 2018 and 2017 , respectively. Debt issuance costs associated with a line of credit arrangement is classified as an asset and subsequently amortized ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. Unamortized debt issuance costs related to our unsecured revolving credit facility of $2.0 million and $2.7 million are included in Other assets, net as of December 31, 2018 and 2017 , respectively. Other Assets, net Other assets consist primarily of acquired development agreement intangibles, an acquired ground lease intangible, straight-line rent receivable, deferred leasing costs, deferred financing costs related to our unsecured revolving credit facility and prepaid expenses. Deferred financing costs related to our unsecured revolving credit facility and leasing costs are amortized using the straight-line method over the terms of the respective agreements, which approximates the effective interest method. Should a tenant terminate its lease, the unamortized portion of the leasing cost is expensed. Unamortized deferred financing costs are expensed when the related agreements are terminated before their scheduled maturity dates. Lastly, the acquired development agreement and acquired ground lease intangible assets are amortized over the terms of the respective agreements as well. 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, 2018 , we had $39.3 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 cash settled awards, 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. We recognize forfeitures related to stock awards and stock options as they occur. See Note 15 of the notes to the consolidated financial statements for further information regarding our share based compensation. Income Tax Status We made an election, 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, 2018 , 2017 , and 2016 , we sold various properties and land parcels at a gain, resulting in both a federal and state tax liability. See Note 16 of the notes to the consolidated financial statements for further information regarding income taxes. 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 our joint ventures do not meet the requirements of a VIE and, therefore, consolidation of these ventures is not required. Noncontrolling Interest in Subsidiaries There are third parties who have certain noncontrolling interests in the Operating Partnership 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 is located outside the United States. Accordingly, we have a single reportable segment for disclosure purposes.

Accounting Changes and Error Corrections [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2017, the FASB issued ASU 2017-05 "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" ("ASU 2017-05"). ASU 2017-05 clarifies that a financial asset is within the scope of Subtopic 610-20 if it meets the definition of an in substance nonfinancial asset. ASU 2017-05 also defines the term "in substance nonfinancial asset". In addition, ASU 2017-05 eliminates the guidance specific to real estate sales in ASC 360-20. It became effective for annual periods beginning after December 15, 2017, therefore we adopted the standard on January 1, 2018. In doing so, the Company recorded an adjustment under the modified retrospective method of approximately $2.2 million to shareholders' equity associated with a transaction that occurred in the fourth quarter of 2017. The adjustment had no impact on earnings or cash flows. In May 2017, the FASB issued ASU 2017-09 "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting" ("ASU 2017-09"). ASU 2017-09 clarifies guidance about what changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. It became effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18 "Statement of Cash Flows." This new guidance became effective January 1, 2018, with early adoption permitted, and requires amounts that are generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement requires a retrospective transition method of adoption. The adoption of this standard resulted in the reclassification of approximately $ 4.0 million of cash outflows from real estate acquisitions during the year ended December 31, 2017 and approximately $4.0 million of cash outflows from development and capital improvements during the year ended December 31, 2016 that were held in escrow as restricted cash. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balances sheets that reconciles to the total shown within the consolidated statements of cash flows. As of December 31, 2018 2017 2016 (In thousands) Cash and cash equivalents $ 41,064 $ 8,081 $ 3,582 Restricted cash and escrows 3,658 4,810 11,144 $ 44,722 $ 12,891 $ 14,726 Restricted cash generally consists of funds held in escrow by lenders to pay real estate taxes, insurance premiums and certain capital expenditures. In limited instances, restricted cash may include deposits on potential future acquisitions and/or proceeds related to dispositions of real estate. In August 2016, the FASB issued ASU 2016-15 "Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"), which clarifies the treatment of several cash flow categories. In addition, ASU 2016-15 clarifies that when cash receipts and cash payments have aspects of more than one class of cash flows and cannot be separated, classification will depend on the predominant source or use. This update became effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted, including adoption in an interim period. The adoption of this standard did not have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). ASU 2014-09 is a comprehensive revenue recognition standard that superseded nearly all prior GAAP revenue recognition guidance as well as prior GAAP guidance governing the sale of non-financial assets. The standard’s core principle is that a company should recognize revenue when it satisfies performance obligations, by transferring promised goods or services to customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for fulfilling those performance obligations. In doing so, companies need to exercise more judgment and make more estimates than under prior GAAP guidance. ASU 2014-09 became effective for public entities for annual and interim reporting periods beginning after December 15, 2017 and early adoption was permitted in periods ending after December 15, 2016. The guidance permitted two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect initially applying the guidance recognized at the date of initial application (modified retrospective method). We adopted the standard and the related updates subsequently issued by the FASB using the modified retrospective method on January 1, 2018. ASU 2014-09 applies only to certain revenue included in Other Property Income and Management and Other Fee Income in our Consolidated Statement of Operations which approximate $4.1 million or less than 2.0% of total revenue. The timing of revenue recognition associated with these items remains substantially unchanged and no adjustment occurred upon adoption. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-13, "Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement", which amends ASC 820, Fair Value Measurement. ASU 2018-13 modified the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. This standard is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We are currently evaluating the guidance and have not determined the impact this standard may have on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting", which expands the scope of Topic 718, Compensation-Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. This standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU 2018-07 is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04 "Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our consolidated financial statements. In June 2016, the FASB updated Accounting Standards Codification ("ASC") Topic 326 "Financial Instruments - Credit Losses" with ASU 2016-13 “Measurement of Credit Losses on Financial Instruments” ("ASU 2016-13"). ASU 2016-13 enhances the methodology of measuring expected credit losses to include the use of forward-looking information to better inform credit loss estimates. In November 2018, the FASB subsequently issued ASU 2018-19, which clarifies that receivables arising from operating leases are not within the scope of the credit losses standard, but rather, should be accounted for in accordance with the leases standard. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within that fiscal year. We are currently evaluating the guidance and have not determined the impact this standard may have on our consolidated financial statements. In February 2016, the FASB updated ASC Topic 842 "Leases" ("ASU 2016-02"). ASU 2016-02 requires lessees to record operating and financing leases as assets and liabilities on the balance sheet and lessors to expense costs that are not direct leasing costs. In addition, the following ASUs were subsequently issued related to ASC Topic 842, all of which will be effective with ASU 2016-02: • In January 2018, the FASB issued ASU 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842". The standard provides an optional transition practical expedient for the adoption of ASU 2016-02 that, if elected, would not require an organization to reconsider its accounting for existing land easements that are not currently accounted for under the old leases standard. • In July 2018, the FASB issued ASU 2018-10, "Codification Improvements to Topic 842, Leases", which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02. • In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842): Targeted Improvements", which provide lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance (Topic 606) and certain criteria are met. The guidance also provides an optional transition method which would allow entities to initially apply the new guidance in the period of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings, if necessary. • In December 2018, the FASB issued ASU 2018-20, "Leases (Topic 842): Narrow-Scope Improvements for Lessors", which addresses specific issues in the leasing guidance, including sales taxes and other similar taxes collected from lessees, certain lessor costs paid directly by lessees, and recognition of variable payments for contracts with leases and nonlease components. ASU 2016-02 is effective for periods beginning after December 15, 2018, with early adoption permitted using a modified retrospective approach. The Company has elected the practical expedients allowable under ASU 2018-01 and ASU 2018-11, and has concluded the adoption of ASU 2016-02 will not have a material impact for operating leases where we are a lessor and we will continue to record revenues from rental properties for operating leases on a straight-line basis. In addition, for leases where the Company is a lessee, primarily the Company’s ground lease and administrative office leases, the Company will record a lease liability of $16.6 million and a right of use asset of $18.0 million upon adoption related to these items. Additionally, only incremental direct leasing costs will be capitalized under this new guidance and expect to recognize a cumulative effect adjustment to accumulated distributions in excess of net income of primarily relating to certain costs associated with unexecuted leases that were deferred of $0.4 million as of December 31, 2018 . The Company has adopted this new guidance effective on January 1, 2019.

The adjustment was triggered by changes in the associated market prices and expected hold period assumptions related to these shopping centers. During 2018, we recorded an impairment provision totaling $0.2 million on a land parcel due to higher costs related to this parcel. During 2017, the Company's decision to market for potential sale certain wholly-owned income producing properties resulted in an impairment provision of $ 8.4 million . The adjustment was triggered by changes in the associated market prices and expected hold period assumptions related to these shopping centers. During 2017, changes in the expected use and changes in associated sales price assumptions related to land held for development or sale resulted in an impairment provision of $1.0 million . During 2016, unforeseen increases in development costs, changes in associated sales price assumptions and a change in the expected use of the land held for development resulted in impairment provisions of $1.0 million .

Equity Method Investments and Joint Ventures [Abstract]
Equity Investments in Unconsolidated Joint Ventures	Equity Investments in Unconsolidated Joint Ventures We have three joint venture agreements whereby we own 7% , 20% and 30% , respectively, of the equity in each joint venture. We and the joint venture partners have joint approval rights for major decisions, including those regarding property operations. We cannot make significant decisions without our partner’s approval. Accordingly, we account for our interest in the joint ventures using the equity method. On April 27, 2018 we sold our 30% interest in a joint venture created in November 2017 for proceeds of $3.1 million to our unrelated joint venture partner. The proceeds received from the transaction represent the return of our initial investment of $3.0 million and our share of earnings from the joint venture's operations since inception of $0.1 million . We did not record a gain or loss on sale of our interest in the joint venture.

The mortgage loans encumbering our properties 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.

Fair Value

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 11 of notes to the consolidated financial statements 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, 2018 and 2017 . Balance Sheet Location Total Fair Value Level 1 Level 2 Level 3 2018 (In thousands) Derivative assets - interest rate swaps Other assets $ 4,115 $ — $ 4,115 $ — Derivative liabilities - interest rate swaps Other liabilities $ — $ — $ — $ — 2017 Derivative assets - interest rate swaps Other assets $ 3,133 $ — $ 3,133 $ — Derivative liabilities - interest rate swaps Other liabilities $ (208 ) $ — $ (208 ) $ — Other Assets and Liabilities 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. Debt 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 $935.1 million and $940.9 million as of December 31, 2018 and 2017 , respectively, have fair values of approximately $928.2 million and $940.8 million , respectively. Variable rate debt’s fair value is estimated to be the carrying values of $28.1 million and $58.1 million as of December 31, 2018 and 2017 , respectively. We classify our debt as Level 2. Net Real Estate Our net real estate, including any identifiable intangible assets, are regularly subject to impairment testing but marked to fair value 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, 2018 and 2017 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, 2018 and 2017 .

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]
Derivative Financial Instruments	Derivative Financial Instruments We utilize interest rate swap agreements for risk management purposes to reduce the impact of changes in interest rates on our variable rate debt. We may also enter into forward starting swaps to set the effective interest rate on planned variable rate financing. 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, 2018 , all of our hedges were highly effective. As of December 31, 2018 , we had seven interest rate swap agreements in effect for an aggregate notional amount of $210.0 million converting our floating rate corporate debt to fixed rate debt. All of our interest rate swap agreements are designated as cash flow hedges. The agreements provide for swapping one-month LIBOR interest rates ranging from 1.460% to 2.150% and have expirations ranging from May 2020 to March 2023 .

Share-Based Compensation and Other Benefit Plans	Share-Based Compensation and Other Benefit Plans Incentive, Inducement and Stock Option Plans As of December 31, 2018 we had two share-based compensation plan in effect: 1) the 2012 Omnibus Long-Term Incentive Plan (“2012 LTIP”) under which our compensation committee may grant, subject to any Company performance conditions as specified by the compensation committee, restricted shares, restricted share units, options and other awards to trustees, officers and other key employees; and 2) the Inducement Incentive Plan (“Inducement Plan”), which was approved by the Board of Trustees in April 2018 and under which our compensation committee may grant, subject to any Company performance conditions as specified by the compensation committee, restricted shares, restricted share units, options and other awards to individuals who were not previously employees or members of the Board as an inducement material to the individual’s entry into employment with the Company. The 2012 LTIP allows us to issue up to 2.0 million common shares of beneficial interest, of which 0.9 million remained available for issuance as of December 31, 2018 . The Inducement Plan allows us to issue up to 6.0 million common shares of beneficial interest, of which 5.4 million remained available for issuance as of December 31, 2018 . 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; and • 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; We recognized total share-based compensation expense of $6.7 million , $4.4 million , and $3.5 million for 2018 , 2017 , and 2016 , respectively. Restricted Stock Share-Based Compensation Under the 2012 LTIP and Inducement Plan, the Company has made grants of service-based restricted shares, performance-based cash awards and performance-based equity awards. The service-based restricted share awards to employees vest over three years or five years and the compensation expense is recognized on a graded vesting basis. The service-based restricted share awards to trustees vest over one year . We recognized expense related to service-based restricted share grants of $4.7 million for the year ended December 31, 2018 , $2.7 million for year ended December 31, 2017 and $2.9 million for the year ended December 31, 2016 . A summary of the activity of service-based restricted shares under the 2012 LTIP and Inducement Plan for the years ended December 31, 2018 , 2017 and 2016 is presented below: 2018 2017 2016 Number of Shares Weighted- Average Grant Date Fair Value Number of Shares Weighted- Average Grant Date Fair Value Number of Shares Weighted- Average Grant Date Fair Value Outstanding, beginning of the year 412,195 $ 15.58 327,543 $ 17.02 327,732 $ 16.39 Granted 492,871 12.99 210,895 14.22 130,890 17.80 Vested (478,863 ) 13.57 (119,134 ) 16.66 (124,187 ) 15.88 Forfeited or expired (72,174 ) 13.96 (7,109 ) 14.75 (6,892 ) 16.76 Outstanding, end of the year 354,029 $ 13.05 412,195 $ 15.58 327,543 $ 17.02 The performance-based awards are earned subject to a future performance measurement based on a three -year shareholder return peer comparison (the “TSR Grants”). Pursuant to ASC 718 – Stock Compensation, we determine the grant date fair value of TSR Grants that will be settled in cash, and any subsequent re-measurements, based upon a Monte Carlo simulation model. We will recognize the compensation expense ratably over the requisite service period. We are required to re-value the cash awards at the end of each quarter using the same methodology as was used at the initial grant date and adjust the compensation expense accordingly. If at the end of the three -year measurement period the performance criterion is not met, compensation expense related to the cash awards previously recognized would be reversed. We recognized compensation expense of $0.9 million , $1.5 million and $0.7 million related to these performance awards recorded during the years ended December 31, 2018 , 2017 and 2016 , respectively. The Company also determines the grant date fair value of the TSR Grants that will be settled in equity based upon a Monte Carlo simulation model and recognizes the compensation expense ratably over the requisite service period. These equity awards are not re-valued at the end of each quarter. The compensation cost will be recognized regardless of whether the performance criterion are met, provided the requisite service has been provided. We recognized compensation expense of $1.1 million and $0.2 million related to these performance awards recorded during the years ended December 31, 2018 and 2017 , respectively. As of December 31, 2018 , we had $6.9 million of total unrecognized compensation expense related to unvested restricted shares and performance based equity and cash awards. This expense is expected to be recognized over a weighted-average period of 2.3 years. Stock Option Share-Based Compensation When we grant options, the fair value 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, 2018 , 2017 and 2016 . The following table reflects the stock option activity for all plans described above: 2018 2017 2016 Shares Under Option Weighted-Average Exercise Price Shares Under Option Weighted-Average Exercise Price Shares Under Option Weighted-Average Exercise Price Outstanding, beginning of the year — $ — 57,140 $ 34.69 107,165 $ 32.13 Granted — — — — — — Exercised — — — — — — Forfeited or expired — — (57,140 ) 34.69 (50,025 ) 29.21 Outstanding, end of the year — $ — — $ — 57,140 $ 34.69 Exercisable, end of the year — $ — — $ — 57,140 $ 34.69 Other Benefit Plan The Company has a defined contribution profit sharing plan and trust (the "Plan") with a qualified cash or deferred 401(k) arrangement covering all employees. Participation in the Plan is discretionary for all full-time employees who have attained the age of 21. The entry date eligibility is the first pay date of a quarter following the date of hire. Our expense for the years ended December 31, 2018 , 2017 and 2016 was approximately $0.2 million , $0.2 million and $0.2 million , respectively.

Income Tax Disclosure [Abstract]
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, impairment charges and net operating loss carryforwards. As of December 31, 2018 , we had a federal and state deferred tax asset of $7.4 million and a valuation allowance of $7.4 million , which represents a increase of $0.7 million from December 31, 2017 . Our deferred tax assets, such as net operating losses and land basis differences, are reduced by an offsetting valuation allowance where there is uncertainty regarding their realizability. We believe that it is more likely than not that the results of future operations will not generate sufficient taxable income to recognize the 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. If in the future we are able to conclude it is more likely than not that we will realize a future benefit from a deferred tax asset, we will reduce the related valuation allowance by the appropriate amount. If this occurs, it will result in a net deferred tax asset on our balance sheet and an income tax benefit of equal magnitude in our statement of operations in the period we made the determination. During the years ended December 31, 2018 , 2017 and 2016 , we recorded an income tax provision of approximately $0.2 million , $0.1 million , and $0.3 million , respectively. We had no unrecognized tax benefits as of or during the three year period ended December 31, 2018 . We expect no significant increases or decreases in unrecognized tax benefits due to changes in tax positions within one year of December 31, 2018 . No material interest or penalties relating to income taxes were recognized in the statement of operations for the years ended December 31, 2018 , 2017 , and 2016 or in the consolidated balance sheets as of December 31, 2018 , 2017 , and 2016 . It is our accounting policy to classify interest and penalties relating to unrecognized tax benefits as tax expense. As of December 31, 2018 , returns for the calendar years 2015 through 2018 remain subject to examination by the Internal Revenue Service (“IRS”) and various state and local tax jurisdictions. As of December 31, 2018 , certain returns for calendar year 2014 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.

Guarantee A redevelopment agreement was entered into between the City of Jacksonville, the Jacksonville Economic Development Commission and the Company, to construct and develop River City Marketplace in 2005. As part of the agreement, the city agreed to finance up to $12.2 million of bonds. Repayment of the bonds is to be made in accordance with a level-payment amortization schedule over 20 years, and repayments are made out of tax revenues generated by the redevelopment. The remaining debt service payments due over the life of the bonds, including principal and interest, are $10.3 million . As part of the redevelopment, the Company executed a guaranty agreement whereby the Company would fund debt service payments if incremental revenues were not sufficient to fund repayment. There have been no payments made by the Company under this guaranty agreement to date. 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.

Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of us and our majority owned subsidiary, the Operating Partnership, RPT Realty, L.P. ( 97.7% , 97.7% and 97.6% owned by us at December 31, 2018 , 2017 and 2016 , 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 RPT Realty, Inc., and therefore it is included in the consolidated financial statements. RPT Realty, Inc. has elected to be a taxable REIT subsidiary for federal income tax purposes. RPT Realty, Inc. provides property management services to us and to other entities, including certain real estate joint venture partners.
Use of Estimates	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 consolidated financial statements and footnotes in order to conform to the current 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, 2018 and 2017 , our accounts receivable were $23.8 million and $26.1 million , respectively, net of allowances for doubtful accounts of $0.9 million and $1.4 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, 2018 and 2017 , net of allowances of $2.3 million and $2.7 million was $21.2 million and $19.4 million , respectively. To the extent any of the tenants under these leases become unable to pay its contractual cash rents, we may be required to write down the straight-line rent receivable from that tenant, 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 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 the property's 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 lesser of 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 legally binding. Acquisitions of properties are accounted for utilizing the acquisition method and, accordingly, the results of operations of an acquired property are included in our results of operations from the date of acquisition. Estimates of fair values are based upon future cash flows and other valuation techniques in accordance with our fair value measurements policy, which are used to allocate the purchase price of acquired property among land, buildings on an “as if vacant” basis, tenant improvements, identifiable intangibles and any gain on purchase. Identifiable intangible assets and liabilities include the effect of above-and below-market leases, the value of having leases in place (“as-is” versus “as if vacant” and absorption costs), other intangible assets such as assumed tax increment revenue bonds and out-of-market assumed mortgages. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of 40 years for buildings, and over the remaining terms of any intangible asset contracts and the respective tenant leases, which may include bargain renewal options. The impact of these estimates, including estimates in connection with acquisition values and estimated useful lives, could result in significant differences related to the purchased assets, liabilities and subsequent depreciation or amortization expense. 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, is 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, is 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.
Investments in Real Estate Joint Ventures	We have three equity investments in unconsolidated joint venture entities in which we own 30% or less of the total ownership interest. Under three of the joint ventures, 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. 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.
Deferred Financing Costs	Debt issuance costs related to a recognized debt liability is presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Unamortized debt issuance costs of $3.1 million and $3.8 million are included in Notes payable, net as of December 31, 2018 and 2017 , respectively. Debt issuance costs associated with a line of credit arrangement is classified as an asset and subsequently amortized ratably over the term of the line of credit arrangement, regardless of whether there are any outstanding borrowings on the line of credit arrangement. Unamortized debt issuance costs related to our unsecured revolving credit facility of $2.0 million and $2.7 million are included in Other assets, net as of December 31, 2018 and 2017 , respectively.
Other Assets, net	Other assets consist primarily of acquired development agreement intangibles, an acquired ground lease intangible, straight-line rent receivable, deferred leasing costs, deferred financing costs related to our unsecured revolving credit facility and prepaid expenses. Deferred financing costs related to our unsecured revolving credit facility and leasing costs are amortized using the straight-line method over the terms of the respective agreements, which approximates the effective interest method. Should a tenant terminate its lease, the unamortized portion of the leasing cost is expensed. Unamortized deferred financing costs are expensed when the related agreements are terminated before their scheduled maturity dates. Lastly, the acquired development agreement and acquired ground lease intangible assets are amortized over the terms of the respective agreements as well.
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”).
Recognition of Share-based Compensation Expense	We grant share-based compensation awards to employees and trustees in the form of restricted common shares and cash settled awards, 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.
Income Tax Status	We made an election, 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, 2018 , 2017 , and 2016 , we sold various properties and land parcels at a gain, resulting in both a federal and state tax liability.
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 our joint ventures do not meet the requirements of a VIE and, therefore, consolidation of these ventures is not required.
Noncontrolling Interest in Subsidiaries	There are third parties who have certain noncontrolling interests in the Operating Partnership 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 is located outside the United States. Accordingly, we have a single reportable segment for disclosure purposes.
New Accounting Pronouncements, Policy	Recently Adopted Accounting Pronouncements In February 2017, the FASB issued ASU 2017-05 "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" ("ASU 2017-05"). ASU 2017-05 clarifies that a financial asset is within the scope of Subtopic 610-20 if it meets the definition of an in substance nonfinancial asset. ASU 2017-05 also defines the term "in substance nonfinancial asset". In addition, ASU 2017-05 eliminates the guidance specific to real estate sales in ASC 360-20. It became effective for annual periods beginning after December 15, 2017, therefore we adopted the standard on January 1, 2018. In doing so, the Company recorded an adjustment under the modified retrospective method of approximately $2.2 million to shareholders' equity associated with a transaction that occurred in the fourth quarter of 2017. The adjustment had no impact on earnings or cash flows. In May 2017, the FASB issued ASU 2017-09 "Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting" ("ASU 2017-09"). ASU 2017-09 clarifies guidance about what changes to the terms and conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. It became effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. The adoption of this standard did not have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU 2016-18 "Statement of Cash Flows." This new guidance became effective January 1, 2018, with early adoption permitted, and requires amounts that are generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The pronouncement requires a retrospective transition method of adoption. The adoption of this standard resulted in the reclassification of approximately $ 4.0 million of cash outflows from real estate acquisitions during the year ended December 31, 2017 and approximately $4.0 million of cash outflows from development and capital improvements during the year ended December 31, 2016 that were held in escrow as restricted cash. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balances sheets that reconciles to the total shown within the consolidated statements of cash flows. As of December 31, 2018 2017 2016 (In thousands) Cash and cash equivalents $ 41,064 $ 8,081 $ 3,582 Restricted cash and escrows 3,658 4,810 11,144 $ 44,722 $ 12,891 $ 14,726 Restricted cash generally consists of funds held in escrow by lenders to pay real estate taxes, insurance premiums and certain capital expenditures. In limited instances, restricted cash may include deposits on potential future acquisitions and/or proceeds related to dispositions of real estate. In August 2016, the FASB issued ASU 2016-15 "Classification of Certain Cash Receipts and Cash Payments" ("ASU 2016-15"), which clarifies the treatment of several cash flow categories. In addition, ASU 2016-15 clarifies that when cash receipts and cash payments have aspects of more than one class of cash flows and cannot be separated, classification will depend on the predominant source or use. This update became effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted, including adoption in an interim period. The adoption of this standard did not have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"). ASU 2014-09 is a comprehensive revenue recognition standard that superseded nearly all prior GAAP revenue recognition guidance as well as prior GAAP guidance governing the sale of non-financial assets. The standard’s core principle is that a company should recognize revenue when it satisfies performance obligations, by transferring promised goods or services to customers, in an amount that reflects the consideration to which the company expects to be entitled in exchange for fulfilling those performance obligations. In doing so, companies need to exercise more judgment and make more estimates than under prior GAAP guidance. ASU 2014-09 became effective for public entities for annual and interim reporting periods beginning after December 15, 2017 and early adoption was permitted in periods ending after December 15, 2016. The guidance permitted two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect initially applying the guidance recognized at the date of initial application (modified retrospective method). We adopted the standard and the related updates subsequently issued by the FASB using the modified retrospective method on January 1, 2018. ASU 2014-09 applies only to certain revenue included in Other Property Income and Management and Other Fee Income in our Consolidated Statement of Operations which approximate $4.1 million or less than 2.0% of total revenue. The timing of revenue recognition associated with these items remains substantially unchanged and no adjustment occurred upon adoption. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-13, "Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement", which amends ASC 820, Fair Value Measurement. ASU 2018-13 modified the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. This standard is effective for public companies for fiscal years beginning after December 15, 2019, including interim periods within that fiscal year. We are currently evaluating the guidance and have not determined the impact this standard may have on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting", which expands the scope of Topic 718, Compensation-Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. This standard is effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. The adoption of ASU 2018-07 is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-04 "Simplifying the Test for Goodwill Impairment" ("ASU 2017-04"). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. ASU 2017-04 is effective for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of ASU 2017-04 is not expected to have a material impact on our consolidated financial statements. In June 2016, the FASB updated Accounting Standards Codification ("ASC") Topic 326 "Financial Instruments - Credit Losses" with ASU 2016-13 “Measurement of Credit Losses on Financial Instruments” ("ASU 2016-13"). ASU 2016-13 enhances the methodology of measuring expected credit losses to include the use of forward-looking information to better inform credit loss estimates. In November 2018, the FASB subsequently issued ASU 2018-19, which clarifies that receivables arising from operating leases are not within the scope of the credit losses standard, but rather, should be accounted for in accordance with the leases standard. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within that fiscal year. We are currently evaluating the guidance and have not determined the impact this standard may have on our consolidated financial statements. In February 2016, the FASB updated ASC Topic 842 "Leases" ("ASU 2016-02"). ASU 2016-02 requires lessees to record operating and financing leases as assets and liabilities on the balance sheet and lessors to expense costs that are not direct leasing costs. In addition, the following ASUs were subsequently issued related to ASC Topic 842, all of which will be effective with ASU 2016-02: • In January 2018, the FASB issued ASU 2018-01, "Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842". The standard provides an optional transition practical expedient for the adoption of ASU 2016-02 that, if elected, would not require an organization to reconsider its accounting for existing land easements that are not currently accounted for under the old leases standard. • In July 2018, the FASB issued ASU 2018-10, "Codification Improvements to Topic 842, Leases", which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02. • In July 2018, the FASB issued ASU 2018-11, "Leases (Topic 842): Targeted Improvements", which provide lessors with a practical expedient, by class of underlying asset, to not separate nonlease components from the associated lease component and, instead, to account for those components as a single component if the nonlease components otherwise would be accounted for under the new revenue guidance (Topic 606) and certain criteria are met. The guidance also provides an optional transition method which would allow entities to initially apply the new guidance in the period of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings, if necessary. • In December 2018, the FASB issued ASU 2018-20, "Leases (Topic 842): Narrow-Scope Improvements for Lessors", which addresses specific issues in the leasing guidance, including sales taxes and other similar taxes collected from lessees, certain lessor costs paid directly by lessees, and recognition of variable payments for contracts with leases and nonlease components. ASU 2016-02 is effective for periods beginning after December 15, 2018, with early adoption permitted using a modified retrospective approach. The Company has elected the practical expedients allowable under ASU 2018-01 and ASU 2018-11, and has concluded the adoption of ASU 2016-02 will not have a material impact for operating leases where we are a lessor and we will continue to record revenues from rental properties for operating leases on a straight-line basis. In addition, for leases where the Company is a lessee, primarily the Company’s ground lease and administrative office leases, the Company will record a lease liability of $16.6 million and a right of use asset of $18.0 million upon adoption related to these items. Additionally, only incremental direct leasing costs will be capitalized under this new guidance and expect to recognize a cumulative effect adjustment to accumulated distributions in excess of net income of primarily relating to certain costs associated with unexecuted leases that were deferred of $0.4 million as of December 31, 2018 . The Company has adopted this new guidance effective on January 1, 2019.
