Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Washington Prime Group Inc. (“WPG Inc.”) is an Indiana corporation that operates as a fully integrated, self‑administered and self‑managed real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended (the "Code"). WPG Inc. will generally qualify as a REIT for U.S. federal income tax purposes as long as it continues to distribute at least 90% of its REIT taxable income and satisfy certain other requirements. WPG Inc. will generally be allowed a deduction against its U.S. federal income tax liability for dividends paid by it to REIT shareholders, thereby reducing or eliminating any corporate level taxation to WPG Inc. Washington Prime Group, L.P. (“WPG L.P.”) is WPG Inc.'s majority‑owned limited partnership subsidiary that owns, develops and manages, through its affiliates, all of WPG Inc.'s real estate properties and other assets. WPG Inc. is the sole general partner of WPG L.P. As of June 30, 2019 , our assets consisted of material interests in 108 shopping centers in the United States, consisting of open air properties and enclosed retail properties, comprised of approximately 56 million square feet of managed gross leasable area. Unless the context otherwise requires, references to "WPG," the "Company," “we,” “us” or “our” refer to WPG Inc., WPG L.P. and entities in which WPG Inc. or WPG L.P. (or any affiliate) has a material ownership or financial interest, on a consolidated basis. We derive our revenues primarily from retail tenant leases, including fixed minimum rent leases, overage and percentage rent leases based on tenants’ sales volumes, offering property operating services to our tenants and others, including energy, waste handling and facility services, and reimbursements from tenants for certain recoverable costs such as property operating, real estate taxes, repair and maintenance, and advertising and promotional expenses. We seek to enhance the performance of our properties and increase our revenues by, among other things, securing leases of anchor and inline tenant spaces, re‑developing or renovating existing properties to increase the leasable square footage, and increasing the productivity of occupied locations through aesthetic upgrades, re‑merchandising and/or changes to the retail use of the space. Severance On February 5, 2019 , the Company's Executive Vice President, Head of Open Air Centers was terminated without cause from his position and received severance payments and other benefits pursuant to the terms and conditions of his employment agreement. In addition, the Company terminated, without cause, additional non-executive personnel in the Property Management department as part of an effort to reduce overhead costs. In connection with and as part of the aforementioned management changes, the Company recorded aggregate severance charges of $1.9 million , including $0.1 million of non-cash stock compensation in the form of accelerated vesting of equity incentive awards, which costs are included in general and administrative expense in the accompanying consolidated statements of operations and comprehensive (loss) income for the six months ended June 30, 2019 . On March 18, 2019 , the Company's Executive Vice President, Development notified the Company of his resignation. The effective date of his resignation was March 28, 2019. There were no severance payments or accelerated vesting of stock compensation benefits in connection with this separation. On May 7, 2018 , the Company's Executive Vice President, Property Management was terminated without cause from his position and received severance payments and other benefits pursuant to the terms and conditions of his employment agreement. In addition, the Company terminated without cause additional non-executive personnel in the Property Management department. In connection with and as part of the aforementioned management and personnel changes, the Company recorded aggregate severance charges of $2.0 million , including $0.5 million of non-cash stock compensation in the form of accelerated vesting of equity incentive awards, which costs are included in general and administrative expense in the accompanying consolidated statements of operations and comprehensive (loss) income for the three and six months ended June 30, 2018

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated balance sheets as of June 30, 2019 and December 31, 2018 include the accounts of WPG Inc. and WPG L.P., as well as their majority owned and controlled subsidiaries. The accompanying consolidated statements of operations include the consolidated accounts of the Company. All intercompany transactions have been eliminated in consolidation. Due to the seasonal nature of certain operational activities, the results for the interim period ended June 30, 2019 are not necessarily indicative of the results to be expected for the full year. These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by GAAP for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary to present fairly the financial position of the Company and its results of operations and cash flows for the interim periods presented. The Company believes that the disclosures made are adequate to prevent the information presented from being misleading. These consolidated unaudited financial statements should be read in conjunction with the audited consolidated and combined financial statements and related notes included in the combined 2018 Annual Report on Form 10-K for WPG Inc. and WPG L.P. (the " 2018 Form 10-K"). General These consolidated financial statements reflect the consolidation of properties that are wholly owned or properties in which we own less than a 100% interest but that we control. Control of a property is demonstrated by, among other factors, our ability, without the consent of any other unaffiliated partner or owner, to refinance debt or sell the property and the inability of any other unaffiliated partner or owner to replace us. We consolidate a variable interest entity ("VIE") when we are determined to be the primary beneficiary. Determination of the primary beneficiary of a VIE is based on whether an entity has (1) the power to direct activities that most significantly impact the economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary of a VIE considers all relationships between us and the VIE, including management agreements and other contractual arrangements. During the three and six months ended June 30, 2019 , we sold our interest in undeveloped land that was previously identified as a VIE. As of June 30, 2019 , we have one VIE, which consists of our interest in WPG L.P. During the six months ended June 30, 2019 , we did not provide financial or other support to a previously identified VIE that we were not previously contractually obligated to provide. Investments in partnerships and joint ventures represent our noncontrolling ownership interests in properties. We account for these investments using the equity method of accounting. We initially record these investments at cost and we subsequently adjust for net equity in income or loss, which we allocate in accordance with the provisions of the applicable partnership or joint venture agreement and cash contributions and distributions, if applicable. The allocation provisions in the partnership or joint venture agreements are not always consistent with the legal ownership interests held by each general or limited partner or joint venture investee primarily due to partner preferences. We separately report investments in joint ventures for which accumulated distributions have exceeded investments in and our share of net income from the joint ventures within cash distributions and losses in unconsolidated entities, at equity in the consolidated balance sheets. The net equity of certain joint ventures is less than zero because of financing or operating distributions that are usually greater than net income, as net income includes non-cash charges for depreciation and amortization, and WPG has historically committed to or intends to fund the venture. As of June 30, 2019 , our assets consisted of material interests in 108 shopping centers. The consolidated financial statements as of that date reflect the consolidation of 91 wholly owned properties and four additional properties that are less than wholly owned, but which we control or for which we are the primary beneficiary. We account for our interests in the remaining 13 properties, or the joint venture properties, using the equity method of accounting. While we manage the day-to-day operations of the joint venture properties, we do not control the operations as we have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties (see Note 5 - "Investment in Unconsolidated Entities, at Equity" for further details). We allocate net operating results of WPG L.P. to third parties and to WPG Inc. based on the partners' respective weighted average ownership interests in WPG L.P. Net operating results of WPG L.P. attributable to third parties are reflected in net (loss) income attributable to noncontrolling interests. WPG Inc.'s weighted average ownership interest in WPG L.P. was 84.4% and 84.4% for the six months ended June 30, 2019 and 2018 . As of June 30, 2019 and December 31, 2018 , WPG Inc.'s ownership interest in WPG L.P. was 84.4% and 84.4% . We adjust the noncontrolling limited partners' interests at the end of each period to reflect their interest in WPG L.P.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Fair Value Measurements The Company measures and discloses its fair value measurements in accordance with Accounting Standards Codification ("ASC") Topic 820 - “Fair Value Measurement” (“Topic 820”). The fair value hierarchy, as defined by Topic 820, contains three levels of inputs that may be used to measure fair value as follows: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. • Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, such as interest rates, foreign exchange rates, and yield curves, that are observable at commonly quoted intervals. • Level 3 inputs are unobservable inputs for the asset or liability which are typically based on an entity's own assumptions, as there is little, if any, related market activity. The asset or liability's fair value within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Under Topic 820, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction at the measurement date and under current market conditions. Use of Estimates We prepared the accompanying consolidated financial statements in accordance with GAAP. This requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reported period. Our actual results could differ from these estimates. Segment Disclosure Our primary business is the ownership, development and management of retail real estate. We have aggregated our operations, including enclosed retail properties and open air properties, into one reportable segment because they have similar economic characteristics and we provide similar products and services to similar types of, and in many cases, the same tenants. New Accounting Pronouncements Adoption of New Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." This new guidance, including related ASUs that were subsequently issued, was effective January 1, 2019 and required lessees to recognize a lease liability and right of use ("ROU") asset, measured as the present value of lease payments, for both operating and financing leases with a term greater than 12 months. Additionally, the new standard made targeted changes to lessor accounting. The new leases standard required a modified retrospective transition approach for all leases existing at, or entered into after, January 1, 2017, with an option to use certain transition relief which allowed an entity to account for the impact of the adoption ASU 2016-02 with a cumulative adjustment to retained earnings, if necessary, on January 1, 2019, rather than January 1, 2017, eliminating the need to restate amounts presented prior to January 1, 2019. The Company adopted the new standard on January 1, 2019 and applied the new guidance utilizing the optional transition method noted above. The Company elected to use the "package of practical expedients," which allowed the Company not to reassess under the new standard prior conclusions about lease identification, lease classification, and initial direct costs. The Company did not make any adjustments to the opening balance of retained earnings upon adoption of the new standard given the nature of the impacts and other transition practical expedients elected by the Company. Upon adoption, the Company recognized a lease liability and corresponding ROU asset of approximately $14.4 million for the four material ground leases, two material office leases, and one material garage lease with a term of more than 12 months. For leases with a term of 12 months or less, the Company made an accounting policy election by underlying asset to not recognize lease liabilities and ROU assets. Additionally, the Company excluded certain office equipment leases due to materiality. All of these leases were classified as operating leases under legacy GAAP and the current classification was carried forward under ASU 2016-02. See "Note 10 - Commitments and Contingencies" for additional details. From a lessor perspective, the new guidance remained mostly similar to legacy GAAP as the Company elected the practical expedient to not separate non-lease components from lease components. This election resulted in a change on the Company's consolidated statements of operations and comprehensive (loss) income as the Company no longer presents minimum rents, overage rents, and tenant reimbursements as separate line items because the Company now accounts for these line items as a single combined lease component, rental income, on the basis of the lease component being the predominant component of the contract. As such, non-lease components, including common-area ("CAM") revenues, are now combined with lease components and are recognized on a straight-line basis to the extent the non-lease components are fixed. Additionally, ASU 2016-02 required the Company to recognize a change, after the commencement date, in their assessment of whether the collectibility of an operating lease receivable as probable as an adjustment to rental income rather than as a provision for credit losses. This requirement resulted in a change on the Company's consolidated statements of operations and comprehensive (loss) income as the Company no longer presents provision for credit losses as a separate line item and the adjustment is now recorded as a reduction to rental income. ASU 2016-02 also introduced certain changes to the lease classification rules for lessors. Accordingly, some leases may be classified as sales-type leases in the future. This change is not expected to have a material impact on the Company's financial statements. Finally, ASU 2016-02 disallowed the capitalization of internal leasing costs and legal costs, unless said costs are incremental to obtaining the lease contract, resulting in an increase in the Company's general and administrative expenses. For the three and six months ended June 30, 2018 , we capitalized approximately $4.6 million and $8.7 million of internal legal and leasing costs, respectively, that would no longer qualify for capitalization under the new standard. The Company elected to use the practical expedient in transition to not re-evaluate costs that were previously capitalized. The cumulative effect of the change to our consolidated January 1, 2019 balance sheet for the adoption of ASU 2016-02 was as follows: Balance at December 31, 2018 Adjustments Due to Balance at January 1, 2019 Balance Sheet Assets Deferred costs and other assets $ 169,135 $ 14,412 $ 183,547 Liabilities Accounts payable, accrued expenses, intangibles, and deferred revenues $ 253,862 $ 14,412 $ 268,274 New Standards Issued But Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurements (ASC 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurements." ASU 2018-13 eliminates certain disclosure requirements for all entities, requires public entities to disclose certain new information, and modifies some disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact this ASU will have, if any, on our financial statements and related disclosures. Reclassifications Reclassifications were made to conform prior periods to our presentation of the consolidated statements of operations and comprehensive (loss) income due to the impact of adopting ASU 2016-02. Amounts previously disclosed as minimum rent, tenant reimbursements, and overage rent during the three and six months ended June 30, 2018 are now included in rental income and will no longer be presented as separate line items. Additionally, termination income of $0.3 million and $2.0 million , which was previously disclosed in other income, and provision for credit losses of $0.6 million and $4.0 million , which was previously disclosed as a separate line item during the three and six months ended June 30, 2018 , respectively, were also reclassified to rental income to conform with the impact of adopting ASU 2016-02. Reconciliation of Cash, Cash Equivalents, and Restricted Cash The following is a summary of our beginning and ending cash, cash equivalents and restricted cash totals as presented in our statements of cash flows for the six months ended June 30, 2019 and 2018 : Balance at June 30, Balance at December 31, 2019 2018 2018 2017 Cash and cash equivalents $ 30,683 $ 53,987 $ 42,542 $ 52,019 Restricted cash 49,593 29,127 18,542 18,182 Total cash, cash equivalents and restricted cash $ 80,276 $ 83,114 $ 61,084 $ 70,201 Restricted cash primarily relates to cash held in escrow for payment of real estate taxes and property reserves for maintenance, expansion or leasehold improvements as required by our mortgage loans. Restricted cash is included in "Deferred costs and other assets" in the accompanying balance sheets as of June 30, 2019 and December 31, 2018 .

Discontinued Operations and Disposal Groups [Abstract]
Investment in Real Estate	Investment in Real Estate 2018 Acquisitions On April 11, 2018 , we acquired, through a sale-leaseback transaction, four Sears department stores and adjacent Sears Auto Centers at Longview Mall, located in Longview, Texas; Polaris Fashion Place®, located in Columbus, Ohio; Southern Hills Mall, located in Sioux City, Iowa; and Town Center at Aurora, located in Aurora, Colorado. The purchase price was approximately $28.5 million and was funded by a combination of $13.4 million from our Facility (as defined in Note 6 - "Indebtedness"), $9.7 million from the first tranche of the Four Corners transaction, as discussed below, and $5.4 million from O'Connor Mall Partners, L.P. ("O'Connor") related to their pro-rata share of the joint venture that owns Polaris Fashion Place® (see Note 5 - "Investment in Unconsolidated Entities, at Equity"). On April 24, 2018 , the Company closed on the acquisition of Southgate Mall, located in Missoula, Montana, for $58.0 million , which was funded from our Facility (as defined in Note 6 - "Indebtedness"). The following table summarizes the fair value allocation for the acquisitions, which was finalized during the three months ended June 30, 2018: Investment properties $ 72,647 Investment in and advances to unconsolidated entities, at equity 5,543 Deferred costs and other assets 10,311 Accounts payable, accrued expenses, intangibles, and deferred revenue (8,393 ) Net cash paid for acquisitions $ 80,108 Intangibles of $10.3 million , which relate primarily to above-market leases and lease in place values, are included in “Deferred costs and other assets” as of the respective acquisition dates. The initial weighted average useful life of the intangible assets was 11.5 years .

The mortgage note payable requires monthly principal and interest payments and will mature on May 6, 2029. The net proceeds were primarily used to reduce corporate debt. On April 8, 2019 , the Company exercised the second of three options to extend the maturity date of the $65.0 million term loan secured by Weberstown Mall, located in Stockton, California, for one year. The extended maturity date is June 8, 2020, subject to a one -year extension available at our option subject to compliance with the terms of the underlying loan agreement and payment of customary extension fees. During the six months ended June 30, 2019 , the Company exercised the first of two options to extend the maturity of the $52.0 million mortgage note payable on Town Center at Aurora for one year . The extended maturity date is April 1, 2020, subject to a one-year extension available at our option subject to compliance with the terms of the underlying loan agreement and payment of customary extension fees. Pursuant to the terms of the extension option, the Company entered into a derivative swap agreement to fix the interest rate of the note payable at one-month LIBOR plus 2.27% per annum through both extension periods. At June 30, 2019 , the interest rate on the note payable was 4.67% . Unsecured Debt During the six months ended June 30, 2019 , Fitch Ratings, Moody's Investor Service, and S&P Global Ratings lowered their credit rating on WPG L.P.'s unsecured long-term indebtedness, which increased interest rates on our Facility, December 2015 Term Loan, and Senior Notes due 2024 (see below definitions to these for capitalized terms). Due to the downgrade and based upon current leverage levels, as of June 30, 2019 , our Revolver bears interest at LIBOR plus 1.80% (an increase of 55 basis points), our Term Loan bears interest at LIBOR plus 2.10% (an increase of 55 basis points), and our December 2015 Term Loan bears interest at LIBOR plus 2.35% (an increase of 55 basis points). Our Senior Notes due 2024 will bear interest at 6.450% , effective August 15, 2019 (an increase of 50 basis points). The following table identifies our total unsecured debt outstanding at June 30, 2019 and December 31, 2018 : June 30, December 31, Notes payable: Face amount - the Exchange Notes (1) $ 250,000 $ 250,000 Face amount - Senior Notes due 2024 (2) 750,000 750,000 Debt discount, net (8,944 ) (9,680 ) Debt issuance costs, net (6,664 ) (7,623 ) Total carrying value of notes payable $ 984,392 $ 982,697 Unsecured term loans: (7) Face amount - Term Loan (3)(4) $ 350,000 $ 350,000 Face amount - December 2015 Term Loan (5) 340,000 340,000 Debt issuance costs, net (3,924 ) (4,491 ) Total carrying value of unsecured term loans $ 686,076 $ 685,509 Revolving credit facility: (3)(6) Face amount $ 222,000 $ 290,000 Debt issuance costs, net (3,427 ) (3,998 ) Total carrying value of revolving credit facility $ 218,573 $ 286,002 (1) The Exchange Notes were issued at a 0.028% discount, bear interest at 3.850% per annum and mature on April 1, 2020 . (2) The Senior Notes due 2024 were issued at a 1.533% discount, bear interest at 5.950% per annum through August 14, 2019, at which time the interest rate will increase to 6.450% per annum due to the credit downgrade. The Senior Notes due 2024 mature on August 15, 2024 . The interest rate could vary in the future based upon changes to the Company's credit ratings. (3) The unsecured revolving credit facility, or "Revolver" and unsecured term loan, or "Term Loan" are collectively known as the "Facility." (4) The Term Loan bears interest at one-month LIBOR plus 2.10% per annum and will mature on December 30, 2022 . We have interest rate swap agreements totaling $250.0 million , which effectively fix the interest rate on a portion of the Term Loan at 4.86% through June 30, 2021 . At June 30, 2019 , the applicable interest rate on the unhedged portion of the Term Loan was one-month LIBOR plus 2.10% or 4.50% . (5) The December 2015 Term Loan bears interest at one-month LIBOR plus 2.35% per annum and will mature on January 10, 2023 . We have interest rate swap agreements totaling $340.0 million which effectively fix the interest rate at 4.06% per annum through maturity. (6) The Revolver provides borrowings on a revolving basis up to $650.0 million , bears interest at one-month LIBOR plus 1.80% , and will initially mature on December 30, 2021 , subject to two six month extensions available at our option subject to compliance with terms of the Facility and payment of a customary extension fee. At June 30, 2019 , we had an aggregate available borrowing capacity of $427.8 million under the Revolver, net of $0.2 million reserved for outstanding letters of credit. At June 30, 2019 , the applicable interest rate on the Revolver was one-month LIBOR plus 1.80% or 4.20% . The interest rate on the Revolver may vary in the future based upon the Company's credit rating and leveraged levels. (7) While we have interest rate swap agreements in place that fix the LIBOR portion of the rates as noted above, the spread over LIBOR could vary in the future based upon changes to the Company's credit ratings and leveraged levels. Covenants Our unsecured debt agreements contain financial and other covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender including adjustments to the applicable interest rate. As of June 30, 2019, management believes the Company is in compliance with all covenants of its unsecured debt. The total balance of mortgages was approximately $1.2 billion as of June 30, 2019 . At June 30, 2019 , certain of our consolidated subsidiaries were the borrowers under 22 non-recourse loans and two full-recourse loans secured by mortgages encumbering 27 properties, including one separate pool of cross-defaulted and cross-collateralized mortgages encumbering a total of four properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt instruments contain financial and other non-financial covenants which are specific to the properties which serve as collateral for that debt. If the borrower fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. Our existing non-recourse mortgage loans generally prohibit our subsidiaries that are borrowers thereunder from incurring additional indebtedness, subject to certain customary and limited exceptions. In addition, certain of these instruments limit the ability of the applicable borrower's parent entity from incurring mezzanine indebtedness unless certain conditions are satisfied, including compliance with maximum loan to value ratio and minimum debt service coverage ratio tests. Further, under certain of these existing agreements, if certain cash flow levels in respect of the applicable mortgaged property (as described in the applicable agreement) are not maintained for at least two consecutive quarters, the lender could accelerate the debt and enforce its right against its collateral. On November 19, 2018 , we received a notice of default letter, dated November 15, 2018 , from the special servicer to the borrower, a consolidated subsidiary of WPG L.P., concerning the $49.8 million mortgage loan secured by West Ridge Mall and West Ridge Plaza, located in Topeka, Kansas (collectively known as "West Ridge"). The notice was issued by the special servicer because the borrower did not make certain reserve repayments or deposits as required by the loan agreement for the aforementioned loan. On May 9, 2019, we received notification that a receiver had been appointed to manage and lease West Ridge. An affiliate of the Company still holds title to the property. On April 11, 2018 , we received a notice of default letter, dated April 6, 2018 , from the special servicer to the borrower, a consolidated subsidiary of WPG L.P., concerning the $45.2 million mortgage loan secured by Towne West Square, located in Wichita, Kansas. The notice was issued by the special servicer because the borrower did not make certain reserve payments or deposits as required by the loan agreement for the aforementioned loan. On July 1, 2019 , an affiliate of the Company transitioned the property to the lender (see Note 12 - "Subsequent Events"). At June 30, 2019 , management believes the applicable borrowers under our other non-recourse mortgage loans were in compliance with all covenants where non-compliance could individually, or giving effect to applicable cross-default provisions in the aggregate, have a material adverse effect on our financial condition, results of operations or cash flows. The Company has assessed each of the defaulted properties for impairment indicators and have concluded no impairment charges were warranted as of June 30, 2019. Fair Value of Debt The carrying values of our variable-rate loans approximate their fair values. We estimate the fair values of fixed-rate mortgages and fixed-rate unsecured debt (including variable-rate unsecured debt swapped to fixed-rate) using cash flows discounted at current borrowing rates or Level 2 inputs. We estimate the fair values of consolidated fixed-rate unsecured notes payable using quoted market prices, or, if no quoted market prices are available, we use quoted market prices for securities with similar terms and maturities or Level 1 inputs. The book value and fair value of these financial instruments and the related discount rate assumptions as of June 30, 2019 and December 31, 2018 are summarized as follows: June 30, 2019 December 31, 2018 Book value of fixed-rate mortgages (1) $1,086,630 $915,276 Fair value of fixed-rate mortgages $1,109,770 $928,129 Weighted average discount rates assumed in calculation of fair value for fixed-rate mortgages 4.41 % 4.57 % Book value of fixed-rate unsecured debt (1) $1,590,000 $1,590,000 Fair value of fixed-rate unsecured debt $1,538,812 $1,485,672 Weighted average discount rates assumed in calculation of fair value for fixed-rate unsecured debt 5.52 % 5.62 % (1) Excludes debt issuance costs and applicable debt discounts.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its debt funding and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future uncertain cash amounts, the value of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash payments related to the Company's borrowings. Cash Flow Hedges of Interest Rate Risk The Company's objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish these objectives the Company primarily uses interest rate swaps or caps as part of its interest rate risk management strategy. Interest rate swaps involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company may also enter into forward starting swaps or treasury lock agreements to set the effective interest rate on a planned fixed-rate financing. In a forward starting swap or treasury lock agreement that the Company cash settles in anticipation of a fixed rate financing or refinancing, the Company will receive or pay an amount equal to the present value of future cash flow payments based on the difference between the contract rate and market rate on the settlement date. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in other comprehensive income ("OCI") or other comprehensive loss (“OCL”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Net realized gains or losses resulting from derivatives that were settled in conjunction with planned fixed-rate financings or refinancings continue to be included in accumulated other comprehensive income ("AOCI") during the term of the hedged debt transaction. Amounts reported in AOCI relate to derivatives that will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. Realized gains or losses on settled derivative instruments included in AOCI are recognized as an adjustment to income over the term of the hedged debt transaction. During the next twelve months, the Company estimates that an additional $1.9 million will be reclassified as an increase to interest expense. On March 29, 2019 , the Company entered into one two-year swap, totaling $52.0 million with an effective date of April 1, 2019 , pursuant to the terms of the extension option executed on the mortgage note payable loan at Town Center at Aurora. As of June 30, 2019 , the Company had 11 outstanding interest rate derivatives that were designated as cash flow hedges of interest rate risk with a current notional value of $641.8 million . The table below presents the fair value of the Company's derivative financial instruments as well as their classification on the consolidated balance sheets as of June 30, 2019 and December 31, 2018 : Derivatives designated as hedging instruments: Balance Sheet June 30, 2019 December 31, 2018 Interest rate products Asset derivatives Deferred costs and other assets $ — $ 9,306 Interest rate products Liability derivatives Accounts payable, accrued expenses, intangibles, and deferred revenue $ 7,144 $ 1,913 The asset derivative instruments were reported at their fair value of $0 and $9,306 in deferred costs and other assets at June 30, 2019 and December 31, 2018 , respectively, with a corresponding adjustment to OCI for the unrealized gains and losses (net of noncontrolling interest allocation). The liability derivative instruments were reported at their fair value of $7,144 and $1,913 at June 30, 2019 and December 31, 2018 , respectively, with a corresponding adjustment to OCL for the unrealized gains and losses (net of noncontrolling interest allocation). Over time, the unrealized gains and losses held in AOCI will be reclassified to earnings. This reclassification will correlate with the recognition of the hedged interest payments in earnings. The table below presents the effect of the Company's derivative financial instruments on the consolidated statements of comprehensive (loss) income for the three and six months ended June 30, 2019 and 2018 : Derivatives in Cash Flow Hedging Relationships Location of Gain or Loss Recognized in Income on Derivatives For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 Amount of (Loss) or Gain Recognized in OCI on Derivative Interest expense $ (8,955 ) $ 1,850 $ (13,520 ) $ 7,847 Amount of Gain Reclassified from AOCI into Income Interest expense $ (530 ) $ (1,248 ) $ (1,075 ) $ (2,028 ) The table below presents the effect of the Company's derivative financial instruments on the consolidated statements of operations for the three and six months ended June 30, 2019 and 2018 : Effect of Cash Flow Hedges on Consolidated Statements of Operations For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 Total interest expense presented in the consolidated statements of operations in which the effects of cash flow hedges are recorded $ (39,143 ) $ (34,701 ) $ (75,973 ) $ (69,045 ) Amount of gain reclassified from accumulated other comprehensive income into interest expense $ (530 ) $ (1,248 ) $ (1,075 ) $ (2,028 ) Credit Risk-Related Contingent Features The Company has agreements with each of its derivative counterparties that contain a provision that if the Company either defaults or is capable of being declared in default on any of its consolidated indebtedness, then the Company could also be declared in default on its derivative obligations. The Company has agreements with its derivative counterparties that incorporate the loan covenant provisions of the Company's indebtedness with a lender affiliate of the derivative counterparty. Failure to comply with the loan covenant provisions would result in the Company being in default on any derivative instrument obligations covered by the agreement. As of June 30, 2019 , the fair value of the derivatives in a net liability position, plus accrued interest but excluding any adjustment for nonperformance risk, related to these agreements was $7,144 . As of June 30, 2019 , the Company has not posted any collateral related to these agreements. The Company is not in default with any of these provisions as of June 30, 2019 . If the Company had breached any of these provisions at June 30, 2019 , it would have been required to settle its obligation under these agreements at their termination value of $7,144 . Fair Value Considerations Currently, the Company uses interest rate swaps and caps to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. Based on these inputs the Company has determined that its interest rate swap and cap valuations are classified within Level 2 of the fair value hierarchy. To comply with the provisions of Topic 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of June 30, 2019 and December 31, 2018 , the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. The tables below presents the Company’s net assets and liabilities measured at fair value as of June 30, 2019 and December 31, 2018 aggregated by the level in the fair value hierarchy within which those measurements fall: Quoted Prices in Active Markets for Identical Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balance at June 30, 2019 Derivative instruments, net $ — $ (7,144 ) $ — $ (7,144 ) Quoted Prices in Active Markets for Identical Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balance at December 31, 2018 Derivative instruments, net $ — $ 7,393 $ — $ 7,393

The majority of these leases contain extension options, typically at the lessee's election, and/or early termination provisions. Further, our leases do not contain any provisions that would allow the lessee to purchase the underlying assets throughout the lease term. In most cases, consideration received typically includes a fixed minimum rent component, reimbursement of a fixed portion of our property operating expenses, including utility, security, janitorial, landscaping, food court and other administrative expenses (also known as CAM), and reimbursement of lessor costs such as real estate taxes and insurance, computed based upon a formula in accordance with the lease terms. When not reimbursed by the fixed CAM component, CAM expense reimbursements and lessor costs are based on the tenant's proportionate share of the allocable operating expenses and CAM capital expenditures for the property. We accrue reimbursements from tenants for recoverable portions of all these expenses as revenue in the period the applicable expenditures are incurred. We recognize differences between estimated recoveries and the final billed amounts in the subsequent year. Additionally, a large number of our tenants are also required to pay overage rents based on sales during the applicable lease year over a base amount stated in the lease agreement. We recognize overage rents only when each tenant's sales exceed the applicable sales threshold as defined in their lease. We also collect lease termination income from tenants to allow for the tenant to vacate their space prior to their scheduled lease termination date. We recognize lease termination income in the period when a termination agreement is signed, collectability is assured, and we are no longer obligated to provide space to the tenant. In the event that a tenant is in bankruptcy when the termination agreement is signed, termination fee income is deferred and recognized when, and if, it is received. We record an adjustment to rental income in the period there is a change in our assessment of whether the collectibility of an operating lease receivable is probable. We have elected the practical expedient in ASU 2016-02 to not separate non-lease components from lease components as our underlying leases qualify as operating leases and the timing and pattern of transfer of the lease and non-lease components are the same. We note that the predominant component of our leases is the lease component and thus account for the combined lease and non-lease component of the non-cancelable lease term on a straight-line basis in accordance with ASC 842. Rental income also includes accretion related to above-market and below-market lease intangibles related to the acquisition of operating properties. We amortize any tenant inducements as a reduction of rental income utilizing the straight-line method over the term of the related lease or occupancy term of the tenant, if shorter. The following table summarizes our rental income for the three and six months ended June 30, 2019 and 2018 : For the Three Months Ended June 30, For the Six Months Ended June 30, 2019 2018 2019 2018 Operating lease payments, fixed $ 138,173 $ 152,154 $ 282,349 $ 306,132 Operating lease payments, variable 16,397 16,903 34,459 34,880 Amortization of straight-line rent, inducements, and rent abatements 1,163 921 2,272 1,681 Net amortization/accretion of above and below-market leases 1,544 1,076 4,450 4,124 Change in estimate of collectibility of rental income (1,047 ) (611 ) (4,027 ) (3,957 ) Total rental income $ 156,230 $ 170,443 $ 319,503 $ 342,860 Future payments to be received under non-cancelable operating leases for each of the next five years and thereafter, excluding variable payments of tenant reimbursements, percentage or overage rents, and lease termination payments as of June 30, 2019 are as follows: 2019 (July - December) $ 267,470 2020 432,521 2021 355,883 2022 296,456 2023 238,734 Thereafter 747,476 $ 2,338,540

Equity [Abstract]
Equity	Equity Exchange Rights Subject to the terms of the limited partnership agreement of WPG L.P., limited partners in WPG L.P. have, at their option, the right to exchange all or any portion of their units for shares of WPG Inc. common stock on a one‑for‑one basis or cash, as determined by WPG Inc. Therefore, the common units held by limited partners are considered by WPG Inc. to be share equivalents and classified as noncontrolling interests within permanent equity, and classified by WPG L.P. as permanent equity. The amount of cash to be paid if the exchange right is exercised and the cash option is selected will be based on the market value of WPG Inc.'s common stock as determined pursuant to the terms of the WPG L.P. Partnership Agreement. At June 30, 2019 , WPG Inc. had reserved 34,752,111 shares of common stock for possible issuance upon the exchange of units held by limited partners. The holders of the Series I-1 Preferred Units have, at their option, the right to have their units purchased by WPG L.P. subject to the satisfaction of certain conditions. Therefore, the Series I-1 Preferred Units are classified as redeemable noncontrolling interests outside of permanent equity. Stock Based Compensation On May 28, 2014 , the WPG Inc. Board of Directors (the "Board") adopted the Washington Prime Group, L.P. 2014 Stock Incentive Plan (the "2014 Plan"), which permitted the Company to grant awards to current and prospective directors, officers, employees and consultants of the Company or any affiliate. An aggregate of 10,000,000 shares of common stock were reserved for issuance, with a maximum number of awards to be granted to a participant in any calendar year of 500,000 shares/units. On May 16, 2019, the common shareholders of WPG Inc. approved the Washington Prime Group, L.P. 2019 Stock Incentive Plan (the "2019 Plan"), which replaced the 2014 Plan. The Board and its Compensation Committee (the "Committee") previously approved and adopted the 2019 Plan, subject to WPG Inc. common shareholder approval, during the Board and Committee's regular meetings in February 2019. An aggregate of 7,290,000 shares of common stock are reserved for issuance, excluding carryover shares from the 2014 Plan. Awards may be in the form of stock options, stock appreciation rights, restricted stock, restricted stock units ("RSUs") or other stock-based awards in WPG Inc., long term incentive units ("LTIP units" or "LTIPs") or performance units ("Performance LTIP Units") in WPG L.P. The 2019 Plan terminates on May 16, 2029. The following is a summary by type of the awards that the Company issued during the six months ended June 30, 2019 and June 30, 2018 under the 2014 Plan and 2019 Plan. Annual Long-Term Incentive Awards During the six months ended June 30, 2019 and 2018 , the Company approved the terms and conditions of the 2019 and 2018 annual awards (the "2019 Annual Long-Term Incentive Awards" and "2018 Long-Term Incentive Awards," respectively) for certain executive officers and employees of the Company. Under the terms of the awards program, each participant is provided the opportunity to receive (i) time-based RSUs and (ii) performance-based stock units ("PSUs"). RSUs represent a contingent right to receive one WPG Inc. common share for each vested RSU. RSUs will vest in one-third installments on each annual anniversary of the respective Grant Date (as referenced below), subject to the participant's continued employment with the Company through each vesting date and the participant's continued compliance with certain applicable covenants. During the service period, dividend equivalents will be paid with respect to the RSUs corresponding to the amount of any dividends paid by the Company to the Company's common shareholders for the applicable dividend payment dates. Compensation expense is recognized on a straight-line basis over the three year vesting term. Actual PSUs earned may range from 0% - 150% of the PSUs allocated to the award recipient, based on the Company's total shareholder return ("TSR") compared to a peer group based on companies with similar assets and revenue over a three-year performance period that commenced on the respective Grant Date (as referenced below). During the performance period, dividend equivalents corresponding to the amount of any regular cash dividends paid by the Company to the Company’s common shareholders for the applicable dividend payment dates will accrue and be deemed reinvested in additional PSUs, which will be settled in common shares at the same time and only to the extent that the underlying PSU is earned and settled in common shares. Payout of the PSUs is also subject to the participant’s continued employment with the Company through the end of the performance period. The PSUs were valued through the use of a Monte Carlo model and the related compensation expense is recognized over the three-year performance period. The following table summarizes the issuance of the 2019 Annual Long-Term Incentive Awards and 2018 Annual Long-Term Incentive Awards, respectively: 2019 Annual Long-Term Incentive Awards 2018 Annual Long-Term Incentive Awards Grant Date February 20, 2019 February 20, 2018 RSUs issued 572,163 587,000 Grant date fair value per unit $5.77 $6.10 PSUs issued 572,163 587,000 Grant date fair value per unit $4.98 $4.88 WPG Restricted Stock Units During the six months ended June 30, 2019 and 2018 , the Company awarded 331,792 RSUs, with a grant date fair value of $1.5 million , and 225,440 RSUs, with a grant-date fair value of $1.5 million , respectively, to certain employees and non-employee members of the Board. The RSUs are service-based awards and the related fair value is expensed over the applicable service periods, except in instances that result in accelerated vesting due to severance arrangements or retirement of Board members. Stock Options During the six months ended June 30, 2019 , no stock options were granted to employees, 391 stock options were exercised by employees and 52,152 stock options were canceled, forfeited or expired. As of June 30, 2019 , there were 627,198 stock options outstanding. During the six months ended June 30, 2018 , no stock options were granted to employees, no stock options were exercised by employees and 108,081 stock options were canceled, forfeited or expired. Share Award Related Compensation Expense During the three and six months ended June 30, 2019 , the Company recorded compensation expense pertaining to the awards granted of $2.0 million and $3.8 million , respectively, in general and administrative and property operating expense within the consolidated statements of operations and comprehensive (loss) income. During the three and six months ended June 30, 2018 , the Company recorded compensation expense pertaining to the awards granted of $2.5 million and $4.3 million , respectively, in general and administrative and property operating expense within the consolidated statements of operations and comprehensive (loss) income. In certain instances, employment agreements and stock compensation programs provide for accelerated vesting when executives are terminated without cause. Additionally, the Committee may, in its discretion, accelerate the vesting for retiring Board members. Distributions During the three and six months ended June 30, 2019 and 2018 , the Board declared common share/unit dividends of $0.25 and $0.50 per common share/unit, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation We are involved from time-to-time in various legal proceedings that arise in the ordinary course of our business, including, but not limited to commercial disputes, environmental matters, and litigation in connection with transactions including acquisitions and divestitures. We believe that such litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated. Concentration of Credit Risk Our properties rely heavily upon anchor or major tenants to attract customers; however, these retailers do not constitute a material portion of our financial results. Additionally, many anchor retailers in the enclosed retail properties own their spaces further reducing their contribution to our operating results. All operations are within the United States and no customer or tenant accounts for 5% or more of our consolidated revenues. Lease Commitments As of June 30, 2019 , a total of four consolidated properties are subject to ground leases. The termination dates of these ground leases range from 2026 to 2076. These ground leases generally require us to make fixed annual rental payments, or a fixed annual rental plus a percentage rent component based upon the revenues or total sales of the property. Some of these leases also include escalation clauses and renewal options. For the three and six months ended June 30, 2019 , we incurred ground lease expense of $195 and $398 , respectively, of which $5 and $10 related to straight-line rent expense, respectively, which is included in ground rent in the accompanying consolidated statements of operations and comprehensive (loss) income. For the three and six months ended June 30, 2018 , we incurred ground lease expense of $198 and $395 , respectively, of which $12 and $25 related to straight-line rent expense, respectively. Additionally, the Company has two material office leases and one material garage lease. The termination dates of these leases range from 2023 to 2026. These leases generally require us to make fixed annual rental payments, plus our share of CAM expense and real estate taxes and insurance. For the three and six months ended June 30, 2019 , we incurred lease expense of $663 and $1,294 , respectively, which is included in general and administrative expenses in the accompanying consolidated statements of operations and comprehensive (loss) income. For the three and six months ended June 30, 2018 , we incurred lease expense of $576 and $1,409 , respectively. On January 1, 2019, we recorded a lease liability and corresponding ROU asset of approximately $14.4 million . The weighted average remaining lease term for our consolidated operating leases was 18.5 years and the weighted average discount rate for determining the lease liabilities was 8.7% at January 1, 2019. The discount rates utilized in calculating the lease liabilities represents our estimate of the Company's incremental borrowing rate over the terms that correspond to the leases. Future minimum lease payments due under these leases for each of the next five years and thereafter, excluding applicable extension options, as of June 30, 2019 are as follows: 2019 $ 1,016 2020 2,049 2021 2,069 2022 2,099 2023 1,427 Thereafter 21,377 Total lease payments 30,037 Less: Discount 16,374 Present value of lease liabilities $ 13,663 The weighted average remaining lease term for our consolidated operating leases was 18.8 years and the weighted average discount rate for determining the lease liabilities was 8.7% at June 30, 2019 . We had no financing leases as of June 30, 2019 .

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On July 1, 2019 , an affiliate of WPG Inc. transferred title of Towne West Square to the mortgage lender pursuant to the terms of a deed-in-lieu of foreclosure agreement entered into by the WPG Inc.'s affiliate and the mortgage lender concerning the $45.2 million mortgage loan. The Company will record a gain between $35.0 million and $40.0 million related to this debt extinguishment during the third quarter of 2019. On July 23, 2019 , the Company executed a separate purchase and sale agreement with Four Corners to sell the fee interest or leasehold interest in 20 additional outparcels for a purchase price of approximately $37.8 million . The Company expects to close on the majority of these parcels in 2020, subject to due diligence and closing conditions. On July 24, 2019 , the Company signed a definitive agreement for the sale and leaseback of four assets (collectively, the "Properties"). The Properties are: Edison Mall, located in Fort Myers, Florida; Great Lakes Mall, located in Mentor, Ohio; Irving Mall, located in Irving, Texas; and Jefferson Valley Mall, located in Yorktown Heights, New York. Under the agreement, a joint venture between Perennial Investments & Advisors, LLC and Kawa Capital Partners, institutional fee investors, will acquire a fee interest in the land at the Properties for a price of approximately $98.9 million . Concurrently, the Company will enter into a new 99 -year master ground lease for the leasehold interest at the Properties. The Company will continue to own a fee interest in the improvements through the term of the aforementioned master ground lease and continue to manage, lease and develop the Properties and maintain full control over the leasehold interest in the land and fee interest in the improvements at the respective Properties. The master ground lease includes fixed annual payments to the ground lessor at an initial annualized rate of 7.4% and contains annual rent escalators over the term. The agreement includes an option for the Company to repurchase the fee interest in the land at a fixed price in year 30 of the master ground lease. For accounting purposes, the repurchase option will preclude the Company from meeting the criteria for sales recognition. As such, the proceeds received will be accounted for as a financial liability during the term of the option.

Accounting Policies [Abstract]
Fair Value Measurements	Fair Value Measurements The Company measures and discloses its fair value measurements in accordance with Accounting Standards Codification ("ASC") Topic 820 - “Fair Value Measurement” (“Topic 820”). The fair value hierarchy, as defined by Topic 820, contains three levels of inputs that may be used to measure fair value as follows: • Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. • Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly, such as interest rates, foreign exchange rates, and yield curves, that are observable at commonly quoted intervals. • Level 3 inputs are unobservable inputs for the asset or liability which are typically based on an entity's own assumptions, as there is little, if any, related market activity. The asset or liability's fair value within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Under Topic 820, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction at the measurement date and under current market conditions.
Use of Estimates	Use of Estimates
Segment Disclosure	Segment Disclosure Our primary business is the ownership, development and management of retail real estate. We have aggregated our operations, including enclosed retail properties and open air properties, into one reportable segment because they have similar economic characteristics and we provide similar products and services to similar types of, and in many cases, the same tenants.
New Accounting Pronouncements	New Accounting Pronouncements Adoption of New Standards In February 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-02, "Leases (Topic 842)." This new guidance, including related ASUs that were subsequently issued, was effective January 1, 2019 and required lessees to recognize a lease liability and right of use ("ROU") asset, measured as the present value of lease payments, for both operating and financing leases with a term greater than 12 months. Additionally, the new standard made targeted changes to lessor accounting. The new leases standard required a modified retrospective transition approach for all leases existing at, or entered into after, January 1, 2017, with an option to use certain transition relief which allowed an entity to account for the impact of the adoption ASU 2016-02 with a cumulative adjustment to retained earnings, if necessary, on January 1, 2019, rather than January 1, 2017, eliminating the need to restate amounts presented prior to January 1, 2019. The Company adopted the new standard on January 1, 2019 and applied the new guidance utilizing the optional transition method noted above. The Company elected to use the "package of practical expedients," which allowed the Company not to reassess under the new standard prior conclusions about lease identification, lease classification, and initial direct costs. The Company did not make any adjustments to the opening balance of retained earnings upon adoption of the new standard given the nature of the impacts and other transition practical expedients elected by the Company. Upon adoption, the Company recognized a lease liability and corresponding ROU asset of approximately $14.4 million for the four material ground leases, two material office leases, and one material garage lease with a term of more than 12 months. For leases with a term of 12 months or less, the Company made an accounting policy election by underlying asset to not recognize lease liabilities and ROU assets. Additionally, the Company excluded certain office equipment leases due to materiality. All of these leases were classified as operating leases under legacy GAAP and the current classification was carried forward under ASU 2016-02. See "Note 10 - Commitments and Contingencies" for additional details. From a lessor perspective, the new guidance remained mostly similar to legacy GAAP as the Company elected the practical expedient to not separate non-lease components from lease components. This election resulted in a change on the Company's consolidated statements of operations and comprehensive (loss) income as the Company no longer presents minimum rents, overage rents, and tenant reimbursements as separate line items because the Company now accounts for these line items as a single combined lease component, rental income, on the basis of the lease component being the predominant component of the contract. As such, non-lease components, including common-area ("CAM") revenues, are now combined with lease components and are recognized on a straight-line basis to the extent the non-lease components are fixed. Additionally, ASU 2016-02 required the Company to recognize a change, after the commencement date, in their assessment of whether the collectibility of an operating lease receivable as probable as an adjustment to rental income rather than as a provision for credit losses. This requirement resulted in a change on the Company's consolidated statements of operations and comprehensive (loss) income as the Company no longer presents provision for credit losses as a separate line item and the adjustment is now recorded as a reduction to rental income. ASU 2016-02 also introduced certain changes to the lease classification rules for lessors. Accordingly, some leases may be classified as sales-type leases in the future. This change is not expected to have a material impact on the Company's financial statements. Finally, ASU 2016-02 disallowed the capitalization of internal leasing costs and legal costs, unless said costs are incremental to obtaining the lease contract, resulting in an increase in the Company's general and administrative expenses. For the three and six months ended June 30, 2018 , we capitalized approximately $4.6 million and $8.7 million of internal legal and leasing costs, respectively, that would no longer qualify for capitalization under the new standard. The Company elected to use the practical expedient in transition to not re-evaluate costs that were previously capitalized. New Standards Issued But Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, "Fair Value Measurements (ASC 820): Disclosure Framework- Changes to the Disclosure Requirements for Fair Value Measurements." ASU 2018-13 eliminates certain disclosure requirements for all entities, requires public entities to disclose certain new information, and modifies some disclosure requirements. ASU 2018-13 is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. We are currently evaluating the impact this ASU will have, if any, on our financial statements and related disclosures.
Reclassifications	Reclassifications Reclassifications were made to conform prior periods to our presentation of the consolidated statements of operations and comprehensive (loss) income due to the impact of adopting ASU 2016-02. Amounts previously disclosed as minimum rent, tenant reimbursements, and overage rent during the three and six months ended June 30, 2018
Lessor, Leases	We receive rental income from the leasing of retail and other space under operating leases, as we retain substantially all of the risks and benefits of ownership of the investment properties. The majority of these leases contain extension options, typically at the lessee's election, and/or early termination provisions. Further, our leases do not contain any provisions that would allow the lessee to purchase the underlying assets throughout the lease term. In most cases, consideration received typically includes a fixed minimum rent component, reimbursement of a fixed portion of our property operating expenses, including utility, security, janitorial, landscaping, food court and other administrative expenses (also known as CAM), and reimbursement of lessor costs such as real estate taxes and insurance, computed based upon a formula in accordance with the lease terms. When not reimbursed by the fixed CAM component, CAM expense reimbursements and lessor costs are based on the tenant's proportionate share of the allocable operating expenses and CAM capital expenditures for the property. We accrue reimbursements from tenants for recoverable portions of all these expenses as revenue in the period the applicable expenditures are incurred. We recognize differences between estimated recoveries and the final billed amounts in the subsequent year. Additionally, a large number of our tenants are also required to pay overage rents based on sales during the applicable lease year over a base amount stated in the lease agreement. We recognize overage rents only when each tenant's sales exceed the applicable sales threshold as defined in their lease. We also collect lease termination income from tenants to allow for the tenant to vacate their space prior to their scheduled lease termination date. We recognize lease termination income in the period when a termination agreement is signed, collectability is assured, and we are no longer obligated to provide space to the tenant. In the event that a tenant is in bankruptcy when the termination agreement is signed, termination fee income is deferred and recognized when, and if, it is received. We record an adjustment to rental income in the period there is a change in our assessment of whether the collectibility of an operating lease receivable is probable. We have elected the practical expedient in ASU 2016-02 to not separate non-lease components from lease components as our underlying leases qualify as operating leases and the timing and pattern of transfer of the lease and non-lease components are the same. We note that the predominant component of our leases is the lease component and thus account for the combined lease and non-lease component of the non-cancelable lease term on a straight-line basis in accordance with ASC 842. Rental income also includes accretion related to above-market and below-market lease intangibles related to the acquisition of operating properties. We amortize any tenant inducements as a reduction of rental income utilizing the straight-line method over the term of the related lease or occupancy term of the tenant, if shorter.
