Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Business Weingarten Realty Investors is a real estate investment trust (“REIT”) organized under the Texas Business Organizations Code. We currently operate, and intend to operate in the future, as a REIT. We, and our predecessor entity, began the ownership of shopping centers and other commercial real estate in 1948 . Our primary business is leasing space to tenants in the shopping centers we own or lease. We also provide property management services for which we charge fees to either joint ventures where we are partners or other outside owners. We operate a portfolio of neighborhood and community shopping centers, totaling approximately 39.5 million square feet of gross leaseable area, that is either owned by us or others. We have a diversified tenant base, with our largest tenant comprising only 2.7% of base minimum rental revenues during the first three months of 2018 . Total revenues generated by our centers located in Houston and its surrounding areas was 19.2% of total revenue for the three months ended March 31, 2018 , and an additional 9.0% of total revenue was generated during this period from centers that are located in other parts of Texas. Also, in Florida and California, an additional 18.5% and 16.8% , respectively, of total revenue was generated in during the first three months of 2018 . Basis of Presentation Our condensed consolidated financial statements include the accounts of our subsidiaries, certain partially owned real estate joint ventures or partnerships and variable interest entities (“VIEs”) which meet the guidelines for consolidation. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements included in this report are unaudited; however, amounts presented in the condensed consolidated balance sheet as of December 31, 2017 are derived from our audited financial statements at that date. In our opinion, all adjustments necessary for a fair presentation of such financial statements have been included. Such adjustments consisted of normal recurring items. Interim results are not necessarily indicative of results for a full year. The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and certain information included in our annual financial statements and notes thereto has been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and related notes for the year ended December 31, 2017 . Our financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Such statements require 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. Actual results could differ from these estimates. We have evaluated subsequent events for recognition or disclosure in our condensed consolidated financial statements. Revenue Recognition Rentals, net Rental revenue is generally recognized on a straight-line basis over the term of the lease, which generally begins the date the tenant takes control of the space. Revenue from tenant reimbursements of taxes, maintenance expenses and insurance is subject to our interpretation of lease provisions and is recognized in the period the related expense is recognized. Both of these revenues have been recognized under Accounting Standards Codification No. 840, “Leases.” Revenue based on a percentage of tenants’ sales is recognized only after the tenant exceeds their sales breakpoint. In circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease. Other Other revenue consists of both customer contract revenue and income from contractual agreements with third parties, tenants or partially owned real estate joint ventures or partnerships, which do not meet the definition of a lease or a customer contract. Revenues which do not meet the definition of a lease or customer contract are recognized as the related services are performed under the respective agreements. We have identified primarily three types of customer contract revenue; (1) management contracts with partially-owned real estate joint ventures or partnerships or third parties, (2) licensing and occupancy agreements and (3) certain non-tenant contracts. At contract inception, we assess the services provided in these contracts and identify any performance obligations that are distinct. To identify the performance obligation, we consider all services whether explicitly stated or implied by customary business practices. We have identified the following substantive services, which may or may not be included in each contract type, that represent performance obligations: Contract Type Performance Obligation Description Elements of Performance Obligations Payment Timing Management Agreements • Management and asset management services • Over time Typically monthly or quarterly • Leasing and legal preparation services • Point in time Licensing and Occupancy Agreements • Rent of non-specific space • Over time Typically monthly • Set-up services • Point in time Non-tenant Contracts • Placement of miscellaneous items at our centers that do not qualify as a lease, i.e. advertisements, trash bins, etc. • Point in time Typically monthly • Set-up services • Point in time We also assess collectability of the customer contract revenue prior to recognition. None of these customer contracts include a significant financing component. Customer contract revenue for the three months ended March 31, 2018 does not include any amounts that were from obligations satisfied (or partially satisfied) in prior periods, or was a contract liability at January 1, 2018. Accrued Rent, Accrued Contract Receivables and Accounts Receivable, net Receivables include base rents, tenant reimbursements, amounts billed and currently due from customer contracts and receivables attributable to straight-line rental commitments. Accrued contract receivables includes amounts due from customers for contracts that do not qualify as a lease in which we earned the right to the consideration through the satisfaction of the performance obligation, but before the customer pays consideration or before payment is due. An allowance for the uncollectible portion of accrued rents and accounts receivable is determined based upon an analysis of balances outstanding, historical bad debt levels, tenant creditworthiness and current economic trends. Additionally, estimates of the expected recovery of pre-petition and post-petition claims with respect to tenants in bankruptcy are considered in assessing the collectability of the related receivables. Management’s estimate of the collectability of accrued rents and accounts receivable is based on the best information available to management at the time of evaluation. Sales of Real Estate Sales of real estate include the sale of tracts of land within a shopping center development, property adjacent to shopping centers, operating properties, newly developed properties, investments in real estate joint ventures and partnerships and partial sales to real estate joint ventures and partnerships in which we participate. These sales primarily fall under two types of contracts (1) sales of nonfinancial assets and (2) sales of investments in real estate joint ventures and partnerships. We review the sale contract to determine appropriate accounting guidance. Profits on sales of real estate are primarily not recognized until (a) a contract exists including: each party’s rights are identifiable along with the payment terms, the contract has commercial substance and the collection of consideration is probable; and (b) the performance obligation to transfer control of the asset has occurred; including transfer to the buyer of the usual risks and rewards of ownership. We recognize gains on the sale of real estate to joint ventures and partnerships in which we participate to the extent we receive cash from the joint venture or partnership, if it meets the sales criteria in accordance with GAAP. Impairment Our property is reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the property, including any capitalized costs and any identifiable intangible assets, may not be recoverable. If such an event occurs, a comparison is made of the current and projected operating cash flows of each such property into the foreseeable future, with consideration of applicable holding periods, on an undiscounted basis to the carrying amount of such property. If we determine the carrying amount is not recoverable, our basis in the property is reduced to its estimated fair value to reflect impairment in the value of the asset. Fair values are determined by management utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker or appraisal estimates in accordance with our fair value measurements accounting policy. We review economic considerations at each reporting period, including the effects of tenant bankruptcies, the suspension of tenant expansion plans for new development projects, declines in real estate values, and any changes to plans related to our new development properties including land held for development, to identify properties where we believe market values may be deteriorating. Determining whether a property is impaired and, if impaired, the amount of write-down to fair value requires a significant amount of judgment by management and is based on the best information available to management at the time of evaluation. If market conditions deteriorate or management’s plans for certain properties change, additional write-downs could be required in the future. Our investment in partially owned real estate joint ventures and partnerships is reviewed for impairment each reporting period. The ultimate realization is dependent on a number of factors, including the performance of each investment and market conditions. We will record an impairment charge if we determine that a decline in the estimated fair value of an investment below its carrying amount is other than temporary. There is no certainty that impairments will not occur in the future if market conditions decline or if management’s plans for these investments change. Our investments in tax increment revenue bonds are reviewed for impairment, including the evaluation of changes in events or circumstances that may indicate that the carrying amount of the investment may not be recoverable. Realization is dependent on a number of factors, including investment performance, market conditions and payment structure. We will record an impairment charge if we determine that a decline in the value of the investment below its carrying amount is other than temporary, recovery of its cost basis is uncertain, and/or it is uncertain if the investment will be held to maturity. Accrued contract receivables are reviewed for impairment based on changes in events or circumstances effecting our customers that may indicate that the carrying value of the asset may not be recoverable. An impairment charge will be recorded if we determine that the decline in the asset value is other than temporary or recovery of the cost basis is uncertain. Factors to be considered include current economic trends such as bankruptcy and market conditions affecting our investments in partially owned real estate joint ventures and partnerships. Restricted Deposits and Mortgage Escrows Restricted deposits and mortgage escrows consist of escrow deposits held by lenders primarily for property taxes, insurance and replacement reserves and restricted deposits that are held for a specific use or in a qualified escrow account for the purposes of completing like-kind exchange transactions. Our restricted deposits and mortgage escrows consist of the following (in thousands): March 31, December 31, Restricted deposits $ 6,474 $ 6,291 Mortgage escrows 921 1,824 Total $ 7,395 $ 8,115 Accumulated Other Comprehensive Loss Changes in accumulated other comprehensive loss by component consists of the following (in thousands): Gain on Investments Gain on Cash Flow Hedges Defined Benefit Pension Plan-Actuarial Loss Total Balance, December 31, 2017 $ (1,541 ) $ (7,424 ) $ 15,135 $ 6,170 Cumulative effect adjustment of accounting standards (see Note 2) 1,541 1,541 Change excluding amounts reclassified from accumulated other comprehensive loss (1,379 ) (1,379 ) Amounts reclassified from accumulated other comprehensive loss 3,633 (1) (271 ) (2) 3,362 Net other comprehensive loss (income) — 2,254 (271 ) 1,983 Balance, March 31, 2018 $ — $ (5,170 ) $ 14,864 $ 9,694 Gain on Investments Gain on Cash Flow Hedges Defined Benefit Pension Plan-Actuarial Loss Total Balance, December 31, 2016 $ (964 ) $ (6,403 ) $ 16,528 $ 9,161 Change excluding amounts reclassified from accumulated other comprehensive loss (298 ) (389 ) (687 ) Amounts reclassified from accumulated other comprehensive loss (139 ) (1) (377 ) (2) (516 ) Net other comprehensive income (298 ) (528 ) (377 ) (1,203 ) Balance, March 31, 2017 $ (1,262 ) $ (6,931 ) $ 16,151 $ 7,958 _______________ (1) This reclassification component is included in interest expense (see Note 6 for additional information). (2) This reclassification component is included in th e computation of net periodic benefit cost (see Note 12 for additional information). Retrospective Application of Accounting Standard Update The retrospective application of adopting Accounting Standard Update ("ASU") No. 2017-07, "Improving the Presentation of Net Periodic Pensions Cost and Net Periodic Postretirement Benefit Cost" on prior year's Condensed Consolidated Statements of Operations was made to conform to the current year presentation (see Note 2 for additional information). Also, the retrospective application of adopting ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments" and ASU No. 2016-18, "Restricted Cash" as of December 31, 2017 on prior year's Condensed Consolidated Statement of Cash Flows was made to conform to the current year presentation. The adoption of these ASUs in the Condensed Consolidated Statement of Cash Flow for the three months ended March 31, 2017 , resulted in a retrospective reclassification of $2.7 million from cash flows from investing activities to cash flows from operating activities, and cash flows from investing activities no longer reflect the change in restricted deposits and mortgage escrows totaling $21.9 million .

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Newly Issued Accounting Pronouncements	Newly Issued Accounting Pronouncements Adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers." This ASU's core objective is for an entity to recognize revenue based on the consideration it expects to receive in exchange for goods or services. Additionally, this ASU requires entities to use a single model in accounting for revenues derived from contracts with customers. ASU No. 2014-09 replaces prior guidance regarding the recognition of revenue from sales of real estate, except for revenue from sales that are part of a sale-leaseback transaction. The provisions of ASU No. 2014-09, as amended in subsequently issued amendments, were effective for us on January 1, 2018. We adopted this guidance as of January 1, 2018 and applied it on a modified retrospective approach upon adoption. The adoption resulted in the identification of primarily three types of customer contracts: (1) management contracts with partially owned real estate joint ventures or partnerships or third parties, (2) licensing and occupancy agreements and (3) certain non-tenant contracts. We will continue to recognize these fees as we currently do with the exception of the timing associated with the performance obligation in our management contracts related to leasing and lease preparation related services. Upon adoption, we recognized the cumulative effect for these fees which has increased retained earnings and accrued rent, accrued contract receivables and accounts receivable, net by $.3 million , respectively. In addition, we evaluated controls around the implementation of this ASU and have concluded there was no significant impact on our control structure. We have included our customer contract revenues under the caption Other revenues in the Condensed Consolidated Statements of Operations and have expanded our disclosures related to this ASU in Note 1. In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU will require equity investments, excluding those investments accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income; will simplify the impairment assessment of those investments; will eliminate the disclosure of the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost and change the fair value calculation for those investments; will change the disclosure in other comprehensive income for financial liabilities that are measured at fair value in accordance with the fair value options for financial instruments; and will clarify that a deferred asset related to available-for-sale securities should be included in an entity's evaluation for a valuation allowance. The provisions of ASU No. 2016-01 were effective for us as of January 1, 2018 and are required to be applied on a modified retrospective approach. Upon adoption, we recognized the cumulative effect for the fair value of equity investments which has increased retained earnings and accumulated other comprehensive loss each by $1.5 million and includes the effects of ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." In February 2017, the FASB issued ASU No. 2017-05, "Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The ASU clarifies that a financial asset is within the scope of Subtopic 610-20 if it meets the definition, as amended, of an in substance nonfinancial asset. If substantially all of the fair value of assets that are promised to a counterparty in a contract is concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of Subtopic 610-20, including a parent transferring control of a nonfinancial asset through a transfer of ownership interests of a consolidated subsidiary. The provisions of ASU No. 2017-05 were effective for us as of January 1, 2018 and depending on the contract type may be recorded on a retrospective or modified retrospective approach. As a result of our contract analysis under ASU 2014-09, the majority of our contracts relate to property sales to be accounted for under this ASU and could result in future gains being recognized sooner. Upon adoption, we applied the modified retrospective approach for all contract types and for contracts considered not completed. We recognized the cumulative effect for in substance nonfinancial assets in which gains would have been realized and have increased each of retained earnings and other assets by $3.6 million at January 1, 2018. In March 2017, the FASB issued ASU No. 2017-07, "Improving the Presentation of Net Periodic Pensions Cost and Net Periodic Postretirement Benefit Cost." The ASU requires the service cost component to be reported as compensation costs arising from services rendered by pertinent employees during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component and outside income from operations. Additionally, only the service cost component will be eligible for capitalization when applicable. The provisions of ASU No. 2017-07 were effective for us as of January 1, 2018 on a retrospective basis for the presentation within the income statement and prospectively for the capitalization of costs. The adoption of this ASU did not have a material impact to our consolidated financial statements. We have elected to use the practical expedient in determining estimates for applying the retrospective presentation requirements. For the three months ended March 31, 2017 , net periodic benefit cost, excluding the service cost component, of $.1 million , was included in Interest and Other Income/Expense in our Condensed Consolidated Statements of Operations. For the year ended December 31, 2017 , net periodic benefit cost, excluding the service cost component, was $.4 million . In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities." The ASU amends current hedge accounting recognition and presentation requirements. Items focused on include: alignment of an entity’s risk management activities and its financial reporting for hedging relationships, the use of hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risk, updates for designating fair value hedges of interest rate risk and measuring the related change in fair value of the hedged item, alignment of the recognition and presentation of the effects of the hedging instrument and the hedged item, and permits an entity to exclude certain amounts related to currency swaps. Lastly, the ASU also provides additional relief on effectiveness testing methods and disclosures. The provisions of ASU No. 2017-12 are effective for us as of January 1, 2019, and early adoption is permitted. We have adopted this ASU as of January 1, 2018, which required the modified retrospective transition method upon adoption. The adoption of this ASU did not have a material impact to our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." ASU No. 2018-02 allows for the reclassification of the stranded tax effects resulting from the Tax Cuts and Jobs Act to retained earnings. The provisions of ASU No. 2018-02 are effective for us as of January 1, 2019, may be applied either at the beginning of the period of adoption or retrospectively, and early adoption is permitted. We adopted this ASU along with the adoption of ASU No. 2016-01 on January 1, 2018. Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, "Leases." The ASU sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessees to adopt a right-of-use asset approach that will bring substantially all leases onto the balance sheet, with the exception of short-term leases. The subsequent accounting for this right-of-use asset will be based on a dual-model approach, under which the lease will be classified as either a finance or an operating lease. The lessor accounting model under this ASU is similar to current guidance, but certain underlying principles in the lessor model have been aligned with the new revenue recognition standard. This ASU was further updated by ASU 2018-01, "Land Easement Practical Expedient for Transition for Topic 842." The provisions of these ASUs are effective for us as of January 1, 2019, are required to be applied on a modified retrospective approach and early adoption is permitted. In January 2018, the FASB issued an exposure draft ("2018 Exposure Draft") which, if adopted as written, would allow lessors a practical expedient by class of underlying assets to account for lease and non-lease components as a single lease component if certain criteria are met. Also, the 2018 Exposure Draft indicates that companies may be permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of the modified retrospective approach and provides other optional practical expedients. We are in the process of evaluating the impact to our 5,200 lessor leases and other lessee leases, if any, that the adoption of this ASU will have on our consolidated financial statements. Within our lessor leases, we are entitled to receive tenant reimbursements for operating expenses such as real estate taxes, insurance and common area maintenance (“CAM”). Currently upon adoption of this ASU, CAM reimbursement revenue will be accounted for in accordance with Topic 606 (ASU No. 2014-09 as discussed above). We have currently identified some areas we believe may be impacted by this ASU. These include: • The bifurcation of lease arrangements in which contractual amounts due are on a gross basis and the amount under contract is not allocated between rental and expense reimbursements, such as real estate taxes and insurance. This process would be based on the underlying fair values of these items. • We have ground lease agreements in which we are the lessee for land underneath all or a portion of 13 centers and three administrative office leases that we account for as operating leases. Rental expense associated with these operating leases for the three months ended March 31, 2018 and 2017 was $.7 million and $.8 million , respectively. We have one capital lease in which we are the lessee of two centers with a $21 million lease obligation. We will record any rights and obligations under these leases as an asset and liability at fair value in our consolidated balance sheets. • Determination of costs to be capitalized associated with leases. This ASU will limit the capitalization associated with certain costs, primarily certain internally-generated leasing and legal costs, of which we capitalized internal costs of $2.5 million for the three months ended March 31, 2018 , and $10.8 million for the year ended December 31, 2017 . We believe we will be able to continue to capitalize internal leasing commissions that are a direct result of obtaining a lease. In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments." This ASU amends prior guidance on the impairment of financial instruments, and adds an impairment model that is based on expected losses rather than incurred losses with the recognition of an allowance based on an estimate of expected credit losses. The provisions of ASU No. 2016-13 are effective for us as of January 1, 2020, and early adoption is permitted for fiscal years beginning after December 15, 2018. We are currently assessing the impact, if any, that the adoption of this ASU will have on our consolidated financial statements.

Equity Method Investments and Joint Ventures [Abstract]
Investment In Real Estate Joint Ventures And Partnerships	Investment in Real Estate Joint Ventures and Partnerships We own interests in real estate joint ventures or limited partnerships and have tenancy-in-common interests in which we exercise significant influence, but do not have financial and operating control. We account for these investments using the equity method, and our interests ranged for the periods presented from 20% to 90% in 2018 and 2017. Combined condensed financial information of these ventures (at 100%) is summarized as follows (in thousands): March 31, December 31, Combined Condensed Balance Sheets ASSETS Property $ 1,244,419 $ 1,241,004 Accumulated depreciation (290,227 ) (285,033 ) Property, net 954,192 955,971 Other assets, net 112,772 115,743 Total Assets $ 1,066,964 $ 1,071,714 LIABILITIES AND EQUITY Debt, net (primarily mortgages payable) $ 286,259 $ 298,124 Amounts payable to Weingarten Realty Investors and Affiliates 12,005 12,017 Other liabilities, net 23,320 24,759 Total Liabilities 321,584 334,900 Equity 745,380 736,814 Total Liabilities and Equity $ 1,066,964 $ 1,071,714 Three Months Ended 2018 2017 Combined Condensed Statements of Operations Revenues, net $ 33,886 $ 34,738 Expenses: Depreciation and amortization 8,043 9,013 Interest, net 3,524 2,967 Operating 6,428 6,118 Real estate taxes, net 4,942 4,268 General and administrative 225 368 Provision for income taxes 36 7 Total 23,198 22,741 Gain on dispositions 3,533 — Net income $ 14,221 $ 11,997 Our investment in real estate joint ventures and partnerships, as reported in our Condensed Consolidated Balance Sheets, differs from our proportionate share of the entities' underlying net assets due to basis differences, which arose upon the transfer of assets to the joint ventures. The net positive basis differences, which totaled $3.4 million and $2.2 million at March 31, 2018 and December 31, 2017 , respectively, are generally amortized over the useful lives of the related assets. Fees earned by us for the management of these real estate joint ventures and partnerships included in Other Revenue totaled $1.5 million for both the three months ended March 31, 2018 and 2017 . For the three months ended March 31, 2018 , there was a partial sale of a center for gross sales proceeds of approximately $11.7 million , of which our share of the gain, included in equity earnings in real estate joint ventures and partnerships, totaled $2.4 million . During 2017, two centers were sold with aggregate gross sales proceeds of approximately $ 19.6 million , of which our share of the gain, included in equity earnings in real estate joint ventures and partnerships, totaled $6.2 million . In June 2017, a venture acquired land with a gross purchase price of $23.5 million for a mixed-use development project, and we simultaneously increased our ownership interest to 90% (See Note 15 for additional information).

This facility expires in March 2020 , provides for two consecutive six -month extensions upon our request, and borrowing rates that float at a margin over LIBOR plus a facility fee. At both March 31, 2018 and December 31, 2017 , the borrowing margin and facility fee, which are priced off a grid that is tied to our senior unsecured credit ratings, were 90 and 15 basis points, respectively. The facility also contains a competitive bid feature that allows us to request bids for up to $250 million . Additionally, an accordion feature allows us to increase the facility amount up to $850 million . Additionally, we have a $10 million unsecured short-term facility, which was amended and extended on March 27, 2018 , that we maintain for cash management purposes, which matures in March 2019 . At both March 31, 2018 and December 31, 2017 , the facility provided for fixed interest rate loans at a 30 -day LIBOR rate plus a borrowing margin, facility fee and an unused facility fee of 125 , 10 , and 5 basis points, respectively.

The bonds are to be repaid with incremental sales and property taxes and a public improvement fee (“PIF”) to be assessed on current and future retail sales and, to the extent necessary, any amounts we may have to provide under a guaranty. The incremental taxes and PIF are to remain intact until the earlier of the date the bond liability has been paid in full or 2040. Therefore, a debt service guaranty liability equal to the fair value of the amounts funded under the bonds was recorded. As of both March 31, 2018 and December 31, 2017 , we had $64.1 million outstanding for the debt service guaranty liability. During March 2018, we prepaid $100 million of our $200 million unsecured variable-rate term loan, swapped to a fixed rate of 2.5% , and terminated the associated interest rate swap contracts (see Note 6 for additional information). Additionally during the three months ended March 31, 2018 , we paid at par $50.3 million of outstanding debt. These transactions resulted in a net gain upon their extinguishment of $.4 million . Subsequent to March 31, 2018, we prepaid, without penalty, the remaining $100 million of our $200 million unsecured term loan and repurchased $.6 million in other outstanding debt. Various leases and properties, and current and future rentals from those leases and properties, collateralize certain debt. At March 31, 2018 and December 31, 2017 , the carrying value of such assets aggregated $.6 billion and $.7 billion , respectively. Additionally, investments of $4.5 million are held as collateral for letters of credit totaling $4.3 million .

During the three months ended March 31, 2018 , associated with the prepayment of an unsecured note, we terminated three interest rate swap contracts that had an aggregate notional amount of $200 million , and we recognized a $3.4 million gain due to the probability that the related hedged forecasted transactions would no longer occur. As of December 31, 2017 , we had three interest rate swap contracts, maturing through March 1, 2020 , with an aggregate notional amount of $200 million that were designated as cash flow hedges and fixed the LIBOR component of the interest rates at 1.5% . As of March 31, 2018 and December 31, 2017 , the net gain balance in accumulated other comprehensive loss relating to previously terminated cash flow interest rate swap contracts was $5.2 million and $7.4 million , respectively, which will be reclassified to net interest expense as interest payments are made on the originally hedged debt. Within the next 12 months, approximately $.9 million in accumulated other comprehensive loss is expected to be reclassified as a reduction to interest expense related to our interest rate contracts.

Share Options and Awards	Share Options and Awards During 2018 , we granted share awards incorporating both service-based and market-based measures to promote share ownership among the participants and to emphasize the importance of total shareholder return ("TSR"). The terms of each grant vary depending upon the participant's responsibilities and position within the Company. We categorize these share awards as either service-based share awards or market-based share awards. All awards were valued at the fair market value on the date of grant and earn dividends from the date of grant. Compensation expense is measured at the grant date and recognized over the vesting period. Generally, unvested share awards are forfeited upon the termination of the participant’s employment with us. The fair value of the market-based share awards was estimated on the date of grant using a Monte Carlo valuation model based on the following assumptions: Three Months Ended Minimum Maximum Dividend yield 0.0 % 5.5 % Expected volatility (1) 18.5 % 20.4 % Expected life (in years) N/A 3 Risk-free interest rate 1.8 % 2.4 % _______________ (1) Includes the volatility of the FTSE NAREIT U.S. Shopping Center Index and Weingarten Realty Investors.

We have operating and financial control over these ventures and consolidate them in our condensed consolidated financial statements. These ventures allow the outside limited partners to put their interest in the partnership to us, and we have the option to redeem the interest in cash or a fixed number of our common shares, at our discretion. We also participate in a real estate venture that has a property in Texas that allows its outside partner to put operating partnership units to us. We have the option to redeem these units in cash or a fixed number of our common shares, at our discretion. The aggregate redemption value of these interests was approximately $40 million and $47 million as of March 31, 2018 and December 31, 2017 , respectively. As of March 31, 2018 , we have entered into commitments aggregating $229.6 million comprised principally of construction contracts which are generally due in 12 to 36 months. Included in these commitments is our commitment under a contractor agreement for construction costs signed during the three months ended March 31, 2018 of $115.4 million for the 30-story, high-rise residential tower at our River Oaks Shopping Center. We issue letters of intent signifying a willingness to negotiate for acquisitions, dispositions or joint ventures, as well as other types of potential transactions, during the ordinary course of our business. Such letters of intent and other arrangements are non-binding to all parties unless and until a definitive contract is entered into by the parties. Even if definitive contracts relating to the acquisition or disposition of property are entered into, these contracts generally provide the purchaser a time period to evaluate the property and conduct due diligence. The purchaser, during this time, will have the ability to terminate a contract without penalty or forfeiture of any deposit or earnest money. No assurance can be provided that any definitive contracts will be entered into with respect to any matter covered by letters of intent, or that we will consummate any transaction contemplated by a definitive contract. Additionally, due diligence periods for property transactions are frequently extended as needed. An acquisition or disposition of property becomes probable at the time the due diligence period expires and the definitive contract has not been terminated. Our risk is then generally extended only to any earnest money deposits associated with property acquisition contracts, and our obligation to sell under a property sales contract. 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 condensed consolidated financial statements. As part of our risk management activities, we have applied and been accepted into state sponsored environmental programs which will limit our expenses if 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. Litigation We are involved in various matters of litigation arising in the normal course of business. While we are unable to predict the amounts involved, our management and counsel are of the opinion that, when such litigation is resolved, any additional liability, if any, will not have a material effect on our condensed consolidated financial statements.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities Consolidated VIEs: At both March 31, 2018 and December 31, 2017 , nine of our real estate joint ventures, whose activities primarily consisted of owning and operating 22 neighborhood/community shopping centers, were determined to be VIEs. Based on a financing agreement by one of our real estate joint ventures that has a bottom dollar guaranty, which is disproportionate to our ownership, we have determined that we are the primary beneficiary and have consolidated this joint venture. For the remaining real estate joint ventures, we concluded we are the primary beneficiary based primarily on our significant power to direct the entities' activities without any substantive kick-out or participating rights. A summary of our consolidated VIEs is as follows (in thousands): March 31, December 31, Assets Held by VIEs $ 231,333 $ 235,713 Assets Held as Collateral for Debt (1) 41,942 42,979 Maximum Risk of Loss (1) 29,784 29,784 ___________________ (1) Represents the amount of debt and related assets held as collateral associated with the bottom dollar guaranty at one real estate joint venture. Restrictions on the use of these assets can be significant because they may serve as collateral for debt. Further, we are generally required to obtain our partner's approval in accordance with the joint venture agreement for any major transactions. Transactions with these joint ventures on our condensed consolidated financial statements have primarily been positive as demonstrated by the generation of net income and operating cash flows, as well as the receipt of cash distributions. We and our partners are subject to the provisions of the joint venture agreements which include provisions for when additional contributions may be required to fund operating cash shortfalls, development expenditures and unplanned capital expenditures. For the three months ended March 31, 2018 , $.1 million in additional contributions were made primarily to fund an operating shortfall, and no additional contributions are currently anticipated to be made during the remainder of 2018. Unconsolidated VIEs: At both March 31, 2018 and December 31, 2017 , two unconsolidated real estate joint ventures were determined to be VIEs. We have determined that one entity was a VIE through the issuance of a secured loan, since the lender had the ability to make decisions that could have a significant impact on the success of the entity. Based on the associated agreements for the future development of a mixed-use project, we concluded that the other entity was a VIE, but we are not the primary beneficiary as the substantive participating rights associated with the entity are shared, and we do not have the power to direct the significant activities of the entity. Our analysis considered that all major decisions require unanimous member consent and those decisions include significant activities such as development, financing, leasing and operations of the entity. A summary of our unconsolidated VIEs is as follows (in thousands): March 31, December 31, Investment in Real Estate Joint Ventures and Partnerships, net (1) $ 42,533 $ 36,784 Other Liabilities, net (2) 5,701 5,799 Maximum Risk of Loss (3) 34,000 34,000 ___________________ (1) The carrying amount of the investment represents our contributions to a real estate joint venture, net of any distributions made and our portion of the equity in earnings of the real estate joint venture. The increase between periods represents new development funding of a mixed-use project. (2) Includes the carrying amount of an investment where distributions have exceeded our contributions and our portion of the equity in earnings for a real estate joint venture. (3) The maximum risk of loss has been determined to be limited to our debt exposure for the real estate joint ventures. We and our partners are subject to the provisions of the joint venture agreements that specify conditions, including operating shortfalls, development expenditures and unplanned capital expenditures, under which additional contributions may be required. With respect to our future development of a mixed-used project, we anticipate funding approximately $89 million through 2020 .

In such an event, a comparison is made of the current and projected operating cash flows of each such property into the foreseeable future on an undiscounted basis to the carrying amount of such property. If we conclude that an impairment may have occurred, estimated fair values are determined by management utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker valuation estimates, appraisals, bona fide purchase offers or the expected sales price of an executed sales agreement in accordance with our fair value measurements accounting policy. Market capitalization rates and market discount rates are determined by reviewing current sales of similar properties and transactions, and utilizing management’s knowledge and expertise in property marketing. No assets were measured at fair value on a nonrecurring basis at March 31, 2018 . Assets measured at fair value on a nonrecurring basis at December 31, 2017 aggregated by the level in the fair value hierarchy in which those measurements fall, are as follows (in thousands): Quoted Prices Significant Significant Fair Value Total Gains (1) Property (2) $ 12,901 $ 4,184 $ 17,085 $ (7,828 ) Total $ — $ 12,901 $ 4,184 $ 17,085 $ (7,828 ) ____________ (1) Total gains (losses) exclude impairments on disposed assets because they are no longer held by us. (2) In accordance with our policy of evaluating and recording impairments on the disposal of long-lived assets, property with a carrying amount of $24.9 million was written down to a fair value of $17.1 million , resulting in a loss of $7.8 million , which was included in earnings for the first quarter of 2017. Management’s estimate of fair value of these properties was determined using a bona fide purchase offer for the Level 2 inputs. See the quantitative information about the significant unobservable inputs used for our Level 3 fair value measurements table below.

Summary of Significant Accoun26

Summary of Significant Accounting Policies (Policy)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our condensed consolidated financial statements include the accounts of our subsidiaries, certain partially owned real estate joint ventures or partnerships and variable interest entities (“VIEs”) which meet the guidelines for consolidation. All intercompany balances and transactions have been eliminated. The condensed consolidated financial statements included in this report are unaudited; however, amounts presented in the condensed consolidated balance sheet as of December 31, 2017 are derived from our audited financial statements at that date. In our opinion, all adjustments necessary for a fair presentation of such financial statements have been included. Such adjustments consisted of normal recurring items. Interim results are not necessarily indicative of results for a full year. The condensed consolidated financial statements and notes are presented as permitted by Form 10-Q and certain information included in our annual financial statements and notes thereto has been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and related notes for the year ended December 31, 2017 . Our financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Such statements require 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. Actual results could differ from these estimates. We have evaluated subsequent events for recognition or disclosure in our condensed consolidated financial statements.
Revenue Recognition	Revenue Recognition Rentals, net Rental revenue is generally recognized on a straight-line basis over the term of the lease, which generally begins the date the tenant takes control of the space. Revenue from tenant reimbursements of taxes, maintenance expenses and insurance is subject to our interpretation of lease provisions and is recognized in the period the related expense is recognized. Both of these revenues have been recognized under Accounting Standards Codification No. 840, “Leases.” Revenue based on a percentage of tenants’ sales is recognized only after the tenant exceeds their sales breakpoint. In circumstances where we provide a tenant improvement allowance for improvements that are owned by the tenant, we recognize the allowance as a reduction of rental revenue on a straight-line basis over the term of the lease. Other Other revenue consists of both customer contract revenue and income from contractual agreements with third parties, tenants or partially owned real estate joint ventures or partnerships, which do not meet the definition of a lease or a customer contract. Revenues which do not meet the definition of a lease or customer contract are recognized as the related services are performed under the respective agreements. We have identified primarily three types of customer contract revenue; (1) management contracts with partially-owned real estate joint ventures or partnerships or third parties, (2) licensing and occupancy agreements and (3) certain non-tenant contracts. At contract inception, we assess the services provided in these contracts and identify any performance obligations that are distinct. To identify the performance obligation, we consider all services whether explicitly stated or implied by customary business practices. We have identified the following substantive services, which may or may not be included in each contract type, that represent performance obligations: Contract Type Performance Obligation Description Elements of Performance Obligations Payment Timing Management Agreements • Management and asset management services • Over time Typically monthly or quarterly • Leasing and legal preparation services • Point in time Licensing and Occupancy Agreements • Rent of non-specific space • Over time Typically monthly • Set-up services • Point in time Non-tenant Contracts • Placement of miscellaneous items at our centers that do not qualify as a lease, i.e. advertisements, trash bins, etc. • Point in time Typically monthly • Set-up services • Point in time We also assess collectability of the customer contract revenue prior to recognition. None of these customer contracts include a significant financing component. Customer contract revenue for the three months ended March 31, 2018 does not include any amounts that were from obligations satisfied (or partially satisfied) in prior periods, or was a contract liability at January 1, 2018. Accrued Rent, Accrued Contract Receivables and Accounts Receivable, net Receivables include base rents, tenant reimbursements, amounts billed and currently due from customer contracts and receivables attributable to straight-line rental commitments. Accrued contract receivables includes amounts due from customers for contracts that do not qualify as a lease in which we earned the right to the consideration through the satisfaction of the performance obligation, but before the customer pays consideration or before payment is due. An allowance for the uncollectible portion of accrued rents and accounts receivable is determined based upon an analysis of balances outstanding, historical bad debt levels, tenant creditworthiness and current economic trends. Additionally, estimates of the expected recovery of pre-petition and post-petition claims with respect to tenants in bankruptcy are considered in assessing the collectability of the related receivables. Management’s estimate of the collectability of accrued rents and accounts receivable is based on the best information available to management at the time of evaluation.
Sales of Real Estate	Sales of Real Estate Sales of real estate include the sale of tracts of land within a shopping center development, property adjacent to shopping centers, operating properties, newly developed properties, investments in real estate joint ventures and partnerships and partial sales to real estate joint ventures and partnerships in which we participate. These sales primarily fall under two types of contracts (1) sales of nonfinancial assets and (2) sales of investments in real estate joint ventures and partnerships. We review the sale contract to determine appropriate accounting guidance. Profits on sales of real estate are primarily not recognized until (a) a contract exists including: each party’s rights are identifiable along with the payment terms, the contract has commercial substance and the collection of consideration is probable; and (b) the performance obligation to transfer control of the asset has occurred; including transfer to the buyer of the usual risks and rewards of ownership. We recognize gains on the sale of real estate to joint ventures and partnerships in which we participate to the extent we receive cash from the joint venture or partnership, if it meets the sales criteria in accordance with GAAP.
Impairment	Impairment Our property is reviewed for impairment if events or changes in circumstances indicate that the carrying amount of the property, including any capitalized costs and any identifiable intangible assets, may not be recoverable. If such an event occurs, a comparison is made of the current and projected operating cash flows of each such property into the foreseeable future, with consideration of applicable holding periods, on an undiscounted basis to the carrying amount of such property. If we determine the carrying amount is not recoverable, our basis in the property is reduced to its estimated fair value to reflect impairment in the value of the asset. Fair values are determined by management utilizing cash flow models, market capitalization rates and market discount rates, or by obtaining third-party broker or appraisal estimates in accordance with our fair value measurements accounting policy. We review economic considerations at each reporting period, including the effects of tenant bankruptcies, the suspension of tenant expansion plans for new development projects, declines in real estate values, and any changes to plans related to our new development properties including land held for development, to identify properties where we believe market values may be deteriorating. Determining whether a property is impaired and, if impaired, the amount of write-down to fair value requires a significant amount of judgment by management and is based on the best information available to management at the time of evaluation. If market conditions deteriorate or management’s plans for certain properties change, additional write-downs could be required in the future. Our investment in partially owned real estate joint ventures and partnerships is reviewed for impairment each reporting period. The ultimate realization is dependent on a number of factors, including the performance of each investment and market conditions. We will record an impairment charge if we determine that a decline in the estimated fair value of an investment below its carrying amount is other than temporary. There is no certainty that impairments will not occur in the future if market conditions decline or if management’s plans for these investments change. Our investments in tax increment revenue bonds are reviewed for impairment, including the evaluation of changes in events or circumstances that may indicate that the carrying amount of the investment may not be recoverable. Realization is dependent on a number of factors, including investment performance, market conditions and payment structure. We will record an impairment charge if we determine that a decline in the value of the investment below its carrying amount is other than temporary, recovery of its cost basis is uncertain, and/or it is uncertain if the investment will be held to maturity. Accrued contract receivables are reviewed for impairment based on changes in events or circumstances effecting our customers that may indicate that the carrying value of the asset may not be recoverable. An impairment charge will be recorded if we determine that the decline in the asset value is other than temporary or recovery of the cost basis is uncertain. Factors to be considered include current economic trends such as bankruptcy and market conditions affecting our investments in partially owned real estate joint ventures and partnerships.
Restricted Deposits And Mortgage Escrows	Restricted Deposits and Mortgage Escrows Restricted deposits and mortgage escrows consist of escrow deposits held by lenders primarily for property taxes, insurance and replacement reserves and restricted deposits that are held for a specific use or in a qualified escrow account for the purposes of completing like-kind exchange transactions.
Retrospective Application of Accounting Standard Update	Retrospective Application of Accounting Standard Update The retrospective application of adopting Accounting Standard Update ("ASU") No. 2017-07, "Improving the Presentation of Net Periodic Pensions Cost and Net Periodic Postretirement Benefit Cost" on prior year's Condensed Consolidated Statements of Operations was made to conform to the current year presentation (see Note 2 for additional information).
Newly Issued Accounting Pronouncements	Newly Issued Accounting Pronouncements Adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU No. 2014-09, "Revenue from Contracts with Customers." This ASU's core objective is for an entity to recognize revenue based on the consideration it expects to receive in exchange for goods or services. Additionally, this ASU requires entities to use a single model in accounting for revenues derived from contracts with customers. ASU No. 2014-09 replaces prior guidance regarding the recognition of revenue from sales of real estate, except for revenue from sales that are part of a sale-leaseback transaction. The provisions of ASU No. 2014-09, as amended in subsequently issued amendments, were effective for us on January 1, 2018. We adopted this guidance as of January 1, 2018 and applied it on a modified retrospective approach upon adoption. The adoption resulted in the identification of primarily three types of customer contracts: (1) management contracts with partially owned real estate joint ventures or partnerships or third parties, (2) licensing and occupancy agreements and (3) certain non-tenant contracts. We will continue to recognize these fees as we currently do with the exception of the timing associated with the performance obligation in our management contracts related to leasing and lease preparation related services. Upon adoption, we recognized the cumulative effect for these fees which has increased retained earnings and accrued rent, accrued contract receivables and accounts receivable, net by $.3 million , respectively. In addition, we evaluated controls around the implementation of this ASU and have concluded there was no significant impact on our control structure. We have included our customer contract revenues under the caption Other revenues in the Condensed Consolidated Statements of Operations and have expanded our disclosures related to this ASU in Note 1. In January 2016, the FASB issued ASU No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities." This ASU will require equity investments, excluding those investments accounted for under the equity method of accounting or those that result in consolidation of the investee, to be measured at fair value with the changes in fair value recognized in net income; will simplify the impairment assessment of those investments; will eliminate the disclosure of the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost and change the fair value calculation for those investments; will change the disclosure in other comprehensive income for financial liabilities that are measured at fair value in accordance with the fair value options for financial instruments; and will clarify that a deferred asset related to available-for-sale securities should be included in an entity's evaluation for a valuation allowance. The provisions of ASU No. 2016-01 were effective for us as of January 1, 2018 and are required to be applied on a modified retrospective approach. Upon adoption, we recognized the cumulative effect for the fair value of equity investments which has increased retained earnings and accumulated other comprehensive loss each by $1.5 million and includes the effects of ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." In February 2017, the FASB issued ASU No. 2017-05, "Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets." The ASU clarifies that a financial asset is within the scope of Subtopic 610-20 if it meets the definition, as amended, of an in substance nonfinancial asset. If substantially all of the fair value of assets that are promised to a counterparty in a contract is concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of Subtopic 610-20, including a parent transferring control of a nonfinancial asset through a transfer of ownership interests of a consolidated subsidiary. The provisions of ASU No. 2017-05 were effective for us as of January 1, 2018 and depending on the contract type may be recorded on a retrospective or modified retrospective approach. As a result of our contract analysis under ASU 2014-09, the majority of our contracts relate to property sales to be accounted for under this ASU and could result in future gains being recognized sooner. Upon adoption, we applied the modified retrospective approach for all contract types and for contracts considered not completed. We recognized the cumulative effect for in substance nonfinancial assets in which gains would have been realized and have increased each of retained earnings and other assets by $3.6 million at January 1, 2018. In March 2017, the FASB issued ASU No. 2017-07, "Improving the Presentation of Net Periodic Pensions Cost and Net Periodic Postretirement Benefit Cost." The ASU requires the service cost component to be reported as compensation costs arising from services rendered by pertinent employees during the period. The other components of net periodic benefit cost are required to be presented in the income statement separately from the service cost component and outside income from operations. Additionally, only the service cost component will be eligible for capitalization when applicable. The provisions of ASU No. 2017-07 were effective for us as of January 1, 2018 on a retrospective basis for the presentation within the income statement and prospectively for the capitalization of costs. The adoption of this ASU did not have a material impact to our consolidated financial statements. We have elected to use the practical expedient in determining estimates for applying the retrospective presentation requirements. For the three months ended March 31, 2017 , net periodic benefit cost, excluding the service cost component, of $.1 million , was included in Interest and Other Income/Expense in our Condensed Consolidated Statements of Operations. For the year ended December 31, 2017 , net periodic benefit cost, excluding the service cost component, was $.4 million . In August 2017, the FASB issued ASU No. 2017-12, "Derivatives and Hedging - Targeted Improvements to Accounting for Hedging Activities." The ASU amends current hedge accounting recognition and presentation requirements. Items focused on include: alignment of an entity’s risk management activities and its financial reporting for hedging relationships, the use of hedge accounting for risk components in hedging relationships involving nonfinancial risk and interest rate risk, updates for designating fair value hedges of interest rate risk and measuring the related change in fair value of the hedged item, alignment of the recognition and presentation of the effects of the hedging instrument and the hedged item, and permits an entity to exclude certain amounts related to currency swaps. Lastly, the ASU also provides additional relief on effectiveness testing methods and disclosures. The provisions of ASU No. 2017-12 are effective for us as of January 1, 2019, and early adoption is permitted. We have adopted this ASU as of January 1, 2018, which required the modified retrospective transition method upon adoption. The adoption of this ASU did not have a material impact to our consolidated financial statements. In February 2018, the FASB issued ASU No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income." ASU No. 2018-02 allows for the reclassification of the stranded tax effects resulting from the Tax Cuts and Jobs Act to retained earnings. The provisions of ASU No. 2018-02 are effective for us as of January 1, 2019, may be applied either at the beginning of the period of adoption or retrospectively, and early adoption is permitted. We adopted this ASU along with the adoption of ASU No. 2016-01 on January 1, 2018. Not Yet Adopted In February 2016, the FASB issued ASU No. 2016-02, "Leases." The ASU sets out the principles for the recognition, measurement, presentation and disclosure of leases for both lessees and lessors. The ASU requires lessees to adopt a right-of-use asset approach that will bring substantially all leases onto the balance sheet, with the exception of short-term leases. The subsequent accounting for this right-of-use asset will be based on a dual-model approach, under which the lease will be classified as either a finance or an operating lease. The lessor accounting model under this ASU is similar to current guidance, but certain underlying principles in the lessor model have been aligned with the new revenue recognition standard. This ASU was further updated by ASU 2018-01, "Land Easement Practical Expedient for Transition for Topic 842." The provisions of these ASUs are effective for us as of January 1, 2019, are required to be applied on a modified retrospective approach and early adoption is permitted. In January 2018, the FASB issued an exposure draft ("2018 Exposure Draft") which, if adopted as written, would allow lessors a practical expedient by class of underlying assets to account for lease and non-lease components as a single lease component if certain criteria are met. Also, the 2018 Exposure Draft indicates that companies may be permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of the modified retrospective approach and provides other optional practical expedients. We are in the process of evaluating the impact to our 5,200 lessor leases and other lessee leases, if any, that the adoption of this ASU will have on our consolidated financial statements. Within our lessor leases, we are entitled to receive tenant reimbursements for operating expenses such as real estate taxes, insurance and common area maintenance (“CAM”). Currently upon adoption of this ASU, CAM reimbursement revenue will be accounted for in accordance with Topic 606 (ASU No. 2014-09 as discussed above). We have currently identified some areas we believe may be impacted by this ASU. These include: • The bifurcation of lease arrangements in which contractual amounts due are on a gross basis and the amount under contract is not allocated between rental and expense reimbursements, such as real estate taxes and insurance. This process would be based on the underlying fair values of these items. • We have ground lease agreements in which we are the lessee for land underneath all or a portion of 13 centers and three administrative office leases that we account for as operating leases. Rental expense associated with these operating leases for the three months ended March 31, 2018 and 2017 was $.7 million and $.8 million , respectively. We have one capital lease in which we are the lessee of two centers with a $21 million lease obligation. We will record any rights and obligations under these leases as an asset and liability at fair value in our consolidated balance sheets. • Determination of costs to be capitalized associated with leases. This ASU will limit the capitalization associated with certain costs, primarily certain internally-generated leasing and legal costs, of which we capitalized internal costs of $2.5 million for the three months ended March 31, 2018 , and $10.8 million for the year ended December 31, 2017 . We believe we will be able to continue to capitalize internal leasing commissions that are a direct result of obtaining a lease. In June 2016, the FASB issued ASU No. 2016-13, "Measurement of Credit Losses on Financial Instruments." This ASU amends prior guidance on the impairment of financial instruments, and adds an impairment model that is based on expected losses rather than incurred losses with the recognition of an allowance based on an estimate of expected credit losses.
