Interim Financial Statements

Interim Financial Statements	6 Months Ended

Notes to Financial Statements [Abstract]
Interim Financial Statements	Interim Financial Statements General Taubman Centers, Inc. (the Company or TCO) is a Michigan corporation that operates as a self-administered and self-managed real estate investment trust (REIT). The Taubman Realty Group Limited Partnership (the Operating Partnership or TRG) is a majority-owned partnership subsidiary of TCO that owns direct or indirect interests in all of the Company’s real estate properties. In this report, the term “Company" refers to TCO, the Operating Partnership, and/or the Operating Partnership's subsidiaries as the context may require. The Company engages in the ownership, management, leasing, acquisition, disposition, development, and expansion of retail shopping centers and interests therein. The Company’s owned portfolio as of June 30, 2018 included 23 urban and suburban shopping centers operating in 11 U.S. states, Puerto Rico, South Korea, and China. Taubman Properties Asia LLC and its subsidiaries (Taubman Asia), which is the platform for the Company’s operations in China and South Korea, as well as any developments in Asia, is headquartered in Hong Kong. In May 2018, the Company closed on a redevelopment agreement for Taubman Prestige Outlets Chesterfield. As of May 1, 2018, all operations at the center, as well as the building and improvements, have been transferred to The Staenberg Group (“TSG”), and TSG leases the land from the Company through a long-term, participating ground lease. Both the Company and TSG have the ability to terminate the ground lease in the event that a redevelopment has not begun within five years , with the buildings and improvements reverting to the Company upon such a termination. The Company will defer recognition of a sale of the building and improvements and maintains the property on its Consolidated Balance Sheet until the foregoing termination right is no longer available to the parties, with this right ceasing upon TSG commencing a redevelopment. The shopping center has been excluded from the Company's owned shopping center portfolio disclosure above. The unaudited interim financial statements should be read in conjunction with the audited financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . In the opinion of management, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the financial statements for the interim periods have been made. The results of interim periods are not necessarily indicative of the results for a full year. Dollar amounts presented in tables within the notes to the financial statements are stated in thousands, except share data or as otherwise noted. Consolidation The consolidated financial statements of the Company include all accounts of the Company, the Operating Partnership, and its consolidated subsidiaries, including The Taubman Company LLC (the Manager) and Taubman Asia. All intercompany transactions have been eliminated. The entities included in these consolidated financial statements are separate legal entities and maintain records and books of account separate from any other entity. However, inclusion of these separate entities in the consolidated financial statements does not mean that the assets and credit of each of these legal entities are available to satisfy the debts or other obligations of any other such legal entity included in the consolidated financial statements. In determining the method of accounting for partially owned joint ventures, the Company evaluates the characteristics of associated entities and determines whether an entity is a variable interest entity (VIE), and, if so, determines whether the Company is the primary beneficiary by analyzing whether the Company has both the power to direct the entity's significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the nature of the entity's operations, the entity's financing and capital structure, and contractual relationship and terms, including consideration of governance and decision making rights. The Company consolidates a VIE when it has determined that it is the primary beneficiary. All of the Company’s consolidated joint ventures, including the Operating Partnership, meet the definition and criteria as VIEs, as either the Company or an affiliate of the Company is the primary beneficiary of each VIE. The Company’s sole significant asset is its investment in the Operating Partnership and, consequently, substantially all of the Company’s consolidated assets and liabilities are assets and liabilities of the Operating Partnership. All of the Company’s debt (Note 5) is an obligation of the Operating Partnership or its consolidated subsidiaries. Note 5 also provides disclosure of guarantees provided by the Operating Partnership to certain consolidated joint ventures. Note 6 provides additional disclosures of the carrying balance of the noncontrolling interests in its consolidated joint ventures and other information, including a description of certain rights of the noncontrolling owners. Investments in entities not controlled but over which the Company may exercise significant influence (Unconsolidated Joint Ventures or UJVs) are accounted for under the equity method. The Company has evaluated its investments in the Unconsolidated Joint Ventures under guidance for determining whether an entity is a VIE and has concluded that the ventures are not VIEs. Accordingly, the Company accounts for its interests in these entities under general accounting standards for investments in real estate ventures (including guidance for determining effective control of a limited partnership or similar entity). The Company’s partners or other owners in these Unconsolidated Joint Ventures have substantive participating rights including approval rights over annual operating budgets, capital spending, financing, admission of new partners/members, or sale of the properties and the Company has concluded that the equity method of accounting is appropriate for these interests. Specifically, the Company’s 79% and 50.1% investments in Westfarms and International Plaza, respectively, are through general partnerships in which the other general partners have participating rights over annual operating budgets, capital spending, refinancing, or sale of the property. The Company provides its beneficial interest in certain financial information of its Unconsolidated Joint Ventures (Notes 4 and 5). This beneficial information is derived as the Company's ownership interest in the investee multiplied by the specific financial statement item being presented. Investors are cautioned that deriving the Company's beneficial interest in this manner may not accurately depict the legal and economic implications of holding a noncontrolling interest in the investee. Ownership In addition to common stock, there were three classes of preferred stock outstanding (Series B, J, and K) as of June 30, 2018 . Dividends on the 6.5% Series J Cumulative Redeemable Preferred Stock (Series J Preferred Stock) and the 6.25% Series K Cumulative Redeemable Preferred Stock (Series K Preferred Stock) are cumulative and are paid on the last business day of each calendar quarter. The Company owns corresponding Series J and Series K Preferred Equity interests in the Operating Partnership that entitle the Company to income and distributions (in the form of guaranteed payments) in amounts equal to the dividends payable on the Company’s Series J and Series K Preferred Stock. The Company also is obligated to issue to partners in the Operating Partnership other than the Company, upon subscription, one share of nonparticipating Series B Preferred Stock per each unit of limited partnership in TRG (TRG Unit) . The Series B Preferred Stock entitles its holders to one vote per share on all matters submitted to the Company’s shareowners and votes together with the common stock on such matters as a single class. The holders of Series B Preferred Stock are not entitled to dividends or earnings. The Series B Preferred Stock is convertible into common stock at a ratio of 14,000 shares of Series B Preferred Stock for one share of common stock . Outstanding voting securities of the Company at June 30, 2018 consisted of 24,937,221 shares of Series B Preferred Stock and 60,992,212 shares of common stock. The Operating Partnership At June 30, 2018 , the Operating Partnership’s equity included two classes of preferred equity (Series J and K) and the net equity of the TRG unitholders. Net income and distributions of the Operating Partnership are allocable first to the preferred equity interests, and the remaining amounts to the general and limited partners in the Operating Partnership in accordance with their percentage ownership. The Series J and Series K Preferred Equity are owned by the Company and are eliminated in consolidation. The Company's ownership in the Operating Partnership at June 30, 2018 consisted of a 71% managing general partnership interest, as well as the Series J and Series K Preferred Equity interests. The Company's average ownership percentage in the Operating Partnership for both the six months ended June 30, 2018 and 2017 was 71% . At June 30, 2018 , the Operating Partnership had 85,944,193 TRG Units outstanding, of which the Company owned 60,992,212 TRG Units. Disclosures about TRG Units outstanding exclude TRG Profits Units granted or other share-based grants for which TRG Units may eventually be issued (Note 8). Restructuring Charge The Company has been undergoing a restructuring to reduce its workforce and reorganize various areas of the organization in response to the completion of another major development cycle and the current near-term challenges facing the U.S. mall industry. During the three and six months ended June 30, 2018 , the Company recorded a change in estimate to previously recognized charges resulting in a reversal of expense of $0.1 million and $0.4 million , respectively. During the three and six months ended June 30, 2017 , the Company incurred $0.4 million and $2.3 million , respectively, of expenses related to the restructuring. These expenses and adjustments thereto have been separately classified as Restructuring Charge on the Consolidated Statement of Operations and Comprehensive Income. As of June 30, 2018 , $0.4 million of the restructuring costs recognized during 2017 and 2018 were unpaid and remained accrued. Costs Associated with Shareowner Activism During both the three and six months ended June 30, 2018 and 2017 , the Company incurred $5.0 million and $8.5 million , respectively, of expense associated with activities related to shareowner activism, largely legal and advisory services. Also included in the activism costs for the three and six months ended June 30, 2018 is a retention program for certain employees. Given the uncertainties associated with shareowner activism and to ensure the retention of top talent in key positions within the Company, certain key employees were provided certain incentive benefits in the form of cash and/or equity retention awards. The Company and the Board of Directors believe these benefits are instrumental in ensuring the continued success of the Company during the retention period. Due to the unusual and infrequent nature of these expenses in the Company's history, they have been separately classified as Costs Associated with Shareowner Activism on the Company's Consolidated Statement of Operations and Comprehensive Income. Unvested incentive benefits under the retention awards as of June 30, 2018 were $2.7 million , which will be recognized as service is rendered through December 31, 2019. Management’s Responsibility to Evaluate the Company’s Ability to Continue as a Going Concern When preparing financial statements for each annual and interim reporting period, management has the responsibility to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued. No such conditions or events were identified as of the issuance date of the financial statements contained in this Quarterly Report on Form 10-Q. Change in Accounting Policies Recognition and Measurement of Financial Assets and Financial Liabilities On January 1, 2018, the Company adopted Accounting Standards Update (ASU) No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities", which changed certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. As such, the Company now measures equity investments at fair value through net income, except for those that result in consolidation or are accounted for under the equity method. Upon adoption, the Company applied the modified-retrospective approach and recorded a one-time cumulative-effect adjustment to reclassify $1.0 million of historical unrealized gains on the fair value adjustments as of December 31, 2017 of its 590,124 Simon Property Group (SPG) common shares investment from Accumulated Other Comprehensive Income (Loss) (AOCI) to Dividends in Excess of Net Income on the Company's Consolidated Balance Sheet. Beginning in January 2018, changes in the fair value of any outstanding SPG common shares are being recorded in Nonoperating Income, Net on the Company's Consolidated Statement of Operations and Comprehensive Income (Note 11). Cash Flow Statement Presentation On January 1, 2018, the Company adopted ASU No. 2016-18, "Statement of Cash Flows - Restricted Cash", which changed the presentation of restricted cash and changes in restricted cash on the Consolidated Statement of Cash Flows. As a result, the Company changed the presentation of its Consolidated Statement of Cash Flows for both the six months ended June 30, 2018 and 2017 to include restricted cash. Refer to Note 13 for a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheet that sum to the total of the same such amounts on the Consolidated Statement of Cash Flows. In connection with the adoption this ASU, the Company revisited its accounting policies and presentation in regards to cash, deposits, and other investments subject to restrictions. In doing so, the Company reclassified $119.2 million from Deferred Charges and Other Assets to Restricted Cash on the Consolidated Balance Sheet as of December 31, 2017, to conform to current year classifications. On January 1, 2018, the Company adopted ASU No. 2016-15, "Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments", which clarified the presentation of certain cash receipts and payments, including the classification of distributions received from equity method investees, on the Consolidated Statement of Cash Flows. In connection with the adoption of this ASU on January 1, 2018, the Company re-evaluated its current methodology and retrospectively changed the presentation of the Consolidated Statement of Cash Flows for the six months ended June 30, 2017 to re-classify prior year balances to correspond with current year classifications, specifically related to distributions received from equity method investees. Adoption of Accounting Standards Codification (ASC) Topic 606 ("Revenue from Contracts with Customers") General On January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers. ASC Topic 606 provides a single comprehensive model to use in accounting for revenue arising from contracts with customers, and gains and losses arising from transfers of non-financial assets including sales of property and equipment, real estate, and intangible assets. The Company adopted ASC Topic 606 for all applicable contracts using the modified retrospective method, which would have required a cumulative-effect adjustment, if any, as of the date of adoption. The adoption of ASC Topic 606 did not have a material impact on the Company's consolidated financial statements as of the date of adoption, and therefore a cumulative-effect adjustment was not required. The Company applied ASC Topic 606 using certain practical expedients. As a result of this election, the Company will not disclose the aggregate amount of the transaction price for unsatisfied, or partially unsatisfied, performance obligations for all contracts with an original expected length of one year or less and management contracts for which the Company recognizes revenue based on its right to invoice for management, leasing, and development services performed. Refer to the "Nature of Services and Performance Obligations" section for further discussion of these services. Disaggregation of Revenue The nature, amount, timing, and uncertainty of individual types of revenues may be affected differently by economic factors. Under ASC Topic 606, the Company is required to disclose a disaggregation of its revenues derived from contracts from customers that considers economic differences between revenue types. The following table summarizes the Company’s disaggregation of consolidated revenues for this purpose. Three Months Ended June 30 Six Months Ended June 30 2018 2017 2018 2017 Expense recoveries $ 50,553 $ 49,413 $ 102,081 $ 102,425 Shopping center and other operational revenues (1) 10,817 10,860 21,637 18,504 Management, leasing, and development services 826 1,375 1,620 2,292 Total revenue from contracts with customers $ 62,196 $ 61,648 $ 125,338 $ 123,221 (1) Represents consolidated Other revenue reported on the Consolidated Statement of Operations and Comprehensive Income excluding lease cancellation income. Nature of Services and Performance Obligations Expense recoveries revenue represents reimbursements from mall tenants for (1) services performed by the Company to the benefit of all mall tenants and the property as a whole for common area maintenance, (2) insurance, property taxes, and utilities, and (3) promotion and other miscellaneous charges. As these expense recoveries are provided for under tenant lease agreements, these revenues will not be evaluated under ASC Topic 606 until the Company's adoption of ASU No. 2016-02, Leases, which will be adopted as of January 1, 2019. Shopping center and other operational revenues represent a collection of non-core revenue streams that are generated through the course of owning and operating a shopping center, including sponsorship, parking, and storage income, as well as revenues from food and beverage operations. The contracts for these revenue streams are predominately short-term in nature and individually do not contain more than one performance obligation. The Company satisfies its performance obligations related to shopping center and other operational revenues either over time or at a point in time, depending on the specific nature of the revenue generating activity. For performance obligations that are satisfied at a point in time, including food and beverage and parking income, the control of the good or service is immediately transferred to the customer upon completion of the performance obligation. Payment terms related to shopping center and other operational revenues vary depending on the nature of the agreement, however, payment is generally due directly upon the satisfaction of the related performance obligation. Management, leasing, and development services revenue represents income from various services performed by the Company for its third party customers, as provided for under management agreements. These services typically generate fees that are based on operating results of the shopping centers, the execution and opening of mall tenants, and/or the successful completion of other agreed-upon services. As each management agreement provides for a variety of services, significant judgment is required to identify multiple performance obligations. The standalone selling price of each performance obligation is determined based on the terms of the management agreement and the specific services being rendered. Each performance obligation is considered to be satisfied over time as services are rendered. The related revenue is recognized upon billing, as the amounts invoiced generally correspond directly with the value the customer is receiving from the services. Customers are invoiced on quarterly basis and payment is generally due within 30 days of each calendar quarter. Information about Contract Balances and Unsatisfied Performance Obligations Contract assets exist when the Company has a right to payment for services rendered that remains conditional on factors other than the passage of time. Similarly, contract liabilities are incurred when customers prepay for services to be rendered. Certain revenue streams within shopping center and other operational revenues may give rise to contract assets and liabilities. However, these revenue streams are generally short-term in nature and the difference between revenue recognition and cash collection, although variable, does not differ significantly from period to period. As of June 30, 2018 , the Company had an inconsequential amount of contract assets and liabilities. The aggregate amount of the transaction price allocated to the Company's performance obligations that were unsatisfied, or partially unsatisfied, as of June 30, 2018 were inconsequential.

Disposition, Redevelopments, and Developments [Text Block]	Disposition, Redevelopments, and Developments Disposition Valencia Place Office Tower at Country Club Plaza In March 2017, the Company's joint venture with The Macerich Company sold the Valencia Place office tower at Country Club Plaza for $75.2 million ( $37.6 million at TRG's beneficial share), which was a component of the mixed-use property at the center. The joint venture recognized a gain on this sale, of which TRG's beneficial share, net of tax, was $2.1 million . The gain was included within Equity in income of Unconsolidated Joint Ventures on the Consolidated Statement of Operations and Comprehensive Income as the Company's 50% ownership interest in the office tower was accounted for as an Unconsolidated Joint Venture under the equity method. Redevelopments The Company has ongoing redevelopment projects at Beverly Center and The Mall at Green Hills, which are expected to be completed in 2018 and 2019, respectively. In total, these two redevelopment projects are expected to cost approximately $700 million . As of June 30, 2018 , the Company's total capitalized costs related to these redevelopment projects were $469.1 million . Asia Developments Operating Center CityOn.Zhengzhou, a shopping center located in Zhengzhou, China, opened in March 2017. This investment is classified within Investment in Unconsolidated Joint Ventures on the Consolidated Balance Sheet. South Korea Projects The Company has partnered with Shinsegae Group, the Company's partner in Starfield Hanam, to build, lease, and manage Starfield Anseong, an approximately 1.1 million square foot shopping center in Anseong, Gyeonggi Province, South Korea. The Company expects to beneficially own a 24.5% interest in the project; however the Company currently owns and is funding 49% of the project until an additional capital partner is admitted. The center is scheduled to open in late 2020. As of June 30, 2018 , the Company has invested $88.6 million in the project, after cumulative currency translation adjustments. This investment is classified within Investment in Unconsolidated Joint Ventures on the Consolidated Balance Sheet. The Company was previously exploring an additional development opportunity in South Korea with Shinsegae Group. In March 2017, the Company made a refundable deposit of $11.0 million relating to a potential development site. After performing due diligence, the Company decided not to proceed with the project. The deposit, including a 5% return, was returned to the Company in November 2017.

A corresponding reduction in properties assets was recorded to reflect the deferral method of accounting for tax credits. During the fourth quarter of 2017, the Tax Cuts and Jobs Act of 2017 was signed into law and reduced the corporate tax rate from 34% down to 21% . All Federal deferred tax assets and liabilities have been reported at the new 21% Federal corporate rate. The Company believes that it is more likely than not that the results of future operations will generate sufficient taxable income to recognize the net deferred tax assets. These future operations are primarily dependent upon the Manager’s profitability, the timing and amounts of gains on peripheral land sales, the profitability of Taubman Asia's operations, and other factors affecting the results of operations of the taxable REIT subsidiaries. The valuation allowances relate to net operating loss carryforwards and tax basis differences where there is uncertainty regarding their realizability.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Joint Ventures	Investments in Unconsolidated Joint Ventures General Information The Company owns beneficial interests in joint ventures that own shopping centers. The Operating Partnership is the sole direct or indirect managing general partner or managing member of Fair Oaks Mall, International Plaza, Stamford Town Center, Sunvalley, The Mall at University Town Center, and Westfarms; however, these joint ventures are accounted for under the equity method due to the substantive participation rights of the outside partners. The Operating Partnership also provides certain management, leasing, and/or development services to the other shopping centers noted below. Shopping Center Ownership as of June 30, 2018 and December 31, 2017 CityOn.Xi'an 50% CityOn.Zhengzhou 49 Country Club Plaza 50 Fair Oaks Mall 50 International Plaza 50.1 The Mall at Millenia 50 Stamford Town Center 50 Starfield Anseong (under development) Note 2 Starfield Hanam 34.3 Sunvalley 50 The Mall at University Town Center 50 Waterside Shops 50 Westfarms 79 The Company's carrying value of its investment in Unconsolidated Joint Ventures differs from its share of the partnership or members’ equity reported on the combined balance sheet of the Unconsolidated Joint Ventures due to (i) the Company's cost of its investment in excess of the historical net book values of the Unconsolidated Joint Ventures and (ii) the Operating Partnership’s adjustments to the book basis, including intercompany profits on sales of services that are capitalized by the Unconsolidated Joint Ventures. The Company's additional basis allocated to depreciable assets is recognized on a straight-line basis over 40 years . The Operating Partnership’s differences in bases are amortized over the useful lives or terms of the related assets and liabilities. In its Consolidated Balance Sheet, the Company separately reports its investment in Unconsolidated Joint Ventures for which accumulated distributions have exceeded investments in and net income of the Unconsolidated Joint Ventures. The net equity of certain joint ventures is less than zero because distributions are usually greater than net income, as net income includes non-cash charges for depreciation and amortization. In addition, any distributions related to refinancing of the centers further decrease the net equity of the centers. Combined Financial Information Combined balance sheet and results of operations information is presented in the following table for the Unconsolidated Joint Ventures, followed by the Operating Partnership's beneficial interest in the combined operations information. The combined financial information of the Unconsolidated Joint Ventures as of June 30, 2018 excludes the balances of Starfield Anseong, which was under development as of June 30, 2018 (Note 2).

The capitalized interest cost is included in the Company's basis in its investment in Unconsolidated Joint Ventures. Such capitalized interest reduces interest expense on the Consolidated Statement of Operations and Comprehensive Income and in the table above is included within Consolidated Subsidiaries. (2) Capitalized interest on the Asia Unconsolidated Joint Venture construction financing is presented at the Company's beneficial interest in both the Unconsolidated Joint Ventures (at 100%) and Unconsolidated Joint Ventures (at Beneficial Interest) columns. 2018 Financings In March 2018, the Company completed a five -year, $ 250 million unsecured term loan. TRG is the borrower under the loan, which bears interest at a range of LIBOR plus 1.25% to LIBOR plus 1.90% based on the Company's total leverage ratio. The proceeds from this financing, in conjunction with the proceeds from the financing for Twelve Oaks Mall (see below), were used to pay off the Company's existing $ 475 million unsecured term loan. The Company's existing swaps on the $ 475 million unsecured term loan were applied to other unsecured debt, including the new $ 250 million unsecured term loan, resulting in an effective interest rate on the new term loan in the range of 2.89% to 3.54% through the remaining swap period ending in February 2019 . The loan includes an accordion feature which would increase the Company's borrowing capacity to as much as $400 million if fully exercised, subject to obtaining additional lender commitments, customary closing conditions, covenant compliance, and minimum asset values for the unencumbered asset pool. In February 2018, a 10 -year, $ 300 million non-recourse financing was completed for Twelve Oaks Mall. The payments on the loan, which bears interest at a fixed interest rate of 4.85% , began in April 2018 and are amortizing principal based on 30 years . As a result of this financing, Twelve Oaks Mall was removed as a guarantor and an unencumbered asset under the primary unsecured revolving line of credit and the unsecured term loans. Upcoming Maturities The construction facility for International Market Place was scheduled to mature in August 2018. As of June 30, 2018 , the outstanding balance of this construction facility was $293.8 million . In July 2018, the Company extended the construction facility for 90 days to November 2018, and in connection with the extension, the Company made a repayment on the facility of $43.8 million , to reduce the outstanding balance to $250.0 million . No further draws are allowed on the construction facility. The Company expects to refinance this construction facility with a three -year, $250 million financing at an interest rate of LIBOR plus 2.15% in August 2018. The loan is expected to be fully guaranteed by the Operating Partnership. The loan for The Mall at Green Hills matures in December 2018. The Company plans to exercise the initial one-year extension option upon maturity. Debt Covenants and Guarantees Certain loan agreements contain various restrictive covenants, including the following corporate covenants on the Company’s primary unsecured revolving line of credit, $300 million and $250 million unsecured term loans, and the construction facility on International Market Place: a minimum net worth requirement, a maximum total leverage ratio, a maximum secured leverage ratio, a minimum fixed charge coverage ratio, a maximum recourse secured debt ratio, and a maximum payout ratio. In addition, the Company’s primary unsecured revolving line of credit and unsecured term loans have unencumbered pool covenants, which currently apply to Beverly Center, Dolphin Mall, and The Gardens on El Paseo on a combined basis. These covenants include a minimum number and minimum value of eligible unencumbered assets, a maximum unencumbered leverage ratio, a minimum unencumbered interest coverage ratio, and a minimum unencumbered asset occupancy ratio. As of June 30, 2018 , the corporate total leverage ratio was the most restrictive covenant. The Company was in compliance with all of its covenants and loan obligations as of June 30, 2018 . The maximum payout ratio covenant limits the payment of distributions generally to 95% of funds from operations, as defined in the loan agreements, except as required to maintain the Company’s tax status, pay preferred distributions, and for distributions related to the sale of certain assets. In connection with the financing of the construction facility at International Market Place, the Operating Partnership has provided an unconditional guarantee of the construction loan principal balance and all accrued but unpaid interest during the term of the loan. The Operating Partnership has also provided a guarantee as to the completion of construction of the center. The outstanding balance of the International Market Place construction facility as of June 30, 2018 was $293.8 million . Accrued but unpaid interest as of June 30, 2018 was $0.9 million . The Company believes the likelihood of a payment under the guarantees to be remote. Refer to "Upcoming Maturities" above regarding a recent partial repayment on this facility, as well as the Company's expectation to refinance it. In connection with the $175 million additional financing at International Plaza, which is owned by an Unconsolidated Joint Venture, the Operating Partnership provided an unconditional and several guarantee of 50.1% of all obligations and liabilities related to an interest rate swap that was required on the debt for the term of the loan. As of June 30, 2018 , the interest rate swap was an asset and in a receivable position for unpaid interest. The Company believes the likelihood of a payment under the guarantee to be remote.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Redeemable Noncontrolling Interests Taubman Asia President In September 2016, the Company announced the appointment of Peter Sharp (Successor Asia President) as president of Taubman Asia, a consolidated subsidiary, succeeding René Tremblay (Former Asia President) effective January 1, 2017. The Former Asia President was employed by the Company in another capacity through September 30, 2017. The Former Asia President has an ownership interest in Taubman Asia. This interest entitles the Former Asia President to 5% of Taubman Asia's dividends, with 85% of his dividends relating to investment activities undergone prior to the Successor Asia President obtaining an ownership interest (see below) being withheld as contributions to capital. These withholdings will continue until he contributes and maintains his capital consistent with his percentage ownership interest, including all capital funded by the Operating Partnership for Taubman Asia's operating and investment activities subsequent to the Former Asia President obtaining his ownership interest. The Operating Partnership has a preferred investment in Taubman Asia to the extent the Former Asia President has not yet contributed capital commensurate with his ownership interest. This preferred investment accrues an annual preferential return equal to the Operating Partnership's average borrowing rate (with the preferred investment and accrued return together being referred to herein as the preferred interest). In addition, Taubman Asia has the ability to call, and the Former Asia President has the ability to put, the Former Asia President’s ownership interest upon Taubman Asia's properties reaching certain specified milestones. The redemption price for the ownership interest is the fair value of the ownership interest less the amount required to return the Operating Partnership's preferred interest. The Company has determined that the Former Asia President's ownership interest in Taubman Asia qualifies as an equity award, considering its specific redemption provisions, and accounts for it as a contingently redeemable noncontrolling interest. The Company presents as temporary equity at each balance sheet date an estimate of the redemption value of the ownership interest, therefore falling into level 3 of the fair value hierarchy. As of both June 30, 2018 and December 31, 2017 , the carrying amount of this redeemable equity was $7.5 million . Any adjustments to the redemption value are recorded through equity. In April 2016, the Company reacquired half of the Former Asia President’s previous 10% ownership interest in Taubman Asia for $7.2 million . The Former Asia President contributed $2 million to Taubman Asia, which may be returned, in part or in whole, upon satisfaction of the re-evaluation of the full liquidation value of Taubman Asia as of April 2016; such re-evaluation will be performed at the Former Asia President's election on or after the third anniversary of the opening of specified Asia projects. The Former Asia President’s current 5% interest is puttable beginning in 2019 at the earliest and was classified as Redeemable Noncontrolling Interest on the Consolidated Balance Sheet. The Successor Asia President also has an ownership interest in Taubman Asia. This interest entitles the Successor Asia President to 3% of Taubman Asia's dividends for investment activities undergone by Taubman Asia subsequent to him obtaining his ownership interest, with all of his dividends being withheld as contributions to capital. These withholdings will continue until he contributes and maintains his capital consistent with his percentage ownership interest, including all capital funded by the Operating Partnership for Taubman Asia's operating and investment activities subsequent to the Successor Asia President obtaining his ownership interest. The Operating Partnership has a preferred investment in Taubman Asia to the extent the Successor Asia President has not yet contributed capital commensurate with his ownership interest. This preferred investment accrues an annual preferential return equal to the Operating Partnership's average borrowing rate (with the preferred investment and accrued return together being referred to herein as the preferred interest). In addition, Taubman Asia has the ability to call, and the Successor Asia President has the ability to put, the Successor Asia President’s ownership interest upon specified terminations of the Successor Asia President’s employment, although such put or call right may not be exercised for specified time periods after certain termination events. The redemption price for the ownership interest is 50% (increasing to 100% as early as January 2022) of the fair value of the ownership interest less the amount required to return the Operating Partnership's preferred interest. The Company has determined that the Successor Asia President's ownership interest in Taubman Asia qualifies as an equity award, considering its specific redemption provisions, and accounts for it as a contingently redeemable noncontrolling interest. As of June 30, 2018 , the carrying amount of this redeemable equity was zero . Any adjustments to the redemption value are recorded through equity. International Market Place The Company owns a 93.5% controlling interest in a joint venture that owns International Market Place in Waikiki, Honolulu, Hawaii, which opened in August 2016. The 6.5% joint venture partner has no obligation and no right to contribute capital. The Company is entitled to a preferential return on its capital contributions. The Company has the right to purchase the joint venture partner's interest and the joint venture partner has the right to require the Company to purchase the joint venture partner's interest after the third anniversary of the opening of the center, and annually thereafter. The purchase price of the joint venture partner's interest will be based on fair value. Considering the redemption provisions, the Company accounts for the joint venture partner's interest as a contingently redeemable noncontrolling interest with a carrying value of zero at both June 30, 2018 and December 31, 2017 . Any adjustments to the redemption value are recorded through equity.

Finite Life Entities ASC Topic 480, “Distinguishing Liabilities from Equity” establishes standards for classifying and measuring as liabilities certain financial instruments that embody obligations of the issuer and have characteristics of both liabilities and equity. At June 30, 2018 , the Company held a controlling interest in a consolidated entity with a specified termination date in 2083 . The noncontrolling owners' interest in this entity is to be settled upon termination by distribution or transfer of either cash or specific assets of the underlying entity. The estimated fair value of this noncontrolling interest was approximately $360 million at June 30, 2018 , compared to a book value of $(158.8) million that is classified in Noncontrolling Interests on the Company’s Consolidated Balance Sheet. The fair value of the noncontrolling interest was calculated as the noncontrolling interest's effective ownership share of the underlying property's fair value. The property's fair value was estimated by considering its in-place net operating income, current market capitalization rate, and mortgage debt outstanding.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities Risk Management Objective and Strategies for Using Derivatives The Company uses derivative instruments, such as interest rate swaps and interest rate caps, primarily to manage exposure to interest rate risks inherent in variable rate debt and refinancings. 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. The Company’s 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. Interest rate caps involve the receipt of variable-rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. 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. The Company does not use derivatives for trading or speculative purposes and currently does not have any derivatives that are not designated as hedging instruments under the accounting requirements for derivatives and hedging. As of June 30, 2018 , the Company had the following outstanding derivatives that were designated and are expected to be effective as cash flow hedges of the interest payments and/or the currency exchange rate on the associated debt. Instrument Type Ownership Notional Amount Swap Rate Credit Spread on Loan Total Swapped Rate on Loan Maturity Date Consolidated Subsidiaries: Receive variable (LIBOR) /pay-fixed swap (1) 100 % $ 200,000 1.64 % 1.90 % (1) 3.54 % (1) February 2019 Receive variable (LIBOR) /pay-fixed swap (1) 100 % 175,000 1.65 % 1.70 % (1) 3.35 % (1) February 2019 Receive variable (LIBOR) /pay-fixed swap (1) 100 % 100,000 1.64 % 1.90% / 1.70% (1) 3.54% / 3.34% (1) February 2019 Receive variable (LIBOR) /pay-fixed swap (2) 100 % 100,000 2.14 % 1.90 % (2) 4.04 % (2) February 2022 Receive variable (LIBOR) /pay-fixed swap (2) 100 % 100,000 2.14 % 1.90 % (2) 4.04 % (2) February 2022 Receive variable (LIBOR) /pay-fixed swap (2) 100 % 50,000 2.14 % 1.90 % (2) 4.04 % (2) February 2022 Receive variable (LIBOR) /pay-fixed swap (2) 100 % 50,000 2.14 % 1.90 % (2) 4.04 % (2) February 2022 Receive variable (LIBOR) /pay-fixed swap (3) 100 % 12,000 2.09 % 1.40 % 3.49 % March 2024 Unconsolidated Joint Ventures: Receive variable (LIBOR) /pay-fixed swap (4) 50.1 % 163,942 1.83 % 1.75 % 3.58 % December 2021 Receive variable (LIBOR) USD/pay-fixed Korean Won (KRW) cross-currency interest rate swap (5) 34.3 % 52,065 USD / 60,500,000 KRW 1.52 % 1.60 % 3.12 % September 2020 (1) The hedged forecasted transaction for each of these swaps is the first previously unhedged one-month LIBOR -indexed interest payments accrued and made each month on a debt principal amount equal to the swap notional amount, regardless of the specific debt agreement from which they may flow. The Company is currently using these swaps to manage interest rate risk on the $ 250 million unsecured term loan and $ 225 million on the $ 1.1 billion primary unsecured revolving line of credit. The credit spreads on these loans can vary within a range of 1.25% to 1.90% on the $ 250 million unsecured term loan and 1.15% to 1.70% on the primary unsecured revolving line of credit, depending on the Company's total leverage ratio at the measurement date, resulting in an effective rate in the range of 2.89% to 3.54% on the $ 250 million unsecured term loan and 2.80% to 3.35% on $ 225 million of the $ 1.1 billion primary unsecured revolving line of credit during the remaining swap period. (2) The hedged forecasted transaction for each of these swaps is the first previously unhedged one-month LIBOR -indexed interest payments accrued and made each month on a debt principal amount equal to the swap notional amount, regardless of the specific debt agreement from which they may flow. The Company is currently using these swaps to manage interest rate risk on its $300 million unsecured term loan. The credit spread on this loan can vary within a range of 1.25% to 1.90% , depending on the Company's total leverage ratio at the measurement date, resulting in an effective rate in the range of 3.39% to 4.04% during the swap period. (3) The notional amount on this swap is equal to the outstanding principal balance of the floating rate loan on the U.S. headquarters building. (4) The notional amount on this swap is equal to the outstanding principal balance of the floating rate loan on International Plaza. (5) The notional amount on this swap is equal to the outstanding principal balance of the U.S. dollar construction loan for Starfield Hanam. There is a cross-currency interest rate swap to fix the interest rate on the loan and swap the related principal and interest payments from U.S. dollars to KRW in order to reduce the impact of fluctuations in interest rates and exchange rates on the cash flows of the joint venture. The currency swap exchange rate is 1,162.0 . Cash Flow Hedges On January 1, 2018, the Company early adopted ASU No. 2017-12, "Targeted Improvements to Accounting for Hedging Activities", which provided changes in hedge accounting recognition and presentation requirements. The Company now recognizes all changes in fair value for hedging instruments designated and qualifying for cash flow hedge accounting treatment as a component of Other Comprehensive Income (OCI), as opposed to previously recognizing the ineffective portion, if any, directly in earnings. Upon adoption, the Company applied the modified-retrospective approach and recorded a one-time cumulative-effect adjusting entry to reclassify an inconsequential amount of previous hedge ineffectiveness for cash flow hedges from Dividends in Excess of Net Income to AOCI on the Company's Consolidated Balance Sheet. For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the unrealized gain or loss on the derivative is reported as a component of OCI. Prior to the adoption of ASU No. 2017-12 on January 1, 2018, the ineffective portion of the change in fair value, if any, was recognized directly in earnings. Beginning January 1, 2018, all unrealized gains or losses on the derivatives are reported as components of OCI. 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 AOCI during the term of the hedged debt transaction. Amounts reported in AOCI related to currently outstanding interest rate derivatives are recognized as an adjustment to income 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. Amounts reported in AOCI related to the cross-currency interest rate swap are recognized as an adjustment to income as transaction gains or losses arising from the remeasurement of foreign currency denominated loans are recognized and as actual interest and principal obligations are repaid. The Company expects that approximately $3.5 million of the AOCI of Taubman Centers, Inc. and the noncontrolling interests will be reclassified from AOCI and recognized as an increase to income in the following 12 months. The following tables present the effect of derivative instruments on the Consolidated Statement of Operations and Comprehensive Income for the three and six months ended June 30, 2018 and 2017 . The tables include the amount of gains or losses on outstanding derivative instruments recognized in OCI in cash flow hedging relationships and the location and amount of gains or losses reclassified from AOCI into income resulting from outstanding derivative instruments.

Fair Value Consolidated Balance Sheet Location June 30, December 31, Derivatives designated as hedging instruments: Asset derivatives: Interest rate contracts – consolidated subsidiaries Deferred Charges and Other Assets $ 8,373 $ 939 Interest rate contract - UJV Investment in UJVs 2,268 760 Total assets designated as hedging instruments $ 10,641 $ 1,699 Liability derivatives: Interest rate contracts – consolidated subsidiary Accounts Payable and Accrued Liabilities $ (484 ) Interest rate contracts – UJV Investment in UJVs (357 ) Cross-currency interest rate contract – UJV Investment in UJVs $ (928 ) (1,630 ) Total liabilities designated as hedging instruments $ (928 ) $ (2,471 ) Contingent Features All of the Company's outstanding derivatives contain provisions that state if the hedged entity defaults on its indebtedness above a certain threshold, then the derivative obligation could also be declared in default. The cross default thresholds vary for each agreement, ranging from $0.1 million of any indebtedness to $50 million of indebtedness on the Operating Partnership's indebtedness. As of June 30, 2018 , the Company is not in default on any indebtedness that would trigger a credit-risk-related default on its current outstanding derivatives. As of June 30, 2018 and December 31, 2017 , the fair value of derivative instruments with credit-risk-related contingent features that were in a liability position was $0.9 million and $2.5 million , respectively. As of June 30, 2018 and December 31, 2017 , the Company was not required to post any collateral related to these agreements. If the Company breached any of these provisions it would be required to settle its obligations under the agreements at their fair value. See Note 5 regarding guarantees and Note 11 for fair value information on derivatives.

Share-Based Compensation

Share-Based Compensation	6 Months Ended

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share-Based Compensation	Share-Based Compensation General In May 2018, the Company’s shareowners approved The Taubman Company LLC 2018 Omnibus Long-Term Incentive Plan (2018 Omnibus Plan). The 2018 Omnibus Plan provides for the award to directors, officers, employees, and other service providers of the Company and its affiliates of restricted shares, restricted share units, restricted profits units of TRG (TRG Profits Units), options to purchase common shares, unrestricted shares, and dividend equivalent rights, in each case with or without performance conditions, to acquire up to an aggregate of 2.8 million common shares or TRG Profits Units. Every share or TRG Profits Unit subject to awards under the 2018 Omnibus Plan shall be counted against this limit as one share or TRG Profits Unit for every one share or TRG Profits Unit granted . The amount of shares or TRG Profits Units available for future grants is adjusted when the number of contingently issuable common shares or units are settled. If an award issued under the 2018 Omnibus Plan is forfeited, expires without being exercised, or is used to pay tax withholding on such award, the shares of TRG Profits Units become available for issuance under new award. TRG Profits Units are intended to constitute "profits interests" within the meaning of Treasury authority under the Internal Revenue Code of 1986, as amended. In addition, non-employee directors have the option to defer their compensation under a deferred compensation plan. The 2018 Omnibus Plan allows the Company to permit or require the deferral of all or a part of an award payment into a deferred compensation arrangement. Prior to the adoption of the 2018 Omnibus Plan, the Company provided share-based compensation through The Taubman Company LLC 2008 Omnibus Long-Term Incentive Plan (2008 Omnibus Plan), as amended, which expired in May 2018. 2018 Awards - TRG Profits Units During 2018, the following types of TRG Profits Units awards were granted to certain senior management employees: (1) a time-based award with a three-year cliff vesting period (Restricted TRG Profits Units); (2) a performance-based award that is based on the achievement of relative total shareholder return (TSR) over a three-year period (Relative TSR Performance-based TRG Profits Units); and (3) a performance-based award that is based on the achievement of net operating income (NOI) over a three-year period (NOI Performance-based TRG Profits Units). The maximum number of Relative TSR and NOI Performance-based TRG Profits Units are issued at grant, eventually subject to a recovery and cancellation of previously granted amounts depending on actual performance against TSR and NOI measures over the three-year performance measurement period. NOI Performance-based TRG Profits Units provide for a cap on the maximum number of units vested if a specified absolute TSR level is not achieved. Relative TSR and NOI Performance-based TRG Profits Units are generally subject to the same performance measures as the TSR-Based and NOI-Based Performance Share Units (see 2018 Awards - Other Management Employee Grants below). Despite the difference in scaling of the grant programs, the final outcome of the TSR and NOI performance measures will result in similar numbers of either TRG Units or common shares being issued at vesting under the TRG Profits Units program and the Performance Share Unit program, respectively. Each such award represents a contingent right to receive a TRG Unit upon vesting and the satisfaction of certain tax-driven requirements and, as to the TSR and NOI Performance-based TRG Profits Units, the satisfaction of certain performance-based requirements. Until vested, a TRG Profits Unit entitles the holder to only one-tenth of the distributions otherwise payable by TRG on a TRG Unit. Therefore, the Company accounts for these TRG Profits Units as participating securities in the Operating Partnership. A portion of the TRG Profits Units award represents estimated cash distributions that otherwise would have been payable during the vesting period and, upon vesting, there will be an adjustment in actual number of TRG Profits Units realized under each award to reflect the Operating Partnership's actual cash distributions during the vesting period . All TRG Profits Units issued in 2018 vest in March 2021, if continuous service has been provided, or upon retirement or certain other events (such as death or disability) if earlier. Each holder of a TRG Profits Unit will be treated as a limited partner in TRG from the date of grant. To the extent the vested TRG Profits Units have not achieved the applicable criteria for conversion to TRG Units, vesting and economic equivalence to a TRG Unit prior to the tenth anniversary of the date of grant, the awards will be forfeited pursuant to the terms of the award agreement. 2018 Awards - Other Management Employee Grants During 2018, other types of awards granted to management employees include those described below. These vest in March 2021, if continuous service has been provided, or upon retirement or certain other events (such as death or disability) if earlier. TSR - Based Performance Share Units (TSR PSU) - Each TSR PSU represents the right to receive, upon vesting, shares of common stock ranging from 0-300% of the TSR PSU based on the Company's market performance relative to that of a peer group. The TSR PSU grants include a cash payment upon vesting equal to the aggregate cash dividends that would have been paid on such shares of common stock during the vesting period. NOI - Based Performance Share Units (NOI PSU) - Each NOI PSU represents the right to receive, upon vesting, shares of common stock ranging from 0-300% of the NOI PSU based on the Company's NOI performance, as well as a cash payment upon vesting equal to the aggregate cash dividends that would have been paid on such shares of common stock during the vesting period. These awards also provide for a cap on the maximum number of units vested if a specified absolute TSR level is not achieved. Restricted Share Units (RSU) - Each RSU represents the right to receive upon vesting one share of common stock, as well as a cash payment upon vesting equal to the aggregate cash dividends that would have been paid on such shares of common stock during the vesting period . Expensed and Capitalized Costs The compensation cost charged to income for the Company’s share-based compensation plans was $2.3 million and $4.6 million for the three and six months ended June 30, 2018 , respectively. The compensation cost charged to income for the Company’s share-based compensation plans was $2.4 million and $5.5 million for the three and six months ended June 30, 2017 , respectively. Compensation cost capitalized as part of properties and deferred leasing costs was $0.2 million and $0.5 million for the three and six months ended June 30, 2018 , respectively, and an inconsequential amount and $0.3 million for the three and six months ended June 30, 2017 , respectively. Valuation Methodologies The Company estimated the grant-date fair values of share-based grants using the methods as follows. Expected volatility and dividend yields are based on historical volatility and yields of the Company’s common stock, respectively, as well as other factors. The risk-free interest rates used are based on the U.S. Treasury yield curves in effect at the grant date. The Company assumes no forfeitures for failure to meet the service requirement of Performance Share Units (PSU) or TRG Profits Units, due to the small number of participants and low turnover rate. The valuations of all grants utilized the Company's common stock price at the grant date. Common stock prices when used in valuing TRG Profits Units are further adjusted by the present value of expected differences in dividends payable on the common stock versus the distributions payable on the TRG Profits Units over the vesting period. The Company estimated the value of grants dependent on TSR performance using a Monte Carlo simulation and considering historical returns of the Company and the peer group. For awards dependent on NOI performance, the Company considers the NOI measure a performance condition under applicable accounting standards, and as such, has estimated a grant-date fair value for each of its possible outcomes. The compensation cost ultimately will be recognized equal to the grant-date fair value of the award that coincides with the actual outcome of the NOI performance. The weighted average grant-date fair value shown for NOI-dependent awards corresponds with management's current expectation of the probable outcome of the NOI performance measure. The product of the NOI-dependent awards outstanding and the grant-date fair value represents the compensation cost being recognized over the service periods. The valuations of TRG Profits Units consider the possibility that sufficient share price appreciation will not be realized, such that the conversion to TRG Units will not occur and the awards will be forfeited.

As of June 30, 2018 , there was $6.8 million of total unrecognized compensation cost related to nonvested RSU outstanding. This cost is expected to be recognized over an average period of 1.9 years . Unit Option Deferral Election Under a prior option plan, the 2008 Omnibus Plan, and the 2018 Omnibus Plan, vested unit options can be exercised by tendering mature units with a market value equal to the exercise price of the unit options. In 2002, Robert S. Taubman, the Company’s chief executive officer, exercised options for 3.0 million units by tendering 2.1 million mature units and deferring receipt of 0.9 million units under the unit option deferral election. As the Operating Partnership pays distributions, the deferred option units receive their proportionate share of the distributions in the form of cash payments. Under an amendment executed in January 2011 and subsequent deferral elections (the latest being made in September 2016), beginning in December 2022 (unless Mr. Taubman retires earlier), the deferred options units will be issued as TRG Units in five annual installments. The deferred option units are accounted for as participating securities of the Operating Partnership.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Cash Tender At the time of the Company's initial public offering and acquisition of its partnership interest in TRG in 1992, the Company entered into an agreement (the Cash Tender Agreement) with the A. Alfred Taubman Restated Revocable Trust (the Revocable Trust) and TRA Partners (now Taubman Ventures Group LLC or TVG), each of whom owned an interest in TRG, whereby each of the Revocable Trust and TVG (and/or any assignee of the Revocable Trust or TVG) has the right to tender to the Company TRG Units (provided that if the tendering party is tendering less than all of its TRG Units, the aggregate value is at least $50 million ) and cause the Company to purchase the tendered interests at a purchase price based on a market valuation of the Company on the trading date immediately preceding the date of the tender (except as otherwise provided below). TVG is controlled by a majority-in-interest among the Revocable Trust and entities affiliated with the children of A. Alfred Taubman (Robert S. Taubman, William S. Taubman, and Gayle Taubman Kalisman). At the election of the tendering party, TRG Units held by members of A. Alfred Taubman’s family and TRG Units held by entities in which his family members hold interests may be included in such a tender. The Company will have the option to pay for these interests from available cash, borrowed funds, or from the proceeds of an offering of common stock. Generally, the Company expects to finance these purchases through the sale of new shares of its common stock. The tendering partner will bear all market risk if the market price at closing is less than the purchase price and will bear the costs of sale. Any proceeds of the offering in excess of the purchase price will be for the sole benefit of the Company. The Company accounts for the Cash Tender Agreement as a freestanding written put option. As the option put price is defined by the current market price of the Company's stock at the time of tender, the fair value of the written option defined by the Cash Tender Agreement is considered to be zero . Based on a market value at June 30, 2018 of $58.76 per share for the Company's common stock, the aggregate value of TRG Units that may be tendered under the Cash Tender Agreement was $1.4 billion . The purchase of these interests at June 30, 2018 would have resulted in the Company owning an additional 28% interest in TRG. Continuing Offer The Company has made a continuing, irrevocable offer (the Continuing Offer) to all present holders of TRG Units (other than a certain excluded holder, currently TVG), permitted assignees of all present holders of TRG Units, those future holders of TRG Units as the Company may, in its sole discretion, agree to include in the Continuing Offer, all existing optionees under the previous option plan and the 2008 Omnibus Plan, and all existing and future optionees under the 2018 Omnibus Plan to exchange shares of common stock for TRG Units. Under the Continuing Offer agreement, one TRG Unit is exchangeable for one share of common stock . Upon a tender of TRG Units, the corresponding shares of Series B Preferred Stock, if any, will automatically be converted into common stock at a ratio of 14,000 shares of Series B Preferred Stock for one share of common stock . Insurance The Company carries liability insurance to mitigate its exposure to certain losses, including those relating to personal injury claims. We believe the Company's insurance policy terms and conditions and limits are appropriate and adequate given the relative risk of loss and industry practice. However, there are certain types of losses, such as punitive damage awards, which may not be covered by insurance, and not all potential losses are insured against. Hurricane Maria and The Mall of San Juan In the third quarter of 2017, The Mall of San Juan experienced certain interior water damage, impacts to exterior landscaping and signage, and significant damage to both Nordstrom and Saks Fifth Avenue as a result of Hurricane Maria. The Company has substantial insurance to cover hurricane and flood damage, as well as business and service interruption. The business interruption coverage commences at time of loss and continues for one year after the damage is fully repaired. The Company's hurricane coverage includes a single deductible of $2 million and policy limits of $900 million , all subject to various terms and conditions. During the three and six months ended June 30, 2018 , the Company recorded $0.4 million and $1.0 million , respectively, of insurance recoveries related to reimbursement of expensed costs within Nonoperating Income, Net on the Consolidated Statement of Operations and Comprehensive Income. Additionally, during the three and six months ended June 30, 2018 , the Company recognized a reduction of $1.0 million and $4.9 million , respectively, of depreciation expense relating to insurance proceeds received for property damage for which the Company took write-offs in 2017. The Company continues to assess physical loss and will update its estimates if necessary. On October 17, 2017, Plaza Internacional Puerto Rico LLC (Plaza Internacional), the owner of The Mall of San Juan (the Mall), filed a civil action in the Commonwealth of Puerto Rico Court of First Instance, San Juan Judicial Center, Superior Court, Civil No. SJ2017CV02094 (503), against Saks Fifth Avenue Puerto Rico, Inc. (Saks PR), and Saks Incorporated (Saks Inc.). The lawsuit asks the court to compel Saks PR and Saks Inc. to immediately repair and remediate the Saks Fifth Avenue store (the Store) that was damaged by Hurricane Maria on September 20, 2017, to reopen the Store on the completion of the reconstruction, and to operate the Store in accordance with the Operating Covenant contained in the Construction, Operation and Reciprocal Easement Agreement among Plaza Internacional, Saks PR, and Nordstrom Puerto Rico LLC (Nordstrom PR) made as of April 23, 2013 (the REA). In response, Saks PR and Saks Inc. filed a Counterclaim, alleging that they have no obligation to repair, remediate, reconstruct, or reopen the Store, asserting various alleged breaches of the REA and other operating agreements. Should Saks PR prevail, Nordstrom PR and other Mall tenants may then have the right to terminate their own operating covenants or leases. Plaza Internacional is vigorously prosecuting its claims and defending the Counterclaim. The outcome of the action cannot be predicted, and, at this time, the Company is unable to estimate the amount of loss that could result from an unfavorable outcome. An unfavorable outcome may have a material and adverse effect on the Company's business and its results of operations. Other See Note 5 for the Operating Partnership's guarantees of certain notes payable, including guarantees relating to Unconsolidated Joint Ventures, Note 6 for contingent features relating to certain joint venture agreements, Note 7 for contingent features relating to derivative instruments, and Note 8 for obligations under existing share-based compensation plans.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Common Share Basic earnings per common share amounts are based on the weighted average of common shares outstanding for the respective periods. Diluted earnings per common share amounts are based on the weighted average of common shares outstanding plus the dilutive effect of potential common stock. Potential common stock includes outstanding TRG Units exchangeable for common shares under the Continuing Offer (Note 9), outstanding options for TRG Units, TSR PSU, NOI PSU, Restricted and Performance-based TRG Profits Units, RSU, deferred shares under the Non-Employee Directors’ Deferred Compensation Plan, and unissued TRG Units under a unit option deferral election (Note 8). In computing the potentially dilutive effect of potential common stock, TRG Units are assumed to be exchanged for common shares under the Continuing Offer, increasing the weighted average number of shares outstanding. The potentially dilutive effects of TRG Units outstanding and/or issuable under the unit option deferral elections are calculated using the if-converted method, while the effects of other potential common stock are calculated using the treasury method. Contingently issuable shares are included in diluted earnings per common share based on the number of shares, if any, which would be issuable if the end of the reporting period were the end of the contingency period.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures This note contains required fair value disclosures for assets and liabilities remeasured at fair value on a recurring basis and financial instruments carried at other than fair value, as well as assumptions employed in deriving these fair values. Recurring Valuations Derivative Instruments The fair value of interest rate hedging instruments is the amount that the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the reporting date. The Company’s valuations of its derivative instruments are determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative, and therefore fall into Level 2 of the fair value hierarchy. The valuations reflect the contractual terms of the derivatives, including the period to maturity, and use observable market-based inputs, including forward curves. The fair values of interest rate hedging instruments also incorporate credit valuation adjustments to appropriately reflect both the Company’s own nonperformance risk and the respective counterparty's nonperformance risk. Other The Company's valuations of both its investments in an insurance deposit and in 590,124 SPG common shares utilize unadjusted quoted prices determined by active markets for the specific securities the Company has invested in, and therefore fall into Level 1 of the fair value hierarchy. In connection with the adoption of ASU No. 2016-01 on January 1, 2018 (Note 1), the Company now measures its investment in SPG common shares at fair value with changes in value recorded through net income. During the three and six months ended June 30, 2018 , the Company recorded $9.3 million of income and $0.9 million of expense, respectively in Nonoperating Income, Net on the Consolidated Statement of Operations and Comprehensive Income related to the change in fair value of its SPG common shares investment during the period. For assets and liabilities measured at fair value on a recurring basis, quantitative disclosure of the fair value for each major category of assets and liabilities is presented below: Fair Value Measurements as of June 30, 2018 Using Fair Value Measurements as of December 31, 2017 Using Description Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs SPG common shares $ 100,433 $ 101,348 Insurance deposit 9,285 16,703 Derivative interest rate contracts (Note 7) $ 8,373 $ 939 Total assets $ 109,718 $ 8,373 $ 118,051 $ 939 Derivative interest rate contracts (Note 7) $ (484 ) Total liabilities $ — $ (484 ) The insurance deposit shown above represents cash maintained in an escrow account in connection with a property and casualty insurance arrangement for the Company’s shopping centers, and is classified within Deferred Charges and Other Assets on the Consolidated Balance Sheet. Corresponding deferred revenue relating to amounts billed to tenants for this arrangement has been classified within Accounts Payable and Accrued Liabilities on the Consolidated Balance Sheet. Financial Instruments Carried at Other Than Fair Values Notes Payable The fair value of notes payable is estimated using cash flows discounted at current market rates and therefore falls into Level 2 of the fair value hierarchy. When selecting discount rates for purposes of estimating the fair value of notes payable at June 30, 2018 and December 31, 2017 , the Company employed the credit spreads at which the debt was originally issued. The estimated fair values of notes payable at June 30, 2018 and December 31, 2017 were as follows: 2018 2017 Carrying Value Fair Value Carrying Value Fair Value Notes payable, net $ 3,795,067 $ 3,688,841 $ 3,555,228 $ 3,503,071 The fair values of the notes payable are dependent on the interest rates used in estimating the values. An overall 1% increase in interest rates employed in making these estimates would have decreased the fair values of the debt shown above at June 30, 2018 by $141.3 million or 3.8% . Cash Equivalents and Notes Receivable The fair value of cash equivalents and notes receivable approximates their carrying value due to their short maturity. The fair value of cash equivalents is derived from quoted market prices and therefore falls into Level 1 of the fair value hierarchy. The fair value of notes receivable is estimated using cash flows discounted at current market rates and therefore falls into Level 2 of the fair value hierarchy. See Note 7 regarding additional information on derivatives.

Income taxes paid for the six months ended June 30, 2018 and 2017 were $0.4 million and $1.7 million , respectively. Other non-cash additions to properties during the six months ended June 30, 2018 and 2017 were $81.3 million and $99.2 million , respectively, and primarily represent accrued construction and tenant allowance costs. Reconciliation of Cash, Cash Equivalents, and Restricted Cash On January 1, 2018, the Company adopted ASU No. 2016-18, "Statement of Cash Flows - Restricted Cash", which changed the presentation of restricted cash and changes in restricted cash on the Consolidated Statement of Cash Flows (Note 1). The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheet that sum to the total of the same such amounts shown on the Consolidated Statement of Cash Flows.

New Accounting Pronouncements, Policy [Abstract]
New Accounting Pronouncement, Policy [Policy Text Block]	New Accounting Pronouncement In February 2016, the FASB issued ASU No. 2016-02, "Leases", which provides for significant changes to the current lease accounting standard. The primary objectives of this ASU is to address off-balance-sheet financing related to operating leases and to introduce a new lessee model that brings substantially all leases onto the balance sheet. ASU No. 2016-02 is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2018. The Company expects to adopt the new standard on its effective date. The Company is currently evaluating the application of this ASU and its effect on the Company’s financial position and results of operations. From initial implementation efforts, the Company preliminarily expects the most significant impacts of adoption to include the potential need to expense certain internal leasing costs currently being capitalized, including costs associated with the Company's leasing department, and the recognition of lease obligations and right-of-use assets for ground and office leases under which the Company or its ventures are the lessee. In July 2018, the FASB issued ASU No. 2018-11, which includes a practical expedient that allows lessors to not separate non-lease components from the associated lease component. This provides the Company with the option of not bifurcating certain common area maintenance recoveries as a non-lease component, if certain requirements are met. The Company has not completed its budgeting for calendar 2019 and therefore does not yet have specific expectations for leasing costs to be expensed pursuant to ASU No. 2016-02. The actual amount of such costs will ultimately depend on personnel levels, compensation structure, and the results of leasing activities. However, as part of its implementation, the Company is analyzing the impact the standard would have had in prior periods if it had been applied. For the year ended December 31, 2017, the Company's share of capitalized leasing and tenant coordination costs was approximately $11 million . If the accounting under ASU No. 2016-02 had been applied, the Company expects that it would have continued to capitalize approximately $5 million of leasing and tenant coordination costs and additionally expensed approximately $6 million in leasing costs.

Accounting Policies [Abstract]
Accounting Changes [Text Block]	Change in Accounting Policies Recognition and Measurement of Financial Assets and Financial Liabilities On January 1, 2018, the Company adopted Accounting Standards Update (ASU) No. 2016-01, "Recognition and Measurement of Financial Assets and Financial Liabilities", which changed certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. As such, the Company now measures equity investments at fair value through net income, except for those that result in consolidation or are accounted for under the equity method. Upon adoption, the Company applied the modified-retrospective approach and recorded a one-time cumulative-effect adjustment to reclassify $1.0 million of historical unrealized gains on the fair value adjustments as of December 31, 2017 of its 590,124 Simon Property Group (SPG) common shares investment from Accumulated Other Comprehensive Income (Loss) (AOCI) to Dividends in Excess of Net Income on the Company's Consolidated Balance Sheet. Beginning in January 2018, changes in the fair value of any outstanding SPG common shares are being recorded in Nonoperating Income, Net on the Company's Consolidated Statement of Operations and Comprehensive Income (Note 11). Cash Flow Statement Presentation On January 1, 2018, the Company adopted ASU No. 2016-18, "Statement of Cash Flows - Restricted Cash", which changed the presentation of restricted cash and changes in restricted cash on the Consolidated Statement of Cash Flows. As a result, the Company changed the presentation of its Consolidated Statement of Cash Flows for both the six months ended June 30, 2018 and 2017 to include restricted cash. Refer to Note 13 for a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheet that sum to the total of the same such amounts on the Consolidated Statement of Cash Flows. In connection with the adoption this ASU, the Company revisited its accounting policies and presentation in regards to cash, deposits, and other investments subject to restrictions. In doing so, the Company reclassified $119.2 million from Deferred Charges and Other Assets to Restricted Cash on the Consolidated Balance Sheet as of December 31, 2017, to conform to current year classifications. On January 1, 2018, the Company adopted ASU No. 2016-15, "Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments", which clarified the presentation of certain cash receipts and payments, including the classification of distributions received from equity method investees, on the Consolidated Statement of Cash Flows. In connection with the adoption of this ASU on January 1, 2018, the Company re-evaluated its current methodology and retrospectively changed the presentation of the Consolidated Statement of Cash Flows for the six months ended June 30, 2017 to re-classify prior year balances to correspond with current year classifications, specifically related to distributions received from equity method investees.
Revenue from Contract with Customer [Text Block]	Adoption of Accounting Standards Codification (ASC) Topic 606 ("Revenue from Contracts with Customers") General On January 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers. ASC Topic 606 provides a single comprehensive model to use in accounting for revenue arising from contracts with customers, and gains and losses arising from transfers of non-financial assets including sales of property and equipment, real estate, and intangible assets. The Company adopted ASC Topic 606 for all applicable contracts using the modified retrospective method, which would have required a cumulative-effect adjustment, if any, as of the date of adoption. The adoption of ASC Topic 606 did not have a material impact on the Company's consolidated financial statements as of the date of adoption, and therefore a cumulative-effect adjustment was not required. The Company applied ASC Topic 606 using certain practical expedients. As a result of this election, the Company will not disclose the aggregate amount of the transaction price for unsatisfied, or partially unsatisfied, performance obligations for all contracts with an original expected length of one year or less and management contracts for which the Company recognizes revenue based on its right to invoice for management, leasing, and development services performed. Refer to the "Nature of Services and Performance Obligations" section for further discussion of these services. Disaggregation of Revenue The nature, amount, timing, and uncertainty of individual types of revenues may be affected differently by economic factors. Under ASC Topic 606, the Company is required to disclose a disaggregation of its revenues derived from contracts from customers that considers economic differences between revenue types. The following table summarizes the Company’s disaggregation of consolidated revenues for this purpose. Three Months Ended June 30 Six Months Ended June 30 2018 2017 2018 2017 Expense recoveries $ 50,553 $ 49,413 $ 102,081 $ 102,425 Shopping center and other operational revenues (1) 10,817 10,860 21,637 18,504 Management, leasing, and development services 826 1,375 1,620 2,292 Total revenue from contracts with customers $ 62,196 $ 61,648 $ 125,338 $ 123,221 (1) Represents consolidated Other revenue reported on the Consolidated Statement of Operations and Comprehensive Income excluding lease cancellation income. Nature of Services and Performance Obligations Expense recoveries revenue represents reimbursements from mall tenants for (1) services performed by the Company to the benefit of all mall tenants and the property as a whole for common area maintenance, (2) insurance, property taxes, and utilities, and (3) promotion and other miscellaneous charges. As these expense recoveries are provided for under tenant lease agreements, these revenues will not be evaluated under ASC Topic 606 until the Company's adoption of ASU No. 2016-02, Leases, which will be adopted as of January 1, 2019. Shopping center and other operational revenues represent a collection of non-core revenue streams that are generated through the course of owning and operating a shopping center, including sponsorship, parking, and storage income, as well as revenues from food and beverage operations. The contracts for these revenue streams are predominately short-term in nature and individually do not contain more than one performance obligation. The Company satisfies its performance obligations related to shopping center and other operational revenues either over time or at a point in time, depending on the specific nature of the revenue generating activity. For performance obligations that are satisfied at a point in time, including food and beverage and parking income, the control of the good or service is immediately transferred to the customer upon completion of the performance obligation. Payment terms related to shopping center and other operational revenues vary depending on the nature of the agreement, however, payment is generally due directly upon the satisfaction of the related performance obligation. Management, leasing, and development services revenue represents income from various services performed by the Company for its third party customers, as provided for under management agreements. These services typically generate fees that are based on operating results of the shopping centers, the execution and opening of mall tenants, and/or the successful completion of other agreed-upon services. As each management agreement provides for a variety of services, significant judgment is required to identify multiple performance obligations. The standalone selling price of each performance obligation is determined based on the terms of the management agreement and the specific services being rendered. Each performance obligation is considered to be satisfied over time as services are rendered. The related revenue is recognized upon billing, as the amounts invoiced generally correspond directly with the value the customer is receiving from the services. Customers are invoiced on quarterly basis and payment is generally due within 30 days of each calendar quarter. Information about Contract Balances and Unsatisfied Performance Obligations Contract assets exist when the Company has a right to payment for services rendered that remains conditional on factors other than the passage of time. Similarly, contract liabilities are incurred when customers prepay for services to be rendered. Certain revenue streams within shopping center and other operational revenues may give rise to contract assets and liabilities.

Profits Units [Member]
Summary of non-option activity, additional disclosures [Abstract]
Awards under the Omnibus Plan			represents a contingent right to receive a TRG Unit upon vesting and the satisfaction of certain tax-driven requirements and, as to the TSR and NOI Performance-based TRG Profits Units, the satisfaction of certain performance-based requirements. Until vested, a TRG Profits Unit entitles the holder to only one-tenth of the distributions otherwise payable by TRG on a TRG Unit. Therefore, the Company accounts for these TRG Profits Units as participating securities in the Operating Partnership. A portion of the TRG Profits Units award represents estimated cash distributions that otherwise would have been payable during the vesting period and, upon vesting, there will be an adjustment in actual number of TRG Profits Units realized under each award to reflect the Operating Partnership's actual cash distributions during the vesting period
