Its Properties are located in 24 states, but are primarily in the southeastern and midwestern United States. CBL conducts substantially all of its business through CBL & Associates Limited Partnership (the "Operating Partnership"), which is a variable interest entity ("VIE"). The Operating Partnership consolidates the financial statements of all entities in which it has a controlling financial interest or where it is the primary beneficiary of a VIE. As of December 31, 2020, the Operating Partnership owned interests in the following Properties: All Other Properties Malls (1) Associated Centers Community Centers Office Buildings and Other Total Consolidated Properties 51 20 1 4 (2) 76 Unconsolidated Properties (3) 10 3 5 4 22 Total 61 23 6 8 98 (1) Category consists of regional malls, open-air centers and outlet centers (including one mixed-use center) (the "Malls"). (2) Includes CBL's two corporate office buildings. (3) The Operating Partnership accounts for these investments using the equity method because one or more of the other partners have substantive participating rights. The Malls, All Other Properties ("Associated Centers, Community Centers, Office Buildings and Other") and the Construction Properties are collectively referred to as the “Properties” and individually as a “Property.” CBL is the 100% owner of two qualified REIT subsidiaries, CBL Holdings I, Inc. and CBL Holdings II, Inc. At December 31, 2020, CBL Holdings I, Inc., the sole general partner of the Operating Partnership, owned a 1.0% general partner interest in the Operating Partnership and CBL Holdings II, Inc. owned a 96.5% limited partner interest for a combined interest held by CBL of 97.5%. Historically, the noncontrolling interest in the Operating Partnership has been held by CBL & Associates, Inc., its shareholders and affiliates and certain senior officers of the Company (collectively "CBL's Predecessor"), all of which contributed their interests in certain real estate properties and joint ventures to the Operating Partnership in exchange for a limited partner interest when the Operating Partnership was formed in November 1993, and by various third parties. During 2020, the Company issued 20,956,110 As used herein, the term "Company" includes CBL & Associates Properties, Inc. and its subsidiaries, including CBL & Associates Limited Partnership and its subsidiaries, unless the context indicates otherwise. The term "Operating Partnership" refers to CBL & Associates Limited Partnership and its subsidiaries. The Operating Partnership conducts the Company's property management and development activities through its wholly owned subsidiary, CBL & Associates Management, Inc. (the “Management Company"), to comply with certain requirements of the Internal Revenue Code.

COVID-19 The COVID-19 pandemic has had, and likely will continue to have, repercussions across local, national and global economies and financial markets. COVID-19 has impacted all states where the Company’s tenants operate their businesses or where the Company’s properties are located and measures taken to prevent or remediate COVID-19, including “shelter-in place” or “stay-at-home” orders or other quarantine mandates issued by local, state or federal authorities, have had an adverse effect on its business and the businesses of its tenants. The full extent of the adverse impact on, among other things, the Company’s results of operations, liquidity (including its ability to access capital markets), the possibility of future impairments of long-lived assets or its investments in unconsolidated joint ventures, its compliance with debt covenants, its ability to renew and re-lease its leased space, the outlook for the retail environment, potential bankruptcies or other store closings and its ability to develop, acquire, dispose or lease properties, is unknown and will depend on future developments, which are highly uncertain and cannot be predicted. State and local governments and other authorities are in varying stages of lifting or modifying some of the measures used to mitigate or control the spread of the virus. Even though vaccines have started to be administered, the COVID-19 pandemic could worsen at any time, which could cause new or more restrictive measures to be implemented to prevent the spread of the virus. Tenants and customers have gradually adapted to current conditions with services such as curbside pickup and increased consumer risk-tolerance, but there is no guarantee that retail will return to levels seen prior to the pandemic. The Company has experienced, and expects to continue to experience, a material adverse impact on its revenues, results of operations, and cash flows into 2021. The situation is rapidly changing and additional impacts to the business may arise that the Company is not aware of currently.

Chapter Eleven Cases And Ability To Continue As Going Concern [Abstract]
Chapter 11 Cases and Ability to Continue as a Going Concern	NOTE 2. CHAPTER 11 CASES AND ABILITY TO CONTINUE AS A GOING CONCERN Voluntary Reorganization under Chapter 11 On August 18, 2020, the Company entered into a Restructuring Support Agreement, (the “Original RSA”) with certain beneficial owners and/or investment advisors or managers of discretionary funds, accounts or other entities for the holders of beneficial owners (the “Consenting Noteholders”) representing in excess of 62%, including joining noteholders pursuant to joinder agreements, of the aggregate principal amount of the $450,000 of senior unsecured notes issued by the Operating Partnership in November 2013 that bear interest at 5.25% and mature on December 1, 2023 (the “2023 Notes”), the $300,000 of senior unsecured notes issued by the Operating Partnership in October 2014 that bear interest at 4.60% and mature on October 15, 2024 (the “2024 Notes”) and the $625,000 of senior unsecured notes issued by the Operating Partnership in December 2016 and September 2017 that bear interest at 5.95% and mature on December 15, 2026 (the “2026 Notes” and, collectively with the 2023 Notes and 2024 Notes, the "Notes"). On October 28, 2020, the Operating Partnership was notified by the administrative agent and lenders that they elected to exercise their rights pursuant to the terms of the secured credit facility to (i) require that rents payable by tenants at the properties that are collateral to the secured credit facility be paid directly to the administrative agent and (ii) exercise all voting rights and other ownership rights in respect of all the equity interests in the subsidiaries of the Operating Partnership that are guarantors of the secured credit facility. Beginning on November 1, 2020 (the “Commencement Date”), CBL and the Operating Partnership, together with certain of its direct and indirect subsidiaries (collectively, the “Debtors”), filed voluntary petitions (the “Chapter 11 Cases”) under chapter 11 of title 11 (“Chapter 11”) of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”) In re CBL & Associates Properties, Inc., et al. , Case No. 20-35226 The filing of the Chapter 11 Cases constituted an event of default that results in the automatic acceleration of certain monetary obligations to be immediately due and payable with respect to the secured credit facility and the senior unsecured notes. On November 2, 2020, the Company filed an adversary proceeding in the Bankruptcy Court seeking among other things, a t emporary r estraining o rder (the “Order”) and for a p reliminary i njunction to enjoin, pending a determination of the parties’ rights, the administrative agent or any of its officers, agents, servants, attorneys and successors from taking any action to exercise any and all remedies under the terms of the secured credit facility or other agreements as a result of the e vents of d efault asserted by the administrative a gent, or any other right or remedy that would otherwise accompany the occurrence of an e vent of d efault, including without limitation, any rights of acceleration under the terms of the secured credit facility , rights flowing from the n otice of a cceleration, right s exercised pursuant to the Notice of Exercise or any other rights or remedies properly exercisable solely upon an actual or determined e vent of d efault . On November 2, 2020, the Bankruptcy Court granted the Order , and the Bankruptcy Court took up the other pending claims during the adversarial proceeding, which has now been stayed pending the confirmation of the Company’s p lan, discussed below. Following the Commencement Date, the Bankruptcy Court entered certain interim and final orders facilitating the Debtors’ operational transition into Chapter 11. These orders authorized the Debtors to, among other things, pay certain prepetition employee expenses and benefits, use their existing cash management system, maintain and administer customer programs, pay certain critical service providers, honor insurance-related obligations, and pay certain prepetition taxes and related fees on a final basis. After engaging in negotiations in a Bankruptcy Court-ordered mediation, on March 21, 2021 (the “Agreement Effective Date”), the Company entered into the First Amended and Restated Restructuring Support Agreement (the “Amended RSA”), with the Consenting Noteholders in excess of 69% (including joinders) of the aggregate principal amount of the Notes and certain lenders party to the Company’s secured credit facility who hold in the aggregate in excess of 96% (including joinders) of the aggregate outstanding principal amount of debt under the secured credit facility (the “Consenting Bank Lenders” and together with the Consenting Noteholders, the “Consenting Stakeholders”). The Amended RSA amends and restates the Original RSA and sets forth, subject to certain conditions, the commitments to and obligations of, on the one hand, the Company, and on the other hand, the Consenting Noteholders and Consenting Bank Lenders, in connection with the restructuring transactions (the “Restructuring Transactions”) set forth in the Amended RSA and the plan term sheet attached as Exhibit B to the Amended RSA (the “Plan Term Sheet”). The Amended RSA contemplates that the restructuring and recapitalization of the Debtors will occur through a joint plan of reorganization in the Chapter 11 Cases (the “Amended Plan”). The Amended RSA requires that the Company file the Amended Plan and related disclosure statement no later than 25 days following the Agreement Effective Date and under the Amended RSA the Company must seek to have the Amended Plan confirmed and declared effective no later than November 1, 2021. Before a Bankruptcy Court will confirm the Amended Plan, the Bankruptcy Code requires at least one “impaired” class of claims votes to accept the Amended Plan. A class of claims votes to “accept” the Amended Plan if voting creditors that hold a majority in number and two-thirds in amount of claims in that class approve the Amended Plan. The Amended RSA requires the Consenting Stakeholders vote in favor of and support the Amended Plan. As of the date hereof, the Consenting Bank Lenders and Consenting Noteholders each represent the requisite amount of claims necessary to accept the Amended Plan in each of their respective classes. For the foregoing reasons, among others, the Debtors believe that they will be able to confirm the Amended Plan in the Chapter 11 Cases. The Amended RSA provides that the ongoing litigation between the Company and the lenders of the Company’s secured credit facility (the “Bank Lenders”) arising from the prepetition enforcement actions taken by the Bank Lenders is stayed and is to be dismissed upon the Bankruptcy Court’s approval of the Amended Plan. Under the Amended RSA, the proposed Amended Plan will provide for the elimination of more than $1,681,900 of debt and preferred obligations as well as a significant reduction in interest expense. In exchange for their approximately $1,375,000 in principal amount of senior unsecured notes and $133,000 in principal amount of the secured credit facility, Consenting Noteholders and other noteholders will receive, in the aggregate, $95,000 in cash, $555,000 of new senior secured notes, of which up to $100,000, upon election by the Consenting Noteholders, may be received in the form of new convertible secured notes and 89% in common equity of the newly reorganized Company. Certain Consenting Noteholders will also provide up to $50,000 of new money in exchange for additional convertible secured notes. The transactions outlined in the Amended RSA will be implemented in the Chapter 11 Cases and pursuant to the Amended Plan. . The Company cannot predict the ultimate outcome of its Chapter 11 Cases at this time. For the duration of the Company’s Chapter 11 proceedings, the Company’s operations and ability to develop and execute its business plan are subject to the risks and uncertainties associated with the Chapter 11 process. As a result of these risks and uncertainties, the amount and composition of the Company’s assets, liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 proceedings, and the description of the Company’s operations, properties and liquidity and capital resources included in this annual report may not accurately reflect its operations, properties and liquidity and capital resources following the Chapter 11 process. In particular, subject to certain exceptions, under the Bankruptcy Code, the Debtors may assume, assume and assign or reject executory contracts and unexpired leases subject to the approval of the Bankruptcy Court and certain other conditions. Generally, the rejection of an executory contract or unexpired lease is treated as a prepetition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves the Debtors of performing their future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a prepetition general unsecured claim for damages caused by such deemed breach subject, in the case of the rejection of unexpired leases of real property, to certain caps on damages. Counterparties to such rejected contracts or leases may assert unsecured claims in the Bankruptcy Court against the applicable Debtor’s estate for such damages. Generally, the assumption or assumption and assignment of an executory contract or unexpired lease requires the Debtors to cure existing monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance thereunder. Accordingly, any description of an executory contract or unexpired lease with the Debtors in this annual report, including where applicable a quantification of the Company’s obligations under any such executory contract or unexpired lease with the Debtors is qualified by any overriding rights the Company has under the Bankruptcy Code. Further, nothing herein is or shall be deemed an admission with respect to any claim amounts or calculations arising from the assumption, assumption and assignment or rejection of any executory contract or unexpired lease and the Debtors expressly preserve all of their rights with respect thereto. Liquidity and Going Concern Considerations In accordance with the accounting guidance related to the presentation of financial statements, when preparing financial statements for each annual and interim reporting period, management evaluates whether there are conditions or events that, when considered in the aggregate, 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. In making its assessment, management considered the Company’s current financial condition and liquidity sources, as well as the status of the Chapter 11 Cases. The filing of the Chapter 11 Cases by the Debtors constituted an event of default that results in the automatic acceleration of certain monetary obligations to be immediately due and payable with respect to the secured credit facility and the senior unsecured notes. The filing of the Chapter 11 Cases also constituted an event of default with respect to certain property-level debt of the Operating Partnership’s subsidiaries, which may result in acceleration of the outstanding principal and other sums due. See Note 8 and Note 9 for further discussion. Given the acceleration of the secured credit facility, the senior unsecured notes and certain property-level debt, as well as the inherent risks, unknown results and inherent uncertainties associated with the bankruptcy process and the direct correlation between these matters and the Company’s ability to satisfy its financial obligations that may arise Delisting of Common Stock and Depositary Shares On November 2, 2020, the NYSE announced that (i) it had suspended trading in the Company’s stock and (ii) it had determined to commence proceedings to delist the Company’s common stock, as well as the depositary shares each representing a 1/10th fractional share of the Company’s 7.375% Series D Cumulative Redeemable Preferred Stock (“Series D Preferred Stock”) and the depositary shares each representing a 1/10th fractional share of the Company’s 6.625% Series E Cumulative Redeemable Preferred Stock (“Series E Preferred Stock”), due to such securities no longer being suitable for listing based on “abnormally low” trading price levels, pursuant to Section 802.01D of the NYSE Listed Company Manual. The Company has appealed this decision in accordance with NYSE rules, and the appeal is still in process. In the meantime, effective November 3, 2020, the Company’s common stock and the depositary shares representing fractional interests in its Series D Preferred Stock and Series E Preferred Stock began trading on the OTC Markets, operated by the OTC Markets Group, Inc., under the symbols “CBLAQ”, “CBLDQ” and “CBLEQ”, respectively. A delisting of the Company’s common stock from the NYSE could negatively impact it by, among other things, reducing the trading liquidity of, and the market price for, its common stock. Prepetition Charges Expenses that were realized or incurred prior to November 1, 2020 in relation to the Company’s efforts to restructure its corporate-level debt are recorded in the line item “Prepetition charges” in the Company’s consolidated statements of operations. The $23,883 of prepetition charges primarily consists of professional fees. Reorganization Items Any expenses, gains and losses that are realized or incurred as of or subsequent to November 1, 2020, the petition date, and as a direct result of the Chapter 11 Cases, are recorded in the line item “Reorganization items” in the Company’s consolidated statements of operations. The $35,977 of reorganization items consists of $10,347 in professional fees, $25,294 of unamortized deferred financing costs and debt discounts related to the secured credit facility and the senior unsecured notes, as well as $336 of U.S. Trustee fees. Liabilities Subject to Compromise The Company has reclassified $2,551,490 to the line item “Liabilities subject to compromise” in the Company’s consolidated balance sheets. These liabilities are reported at the amounts expected to be allowed as claims by the Bankruptcy Court, although they may be settled for less. As of December 31, 2020, the liabilities subject to compromise consisted of $1,375,000 related to the senior unsecured notes, $675,926 related to the secured line of credit, $438,750 related to the secured term loan, $57,644 in unpaid accrued interest as of the Commencement Date and $4,170 of prepetition unsecured or under secured liabilities. The contractual interest expense on the senior unsecured notes and secured credit facility is in excess of recorded interest expense by $30,084 for the year ended December 31, 2020. This excess contractual interest expense is not included as interest expense in the consolidated statements of operations for the year ended December 31, 2020 because the Company discontinued accruing interest on the senior unsecured notes and the secured credit facility subsequent to the Commencement Date in accordance with ASC 852, which limits the recognition of interest expense during a bankruptcy proceeding to only amounts that will be paid during the bankruptcy proceeding or that are probable of becoming allowed claims. The Company has not made any interest payments on its senior unsecured notes or its secured credit facility since the Chapter 11 Cases commenced on November 1, 2020. Condensed combined financial statement information of the Debtors is as follows: Condensed Combined Financial Statements – Debtors (Debtors-In-Possession) Condensed Combined Balance Sheet December 31, 2020 ASSETS: Investment in real estate assets $ 4,056,257 Accumulated depreciation (1,544,800 ) 2,511,457 Developments in progress 27,853 Net investment in real estate assets 2,539,310 Available-for-sale securities - at fair value (amortized cost of $233,052) 233,071 Cash and cash equivalents 46,346 Restricted Cash 29,834 Intercompany due from non-debtor entities 76,095 Other assets 140,241 Total assets $ 3,064,897 LIABILITIES, REDEEMABLE NONCONTROLLING INTERESTS AND EQUITY: Other liabilities $ 102,910 Intercompany due to non-debtor entities 5,062 Total liabilities not subject to compromise 107,972 Liabilities subject to compromise 2,551,490 Redeemable noncontrolling interests (2,786 ) Shareholders' equity 411,605 Noncontrolling interests (3,384 ) Total liabilities and owners’ equity $ 3,064,897 Condensed Combined Statement of Operations For the Period November 1, 2020 to December 31, 2020 Total revenues $ 70,845 Depreciation and amortization (23,064 ) Operating expenses (22,040 ) Interest and other income 1,705 Interest expense (unrecognized contractual interest expense was $30,084 for the year ended December 31, 2020) (760 ) Reorganization items (35,977 ) Gain on sales of real estate assets 1,988 Income tax benefit 354 Net loss $ (6,949 ) Condensed Combined Statement of Cash Flows CASH FLOWS FROM OPERATING ACTIVITIES: For the Period November 1, 2020 to December 31, 2020 Net loss $ (6,949 ) Adjustments to reconcile net loss to net cash provided by operating activities: Reorganization items (non-cash) 25,294 Other assets and liabilities, net 26,885 Net cash provided by operating activities 45,230 CASH FLOWS FROM INVESTING ACTIVITIES: Purchase of available-for-sale securities (81,276 ) Changes in other assets 2,506 Net cash used in investing activities (78,770 ) CASH FLOWS FROM FINANCING ACTIVITIES: Net distributions from non-Debtor subsidiaries 8,621 Other financing activities 104 Net cash provided by financing activities 8,725 NET CHANGE IN CASH, CASH EQUIVALENTS AND RESTRICTED CASH (24,815 ) CASH, CASH EQUIVALENTS AND RESTRICTED CASH, beginning of period 100,995 CASH, CASH EQUIVALENTS AND RESTRICTED CASH, end of period $ 76,180 Reconciliation from consolidated statement of cash flows to consolidated balance sheet: Cash and cash equivalents $ 46,346 Restricted cash 29,834 CASH, CASH EQUIVALENTS AND RESTRICTED CASH, end of period $ 76,180 SUPPLEMENTAL INFORMATION Cash paid for reorganization items $ 301

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation This Form 10-K provides separate consolidated financial statements for the Company and the Operating Partnership. Due to the Company's ability as general partner to control the Operating Partnership, the Company consolidates the Operating Partnership within its consolidated financial statements for financial reporting purposes. The notes to consolidated financial statements apply to both the Company and the Operating Partnership, unless specifically noted otherwise. The accompanying consolidated financial statements include the consolidated accounts of the Company, the Operating Partnership and their wholly owned subsidiaries, as well as entities in which the Company has a controlling financial interest or entities where the Company is deemed to be the primary beneficiary of a VIE. For entities in which the Company has less than a controlling financial interest or entities where the Company is not deemed to be the primary beneficiary of a VIE, the entities are accounted for using the equity method of accounting. Accordingly, the Company's share of the net earnings or losses of these entities is included in consolidated net income (loss). The accompanying consolidated financial statements have been prepared in accordance with GAAP. All intercompany transactions have been eliminated. Accounting Guidance Adopted Description Expected Adoption Date & Application Method Financial Statement Effect and Other Information Accounting Standards Update (“ASU”) 2016-13, Measurement of Credit Losses on Financial Instruments January 1, 2020 - Modified Retrospective The guidance replaced the current incurred loss impairment model, which reflects credit events, with a current expected credit loss model, which recognizes an allowance for credit losses based on an entity’s estimate of contractual cash flows not expected to be collected. The Company has determined that its available-for-sale debt securities, guarantees, mortgage and other notes receivable and receivables within the scope of ASC 606 fall under the scope of this standard. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-13, Fair Value Measurement January 1, 2020 - Prospective The guidance eliminates, adds and modifies certain disclosure requirements for fair value measurements. Entities no longer are required to disclose the amount of and reasons for transfers between Level 1 and 2 of the fair value hierarchy, but public companies are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract January 1, 2020 - Prospective The guidance addresses diversity in practice in accounting for the costs of implementation activities in a cloud computing arrangement that is a service contract. Under the guidance, the Company is to follow Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize and which to expense. The guidance also requires an entity to expense capitalized implementation costs over the term of the hosting arrangement and include that expense in the same line item as the fees associated with the service element of the arrangement. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. Lease Modification Q&A April 1, 2020 – Prospective In April 2020, the FASB issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance related to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under Topic 842, Leases The Company has elected to apply the relief provided under the Lease Modification Q&A and will avail itself of the election to avoid performing a lease by lease analysis for the lease concessions that were (1) granted as relief due to the COVID-19 pandemic and (2) result in the cash flows remaining substantially the same or less than the original contract. The Lease Modification Q&A had a material impact on the Company’s consolidated financial statements as of and for the year ended December 31, 2020. However, its future impact to the Company is dependent upon the extent of lease concessions granted to tenants as a result of the COVID-19 pandemic in future periods and the elections made by the Company at the time of entering such concessions. The Lease Modification Q&A allows the Company to determine accounting policy elections at a disaggregated level, and the elections should be applied consistently by either the type of concession, underlying asset class or on another reasonable basis. As a result, the Company has made the following policy elections based on the type of concession agreed to with the respective tenant. Rent Deferrals The Company will account for rental deferrals using the receivables model as described within the Lease Modification Q&A. Under the receivables model, the Company will continue to recognize lease revenue in a manner that is unchanged from the original lease agreement and continue to recognize lease receivables and rental revenue during the deferral period. Rent Abatements The Company will account for rental abatements using the negative variable income model as described within the Lease Modification Q&A. Under the negative variable income model, the Company will recognize negative variable rent for the current period reduction of rental revenue associated with any lease concessions it provide s . At December 31, 2020, the Company’s receivables included $18,526 related to receivables that had been deferred and are to be repaid generally throughout 2021, and extending for a portion of 2022. The Company granted abatements of $25,439 during the year ended December 31, 2020. The Company continues to assess rent relief requests from its tenants but is unable to predict the resolution or impact of these discussions. For agreements that are currently under negotiation, the Company does not expect the impact to be material. Accounting Guidance Not Yet Adopted Description Financial Statement Effect and Other Information ASU 2020-04, Reference Rate Reform On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting Real Estate Assets The Company capitalizes predevelopment project costs paid to third parties. All previously capitalized predevelopment costs are expensed when it is no longer probable that the project will be completed. Once development of a project commences, all direct costs incurred to construct the project, including interest and real estate taxes, are capitalized. Additionally, certain general and administrative expenses are allocated to the projects and capitalized based on the amount of time applicable personnel work on the development project. Ordinary repairs and maintenance are expensed as incurred. Major replacements and improvements are capitalized and depreciated over their estimated useful lives. All acquired real estate assets have been accounted for using the acquisition method of accounting and accordingly, the results of operations are included in the consolidated statements of operations from the respective dates of acquisition. The Company allocates the purchase price to (i) tangible assets, consisting of land, buildings and improvements, as if vacant, and tenant improvements, and (ii) identifiable intangible assets and liabilities, generally consisting of above-market leases, in-place leases and tenant relationships, which are included in intangible lease assets and other assets, and below-market leases, which are included in accounts payable and accrued liabilities. The Company uses estimates of fair value based on estimated cash flows, using appropriate discount rates, and other valuation techniques to allocate the purchase price to the acquired tangible and intangible assets. Liabilities assumed generally consist of mortgage debt on the real estate assets acquired. Assumed debt is recorded at its fair value based on estimated market interest rates at the date of acquisition. The Company expects its future acquisitions will be accounted for as acquisitions of assets in which related transaction costs will be capitalized. Depreciation is computed on a straight-line basis over estimated lives of 40 years for buildings, 10 to 20 years for certain improvements and 7 to 10 years for equipment and fixtures. Tenant improvements are capitalized and depreciated on a straight-line basis over the term of the related lease. Lease-related intangibles from acquisitions of real estate assets are generally amortized over the remaining terms of the related leases. The amortization of above- and below-market leases is recorded as an adjustment to rental revenue, while the amortization of all other lease-related intangibles is recorded as amortization expense. Any difference between the face value of the debt assumed and its fair value is amortized to interest expense over the remaining term of the debt using the effective interest method. The Company’s intangibles and their balance sheet classifications as of December 31, 2020 and 2019, are summarized as follows: December 31, 2020 December 31, 2019 Cost Accumulated Amortization Cost Accumulated Amortization Intangible lease assets and other assets: Above-market leases $ 18,416 $ (16,395 ) $ 21,098 $ (18,559 ) In-place leases 59,472 (53,790 ) 66,309 (58,559 ) Tenant relationships 34,630 (7,909 ) 38,880 (10,834 ) Accounts payable and accrued liabilities: Below-market leases 42,274 (36,224 ) 46,554 (38,052 ) These intangibles are related to specific tenant leases. Should a termination occur earlier than the date indicated in the lease, the related unamortized intangible assets or liabilities, if any, related to the lease are recorded as expense or income, as applicable. The total net amortization expense of the above intangibles was $1,460, $4,506 and $13,282 in 2020, 2019 and 2018, respectively. The estimated total net amortization expense for the next five succeeding years is $1,326 in 2021, $1,071 in 2022, $872 in 2023, $854 in 2024 and $817 in 2025. Total interest expense capitalized was $1,640, $2,504 and $3,225 in 2020, 2019 and 2018, respectively. Accounts Receivable Receivables include amounts billed and currently due from tenants pursuant to lease agreements and receivables attributable to straight-line rents associated with those lease agreements. Individual leases where the collection of rents is in dispute are assessed for collectability based on management’s best estimate of collection considering the anticipated outcome of the dispute. Individual leases that are not in dispute are assessed for collectability and upon the determination that the collection of rents over the remaining lease term is not probable, accounts receivable are reduced as an adjustment to rental revenues. Revenue from leases where collection is deemed to be less than probable is recorded on a cash basis until collectability is determined to be probable. Further, management assesses whether operating lease receivables, at a portfolio level, are appropriately valued based upon an analysis of balances outstanding, historical collection levels and current economic trends. An allowance for the uncollectable portion of the portfolio is recorded as an adjustment to rental revenues. Management’s estimate of the collectability of accounts receivable from tenants is based on the best information available to management at the time of evaluation. The duration of the COVID-19 pandemic and its impact on the Company’s tenants’ ability to pay rents has caused uncertainty in the Company’s ongoing ability to collect rents when due. Considering the potential impact of these uncertainties, management’s collection assessment also took into consideration the type of retailer, billing disputes, lease negotiation status and executed deferral or abatement agreements, as well as recent rent collection experience and tenant bankruptcies based on the best information available to management at the time of evaluation. For the year ended December 31, 2020 and 2019, the Company recorded $48,240 and $3,463, respectively, associated with uncollectable revenues, which includes $5,603 for straight line rent receivables for the year ended December 31, 2020. The following table sets forth the activity for the Company’s allowance for doubtful accounts: Year Ended December 31, 2019 2018 (1) Tenant receivables - allowance for doubtful accounts: Balance, beginning of year $ 2,337 $ 2,011 Additions in allowance charged to expense — 4,817 Bad debts charged against allowance (2,337 ) (4,491 ) Balance, end of year $ — $ 2,337 Year Ended December 31, 2019 2018 (1) Other receivables - allowance for doubtful accounts: Balance, beginning of year $ — $ 838 Additions in allowance charged to expense — — Bad debts charged against allowance — (838 ) Balance, end of year $ — $ — (1) Note 5 . Carrying Value of Long-Lived Assets The Company evaluates its real estate assets for impairment indicators whenever events or changes in circumstances indicate that the carrying value of any of its long-lived assets may not be recoverable. Furthermore, this evaluation is conducted no less frequently than quarterly, irrespective of changes in circumstances. The prolonged outbreak of the COVID-19 pandemic resulted in sustained closure of the Company’s properties for a period of time, as well as the cessation of the operations of certain of its tenants, which has resulted and will likely continue to result in a reduction in the revenues and cash flows of many of its properties due to the adverse financial impacts on its tenants, as well as reductions in other sources of income generated by its properties. In addition to reduced revenues, the Company’s ability to obtain sufficient financing for such properties may be impaired as well as its ability to lease or re-lease properties as a result of worsening market and economic conditions resulting from the COVID-19 pandemic. As of December 31, 2020, the Company’s evaluation of impairment of real estate assets considered its estimate of cash flow declines caused by the COVID-19 pandemic, but its other assumptions, including estimated hold period, were generally unchanged given the highly uncertain environment. The worsening of estimated future cash flows due to a change in the Company’s plans, policies, or views of market and economic conditions as it relates to one or more of its properties adversely impacted by the COVID-19 pandemic could result in the recognition of substantial impairment charges on its assets, which could adversely impact its financial results. For the year ended December 31, 2020, the Company recorded impairment charges of $213,358 related to six of its malls. As of December 31, 2020, seven other properties had impairment indicators; however, based on the Company’s plans with respect to those properties and the economic environment as of December 31, 2020, no additional impairment charges were recorded. Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less as cash equivalents. Restricted Cash Restricted cash of $59,941 and $26,242 was included in intangible lease assets and other assets at December 31, 2020 and 2019, respectively. The $59,941 in restricted cash at December 31, 2020 related to cash held in escrow accounts for insurance, real estate taxes, capital expenditures and tenant allowances as required by the terms of certain mortgage notes payable, as well as amount s related to cash management agreements with the Company’s lenders that are designated for debt service and operating expense obligations . Investments in Unconsolidated Affiliates The Company evaluates its joint venture arrangements to determine whether they should be recorded on a consolidated basis. The percentage of ownership interest in the joint venture, an evaluation of control and whether a VIE exists are all considered in the Company’s consolidation assessment. Initial investments in joint ventures that are in economic substance a capital contribution to the joint venture are recorded in an amount equal to the cash contributed by the Company and the fair value of any real estate contributed. Initial investments in joint ventures that are in economic substance the sale of a portion of the Company’s interest in the real estate are accounted for as a contribution of real estate recorded in an amount equal to the fair value of the ownership interest retained and as a sale of real estate with profit recognized to the extent of the other joint venture partners’ interests in the joint venture. Profit recognition assumes the Company has no commitment to reinvest with respect to the percentage of the real estate sold and the accounting requirements of the full accrual method are met. The Company accounts for its investment in joint ventures where it owns a noncontrolling interest or where it is not the primary beneficiary of a VIE using the equity method of accounting. Under the equity method, the Company’s cost of investment is adjusted for additional contributions to and distributions from the unconsolidated affiliate, as well as its share of equity in the earnings of the unconsolidated affiliate. Generally, distributions of cash flows from operations and capital events are first made to partners to pay cumulative unpaid preferences on unreturned capital balances and then to the partners in accordance with the terms of the joint venture agreements. The Company evaluates its investment in unconsolidated affiliates for impairment indicators whenever events or changes in circumstances indicate that the carrying value of its investment may not be recoverable. The Company’s evaluation of whether an investment in an unconsolidated affiliate has incurred a loss in value that is other than temporary includes an assessment of the expected return generated from the property or properties held within the investment, and the Company’s intent and ability to retain the investment for a period of time to allow for full recovery. Furthermore, this evaluation is conducted no less frequently than quarterly, irrespective of changes in circumstances. The prolonged outbreak of the COVID-19 pandemic resulted in sustained closure of the Company’s properties for a period of time, as well as the cessation of the operations of certain of its tenants, which has resulted and will likely continue to result in a reduction in the revenues and cash flows of many of its properties due to the adverse financial impacts on its tenants, as well as reductions in other sources of income generated by its properties. In addition to reduced revenues, the Company’s ability to obtain sufficient financing for such properties may be impaired as well as its ability to lease or re-lease properties as a result of worsening market and economic conditions resulting from the COVID-19 pandemic. As of December 31, 2020 and 2019, no impairment charges were recorded. In 2018, the Company recorded an impairment of $1,022 as its share of the loss on impairment recognized by an unconsolidated joint venture. The Company recorded a gain on deconsolidation of investments of $67,242 in 2019. See Note 8 Deferred Financing Costs During 2020, as a result of the Chapter 11 Cases, unamortized financing costs of $16,779 related to the Company's secured credit facility and senior unsecured notes were charged to expense and were recorded as “Reorganization items” within the Company’s consolidated statements of operations. Unamortized financing costs related to the secured line of credit of Revenue Recognition See Note 4 for a description of the Company's revenue streams. Gain on Sales of Real Estate Assets Gains on the sale of real estate assets, like all non-lease related revenue, are subject to a five-step model requiring that the Company identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue upon satisfaction of the performance obligations. In circumstances where the Company contracts to sell a property with material post-sale involvement, such involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post-sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized as gain on sale of real estate assets. Property dispositions with no continuing involvement will continue to be recognized upon closing of the sale. Income Taxes The Company is qualified as a REIT under the provisions of the Internal Revenue Code. To maintain qualification as a REIT, the Company is required to distribute at least 90% of its taxable income to shareholders and meet certain other requirements. As a REIT, the Company is generally not liable for federal corporate income taxes. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal and state income taxes on its taxable income at regular corporate tax rates. Even if the Company maintains its qualification as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed income. State tax expense was $2,882, $3,682 and $4,147 during 2020, 2019 and 2018, respectively. The Company has also elected taxable REIT subsidiary status for some of its subsidiaries. This enables the Company to receive income and provide services that would otherwise be impermissible for REITs. For these entities, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if the Company believes all or some portion of the deferred tax asset may not be realized. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in the Company’s judgment about the realizability of the related deferred tax asset is included in income or expense, as applicable. The Company recorded an income tax benefit (provision) as follows for the years ended December 31, 2020, 2019 and 2018: Year Ended December 31, 2020 2019 2018 Current tax provision $ (2,278 ) $ (485 ) $ (1,354 ) Deferred tax benefit (provision) (14,558 ) (2,668 ) 2,905 Income tax benefit (provision) $ (16,836 ) $ (3,153 ) $ 1,551 In 2020, the Company recorded a full deferred tax asset valuation allowance of $16,206, which left a balance of zero as a net deferred tax asset at December 31, 2020. The Company had a net deferred tax asset of $15,117 at December 31, 2019. In 2018, the Company recorded a cumulative effect adjustment in the amount of $11,433 related to the January 1, 2018 adoption of ASU 2016-16. The net deferred tax asset at December 31, 2019 is included in intangible lease assets and other assets. These deferred tax balances primarily consist of differences between book and tax related to the basis of real estate assets, depreciation expense and operating expenses, as well as net operating loss carryforwards. As of December 31, 2020, tax years that generally remain subject to examination by the Company’s major tax jurisdictions include 2020, 2019, 2018 and 2017. The Company reports any income tax penalties attributable to its properties as property operating expenses and any corporate-related income tax penalties as general and administrative expenses in its consolidated statements of operations. In addition, any interest incurred on tax assessments is reported as interest expense. The Company incurred nominal interest and penalty amounts in 2020, 2019 and 2018. Concentration of Credit Risk The Company’s tenants include national, regional and local retailers. Financial instruments that subject the Company to concentrations of credit risk consist primarily of tenant receivables. The Company generally does not obtain collateral or other security to support financial instruments subject to credit risk, but monitors the credit standing of tenants. The Company derives a substantial portion of its rental income from various national and regional retail companies; however, no single tenant collectively accounted for more than 4.5% of the Company’s total consolidated revenues in 2020. Earnings per Share and Earnings per Unit Earnings per Share of the Company Basic earnings per share ("EPS") is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS assumes the issuance of common stock for all potential dilutive common shares outstanding. The limited partners’ rights to convert their noncontrolling interests in the Operating Partnership into shares of common stock are not dilutive. Performance stock units ("PSUs") are contingently issuable common shares and are included in earnings per share if the effect is dilutive. See Note 18 for a description of the long-term incentive program that these units relate to. There were no potential dilutive common shares and no anti-dilutive shares for the year ended December 31, 2020. The effect of 102,820 contingently issuable common shares related to PSUs for the year ended December 31, 2018 were excluded from the computation of diluted EPS because the effect would have been anti-dilutive. Earnings per Unit of the Operating Partnership Basic earnings per unit (“EPU”) is computed using the two-class method. The two-class method is required when either (i) participating securities or (ii) multiple classes of common stock exists. The Operating Partnership’s special common units, and common units issued upon the conversion or redemption of special common units, meet the definition of participating securities as these units have the contractual right and obligation to share in the Operating Partnership’s net income (loss) and distributions. Under this approach net income (loss) attributable to common unitholders is reduced by the amount of distributions made (declared) to all common unitholders and by the amount of distributions that are required to be made (declared and undeclared) to special common unitholders. Distributed and undistributed earnings is subsequently divided by the weighted-average number of common and special common units outstanding for the period to compute basic EPU for each unit. Undistributed losses are allocated 100 percent to common units, other than common units issued upon the conversion or redemption of special common units. The special common units, and common units issued upon the conversion or redemption of special common units, only participate in undistributed losses in the event of a liquidation. Diluted EPU is computed by considering either the two-class method or the if-converted method, whichever results in more dilution. The if-converted method assumes the issuance of common units for all potential dilutive special common units outstanding. Due to the loss position (negative earnings) of the Operating Partnership for the years ended December 31, 2020 and 2019 all special common units, and common units issued upon the conversion or redemption of special common units, are antidilutive. The calculation of diluted EPU through the if-converted method would reduce the loss per share (as a result of an increase number of shares in the denominator) for the common units. Therefore in a loss position diluted EPU is equal to basic EPU. There were no potential dilutive common units and there were no anti-dilutive units other than the special common units, and common units issued upon the conversion or redemption of special common units, outstanding for the years ended December 31, 2020, 2019 and 2018. Use of Estimates The preparation of financial statements in conformity with GAAP requires 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 reported period. Actual results could differ from those estimates.

(4) Marketing revenues solely relate to the Malls segment for all years presented. (5) Sales taxes are excluded from revenues. See Note 13 for information on the Company's segments. Revenue from Contracts with Customers Operating expense reimbursements Under operating and other agreements with third parties, which own anchor or outparcel buildings at the Company's properties and pay no rent, the Company receives reimbursements for certain operating expenses such as ring road and parking area maintenance, landscaping and other fees. These arrangements are primarily either set at a fixed rate with rate increases typically every five years or are on a variable (pro rata) basis, typically as a percentage of costs allocated based on square footage or sales. The majority of these contracts have an initial term and one or more extension options, which cumulatively approximate 50 or more years as historically the initial term and any extension options are typically reasonably certain of being executed by the third party. The standalone selling price of each performance obligation is determined based on the terms of the contract, which typically assigns a price to each performance obligation that directly relates to the value the customer receives for the services being provided. Management, development and leasing fees The Company earns revenue from contracts with third parties and unconsolidated affiliates for property management, leasing, development and other services. These contracts are accounted for on a month-to-month basis if the agreement does not contain substantive penalties for termination. The majority of the Company's contracts with customers are accounted for on a month-to-month basis. The standalone selling price of each performance obligation is determined based on the terms of the contract, which typically assigns a price to each performance obligation that directly relates to the value the customer receives for the services being provided. These contracts generally are for the following: • Management fees - Management fees are charged as a percentage of revenues (as defined in the contract) and recognized as revenue over time as services are provided. • Leasing fees - Leasing fees are charged for newly executed leases and lease renewals and are recognized as revenue upon lease execution, when the performance obligation is completed. In cases for which the agreement specifies 50% of the leasing commission will be paid upon lease execution with the remainder paid when the tenant opens, the Company estimates the amount of variable consideration it expects to receive by evaluating the likelihood of tenant openings using the most likely amount method and records the amount as an unbilled receivable (contract asset). • Development fees - Development fees may be either set as a fixed rate in a separate agreement or be a variable rate based on a percentage of work costs. Variable consideration related to development fees is generally recognized over time using the cost-to-cost method of measurement because it most accurately depicts the Company's performance in satisfying the performance obligation. Contract estimates are based on various assumptions including the cost and availability of materials, anticipated performance and the complexity of the work to be performed. The cumulative catch-up method is used to recognize any adjustments in variable consideration estimates. Under this method, any adjustment is recognized in the period it is identified. Development and leasing fees received from an unconsolidated affiliate are recognized as revenue only to the extent of the third-party partner’s ownership interest. The Company's share of such fees are recorded as a reduction to the Company’s investment in the unconsolidated affiliate. Marketing revenues The Company earns marketing revenues from advertising and sponsorship agreements. These fees may be for tangible items in which the Company provides advertising services and creates signs and other promotional materials for the tenant or may be arrangements in which the customer sponsors a play area or event and receives specified brand recognition and other benefits over a set period of time. Revenue related to advertising services is recognized as goods and services are provided to the customer. Sponsorship revenue is recognized on a straight-line basis over the time period specified in the contract. Performance obligations A performance obligation is a promise in a contract to transfer a distinct good or service to a customer. If the contract does not specify the revenue by performance obligation, the Company allocates the transaction price to each performance obligation based on its relative standalone selling price. Such prices are generally determined using prices charged to customers or using the Company’s expected cost plus margin. Revenue is recognized as the Company’s performance obligations are satisfied over time, as services are provided, or at a point in time, such as leasing a space to earn a commission. Open performance obligations are those in which the Company has not fully or has partially provided the applicable good or services to the customer as specified in the contract. If consideration is received in advance of the Company’s performance, including amounts which are refundable, recognition of revenue is deferred until the performance obligation is satisfied or amounts are no longer refundable. Outstanding Performance Obligations The Company has outstanding performance obligations related to certain noncancellable contracts with customers for which it will receive fixed operating expense reimbursements for providing certain maintenance and other services as described above. As of December 31, 2020, the Company expects to recognize these amounts as revenue over the following periods: Performance obligation Less than 5 years 5-20 years Over 20 years Total Fixed operating expense reimbursements $ 24,400 $ 47,186 $ 41,715 $ 113,301 The Company evaluates its performance obligations each period and makes adjustments to reflect any known additions or cancellations. Performance obligations related to variable consideration, which is based on sales, are constrained.

Leases [Abstract]
Leases	NOTE 5. LEASES Lessor Rental Revenues The majority of the Company’s revenues are earned through the lease of space at its properties. All of the Company's leases with tenants for the use of space at its properties are classified as operating leases. Rental revenues include minimum rent, percentage rent, other rents and reimbursements from tenants for real estate taxes, insurance, common area maintenance ("CAM") and other operating expenses as provided in the lease agreements. The option to extend or terminate the Company’s leases is specific to each underlying tenant lease agreement. Typically, the Company's leases contain penalties for early termination. The Company doesn't have any leases that convey the right for the lessee to purchase the leased asset. Minimum rental revenue from operating leases is recognized on a straight-line basis over the initial terms of the related leases. Certain tenants are required to pay percentage rent if their sales volumes exceed thresholds specified in their lease agreements. Percentage rent is recognized as revenue when the thresholds are achieved and the amounts become determinable. The Company receives reimbursements from tenants for real estate taxes, insurance, CAM and other recoverable operating expenses as provided in the lease agreements. Any tenant reimbursements that require fixed payments are recognized on a straight-line basis over the initial terms of the related leases, whereas any variable payments are recognized when earned in accordance with the tenant lease agreements. Tenant reimbursements related to certain capital expenditures are billed to tenants over periods of 5 to 15 years. The components of rental revenues are as follows: Year Ended December 31, 2020 2019 2018 Fixed lease payments $ 459,958 $ 607,259 $ 684,634 Variable lease payments 94,106 129,619 144,479 Total rental revenues $ 554,064 $ 736,878 $ 829,113 The undiscounted future fixed lease payments to be received under the Company's operating leases as of December 31, 2020, are as follows: Years Ending December 31, Operating Leases 2021 $ 401,573 2022 344,777 2023 288,775 2024 232,399 2025 175,956 Thereafter 412,502 Total undiscounted lease payments $ 1,855,982 Lessee The Company has eight ground leases and one office lease in which it is a lessee. The maturities of these leases range from 2021 to 2089 and generally provide for renewal options ranging from five to ten years. The Company included the renewal options in its lease terms for purposes of calculating its lease liability and ROU asset because it has no plans to cease operating its assets associated with each ground lease. The ground leases relate to properties where the Company owns the buildings and improvements but leases the underlying land. The lease payments on the majority of the ground leases are fixed, but in the instances where they are variable, they are either based on the CPI index or a percentage of sales. The office lease is subleased as of December 31, 2020. As of December 31, 2020, these leases have a weighted-average remaining lease term of 42.8 years and a weighted-average discount rate of 8.3%. The Company's ROU asset and lease liability are presented in the consolidated balance sheets within intangible lease assets and other assets and accounts payable and accrued liabilities, respectively. A summary of the Company's ROU asset and lease liability activity during the year ended December 31, 2020 and 2019 is presented below: ROU Asset Lease Liability Balance as of January 1, 2019 $ 4,160 $ 4,074 Cash reduction (557 ) (557 ) Noncash decrease 201 320 Balance as of January 1, 2020 3,804 3,837 Cash reduction (373 ) (373 ) Noncash decrease (128 ) (134 ) Balance as of December 31, 2020 $ 3,303 $ 3,330 The components of lease expense are presented below: Year Ended December 31, 2020 Year Ended December 31, 2019 Lease expense: Operating lease expense $ 462 $ 547 Variable lease expense 223 348 Total lease expense $ 685 $ 895 The undiscounted future lease payments to be paid under the Company's operating leases as of December 31, 2020, are as follows: Year Ending December 31, Operating Leases 2021 $ 379 2022 299 2023 284 2024 264 2025 269 Thereafter 11,747 Total undiscounted lease payments 13,242 Less imputed interest (9,912 ) Lease liability $ 3,330

Equity Method Investments And Joint Ventures [Abstract]
UNCONSOLIDATED AFFILIATES	NOTE 8. UNCONSOLIDATED AFFILIATES Unconsolidated Affiliates Although the Company had majority ownership of certain joint ventures during 2020, 2019 and 2018, it evaluated the investments and concluded that the other partners or owners in these joint ventures had substantive participating rights, such as approvals of: • the pro forma for the development and construction of the project and any material deviations or modifications thereto; • the site plan and any material deviations or modifications thereto; • the conceptual design of the project and the initial plans and specifications for the project and any material deviations or modifications thereto; • any acquisition/construction loans or any permanent financings/refinancings; • the annual operating budgets and any material deviations or modifications thereto; • the initial leasing plan and leasing parameters and any material deviations or modifications thereto; and • any material acquisitions or dispositions with respect to the project. As a result of the joint control over these joint ventures, the Company accounts for these investments using the equity method of accounting.

See Note 20 for additional information. ( 2 ) Issued by the Operating Partnership. CBL is a limited guarantor of the Operating Partnership's obligations under the Notes as described above. The Company elected to not make the $6,900 interest payment (the “2024 Notes Interest Payment”) due and payable on October 15, 2020, with respect to the 2024 Notes. Under the indenture governing the 2024 Notes, the Operating Partnership had a 30-day grace period to make the 2024 Notes Interest Payment before the nonpayment was considered an “event of default” with respect to the 2024 Notes. The Company filed the Chapter 11 Cases prior to the end of the 30-day grace period. Senior Secured Credit Facility The Company has a $1,185,000 senior secured credit facility, which includes a revolving line of credit drawn to its maximum borrowing capacity of $675,926 and a term loan with an outstanding balance of $438,750 at December 31, 2020. The facility matures in July 2023 Note 2 and in Financial Covenants and Restrictions below, the filing of the Chapter 11 Cases constituted an event of default that resulted in certain monetary obligations becoming immediately due and payable with respect to the secured credit facility. The Operating Partnership is required to pay an annual facility fee, to be paid quarterly, which ranges from 0.25% to 0.35%, based on the unused capacity of the line of credit. The terms of the facility also require the principal balance on the term loan to be reduced by $35,000 per year in quarterly installments. In March 2020, the Company drew $280,000 on its secured credit facility to increase liquidity and preserve financial flexibility in light of the uncertainty surrounding the impact of the COVID-19 pandemic. At December 31, 2020, the secured line of credit had an outstanding balance of $675,926. As a result of the event of default due to the filing of the Chapter 11 Cases described under Financial Covenants and Restrictions below, the Operating Partnership cannot borrow any additional amounts under the secured line of credit. The secured credit facility is secured by 17 malls and 3 associated centers that are owned by 36 wholly owned subsidiaries of the Operating Partnership (collectively the “Combined Guarantor Subsidiaries”). The Combined Guarantor Subsidiaries own an additional four malls, two associated centers and four mortgage notes receivable that are not collateral for the secured credit facility. The properties that are collateral for the secured credit facility and the properties and mortgage notes receivable that are not collateral are collectively referred to as the “Guarantor Properties.” The terms of the Notes provide that, to the extent that any subsidiary of the Operating Partnership executes and delivers a guarantee to another debt facility, the Operating Partnership shall also cause the subsidiary to guarantee the Operating Partnership’s obligations under the Notes on a senior basis. In January 2019, the Combined Guarantor Subsidiaries entered into a guarantee agreement with the issuer of the Notes to satisfy the guaranty requirement. See Financial Covenants and Restrictions below and Liquidity and Going Concern Considerations and Voluntary Reorganization under Chapter 11 in Note 2 for information on the event of default resulting from the filing of the Chapter 11 Cases. Financial Covenants and Restrictions The agreements for the Notes and senior secured credit facility contain default provisions customary for transactions of this nature (with applicable customary grace periods). Additionally, any default in the payment of any recourse indebtedness greater than or equal to $50,000 of the Operating Partnership will constitute an event of default under the Notes and the senior secured credit facility. Additionally, the senior secured credit facility contains a provision that any default on a payment of non-recourse indebtedness in excess of $150,000 is also a default of the senior secured credit facility. The filing of the Chapter 11 Cases constituted an event of default that resulted in certain monetary obligations becoming immediately due and payable with respect to the secured credit facility and the senior unsecured notes. The filing of the Chapter 11 Cases also constituted an event of default with respect to certain property-level debt of the Operating Partnership’s subsidiaries, which may result in acceleration of the outstanding principal and other sums due. Certain of the Company’s properties that are pledged as collateral on non-recourse mortgage loans and the secured credit facility are subject to cash management agreements with the lenders, which restrict the cash balances associated with those properties to only be used for debt service and operating expense obligations. Fixed-Rate Debt As of December 31, 2020, fixed-rate loans on operating Properties bear interest at stated rates ranging from 4.36% to 5.99%. Fixed-rate loans on operating Properties generally provide for monthly payments of principal and/or interest and mature at various dates through June 2026, with a weighted-average maturity of 1.6 years. 2020 Modifications The maturity date for the fixed-rate loan secured by Jefferson Mall was extended from June 1, 2022 to June 1, 2026. The loan will be interest only through March 2021 when monthly payments of principal and interest will be made through the maturity date. 2019 Financings In April 2019, the loan secured by Volusia Mall was refinanced to increase the principal balance to $50,000. In addition, the maturity date was extended to May 2024 and the fixed interest rate was reduced from 8.00% to 4.56%. The net proceeds from the new loan were used to retire the $41,000 existing loan and a portion of the loan secured by Honey Creek Mall, as described below. In May 2019, the Company exercised an option to extend the loan secured by The Outlet Shoppes at Laredo to May 2021. In conjunction with the amendment, a payment of $10,800 was made to reduce the outstanding balance of the loan to $43,000. The noncontrolling interest partner in the joint venture funded its 35% share of the $10,800 payment. Loan Repayments The Company repaid the following fixed-rate loans, secured by the related consolidated Properties, in 2020 and 2019: Date Property Interest Rate at Repayment Date Scheduled Maturity Date Principal Balance Repaid (1) 2020: February Parkway Place 6.50% July 2020 $ 33,186 February Valley View Mall 6.50% July 2020 51,360 $ 84,546 2019: April Honey Creek Mall (2) 8.00% July 2019 $ 23,539 December The Terrace 7.25% June 2020 11,931 $ 35,470 (1) The Company retired the loans with borrowings from its credit facilities unless otherwise noted. (2) The Company retired the loan using proceeds from the refinancing of the loan secured by Volusia Mall as well as proceeds from the sale of Honey Creek Mall. Dispositions The following is a summary of the Company's dispositions for which the fixed-rate loan secured by the mall was extinguished: Sale/Transfer Date Property Interest Rate at Repayment Date Scheduled Maturity Date Balance of Non-recourse Debt Gain on Extinguishment of Debt 2020: August Hickory Point Mall (1) 5.85% December 2019 $ 27,446 $ 15,446 December Burnsville Mall (1) 6.00% July 2020 64,233 17,075 $ 91,679 $ 32,521 2019: January Acadiana Mall (1) 5.67% April 2017 $ 119,760 $ 61,795 January Cary Towne Center (2) 4.00% June 2018 43,716 9,927 $ 163,476 $ 71,722 (1) The Company transferred title to the mall to the mortgage holder in satisfaction of the non-recourse debt secured by the Property. (2) The Company sold the mall for $31,500 and the net proceeds from the sale were used to satisfy a portion of the loan secured by the mall. The remaining principal balance was forgiven. Variable-Rate Debt The recourse loans secured by operating properties bear interest at a variable interest rate indexed to LIBOR. At December 31, 2020, the interest rates ranged from 3.05% to 5.80%. These loans mature in 2021. Financing The Company entered into a construction loan in October 2018 to redevelop anchor space at Brookfield Square. The loan bears interest at a variable interest rate indexed to LIBOR. At December 31, 2020, the interest rate was 3.1%. This loan matures in October 2021 and has one 12-month extension option for an outside maturity date of October 2022. The Company is in discussions with the lender regarding the extension option because the filing of the Chapter 11 Cases constituted an event of default under the loan agreement. The loan was reclassified as an operating property loan during 2020 due to construction and all loan draws being completed. Loans in Default As of December 31, 2020, four non-recourse loans that are each secured by one of the Company’s malls were in default. The default of the four non-recourse loans occurred prior to the filing of the Chapter 11 Cases. As of December 31, 2020, the lenders under each of these loans accelerated the outstanding amount due and payable on the loans. Subsequent to December 31, 2020, Asheville Mall and Park Plaza were turned over to receivers to manage the properties (see Note 20 ). The foreclosure process has not yet commenced in relation to EastGate Mall. The Company is in discussions with the lender regarding a restructure of the loan secured by Greenbrier Mall. Property Location Interest Rate Scheduled Maturity Date Loan Amount Greenbrier Mall Chesapeake, VA 5.41% Dec-19 $ 61,647 EastGate Mall Cincinnati, OH 5.83% Apr-21 31,181 Park Plaza Little Rock, AR 5.28% Apr-21 76,805 Asheville Mall Asheville, NC 5.80% Sep-21 62,121 As described in Note 2 , the filing of the Chapter 11 Cases also constituted an event of default with respect to certain property-level debt of the Operating Partnership’s subsidiaries, which may have resulted in the automatic acceleration of certain monetary obligations or may give the applicable lender the right to accelerate such amounts. There are 14 of such loans that have an aggregate outstanding balance of $833,444 at December 31, 2020. Other Several of the Company’s Properties are owned by special purpose entities, created as a requirement under certain loan agreements that are included in the Company’s consolidated financial statements. The sole business purpose of the special purpose entities is to own and operate these Properties.

Equity [Abstract]
SHAREHOLDERS' EQUITY AND PARTNERS' CAPITAL	NOTE 10. SHAREHOLDERS’ EQUITY AND PARTNERS' CAPITAL Common Stock and Common Units The Company's authorized common stock consists of 350,000,000 shares at $0.01 par value per share. The Company had 196,569,917 and 174,115,111 shares of common stock issued and outstanding as of December 31, 2020 and 2019, respectively. Partners in the Operating Partnership hold their ownership through common and special common units of limited partnership interest, hereinafter referred to as "common units." A common unit and a share of CBL's common stock have essentially the same economic characteristics, as they effectively participate equally in the net income and distributions of the Operating Partnership, except for certain special common units as disclosed in Note 11 . For each share of common stock issued by CBL, the Operating Partnership has issued a corresponding number of common units to CBL in exchange for the proceeds from the stock issuance. The Operating Partnership had 201,687,773 and 200,189,077 common units outstanding as of December 31, 2020 and 2019, respectively. Each limited partner in the Operating Partnership has the right to exchange all or a portion of its common units for shares of CBL's common stock, or at the Company's election, their cash equivalent. When an exchange for common stock occurs, the Company assumes the limited partner's common units in the Operating Partnership. The number of shares of common stock received by a limited partner of the Operating Partnership upon exercise of its exchange rights will be equal, on a one-for-one basis, to the number of common units exchanged by the limited partner. If the Company elects to pay cash, the amount of cash paid by the Operating Partnership to redeem the limited partner's common units will be based on the five-day trailing average of the trading price, at the time of exchange, of the shares of common stock that would otherwise have been received by the limited partner in the exchange. However, for so long as the current distribution suspension results in the existence of a distribution shortfall (as described in the Partnership Agreement of the Operating Partnership) with respect to any of the S-SCUs, the L-SCUs or the K-SCUs (an “SCU Distribution Shortfall”), the Company may not elect to settle any exchange requested by a holder of common units of the Operating Partnership in cash, and may only settle any such exchange through the issuance of shares of common stock or other units of the Operating Partnership ranking junior to any such units as to which a distribution shortfall exists. The Company’s Board of Directors has prospectively approved that to the extent any partners exercise any or all of their exchange rights while the existence of the SCU Distribution Shortfall requires any exchange to be settled through the issuance of shares of common stock or other units of the Operating Partnership, the consideration paid shall be in the form of shares of common stock. Neither the common units nor the shares of CBL's common stock are subject to any right of mandatory redemption. Pursuant to the terms of the Series L special common units of limited partnership interest, the Series L special common units began receiving distributions equal to those on the common units beginning on June 1, 2020. Earnings per Unit of the Operating Partnership The following table presents basic and diluted EPU for common and special common units for the years ended December 31, 2020, 2019 and 2018 (in thousands, except per unit data): Year Ended December 31, 2020 2019 2018 Net Loss Attributable to Common Unitholders $ (352,256 ) $ (177,352 ) $ (143,148 ) Distributions to Common Unitholders - Declared Only — (14,638 ) (131,256 ) Distributions to Special Common Unitholders - Declared and Undeclared Common units issued on conversion of SCUs — (133 ) (1,249 ) S-SCUs (3,810 ) (4,572 ) (4,572 ) L-SCUs (433 ) (1,732 ) (1,732 ) K-SCUs (2,746 ) (3,375 ) (3,393 ) Total Undistributed Losses Available to Common and Special Common Unitholders $ (359,245 ) $ (201,802 ) $ (285,350 ) Distributed Earnings: Common units issued on conversion of SCUs $ — $ 133 $ 1,249 S-SCUs 3,810 4,572 4,572 L-SCUs 433 1,732 1,732 K-SCUs 2,746 3,375 3,393 Common Units — 14,639 131,257 Undistributed Losses: Common units issued on conversion of SCUs $ — $ — $ — S-SCUs — — — L-SCUs — — — K-SCUs — — — Common Units (359,245 ) (201,802 ) (285,350 ) Weighted Average: Common units issued on conversion of SCUs 1,534 1,758 1,872 S-SCUs 1,561 1,561 1,561 L-SCUs 572 572 572 K-SCUs 1,069 1,137 1,144 Common Units 196,850 195,142 194,430 Basic EPU: Common units issued on conversion of SCUs $ — $ 0.08 $ 0.67 S-SCUs 2.44 2.93 2.93 L-SCUs 0.76 3.03 3.03 K-SCUs 2.57 2.97 2.96 Common Units (1.82 ) (0.96 ) (0.79 ) Total Basic EPU $ (1.75 ) $ (0.89 ) $ (0.72 ) Diluted EPU: Common units issued on conversion of SCUs $ — $ 0.08 $ 0.67 S-SCUs 2.44 2.93 2.93 L-SCUs 0.76 3.03 3.03 K-SCUs 2.57 2.97 2.96 Common Units (1.82 ) (0.96 ) (0.79 ) Total Diluted EPU $ (1.75 ) $ (0.89 ) $ (0.72 ) At-The-Market Equity Program On March 1, 2013, the Company entered into the Sales Agreements (collectively, the "Sales Agreements") with a number of sales agents to sell shares of CBL's common stock, having an aggregate offering price of up to $300,000, from time to time in the ATM equity offerings (as defined in Rule 415 of the Securities Act of 1933, as amended) or in negotiated transaction (the "ATM program"). In accordance with the Sales Agreements, the Company will set the parameters for the sales of shares, including the number of shares to be issued, the time period during which sales are to be made and any minimum price below which sales may not be made. The Sales Agreements provide that the sales agents will be entitled to compensation for their services at a mutually agreed commission rate not to exceed 2.0% of the gross proceeds from the sales of shares sold through the ATM program. For each share of common stock issued by CBL, the Operating Partnership issues a corresponding number of common units of limited partnership interest to CBL in exchange for the contribution of the proceeds from the stock issuance. The Company includes only share issuances that have settled in the calculation of shares outstanding at the end of each period. Since inception, the Company has sold $211,493 of common stock through the ATM program, at a weighted-average sales price of $25.12, generating net proceeds of $209,596, which were used to reduce the balances on the Company's credit facilities. Since the commencement of the ATM program, the Company has issued 8,419,298 shares of common stock and approximately $88,507 remains available that may be sold under this program as of December 31, 2020. The Company has not sold any shares under the ATM program since 2013. Actual future sales under this program, if any, will depend on a variety of factors including but not limited to market conditions, the trading price of CBL's common stock and the Company's capital needs. The Company has no obligation to sell the remaining shares available under the ATM program and currently is unable to use its shelf registration statement covering the sale of such shares. Common Unit Activity During 2020, the Company issued 20,956,110 shares of common stock to 31 holders of 20,956,110 common units and special common units of limited partnership interest in the Operating Partnership in connection with the exercise of the holders’ contractual exchange rights. During 2019, the Operating Partnership elected to pay cash of $96 to a During 2018, the Operating Partnership elected to pay cash of $2,246 to two holders of 526,510 common units in the Operating Partnership upon the exercise of their conversion rights. The Company also issued 915,338 shares of common stock to a Preferred Stock and Preferred Units The Company's authorized preferred stock consists of 15,000,000 shares at $0.01 par value per share. A description of the Company's cumulative redeemable preferred stock is listed below. The Operating Partnership issues an equivalent number of preferred units to CBL in exchange for the contribution of the proceeds from CBL to the Operating Partnership when CBL issues preferred stock. The preferred units generally have the same terms and economic characteristics as the corresponding series of preferred stock. The Company has 6,900,000 depositary shares, each representing 1/10th of a share of CBL's 6.625% Series E Preferred Stock with a par value of $0.01 per share, outstanding as of December 31, 2020 and 2019. The Series E Preferred Stock has a liquidation preference of $250.00 per share ($25.00 per depositary share). The dividends on the Series E Preferred Stock are cumulative, accrue from the date of issuance and are payable quarterly in arrears at a rate of $16.5625 per share ($1.65625 per depositary share) per annum. The Series E Preferred Stock generally has no stated maturity, is not subject to any sinking fund or mandatory redemption, and is not convertible into any other securities of the Company, except under certain circumstances in connection with a change of control. Owners of the depositary shares representing Series E Preferred Stock generally have no voting rights except under dividend default. The Company may redeem shares, in whole or in part, at any time for a cash redemption price of $250.00 per share ($25.00 per depositary share) plus accrued and unpaid dividends. The Company has 18,150,000 depositary shares, each representing 1/10th of a share of CBL's 7.375% Series D Preferred Stock with a par value of $0.01 per share, outstanding as of December 31, 2020 and 2019. The Series D Preferred Stock has a liquidation preference of $250.00 per share ($25.00 per depositary share). The dividends on the Series D Preferred Stock are cumulative, accrue from the date of issuance and are payable quarterly in arrears at a rate of $ 18.4375 per share ($ 1.84375 per depositary share) per annum. The Series D Preferred Stock has no stated maturity, is not subject to any sinking fund or mandatory redemption and is not convertible into any other securities of the Company. The Company may redeem shares, in whole or in part, at any time for a cash redemption price of $ 250.00 per share ($25.00 per depositary share) plus accrued and unpaid dividends. In December 2019, the Company announced the suspension of all future dividends on its 7.375% Series D Cumulative Redeemable Preferred Stock and 6.625% Series E Cumulative Redeemable Preferred Stock. Unpaid dividends on the Company’s preferred stock accrued without interest prior to the filing of the Chapter 11 Cases, after which the accrual ceased, and amounted to $37,410 and $11,223 at December 31, 2020 and 2019, respectively. The Company will review taxable income on a regular basis and take measures, if necessary, to ensure that it meets the minimum distribution requirements to maintain its status as a REIT. Dividends - CBL CBL paid a first quarter 2019 cash dividend on its common stock of $0.075 per share on April 16, 2019. Under the terms of a litigation settlement agreement, the Company did not pay any dividends to holders of its common shares payable in the third and fourth quarters of 2019 (see Note 16 for more information on the litigation settlement agreement). As noted above, in December 2019 the Company suspended all future dividends on its common stock and preferred stock, as well as distributions to all noncontrolling interest investors in its Operating Partnership (as noted below). No dividends may be paid on shares of the Company’s common stock unless (i) all accrued but unpaid dividends on its preferred stock, and any current dividend then due, have been paid in cash, or a cash sum sufficient for such payment has been set apart for payment and (ii) the SCU Distribution Shortfall created by its related suspension of distributions to noncontrolling interest investors in its Operating Partnership has likewise been remedied through the payment of distributions sufficient to satisfy such shortfall for all prior periods and the then-current period (thereby allowing the resumption of distributions on the common units in the Operating Partnership that are held by the Company, which fund its common stock dividends). The decision to declare and pay dividends on the Company’s common stock in the future, as well as the timing, amount and composition of any such future dividends, will be at the sole discretion of its board of directors. For purposes of determining net income (loss) attributable to common shareholders, the Company disclosed the cumulation of undeclared dividends on its Series D Preferred Stock and Series E Preferred Stock. The undeclared dividends on the Company’s Series D Preferred Stock and Series E Preferred Stock ceased to cumulate as of the Commencement Date as a result of the Chapter 11 Cases. For purposes of determining net income (loss) attributable to common unitholders, the Company disclosed the cumulation of undeclared distributions on its preferred units and special common units. The undeclared distributions on the preferred units and special common units ceased to cumulate as of the Commencement Date as a result of the Chapter 11 Cases. The allocations of dividends declared and paid for income tax purposes are as follows (income tax allocations are not applicable in 2020 due to the Company not paying any dividends in 2020): Year Ended December 31, 2019 2018 Dividends declared: Common stock $ 0.15 $ 0.80 (1) Series D preferred stock $ 13.83 $ 18.44 Series E preferred stock $ 12.42 $ 16.56 Allocations: Common stock Ordinary income — % 82.83 % Capital gains 25% rate — % — % Return of capital 100.00 % 17.17 % Total 100.00 % 100.00 % Preferred stock (2) Ordinary income — % 100.00 % Capital gains 25% rate — % — % Return of capital 100.00 % — % Total 100.00 % 100.00 % (1) Of the $0.075 per share dividend declared on October 29, 2018 and paid January 16, 2019, $0.075 was reported and is taxable in 2019. ( 2 ) The allocations for income tax purposes are the same for each series of preferred stock for each period presented. Distributions - The Operating Partnership The Operating Partnership paid first, second and third quarter 2019 cash distributions on its redeemable common units of $0.7322 per share on April 16, July 16 and October 16, 2019.

Redeemable Noncontrolling Interests And Noncontrolling Interests [Abstract]
REDEEMABLE INTERESTS AND NONCONTROLLING INTERESTS	NOTE 11. REDEEMABLE INTERESTS AND NONCONTROLLING INTERESTS Redeemable Noncontrolling Interests and Noncontrolling Interests of the Company Partnership Interests in the Operating Partnership that Are Not Owned by the Company The common units that the Company does not own are reflected in the Company's consolidated balance sheets as redeemable noncontrolling interest and noncontrolling interests in the Operating Partnership. Series S Special Common Units Redeemable noncontrolling interest includes a noncontrolling partnership interest in the Operating Partnership for which the partnership agreement includes redemption provisions that may require the Operating Partnership to redeem the partnership interest for real property. In July 2004, the Operating Partnership issued 1,560,940 Series S special common units (“S-SCUs”), all of which are outstanding as of December 31, 2020, in connection with the acquisition of Monroeville Mall. Under the terms of the Operating Partnership’s limited partnership agreement, the holder of the S-SCUs has the right to exchange all or a portion of its partnership interest for shares of the Company’s common stock or, at the Company’s election, their cash equivalent. The holder has the additional right to require the Operating Partnership to acquire a qualifying property and distribute it to the holder in exchange for the S-SCUs. Generally, the acquisition price of the qualifying property cannot be more than the lesser of the consideration that would be received in a normal exchange, as discussed above, or $20,000, subject to certain limited exceptions. Should the consideration that would be received in a normal exchange exceed the maximum property acquisition price as described in the preceding sentence, the excess portion of its partnership interest could be exchanged for shares of CBL's stock or, at the Company’s election, their cash equivalent. The S-SCUs receive a minimum distribution of $2.92875 per unit per year which will cumulate (similar to a preferred dividend) during the current SCU Distribution Shortfall, with the SCU Distribution Shortfall being required to be fully cured (on a ratable basis among the respective holders of S-SCUs, L-SCUs and K-SCUs) before any distributions may be resumed with respect to regular common units, pursuant to the terms of the Operating Partnership’s limited partnership agreement. Series L Special Common Units In June 2005, the Operating Partnership issued 571,700 Series L special common units ("L-SCUs"), all of which are outstanding as of December 31, 2020, in connection with the acquisition of Laurel Park Place. The L-SCUs receive a minimum distribution of $0.7572 per unit per quarter ($3.0288 per unit per year) which will cumulate (similar to a preferred dividend) during the current SCU Distribution Shortfall, with the SCU Distribution Shortfall being required to be fully cured (on a ratable basis among the respective holders of S-SCUs, L-SCUs and K-SCUs) before any distributions may be resumed with respect to regular common units, pursuant to the terms of the Operating Partnership’s limited partnership agreement. Upon the earlier to occur of June 1, 2020, or when the distribution on the common units exceeds $0.7572 per unit for four consecutive calendar quarters, the L-SCUs will thereafter receive a distribution equal to the amount paid on the common units. In December 2012, the Operating Partnership issued 622,278 common units valued at $14,000 to acquire the remaining 30% noncontrolling interest in Laurel Park Place. Pursuant to the terms of the Series L special common units of limited partnership interest, the Series L special common units began receiving distributions equal to those on the common units beginning on June 1, 2020. Series K Special Common Units In November 2005, the Operating Partnership issued 1,144,924 Series K special common units ("K-SCUs") in connection with the acquisition of Oak Park Mall, Eastland Mall and Hickory Point Mall. The holders of the K-SCUs receive a dividend at a rate of 6.25%, or $2.96875 per K-SCU, which will cumulate (similar to a preferred dividend) during the current SCU Distribution Shortfall, with the SCU Distribution Shortfall being required to be fully cured (on a ratable basis among the respective holders of S-SCUs, L-SCUs and K-SCUs) before any distributions may be resumed with respect to regular common units, pursuant to the terms of the Operating Partnership’s limited partnership agreement . When the quarterly distribution on the Operating Partnership’s common units exceeds the quarterly K-SCU distribution for four consecutive quarters, the K-SCUs will receive distributions at the rate equal to that paid on the Operating Partnership’s common units. The holders of the K-SCUs may exchange them, on a one -for-one basis, for shares of CBL’s common stock or, at the Company’s election, their cash equivalent . In December 2018, the Operating Partnership elected to pay $21 in cash to a holder of 8,120 K-SCUs upon the exercise of the holder’s conversion rights. In September 2020, the Company issued 267,983 shares of common stock to a Outstanding rights to convert redeemable noncontrolling interests and noncontrolling interests in the Operating Partnership to common stock were held by the following parties at December 31, 2020 and 2019: December 31, 2020 2019 CBL’s Predecessor — 18,117,350 Third parties 5,117,856 7,956,616 5,117,856 26,073,966 The assets and liabilities allocated to the Operating Partnership’s redeemable noncontrolling interest and noncontrolling interests are based on their ownership percentages of the Operating Partnership at December 31, 2020 and 2019. The ownership percentages are determined by dividing the number of common units held by each of the redeemable noncontrolling interest and the noncontrolling interests at December 31, 2020 and 2019 by the total common units outstanding at December 31, 2020 and 2019, respectively. The redeemable noncontrolling interest ownership percentage in assets and liabilities of the Operating Partnership was 0.8% at December 31, 2020 and 2019. The noncontrolling interest ownership percentage in assets and liabilities of the Operating Partnership was 1.8% and 12.2% at December 31, 2020 and 2019, respectively. Income is allocated to the Operating Partnership’s redeemable noncontrolling interest and noncontrolling interests based on their weighted-average ownership during the year. The ownership percentages are determined by dividing the weighted-average number of common units held by each of the redeemable noncontrolling interest and noncontrolling interests by the total weighted-average number of common units outstanding during the year. A change in the number of shares of common stock or common units changes the percentage ownership of all partners of the Operating Partnership. A common unit is considered to be equivalent to a share of common stock since it generally is exchangeable for shares of the Company’s common stock or, at the Company’s election, their cash equivalent. As a result, an allocation is made between redeemable noncontrolling interests, shareholders’ equity and noncontrolling interests in the Operating Partnership in the Company's accompanying balance sheets to reflect the change in ownership of the Operating Partnership’s underlying equity when there is a change in the number of shares and/or common units outstanding. During 2020, 2019 and 2018, the Company allocated $302, $3,398 and $4,065, respectively, from shareholders’ equity to redeemable noncontrolling interest. During 2020, 2019 and 2018, the Company allocated $6,002, $4,392 and $13,642, respectively, from shareholders' equity to noncontrolling interest. The total redeemable noncontrolling interest in the Operating Partnership was $(265) and $2,160 at December 31, 2020 and 2019, respectively. The total noncontrolling interest in the Operating Partnership was $(604) and $31,592 at December 31, 2020 and 2019, respectively. Redeemable Noncontrolling Interests and Noncontrolling Interests in Other Consolidated Subsidiaries The Company had 12 other consolidated subsidiaries at December 31, 2020 and 2019 that had noncontrolling interests held by third parties and for which the related partnership agreements either do not include redemption provisions or are subject to redemption provisions that do not require classification outside of permanent equity. The total noncontrolling interests in other consolidated subsidiaries were $3,058 and $23,961 at December 31, 2020 and 2019, respectively. The assets and liabilities allocated to the redeemable noncontrolling interests and noncontrolling interests in other consolidated subsidiaries are based on the third parties’ ownership percentages in each subsidiary at December 31, 2020 and 2019. Income is allocated to the redeemable noncontrolling interests and noncontrolling interests in other consolidated subsidiaries based on the third parties’ weighted-average ownership in each subsidiary during the year. Redeemable Interests and Noncontrolling Interests of the Operating Partnership The S-SCUs described above that are reflected as redeemable noncontrolling interests in the Company's consolidated balance sheets are reflected as redeemable common units in the Operating Partnership's consolidated balance sheets. The noncontrolling interests in other consolidated subsidiaries that are held by third parties that are reflected as a component of noncontrolling interests in the Company's consolidated balance sheets comprise the entire amount that is reflected as noncontrolling interests in the Operating Partnership's consolidated balance sheets. Variable Interest Entities In accordance with the guidance in ASU 2015-02, Amendments to the Consolidation Analysis Interests Held Through Related Parties That Are under Common Control The Company consolidates the Operating Partnership, which is a VIE, for which the Company is the primary beneficiary. The Company, through the Operating Partnership, consolidates all VIEs for which it is the primary beneficiary. Generally, a VIE is a legal entity in which the equity investors do not have the characteristics of a controlling financial interest or the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support. A limited partnership is considered a VIE when the majority of the limited partners unrelated to the general partner possess neither the right to remove the general partner without cause, nor certain rights to participate in the decisions that most significantly affect the financial results of the partnership. In determining whether the Company is the primary beneficiary of a VIE, the Company considers qualitative and quantitative factors, including, but not limited to: which activities most significantly impact the VIE’s economic performance and which party controls such activities; the amount and characteristics of the Company's investment; the obligation or likelihood for the Company or other investors to provide financial support; and the similarity with and significance to the Company's business activities and the business activities of the other investors. The table below lists the Company's consolidated VIEs as of December 31, 2020 and 2019, which do not reflect the elimination of any internal debt the consolidated VIE has with the Operating Partnership: As of December 31, 2020 2019 Assets Liabilities (1) Assets Liabilities (1) Consolidated VIEs: Atlanta Outlet Outparcels, LLC $ 851 $ — $ 862 $ — CBL Terrace LP 14,608 12,578 15,012 12,595 Gettysburg Outlet Center Holding, LLC 33,199 38,334 34,399 38,268 Gettysburg Outlet Center, LLC 7,737 — 7,690 (69 ) High Point Development LP II — — (22 ) — Jarnigan Road LP 17,974 572 18,631 641 Jarnigan Road II, LLC 22,623 17,134 23,424 17,704 Laredo Outlet JV, LLC 44,378 43,788 103,375 45,360 Lebcon Associates 46,692 116,085 80,081 121,493 Lebcon I, Ltd 8,305 8,672 8,386 8,906 Louisville Outlet Outparcels, LLC 173 — 174 — Madison Grandview Forum, LLC — — 338 83 The Promenade at D'Iberville 75,975 48,964 78,066 48,270 Statesboro Crossing, LLC 227 — 213 (10 ) $ 272,742 $ 286,127 $ 370,629 $ 293,241 ( 1 ) Includes $40,600 and $41,950 related to Laredo Outlet JV, LLC, which is guaranteed by the Operating Partnership, as of December 31, 2020 and 2019, respectively.

Accounts Notes Loans And Financing Receivable Gross Allowance And Net [Abstract]
MORTGAGE AND OTHER NOTES RECEIVABLE	NOTE 12. MORTGAGE AND OTHER NOTES RECEIVABLE The Company's mortgage note receivable is collateralized by an assignment of 100% of the partnership interests that own the real estate assets. Other notes receivable include amounts due from tenants and unsecured notes received from third parties as whole or partial consideration for property or investments. Mortgage and other notes receivable consist of the following: As of December 31, 2020 As of December 31, 2019 Maturity Date Interest Rate Balance Interest Rate Balance Mortgage Dec 2016 (1) 2.64% $ 1,100 4.28% - 9.50% $ 2,637 Other Notes Receivable Sep 2021- Apr 2026 4.00% - 5.00% 1,237 4.00% - 5.00% 2,025 $ 2,337 $ 4,662 ( 1 ) Represents a $1,100 note with D'Iberville Promenade, LLC with a maturity date of December 2016, that is in default. This is secured by the joint venture partner’s interest in the joint venture. Expected credit losses As of December 31, 2020, the one mortgage note receivable is in default, but as noted above, the Company has a noncontrolling interest recorded related to the defaulting partner’s interest that serves as collateral on the note, and that amount is greater than the outstanding balance on the note. Based on this information, the Company did not record a credit loss for this class of receivables for the year ended December 31, 2020. During the year ended December 31, 2020, the Company assessed each of its note receivables factoring in credit quality indicators such as collection experience and future expectations of performance to determine whether a credit loss should be recorded. Based on this information, the Company wrote off a $1,230 note receivable associated with amounts due from a government sponsored district at The Shoppes at St. Clair during the year ended December 31, 2020. The Company did not record any other credit losses for this class of receivables for the year ended December 31, 2020.

Commitments And Contingencies Disclosure [Abstract]
CONTINGENCIES	NOTE 16. CONTINGENCIES Litigation In April 2019, the Company entered into a settlement agreement and release with respect to the class action lawsuit filed on March 16, 2016 in the United States District Court for the Middle District of Florida by Wave Lengths Hair Salons of Florida, Inc. d/b/a Salon Adrian. Pursuant to the settlement agreement the Company set aside a common fund with a monetary and non-monetary value of $90,000 to be disbursed to class members in accordance with an agreed-upon formula that was based upon aggregate damages of $60,000. The Court granted final approval to the proposed settlement on August 22, 2019. The class members were comprised of past and current tenants at certain of the Company's shopping centers that it owns or formerly owned during the class period, which extended from January 1, 2011 through the date of preliminary court approval. Class members who are past tenants and made a valid claim pursuant to the Court's order received payment of their claims in cash. Class members who are current tenants began receiving monthly credits against rents and future charges during the three months ended June 30, 2020 and, under the terms of the settlement agreement, will continue for the following five years. Any amounts under the settlement allocated to tenants with outstanding amounts payable to the Company, including tenants which have declared bankruptcy or declare bankruptcy over the relevant period, will first be deducted from the amounts owed to the Company. All attorney’s fees and associated costs to class counsel (up to a maximum of $27,000), the incentive award to the class representative (up to a maximum of $50), and class administration costs (which are expected to not exceed $100), have been or will be funded by the common fund, which has been approved by the Court. Under the terms of the settlement agreement, the Company did not pay any dividends to holders of its common shares payable in the third and fourth quarters of 2019. The settlement agreement did not restrict the Company's ability to declare dividends payable in 2020 or in subsequent years. The Company recorded an accrued liability and corresponding litigation settlement expense of $88,150 in the three months ended March 31, 2019 related to the settlement agreement. During the year ended December 31, 2019, the Company reduced the accrued liability by an aggregate $26,396, a majority of which was related to past tenants that did not submit a claim pursuant to the terms of the settlement agreement with the remainder relating to tenants that either opted out of the lawsuit or waived their rights to their respective settlement amounts. Additionally, the Company reduced the accrued liability during the three months ended December 31, 2019 by $23,050 related to attorney and administrative fees that were paid pursuant to the settlement agreement. During the year ended December 31, 2020, the Company reduced the accrued liability by $25,157. Of this amount, $8,348 was related to monthly credits against rents and other charges for current tenants, $4,915 was paid to past tenants, $4,039 was paid to plaintiff’s counsel and the claims administrator, and $7,855 represents amounts the Company was released from pursuant to the terms of the settlement agreement. A notice of suggestion of bankruptcy was filed by the Company in this litigation on November 3, 2020. The Company received document requests in the third quarter of 2019, in the form of subpoenas, from the Securities and Exchange Commission and the Department of Justice regarding the Wave Lengths Hair Salons of Florida, Inc. litigation and other related matters. The Company continues to cooperate in these matters. Securities Litigation The Company and certain of its officers and directors were named as defendants in three putative securities class action lawsuits (collectively, the “Securities Class Action Litigation”), each filed in the United States District Court for the Eastern District of Tennessee, on behalf of all persons who purchased or otherwise acquired the Company’s securities during a specified period of time. Those cases were consolidated on July 17, 2019, under the caption In re CBL & Associates Properties, Inc. Securities Litigation The complaints filed in the Securities Class Action Litigation allege violations of the securities laws, including, among other things, that the defendants made certain materially false and misleading statements and omissions regarding the Company’s contingent liabilities, business, operations, and prospects during the periods of time specified above. The plaintiffs seek compensatory damages and attorneys’ fees and costs, among other relief, but have not specified the amount of damages sought. The outcome of these legal proceedings cannot be predicted with certainty. A notice of suggestion of bankruptcy was filed by the Company in this litigation on November 9, 2020. Certain of the Company’s current and former directors and officers were named as defendants in nine shareholder derivative lawsuits (collectively, the “Derivative Litigation”). On June 4, 2019, a shareholder filed a putative derivative complaint captioned Robert Garfield v. Stephen D. Lebovitz et al. Garfield Robert Cohen v. Stephen D. Lebovitz et al. Cohen Travis Lore v. Stephen D. Lebovitz et al. Lore City of Gainesville Cons. Police Officers’ and Firefighters Retirement Plan v. Stephen D. Lebovitz et al. , 1:19-cv-01800 (the “ Gainesville Derivative Action”), each asserting substantially similar claims purportedly on behalf of the Company against similar defendants. The Court consolidated the Garfield Derivative Action and the Cohen Derivative Action on July 17, 2019, under the caption In re CBL & Associates Properties, Inc. Derivative Litigation , 1:19-cv-01038-LPS (the " Consolidated Derivative Action"). On July 25, 2019, the Court stayed proceedings in the Consolidated Derivative Action pending resolution of an eventual motion to dismiss in the Securities Class Action Litigation. On October 14, 2019, the parties to the Gainesville Derivative Action and the Lore Derivative Action filed a joint stipulation and proposed order confirming that each of those cases is subject to the consolidation order previously entered by the Court in the Consolidated Derivative Action and that further proceedings in those cases are stayed pending resolution of an eventual motion to dismiss in the Securities Class Action Litigation. On July 22, 2019, a shareholder filed a putative derivative complaint captioned Shebitz v. Lebovitz et al. , 1:19-cv-00213, in the United States District Court for the Eastern District of Tennessee (the “ Shebitz Derivative Action”); on January 10, 2020, a shareholder filed a putative derivative complaint captioned Chatman v. Lebovitz, et al., 2020-0011-JTL, in the Delaware Chancery Court (the “Chatman Derivative Action”); on February 12, 2020, a shareholder filed a putative derivative complaint captioned Kurup v. Lebovitz, et al., 2020-0070-JTL, in the Delaware Chancery Court (the “ Kurup Derivative Action”); on February 26, 2020, a shareholder filed a putative derivative complaint captioned Kemmer v. Lebovitz, et al., 1:20-cv-00052, in the United States District Court for the Eastern District of Tennessee (the “ Kemmer Derivative Action”); and on April 14, 2020, a shareholder filed a putative derivative complaint captioned Hebig v. Lebovitz, et al., 1:19-cv-00149-JRG-CHS, in the United States District Court for the Eastern District of Tennessee (the “ Hebig Derivative Action”), each asserting substantially similar claims purportedly on behalf of the Company against similar defendants. The actions pending in Delaware Chancery Court have been consolidated into one case, and likewise, the actions pending in Delaware federal court have been consolidated into one case. The Tennessee actions have not been consolidated. On October 7, 2019, the Court stayed the Shebitz Derivative Action, pending resolution of an eventual motion to dismiss in the related Securities Class Action Litigation; the Company expects the other Derivative Actions to be stayed as well. The complaints filed in the Derivative Litigation allege, among other things, breaches of fiduciary duties, unjust enrichment, waste of corporate assets, and violations of the federal securities laws. The factual allegations upon which these claims are based are similar to the factual allegations made in the Securities Class Action Litigation, described above. The complaints filed in the Derivative Litigation seek, among other things, unspecified damages and restitution for the Company from the individual defendants, the payment of costs and attorneys’ fees, and that the Company be directed to reform certain governance and internal procedures. The outcome of these legal proceedings cannot be predicted with certainty. A notice of suggestion of bankruptcy was filed by the Company in this litigation on November 9, 2020. The Company's insurance carriers have been placed on notice of these matters. The Company is currently involved in certain other litigation that arises in the ordinary course of business, most of which is expected to be covered by liability insurance. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters using the latest information available. The Company records a liability for litigation if an unfavorable outcome is probable and the amount of loss or range of loss can be reasonably estimated. If an unfavorable outcome is probable and a reasonable estimate of the loss is a range, the Company accrues the best estimate within the range. If no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount within the range. If an unfavorable outcome is probable but the amount of the loss cannot be reasonably estimated, the Company discloses the nature of the litigation and indicates that an estimate of the loss or range of loss cannot be made. If an unfavorable outcome is reasonably possible and the estimated loss is material, the Company discloses the nature and estimate of the possible loss of the litigation. Based on current expectations, such matters, both individually and in the aggregate, are not expected to have a material adverse effect on the liquidity, results of operations, business or financial condition of the Company. See Note 2 for a discussion of the Company’s adversarial proceeding with its Bank Lenders, which has been stayed pending the confirmation of the Company’s Plan by the Bankruptcy Court. Environmental Contingencies The Company evaluates potential loss contingencies related to environmental matters using the same criteria described above related to litigation matters. Based on current information, an unfavorable outcome concerning such environmental matters, both individually and in the aggregate, is considered to be reasonably possible. However, the Company believes its maximum potential exposure to loss would not be material to its results of operations or financial condition. The Company has a master insurance policy that provides coverage through 2022 for certain environmental claims up to $10,000 per occurrence and up to $50,000 in the aggregate, subject to deductibles and certain exclusions. At certain locations, individual policies are in place. Guarantees The Operating Partnership may guaranty the debt of a joint venture primarily because it allows the joint venture to obtain funding at a lower cost than could be obtained otherwise. This results in a higher return for the joint venture on its investment, and a higher return on the Operating Partnership's investment in the joint venture. The Operating Partnership may receive a fee from the joint venture for providing the guaranty. Additionally, when the Operating Partnership issues a guaranty, the terms of the joint venture agreement typically provide that the Operating Partnership may receive indemnification from the joint venture or have the ability to increase its ownership interest. The guarantees expire upon repayment of the debt, unless noted otherwise. The following table represents the Operating Partnership's guarantees of unconsolidated affiliates' debt as reflected in the accompanying consolidated balance sheets as of December 31, 2020 and 2019: As of December 31, 2020 Obligation recorded to reflect guaranty Unconsolidated Affiliate Company's Ownership Interest Outstanding Balance Percentage Guaranteed by the Operating Partnership Maximum Guaranteed Amount Debt Maturity Date (1) December 31, 2020 December 31, 2019 West Melbourne I, LLC - Phase I 50% $ 40,177 50% $ 20,089 Feb-2021 (2) $ 201 $ 199 West Melbourne I, LLC - Phase II 50% 14,423 50% 7,212 Feb-2021 (2) 72 78 Port Orange I, LLC 50% 53,233 50% 26,617 Feb-2021 (2) 266 270 Ambassador Infrastructure, LLC 65% 9,360 100% 9,360 Jan-2021 (3) 94 101 Shoppes at Eagle Point, LLC 50% 34,585 35% (4) 12,740 Oct-2021 (5) 127 127 EastGate Storage, LLC 50% 6,500 50% (6) 3,250 Dec-2022 33 33 Self Storage at Mid Rivers, LLC 50% 5,896 50% (6) 2,994 Apr-2023 30 30 Parkdale Self Storage, LLC 50% 6,160 100% (7) 6,500 Jul-2024 65 65 Hamilton Place Self Storage, LLC 54% 6,564 50% (6) 3,501 Sep-2024 35 70 Atlanta Outlet JV, LLC 50% 4,601 100% 4,601 Nov-2023 — — Louisville Outlet Shoppes, LLC 50% 8,872 100% 8,872 Oct-2021 — — Total guaranty liability $ 923 $ 973 (1) Excludes any extension options. ( 2 ) The loan has two one-year Note 20 ). ( 3 ) Subsequent to December 31, 2020, the loan was extended (see Note 20 ). ( 4 ) The guarantee is for a fixed amount of $12,740 throughout the term of the loan, including any extensions. ( 5 ) The loan has one one-year ( 6 ) The guarantee may be reduced to 25% once certain debt and operational metrics are met. ( 7 ) The guarantee was increased to 100% as a result of the Chapter 11 Cases filed by the Company. As described in Note 2 , the filing of the Chapter 11 Cases also constituted an event of default with respect to certain property-level debt of the Operating Partnership’s subsidiaries, which may have resulted in automatic acceleration of certain monetary obligations or may give the applicable lender the right to accelerate such amounts. There was a default under each of the guaranteed loans above as a result of the filing of the Chapter 11 Cases, except for Shoppes at Eagle Point, LLC and Louisville Outlet Shoppes, LLC. The Company has guaranteed the lease performance of York Town Center, LP ("YTC"), an unconsolidated affiliate in which it owns a 50% interest, under the terms of an agreement with a third party that owns property as part of York Town Center. Under the terms of that agreement, YTC is obligated to cause performance of the third party’s obligations as landlord under its lease with its sole tenant, including, but not limited to, provisions such as co-tenancy and exclusivity requirements. Should YTC fail to cause performance, then the tenant under the third-party landlord’s lease may pursue certain remedies ranging from rights to terminate its lease to receiving reductions in rent. The Company has guaranteed YTC’s performance under this agreement up to a maximum of $22,000, which decreases by $800 annually until the guaranteed amount is reduced to $10,000. The maximum guaranteed obligation was $10,800 as of December 31, 2020. The Company entered into an agreement with its joint venture partner under which the joint venture partner has agreed to reimburse the Company 50% of any amounts it is obligated to fund under the guaranty. The Company did not record a credit loss related to this guarantee as of December 31, 2020. For the year ended December 31, 2020, the Company evaluated each guarantee, listed in the table above, individually by looking at the debt service ratio, cash flow forecasts, the performance of each loan and, where applicable, the collateral value in relation to the outstanding amount of the loan. The result of the analysis was that each loan is current, performing and, where applicable, the collateral value was greater than the outstanding amount of the loan. The Company did not record a credit loss related to these guarantee as of December 31, 2020. Performance Bonds The Company has issued various bonds that it would have to satisfy in the event of non-performance. The total amount outstanding on these bonds was $412 and $13,660 at December 31, 2020 and 2019, respectively.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended
	Dec. 31, 2020
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 17. FAIR VALUE MEASUREMENTS The Company has categorized its financial assets and financial liabilities that are recorded at fair value into a hierarchy in accordance with ASC 820, Fair Value Measurements and Disclosure Level 1 - Inputs represent quoted prices in active markets for identical assets and liabilities as of the measurement date. Level 2 - Inputs, other than those included in Level 1, represent observable measurements for similar instruments in active markets, or identical or similar instruments in markets that are not active, and observable measurements or market data for instruments with substantially the full term of the asset or liability. Level 3 - Inputs represent unobservable measurements, supported by little, if any, market activity, and require considerable assumptions that are significant to the fair value of the asset or liability. Market valuations must often be determined using discounted cash flow methodologies, pricing models or similar techniques based on the Company’s assumptions and best judgment. The asset or liability's fair value within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Under ASC 820, fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability in an orderly transaction at the measurement date and under current market conditions. Valuation techniques used maximize the use of observable inputs and minimize the use of unobservable inputs and consider assumptions such as inherent risk, transfer restrictions and risk of nonperformance. Fair Value Measurements on a Recurring Basis The carrying values of cash and cash equivalents, receivables, accounts payable and accrued liabilities are reasonable estimates of their fair values because of the short-term nature of these financial instruments. Based on the interest rates for similar financial instruments, the carrying value of mortgage and other notes receivable is a reasonable estimate of fair value. The estimated fair value of mortgage and other indebtedness was $1,091,745 and $2,970,246 at December 31, 2020 and 2019, respectively. The estimated fair value of liabilities subject to compromise was $1,606,959 at December 31, 2020. The fair value was calculated using Level 2 inputs by discounting future cash flows for mortgage and other indebtedness using estimated market rates at which similar loans would be made currently. During March 2020, the Company purchased U.S. Treasury securities that are scheduled to mature between April 2021 and June 2021. The Company has designated these securities as available-for-sale (“AFS”). The fair value of these securities was calculated based on quoted market prices in active markets and are included in the Level 1 fair value hierarchy. The Company believes the market for U.S. Treasury securities is an actively traded market given the high level of daily trading volume. In December 2020, the Company purchased additional U.S Treasury securities. The U.S. Treasury securities purchased in December 2020 matured between January 2021 and March 2021, and the Company subsequently reinvested in additional U.S. Treasury securities (see Note 20 ). The Company has also designated these as AFS. The following table sets forth information regarding the Company’s AFS securities that were measured at fair value for the year ended December 31, 2020: AFS Security Amortized Cost Allowance for credit losses (1) Total unrealized gains/(losses) Fair Value U.S. Treasury securities $ 233,053 $ — $ 18 $ 233,071 (1) U.S Treasury securities have a long history with no credit losses. Additionally, the Company notes that U.S Treasury securities are explicitly fully guaranteed by a sovereign entity that can print its own currency and that the sovereign entity’s currency is routinely held by central banks and other major financial institutions, is used in international commerce, and commonly viewed as a reserve currency, all of which qualitatively indicate that historical credit loss information should be minimally affected by current conditions and reasonable and supportable forecasts. Therefore, the Company did not record expected credit losses for its U.S Treasury securities for the year ended December 31 , 2020. Fair Value Measurements on a Nonrecurring Basis The Company measures the fair value of certain long-lived assets on a nonrecurring basis, through quarterly impairment testing or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company’s evaluation of the recoverability of long-lived assets involves the comparison of undiscounted future cash flows expected to be generated by each property over the Company’s expected remaining holding period to the respective carrying amount. The determination of whether the carrying value is recoverable also requires management to make estimates related to probability weighted scenarios impacting undiscounted cash flow models. The Company considers both quantitative and qualitative factors in its impairment analysis of long-lived assets. Significant quantitative factors include historical and forecasted information for each Property such as NOI, occupancy statistics and sales levels. Significant qualitative factors used include market conditions, age and condition of the Property and tenant mix. The quantitative and qualitative factors impact the selection of the terminal capitalization rate which is used in both an undiscounted and discounted cash flow model and the discount rate used in a discounted cash flow model. Due to the significant unobservable estimates and assumptions used in the valuation of long-lived assets that experience impairment, the Company classifies such long-lived assets under Level 3 in the fair value hierarchy.

Share Based Compensation [Abstract]
SHARE-BASED COMPENSATION	NOTE 18. SHARE-BASED COMPENSATION As of December 31, 2020, the In accordance with the provisions of ASU 2016-09, which are designed to simplify the accounting for share-based payments transactions, the Company elected to account for forfeitures of share-based payments as they occur rather than continuing to estimate them in advance. Restricted Stock Awards Under the 2012 Plan, common stock may be awarded either alone, in addition to, or in tandem with other granted stock awards. The Committee has the authority to determine eligible persons to whom common stock will be awarded, the number of shares to be awarded and the duration of the vesting period, as defined. Generally, an award of common stock vests either immediately at grant or in equal installments over a period of five years. Stock awarded to independent directors is fully vested upon grant; however, the independent directors may not transfer such shares during their board term. The Committee may also provide for the issuance of common stock under the 2012 Plan on a deferred basis pursuant to deferred compensation arrangements. The fair value of common stock awarded under the 2012 Plan is determined based on the market price of CBL’s common stock on the grant date and the related compensation expense is recognized over the vesting period on a straight-line basis. The Company may make restricted stock awards to independent directors, officers and its employees under the 2012 Plan. These awards are generally granted based on the performance of the Company and its employees. None of these awards have performance requirements other than a service condition of continued employment, unless otherwise provided. Compensation expense is recognized on a straight-line basis over the requisite service period. The share-based compensation cost related to the restricted stock awards was $2,239, $3,396 and $3,744 for 2020, 2019 and 2018, respectively. Share-based compensation cost resulting from share-based awards is recorded at the Management Company, which is a taxable entity. Share-based compensation cost capitalized as part of real estate assets was $20, $66 and $287 in 2020, 2019 and 2018, respectively. A summary of the status of the Company’s nonvested restricted stock awards as of December 31, 2020, and changes during the year ended December 31, 2020, is presented below: Shares Weighted- Average Grant-Date Fair Value Nonvested at January 1, 2020 971,846 $ 5.16 Granted 1,628,397 $ 0.86 Vested (1,052,161 ) $ 2.86 Forfeited (28,476 ) $ 4.67 Nonvested at December 31, 2020 1,519,606 $ 2.15 The weighted-average grant-date fair value of shares granted during 2020, 2019 and 2018 was $0.86, $2.20 and $4.55, respectively. The total fair value of shares vested during 2020, 2019 and 2018 was $951, $3,869 and $2,189, respectively. As of December 31, 2020, there was $1,944 of total unrecognized compensation cost related to nonvested stock awards granted under the 2012 Plan, which is expected to be recognized over a weighted-average period of 2.2 years. Long-Term Incentive Program In 2015, the Company adopted a long-term incentive program ("LTIP") for its named executive officers, which consists of performance stock unit ("PSU") awards and annual restricted stock awards, that may be issued under the 2012 Plan. The number of shares related to the PSU awards that each named executive officer may receive upon the conclusion of a three-year Beginning with the 2018 PSUs, two-thirds of the quantitative portion of the award over the performance period is based on the achievement of TSR relative to the NAREIT Retail Index while the remaining one-third is based on the achievement of absolute TSR metrics for the Company. Beginning with the 2018 PSU grant, to maintain compliance with a 200,000 share annual equity grant limit (the “Section 162(m) Grant Limit”) that was included in the 2012 Plan to satisfy the “qualified performance-based compensation” exception to the deduction limits for certain executive compensation under Section 162(m) of the Code, to the extent that a grant of PSUs could result in the issuance of a number of shares of common stock at the conclusion of the performance period that, when coupled with the number of shares of time-vesting restricted stock granted in the same year the PSUs were granted, would exceed such limit, any such excess will be converted to a cash bonus award with a value equivalent to the number of shares of common stock constituting such excess times the average of the high and low trading prices reported for CBL's common stock on the date such shares would otherwise have been issuable. In conjunction with the February 2020 approval of the 2020 LTIP grants for the named executive officers, the 2012 Stock Incentive Plan was amended to remove the Section 162(m) Grant Limit, which no longer served its original purpose because the “qualified performance-based compensation” exception to the Section 162(m) deduction limits was repealed by the 2017 tax reform legislation. However, NYSE rules also include an annual equity grant limit which effectively limits the number of shares that can be subject to stock awards to any individual named executive officer, without additional shareholder approval, to one percent (1%) of the total number of outstanding shares of the Company’s Common Stock (the “NYSE Annual Grant Limit”). To maintain NYSE compliance following elimination of the Section 162(m) Grant Limit, the Company’s Compensation Committee revised PSU awards under the LTIP, beginning in 2020, to provide that if a grant of PSUs could result in the issuance of a number of shares to a named executive officer at the conclusion of the 3-year performance period that would exceed the NYSE Annual Grant Limit, when coupled with the number of shares subject to other stock awards (e.g., the time-vesting restricted stock component of the LTIP) issued in the same year that such PSUs were issued, any such excess will instead be converted to a cash bonus award, while remaining subject to vesting conditions as described below. In August 2020, in connection with the execution of the Original RSA that is described in Note 2 , the 2020 PSUs were canceled. Based on the Company’s TSR relative to the NAREIT Retail Index for the three year performance period ended December 31, 2020, as well as the Company’s absolute TSR for such period, none of the 2018 PSUs were earned as of December 31, 2020. Any such portion of the value of the 2019 PSUs earned payable as a cash bonus will be subject to the same vesting provisions as the issuance of common stock pursuant to the PSUs. In addition, to the extent any cash is to be paid, the cash will be paid first relative to the vesting schedule, ahead of the issuance of shares of common stock with respect to the balance of PSUs earned. Annual Restricted Stock Awards Under the LTIP, annual restricted stock awards consist of shares of time-vested restricted stock awarded based on a qualitative evaluation of the performance of the Company and the named executive officer during the fiscal year. Annual restricted stock awards under the LTIP, which are included in the totals reflected in the preceding table, vest 20% on the date of grant with the remainder vesting in four equal annual installments. Outstanding restricted stock, and related grant/vesting/forfeiture activity during 2020 for awards made to named executive officers under the LTIP, is included in the information presented in the table above. Performance Stock Units The Company granted the following PSUs in the first quarter of the respective years. A summary of PSU activity as of December 31, 2020, and changes during the year ended December 31, 2020, is presented below: PSUs Weighted-Average Grant Date Fair Value 2018 PSUs granted 741,977 $ 2.63 2019 PSUs granted (1) 1,103,537 $ 2.40 Forfeited (78,934 ) $ 2.63 Outstanding at January 1, 2020 1,766,580 $ 2.96 2020 PSUs granted (2) 3,408,083 $ 0.84 2018 PSUs canceled (3) (663,043 ) $ 2.63 2020 PSUs canceled (3,408,083 ) $ 0.84 Outstanding at December 31, 2020 (4) 1,103,537 $ 3.16 (1) Includes 566,862 shares classified as a liability due to the potential cash component described above. (2) Includes 1,247,098 shares classified as a liability due to the potential cash component described above. (3) Based on the Company’s TSR relative to the NAREIT Retail Index for the three-year (4) None of the PSUs outstanding at December 31, 2020 were vested. Shares earned pursuant to the PSU awards vest 60% at the conclusion of the performance period while the remaining 40% of the PSU award vests 20% on each of the first two anniversaries thereafter. Compensation cost is recognized on a tranche-by-tranche basis using the accelerated attribution method. The resulting expense is recorded regardless of whether any PSU awards are earned as long as the required service period is met. The fair value of the potential cash component related to the 2019 PSUs is measured each reporting period, using the same methodology as was used at the initial grant date, and classified as a liability on the consolidated balance sheet as of December 31, 2020 with an adjustment to compensation expense. If the performance criterion is not satisfied at the end of the performance period for the 2019 PSUs, previously recognized compensation expense related to the liability-classified awards would be reversed as there would be no value at the settlement date. Share-based compensation expense related to the PSUs was $3,185, $1,564 and $1,364 in 2020, 2019 and 2018, respectively. Share-based compensation expense in 2020 included $2,052 of expense related to the cancellation of the 2020 PSUs. Unrecognized compensation costs related to the PSUs was $567 as of December 31, 2020, which is expected to be recognized over a weighted-average period of 1.8 years. The following table summarizes the assumptions used in the Monte Carlo simulation pricing model related to the PSUs: 2020 PSUs 2019 PSUs 2018 PSUs Grant date February 10, 2020 (1) February 11, 2019 February 12, 2018 (2) Fair value per share on valuation date (3) $ 0.84 $ 4.74 $ 4.76 Risk-free interest rate (4) 1.39 % 2.54 % 2.36 % Expected share price volatility (5) 57.98 % 60.99 % 42.02 % (1) The 2020 PSU awards were cancelled in August 2020. (2) Based on the Company’s TSR relative to the NAREIT Retail Index for the three-year performance period ended December 31, 2020, none of the 2018 PSUs were earned as of December 31, 2020. ( 3 ) The value of the PSU awards is estimated on the date of grant using a Monte Carlo simulation model. The valuation consists of computing the fair value using CBL's simulated stock price as well as TSR over a three-year ( 4 ) The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury securities in effect as of the valuation date, which is the respective grant date listed above. ( 5 ) The computation of expected volatility was based on a blend of the historical volatility of CBL's shares of common stock based on annualized daily total continuous returns over a five-year period for the 2020 PSUs and a three-year period for the 2019 and 2018 PSUs and implied volatility data based on the trailing month average of daily implied volatilities implied by stock call option contracts that were both closest to the terms shown and closest to the money.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation This Form 10-K provides separate consolidated financial statements for the Company and the Operating Partnership. Due to the Company's ability as general partner to control the Operating Partnership, the Company consolidates the Operating Partnership within its consolidated financial statements for financial reporting purposes. The notes to consolidated financial statements apply to both the Company and the Operating Partnership, unless specifically noted otherwise. The accompanying consolidated financial statements include the consolidated accounts of the Company, the Operating Partnership and their wholly owned subsidiaries, as well as entities in which the Company has a controlling financial interest or entities where the Company is deemed to be the primary beneficiary of a VIE. For entities in which the Company has less than a controlling financial interest or entities where the Company is not deemed to be the primary beneficiary of a VIE, the entities are accounted for using the equity method of accounting. Accordingly, the Company's share of the net earnings or losses of these entities is included in consolidated net income (loss). The accompanying consolidated financial statements have been prepared in accordance with GAAP. All intercompany transactions have been eliminated.
Accounting Guidance Adopted and Not Yet Adopted	Accounting Guidance Adopted Description Expected Adoption Date & Application Method Financial Statement Effect and Other Information Accounting Standards Update (“ASU”) 2016-13, Measurement of Credit Losses on Financial Instruments January 1, 2020 - Modified Retrospective The guidance replaced the current incurred loss impairment model, which reflects credit events, with a current expected credit loss model, which recognizes an allowance for credit losses based on an entity’s estimate of contractual cash flows not expected to be collected. The Company has determined that its available-for-sale debt securities, guarantees, mortgage and other notes receivable and receivables within the scope of ASC 606 fall under the scope of this standard. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-13, Fair Value Measurement January 1, 2020 - Prospective The guidance eliminates, adds and modifies certain disclosure requirements for fair value measurements. Entities no longer are required to disclose the amount of and reasons for transfers between Level 1 and 2 of the fair value hierarchy, but public companies are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract January 1, 2020 - Prospective The guidance addresses diversity in practice in accounting for the costs of implementation activities in a cloud computing arrangement that is a service contract. Under the guidance, the Company is to follow Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize and which to expense. The guidance also requires an entity to expense capitalized implementation costs over the term of the hosting arrangement and include that expense in the same line item as the fees associated with the service element of the arrangement. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. Lease Modification Q&A April 1, 2020 – Prospective In April 2020, the FASB issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance related to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under Topic 842, Leases The Company has elected to apply the relief provided under the Lease Modification Q&A and will avail itself of the election to avoid performing a lease by lease analysis for the lease concessions that were (1) granted as relief due to the COVID-19 pandemic and (2) result in the cash flows remaining substantially the same or less than the original contract. The Lease Modification Q&A had a material impact on the Company’s consolidated financial statements as of and for the year ended December 31, 2020. However, its future impact to the Company is dependent upon the extent of lease concessions granted to tenants as a result of the COVID-19 pandemic in future periods and the elections made by the Company at the time of entering such concessions. The Lease Modification Q&A allows the Company to determine accounting policy elections at a disaggregated level, and the elections should be applied consistently by either the type of concession, underlying asset class or on another reasonable basis. As a result, the Company has made the following policy elections based on the type of concession agreed to with the respective tenant. Rent Deferrals The Company will account for rental deferrals using the receivables model as described within the Lease Modification Q&A. Under the receivables model, the Company will continue to recognize lease revenue in a manner that is unchanged from the original lease agreement and continue to recognize lease receivables and rental revenue during the deferral period. Rent Abatements The Company will account for rental abatements using the negative variable income model as described within the Lease Modification Q&A. Under the negative variable income model, the Company will recognize negative variable rent for the current period reduction of rental revenue associated with any lease concessions it provide s . At December 31, 2020, the Company’s receivables included $18,526 related to receivables that had been deferred and are to be repaid generally throughout 2021, and extending for a portion of 2022. The Company granted abatements of $25,439 during the year ended December 31, 2020. The Company continues to assess rent relief requests from its tenants but is unable to predict the resolution or impact of these discussions. For agreements that are currently under negotiation, the Company does not expect the impact to be material.

Real Estate Assets	Real Estate Assets The Company capitalizes predevelopment project costs paid to third parties. All previously capitalized predevelopment costs are expensed when it is no longer probable that the project will be completed. Once development of a project commences, all direct costs incurred to construct the project, including interest and real estate taxes, are capitalized. Additionally, certain general and administrative expenses are allocated to the projects and capitalized based on the amount of time applicable personnel work on the development project. Ordinary repairs and maintenance are expensed as incurred. Major replacements and improvements are capitalized and depreciated over their estimated useful lives. All acquired real estate assets have been accounted for using the acquisition method of accounting and accordingly, the results of operations are included in the consolidated statements of operations from the respective dates of acquisition. The Company allocates the purchase price to (i) tangible assets, consisting of land, buildings and improvements, as if vacant, and tenant improvements, and (ii) identifiable intangible assets and liabilities, generally consisting of above-market leases, in-place leases and tenant relationships, which are included in intangible lease assets and other assets, and below-market leases, which are included in accounts payable and accrued liabilities. The Company uses estimates of fair value based on estimated cash flows, using appropriate discount rates, and other valuation techniques to allocate the purchase price to the acquired tangible and intangible assets. Liabilities assumed generally consist of mortgage debt on the real estate assets acquired. Assumed debt is recorded at its fair value based on estimated market interest rates at the date of acquisition. The Company expects its future acquisitions will be accounted for as acquisitions of assets in which related transaction costs will be capitalized. Depreciation is computed on a straight-line basis over estimated lives of 40 years for buildings, 10 to 20 years for certain improvements and 7 to 10 years for equipment and fixtures. Tenant improvements are capitalized and depreciated on a straight-line basis over the term of the related lease. Lease-related intangibles from acquisitions of real estate assets are generally amortized over the remaining terms of the related leases. The amortization of above- and below-market leases is recorded as an adjustment to rental revenue, while the amortization of all other lease-related intangibles is recorded as amortization expense. Any difference between the face value of the debt assumed and its fair value is amortized to interest expense over the remaining term of the debt using the effective interest method. The Company’s intangibles and their balance sheet classifications as of December 31, 2020 and 2019, are summarized as follows: December 31, 2020 December 31, 2019 Cost Accumulated Amortization Cost Accumulated Amortization Intangible lease assets and other assets: Above-market leases $ 18,416 $ (16,395 ) $ 21,098 $ (18,559 ) In-place leases 59,472 (53,790 ) 66,309 (58,559 ) Tenant relationships 34,630 (7,909 ) 38,880 (10,834 ) Accounts payable and accrued liabilities: Below-market leases 42,274 (36,224 ) 46,554 (38,052 ) These intangibles are related to specific tenant leases. Should a termination occur earlier than the date indicated in the lease, the related unamortized intangible assets or liabilities, if any, related to the lease are recorded as expense or income, as applicable. The total net amortization expense of the above intangibles was $1,460, $4,506 and $13,282 in 2020, 2019 and 2018, respectively. The estimated total net amortization expense for the next five succeeding years is $1,326 in 2021, $1,071 in 2022, $872 in 2023, $854 in 2024 and $817 in 2025. Total interest expense capitalized was $1,640, $2,504 and $3,225 in 2020, 2019 and 2018, respectively.
Accounts Receivable	Accounts Receivable Receivables include amounts billed and currently due from tenants pursuant to lease agreements and receivables attributable to straight-line rents associated with those lease agreements. Individual leases where the collection of rents is in dispute are assessed for collectability based on management’s best estimate of collection considering the anticipated outcome of the dispute. Individual leases that are not in dispute are assessed for collectability and upon the determination that the collection of rents over the remaining lease term is not probable, accounts receivable are reduced as an adjustment to rental revenues. Revenue from leases where collection is deemed to be less than probable is recorded on a cash basis until collectability is determined to be probable. Further, management assesses whether operating lease receivables, at a portfolio level, are appropriately valued based upon an analysis of balances outstanding, historical collection levels and current economic trends. An allowance for the uncollectable portion of the portfolio is recorded as an adjustment to rental revenues. Management’s estimate of the collectability of accounts receivable from tenants is based on the best information available to management at the time of evaluation. The duration of the COVID-19 pandemic and its impact on the Company’s tenants’ ability to pay rents has caused uncertainty in the Company’s ongoing ability to collect rents when due. Considering the potential impact of these uncertainties, management’s collection assessment also took into consideration the type of retailer, billing disputes, lease negotiation status and executed deferral or abatement agreements, as well as recent rent collection experience and tenant bankruptcies based on the best information available to management at the time of evaluation. For the year ended December 31, 2020 and 2019, the Company recorded $48,240 and $3,463, respectively, associated with uncollectable revenues, which includes $5,603 for straight line rent receivables for the year ended December 31, 2020. The following table sets forth the activity for the Company’s allowance for doubtful accounts: Year Ended December 31, 2019 2018 (1) Tenant receivables - allowance for doubtful accounts: Balance, beginning of year $ 2,337 $ 2,011 Additions in allowance charged to expense — 4,817 Bad debts charged against allowance (2,337 ) (4,491 ) Balance, end of year $ — $ 2,337 Year Ended December 31, 2019 2018 (1) Other receivables - allowance for doubtful accounts: Balance, beginning of year $ — $ 838 Additions in allowance charged to expense — — Bad debts charged against allowance — (838 ) Balance, end of year $ — $ — (1) Note 5 .
Carrying Value of Long-Lived Assets	Carrying Value of Long-Lived Assets The Company evaluates its real estate assets for impairment indicators whenever events or changes in circumstances indicate that the carrying value of any of its long-lived assets may not be recoverable. Furthermore, this evaluation is conducted no less frequently than quarterly, irrespective of changes in circumstances. The prolonged outbreak of the COVID-19 pandemic resulted in sustained closure of the Company’s properties for a period of time, as well as the cessation of the operations of certain of its tenants, which has resulted and will likely continue to result in a reduction in the revenues and cash flows of many of its properties due to the adverse financial impacts on its tenants, as well as reductions in other sources of income generated by its properties. In addition to reduced revenues, the Company’s ability to obtain sufficient financing for such properties may be impaired as well as its ability to lease or re-lease properties as a result of worsening market and economic conditions resulting from the COVID-19 pandemic. As of December 31, 2020, the Company’s evaluation of impairment of real estate assets considered its estimate of cash flow declines caused by the COVID-19 pandemic, but its other assumptions, including estimated hold period, were generally unchanged given the highly uncertain environment. The worsening of estimated future cash flows due to a change in the Company’s plans, policies, or views of market and economic conditions as it relates to one or more of its properties adversely impacted by the COVID-19 pandemic could result in the recognition of substantial impairment charges on its assets, which could adversely impact its financial results. For the year ended December 31, 2020, the Company recorded impairment charges of $213,358 related to six of its malls. As of December 31, 2020, seven other properties had impairment indicators; however, based on the Company’s plans with respect to those properties and the economic environment as of December 31, 2020, no additional impairment charges were recorded.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with original maturities of three months or less as cash equivalents.
Restricted Cash	Restricted Cash Restricted cash of $59,941 and $26,242 was included in intangible lease assets and other assets at December 31, 2020 and 2019, respectively. The $59,941 in restricted cash at December 31, 2020 related to cash held in escrow accounts for insurance, real estate taxes, capital expenditures and tenant allowances as required by the terms of certain mortgage notes payable, as well as amount s related to cash management agreements with the Company’s lenders that are designated for debt service and operating expense obligations .
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Company evaluates its joint venture arrangements to determine whether they should be recorded on a consolidated basis. The percentage of ownership interest in the joint venture, an evaluation of control and whether a VIE exists are all considered in the Company’s consolidation assessment. Initial investments in joint ventures that are in economic substance a capital contribution to the joint venture are recorded in an amount equal to the cash contributed by the Company and the fair value of any real estate contributed. Initial investments in joint ventures that are in economic substance the sale of a portion of the Company’s interest in the real estate are accounted for as a contribution of real estate recorded in an amount equal to the fair value of the ownership interest retained and as a sale of real estate with profit recognized to the extent of the other joint venture partners’ interests in the joint venture. Profit recognition assumes the Company has no commitment to reinvest with respect to the percentage of the real estate sold and the accounting requirements of the full accrual method are met. The Company accounts for its investment in joint ventures where it owns a noncontrolling interest or where it is not the primary beneficiary of a VIE using the equity method of accounting. Under the equity method, the Company’s cost of investment is adjusted for additional contributions to and distributions from the unconsolidated affiliate, as well as its share of equity in the earnings of the unconsolidated affiliate. Generally, distributions of cash flows from operations and capital events are first made to partners to pay cumulative unpaid preferences on unreturned capital balances and then to the partners in accordance with the terms of the joint venture agreements. The Company evaluates its investment in unconsolidated affiliates for impairment indicators whenever events or changes in circumstances indicate that the carrying value of its investment may not be recoverable. The Company’s evaluation of whether an investment in an unconsolidated affiliate has incurred a loss in value that is other than temporary includes an assessment of the expected return generated from the property or properties held within the investment, and the Company’s intent and ability to retain the investment for a period of time to allow for full recovery. Furthermore, this evaluation is conducted no less frequently than quarterly, irrespective of changes in circumstances. The prolonged outbreak of the COVID-19 pandemic resulted in sustained closure of the Company’s properties for a period of time, as well as the cessation of the operations of certain of its tenants, which has resulted and will likely continue to result in a reduction in the revenues and cash flows of many of its properties due to the adverse financial impacts on its tenants, as well as reductions in other sources of income generated by its properties. In addition to reduced revenues, the Company’s ability to obtain sufficient financing for such properties may be impaired as well as its ability to lease or re-lease properties as a result of worsening market and economic conditions resulting from the COVID-19 pandemic. As of December 31, 2020 and 2019, no impairment charges were recorded. In 2018, the Company recorded an impairment of $1,022 as its share of the loss on impairment recognized by an unconsolidated joint venture. The Company recorded a gain on deconsolidation of investments of $67,242 in 2019. See Note 8
Deferred Financing Costs	Deferred Financing Costs During 2020, as a result of the Chapter 11 Cases, unamortized financing costs of $16,779 related to the Company's secured credit facility and senior unsecured notes were charged to expense and were recorded as “Reorganization items” within the Company’s consolidated statements of operations. Unamortized financing costs related to the secured line of credit of
Revenue Recognition	Revenue Recognition See Note 4 for a description of the Company's revenue streams.
Gain on Sales of Real Estate Assets	Gain on Sales of Real Estate Assets Gains on the sale of real estate assets, like all non-lease related revenue, are subject to a five-step model requiring that the Company identify the contract with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract, and recognize revenue upon satisfaction of the performance obligations. In circumstances where the Company contracts to sell a property with material post-sale involvement, such involvement must be accounted for as a separate performance obligation in the contract and a portion of the sales price allocated to each performance obligation. When the post-sale involvement performance obligation is satisfied, the portion of the sales price allocated to it will be recognized as gain on sale of real estate assets. Property dispositions with no continuing involvement will continue to be recognized upon closing of the sale.
Income Taxes	Income Taxes The Company is qualified as a REIT under the provisions of the Internal Revenue Code. To maintain qualification as a REIT, the Company is required to distribute at least 90% of its taxable income to shareholders and meet certain other requirements. As a REIT, the Company is generally not liable for federal corporate income taxes. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal and state income taxes on its taxable income at regular corporate tax rates. Even if the Company maintains its qualification as a REIT, the Company may be subject to certain state and local taxes on its income and property, and to federal income and excise taxes on its undistributed income. State tax expense was $2,882, $3,682 and $4,147 during 2020, 2019 and 2018, respectively. The Company has also elected taxable REIT subsidiary status for some of its subsidiaries. This enables the Company to receive income and provide services that would otherwise be impermissible for REITs. For these entities, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if the Company believes all or some portion of the deferred tax asset may not be realized. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in the Company’s judgment about the realizability of the related deferred tax asset is included in income or expense, as applicable. The Company recorded an income tax benefit (provision) as follows for the years ended December 31, 2020, 2019 and 2018: Year Ended December 31, 2020 2019 2018 Current tax provision $ (2,278 ) $ (485 ) $ (1,354 ) Deferred tax benefit (provision) (14,558 ) (2,668 ) 2,905 Income tax benefit (provision) $ (16,836 ) $ (3,153 ) $ 1,551 In 2020, the Company recorded a full deferred tax asset valuation allowance of $16,206, which left a balance of zero as a net deferred tax asset at December 31, 2020. The Company had a net deferred tax asset of $15,117 at December 31, 2019. In 2018, the Company recorded a cumulative effect adjustment in the amount of $11,433 related to the January 1, 2018 adoption of ASU 2016-16. The net deferred tax asset at December 31, 2019 is included in intangible lease assets and other assets. These deferred tax balances primarily consist of differences between book and tax related to the basis of real estate assets, depreciation expense and operating expenses, as well as net operating loss carryforwards. As of December 31, 2020, tax years that generally remain subject to examination by the Company’s major tax jurisdictions include 2020, 2019, 2018 and 2017. The Company reports any income tax penalties attributable to its properties as property operating expenses and any corporate-related income tax penalties as general and administrative expenses in its consolidated statements of operations. In addition, any interest incurred on tax assessments is reported as interest expense. The Company incurred nominal interest and penalty amounts in 2020, 2019 and 2018.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s tenants include national, regional and local retailers. Financial instruments that subject the Company to concentrations of credit risk consist primarily of tenant receivables. The Company generally does not obtain collateral or other security to support financial instruments subject to credit risk, but monitors the credit standing of tenants. The Company derives a substantial portion of its rental income from various national and regional retail companies; however, no single tenant collectively accounted for more than 4.5% of the Company’s total consolidated revenues in 2020.
Earnings per Share and Earnings per Unit	Earnings per Share and Earnings per Unit Earnings per Share of the Company Basic earnings per share ("EPS") is computed by dividing net income (loss) attributable to common shareholders by the weighted-average number of common shares outstanding for the period. Diluted EPS assumes the issuance of common stock for all potential dilutive common shares outstanding. The limited partners’ rights to convert their noncontrolling interests in the Operating Partnership into shares of common stock are not dilutive. Performance stock units ("PSUs") are contingently issuable common shares and are included in earnings per share if the effect is dilutive. See Note 18 for a description of the long-term incentive program that these units relate to. There were no potential dilutive common shares and no anti-dilutive shares for the year ended December 31, 2020. The effect of 102,820 contingently issuable common shares related to PSUs for the year ended December 31, 2018 were excluded from the computation of diluted EPS because the effect would have been anti-dilutive. Earnings per Unit of the Operating Partnership Basic earnings per unit (“EPU”) is computed using the two-class method. The two-class method is required when either (i) participating securities or (ii) multiple classes of common stock exists. The Operating Partnership’s special common units, and common units issued upon the conversion or redemption of special common units, meet the definition of participating securities as these units have the contractual right and obligation to share in the Operating Partnership’s net income (loss) and distributions. Under this approach net income (loss) attributable to common unitholders is reduced by the amount of distributions made (declared) to all common unitholders and by the amount of distributions that are required to be made (declared and undeclared) to special common unitholders. Distributed and undistributed earnings is subsequently divided by the weighted-average number of common and special common units outstanding for the period to compute basic EPU for each unit. Undistributed losses are allocated 100 percent to common units, other than common units issued upon the conversion or redemption of special common units. The special common units, and common units issued upon the conversion or redemption of special common units, only participate in undistributed losses in the event of a liquidation. Diluted EPU is computed by considering either the two-class method or the if-converted method, whichever results in more dilution. The if-converted method assumes the issuance of common units for all potential dilutive special common units outstanding. Due to the loss position (negative earnings) of the Operating Partnership for the years ended December 31, 2020 and 2019 all special common units, and common units issued upon the conversion or redemption of special common units, are antidilutive. The calculation of diluted EPU through the if-converted method would reduce the loss per share (as a result of an increase number of shares in the denominator) for the common units. Therefore in a loss position diluted EPU is equal to basic EPU. There were no potential dilutive common units and there were no anti-dilutive units other than the special common units, and common units issued upon the conversion or redemption of special common units, outstanding for the years ended December 31, 2020, 2019 and 2018.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires 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 reported period. Actual results could differ from those estimates.

Accounting Policies [Abstract]
Schedule of New Accounting Pronouncements and Changes in Accounting Principles	Accounting Guidance Adopted Description Expected Adoption Date & Application Method Financial Statement Effect and Other Information Accounting Standards Update (“ASU”) 2016-13, Measurement of Credit Losses on Financial Instruments January 1, 2020 - Modified Retrospective The guidance replaced the current incurred loss impairment model, which reflects credit events, with a current expected credit loss model, which recognizes an allowance for credit losses based on an entity’s estimate of contractual cash flows not expected to be collected. The Company has determined that its available-for-sale debt securities, guarantees, mortgage and other notes receivable and receivables within the scope of ASC 606 fall under the scope of this standard. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-13, Fair Value Measurement January 1, 2020 - Prospective The guidance eliminates, adds and modifies certain disclosure requirements for fair value measurements. Entities no longer are required to disclose the amount of and reasons for transfers between Level 1 and 2 of the fair value hierarchy, but public companies are required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. ASU 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract January 1, 2020 - Prospective The guidance addresses diversity in practice in accounting for the costs of implementation activities in a cloud computing arrangement that is a service contract. Under the guidance, the Company is to follow Subtopic 350-40 on internal-use software to determine which implementation costs to capitalize and which to expense. The guidance also requires an entity to expense capitalized implementation costs over the term of the hosting arrangement and include that expense in the same line item as the fees associated with the service element of the arrangement. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements or disclosures. Lease Modification Q&A April 1, 2020 – Prospective In April 2020, the FASB issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance related to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under Topic 842, Leases The Company has elected to apply the relief provided under the Lease Modification Q&A and will avail itself of the election to avoid performing a lease by lease analysis for the lease concessions that were (1) granted as relief due to the COVID-19 pandemic and (2) result in the cash flows remaining substantially the same or less than the original contract. The Lease Modification Q&A had a material impact on the Company’s consolidated financial statements as of and for the year ended December 31, 2020. However, its future impact to the Company is dependent upon the extent of lease concessions granted to tenants as a result of the COVID-19 pandemic in future periods and the elections made by the Company at the time of entering such concessions. The Lease Modification Q&A allows the Company to determine accounting policy elections at a disaggregated level, and the elections should be applied consistently by either the type of concession, underlying asset class or on another reasonable basis. As a result, the Company has made the following policy elections based on the type of concession agreed to with the respective tenant. Rent Deferrals The Company will account for rental deferrals using the receivables model as described within the Lease Modification Q&A. Under the receivables model, the Company will continue to recognize lease revenue in a manner that is unchanged from the original lease agreement and continue to recognize lease receivables and rental revenue during the deferral period. Rent Abatements The Company will account for rental abatements using the negative variable income model as described within the Lease Modification Q&A. Under the negative variable income model, the Company will recognize negative variable rent for the current period reduction of rental revenue associated with any lease concessions it provide s . At December 31, 2020, the Company’s receivables included $18,526 related to receivables that had been deferred and are to be repaid generally throughout 2021, and extending for a portion of 2022. The Company granted abatements of $25,439 during the year ended December 31, 2020. The Company continues to assess rent relief requests from its tenants but is unable to predict the resolution or impact of these discussions. For agreements that are currently under negotiation, the Company does not expect the impact to be material.

The valuation consists of computing the fair value using CBL's simulated stock price as well as TSR over a three-year ( 4 ) The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury securities in effect as of the valuation date, which is the respective grant date listed above. ( 5 ) The computation of expected volatility was based on a blend of the historical volatility of CBL's shares of common stock based on annualized daily total continuous returns over a five-year period for the 2020 PSUs and a three-year period for the 2019 and 2018 PSUs and implied volatility data based on the trailing month average of daily implied volatilities implied by stock call option contracts that were both closest to the terms shown and closest to the money.
