Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies General The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), with intercompany transactions between consolidated subsidiaries eliminated. In accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as issued by the Securities and Exchange Commission (the SEC), these Condensed Consolidated Financial Statements do not include all of the information and disclosures required by GAAP for complete financial statements. Readers of this quarterly report on Form 10-Q (Quarterly Report) should refer to The Howard Hughes Corporation (HHC or the Company) audited Consolidated Financial Statements, which are included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2020, filed with the SEC on February 25, 2021 (the Annual Report). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows and equity for the interim periods have been included. The results for the three and nine months ended September 30, 2021, are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, and future fiscal years. Certain amounts in the 2020 Condensed Consolidated Balance Sheet have been reclassified to conform to the current presentation. Specifically, the Company reclassified straight-line rent from Prepaid expenses and other assets, net to Accounts Receivable, net. Management has evaluated for disclosure or recognition all material events occurring subsequent to the date of the Condensed Consolidated Financial Statements up to the date and time this Quarterly Report was filed. Douglas Ranch Acquisition In October 2021, HHC announced the launch of Douglas Ranch, a new large-scale master planned community in the city of Buckeye in the West Valley of Phoenix, Arizona. The Company closed on the all-cash purchase of approximately 33,810 acres for a purchase price of $541.0 million. The purchase price includes an option for the seller to re-acquire a 50% interest in the property, with $33.8 million of the purchase price being credited to the Seller upon exercise of the option. If the option is not exercised by the seller, the $33.8 million will be returned to the Company. Simultaneous with the land acquisition, the Company closed on the acquisition of a 50% interest in Trillium Development Holding Company, LLC, for $59.0 million. Trillium Development Holding Company, LLC owns approximately 3,029 acres of land in Buckeye, Arizona. Share Repurchase Program In October 2021, the board of directors of The Howard Hughes Corporation, authorized a share repurchase program, pursuant to which the Company may, from time to time, purchase up to $250.0 million of its common stock through open market transactions. The date and time of such repurchases will depend upon market conditions. All repurchases will be made in compliance with, and at such times as permitted by, federal securities laws and may be suspended or discontinued at any time. The new program replaces the Company’s prior share repurchase program adopted in October 2019, which authorized the repurchase of up to $100.0 million of its common stock. Under this program, the Company had repurchased an aggregate value of $53.9 million of its common stock as of September 30, 2021. COVID-19 Pandemic The 2020 outbreak of the novel strain of the coronavirus (COVID-19) resulted in a global slowdown of economic activity including worldwide travel restrictions, prohibitions of non-essential work activities, and the disruption and shutdown of businesses, all of which resulted in significant uncertainty in global financial markets and a material adverse impact on the Company’s financial performance in fiscal 2020, particularly in the Operating Asset and Seaport segments. Many states began easing quarantine protocols near the end of the second quarter of 2020, which allowed most of the Company’s retail and hospitality properties to resume operations on a limited basis. While COVID-19 has adversely impacted all business segments during 2020 and 2021, the Company’s performance notably improved during the second half of 2020. This improvement has continued through the third quarter of 2021. The extent to which COVID-19 continues to impact the Company will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the actions taken to contain the pandemic or mitigate its impact, such as the speed and effectiveness of vaccine and treatment developments and their deployment, potential mutations of COVID-19, and the direct and indirect economic effects of the pandemic and containment measures. Restricted Cash Restricted cash reflects amounts segregated in escrow accounts in the name of the Company, primarily related to escrowed condominium deposits by buyers and other amounts related to taxes, insurance and legally restricted security deposits and leasing costs. Accounts Receivable, net On a quarterly basis, management reviews tenant rents, tenant recoveries and straight-line rent assets for collectability. As required under Accounting Standards Codification (ASC) 842 - Leases, this analysis includes a review of past due accounts and considers factors such as the credit quality of tenants, current economic conditions and changes in customer payment trends. When full collection of a lease receivable or future lease payment is not probable, a reserve for the receivable balance is charged against rental revenue and future rental revenue is recognized on a cash basis. Due to the continued impacts of COVID-19 on the collectability of tenant receivables, the Company determined full collection of outstanding tenant rents and recoveries was not probable for some retail tenants. In addition, the Company determined that a reserve for estimated losses under ASC 450 - Contingencies is required as the amount is probable and can be reasonably estimated. The following table represents the components of Accounts Receivable, net of amounts considered uncollectible, in the accompanying Condensed Consolidated Balance Sheets: thousands September 30, 2021 December 31, 2020 Tenant receivables $ 9,150 $ 4,339 Straight-line rent receivables 68,709 59,288 Other receivables 4,076 3,099 Accounts receivable, net (a) $ 81,935 $ 66,726 (a) As of September 30, 2021, the total reserve balance for amounts considered uncollectible was $29.9 million, comprised of $26.4 million related to ASC 842 and $3.6 million related to ASC 450. As of December 31, 2020, the total reserve balance was $33.0 million, comprised of $27.3 million related to ASC 842 and $5.7 million related to ASC 450. The following table summarizes the impacts of the ASC 842 and ASC 450 reserves in the accompanying Condensed Consolidated Statements of Operations: Three Months Ended Nine Months Ended thousands Income Statement Location 2021 2020 2021 2020 ASC 842 reserve Rental revenue $ (610) $ 9,718 $ 751 $ 16,937 ASC 450 reserve Provision for (recovery of) doubtful accounts (10) 1,673 (2,249) 6,069 Total impact $ (620) $ 11,391 $ (1,498) $ 23,006 Temporary Business Closures During the first half of 2020, the Company experienced closures of its Seaport retail and food and beverage assets as well as its three hotels in The Woodlands. The Company reopened The Woodlands Resort in May 2020, the Embassy Suites at Hughes Landing in June 2020 and The Westin at The Woodlands in July 2020. As a result, occupancy levels rose throughout the second half of 2020 and into 2021 but remained lower than levels achieved prior to the pandemic. On September 16, 2021, the Company completed the sale of all three hospitality assets for $252.0 million, resulting in a gain on sale of $39.1 million . Refer to Note 3 - Dispositions for additional information. Many of the Seaport retail and food and beverage assets resumed operations in the third quarter of 2020, on a limited basis. Most remaining restrictions were lifted in June of 2021; however, many businesses at the Seaport continue to operate at less than full capacity primarily due to labor shortages. The 2020 Seaport summer concert series was cancelled and in its place a new concept at the Pier 17 rooftop was launched called The Greens, which continued through the end of first quarter of 2021. The Greens concept returned in May 2021 to complement the summer concert series, which began in July 2021, and ran through mid-October 2021. The Greens concept and 2021 concert series continue to generate high customer demand for the outdoor venue. Additionally, in April 2021, Momofuku reopened the Ssäm Bar in the space previously occupied by its former concept, Bar Wayō and Andrew Carmellini’s Noho Hospitality opened Mister Dips in May 2021 and Carne Mare in June 2021. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The estimates and assumptions include, but are not limited to, capitalization of development costs, provision for income taxes, recoverable amounts of receivables and deferred tax assets, initial valuations of tangible and intangible assets acquired and the related useful lives of assets upon which depreciation and amortization is based. Estimates and assumptions have also been made with respect to future revenues and costs, debt and options granted. In particular, Master Planned Communities (MPC) cost of sales estimates are highly judgmental as they are sensitive to cost escalation, sales price escalation and lot absorption, which are subject to judgment and affected by expectations about future market or economic conditions. Actual results could differ from these and other estimates. In addition, these estimates may change in the near term due to the continued demands and constraints on the Company’s supply chain resulting from the COVID-19 pandemic. Noncontrolling Interests As of September 30, 2021 and December 31, 2020, noncontrolling interests are related to the Ward Village Homeowners’ Associations (HOAs). All revenues and expenses related to the HOAs are attributable to noncontrolling interests and do not impact net income attributable to common stockholders. For additional information on redeemable noncontrolling interest refer to Note 2 - Real Estate and Other Affiliates . Financial Instruments - Credit Losses The Company is exposed to credit losses through the sale of goods and services to the Company’s customers. Receivables held by the Company primarily relate to short-term trade receivables and financing receivables, which include Municipal Utility District (MUD) receivables, Special Improvement District (SID) bonds, TIF receivables, net investments in lease receivables, and notes receivable. The Company assesses its exposure to credit loss based on historical collection experience and future expectations by portfolio segment. Historical collection experience is evaluated on a quarterly basis by the Company. The amortized cost basis of financing receivables, consisting primarily of MUD receivables, totaled $482.6 million as of September 30, 2021, including accrued interest of $21.0 million. There has been no material activity in the allowance for credit losses for financing receivables for the nine months ended September 30, 2021. Financing receivables are considered to be past due once they are 30 days contractually past due under the terms of the agreement. The Company does not have significant receivables that are past due or on nonaccrual status. There have been no significant write-offs or recoveries of amounts previously written off during the current period for financing receivables. Recently Issued Accounting Standards The following is a summary of recently issued and other notable accounting pronouncements that relate to the Company’s business. ASU 2020-04, Reference Rate Reform The amendments in this Update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform when certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has applied certain optional expedients that are retained through the end of the hedging relationship. The amendments in this Update are effective as of March 12, 2020, through December 31, 2022. The guidance in Accounting Standards Update (ASU) 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the first quarter of 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedge transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued.

Equity Method Investments and Joint Ventures [Abstract]
Real Estate and Other Affiliates	2. Real Estate and Other Affiliates As of September 30, 2021, the Company does not consolidate the investments below as it does not have the power to direct the activities that most significantly impact the economic performance of the ventures and does not have controlling interests in these investments. As a result, the Company reports its interests in accordance with the equity method. As of September 30, 2021, approximately $634.5 million of indebtedness was secured by the properties owned by the Company’s real estate and other affiliates, of which the Company’s share was $292.8 million based on economic ownership. All of this indebtedness is without recourse to the Company, with the exception of $100.6 million related to 110 North Wacker. Equity investments in real estate and other affiliates are reported as follows: Economic/Legal Ownership Carrying Value Share of Earnings/Dividends September 30, December 31, September 30, December 31, Three Months Ended Nine Months Ended thousands except percentages 2021 2020 2021 2020 2021 2020 2021 2020 Equity Method Investments Operating Assets: 110 North Wacker (a) see below see below $ 224,004 $ 261,143 $ (15,954) — $ (42,966) $ — The Metropolitan Downtown Columbia (b) 50 % 50 % — — (233) 215 (122) 637 Stewart Title of Montgomery County, TX 50 % 50 % 4,424 3,924 715 375 1,349 878 Woodlands Sarofim #1 20 % 20 % 3,207 3,120 34 32 87 96 m.flats/TEN.M 50 % 50 % 563 1,247 330 340 966 496 Master Planned Communities: The Summit (c) see below see below 39,196 96,300 8,277 (1,563) 54,568 4,403 Seaport Mr. C Seaport (d) — % — % — — — — — (6,900) The Lawn Club (e) see below see below 123 — — — — — Ssäm Bar (Momofuku) (f) see below see below 6,142 7,101 (1,009) (288) (1,697) (2,064) Strategic Developments: Circle T Ranch and Power Center (g) — % — % — — — 216 — 891 HHMK Development 50 % 50 % 10 10 — — — — KR Holdings 50 % 50 % 222 347 (8) (7) (125) (44) 110 North Wacker (a) see below see below — — — 267,518 — 267,518 277,891 373,192 (7,848) 266,838 12,060 265,911 Other equity investments (h) 3,952 3,953 — — 3,755 3,724 Investments in real estate and other affiliates $ 281,843 $ 377,145 $ (7,848) $ 266,838 $ 15,815 $ 269,635 (a) During the third quarter of 2020, 110 North Wacker was completed and placed in service. This triggered a reconsideration event that resulted in the deconsolidation of 110 North Wacker and the recognition of the retained equity method investment at fair market value. The $267.5 million gain on deconsolidation was recorded in the Strategic Developments segment and the equity method investment was then transferred from the Strategic Development segment to the Operating Asset segment. Refer to the discussion below for additional details. (b) The Metropolitan Downtown Columbia was in a deficit position of $11.0 million at September 30, 2021, and $5.0 million at December 31, 2020, due to distributions from operating cash flows in excess of basis. These deficit balances are presented in Accounts payable and accrued expenses at September 30, 2021, and December 31, 2020. The increase in the deficit balance is primarily due to a $5.0 million distribution in the third quarter of 2021. (c) The decrease in investment balance is primarily due to distributions of $100.5 million received during the second quarter of 2021 and $10.0 million received during the third quarter of 2021 partially offset by an increase in income. Refer to discussion below for details on the ownership structure. (d) During the third quarter of 2020, the Company completed the sale of its 35% equity investment in Mr. C Seaport. (e) Refer to the discussion below for details on the ownership structure. (f) During the first quarter of 2021, Bar Wayō was rebranded as Ssäm Bar. Refer to the discussion below for details on the ownership structure. (g) During the fourth quarter of 2020, the Company completed the sale of its 50% equity investment in Circle T Ranch and Power Center. (h) Other equity investments represent equity investments not accounted for under the equity method. The Company elected the measurement alternative as these investments do not have readily determinable fair values. There were no impairments, or upward or downward adjustments to the carrying amounts of these securities either during current year or cumulatively. Significant activity for investments in real estate and other affiliates and the related accounting considerations are described below. 110 North Wacker The Company formed a partnership with a local developer (the Partnership) during the second quarter of 2017. During the second quarter of 2018, the Partnership executed an agreement with USAA related to 110 North Wacker (collectively, the local developer and USAA are the Partners) to construct and operate the building at 110 North Wacker (the Venture). The Partnership was determined to be a variable interest entity (VIE), and as the Company has the power to direct the activities of the Partnership that most significantly impact its economic performance, the Company is considered the primary beneficiary and consolidates the Partnership. Additionally, the noncontrolling interest holder has the right to require the Company to purchase its interest in the Partnership if the Venture has not been sold or refinanced (with distributions made to the local developer and Company sufficient to repay all capital contributions) at the later of (1) the third anniversary of the issuance of the certificate of occupancy for the project or (2) the fifth anniversary of the effective date of the Partnership's LLC agreement. Therefore, the local developer’s redeemable noncontrolling interest in the Partnership is presented as temporary equity on the Condensed Consolidated Balance Sheets. As of September 30, 2021, the time restriction has not been met, and the Company believes it is not probable that the put will be redeemed. As such, the redeemable noncontrolling interest is measured at the initial carrying value plus net income (loss) attributable to the noncontrolling interest and is not adjusted to fair value. The following table presents changes in Redeemable noncontrolling interest: thousands Redeemable Noncontrolling Interest Balance as of December 31, 2020 $ 29,114 Net income (loss) attributable to noncontrolling interest (4,296) Share of investee’s other comprehensive income 582 Balance as of September 30, 2021 $ 25,400 Balance as of December 31, 2019 $ — Reclassification of redeemable noncontrolling interest from permanent equity 6,091 Net income (loss) attributable to noncontrolling interest 24,270 Balance as of September 30, 2020 $ 30,361 Upon execution of the Venture in the second quarter of 2018, the Company contributed land with a carrying value of $33.6 million and an agreed upon fair value of $85.0 million, the local developer contributed $5.0 million in cash and USAA contributed $64.0 million in cash. USAA was required to fund up to $105.6 million in addition to its initial contribution. HHC and the local developer also had additional cash funding requirements and contributed $9.8 million and $1.1 million, respectively, during 2018. The Company and its Partners entered into a construction loan agreement further described in Note 6 - Mortgages, Notes and Loans Payable, Net . Any further cash funding requirements by the Partnership were eliminated when the construction loan was increased on May 23, 2019. Concurrently with the increase in the construction loan, USAA agreed to fund an additional $8.8 million, for a total commitment of $178.4 million. No changes were made to the rights of either the Company or the Partners under the construction loan agreement. The Company concluded that the Venture was within the scope of the VIE model, and that it was the primary beneficiary of the Venture during the development phase of the project because it had the power to direct activities that most significantly impact the Venture’s economic performance; however, upon the building’s completion, the Company expected to recognize the investment under the equity method. As the primary beneficiary of the VIE during the development phase, the Company had consolidated 110 North Wacker and its underlying entities since the second quarter of 2018. During the third quarter of 2020, 110 North Wacker was completed and placed in service, triggering a reconsideration event. Upon development completion, the Company concluded it is no longer the primary beneficiary and as such, should no longer consolidate the Venture. As there have been no changes to the structure and control of the Partnership with the local developer, the Company will continue to consolidate the Partnership. As of September 30, 2020, the Company derecognized all assets, liabilities and noncontrolling interest related to the Venture that were previously consolidated and recognized an equity method investment of $273.6 million based on the fair value of its interest in 110 North Wacker. The Company recognized a gain of $267.5 million attributable to the initial fair value step-up at the time of deconsolidation, which is included in Equity in earnings (losses) from real estate and other affiliates on the Condensed Consolidated Statements of Operations and reported in the Strategic Developments segment for the three months ended September 30, 2020. The Company utilized a third-party appraiser to measure the fair value of 110 North Wacker on an as-is basis at September 30, 2020, using the discounted cash flow approach and sales comparison approach, based on current market assumptions. Also as a result of the deconsolidation, the Company recognized an additional $15.4 million attributable to the recognition of previously eliminated development management fees, which is included in Other land, rental and property revenues on the Condensed Consolidated Statements of Operations and reported in the Strategic Developments segment for the three months ended September 30, 2020. As 110 North Wacker was placed in service, the equity method investment was transferred from the Strategic Development segment to the Operating Asset segment. Given the nature of the Venture’s capital structure and the provisions for the liquidation of assets, the Company’s share of the Venture’s income-producing activities will be recognized based on the Hypothetical Liquidation at Book Value (HLBV) method. Under this method, the Company will recognize income or loss in Equity in earnings from real estate and other affiliates based on the change in its underlying share of the Venture’s net assets on a hypothetical liquidation basis as of the reporting date. After USAA receives a 9.0% preferred return on its capital contribution, the Partnership is entitled to cash distributions from the venture until it receives a 9.0% return on its capital account, calculated as the initial land contribution of $85.0 million and cash contribution of $5.0 million, plus subsequent cash contributions and less subsequent cash distributions. Subsequently, USAA is entitled to cash distributions equal to 11.11% of the amount distributed to the Partnership that resulted in a 9.0% return. Thereafter, the Partnership and USAA are entitled to distributions pari passu to their profit ownership interests of 90% and 10%, respectively. The Lawn Club On January 19, 2021, the Company formed HHC Lawn Games, LLC with The Lawn Club NYC, LLC (Endorphin Ventures), to construct and operate an immersive indoor and outdoor restaurant that includes an extensive area of indoor grass, a stylish clubhouse bar and a wide variety of lawn games. This concept is expected to open in early 2022. Under the terms of the agreement, the Company will fund 80.0% of the cost to construct the restaurant, and Endorphin Ventures will contribute the remaining 20.0%. The Company also entered into a lease agreement with HHC Lawn Games, LLC (Lease Agreement) to lease 20,000 square feet of the Fulton Market Building for this venture. The Company will report its ownership interest in accordance with the equity method. Available cash will be distributed 80.0% to the Company and 20.0% to Endorphin Ventures until each member’s unreturned capital account has been reduced to zero. Distributions will then be allocated 60.0% to the Company and 40.0% to Endorphin Ventures until the amounts paid to the Company under the Lease Agreement and the aggregate amounts distributed to the Company equal $100 per square foot of the property on an annual basis. Any remaining cash will be distributed equally between both members. Given the nature of The Lawn Club’s capital structure and the provisions for the liquidation of assets, the Company’s share of The Lawn Club’s income-producing activities will be recognized based on the HLBV method. Ssäm Bar (formerly Bar Wayō) During the first quarter of 2016, the Company formed Pier 17 Restaurant C101, LLC (Bar Wayō) with MomoPier, LLC (Momofuku), an affiliate of the Momofuku restaurant group, to construct and operate a restaurant and bar at Pier 17 in the Seaport. Under the terms of the agreement, the Company funded 89.75% of the costs to construct the restaurant, and Momofuku contributed the remaining 10.25%. In 2021, Bar Wayō was rebranded as the Ssäm Bar. As of September 30, 2021, and December 31, 2020, Ssäm Bar is classified as a VIE because the equity holders, as a group, lack the characteristics of a controlling financial interest. The carrying value of Ssäm Bar as of September 30, 2021, is $6.1 million and is classified as Investments in real estate and other affiliates in the Condensed Consolidated Balance Sheets. The Company’s maximum exposure to loss as a result of this investment is limited to the aggregate carrying value of the investment as the Company has not provided any guarantees or otherwise made firm commitments to fund amounts on behalf of this VIE. After each member receives a 10.0% preferred return on its capital contributions, available cash will be allocated 75.0% to the Company and 25.0% to Momofuku, until each member’s unreturned capital account has been reduced to zero. Any remaining cash will be distributed to the members in proportion to their respective percentage interests, or 50.0% each to the Company and Momofuku. Given the nature of Ssäm Bar’s capital structure and the provisions for the liquidation of assets, the Company’s share of Ssäm Bar’s income-producing activities is recognized based on the HLBV method. The Summit During the first quarter of 2015, the Company formed DLV/HHPI Summerlin, LLC (The Summit) with Discovery Land Company (Discovery). The Company contributed land with a carrying value of $13.4 million and transferred SID bonds related to such land with a carrying value of $1.3 million to The Summit at the agreed upon capital contribution value of $125.4 million, or $226,000 per acre and has no further capital obligations. Discovery is required to fund up to a maximum of $30.0 million of cash as their capital contribution, of which $3.75 million has been contributed. The gains on the contributed land are recognized in Equity in earnings from real estate and other affiliates as The Summit sells lots. As of September 30, 2021, the Company had received cash distributions equal to its capital contribution of $125.4 million and a 5.0% preferred return on such capital contribution, and Discovery had received cash distributions equal to two times its equity contribution. Any further cash distributions and income-producing activities will be recognized according to equity ownership, with HHC receiving 50.0% and Discovery receiving 50.0%. Summarized Financial Information Relevant financial statement information for significant equity method investments is summarized as follows: thousands The Summit (a)(b) 110 North Wacker (c)(d) Balance Sheet September 30, 2021 Total assets $ 226,600 $ 677,419 Total liabilities 175,960 484,721 Total equity 50,640 192,698 December 31, 2020 Total assets $ 310,855 $ 634,274 Total liabilities 209,968 415,452 Total equity 100,887 218,822 Income Statement Nine Months Ended September 30, 2021 Revenues $ 260,398 $ 22,279 Gross margin 87,837 — Operating income (loss) — 13,811 Net income (loss) 85,925 (32,597) Nine Months Ended September 30, 2020 Revenues $ 96,022 $ — Gross margin 10,501 — Net income (loss) 6,028 — (a) The decrease in Total Equity for The Summit is primarily the result of distributions made in the second quarter of 2021.

Discontinued Operations and Disposal Groups [Abstract]
Dispositions	3. Dispositions On September 16, 2021, the Company completed the sale of The Woodlands Resort, The Westin at The Woodlands and Embassy Suites at Hughes Landing for $252.0 million. These hospitality properties, located in The Woodlands, contained a total of 909 rooms. The carrying value of the properties was approximately $210.0 million at the time of sale. Gain on sale of $39.1 million is calculated as the difference between the sale price and the asset’s carrying value, less related transaction costs of approximately $2.9 million. The gain on sale is included in Gain (loss) on sale or disposal of real estate and other assets, net in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2021. Additionally, as part of the sale, the Company repaid $132.3 million of debt directly associated with the properties sold. Income (loss) before taxes for these properties consisted of losses of $1.2 million for the three months ended September 30, 2021, $3.1 million for the three months ended September 30, 2020, $6.3 million for the nine months ended September 30, 2021, and $8.4 million for the nine months ended September 30, 2020. On May 7, 2021, the Company completed the sale of Monarch City, a property comprised of approximately 229 acres of undeveloped land in Collin County, Texas, for $51.4 million. The carrying value of the property was approximately $28.7 million at the time of sale. Gain on sale of $21.3 million is calculated as the difference between the sale price and the asset’s carrying value, less related transaction costs of approximately $1.5 million. The gain on sale is included in Gain (loss) on sale or disposal of real estate and other assets, net in the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2021. On July 16, 2020, the Company completed the sale of its 35% equity investment in Mr. C Seaport, a 66-room boutique hotel located at 33 Peck Slip, New York, in close proximity to the Seaport District, for $0.8 million. Refer to Note 2 - Real Estate and Other Affiliates and Note 4 - Impairment for additional information. On June 29, 2020, the Company entered into an agreement terminating a participation right contained in the contract for the sale of West Windsor in October 2019. As consideration, the Company received an $8.0 million termination payment in July 2020, which was included in Gain (loss) on sale or disposal of real estate and other assets, net on the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2020. In March 2020, the Company closed on the sale of its property at 100 Fellowship Drive, a 13.5-acre land parcel and 203,257-square-foot build-to-suit medical building with approximately 550 surface parking spaces in The Woodlands, Texas, for a total sales price of $115.0 million. The Company had previously entered into a lease agreement related to this property in November of 2019, and at lease commencement, the Company derecognized $63.7 million from Developments and recorded an initial net investment in lease receivable of $75.9 million on the Condensed Consolidated Balance Sheets, recognizing $13.5 million of Selling profit from the sales-type lease on the Condensed Consolidated Statements of Operations. The sale of 100 Fellowship Drive resulted in an additional gain of $38.3 million in the first quarter of 2020, which was included in Gain (loss) on sale or disposal of real estate and other assets, net on the Condensed Consolidated Statements of Operations. The carrying value of the net investment in lease receivable was approximately $76.1 million at the time of sale. Gain on sale is calculated as the difference between the sale price of $115.0 million, and the asset’s carrying value, less related transaction costs of approximately $0.2 million. Contemporaneous with the sale, the Company credited to the buyer approximately $0.6 million for operating account funds and the buyer’s assumption of the related liabilities. After the sale, the Company had no continuing involvement in this lease. After repayment of debt associated with the property, the sale generated approximately $64.2 million in net proceeds, which are presented as cash inflows from operating activities in the Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020.

Impairment

Property, Plant and Equipment [Abstract]
Impairment	4. Impairment The Company reviews its long-lived assets for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. During the second quarter of 2021, the Company recorded a $13.1 million impairment charge for Century Park, which is included in Provision for impairment on the Condensed Consolidated Statements of Operations. The Century Park asset includes both building and land components. The impairment relates to the building component, while the land component was not impaired. Century Park is a 63-acre, 1.3 million square foot campus with 17 office buildings in the West Houston Energy Corridor, a non-core asset acquired as part of the acquisition of The Woodlands Towers at The Waterway. The Company recognized an impairment due to decreases in estimated future cash flows and as a result of the impact of a shorter than anticipated holding term. The Company used weighted market and income valuation techniques to estimate the fair value of Century Park. Market valuation was based on recent sales of similar commercial properties in and around Houston, Texas. For the income approach, the Company utilized a capitalization rate of 8.75%, and probability weighted scenarios assuming lease-up periods ranging from 24 months to 48 months, and management’s estimate of future lease income and carry costs. During the first quarter of 2020, the Company recorded a $48.7 million impairment charge for Outlet Collection at Riverwalk, which is included in Provision for impairment on the Condensed Consolidated Statements of Operations. The Outlet Collection at Riverwalk is a 273,270-square-foot urban upscale outlet center located along the Mississippi River in downtown New Orleans, Louisiana. The Company recognized the impairment due to decreases in estimated future cash flows as a result of the impact of a shorter than anticipated holding term due to management’s plans to divest the non-core operating asset, decreased demand and reduced interest in brick and mortar retail due to the impact of COVID-19, as well as an increase in the capitalization rate used to evaluate future cash flows due to the impact of COVID-19. The $46.8 million net carrying value of Outlet Collection at Riverwalk, after the impairment, represents the estimated fair market value at March 31, 2020, at the time of the impairment assessment. The Company used a discounted cash flow analysis using a capitalization rate of 10% to determine fair value. There can be no assurance that the Company will ultimately recover the fair value amounts of Century Park or Outlet Collection at Riverwalk through sales of these assets. Refer to Note 7 - Fair Value for additional information. Each investment in real estate and other affiliates discussed in Note 2 - Real Estate and Other Affiliates is evaluated periodically for recoverability and valuation declines that are other-than-temporary. If the decrease in value of an investment in a real estate and other affiliate is deemed to be other-than-temporary, the investment in such real estate and other affiliates is reduced to its estimated fair value. No impairment charges were recorded for Investment in real estate and other affiliates during the three and nine months ended September 30, 2021. During the three months ended June 30, 2020, the Company recorded a $6.0 million impairment of its equity investment in Mr. C Seaport, a 66-room boutique hotel located at 33 Peck Slip in close proximity to the Seaport District. The Company recognized the impairment due to a change in the anticipated holding period as the Company entered into a plan to sell its 35% equity investment in Mr. C Seaport to its venture partners for $0.8 million. The Company completed the sale of its interest in Mr. C Seaport in July 2020. The impairment loss is presented in Equity in (losses) earnings from real estate and other affiliates. Refer to Note 2 - Real Estate and Other Affiliates for additional information. The Company periodically evaluates its strategic alternatives with respect to each property and may revise the strategy from time to time, including the intent to hold the asset on a long-term basis or the timing of potential asset dispositions. For example, the Company may decide to sell property that is held for use, which may result in impairment charges if the current fair value of the property does not support the carrying amount. As a result, changes in strategy could result in impairment charges in future periods. In addition to the impairments discussed above, during 2020, the Company reduced the estimated net sales price of certain condominium units, including the remaining penthouse inventory, to better align the expected price with recent final sales prices, resulting in a loss of $6.0 million included in Condominium rights and unit cost of sales.

Other Assets and Liabilities Prepaid Expenses and Other Assets The following table summarizes the significant components of Prepaid expenses and other assets: thousands September 30, 2021 December 31, 2020 $ Change Special Improvement District receivable (a) $ 89,677 $ 54,770 $ 34,907 Security, escrow and other deposits (b) 45,425 48,576 (3,151) In-place leases 45,400 49,161 (3,761) Intangibles 30,571 32,595 (2,024) Prepaid expenses (c) 28,597 17,455 11,142 Condominium inventory (d) 18,473 55,883 (37,410) Tenant incentives and other receivables 7,115 9,612 (2,497) Other 7,053 12,096 (5,043) Food and beverage and lifestyle inventory 1,035 1,060 (25) TIF receivable 751 893 (142) Prepaid expenses and other assets, net $ 274,097 $ 282,101 $ (8,004) (a) The increase in Special Improvement District receivable is primarily attributable to a third quarter 2021 SID Bond issuance in Summerlin. Proceeds from SID bonds are held in escrow by a third party and are used to reimburse the Company for a portion of the development costs. (b) The decrease in Security, escrow and other deposits is primarily attributable to a $29.5 million settlement of the rate-lock agreement associated with the loans for 1201 Lake Robbins and The Woodlands Warehouse upon repayment in February 2021, partially offset by a $27.5 million deposit related to the loan for Bridgeland entered into in September 2021. (c) The increase in Prepaid expenses is mainly due to the timing of insurance and property tax prepayments. (d) The decrease in Condominium inventory is attributable to closing on inventory units at Waiea and Anaha. Accounts Payable and Accrued Expenses The following table summarizes the significant components of Accounts payable and accrued expenses: thousands September 30, 2021 December 31, 2020 $ Change Condominium deposit liabilities (a) $ 550,619 $ 309,884 $ 240,735 Construction payables (b) 312,767 253,626 59,141 Deferred income 63,157 66,656 (3,499) Tenant and other deposits (c) 38,016 25,801 12,215 Accounts payable and accrued expenses 36,961 28,589 8,372 Accrued real estate taxes 35,748 38,863 (3,115) Interest rate swap liabilities (d) 35,367 51,920 (16,553) Accrued payroll and other employee liabilities 25,794 27,419 (1,625) Accrued interest (e) 22,972 37,007 (14,035) Other 20,360 12,493 7,867 Accounts payable and accrued expenses $ 1,141,761 $ 852,258 $ 289,503 (a) The increase in Condominium deposit liabilities is attributable to contracted sales at ‘A‘ali‘i, The Park Ward Village, Victoria Place and Kō'ula. (b) The increase in Construction payables is attributable to an increase of $119.4 million primarily related to increased construction spend at Ward Village, the Summerlin and Bridgeland MPC developments and the Tin Building, as well as a $21.0 million charge for additional remediation costs at Waiea. These increases are partially offset by decreases of $60.3 million related to a reduction of construction spend for projects placed in service in 2020 or approaching completion, as well as costs incurred and paid for Waiea remediation activities during 2021. (c) The increase in Tenant and other deposits is primarily due to a $13.5 million deposit received in the second quarter of 2021 related to a 216-acre superpad sale in Summerlin. The sale is expected to close in the fourth quarter of 2021. (d) The decrease in Interest rate swap liabilities is due to an increase of the one-month London Interbank Offered Rate (LIBOR) forward curve for the periods presented. (e) The decrease in Accrued interest is primarily due to the repurchase of the $1.0 billion 5.375% Senior Notes due 2025, partially offset by the issuance of $650 million in 4.125% Senior Notes due 2029 and $650 million in 4.375% Senior Notes due 2031, in the first quarter of 2021.

See Note 8 - Derivative Instruments and Hedging Activities for additional information. (b) Deferred financing costs are amortized to interest expense over the terms of the respective financing agreements using the effective interest method (or other methods which approximate the effective interest method). Debt Collateral Certain of the Company’s loans contain provisions which grant the lender a security interest in the operating cash flow of the property that represents the collateral for the loan. Certain mortgage notes may be prepaid subject to a prepayment penalty equal to a yield maintenance premium, defeasance or percentage of the loan balance. As of September 30, 2021, land, buildings and equipment and developments with a net book value of $4.2 billion have been pledged as collateral for HHC’s mortgages, notes and loans payable. Credit Facilities In 2018, the Company entered into a $700.0 million loan agreement, which provided for a $615.0 million term loan (the Term Loan) and an $85.0 million revolver loan (the Revolver Loan and together with the Term Loan, the Senior Secured Credit Facility). Concurrent with the sale of The Westin at The Woodlands and Embassy Suites at Hughes Landing in September 2021, $181.8 million was repaid on the Term Loan, of which $69.8 million was directly associated with the properties sold. Refer to Note 3 - Dispositions for additional information. As of September 30, 2021, the Company had $433.2 million of outstanding borrowings on the Term Loan. The Company has a one-time right to request an increase of $50.0 million in the aggregate amount of the Revolver Loan commitment. As of September 30, 2021, the Company had no outstanding borrowings under the Revolver Loan. In 2019, the Company closed on a $250.0 million credit facility secured by MUD receivables, land and certain other collateral in both The Woodlands and Bridgeland MPCs. The loan provided for a $100.0 million term loan and a $150.0 million revolver loan. In September 2021, the Company repaid the $100.0 million term loan and the $50.0 million outstanding borrowings under the revolver portion of the loan. As a result, the Company no longer has access to the $150.0 million revolver loan. These borrowings were replaced by a $275.0 million loan for Bridgeland. See the table below for additional detail. Special Improvement District Bonds The Summerlin MPC uses SID bonds to finance certain common infrastructure improvements. These bonds are issued by the municipalities and are secured by the assessments on the land. The majority of proceeds from each bond issued is held in a construction escrow and disbursed to the Company as infrastructure projects are completed, inspected by the municipalities and approved for reimbursement. Accordingly, the SID bonds have been classified as debt, and the Summerlin MPC pays the debt service on the bonds semi‑annually. As Summerlin sells land, the buyers assume a proportionate share of the bond obligation at closing, and the residential sales contracts provide for the reimbursement of the principal amounts that the Company previously paid with respect to such proportionate share of the bond. In the nine months ended September 30, 2021, $45.4 million in SID bonds were issued and obligations of $8.5 million were assumed by buyers. Debt Compliance Due to the COVID-19 pandemic, the Company experienced a decline in operating results for certain retail and hospitality properties. As a result, as of December 31, 2020, the Company did not meet the debt service coverage ratio for the $615.0 million Term Loan portion of the Senior Secured Credit Facility and as a result, the excess net cash flow after debt service from the underlying properties became restricted. As a result of the $181.8 million payment on the Term Loan in the third quarter, the Company met the debt service coverage ratio as of September 30, 2021. However, two consecutive quarters of compliance are required to release the restricted cash requirement, and $58.8 million of cash was restricted as of September 30, 2021. While the restricted cash cannot be used for general corporate purposes, it can continue to be used to fund operations of the underlying assets, and during the third quarter of 2021, the Company submitted reimbursement for $33.1 million related to operating expenses. This does not have a material impact on the Company’s liquidity. As of September 30, 2021, the Company was in compliance with all financial covenants included in the agreements governing its indebtedness.

In certain cases, due to property performance not meeting covenants, HHC may have to pay down a portion of the loan to obtain the extension. (b) The interest rate presented is based on the one-month LIBOR, three-month LIBOR or Prime rate, as applicable, which was 0.10%, 0.15% and 3.25%, respectively, at September 30, 2021. Interest rates associated with loans that have been paid off reflect the interest rate at December 31, 2020.

Fair Value Disclosures [Abstract]
Fair Value	7. Fair Value ASC 820, Fair Value Measurement , emphasizes that fair value is a market-based measurement that should be determined using assumptions market participants would use in pricing an asset or liability. The standard establishes a hierarchical disclosure framework that prioritizes and ranks the level of market price observability used in measuring assets or liabilities at fair value. Market price observability is impacted by a number of factors, including the type of investment and the characteristics specific to the asset or liability. Assets or liabilities with readily available active quoted prices, or for which fair value can be measured from actively quoted prices, generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. The following table presents the fair value measurement hierarchy levels required under ASC 820 for the Company’s liabilities that are measured at fair value on a recurring basis: September 30, 2021 December 31, 2020 Fair Value Measurements Using Fair Value Measurements Using thousands Total Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Total Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: Interest rate derivative assets $ 114 $ — $ 114 $ — $ — $ — $ — $ — Liabilities: Interest rate derivative liabilities $ 35,367 $ — $ 35,367 $ — $ 51,920 $ — $ 51,920 $ — The fair values of interest rate derivatives are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates derived from observable market interest rate curves. The estimated fair values of the Company’s financial instruments that are not measured at fair value on a recurring basis are as follows: September 30, 2021 December 31, 2020 thousands Fair Value Hierarchy Carrying Amount Estimated Fair Value Carrying Amount Estimated Fair Value Assets: Cash and Restricted cash Level 1 $ 1,448,569 $ 1,448,569 $ 1,242,997 $ 1,242,997 Accounts receivable, net (a) Level 3 81,935 81,935 66,726 66,726 Notes receivable, net (b) Level 3 5,536 5,536 622 622 Liabilities: Fixed-rate debt (c) Level 2 2,795,832 2,838,696 2,374,822 2,461,155 Variable-rate debt (c) Level 2 1,672,881 1,672,881 1,945,344 1,945,344 (a) Accounts receivable, net is shown net of an allowance of $29.9 million at September 30, 2021, and $33.0 million at December 31, 2020.

The carrying amounts of Cash and Restricted cash, Accounts receivable, net and Notes receivable, net approximate fair value because of the short‑term maturity of these instruments. The fair value of the Company’s Senior Notes, included in fixed-rate debt in the table above, is based upon the trade price closest to the end of the period presented. The fair value of other fixed-rate debt in the table above was estimated based on a discounted future cash payment model, which includes risk premiums and risk-free rates derived from the current LIBOR or U.S. Treasury obligation interest rates.

The discount rates reflect the Company’s judgment as to what the approximate current lending rates for loans or groups of loans with similar maturities and credit quality would be if credit markets were operating efficiently and assuming that the debt is outstanding through maturity. The carrying amounts for the Company’s variable-rate debt approximate fair value given that the interest rates are variable and adjust with current market rates for instruments with similar risks and maturities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	8. Derivative Instruments and Hedging Activities The Company is exposed to interest rate risk related to its variable interest rate debt, and it manages this risk by utilizing interest rate derivatives. The Company uses interest rate swaps and caps to add stability to interest costs by reducing the Company’s exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company’s fixed‑rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up‑front premium. The Company’s interest rate caps are not currently designated as hedges, and therefore, any gains or losses are recognized in current-period earnings. These derivatives are recorded on a gross basis at fair value on the balance sheet. Assessments of hedge effectiveness are performed quarterly using regression analysis. The change in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in Accumulated Other Comprehensive Income (AOCI) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings within the same income statement line item being hedged. Derivatives accounted for as cash flow hedges are classified in the same category in the Condensed Consolidated Statements of Cash Flows as the items being hedged. Gains and losses from derivative financial instruments are reported in Cash (used in) provided by operating activities within the Condensed Consolidated Statements of Cash Flows. The Company is exposed to credit risk in the event of non-performance by its derivative counterparties. The Company evaluates counterparty credit risk through monitoring the creditworthiness of counterparties, which includes review of debt ratings and financial performance. To mitigate its credit risk, the Company enters into agreements with counterparties that are considered creditworthy, such as large financial institutions with favorable credit ratings. There were no events of default as of September 30, 2021, or as of December 31, 2020. If the derivative contracts are terminated prior to their maturity, the amounts previously recorded in AOCI are recognized into earnings over the period that the hedged transaction impacts earnings. If the hedging relationship is discontinued because it is probable that the forecasted transaction will not occur in accordance with the original strategy, any related amounts previously recorded in AOCI are recognized in earnings immediately. During the nine months ended September 30, 2021, and the year ended December 31, 2020, there were no termination events. The Company recorded a $0.7 million reduction in Interest expense during the three months ended September 30, 2021, and a $2.2 million reduction in Interest expense during the nine months ended September 30, 2021, related to the amortization of terminated swaps. The Company did not settle any derivatives during the nine months ended September 30, 2021, or the year ended December 31, 2020. Amounts reported in AOCI related to derivatives will be reclassified to Interest expense as interest payments are made on the Company’s variable‑rate debt. Over the next 12 months, the Company estimates that an additional $17.3 million of net loss will be reclassified to Interest expense. The following table summarizes certain terms of the Company’s derivative contracts: Fair Value Asset (Liability) thousands Balance Sheet Location Notional Amount Fixed Interest Rate (a) Effective Date Maturity Date September 30, 2021 December 31, 2020 Derivative instruments not designated as hedging instruments: Interest rate cap (b) Prepaid expenses and other assets, net $ 285,000 2.00 % 3/12/2021 9/15/2023 $ 88 $ — Interest rate cap (b) Prepaid expenses and other assets, net 83,200 2.00 % 3/12/2021 9/15/2023 26 — Interest rate cap (c) Prepaid expenses and other assets, net 75,000 5.00 % 8/31/2020 10/17/2022 — — Total fair value derivative assets $ 114 $ — Derivative instruments designated as hedging instruments: Interest rate swap (d) Accounts payable and accrued expenses $ 615,000 2.96 % 9/21/2018 9/18/2023 $ (32,110) $ (46,613) Interest rate swap (e) Accounts payable and accrued expenses 35,485 4.89 % 11/1/2019 1/1/2032 (3,257) (5,307) Total fair value derivative liabilities (35,367) (51,920) Total fair value derivatives, net $ (35,253) $ (51,920) (a) These rates represent the strike rate on HHC’s interest swaps and caps. (b) In March 2021, the Company entered into two new LIBOR interest rate caps, which are not designated as hedging instruments. Interest expense included in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2021, related to these contracts was not material. (c) In the third quarter of 2020, the Company executed an agreement to extend the maturing position of this LIBOR cap. Interest expense included in the Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2021, and the year ended December 31, 2020, related to this contract was not material. (d) Concurrent with the funding of the $615.0 million Term Loan in September 2018, the Company entered into this interest rate swap which is designated as a cash flow hedge. In conjunction with the sale of The Westin at The Woodlands and Embassy Suites at Hughes Landing in September 2021, $181.8 million was repaid on the Term Loan. This swap covers the outstanding balance on the Term Loan in addition to other LIBOR-based debt held by the Company. (e) Concurrent with the closing of the $35.5 million construction loan for 8770 New Trails in June 2019, the Company entered into this interest rate swap, which is designated as a cash flow hedge.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies In the normal course of business, from time to time, the Company is involved in legal proceedings relating to the ownership and operations of its properties. In management’s opinion, the liabilities, if any, that may ultimately result from normal course of business legal actions, including The Woodlands legal proceeding discussed below , are not expected to have a material effect on the Company’s consolidated financial position, results of operations or liquidity. Litigation On June 14, 2018, the Company was served with a petition involving approximately 500 individuals or entities who claim that their properties, located in the Timarron Park neighborhood of The Woodlands, were damaged by flood waters that resulted from the unprecedented rainfall that occurred throughout Harris County and surrounding areas during Hurricane Harvey in August 2017. The complaint was filed in State Court in Harris County of the State of Texas. In general, the plaintiffs allege negligence in the development of Timarron Park and violations of Texas’ Deceptive Trade Practices Act and name as defendants The Howard Hughes Corporation, The Woodlands Land Development Company and two unaffiliated parties involved in the planning and engineering of Timarron Park. The plaintiffs are seeking restitution for damages to their property and diminution of their property values. The Company intends to vigorously defend the matter as it believes that these claims are without merit and that it has substantial legal and factual defenses to the claims and allegations contained in the complaint. Based upon the present status of this matter, the Company does not believe it is probable that a loss will be incurred. Accordingly, the Company has not recorded a charge as a result of this action. The Company entered into a settlement agreement with the Waiea homeowners association related to certain construction defects at the tower. Pursuant to the settlement agreement, the Company will pay for the repair of the defects. The Company believes that the general contractor is ultimately responsible for the defects and expects to recover all the repair costs from the general contractor, other responsible parties and insurance proceeds; however, the Company can provide no assurances that all or any portion of these costs will be recovered. The Company recorded total expenses of $99.2 million for the estimated repair costs related to this matter during 2020. An additional $21.0 million was charged during the nine months ended September 30, 2021, related to additional anticipated costs. These amounts were included in Condominium rights and unit cost of sales in the accompanying Condensed Consolidated Statements of Operations. As of September 30, 2021, a total of $101.9 million remains in Construction payables for the estimated repair costs related to this matter, which is included in Accounts payable and accrued expenses in the accompanying Condensed Consolidated Balance Sheet. Environmental Matters The Company purchased its 250 Water Street property in the Seaport in June 2018. The site is currently used as a parking lot while the Company continues to move forward with redevelopment planning. The Company engaged a third-party specialist to perform a Phase I Environmental Site Assessment (ESA), and the ESA identified, among other findings, the existence of mercury in the soil at levels above New York State regulatory criteria. The site is in the State Brownfield Cleanup Program and is proposed to be remediated under this program. The normal operations of the parking lot do not require the property to be remediated, and the Company has not started any redevelopment activities as of September 30, 2021. As a result, the potential remediation has no financial impact for the three and nine months ended September 30, 2021. Letters of Credit and Surety Bonds As of September 30, 2021, the Company had outstanding letters of credit totaling $5.1 million and surety bonds totaling $357.3 million. As of December 31, 2020, the Company had outstanding letters of credit totaling $5.2 million and surety bonds totaling $272.4 million. These letters of credit and surety bonds were issued primarily in connection with insurance requirements, special real estate assessments and construction obligations. Operating Leases The Company leases land or buildings at certain properties from third parties, which are recorded in Operating lease right-of-use assets, net and Operating lease obligations on the Condensed Consolidated Balance Sheets. See Note 15 - Leases for further discussion. Contractual rental expense, including participation rent, was $1.9 million for the three months ended September 30, 2021, and $5.5 million for the nine months ended September 30, 2021, compared to $2.0 million for the three months ended September 30, 2020, and $5.3 million for the nine months ended September 30, 2020. The amortization of above and below‑market ground leases and straight‑line rents included in the contractual rent amount was not significant. Guarantee Agreements In conjunction with the execution of the ground lease for the Seaport, the Company executed a completion guarantee for the redevelopment of the Tin Building. The completion guaranty is for the core and shell construction, which is nearing completion. The Company’s wholly owned subsidiaries agreed to complete defined public improvements and to indemnify Howard County, Maryland, for certain matters as part of the Downtown Columbia Redevelopment District TIF bonds. To the extent that increases in taxes do not cover debt service payments on the TIF bonds, the Company’s wholly owned subsidiary is obligated to pay special taxes. Management has concluded that as of September 30, 2021, any obligations to pay special taxes are not probable. As part of the Company’s development permits with the Hawai’i Community Development Authority for the condominium towers at Ward Village, the Company is required to reserve 20% of the residential units for local residents who meet certain maximum income and net worth requirements. This requirement, which is triggered once the necessary permits are granted and construction commences, was satisfied for the Company’s three condominium towers, Waiea, Anaha and Ae‘o, with the opening of the Company’s fourth tower, Ke Kilohana, which is a workforce tower fully earmarked to fulfill this obligation. For the three towers under construction, the reserved units for the ‘A‘ali‘i tower are included in the tower, and the units for Kō'ula and Victoria Place will either be built off site or fulfilled by paying a cash-in-lieu fee. As a result of this guarantee, the Company expects that future reserved housing towers will be delivered on a break-even basis. The Company evaluates the likelihood of future performance under these guarantees and did not record an obligation as of September 30, 2021, and December 31, 2020.

The Company’s effective tax rate is typically impacted by non-deductible executive compensation and other permanent differences as well as state income taxes, which cause the Company’s effective tax rate to deviate from the federal statutory rate. For the three and nine months ended September 30, 2021, the effective rate was also impacted by the release of a valuation allowance on the Company’s capital loss carryover. For the three and nine months ended September 30, 2020, the effective rate was also impacted by the gain on the deconsolidation of 110 North Wacker (refer to Note 2 - Real Estate and Other Affiliates for additional details), a tax expense related to the recapture of federal and state historic preservation credits due to the sale of HHC’s interest in Mr. C Seaport (refer to Note 3 - Dispositions for additional details) and a valuation allowance on the Company’s carryover for charitable contributions.

Earnings Per Share [Abstract]
Earnings Per Share	13. Earnings Per Share Basic earnings per share (EPS) is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted EPS is computed after adjusting the numerator and denominator of the basic EPS computation for the effects of all potentially dilutive common shares. The dilutive effect of options and non-vested stock issued under stock-based compensation plans is computed using the treasury stock method. The dilutive effect of the warrants is computed using the if-converted method.

For the nine months ended September 30, 2021, the diluted EPS computation excludes 286,487 shares of stock options and 465,574 shares of restricted stock because their effect is anti-dilutive. For the three months ended September 30, 2020, the diluted EPS computation excludes 391,875 shares of stock options and 363,683 shares of restricted stock because their effect is anti-dilutive. For the nine months ended September 30, 2020, the diluted EPS computation excludes 398,650 shares of stock options and 428,172 shares of restricted stock because their effect is anti-dilutive. Common Stock Offering On March 27, 2020, the Company offered 2,000,000 shares of common stock to the public at $50.00 per share and granted the underwriters an option to purchase up to an additional 300,000 shares of common stock at the same price. The underwriters exercised most of their option and purchased an additional 270,900 shares. Concurrently, the Company entered into a share purchase agreement with a related party, Pershing Square Capital Management, L.P., acting as investment advisor to funds that it manages, to issue and sell 10,000,000 shares of common stock in a private placement at $50.00 per share. The total issuance of 12,270,900 shares closed on March 31, 2020, and the Company received $593.6 million in net proceeds. The Company used the net proceeds for general corporate purposes including strengthening the Company’s balance sheet and enhancing liquidity.

Revenue from Contract with Customer [Abstract]
Revenues	14. Revenues Revenues from contracts with customers (excluding lease-related revenues) are recognized when control of the promised goods or services is transferred to the Company’s customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Revenue and cost of sales for condominium units sold are not recognized until the construction is complete, the sale closes and the title to the property has transferred to the buyer (point in time). Additionally, certain real estate selling costs, such as the costs related to the Company’s condominium model units, are either expensed immediately or capitalized as property and equipment and depreciated over their estimated useful life.

Contract liabilities are the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration. There were no contract assets for the period. The contract liabilities primarily relate to escrowed condominium deposits, MPC land sales deposits and deferred MPC land sales related to unsatisfied land improvements. The beginning and ending balances of contract liabilities and significant activity during the period are as follows: thousands Contract Liabilities Balance as of December 31, 2020 $ 360,416 Consideration earned during the period (95,847) Consideration received during the period 351,677 Balance as of September 30, 2021 $ 616,246 Balance as of December 31, 2019 $ 246,010 Consideration earned during the period (38,960) Consideration received during the period 138,291 Balance as of September 30, 2020 $ 345,341 Remaining Unsatisfied Performance Obligations The Company’s remaining unsatisfied performance obligations as of September 30, 2021, represent a measure of the total dollar value of work to be performed on contracts executed and in progress. These performance obligations primarily relate to the completion of condominium construction and transfer of control to a buyer, as well as the completion of contracted MPC land sales and related land improvements. These obligations are associated with contracts that generally are noncancelable by the customer after 30 days; however, purchasers of condominium units have the right to cancel the contract should the Company elect not to construct the condominium unit within a certain period of time or materially change the design of the condominium unit. The aggregate amount of the transaction price allocated to the Company’s remaining unsatisfied performance obligations as of September 30, 2021, is $2.4 billion. The Company expects to recognize this amount as revenue over the following periods: thousands Less than 1 year 1-2 years 3 years and thereafter Total remaining unsatisfied performance obligations $ 1,314,945 $ 21,221 $ 1,093,345

Leases [Abstract]
Leases	15. Leases Lessee Arrangements The Company determines whether an arrangement is a lease at inception. Operating leases are included in Operating lease right-of-use assets, net and Operating lease obligations on the Condensed Consolidated Balance Sheets. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of future minimum lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses an estimate of the incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. The Operating lease right-of-use asset also includes any lease payments made, less any lease incentives and initial direct costs incurred.

Percentage rent in lieu of fixed minimum rent is recognized as sales are reported from tenants. Minimum rent revenues reported on the Condensed Consolidated Statements of Operations also include amortization related to above and below‑market tenant leases on acquired properties. In response to the COVID-19 pandemic, the Company granted rent deferrals to certain tenants. Under the accounting elections provided by the Financial Accounting Standards Board (FASB) in response to the COVID-19 pandemic, the Company has elected to not assess whether COVID-19 related deferrals are lease modifications and will account for the deferrals as if contemplated in the original lease. Rent deferrals are treated as variable lease payments resulting in a decrease in straight-line rent revenue during the deferral period and additional revenue upon payment in subsequent periods. COVID-19 related rent deferrals, net of subsequent collections was $4.8 million as of December 31, 2020 and $2.4 million as of September 30, 2021. In 2020, the Company sold 100 Fellowship Drive, one of its sales-type leases.

Segment Reporting [Abstract]
Segments	16. Segments The Company has four business segments that offer different products and services. HHC’s four segments are managed separately because each requires different operating strategies or management expertise and are reflective of management’s operating philosophies and methods. As further discussed in Item 2. - Management’s Discussion and Analysis of Financial Condition and Results of Operations , one common operating measure used to assess operating results for the Company’s business segments is earnings before taxes (EBT). The Company’s segments or assets within such segments could change in the future as development of certain properties commences or other operational or management changes occur. All operations are within the United States. The Company’s reportable segments are as follows: – Operating Assets – consists of developed or acquired retail, office and multi-family properties along with other real estate investments. These properties are currently generating revenues and may be redeveloped, repositioned, or sold to improve segment performance or to recycle capital. This segment also included hospitality properties prior to the sale of The Woodlands Resort, The Westin at The Woodlands and Embassy Suites at Hughes Landing in the third quarter of 2021. Refer to Note 3 - Dispositions for additional information. – MPC – consists of the development and sale of land in large‑scale, long‑term community development projects in and around Las Vegas, Nevada; Houston, Texas; and Columbia, Maryland. – Seaport – consists of approximately 453,000 square feet of restaurant, retail and entertainment properties situated in three primary locations in New York, New York: Pier 17, Historic Area/Uplands and Tin Building as well as the 250 Water Street parking lot. While the Tin Building is still under development and will comprise about 53,000 square feet when completed, the two operating locations consist of third-party tenants, tenants either directly or jointly owned and operated by the Company and businesses owned and operated by the Company under licensing agreements. – Strategic Developments – consists of residential condominium and commercial property projects currently under development and all other properties held for development which have no substantial operations.

Accounting Policies [Abstract]
Restricted Cash	Restricted Cash Restricted cash reflects amounts segregated in escrow accounts in the name of the Company, primarily related to escrowed condominium deposits by buyers and other amounts related to taxes, insurance and legally restricted security deposits and leasing costs.
Accounts Receivable, net	Accounts Receivable, net On a quarterly basis, management reviews tenant rents, tenant recoveries and straight-line rent assets for collectability. As required under Accounting Standards Codification (ASC) 842 - Leases, this analysis includes a review of past due accounts and considers factors such as the credit quality of tenants, current economic conditions and changes in customer payment trends. When full collection of a lease receivable or future lease payment is not probable, a reserve for the receivable balance is charged against rental revenue and future rental revenue is recognized on a cash basis. Due to the continued impacts of COVID-19 on the collectability of tenant receivables, the Company determined full collection of outstanding tenant rents and recoveries was not probable for some retail tenants. In addition, the Company determined that a reserve for estimated losses under ASC 450 - Contingencies is required as the amount is probable and can be reasonably estimated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The estimates and assumptions include, but are not limited to, capitalization of development costs, provision for income taxes, recoverable amounts of receivables and deferred tax assets, initial valuations of tangible and intangible assets acquired and the related useful lives of assets upon which depreciation and amortization is based. Estimates and assumptions have also been made with respect to future revenues and costs, debt and options granted. In particular, Master Planned Communities (MPC) cost of sales estimates are highly judgmental as they are sensitive to cost escalation, sales price escalation and lot absorption, which are subject to judgment and affected by expectations about future market or economic conditions. Actual results could differ from these and other estimates. In addition, these estimates may change in the near term due to the continued demands and constraints on the Company’s supply chain resulting from the COVID-19 pandemic.
Noncontrolling Interests	Noncontrolling Interests As of September 30, 2021 and December 31, 2020, noncontrolling interests are related to the Ward Village Homeowners’ Associations (HOAs). All revenues and expenses related to the HOAs are attributable to noncontrolling interests and do not impact net income attributable to common stockholders. For additional information on redeemable noncontrolling interest refer to Note 2 - Real Estate and Other Affiliates
Financial Instruments - Credit Losses	Financial Instruments - Credit Losses The Company is exposed to credit losses through the sale of goods and services to the Company’s customers. Receivables held by the Company primarily relate to short-term trade receivables and financing receivables, which include Municipal Utility District (MUD) receivables, Special Improvement District (SID) bonds, TIF receivables, net investments in lease receivables, and notes receivable. The Company assesses its exposure to credit loss based on historical collection experience and future expectations by portfolio segment. Historical collection experience is evaluated on a quarterly basis by the Company. The amortized cost basis of financing receivables, consisting primarily of MUD receivables, totaled $482.6 million as of September 30, 2021, including accrued interest of $21.0 million. There has been no material activity in the allowance for credit losses for financing receivables for the nine months ended September 30, 2021. Financing receivables are considered to be past due once they are 30 days contractually past due under the terms of the agreement. The Company does not have significant receivables that are past due or on nonaccrual status. There have been no significant write-offs or recoveries of amounts previously written off during the current period for financing receivables.
Recently Issued Accounting Standards	Recently Issued Accounting Standards The following is a summary of recently issued and other notable accounting pronouncements that relate to the Company’s business. ASU 2020-04, Reference Rate Reform The amendments in this Update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform when certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, for which an entity has applied certain optional expedients that are retained through the end of the hedging relationship. The amendments in this Update are effective as of March 12, 2020, through December 31, 2022. The guidance in Accounting Standards Update (ASU) 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the first quarter of 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedge transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued.

Summary of the significant components of prepaid expenses and other assets	The following table summarizes the significant components of Prepaid expenses and other assets: thousands September 30, 2021 December 31, 2020 $ Change Special Improvement District receivable (a) $ 89,677 $ 54,770 $ 34,907 Security, escrow and other deposits (b) 45,425 48,576 (3,151) In-place leases 45,400 49,161 (3,761) Intangibles 30,571 32,595 (2,024) Prepaid expenses (c) 28,597 17,455 11,142 Condominium inventory (d) 18,473 55,883 (37,410) Tenant incentives and other receivables 7,115 9,612 (2,497) Other 7,053 12,096 (5,043) Food and beverage and lifestyle inventory 1,035 1,060 (25) TIF receivable 751 893 (142) Prepaid expenses and other assets, net $ 274,097 $ 282,101 $ (8,004) (a) The increase in Special Improvement District receivable is primarily attributable to a third quarter 2021 SID Bond issuance in Summerlin. Proceeds from SID bonds are held in escrow by a third party and are used to reimburse the Company for a portion of the development costs. (b) The decrease in Security, escrow and other deposits is primarily attributable to a $29.5 million settlement of the rate-lock agreement associated with the loans for 1201 Lake Robbins and The Woodlands Warehouse upon repayment in February 2021, partially offset by a $27.5 million deposit related to the loan for Bridgeland entered into in September 2021. (c) The increase in Prepaid expenses is mainly due to the timing of insurance and property tax prepayments. (d) The decrease in Condominium inventory is attributable to closing on inventory units at Waiea and Anaha.
Summary of the significant components of accounts payable and accrued expenses	The following table summarizes the significant components of Accounts payable and accrued expenses: thousands September 30, 2021 December 31, 2020 $ Change Condominium deposit liabilities (a) $ 550,619 $ 309,884 $ 240,735 Construction payables (b) 312,767 253,626 59,141 Deferred income 63,157 66,656 (3,499) Tenant and other deposits (c) 38,016 25,801 12,215 Accounts payable and accrued expenses 36,961 28,589 8,372 Accrued real estate taxes 35,748 38,863 (3,115) Interest rate swap liabilities (d) 35,367 51,920 (16,553) Accrued payroll and other employee liabilities 25,794 27,419 (1,625) Accrued interest (e) 22,972 37,007 (14,035) Other 20,360 12,493 7,867 Accounts payable and accrued expenses $ 1,141,761 $ 852,258 $ 289,503 (a) The increase in Condominium deposit liabilities is attributable to contracted sales at ‘A‘ali‘i, The Park Ward Village, Victoria Place and Kō'ula. (b) The increase in Construction payables is attributable to an increase of $119.4 million primarily related to increased construction spend at Ward Village, the Summerlin and Bridgeland MPC developments and the Tin Building, as well as a $21.0 million charge for additional remediation costs at Waiea. These increases are partially offset by decreases of $60.3 million related to a reduction of construction spend for projects placed in service in 2020 or approaching completion, as well as costs incurred and paid for Waiea remediation activities during 2021. (c) The increase in Tenant and other deposits is primarily due to a $13.5 million deposit received in the second quarter of 2021 related to a 216-acre superpad sale in Summerlin. The sale is expected to close in the fourth quarter of 2021. (d) The decrease in Interest rate swap liabilities is due to an increase of the one-month London Interbank Offered Rate (LIBOR) forward curve for the periods presented. (e) The decrease in Accrued interest is primarily due to the repurchase of the $1.0 billion 5.375% Senior Notes due 2025, partially offset by the issuance of $650 million in 4.125% Senior Notes due 2029 and $650 million in 4.375% Senior Notes due 2031, in the first quarter of 2021.
