Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation Basis of Presentation —The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Form 10-Q and Article 10-01 of Regulation S-X for interim financial statements. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States of America ("GAAP") for complete financial statements. These unaudited consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (the "Annual Report"). 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 dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. In the opinion of management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year. Certain prior year amounts have been reclassified in the Company's consolidated financial statements and the related notes to conform to the current period presentation. Principles of Consolidation —The consolidated financial statements include the financial statements of the Company, its wholly owned subsidiaries, controlled partnerships and VIEs for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The Company's involvement with VIEs affects its financial performance and cash flows primarily through amounts recorded in "Operating lease income," "Interest income," "Earnings from equity method investments," "Real estate expense" and "Interest expense" in the Company's consolidated statements of operations. The Company has provided no financial support to those VIEs that it was not previously contractually required to provide. Consolidated VIEs —The Company consolidates VIEs for which it is considered the primary beneficiary. The liabilities of these VIEs are non-recourse to the Company and can only be satisfied from each VIE's respective assets. The Company did not have any unfunded commitments related to consolidated VIEs as of March 31, 2021 and December 31, 2020. The following table presents the assets and liabilities of the Company's consolidated VIEs as of March 31, 2021 and December 31, 2020 ($ in thousands): As of March 31, December 31, ASSETS Real estate Real estate, at cost $ 900,349 $ 899,110 Less: accumulated depreciation (68,141) (61,917) Real estate, net 832,208 837,193 Land and development, net 220,273 240,137 Other investments 31 35 Cash and cash equivalents 32,756 22,571 Accrued interest and operating lease income receivable, net 2,501 1,472 Deferred operating lease income receivable, net 31,785 29,428 Deferred expenses and other assets, net 120,288 122,591 Total assets $ 1,239,842 $ 1,253,427 LIABILITIES Accounts payable, accrued expenses and other liabilities $ 116,224 $ 115,581 Debt obligations, net 482,827 488,719 Total liabilities 599,051 604,300

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The following paragraph describes the impact on the Company's consolidated financial statements from the adoption of Accounting Standards Updates ("ASUs") on January 1, 2021. The Company adopted ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06") on January 1, 2021 using the modified retrospective approach method. Under the modified retrospective approach, the Company recorded a cumulative effect adjustment on January 1, 2021 by increasing "Debt obligations, net" by $10.0 million, increasing retained earnings by $15.9 million and decreasing "Additional paid-in capital" by $25.9 million with respect to its 3.125% senior convertible notes (refer to Note 11). Periods presented that are prior to the adoption date of January 1, 2021 will not be adjusted. In addition, upon the adoption of ASU 2020-06, the Company is required to use a modified if-converted method when calculating earnings per share. The Company will settle conversions of the 3.125% senior convertible notes by paying the conversion value in cash up to the original principal amount of the notes being converted and shares of common stock to the extent of any conversion premium. The if-converted method is modified so that interest expense is not added back to the numerator, and the denominator only includes the net number of incremental shares that would be issued upon conversion. For the remainder of the Company's significant accounting policies, refer to the Company's Annual Report. New Accounting Pronouncements —

(2) As of March 31, 2021 and December 31, 2020, the Company had $2.6 million and $5.2 million, respectively, of residential condominiums available for sale in its operating properties portfolio. Net Lease Venture —In February 2014, the Company partnered with a sovereign wealth fund to form a venture to acquire and develop net lease assets (the "Net Lease Venture") and gave a right of first offer to the venture on all new net lease investments. The Company and its partner had joint decision making rights pertaining to the acquisition of new investments. Upon the expiration of the investment period on June 30, 2018, the Company obtained control of the venture through its unilateral rights of management and disposition of the assets. As a result, the expiration of the investment period resulted in a reconsideration event under GAAP and the Company determined that the Net Lease Venture is a VIE for which the Company is the primary beneficiary. Effective June 30, 2018, the Company consolidated the Net Lease Venture as an asset acquisition under ASC 810. The Net Lease Venture had previously been accounted for as an equity method investment. The Company has an equity interest in the Net Lease Venture of approximately 51.9%.

Several of the Company's senior executives whose time is substantially devoted to the Net Lease Venture own a total of 0.6% equity ownership in the venture via co-investment. These senior executives are also entitled to an amount equal to 50% of any incentive fee received based on the 47.5% external partner's interest. Dispositions— During the three months ended March 31, 2020, the Company sold a net lease asset for net proceeds of $7.5 million and recognized an impairment of $1.7 million in connection with the sale.

Leases [Abstract]
Net Investment in Leases	Net Investment in Leases In May 2019, the Company entered into a transaction with an operator of bowling entertainment venues, consisting of the purchase of nine bowling centers for $56.7 million, of which seven were acquired from the lessee for $44.1 million, and a commitment to invest up to $55.0 million in additional bowling centers over the next several years. The new centers were added to the Company's existing master leases with the tenant. In connection with this transaction, the maturities of the master leases were extended by 15 years to 2047. In the second quarter 2020, the Company entered into a transaction with the lessee whereby it would apply $10 million of the net proceeds it received from certain sales of the lessee's facilities to the lessee's upcoming rent obligations to the Company. In exchange, the Company's obligation under the lease to acquire an equal amount of new facilities for them or to reduce their rent in the future has been terminated. In the third quarter 2020, the Company granted the lessee a nine-month rent deferral on its two wholly-owned master leases in exchange for eliminating the Company's commitment to invest up to $55.0 million in additional bowling centers over the next several years. All deferred amounts are required to be repaid with interest beginning in January 2023. As a result of the May 2019 modifications to the leases, the Company classified the leases as sales-type leases and recorded $424.1 million in "Net investment in leases" on its consolidated balance sheet. As a result of the modifications in the second and third quarter 2020, the Company reassessed this classification as required by ASC 842, and concluded that the leases should continue to be classified as sales-type leases. In May 2019, the Company determined that the seven bowling centers acquired did not qualify as a sale leaseback transaction and recorded $44.1 million in "Loans receivable and other lending investments, net" on its consolidated balance sheet (refer to Note 7). For the three months ended March 31, 2021 and 2020, the Company recognized $0.1 million and $6.9 million, respectively, of cash interest income and $8.5 million and $1.5 million, respectively, of non-cash interest income in "Interest income from sales-type leases" in the Company's consolidated statements of operations.

Credit Characteristics —As part of the Company's process for monitoring the credit quality of its loans, it performs a quarterly loan portfolio assessment and assigns risk ratings to each of its performing loans. Risk ratings, which range from 1 (lower risk) to 5 (higher risk), are based on judgments which are inherently uncertain, and there can be no assurance that actual performance will be similar to current expectation. The Company designates loans as non-performing at such time as: (1) interest payments become 90 days delinquent; (2) the loan has a maturity default; or (3) management determines it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan. All non-performing loans are placed on non-accrual status and income is only recognized in certain cases upon actual cash receipt.

Safehold Inc. —Safehold Inc. ("SAFE") is a publicly-traded company formed by the Company primarily to acquire, own, manage, finance and capitalize ground leases. Ground leases generally represent ownership of the land underlying commercial real estate projects that is net leased by the fee owner of the land to the owners/operators of the real estate projects built thereon ("Ground Leases"). As of March 31, 2021, the Company owned approximately 65.4% of SAFE's common stock outstanding. In January 2019, the Company purchased 12.5 million newly designated limited partnership units (the "Investor Units") in SAFE's operating partnership ("SAFE OP"), at a purchase price of $20.00 per unit, for a total purchase price of $250.0 million. In May 2019, after the approval of SAFE's stockholders, the Investor Units were exchanged for shares of SAFE's common stock on a one-for-one basis. Following the exchange, the Investor Units were retired. In connection with the Company's purchase of the Investor Units, it entered into a Stockholder's Agreement with SAFE on January 2, 2019. The Stockholder's Agreement: • limits the Company's discretionary voting power to 41.9% of the outstanding voting power of SAFE's common stock until its aggregate ownership of SAFE common stock is less than 41.9%; • requires the Company to cast all of its voting power in favor of three director nominees to SAFE's board who are independent of each of the Company and SAFE for three years; • subjects the Company to certain standstill provisions; and • provides the Company certain preemptive rights. In March 2020, the Company acquired 1.7 million shares of SAFE's common stock in a private placement for $80.0 million. A wholly-owned subsidiary of the Company is the external manager of SAFE and is entitled to a management fee. In addition, the Company is also the external manager of a venture in which SAFE is a member. Following are the key terms of the management agreement with SAFE: • The Company receives a fee equal to 1.0% of total SAFE equity (as defined in the management agreement) up to $1.5 billion; 1.25% of total SAFE equity (for incremental equity of $1.5 billion - $3.0 billion); 1.375% of total SAFE equity (for incremental equity of $3.0 billion - $5.0 billion); and 1.5% of total SAFE equity (for incremental equity over $5.0 billion); • Fee to be paid in cash or in shares of SAFE common stock, at the discretion of SAFE's independent directors; • The stock is locked up for two years, subject to certain restrictions; • There is no additional performance or incentive fee; • The management agreement is non-terminable by SAFE through June 30, 2023, except for cause; and • Automatic annual renewals thereafter, subject to non-renewal upon certain findings by SAFE's independent directors and payment of termination fee equal to three times the prior year's management fee. During the three months ended March 31, 2021 and 2020, the Company recorded $3.5 million and $2.9 million, respectively, of management fees pursuant to its management agreement with SAFE. The Company is also entitled to receive certain expense reimbursements, including for the allocable costs of its personnel that perform certain legal, accounting, due diligence tasks and other services that third-party professionals or outside consultants otherwise would perform. The Company has elected not to charge in full certain of the expense reimbursements while SAFE is growing its portfolio. During the three months ended March 31, 2021 and 2020, the Company recognized $1.9 million and $1.3 million, respectively, of expense reimbursements pursuant to its management agreement with SAFE.

Following is a list of investments that the Company has transacted with SAFE, all of which were approved by the Company's and SAFE's independent directors, for the periods presented: In October 2017, the Company closed on a 99-year Ground Lease and a $80.5 million construction financing commitment to support the ground-up development of a to-be-built luxury multi-family project.

The Company may make optional prepayments, subject to prepayment fees. As of March 31, 2021, the outstanding balance on the Company's Senior Term Loan was $491.9 million. Revolving Credit Facility —The Company has a secured revolving credit facility (the "Revolving Credit Facility") with a maximum capacity of $350.0 million that matures in September 2022. Outstanding borrowings under the Revolving Credit Facility are secured by pledges of the equity interests in the Company's subsidiaries that own a defined pool of assets. Borrowings under this credit facility bear interest at a floating rate indexed to one of several base rates plus a margin which adjusts upward or downward based upon the Company's corporate credit rating, ranging from 1.0% to 1.5% in the case of base rate loans and from 2.0% to 2.5% in the case of LIBOR loans.

Unsecured Notes —As of March 31, 2021, the Company has senior unsecured notes outstanding with varying fixed-rates and maturities ranging from September 2022 to February 2026. The Company's senior unsecured notes are interest only, are generally redeemable at the option of the Company and contain certain financial covenants (see below). During the three months ended March 31, 2020, repayments of unsecured notes prior to maturity resulted in losses on early extinguishment of debt of $4.1 million. This amount is included in "Loss on early extinguishment of debt, net" in the Company's consolidated statements of operations. Debt Covenants —The Company's outstanding unsecured debt securities contain corporate level covenants that include a covenant to maintain a ratio of unencumbered assets to unsecured indebtedness, as such terms are defined in the indentures governing the debt securities, of at least 1.2x and a covenant restricting certain incurrences of debt based on a fixed charge coverage ratio. If any of the Company's covenants are breached and not cured within applicable cure periods, the breach could result in acceleration of its debt securities unless a waiver or modification is agreed upon with the requisite percentage of the bondholders. The Company's Senior Term Loan and the Revolving Credit Facility contain certain covenants, including covenants relating to collateral coverage, restrictions on fundamental changes, transactions with affiliates, matters relating to the liens granted to the lenders and the delivery of information to the lenders. In particular, the Senior Term Loan requires the Company to maintain collateral coverage of at least 1.25x outstanding borrowings on the facility. The Revolving Credit Facility is secured by a borrowing base of assets and requires the Company to maintain both borrowing base asset value of at least 1.5x outstanding borrowings on the facility and a consolidated ratio of cash flow to fixed charges of at least 1.5x. The Revolving Credit Facility does not require that proceeds from the borrowing base be used to pay down outstanding borrowings provided the borrowing base asset value remains at least 1.5x outstanding borrowings on the facility. To satisfy this covenant, the Company has the option to pay down outstanding borrowings or substitute assets in the borrowing base. Under both the Senior Term Loan and the Revolving Credit Facility the Company is permitted to pay dividends provided that no material default (as defined in the relevant agreement) has occurred and is continuing or would result therefrom and the Company remains in compliance with its financial covenants after giving effect to the dividend. The Company's Senior Term Loan and the Revolving Credit Facility contain cross default provisions that would allow the lenders to declare an event of default and accelerate the Company's indebtedness to them if the Company fails to pay amounts due in respect of its other recourse indebtedness in excess of specified thresholds or if the lenders under such other indebtedness are otherwise permitted to accelerate such indebtedness for any reason. The indentures governing the Company's unsecured public debt securities permit the bondholders to declare an event of default and accelerate the Company's indebtedness to them if the Company's other recourse indebtedness in excess of specified thresholds is not paid at final maturity or if such indebtedness is accelerated.

Dividends are cumulative from the date of original issue and are payable quarterly in arrears on or before the 15th day of each March, June, September and December or, if not a business day, the next succeeding business day. Any dividend payable on the preferred stock for any partial dividend period will be computed on the basis of a 360-day year consisting of twelve (2) The Company declared and paid dividends of $2.0 million, $1.5 million and $2.3 million on its Series D, G and I Cumulative Redeemable Preferred Stock during both the three months ended March 31, 2021 and 2020. The character of the 2020 dividends was 100% return of capital. There are no dividend arrearages on any of the preferred shares currently outstanding. (3) The Company may, at its option, redeem the Series G and I Preferred Stock, in whole or in part, at any time and from time to time, for cash at a redemption price equal to 100% of the liquidation preference of $25.00 per share, plus accrued and unpaid dividends, if any, to the redemption date. Dividends —To maintain its qualification as a REIT, the Company must annually distribute, at a minimum, an amount equal to 90% of its taxable income, excluding net capital gains, and must distribute 100% of its taxable income (including net capital gains) to eliminate corporate federal income taxes payable by the REIT. The Company has recorded NOLs and may record NOLs in the future, which may reduce its taxable income in future periods and lower or eliminate entirely the Company's obligation to pay dividends for such periods in order to maintain its REIT qualification. As of December 31, 2019, the Company had $460.6 million of NOL carryforwards at the corporate REIT level that can generally be used to offset both ordinary taxable income and capital gain net income in future years. The NOL carryforwards will begin to expire in 2032 and will fully expire in 2036 if unused. The amount of NOL carryforwards as of December 31, 2020 will be determined upon finalization of the Company's 2020 tax return. Because taxable income differs from cash flow from operations due to non-cash revenues and expenses (such as depreciation and certain asset impairments), in certain circumstances, the Company may generate operating cash flow in excess of its dividends, or alternatively, may need to make dividend payments in excess of operating cash flows. The Senior Term Loan and the Revolving Credit Facility permit the Company to pay common dividends with no restrictions so long as the Company is not in default on any of its debt obligations. The Company declared common stock dividends of $8.2 million, or $0.11 per share, for the three months ended March 31, 2021 and $7.8 million, or $0.10 per share, for the three months ended March 31, 2020. The character of the 2020 dividends was 100% return of capital. Stock Repurchase Program —The Company may repurchase shares in negotiated transactions or open market transactions, including through one or more trading plans. During the three months ended March 31, 2021, the Company repurchased 0.7 million shares of its outstanding common stock for $12.4 million, for an average cost of $17.20 per share. During the three months ended March 31, 2020, the Company repurchased 1.0 million shares of its outstanding common stock for $12.0 million, for an average cost of $12.51 per share. In February 2021, the Company's Board of Directors authorized an increase to the stock repurchase program to $50.0 million. As of March 31, 2021, the Company had remaining authorization to repurchase up to $40.1 million of common stock under its stock repurchase program. Accumulated Other Comprehensive Income (Loss) —"Accumulated other comprehensive income (loss)" reflected in the Company's shareholders' equity is comprised of the following ($ in thousands): As of March 31, 2021 December 31, 2020 Unrealized gains on available-for-sale securities $ 3,563 $ 4,594 Unrealized losses on cash flow hedges (41,254) (53,075) Unrealized losses on cumulative translation adjustment (4,167) (4,199) Accumulated other comprehensive loss $ (41,858) $ (52,680)

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation Plans and Employee Benefits	Stock-Based Compensation Plans and Employee Benefits Stock-Based Compensation —The Company recorded stock-based compensation expense, including the expense related to performance incentive plans (see below), of $5.5 million and $16.3 million for the three months ended March 31, 2021 and 2020, respectively, in "General and administrative" in the Company's consolidated statements of operations. Performance Incentive Plans —The Company's Performance Incentive Plans ("iPIP") are designed to provide, primarily to senior executives and select professionals engaged in the Company's investment activities, long-term compensation which has a direct relationship to the realized returns on investments included in the plans. Awards vest over six years, with 40% being vested at the end of the second year and 15% each year thereafter. 2019-2022 iPIP Plans —The Company's 2019-2020 and 2021-2022 iPIP plans are equity-classified awards which are measured at the grant date fair value and recognized as compensation cost in "General and administrative" in the Company's consolidated statements of operations and "Noncontrolling interests" in the Company's consolidated statements of changes in equity over the requisite service period. Investments in the 2019-2022 iPIP plans are held by consolidated subsidiaries of the Company and have two ownership classes, class A units and class B units. The Company owns 100% of the class A units and the class B units were issued to employees as long-term compensation. Except for certain clawback provisions, participants can retain vested class B units upon their termination of employment with the Company. The class B units are entitled to distributions from the net cash realized from the investments in the plan after the Company, through its ownership of the class A units, has received a specified return on its invested capital and a return of its invested capital. Distributions on the class B units are also subject to reductions under a total shareholder return ("TSR") adjustment. The fair value of the class B units was determined using a model that forecasts the underlying cash flows from the investments within the entity to which the class B units have ownership rights. During the three months ended March 31, 2021 and 2020, the Company recorded $1.4 million and $0.7 million, respectively, of expense related to the 2019-2022 iPIP plans. Distributions on the class B units will be 50% in cash and 50% in shares of the Company's common stock or in shares of SAFE's common stock owned by the Company. The following is a summary of the status of the Company’s equity-classified iPIP plans and changes during the three months ended March 31, 2021. iPIP Investment Pool 2019-2020 2021-2022 Points at beginning of period 97.40 — Granted — 94.00 Forfeited (0.20) — Points at end of period 97.20 94.00 2013-2018 iPIP Plans —The remainder of the Company's iPIP plans, as shown in the table below, are liability-classified awards and are remeasured each reporting period at fair value until the awards are settled. Certain employees will be granted awards that entitle employees to receive the residual cash flows from the investments in the plans after the Company has received a specified return on its invested capital and a return of its invested capital. Awards are also subject to reductions under a TSR adjustment. The fair value of awards is determined using a model that forecasts the Company's projected investment performance. Settlement of the awards will be 50% in cash and 50% in shares of the Company's common stock or in shares of SAFE's common stock owned by the Company. The following is a summary of the status of the Company’s liability-classified iPIP plans and changes during the three months ended March 31, 2021. iPIP Investment Pool 2013-2014 2015-2016 2017-2018 Points at beginning of period 80.17 70.40 73.34 Forfeited — — — Points at end of period 80.17 70.40 73.34 During the three months ended March 31, 2021 and 2020, the Company recorded $2.4 million and $14.3 million, respectively, of expense related to the 2013-2018 iPIP plans.

Fair Value Disclosures [Abstract]
Fair Values	Fair Values Fair value represents the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The following fair value hierarchy prioritizes the inputs to be used in valuation techniques to measure fair value: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Certain of the Company's assets and liabilities are recorded at fair value either on a recurring or non-recurring basis. Assets required to be marked-to-market and reported at fair value every reporting period are classified as being valued on a recurring basis. Assets not required to be recorded at fair value every period may be recorded at fair value if a specific provision or other impairment is recorded within the period to mark the carrying value of the asset to market as of the reporting date. Such assets are classified as being valued on a non-recurring basis. The following fair value hierarchy table summarizes the Company's assets and liabilities recorded at fair value on a recurring and non-recurring basis by the above categories ($ in thousands): Fair Value Using Total Quoted market Significant other Significant As of March 31, 2021 Recurring basis: Derivative liabilities (1) $ 14,178 $ — $ 14,178 $ — Available-for-sale securities (1) 24,043 — — 24,043 Loan receivable held for sale (refer to Note 7) 16,086 — — 16,086 Non-recurring basis: Other investments (2) 75,402 — 75,402 — As of December 31, 2020 Recurring basis: Derivative liabilities (1) 18,926 — 18,926 — Available-for-sale securities (1) 25,274 — — 25,274 Non-recurring basis: Impaired land and development (3) 6,078 — — 6,078 ____________________________________________________________ (1) The fair value of the Company's derivatives are based upon widely accepted valuation techniques utilized by a third-party specialist using observable inputs such as interest rates and contractual cash flow and are classified as Level 2. The fair value of the Company's available-for-sale securities are based upon unadjusted third-party broker quotes and are classified as Level 3. (2) During the three months ended March 31, 2021, the Company identified an observable price change in an equity security held by the Company as evidenced by an orderly private issuance of similar securities by the same issuer and, as such, classified such observable price change as Level 2.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with the instructions to Form 10-Q and Article 10-01 of Regulation S-X for interim financial statements. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles in the United States of America ("GAAP") for complete financial statements. These unaudited consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020 (the "Annual Report"). 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 dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. In the opinion of management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for the interim periods presented. Such operating results may not be indicative of the expected results for any other interim periods or the entire year. Certain prior year amounts have been reclassified in the Company's consolidated financial statements and the related notes to conform to the current period presentation.
Principles of Consolidation	Principles of Consolidation —The consolidated financial statements include the financial statements of the Company, its wholly owned subsidiaries, controlled partnerships and VIEs for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The Company's involvement with VIEs affects its financial performance and cash flows primarily through amounts recorded in "Operating lease income," "Interest income," "Earnings from equity method investments," "Real estate expense" and "Interest expense" in the Company's consolidated statements of operations. The Company has provided no financial support to those VIEs that it was not previously contractually required to provide.
Adoption of Accounting Standards Updates and New Accounting Pronouncements	The following paragraph describes the impact on the Company's consolidated financial statements from the adoption of Accounting Standards Updates ("ASUs") on January 1, 2021. The Company adopted ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06") on January 1, 2021 using the modified retrospective approach method. Under the modified retrospective approach, the Company recorded a cumulative effect adjustment on January 1, 2021 by increasing "Debt obligations, net" by $10.0 million, increasing retained earnings by $15.9 million and decreasing "Additional paid-in capital" by $25.9 million with respect to its 3.125% senior convertible notes (refer to Note 11). Periods presented that are prior to the adoption date of January 1, 2021 will not be adjusted. In addition, upon the adoption of ASU 2020-06, the Company is required to use a modified if-converted method when calculating earnings per share. The Company will settle conversions of the 3.125% senior convertible notes by paying the conversion value in cash up to the original principal amount of the notes being converted and shares of common stock to the extent of any conversion premium. The if-converted method is modified so that interest expense is not added back to the numerator, and the denominator only includes the net number of incremental shares that would be issued upon conversion.
