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 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, 2018 (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 September 30, 2019 . The following table presents the assets and liabilities of the Company's consolidated VIEs as of September 30, 2019 and December 31, 2018 ($ in thousands): As of September 30, December 31, ASSETS Real estate Real estate, at cost $ 888,277 $ 848,052 Less: accumulated depreciation (31,458 ) (15,365 ) Real estate, net 856,819 832,687 Land and development, net 282,082 279,031 Other investments 52 72 Cash and cash equivalents 26,153 25,219 Accrued interest and operating lease income receivable, net 858 1,302 Deferred operating lease income receivable, net 16,958 8,972 Deferred expenses and other assets, net 137,261 167,324 Total assets $ 1,320,183 $ 1,314,607 LIABILITIES Accounts payable, accrued expenses and other liabilities $ 117,136 $ 106,907 Debt obligations, net 485,032 485,000 Total liabilities 602,168 591,907 Unconsolidated VIEs —The Company has investments in VIEs where it is not the primary beneficiary and accordingly the VIEs have not been consolidated in the Company's consolidated financial statements. As of September 30, 2019 , the Company's maximum exposure to loss from these investments does not exceed the sum of the $115.8 million carrying value of the investments, which are classified in "Other investments" on the Company's consolidated balance sheets, and $21.6 million

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies The following paragraphs describe the impact on the Company's consolidated financial statements from the adoption of Accounting Standards Updates ("ASUs") on January 1, 2019. ASU 2016-02 and ASU 2018-11—Accounting Standards Update ("ASU") 2016-02, Leases ("ASU 2016-02") required the recognition of right-of-use lease assets and lease liabilities by the Company as lessee for those leases classified as operating or finance leases, both measured at the present value of the lease payments, on its consolidated balance sheets. For operating lease arrangements as of December 31, 2018 for which the Company was the lessee, primarily under leases of office space and certain ground leases, the Company recorded operating lease right-of-use assets of $31.6 million in "Deferred expenses and other assets, net" and operating lease liabilities of $31.6 million in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets. In addition, the Company entered into finance leases in 2019, and as of September 30, 2019, recorded finance lease right-of-use assets of $145.5 million in "Deferred expenses and other assets, net" and finance lease liabilities of $147.1 million in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets (refer to Significant Accounting Policies below). The Company, as lessor, recognizes certain of its leases on net lease properties as sales-type leases and records the leases as "Net investment in leases" on the Company's consolidated balance sheets (refer to Note 5). For the Company's leases which qualify as sales-type leases, the Company records "Interest income from sales-type leases" in the Company's consolidated statements of operations. The amount recorded as interest income from sales-type leases in any given period will likely be different than the straight-line lease income that would have been recorded under the superseded guidance. Management elected the practical expedient package that allowed the Company: (a) to not reassess whether any expired or existing contracts entered into prior to January 1, 2019 are or contain leases; (b) to not reassess the lease classification for any expired or existing leases entered into prior to January 1, 2019; and (c) to not reassess initial direct costs for any expired or existing leases entered into prior to January 1, 2019. In addition, the Company elected to not record on its consolidated balance sheets leases whose term is less than 12 months at lease inception. ASU 2018-11, Leases amended ASU 2016-02 so that: (i) entities could elect to not recast the comparative periods presented when transitioning to ASC 842 by allowing entities to change their initial application to the beginning of the period of adoption; and (ii) provided lessors with a practical expedient to not separate non-lease components from the associated lease component of the contractual payments if certain conditions are met. Management elected both of these provisions. ASU 2018-16—ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes was issued in October 2018 and expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The adoption of ASU 2018-16 did not have a material impact on the Company's consolidated financial statements. Significant Accounting Policies Real estate available and held for sale— The Company reports real estate assets to be sold at the lower of their carrying amount or estimated fair value less costs to sell and classifies them as “Real estate available and held for sale” on the Company's consolidated balance sheets. If the estimated fair value less costs to sell is less than the carrying value, the difference will be recorded as an impairment charge. Impairment for real estate assets disposed of or classified as held for sale are included in "Impairment of assets" in the Company's consolidated statements of operations. Once a real estate asset is classified as held for sale, depreciation expense is no longer recorded. The Company classifies its real estate assets as held for sale in the period in which all of the following conditions are met: (i) the Company commits to a plan and has the authority to sell the asset; (ii) the asset is available for sale in its current condition; (iii) the Company has initiated an active marketing plan to locate a buyer for the asset; (iv) the sale of the asset is both probable and expected to qualify for full sales recognition within a period of 12 months; (v) the asset is being actively marketed for sale at a price that is reflective of its current fair value; and (vi) the Company does not anticipate changes to its plan to sell the asset. Net Investment in Leases —Net investment in leases are recognized when the Company's leases qualify as sales-type leases. The net investment in leases is initially measured at the present value of the fixed and determinable lease payments, including any guaranteed or unguaranteed residual value of the asset at the end of the lease, discounted at the rate implicit in the lease. If a lease qualifies as a sales-type lease, it is further evaluated to determine whether the transaction is considered a sale leaseback transaction. If the sales-type lease does not qualify as a sale leaseback transaction, the lease is considered a financing receivable and is recognized in accordance with ASC 310 (refer to Note 5) and recorded in "Loans receivable and other lending investments, net" on the Company's consolidated balance sheets. Interest Income from Sales-Type Leases —Interest income from sales-type leases is recognized in "Interest income from sales-type leases" in the Company's consolidated statements of operations under the effective interest method. The effective interest method produces a constant yield on the net investment in the lease over the term of the lease. Rent payments that are not fixed and determinable at lease inception, such as percentage rent and CPI adjustments, are not included in the effective interest method calculation and are recognized in "Interest income from sales-type leases" in the Company's consolidated statements of operations in the period earned. Restricted cash— The following table provides a reconciliation of the cash and cash equivalents and restricted cash reported in the Company's consolidated balance sheets that total to the same amount as reported in the consolidated statements of cash flows (in thousands): September 30, 2019 December 31, 2018 September 30, 2018 December 31, 2017 Cash and cash equivalents $ 917,309 $ 931,751 $ 757,384 $ 657,688 Restricted cash included in deferred expenses and other assets, net (1) 61,509 42,793 34,974 20,045 Total cash, cash equivalents and restricted cash reported in the consolidated statements of cash flows $ 978,818 $ 974,544 $ 792,358 $ 677,733 _______________________________________________________________________________ (1) Restricted cash represents amounts required to be maintained under certain of the Company's debt obligations, loans, leasing, land development, sale and derivative transactions. Deferred expenses and other assets and accounts payable, accrued expenses and other liabilities— Effective January 1, 2019 with the adoption of ASU 2016-02, the Company, as lessee, records right-of-use lease assets in "Deferred expenses and other assets" and lease liabilities in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets for operating and finance leases, both measured at the present value of the lease payments. Some of the Company's lease agreements include extension options, which are not included in the lease payments unless the extensions are reasonably certain to be exercised. For operating leases, the Company recognizes a single lease cost for office leases in "General and administrative" and a single lease cost for ground leases in "Real estate expense" in the consolidated statements of operations, calculated so that the cost of the lease is allocated generally on a straight-line basis over the term of the lease, and classifies all cash payments within operating activities in the consolidated statements of cash flows. For finance leases, the Company recognizes amortization of the right-of-use assets on a straight-line basis over the term of the lease in "Depreciation and amortization" and interest expense on the lease liability using the effective interest method in "Interest expense" in the consolidated statements of operations. Repayments of the principal portion of the finance lease liability are classified within financing activities in the consolidated statements of cash flows and payments of interest on a finance lease liability are classified within operating activities in the consolidated statement of cash flows. For the remainder of the Company's significant accounting policies, refer to the Company's Annual Report. New Accounting Pronouncements — In June 2016 , the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which was issued to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments held by a reporting entity. This amendment replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company currently records a general reserve that covers performing loans and reserves for loan losses are recorded when: (i) available information as of each balance sheet date indicates that it is probable a loss has occurred in the portfolio; and (ii) the amount of the loss can be reasonably estimated. The formula-based general reserve is derived from estimated principal default probabilities and loss severities applied to groups of loans based upon risk ratings assigned to loans with similar risk characteristics during our quarterly loan portfolio assessment. The Company estimates loss rates based on historical realized losses experienced within its portfolio and take into account current economic conditions affecting the commercial real estate market when establishing appropriate time frames to evaluate loss experience. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Management is currently evaluating the impact from ASU 2016-13 on the Company's consolidated financial statements. In May 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments ("ASU 2019-04") to clarify certain accounting topics from previously issued ASUs, including ASU 2016-13. ASU 2019-04 addresses certain aspects of ASU 2016-13, including but not limited to, accrued interest receivable, loan recoveries, interest rate projections for variable-rate financial instruments and expected prepayments. ASU 2019-04 provides alternatives that allow entities to measure credit losses on accrued interest separate from credit losses on the principal portion of a loan, clarifies that entities should include expected recoveries in the measurement of credit losses, allows entities to consider future interest rates when measuring credit losses and can elect to adjust effective interest rates used to discount expected cash flows for expected loan prepayments. ASU 2019-04 is effective upon the adoption of ASU 2016-13. Management is currently evaluating the impact of ASU 2019-04 on the Company’s consolidated financial statements.

The Company's loans individually evaluated for impairment primarily represent loans on non-accrual status; therefore, the unamortized amounts associated with these loans are not currently being amortized into income. (2) The carrying value of these loans include unamortized discounts, premiums, deferred fees and costs totaling net discounts of $1.3 million and $3.1 million as of September 30, 2019 and December 31, 2018 , respectively. (3) The Company's recorded investment in loans as of September 30, 2019 and December 31, 2018 includes accrued interest of $4.2 million and $4.9 million , respectively, which is included in "Accrued interest and operating lease income receivable, net" on the Company's consolidated balance sheets. As of September 30, 2019, excludes $44.2 million of other lending investments that are evaluated for impairment when, based upon current information and events, the Company believes it is probable that it will be unable to collect all amounts due under the contractual terms of the lease (refer to Note 5). As of September 30, 2019 and December 31, 2018 , the total amounts exclude $107.7 million and $122.1 million , respectively, of securities that are evaluated for impairment under ASC 320. 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.

(2) During the three and nine months ended September 30, 2019, equity in earnings (losses) includes $8.2 million of income resulting from the sale of a property at one of the Company's equity method investments. (3) For the nine months ended September 30, 2018, equity in earnings (losses) includes a $10.0 million impairment on a foreign equity method investment due to local market conditions. Safehold Inc. —Safehold Inc. ("SAFE"), formerly known as Safety, Income & Growth Inc., 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"). On January 2, 2019, the Company purchased 12,500,000 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 . The purpose of the investment was to allow SAFE to fund additional Ground Lease acquisitions and originations. Each Investor Unit received distributions equivalent to distributions declared and paid on one share of SAFE's common stock. The Investor Units had no voting rights. They had limited protective consent rights over certain matters such as amendments to the terms of the Investor Units that would adversely affect the Investor Units. 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 for two years ; • restricts the Company's ability to transfer shares of SAFE common stock issued in exchange for Investor Units, or "Exchange Shares," for one year after their issuance; • prohibits the Company from transferring shares of SAFE common stock representing more than 20% of the outstanding SAFE common stock in one transaction or a series of related transactions to any person or group, other than pursuant to a widely distributed public offering, unless SAFE's other stockholders have participation rights in the transaction; and • provides the Company certain preemptive rights. A wholly-owned subsidiary of the Company is the external manager of SAFE and is entitled to a management fee. Following are the key terms of the management agreement: • The Company received no management fee through June 30, 2018, which covered the first year of the management agreement; • 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; • From January 1, 2019 through June 30, 2022, the management agreement is non-terminable by SAFE 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, subject to SAFE having raised $820 million of total equity since inception. In August 2019, the Company acquired 6.0 million shares of SAFE's common stock in a private placement for $168.0 million . As of September 30, 2019 , the Company owned approximately 67.1% of SAFE's common stock outstanding.

During the three and nine months ended September 30, 2019 , the Company received 56,610 shares and 178,215 shares, respectively, of SAFE common stock for payment of management fees. The Company is also entitled to receive 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.

Net Lease Venture —In February 2014, the Company partnered with a sovereign wealth fund to form the Net Lease Venture to acquire and develop net lease assets 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 Company recorded a gain of $67.9 million in "Gain on consolidation of equity method investment" in the Company's consolidated statement of operations as a result of the consolidation.

Net Lease Venture II —In July 2018, the Company entered into a new venture ("Net Lease Venture II") with an investment strategy similar to the Net Lease Venture. The Net Lease Venture II has a right of first offer on all new net lease investments (excluding Ground Leases) originated by the Company. Net Lease Venture II is a voting interest entity and the Company has an equity interest in the venture of approximately 51.9% , which will be accounted for as an equity method investment, and is responsible for managing the venture in exchange for a management fee and incentive fee. During the three and nine months ended September 30, 2019 , the Company recorded $0.4 million and $1.1 million , respectively, of management fees from the Net Lease Venture II.

In August 2016, the Company upsized the facility to $500.0 million . The initial $450.0 million of the 2016 Senior Term Loan was issued at 99% of par and the upsize was issued at par.

An undrawn credit facility commitment fee ranges from 0.25% to 0.45% , based on corporate credit ratings. At maturity, the Company may convert outstanding borrowings to a one year term loan which matures in quarterly installments through September 2023.

Such subsidiaries are subject to contractual restrictions under the terms of such credit facilities, including restrictions on incurring new debt (subject to certain exceptions). As of September 30, 2019 , Collateral Assets includes $412.0 million carrying value of assets held by entities pledged as collateral for the 2015 Revolving Credit Facility that is undrawn as of September 30, 2019 . (2) As of September 30, 2019 and December 31, 2018 , the amounts presented exclude general reserves for loan losses of $8.7 million and $13.0 million , respectively. (3) As of September 30, 2019 and December 31, 2018 , the amounts presented exclude loan participations of $33.1 million and $22.5 million , respectively. 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 1.2 x and a covenant not to incur additional indebtedness (except for incurrences of permitted debt), if on a pro forma basis the Company's consolidated fixed charge coverage ratio, determined in accordance with the indentures governing the Company's debt securities, is 1.5 x or lower. 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. If the Company's ability to incur additional indebtedness under the fixed charge coverage ratio is limited, the Company is permitted to incur indebtedness for the purpose of refinancing existing indebtedness and for other permitted purposes under the indentures. The Company's 2016 Senior Term Loan and the 2015 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 2016 Senior Term Loan requires the Company to maintain collateral coverage of at least 1.25 x outstanding borrowings on the facility. The 2015 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 1.5 x outstanding borrowings on the facility and a consolidated ratio of cash flow to fixed charges of at least 1.5 x. The 2015 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 1.5 x 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. The Company may not pay common dividends if it ceases to qualify as a REIT. In June 2018, the Company amended the terms of the 2016 Senior Term Loan and the 2015 Revolving Credit Facility to include the ability to pay common dividends with no restrictions so long as the Company is not in default on any of its debt obligations. The Company's 2016 Senior Term Loan and the 2015 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company's use of derivative financial instruments has historically been limited to the utilization of interest rate swaps, interest rate caps and foreign exchange contracts. The principal objective of such financial instruments is to minimize the risks and/or costs associated with the Company's operating and financial structure and to manage its exposure to interest rates and foreign exchange rates. The Company may have derivatives that are not designated as hedges because they do not meet the strict hedge accounting requirements. Although not designated as hedges, such derivatives are entered into to manage the Company's exposure to interest rate movements, foreign exchange rate movements and other identified risks. The table below presents the fair value of the Company's derivative financial instruments as well as their classification on the consolidated balance sheets as of September 30, 2019 and December 31, 2018 ($ in thousands) (1) : Derivative Assets Derivative Liabilities As of September 30, 2019 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives Designated in Hedging Relationships Interest rate swaps Deferred expenses and other assets, net $ 94 Accounts payable, accrued expenses and other liabilities $ 11,572 Total $ 94 $ 11,572 Derivative Assets Derivative Liabilities As of December 31, 2018 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives Designated in Hedging Relationships Interest rate swaps Deferred expenses and other assets, net $ 3,669 Accounts payable, accrued expenses and other liabilities $ 10,244 Total $ 3,669 $ 10,244 _________________________________________________________ (1) Over the next 12 months, the Company expects that $4.8 million related to cash flow hedges will be reclassified from "Accumulated other comprehensive income (loss)" as a reduction to interest expense. As of December 31, 2018 , the Company posted cash collateral of $6.4 million in connection with its derivatives which were in a liability position and would not have been required to post any additional collateral to settle these contracts had the Company been declared in default on its derivative obligations.

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 30 -day months. Dividends will be payable to holders of record as of the close of business on the first day of the calendar month in which the applicable dividend payment date falls or on another date designated by the Company's Board of Directors for the payment of dividends that is not more than 30 nor less than 10 days prior to the dividend payment date. (2) The Company declared and paid dividends of $6.0 million , $4.6 million and $7.0 million on its Series D, G and I Cumulative Redeemable Preferred Stock during the nine months ended September 30, 2019 and 2018 , respectively. The Company declared and paid dividends of $6.8 million on its Series J Convertible Perpetual Preferred Stock during the nine months ended September 30, 2019 and 2018 . The character of the 2018 dividends was 100% capital gain distribution, of which 26.02% represented unrecaptured section 1250 gain and 73.98% represented long term capital gain. 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. (4) Each share of the Series J Preferred Stock is convertible at the holder's option at any time into shares of the Company's common stock. The Company may, at its option, redeem the Series J 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 $50.00 per share, plus accrued and unpaid dividends, if any, to the redemption date. The conversion rate as of September 30, 2019 was 4.0918 shares of the Company's common stock (equal to a conversion price of approximately $12.22 per share). The conversion rate is subject to adjustment from time to time for specified events. 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, 2018, the Company had $567.7 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 2031 and will fully expire in 2036 if unused. 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 2016 Senior Term Loan and the 2015 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 $19.0 million , or $0.29 per share, for the nine months ended September 30, 2019 .

During the nine months ended September 30, 2018 , the Company repurchased 0.8 million shares of its outstanding common stock for $8.3 million , for an average cost of $10.22 per share.

Awards vest over six years , with 40% being vested at the end of the second year and 15% each year thereafter. 2019-2020 iPIP Plan —The Company's 2019-2020 iPIP plan is an equity-classified award which is 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 2019-2020 iPIP plan will be held by a consolidated subsidiary of the Company that has 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 nine months ended September 30, 2019 , the Company recorded $2.0 million of expense related to the 2019-2020 iPIP plan. Distributions on the class B units will be 50% in cash and 50% in shares of the Company's common stock. 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. The following is a summary of the status of the Company’s liability-classified iPIP plans and changes during the nine months ended September 30, 2019 . iPIP Investment Pool 2013-2014 2015-2016 2017-2018 Points at beginning of period 85.77 79.41 82.43 Granted — — — Forfeited (1.60 ) (2.73 ) (3.72 ) Points at end of period 84.17 76.68 78.71 During the nine months ended September 30, 2019 , the Company made distributions to participants in the 2013-2014 investment pool.

For the three and nine months ended September 30, 2019 and the three months ended September 30, 2018, the effect of certain of the Company's restricted stock awards were anti-dilutive. The Company will settle conversions of the 3.125% Convertible Notes (refer to Note 11) 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 amount of cash and shares of common stock, if any, due upon conversion will be based on a daily conversion value calculated for each trading day in a 40 consecutive day observation period. Based upon the conversion price of the 3.125% Convertible Notes, no shares of common stock would have been issuable upon conversion of the 3.125% Convertible Notes for the three and nine months ended September 30, 2019 and therefore the 3.125%

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 prices in active markets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) As of September 30, 2019 Recurring basis: Derivative assets (1) $ 94 $ — $ 94 $ — Derivative liabilities (1) 11,572 — 11,572 — Available-for-sale securities (1) 24,102 — — 24,102 As of December 31, 2018 Recurring basis: Derivative assets (1) $ 3,669 $ — $ 3,669 $ — Derivative liabilities (1) 10,244 — 10,244 — Available-for-sale securities (1) 21,661 — — 21,661 Non-recurring basis: Impaired real estate (2) 29,400 — — 29,400 Impaired real estate available and held for sale (3) 19,300 — — 19,300 Impaired land and development (4) 78,400 — — 78,400 ____________________________________________________________ (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) The Company recorded aggregate impairments of $76.3 million on three real estate assets with an estimated aggregate fair value of $29.4 million . The impairments were as follows: a. A $23.2 million impairment on a commercial operating property based on a decline in expected operating performance. The fair value is based on the Company's estimate of the recoverability of its investment in the project. b. A $6.0 million impairment on a property based on a strategic decision to sell the asset. The fair value is based on purchase offers received from third parties, which is consistent with the Company's estimate of fair value. c. A $47.1 million impairment on a commercial operating property based on a strategic decision to sell the asset. The fair value is based on purchase offers received from third parties, which is consistent with the Company's estimate of fair value. (3) The Company recorded aggregate impairments of $3.7 million on two real estate assets held for sale. The fair values are based on market comparable sales. (4) The Company recorded aggregate impairments of $55.4 million on four land and development assets with an estimated aggregate fair value of $78.4 million . The impairments were as follows: a. A $25.0 million impairment on a waterfront land and development asset based on a strategic decision to sell the asset. The fair value is based on purchase offers received from third parties, which is consistent with the Company's estimate of fair value. b. A $21.6 million impairment on a master planned community based on a strategic decision to sell the asset. The fair value is based on purchase offers received from third parties, which is consistent with the Company's estimate of fair value. c. A $6.9 million impairment on an infill land and development asset based on the deterioration of the asset. The fair value is based on purchase offers received from third parties, which is consistent with the Company's estimate of fair value. d. A $1.9 million impairment on a waterfront land and development asset based on the sale of the asset in 2019. The following table summarizes changes in Level 3 available-for-sale securities reported at fair value on the Company's consolidated balance sheets for the nine months ended September 30, 2019 and 2018 ($ in thousands): 2019 2018 Beginning balance $ 21,661 $ 22,842 Repayments (45 ) (46 ) Unrealized gains (losses) recorded in other comprehensive income 2,486 (1,514 ) Ending balance $ 24,102 $ 21,282 Fair values of financial instruments— The Company's estimated fair values of its loans receivable and other lending investments and outstanding debt was $0.8 billion and $4.0 billion , respectively, as of September 30, 2019 and $1.0 billion and $3.5 billion , respectively, as of December 31, 2018 . The Company determined that the significant inputs used to value its loans receivable and other lending investments and debt obligations fall within Level 3 of the fair value hierarchy. The carrying value of other financial instruments including cash and cash equivalents, restricted cash, accrued interest receivable, net investment in leases and accounts payable, approximate the fair values of the instruments. Cash and cash equivalents and restricted cash values are considered Level 1 on the fair value hierarchy. The fair value of other financial instruments, including derivative assets and liabilities, is included in the fair value hierarchy table above.

Accounting Policies [Abstract]
New and adopted accounting pronouncements	New Accounting Pronouncements — In June 2016 , the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), which was issued to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments held by a reporting entity. This amendment replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company currently records a general reserve that covers performing loans and reserves for loan losses are recorded when: (i) available information as of each balance sheet date indicates that it is probable a loss has occurred in the portfolio; and (ii) the amount of the loss can be reasonably estimated. The formula-based general reserve is derived from estimated principal default probabilities and loss severities applied to groups of loans based upon risk ratings assigned to loans with similar risk characteristics during our quarterly loan portfolio assessment. The Company estimates loss rates based on historical realized losses experienced within its portfolio and take into account current economic conditions affecting the commercial real estate market when establishing appropriate time frames to evaluate loss experience. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Management is currently evaluating the impact from ASU 2016-13 on the Company's consolidated financial statements. In May 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments ("ASU 2019-04") to clarify certain accounting topics from previously issued ASUs, including ASU 2016-13. ASU 2019-04 addresses certain aspects of ASU 2016-13, including but not limited to, accrued interest receivable, loan recoveries, interest rate projections for variable-rate financial instruments and expected prepayments. ASU 2019-04 provides alternatives that allow entities to measure credit losses on accrued interest separate from credit losses on the principal portion of a loan, clarifies that entities should include expected recoveries in the measurement of credit losses, allows entities to consider future interest rates when measuring credit losses and can elect to adjust effective interest rates used to discount expected cash flows for expected loan prepayments. ASU 2019-04 is effective upon the adoption of ASU 2016-13. Management is currently evaluating the impact of ASU 2019-04 on the Company’s consolidated financial statements. The following paragraphs describe the impact on the Company's consolidated financial statements from the adoption of Accounting Standards Updates ("ASUs") on January 1, 2019. ASU 2016-02 and ASU 2018-11—Accounting Standards Update ("ASU") 2016-02, Leases ("ASU 2016-02") required the recognition of right-of-use lease assets and lease liabilities by the Company as lessee for those leases classified as operating or finance leases, both measured at the present value of the lease payments, on its consolidated balance sheets. For operating lease arrangements as of December 31, 2018 for which the Company was the lessee, primarily under leases of office space and certain ground leases, the Company recorded operating lease right-of-use assets of $31.6 million in "Deferred expenses and other assets, net" and operating lease liabilities of $31.6 million in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets. In addition, the Company entered into finance leases in 2019, and as of September 30, 2019, recorded finance lease right-of-use assets of $145.5 million in "Deferred expenses and other assets, net" and finance lease liabilities of $147.1 million in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets (refer to Significant Accounting Policies below). The Company, as lessor, recognizes certain of its leases on net lease properties as sales-type leases and records the leases as "Net investment in leases" on the Company's consolidated balance sheets (refer to Note 5). For the Company's leases which qualify as sales-type leases, the Company records "Interest income from sales-type leases" in the Company's consolidated statements of operations. The amount recorded as interest income from sales-type leases in any given period will likely be different than the straight-line lease income that would have been recorded under the superseded guidance. Management elected the practical expedient package that allowed the Company: (a) to not reassess whether any expired or existing contracts entered into prior to January 1, 2019 are or contain leases; (b) to not reassess the lease classification for any expired or existing leases entered into prior to January 1, 2019; and (c) to not reassess initial direct costs for any expired or existing leases entered into prior to January 1, 2019. In addition, the Company elected to not record on its consolidated balance sheets leases whose term is less than 12 months at lease inception. ASU 2018-11, Leases amended ASU 2016-02 so that: (i) entities could elect to not recast the comparative periods presented when transitioning to ASC 842 by allowing entities to change their initial application to the beginning of the period of adoption; and (ii) provided lessors with a practical expedient to not separate non-lease components from the associated lease component of the contractual payments if certain conditions are met. Management elected both of these provisions. ASU 2018-16—ASU 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate ("SOFR") Overnight Index Swap ("OIS") Rate as a Benchmark Interest Rate for Hedge Accounting Purposes was issued in October 2018 and expands the list of U.S. benchmark interest rates permitted in the application of hedge accounting by adding the OIS rate based on SOFR as an eligible benchmark interest rate. The adoption of ASU 2018-16 did not have a material impact on the Company's consolidated financial statements.
Real estate available and held for sale	Real estate available and held for sale— The Company reports real estate assets to be sold at the lower of their carrying amount or estimated fair value less costs to sell and classifies them as “Real estate available and held for sale” on the Company's consolidated balance sheets. If the estimated fair value less costs to sell is less than the carrying value, the difference will be recorded as an impairment charge. Impairment for real estate assets disposed of or classified as held for sale are included in "Impairment of assets" in the Company's consolidated statements of operations. Once a real estate asset is classified as held for sale, depreciation expense is no longer recorded. The Company classifies its real estate assets as held for sale in the period in which all of the following conditions are met: (i) the Company commits to a plan and has the authority to sell the asset; (ii) the asset is available for sale in its current condition; (iii) the Company has initiated an active marketing plan to locate a buyer for the asset; (iv) the sale of the asset is both probable and expected to qualify for full sales recognition within a period of 12 months; (v) the asset is being actively marketed for sale at a price that is reflective of its current fair value; and (vi) the Company does not anticipate changes to its plan to sell the asset.
Net investment in Leases and Interest Income from Sales-Type Leases	Net Investment in Leases —Net investment in leases are recognized when the Company's leases qualify as sales-type leases. The net investment in leases is initially measured at the present value of the fixed and determinable lease payments, including any guaranteed or unguaranteed residual value of the asset at the end of the lease, discounted at the rate implicit in the lease. If a lease qualifies as a sales-type lease, it is further evaluated to determine whether the transaction is considered a sale leaseback transaction. If the sales-type lease does not qualify as a sale leaseback transaction, the lease is considered a financing receivable and is recognized in accordance with ASC 310 (refer to Note 5) and recorded in "Loans receivable and other lending investments, net" on the Company's consolidated balance sheets. Interest Income from Sales-Type Leases —Interest income from sales-type leases is recognized in "Interest income from sales-type leases" in the Company's consolidated statements of operations under the effective interest method. The effective interest method produces a constant yield on the net investment in the lease over the term of the lease. Rent payments that are not fixed and determinable at lease inception, such as percentage rent and CPI adjustments, are not included in the effective interest method calculation and are recognized in "Interest income from sales-type leases" in the Company's consolidated statements of operations in the period earned.
Deferred expenses and other assets and accounts payable, accrued expenses and other liabilities	Deferred expenses and other assets and accounts payable, accrued expenses and other liabilities— Effective January 1, 2019 with the adoption of ASU 2016-02, the Company, as lessee, records right-of-use lease assets in "Deferred expenses and other assets" and lease liabilities in "Accounts payable, accrued expenses and other liabilities" on its consolidated balance sheets for operating and finance leases, both measured at the present value of the lease payments. Some of the Company's lease agreements include extension options, which are not included in the lease payments unless the extensions are reasonably certain to be exercised.
