The Company's primary business segments are real estate finance, land and development, net lease and operating properties (refer to Note 17 ). Organization —The Company began its business in 1993 through the management of private investment funds and became publicly traded in 1998. Since that time, the Company has grown through the origination of new investments, as well as through corporate acquisitions.

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, 2015 , as amended on Form 10-K/A on March 9, 2016 (the " 2015 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 consolidated financial statements and the related notes to conform to the 2016 presentation. During the year ended December 31, 2015, the Company determined that its classification of common shares repurchased under its share repurchase programs should be classified as a reduction to common stock for the par amount of the common stock repurchased and additional paid in capital and included as shares unissued within the consolidated financial statements. The Company previously classified common shares repurchased under its share repurchase programs as treasury stock. The misclassification eliminates treasury stock and results in corresponding reductions of common stock and additional paid-in capital, which results in no change in total equity within the consolidated balance sheets and consolidated statements of changes in equity. All repurchased shares previously reported as treasury stock will now be reported as unissued common stock. The change has no impact on the previously reported consolidated statements of operations, consolidated statements of comprehensive income or consolidated statements of cash flows. The Company evaluated the impact of this correction on previously issued financial statements and concluded they were not materially misstated. In order to conform previous financial statements with the current period, the Company elected to revise previously issued financial statements the next time such financial statements are filed. The accompanying consolidated statements of changes in equity balances as of March 31, 2015 have been revised as follows: As Reported Change As Adjusted (in thousands) March 31, 2015 Additional paid-in capital $ 4,007,540 $ (263,451 ) $ 3,744,089 Common stock 146 (61 ) 85 Treasury stock, at cost (263,512 ) 263,512 — Total 3,744,174 — 3,744,174 Principles of Consolidation —The consolidated financial statements include the financial statements of the Company, its wholly owned subsidiaries, controlled partnerships and variable interest entities ("VIEs") for which the Company is the primary beneficiary. All significant 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," "Earnings from equity method investments," "Real estate expense" and "Interest expense" in the Company's consolidated statements of operations. The Company has not provided 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. As of March 31, 2016 , the total assets of these consolidated VIEs were $351.4 million and total liabilities were $60.9 million . The classifications of these assets are primarily within "Land and development" and "Real estate, net" on the Company's consolidated balance sheets. The classifications of liabilities are primarily within "Accounts payable, accrued expenses and other liabilities" on the Company's consolidated balance sheets. 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, 2016. 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 March 31, 2016 , the Company's maximum exposure to loss from these investments does not exceed the sum of the $75.2 million carrying value of the investments, which are classified in "Other investments" on the Company's consolidated balance sheets, and $54.2 million of related unfunded commitments.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies In accordance with the adoption of Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03") the Company presents debt issuance costs as a deduction from the carrying value of "Debt obligations, net" and "Loan participations payable, net" on the Company's consolidated balance sheets, which is consistent with the presentation of debt discounts. These costs were previously recorded in "Deferred expenses and other assets, net" on the Company's consolidated balance sheets. As a result, as of December 31, 2015, "Deferred expenses and other assets, net" excludes $25.1 million of debt issuance costs and "Debt obligations, net" and "Loan participations payable, net" are presented net of debt issuance costs of $24.9 million and $0.2 million , respectively. Debt issuance costs associated with revolving-debt arrangements are recorded in "Deferred expenses and other assets, net" on the Company's consolidated balance sheets. On January 1, 2016, the Company adopted ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02") which modified the analysis it must perform to determine whether it should consolidate certain types of entities. The guidance does not amend the existing disclosure requirements for VIEs or voting interest entities ("VOEs"). The guidance, however, modified the requirements to qualify under the VOE model. The adoption did not have a material impact on the Company's consolidated financial statements. On January 1, 2016, the Company adopted ASU 2014-16, Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity ("ASU 2014-16") which eliminated the diversity in practice for the accounting for hybrid financial instruments issued in the form of a share. ASU 2014-16 requires management to consider all terms and features, whether stated or implied, of a hybrid instrument when determining whether the nature of the instrument is more akin to a debt instrument or an equity instrument. Embedded derivative features, which are accounted for separately from host contracts, should also be considered in the analysis of the hybrid instrument. The adoption did not have a material impact on the Company's consolidated financial statements. As of March 31, 2016 , the remainder of the Company's significant accounting policies, which are detailed in the Company's 2015 Annual Report, have not changed materially. New Accounting Pronouncements — In March 2016 , Financial Accounting Standards Board ("FASB") issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") which was issued to simplify several aspects of the accounting for share-based payment transactions, including income tax, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"), which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. For operating leases, a lessee will be required to do the following: (i) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position; (ii) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis and (iii) classify all cash payments within operating activities in the statement of cash flows. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"), which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern ("ASU 2014-15") which requires management to evaluate whether there is substantial doubt that the Company is able to continue operating as a going concern within one year after the date the financial statements are issued or available to be issued. If there is substantial doubt, additional disclosure is required, including the principal condition or event that raised the substantial doubt, the Company's evaluation of the condition or event in relation to its ability to meet its obligations and the Company's plan to alleviate (or, which is intended to alleviate) the substantial doubt. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. Management does not believe the guidance will have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09") which supersedes existing industry-specific guidance, including ASC 360-20, Real Estate Sales . The new standard is principles-based and requires more estimates and judgment than current guidance. Certain contracts with customers, including lease contracts and financial instruments and other contractual rights, are not within the scope of the new guidance. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date , to defer the effective date of ASU 2014-09 by one year. ASU 2014-09 is now effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted beginning January 1, 2017. Management is evaluating the impact of the guidance on the Company's consolidated financial statements.

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. An undrawn credit facility commitment fee ranges from 0.375% to 0.5% , based on average utilization each quarter.

Proceeds from the 2012 Secured Credit Facilities, together with cash on hand, were used to repurchase and repay other outstanding debt. The 2012 Secured Credit Facilities are collateralized by a first lien on a fixed pool of assets. Proceeds from principal repayments and sales of collateral are applied to amortize the 2012 Secured Credit Facilities. Proceeds received for interest, rent, lease payments and fee income are retained by the Company. The Company may also make optional prepayments, subject to prepayment fees. The 2012 Tranche A-1 Facility was fully repaid in August 2013. Additionally, through March 31, 2016 , the Company made cumulative amortization repayments of $144.9 million on the 2012 Tranche A-2 Facility. For the three months ended March 31, 2016 and 2015, repayments of the 2012 Tranche A-2 Facility prior to maturity resulted in losses on early extinguishment of debt of $0.1 million and $0.2 million , respectively, related to the accelerated amortization of discounts and unamortized deferred financing fees on the portion of the facility that was repaid. These amounts are included in "Loss on early extinguishment of debt, net" in the Company's consolidated statements of operations. Unsecured Notes —In March 2016, the Company repaid its $261.4 million principal amount of 5.875% senior unsecured notes at maturity using available cash. In addition, in March 2016 the Company issued $275.0 million principal amount of 6.50% senior unsecured notes due July 2021. Proceeds from the offering were used to repay $5.0 million of the 2015 Revolving Credit Facility, pay related financing costs and, subsequent to the end of the quarter, repay in full the $265.0 million principal amount of senior unsecured notes due July 2016. Encumbered/Unencumbered Assets —As of March 31, 2016 and December 31, 2015 , the carrying value of the Company's encumbered and unencumbered assets by asset type are as follows ($ in thousands): As of March 31, 2016 December 31, 2015 Encumbered Assets Unencumbered Assets Encumbered Assets Unencumbered Assets Real estate, net $ 806,550 $ 772,050 $ 816,721 $ 777,262 Real estate available and held for sale 13,047 119,348 10,593 126,681 Land and development 17,682 1,006,752 17,714 984,249 Loans receivable and other lending investments, net (1)(2) 157,347 1,361,735 170,162 1,314,823 Other investments 15,385 218,605 22,352 231,820 Cash and other assets — 885,372 — 1,008,415 Total $ 1,010,011 $ 4,363,862 $ 1,037,542 $ 4,443,250 _______________________________________________________________________________ (1) As of March 31, 2016 and December 31, 2015 , the amounts presented exclude general reserves for loan losses of $36.6 million and $36.0 million , respectively. (2) As of March 31, 2016 and December 31, 2015, the amount presented excludes loan participations of $154.9 million and $153.0 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 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. While the Company's ability to incur additional indebtedness under the fixed charge coverage ratio is currently 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 2012 Secured Credit Facilities and the 2015 Revolving Credit Facility contain certain covenants, including covenants relating to collateral coverage, dividend payments, 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 2012 Secured Credit Facilities require the Company to maintain collateral coverage of at least 1.25 x outstanding borrowings on the facilities. The 2015 Revolving Credit Facility is secured by a borrowing base of assets and requires the Company to maintain both collateral coverage 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 collateral coverage 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. In addition, for so long as the Company maintains its qualification as a REIT, the 2012 Secured Credit Facilities and the 2015 Revolving Credit Facility permit the Company to distribute 100% of its REIT taxable income on an annual basis (prior to deducting certain cumulative NOL carryforwards in the case of the 2015 Revolving Credit Facility). The Company may not pay common dividends if it ceases to qualify as a REIT. The Company's 2012 Secured Credit Facilities 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Unfunded Commitments —The Company generally funds construction and development loans and build-outs of space in net lease assets over a period of time if and when the borrowers and tenants meet established milestones and other performance criteria. The Company refers to these arrangements as Performance-Based Commitments. In addition, the Company sometimes establishes a maximum amount of additional funding which it will make available to a borrower or tenant for an expansion or addition to a project if it approves of the expansion or addition in its sole discretion. The Company refers to these arrangements as Discretionary Fundings. Finally, the Company has committed to invest capital in several real estate funds and other ventures. These arrangements are referred to as Strategic Investments. As of March 31, 2016 , the maximum amount of fundings the Company may be required to make under each category, assuming all performance hurdles and milestones are met under the Performance-Based Commitments, that it approves all Discretionary Fundings and that 100% of its capital committed to Strategic Investments is drawn down, are as follows ($ in thousands): Loans and Other Lending Investments Real Estate Other Investments Total Performance-Based Commitments $ 752,417 $ 17,161 $ 19,642 $ 789,220 Strategic Investments — — 45,978 45,978 Discretionary Fundings 5,000 — — 5,000 Total $ 757,417 $ 17,161 $ 65,620 $ 840,198 Legal Proceedings —The Company and/or one or more of its subsidiaries is party to various pending litigation matters that are considered ordinary routine litigation incidental to the Company's business as a finance and investment company focused on the commercial real estate industry, including loan foreclosure and foreclosure-related proceedings. In addition to such matters, the Company is a party to the following legal proceedings: On March 7, 2014, a shareholder action purporting to assert derivative, class and individual claims was filed in the Circuit Court for Baltimore City, Maryland naming the Company, a number of its current and former senior executives (including its chief executive officer) and current and former directors as defendants. The complaint sought unspecified damages and other relief and alleged breach of fiduciary duty, breach of contract and other causes of action arising out of shares of common stock issued by the Company to its senior executives pursuant to restricted stock unit awards granted in December 2008 and modified in July 2011. On October 30, 2014, the Circuit Court granted the defendants’ Motions to Dismiss and plaintiffs’ claims against all of the defendants in this action were dismissed. Plaintiffs appealed the Circuit Court's dismissal of their claims against the Company and all other defendants. On January 28, 2016, the Court of Special Appeals affirmed the order of the Circuit Court, holding that the Circuit Court properly dismissed plaintiffs' claims against all defendants, including the Company. On March 16, 2016, plaintiffs filed a petition for certiorari with the Maryland Court of Appeals, requesting that the Court of Appeals reverse the decision of the Court of Special Appeals. We have filed a response in opposition, arguing that the petition for certiorari should be denied. Action on the petition for certiorari is pending. On January 22, 2015, the United States District Court for the District of Maryland (the "Court") entered a judgment in favor of the Company in the matter of U.S. Home Corporation ("Lennar") v. Settlers Crossing, LLC, et al. (Civil Action No. DKC 08-1863). The litigation involved a dispute over the purchase and sale of approximately 1,250 acres of land in Prince George’s County, Maryland. The Court found that the Company was entitled to specific performance and awarded damages to it in the aggregate amount of: (i) the remaining purchase price to be paid by Lennar of $114.0 million ; plus (ii) interest on the unpaid amount at a rate of 12% per annum, calculated on a per diem basis, from May 27, 2008, until Lennar proceeds to settlement on the land; plus (iii) real estate taxes paid by the Company; plus (iv) actual and reasonable attorneys' fees and costs incurred by the Company in connection with the litigation. The Court ordered Lennar to proceed to settlement on the land and to pay the total amounts awarded to the Company within 30 days of the judgment. Lennar has appealed the Court's judgment. The Court has granted Lennar's motion to stay the judgment pending appeal, subject to Lennar posting a required appeal bond, which has been posted. The Court also clarified the judgment that the unpaid amount will accrue simple interest at a rate of 12% annually, including while the appeal is pending. In the pending appeal before the United States Court of Appeals for the Fourth Circuit, the parties have filed their respective briefs. Oral argument has not yet been scheduled. There can be no assurance as to the timing or actual receipt by the Company of amounts awarded by the Court or the outcome of any appeal. A third party is entitled to a 7.8% participation interest in all proceeds paid to the Company. On a quarterly basis, the Company evaluates developments in legal proceedings that could require a liability to be accrued and/or disclosed. Based on its current knowledge, and after consultation with legal counsel, the Company believes it is not a party to, nor are any of its properties the subject of, any pending legal proceeding that would have a material adverse effect on the Company's consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives The Company's use of derivative financial instruments is primarily 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. Derivatives not designated as hedges are not speculative and are used to manage the Company's exposure to interest rate movements, foreign exchange rate movements, and other identified risks, but may not meet the strict hedge accounting requirements. 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 March 31, 2016 and December 31, 2015 ($ in thousands): Derivative Assets as of Derivative Liabilities as of March 31, 2016 December 31, 2015 March 31, 2016 December 31, 2015 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives Designated in Hedging Relationships Foreign exchange contracts N/A $ — Other Assets $ 39 Other Liabilities $ 48 N/A $ — Interest rate swaps N/A — N/A — Other Liabilities 564 Other Liabilities 131 Total $ — $ 39 $ 612 $ 131 Derivatives not Designated in Hedging Relationships Foreign exchange contracts Other Assets $ 106 Other Assets $ 378 Other Liabilities $ 317 N/A $ — Interest rate cap Other Assets 301 Other Assets 1,105 N/A — N/A — Total $ 407 $ 1,483 $ 317 $ — The tables below present the effect of the Company's derivative financial instruments in the consolidated statements of operations and the consolidated statements of comprehensive income (loss) for the three months ended March 31, 2016 and 2015 ($ in thousands): Derivatives Designated in Hedging Relationships Location of Gain (Loss) Recognized in Income Amount of Gain (Loss) Recognized in Accumulated Other Comprehensive Income (Effective Portion) Amount of Gain (Loss) Reclassified from Accumulated Other Comprehensive Income into Earnings (Effective Portion) Amount of Gain (Loss) Reclassified from Accumulated Other Comprehensive Income into Earnings (Ineffective Portion) For the Three Months Ended March 31, 2016 Interest rate cap Interest Expense $ — $ (185 ) N/A Interest rate cap Earnings from equity method investments (1 ) — N/A Interest rate swaps Interest Expense (502 ) 25 N/A Interest rate swap Earnings from equity method investments (459 ) (97 ) N/A Foreign exchange contracts Earnings from equity method investments (87 ) — N/A For the Three Months Ended March 31, 2015 Interest rate cap Interest Expense — (77 ) N/A Interest rate cap Earnings from equity method investments (7 ) — N/A Interest rate swaps Interest Expense (376 ) 42 N/A Interest rate swap Earnings from equity method investments (364 ) (115 ) N/A Foreign exchange contracts Earnings from equity method investments (198 ) — N/A Amount of Gain (Loss) Recognized in Income Location of Gain (Loss) Recognized in Income For the Three Months Ended March 31, Derivatives not Designated in Hedging Relationships 2016 2015 Interest rate cap Other Expense $ (803 ) $ (2,036 ) Foreign exchange contracts Other Expense (182 ) 2,289 Foreign Exchange Contracts —The Company is exposed to fluctuations in foreign exchange rates on investments it holds in foreign entities. The Company uses foreign exchange contracts to hedge its exposure to changes in foreign exchange rates on its foreign investments. Foreign exchange contracts involve fixing the U.S. dollar ("USD") to the respective foreign currency exchange rate for delivery of a specified amount of foreign currency on a specified date. The foreign exchange contracts are typically cash settled in USD for their fair value at or close to their settlement date. For derivatives designated as net investment hedges, the effective portion of changes in the fair value of the derivatives are reported in Accumulated Other Comprehensive Income as part of the cumulative translation adjustment. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. Amounts are reclassified out of Accumulated Other Comprehensive Income into earnings when the hedged foreign entity is either sold or substantially liquidated. As of March 31, 2016 , the Company had the following outstanding foreign currency derivatives that were used to hedge its net investments in foreign operations that were designated ($ and Rs in thousands): Derivative Type Notional Amount Notional (USD Equivalent) Maturity Sells Indian rupee ("INR")/Buys USD Forward ₨ 456,000 $ 6,553 December 2016 For derivatives not designated as net investment hedges, the changes in the fair value of the derivatives are reported in the Company's consolidated statements of operations within "Other Expense."

The Company recorded net gains (losses) related to foreign investments of $0.1 million and $(0.1) million during the three months ended March 31, 2016 and 2015, respectively, in its consolidated statements of operations. Interest Rate Hedges —For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivatives are reported in Accumulated Other Comprehensive Income (Loss). The ineffective portion of the change in fair value of the derivatives is recognized directly in the Company's consolidated statements of operations. As of March 31, 2016 , the Company had the following outstanding interest rate swap that was used to hedge its variable rate debt that was designated as a cash flow hedge ($ in thousands): Derivative Type Notional Amount Variable Rate Fixed Rate Effective Date Maturity Interest rate swap $ 26,801 LIBOR + 2.00% 3.47% October 2012 November 2019 For derivatives not designated as cash flow hedges, the changes in the fair value of the derivatives are reported in the Company's consolidated statements of operations within "Other Expense."

Credit Risk-Related Contingent Features —The Company has agreements with each of its derivative counterparties that contain a provision where if the Company either defaults or is capable of being declared in default on any of its indebtedness, then the Company could also be declared in default on its derivative obligations. The Company reports derivative instruments on a gross basis in the consolidated financial statements. In connection with its foreign currency derivatives which were in a liability position as of March 31, 2016 and December 31, 2015 , the Company has posted collateral of $1.0 million as of both dates and is included in "Deferred expenses and other assets, net" on the Company's consolidated balance sheets.

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, 2014, the Company had $856.4 million of NOL carryforwards at the corporate REIT level that can generally be used to offset both ordinary and capital taxable income in future years and will expire through 2034 if unused. The amount of NOL carryforwards as of December 31, 2015 will be determined upon finalization of the Company's 2015 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 2012 Tranche A-2 Facility and 2015 Revolving Credit Facility permit the Company to distribute 100% of its REIT taxable income on an annual basis (prior to deducting certain cumulative NOL carryforwards in the case of the 2015 Revolving Credit Facility), for so long as the Company maintains its qualification as a REIT. The 2012 Tranche A-2 Facility and 2015 Revolving Credit Facility restrict the Company from paying any common dividends if it ceases to qualify as a REIT. The Company did not declare or pay any common stock dividends for the three months ended March 31, 2016 and 2015 . Stock Repurchase Program —In February 2016, after having substantially utilized the remaining availability previously authorized, the Company's Board of Directors authorized a new $50.0 million stock repurchase program. The program authorizes the repurchase of common stock from time to time in open market and privately negotiated purchases, including pursuant to one or more trading plans. During the three months ended March 31, 2016 , the Company repurchased 5.8 million shares of its outstanding common stock for $58.1 million , at an average cost of $9.94 per share. During the three months ended March 31, 2015, the Company repurchased 44,000 shares of its outstanding common stock for $0.6 million , at an average cost of $12.66 per share. As of March 31, 2016 and December 31, 2015, the Company had remaining authorization to repurchase up to $40.6 million and $48.7 million , respectively, of common stock under its stock repurchase program. Accumulated Other Comprehensive Income (Loss) —"Accumulated other comprehensive income (loss)" reflected in the Company's shareholders' equity is comprised of the following ($ in thousands): As of March 31, 2016 December 31, 2015 Unrealized gains (losses) on available-for-sale securities $ (106 ) $ (125 ) Unrealized gains (losses) on cash flow hedges (1,433 ) (690 ) Unrealized losses on cumulative translation adjustment (4,038 ) (4,036 ) Accumulated other comprehensive income (loss) $ (5,577 ) $ (4,851 )

Disclosure of Compensation Related Costs, Share-based Payments [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 of $4.6 million and $3.2 million for the three months ended March 31, 2016 and 2015, respectively, in "General and administrative" in the Company's consolidated statements of operations. As of March 31, 2016 , there was $2.7 million of total unrecognized compensation cost related to all unvested restricted stock units ("Units") that are expected to be recognized over a weighted average remaining vesting/service period of 1.77 years. Performance Incentive Plans —The Company's Performance Incentive Plan ("iPIP") is 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 plan. The fair value of points is determined using a model that forecasts the Company's projected investment performance. iPIP is a liability-classified award which will be remeasured each reporting period at fair value until the awards are settled. The following is a summary of granted iPIP points. • In May 2014, the Company granted 73 iPIP points in the initial 2013-2014 investment pool. • In January 2015, the Company granted an additional 10 iPIP points in the 2013-2014 investment pool and 34 iPIP points in the 2015-2016 investment pool. • In January 2016, the Company granted an additional 10 iPIP points in the 2013-2014 investment pool and an additional 40 iPIP points in the 2015-2016 investment pool. As of March 31, 2016 and December 31, 2015, the Company had accrued compensation costs relating to iPIP of $19.6 million and $16.6 million , respectively, which are included in "Accounts payable, accrued expenses and other liabilities" on the Company's consolidated balance sheets. Long-Term Incentive Plan —The Company's shareholders approved the Company's 2009 Long-Term Incentive Plan (the "2009 LTIP") which is designed to provide incentive compensation for officers, key employees, directors and advisors of the Company. The 2009 LTIP provides for awards of stock options, shares of restricted stock, phantom shares, restricted stock units, dividend equivalent rights and other share-based performance awards. All awards under the 2009 LTIP are made at the discretion of the Company's Board of Directors or a committee of the Board of Directors. As of March 31, 2016 , an aggregate of 3.6 million shares remain available for issuance pursuant to future awards under the Company's 2009 Long-Term Incentive Plan. The Company's 2007 Incentive Compensation Plan ("Incentive Plan") was approved and adopted by the Company's Board of Directors in 2007 in order to establish performance goals for selected officers and other key employees and to determine bonuses that will be awarded to those officers and other key employees based on the extent to which they achieve those performance goals. Equity-based awards may be made under the Incentive Plan, subject to the terms of the Company's equity incentive plans. Restricted Share Issuances —During the three months ended March 31, 2016 , the Company granted 92,057 shares of common stock to certain employees under the 2009 LTIP as part of annual incentive awards that included a mix of cash and equity awards. The shares are fully-vested and 58,667 shares were issued net of statutory minimum required tax withholdings. The employees are restricted from selling these shares for up to 18 months from the date of grant. 2016 Restricted Stock Unit Activity —During the three months ended March 31, 2016 , the Company granted new stock-based compensation awards to certain employees in the form of long-term incentive awards, comprised of the following: • 122,817 service-based Units were granted on January 29, 2016, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest. The Units will cliff vest in one installment on December 31, 2018, if the employee remains employed by the Company on the vesting date, subject to certain accelerated vesting rights. Dividends will accrue as and when dividends are declared by the Company on shares of its common stock, but will not be paid unless and until the Units vest and are settled. As of March 31, 2016 , 122,817 of such service-based Units were outstanding. As of March 31, 2016 , the Company had the following additional stock-based compensation awards outstanding: • 48,519 target amount of performance-based Units were granted on January 30, 2015, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest. The performance is based on the Company's TSR, measured over a performance period ending on December 31, 2017, which is the date the awards cliff vest. Vesting will range from 0% to 200% of the target amount of the awards, depending on the Company’s TSR performance relative to the NAREIT All REITs Index (one-half of the target amount of the award) and the Russell 2000 Index (one-half of the target amount of the award) during the performance period. The Company, as well as any companies not included in each index at the beginning and end of the performance period, are excluded from calculation of the performance of such index. To the extent Units vest based on the Company's TSR performance, holders will receive an equivalent number of shares of common stock (after deducting shares for minimum required statutory withholdings), if the employee remains employed by the Company on the vesting date, subject to certain accelerated vesting rights. Dividends will accrue as and when dividends are declared by the Company on shares of its common stock, but will not be paid unless and until the Units vest and are settled. The fair values of the performance-based Units were determined by utilizing a Monte Carlo model to simulate a range of possible future stock prices for the Company's common stock. The assumptions used to estimate the fair value of these performance-based awards were 0.75% for risk-free interest rate and 28.14% for expected stock price volatility. • 61,557 service-based Units were granted on January 30, 2015, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest. The Units will cliff vest in one installment on December 31, 2017, if the employee remains employed by the Company on the vesting date, subject to certain accelerated vesting rights. Dividends will accrue as and when dividends are declared by the Company on shares of its common stock, but will not be paid unless and until the Units vest and are settled. • 49,434 target amount of performance-based Units, granted on January 10, 2014, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest based on the Company’s TSR measured over a performance period ending on December 31, 2016, which is the date the awards cliff vest. The other terms of these performance-based Units are identical to the terms described above for the performance-based Units granted in 2015. The fair values of the performance-based Units were determined by utilizing a Monte Carlo model to simulate a range of possible future stock prices for the Company's common stock. The assumptions used to estimate the fair value of these performance-based awards were 0.76% for risk-free interest rate and 44.84% for expected stock price volatility. • 62,662 service-based Units, granted on January 10, 2014, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest. The Units will cliff vest in one installment on December 31, 2016, if the employee remains employed by the Company on the vesting date, subject to certain accelerated vesting rights. Dividends will accrue as and when dividends are declared by the Company on shares of its common stock, but will not be paid unless and until the Units vest and are settled. • 8,751 service-based Units granted on various dates, representing the right to receive an equivalent number of shares of the Company's common stock (after deducting shares for minimum required statutory withholdings) if and when the Units vest. The Units have an original vesting term of three years. Upon vesting of these Units, holders will receive shares of the Company's common stock in the amount of the vested Units, net of statutory minimum required tax withholdings. Dividends will accrue as and when dividends are declared by the Company on shares of its common stock, but will not be paid unless and until the Units vest and are settled. Directors' Awards —As of March 31, 2016 , a combined total of 296,755 CSEs and restricted shares of common stock granted to members of the Company's Board of Directors remained outstanding under the Company's Non-Employee Directors Deferral Plan, with an aggregate intrinsic value of $2.9 million . 401(k) Plan —The Company made gross contributions of $0.6 million for each of the three months ended March 31, 2016 and 2015.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Earnings per share ("EPS") is calculated using the two-class method, which allocates earnings among common stock and participating securities to calculate EPS when an entity's capital structure includes either two or more classes of common stock or common stock and participating securities. HPU holders were current and former Company employees who purchased high performance common stock units under the Company's High Performance Unit Program. These HPU units were treated as a separate class of common stock. All of the Company's outstanding HPUs were repurchased and retired on August 13, 2015. The following table presents a reconciliation of income (loss) from continuing operations used in the basic and diluted EPS calculations ($ in thousands, except for per share data): For the Three Months Ended March 31, 2016 2015 Income (loss) from continuing operations $ (19,757 ) $ (33,469 ) Income from sales of real estate 10,458 21,156 Net (income) loss attributable to noncontrolling interests 942 1,841 Preferred dividends (12,830 ) (12,830 ) Income (loss) from continuing operations attributable to iStar Inc. and allocable to common shareholders, HPU holders and Participating Security Holders for basic earnings per common share $ (21,187 ) $ (23,302 ) For the Three Months Ended March 31, 2016 2015 Earnings allocable to common shares: Numerator for basic and diluted earnings per share: Income (loss) from continuing operations attributable to iStar Inc. and allocable to common shareholders $ (21,187 ) $ (22,553 ) Denominator for basic and diluted earnings per share: Weighted average common shares outstanding for basic and diluted earnings per common share 77,060 85,497 Basic and diluted earnings per common share: Net income (loss) attributable to iStar Inc. and allocable to common shareholders $ (0.27 ) $ (0.26 ) For the Three Months Ended March 31, 2016 2015 Earnings allocable to High Performance Units (1) : Numerator for basic and diluted earnings per HPU share: Net income (loss) attributable to iStar Inc. and allocable to HPU holders $ — $ (749 ) Denominator for basic and diluted earnings per HPU share: Weighted average High Performance Units outstanding for basic and diluted earnings per share — 15 Basic and diluted earnings per HPU share: Net income (loss) attributable to iStar Inc. and allocable to HPU holders $ — $ (49.93 ) _______________________________________________________________________________ (1) All of the Company's outstanding HPUs were repurchased and retired on August 13, 2015.

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 March 31, 2016 Recurring basis: Derivative assets (1) $ 407 $ — $ 407 $ — Derivative liabilities (1) 929 — 929 — Available-for-sale securities (1) 5,536 — — 5,536 Non-recurring basis: Impaired loans (2) 5,200 — — 5,200 As of December 31, 2015 Recurring basis: Derivative assets (1) $ 1,522 $ — $ 1,522 $ — Derivative liabilities (1) 131 — 131 — Available-for-sale securities (1) 1,161 — — 1,161 Non-recurring basis: Impaired loans (3) 3,200 — — 3,200 ____________________________________________________________ (1) The fair value of the Company's derivatives and available-for-sale securities are based upon third-party broker quotes. During the three months ended March 31, 2016, the Company acquired $4.4 million of available for sale securities. There were no other material changes in Level 3 assets and there were no transfers into/out of Level 3 for the three months ended March 31, 2016. (2) The Company recorded a provision for loan losses on one loan with a fair value of $5.2 million using an appraisal based on market comparable sales. (3) The Company recorded a provision for loan losses on one loan with a fair value of $3.2 million based on a discounted cash flow analysis using a discount rate of 14.3% . Fair values of financial instruments— The Company's estimated fair values of its loans receivable and other lending investments and outstanding debt was $1.7 billion and $4.3 billion , respectively, as of March 31, 2016 and $1.6 billion and $4.3 billion , respectively, as of December 31, 2015 . 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 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, are included in the fair value hierarchy table above.

Summary of Significant Accoun28

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
New accounting pronouncements	In accordance with the adoption of Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03") the Company presents debt issuance costs as a deduction from the carrying value of "Debt obligations, net" and "Loan participations payable, net" on the Company's consolidated balance sheets, which is consistent with the presentation of debt discounts. These costs were previously recorded in "Deferred expenses and other assets, net" on the Company's consolidated balance sheets. As a result, as of December 31, 2015, "Deferred expenses and other assets, net" excludes $25.1 million of debt issuance costs and "Debt obligations, net" and "Loan participations payable, net" are presented net of debt issuance costs of $24.9 million and $0.2 million , respectively. Debt issuance costs associated with revolving-debt arrangements are recorded in "Deferred expenses and other assets, net" on the Company's consolidated balance sheets. On January 1, 2016, the Company adopted ASU 2015-02, Amendments to the Consolidation Analysis ("ASU 2015-02") which modified the analysis it must perform to determine whether it should consolidate certain types of entities. The guidance does not amend the existing disclosure requirements for VIEs or voting interest entities ("VOEs"). The guidance, however, modified the requirements to qualify under the VOE model. The adoption did not have a material impact on the Company's consolidated financial statements. On January 1, 2016, the Company adopted ASU 2014-16, Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share is More Akin to Debt or to Equity ("ASU 2014-16") which eliminated the diversity in practice for the accounting for hybrid financial instruments issued in the form of a share. ASU 2014-16 requires management to consider all terms and features, whether stated or implied, of a hybrid instrument when determining whether the nature of the instrument is more akin to a debt instrument or an equity instrument. Embedded derivative features, which are accounted for separately from host contracts, should also be considered in the analysis of the hybrid instrument. The adoption did not have a material impact on the Company's consolidated financial statements. As of March 31, 2016 , the remainder of the Company's significant accounting policies, which are detailed in the Company's 2015 Annual Report, have not changed materially. New Accounting Pronouncements — In March 2016 , Financial Accounting Standards Board ("FASB") issued ASU 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting ("ASU 2016-09") which was issued to simplify several aspects of the accounting for share-based payment transactions, including income tax, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases ("ASU 2016-02"), which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases. For operating leases, a lessee will be required to do the following: (i) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position; (ii) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis and (iii) classify all cash payments within operating activities in the statement of cash flows. The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. ASU 2016-02 is effective for interim and annual reporting periods beginning after December 15, 2018. Early adoption is permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities ("ASU 2016-01"), which addresses certain aspects of recognition, measurement, presentation and disclosure of financial instruments. ASU 2016-01 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is not permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern ("ASU 2014-15") which requires management to evaluate whether there is substantial doubt that the Company is able to continue operating as a going concern within one year after the date the financial statements are issued or available to be issued. If there is substantial doubt, additional disclosure is required, including the principal condition or event that raised the substantial doubt, the Company's evaluation of the condition or event in relation to its ability to meet its obligations and the Company's plan to alleviate (or, which is intended to alleviate) the substantial doubt. ASU 2014-15 is effective for interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted. Management does not believe the guidance will have a material impact on the Company's consolidated financial statements. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("ASU 2014-09") which supersedes existing industry-specific guidance, including ASC 360-20, Real Estate Sales . The new standard is principles-based and requires more estimates and judgment than current guidance. Certain contracts with customers, including lease contracts and financial instruments and other contractual rights, are not within the scope of the new guidance. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers - Deferral of the Effective Date , to defer the effective date of ASU 2014-09 by one year. ASU 2014-09 is now effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted beginning January 1, 2017. Management is evaluating the impact of the guidance on the Company's consolidated financial statements.
