Accounting Policies [Abstract]
New Accounting Pronouncements	On January 1, 2016, the Company adopted Accounting Standards Update ("ASU") 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU 2015-03") which modified the presentation of 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 September 30, 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 August 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments ("ASU 2016-15") which was issued to reduce diversity in practice in how certain cash receipts and cash payments, including debt prepayment or debt extinguishment costs, distributions from equity method investees, and other separately identifiable cash flows, are presented and classified in the statement of cash flows. ASU 2016-15 is effective for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted. Management is evaluating the impact of the guidance on the Company's consolidated financial statements. 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. 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 evaluating the impact of the guidance on the Company's consolidated financial statements. In March 2016, the 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 does not believe the guidance will have a material impact 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. However, in certain instances a long-term lease of land could be classified as a sales-type lease, resulting in the lessor derecognizing the underlying asset from its books and recording a profit or loss on sale and the net investment in the lease. 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 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.
