Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the financial position and results of operations of the Company and its consolidated subsidiaries, including the Operating Partnership, its wholly-owned subsidiaries, and any interests in variable interest entities ("VIEs") where the Company has been determined to be the primary beneficiary. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year, particularly in light of the novel coronavirus ("COVID-19") pandemic and its effects on the domestic and global economies. The pandemic has led governments and other authorities around the world, including federal, state and local authorities in the United States, to impose measures intended to control its spread, including restrictions on freedom of movement and business operations such as travel bans, border closings, business closures, quarantines and shelter-in-place orders, causing many of the Company’s tenants, particularly in the Company’s retail portfolio, to suspend or limit operations. We expect to continue to experience effects on our business as the impacts from COVID-19 and the related responses continue to develop. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current, and expected events and economic conditions. Actual results could differ significantly from management’s estimates. Reclassifications Certain items have been reclassified from their prior year classifications to conform to the current year presentation. These reclassifications had no effect on net income or stockholders' equity as previously reported. Recent Accounting Pronouncements Accounting Standards Adopted in 2020 Credit losses In June 2016, the Financial Accounting Standard Board ("FASB") issued ASU 2016-13, Financial Instruments - Credit Losses - Measurement of Credit Losses on Financial Instruments (Topic 326). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the "incurred loss" approach under previous guidance with an "expected loss" model for instruments measured at amortized cost, such as the Company's notes receivable, construction receivables, and off-balance sheet credit exposures. The amendment requires entities to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. The Company adopted the new standard on January 1, 2020, using the modified retrospective transition method and recorded a noncash cumulative effect adjustment to record a reduction to retained earnings of $3.0 million, $2.8 million of which relates to the Company's mezzanine loans and $0.2 million of which relates to the Company's construction accounts receivable. See Note 6—Notes Receivable and Current Expected Credit Losses, for more information. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement - Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820). The ASU is part of the FASB's disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by generally accepted accounting principles. The ASU modifies disclosure requirements on fair value measurements in Topic 820. The Company adopted the new standard on January 1, 2020. Adoption of the ASU did not have a material impact on disclosures in the Company's consolidated financial statements. See Note 12—Fair Value of Financial Instruments, for more information on the Company's presentation of the fair value of financial instruments. Pending Accounting Guidance Lease Modification Accounting Q&A In April 2020, the FASB staff issued a question and answer document (the "Lease Modification Q&A") focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows lessors, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Company is evaluating the Lease Modification Q&A. Other Accounting Policies See the Company's Annual Report on Form 10-K for the year ended December 31, 2019 for a description of other accounting principles upon which basis the accompanying consolidated financial statements were prepared.
