Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Refer to the Company’s 2017 Annual Report on Form 10-K for a summary of its significant accounting policies. Except as disclosed below, there have been no changes to the Company’s significant accounting policies in the six months ended June 30, 2018. Recently Adopted Accounting Pronouncements Effective January 1, 2018, the Company adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, on a modified retrospective basis. This new guidance replaces existing revenue recognition standards. The core principle of this standard is that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Substantially all of the Company’s revenue follows the existing leasing guidance and is not impacted by the adoption of this standard, however, the sale of investment property is required to follow the new guidance as well as ASU 2017-05, Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets discussed below. The sale of investment property is reported as “gain on sales of investment properties” in the accompanying condensed consolidated statements of operations and other comprehensive income (loss) and further discussed in Note 4 – Dispositions. The adoption of ASU 2014-09, Revenue from Contracts with Customers, did not have a material effect on the Company’s condensed consolidated financial statements as substantially all of its revenue falls outside of the scope of this guidance. Effective January 1, 2018, the Company adopted ASU 2017-05, Other Income–Gains and Losses from the Derecognition of Nonfinancial Assets, on a modified retrospective basis. This new pronouncement, which adds guidance for partial sales of nonfinancial assets and clarifies the scope of Subtopic 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets, applies to the derecognition of all nonfinancial assets (including real estate) for which the counterparty is not a customer. The sale of investment property is reported as “gain on sales of investment properties” in the accompanying condensed consolidated statements of operations and other comprehensive income (loss) and further discussed in Note 4 – Dispositions. The adoption of this pronouncement did not have a material effect on the Company’s condensed consolidated financial statements as the adoption of the new guidance did not result in a change to the timing or amount of gain recognized upon disposition as compared to the previous guidance. Effective January 1, 2018, the Company adopted ASU 2016-01, Financial Instruments – Overall, on a prospective basis. This new guidance requires companies to disclose the fair value of financial assets and financial liabilities measured at amortized cost in accordance with the exit price notion, which is consistent with the Company’s existing practices, and no longer requires disclosure of the methods and significant assumptions used, including any changes, to estimate fair value. In addition, companies are required to disclose all financial assets and financial liabilities grouped by (i) measurement category and (ii) form of financial instrument. The adoption of this pronouncement did not have a material effect on the Company’s condensed consolidated financial statements. The Company elected to early adopt ASU 2017-12, Derivatives and Hedging, as of January 1, 2018. This new guidance amends the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in an entity’s financial statements. It also eliminates the requirement to separately measure and report hedge ineffectiveness. Entities are now required to present the earnings effect of the hedging instrument in the same income statement line item in which they report the earnings effect of the hedged item. In addition, entities may perform the initial quantitative assessment of hedge effectiveness at any time after hedge designation, but no later than the first quarterly effectiveness testing date, and subsequent assessments of hedge effectiveness may be performed qualitatively unless facts and circumstances change. Disclosure requirements have been modified to include a tabular disclosure related to the effect of hedging instruments on the income statement and the requirement to disclose the ineffective portion of the change in fair value of such instruments has been eliminated. The adoption of this pronouncement resulted in a cumulative effect adjustment of $12 to accumulated other comprehensive income and accumulated distributions in excess of earnings related to eliminating the separate measurement of ineffectiveness. The amended presentation and disclosure guidance is required only prospectively. Recently Issued Accounting Pronouncements In June 2018, the Securities and Exchange Commission issued a final rule, Inline XBRL Filing of Tagged Data, which will require the use of the Inline eXtensible Business Reporting Language (XBRL) format for the submission of operating company financial statement information. In addition, the final rule will eliminate the requirement for operating companies to post “Interactive Data Files” (i.e., machine-readable computer code that presents information in XBRL format) on their websites. Large accelerated filers that prepare their financial statements in accordance with GAAP will be subject to Inline XBRL requirements beginning with the fiscal period ending on or after June 15, 2019. The Company expects to use Inline XBRL starting with its Form 10-Q for the quarter ending June 30, 2019. In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases. This new guidance is effective January 1, 2019, with early adoption permitted. The pronouncement will require lessees to recognize a liability to make lease payments and a right-of-use (ROU) asset, initially measured at the present value of lease payments, for both operating and financing leases. For leases with a term of 12 months or less, lessees will be permitted to make an accounting policy election by class of underlying asset to not recognize lease liabilities and lease assets. The guidance allows lessors to make an accounting policy election, by class of underlying asset, to not separate non-lease components from lease components, if certain requirements are met. The guidance also provides an optional transition method which would allow entities to initially apply the new guidance in the period of adoption, recognizing a cumulative-effect adjustment to the opening balance of retained earnings, if necessary. Upon adoption, the Company will recognize a lease liability and an ROU asset for operating leases where it is the lessee, such as ground leases and office leases. The Company is in the process of evaluating the inputs required to calculate the amounts that will be recorded on its balance sheet for each lease. For leases with a term of 12 months or less, the Company expects to make an accounting policy election by class of underlying asset to not recognize lease liabilities and lease assets. For leases where it is the lessor, the Company expects that accounting for lease components will be largely unchanged from existing GAAP and to elect the practical expedient to not separate non-lease components from lease components. Only incremental direct leasing costs may be capitalized under the new guidance, which is consistent with the Company’s existing policies. The Company expects to adopt this new guidance on January 1, 2019 and apply the requirements as of that date. The Company will continue to evaluate the impact of this guidance until it becomes effective, but the Company does not expect the guidance regarding capitalization of leasing costs will have any effect on its condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses. This new guidance is effective January 1, 2020, with early adoption permitted beginning January 1, 2019, and replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. Financial assets that are measured at amortized cost will be required to be presented at the net amount expected to be collected with an allowance for credit losses deducted from the amortized cost basis. In addition, an entity must consider broader information in developing its expected credit loss estimate, including the use of forecasted information. Generally, the pronouncement requires a modified retrospective method of adoption. The Company will continue to evaluate the impact of this guidance until it becomes effective.
