General
Basis of Presentation	We have prepared consolidated financial statements included herein without audit and in the opinion of management have included all adjustments necessary for a fair presentation of the consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (or SEC). Certain information and note disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (or GAAP) have been condensed or omitted pursuant to rules and regulations governing the presentation of interim financial statements. The accompanying consolidated financial statements include the accounts of our company and its wholly-owned subsidiaries.
Reclassifications	All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three months ended March 31, 2018 and 2017 are not necessarily indicative of the results for a full year.
Income taxes	No provision has been made for federal or state income taxes. Our company qualifies as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended. As such, we generally are not taxed on income that is distributed to our stockholders.
New Accounting Pronouncement	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (or FASB) issued Accounting Standards Update (or ASU) 2014-09, Revenue from Contracts with Customers, which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 states 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.” While this ASU specifically references contracts with customers, it may apply to certain other transactions such as the sale of real estate. Additionally, the FASB has issued targeted updates to clarify specific implementation issues of ASU 2014-09. These updates include ASU 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10, Identifying Performance Obligations and Licensing, and ASU 2016-12, Narrow-Scope Improvements and Practical Expedients. The new standard and its amendments are effective on January 1, 2018, and permit reporting entities to apply the standard using either a modified retrospective approach, by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption or full retrospective approach. We have assessed our revenue streams to identify any differences in the timing, measurement or presentation of revenue recognition. We have evaluated the provisions of ASU 2014-09 and its related updates and closely monitored developments and additional guidance to determine the potential impact of the new standard. We have concluded that adoption of this standard does not have an impact on our results of operations or financial condition, as our revenue consists of rental income from leasing arrangements and interest income from loan arrangements, both of which are specifically excluded from ASU 2014-09. We adopted this standard using the modified retrospective adoption method on January 1, 2018. In February 2016, the FASB issued ASU No. 2016-02 (or ASU 2016-02), Leases (Topic 842). The objective of this ASU is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. ASU 2016-02 modifies existing guidance by requiring lessees to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance of operating leases. ASU 2016-02 requires the lessors to identify lease and non-lease components of a lease agreement. ASU 2016-02 will govern the recognition of revenue for lease components. Revenue related to non-lease components under lease agreements will be subject to the revenue recognition standard, upon adoption of this ASU. Entities are required to use a modified retrospective approach for leases that exist or are entered into after January 1, 2017, the beginning of the earliest comparative period presented in the 2019 consolidated financial statements with a cumulative adjustment to the opening balance of retained earnings. In January 2018, the FASB proposed to amend ASU 2016-02 allowing the lessors, as a practical expedient, an election to not separate the non-lease components from the related lease components and instead, to account for those components as a single lease component (if certain criteria are met). The practical expedient option is available as a single election that must be consistently applied to all existing leases at the date of adoption. Furthermore, in March 2018, the FASB agreed to issue an amendment to ASU 2016-02 that would provide an entity the optional transition method to make January 1, 2019, the initial application date of the ASU, rather than January 1, 2017. Consequently, entities that elect both the practical expedient and the optional transitional method will apply the new lease ASU prospectively to leases commencing or modified after January 1, 2019, and will not be required to apply the disclosures under the new lease ASU to comparative periods. Consistent with present standards, we will continue to account for lease revenue on a straight-line basis when applicable. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We have begun our process for implementing this guidance, including identifying any non-lease components in our lease arrangements. We will continue to evaluate this guidance and the impact to us, as both lessor and lessee, on our consolidated financial statements. In August 2016, FASB issued ASU No. 2016-15 (or ASU 2016-15), Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (A Consensus of the Emerging Issues Task Force). ASU 2016-15 provides guidance that reduces the diversity in practice of the classification of certain cash receipts and cash payments within the statement of cash flows. This guidance is effective for fiscal periods beginning after December 15, 2017. We adopted this standard on January 1, 2018. The adoption of this guidance did not have a material impact on our financial statements. In January 2017, the FASB issued ASU No. 2017-01(or ASU 2017-01), Business Combinations (Topic 805): Clarifying Definition of a Business. ASU 2017-01 clarifies the framework for determining whether an integrated set of assets and activities meets the definition of a business. The revised framework establishes a screen for determining whether an integrated set of assets and activities is a business and narrows the definition of a business, which is expected to result in fewer transactions being accounted for as business combinations. Acquisitions of integrated sets of assets and activities that do not meet the definition of a business are accounted for as asset acquisitions. This update is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted for transactions that have not been reported in previously issued (or available to be issued) financial statements. We adopted ASU 2017-01 during the second quarter of 2017. Historically, our acquisitions qualified as either a business combination or asset acquisition. The adoption of this ASU did not have a material impact on the company’s results of operations or financial condition as most of our acquisitions of investment properties will continue to qualify as asset acquisitions. In February 2017, the FASB issued ASU No. 2017-05 (or ASU 2017-05), Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets. ASU 2017-05 defines an in-substance nonfinancial asset and clarifies guidance related to partial sales of nonfinancial assets. This standard is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017. The adoption of this ASU did not have a material impact on the consolidated financial statements and related notes. .
