Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	1. ORGANIZATION AND DESCRIPTION OF BUSINESS: GTJ REIT, Inc. (the “Company” or “GTJ REIT”) was incorporated on June 26, 2006, under the Maryland General Corporation Law. The Company is focused primarily on the acquisition, ownership, management, and operation of commercial real estate located in New York, New Jersey, Connecticut and Delaware. The Company has elected to be treated as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended (the “Code”) and elected December 31 as its fiscal year end. Under the REIT operating structure, the Company is permitted to deduct the dividends paid to its stockholders when determining its taxable income. Assuming dividends equal or exceed the Company’s taxable income, the Company generally will not be required to pay federal corporate income taxes on such income. On January 17, 2013, the Company closed on a transaction with Wu/Lighthouse Portfolio, LLC, in which a limited partnership (the “Operating Partnership”) owned and controlled by the Company, acquired all outstanding ownership interests of a portfolio consisting of 25 commercial properties (the “Acquired Properties”) located in New York, New Jersey and Connecticut, in exchange for 33.29% of the outstanding limited partnership interest in the Operating Partnership. The outstanding limited partnership interest in the Operating Partnership exchanged for the Acquired Properties was increased to 33.78% due to post-closing adjustments, and to 34.48% due to the redemption of certain shares of GTJ REIT, Inc. common stock. The acquisition was recorded as a business combination and, accordingly, the purchase price was allocated to the assets acquired and liabilities assumed at fair value. As a result of this acquisition and the subsequent acquisition of seventeen properties and the sale of one property from 2014 through 2018, the Company currently beneficially owns a 65.52% interest in a total of 48 properties consisting of approximately 5.8 million square feet of primarily industrial properties on approximately 389 acres of land in New York, New Jersey, Connecticut and Delaware. At December 31, 2018, subject to certain anti-dilutive and other provisions contained in the governing agreements, the limited partnership interest in the Operating Partnership may be converted in the aggregate, into approximately 1.9 million shares of the Company’s common stock and approximately 5.2 million shares of the Company’s Series B preferred stock. We formerly owned a group of outdoor maintenance businesses, an electrical contracting business, and a parking garage business, which are presented as part of our consolidated financial statements. During 2011, the Board voted to divest these operations which were sold in 2012 and 2013.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Presentation: The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the financial statements of the Company, its wholly owned subsidiaries, and the Operating Partnership, as the Company makes all operating and financial decisions for (i.e., exercises control over) the Operating Partnership. All material intercompany transactions have been eliminated in consolidation. The ownership interests of the other investors in the Operating Partnership are recorded as noncontrolling interests. The Company has determined that redemptions of Company shares result in a reallocation between the Operating Partnership’s non-controlling interest (“OP NCI”) and Additional Paid-in-Capital (“APIC”). For the year ended December 31, 2018, the Company decreased its APIC with an offsetting increase to OP NCI of approximately $0.2 million. Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations. Use of Estimates: The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. All of these estimates reflect management’s best judgment about current economic and market conditions and their effects based on information available as of the date of these consolidated financial statements. If such conditions persist longer or deteriorate further than expected, it is reasonably possible that the judgments and estimates could change, which may result in impairments of certain assets. Significant estimates include the useful lives of long- lived assets including property, equipment and intangible assets, impairment of assets, collectability of receivables, contingencies, stock-based compensation, and fair value of assets and liabilities acquired in business combinations. Real Estate: Real estate assets are stated at cost, less accumulated depreciation and amortization. All costs related to the improvement or replacement of real estate properties are capitalized. Additions, renovations, and improvements that enhance and/or extend the useful life of a property are also capitalized. Expenditures for ordinary maintenance, repairs, and improvements that do not materially prolong the normal useful life of an asset, are charged to operations as incurred. The Company capitalizes all direct costs of real estate under development until the end of the development period. In addition, the Company capitalizes the indirect cost of insurance and real estate taxes allocable to real estate under development during the development period. The Company also capitalizes interest using the avoided cost method for real estate under development during the development period. The Company will cease the capitalization of these costs when development activities are substantially completed and the property is available for occupancy by tenants, but no later than one year from the completion of major construction activity at which time the property is placed in service and depreciation commences. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of these costs until activities are resumed. Real estate under development was $2.6 million and $5.6 million as of December 31, 2018 and 2017, respectively, and is included in buildings and improvements on the Company’s balance sheet. Upon the acquisition of real estate properties, the fair value of the real estate purchased is allocated to the acquired tangible assets (generally consisting of land, buildings and building improvements, and tenant improvements) and identified intangible assets and liabilities (generally consisting of above-market and below-market leases and the origination value of in-place leases) in accordance with GAAP. We utilize methods similar to those used by independent appraisers in estimating the fair value of acquired assets and liabilities. The fair value of the tangible assets of an acquired property considers the value of the property “as-if-vacant.” In allocating the purchase price to identified intangible assets and liabilities of an acquired property, the value of above-market and below-market leases is estimated based on the differences between contractual rentals and the estimated market rents over the applicable lease term discounted back to the date of acquisition utilizing a discount rate adjusted for the credit risk associated with the respective tenants. The aggregate value of in-place leases is measured based on the avoided costs associated with lack of revenue over a market oriented lease-up period, the avoided leasing commissions, and other avoided costs common in similar leasing transactions. Mortgage notes payable assumed in connection with acquisitions are recorded at their fair value using current market interest rates for similar debt at the time of acquisitions. Acquisition-related costs are expensed as incurred. The capitalized above-market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases and the capitalized below-market lease values are amortized as an increase to rental revenue over the remaining term of the respective leases. The value of in-place leases is based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors considered include estimates of carrying costs during expected lease-up periods, current market conditions, and costs to execute similar leases. The values of in-place leases are amortized over the remaining term of the respective leases. If a tenant vacates its space prior to its contractual expiration date, any unamortized balance of the related intangible assets or liabilities is recorded as income or expense in the period. The total net impact to rental revenues due to the amortization of above-market and below-market leases was a net increase in rental revenue of approximately $0.6 million and $0.4 million for the years ended December 31, 2018 and December 31, 2017, respectively. As of December 31, 2018, approximately $1.1 million and $10.9 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheets. As of December 31, 2017, approximately $1.4 million and $13.1 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheets. As of December 31, 2018 and 2017, approximately $5.0 million and $5.9 million (net of accumulated amortization), respectively, relating to below-market leases is included in acquired lease intangible liabilities, net in the accompanying consolidated balance sheets. The following table presents the projected increase to rental revenue from the amortization of the acquired above-market and below-market lease intangibles and the increase to amortization expense of the in-place lease intangibles for properties owned at December 31, 2018, over the next five years and thereafter (in thousands): Increase to Net amortization rental revenues expense 2019 $ 560 $ 1,955 2020 660 1,627 2021 510 1,400 2022 533 1,344 2023 635 1,189 Thereafter 974 3,345 $ 3,872 $ 10,860 Depreciation and Amortization: The Company uses the straight-line method for depreciation and amortization. Properties and property improvements are depreciated over their estimated useful lives, which range from 5 to 40 years. Furniture, fixtures, and equipment are depreciated over estimated useful lives that range from 5 to 10 years. Tenant improvements are amortized over the shorter of the remaining non-cancellable term of the related leases or their useful lives. Deferred Charges: Deferred charges consist principally of leasing commissions, which are amortized over the life of the related tenant leases, and financing costs, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets. If leases are terminated, the unamortized charges are expensed. Asset Impairment: Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability is based on an estimate of the undiscounted future cash flows that are expected to result from the real estate investment’s use and eventual disposition. Such cash flow analyses consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Management is required to make subjective assessments as to whether there are impairments in the value of the Company’s real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period that the assessment is made. Management has determined that, based upon the demolition of its property located at 35 Executive Boulevard, Orange, Connecticut, and plans to construct a 41,000 square foot industrial building, an accelerated depreciation of $7.5 million should be recorded during 2018. Management has determined that there were no indicators of impairment relating to its remaining long-lived assets at December 31, 2018. Reportable Segments: As of December 31, 2018, the Company primarily operated in one reportable segment, commercial real estate. Revenue Recognition: Rental income includes the base rent that each tenant is required to pay in accordance with the terms of their respective leases reported on a straight-line basis over the term of the lease. In order for management to determine, in its judgment, that the unbilled rent receivable applicable to each specific property is collectible, management reviews billed and unbilled rent receivables on a quarterly basis and takes into consideration the tenant’s payment history and financial condition. Some of the leases provide for additional contingent rental revenue in the form of percentage rents and increases based on the consumer price index, subject to certain maximums and minimums. Substantially all of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay for its pro rata share of real estate taxes, insurance, and ordinary maintenance and repairs for the property. Property operating expense recoveries from tenants of common area maintenance, real estate taxes, and other recoverable costs are recognized as revenues in the period that the related expenses are incurred. Earnings Per Share Information: The Company presents both basic and diluted earnings per share. Basic earnings per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, where such exercise or conversion would result in a lower per share amount. Restricted stock was included in the computation of basic and diluted earnings per share. Stock option awards were included in the computation of diluted earnings per share in 2018 and 2017 because the option awards were dilutive. Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted Cash: Restricted cash includes a construction bond and reserves used to pay real estate taxes, insurance, repairs, leasing costs and capital improvements. Fair Value Measurement: The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) 820-10-05 for financial assets and liabilities. This standard defines fair value, provides guidance for measuring fair value and requires certain disclosures. Fair value is defined as 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. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities disclosed at fair values are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are defined by ASC 820-10-35, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment, and the Company evaluates its hierarchy disclosures each quarter. The three-tier fair value hierarchy is as follows: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting management’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Income Taxes: The Company is organized and conducts its operations to qualify as a REIT for Federal income tax purposes. Accordingly, the Company is generally not subject to Federal income taxation on the portion of its distributable income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its REIT taxable income to its stockholders and complies with certain other requirements as defined in the Code. The Company also participates in certain activities conducted by entities which elected to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal, state, and local taxes on the income from these activities. The Company accounts for income taxes under the asset and liability method as required by the provisions of ASC 740-10-30. Under this method, deferred tax assets and liabilities are established based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance for deferred tax assets for which it does not consider realization of such assets to be more likely than not. ASC 740-10-65 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10-65, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. ASC 740-10-65 also provides guidance on de-recognition, classification, interest and penalties on income taxes, accounting in interim periods and requires increased disclosures. As of December 31, 2018 and 2017, the Company had determined that no liabilities are required in connection with unrecognized tax positions. As of December 31, 2018, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service. Any interest and penalties would be expensed as incurred. The recently enacted Tax Cuts and Jobs Act (the “Act”) is a complex revision to the U.S. federal income tax laws with impacts on different categories of taxpayers and industries, and will require subsequent rulemaking and interpretation in a number of areas. The Act may impact certain of our tenants’ operating results, financial condition, and future business plans. There can be no assurance that the Act will not impact our operating results, financial condition, and future business operations. Concentrations of Credit Risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, which from time-to-time exceed the federal depository insurance coverage. Beginning January 1, 2013, all noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit insurance amount of $250,000. Management believes that the Company is not exposed to any significant credit risk due to the credit worthiness of the financial institutions. Contractual rent of $9.7 million, derived from five leases with the City of New York, represented 22% of the Company’s total contractual rental income for the years ended December 31, 2018 and 2017, respectively. Stock-Based Compensation: The Company has a stock-based compensation plan, which is described below in Note 6. The Company accounts for stock-based compensation in accordance with ASC 718, which establishes accounting for stock-based awards. Under the provisions of ASC 718, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is expensed at the grant date (for the portion that vests immediately) or ratably over the respective vesting periods. New Accounting Pronouncements: Lease Accounting In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “Leases (Topic No. 842).” ASU 2016-02 requires lessees to recognize, at the commencement date, a lease liability for all leases with a term greater than 12 months, which is the lessee’s obligation to make lease payments arising from a lease and measure it on a discounted basis. A lessee must also recognize an asset representing the lessee’s right to use a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new lease accounting permits companies to utilize certain practical expedients in the implementation of the new standard. The Company intends to utilize a package of three practical expedients that must be elected together for all leases and includes, (i) not reassessing expired or existing contracts as to whether they are or contain leases; (ii) not reassessing lease classification of existing leases; and (iii) not reassessing the amount of capitalized initial direct costs for existing leases. ASU 2016-02 also specifies that upon adoption, lessors will no longer be able to capitalize and amortize certain leasing related costs and instead will only be permitted to capitalize and amortize incremental direct leasing costs. As a result, we have concluded that subsequent to adoption, there will be no change in the capitalization of costs as compared to what we have historically capitalized. ASU 2016-02 initially provided for one retrospective transition method for lessors; however, a second transition method was subsequently provided by ASU 2018-11 as described below. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements,” which amended ASU 2016-02 to provide entities with an additional optional transition method to adopt ASU 2016-02. ASU 2018-11 simplifies transition requirements and, for lessors, provides a practical expedient for the separation of non-lease components from lease components. Specifically, ASU 2018-11 provides an option to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in the financial statements. In addition, ASU 2018-11 provides a practical expedient, by class of underlying asset, that permits lessors to make a policy election not to separate non-lease components from the associated lease component, and, instead, to account for those components as a single component if the non-lease components would otherwise be accounted for under the new revenue guidance (Topic 606). If certain conditions are met, the single component will be accounted for under either Topic 842 or Topic 606 depending on which component(s) are predominant. In July 2018, the FASB issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases.” These amendments provide clarifications and corrections to ASU 2016-02, Leases (Topic 842). In December 2018, the FASB issued ASU No. 2018-20, “Leases, (Topic 842): Narrow-Scope Improvements for Lessors”. These amendments clarify or simplify certain narrow aspects of ASC 842 for lessors. This ASU modifies ASU No. 2016-02 to permit lessors, as an accounting policy election, not to evaluate whether certain sales taxes and other similar taxes are lessor costs or lessee costs. Instead, those lessors will account for those costs as if they are lessee costs. Consequently, a lessor making this election will exclude from the consideration in the contract and from variable payments not included in the consideration in the contract all collections from lessees of taxes within the scope of the election and will provide certain disclosures (the accounting policy election includes sales, use, value added, and some excise taxes but excludes real estate taxes). The Company has elected not to evaluate whether the aforementioned costs are lessor or lessee costs. This ASU also provides that certain lessor costs require lessors to exclude from variable payments, and therefore revenue, specifically lessor costs paid by lessees directly to third parties. The amendments also require lessors to account for costs excluded from the consideration of a contract that are paid by the lessor and reimbursed by the lessee as variable payments. A lessor will record those reimbursed costs as revenue. The adoption of ASU 2018-20 will not have a material impact on the Company’s consolidated financial statements. ASU 2016-02 is effective for fiscal periods and interim periods within those fiscal periods beginning after December 15, 2018. Early adoption is permitted. The Company will adopt ASU 2016-02 (as amended by subsequent ASUs) effective January 1, 2019 utilizing the new transition method described in ASU 2018-11 and the package of three practical expedients provided by ASU 2016-02 as described above. The Company anticipates that all of its leases will continue to be classified as operating leases and the adoption of ASU 2016-02 will not have a material impact on revenues. The Company intends to utilize the practical expedient related to the separation of lease and non-lease components provided by ASU 2018-11. The Company has determined that the effect of electing this lessor practical expedient is that revenues related to leases will be reported on one line in the presentation within the statement of income. The timing of revenue recognition is expected to be the same for the majority of the Company’s new leases as compared to similar existing leases. As lessee, the Company intends to utilize the practical expedients in the implementation of ASU 2016-02 related to not separating non-lease components from the associated lease component. As lessee, the Company is a party to an office lease with future lease obligations aggregating to $568 thousand as of December 31, 2018, for which the Company expects to record right-of-use assets and corresponding lease liabilities at the present value of the remaining minimum rental payments upon the adoption of ASU 2016-02. Other Accounting Topics In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements.” These amendments provide clarifications and corrections to certain ASC subtopics including the following: 220-10 (Income Statement – Reporting Comprehensive Income – Overall), 470-50 (Debt – Modifications and Extinguishments), 480-10 (Distinguishing Liabilities from Equity – Overall), 718-740 (Compensation – Stock Compensation – Income Taxes), 805-740 (Business Combinations – Income Taxes), 815-10 (Derivatives and Hedging – Overall), and 820-10 (Fair Value Measurement – Overall). Some of the amendments in ASU 2018-09 do not require transition guidance and are effective upon issuance; however, many of the amendments do not have transition guidance with effective dates for annual periods beginning after December 15, 2018. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718) – Improvements to Nonemployee Share-Based Payment Accounting.” These amendments provide specific guidance for transactions for acquiring goods and services from nonemployees and specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. This guidance is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted but not earlier than the adoption of Topic 606. The Company does not believe that this guidance will have a material effect on its consolidated financial statements as it has not historically issued share-based payments in exchange for goods or services to be consumed within its operations. In March 2018, the FASB issued ASU No. 2018-05, “Income Taxes (Topic 740) – Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118”, which allowed public companies to record provisional amounts in earnings for the year ended December 31, 2017 due to the complexities involved in accounting for the enactment of the Tax Cuts and Jobs Act. ASU 2018-05 was effective upon issuance. The Company did not recognize any estimated income tax effects of the Tax Cuts and Jobs Act in its 2017 consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 118. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) - Scope of Modification Accounting.” ASU 2017-09 clarifies Topic 718 such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (a) the fair value of the modified award is the same as the fair value of the original award immediately before the modification, (b) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification, and (c) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The amendments are effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The adoption of ASU 2017-09 did not have a material impact on the Company’s consolidated financial statements. In February 2017, the FASB issued ASU No. 2017-05, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 was issued to clarify the scope of Subtopic 610-20 and to add guidance for partial sales of nonfinancial assets, including partial sales of real estate. ASU 2017-05 clarifies the scope of Subtopic 610-20 by defining the term “in substance nonfinancial asset.” If substantially all of the fair value of the assets (recognized and unrecognized) promised to a counterparty in a contract is concentrated in nonfinancial assets, a financial asset in the same arrangement would still be considered part of an “in substance nonfinancial asset”. Additionally, ASU 2017-05 indicates an entity should identify each distinct nonfinancial asset (e.g., real estate and inventory) or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it. ASU 2017-05 requires an entity to derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when two criteria are met: 1) the entity does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with Topic 810, and 2) the entity transfers control of the asset in accordance with Topic 606. The effective date and transition requirements of ASU 2017-05 are the same as Topic 606. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within those periods. The adoption of ASU 2017-05 did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) - Clarifying the Definition of a Business.” ASU 2017-01 provides new guidance that changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets is not a business. ASU 2017-01 also requires a business to include at least one substantive process. ASU 2017-01 is effective for public business entities for fiscal years beginning after December 15, 2017 and has been adopted by the Company effective January 1, 2018. It is expected that the standard will reduce the number of future real estate acquisitions accounted for as a business combination and therefore, reduce the amount of acquisition costs that will be expensed. The adoption of ASU 2017-01 will result in a reduction of expensed acquisition costs and a corresponding increase to net income. There were no acquisitions during the year ended December 31, 2018. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230) - Restricted Cash.” ASU 2016-18 updates Topic 230 to require cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts on the statement of cash flows. Consequently, transfers between cash and restricted cash will not be presented as

People’s United Bank Loan Agreement: In connection with the acquisition in 2014 of an 84,000 square foot parking lot in Long Island City, Queens, NY, a wholly owned subsidiary of the Operating Partnership entered into a mortgage loan agreement with People’s United Bank in the aggregate amount of $15.5 million. The loan has a ten-year term and bears interest at 4.18%. Payments for the first seven years are interest only. Payments over the remaining three years of the term are based on a 25-year amortization schedule, with a balloon payment of $14.4 million due at maturity. American International Group Loan Agreement: On February 20, 2015 (the “Closing Date”), the Operating Partnership refinanced the current outstanding debt on certain properties and placed new financing on others by entering into a loan agreement (the “AIG Loan Agreement”) with American General Life Insurance Company, the Variable Life Insurance Company, The United States Life Insurance Company in the City of New York, American Home Assurance Company and Commerce and Industry Insurance Company. The AIG Loan Agreement provides a secured loan in the principal amount of $233.1 million (the “AIG Loan”). The AIG Loan is a 10-year term loan that requires interest only payments at the rate of 4.05% per annum. During the period from April 1, 2015, to February 1, 2025, payments of interest only will be payable in arrears with the entire principal balance plus any accrued and unpaid interest due and payable on March 1, 2025. The Operating Partnership’s obligation to pay the interest, principal and other amounts under the Loan Agreement are evidenced by the secured promissory notes executed on the Closing Date (the “AIG Notes”). The AIG Notes are secured by certain mortgages encumbering 28 properties in New York, New Jersey and Connecticut. Allstate Life Insurance Company Loan Agreement: On March 13, 2015, in connection with the acquisition of six properties in Piscataway, NJ, the Operating Partnership closed on a $39.1 million cross-collateralized mortgage (the “Allstate Loan”) from Allstate Life Insurance Company, Allstate Life Insurance Company of New York and American Heritage Life Insurance Company. The Allstate Loan Agreement provided a secured facility with a 10-year term loan. During the first three years of the term of the loan, it required interest only payments at the rate of 4% per annum. Following this period until the loan matures on April 1, 2025, payments will be based on a 30-year amortization schedule. United States Life Insurance Company Loan Agreement: On December 20, 2017, (the “Closing Date”) four wholly owned subsidiaries of the Operating Partnership (collectively, the “U.S. Life Borrowers”) entered in a loan agreement (the “U.S. Life Loan Agreement”) with the United States Life Insurance Company in the City of New York (the “Lender”). The U.S. Life Loan Agreement provides for a secured loan facility in the principal amount of $39.0 million (the “Loan Facility”). The Loan Facility is a 10-year term loan that requires interest only payments at the rate of 3.82% per annum. During the period from February 1, 2018 to December 1, 2027, payments of interest only on the principal balance of the Note (as defined below) will be payable in arrears, with the entire principal balance due and payable on January 1, 2028, the loan maturity date. Subject to certain conditions, the U.S Life Borrowers may prepay the outstanding loan amount in whole on or after January 1, 2023, by providing advance notice of the prepayment to the Lender and remitting a prepayment premium equal to the greater of 1% of the then outstanding principal amount of the Loan Facility or the then present value of the Note. The U.S Life Borrowers paid the Lender a one-time application fee of $50,000 in connection with the Loan Facility. The U.S. Life Borrowers’ obligation to pay the principal, interest and other amounts under the Loan Facility are evidenced by the secured promissory note executed by the U.S. Life Borrowers as of the Closing Date (the “Note”). The Note is secured by certain mortgages encumbering the U.S Life Borrowers’ properties (a total of four properties) located in New York, New Jersey and Delaware. In the event of default, the initial rate of interest on the Note will increase to the greatest of (i) 18% per annum, (ii) a per annum rate equal to 4% over the prime established rate, or (iii) a per annum rate equal to 5% over the original interest rate, all subject to the applicable state or federal laws. The Note contains other terms and provisions that are customary for instruments of this nature. Approximately $37.5 million from the loan proceeds were used to reduce the Company’s obligation under its secured revolving credit facility with Key Bank. United States Life Insurance Company Loan Agreement: On March 21, 2018, four wholly owned subsidiaries of the Operating Partnership refinanced the current outstanding debt on certain properties by entering into a loan agreement with the United States Life Insurance Company in the City of New York. The loan agreement provides for a secured loan facility in the principal amount of $33.0 million. The loan facility is a ten-year term loan that requires interest only payments at the rate of 4.25% per annum on the principal balance for the first five (5) years of the term and principal and interest payments (amortized over a 30-year period) during the second five (5) years of the term.

Secured Revolving Credit Facility	12 Months Ended

Line Of Credit Facility [Abstract]
Secured Revolving Credit Facility	5. SECURED REVOLVING CREDIT FACILITY: Key Bank Loan Agreement : On December 2, 2015, the Operating Partnership entered into a Credit Agreement (the “Credit Agreement”) with Keybank National Association and Keybanc Capital Markets Inc., as lead arranger (collectively, “Key Bank”). The Credit Agreement contemplated a $50.0 million revolving line of credit facility, with an initial term of two years, with a one-year extension option, subject to certain other customary conditions. Loans drawn down by the Operating Partnership under the facility will need to specify, at the Operating Partnership’s option, whether they are Base Rate loans or LIBOR Rate loans. The Base Rate loans initially bore a base rate of interest calculated as the greater of: (a) the fluctuating annual rate of interest announced from time to time by Key Bank as its “prime rate,” (b) 0.5% above the rate announced by the Federal Reserve Bank of Cleveland (or Federal Funds Effective Rate), or (c) LIBOR plus 100 basis points (bps). The LIBOR Rate loans initially bore interest at a rate of LIBOR rate plus 300 to 350 bps, depending upon the overall leverage of the properties. Each revolving credit loan under the facility will be evidenced by separate promissory note(s). The Operating Partnership agreed to pay to Key Bank a facility unused fee in the amount calculated as 0.30% for usage less than 50% and 0.20% for usage 50% or greater, calculated as a per diem rate, multiplied by the excess of the total commitment over the outstanding principal amount of the loans under the facility at the time of the calculation. Key Bank has the right to reduce the amount of loan commitments under the facility provided, among other things, they give an advance written notice of such reductions and that in no event the total commitment under the facility is less than $25.0 million. The Operating Partnership may at its option convert any of the revolving credit loans into a revolving credit loan of another type which loan will then bear interest as a base rate loan or a LIBOR rate loan, subject to certain conversion conditions. In addition, Key Bank also agreed to extend, from time to time, as the Operating Partnership may request, upon an advance written notice, swing loans in the total amount not to exceed $5.0 million. Such loans, if and when extended, will also be evidenced by separate promissory note(s). Due to the revolving nature of the facility, amounts prepaid under the facility may be borrowed again. The Credit Agreement contemplates (i) mandatory prepayments by the Operating Partnership of any borrowings under the facility in excess of the total allowable commitment, among other events, and (ii) optional prepayments, without any penalty or premium, in whole or in part, subject to payments of any amounts due associated with the prepayment of LIBOR rate contracts. The Operating Partnership’s obligations under the facility are secured by a first priority lien and security interest to be held by the agents for Key Bank, in certain of the property, rights and interests of the Operating Partnership, the Guarantors (as defined below) and their subsidiaries now existing and as may be acquired (collectively, the “Collateral”). GTJ REIT, Inc., GTJ GP, LLC, and each party to the Guaranty are collectively referred to as the “Guarantors.” The parties to the Credit Agreement also entered into several side agreements, including, the Joinder Agreements, the Assignment of Interests, the Acknowledgments, the Mortgages, the Guaranty, and other agreements and instruments to facilitate the transactions contemplated under the Credit Agreement. Such agreements contain terms and provisions that are customary for instruments of this nature. The Operating Partnership’s continuing ability to borrow under the facility will be subject to its ongoing compliance with various affirmative and negative covenants, including, among others, with respect to liquidity, minimum occupancy, total indebtedness and minimum net worth. The Credit Agreement contains events of default and remedies customary for loan transactions of this sort including, among others, those related to a default in the payment of principal or interest, a material inaccuracy of a representation or warranty, and a default with regard to performance of certain covenants. The Credit Agreement includes customary representations and warranties of the Operating Partnership which must continue to be true and correct in all material respects as a condition to future draws. In addition, the Credit Agreement also includes customary events of default (in certain cases subject to customary cure), in the event of which, amounts outstanding under the facility may be accelerated. On July 27, 2017, the Operating Partnership increased its secured line of credit facility with Key Bank from $50.0 million to $88.0 million. The $38.0 million increase could only be used for the acquisition of certain properties specified in the second amendment to the Key Bank Credit Agreement (including earnest money deposits) and the payment of customary closing costs. In addition, the maturity date under the Credit Agreement was extended from December 1, 2017 to February 28, 2018, with an additional extension option to June 30, 2019, subject to the satisfaction of certain conditions. On December 20, 2017, the Operating Partnership refinanced certain properties acquired with its secured line of credit facility with Key Bank. As of result, the secured line of credit facility with Key Bank was reduced to $50.5 million, with the excess over $50.0 million only available for the purchase of a specified property. On February 27, 2018, the Operating Partnership increased its secured line of credit facility with Key Bank from $50.5 million to $55.0 million. In addition, the Operating Partnership exercised its option to extend the maturity date of the secured revolving line of credit facility with Key Bank to June 30, 2019. On July 31, 2018, the Operating Partnership reduced its line of credit facility with Key Bank from $55.0 million to $50.0 million. In addition, the maturity date of the secured revolving credit facility with Key Bank was extended from June 30, 2019 to June 30, 2020 and the applicable margin for LIBOR rate loans and base rate loans applicable to the secured revolving credit facility with Key Bank was reduced by 50 basis points (bps). The base rate loans will bear a base rate of interest calculated as the greater of: (a) the fluctuating annual rate of interest announced from time to time by Key Bank as its “prime rate,” (b) 50 bps above the rate announced by the Federal Reserve Bank of Cleveland (or Federal Funds Effective Rate), or (c) LIBOR plus 100 bps. The LIBOR rate loans will bear interest at a rate of LIBOR plus 250 to 300 bps, depending upon the overall leverage of the properties. The contemplated uses of proceeds under the Credit Agreement include, among others, repayment of indebtedness, funding of acquisitions, development and capital improvements, as well as working capital expenditures. Outstanding borrowings under the secured revolving credit facility with Key Bank as of December 31, 2018 and December 31, 2017 were $40.0 million and $35.9 million, respectively, which are considered LIBOR Rate loans. In connection with the Credit Agreement, the Operating Partnership is required to comply with certain covenants. As of December 31, 2018, the Operating Partnership was in compliance with all covenants.

In order to qualify as a REIT, the Company must distribute at least 90% of its taxable income and must distribute 100% of its taxable income in order not to be subject to corporate federal income taxes on retained income. The Company anticipates it will distribute all of its taxable income to its stockholders. Because taxable income differs from cash flow from operations due to non-cash revenues or expenses (such as depreciation), in certain circumstances, the Company may generate operating cash flow in excess of its distributions or, alternatively, may be required to borrow to make sufficient distribution payments. Stock Based Compensation: On June 11, 2007, the Board of Directors approved the Company’s 2007 Incentive Award Plan (the “2007 Plan”). The 2007 Plan covered directors, officers, key employees and consultants of the Company. The purposes of the 2007 Plan was to further the growth, development, and financial success of the Company and to obtain and retain the services of the individuals considered essential to the long-term success of the Company. The 2007 Plan provided for awards in the form of restricted shares, incentive stock options, non-qualified stock options and stock appreciation rights. The aggregate number of shares of common stock which may have been awarded under the 2007 Plan was 1,000,000 shares. The 2007 Plan expired by its terms on June 11, 2017. The 2017 Incentive Award Plan (the “2017 Plan”) was adopted by the Board and became effective on April 24, 2017, subject to the approval of the Company’s stockholders which was obtained on June 8, 2017. The 2017 Plan has intended purposes to further the growth, development, and financial success of the Company and to obtain and retain the services of those individuals considered essential to the long-term success of the Company. The 2017 Plan provides for awards in the form of stock, stock units, incentive stock options, non-qualified stock options and stock appreciation rights. The aggregate number of shares of common stock which may be awarded under the 2017 Plan is 2,000,000 shares. As of December 31, 2018, the Company had 1,942,062 shares available for future issuance under the 2017 Plan. Dividends paid on restricted shares are recorded as dividends on shares of the Company’s common stock whether or not they are vested. In accordance with ASC 718-10-35, the Company measures the compensation costs for these shares as of the date of the grant and the expense is recognized in earnings, at the grant date (for the portion that vest immediately) and then ratably over the respective vesting periods. On February 7, 2008, 55,000 options were granted to non-employee directors and vested immediately and 200,000 options were granted to key officers of the Company and had a three year vesting period. On June 9, 2011, the Company granted 10,000 options to a non-employee director which vested immediately. On November 8, 2016, 200,000 options were granted to key officers of the Company and had a three-year vesting period. In 2017, 200,000 options were exercised. All options expire ten years from the date of grant.

Related Party Transactions	8. RELATED PARTY TRANSACTIONS: Paul Cooper, the Chairman and Chief Executive Officer of the Company, and Louis Sheinker, the President, Secretary and Chief Operating Officer of the Company, each hold passive, minority ownership interests in a real estate brokerage firm, The Rochlin Organization. The firm acted as the exclusive broker for one of the Company’s properties. In 2013, the firm introduced a new tenant to the property, resulting in the execution of a lease agreement and a subsequent lease modification. The firm earned aggregate brokerage cash commissions of approximately $60,000 based on a total lease value of $1,015,000. In January 2014, the new tenant expanded further which resulted in approximately $95,000 of brokerage commissions on the additional lease modification value of $2,100,000. In November 2015, the tenant concluded negotiations to expand by an additional 35,000 square feet which resulted in approximately $12,000 of brokerage commissions on the additional lease modification value of $200,000. In December 2016, the tenant concluded negotiations to expand by an additional 35,000 square feet which resulted in approximately $10,000 of brokerage commissions on the additional lease modification value of $332,000. In March 2018, the tenant exercised its option to renew its lease for the premises resulting in approximately $107,000 of brokerage commissions on the additional lease modification value of $3,600,000 which are unpaid at December 31, 2018 and included in accounts payable and accrued expenses on the Company’s consolidated balance sheet. In November 2018, the tenant concluded negotiations to expand by an additional 30,000 square feet which resulted in approximately $40,000 of brokerage commissions on the additional lease modification value of $670,000 which are unpaid at December 31, 2018 and included in other liabilities on the Company’s consolidated balance sheet. The Company’s executive and administrative offices, located at 60 Hempstead Avenue, West Hempstead, New York, are being leased from Lighthouse Sixty, L.P., a partnership of which Paul Cooper and Louis Sheinker are managing members of the general partner. The lease agreement expires in 2020 and has a current annual base rent of approximately $279,000 with aggregate lease payments totaling $1.8 million. On November 4, 2014, the Company invested $1.8 million for a limited partnership interest in Garden 1101 Stewart, L.P. (“Garden 1101”). Garden 1101 was formed for the purposes of acquiring a 90,000 square foot office building in Garden City, NY that was converted to a medical office building. The general partner of Garden 1101 is partially owned by Paul Cooper and Louis Sheinker. The investment is included in investment in unconsolidated affiliate on the consolidated balance sheets. On February 9, 2018, the property acquired by Garden 1101 was sold and the Company received a distribution from the partnership of $3.7 million which resulted in a realized gain from unconsolidated affiliate of $2.5 million in 2018. An unrealized loss of approximately $198,000 is included in losses of unconsolidated affiliate on the consolidated statement of operations for the year ended December 31, 2017.

Fair Value Disclosures [Abstract]
Fair Value	10. FAIR VALUE: Fair Value of Financial Instruments: The fair value of the Company’s financial instruments is determined based upon applicable accounting guidance. Fair value is defined as 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 guidance requires disclosure of the level within the fair value hierarchy in which the fair value measurements fall, including measurements using quoted prices in active markets for identical assets or liabilities (Level 1), quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active (Level 2), and significant valuation assumptions that are not readily observable in the market (Level 3). The fair values of cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued expenses and secured revolving credit facility approximated their carrying value because of the short-term nature based on Level 1 inputs. The fair values of mortgage notes payable and pension withdrawal liability are based on borrowing rates available to the Company, which are Level 2 inputs. The following table summarizes the carrying values and the estimated fair values of the financial instruments (in thousands): December 31, 2018 December 31, 2017 Carrying Estimated Carrying Estimated Value Value Value Value Financial assets: Cash and cash equivalents $ 21,175 $ 21,175 $ 8,423 $ 8,423 Restricted cash 3,895 3,895 3,471 3,471 Accounts receivable 415 415 159 159 Financial liabilities: Accounts payable and accrued expenses $ 4,417 $ 4,417 $ 3,608 $ 3,608 Secured revolving credit facility 40,000 40,000 35,857 35,857 Mortgage notes payable 367,415 358,949 376,523 371,920 Pension withdrawal liability 1,065 1,054 1,131 1,139

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	12. INCOME TAXES: The Company elected to be taxed as a REIT under the Code. A REIT will generally not be subject to federal income taxation on that portion of its income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its taxable income to its stockholders and complies with certain other requirements. It is management’s intention to adhere to these requirements and maintain the Company’s REIT status. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable minimum tax and may not be able to qualify as a REIT for four subsequent taxable years). Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries are subject to federal, state, and local income taxes. The recently enacted Tax Cuts and Jobs Act (the “Act”) is a complex revision to the U.S. federal income tax laws with impacts on different categories of taxpayers and industries, and will require subsequent rulemaking and interpretation in a number of areas. The Act may impact certain of our tenants’ operating results, financial condition, and future business plans. There can be no assurance that the Act will not impact our operating results, financial condition, and future business operations. Income from “qualified dividends” payable to U.S. stockholders that are individuals, trusts and estates are generally subject to tax at preferential rates. Dividends payable by REITs, however, generally are not eligible for the preferential tax rates applicable to qualified dividend income. Although these rules do not adversely affect the taxation of REITs or dividends payable by REITs, to the extent that the preferential rates continue to apply to regular corporate qualified dividends, investors who are individuals, trusts and estates may perceive investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could materially and adversely affect the value of the shares of REITs, including the value of our common stock. The Act signed into law by the President on December 22, 2017 makes significant changes to the Code, including changes that impact REITs and their shareholders, among others. In particular, the Act reduces the maximum corporate tax rate from 35% to 21%. In addition, for tax years beginning before January 1, 2026, the Act permits up to a 20% deduction for individuals, trusts, and estates with respect to their receipt of “qualified REIT dividends”, which are dividends from a REIT that are not capital gain dividends and are not qualified dividend income. This provides closer parity between the treatment under the new law of ordinary REIT dividends and qualified dividends. These changes generally result in an effective maximum U.S. federal income tax rate on such dividends of 29.6%, if the deduction is allowed in full. However, by reducing the corporate tax rate, it is possible that the Act will nevertheless reduce the relative attractiveness to investors (as compared with potential alternative investments) of the generally single level of taxation on REIT distributions. Key provisions of the Act that could impact us and the value of our shares include the following: • temporarily reducing individual U.S. federal income tax rates on ordinary income; the highest individual U.S. federal income tax rate is reduced from 39.6% to 37% (through tax years beginning before January 1, 2026), while eliminating miscellaneous itemized deductions and limiting state and local tax deductions; • reducing the maximum corporate income tax rate from 35% to 21%, which reduces, but does not eliminate, the competitive advantage that REITs enjoy relative to non-REIT corporations; • permitting (subject to certain limitations) a deduction for certain pass-through business income, including, as noted above, dividends received by our stockholders that are not designated by us as capital gain dividends or qualified dividend income, which will allow individuals, trusts, and estates to deduct up to 20% of such amounts, generally resulting in an effective maximum U.S. federal income tax rate of 29.6% on such dividends, if the deduction is allowed in full (through tax years beginning before January 1, 2026); • reducing the highest rate of withholding with respect to our distributions to non-U.S. stockholders that are treated as attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%; • limiting our deduction for net operating losses to 80% of taxable income (prior to the application of the dividends paid deduction), where taxable income is determined without regarding to the net operating loss deduction itself, and generally eliminating net operating loss carrybacks and allowing unused net operating losses to be carried forward indefinitely; • amending the limitation on the deduction of net interest expense for all businesses, other than certain electing real estate businesses (which could adversely affect any of our taxable REIT subsidiaries (each, a “TRS”), including any new TRS that we may form); • expanding the ability of businesses to deduct the cost of certain purchases of property in the year in which such property is purchased; and • eliminating the corporate alternative minimum tax. The rules dealing with federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Department of the Treasury. Changes to the tax laws, with or without retroactive application, could adversely affect our stockholders or us. We cannot predict how changes in the tax laws might affect our stockholders or us. New legislation, Treasury Regulations, administrative interpretations or court decisions could significantly and negatively affect our ability to qualify as a REIT or the federal income tax consequences of such qualification. Reconciliation between GAAP Income From Continuing Operations and Federal Taxable Income: The following table reconciles GAAP income from continuing operations to taxable income for the years ended December 31, 2018 and 2017 (in thousands): 2018 2017 Net income from operations $ 2,432 $ 3,596 GAAP net (income) loss of taxable subsidiaries (637 ) 23 GAAP net income from REIT operations 1,795 3,619 Operating expense book deductions greater than tax 998 1,417 Book depreciation in excess of tax depreciation 6,860 5,204 GAAP amortization of intangibles in excess of tax amortization 1,721 1,981 Straightline rent adjustments (874 ) (468 ) Acquisition costs capitalized for tax - 398 Gain on sale of real estate (4,577 ) - Write down of carrying value relating to demolished property 7,489 - (Income) allocable to noncontrolling interest (6,658 ) (5,682 ) Estimated taxable income subject to the dividend requirement $ 6,754 $ 6,469 We have determined for income tax purposes that the 2018 regular dividends were considered both ordinary dividends and capital gain distributions and the 2017 regular dividends were considered ordinary dividends. The total distributions paid in 2018 were the result of cash flow from operations and investing activities. The total distributions paid in 2017 were the result of cash flow from operations. Taxable REIT Subsidiaries: The Company is subject to federal, state, and local income taxes on the income from its Taxable REIT subsidiaries (“TRS”) activities, which include all the discontinued operations of Shelter Express, Inc. and subsidiaries. There were no provisions for (benefit from) income taxes from discontinued operations for the years ended December 31, 2018 and 2017. The TRS entities have approximately $20.0 million of net operating loss carry-forwards at December 31, 2018. The Company has recorded a full valuation allowable against the deferred income tax assets as it does not consider realization of such assets to be more likely than not. The Company has determined that any changes in the value of the deferred income tax assets would have no impact on the Company’s consolidated financial statements inasmuch as it would be offset by a full valuation allowance.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the financial statements of the Company, its wholly owned subsidiaries, and the Operating Partnership, as the Company makes all operating and financial decisions for (i.e., exercises control over) the Operating Partnership. All material intercompany transactions have been eliminated in consolidation. The ownership interests of the other investors in the Operating Partnership are recorded as noncontrolling interests. The Company has determined that redemptions of Company shares result in a reallocation between the Operating Partnership’s non-controlling interest (“OP NCI”) and Additional Paid-in-Capital (“APIC”). For the year ended December 31, 2018, the Company decreased its APIC with an offsetting increase to OP NCI of approximately $0.2 million. Certain prior year amounts have been reclassified for consistency with the current year presentation. These reclassifications had no effect on the reported results of operations.
Use of Estimates	Use of Estimates: The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. All of these estimates reflect management’s best judgment about current economic and market conditions and their effects based on information available as of the date of these consolidated financial statements. If such conditions persist longer or deteriorate further than expected, it is reasonably possible that the judgments and estimates could change, which may result in impairments of certain assets. Significant estimates include the useful lives of long- lived assets including property, equipment and intangible assets, impairment of assets, collectability of receivables, contingencies, stock-based compensation, and fair value of assets and liabilities acquired in business combinations.
Real Estate	Real Estate: Real estate assets are stated at cost, less accumulated depreciation and amortization. All costs related to the improvement or replacement of real estate properties are capitalized. Additions, renovations, and improvements that enhance and/or extend the useful life of a property are also capitalized. Expenditures for ordinary maintenance, repairs, and improvements that do not materially prolong the normal useful life of an asset, are charged to operations as incurred. The Company capitalizes all direct costs of real estate under development until the end of the development period. In addition, the Company capitalizes the indirect cost of insurance and real estate taxes allocable to real estate under development during the development period. The Company also capitalizes interest using the avoided cost method for real estate under development during the development period. The Company will cease the capitalization of these costs when development activities are substantially completed and the property is available for occupancy by tenants, but no later than one year from the completion of major construction activity at which time the property is placed in service and depreciation commences. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of these costs until activities are resumed. Real estate under development was $2.6 million and $5.6 million as of December 31, 2018 and 2017, respectively, and is included in buildings and improvements on the Company’s balance sheet. Upon the acquisition of real estate properties, the fair value of the real estate purchased is allocated to the acquired tangible assets (generally consisting of land, buildings and building improvements, and tenant improvements) and identified intangible assets and liabilities (generally consisting of above-market and below-market leases and the origination value of in-place leases) in accordance with GAAP. We utilize methods similar to those used by independent appraisers in estimating the fair value of acquired assets and liabilities. The fair value of the tangible assets of an acquired property considers the value of the property “as-if-vacant.” In allocating the purchase price to identified intangible assets and liabilities of an acquired property, the value of above-market and below-market leases is estimated based on the differences between contractual rentals and the estimated market rents over the applicable lease term discounted back to the date of acquisition utilizing a discount rate adjusted for the credit risk associated with the respective tenants. The aggregate value of in-place leases is measured based on the avoided costs associated with lack of revenue over a market oriented lease-up period, the avoided leasing commissions, and other avoided costs common in similar leasing transactions. Mortgage notes payable assumed in connection with acquisitions are recorded at their fair value using current market interest rates for similar debt at the time of acquisitions. Acquisition-related costs are expensed as incurred. The capitalized above-market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases and the capitalized below-market lease values are amortized as an increase to rental revenue over the remaining term of the respective leases. The value of in-place leases is based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors considered include estimates of carrying costs during expected lease-up periods, current market conditions, and costs to execute similar leases. The values of in-place leases are amortized over the remaining term of the respective leases. If a tenant vacates its space prior to its contractual expiration date, any unamortized balance of the related intangible assets or liabilities is recorded as income or expense in the period. The total net impact to rental revenues due to the amortization of above-market and below-market leases was a net increase in rental revenue of approximately $0.6 million and $0.4 million for the years ended December 31, 2018 and December 31, 2017, respectively. As of December 31, 2018, approximately $1.1 million and $10.9 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheets. As of December 31, 2017, approximately $1.4 million and $13.1 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheets. As of December 31, 2018 and 2017, approximately $5.0 million and $5.9 million (net of accumulated amortization), respectively, relating to below-market leases is included in acquired lease intangible liabilities, net in the accompanying consolidated balance sheets. The following table presents the projected increase to rental revenue from the amortization of the acquired above-market and below-market lease intangibles and the increase to amortization expense of the in-place lease intangibles for properties owned at December 31, 2018, over the next five years and thereafter (in thousands): Increase to Net amortization rental revenues expense 2019 $ 560 $ 1,955 2020 660 1,627 2021 510 1,400 2022 533 1,344 2023 635 1,189 Thereafter 974 3,345 $ 3,872 $ 10,860
Depreciation and Amortization	Depreciation and Amortization: The Company uses the straight-line method for depreciation and amortization. Properties and property improvements are depreciated over their estimated useful lives, which range from 5 to 40 years. Furniture, fixtures, and equipment are depreciated over estimated useful lives that range from 5 to 10 years. Tenant improvements are amortized over the shorter of the remaining non-cancellable term of the related leases or their useful lives.
Deferred Charges	Deferred Charges: Deferred charges consist principally of leasing commissions, which are amortized over the life of the related tenant leases, and financing costs, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets. If leases are terminated, the unamortized charges are expensed.
Asset Impairment	Asset Impairment: Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability is based on an estimate of the undiscounted future cash flows that are expected to result from the real estate investment’s use and eventual disposition. Such cash flow analyses consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Management is required to make subjective assessments as to whether there are impairments in the value of the Company’s real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period that the assessment is made. Management has determined that, based upon the demolition of its property located at 35 Executive Boulevard, Orange, Connecticut, and plans to construct a 41,000 square foot industrial building, an accelerated depreciation of $7.5 million should be recorded during 2018. Management has determined that there were no indicators of impairment relating to its remaining long-lived assets at December 31, 2018.
Reportable Segments	Reportable Segments: As of December 31, 2018, the Company primarily operated in one reportable segment, commercial real estate.
Revenue Recognition	Revenue Recognition: Rental income includes the base rent that each tenant is required to pay in accordance with the terms of their respective leases reported on a straight-line basis over the term of the lease. In order for management to determine, in its judgment, that the unbilled rent receivable applicable to each specific property is collectible, management reviews billed and unbilled rent receivables on a quarterly basis and takes into consideration the tenant’s payment history and financial condition. Some of the leases provide for additional contingent rental revenue in the form of percentage rents and increases based on the consumer price index, subject to certain maximums and minimums. Substantially all of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay for its pro rata share of real estate taxes, insurance, and ordinary maintenance and repairs for the property. Property operating expense recoveries from tenants of common area maintenance, real estate taxes, and other recoverable costs are recognized as revenues in the period that the related expenses are incurred.
Earnings Per Share Information	Earnings Per Share Information: The Company presents both basic and diluted earnings per share. Basic earnings per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, where such exercise or conversion would result in a lower per share amount. Restricted stock was included in the computation of basic and diluted earnings per share. Stock option awards were included in the computation of diluted earnings per share in 2018 and 2017 because the option awards were dilutive.
Cash and Cash Equivalents	Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash: Restricted cash includes a construction bond and reserves used to pay real estate taxes, insurance, repairs, leasing costs and capital improvements.
Fair Value Measurement	Fair Value Measurement: The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) 820-10-05 for financial assets and liabilities. This standard defines fair value, provides guidance for measuring fair value and requires certain disclosures. Fair value is defined as 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. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities disclosed at fair values are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are defined by ASC 820-10-35, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment, and the Company evaluates its hierarchy disclosures each quarter. The three-tier fair value hierarchy is as follows: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting management’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
Income Taxes	Income Taxes: The Company is organized and conducts its operations to qualify as a REIT for Federal income tax purposes. Accordingly, the Company is generally not subject to Federal income taxation on the portion of its distributable income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its REIT taxable income to its stockholders and complies with certain other requirements as defined in the Code. The Company also participates in certain activities conducted by entities which elected to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal, state, and local taxes on the income from these activities. The Company accounts for income taxes under the asset and liability method as required by the provisions of ASC 740-10-30. Under this method, deferred tax assets and liabilities are established based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance for deferred tax assets for which it does not consider realization of such assets to be more likely than not. ASC 740-10-65 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10-65, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. ASC 740-10-65 also provides guidance on de-recognition, classification, interest and penalties on income taxes, accounting in interim periods and requires increased disclosures. As of December 31, 2018 and 2017, the Company had determined that no liabilities are required in connection with unrecognized tax positions. As of December 31, 2018, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service. Any interest and penalties would be expensed as incurred. The recently enacted Tax Cuts and Jobs Act (the “Act”) is a complex revision to the U.S. federal income tax laws with impacts on different categories of taxpayers and industries, and will require subsequent rulemaking and interpretation in a number of areas. The Act may impact certain of our tenants’ operating results, financial condition, and future business plans. There can be no assurance that the Act will not impact our operating results, financial condition, and future business operations.
Concentrations of Credit Risk	Concentrations of Credit Risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, which from time-to-time exceed the federal depository insurance coverage. Beginning January 1, 2013, all noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit insurance amount of $250,000. Management believes that the Company is not exposed to any significant credit risk due to the credit worthiness of the financial institutions. Contractual rent of $9.7 million, derived from five leases with the City of New York, represented 22% of the Company’s total contractual rental income for the years ended December 31, 2018 and 2017, respectively.
Stock-Based Compensation	Stock-Based Compensation: The Company has a stock-based compensation plan, which is described below in Note 6. The Company accounts for stock-based compensation in accordance with ASC 718, which establishes accounting for stock-based awards. Under the provisions of ASC 718, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is expensed at the grant date (for the portion that vests immediately) or ratably over the respective vesting periods.
New Accounting Pronouncements	New Accounting Pronouncements: Lease Accounting In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, “Leases (Topic No. 842).” ASU 2016-02 requires lessees to recognize, at the commencement date, a lease liability for all leases with a term greater than 12 months, which is the lessee’s obligation to make lease payments arising from a lease and measure it on a discounted basis. A lessee must also recognize an asset representing the lessee’s right to use a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new lease accounting permits companies to utilize certain practical expedients in the implementation of the new standard. The Company intends to utilize a package of three practical expedients that must be elected together for all leases and includes, (i) not reassessing expired or existing contracts as to whether they are or contain leases; (ii) not reassessing lease classification of existing leases; and (iii) not reassessing the amount of capitalized initial direct costs for existing leases. ASU 2016-02 also specifies that upon adoption, lessors will no longer be able to capitalize and amortize certain leasing related costs and instead will only be permitted to capitalize and amortize incremental direct leasing costs. As a result, we have concluded that subsequent to adoption, there will be no change in the capitalization of costs as compared to what we have historically capitalized. ASU 2016-02 initially provided for one retrospective transition method for lessors; however, a second transition method was subsequently provided by ASU 2018-11 as described below. In July 2018, the FASB issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements,” which amended ASU 2016-02 to provide entities with an additional optional transition method to adopt ASU 2016-02. ASU 2018-11 simplifies transition requirements and, for lessors, provides a practical expedient for the separation of non-lease components from lease components. Specifically, ASU 2018-11 provides an option to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented in the financial statements. In addition, ASU 2018-11 provides a practical expedient, by class of underlying asset, that permits lessors to make a policy election not to separate non-lease components from the associated lease component, and, instead, to account for those components as a single component if the non-lease components would otherwise be accounted for under the new revenue guidance (Topic 606). If certain conditions are met, the single component will be accounted for under either Topic 842 or Topic 606 depending on which component(s) are predominant. In July 2018, the FASB issued ASU No. 2018-10, “Codification Improvements to Topic 842, Leases.” These amendments provide clarifications and corrections to ASU 2016-02, Leases (Topic 842). In December 2018, the FASB issued ASU No. 2018-20, “Leases, (Topic 842): Narrow-Scope Improvements for Lessors”. These amendments clarify or simplify certain narrow aspects of ASC 842 for lessors. This ASU modifies ASU No. 2016-02 to permit lessors, as an accounting policy election, not to evaluate whether certain sales taxes and other similar taxes are lessor costs or lessee costs. Instead, those lessors will account for those costs as if they are lessee costs. Consequently, a lessor making this election will exclude from the consideration in the contract and from variable payments not included in the consideration in the contract all collections from lessees of taxes within the scope of the election and will provide certain disclosures (the accounting policy election includes sales, use, value added, and some excise taxes but excludes real estate taxes). The Company has elected not to evaluate whether the aforementioned costs are lessor or lessee costs. This ASU also provides that certain lessor costs require lessors to exclude from variable payments, and therefore revenue, specifically lessor costs paid by lessees directly to third parties. The amendments also require lessors to account for costs excluded from the consideration of a contract that are paid by the lessor and reimbursed by the lessee as variable payments. A lessor will record those reimbursed costs as revenue. The adoption of ASU 2018-20 will not have a material impact on the Company’s consolidated financial statements. ASU 2016-02 is effective for fiscal periods and interim periods within those fiscal periods beginning after December 15, 2018. Early adoption is permitted. The Company will adopt ASU 2016-02 (as amended by subsequent ASUs) effective January 1, 2019 utilizing the new transition method described in ASU 2018-11 and the package of three practical expedients provided by ASU 2016-02 as described above. The Company anticipates that all of its leases will continue to be classified as operating leases and the adoption of ASU 2016-02 will not have a material impact on revenues. The Company intends to utilize the practical expedient related to the separation of lease and non-lease components provided by ASU 2018-11. The Company has determined that the effect of electing this lessor practical expedient is that revenues related to leases will be reported on one line in the presentation within the statement of income. The timing of revenue recognition is expected to be the same for the majority of the Company’s new leases as compared to similar existing leases. As lessee, the Company intends to utilize the practical expedients in the implementation of ASU 2016-02 related to not separating non-lease components from the associated lease component. As lessee, the Company is a party to an office lease with future lease obligations aggregating to $568 thousand as of December 31, 2018, for which the Company expects to record right-of-use assets and corresponding lease liabilities at the present value of the remaining minimum rental payments upon the adoption of ASU 2016-02. Other Accounting Topics In July 2018, the FASB issued ASU No. 2018-09, “Codification Improvements.” These amendments provide clarifications and corrections to certain ASC subtopics including the following: 220-10 (Income Statement – Reporting Comprehensive Income – Overall), 470-50 (Debt – Modifications and Extinguishments), 480-10 (Distinguishing Liabilities from Equity – Overall), 718-740 (Compensation – Stock Compensation – Income Taxes), 805-740 (Business Combinations – Income Taxes), 815-10 (Derivatives and Hedging – Overall), and 820-10 (Fair Value Measurement – Overall). Some of the amendments in ASU 2018-09 do not require transition guidance and are effective upon issuance; however, many of the amendments do not have transition guidance with effective dates for annual periods beginning after December 15, 2018. The Company is currently assessing the impact this guidance will have on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, “Compensation - Stock Compensation (Topic 718) – Improvements to Nonemployee Share-Based Payment Accounting.” These amendments provide specific guidance for transactions for acquiring goods and services from nonemployees and specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (i) financing to the issuer or (ii) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. This guidance is effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted but not earlier than the adoption of Topic 606. The Company does not believe that this guidance will have a material effect on its consolidated financial statements as it has not historically issued share-based payments in exchange for goods or services to be consumed within its operations. In March 2018, the FASB issued ASU No. 2018-05, “Income Taxes (Topic 740) – Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118”, which allowed public companies to record provisional amounts in earnings for the year ended December 31, 2017 due to the complexities involved in accounting for the enactment of the Tax Cuts and Jobs Act. ASU 2018-05 was effective upon issuance. The Company did not recognize any estimated income tax effects of the Tax Cuts and Jobs Act in its 2017 consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 118. In May 2017, the FASB issued ASU No. 2017-09, “Compensation – Stock Compensation (Topic 718) - Scope of Modification Accounting.” ASU 2017-09 clarifies Topic 718 such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (a) the fair value of the modified award is the same as the fair value of the original award immediately before the modification, (b) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification, and (c) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The amendments are effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. The adoption of ASU 2017-09 did not have a material impact on the Company’s consolidated financial statements. In February 2017, the FASB issued ASU No. 2017-05, “Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets.” ASU 2017-05 was issued to clarify the scope of Subtopic 610-20 and to add guidance for partial sales of nonfinancial assets, including partial sales of real estate. ASU 2017-05 clarifies the scope of Subtopic 610-20 by defining the term “in substance nonfinancial asset.” If substantially all of the fair value of the assets (recognized and unrecognized) promised to a counterparty in a contract is concentrated in nonfinancial assets, a financial asset in the same arrangement would still be considered part of an “in substance nonfinancial asset”. Additionally, ASU 2017-05 indicates an entity should identify each distinct nonfinancial asset (e.g., real estate and inventory) or in substance nonfinancial asset promised to a counterparty and derecognize each asset when a counterparty obtains control of it. ASU 2017-05 requires an entity to derecognize a distinct nonfinancial asset or distinct in substance nonfinancial asset in a partial sale transaction when two criteria are met: 1) the entity does not have (or ceases to have) a controlling financial interest in the legal entity that holds the asset in accordance with Topic 810, and 2) the entity transfers control of the asset in accordance with Topic 606. The effective date and transition requirements of ASU 2017-05 are the same as Topic 606. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within those periods. The adoption of ASU 2017-05 did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, “Business Combinations (Topic 805) - Clarifying the Definition of a Business.” ASU 2017-01 provides new guidance that changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets is not a business. ASU 2017-01 also requires a business to include at least one substantive process. ASU 2017-01 is effective for public business entities for fiscal years beginning after December 15, 2017 and has been adopted by the Company effective January 1, 2018. It is expected that the standard will reduce the number of future real estate acquisitions accounted for as a business combination and therefore, reduce the amount of acquisition costs that will be expensed. The adoption of ASU 2017-01 will result in a reduction of expensed acquisition costs and a corresponding increase to net income. There were no acquisitions during the year ended December 31, 2018. In November 2016, the FASB issued ASU No. 2016-18, “Statement of Cash Flows (Topic 230) - Restricted Cash.” ASU 2016-18 updates Topic 230 to require cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total cash amounts on the statement of cash flows. Consequently, transfers between cash and restricted cash will not be presented as a separate line item in the operating, investing or financing sections of the cash flow statement. The amendments are effective for public business entities for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years and should be applied retrospectively. Upon the adoption of ASU 2016-18, the Company reclassified approximately $1.2 million of its cash outflows from operating activities and $0.3 million of its cash inflows from investing activities to change in cash and restricted cash in its historical presentation of cash flows for the year ended December 31, 2017. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments.” ASU 2016-15 clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments are intended to reduce diversity in practice. The ASU contains additional guidance clarifying when an entity should separate cash receipts and cash payments and classify them into more than one class of cash flows (including when reasonable judgment is required to estimate and allocate cash flows) versus when an entity should classify the aggregate amount into one class of cash flows on the basis of predominance. The amendments are effective for public business entities for annual periods beginning after December 15, 2017 and interim periods within those annual periods. The adoption of ASU 2016-15 did not have a material impact on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration an entity expects to receive for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. ASU 2014-09 does not apply to the Company’s lease revenues but will apply to reimbursed tenant costs. Additionally, this guidance modifies disclosures regarding the nature, timing, amount and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14 which defers the effective date of ASU 2014-09 for all entities by one year, until fiscal years beginning after December 15, 2017, with early adoption permitted but not before fiscal years beginning after December 15, 2016. Entities may adopt ASU 2014-09 using either a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients or a modified retrospective approach with the cumulative effect recognized at the date of adoption. The Company believes the majority of its revenue falls outside the scope of this guidance and does not anticipate any significant changes to the timing of the Company’s revenue recognition. The Company implemented the standard using the modified retrospective approach. However, there was no cumulative effect recognized in retained earnings at the date of application.
