SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The summary of significant accounting policies presented below is designed to assist in understanding the Company’s consolidated financial statements. These accounting policies conform to accounting principles generally accepted in the United States of America (“GAAP”) in all material respects, and have been consistently applied in preparing the accompanying consolidated financial statements. Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Reclassifications Certain amounts in the Company’s prior period consolidated financial statements have been reclassified to conform to the current period presentation. The Company has chosen to break out real estate developments and capital expenditures of $738,000 from investment in real estate assets of $197.7 million , which was previously reported in total as $198.4 million in the Company’s consolidated statements of cash flows for the year ended December 31, 2016 . In addition, the Company has chosen to break out distribution and stockholder servicing fees paid of $79,000 from offering costs on issuance of common stock of $23.5 million , which was previously reported in total as $23.6 million in the Company’s consolidated statements of cash flows for the year ended December 31, 2016 . These reclassifications had no effect on previously reported totals or subtotals. Additionally, in connection with the adoption of Accounting Standards Update (“ASU”) 2016-15, as defined in “Recent Accounting Pronouncements,” the Company reclassified $1.1 million in contingent consideration payments made after a business combination from cash flows from operating activities to cash flows from investing activities for the year ended December 31, 2015. In connection with the adoption of ASU 2016-18, as defined in “Recent Accounting Pronouncements,” transfers to or from restricted cash which have previously been shown in the Company’s investing activities section of the consolidated statements of cash flows are now required to be shown as part of the total change in cash, cash equivalents and restricted cash in the consolidated statements of cash flows. This change resulted in a decrease in cash flows from investing activities of $1.9 million and $1.5 million during the years ended December 31, 2016 and 2015 , respectively. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Real Estate Assets Real estate assets are stated at cost, less accumulated depreciation and amortization. The Company considers the period of future benefit of each respective asset to determine the appropriate useful life. The estimated useful lives of the Company’s real estate assets by class are generally as follows: Buildings 40 years Site improvements 15 years Tenant improvements Lesser of useful life or lease term Intangible lease assets Lease term Recoverability of Real Estate Assets The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of its real estate assets may not be recoverable. Impairment indicators that the Company considers include, but are not limited to, bankruptcy or other credit concerns of a property’s major tenant, such as a history of late payments, rental concessions and other factors, a significant decrease in a property’s revenues due to lease terminations, vacancies, co-tenancy clauses, reduced lease rates, or other circumstances. When indicators of potential impairment are present, the Company assesses the recoverability of the assets by determining whether the carrying amount of the assets will be recovered through the undiscounted future cash flows expected from the use of the assets and their eventual disposition. In the event that such expected undiscounted future cash flows do not exceed the carrying amount, the Company will adjust the real estate assets to their respective fair values and recognize an impairment loss. Generally, fair value will be determined using a discounted cash flow analysis and recent comparable sales transactions. No impairment indicators were identified and no impairment losses were recorded during the years ended December 31, 2017 , 2016 or 2015 . Assets Held for Sale When a real estate asset is identified by the Company as held for sale, the Company will cease depreciation and amortization of the assets related to the property and estimate the fair value, net of selling costs. If, in management’s opinion, the fair value, net of selling costs, of the asset is less than the carrying amount of the asset, an adjustment to the carrying amount would be recorded to reflect the estimated fair value of the property, net of selling costs. There were no assets identified as held for sale as of December 31, 2017 or 2016 . Allocation of Purchase Price of Real Estate Assets Upon the acquisition of real properties, the Company allocates the purchase price to acquired tangible assets, consisting of land, buildings and improvements, and to identified intangible assets and liabilities, consisting of the value of above- and below-market leases and the value of in-place leases, based in each case on their respective fair values. The Company utilizes independent appraisals to assist in the determination of the fair values of the tangible assets of an acquired property (which includes land and buildings). The information in the appraisal, along with any additional information available to the Company’s management, is used in estimating the amount of the purchase price that is allocated to land. Other information in the appraisal, such as building value and market rents, may be used by the Company’s management in estimating the allocation of purchase price to the building and to intangible lease assets and liabilities. The appraisal firm has no involvement in management’s allocation decisions other than providing this market information. The fair values of above- and below-market lease intangibles are recorded based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between (1) the contractual amounts to be paid pursuant to the in-place leases and (2) an estimate of fair market lease rates for the corresponding in-place leases, which is generally obtained from independent appraisals, measured over a period equal to the remaining non-cancelable term of the lease including, for below-market leases, any bargain renewal periods. The above-market and below-market lease intangibles are capitalized as intangible lease assets or liabilities, respectively. Above-market leases are amortized as a reduction to rental income over the remaining terms of the respective leases. Below-market leases are amortized as an increase to rental income over the remaining terms of the respective leases, including any bargain renewal periods. In considering whether or not the Company expects a tenant to execute a bargain renewal option, the Company evaluates economic factors and certain qualitative factors at the time of acquisition, such as the financial strength of the tenant, remaining lease term, the tenant mix of the leased property, the Company’s relationship with the tenant and the availability of competing tenant space. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above-market or below-market lease intangibles relating to that lease would be recorded as an adjustment to rental income. The fair values of in-place leases include estimates of direct costs associated with obtaining a new tenant and opportunity costs associated with lost rental and other property income, which are avoided by acquiring a property with an in-place lease. Direct costs associated with obtaining a new tenant include leasing commissions, legal and other related expenses and are estimated in part by utilizing information obtained from independent appraisals and management’s consideration of current market costs to execute a similar lease. The intangible values of opportunity costs, which are calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease, are capitalized as intangible lease assets and are amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed. The Company may acquire certain properties subject to contingent consideration arrangements that may obligate the Company to pay additional consideration to the seller based on the outcome of future events. Additionally, the Company may acquire certain properties for which it funds certain contingent consideration amounts into an escrow account pending the outcome of certain future events. The outcome may result in the release of all or a portion of the escrow funds to the Company or the seller or a combination thereof. Prior to the adoption of ASU 2017-01 (as defined below) in April 2017, contingent consideration arrangements, including amounts funded through an escrow account, were recorded upon acquisition of the respective property at their estimated fair value, and any changes to the estimated fair value subsequent to acquisition were reflected in the accompanying consolidated statements of operations in acquisition-related fees and expenses. Upon adoption of ASU 2017-01 in April 2017, contingent consideration arrangements for asset acquisitions are recognized when the contingency is resolved. The determination of the amount of contingent consideration arrangements is based on the probability of several possible outcomes as identified by management. The Company estimates the fair value of assumed mortgage notes payable based upon indications of current market pricing for similar types of debt financing with similar maturities. Assumed mortgage notes payable are initially recorded at their estimated fair value as of the assumption date, and any difference between such estimated fair value and the mortgage note’s outstanding principal balance is amortized or accreted to interest expense over the term of the respective mortgage note payable. The determination of the fair values of the real estate assets and liabilities acquired requires the use of significant assumptions with regard to the current market rental rates, rental growth rates, capitalization and discount rates, interest rates and other variables. The use of alternative estimates may result in a different allocation of the Company’s purchase price, which could materially impact the Company’s results of operations. In April 2017, the Company elected to early adopt ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which clarifies the definition of a business by adding guidance to assist entities in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The Company expects its future acquisitions to qualify as asset acquisitions, and as such, the Company will allocate the purchase price to acquired tangible assets, consisting of land, buildings and improvements, and to identified intangible assets and liabilities, consisting of the value of above- and below-market leases and the value of in-place leases, based in each case on a relative fair value basis. Additionally, acquisition-related fees and certain acquisition-related expenses related to these asset acquisitions will be capitalized and allocated to tangible and intangible assets and liabilities as described above. Prior to the adoption of ASU 2017-01 in April 2017, all of the Company’s real estate acquisitions were accounted for as business combinations, and as such, acquisition-related expenses related to these business combination acquisitions were expensed as incurred. Prior to April 2017, acquisition-related expenses in the Company’s consolidated statements of operations primarily consisted of legal, deed transfer and other costs related to real estate purchase transactions, including costs incurred for deals that were not consummated. Development Activities Project costs and expenses, including interest incurred, associated with the development, construction and lease-up of a real estate project are capitalized as construction in progress. Once the development and construction of the building is substantially completed, the amounts capitalized to construction in progress are transferred to (i) land and (ii) buildings and improvements, and are depreciated over their respective useful lives. During the year ended December 31, 2017 , the Company capitalized $160,000 of interest expense associated with a completed expansion project. No interest expense associated with the expansion project was capitalized for the year ended December 31, 2016. Cash and Cash Equivalents and Restricted Cash Cash and cash equivalents include cash in bank accounts, as well as investments in highly-liquid money market funds. The Company deposits cash with several high quality financial institutions. These deposits are guaranteed by the Federal Deposit Insurance Company (“FDIC”) up to an insurance limit of $250,000. At times, the Company’s cash and cash equivalents may exceed federally insured levels. Although the Company bears risk on amounts in excess of those insured by the FDIC, it has not experienced and does not anticipate any losses due to the high quality of the institutions where the deposits are held. The Company had $1.4 million and $3.4 million in restricted cash as of December 31, 2017 and 2016 , respectively. Included in restricted cash was $1.2 million and $3.3 million held by lenders in lockbox accounts as of December 31, 2017 and 2016 , respectively. As part of certain debt agreements, rents from certain encumbered properties are deposited directly into a lockbox account, from which the monthly debt service payment is disbursed to the lender and the excess is disbursed to the Company. Restricted cash also included $165,000 and $120,000 held by a lender in an escrow account for a certain property in accordance with the associated loan agreement as of December 31, 2017 and 2016 , respectively. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the accompanying consolidated balance sheets to the combined amounts shown on the accompanying consolidated statements of cash flows (in thousands): As of December 31, 2017 2016 2015 Cash and cash equivalents $ 4,845 $ 6,993 $ 18,060 Restricted cash 1,431 3,443 1,540 Total cash and cash equivalents and restricted cash shown in the statement of cash flows $ 6,276 $ 10,436 $ 19,600 Distribution and Stockholder Servicing Fees The Company pays CCO Capital a distribution and stockholder servicing fee for Class T Shares that is calculated on a daily basis in the amount of 1/365th of 0.8% of the per share NAV of the Class T Shares that were sold in the primary portion of the Offering. The distribution and stockholder servicing fee is paid monthly in arrears. The aggregate distribution and stockholder servicing fee for Class T Shares will not exceed an amount equal to 4.0% of the total gross offering proceeds of Class T Shares sold in the primary portion of the Offering. The Company will cease paying the distribution and stockholder servicing fee with respect to Class T Shares sold in the Offering at the earliest of: (i) the end of the month in which the transfer agent, on the Company’s behalf, determines that total selling commissions and distribution and stockholder servicing fees paid by a stockholder within his or her individual account would be equal to 7.0% of the stockholder’s total gross investment amount at the time of the purchase of the primary Class T Shares held in such account; (ii) the date on which the aggregate underwriting compensation from all sources equals 10.0% of the gross offering proceeds (i.e., excluding proceeds from sales pursuant to the DRIP portion of the Offering); (iii) the fifth anniversary of the last day of the month in which such Class T Shares were purchased (excluding the offering of shares pursuant to DRIP portion of the Offering) terminates; (iv) the date such Class T Share is no longer outstanding; and (v) the date the Company effects a liquidity event (such as the sale of the Company, the sale of all or substantially all of the Company’s assets, a merger or similar transaction, the listing of the Company’s shares of common stock for trading on a national securities exchange or an alternative strategy that would result in a significant increase in the opportunities for stockholders to dispose of their shares). CCO Capital may, in its discretion, reallow to participating broker-dealers all or a portion of the distribution and stockholder servicing fee for services that such participating broker-dealers perform in connection with the distribution of Class T Shares. An estimated liability for future distribution and stockholder servicing fees payable to CCO Capital was recognized at the time each Class T Share was sold and included in due to affiliates in the consolidated balance sheets with a corresponding decrease to capital in excess of par value. Deferred Financing Costs Deferred financing costs represent commitment fees, legal fees and other costs associated with obtaining commitments for financing. These costs are amortized to interest expense over the terms of the respective financing agreements using the effective interest method. Unamortized deferred financing costs are written off when the associated debt is refinanced or repaid before maturity. The presentation of all deferred financing costs, other than those associated with the revolving loan portion of the credit facility, are classified such that the debt issuance costs related to a recognized debt liability are presented on the consolidated balance sheets as a direct deduction from the carrying amount of the related debt liability rather than as an asset. Debt issuance costs related to securing a revolving line of credit are presented as an asset and amortized ratably over the term of the line of credit arrangement. As such, the Company’s current and corresponding prior period total deferred costs, net in the accompanying consolidated balance sheets relate only to the revolving loan portion of the credit facility and the historical presentation, amortization and treatment of unamortized costs are still applicable. As of December 31, 2017 and 2016 , the Company had $760,000 and $1.5 million , respectively, of deferred financing costs, net of accumulated amortization, related to the revolving loan portion of the credit facility. Costs incurred in seeking financial transactions that do not close are expensed in the period in which it is determined the financing will not close. Due to Affiliates CCI II Advisors, and certain of its affiliates, received and will continue to receive fees, reimbursements, and compensation in connection with services provided relating to the Offerings and the acquisition, management, financing, and leasing of the properties of the Company. Derivative Instruments and Hedging Activities The Company accounts for its derivative instruments at fair value. Accounting for changes in the fair value of a derivative instrument depends on the intended use of the derivative instrument and the designation of the derivative instrument. The change in fair value of the effective portion of the derivative instrument that is designated as a hedge is recorded as other comprehensive income. The changes in fair value for derivative instruments that are not designated as hedges or that do not meet the hedge accounting criteria are recorded as a gain or loss to operations. Redeemable Common Stock Under the Company’s share redemption program, the Company’s obligation to redeem shares of its outstanding common stock is limited, among other things, to the net proceeds received by the Company from the sale of shares under the DRIP portion of the Offering and the DRIP Offering, net of shares redeemed to date. The Company records amounts that are redeemable under the share redemption program as redeemable common stock outside of permanent equity in its consolidated balance sheets. Changes in the amount of redeemable common stock from period to period are recorded as an adjustment to capital in excess of par value. Revenue Recognition Certain properties have leases where minimum rental payments increase during the term of the lease. The Company records rental income for the full term of each lease on a straight-line basis when earned and collectability is reasonably assured. When the Company acquires a property, the terms of existing leases are considered to commence as of the acquisition date for the purpose of this calculation. The Company defers the recognition of contingent rental income, such as percentage rents, until the specific target that triggers the contingent rental income is achieved. Expected reimbursements from tenants for recoverable real estate taxes and operating expenses are included in tenant reimbursement income in the period when such costs are incurred. The Company continually reviews receivables related to rent, including any straight-line rent, and current and future operating expense reimbursement from tenants and determines collectability by taking into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. In the event that the collectability of a receivable is uncertain, the Company will record an increase in the allowance for uncollectible accounts. As of December 31, 2017 and 2016 , the Company did not have an allowance for uncollectible accounts. Income Taxes The Company elected to be taxed and qualified as a REIT for federal income tax purposes under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended, commencing with its taxable year ended December 31, 2014. The Company will generally not be subject to federal corporate income tax to the extent it distributes its taxable income to its stockholders, and so long as it, among other things, distributes at least 90% of its annual taxable income (computed without regard to the dividends paid deduction and excluding net capital gains). REITs are subject to a number of other organizational and operational requirements. Even if the Company maintains its qualification for taxation as a REIT, it or its subsidiaries may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed income. Earnings (Loss) and Distributions Per Share The Company has two classes of common stock. Accordingly, the Company utilizes the two-class method to determine its earnings per share, which results in different earnings per share for each of the classes. Under the two-class method, earnings per share of each class of common stock are computed by dividing the sum of the distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted average number of shares for each class of common stock for the respective period. The distributed earnings to Class T Share common stockholders represents distributions declared less the distribution and stockholder servicing fees. Diluted income (loss) per share considers the effect of any potentially dilutive share equivalents, of which the Company had none for each of the years ended December 31, 2017 , 2016 or 2015 . Distributions per share is calculated based on the authorized daily distribution rate. Reportable Segment The Company’s commercial real estate assets consist primarily of single-tenant, income-producing necessity office and industrial properties, which are leased to creditworthy tenants under long-term net leases. The commercial properties are geographically diversified throughout the United States and have similar economic characteristics. The Company’s management evaluates operating performance on an overall portfolio level; therefore, the Company’s properties are one reportable segment. Recent Accounting Pronouncements From time to time, new accounting pronouncements are issued by various standard setting bodies that may have an impact on the Company’s accounting and reporting. Except as otherwise stated below, the Company is currently evaluating the effect that certain of these new accounting requirements may have on the Company’s accounting and related reporting and disclosures in the Company’s consolidated financial statements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which supersedes the revenue recognition requirements in Revenue Recognition, Accounting Standards Codification (“ASC”) (Topic 605) and will require an entity to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For public business entities, the guidance should be applied to annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Companies may use either a full retrospective or a modified retrospective approach to adopt ASU 2014-09. In accordance with the Company’s plan for the adoption of ASU 2014-09, the Company’s implementation team has identified all of the Company’s revenue streams and real estate sales and concluded that upon adoption, there will not be a material impact on the Company’s consolidated financial statements and disclosures. The Company plans to adopt ASU 2014-09 effective January 1, 2018 using the modified retrospective approach. In addition, the Company evaluated controls around the implementation of ASU 2014-09 and has concluded there will be no significant impact on the Company’s control structure. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than 12 months, with the result being the recognition of a right of use asset and a lease liability and the disclosure of key information about the entity’s leasing arrangements. The lessor accounting model under ASU 2016-02 is similar to current guidance; however it limits the capitalization of initial direct leasing costs, such as internally generated costs. ASU 2016-02 retains a distinction between finance leases (i.e., capital leases under current GAAP) and operating leases. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, with early adoption permitted. A modified retrospective approach is required for existing leases that have not expired upon adoption and provides for certain practical expedients. The Company is still evaluating the full impact of ASU 2016-02 on its consolidated financial statements; however, the Company plans to adopt ASU 2016-02 as of January 1, 2019 and anticipates that it will elect a practical expedient offered in ASU 2016-02 that allows an entity to not reassess the following upon adoption (elected as a group): (i) whether an expired or existing contract contains a lease arrangement; (ii) lease classification related to expired or existing lease arrangements; or (iii) whether costs incurred on expired or existing leases qualify as initial direct costs. As a result of the adoption, all leases for which we are the lessee, including ground leases (if any), will be recorded on the Company’s consolidated financial statements as either financing leases or operating leases with a related right of use asset and lease liability. In addition, certain executory and non-lease components, such as common area maintenance, may need to be accounted for separately from the lease component of the lease. Lease components will continue to be recognized on a straight-line basis over the lease term and certain non-lease components will be accounted for under the new revenue recognition guidance in ASU 2014-09 as mentioned above. In January 2018, the FASB proposed amending Topic 842 to allow lessors the option to combine lease and non-lease components when certain criteria are met. ASU No. 2016-01, Financial Instruments (Subtopic 825-10) (“ASU 2016-01”) — The amendments in this update require all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under the equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income (loss), the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update require separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the consolidated balance sheets or the accompanying notes to the consolidated financial statements. The amendments in this update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company will adopt ASU 2016-01 during the first quarter of fiscal year 2018 and does not expect it will have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) (“ASU 2016-13”). ASU 2016-13 is intended to improve financial reporting requiring more timely recognition of credit losses on loans and other financial instruments that are not accounted for at fair value through net income, including loans held for investment, held-to-maturity debt securities, trade and other receivables, net investment in leases and other such commitments. ASU 2016-13 requires that financial assets measured at amortized cost be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The amendments in ASU 2016-13 require the Company to measure all expected credit losses based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the financial assets and eliminates the “incurred loss” methodology under current GAAP. ASU 2016-13 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company is currently evaluating the impact this amendment will have on the Company’s consolidated financial statements. 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”), which is intended to address diversity in practice related to how certain cash receipts and cash payments are presented and classified in the statement of cash flows. ASU 2016-15 is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption permitted, and requires retrospective adoption unless it is impracticable to apply, in which case it is to be applied prospectively as of the earliest date practicable. The Company adopted ASU 2016-15 during the fourth quarter of fiscal year 2017 and has determined that this standard is releva |
