| Organization, Basis of Presentation and Summary of Significant Accounting Policies | Organization, Basis of Presentation and Summary of Significant Accounting Policies Business Retail Opportunity Investments Corp., a Maryland corporation (“ROIC”), is a fully integrated and self-managed real estate investment trust (“REIT”). ROIC specializes in the acquisition, ownership and management of necessity-based community and neighborhood shopping centers on the west coast of the United States anchored by supermarkets and drugstores. ROIC is organized in a traditional umbrella partnership real estate investment trust (“UpREIT”) format pursuant to which Retail Opportunity Investments GP, LLC, its wholly-owned subsidiary, serves as the general partner of, and ROIC conducts substantially all of its business through, its operating partnership subsidiary, Retail Opportunity Investments Partnership, LP, a Delaware limited partnership (the “Operating Partnership”), together with its subsidiaries. Unless otherwise indicated or unless the context requires otherwise, all references to the “Company”, “we,” “us,” “our,” or “our company” refer to ROIC together with its consolidated subsidiaries, including the Operating Partnership. With the approval of its stockholders, ROIC reincorporated as a Maryland corporation on June 2, 2011. ROIC began operations as a Delaware corporation, known as NRDC Acquisition Corp., which was incorporated on July 10, 2007, for the purpose of acquiring assets or operating businesses through a merger, capital stock exchange, stock purchase, asset acquisition or other similar business combination. On October 20, 2009, ROIC’s stockholders and warrantholders approved, among other things, the steps to be taken by ROIC to continue its business as a corporation that has elected to qualify as a REIT for U.S. federal income tax purposes. ROIC’s only material asset is its ownership of direct or indirect partnership interests in the Operating Partnership and membership interest in Retail Opportunity Investments GP, LLC, which is the sole general partner of the Operating Partnership. As a result, ROIC does not conduct business itself, other than acting as the parent company and issuing equity from time to time. The Operating Partnership holds substantially all the assets of the Company and directly or indirectly holds the ownership interests in the Company’s real estate ventures. The Operating Partnership conducts the operations of the Company’s business and is structured as a partnership with no publicly traded equity. Except for net proceeds from equity issuances by ROIC, which are contributed to the Operating Partnership, the Operating Partnership generates the capital required by the Company’s business through the Operating Partnership’s operations, by the Operating Partnership’s incurrence of indebtedness (directly and through subsidiaries) or through the issuance of operating partnership units (“OP Units”) of the Operating Partnership. Recent Accounting Pronouncements In November 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-18, Restricted Cash. ASU No. 2016-18 requires companies to include restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. Additionally, ASU No. 2016-18 requires a disclosure of a reconciliation between the statement of financial position and the statement of cash flows when the balance sheet includes more than one line item for cash, cash equivalents, restricted cash, and restricted cash equivalents. ASU No. 2016-18 is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, and will be applied retrospectively to all periods presented. The Company adopted ASU No. 2018-16 effective January 1, 2018. The adoption of ASU No. 2016-18 impacted the presentation of cash flows with inclusion of restricted cash flows for each of the presented periods. In February 2016, the FASB issued ASU No. 2016-2, “Leases.” ASU No. 2016-2 is expected to result in the recognition of a right-to-use asset and related liability to account for future obligations under ground lease agreements for which the Company is the lessee. As of June 30, 2018 , the remaining contractual payments under ground lease agreements aggregated approximately $41.1 million . In addition, ASU No. 2016-2 will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. As a lessor, under current accounting standards, the Company recognizes rental revenue from its operating leases on a straight-line basis over the respective lease terms. The Company commences recognition of rental revenue at the date the property is ready for its intended use and the tenant takes possession of or controls the physical use of the property. Under current accounting standards, tenant recoveries related to payments of real estate taxes, insurance, utilities, repairs and maintenance, common area expenses, and other operating expenses are considered lease components. The Company recognizes these tenant recoveries as revenue when services are rendered in an amount equal to the related operating expenses incurred that are recoverable under the terms of the applicable lease. Under ASU No. 2016-2, each lease agreement will be evaluated to identify the lease components and nonlease components at lease inception. The total consideration in the lease agreement will be allocated to the lease and nonlease components based on their relative standalone selling prices. Lessors will continue to recognize the lease revenue component using an approach that is substantially equivalent to existing guidance for operating leases (straight-line basis). In January 2018, the FASB issued a proposed amendment to ASU No. 2016-2 that would allow lessors to elect, as a practical expedient, not to allocate the total consideration to lease and nonlease components based on their relative standalone selling prices. If adopted, this practical expedient will allow lessors to elect a combined single lease component presentation if (i) the timing and pattern of the revenue recognition of the combined single lease component is the same, and (ii) the related lease component and, the combined single lease component would be classified as an operating lease. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company plans to adopt the provisions of ASU No. 2016-2 effective January 1, 2019 using the modified retrospective approach. The Company continues to evaluate the impact this pronouncement will have on the Company’s consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-9, “Revenue from Contracts with Customers.” The pronouncement was issued to clarify the principles for recognizing revenue and to develop a common revenue standard and disclosure requirements for U.S. GAAP and International Financial Reporting Standards. The pronouncement is effective for reporting periods beginning after December 15, 2017. As discussed above, leases are specifically excluded from ASU No. 2014-9 and will be governed by the applicable lease codification; however, this update may have implications on certain variable payment terms included in lease agreements. Upon adoption of ASU No. 2016-2 in 2019, the Company may be required to classify its tenant recoveries into lease and nonlease components, whereby the nonlease components would be subject to ASU No. 2014-9, pending the resolution of the proposed amendment issued by the FASB in January 2018. Property services categorized as nonlease components that are reimbursed by the Company’s tenants may need to be presented on a net basis if it is determined that the Company holds an agent arrangement. The Company adopted the provisions of ASU No. 2014-9 effective January 1, 2018 using the modified retrospective approach. The Company evaluated the revenue recognition for all contracts within this scope under existing accounting standards and under ASU No. 2014-9 and confirmed that there were no differences in the amounts recognized or the pattern of recognition. Therefore, the adoption of ASU 2014-9 did not result in an adjustment to the Company’s retained earnings on January 1, 2018. Principles of Consolidation The accompanying consolidated financial statements are prepared on the accrual basis in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statement disclosures. In the opinion of management, the consolidated financial statements include all adjustments necessary, which are of a normal and recurring nature, for the fair presentation of the Company’s financial position and the results of operations and cash flows for the periods presented. Results of operations for the three and six month periods ended June 30, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 . It is suggested that these financial statements be read in conjunction with the financial statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2017 . The consolidated financial statements include the accounts of the Company and those of its subsidiaries, which are wholly-owned or controlled by the Company. Entities which the Company does not control through its voting interest and entities which are variable interest entities (“VIEs”), but where it is not the primary beneficiary, are accounted for under the equity method. All significant intercompany balances and transactions have been eliminated. The Company follows the FASB guidance for determining whether an entity is a VIE and requires the performance of a qualitative rather than a quantitative analysis to determine the primary beneficiary of a VIE. Under this guidance, an entity would be required to consolidate a VIE if it has (i) the power to direct the activities that most significantly impact the entity’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could be significant to the VIE. The Company has concluded that the Operating Partnership is a VIE, and because they have both the power and the rights to control the Operating Partnership, they are the primary beneficiary and are required to continue to consolidate the Operating Partnership. A non-controlling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to a parent. Non-controlling interests are required to be presented as a separate component of equity in the consolidated balance sheet and modify the presentation of net income by requiring earnings and other comprehensive income to be attributed to controlling and non-controlling interests. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the disclosure of contingent assets and liabilities, the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the periods covered by the financial statements. The most significant assumptions and estimates relate to the purchase price allocations, depreciable lives, revenue recognition and the collectability of tenant receivables, other receivables, notes receivables, the valuation of performance-based restricted stock, stock options, and derivatives. Actual results could differ from these estimates. Federal Income Taxes The Company has elected to qualify as a REIT under Sections 856-860 of the Internal Revenue Code (the “Code”). Under those sections, a REIT that, among other things, distributes at least 90% of its REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gains) and meets certain other qualifications prescribed by the Code, will not be taxed on that portion of its taxable income that is distributed. Although it may qualify as a REIT for U.S. federal income tax purposes, the Company is subject to state income or franchise taxes in certain states in which some of its properties are located. In addition, taxable income from non-REIT activities managed through the Company’s taxable REIT subsidiary (“TRS”), if any, is fully subject to U.S. federal, state and local income taxes. For all periods from inception through September 26, 2013 the Operating Partnership had been an entity disregarded from its sole owner, ROIC, for U.S. federal income tax purposes and as such had not been subject to U.S. federal income taxes. Effective September 27, 2013, the Operating Partnership issued OP Units in connection with the acquisitions of two shopping centers. Accordingly, the Operating Partnership ceased being a disregarded entity and instead is being treated as a partnership for U.S. federal income tax purposes. The Company follows the FASB guidance that defines a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The FASB also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company records interest and penalties relating to unrecognized tax benefits, if any, as interest expense. As of June 30, 2018 , the statute of limitations for the tax years 2014 through and including 2016 remain open for examination by the Internal Revenue Service (“IRS”) and state taxing authorities. ROIC intends to make regular quarterly distributions to holders of its common stock. U.S. federal income tax law generally requires that a REIT distribute annually at least 90% of its REIT taxable income, without regard to the deduction for dividends paid and excluding net capital gains, and that it pay U.S. federal income tax at regular corporate rates to the extent that it annually distributes less than 100% of its net taxable income. ROIC intends to pay regular quarterly dividends to stockholders in an amount not less than its net taxable income, if and to the extent authorized by its board of directors. Before ROIC pays any dividend, whether for U.S. federal income tax purposes or otherwise, it must first meet both its operating requirements and its debt service on debt. If ROIC’s cash available for distribution is less than its net taxable income, it could be required to sell assets or borrow funds to make cash distributions or it may make a portion of the required distribution in the form of a taxable stock distribution or distribution of debt securities. Real Estate Investments 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 expenses transaction costs associated with business combinations and unsuccessful property asset acquisitions in the period incurred and capitalizes transaction costs associated with successful property asset acquisitions. During the six months ended June 30, 2018 and 2017 , capitalized costs related to the improvement or replacement of real estate properties were approximately $20.6 million and $21.6 million , respectively. The Company evaluates each acquisition of real estate to determine if the acquired property meets the definition of a business and needs to be accounted for as a business combination. Under ASU No. 2017-1, the Company first determines whether substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If this threshold is met, the acquired property does not meet the definition of a business and is accounted for as an asset acquisition. The Company expects that acquisitions of real estate properties will not meet the revised definition of a business because substantially all of the fair value is concentrated in a single identifiable asset or group of similar identifiable assets (i.e. land, buildings, and related intangible assets). The Company recognizes the acquisition of real estate properties, including acquired tangible assets (consisting of land, buildings and improvements), and acquired intangible assets and liabilities (consisting of above-market and below-market leases and acquired in-place leases) at their fair value (for acquisitions meeting the definition of a business) and relative fair value (for acquisitions not meeting the definition of a business). The relative fair values used to allocate the cost of an asset acquisition are determined using the same methodologies and assumptions the Company utilizes to determine fair value in a business combination. Acquired lease intangible assets include above-market leases and acquired in-place leases, and acquired lease intangible liabilities represent below-market leases, in the accompanying consolidated balance sheets. The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, which value is then allocated to land, buildings and improvements based on management’s determination of the relative fair values of these assets. In valuing an acquired property’s intangibles, factors considered by management include an estimate of carrying costs during the expected lease-up periods, and estimates of lost rental revenue during the expected lease-up periods based on management’s evaluation of current market demand. Management also estimates costs to execute similar leases, including leasing commissions, tenant improvements, legal and other related costs. Leasing commissions, legal and other related costs (“lease origination costs”) are classified as deferred charges in the accompanying consolidated balance sheets. The value of in-place leases is measured by the excess of (i) the purchase price paid for a property after adjusting existing in-place leases to market rental rates, over (ii) the estimated fair value of the property as if vacant. Above-market and below-market lease values are recorded based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between the contractual amounts to be received and management’s estimate of market lease rates, measured over the terms of the respective leases that management deemed appropriate at the time of acquisition. Such valuations include a consideration of the non-cancellable terms of the respective leases as well as any applicable renewal periods. The fair values associated with below-market rental renewal options are determined based on the Company’s experience and the relevant facts and circumstances that existed at the time of the acquisitions. The value of the above-market and below-market leases is amortized to base rental income, over the terms of the respective leases including option periods, if applicable. The value of in-place leases are amortized to expense over the remaining non-cancellable terms of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be recognized in operations at that time. The Company expenses transaction costs associated with business combinations and unsuccessful property asset acquisitions in the period incurred and capitalizes transaction costs associated with successful property asset acquisitions. In conjunction with the Company’s pursuit and acquisition of real estate investments, the Company did not expense any acquisition transaction costs during the three and six months ended June 30, 2018 . Asset Impairment The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset to aggregate future net cash flows (undiscounted and without interest) expected to be generated by the asset. If such assets are considered impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceed the fair value. Management does not believe that the value of any of the Company’s real estate investments was impaired at June 30, 2018 . Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed the federally insured limit by the Federal Deposit Insurance Corporation. The Company has not experienced any losses related to these balances. Restricted Cash The terms of the Company’s mortgage loans payable may require the Company to deposit certain replacement and other reserves with its lenders. Such “restricted cash” is generally available only for property-level requirements for which the reserves have been established and is not available to fund other property-level or Company-level obligations. Revenue Recognition Management has determined that all of the Company’s leases with its various tenants are operating leases. Rental income is generally recognized based on the terms of leases entered into with tenants. In those instances in which the Company funds tenant improvements and the improvements are deemed to be owned by the Company, revenue recognition will commence when the improvements are substantially completed and possession or control of the space is turned over to the tenant. When the Company determines that the tenant allowances are lease incentives, the Company commences revenue recognition and lease incentive amortization when possession or control of the space is turned over to the tenant for tenant work to begin. Minimum rental income from leases with scheduled rent increases is recognized on a straight-line basis over the lease term. Percentage rent is recognized when a specific tenant’s sales breakpoint is achieved. Property operating expense recoveries from tenants of common area maintenance, real estate taxes and other recoverable costs are recognized in the period the related expenses are incurred. Lease incentives are amortized as a reduction of rental revenue over the respective tenant lease terms. Termination fees (included in other income) are fees that the Company has agreed to accept in consideration for permitting certain tenants to terminate their lease prior to the contractual expiration date. The Company recognizes termination fees when the following conditions are met: (a) the termination agreement is executed; (b) the termination fee is determinable; (c) all landlord services pursuant to the terminated lease have been rendered; and (d) collectability of the termination fee is assured. Interest income is recognized as it is earned. Gains or losses on disposition of properties are recorded when the criteria for recognizing such gains or losses have been met. The Company must make estimates as to the collectability of its accounts receivable related to base rent, straight-line rent, expense reimbursements and other revenues. Management analyzes accounts receivable by considering tenant creditworthiness, current economic trends, and changes in tenants’ payment patterns when evaluating the adequacy of the allowance for doubtful accounts receivable. The Company also provides an allowance for future credit losses of the deferred straight-line rents receivable. The provision for doubtful accounts at June 30, 2018 and December 31, 2017 was approximately $6.7 million and $6.4 million , respectively. Depreciation and Amortization The Company uses the straight-line method for depreciation and amortization. Buildings are depreciated over the estimated useful lives which the Company estimates to be 39 - 40 years. Property improvements are depreciated over the estimated useful lives that range from 10 to 20 years. Furniture and fixtures are depreciated over the estimated useful lives that range from 3 to 10 years. Tenant improvements are amortized over the shorter of the life of the related leases or their useful life. Deferred Leasing and Internal Capitalized Leasing Costs Costs incurred in obtaining tenant leases (principally leasing commissions and acquired lease origination costs) are amortized ratably over the life of the tenant leases. The amortization of deferred leasing costs is included in Depreciation and amortization in the Consolidated Statements of Operations. The Company currently capitalizes a portion of payroll-related costs related to its leasing personnel associated with new leases and lease renewals. These costs are amortized over the life of the respective leases. During the three months ended June 30, 2018 and 2017 , the Company capitalized approximately $277,000 and $258,000 , respectively. During the six months ended June 30, 2018 and 2017 , the Company capitalized approximately $611,000 and $570,000 , respectively. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents and tenant receivables. The Company places its cash and cash equivalents in excess of insured amounts with high quality financial institutions. The Company performs ongoing credit evaluations of its tenants and requires tenants to provide security deposits. Earnings Per Share Basic earnings per share (“EPS”) excludes the impact of dilutive shares and is computed by dividing net income by the weighted average number of shares of common stock outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue shares of common stock were exercised or converted into shares of common stock and then shared in the earnings of the Company. For the three and six months ended June 30, 2018 and 2017 , basic EPS was determined by dividing net income allocable to common stockholders for the applicable period by the weighted average number of shares of common stock outstanding during such period. Net income during the applicable period is also allocated to the time-based unvested restricted stock as these grants are entitled to receive dividends and are therefore considered a participating security. Time-based unvested restricted stock is not allocated net losses and/or any excess of dividends declared over net income; such amounts are allocated entirely to the common stockholders other than the holders of time-based unvested restricted stock. The performance-based restricted stock awards outstanding under the Equity Incentive Plan described in Note 7 are excluded from the basic EPS calculation, as these units are not participating securities until they vest. The following table sets forth the reconciliation between basic and diluted EPS for ROIC (in thousands, except share data): Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Numerator: Net income $ 8,102 $ 9,197 $ 19,926 $ 20,448 Less income attributable to non-controlling interests (763 ) (888 ) (1,885 ) (1,969 ) Less earnings allocated to unvested shares (100 ) (80 ) (201 ) (160 ) Net income available for common stockholders, basic $ 7,239 $ 8,229 $ 17,840 $ 18,319 Numerator: Net income $ 8,102 $ 9,197 $ 19,926 $ 20,448 Less earnings allocated to unvested shares (100 ) (80 ) (201 ) (160 ) Net income available for common stockholders, diluted $ 8,002 $ 9,117 $ 19,725 $ 20,288 Denominator: Denominator for basic EPS – weighted average common equivalent shares 112,165,453 109,267,356 112,164,205 109,247,194 OP units 11,672,244 11,680,311 11,675,599 11,625,048 Restricted stock awards – performance-based 257,821 159,526 227,811 150,613 Stock options 109,471 130,741 110,323 133,314 Denominator for diluted EPS – weighted average common equivalent shares 124,204,989 121,237,934 124,177,938 121,156,169 Earnings Per Unit The following table sets forth the reconciliation between basic and diluted earnings per unit for the Operating Partnership (in thousands, except unit data): Three Months Ended June 30, Six Months Ended June 30, 2018 2017 2018 2017 Numerator: Net income $ 8,102 $ 9,197 $ 19,926 $ 20,448 Less earnings allocated to unvested shares (100 ) (80 ) (201 ) (160 ) Net income available to unitholders, basic and diluted $ 8,002 $ 9,117 $ 19,725 $ 20,288 Denominator: Denominator for basic earnings per unit – weighted average common equivalent units 123,837,697 120,947,667 123,839,804 120,872,242 Restricted stock awards – performance-based 257,821 159,526 227,811 150,613 Stock options 109,471 130,741 110,323 133,314 Denominator for diluted earnings per unit – weighted average common equivalent units 124,204,989 121,237,934 124,177,938 121,156,169 Stock-Based Compensation The Company has a stock-based employee compensation plan, which is more fully described in Note 7. The Company accounts for its stock-based compensation plans based on the FASB guidance which requires that compensation expense be recognized based on the fair value of the stock awards less estimated forfeitures. Restricted stock grants vest based upon the completion of a service period (“time-based grants”) and/or the Company meeting certain established market-specific financial performance criteria (“performance-based grants”). Time-based grants are valued according to the market price for the Company’s common stock at the date of grant. For performance-based grants, a Monte Carlo valuation model is used, taking into account the underlying contingency risks associated with the performance criteria. It is the Company’s policy to grant options with an exercise price equal to the quoted closing market price of stock on the grant date. Awards of stock options and time-based grants of stock are expensed as compensation on a straight-line basis over the vesting period. Depending on the terms of the agreement, certain awards of performance-based grants are expensed as compensation under the accelerated attribution method while certain are expensed as compensation on a straight-line basis over the vesting period. All awards of performance-based grants are recognized in income regardless of the results of the performance criteria. Derivatives The Company records all derivatives on the balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged forecasted transactions in a cash flow hedge. When the Company terminates a derivative for which cash flow hedging was being applied, the balance which was recorded in Other Comprehensive Income is amortized to interest expense over the remaining contractual term of the swap as long as the hedged forecasted transactions continue to be probable of occurring. The Company includes cash payments made to terminate |
