Accounting Policies [Abstract]
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. 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. Impact of COVID-19 On March 11, 2020, the novel coronavirus (“COVID-19”) was declared a pandemic (“COVID-19 pandemic”) by the World Health Organization as the disease spread throughout the world. The spread of COVID-19 is having a significant impact on the global economy, the U.S. economy, the economies of the local markets throughout the west coast in which the Company’s properties are located, and the broader financial markets. Nearly every industry has been impacted directly or indirectly, and the U.S. retail market has come under severe pressure due to numerous factors, including preventative measures taken by local, state and federal authorities to alleviate the public health crisis such as mandatory business closures, quarantines, restrictions on travel, restrictions on gatherings and social distancing practices. These containment measures, which in certain states and counties were relaxed or lifted for a period of time and subsequently reimposed, and then relaxed again, are affecting the operations of the Company’s tenant base to varying degrees depending on the category and location of the tenant. For example, grocery stores, pharmacies and retail stores are generally permitted to remain open and operational (with capacity limitations in the case of certain retail stores), restaurants in certain states such as California, Washington and Oregon have been generally limited to take-out and delivery services and outdoor-dining only or subject to capacity limitations when indoor dining has been permitted, and bars, movie theaters, gyms and salons in certain states and counties have been generally forced to close indoor operations for periods of time. There is uncertainty as to the time, date and extent to which these restrictions will be relaxed or lifted, whether restrictions that have been relaxed or lifted will be reimposed, or when or if customers will re-engage with tenants as they have in the past. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standard Update (“ASU”) No. 2016-2, “Leases.” ASU No. 2016-2 resulted 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. In addition, this ASU requires 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 are no longer capitalized as initial direct costs and instead are expensed as incurred. 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 July 2018, the FASB issued an amendment to ASU No. 2016-2 that allows 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. This practical expedient allows 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 amendment also provides a transition option that permits the application of the new guidance as of the adoption date rather than to all periods presented. 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 adopted the provisions of ASU No. 2016-2 effective January 1, 2019 using the modified retrospective approach and accordingly, recognized a lease liability of approximately $18.0 million, which is included in Other liabilities Based on its election of the package of practical expedients, the Company was not required to reassess whether any expired or existing contracts are or contain leases, reassess the lease classification for any expired or existing leases, or reassess initial direct costs for any existing leases. Accordingly, the Company’s ground lease agreements for which the Company is the lessee will continue to be accounted for as operating leases under the new standard. Further, the Company elected the practical expedient to account for both its lease and non-lease components as a combined single lease component and elected the optional transition method permitting January 1, 2019 to be its initial application date. Additionally, leasing payroll-related costs that are incurred regardless of whether leases are obtained are no longer capitalized as initial direct costs and instead are expensed as incurred. These costs amounted to approximately $1.3 million during the year ended December 31, 2018. Further, bad debt, which has previously been recorded in Property operating, has now been classified as a contra-revenue account in Rental revenue in the Company’s consolidated statements of operations and comprehensive income. In June 2016, the FASB issued ASU No. 2016-13 “Financial Instruments - Credit Topics.” ASU No. 2016-13 requires companies to adopt a new approach to estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans. The standard requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables. ASU No. 2016-13 was effective for reporting periods beginning on January 1, 2020. The Company adopted the provisions of ASU No. 2016-13 effective January 1, 2020, noting the pronouncement did not have a material impact on the Company’s consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04 “Reference Rate Reform (Topic 848).” ASU No. 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU No. 2020-04 is optional and may be elected over time as reference rate reform activities occur. During the quarter ended March 31, 2020, the Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur. Principles of Consolidation The accompanying consolidated financial statements are prepared on the accrual basis in accordance with GAAP. 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. 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 recoverability of assets to be held and used, purchase price allocations, depreciable lives, revenue recognition and the collectability of tenant receivables, other receivables, notes receivables, the valuation of performance-based restricted stock, LTIP Units (as defined below), 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. 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 December 31, 2020, the statute of limitations for the tax years 2016 through and including 2019 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. The Company intends to continue to operate its business in a manner that will allow it to qualify as a REIT, including maintaining compliance with taxable income distribution requirements. 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. During the years ended December 31, 2020 and 2019, capitalized costs related to the improvement or replacement of real estate properties were approximately $38.7 million and $38.0 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 is 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 years ended December 31, 2020, 2019 or 2018. Sales of real estate are recognized only when it is determined that the Company will collect substantially all of the consideration to which it is entitled, possession and other attributes of ownership have been transferred to the buyer and the Company has no controlling financial interest. The application of these criteria can be complex and requires the Company to make assumptions. Management has determined that all of these criteria were met for all real estate sold during the periods presented. 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. As discussed above, as a result of the COVID-19 pandemic, certain of the Company’s tenants may be unable to operate their businesses, maintain profitability and make timely rental payments to the Company under their leases. Accordingly, the worsening of estimated future cash flows could result in the recognition of an impairment charge on certain of the Company’s long-lived assets. Management does not believe that the value of any of the Company’s real estate investments was impaired at December 31, 2020 or December 31, 2019. 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. Prior to January 1, 2019, the Company considered property operating expense recoveries from tenants of common area maintenance, real estate taxes and other recoverable costs as lease components. Effective January 1, 2019, each lease agreement is evaluated to identify the lease and nonlease components at lease inception. The Company elected the single component practical expedient, which allows 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. As a result of this assessment, rental revenues and tenant recoveries from the lease of real estate assets are accounted for as a single component. Lease incentives are amortized as a reduction of rental revenue over the respective tenant lease terms. Termination fees (included in Other income in the consolidated statements of operations and comprehensive 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 substantially all of the termination fee is probable. 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, including the impact of the COVID-19 pandemic on tenants’ businesses, 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 allowance for doubtful accounts at December 31, 2020 and December 31, 2019 was approximately $18.6 million and $8.2 million, respectively. During the year ended December 31, 2020, the Company experienced a higher rate of projected uncollectible rental revenue driven by changes in expectations of collectability for certain tenants given the impact of the COVID-19 pandemic to such tenants. Additionally, certain tenants experiencing economic difficulties during this pandemic have sought and may continue to seek current and future rent relief, which may be provided in the form of rent deferrals, rent abatements or other possible agreements. Under ASC 842, “Leases,” subsequent changes to lease payments that are not stipulated in the original lease contract are generally accounted for as lease modifications. Due to the number of lease contracts that would require analysis to determine, on a lease by lease basis, whether such a concession is required to be accounted for as a lease modification, the FASB staff provided clarity as to an acceptable approach to accounting for lease concessions related to the effects of the COVID-19 pandemic. The FASB staff provided guidance that it would be acceptable for entities to make an election to account for lease concessions related to the effects of the COVID-19 pandemic consistent with how those concessions would be accounted for under ASC 842 as though enforceable rights and obligations for those concessions existed in the existing lease contract, as long as the concession does not result in a substantial increase in the rights of the lessor or the obligations of the lessee, thereby not requiring entities to apply lease modification guidance to those contracts. The Company has elected not to account for such COVID-19 concessions as lease modifications. Through December 31, 2020, the Company has entered into lease concessions that deferred approximately $6.2 million of contractual amounts billed. As of December 31, 2020, approximately $1.1 million of such deferred amounts has been rebilled, of which approximately $959,000, or 88% has been collected. The Company has evaluated and continues to evaluate rent relief requests on a case-by-case basis. Not all tenants requests have resulted or will ultimately result in concession agreements, nor is the Company foregoing its contractual rights under its lease agreements. Depreciation and Amortization The Company uses the straight-line method for depreciation and amortization. Buildings are depreciated over estimated useful lives which the Company estimates to be 39-40 years. Property improvements are depreciated over estimated useful lives that range from 10 to 20 years. Furniture and fixtures are depreciated over 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 Financing 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. Costs incurred in obtaining long-term financing are amortized ratably over the related debt agreement. The amortization of deferred leasing and financing costs is included in Depreciation and amortization and Interest expense and other finance expenses, respectively, in the consolidated statements of operations and comprehensive income. The unamortized balances of deferred leasing costs included in deferred charges in the Consolidated Balance Sheets as of December 31, 2020 that will be charged to future operations are as follows (in thousands): Lease Origination Costs 2021 $ 4,918 2022 4,146 2023 3,291 2024 2,516 2025 2,070 Thereafter 5,952 $ 22,893 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 years ended December 31, 2020, 2019 and 2018, 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 and LTIP Units outstanding under the Equity Incentive Plan described in Note 8 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): Year Ended December 31, 2020 2019 2018 Numerator: Net income $ 34,721 $ 53,683 $ 47,141 Less income attributable to non-controlling interests (2,707) (4,839) (4,405) Less earnings allocated to unvested shares (127) (453) (401) Net income available for common stockholders, basic $ 31,887 $ 48,391 $ 42,335 Numerator: Net income $ 34,721 $ 53,683 $ 47,141 Less earnings allocated to unvested shares (127) (453) (401) Net income available for common stockholders, diluted $ 34,594 $ 53,230 $ 46,740 Denominator: Denominator for basic EPS – weighted average common equivalent shares 116,731,930 114,177,528 112,645,490 OP units 9,785,334 11,334,408 11,626,312 Performance-based restricted stock awards and LTIP Units 106,434 206,100 183,683 Stock options 3,299 23,450 103,408 Denominator for diluted EPS – weighted average common equivalent shares 126,626,997 125,741,486 124,558,893 Earnings Per Unit The following table sets forth the reconciliation between basic and diluted earnings per unit for the Operating Partnership (in thou

Common Stock of ROIC	Common Stock of ROIC ATM On February 20, 2020, the ROIC entered into an “at the market” sales agreement (the “Sales Agreement”) with each of (i) KeyBanc Capital Markets Inc., BTIG, LLC, BMO Capital Markets Corp., BofA Securities, Inc., Capital One Securities, Inc., Citigroup Global Markets Inc., Jefferies LLC, J.P. Morgan Securities LLC, Raymond James & Associates, Inc., Regions Securities LLC, Robert W. Baird & Co. Incorporated and Wells Fargo Securities, LLC (collectively, the “Agents”) and (ii) the Forward Purchasers (as defined below), pursuant to which ROIC may sell, from time to time, shares (any such shares, the “Primary Shares”) of ROIC’s common stock, par value $0.0001 per share (“Common Stock”), to or through the Agents and instruct certain of the Agents, acting as forward sellers (the “Forward Sellers”), to offer and sell borrowed shares (any such shares, “Forward Hedge Shares,” and collectively with the Primary Shares, the “Shares”) with the Shares to be sold under the Sales Agreement having an aggregate offering price of up to $500.0 million. Additionally, ROIC simultaneously terminated the sales agreements with Capital One Securities, Inc., Jefferies LLC, KeyBanc Capital Markets Inc., Raymond James & Associates, Inc. and Robert W. Baird & Co. Incorporated, dated as of May 1, 2018 and as amended on April 29, 2019, which ROIC entered into in connection with its prior “at the market” offering. The Sales Agreement contemplates that, in addition to the issuance and sale of Primary Shares to or through the Agents as principal or its sales agents, ROIC may enter into separate forward sale agreements with any of KeyBanc Capital Markets Inc., BMO Capital Markets Corp., BofA Securities, Inc., Citigroup Global Markets Inc., Jefferies LLC, J.P. Morgan Securities LLC, Raymond James & Associates, Inc. and Wells Fargo Securities, LLC or their respective affiliates (in such capacity, the “Forward Purchasers”). If ROIC enters into a forward sale agreement with any Forward Purchaser, ROIC expects that such Forward Purchaser or its affiliate will borrow from third parties and, through the relevant Forward Seller, sell a number of Forward Hedge Shares equal to the number of shares of Common Stock underlying the particular forward sale agreement, in accordance with the mutually accepted instructions related to such forward sale agreement. ROIC will not initially receive any proceeds from any sale of Forward Hedge Shares through a Forward Seller. ROIC expects to fully physically settle each particular forward sale agreement with the relevant Forward Purchaser on one or more dates specified by ROIC on or prior to the maturity date of that particular forward sale agreement by issuing shares of Common Stock (the “Confirmation Shares”), in which case ROIC expects to receive aggregate net cash proceeds at settlement equal to the number of shares of Common Stock underlying the particular forward sale agreement multiplied by the relevant forward sale price. However, ROIC may also elect to cash settle or net share settle a particular forward sale agreement, in which case ROIC may not receive any proceeds from the issuance of shares of Common Stock, and ROIC will instead receive or pay cash (in the case of cash settlement) or receive or deliver shares of Common Stock (in the case of net share settlement). During the year ended December 31, 2020, ROIC did not sell any shares under the Sales Agreement. Stock Repurchase Program On July 31, 2013, ROIC’s board of directors authorized a stock repurchase program to repurchase up to a maximum of $50.0 million of the Company’s common stock. During the year ended December 31, 2020, the Company repurchased 673,868 shares of common stock under this program with a principal amount of approximately $8.8 million.

Share-based Payment Arrangement [Abstract]
Stock Compensation and Other Benefit Plans for ROIC	Stock Compensation and Other Benefit Plans for ROIC ROIC follows the FASB guidance related to stock compensation which establishes financial accounting and reporting standards for stock-based employee compensation plans, including all arrangements by which employees receive shares of stock or other equity instruments of the employer, or the employer incurs liabilities to employees in amounts based on the price of the employer’s stock. The guidance also defines a fair value-based method of accounting for an employee stock option or similar equity instrument. In 2018, the Company adopted the Company’s Amended and Restated 2009 Equity Incentive Plan (the “Equity Incentive Plan”). The types of awards that may be granted under the Equity Incentive Plan include stock options, restricted shares, share appreciation rights, phantom shares, dividend equivalent rights and other equity-based awards. The Equity Incentive Plan has a fungible unit system that counts the number of shares of the Company’s common stock used in the issuance of full-value awards, such as restricted shares and LTIP Units, differently than the number of shares of common stock used in the issuance of stock options. A total of 22,500,000 Fungible Units (as defined in the Equity Incentive Plan) are reserved for grant under the Equity Incentive Plan and the Fungible Unit-to-full-value award conversion ratio is 6.25 to 1.0. The Equity Incentive Plan will expire on April 25, 2028. The Company has made certain awards in the form of a separate series of units of limited partnership interests in its Operating Partnership called LTIP Units, which can be granted either as free-standing awards or in tandem with other awards under the Equity Incentive Plan. The LTIP Units are subject to such conditions and restrictions as the compensation committee may determine, including continued employment or service, achievement of pre-established operational performance goals and market-indexed performance criteria. Upon the occurrence of specified events and subject to the satisfaction of applicable vesting conditions, LTIP Units (after conversion into OP Units, in accordance with the Partnership Agreement) are ultimately redeemable for cash or for unregistered shares of ROIC common stock, at the option of ROIC, on a one-for-one basis. Restricted Stock During the year ended December 31, 2020, ROIC awarded 566,350 shares of restricted common stock under the Equity Incentive Plan, of which 192,238 shares are performance-based grants and the remainder of the shares are time-based grants.

Partners' Capital Notes [Abstract]
Capital of the Operating Partnership	Capital of the Operating Partnership As of December 31, 2020, the Operating Partnership had 127,051,238 OP Units outstanding. ROIC owned an approximate 92.9% interest in the Operating Partnership at December 31, 2020, or 118,085,155 OP Units. The remaining 8,966,083 OP Units are owned by other limited partners. A share of ROIC’s common stock and an OP unit have essentially the same economic characteristics as they share equally in the total net income or loss and distributions of the Operating Partnership. As of December 31, 2020, subject to certain exceptions, holders are able to redeem their OP Units, at the option of ROIC, for cash or for unregistered shares of ROIC common stock on a one-for-one basis. If cash is paid in the redemption, the redemption price is equal to the average closing price on the NASDAQ Stock Market for shares of ROIC’s common stock over the ten consecutive trading days immediately preceding the date a redemption notice is received by ROIC. During the year ended December 31, 2020, ROIC received notices of redemption for a total of 2,085,007 OP Units. ROIC elected to redeem 116,657 OP Units in cash, and accordingly, a total of approximately $2.0 million was paid during the year ended December 31, 2020 to the holder of the respective OP Units. In accordance with the Second Amended and Restated Agreement of Limited Partnership of the Operating Partnership, the redemption value of the OP Units was calculated based on the average closing price of ROIC’s common stock on the NASDAQ Stock Market for the ten consecutive trading days immediately preceding the date of receipt of the notice of redemption. ROIC elected to redeem the remaining 1,968,350 OP Units for shares of ROIC common stock on a one-for-one basis, and accordingly, 1,968,350 shares of ROIC common stock were issued. The redemption value of outstanding OP Units owned by the limited partners as of December 31, 2020, not including ROIC, had such units been redeemed at December 31, 2020, was approximately $119.7 million, calculated based on the average closing price of ROIC’s common stock on the NASDAQ Stock Market for the ten consecutive trading days immediately preceding December 31, 2020, which amounted to $13.35 per share. Retail Opportunity Investments GP, LLC, ROIC’s wholly-owned subsidiary, is the sole general partner of the Operating Partnership, and as the parent company, ROIC has the full and complete authority over the Operating Partnership’s day-to-day management and control. As the sole general partner of the Operating Partnership, ROIC effectively controls the ability to issue common stock of ROIC upon redemption of any OP Units. The redemption provisions that permit ROIC to settle the redemption of OP Units in either cash or common stock, in the sole discretion of ROIC, are further evaluated in accordance with applicable accounting guidance to determine whether temporary or permanent equity classification on the balance sheet is appropriate. The Company evaluated this guidance, including the ability, in its sole discretion, to settle in unregistered shares of common stock, and determined that the OP Units meet the requirements to qualify for presentation as permanent equity.

Fair Value of Financial Instrum

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company follows the FASB guidance that defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The guidance applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances. The guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the guidance establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. The following disclosures of estimated fair value were determined by management, using available market information and appropriate valuation methodologies as discussed in Note 1. Considerable judgment is necessary to interpret market data and develop estimated fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts realizable upon disposition of the financial instruments. The use of different market assumptions or estimation methodologies may have a material effect on the estimated fair value amounts. The carrying values of cash and cash equivalents, restricted cash, tenant and other receivables, deposits, prepaid expenses, other assets, accounts payable and accrued expenses are reasonable estimates of their fair values because of the short-term nature of these instruments. The carrying values of the term loan and revolving credit facility are deemed to be at fair value since the outstanding debt is directly tied to monthly LIBOR contracts. The fair value of the outstanding Senior Notes Due 2027 and Senior Notes Due 2026 at December 31, 2020 was approximately $245.6 million and $194.7 million, respectively, calculated using significant inputs which are not observable in the market, or Level 3. The fair value of the outstanding Senior Notes Due 2024 and Senior Notes Due 2023 at December 31, 2020 was approximately $264.0 million and $269.1 million, respectively, based on inputs not quoted on active markets, but corroborated by market data, or Level 2. Assumed mortgage notes payable were recorded at their fair value at the time they were assumed. The Company’s outstanding mortgage notes payable were estimated to have a fair value of approximately $86.2 million with a weighted average interest rate of 3.8% as of December 31, 2020. These fair value measurements fall within Level 3 of the fair value hierarchy.

Derivative and Hedging Activiti

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The following is a summary of the terms of the Company’s current interest rate swaps as of December 31, 2020 (in thousands): Swap Counterparty Notional Amount Effective Date Maturity Date Interest Rate Swap Agreements: Bank of Montreal $ 100,000 12/29/2017 8/31/2022 U.S. Bank $ 100,000 12/29/2017 8/31/2022 Regions Bank $ 50,000 1/31/2019 8/31/2022 Royal Bank of Canada $ 50,000 1/31/2019 8/31/2022 The changes in the fair value of derivatives that are designated as cash flow hedges are recorded in accumulated other comprehensive income (“AOCI”) and will be subsequently reclassified into earnings during the period in which the hedged forecasted transaction affects earnings. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves, and implied volatilities. The fair value of interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. The Company incorporated credit valuation adjustments to appropriately reflect both its own non-performance risk and the respective counterparties’ non-performance risk in the fair value measurements. In adjusting the fair value of its derivative contract for the effect of non-performance risk, the Company considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. However, as of December 31, 2020, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative position and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuation in its entirety is classified in Level 2 of the fair value hierarchy. The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis, aggregated by the level in the fair value hierarchy within which those measurements fall (in thousands): Quoted Prices in Active Markets for Identical Assets and Liabilities (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total December 31, 2020: Liabilities Derivative financial instruments $ — $ (9,511) $ — $ (9,511) December 31, 2019: Liabilities Derivative financial instruments $ — $ (3,865) $ — $ (3,865) Amounts paid, or received, to cash settle interest rate derivatives prior to their maturity date are recorded in AOCI at the cash settlement amount, and will be reclassified to interest expense as interest expense is recognized on the hedged debt. During the next twelve months, the Company estimates that $5.8 million will be reclassified as a non-cash increase to interest expense related to the Company’s four outstanding swap arrangements and its previously cash-settled swap arrangements. The table below presents the fair value of the Company’s derivative financial instruments as well as their classification on the balance sheet as of December 31, 2020 and December 31, 2019, respectively (in thousands): Derivatives designed as hedging instruments Balance sheet location December 31, 2020 Fair Value December 31, 2019 Fair Value Interest rate products Other liabilities $ (9,511) $ (3,865) Derivatives in Cash Flow Hedging Relationships The table below details the location in the financial statements of the gain or loss recognized on interest rate derivatives designated as cash flow hedges for the years ended December 31, 2020, 2019, and 2018, respectively (in thousands): Year Ended December 31, 2020 2019 2018 Amount of (loss) gain recognized in OCI on derivatives $ (9,925) $ (7,348) $ 1,648 Amount of loss (gain) reclassified from AOCI into interest $ 4,572 $ (345) $ 57

Accounting Policies [Abstract]
New Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standard Update (“ASU”) No. 2016-2, “Leases.” ASU No. 2016-2 resulted 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. In addition, this ASU requires 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 are no longer capitalized as initial direct costs and instead are expensed as incurred. 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 July 2018, the FASB issued an amendment to ASU No. 2016-2 that allows 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. This practical expedient allows 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 amendment also provides a transition option that permits the application of the new guidance as of the adoption date rather than to all periods presented. 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 adopted the provisions of ASU No. 2016-2 effective January 1, 2019 using the modified retrospective approach and accordingly, recognized a lease liability of approximately $18.0 million, which is included in Other liabilities Based on its election of the package of practical expedients, the Company was not required to reassess whether any expired or existing contracts are or contain leases, reassess the lease classification for any expired or existing leases, or reassess initial direct costs for any existing leases. Accordingly, the Company’s ground lease agreements for which the Company is the lessee will continue to be accounted for as operating leases under the new standard. Further, the Company elected the practical expedient to account for both its lease and non-lease components as a combined single lease component and elected the optional transition method permitting January 1, 2019 to be its initial application date. Additionally, leasing payroll-related costs that are incurred regardless of whether leases are obtained are no longer capitalized as initial direct costs and instead are expensed as incurred. These costs amounted to approximately $1.3 million during the year ended December 31, 2018. Further, bad debt, which has previously been recorded in Property operating, has now been classified as a contra-revenue account in Rental revenue in the Company’s consolidated statements of operations and comprehensive income. In June 2016, the FASB issued ASU No. 2016-13 “Financial Instruments - Credit Topics.” ASU No. 2016-13 requires companies to adopt a new approach to estimating credit losses on certain types of financial instruments, such as trade and other receivables and loans. The standard requires entities to estimate a lifetime expected credit loss for most financial instruments, including trade receivables. ASU No. 2016-13 was effective for reporting periods beginning on January 1, 2020. The Company adopted the provisions of ASU No. 2016-13 effective January 1, 2020, noting the pronouncement did not have a material impact on the Company’s consolidated financial statements.
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements are prepared on the accrual basis in accordance with GAAP. 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. 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	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 recoverability of assets to be held and used, purchase price allocations, depreciable lives, revenue recognition and the collectability of tenant receivables, other receivables, notes receivables, the valuation of performance-based restricted stock, LTIP Units (as defined below), and derivatives. Actual results could differ from these estimates.
Federal Income Taxes	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. 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 December 31, 2020, the statute of limitations for the tax years 2016 through and including 2019 remain open for examination by the Internal Revenue Service (“IRS”) and state taxing authorities.
Real Estate Investments	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. During the years ended December 31, 2020 and 2019, capitalized costs related to the improvement or replacement of real estate properties were approximately $38.7 million and $38.0 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.
Asset Impairment	Asset Impairment
Cash and Cash Equivalents	Cash and Cash Equivalents
Restricted Cash	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	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. Prior to January 1, 2019, the Company considered property operating expense recoveries from tenants of common area maintenance, real estate taxes and other recoverable costs as lease components. Effective January 1, 2019, each lease agreement is evaluated to identify the lease and nonlease components at lease inception. The Company elected the single component practical expedient, which allows 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. As a result of this assessment, rental revenues and tenant recoveries from the lease of real estate assets are accounted for as a single component. Lease incentives are amortized as a reduction of rental revenue over the respective tenant lease terms. Termination fees (included in Other income in the consolidated statements of operations and comprehensive 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 substantially all of the termination fee is probable. 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.
Depreciation and Amortization	Depreciation and Amortization The Company uses the straight-line method for depreciation and amortization. Buildings are depreciated over estimated useful lives which the Company estimates to be 39-40 years. Property improvements are depreciated over estimated useful lives that range from 10 to 20 years. Furniture and fixtures are depreciated over 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 Charges	Deferred Leasing and Financing 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. Costs incurred in obtaining long-term financing are amortized ratably over the related debt agreement. The amortization of deferred leasing and financing costs is included in Depreciation and amortization and Interest expense and other finance expenses, respectively, in the consolidated statements of operations and comprehensive income.
Concentration Credit Risk	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	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 years ended December 31, 2020, 2019 and 2018, 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
Share-based Compensation	Stock-Based Compensation The Company has a stock-based employee compensation plan, which is more fully described in Note 8. The Company accounts for its stock-based compensation plan based on the FASB guidance which requires that compensation expense be recognized based on the fair value of the stock awards less forfeitures. Restricted stock grants vest based upon the completion of a service period (“time-based restricted stock grants”) and/or the Company meeting certain pre-established operational performance goals and market-indexed financial performance criteria (“performance-based restricted stock 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 restricted stock grants subject to market-indexed performance criteria, a Monte Carlo valuation model is used, taking into account the underlying contingency risks associated with the performance criteria. All other performance-based restricted stock grants are valued according to the market price of the Company’s common stock at the date of grant. 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. The Company has made certain separate awards in the form of units of limited partnership interests in its Operating Partnership called LTIP Units (“LTIP Units”). The LTIP Units are subject to such conditions and restrictions as the compensation committee may determine, including continued employment or service, achievement of pre-established operational performance goals and market-indexed performance criteria. For the LTIP Units subject to market-indexed performance criteria (the “marked-indexed LTIP Units”), a Monte Carlo valuation model is used, taking into account the underlying contingency risks associated with the performance criteria. All other LTIP Units (the “operational LTIP Units”) are valued according to the market price of the Company’s common stock at the date of grant.
Derivatives	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 derivative as long as the hedged forecasted transactions continue to be probable of occurring. The Company includes cash payments made to terminate interest rate derivatives as an operating activity on the statement of cash flows, given the nature of the underlying cash flows that the derivative was hedging.
Segment Reporting	Segment Reporting The Company’s primary business is the ownership, management, and redevelopment of retail real estate properties. The Company reviews operating and financial information for each property on an individual basis and therefore, each property represents an individual operating segment. The Company evaluates financial performance using property operating income, defined as operating revenues (base rent and recoveries from tenants), less property and related expenses (property operating expenses and property taxes). The Company has aggregated the properties into one reportable segment as the properties share similar long-term economic characteristics and have other similarities including the fact that they are operated using consistent business strategies, are typically located in major metropolitan areas, and have similar tenant mixes.
Reclassifications	ReclassificationsCertain reclassifications have been made to the prior period consolidated financial statements and notes to conform to the current year presentation. In connection with the adoption of ASU No. 2016-2 and the Company’s practical expedient election to have a combined single lease component presentation, the Company combined Base rents and Recoveries from tenants into a single line item, Rental revenues, in its consolidated statements of operations and comprehensive income.
