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. 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 with one or more assets or control of one or more operating businesses. On October 20, 2009, ROIC’s stockholders and warrantholders approved each of the proposals presented at the special meetings of stockholders and warrantholders, respectively, in connection with the transactions contemplated by the Framework Agreement (the “Framework Agreement”) ROIC entered into on August 7, 2009 with NRDC Capital Management, LLC, which, among other things, sets forth 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 warrants exercised and 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 January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-1, “Business Combinations: Clarifying the Definition of a Business.” The pronouncement changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The pronouncement requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. 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 2017-1 effective October 1, 2016. For the period from October 1, 2016 through December 31, 2016, the Company acquired three properties for which it was concluded substantially all of the fair value of the assets acquired with each property acquisition was concentrated in a single identifiable asset and did not meet the definition of a business under ASU 2017-1. Acquisition transaction costs associated with these property acquisitions were capitalized to real estate investments. In February 2016, the FASB issued ASU No. 2016-2, “Leases.” The pronouncement requires lessees to put most leases on their balance sheets but recognize expenses on their income statements. The guidance also eliminates real estate-specific provisions for all entities. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. 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 ASU 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 December 31, 2016 , the remaining contractual payments under ground lease agreements aggregated approximately $43.0 million . In addition, the new ASU 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. The Company continues to evaluate the impact this pronouncement will have on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments.” The pronouncement simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. The pronouncement requires any adjustments to provisional amounts to be applied prospectively. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-16 effective January 1, 2016 and the adoption did not have a material impact on the consolidated financial statements of the Company. In April 2015, the FASB issued ASU No. 2015-3, “Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” The pronouncement requires reporting entities to present debt issuance costs related to a note as a direct deduction from the face amount of that note presented in the balance sheet. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-3 effective January 1, 2016 and retrospectively applied the guidance to its debt obligations for all periods presented, which resulted in the presentation of debt issuance costs associated with its term loan, unsecured revolving credit facility, Senior Notes Due 2024, Senior Notes Due 2023, and mortgage notes payable as a direct reduction from the carrying amount of the related debt instrument. These amounts were previously included in deferred charges, net on the Company’s consolidated balance sheets. See Note 5. In February 2015, the FASB issued ASU No. 2015-2, “Amendments to the Consolidation Analysis.” The pronouncement focuses to minimize situations under previously existing guidance in which a reporting entity was required to consolidate another legal entity in which that reporting entity did not have: (1) the ability through contractual rights to act primarily on its own behalf; (2) ownership of the majority of the legal entity’s voting rights; or (3) the exposure to a majority of the legal entity’s economic benefits. ASU 2015-2 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. ASU 2015-2 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-2 effective January 1, 2016, and there were no changes to the Company’s consolidation conclusions as a result of the adoption of this guidance. 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. The Company plans to adopt the provisions of ASU No. 2014-9 effective January 1, 2018 using the modified retrospective approach. Leases are specifically excluded from this ASU and will be governed by the applicable lease codification; however, this update may have implications on certain variable payment terms included in lease agreements. The Company continues to evaluate the impact this pronouncement will have on the Company’s consolidated financial statements. 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. Effective January 1, 2016, the Company adopted the provisions of ASU No 2015-2, and as a result, concluded that the Operating Partnership is a VIE. The Company has concluded that 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 modifies 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, 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 has been an entity disregarded from its sole owner, ROIC, for U.S. federal income tax purposes and as such has not been subject to 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 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, 2016 , the statute of limitations for tax years 2013 through and including 2015 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 years ended December 31, 2016 and 2015 , capitalized costs related to the improvements or replacement of real estate properties were approximately $41.4 million and $28.1 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 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 (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 (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 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. In conjunction with the Company’s pursuit and acquisition of real estate investments, the Company expensed acquisition transaction costs during the years ended December 31, 2016 , 2015 and 2014 of approximately $824,000 , $1.0 million and $1.0 million , respectively. 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 December 31, 2016 . 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 several of the Company’s mortgage loans payable 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 in accordance with Securities and Exchange Commission Staff Accounting Bulletin 104, “Revenue Recognition,” 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 under GAAP 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 December 31, 2016 and December 31, 2015 was approximately $5.2 million and $4.5 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 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. The unamortized balances of deferred leasing costs included in deferred charges in the Consolidated Balance Sheet as of December 31, 2016 that will be charged to future operations are as follows (in thousands): Lease Origination Costs 2017 $ 7,645 2018 6,139 2019 4,773 2020 3,953 2021 3,113 Thereafter 9,130 $ 34,753 The unamortized balances of deferred financing costs associated with the Company’s term loan, unsecured revolving credit facility, Senior Notes Due 2026, Senior Notes Due 2024, Senior Notes Due 2023, and mortgage notes payable included as a direct reduction from the carrying amount of the related debt instrument in the Consolidated Balance Sheet as of December 31, 2016 that will be charged to future operations are as follows (in thousands): Financing Costs 2017 $ 2,116 2018 2,081 2019 683 2020 556 2021 555 Thereafter 1,438 $ 7,429 Internal Capitalized Leasing Costs The Company 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 years ended December 31, 2016 , 2015 and 2014 , the Company capitalized approximately $1.2 million , $1.1 million and $947,000 , respectively, of such payroll-related costs. 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. During the year ended December 31, 2014 , the effect of approximately 41,400,000 warrants to purchase the Company’s common stock (the “Public Warrants”) issued in connection with the Company’s initial public offering (the “IPO”), and the 8,000,000 warrants (the “Private Placement Warrants”) purchased by NRDC Capital Management, LLC simultaneously with the consummation of the IPO, for the time these were outstanding during these periods, were included in the calculation of diluted EPS since the weighted average share price was greater than the exercise price during these periods. No warrants were outstanding during the years ended December 31, 2016 and 2015 . For the years ended December 31, 2016 , 2015 and 2014 , 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 grants awarded under the 2009 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, 2016 2015 2014 Numerator: Net income $ 36,430 $ 25,092 $ 21,050 Less income attributable to non-controlling interests (3,676 ) (1,228 ) (749 ) Less earnings allocated to unvested shares (270 ) (229 ) (160 ) Net income available for common stockholders, basic $ 32,484 $ 23,635 $ 20,141 Numerator: Net income $ 36,430 $ 25,092 $ 21,050 Less earnings allocated to unvested shares (270 ) (229 ) (160 ) Net income available for common stockholders, diluted $ 36,160 $ 24,863 $ 20,890 Denominator: Denominator for basic EPS – weighted average common equivalent shares 104,072,222 95,651,780 83,411,230 Warrants — — 631,086 OP units 11,747,509 4,086,724 3,162,658 Restricted stock awards – performance-based 86,996 174,198 162,327 Stock options 133,213 105,079 86,108 Denominator for diluted EPS – weighted average common equivalent shares 116,039,940 100,017,781 87,453,409 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): Year Ended December 31, 2016 2015 2014 Numerator: Net income $ 36,430 $ 25,092 $ 21,050 Less earnings allocated to unvested shares (270 ) (229 ) (160 ) Net income available to unitholders, basic and diluted $ 36,160 $ 24,863 $ 20,890 Denominator: Denominator for basic earnings per unit – weighted average common equivalent units 115,819,731 99,738,504 86,573,888 Warrants — — 631,086 Restricted stock awards – performance-based 86,996 174,198 162,327 Stock options 133,213 105,079 86,108 Denominator for diluted earnings per unit – weighted average common equivalent units 116,039,940 100,017,781 87,453,409 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 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 stoc

Additionally, the Operating Partnership is obligated to pay a facility fee at a rate based on the credit rating level of the Company, currently 0.20% , and a fronting fee at a rate of 0.125% per year with respect to each letter of credit issued under the credit facility. The Company has investment grade credit ratings from Moody’s Investors Service (Baa2) and Standard & Poor’s Ratings Services (BBB-). Both the term loan and credit facility contain customary representations, financial and other covenants. The Operating Partnership’s ability to borrow under the term loan and credit facility are subject to its compliance with financial covenants and other restrictions on an ongoing basis.

Common Stock and Warrants of ROIC	Common Stock and Warrants of ROIC Equity Issuance On July 12, 2016, ROIC issued 6,555,000 shares of common stock in a registered public offering, including shares issued upon the exercise in full of the underwriters’ option to purchase additional shares, resulting in net proceeds of approximately $133.0 million , after deducting the underwriters’ discounts and commissions and offering expenses. The net proceeds were used to reduce borrowings under the Operating Partnership’s $500.0 million unsecured revolving credit facility. On August 10, 2015, ROIC issued 5,520,000 shares of common stock in a registered public offering, including shares issued upon the exercise in full of the underwriters’ option to purchase additional shares, resulting in net proceeds of approximately $87.4 million , after deducting the underwriters’ discounts and commissions and offering expenses. The net proceeds were used to reduce borrowings under the Operating Partnership’s $500.0 million unsecured revolving credit facility. ATM On September 19, 2014, ROIC entered into four separate Sales Agreements (the “Original Sales Agreements”) with each of Jefferies LLC, KeyBanc Capital Markets Inc., MLV & Co. LLC and Raymond James & Associates, Inc. (each individually, an “Original Agent” and collectively, the “Original Agents”) pursuant to which ROIC may sell, from time to time, shares of ROIC’s common stock, par value $0.0001 per share, having an aggregate offering price of up to $100.0 million through the Original Agents either as agents or principals. On May 23, 2016, ROIC entered into two additional sales agreements (the “Additional Sales Agreements”, and together with the Original Sales Agreements, the “Sales Agreements”) with each of Canaccord Genuity Inc. and Robert W. Baird & Co. Incorporated (the “Additional Agents”, and together with the Original Agents, the “Agents”) pursuant to which the Company may sell shares of ROIC’s common stock through the Additional Agents either as agents or principals. In addition, on May 19, 2016, the Company terminated the Original Sales Agreement with MLV & Co. LLC. During the year ended December 31, 2016 , ROIC sold a total of 2,202,254 shares of common stock under the Sales Agreements, which resulted in gross proceeds of approximately $45.6 million and commissions of approximately $584,000 paid to the Agents. During the year ended December 31, 2015 , ROIC sold a total of 544,567 shares under the Sales Agreements, which resulted in gross proceeds of approximately $9.9 million and commissions of approximately $149,000 paid to the Agents. Warrants Simultaneously with the consummation of the IPO, NRDC Capital Management, LLC purchased 8,000,000 Private Placement Warrants at a purchase price of $1.00 per warrant. The Private Placement Warrants were identical to the Public Warrants except that the Private Placement Warrants were exercisable on a cashless basis as long as they were still held by NRDC Capital Management, LLC or its members, members of its members’ immediate family or their controlled affiliates. The purchase price of the Private Placement Warrants approximated the fair value of such warrants at the purchase date. On February 4, 2013, NRDC exercised the outstanding 8,000,000 Private Placement Warrants on a cashless basis pursuant to which ROIC issued 688,500 shares to NRDC. ROIC had the right to redeem all of the outstanding warrants it issued in the IPO, at a price of $0.01 per warrant upon 30 days’ notice while the warrants were exercisable, only in the event that the last sale price of the common stock is at least a specified price. The terms of the warrants were as follows: • The exercise price of the warrants was $12.00 . • The price at which ROIC’s common stock must trade before ROIC was able to redeem the warrants it issued in the IPO was $18.75 . • To provide that a warrantholder’s ability to exercise warrants was limited to ensure that such holder’s “Beneficial Ownership” or “Constructive Ownership,” each as defined in ROIC’s charter, did not exceed the restrictions contained in the charter limiting the ownership of shares of ROIC’s common stock. ROIC had reserved 53,400,000 shares for the exercise of the Public Warrants and the Private Placement Warrants, and issuance of shares under ROIC’s 2009 Equity Incentive Plan (the “2009 Plan”).

Stock Compensation and Other Benefit Plans for ROIC	Stock Compensation and Other Benefit Plans for ROIC The Company 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. During 2009, the Company adopted the 2009 Plan. The 2009 Plan provides for grants of restricted common stock and stock option awards up to an aggregate of 7.5% of the issued and outstanding shares of the Company’s common stock at the time of the award, subject to a ceiling of 4,000,000 shares. Restricted Stock During the year ended December 31, 2016 , ROIC awarded 350,614 shares of restricted common stock under the 2009 Plan, of which 121,150 shares are performance-based grants and the remainder of the shares are time based grants. The performance-based grants vest based on pre-defined market-specific performance criteria with a vesting date on January 1, 2019. A summary of the status of the Company’s non-vested restricted stock awards as of December 31, 2016 , and changes during the year ended December 31, 2016 are presented below: Shares Weighted Average Non-vested at December 31, 2015 627,471 $ 14.39 Granted 350,614 $ 17.33 Vested (310,295 ) $ 13.99 Forfeited (7,332 ) $ 17.62 Non-vested at December 31, 2016 660,458 $ 16.10 As of December 31, 2016 , there remained a total of $5.0 million of unrecognized restricted stock compensation related to outstanding non-vested restricted stock grants awarded under the 2009 Plan. Restricted stock compensation is expected to be expensed over a remaining weighted average period of 1.7 years (irrespective of achievement of the performance conditions). The total fair value of restricted stock that vested during the years ended December 31, 2016 , 2015 and 2014 was $5.6 million , $4.6 million and $2.9 million , respectively. Stock Based Compensation Expense For the years ended December 31, 2016 , 2015 and 2014 , the amounts charged to expense for all stock based compensation totaled approximately $4.9 million , $4.7 million and $3.7 million , respectively. Profit Sharing and Savings Plan During 2011, the Company established a profit sharing and savings plan (the “401K Plan”), which permits eligible employees to defer a portion of their compensation in accordance with the Code. Under the 401K Plan, the Company made matching contributions on behalf of eligible employees. The Company made contributions to the 401K Plan of approximately $76,000 , $31,000 and $25,000 for the years ended December 31, 2016 , 2015 and 2014 , respectively.

Partners' Capital Notes [Abstract]
Capital of the Operating Partnership	Capital of the Operating Partnership As of December 31, 2016 , the Operating Partnership had 120,969,823 OP Units outstanding. ROIC owned an approximate 90.3% interest in the Operating Partnership at December 31, 2016 , or 109,301,762 OP Units. The remaining 11,668,061 OP Units are owned by other limited partners. A share of ROIC’s common stock and the OP Units 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, 2016 , 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, 2015, in connection with the acquisition of Bellevue Marketplace, the property formerly known as Sternco Shopping Center, the Operating Partnership issued 1,946,483 OP Units whereby the Operating Partnership was required to deliver cash in exchange for the OP Units upon redemption if such OP Units were redeemed on or before January 31, 2016 (“Redeemable OP Units”). These Redeemable OP Units were previously classified as mezzanine equity as of December 31, 2015 because, as of such date, ROIC could be required to deliver cash upon the redemption of such OP Units. During the year ended December 31, 2016 , the Company received notices of redemption for 1,828,825 Redeemable OP Units. The Company redeemed the OP Units in cash at a price of $17.30 , in accordance with the Third Amendment to the Second Amended and Restated Agreement of Limited Partnership, as amended, of the Operating Partnership, and accordingly, a total of approximately $31.6 million was paid to the holders of the respective Redeemable OP Units. The remaining 117,658 Redeemable OP Units are treated as permanent equity as ROIC now has the option, in its sole discretion, to settle the redemption of the OP Units in cash or unregistered shares of ROIC common stock. During the year ended December 31, 2016 , ROIC received notices of redemption for a total of 1,133,550 OP Units (excluding Redeemable OP Units, described above). ROIC elected to redeem 755,762 OP Units for shares of ROIC common stock on a one-for-one basis, and accordingly, 755,762 shares of ROIC common stock were issued. ROIC elected to redeem the remaining 377,788 OP Units in cash. The redemption value of the OP Units owned by the limited partners as of December 31, 2016 , not including ROIC, had such units been redeemed at December 31, 2016 , was approximately $242.2 million , calculated based on the average closing price on the NASDAQ Stock Market of ROIC common stock for the ten consecutive trading days immediately preceding December 31, 2016 , which amounted to $20.76 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 2026 at December 31, 2016 is approximately $191.2 million , calculated using significant inputs which are not observable in the market. The fair value, based on inputs not quoted on active markets, but corroborated by market data, or Level 2, of the outstanding Senior Notes Due 2024 at December 31, 2016 is approximately $238.8 million . The fair value, based on inputs not quoted on active markets, but corroborated by market data, or Level 2, of the outstanding Senior Notes Due 2023 at December 31, 2016 is approximately $255.3 million . Assumed mortgage notes payable were recorded at their fair value at the time they were assumed and are estimated to have a fair value of approximately $35.9 million with an interest rate range of 3.6% to 4.7% and a weighted average interest rate of 3.9% as of December 31, 2016 . Mortgage notes payable originated by the Company are estimated to have a fair value of approximately $32.6 million with an interest rate of 4.7% as of December 31, 2016 . These fair value measurements fall within level 3 of the fair value hierarchy.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative and Hedging Activities	Derivative and Hedging Activities The Company’s objectives in using interest rate derivatives historically were to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company used 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 interest rate swaps as of December 31, 2016 (in thousands): Swap Counterparty Notional Amount Effective Date Maturity Date Bank of Montreal $ 50,000 1/29/2016 1/31/2019 Regions Bank $ 50,000 2/29/2016 1/31/2019 The effective portion of 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 counterparty’s 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, 2016 , 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).

In management’s opinion, the liabilities, if any, that ultimately may result from such legal actions are not expected to have a material adverse effect on the consolidated financial position, results of operations or liquidity of the Company. The Company has signed several ground leases for certain properties. For financial reporting purposes, rent expense is recognized on a straight-line basis over the term of the lease. Accordingly, rent expense recognized in excess of rent paid is reflected as a liability in the accompanying consolidated balance sheets. Rent expense, for both ground leases and corporate office storage space, was approximately $831,000 , $1.2 million , and $1.2 million for the years ended December 31, 2016 , 2015 , and 2014 , respectively.

Accounting Policies [Abstract]
New Accounting Pronouncements	Recent Accounting Pronouncements In January 2017, the FASB issued Accounting Standards Update (“ASU”) No. 2017-1, “Business Combinations: Clarifying the Definition of a Business.” The pronouncement changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The pronouncement requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. 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 2017-1 effective October 1, 2016. For the period from October 1, 2016 through December 31, 2016, the Company acquired three properties for which it was concluded substantially all of the fair value of the assets acquired with each property acquisition was concentrated in a single identifiable asset and did not meet the definition of a business under ASU 2017-1. Acquisition transaction costs associated with these property acquisitions were capitalized to real estate investments. In February 2016, the FASB issued ASU No. 2016-2, “Leases.” The pronouncement requires lessees to put most leases on their balance sheets but recognize expenses on their income statements. The guidance also eliminates real estate-specific provisions for all entities. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. 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 ASU 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 December 31, 2016 , the remaining contractual payments under ground lease agreements aggregated approximately $43.0 million . In addition, the new ASU 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. The Company continues to evaluate the impact this pronouncement will have on the Company’s consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments.” The pronouncement simplifies the accounting for adjustments made to provisional amounts recognized in a business combination by eliminating the requirement to retrospectively account for those adjustments. The pronouncement requires any adjustments to provisional amounts to be applied prospectively. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-16 effective January 1, 2016 and the adoption did not have a material impact on the consolidated financial statements of the Company. In April 2015, the FASB issued ASU No. 2015-3, “Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs.” The pronouncement requires reporting entities to present debt issuance costs related to a note as a direct deduction from the face amount of that note presented in the balance sheet. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-3 effective January 1, 2016 and retrospectively applied the guidance to its debt obligations for all periods presented, which resulted in the presentation of debt issuance costs associated with its term loan, unsecured revolving credit facility, Senior Notes Due 2024, Senior Notes Due 2023, and mortgage notes payable as a direct reduction from the carrying amount of the related debt instrument. These amounts were previously included in deferred charges, net on the Company’s consolidated balance sheets. See Note 5. In February 2015, the FASB issued ASU No. 2015-2, “Amendments to the Consolidation Analysis.” The pronouncement focuses to minimize situations under previously existing guidance in which a reporting entity was required to consolidate another legal entity in which that reporting entity did not have: (1) the ability through contractual rights to act primarily on its own behalf; (2) ownership of the majority of the legal entity’s voting rights; or (3) the exposure to a majority of the legal entity’s economic benefits. ASU 2015-2 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. ASU 2015-2 is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company adopted the provisions of ASU No. 2015-2 effective January 1, 2016, and there were no changes to the Company’s consolidation conclusions as a result of the adoption of this guidance. 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. The Company plans to adopt the provisions of ASU No. 2014-9 effective January 1, 2018 using the modified retrospective approach. Leases are specifically excluded from this ASU and will be governed by the applicable lease codification; however, this update may have implications on certain variable payment terms included in lease agreements. The Company continues to evaluate the impact this pronouncement will have 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. Effective January 1, 2016, the Company adopted the provisions of ASU No 2015-2, and as a result, concluded that the Operating Partnership is a VIE. The Company has concluded that 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 modifies 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 purchase price allocations, depreciable lives, revenue recognition and the collectability of tenant receivables, other receivables, notes receivables, the valuation of performance-based restricted stock, 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. 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 has been an entity disregarded from its sole owner, ROIC, for U.S. federal income tax purposes and as such has not been subject to 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 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, 2016 , the statute of limitations for tax years 2013 through and including 2015 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	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 years ended December 31, 2016 and 2015 , capitalized costs related to the improvements or replacement of real estate properties were approximately $41.4 million and $28.1 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 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 (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 (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 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.
Asset Impairment	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.
Cash and Cash Equivalents	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.
Restricted Cash	Restricted Cash The terms of several of the Company’s mortgage loans payable 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. 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 in accordance with Securities and Exchange Commission Staff Accounting Bulletin 104, “Revenue Recognition,” 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 under GAAP 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.
Depreciation and Amortization	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 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.
Internal Capitalized Leasing Costs	Internal Capitalized Leasing Costs The Company 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.
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. During the year ended December 31, 2014 , the effect of approximately 41,400,000 warrants to purchase the Company’s common stock (the “Public Warrants”) issued in connection with the Company’s initial public offering (the “IPO”), and the 8,000,000 warrants (the “Private Placement Warrants”) purchased by NRDC Capital Management, LLC simultaneously with the consummation of the IPO, for the time these were outstanding during these periods, were included in the calculation of diluted EPS since the weighted average share price was greater than the exercise price during these periods. No warrants were outstanding during the years ended December 31, 2016 and 2015 . For the years ended December 31, 2016 , 2015 and 2014 , 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 grants awarded under the 2009 Plan described in Note 8 are excluded from the basic EPS calculation, as these units are not participating securities until they vest.
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 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 an 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.
Non-Controlling Interests – Redeemable OP Units / Redeemable Limited Partners	Non-Controlling Interests – Redeemable OP Units / Redeemable Limited Partners OP Units are classified as either mezzanine equity or permanent equity. If ROIC could be required to deliver cash in exchange for the OP Units upon redemption, such OP Units are referred to as Redeemable OP Units and presented in the mezzanine section of the balance sheet. If ROIC could, in its sole discretion, deliver cash or shares of ROIC common stock in exchange for the OP Units upon redemption, such OP Units are classified as permanent equity and presented in the equity section of the balance sheet. As of December 31, 2016 , all outstanding OP Units are classified as permanent equity. See Note 9 for further discussion.
Derivatives	Derivatives The Company records all derivatives on the balance sheet 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 risk in a fair value hedge or the earnings effect of 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. The Company includes cash payments made to terminate interest rate swaps 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 financing 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.
Reclassification	Reclassifications Certain reclassifications have been made to the prior period consolidated financial statements and notes to conform to the current year presentation.
