Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Nature of Business SITE Centers Corp. and its related consolidated real estate subsidiaries (collectively, the “Company” or “SITE Centers”) and unconsolidated joint ventures are primarily engaged in the business of acquiring, owning, developing, redeveloping, expanding, leasing, financing and managing shopping centers. Unless otherwise provided, references herein to the Company or SITE Centers include SITE Centers Corp. and its wholly-owned subsidiaries and consolidated joint ventures. The Company’s tenant base primarily includes national and regional retail chains and local tenants. Consequently, the Company’s credit risk is concentrated in the retail industry. Amounts relating to the number of properties, square footage, tenant and occupancy data, joint ventures interests and estimated project costs are unaudited. Retail Value Inc. On July 1, 2018, the Company completed the spin-off of Retail Value Inc. (“RVI”). At the time of the spin-off, RVI owned 48 shopping centers, comprised of 36 continental U.S. assets and all 12 of SITE Centers’ shopping centers in Puerto Rico, representing $2.7 billion of gross book asset value and $1.27 billion of mortgage debt (Note 4). In connection with the spin-off, on July 1, 2018, the Company and RVI entered into a separation and distribution agreement, pursuant to which, among other things, the Company agreed to transfer the properties and certain related assets, liabilities and obligations to RVI and to distribute 100% of the outstanding common shares of RVI to holders of record of SITE Centers SITE Centers SITE On July 1, 2018, the Company and RVI also entered into an external management agreement, which, together with various property management agreements, governs the fees, terms and conditions pursuant to which SITE Centers Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the results of the Company and all entities in which the Company has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). All significant inter-company balances and transactions have been eliminated in consolidation. Investments in real estate joint ventures in which the Company has the ability to exercise significant influence, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or loss) of these joint ventures is included in consolidated net income (loss). The Company has two unconsolidated joint ventures included in the Company’s joint venture investments that are considered VIEs for which the Company is not the primary beneficiary. The Company’s maximum exposure to losses associated with these VIEs is limited to its aggregate investment, which was $114.0 million and $192.2 million as of December 31, 2019 and 2018, respectively. Reclassifications Certain amounts in prior periods have been reclassified in order to conform with the current period’s presentation. The Company reclassified $13.4 million and $23.9 million of contractual lease payments from Fee and Other Income to Rental Income within total revenues on its consolidated statements of operations for the years ended December 31, 2018 and 2017, respectively, in connection with the adoption of Accounting Standards Update (“ASU”) No. 2016-02— Leases, Topic 842”), Statements of Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information Non-cash investing and financing activities are summarized as follows (in millions): For the Year Ended December 31, 2019 2018 2017 Accounts payable related to construction in progress $ 11.0 $ 9.3 $ 13.4 Mortgage assumed, shopping center acquisition 9.1 — — Contribution of net assets to RVI — 663.4 — Write-off of preferred share original issuance costs (Note 12) 7.2 — — Dividends declared, but not paid 44.0 45.3 78.5 Assumption of buildings due to ground lease terminations — 2.2 8.6 Land acquired by minority interest partner — 2.3 — Conversion of Operating Partnership Units — 0.9 — Receivable and reduction of real estate assets, net – hurricane — — 65.9 Real Estate Real estate assets, which include construction in progress and undeveloped land, are stated at cost less accumulated depreciation. Depreciation and amortization is recorded on a straight-line basis over the estimated useful lives of the assets as follows: Buildings Useful lives, ranging from 31.5 to 40 years Building improvements and fixtures Useful lives, ranging from 5 to 20 years Tenant improvements Shorter of economic life or lease terms The Company periodically assesses the useful lives of its depreciable real estate assets and accounts for any revisions, which are not material for the periods presented, prospectively. Expenditures for maintenance and repairs are charged to operations as incurred. Significant expenditures that improve or extend the life of the asset are capitalized. Construction in Progress and Land includes undeveloped land as well as construction in progress related to shopping center developments and expansions. The Company capitalized certain direct costs (salaries and related personnel) and incremental internal construction costs of $3.8 million, $5.7 million and $7.4 million in 2019, 2018 and 2017, respectively. Purchase Price Accounting The Company’s acquisitions were accounted for as asset acquisitions, and the Company capitalized the acquisition costs incurred. Upon acquisition of properties, the Company estimates the fair value of acquired tangible assets, consisting of land, building and improvements and intangibles, generally including above- and below-market leases and in-place leases. The Company allocates the purchase price to assets acquired and liabilities assumed on a gross basis based on their relative fair values at the date of acquisition. In estimating the fair value of the tangible and intangible assets acquired, the Company considers information obtained about each property as a result of its due diligence and marketing and leasing activities and uses various valuation methods, such as estimated cash flow projections using appropriate discount and capitalization rates, analysis of recent comparable sales transactions, estimates of replacement costs net of depreciation and other available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. Above- and below-market lease values are recorded based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management's estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the estimated term of any below-market, fixed-rate renewal options for below-market leases. The capitalized above- and below-market lease values are amortized to base rental revenue over the related lease term plus fixed-rate renewal options, as appropriate. The value of acquired in-place leases is recorded based on the estimated average number of months of lease-up multiplied by the estimated gross monthly market rental rate for each individual lease. Such amounts are amortized to expense over the remaining initial lease term. Real Estate Impairment Assessment The Company reviews its individual real estate assets, including undeveloped land and construction in progress, and intangibles for potential impairment indicators whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment indicators include, but are not limited to, significant decreases in projected net operating income and occupancy percentages, estimated hold periods, projected losses on potential future sales, market factors, significant changes in projected development costs or completion dates and sustainability of development projects. An asset is considered impaired when the undiscounted future cash flows are not sufficient to recover the asset’s carrying value. The determination of anticipated undiscounted cash flows is inherently subjective, requiring significant estimates made by management, and considers the most likely expected course of action at the balance sheet date based on current plans, intended holding periods and available market information. If the Company is evaluating the potential sale of an asset, the undiscounted future cash flows analysis is probability-weighted based upon management’s best estimate of the likelihood of the alternative courses of action as of the balance sheet date. If an impairment is indicated, an impairment loss is recognized based on the excess of the carrying amount of the asset over its fair value. The Company recorded aggregate impairment charges of $3.4 million, $69.3 million and $340.5 million, related to consolidated real estate investments, during the years ended December 31, 2019, 2018 and 2017, respectively (Note 14). Disposition of Real Estate and Real Estate Investments Sales of nonfinancial assets, such as real estate, are recognized when control of the asset transfers to the buyer, which will occur when the buyer has the ability to direct the use of, or obtain substantially all of the remaining benefits from, the asset. This generally occurs when the transaction closes and consideration is exchanged for control of the asset. A discontinued operation includes only the disposal of a component of an entity and represents a strategic shift that has (or will have) a major effect on an entity’s financial results. The disposition of the Company’s individual properties did not qualify for discontinued operations presentation, and thus, the results of the properties that have been sold remain in income from continuing operations, and any associated gains or losses from the disposition are included in Gain on Disposition of Real Estate. Real Estate Held for Sale The Company generally considers assets to be held for sale when management believes that a sale is probable within a year. This generally occurs when a sales contract is executed with no substantive contingencies and the prospective buyer has significant funds at risk. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value, less cost to sell. The Company considered the assets associated with the spin-off to RVI in 2018 as held for sale immediately prior to the distribution and therefore recorded an impairment charge of $14.1 million on the RVI portfolio primarily reflecting an estimate of the costs to sell such assets (Note 14). The Company evaluated its property portfolio and did not identify any other properties that would meet the above-mentioned criteria for held for sale as of December 31, 2019 and 2018. Interest and Real Estate Taxes Interest and real estate taxes incurred relating to the construction, expansion or redevelopment of shopping centers are capitalized and depreciated over the estimated useful life of the building. This includes interest incurred on funds invested in or advanced to unconsolidated joint ventures with qualifying development activities. The Company will cease the capitalization of these costs when construction activities are substantially completed and the property is available for occupancy by tenants. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of interest and taxes until activities are resumed. Interest paid during the years ended December 31, 2019, 2018 and 2017, aggregated $79.5 million, $148.4 million and $194.7 million, respectively, of which $1.3 million, $1.1 million and $1.9 million, respectively, was capitalized. Investments in and Advances to Joint Ventures and Affiliate To the extent that the Company’s cost basis in an unconsolidated joint venture is different from the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in the Company’s share of equity in net income (loss) of the joint venture. Periodically, management assesses whether there are any indicators that the value of the Company’s investments in unconsolidated joint ventures may be impaired. An investment is impaired only if the Company’s estimate of the fair value of the investment is less than the carrying value of the investment and such difference is deemed to be other than temporary. Investment impairment charges create a basis difference between the Company’s share of accumulated equity as compared to the investment balance of the respective unconsolidated joint venture. The Company allocates the aggregate impairment charge to each of the respective properties owned by the joint venture on a relative fair value basis and amortizes this basis differential as an adjustment to the equity in net income (loss) recorded by the Company over the estimated remaining useful lives of the underlying assets. The RVI Preferred Shares are classified as Investment in and Advances to Affiliate on the Company’s consolidated balance sheets. The RVI Preferred Shares have a liquidation and dividend preference over the common stock, but do not have any substantive voting rights, with limited exceptions, or conversion rights and do not have a stated coupon. The RVI Preferred Shares are carried at cost, subject to adjustments in certain circumstances, and will be periodically evaluated for impairment. Dividend payments up to $190 million received by SITE Preferred Equity Interests At December 31, 2019, the Company had net preferred equity interests of $112.6 million recorded in Investments in and Advances to Joint Ventures (Note 3). The Company evaluates the collectability of both the principal and interest on these investments based upon an assessment of the underlying collateral value to determine whether the investment is impaired. As the underlying collateral for the investments is real estate investments, the same valuation techniques are used to value the collateral as those used to determine the fair value of real estate investments for impairment purposes as disclosed above. In addition, the Company performs an additional present value of cash flows for the underlying collateral value that is probability-weighted based upon management’s estimate of the repayment timing. The preferred equity interests are considered impaired if the Company’s estimate of the fair value of the underlying collateral is less than the carrying value of the preferred equity interests. In 2019, 2018 and 2017, based upon the results of the impairment assessment, the Company recorded an aggregate valuation allowance of $15.5 million, $11.4 million and $61.0 million, respectively, related to both of its preferred equity investments to reflect the risk that the securities are not repaid in full in advance of the Company’s redemption rights in 2021 and 2022 (Note 14). Interest income on the impaired investments is recognized on a cash basis. The Company will continue to monitor the investments and related valuation allowance, which could be increased or decreased in future periods, as appropriate. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company maintains cash deposits with major financial institutions, which from time to time may exceed federally insured limits. The Company periodically assesses the financial condition of these institutions and believes that the risk of loss is minimal. Restricted Cash Restricted cash represents amounts on deposit with financial institutions primarily for debt service payments, real estate taxes, capital improvements and operating reserves as required pursuant to the respective loan agreement. For purposes of the Company’s consolidated statements of cash flows, changes in restricted cash are aggregated with cash and cash equivalents. Accounts Receivable The Company makes estimates of the collectability of its accounts receivable related to base rents, including straight-line rentals, expense reimbursements and other revenue or income. Upon adoption of Topic 842, rental income for the periods beginning on or after January 1, 2019, has been reduced for amounts the Company believes are not probable of being collected. The Company analyzes accounts receivable, tenant credit worthiness and current economic trends when evaluating the probability of collection. In addition, with respect to tenants in bankruptcy, the Company makes estimates of the expected recovery of pre-petition and post-petition claims in assessing the probability of collection of the related receivable. The time to resolve these claims may exceed one year. These estimates have a direct impact on the Company’s earnings because once the amount is not considered probable of being collected, earnings are reduced by a corresponding amount until the receivable is collected. Accounts receivable, excluding straight-line rents receivable, do not include estimated amounts not probable of being collected of $1.0 million and $3.2 million at December 31, 2019 and 2018, respectively. Accounts receivable are expected to be collected within one year. The 2019 amount relates to reserves on contract disputes. At December 31, 2019 and 2018, straight-line rents receivable, net of a provision for uncollectible amounts of $2.8 million and $2.3 million, respectively, aggregated $31.2 million and $31.1 million, respectively. Notes Receivable Notes receivable include certain loans that are held for investment and are generally collateralized by real estate-related investments and may be subordinate to other senior loans. Loans receivable are recorded at stated principal amounts or at initial investment. The Company defers loan origination and commitment fees, net of origination costs, and amortizes them over the term of the related loan. The Company evaluates the collectability of both principal and interest on each loan based on an assessment of the underlying collateral value to determine whether it is impaired, and not by the use of internal risk ratings. A loan loss reserve is recorded when, based upon current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value of the underlying collateral. As the underlying collateral for a majority of the notes receivable is real estate-related investments, the same valuation techniques are used to value the collateral as those used to determine the fair value of real estate investments for impairment purposes. Given the small number of loans outstanding, all of the Company’s loans are evaluated individually for this purpose. Interest income on performing loans is accrued as earned. Interest income on non-performing loans is recognized on a cash basis. Recognition of interest income on an accrual basis on non-performing loans is resumed when it is probable that the Company will be able to collect amounts due according to the contractual terms. Deferred Charges External costs and fees incurred in obtaining indebtedness are included in the Company’s consolidated balance sheets as a direct deduction from the related debt liability. Debt issuance costs related to the Company’s revolving credit facilities remain classified as an asset on the consolidated balance sheets as these costs are, at the outset, not associated with an outstanding borrowing. The aggregate costs are amortized over the terms of the related debt agreements. Such amortization is reflected in Interest Expense in the Company’s consolidated statements of operations. Treasury Shares The Company’s share repurchases are reflected as treasury shares utilizing the cost method of accounting and are presented as a reduction to consolidated shareholders’ equity. Reissuances of the Company’s treasury shares at an amount below cost are recorded as a charge to paid-in capital due to the Company’s cumulative distributions in excess of net income. Revenue Recognition The Company adopted the accounting guidance for revenue from contracts with customers (“Topic 606”) on January 1, 2018, using the modified retrospective approach, and therefore, the 2017 comparative information has not been adjusted. The guidance has been applied to contracts that were not completed as of the date of initial application, January 1, 2018. Most significantly for the real estate industry, leasing transactions are not within the scope of the standard. A majority of the Company’s tenant-related revenue is recognized pursuant to lease agreements and is governed by the leasing guidance. Historically, the majority of the Company’s lease commission revenue was recognized 50% upon lease execution and 50% upon tenant rent commencement. Upon adoption of Topic 606, lease commission revenue is generally recognized in its entirety upon lease execution. Rental Income • Fixed lease payments, which include fixed payments associated with expense reimbursements from tenants for common area maintenance, taxes and insurance from tenants in shopping centers, are recognized on a straight-line basis over the non-cancelable term of the lease, which generally ranges from one month to 30 years, and include the effects of applicable rent steps and abatements. • Variable lease payments, which include percentage and overage income, recognized after a tenant’s reported sales have exceeded the applicable sales breakpoint set forth in the applicable lease. • Variable lease payments associated with expense reimbursements from tenants for common area maintenance, taxes, insurance and other property operating expenses, based upon the tenant’s lease provisions, which are recognized in the period the related expenses are incurred. • Lease termination payments, which are recognized upon the effective termination of a tenant’s lease when the Company has no further obligations under the lease. • Ancillary and other property-related rental payments, primarily composed of leasing vacant space to temporary tenants, kiosk income, and parking income, which are recognized in the period earned. Business Interruption Income The Company will record revenue for covered business interruption in the period it determines that it is probable it will be compensated and the applicable contingencies with the insurance company are resolved. This income recognition criteria will likely result in business interruption insurance recoveries being recorded in a period subsequent to the period the Company experiences lost revenue from the damaged properties. Revenues from Contracts with Customers The Company’s revenues from contracts with customers generally relate to asset and property management fees, leasing commission and development fees. These revenues are derived from the Company’s management agreements with RVI and unconsolidated joint ventures and, in the case of unconsolidated joint ventures, are recognized to the extent attributable to the unaffiliated ownership in the unconsolidated joint venture to which it relates. Termination rights under these contracts vary by contract but generally include termination for cause by either party or due to sale of the property. Asset and Property Management Fees Asset and property management services include property maintenance, tenant coordination, accounting and financial services. Asset and property management services represent a series of distinct daily services. Accordingly, the Company satisfies the performance obligation as services are rendered over time. The Company is compensated for property management services through a monthly management fee earned based on a specified percentage of the monthly rental receipts generated from the property under management. The Company is compensated for asset management services through a fee that is billed to the customer monthly and recognized as revenue monthly as the services are rendered, based on a percentage of aggregate asset value or capital contributions for assets under management at the end of the quarter. The asset management fee under the RVI external management agreement is paid monthly based on the initial aggregate appraised value of the RVI properties. RVI property management fees are paid monthly based on the average gross revenue collected during the three months immediately preceding the most recent December 31 or June 30. Property Leasing The Company provides strategic advice and execution to third parties, including RVI and certain joint ventures, in connection with the leasing of retail space. The Company is compensated for services in the form of a commission. The commission is paid upon the occurrence of certain contractual events that may be contingent. For example, a portion of the commission may be paid upon execution of the lease by the tenant, with the remaining paid upon occurrence of another future contingent event (e.g., payment of first month’s rent or tenant move-in). The Company typically satisfies its performance obligation at a point in time when control is transferred, generally, at the time of the first contractual event where there is a present right to payment. The Company looks to history, experience with a customer and deal-specific considerations to support its judgment that the second contingency will be met. Therefore, the Company typically accelerates the recognition of revenue associated with the second contingent event (if any) to the point in time when control of its service is transferred. Development Services Development services consist of construction management oversight services such as hiring general contractors, reviewing plans and specifications, performing inspections, reviewing documentation and accounting services. These services represent a series of distinct services and are recognized over time as services are rendered. The Company is compensated monthly for services based on percentage of aggregate amount spent on the construction during the month. Disposition Fees The Company receives disposition fees equal to 1% of the gross sales price of each RVI asset sold. The Company is compensated at the time of the closing of the sale transaction. Contract Assets Contract assets represent assets for revenue that have been recognized in advance of billing the customer and for which the right to bill is contingent upon something other than the passage of time. This is common for contingent portions of commissions. The portion of payments retained by the customer until the second contingent event is not considered a significant financing component because the right to payment is expected to become unconditional within one year or less. Contract assets are transferred to receivables when the right to payment becomes unconditional. General and Administrative Expenses General and administrative expenses include certain internal leasing and legal salaries and related expenses associated with the re-leasing of existing space, which are charged to operations as incurred. Equity-Based Plans Compensation cost relating to stock-based payment transactions classified as equity is recognized in the financial statements based upon the grant date fair value. The forfeiture rate is based on actual expectations. Under the anti-dilution provisions of the Company’s equity incentive plan, stock-based compensation was adjusted as of the spin-off of RVI, effective July 1, 2018, as determined by the Company’s compensation committee. The adjustments were made so as to retain the same intrinsic value immediately after the spin-off to that the award had immediately prior to the spin-off. Certain awards are dual-indexed to both the Company and RVI results and accounted for as liability awards and marked to fair value on a quarterly basis. Stock-based compensation cost recognized by the Company was $9.2 million, $7.7 million and $11.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. These amounts include $1.4 million and $5.5 million of expense related to the accelerated vesting of awards due to employee separations in 2018 and 2017, respectively. This cost is included in General and Administrative Expenses in the Company’s consolidated statements of operations. Income Taxes The Company has made an election to qualify, and believes it is operating so as to qualify, as a real estate investment trust (“REIT”) for federal income tax purposes. Accordingly, the Company generally will not be subject to federal income tax, provided that it makes distributions to its shareholders equal to at least the amount of its REIT taxable income as defined under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and continues to satisfy certain other requirements. In connection with the REIT Modernization Act, the Company is permitted to participate in certain activities and still maintain its qualification as a REIT, so long as these activities are conducted in entities that elect to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal and state income taxes on the income from these activities. The Tax Cuts and Jobs Act was enacted on December 22, 2017. It included numerous law changes for tax years beginning after December 31, 2017, some of which are applicable to REITs. The changes did not have a material impact on the Company’s financial statements. In the normal course of business, the Company or one or more of its subsidiaries is subject to examination by federal, state and local tax jurisdictions as well as certain jurisdictions outside the United States, in which it operates, where applicable. The Company expects to recognize interest and penalties related to uncertain tax positions, if any, as income tax expense. For the three years ended December 31, 2019, the Company recognized no material adjustments regarding its tax accounting treatment for uncertain tax provisions. As of December 31, 2019, the tax years that remain subject to examination by the major tax jurisdictions under applicable statutes of limitations are generally the year 2016 and forward. Deferred Tax Assets The Company accounts for income taxes related to its taxable REIT subsidiary (“TRS”) under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the income statement in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes it is more likely than not that these assets will be realized. A valuation allowance is recorded against the deferred tax assets when the Company determines that an uncertainty exists regarding their realization, which would increase the provision for income taxes. In making such determination, the Company considers all available positive and negative evidence, including forecasts of future taxable income, the reversal of other existing temporary differences, available net operating loss carryforwards, tax planning strategies and recent results of operations. Several of these considerations require assumptions and significant judgment about the forecasts of future taxable income and must be consistent with the plans and estimates that the Company is utilizing to manage its business. As a result, to the extent facts and circumstances change, an assessment of the need for a valuatio

Revenue From Contract With Customer [Abstract]
Revenue Recognition	2. Revenue Recognition The Company adopted ASC 606, Revenue from Contracts with Customers, on January 1, 2018. For the real estate industry, leasing transactions fall under Topic 842 (Note 1), which has been adopted at January 1, 2019. Therefore, Fee and Other Income on the consolidated statements of operations was the revenue stream impacted by ASC 606 and includes revenue from contracts with customers and other property-related income, primarily composed of theater income, and is recognized in the period earned. Fee and Other Income is as follows (in thousands): For the Year Ended December 31, 2019 2018 2017 Revenue from contracts: Asset and property management fees $ 42,355 $ 31,751 $ 21,494 Leasing commissions 6,300 6,380 7,138 Development fees 2,019 1,638 1,921 Disposition fees 3,454 2,959 — Credit facility guaranty and refinancing fees 1,860 60 — Total revenue from contracts with customers 55,988 42,788 30,553 Other property income: Other 7,694 6,989 6,645 Total fee and other income $ 63,682 $ 49,777 $ 37,198 The aggregate amount of receivables from contracts with customers was $1.4 million and $1.8 million as of December 31, 2019 and 2018, respectively. Contract assets are included in Other Assets, net on the consolidated balance sheets.

(C) The difference between the Company’s share of net income, as reported above, and the amounts included in the Company’s consolidated statements of operations is attributable to the amortization of basis differentials, unrecognized preferred PIK, the recognition of deferred gains, differences in gain (loss) on sale of certain assets recognized due to the basis differentials and other than temporary impairment charges. Revenues earned by the Company related to all of the Company’s unconsolidated joint ventures and interest income on its preferred interests in the BRE DDR Joint Ventures (as defined below) are as follows (in millions): For the Year Ended December 31, 2019 2018 2017 Revenue from contracts: Asset and property management fees $ 19.7 $ 18.8 $ 21.4 Development fees, leasing commissions and other 5.2 6.9 9.1 24.9 25.7 30.5 Other: Interest income 16.7 19.0 25.9 Other 3.2 2.6 2.8 19.9 21.6 28.7 $ 44.8 $ 47.3 $ 59.2 The Company’s joint venture agreements generally include provisions whereby each partner has the right to trigger a purchase or sale of its interest in the joint venture or to initiate a purchase or sale of the properties after a certain number of years or if either party is in default of the joint venture agreements. The Company is not obligated to purchase the interests of its outside joint venture partners under these provisions. Disposition of Shopping Centers The Company’s joint ventures sold six, 40 and 15 shopping centers and land for an aggregate sales price of $356.3 million, $786.5 million and $545.6 million, respectively, of which the Company’s share of the gain on sale was $4.2 million, $13.7 million and $5.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. Included in the 2018 shopping center dispositions were three assets sold by two of the Company’s unconsolidated joint ventures to the Company for $35.1 million (Note 5). BRE DDR Joint Ventures The Company’s two unconsolidated investments with The Blackstone Group L.P. (“Blackstone”), BRE DDR Retail Holdings III (“BRE DDR III”) and BRE DDR Retail Holdings IV (“BRE DDR IV” and, together with BRE DDR III, the “BRE DDR Joint Ventures”), have substantially similar terms. An affiliate of Blackstone is the managing member and effectively owns 95% of the common equity of each of the two BRE DDR Joint Ventures, and consolidated affiliates of SITE Centers effectively own the remaining 5%. The Company provides leasing and property management services to all of the joint venture properties. The Company cannot be removed as the property and leasing manager until the preferred equity, as discussed below, is redeemed in full (except for certain specified events). The Company’s preferred interests are entitled to certain preferential cumulative distributions payable out of operating cash flows and certain capital proceeds pursuant to the terms and conditions of the preferred investments. The preferred distributions are recognized as Interest Income within the Company’s consolidated statements of operations and are classified as a note receivable in Investments in and Advances to Joint Ventures on the Company’s consolidated balance sheets. The preferred investments have an annual distribution rate of 8.5% including any deferred and unpaid preferred distributions. Blackstone has the right to defer up to 2.0% of the 8.5% preferred fixed distributions as a payment in kind (“PIK”) distribution. Blackstone has made this PIK deferral election since the formation of both joint ventures. The cash portion of the preferred fixed distributions is generally payable first out of operating cash flows and is current for both BRE DDR Joint Ventures. The Company has no expectation that the cash portion of the preferred fixed distribution will become impaired. As a result of the valuation allowances recorded, the Company no longer recognizes as interest income the 2.0% PIK. Although Blackstone has the right to change its payment election, the Company expects future preferred distributions to continue to include the PIK component. The recognition of the PIK interest income will be reevaluated based upon any future adjustments to the aggregate valuation allowance, as appropriate. The unpaid preferred investment (and any accrued distributions) is payable (1) at Blackstone’s option, in whole or in part, subject to early redemption premiums in certain circumstances during the first three years of the joint ventures; (2) at varying equity sharing levels (determined according to the joint venture’s debt service coverage ratio) with the common members, upon a sale of properties over a certain threshold; (3) at SITE Centers’ option after seven years (2021 for BRE DDR III and 2022 for BRE DDR IV) and (4) upon the incurrence of additional indebtedness by the joint ventures in excess of a certain threshold. Specifically, for BRE DDR III, based upon the cumulative asset sales through December 31, 2019, and the joint venture’s debt service coverage ratio at December 31, 2019, future net asset sale proceeds are expected to be allocated 52.9% to the preferred member and 47.1% to the common equity. For BRE DDR IV, based on the joint venture’s debt service coverage ratio as of December 31, 2019, 100% of the future asset sale proceeds generated are expected to be available to repay the preferred member. As of December 31, 2019, the Company has a valuation allowance recorded on each of the BRE DDR III and BRE DDR IV preferred investment interests on a net basis, as described below. An aggregate valuation allowance adjustment was recorded of $15.5 million, $11.4 million and $61.0 million, for the years ended December 31, 2019, 2018 and 2017, respectively. Adjustments to the valuation allowance are recorded as Reserve of Preferred Equity Interests on the Company’s consolidated statements of operations. The Company reassesses the aggregate valuation allowance quarterly based upon actual timing and values of recent property sales as well as current market assumptions. The valuation techniques used to value the collateral include discounted cash flow analysis on the expected cash flows of each asset, as well as the income capitalization approach considering prevailing market capitalization rates, analysis of recent comparable sales transactions, actual sales negotiations and bona fide purchase offers received from third parties. Additionally, the managing member of the two joint ventures exercises significant influence over the timing of asset sales. As a result, the investments were impaired to reflect the risk that the securities are not repaid in full in advance of the Company’s redemption rights in 2021 and 2022. The Company will continue to monitor the investments and related valuation allowance, which could be increased or decreased in future periods, as appropriate. As discussed above, the preferred 8.5% distribution rate has two components, a cash interest rate of 6.5% and an accrued PIK of 2.0%. As a result of the valuation allowances recorded, the Company no longer recognizes as interest income the 2.0% PIK. (The accrued PIK aggregated $17.3 million and $12.2 million at December 31, 2019 and 2018, respectively). The recognition of the PIK interest income will be re-evaluated based upon any future adjustments to the aggregate valuation allowance, as appropriate. The preferred investments are summarized as follows (in millions, except properties owned): Preferred Investment (Principal) Redemption Date Initial December 31, 2019 Valuation Allowance Net of Reserve Properties Owned at December 31, 2019 BRE DDR III 2021 $ 300.0 $ 132.4 $ (78.2 ) $ 54.2 13 BRE DDR IV 2022 82.6 64.0 (9.7 ) 54.3 5 $ 382.6 $ 196.4 $ (87.9 ) $ 108.5 All transactions with the Company’s equity affiliates are described above.

Investment In and Advances to Affiliate In connection with the spin-off of RVI, RVI issued the RVI Preferred Shares to the Company, which are noncumulative and have no mandatory dividend rate. The RVI Preferred Shares rank, with respect to dividend rights, and rights upon liquidation, dissolution or winding up of RVI, senior in preference and priority to RVI’s common shares and any other class or series of RVI’s capital stock. Subject to the requirement that RVI distribute to its common shareholders the minimum amount required to be distributed with respect to any taxable year in order for RVI to maintain its status a s a REIT and to avoid U.S. federal income taxes, the RVI Preferred Shares are entitled to a dividend preference for all dividends declared on RVI’s capital stock at any time up to a “preference amount” equal to $ 190 million in the aggregate, which amount may increase by up to an additional $ 10 million if the aggregate gross proceeds of RVI’s asset sales subsequent to July 1, 2018 exceed $ 2.0 billion. Notwithstanding the foregoing, the RVI Preferred Shares are entitled to receive dividends only when, as and if declared by RVI’s Board of Directors and RVI’s ability to pay dividends is subject to any restrictions set forth in the terms of its indebtedness. Upon payment to SITE Centers of aggregate dividends on the RVI Preferred Shares equaling the maximum preference amount of $ 200 million, RVI is required to redeem the RVI Preferred Shares for $ 1.00 per share. The RVI Preferred Shares are subject to mandatory redemption in certain other circumstances. The RVI Preferred Shares are included in Investment in and Advances to Affiliate in the Company’s consolidated balance sheets.

Leases [Abstract]
Leases	7. Leases Lessee The Company is engaged in the operation of shopping centers that are either owned or, with respect to certain shopping centers, operated under long-term ground leases that expire at various dates through 2070. The Company also leases office space in the ordinary course of business under lease agreements that expire at various dates through 2029. Certain of the lease agreements include variable payments for reimbursement of common area expenses. The Company determines if an arrangement is a lease at inception. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not include an implicit rate, the Company used its incremental borrowing rate based on the information available at the commencement date of the standard in determining the present value of lease payments. For each lease, the Company utilized a market-based approach to estimate the incremental borrowing rate (“IBR”), which required significant judgment. The Company estimated base IBRs based on an analysis of (i) yields on the Company’s outstanding public debt, as well as comparable companies, (ii) observable mortgage rates and (iii) unlevered property yields and discount rates. The Company applied adjustments to the base IBRs to account for full collateralization and lease term. Operating lease ROU assets also include any lease payments made. The Company has options to extend certain of the ground and office leases; however, these options were not considered as part of the lease term when calculating the lease liability, as they were not reasonably certain to be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Operating lease ROU assets and operating lease liabilities are included in the Company’s consolidated balance sheet as follows (in thousands): Classification December 31, 2019 Operating Lease ROU Assets Other Assets, Net $ 21,792 Operating Lease Liabilities Accounts Payable and Other Liabilities $ 40,725 Operating lease expenses, including straight-line expense, are included in Operating and Maintenance Expense for the Company’s ground leases and General and Administrative for its office leases are as follows (in thousands): Classification December 31, 2019 Operating and Maintenance $ 3,495 General and Administrative (A) 2,837 Total lease costs $ 6,332 (A) Includes short-term leases and variable lease costs, which are immaterial.

In 2019, the Company amended and restated its unsecured revolving credit facility with a syndicate of financial institutions, arranged by Wells Fargo Securities, LLC, J.P. Morgan Chase Bank, N.A., Citizens Bank, N.A., RBC Capital Markets and U.S. Bank National Association (the “Unsecured Credit Facility”). The Unsecured Credit Facility provides for borrowings of up to $950 million if certain financial covenants are maintained, and an accordion feature for expansion of availability up to $1.45 billion, provided that new or existing lenders agree to the existing terms of the facility and increase their commitment level, and was amended to extend the maturity date to January 2024, subject to two six-month options to extend the maturity to January 2025 upon the Company’s request (subject to satisfaction of certain conditions) and to reduce the interest rate margins applicable to drawn amounts. The Unsecured Credit Facility includes a competitive bid option on periodic interest rates for up to 50% of the facility. The Unsecured Credit Facility also provides for an annual facility fee, which was 20 basis points on the entire facility at December 31, 2019. In 2019, the Company also amended its $20 million unsecured revolving credit facility with PNC Bank, National Association (“PNC”, the “PNC Facility” and, together with the Unsecured Credit Facility, the “Revolving Credit Facilities”) to reflect substantially the same terms as those contained in the Unsecured Credit Facility. Additionally, the Company has the Company The Company’s borrowings under the Revolving Credit Facilities bear interest at variable rates at the Company’s election, based on either LIBOR, plus a specified spread (0.90% at December 31, 2019) or the Alternative Base Rate, as defined in the respective facility, plus a specified spread (0% at December 31, 2019). The specified spreads vary depending on the Company’s long-term senior unsecured debt rating from Moody’s Investors Service, Inc., S&P Global Ratings, Fitch Investor Services, Inc. and their successors. The Company is required to comply with certain covenants under the Revolving Credit Facilities relating to total outstanding indebtedness, secured indebtedness, value of unencumbered real estate assets and fixed charge coverage. The Company was in compliance with these financial covenants at December 31, 2019 and 2018.

All other interest rates presented are a weighted average of the outstanding debt. Interest rate on variable-rate debt was calculated using the base rate and spreads in effect at December 31, 2019 and 2018 . (B) Effective interest rates ranged from 3.5% to 4.8% at December 31, 2019. Senior Notes The Company’s various fixed-rate senior notes have interest coupon rates that averaged 4.2% per annum at December 31, 2019 and 2018. The senior notes may be redeemed based upon a yield maintenance calculation. The fixed-rate senior notes were issued pursuant to indentures that contain certain covenants, including limitation on incurrence of debt, maintenance of unencumbered real estate assets and debt service coverage. The covenants also require that the cumulative dividends declared or paid from December 31, 1993, through the end of the current period cannot exceed Funds From Operations (as defined in the agreement) plus an additional $20.0 million for the same period unless required to maintain REIT status. Interest is paid semiannually in arrears. At December 31, 2019 and 2018, the Company was in compliance with all of the financial covenants under the indentures. Term Loan The Company maintains a term loan with Wells Fargo Bank, National Association, as administrative agent, and PNC and KeyBank National Association, as syndication agents (the “Term Loan”). In 2019, the principal amount of this Term Loan was increased to $100.0 million. The Term Loan accrues interest at a variable rate based on LIBOR as defined in the loan agreement plus a specified spread based on the Company’s long-term senior unsecured debt rating (1.0% at December 31, 2019). The maturity date is January 2023. The Company may increase the amount of the facility provided that lenders agree to certain terms.

Financial Instruments and Fair Value Measurements	10. Financial Instruments and Fair Value Measurements The following methods and assumptions were used by the Company in estimating fair value disclosures of financial instruments: Other Fair Value Instruments Investments in unconsolidated joint ventures are considered financial assets. See discussion of fair value considerations of joint venture investments in Note 14. Cash and Cash Equivalents, Restricted Cash, Accounts Receivable, Accounts Payable, Accrued Expenses and Other Liabilities The carrying amounts reported in the Company’s consolidated balance sheets for these financial instruments approximated fair value because of their short-term maturities. Debt The fair market value of senior notes is determined using the trading price of the Company’s public debt. The fair market value for all other debt is estimated using a discounted cash flow technique that incorporates future contractual interest and principal payments and a market interest yield curve with adjustments for duration, optionality and risk profile, including the Company’s non-performance risk and loan to value. The Company’s senior notes and all other debt are classified as Level 2 and Level 3, respectively, in the fair value hierarchy. Considerable judgment is necessary to develop estimated fair values of financial instruments. Accordingly, the estimates presented are not necessarily indicative of the amounts the Company could realize on disposition of the financial instruments. Debt instruments with carrying values that are different from estimated fair values are summarized as follows (in thousands): December 31, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Senior Notes $ 1,647,963 $ 1,744,581 $ 1,646,007 $ 1,639,827 Revolving Credit Facilities and term loan 104,460 105,084 149,655 150,533 Mortgage Indebtedness 94,874 96,276 88,743 89,228 $ 1,847,297 $ 1,945,941 $ 1,884,405 $ 1,879,588

Commitments and Contingencies	11. Commitments and Contingencies Hurricane Loss In 2017, Hurricane Maria made landfall in Puerto Rico. At June 30, 2018, RVI owned 12 assets in Puerto Rico, aggregating 4.4 million square feet of Company-owned gross leasable area (“GLA”). These assets were included in the spin-off of RVI (Note 1). One of the 12 assets, Plaza Palma Real, was severely damaged and was not operational following the storm, except for two anchor tenants and a few other tenants. The other 11 assets sustained varying degrees of damage, consisting primarily of roof and HVAC system damage and water intrusion. In connection with the spin-off of RVI in July 2018, insurance proceeds from Hurricane Maria were largely allocated to RVI pursuant to the terms of the agreement governing the separation of the Company and RVI. Legal Matters The Company and its subsidiaries are subject to various legal proceedings, which, taken together, are not expected to have a material adverse effect on the Company. The Company is also subject to a variety of legal actions for personal injury or property damage arising in the ordinary course of its business, most of which are covered by insurance. While the resolution of all matters cannot be predicted with certainty, management believes that the final outcome of such legal proceedings and claims will not have a material adverse effect on the Company’s liquidity, financial position or results of operations. Separation Charges The Company recorded separation charges aggregating $4.6 million and $17.9 million in 2018 and 2017, respectively, which are included in General and Administrative Expenses. Commitments and Guaranties In conjunction with the redevelopment and expansion of various shopping centers, the Company has entered into agreements with general contractors for the construction or redevelopment of shopping centers aggregating approximately $8.1 million as of December 31, 2019. At December 31, 2019, the Company had letters of credit outstanding of $13.2 million. The Company has not recorded any obligation associated with these letters of credit. The majority of the letters of credit are collateral for existing indebtedness and other obligations of the Company.

These OP Units, issued to different partnerships, are exchangeable at the election of the OP Unit holder and, under certain circumstances at the option of the Company, exchangeable into an equivalent number of the Company’s common shares or for the equivalent amount of cash. Most of these OP Units are subject to registration rights agreements covering shares equivalent to the number of OP Units held by the holder if the Company elects to settle in its common shares. The OP Units are classified on the Company’s consolidated balance sheets as Non-Controlling Interests. Common Shares In 2019, the Company issued 13.225 million common shares resulting in net proceeds of $194.6 million. The Company’s common shares have a $0.10 per share par value. Common share dividends declared were as follows: For the Year Ended December 31, 2019 2018 2017 Common share dividends declared per share $ 0.80 $ 1.16 $ 1.52 Common Shares in Treasury In 2018, the Company’s Board of Directors authorized a $100 million common share repurchase program. In 2019 and 2018, the Company repurchased 1.2 million shares and 3.1 million shares at an aggregate cost of $14.1 million and $36.3 million, respectively. These shares were recorded as Treasury Shares on the Company’s consolidated balance sheets. Preferred Shares In 2019, the Company redeemed all $200.0 million aggregate liquidation preference of its 6.50% Class J Cumulative Redeemable Preferred Shares (the “Class J Preferred Shares”) at a redemption price of $500 per Class J Preferred Share (or $25.00 per depositary share) plus accrued and unpaid dividends of $3.7917 per Class J Preferred Share (or $0.1896 per depositary share). The Company recorded a non-cash charge of approximately $7.2 million to net income attributable to common shareholders, which represents the difference between the redemption price and the carrying amount immediately prior to redemption, which was recorded to additional paid in capital upon original issuance. The depositary shares, representing the Class A Cumulative Redeemable Preferred Shares (“Class A Shares”) and the Class K Cumulative Redeemable Preferred Shares (“Class K Shares”), represent 1/20 of a Class A Share and Class K Share, respectively, and have a liquidation value of $500 per share. The Class K depositary shares are redeemable by the Company. The Class A depositary shares are not redeemable by the Company prior to June 5, 2022, except in certain circumstances relating to the preservation of the Company’s status as a REIT. The Company’s authorized preferred shares consist of the following: • 750,000 • 750,000 • 2,000,000

Asset Impairment Charges [Abstract]
Impairment Charges and Reserves	14. Impairment Charges and Reserves The Company recorded impairment charges and reserves based on the difference between the carrying value of the assets or investments and the estimated fair market value as follows (in millions): For the Year Ended December 31, 2019 2018 2017 Assets marketed for sale (A) $ 0.6 $ 5.8 $ 58.2 Undeveloped land (A) 2.8 0.9 15.1 Assets included in the spin-off of RVI (A) — 62.6 267.2 Reserve of preferred equity interests (B) 15.5 11.4 61.0 Total impairment charges $ 18.9 $ 80.7 $ 401.5 (A) In 2019, impairments recorded were triggered by indicative bids received. In 2018 and 2017, impairments recorded were triggered by changes in asset hold-period assumptions and/or expected future cash flows in conjunction with the change in its executive management team and strategic direction to increase the volume of asset sales to accelerate progress on its deleveraging goal. (B) As a result of an aggregate valuation allowance on its preferred equity interests in the BRE DDR Joint Ventures (Note 3). Items Measured at Fair Value on a Non-Recurring Basis The Company is required to assess the fair value of certain impaired consolidated and unconsolidated joint venture investments. The valuation of impaired real estate assets and investments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each asset, as well as the income capitalization approach considering prevailing market capitalization rates, analysis of recent comparable sales transactions, actual sales negotiations and bona fide purchase offers received from third parties and/or consideration of the amount that currently would be required to replace the asset, as adjusted for obsolescence. In general, the Company considers multiple valuation techniques when measuring fair value of an investment. However, in certain circumstances, a single valuation technique may be appropriate. For operational real estate assets, the significant valuation assumptions included the capitalization rate used in the income capitalization valuation, as well as the projected property net operating income and expected hold period. For projects under development or not at stabilization, the significant assumptions included the discount rate, the timing and the estimated costs for the construction completion and project stabilization, projected net operating income and the exit capitalization rate. For the valuation of the preferred equity interests, the significant assumptions used in the discounted cash flow analysis included the discount rate, projected net operating income, the timing of the expected redemption and the exit capitalization rates. For investments in unconsolidated joint ventures, the Company also considered the valuation of any underlying joint venture debt and terms of the joint venture agreement. These valuations were calculated based on market conditions and assumptions made by management at the time the valuation adjustments and impairments were recorded, which may differ materially from actual results if market conditions or the underlying assumptions change. The following table presents information about the Company’s impairment charges and reserves on both financial and nonfinancial assets that were measured on a fair value basis for the years ended December 31, 2019, 2018 and 2017. The table also indicates the fair value hierarchy of the valuation techniques used by the Company to determine such fair value (in millions).

Postemployment Benefits [Abstract]
Stock-Based Compensation Plans and Employee Benefits	15. Stock-Based Compensation Plans and Employee Benefits Spin-off Adjustments As a result of the spin-off of RVI, all equity awards outstanding on July 1, 2018, were adjusted to obtain an equitable modification and to generally preserve their pre-spin intrinsic value pursuant to the anti-dilution provisions of the stock-based compensation plan under which they were issued. The spin-off adjustments are reflected in the tables below and discussed in Note 1. Stock-Based Compensation The Company’s equity-based award plans provide for grants to Company employees and directors of incentive and non-qualified options to purchase common shares, rights to receive the appreciation in value of common shares, awards of common shares subject to restrictions on transfer, awards of common shares issuable in the future upon satisfaction of certain conditions and rights to purchase common shares and other awards based on common shares. Under the terms of the plans, 3.7 million common shares were available for grant under future awards as of December 31, 2019. Stock Options Stock options may be granted at per-share prices not less than fair market value at the date of grant and must be exercised within the maximum contractual term of 10 years thereof. The fair values for option awards granted were estimated at the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions (no option awards were granted in 2019 or 2018): For the Year Ended December 31, 2017 Weighted-average fair value of grants $ 2.07 Risk-free interest rate (range) – Based upon the U.S. Treasury Strip with a maturity date that approximates the expected term of the award 1.8% Dividend yield (range ) – Forecasted dividend yield based on the expected life 5.2% Expected life (range) – Derived by referring to actual exercise experience 4 years Expected volatility (range) – Derived by using a 50/50 blend of implied and historical changes in the Company's historical stock prices over a time frame consistent with the expected life of the award 19.8% The following table reflects the stock option activity: Weighted- Weighted- Average Aggregate Number of Options (Thousands) Average Exercise Price Remaining Contractual Term (Years) Intrinsic Value (Thousands) Balance December 31, 2016 903 $ 38.32 Granted 77 28.86 Exercised (26 ) 14.66 Forfeited (366 ) 44.62 Balance December 31, 2017 588 27.64 Granted — — Spin-off adjustment 139 Exercised (19 ) 9.73 Forfeited (262 ) 32.26 Balance December 31, 2018 446 25.71 Granted — — Exercised (12 ) 9.73 Forfeited (84 ) 25.04 Balance December 31, 2019 350 $ 26.42 4.8 $ — Options exercisable at December 31, 2019 333 $ 26.58 4.7 $ — 2018 368 25.86 4.8 27 2017 398 34.92 4.5 196 The following table summarizes the characteristics of the options outstanding at December 31, 2019: Options Outstanding Options Exercisable Range of Exercise Prices Outstanding at 12/31/19 (Thousands) Weighted-Average Remaining Contractual Life (Years) Weighted-Average Exercise Price Exercisable at 12/31/19 (Thousands) Weighted-Average Exercise Price $0.00 – 13 0.3 $ 16.58 13 $ 16.58 $20.01–$31.11 337 4.9 26.79 320 26.97 350 4.8 $ 26.42 333 $ 26.58 The following table reflects the activity for unvested stock option awards: Options (Thousands) Weighted-Average Grant Date Fair Value Unvested at December 31, 2018 78 $ 2.31 Granted — — Vested (58 ) 2.39 Forfeited (3 ) 2.08 Unvested at December 31, 2019 17 $ 2.07 As of December 31, 2019, all stock option compensation cost was recognized. The following table summarizes the activity of employee stock option exercises that are primarily settled with newly issued common shares or with treasury shares, if available (in millions): For the Year Ended December 31, 2019 2018 2017 Cash received for exercise price $ 0.1 $ 0.2 $ 0.4 Intrinsic value — 0.1 0.2 Restricted Share Units The Board of Directors approved grants to officers of the Company of restricted common share units (“RSUs”) of 0.3 million in 2019, 0.3 million in 2018 and 0.4 million in 2017. The restricted stock grants generally vest in equal annual amounts over a three- to four-year Performance-Based Restricted Share Units (PRSUs) In 2019 and 2018, the Board of Directors approved grants to the chief executive officer, chief operating officer and former chief financial officer of PRSUs covering a “target” number of shares, subject to performance periods beginning on March 1, 2019 and March 1, 2018, respectively, and ending on February 28, 2022 and February 28, 2021, respectively. In 2017, the Board of Directors approved grants to the chief executive officer, chief operating officer and former chief financial officer of PRSUs covering a “target” number of shares, subject to one-year, two-year and three-year performance periods beginning on March 1, 2017. The payout of the PRSUs will vary based on relative total shareholder return performance measured over the applicable performance period, with the ultimate payout ranging from a level of 0% of target to a maximum level of 200% of target (subject to reduction by one-third in the event that SITE Centers’ absolute total shareholder return during the applicable performance period is negative). For the PRSUs in which the performance period ended in February 2019 and February 2018, no shares were granted. The 2019, 2018 and 2017 grants have a fair value at the date of grant aggregating $5.6 million, $4.7 million and $3.9 million, respectively, to be amortized ratably over the performance period ending three years from the date of grant. The 2019 grant is accounted for as an equity award. The 2017 and 2018 grants are accounted for as liability awards due to the RVI spin-off. Under the anti-dilution provisions of the Company’s equity incentive plan and the respective PRSU award agreement, the PRSUs issued in 2017 and 2018 were adjusted as of the spin-off of RVI, effective July 1, 2018, as determined by the Company’s compensation committee. The number of PRSUs was adjusted so as to retain the same intrinsic value immediately after the spin-off that the PRSU awards had immediately prior to the spin-off. In particular, upon consummation of the spin-off of RVI, the 2017 and 2018 PRSU awards were adjusted to: (1) retain the original SITE Centers relative total shareholder return (“RTSR”) peer group; (2) retain the SITE Centers beginning share price used for RTSR purposes and (3) measure ending share price as SITE Centers’ ending price plus RVI’s split-adjusted ending price (with any dividends paid during the performance period deemed reinvested into additional SITE Centers shares). Effective at the date of the spin-off, because these awards are dual-indexed to both the Company’s and RVI’s stock performance, the 2017 and 2018 PRSU awards are accounted for as liability awards and marked to fair value on a quarterly basis. In 2019, the Company recorded a mark-to-market adjustment of $1.9 million in connection with the PRSUs issued primarily in March 2018. The mark-to-market adjustment in 2018 was not material. Summary of Unvested Share Awards The following table reflects the activity for the unvested awards pursuant to all restricted stock grants: Awards (Thousands) Weighted-Average Grant Date Fair Value Unvested at December 31, 2018 561 $ 16.77 Granted 260 13.59 Vested (121 ) 20.23 Forfeited (63 ) 16.27 Unvested at December 31, 2019 637 $ 14.86 As of December 31, 2019, total unrecognized compensation for the restricted awards granted under the plans as summarized above was $12.0 million, which is expected to be recognized over a weighted-average 1.5-year term, which includes the performance-based and time-based vesting periods. Deferred Compensation Plans The Company maintains a 401(k) defined contribution plan covering substantially all of the officers and employees of the Company in accordance with the provisions of the Code. Also, for certain officers, the Company maintains the Elective Deferred Compensation Plan and Equity Deferred Compensation Plan, both non-qualified plans, which permit the deferral of base salaries, commissions and annual performance-based cash bonuses or receipt of restricted shares. In addition, directors of the Company are permitted to defer all or a portion of their fees pursuant to the Directors’ Deferred Compensation Plan, a non-qualified plan. All of these plans were fully funded at December 31, 2019.

Earnings Per Share	16. Earnings Per Share The following table provides a reconciliation of net income (loss) and the number of common shares used in the computations of “basic” earnings per share (“EPS”), which utilizes the weighted-average number of common shares outstanding without regard to dilutive potential common shares, and “diluted” EPS, which includes all such shares (in thousands, except per share amounts). For the Year Ended December 31, 2019 2018 2017 Numerators – Basic and Diluted Net income (loss) $ 101,825 $ 116,105 $ (243,132 ) Plus: (Income) loss attributable to non-controlling interests (1,126 ) (1,671 ) 1,447 Less: Write-off of preferred share original issuance costs (7,176 ) — — Less: Preferred dividends (32,231 ) (33,531 ) (28,759 ) Less: Earnings attributable to unvested shares and OP Units (687 ) (1,137 ) (989 ) Net income (loss) attributable to common shareholders after allocation to participating securities $ 60,605 $ 79,766 $ (271,433 ) Denominators – Number of Shares Basic – Average shares outstanding 183,026 184,528 183,681 Assumed conversion of dilutive securities 228 7 — Diluted – Average shares outstanding 183,254 184,535 183,681 Earnings (Loss) Per Share: Basic $ 0.33 $ 0.43 $ (1.48 ) Diluted $ 0.33 $ 0.43 $ (1.48 ) Basic average shares outstanding do not include restricted shares totaling 0.7 million, 0.7 million and 0.3 million that were not vested at December 31, 2019, 2018 and 2017, respectively (Note 15). The following potentially dilutive securities were considered in the calculation of EPS: • PRSUs issued to certain executives in March 2019 and March 2018 were dilutive and the PRSUs issued in March 2017 were anti-dilutive in the computation of EPS for the year ended December 31, 2019. For the years ended December 31, 2018 and 2017, PRSUs were not considered in the computation of diluted EPS, as the calculation was anti-dilutive. • Options to purchase 0.3 million, 0.4 million and 0.6 million common shares were outstanding at December 31, 2019, 2018 and 2017, respectively (Note 15). These outstanding options were not considered in the computation of diluted EPS for the years ended December 2019 and 2017, as the options were anti-dilutive. • Shares subject to issuance under the Company’s 2016 VSEP were not considered in the computation of diluted EPS for all periods presented, as the calculation was anti-dilutive and no shares were issued under the plan. • The exchange into common shares associated with OP Units was not included in the computation of diluted shares outstanding for all periods presented because the effect of assuming conversion was anti-dilutive (Note 12).

Income Tax Disclosure [Abstract]
Income Taxes	17. Income Taxes The Company elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended, commencing with its taxable year ended December 31, 1993. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that the Company distribute at least 90% of its taxable income to its shareholders. It is management’s current intention to adhere to these requirements and maintain the Company’s REIT status. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes to its shareholders. As the Company distributed sufficient taxable income for each of the three years ended December 31, 2019, no U.S. federal income or excise taxes were incurred. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates and may not be able to qualify as a REIT for the four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain foreign, state and local taxes on its income and property and to federal income and excise taxes on its undistributed taxable income. In addition, the Company has a TRS that is subject to federal, state and local income taxes on any taxable income generated from its operational activity. In order to maintain its REIT status, the Company must meet certain income tests to ensure that its gross income consists of passive income and not income from the active conduct of a trade or business. The Company utilizes its TRS to the extent certain fee and other miscellaneous non-real estate-related income cannot be earned by the REIT. For the years ended December 31, 2019, 2018 and 2017, the Company recorded a net payment of $0.7 million, $1.1 million and $0.7 million, respectively, related to taxes. In 2015, in accordance with temporary legislation of the Puerto Rico Internal Revenue Code, the Company made a voluntary election to prepay taxes related to the built-in gains associated with the real estate assets in Puerto Rico and restructured the ownership of its then 14 assets in Puerto Rico. The net prepaid tax related to the restructuring was $16.8 million. In 2017, the Company sold two of the assets in Puerto Rico and released $1.4 million of the prepaid tax asset. In 2018 and 2017, the Company established a valuation allowance of $4.0 million and $10.8 million, respectively, on the remaining prepaid tax asset triggered by the change in asset hold-period assumptions related to its change in strategic direction for the Puerto Rico properties. In 2018, these assets were assumed by RVI and the associated valuation allowance was written off since this attribute couldn’t be transferred to RVI. The following represents the combined activity of the Company’s TRS (in thousands): For the Year Ended December 31, 2019 2018 2017 Book income before income taxes $ 7,258 $ 1,872 $ 11,180 Current $ 34 $ (430 ) $ 459 Deferred — — — Total income tax (benefit) expense $ 34 $ (430 ) $ 459 The differences between total income tax expense and the amount computed by applying the statutory income tax rate to income before taxes with respect to its TRS activity were as follows (in thousands): For the Year Ended December 31, TRS 2019 2018 2017 Statutory Rate 21 % 21 % 34 % Statutory rate applied to pre-tax income $ 1,524 $ 393 $ 3,801 State tax expense net of federal income tax 27 — 254 Deferred tax expense net of federal income tax — — 724 AMT benefit refund — (430 ) — Permanent items — — (241 ) Deferred tax impact of tax rate change (A) (89 ) 7,350 19,391 Valuation allowance decrease (increase) based on impact of tax rate change (A) 89 (7,350 ) (23,470 ) Valuation allowance decrease – (1,608 ) (672 ) — Other 91 279 — Total expense (benefit) $ 34 $ (430 ) $ 459 Effective tax rate 0.47 % (22.97 %) 4.11 % (A) For the years ended December 31, 2019 and 2018, includes $0.1 million and $7.4 million, respectively, deferred tax impact of state tax rate change, and for the year ended December 31, 2017, includes $19.4 million deferred tax impact of federal tax rate change.

Accounting Policies [Abstract]
Nature of Business	Nature of Business SITE Centers Corp. and its related consolidated real estate subsidiaries (collectively, the “Company” or “SITE Centers”) and unconsolidated joint ventures are primarily engaged in the business of acquiring, owning, developing, redeveloping, expanding, leasing, financing and managing shopping centers. Unless otherwise provided, references herein to the Company or SITE Centers include SITE Centers Corp. and its wholly-owned subsidiaries and consolidated joint ventures. The Company’s tenant base primarily includes national and regional retail chains and local tenants. Consequently, the Company’s credit risk is concentrated in the retail industry. Amounts relating to the number of properties, square footage, tenant and occupancy data, joint ventures interests and estimated project costs are unaudited.
Use of Estimates in Preparation of Financial Statements	Use of Estimates in Preparation of Financial Statements The preparation of financial statements in conformity with generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses during the year. Actual results could differ from those estimates.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the results of the Company and all entities in which the Company has a controlling interest or has been determined to be the primary beneficiary of a variable interest entity (“VIE”). All significant inter-company balances and transactions have been eliminated in consolidation. Investments in real estate joint ventures in which the Company has the ability to exercise significant influence, but does not have financial or operating control, are accounted for using the equity method of accounting. Accordingly, the Company’s share of the earnings (or loss) of these joint ventures is included in consolidated net income (loss). The Company has two unconsolidated joint ventures included in the Company’s joint venture investments that are considered VIEs for which the Company is not the primary beneficiary. The Company’s maximum exposure to losses associated with these VIEs is limited to its aggregate investment, which was $114.0 million and $192.2 million as of December 31, 2019 and 2018, respectively.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified in order to conform with the current period’s presentation. The Company reclassified $13.4 million and $23.9 million of contractual lease payments from Fee and Other Income to Rental Income within total revenues on its consolidated statements of operations for the years ended December 31, 2018 and 2017, respectively, in connection with the adoption of Accounting Standards Update (“ASU”) No. 2016-02— Leases, Topic 842”),
Statements of Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information	Statements of Cash Flows and Supplemental Disclosure of Non-Cash Investing and Financing Information Non-cash investing and financing activities are summarized as follows (in millions): For the Year Ended December 31, 2019 2018 2017 Accounts payable related to construction in progress $ 11.0 $ 9.3 $ 13.4 Mortgage assumed, shopping center acquisition 9.1 — — Contribution of net assets to RVI — 663.4 — Write-off of preferred share original issuance costs (Note 12) 7.2 — — Dividends declared, but not paid 44.0 45.3 78.5 Assumption of buildings due to ground lease terminations — 2.2 8.6 Land acquired by minority interest partner — 2.3 — Conversion of Operating Partnership Units — 0.9 — Receivable and reduction of real estate assets, net – hurricane — — 65.9
Real Estate	Real Estate Real estate assets, which include construction in progress and undeveloped land, are stated at cost less accumulated depreciation. Depreciation and amortization is recorded on a straight-line basis over the estimated useful lives of the assets as follows: Buildings Useful lives, ranging from 31.5 to 40 years Building improvements and fixtures Useful lives, ranging from 5 to 20 years Tenant improvements Shorter of economic life or lease terms The Company periodically assesses the useful lives of its depreciable real estate assets and accounts for any revisions, which are not material for the periods presented, prospectively. Expenditures for maintenance and repairs are charged to operations as incurred. Significant expenditures that improve or extend the life of the asset are capitalized. Construction in Progress and Land includes undeveloped land as well as construction in progress related to shopping center developments and expansions. The Company capitalized certain direct costs (salaries and related personnel) and incremental internal construction costs of $3.8 million, $5.7 million and $7.4 million in 2019, 2018 and 2017, respectively.
Purchase Price Accounting	Purchase Price Accounting The Company’s acquisitions were accounted for as asset acquisitions, and the Company capitalized the acquisition costs incurred. Upon acquisition of properties, the Company estimates the fair value of acquired tangible assets, consisting of land, building and improvements and intangibles, generally including above- and below-market leases and in-place leases. The Company allocates the purchase price to assets acquired and liabilities assumed on a gross basis based on their relative fair values at the date of acquisition. In estimating the fair value of the tangible and intangible assets acquired, the Company considers information obtained about each property as a result of its due diligence and marketing and leasing activities and uses various valuation methods, such as estimated cash flow projections using appropriate discount and capitalization rates, analysis of recent comparable sales transactions, estimates of replacement costs net of depreciation and other available market information. The fair value of the tangible assets of an acquired property considers the value of the property as if it were vacant. Above- and below-market lease values are recorded based on the present value (using a discount rate that reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease and (ii) management's estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the initial term plus the estimated term of any below-market, fixed-rate renewal options for below-market leases. The capitalized above- and below-market lease values are amortized to base rental revenue over the related lease term plus fixed-rate renewal options, as appropriate. The value of acquired in-place leases is recorded based on the estimated average number of months of lease-up multiplied by the estimated gross monthly market rental rate for each individual lease. Such amounts are amortized to expense over the remaining initial lease term.
Real Estate Impairment Assessment	Real Estate Impairment Assessment The Company reviews its individual real estate assets, including undeveloped land and construction in progress, and intangibles for potential impairment indicators whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Impairment indicators include, but are not limited to, significant decreases in projected net operating income and occupancy percentages, estimated hold periods, projected losses on potential future sales, market factors, significant changes in projected development costs or completion dates and sustainability of development projects. An asset is considered impaired when the undiscounted future cash flows are not sufficient to recover the asset’s carrying value. The determination of anticipated undiscounted cash flows is inherently subjective, requiring significant estimates made by management, and considers the most likely expected course of action at the balance sheet date based on current plans, intended holding periods and available market information. If the Company is evaluating the potential sale of an asset, the undiscounted future cash flows analysis is probability-weighted based upon management’s best estimate of the likelihood of the alternative courses of action as of the balance sheet date. If an impairment is indicated, an impairment loss is recognized based on the excess of the carrying amount of the asset over its fair value. The Company recorded aggregate impairment charges of $3.4 million, $69.3 million and $340.5 million, related to consolidated real estate investments, during the years ended December 31, 2019, 2018 and 2017, respectively (Note 14).
Disposition of Real Estate and Real Estate Investments	Disposition of Real Estate and Real Estate Investments Sales of nonfinancial assets, such as real estate, are recognized when control of the asset transfers to the buyer, which will occur when the buyer has the ability to direct the use of, or obtain substantially all of the remaining benefits from, the asset. This generally occurs when the transaction closes and consideration is exchanged for control of the asset. A discontinued operation includes only the disposal of a component of an entity and represents a strategic shift that has (or will have) a major effect on an entity’s financial results. The disposition of the Company’s individual properties did not qualify for discontinued operations presentation, and thus, the results of the properties that have been sold remain in income from continuing operations, and any associated gains or losses from the disposition are included in Gain on Disposition of Real Estate.
Real Estate Held for Sale	Real Estate Held for Sale The Company generally considers assets to be held for sale when management believes that a sale is probable within a year. This generally occurs when a sales contract is executed with no substantive contingencies and the prospective buyer has significant funds at risk. Assets that are classified as held for sale are recorded at the lower of their carrying amount or fair value, less cost to sell. The Company considered the assets associated with the spin-off to RVI in 2018 as held for sale immediately prior to the distribution and therefore recorded an impairment charge of $14.1 million on the RVI portfolio primarily reflecting an estimate of the costs to sell such assets (Note 14). The Company evaluated its property portfolio and did not identify any other properties that would meet the above-mentioned criteria for held for sale as of December 31, 2019 and 2018.
Interest and Real Estate Taxes	Interest and Real Estate Taxes Interest and real estate taxes incurred relating to the construction, expansion or redevelopment of shopping centers are capitalized and depreciated over the estimated useful life of the building. This includes interest incurred on funds invested in or advanced to unconsolidated joint ventures with qualifying development activities. The Company will cease the capitalization of these costs when construction activities are substantially completed and the property is available for occupancy by tenants. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of interest and taxes until activities are resumed. Interest paid during the years ended December 31, 2019, 2018 and 2017, aggregated $79.5 million, $148.4 million and $194.7 million, respectively, of which $1.3 million, $1.1 million and $1.9 million, respectively, was capitalized.
Investments in and Advances to Joint Ventures and Affiliate	Investments in and Advances to Joint Ventures and Affiliate To the extent that the Company’s cost basis in an unconsolidated joint venture is different from the basis reflected at the joint venture level, the basis difference is amortized over the life of the related assets and included in the Company’s share of equity in net income (loss) of the joint venture. Periodically, management assesses whether there are any indicators that the value of the Company’s investments in unconsolidated joint ventures may be impaired. An investment is impaired only if the Company’s estimate of the fair value of the investment is less than the carrying value of the investment and such difference is deemed to be other than temporary. Investment impairment charges create a basis difference between the Company’s share of accumulated equity as compared to the investment balance of the respective unconsolidated joint venture. The Company allocates the aggregate impairment charge to each of the respective properties owned by the joint venture on a relative fair value basis and amortizes this basis differential as an adjustment to the equity in net income (loss) recorded by the Company over the estimated remaining useful lives of the underlying assets. The RVI Preferred Shares are classified as Investment in and Advances to Affiliate on the Company’s consolidated balance sheets. The RVI Preferred Shares have a liquidation and dividend preference over the common stock, but do not have any substantive voting rights, with limited exceptions, or conversion rights and do not have a stated coupon. The RVI Preferred Shares are carried at cost, subject to adjustments in certain circumstances, and will be periodically evaluated for impairment. Dividend payments up to $190 million received by SITE
Preferred Equity Interests	Preferred Equity Interests At December 31, 2019, the Company had net preferred equity interests of $112.6 million recorded in Investments in and Advances to Joint Ventures (Note 3). The Company evaluates the collectability of both the principal and interest on these investments based upon an assessment of the underlying collateral value to determine whether the investment is impaired. As the underlying collateral for the investments is real estate investments, the same valuation techniques are used to value the collateral as those used to determine the fair value of real estate investments for impairment purposes as disclosed above. In addition, the Company performs an additional present value of cash flows for the underlying collateral value that is probability-weighted based upon management’s estimate of the repayment timing. The preferred equity interests are considered impaired if the Company’s estimate of the fair value of the underlying collateral is less than the carrying value of the preferred equity interests. In 2019, 2018 and 2017, based upon the results of the impairment assessment, the Company recorded an aggregate valuation allowance of $15.5 million, $11.4 million and $61.0 million, respectively, related to both of its preferred equity investments to reflect the risk that the securities are not repaid in full in advance of the Company’s redemption rights in 2021 and 2022 (Note 14). Interest income on the impaired investments is recognized on a cash basis. The Company will continue to monitor the investments and related valuation allowance, which could be increased or decreased in future periods, as appropriate.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company maintains cash deposits with major financial institutions, which from time to time may exceed federally insured limits. The Company periodically assesses the financial condition of these institutions and believes that the risk of loss is minimal.
Restricted Cash	Restricted Cash Restricted cash represents amounts on deposit with financial institutions primarily for debt service payments, real estate taxes, capital improvements and operating reserves as required pursuant to the respective loan agreement. For purposes of the Company’s consolidated statements of cash flows, changes in restricted cash are aggregated with cash and cash equivalents.
Accounts Receivable	Accounts Receivable The Company makes estimates of the collectability of its accounts receivable related to base rents, including straight-line rentals, expense reimbursements and other revenue or income. Upon adoption of Topic 842, rental income for the periods beginning on or after January 1, 2019, has been reduced for amounts the Company believes are not probable of being collected. The Company analyzes accounts receivable, tenant credit worthiness and current economic trends when evaluating the probability of collection. In addition, with respect to tenants in bankruptcy, the Company makes estimates of the expected recovery of pre-petition and post-petition claims in assessing the probability of collection of the related receivable. The time to resolve these claims may exceed one year. These estimates have a direct impact on the Company’s earnings because once the amount is not considered probable of being collected, earnings are reduced by a corresponding amount until the receivable is collected. Accounts receivable, excluding straight-line rents receivable, do not include estimated amounts not probable of being collected of $1.0 million and $3.2 million at December 31, 2019 and 2018, respectively. Accounts receivable are expected to be collected within one year. The 2019 amount relates to reserves on contract disputes. At December 31, 2019 and 2018, straight-line rents receivable, net of a provision for uncollectible amounts of $2.8 million and $2.3 million, respectively, aggregated $31.2 million and $31.1 million, respectively.
Notes Receivable	Notes Receivable Notes receivable include certain loans that are held for investment and are generally collateralized by real estate-related investments and may be subordinate to other senior loans. Loans receivable are recorded at stated principal amounts or at initial investment. The Company defers loan origination and commitment fees, net of origination costs, and amortizes them over the term of the related loan. The Company evaluates the collectability of both principal and interest on each loan based on an assessment of the underlying collateral value to determine whether it is impaired, and not by the use of internal risk ratings. A loan loss reserve is recorded when, based upon current information and events, it is probable that the Company will be unable to collect all amounts due according to the existing contractual terms. When a loan is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value of the underlying collateral. As the underlying collateral for a majority of the notes receivable is real estate-related investments, the same valuation techniques are used to value the collateral as those used to determine the fair value of real estate investments for impairment purposes. Given the small number of loans outstanding, all of the Company’s loans are evaluated individually for this purpose. Interest income on performing loans is accrued as earned. Interest income on non-performing loans is recognized on a cash basis. Recognition of interest income on an accrual basis on non-performing loans is resumed when it is probable that the Company will be able to collect amounts due according to the contractual terms.
Deferred Charges	Deferred Charges External costs and fees incurred in obtaining indebtedness are included in the Company’s consolidated balance sheets as a direct deduction from the related debt liability. Debt issuance costs related to the Company’s revolving credit facilities remain classified as an asset on the consolidated balance sheets as these costs are, at the outset, not associated with an outstanding borrowing. The aggregate costs are amortized over the terms of the related debt agreements. Such amortization is reflected in Interest Expense in the Company’s consolidated statements of operations.
Treasury Shares	Treasury Shares The Company’s share repurchases are reflected as treasury shares utilizing the cost method of accounting and are presented as a reduction to consolidated shareholders’ equity. Reissuances of the Company’s treasury shares at an amount below cost are recorded as a charge to paid-in capital due to the Company’s cumulative distributions in excess of net income.
Revenue Recognition	Revenue Recognition The Company adopted the accounting guidance for revenue from contracts with customers (“Topic 606”) on January 1, 2018, using the modified retrospective approach, and therefore, the 2017 comparative information has not been adjusted. The guidance has been applied to contracts that were not completed as of the date of initial application, January 1, 2018. Most significantly for the real estate industry, leasing transactions are not within the scope of the standard. A majority of the Company’s tenant-related revenue is recognized pursuant to lease agreements and is governed by the leasing guidance. Historically, the majority of the Company’s lease commission revenue was recognized 50% upon lease execution and 50% upon tenant rent commencement. Upon adoption of Topic 606, lease commission revenue is generally recognized in its entirety upon lease execution. Rental Income • Fixed lease payments, which include fixed payments associated with expense reimbursements from tenants for common area maintenance, taxes and insurance from tenants in shopping centers, are recognized on a straight-line basis over the non-cancelable term of the lease, which generally ranges from one month to 30 years, and include the effects of applicable rent steps and abatements. • Variable lease payments, which include percentage and overage income, recognized after a tenant’s reported sales have exceeded the applicable sales breakpoint set forth in the applicable lease. • Variable lease payments associated with expense reimbursements from tenants for common area maintenance, taxes, insurance and other property operating expenses, based upon the tenant’s lease provisions, which are recognized in the period the related expenses are incurred. • Lease termination payments, which are recognized upon the effective termination of a tenant’s lease when the Company has no further obligations under the lease. • Ancillary and other property-related rental payments, primarily composed of leasing vacant space to temporary tenants, kiosk income, and parking income, which are recognized in the period earned. Business Interruption Income The Company will record revenue for covered business interruption in the period it determines that it is probable it will be compensated and the applicable contingencies with the insurance company are resolved. This income recognition criteria will likely result in business interruption insurance recoveries being recorded in a period subsequent to the period the Company experiences lost revenue from the damaged properties. Revenues from Contracts with Customers The Company’s revenues from contracts with customers generally relate to asset and property management fees, leasing commission and development fees. These revenues are derived from the Company’s management agreements with RVI and unconsolidated joint ventures and, in the case of unconsolidated joint ventures, are recognized to the extent attributable to the unaffiliated ownership in the unconsolidated joint venture to which it relates. Termination rights under these contracts vary by contract but generally include termination for cause by either party or due to sale of the property. Asset and Property Management Fees Asset and property management services include property maintenance, tenant coordination, accounting and financial services. Asset and property management services represent a series of distinct daily services. Accordingly, the Company satisfies the performance obligation as services are rendered over time. The Company is compensated for property management services through a monthly management fee earned based on a specified percentage of the monthly rental receipts generated from the property under management. The Company is compensated for asset management services through a fee that is billed to the customer monthly and recognized as revenue monthly as the services are rendered, based on a percentage of aggregate asset value or capital contributions for assets under management at the end of the quarter. The asset management fee under the RVI external management agreement is paid monthly based on the initial aggregate appraised value of the RVI properties. RVI property management fees are paid monthly based on the average gross revenue collected during the three months immediately preceding the most recent December 31 or June 30. Property Leasing The Company provides strategic advice and execution to third parties, including RVI and certain joint ventures, in connection with the leasing of retail space. The Company is compensated for services in the form of a commission. The commission is paid upon the occurrence of certain contractual events that may be contingent. For example, a portion of the commission may be paid upon execution of the lease by the tenant, with the remaining paid upon occurrence of another future contingent event (e.g., payment of first month’s rent or tenant move-in). The Company typically satisfies its performance obligation at a point in time when control is transferred, generally, at the time of the first contractual event where there is a present right to payment. The Company looks to history, experience with a customer and deal-specific considerations to support its judgment that the second contingency will be met. Therefore, the Company typically accelerates the recognition of revenue associated with the second contingent event (if any) to the point in time when control of its service is transferred. Development Services Development services consist of construction management oversight services such as hiring general contractors, reviewing plans and specifications, performing inspections, reviewing documentation and accounting services. These services represent a series of distinct services and are recognized over time as services are rendered. The Company is compensated monthly for services based on percentage of aggregate amount spent on the construction during the month. Disposition Fees The Company receives disposition fees equal to 1% of the gross sales price of each RVI asset sold. The Company is compensated at the time of the closing of the sale transaction. Contract Assets Contract assets represent assets for revenue that have been recognized in advance of billing the customer and for which the right to bill is contingent upon something other than the passage of time. This is common for contingent portions of commissions. The portion of payments retained by the customer until the second contingent event is not considered a significant financing component because the right to payment is expected to become unconditional within one year or less. Contract assets are transferred to receivables when the right to payment becomes unconditional.
General and Administrative Expenses	General and Administrative Expenses General and administrative expenses include certain internal leasing and legal salaries and related expenses associated with the re-leasing of existing space, which are charged to operations as incurred.
Equity-Based Plans	Equity-Based Plans Compensation cost relating to stock-based payment transactions classified as equity is recognized in the financial statements based upon the grant date fair value. The forfeiture rate is based on actual expectations. Under the anti-dilution provisions of the Company’s equity incentive plan, stock-based compensation was adjusted as of the spin-off of RVI, effective July 1, 2018, as determined by the Company’s compensation committee. The adjustments were made so as to retain the same intrinsic value immediately after the spin-off to that the award had immediately prior to the spin-off. Certain awards are dual-indexed to both the Company and RVI results and accounted for as liability awards and marked to fair value on a quarterly basis. Stock-based compensation cost recognized by the Company was $9.2 million, $7.7 million and $11.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. These amounts include $1.4 million and $5.5 million of expense related to the accelerated vesting of awards due to employee separations in 2018 and 2017, respectively. This cost is included in General and Administrative Expenses in the Company’s consolidated statements of operations.
Income Taxes	Income Taxes The Company has made an election to qualify, and believes it is operating so as to qualify, as a real estate investment trust (“REIT”) for federal income tax purposes. Accordingly, the Company generally will not be subject to federal income tax, provided that it makes distributions to its shareholders equal to at least the amount of its REIT taxable income as defined under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and continues to satisfy certain other requirements. In connection with the REIT Modernization Act, the Company is permitted to participate in certain activities and still maintain its qualification as a REIT, so long as these activities are conducted in entities that elect to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal and state income taxes on the income from these activities. The Tax Cuts and Jobs Act was enacted on December 22, 2017. It included numerous law changes for tax years beginning after December 31, 2017, some of which are applicable to REITs. The changes did not have a material impact on the Company’s financial statements. In the normal course of business, the Company or one or more of its subsidiaries is subject to examination by federal, state and local tax jurisdictions as well as certain jurisdictions outside the United States, in which it operates, where applicable. The Company expects to recognize interest and penalties related to uncertain tax positions, if any, as income tax expense. For the three years ended December 31, 2019, the Company recognized no material adjustments regarding its tax accounting treatment for uncertain tax provisions. As of December 31, 2019, the tax years that remain subject to examination by the major tax jurisdictions under applicable statutes of limitations are generally the year 2016 and forward.
Deferred Tax Assets	Deferred Tax Assets The Company accounts for income taxes related to its taxable REIT subsidiary (“TRS”) under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in the income statement in the period that includes the enactment date. The Company records net deferred tax assets to the extent it believes it is more likely than not that these assets will be realized. A valuation allowance is recorded against the deferred tax assets when the Company determines that an uncertainty exists regarding their realization, which would increase the provision for income taxes. In making such determination, the Company considers all available positive and negative evidence, including forecasts of future taxable income, the reversal of other existing temporary differences, available net operating loss carryforwards, tax planning strategies and recent results of operations. Several of these considerations require assumptions and significant judgment about the forecasts of future taxable income and must be consistent with the plans and estimates that the Company is utilizing to manage its business. As a result, to the extent facts and circumstances change, an assessment of the need for a valuation allowance should be made.
Segment	Segments The Company has two reportable operating segments: shopping centers and loan investments. The Company’s chief operating decision maker may review operational and financial data on a property basis and does not differentiate properties on a geographical basis for purposes of allocating resources or capital. The Company evaluates individual property performance primarily based on net operating income before depreciation, amortization and certain nonrecurring items. Each consolidated shopping center is considered a separate operating segment; however, each shopping center, on a stand-alone basis, represents less than 10% of revenues, profit or loss, and assets of the combined reported operating segment and meets the majority of the aggregations criteria under the applicable standard.
Fair Value Hierarchy	Fair Value Hierarchy The standard Fair Value Measurements • Level 1 Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 Quoted prices for identical assets and liabilities in markets that are inactive, quoted prices for similar assets and liabilities in active markets or financial instruments for which significant inputs are observable, either directly or indirectly, such as interest rates and yield curves that are observable at commonly quoted intervals and • Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined 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.
New Accounting Standard Adopted and to be Adopted	New Accounting Standard Adopted Accounting for Leases The Company adopted Topic 842, as of January 1, 2019, using the modified retrospective approach by applying the transition provisions at the beginning of the period of adoption. T • The package of practical expedients which, among other things, allowed the Company to carry forward the historical lease classification; • Land easements, allowing the Company to carry forward the accounting treatment for land easements on existing agreements and • To not separate lease and non-lease components for all leases and recording the combined component based on its predominant characteristics as rental income or expense. The Company did not adopt the practical expedient to use hindsight in determining the lease term. The Company made the following accounting policy elections in connection with the adoption: • As a lessee — the short-term lease exception for the Company’s office leases; • As a lessor — to include operating lease liabilities in the asset group and include the associated operating lease payments in the undiscounted cash flows when considering recoverability of a long-lived asset group and • As a lessor — to exclude from lease payments taxes assessed by a governmental authority that are both imposed on and concurrent with lease revenue-producing activity and collected by the lessor from the lessee (i.e., sales tax). Upon adoption of the standard, the Company’s consolidated financial statements were impacted as follows: • The Company had ground lease agreements in which the Company is the lessee for land beneath all or a portion of the buildings at three shopping centers and three additional leases where the Company is the lessee (Note 7), where the Company has recorded its rights and obligations under these leases as a right-of-use (“ROU”) asset and lease liability, which is included in Other Assets and Accounts Payable and Other Liabilities, respectively, in the consolidated balance sheet. Previously, the Company accounted for these arrangements as operating leases. These leases will continue to be classified as operating leases due to the election of the package practical expedients. The Company recorded ROU assets and lease liabilities of approximately $22.0 million and $40.3 million, respectively, as of January 1, 2019. The difference between the ROU asset and lease liability was primarily due to the straight-line rent balance that existed as of the date of the application of the standard. • Previously, the Company included real estate taxes paid by a lessee directly to a third party in recoveries from tenants and real estate tax expense, on a gross basis. Upon adoption of the standard, the Company no longer records these amounts in revenue or expense as the standard precludes the Company from recording payments made to a third party directly by the lessee. In addition, on January 1, 2019, the Company reversed $1.7 million of real estate taxes paid by certain major tenants previously reflected in Accounts Receivable and Accounts Payable and Other Liabilities on the Company’s consolidated balance sheet as of December 31, 2018. • Upon adoption of the practical expedient with regard to not separating lease and non-lease components, where applicable, the Company has prospectively recorded, on a straight-line basis, lease payments associated with fixed expense reimbursements. • The adoption of this standard did not materially impact the Company’s consolidated net income or consolidated cash flows. The adoption of the new standard also resulted in various presentation changes in the Company’s consolidated statements of operations. The Company aggregated the following components of contractual lease payments into one line item referred to as Rental Income which includes minimum rents, percentage and overage rents, recoveries from tenants, ancillary income and lease termination fees.
