Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Nature of Business DDR Corp. and its related consolidated real estate subsidiaries (collectively, the “Company” or “DDR”) 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 DDR include DDR Corp. and its wholly-owned subsidiaries and consolidated joint ventures. The Company’s tenant base primarily includes national and regional retail chains and local retailers. Consequently, the Company’s credit risk is concentrated in the retail industry. On July 1, 2018, the Company completed a spin-off of 48 shopping centers, representing $2.7 billion of gross book asset value and $1.27 billion of mortgage debt, as of June 30, 2018, composed of 36 continental U.S. assets and all 12 of DDR’s shopping centers in Puerto Rico, into a separate, publicly-traded real estate investment trust (“REIT”), Retail Value Inc. (“RVI”). DDR has retained a preferred stock investment in RVI of $190 million and expects to continue to manage the RVI assets pursuant to management agreements. At June 30, 2018, RVI was a wholly-owned subsidiary of DDR Corp. 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. Unaudited Interim Financial Statements These financial statements have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three and six months ended June 30, 2018 and 2017, are not necessarily indicative of the results that may be expected for the full year. These condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 . 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 $230.3 million and $284.1 million as of June 30, 2018 and December 31, 2017, respectively. 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): Six Months Ended June 30, 2018 2017 Accounts payable related to construction in progress $ 16.7 $ 15.7 Receivable and reduction of real estate assets, net - related to hurricane 7.8 — Assumption of building due to ground lease termination 2.2 — Dividends declared 78.7 76.7 Conversion of Operating Partnership Units 0.9 — Common Shares The Company declared common share dividends of $0.38 per share for each of the three months ended June 30, 2018 and 2017 and $0.76 per share for the six months ended June 30, 2018 and 2017. Effect of Reverse Stock Split on Presentation In May 2018, the Board of Directors of the Company, pursuant to authority granted by the shareholders, approved a one-for-two reverse stock split of the Company’s common shares as of May 18, 2018. All share and per share data included in these unaudited condensed consolidated financial statements give retroactive effect to the reverse stock split for all periods presented. New Accounting Standards Adopted Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers Real Estate Sales In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“Topic 610”) for gains and losses from the sale and/or transfer of real estate property. Topic 610 eliminates guidance specific to real estate sales in ASC 360-20. As such, sales and partial sales of real estate assets will now be subject to the same derecognition model as all other nonfinancial assets. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The effective date of this guidance coincides with revenue recognition guidance discussed in Note 2. On January 1, 2018, the Company adopted Topic 610 using the modified retrospective approach for contracts that are not completed as of the date of initial application. The Company has determined that the adoption of this standard did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards to Be Adopted Accounting for Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Leases The Company is in the process of evaluating the impact that the adoption of ASU No. 2016-02 will have on its consolidated financial statements and disclosures. The Company has currently identified several areas within its accounting policies it believes could be impacted by the new standard, including where the Company is a lessor under its tenant lease agreements and a lessee under its ground leases. The Company may have a change in presentation on its consolidated statements of operations with regards to Recoveries from Tenants, which includes reimbursements from tenants for certain operating expenses, real estate taxes and insurance. The Company also has certain lease arrangements with its tenants for space at its shopping centers in which the contractual amounts due under the lease by the lessee are not allocated between the rental and expense reimbursement components (“Gross Leases”). The aggregate revenue earned under Gross Leases is presented as Minimum Rents in the consolidated statements of operations. In July 2018, the FASB approved targeted improvements to the Leases standard that provides lessors with a practical expedient by class of underlying asset, to avoid separating the non-lease components from the lease component of certain contracts. Such practical expedient is limited to circumstances in which (i) the timing and pattern of transfer are the same for the non-lease component and the related lease component and (ii) the stand alone lease component would be classified as an operating lease if accounted for separately. The Company will elect the practical expedient which would allow the Company the ability to account for the combined component based on its predominate characteristics if the underlying asset meets the two criteria defined above. In addition, the Company has ground lease agreements in which the Company is the lessee for land beneath all or a portion of the buildings at three shopping centers. Currently, the Company accounts for these arrangements as operating leases. Under the new standard, the Company will record its rights and obligations under these leases as a right of use asset and lease liability on its consolidated balance sheets. The Company is currently in the process of evaluating the inputs required to calculate the amount that will be recorded on its balance sheet for each ground lease. Lastly, this standard impacts the lessor’s ability to capitalize initial direct costs related to the leasing of vacant space. However, the Company does not believe this change regarding capitalization will have a material impact on its consolidated financial statements. Accounting for Credit Losses In June 2016, the FASB issued an amendment on measurement of credit losses on financial assets held by a reporting entity at each reporting date. The guidance requires the use of a new current expected credit loss ("CECL") model in estimating allowances for doubtful accounts with respect to accounts receivable, straight-line rents receivable and notes receivable. The CECL model requires that the Company estimate its lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the estimated net amounts expected to be collected. This guidance is effective for fiscal years, and for interim reporting periods within those fiscal years, beginning after December 15, 2019. The Company is in the process of evaluating the impact of this guidance.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	2 . Revenue Recognition The Company has adopted the new accounting guidance for revenue from contracts with customers (“Topic 606”) on January 1, 2018 using the modified retrospective approach and therefore, the comparative information has not been adjusted. The guidance has been applied to contracts that are not completed as of the date of initial application. Most significantly for the real estate industry, leasing transactions are not within the scope of the new standard. A majority of the Company’s tenant-related revenue is recognized pursuant to lease agreements and will be governed by the leasing guidance discussed in Note 1. Historically, the majority of the Company’s lease commission revenue has been recognized 50% upon lease execution and 50% upon tenant rent commencement. Upon adoption of Topic 606, lease commission revenue will generally be recognized in its entirety upon lease execution. The impact of adopting Topic 606 on the Company’s consolidated financial statements with respect to the change in revenue recognition as related to lease commissions revenue at January 1, 2018 and for the three and six months ended June 30, 2018 was not material. The following is disclosure of the Company’s revenue recognition policies: Rental Revenue Minimum rents from tenants in shopping centers generally range from one month to 30 years and are recognized on a straight-line basis over the noncancelable term of the lease, which include the effects of applicable rent steps and abatements. Percentage and overage rents are recognized after a tenant’s reported sales have exceeded the applicable sales breakpoint set forth in the applicable lease. Recoveries from tenants Revenues associated with expense reimbursements from tenants for common area maintenance, taxes, insurance and other property operating expenses, based upon the tenant’s lease provisions, are recognized in the period the related expenses are incurred. Lease Termination Fees Lease termination fees are recognized upon the effective termination of a tenant’s lease when the Company has no further obligations under the lease. Ancillary income and other property income Ancillary and other property-related income, primarily composed of leasing vacant space to temporary tenants, kiosk income, parking and theatre income, is 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. 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. Disposition of Real Estate Sales of nonfinancial assets, such as real estate, are to be 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. 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 unconsolidated joint ventures and is recognized to the extent attributable to the unaffiliated ownership in the unconsolidated joint venture to which it relates. These contracts are generally five years in duration with ongoing one-year extension options by the Company. 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 quarterly in arrears and recognized as revenue monthly as the services are rendered, based on a percentage of aggregate capital contributions for assets under management at the end of the quarter. Property Leasing The Company provides strategic advice and execution to its unconsolidated 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 which 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 judgement 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 specification, 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. Contract Assets Contract assets represent assets for revenue that has 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. Revenue from contracts with customers is included in Fee and Other Income on the consolidated statement of operations and was composed of the following (in thousands): Three Months Six Months Ended June 30, Ended June 30, 2018 2017 2018 2017 Revenue from contracts with customers: Asset and property management fees $ 4,886 $ 6,017 $ 10,482 $ 12,190 Leasing commissions 1,312 1,461 2,934 3,328 Development fees 303 450 628 1,034 Total revenue from contracts with customers 6,501 7,928 14,044 16,552 Other fee income: Ancillary and other property income 4,817 4,660 9,160 8,992 Lease termination fees 2,695 630 3,216 808 Other 714 890 1,326 1,773 Total fee and other income $ 14,727 $ 14,108 $ 27,746 $ 28,125 The aggregate amount of receivables from contracts with customers was $1.7 million and $1.9 million as of June 30, 2018 and December 31, 2017, respectively. Contract assets are included in Other Assets, net on the consolidated balance sheets. The significant changes in the contract asset balances during the six months ended June 30, 2018 are as follows (in thousands): Balance as of January 1, 2018 $ 1,371 Contract assets recognized 1,191 Contract assets billed (1,180 ) Balance as of June 30, 2018 $ 1,382 All revenue from contracts with customers meets the exemption criteria for variable consideration directly allocable to wholly unsatisfied performance obligations or unsatisfied promise within a series and, therefore, the Company does not disclose the value of transaction price allocated to unsatisfied performance obligations. There is no fixed consideration included in the transaction price for any of these revenues.

Service fees and income earned by the Company through management, leasing and development activities performed related to all of the Company’s unconsolidated joint ventures and interest income on its preferred interests in the BRE DDR Retail Holdings joint ventures are as follows (in millions): Three Months Six Months Ended June 30, Ended June 30, 2018 2017 2018 2017 Revenue from contracts with customers: Asset and property management fees $ 4.9 $ 6.0 $ 10.5 $ 12.2 Development fees and leasing commissions 1.6 1.9 3.5 4.4 Total revenue from contracts with customers 6.5 7.9 14.0 16.6 Other: Interest income 4.8 6.3 9.8 13.8 Other 0.7 0.7 1.2 1.4 Total fee and other income $ 12.0 $ 14.9 $ 25.0 $ 31.8 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. BRE DDR Retail Holdings 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 and are summarized as follows (in millions, except properties owned): Common Equity Preferred Investment (Principal) Properties Owned Formation Initial Initial June 30, 2018 Net of Reserve Inception June 30, 2018 BRE DDR III Oct 2014 $ 19.6 $ 300.0 $ 219.9 $ 171.2 70 28 BRE DDR IV Dec 2015 12.9 82.6 66.7 52.0 6 5 $ 382.6 $ 286.6 $ 223.2 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 DDR 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 reassessed the aggregate valuation allowance at June 30, 2018, with respect to its preferred investments in BRE DDR III and BRE DDR IV. Based upon actual timing and values of recent property sales, as well as current market assumptions, the Company adjusted the aggregate valuation allowance by a reduction of $1.6 million and an increase of $2.3 million for the three- and six-month periods ending June 30, 2018, respectively, resulting in a net valuation allowance of $63.4 million. The valuation allowance is recorded as Reserve of Preferred Equity Interests on the Company’s consolidated statements of operations. The Company will continue to monitor the investments and related valuation allowance which could be increased or decreased in future periods, as appropriate. 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 distribution or “PIK.” 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. Disposition of Shopping Centers From January 1, 2018 to June 30, 2018, the DDRM Properties joint venture sold 12 assets for $191.8 million, the BRE DDR III joint venture sold nine assets for $193.9 million and the BRE DDR IV joint venture sold one asset for $40.0 million. The Company’s pro rata share of the aggregate gain from these sales was $9.3 million.

Revolving Credit Facilities	5. Revolving Credit Facilities The following table discloses certain information regarding the Company’s Revolving Credit Facilities (as defined below) (in millions): Carrying Amount at June 30, 2018 Weighted-Average Interest Rate (A) at June 30, 2018 Maturity Date Unsecured Credit Facility $ 45.0 3.3% September 2021 PNC Facility — N/A September 2021 (A) Interest rate on variable-rate debt was calculated using the base rate and spreads in effect at June 30, 2018. The Company maintains an unsecured revolving credit facility with a syndicate of financial institutions, arranged by J.P. Morgan Chase Bank, N.A., Wells Fargo Securities, LLC, Citizens Bank, N.A., RBC Capital Markets and U.S. Bank National Association (the “Unsecured Credit Facility”). The Unsecured Credit Facility provides for borrowings up to $950 million if certain financial covenants are maintained, two six-month options to extend the maturity to September 2022 upon the Company’s request (subject to satisfaction of certain conditions) 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. 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 25 basis points on the entire facility at June 30, 2018. The Company also maintains an unsecured revolving credit facility with PNC Bank, National Association (the “PNC Facility” and, together with the Unsecured Credit Facility, the “Revolving Credit Facilities”). The PNC Facility terms are substantially consistent with those contained in the Unsecured Credit Facility. In July 2018, the Company permanently reduced the borrowing capacity under the PNC Facility to $20 million (Note 13). 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 (1.2% at June 30, 2018) or the Alternative Base Rate, plus a specified spread (0.20% at June 30, 2018), as defined in the respective facility. The specified spreads vary depending on the Company’s long-term senior unsecured debt rating from Moody’s Investors Service, Inc. and S&P Global Ratings 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 June 30, 2018.

Indebtedness	6 . Indebtedness New Secured Financing On February 14, 2018, certain wholly-owned subsidiaries of RVI (collectively, the “Borrowers”), entered into a Loan Agreement (the “Loan Agreement”) which provides for a secured loan facility with an initial aggregate principal amount of $1.35 billion (the “Loan Facility”) in connection with the spin-off of RVI. The Borrowers’ obligations to pay principal, interest and other amounts under the Loan Facility are evidenced by certain promissory notes executed by the Borrowers (collectively, the “Notes”) which are secured by, among other things: (i) certain mortgages encumbering the Borrowers’ respective continental U.S. properties (a total of 36 properties); (ii) a pledge of the direct equity interest in the RVI subsidiaries that own the 12 Puerto Rico properties and a pledge of rents and other cash flows, insurance proceeds and condemnation awards in connection with the 12 Puerto Rico properties and (iii) a pledge of certain reserves and accounts of the Borrowers. Subsequent to closing, the originating lenders placed the Notes into a securitization trust which issued and sold mortgage-backed securities to investors. The Loan Facility will mature on February 9, 2021, subject to two successive one-year extensions at Borrowers’ option conditioned upon, among other items, (i) an event of default shall not be continuing, (ii) in the case of the first one-year extension option, evidence that the debt yield (as defined and calculated in accordance with the Loan Agreement, but which is the ratio of net operating income of the continental U.S. properties to the outstanding principal amount of the Loan Facility) (the “Debt Yield”) equals or exceeds 11% and the ratio of the outstanding principal amount of the Notes to the value of the continental U.S. properties (based on appraisal values determined at the time of the initial closing) (the “Loan-to-Value Ratio”) is less than or equal to 50%, and (iii) in the case of the second one-year extension option, evidence that the Debt Yield equals or exceeds 12% and the Loan-to-Value Ratio is less than or equal to 45%. The initial weighted-average interest rate applicable to the Notes is equal to one-month LIBOR plus a spread of 3.15% per annum, provided that such spread is subject to an increase of 0.25% per annum in connection with any exercise of the first extension option and an additional increase of 0.25% per annum in connection with any exercise of the second extension option. Borrowers are required to maintain an interest rate cap with respect to the principal amount of the Notes having (i) during the initial term of the Loan Facility, a LIBOR strike rate equal to 3.0% and (ii) with respect to any extension period, a LIBOR strike rate that would result in a debt service coverage ratio of 1.20x based on the continental U.S. properties. Mortgage-backed securities securitized by the Notes were sold by the lenders to investors at a blended rate (prior to exercise of any extension option) of one-month LIBOR plus a spread of 2.91% per annum; the spread paid increased to 3.15% per annum based on terms included in the originating lenders’ initial financing commitment to Borrowers. Application of voluntary prepayments as described below may cause the weighted-average interest rate to increase over time. The Loan Facility is structured as an interest only loan throughout the initial three-year term and any exercised extension options. As a result, so long as no Amortization Period (as described below) or event of default exists, any property cash flows available following payment of debt service and funding of certain required reserve accounts (including reserves for payment of real estate taxes, insurance premiums, ground rents, tenant improvements and capital expenditures), will be available to the Borrowers for general corporate purposes. An Amortization Period will be deemed to commence in the event the Borrowers fail to achieve a Debt Yield of 10.8%, 11.9%, 14.1% and 19.2% as of March 31, 2019, September 30, 2019, March 31, 2020 and September 30, 2020, respectively. In the event an Amortization Period occurs, any property cash flows available following payment of debt service and the funding of certain reserve accounts (including the reserve accounts referenced above and additional reserves established for payment of approved operating expenses, DDR management fees, certain public company costs, certain taxes and the minimum cash portion of required REIT distributions) shall be applied to the repayment of the Notes. During an Amortization Period, cash flow from the Borrowers’ operations will only be made available to RVI to pay required REIT distributions in an amount equal to the minimum portion of required REIT distributions allowed by law to be paid in cash (currently 20%), with the remainder of required REIT distributions during an Amortization Period likely to be paid by RVI in shares of its common stock. Subject to certain conditions described in the Loan Agreement, the Borrowers may prepay principal amounts outstanding under the Loan Facility in whole or in part by providing (i) advance notice of prepayment to the lenders and (ii) remitting the prepayment premium described in the Loan Agreement. No prepayment premium is required with respect to any prepayments made after March 9, 2019. Additionally, no prepayment premium will apply to prepayments made in connection with permitted property sales. Each continental U.S. property has a portion of the original principal amount of the Loan Facility allocated to it (the “Allocated Loan Amount”). The amount of proceeds from the sale of an individual continental U.S. property required to be applied towards prepayment of the Notes (i.e., the property’s “release price”) will depend upon the Debt Yield at the time of the sale as follows: • if the Debt Yield is less than or equal to 12.0%, the release price is the greater of (i) 100% of the property’s net sale proceeds and (ii) 110% of its Allocated Loan Amount; • if the Debt Yield is greater than 12.0% but less than or equal to 15.0%, the release price is the greater of (i) 90% of the property’s net sale proceeds and (ii) 105% of its Allocated Loan Amount and • if the Debt Yield is greater than 15.0%, the release price is the greater of (i) 80% of the property’s net sale proceeds and (ii) 100% of its Allocated Loan Amount. Once the aggregate principal amount of the Notes is less than $270.0 million, 100% of net proceeds from the sales of continental U.S. properties must be applied towards prepayment of the Notes. Properties in Puerto Rico do not have Allocated Loan Amounts or minimum release prices; all proceeds from sales of Puerto Rico properties are required to be used to prepay the Notes, except that the Borrowers can obtain a release of all of the Puerto Rico properties for a minimum release price of $350.0 million. Voluntary prepayments made by the Borrowers (including prepayments made with proceeds from asset sales) up to $337.5 million in the aggregate will be applied ratably to the senior and junior tranches of the Notes. All other prepayments (including prepayments made with property cash flows following commencement of any Amortization Period) will be applied to tranches of Notes (i) absent an event of default, in descending order of seniority (i.e., such prepayments will first be applied to the most senior tranches of Notes) and (ii) following any event of default, in such order as the loan servicer determines in its sole discretion. As a result, it is expected that the weighted average interest rate of the Notes will increase during the term of the Loan Facility. In the event of a default, the contract rate of interest on the Notes will increase to the lesser of (i) the maximum rate allowed by law, or (ii) the greater of (A) 4% above the interest rate otherwise applicable and (B) the Prime Rate (as defined in the Loan Agreement) plus 1.0%. The Notes contain other terms and provisions that are customary for instruments of this nature. In addition, a certain Environmental Indemnity Agreement and a certain Guaranty Agreement was executed in favor of the lenders under which RVI, a wholly-owned subsidiary of DDR at June 30, 2018, agreed to indemnify the lenders for certain environmental risks and guaranty the Borrowers’ obligations under the exceptions to the non-recourse provisions in the Loan Agreement. The Loan Agreement includes representations, warranties, affirmative and restrictive covenants and other provisions customary for agreements of this nature. The Loan Agreement also includes customary events of default, including, among others, principal and interest payment defaults, and breaches of affirmative or negative covenants; the Loan Agreement does not contain any financial maintenance covenants. Upon the occurrence of an event of default, the lenders may avail themselves of various customary remedies under the Loan Agreement and other agreements executed in connection therewith or applicable law, including accelerating the Loan Facility and realizing on the real property collateral or pledged collateral. At June 30, 2018, the mortgage balance outstanding was $1.27 billion. This mortgage was assumed by RVI in connection with the spin-off of RVI on July 1, 2018 (Note 13). Debt Repayments In the first quarter of 2018, in connection with the $1.35 billion mortgage loan and asset sales, the Company repaid $900.0 million aggregate principal amount of senior unsecured notes with maturity dates ranging from July 2018 to February 2025 through a tender offer, $452.5 million of mortgage debt and $200.0 million of an unsecured term loan. In connection with the redemption of the senior unsecured notes, the Company paid make-whole amounts totaling $28.4 million. These make whole amounts are included in Other Income (Expense), net in the Company’s consolidated statements of operations. Scheduled Principal Repayments The scheduled principal payments of the Revolving Credit Facilities (Note 5) and unsecured and secured indebtedness, excluding extension options, as of June 30, 2018, are as follows (in thousands): Year Amount 2018 $ 24,487 2019 97,241 2020 41,684 2021 (A) 1,332,140 2022 481,068 Thereafter 1,653,894 3,630,514 Unamortized fair market value of assumed debt 2,042 Net unamortized debt issuance costs (42,807 ) Total indebtedness $ 3,589,749 (A) Includes $1.27 billion RVI mortgage, which was assumed by RVI in connection with the spin-off of RVI on July 1, 2018 (Note 13).

Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	7 . Financial Instruments and Fair Value Measurements The following methods and assumptions were used by the Company in estimating fair value disclosures of financial instruments: Notes Receivable and Advances to Affiliates The fair value is estimated using a discounted cash flow analysis in which the Company uses unobservable inputs such as market interest rates determined by the loan to value and market capitalization rates related to the underlying collateral at which management believes similar loans would be made and classified as Level 3 in the fair value hierarchy. The fair value of these notes was approximately $249.1 million and $299.0 million at June 30, 2018 and December 31, 2017, respectively, as compared to the carrying amounts of $248.2 million and $297.9 million, respectively. 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 than estimated fair values are summarized as follows (in thousands): June 30, 2018 December 31, 2017 Carrying Amount Fair Value Carrying Amount Fair Value Senior Notes $ 1,918,263 $ 1,916,271 $ 2,810,100 $ 2,884,272 Revolving Credit Facilities and term loans 243,461 245,202 398,130 400,119 Mortgage Indebtedness 1,428,025 1,458,654 641,082 653,185 $ 3,589,749 $ 3,620,127 $ 3,849,312 $ 3,937,576 Interest Rate Cap In March 2018, the Company entered into a $1.35 billion interest rate cap, in connection with entering into the RVI mortgage (Note 6). At June 30, 2018, the notional amount of the interest rate cap was $1.27 billion. The fair value of the interest rate cap was $4.8 million at June 30, 2018, and was included in Other Assets. Changes in fair value are marked to market to earnings in Other Income (Expense). For the three and six months ended June 30, 2018, the Company recorded income of $0.4 million and $0.2 million, respectively. The Company’s objective in using interest rate derivatives is to manage its exposure to interest rate movements. To accomplish this objective, the Company generally uses interest rate instruments as part of its interest rate risk management strategy. The Company is exposed to credit risk in the event of non-performance by the counterparties. The Company believes it mitigates its credit risk by entering into these arrangements with major financial institutions. The Company continually monitors and actively manages interest costs on its variable-rate debt portfolio and may enter into additional interest rate positions or other derivative interest rate instruments based on market conditions. The Company has not entered, and does not plan to enter, into any derivative financial instruments for trading or speculative purposes.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	8 . Commitments and Contingencies Hurricane Loss In 2017, Hurricane Maria made landfall in Puerto Rico. At June 30, 2018, the Company owned 12 assets in Puerto Rico, aggregating 4.4 million square feet of Company-owned GLA. One of the 12 assets (Plaza Palma Real, consisting of approximately 0.4 million of Company-owned GLA) was severely damaged and is currently not operational, except for one anchor tenant and a few other tenants representing a minimal amount of Company-owned GLA. The other 11 assets sustained varying degrees of damage, consisting primarily of roof and HVAC system damage and water intrusion. With respect to the Company’s anchor spaces comprising greater than 25,000 square feet of GLA in Puerto Rico, 27, or 82% of such tenants, were open as of July 25, 2018, including all seven Walmart stores, a Sam's Club, both Home Depot stores, all three Sears/Kmart stores and all five grocery stores (including Pueblo, Econo and Selectos Supermarket). Although some tenant spaces remain untenantable, as of July 25, 2018, 86% of leased GLA was open for business, excluding Plaza Palma Real (or 82% including Plaza Palma Real). The Company has engaged various consultants to assist with the damage scoping assessment. The Company continues to work with its consultants to finalize the scope and schedule of work to be performed. Restoration work is underway at all of the shopping centers, including Plaza Palma Real. The Company anticipates that repairs will be substantially complete at all 12 properties by the third quarter of 2019. The timing and schedule of additional repair work to be completed are highly dependent upon any changes in the scope of work as well as the availability of building materials, supplies and skilled labor. The Company maintains insurance on its assets in Puerto Rico with policy limits of approximately $330 million for both property damage and business interruption. The Company's insurance policies are subject to various terms and conditions, including a combined property damage and business interruption deductible of approximately $6.0 million. The Company expects that its insurance for property damage and business interruption claims will include the costs to clean up, repair and rebuild the properties, as well as lost revenue. Certain continental-U.S.-based anchor tenants maintain their own property insurance on their Company-owned premises and are expected to make the required repairs to their stores. The Company is unable to estimate the impact of potential increased costs associated with resource constraints in Puerto Rico relating to building materials, supplies and labor. The Company believes it maintains adequate insurance coverage on each of its properties and is working closely with the insurance carriers to obtain the maximum amount of insurance recovery provided under the policies. However, the Company can give no assurances as to the amounts of such claims, timing of payments and resolution of the claims. As of June 30, 2018, the estimated net book value of the property damage written off for damage to the Company’s Puerto Rico assets was $78.8 million. However, the Company continues to assess the impact of the hurricane on its properties, and the final net book value write-offs could vary significantly from this estimate. Any changes to this estimate will be recorded in the periods in which they are determined. The Company’s Property Insurance Receivable was $49.2 million at June 30, 2018, which represents estimated insurance recoveries related to the net book value of the property damage written off as well as other expenses, as the Company believes it is probable that the insurance recovery, net of the deductible, will exceed the net book value of the damaged property. The outstanding receivable is recorded as Property Insurance Receivable on the Company’s consolidated balance sheets as of June 30, 2018. The Company received an additional $20.2 million toward the property damage portion of its insurance claim in the second quarter of 2018. The Company’s business interruption insurance covers lost revenue through the period of property restoration and for up to 365 days following completion of restoration. For the three and six months ended June 30, 2018, rental revenues of $2.8 million and $6.6 million, respectively, were not recorded because of lost tenant revenue attributable to Hurricane Maria that has been partially defrayed by insurance proceeds. The Company will record revenue for covered business interruption in the period it determines that it is probable it will be compensated. This income recognition criteria will likely result in business interruption insurance proceeds being recorded in a period subsequent to the period that the Company experiences lost revenue from the damaged properties. For the three and six months ended June 30, 2018, the Company received insurance proceeds of approximately $3.1 million and $5.1 million, respectively, related to business interruption claims, which is recorded on the Company’s consolidated statements of operations as Business Interruption Income.

Asset Impairment Charges [Abstract]
Impairment Charges and Reserves	10 . 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): Three Months Six Months Ended June 30, Ended June 30, 2018 2017 2018 2017 Assets marketed for sale (A) $ 18.1 $ 19.0 $ 48.5 $ 41.0 Undeveloped land — 9.1 — 9.1 (Adjustment) reserve of preferred equity interests (B) (1.6 ) — 2.3 76.0 Total impairment charges $ 16.5 $ 28.1 $ 50.8 $ 126.1 (A ) The impairments recorded during the three and six months ended June 30, 2018 primarily were triggered by indicative bids received and changes in market assumptions due to the disposition process. The impairments recorded during the three and six months ended June 30, 2017 primarily were triggered by changes in asset hold-period assumptions and/or expected future cash flows. (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. For projects under development or not at stabilization, the significant valuation 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. 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 on both financial and nonfinancial assets that were measured on a fair value basis for the six months ended June 30, 2018. The table also indicates the fair value hierarchy of the valuation techniques used by the Company to determine such fair value (in millions).

Subsequent Events	13 . Subsequent Events Retail Value Inc. On July 1, 2018, the Company completed the spin-off of RVI. At the time of the spin-off, RVI owned 48 shopping centers, comprised of 36 continental U.S. assets and all 12 of DDR’s shopping centers in Puerto Rico, representing $2.7 billion of gross book asset value and $1.27 billion of mortgage debt 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 DDR’s common shares as of the close of business on June 26, 2018, the record date. On the spin-off date, holders of DDR’s common shares received one common share of RVI for every ten shares of DDR common stock held on the record date. In connection with the spin-off, the Company retained 1,000 shares of RVI’s series A preferred stock having an aggregate preference equal to $190 million, which amount may increase by up to an additional $10 million depending on the amount of aggregate gross proceeds generated by RVI asset sales. 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 DDR will manage RVI and its properties. Pursuant to these management agreements, the Company will provide RVI with day-to-day management, subject to supervision and certain discretionary limits and authorities granted by the RVI Board, and RVI is not expected to have any employees. In general, either the Company or RVI may terminate the management agreements on December 31, 2019 or at the end of any six-month renewal period thereafter. The Company and RVI also entered into a tax matters agreement, which governs the rights and responsibilities of the parties following the spin-off with respect to various tax matters and provides for the allocation of tax-related assets, liabilities and obligations. Revolving Credit Facilities On July 2, 2018, the Company permanently reduced the availability under the PNC Facility (Note 5) from $50 million to $20 million. In addition, on July 2, 2018, DDR provided an unconditional guaranty to PNC Bank, National Association (“PNC”) with respect to any obligations of RVI outstanding from time to time under a $30 million revolving credit agreement entered into by RVI with PNC. RVI has agreed to reimburse DDR for any amounts paid to PNC pursuant to the guaranty plus interest at a contracted rate.

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2018
Accounting Policies [Abstract]
Nature Of Business	Nature of Business DDR Corp. and its related consolidated real estate subsidiaries (collectively, the “Company” or “DDR”) 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 DDR include DDR Corp. and its wholly-owned subsidiaries and consolidated joint ventures. The Company’s tenant base primarily includes national and regional retail chains and local retailers. Consequently, the Company’s credit risk is concentrated in the retail industry. On July 1, 2018, the Company completed a spin-off of 48 shopping centers, representing $2.7 billion of gross book asset value and $1.27 billion of mortgage debt, as of June 30, 2018, composed of 36 continental U.S. assets and all 12 of DDR’s shopping centers in Puerto Rico, into a separate, publicly-traded real estate investment trust (“REIT”), Retail Value Inc. (“RVI”). DDR has retained a preferred stock investment in RVI of $190 million and expects to continue to manage the RVI assets pursuant to management agreements. At June 30, 2018, RVI was a wholly-owned subsidiary of DDR Corp.
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.
Unaudited Interim Financial Statements	Unaudited Interim Financial Statements These financial statements have been prepared by the Company in accordance with GAAP for interim financial information and the applicable rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all information and footnotes required by GAAP for complete financial statements. However, in the opinion of management, the interim financial statements include all adjustments, consisting of only normal recurring adjustments, necessary for a fair statement of the results of the periods presented. The results of operations for the three and six months ended June 30, 2018 and 2017, are not necessarily indicative of the results that may be expected for the full year. These condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 .
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 $230.3 million and $284.1 million as of June 30, 2018 and December 31, 2017, respectively. 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): Six Months Ended June 30, 2018 2017 Accounts payable related to construction in progress $ 16.7 $ 15.7 Receivable and reduction of real estate assets, net - related to hurricane 7.8 — Assumption of building due to ground lease termination 2.2 — Dividends declared 78.7 76.7 Conversion of Operating Partnership Units 0.9 — Common Shares The Company declared common share dividends of $0.38 per share for each of the three months ended June 30, 2018 and 2017 and $0.76 per share for the six months ended June 30, 2018 and 2017.
Effect of Reverse Stock Split on Presentation	Effect of Reverse Stock Split on Presentation In May 2018, the Board of Directors of the Company, pursuant to authority granted by the shareholders, approved a one-for-two reverse stock split of the Company’s common shares as of May 18, 2018. All share and per share data included in these unaudited condensed consolidated financial statements give retroactive effect to the reverse stock split for all periods presented.
New Accounting Standards Adopted and to be Adopted	New Accounting Standards Adopted Revenue Recognition In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers Real Estate Sales In February 2017, the FASB issued ASU 2017-05, Other Income-Gains and Losses from Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (“Topic 610”) for gains and losses from the sale and/or transfer of real estate property. Topic 610 eliminates guidance specific to real estate sales in ASC 360-20. As such, sales and partial sales of real estate assets will now be subject to the same derecognition model as all other nonfinancial assets. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within that reporting period. The effective date of this guidance coincides with revenue recognition guidance discussed in Note 2. On January 1, 2018, the Company adopted Topic 610 using the modified retrospective approach for contracts that are not completed as of the date of initial application. The Company has determined that the adoption of this standard did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards to Be Adopted Accounting for Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). Leases The Company is in the process of evaluating the impact that the adoption of ASU No. 2016-02 will have on its consolidated financial statements and disclosures. The Company has currently identified several areas within its accounting policies it believes could be impacted by the new standard, including where the Company is a lessor under its tenant lease agreements and a lessee under its ground leases. The Company may have a change in presentation on its consolidated statements of operations with regards to Recoveries from Tenants, which includes reimbursements from tenants for certain operating expenses, real estate taxes and insurance. The Company also has certain lease arrangements with its tenants for space at its shopping centers in which the contractual amounts due under the lease by the lessee are not allocated between the rental and expense reimbursement components (“Gross Leases”). The aggregate revenue earned under Gross Leases is presented as Minimum Rents in the consolidated statements of operations. In July 2018, the FASB approved targeted improvements to the Leases standard that provides lessors with a practical expedient by class of underlying asset, to avoid separating the non-lease components from the lease component of certain contracts. Such practical expedient is limited to circumstances in which (i) the timing and pattern of transfer are the same for the non-lease component and the related lease component and (ii) the stand alone lease component would be classified as an operating lease if accounted for separately. The Company will elect the practical expedient which would allow the Company the ability to account for the combined component based on its predominate characteristics if the underlying asset meets the two criteria defined above. In addition, the Company has ground lease agreements in which the Company is the lessee for land beneath all or a portion of the buildings at three shopping centers. Currently, the Company accounts for these arrangements as operating leases. Under the new standard, the Company will record its rights and obligations under these leases as a right of use asset and lease liability on its consolidated balance sheets. The Company is currently in the process of evaluating the inputs required to calculate the amount that will be recorded on its balance sheet for each ground lease. Lastly, this standard impacts the lessor’s ability to capitalize initial direct costs related to the leasing of vacant space. However, the Company does not believe this change regarding capitalization will have a material impact on its consolidated financial statements. Accounting for Credit Losses In June 2016, the FASB issued an amendment on measurement of credit losses on financial assets held by a reporting entity at each reporting date. The guidance requires the use of a new current expected credit loss ("CECL") model in estimating allowances for doubtful accounts with respect to accounts receivable, straight-line rents receivable and notes receivable. The CECL model requires that the Company estimate its lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the estimated net amounts expected to be collected. This guidance is effective for fiscal years, and for interim reporting periods within those fiscal years, beginning after December 15, 2019. The Company is in the process of evaluating the impact of this guidance.
Revenue Recognition	The following is disclosure of the Company’s revenue recognition policies: Rental Revenue Minimum rents from tenants in shopping centers generally range from one month to 30 years and are recognized on a straight-line basis over the noncancelable term of the lease, which include the effects of applicable rent steps and abatements. Percentage and overage rents are recognized after a tenant’s reported sales have exceeded the applicable sales breakpoint set forth in the applicable lease. Recoveries from tenants Revenues associated with expense reimbursements from tenants for common area maintenance, taxes, insurance and other property operating expenses, based upon the tenant’s lease provisions, are recognized in the period the related expenses are incurred. Lease Termination Fees Lease termination fees are recognized upon the effective termination of a tenant’s lease when the Company has no further obligations under the lease. Ancillary income and other property income Ancillary and other property-related income, primarily composed of leasing vacant space to temporary tenants, kiosk income, parking and theatre income, is 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. 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. Disposition of Real Estate Sales of nonfinancial assets, such as real estate, are to be 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. 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 unconsolidated joint ventures and is recognized to the extent attributable to the unaffiliated ownership in the unconsolidated joint venture to which it relates. These contracts are generally five years in duration with ongoing one-year extension options by the Company. 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 quarterly in arrears and recognized as revenue monthly as the services are rendered, based on a percentage of aggregate capital contributions for assets under management at the end of the quarter. Property Leasing The Company provides strategic advice and execution to its unconsolidated 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 which 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 judgement 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 specification, 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. Contract Assets Contract assets represent assets for revenue that has 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.
