Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Kite Realty Group Trust (the "Parent Company"), through its majority-owned subsidiary, Kite Realty Group, L.P. (the “Operating Partnership”), owns interests in various operating subsidiaries and joint ventures engaged in the ownership and operation, acquisition, development and redevelopment of high-quality neighborhood and community shopping centers in select markets in the United States. The terms "Company," "we," "us," and "our" refer to the Parent Company and the Operating Partnership, collectively, and those entities owned or controlled by the Parent Company and/or the Operating Partnership. The Operating Partnership was formed on August 16, 2004, when the Parent Company contributed properties and the net proceeds from an initial public offering of shares of its common stock to the Operating Partnership. The Parent Company was organized in Maryland in 2004 to succeed in the development, acquisition, construction and real estate businesses of its predecessor. We believe the Company qualifies as a real estate investment trust (a “REIT”) under provisions of the Internal Revenue Code of 1986, as amended. The Parent Company is the sole general partner of the Operating Partnership, and as of September 30, 2018 owned approximately 97.6% of the common partnership interests in the Operating Partnership (“General Partner Units”). The remaining 2.4% of the common partnership interests (“Limited Partner Units” and, together with the General Partner Units, the “Common Units”) were owned by the limited partners. As the sole general partner of the Operating Partnership, the Parent Company has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership. The Parent Company and the Operating Partnership are operated as one enterprise. The management of the Parent Company consists of the same members as the management of the Operating Partnership. As the sole general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have any significant assets other than its investment in the Operating Partnership. At September 30, 2018 , we owned interests in 115 operating and redevelopment properties totaling approximately 22.4 million square feet. We also owned one development project under construction as of this date. Of the 115 properties, 112 are consolidated in these financial statements and the remaining three are accounted for under the equity method.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation, Consolidation, Investments in Joint Ventures, and Noncontrolling Interests	Basis of Presentation, Consolidation, Investments in Joint Ventures, and Noncontrolling Interests We have prepared the accompanying unaudited financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) may have been condensed or omitted pursuant to such rules and regulations, although management believes that the disclosures are adequate to make the presentation not misleading. The unaudited financial statements as of September 30, 2018 and for the three and nine months ended September 30, 2018 and 2017 include all adjustments, consisting of normal recurring adjustments, necessary in the opinion of management to present fairly the financial information set forth therein. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes thereto included in the combined Annual Report on Form 10-K of the Parent Company and the Operating Partnership for the year ended December 31, 2017 . The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reported period. Actual results could differ from these estimates. The results of operations for the interim periods are not necessarily indicative of the results that may be expected on an annual basis. Components of Investment Properties The composition of the Company’s investment properties as of September 30, 2018 and December 31, 2017 was as follows: Balance at September 30, December 31, Investment properties, at cost: Land, buildings and improvements $ 3,677,536 $ 3,873,149 Furniture, equipment and other 9,151 8,453 Land held for development 31,142 31,142 Construction in progress 34,643 45,140 $ 3,752,472 $ 3,957,884 Consolidation and Investments in Joint Ventures The accompanying financial statements are presented on a consolidated basis and include all accounts of the Parent Company, the Operating Partnership, the taxable REIT subsidiary of the Operating Partnership, subsidiaries of the Operating Partnership that are controlled and any variable interest entities (“VIEs”) in which the Operating Partnership is the primary beneficiary. In general, a VIE is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) has equity investors that do not provide sufficient financial resources for the entity to support its activities, (b) does not have equity investors with voting rights or (c) has equity investors whose votes are disproportionate from their economics and substantially all of the activities are conducted on behalf of the investor with disproportionately fewer voting rights. The Operating Partnership accounts for properties that are owned by joint ventures in accordance with the consolidation guidance. The Operating Partnership evaluates each joint venture and determines first whether to follow the VIE or the voting interest entity ("VOE") model. Once the appropriate consolidation model is identified, the Operating Partnership then evaluates whether it should consolidate the joint venture. Under the VIE model, the Operating Partnership consolidates an entity when it has (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Operating Partnership consolidates an entity when (i) it controls the entity through ownership of a majority voting interest if the entity is not a limited partnership or (ii) it controls the entity through its ability to remove the other partners or owners in the entity, at its discretion, when the entity is a limited partnership. In determining whether to consolidate a VIE with the Operating Partnership, we consider all relationships between the Operating Partnership and the applicable VIE, including development agreements, management agreements and other contractual arrangements, in determining whether we have the power to direct the activities of the VIE that most significantly affect the VIE's performance. As of September 30, 2018 , we owned investments in three consolidated joint ventures that were VIEs in which the partners did not have substantive participating rights and we were the primary beneficiary. As of this date, these VIEs had total debt of $205.7 million , which were secured by assets of the VIEs totaling $444.2 million . The Operating Partnership guarantees the debts of these VIEs. On June 29, 2018, the Company formed a joint venture involving TH Real Estate (the "TH Real Estate joint venture"). The Company sold three properties to the joint venture valued in the aggregate at $99.8 million and, after considering third party debt obtained by the venture upon formation, the Company contributed $10.0 million for a 20% noncontrolling ownership interest in the venture. The Company serves as the operating member responsible for day-to-day management of the properties and receives property management and leasing fees. Both members have substantive participating rights over major decisions that impact the economics and operations of the joint venture. The Company is accounting for the joint venture on the equity method as it has the ability to exercise influence, but not control over operating and financial policies. The Operating Partnership is considered a VIE as the limited partners do not hold kick-out rights or substantive participating rights. The Parent Company consolidates the Operating Partnership as it is the primary beneficiary in accordance with the VIE model. Income Taxes and REIT Compliance Parent Company The Parent Company, which is considered a corporation for federal income tax purposes, has been organized and intends to continue to operate in a manner that will enable it to maintain its qualification as a REIT for federal income tax purposes. As a result, it generally will not be subject to federal income tax on the earnings that it distributes to the extent it distributes its “REIT taxable income” (determined before the deduction for dividends paid and excluding net capital gains) to shareholders of the Parent Company and meets certain other requirements on a recurring basis. To the extent that it satisfies this distribution requirement, but distributes less than 100% of its taxable income, it will be subject to federal corporate income tax on its undistributed REIT taxable income. REITs are subject to a number of organizational and operational requirements. If the Parent Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate rates for a period of four years following the year in which qualification is lost. We may also be subject to certain federal, state and local taxes on our income and property and to federal income and excise taxes on our undistributed taxable income even if the Parent Company does qualify as a REIT. The Operating Partnership intends to continue to make distributions to the Parent Company in amounts sufficient to assist the Parent Company in adhering to REIT requirements and maintaining its REIT status. We have elected to treat Kite Realty Holdings, LLC as a taxable REIT subsidiary of the Operating Partnership, and we may elect to treat other subsidiaries as taxable REIT subsidiaries in the future. This election enables us to receive income and provide services that would otherwise be impermissible for a REIT. Deferred tax assets and liabilities are established for temporary differences between the financial reporting bases and the tax bases of assets and liabilities at the tax rates expected to be in effect when the temporary differences reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. Operating Partnership The allocated share of income and loss, other than the operations of our taxable REIT subsidiary, is included in the income tax returns of the Operating Partnership's partners. Accordingly, the only federal income taxes included in the accompanying consolidated financial statements are in connection with the Operating Partnership's taxable REIT subsidiary. Noncontrolling Interests We report the non-redeemable noncontrolling interests in subsidiaries as equity, and the amount of consolidated net income attributable to these noncontrolling interests is set forth separately in the consolidated financial statements. The non-redeemable noncontrolling interests in consolidated properties for the nine months ended September 30, 2018 and 2017 were as follows: 2018 2017 Noncontrolling interests balance January 1 $ 698 $ 692 Net income allocable to noncontrolling interests, — 6 Noncontrolling interests balance at September 30 $ 698 $ 698 Redeemable Noncontrolling Interests - Limited Partners Limited Partner Units are redeemable noncontrolling interests in the Operating Partnership. We classify redeemable noncontrolling interests in the Operating Partnership in the accompanying consolidated balance sheets outside of permanent equity because we may be required to pay cash to holders of Limited Partner Units upon redemption of their interests in the Operating Partnership or deliver registered shares upon their conversion. The carrying amount of the redeemable noncontrolling interests in the Operating Partnership is reflected at the greater of historical book value or redemption value with a corresponding adjustment to additional paid-in capital. At September 30, 2018 , the redemption value of the redeemable noncontrolling interests did not exceed the historical book value, and the balance was accordingly adjusted to historical book value. At December 31, 2017, the redemption value of the redeemable noncontrolling interests exceeded the historical book value, and the balance was accordingly adjusted to redemption value. We allocate net operating results of the Operating Partnership after noncontrolling interests in the consolidated properties based on the partners’ respective weighted average ownership interest. We adjust the redeemable noncontrolling interests in the Operating Partnership at the end of each reporting period to reflect their interests in the Operating Partnership or redemption value. This adjustment is reflected in our shareholders’ and Parent Company's equity. For the three and nine months ended September 30, 2018 and 2017 , the weighted average interests of the Parent Company and the limited partners in the Operating Partnership were as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Parent Company’s weighted average basic interest in 97.6 % 97.7 % 97.6 % 97.7 % Limited partners' weighted average basic interests in 2.4 % 2.3 % 2.4 % 2.3 % At September 30, 2018 , the Parent Company's interest and the limited partners' redeemable noncontrolling ownership interests in the Operating Partnership were 97.6% and 2.4% . At December 31, 2017, the Parent Company's interest and the limited partners' redeemable noncontrolling ownership interests in the Operating Partnership were 97.7% and 2.3% . Concurrent with the Parent Company’s initial public offering and related formation transactions, certain individuals received Limited Partner Units of the Operating Partnership in exchange for their interests in certain properties. The limited partners have the right to redeem Limited Partner Units for cash or, at the Parent Company's election, common shares of the Parent Company in an amount equal to the market value of an equivalent number of common shares of the Parent Company at the time of redemption. Such common shares must be registered, which is not fully in the Parent Company’s control. Therefore, the limited partners’ interest is not reflected in permanent equity. The Parent Company also has the right to redeem the Limited Partner Units directly from the limited partner in exchange for either cash in the amount specified above or a number of its common shares equal to the number of Limited Partner Units being redeemed. There were 2,048,849 and 1,974,830 Limited Partner Units outstanding as of September 30, 2018 and December 31, 2017 , respectively. The increase in Limited Partner Units outstanding from December 31, 2017 is due to non-cash compensation awards made to our executive officers in the form of Limited Partner Units. Redeemable Noncontrolling Interests - Subsidiaries Prior to the merger with Inland Diversified Real Estate Trust, Inc. ("Inland Diversified") in 2014, Inland Diversified formed joint ventures with the previous owners of certain properties and issued Class B units in three joint ventures that indirectly own those properties. The Class B units related to two of these three joint ventures remain outstanding and are accounted for as noncontrolling interests in these properties. The Class B units related to the Territory Portfolio joint venture became redeemable at the respective partner’s election in March 2017 and are discussed further below. The remaining Class B units relate to our Crossing at Killingly Commons joint venture will become redeemable at the partner's election in October 2022 and the fulfillment of certain redemption criteria. Beginning in November 2022, the Class B units can be redeemed at the election of either of our partner or us for cash or Limited Partner Units in the Operating Partnership. None of the issued Class B units have a maturity date, and none are mandatorily redeemable unless either party has elected for the units to be redeemed. We consolidate these joint ventures because we control the decision making of each of the joint ventures and our joint venture partners have limited protective rights. In February 2018, we received notice from our partners in the Territory Portfolio joint venture of their intent to exercise their right to redeem their remaining $22.0 million of Class B units for cash. The amount that will be redeemed was reclassified from Limited partners' interests in Operating Partnership and other redeemable noncontrolling interests to accounts payable and accrued expenses in the consolidated balance sheets. The Company redeemed $10 million of the interest on August 7, 2018. The Company can determine the timing of the closing for the redemption for the remaining $12 million , but it must occur before November 8, 2018. We classify the remainder of the redeemable noncontrolling interests in certain subsidiaries in the accompanying consolidated balance sheets outside of permanent equity because, under certain circumstances, we may be required to pay cash to Class B unitholders in specific subsidiaries upon redemption of their interests. The carrying amount of these redeemable noncontrolling interests is required to be reflected at the greater of initial book value or redemption value with a corresponding adjustment to additional paid-in capital. As of both September 30, 2018 and December 31, 2017, the redemption amounts of these interests did not exceed their fair value, nor did they exceed the initial book value. The redeemable noncontrolling interests in the Operating Partnership and subsidiaries for the nine months ended September 30, 2018 and 2017 were as follows: 2018 2017 Redeemable noncontrolling interests balance January 1 $ 72,104 $ 88,165 Net income allocable to redeemable noncontrolling interests 604 1,522 Distributions declared to redeemable noncontrolling interests (2,943 ) (3,099 ) Liability reclassification due to exercise of redemption option by joint venture partner (22,461 ) (8,261 ) Other, net, including adjustments to redemption value 122 (4,873 ) Total limited partners' interests in Operating Partnership and other redeemable noncontrolling interests balance at September 30 $ 47,426 $ 73,454 Limited partners' interests in Operating Partnership $ 37,356 $ 40,923 Other redeemable noncontrolling interests in certain subsidiaries 10,070 32,531 Total limited partners' interests in Operating Partnership and other redeemable noncontrolling interests balance at September 30 $ 47,426 $ 73,454 Fair Value Measurements We follow the framework established under accounting standard FASB ASC 820 for measuring fair value of non-financial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis but only in certain circumstances, such as a business combination or upon determination of an impairment. Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows: • Level 1 fair value inputs are quoted prices in active markets for identical instruments to which we have access. • Level 2 fair value inputs are inputs other than quoted prices included in Level 1 that are observable for similar instruments, either directly or indirectly, and appropriately consider counterparty creditworthiness in the valuations. • Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an instrument at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our 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. Recently Issued Accounting Pronouncements Adoption of New Standards On January 1, 2018, we adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) using the modified retrospective approach. ASU 2014-09 revised GAAP by offering a single comprehensive revenue recognition standard that supersedes nearly all existing GAAP revenue recognition guidance. The impacted revenue streams primarily consist of fees earned from management, development services provided to third parties, and other ancillary income earned from our properties. No adjustments were required upon adoption of this standard. We evaluated our revenue streams and less than 1% of our annual revenue was impacted by this new standard upon its initial adoption. Additionally, we adopted the clarified scope guidance of ASC 610-20, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" in conjunction with ASU 2014-09, using the modified retrospective approach. ASC 610-20 applies to the sale, transfer and derecognition of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales, and eliminates the guidance specific to real estate in ASC 360-20. With respect to full disposals, the recognition will generally be consistent with our current measurement and pattern of recognition. With respect to partial sales of real estate to joint ventures, the new guidance requires us to recognize a full gain where an equity investment is retained. These transactions could result in a basis difference as we will be required to measure our retained equity interest at fair value, whereas the joint venture may continue to measure the assets received at carryover basis. No adjustments were required upon adoption of this standard. During the nine months ended September 30, 2018, we sold our Trussville Promenade operating property in Birmingham, Alabama and our Memorial Commons operating property in Goldsboro, North Carolina in all cash transactions with no continuing future involvement. The gains recognized were less than 1% of our total revenue for the nine months ended September 30, 2018. As we do not have any continuing involvement in the operations of the operating properties, there was not a change in the accounting for the sales. In addition, we sold a controlling interest in three operating properties to a newly formed joint venture involving TH Real Estate. The Company calculated the gain in accordance with ASC 606 and ASC 610-20 that requires full gain recognition upon deconsolidation of a nonfinancial asset. The properties were sold for an agreed upon value of $99.8 million . Net proceeds from the sale were $89.0 million and a net gain of $7.8 million was recorded as a result of the sale. The Company contributed $10.0 million for a 20% ownership interest in the joint venture. On January 1, 2018 we adopted ASU 2016-15, Statement of Cash Flows (Topic 230), and ASU 2016-18, Restricted Cash , using a retrospective transition approach, which changed our statements of cash flows and related disclosures for all periods presented. ASU 2016-15 is intended to reduce diversity in practice with respect to how certain transactions are classified in the statement of cash flows and its adoption had no impact on our financial statements. ASU 2016-18 requires that a statement of cash flows explain the change during the period in total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The following is a summary of our cash, cash equivalents, and restricted cash total as presented in our statements of cash flows for the nine months ended September 30, 2018 and 2017: As of September 30, 2018 2017 Cash and cash equivalents $ 30,709 $ 32,465 Restricted cash 10,307 8,878 Total cash, cash equivalents, and restricted cash $ 41,016 41,343 For the nine months ended September 30, 2017, restricted cash related to cash flows provided by operating activities of $1.7 million and restricted cash related to cash flows provided by investing activities of $1.9 million were reclassified. Restricted cash primarily relates to cash held in escrows for payments of real estate taxes and property reserves for maintenance, insurance, or tenant improvements as required by our mortgage loans. New Standards Issued but Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases . ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making certain changes to lessor accounting, including the accounting for sales-type and direct financing leases. ASU 2016-02 will be effective for annual and interim reporting periods beginning on or after December 15, 2018, with early adoption permitted. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. Because of the adoption of ASU 2016-02, we expect common area maintenance reimbursements that are of a fixed nature to be recognized on a straight-line basis over the term of the lease. We also expect to recognize right of use assets on our balance sheet related to certain ground leases where we are the lessee. Upon adoption of the standard, we anticipate recognizing a right of use asset currently estimated to be between $30 million and $34 million . In addition to evaluating the impact of adopting the new accounting standard on our consolidated financial statements, we are evaluating our existing lease contracts, our current and future information system capabilities, and other variables. In July 2018, the FASB amended the new lease accounting standard to approve a new transition method and a lessor practical expedient for separating lease and non-lease components. This permits lessors to make an accounting policy election to not separate non-lease components, such as common area maintenance, of a contract from the leases to which they relate when specific criteria are met. The new leasing standard also amends ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers. Under ASC 340-40, incremental costs of obtaining a contract are recognized as an asset if the entity expects to recover them, which will reduce the leasing costs currently capitalized. Upon adoption of the new standard, we expect a reduction in certain capitalized costs and a corresponding increase in general, administrative, and other expense and a decrease in amortization expense on our consolidated statement of operations to be approximately $3 - $5 million , although the amount of such impact is highly dependent upon the leasing compensation structures in place at the time of adoption, which may ultimately differ from those assumed by this projection. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities . ASU 2017-02 better aligns a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 will be effective for annual and interim reporting periods beginning on or after December 15, 2018, with early adoption permitted using a modified retrospective transition method. This adoption method will require us to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While we continue to assess all potential impacts of the standard, we do not expect the adoption of ASU 2017-12 to have a material impact on our consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share or Unit	Earnings Per Share or Unit Basic earnings per share or unit is calculated based on the weighted average number of common shares or units outstanding during the period. Diluted earnings per share or unit is determined based on the weighted average common number of shares or units outstanding during the period combined with the incremental average common shares or units that would have been outstanding assuming the conversion of all potentially dilutive common shares or units into common shares or units as of the earliest date possible. Potentially dilutive securities include outstanding options to acquire common shares; Limited Partner Units, which may be exchanged for either cash or common shares, at the Parent Company’s option and under certain circumstances; units granted under our Outperformance Incentive Compensation Plan ("Outperformance Plan"); and deferred common share units, which may be credited to the personal accounts of non-employee trustees in lieu of the payment of cash compensation or the issuance of common shares to such trustees. Limited Partner Units have been omitted from the Parent Company’s denominator for computing diluted earnings per share since the effect of including these amounts in the denominator would have no dilutive impact. Approximately 2.0 million weighted average Limited Partner Units were outstanding for both the nine months ended September 30, 2018 and 2017. Due to the net loss allocable to common shareholders and Common Unit holders for the nine months ended September 30, 2018 and the three months ended September 30, 2017, no securities had a dilutive impact for these periods.

As of September 30, 2018, $337.4 million in variable rate debt is hedged for a weighted average 1.5 years. Mortgage indebtedness is collateralized by certain real estate properties and leases, and is generally due in monthly installments of interest and principal and matures over various terms through 2030. Variable interest rates on mortgage indebtedness are based on LIBOR plus spreads ranging from 150 to 160 basis points. At September 30, 2018 , the one-month LIBOR interest rate was 2.26% . Fixed interest rates on mortgage indebtedness range from 3.78% to 6.78% . Debt Issuance Costs Debt issuance costs are amortized on a straight-line basis over the terms of the respective loan agreements. The accompanying consolidated statements of operations include amortization of debt issuance costs as a component of interest expense as follows: Nine Months Ended 2018 2017 Amortization of debt issuance costs $ 2,220 $ 2,014 Unsecured Revolving Credit Facility and Unsecured Term Loans On April 24, 2018, the Company and Operating Partnership entered into the First Amendment (the “Amendment”) to the Fifth Amended and Restated Credit Agreement (the “Existing Credit Agreement,” and as amended by the Amendment, the “Amended Credit Agreement”), dated as of July 28, 2016, by and among the Operating Partnership, as borrower, the Company, as guarantor (pursuant to a springing guaranty, dated as of July 28, 2016), KeyBank National Association, as administrative agent, and the other lenders party thereto. The Amendment increases (i) the aggregate principal amount available under the unsecured revolving credit facility (the “Credit Facility”) from $500 million to $600 million , (ii) the amount of the letter of credit issuances the Operating Partnership may utilize under the Credit Facility from $50 million to $60 million , and (iii) swingline loan capacity from $50 million to $60 million in same day borrowings. Under the Amended Credit Agreement, the Operating Partnership has the option to increase the Credit Facility to $1.2 billion (increased from $1 billion under the Existing Credit Agreement) upon the Operating Partnership’s request, subject to certain conditions, including obtaining commitments from any one or more lenders, whether or not currently party to the Amended Credit Agreement, to provide such increased amounts. The Amendment extends the scheduled maturity date of the Credit Facility from July 28, 2020 to April 22, 2022 (which maturity date may be extended for up to two additional periods of six months at the Operating Partnership’s option subject to certain conditions). Among other things, the Amendment also improves the Operating Partnership’s leverage ratio calculation by changing the definition of capitalization rate to six and one-half percent ( 6.5% ) from six and three-fourths percent ( 6.75% ), which increases the Operating Partnership’s total asset value as calculated under the Amended Credit Agreement. As of September 30, 2018 , $23.1 million was outstanding under the Credit Facility. Additionally, we had letters of credit outstanding which totaled $4.1 million , against which no amounts were advanced as of September 30, 2018 . The amount that we may borrow under our Credit Facility is limited by the value of the assets in our unencumbered asset pool. As of September 30, 2018 , the value of the assets in our unencumbered asset pool, calculated pursuant to the Credit Facility agreement, was $1.4 billion . Considering outstanding borrowings on the line of credit, term loans, unsecured notes and letters of credit, we had $436.6 million available under our Credit Facility for future borrowings as of September 30, 2018 . Our ability to borrow under the Credit Facility is subject to our compliance with various restrictive and financial covenants, including with respect to liens, indebtedness, investments, dividends, mergers and asset sales. As of September 30, 2018 , we were in compliance with all such covenants. Senior Unsecured Notes The Operating Partnership has $550 million of senior unsecured notes maturing at various dates through September 2027 (the "Notes"). The Notes contain a number of customary financial and restrictive covenants. As of September 30, 2018 , we were in compliance with all such covenants. Other Debt Activity For the nine months ended September 30, 2018 , we had total new borrowings of $127.0 million and total repayments of $245.0 million . In addition to the items mentioned above, the remaining components of this activity were as follows: • We retired the $33.3 million loan secured by our Perimeter Woods operating property through a draw on our Credit Facility; • We retired the $33.0 million loan secured by our Killingly Commons operating property through a draw on our Credit Facility; • We retired the $4.3 million loan secured by our Whitehall Pike operating property and the $6.4 million loan secured by our Fishers Station redevelopment property utilizing cash flow from operations; • We borrowed $43.1 million on the Credit Facility to fund development activities, redevelopment activities, tenant improvement costs, and other working capital needs; • We used the $89.0 million of net proceeds from the formation of the TH Real Estate joint venture to pay down the Credit Facility; • We used the $63.0 million of net proceeds from the sale of two operating properties to pay down the Credit Facility; • We borrowed $10.0 million on the Credit Facility to partially redeem our partners' interest in the Territory joint venture; and • We made scheduled principal payments on indebtedness totaling $4.0 million . Fair Value of Fixed and Variable Rate Debt As of September 30, 2018 , the estimated fair value of our fixed rate debt was $1.0 billion compared to the book value of $1.1 billion . The fair value was estimated using Level 2 and 3 inputs with cash flows discounted at current borrowing rates for similar instruments, which ranged from 4.36% to 4.93% . As of September 30, 2018 , the fair value of variable rate debt was $497.7 million compared to the book value of $496.8 million . The fair value was estimated using Level 2 and 3 inputs with cash flows discounted at current borrowing rates for similar instruments, which ranged from 2.88% to 4.49% .

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments, Hedging Activities and Other Comprehensive Income	Derivative Instruments, Hedging Activities and Other Comprehensive Income In order to manage potential future variable interest rate risk, we enter into interest rate derivative agreements from time to time. All such agreements are designated as cash flow hedges. We do not use interest rate derivative agreements for trading or speculative purposes. The agreements with each of our derivative counterparties provide that, in the event of default on any of our indebtedness, we could also be declared in default on our derivative obligations. As of September 30, 2018 , we were party to various cash flow derivative agreements with notional amounts totaling $337.4 million . These derivative agreements effectively fix the interest rate underlying certain variable rate debt instruments over expiration dates through 2021 . Utilizing a weighted average interest rate spread over LIBOR on all variable rate debt resulted in fixing the weighted average interest rate at 3.72% . These interest rate derivative agreements are the only assets or liabilities that we record at fair value on a recurring basis. The valuation of these assets and liabilities is determined using widely accepted techniques including discounted cash flow analysis. These techniques consider the contractual terms of the derivatives (including the period to maturity) and use observable market-based inputs such as interest rate curves and implied volatilities. We also incorporate credit valuation adjustments into the fair value measurements to reflect nonperformance risk on both our part and that of the respective counterparties. We determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, although the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. As of September 30, 2018 and December 31, 2017 , we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined the credit valuation adjustments were not significant to the overall valuation of our derivatives. As a result, we determined our derivative valuations were classified within Level 2 of the fair value hierarchy. As of September 30, 2018 , the estimated fair value of our interest rate derivatives represented a net asset of $5.8 million . As of September 30, 2018 , $5.9 million was reflected in prepaid and other assets and $0.1 million was reflected in accounts payable and accrued expenses on the accompanying consolidated balance sheets. At December 31, 2017 , the estimated fair value of our interest rate hedges was a net asset of $2.4 million , including accrued interest of $0.1 million . As of December 31, 2017 , $3.1 million was reflected in prepaid and other assets and $0.7 million was reflected in accounts payable and accrued expenses on the accompanying consolidated balance sheets. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to earnings over time as the hedged items are recognized in earnings. Approximately $0.4 million was reclassified as a reduction to earnings during the nine months ended September 30, 2018, and $2.1 million was reclassified as a reduction to earnings during the nine months ended September 30, 2017 . As the interest payments on our hedges are made over the next 12 months, we estimate the decrease to interest expense to be $2.4 million , assuming the current LIBOR curve. Unrealized gains and losses on our interest rate derivative agreements are the only components of the change in accumulated other comprehensive income.

Deferred Revenue Disclosure [Abstract]
Deferred Revenue, Intangibles, Net and Other Liabilities	Deferred Revenue, Intangibles, Net and Other Liabilities Deferred revenue and other liabilities consist of the unamortized fair value of below market lease liabilities recorded in connection with purchase accounting, retainage payables for development and redevelopment projects, and tenant rent payments received in advance of the month in which they are due. The amortization of below market lease liabilities is recognized as revenue over the remaining life of the leases (including option periods for leases with below market renewal options) through 2046. Tenant rent payments received in advance are recognized as revenue in the period to which they apply, which is typically the month following their receipt. At September 30, 2018 and December 31, 2017 , deferred revenue, intangibles, net and other liabilities consisted of the following: September 30, December 31, Unamortized below market lease liabilities $ 72,237 $ 83,117 Retainage payables and other 3,154 3,954 Tenant rent payments received in advance 7,332 9,493 Total $ 82,723 $ 96,564 The amortization of below market lease intangibles is included as a component of minimum rent in the accompanying consolidated statements and was $7.5 million and $5.7 million for the nine months ended September 30, 2018 and 2017 , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Other Commitments and Contingencies We are not subject to any material litigation nor, to management’s knowledge, is any material litigation currently threatened against us. We are parties to routine litigation, claims, and administrative proceedings arising in the ordinary course of business. Management believes that such matters will not have a material adverse impact on our consolidated financial condition, results of operations or cash flows taken as a whole. We are obligated under various completion guarantees with certain lenders and lease agreements with tenants to complete all or portions of the development and redevelopment projects. We believe we currently have sufficient financing in place to fund these projects and expect to do so primarily through borrowings on the Credit Facility. In connection with the joint venture formed for the development of the Embassy Suites at Notre Dame, we provided a repayment guaranty on a $33.8 million construction loan, of which our share is $11.8 million (reflecting our 35% ownership interest in the hotel project). The outstanding loan balance as of September 30, 2018 is $29.3 million and our share is $10.3 million . As of September 30, 2018 , we had outstanding letters of credit totaling $4.1 million . At that date, there were no amounts advanced against these instruments.

Discontinued Operations and Disposal Groups [Abstract]
Disposals of Operating Properties and Recording of Impairment Charges	Disposals of Operating Properties and Recording of Impairment Charges As of September 30, 2018, the Company has classified its Whitehall Pike operating property as held for sale. The Company has committed to a plan to sell this asset, and it expects that the sale of this asset will be completed in one year at a sales price that exceeds its carrying value. During the three months ended June 30, 2018, we contributed our Livingston Shopping Center, Plaza Volente, and Tamiami Crossing operating properties to the TH Real Estate joint venture (see Note 2) for an agreed upon value of $99.8 million in exchange for a 20% ownership interest and $89.0 million in net proceeds. This transaction resulted in a net gain of $7.8 million . The Company calculated the gain in accordance with ASC 606 and ASC 610-20 that require full gain recognition upon deconsolidation of a nonfinancial asset. This gain was calculated as the fair value of the properties (based upon the sales price for the 80% of interests) less the aggregate carrying value. The retained 20% equity method investment was recorded at fair value as of the transaction date of June 29, 2018, or $10.0 million . As of June 30, 2018, in connection with the preparation and review of the financial statements, we evaluated two properties for impairment and recorded a $14.8 million impairment charge due to changes during the quarter in facts and circumstances underlying the Company's expected future hold period of these properties. A shortening of an expected future hold period is considered an impairment indicator under applicable accounting rules, and this indicator caused us to further evaluate the carrying value of these properties. We concluded the estimated undiscounted cash flows over the expected holding period did not exceed the carrying value of these assets, leading to the charge during the quarter. We estimated the fair value using Level 3 inputs within the fair value hierarchy, primarily using the market approach. We compared the estimated aggregate fair value of $30.4 million to the carrying values, which resulted in the recording of a non-cash impairment charge of $14.8 million for the three months ended June 30, 2018. During the three months ended March 31, 2018, we sold our Trussville Promenade operating property in Birmingham, Alabama, and our Memorial Commons operating property in Goldsboro, North Carolina, for aggregate gross proceeds of $63.0 million and a net gain of $0.5 million . During the three months ended June 30, 2017, we sold our Clay Marketplace operating property in Birmingham, Alabama, our Shops at Village Walk operating property in Fort Myers, Florida, and our Wheatland Towne Crossing operating property in Dallas, Texas for aggregate gross proceeds of $54.6 million and a net gain of $6.3 million During the three months ended March 31, 2017, we sold our Cove Center operating property in Stuart, Florida, for gross proceeds of $23.1 million and a net gain of $8.9 million . In connection with the preparation and review of the financial statements as of and for the three months ended March 31, 2018, we evaluated an operating property for impairment and recorded a $24.1 million impairment charge due to changes during the quarter in facts and circumstances underlying the Company’s expected future hold period of this property. A shortening of an expected future hold period is considered an impairment indicator under applicable accounting rules, and this indicator caused us to further evaluate the carrying value of this property. We concluded the estimated undiscounted cash flows over the expected holding period did not exceed the carrying value of a certain asset, leading to the charge during the quarter. We estimated the fair value of the property to be $24.3 million using Level 3 inputs within the fair value hierarchy, primarily using the market approach. We compared the estimated fair value to the carrying value, which resulted in the recording of a non-cash impairment charge of $24.1 million for the three months ended March 31, 2018. This property was contributed to the TH Real Estate joint venture. In connection with the preparation and review of the March 31, 2017 financial statements, we evaluated an operating property for impairment due to the shortening of the intended holding period. We concluded the estimated undiscounted cash flows over the expected holding period did not exceed the carrying value of the asset. The Company estimated the fair value of the property to be $26.0 million using Level 3 inputs within the fair value hierarchy, primarily using the market approach. We compared the fair value measurement to the carrying value, which resulted in the recording of a non-cash impairment charge of $7.4 million for the three months ended March 31, 2017.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Unsecured Term Loan On October 25, 2018, the Operating Partnership entered into a Term Loan Agreement with KeyBank National Association as Administrative Agent, and the other lenders party thereto, providing for an unsecured term loan facility of up to $250 million (the “Term Loan”), which may be increased to $300 million subject to certain conditions, including lender commitments. The Term Loan has a scheduled maturity date of October 24, 2025, which maturity date may be extended for up to three additional periods of one year. The Term Loan ranks pari passu with the Operating Partnership’s existing $600 million unsecured revolving credit facility and $200 million unsecured term loan facility. Subject to certain exceptions, the Term Loan will bear interest at a rate of, at the Operating Partnership’s election, LIBOR plus an applicable margin of 200 to 255 basis points or a base rate plus an applicable margin of 100 to 155 basis points, in each case depending on the Operating Partnership’s leverage ratio. The Operating Partnership made a draw on the Term Loan in the amount of $250 million on October 25, 2018. In connection with that closing, the Company paid $200.5 million to pay off all outstanding obligations and fees under the term loan agreement, dated as of October 26, 2015, among the Operating Partnership, KeyBank National Association as Administrative Agent, and the other lenders party thereto. Other proceeds of the Term Loan will be used by the Operating Partnership for general corporate purposes. Property Disposition On November 1, 2018, the Company sold Lake Lofts at Deerwood for gross proceeds of approximately $20.0 million . These proceeds were utilized to pay down the Credit Facility.

Basis of Presentation, Consolidation, Investments in Joint Ventures, and Noncontrolling Interests (Policies)	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation and Investments in Joint Ventures	Consolidation and Investments in Joint Ventures The accompanying financial statements are presented on a consolidated basis and include all accounts of the Parent Company, the Operating Partnership, the taxable REIT subsidiary of the Operating Partnership, subsidiaries of the Operating Partnership that are controlled and any variable interest entities (“VIEs”) in which the Operating Partnership is the primary beneficiary. In general, a VIE is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) has equity investors that do not provide sufficient financial resources for the entity to support its activities, (b) does not have equity investors with voting rights or (c) has equity investors whose votes are disproportionate from their economics and substantially all of the activities are conducted on behalf of the investor with disproportionately fewer voting rights. The Operating Partnership accounts for properties that are owned by joint ventures in accordance with the consolidation guidance. The Operating Partnership evaluates each joint venture and determines first whether to follow the VIE or the voting interest entity ("VOE") model. Once the appropriate consolidation model is identified, the Operating Partnership then evaluates whether it should consolidate the joint venture. Under the VIE model, the Operating Partnership consolidates an entity when it has (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and (ii) the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. Under the VOE model, the Operating Partnership consolidates an entity when (i) it controls the entity through ownership of a majority voting interest if the entity is not a limited partnership or (ii) it controls the entity through its ability to remove the other partners or owners in the entity, at its discretion, when the entity is a limited partnership. In determining whether to consolidate a VIE with the Operating Partnership, we consider all relationships between the Operating Partnership and the applicable VIE, including development agreements, management agreements and other contractual arrangements, in determining whether we have the power to direct the activities of the VIE that most significantly affect the VIE's performance. As of September 30, 2018 , we owned investments in three consolidated joint ventures that were VIEs in which the partners did not have substantive participating rights and we were the primary beneficiary. As of this date, these VIEs had total debt of $205.7 million , which were secured by assets of the VIEs totaling $444.2 million . The Operating Partnership guarantees the debts of these VIEs. On June 29, 2018, the Company formed a joint venture involving TH Real Estate (the "TH Real Estate joint venture"). The Company sold three properties to the joint venture valued in the aggregate at $99.8 million and, after considering third party debt obtained by the venture upon formation, the Company contributed $10.0 million for a 20% noncontrolling ownership interest in the venture. The Company serves as the operating member responsible for day-to-day management of the properties and receives property management and leasing fees. Both members have substantive participating rights over major decisions that impact the economics and operations of the joint venture. The Company is accounting for the joint venture on the equity method as it has the ability to exercise influence, but not control over operating and financial policies. The Operating Partnership is considered a VIE as the limited partners do not hold kick-out rights or substantive participating rights. The Parent Company consolidates the Operating Partnership as it is the primary beneficiary in accordance with the VIE model.
Income Taxes	Income Taxes and REIT Compliance Parent Company The Parent Company, which is considered a corporation for federal income tax purposes, has been organized and intends to continue to operate in a manner that will enable it to maintain its qualification as a REIT for federal income tax purposes. As a result, it generally will not be subject to federal income tax on the earnings that it distributes to the extent it distributes its “REIT taxable income” (determined before the deduction for dividends paid and excluding net capital gains) to shareholders of the Parent Company and meets certain other requirements on a recurring basis. To the extent that it satisfies this distribution requirement, but distributes less than 100% of its taxable income, it will be subject to federal corporate income tax on its undistributed REIT taxable income. REITs are subject to a number of organizational and operational requirements. If the Parent Company fails to qualify as a REIT in any taxable year, it will be subject to federal income tax on its taxable income at regular corporate rates for a period of four years following the year in which qualification is lost. We may also be subject to certain federal, state and local taxes on our income and property and to federal income and excise taxes on our undistributed taxable income even if the Parent Company does qualify as a REIT. The Operating Partnership intends to continue to make distributions to the Parent Company in amounts sufficient to assist the Parent Company in adhering to REIT requirements and maintaining its REIT status. We have elected to treat Kite Realty Holdings, LLC as a taxable REIT subsidiary of the Operating Partnership, and we may elect to treat other subsidiaries as taxable REIT subsidiaries in the future. This election enables us to receive income and provide services that would otherwise be impermissible for a REIT. Deferred tax assets and liabilities are established for temporary differences between the financial reporting bases and the tax bases of assets and liabilities at the tax rates expected to be in effect when the temporary differences reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. Operating Partnership The allocated share of income and loss, other than the operations of our taxable REIT subsidiary, is included in the income tax returns of the Operating Partnership's partners. Accordingly, the only federal income taxes included in the accompanying consolidated financial statements are in connection with the Operating Partnership's taxable REIT subsidiary.
Noncontrolling Interests	Noncontrolling Interests We report the non-redeemable noncontrolling interests in subsidiaries as equity, and the amount of consolidated net income attributable to these noncontrolling interests is set forth separately in the consolidated financial statements. The non-redeemable noncontrolling interests in consolidated properties for the nine months ended September 30, 2018 and 2017 were as follows: 2018 2017 Noncontrolling interests balance January 1 $ 698 $ 692 Net income allocable to noncontrolling interests, — 6 Noncontrolling interests balance at September 30 $ 698 $ 698 Redeemable Noncontrolling Interests - Limited Partners Limited Partner Units are redeemable noncontrolling interests in the Operating Partnership. We classify redeemable noncontrolling interests in the Operating Partnership in the accompanying consolidated balance sheets outside of permanent equity because we may be required to pay cash to holders of Limited Partner Units upon redemption of their interests in the Operating Partnership or deliver registered shares upon their conversion. The carrying amount of the redeemable noncontrolling interests in the Operating Partnership is reflected at the greater of historical book value or redemption value with a corresponding adjustment to additional paid-in capital. At September 30, 2018 , the redemption value of the redeemable noncontrolling interests did not exceed the historical book value, and the balance was accordingly adjusted to historical book value. At December 31, 2017, the redemption value of the redeemable noncontrolling interests exceeded the historical book value, and the balance was accordingly adjusted to redemption value. We allocate net operating results of the Operating Partnership after noncontrolling interests in the consolidated properties based on the partners’ respective weighted average ownership interest. We adjust the redeemable noncontrolling interests in the Operating Partnership at the end of each reporting period to reflect their interests in the Operating Partnership or redemption value. This adjustment is reflected in our shareholders’ and Parent Company's equity. For the three and nine months ended September 30, 2018 and 2017 , the weighted average interests of the Parent Company and the limited partners in the Operating Partnership were as follows: Three Months Ended Nine Months Ended 2018 2017 2018 2017 Parent Company’s weighted average basic interest in 97.6 % 97.7 % 97.6 % 97.7 % Limited partners' weighted average basic interests in 2.4 % 2.3 % 2.4 % 2.3 % At September 30, 2018 , the Parent Company's interest and the limited partners' redeemable noncontrolling ownership interests in the Operating Partnership were 97.6% and 2.4% . At December 31, 2017, the Parent Company's interest and the limited partners' redeemable noncontrolling ownership interests in the Operating Partnership were 97.7% and 2.3% . Concurrent with the Parent Company’s initial public offering and related formation transactions, certain individuals received Limited Partner Units of the Operating Partnership in exchange for their interests in certain properties. The limited partners have the right to redeem Limited Partner Units for cash or, at the Parent Company's election, common shares of the Parent Company in an amount equal to the market value of an equivalent number of common shares of the Parent Company at the time of redemption. Such common shares must be registered, which is not fully in the Parent Company’s control. Therefore, the limited partners’ interest is not reflected in permanent equity. The Parent Company also has the right to redeem the Limited Partner Units directly from the limited partner in exchange for either cash in the amount specified above or a number of its common shares equal to the number of Limited Partner Units being redeemed. There were 2,048,849 and 1,974,830 Limited Partner Units outstanding as of September 30, 2018 and December 31, 2017 , respectively. The increase in Limited Partner Units outstanding from December 31, 2017 is due to non-cash compensation awards made to our executive officers in the form of Limited Partner Units. Redeemable Noncontrolling Interests - Subsidiaries Prior to the merger with Inland Diversified Real Estate Trust, Inc. ("Inland Diversified") in 2014, Inland Diversified formed joint ventures with the previous owners of certain properties and issued Class B units in three joint ventures that indirectly own those properties. The Class B units related to two of these three joint ventures remain outstanding and are accounted for as noncontrolling interests in these properties. The Class B units related to the Territory Portfolio joint venture became redeemable at the respective partner’s election in March 2017 and are discussed further below. The remaining Class B units relate to our Crossing at Killingly Commons joint venture will become redeemable at the partner's election in October 2022 and the fulfillment of certain redemption criteria. Beginning in November 2022, the Class B units can be redeemed at the election of either of our partner or us for cash or Limited Partner Units in the Operating Partnership. None of the issued Class B units have a maturity date, and none are mandatorily redeemable unless either party has elected for the units to be redeemed. We consolidate these joint ventures because we control the decision making of each of the joint ventures and our joint venture partners have limited protective rights. In February 2018, we received notice from our partners in the Territory Portfolio joint venture of their intent to exercise their right to redeem their remaining $22.0 million of Class B units for cash. The amount that will be redeemed was reclassified from Limited partners' interests in Operating Partnership and other redeemable noncontrolling interests to accounts payable and accrued expenses in the consolidated balance sheets. The Company redeemed $10 million of the interest on August 7, 2018. The Company can determine the timing of the closing for the redemption for the remaining $12 million , but it must occur before November 8, 2018. We classify the remainder of the redeemable noncontrolling interests in certain subsidiaries in the accompanying consolidated balance sheets outside of permanent equity because, under certain circumstances, we may be required to pay cash to Class B unitholders in specific subsidiaries upon redemption of their interests. The carrying amount of these redeemable noncontrolling interests is required to be reflected at the greater of initial book value or redemption value with a corresponding adjustment to additional paid-in capital.
Fair Value Measurements	Fair Value Measurements We follow the framework established under accounting standard FASB ASC 820 for measuring fair value of non-financial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis but only in certain circumstances, such as a business combination or upon determination of an impairment. Assets and liabilities recorded at fair value on the consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows: • Level 1 fair value inputs are quoted prices in active markets for identical instruments to which we have access. • Level 2 fair value inputs are inputs other than quoted prices included in Level 1 that are observable for similar instruments, either directly or indirectly, and appropriately consider counterparty creditworthiness in the valuations. • Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an instrument at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Our 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.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Adoption of New Standards On January 1, 2018, we adopted Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) using the modified retrospective approach. ASU 2014-09 revised GAAP by offering a single comprehensive revenue recognition standard that supersedes nearly all existing GAAP revenue recognition guidance. The impacted revenue streams primarily consist of fees earned from management, development services provided to third parties, and other ancillary income earned from our properties. No adjustments were required upon adoption of this standard. We evaluated our revenue streams and less than 1% of our annual revenue was impacted by this new standard upon its initial adoption. Additionally, we adopted the clarified scope guidance of ASC 610-20, "Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets" in conjunction with ASU 2014-09, using the modified retrospective approach. ASC 610-20 applies to the sale, transfer and derecognition of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales, and eliminates the guidance specific to real estate in ASC 360-20. With respect to full disposals, the recognition will generally be consistent with our current measurement and pattern of recognition. With respect to partial sales of real estate to joint ventures, the new guidance requires us to recognize a full gain where an equity investment is retained. These transactions could result in a basis difference as we will be required to measure our retained equity interest at fair value, whereas the joint venture may continue to measure the assets received at carryover basis. No adjustments were required upon adoption of this standard. During the nine months ended September 30, 2018, we sold our Trussville Promenade operating property in Birmingham, Alabama and our Memorial Commons operating property in Goldsboro, North Carolina in all cash transactions with no continuing future involvement. The gains recognized were less than 1% of our total revenue for the nine months ended September 30, 2018. As we do not have any continuing involvement in the operations of the operating properties, there was not a change in the accounting for the sales. In addition, we sold a controlling interest in three operating properties to a newly formed joint venture involving TH Real Estate. The Company calculated the gain in accordance with ASC 606 and ASC 610-20 that requires full gain recognition upon deconsolidation of a nonfinancial asset. The properties were sold for an agreed upon value of $99.8 million . Net proceeds from the sale were $89.0 million and a net gain of $7.8 million was recorded as a result of the sale. The Company contributed $10.0 million for a 20% ownership interest in the joint venture. On January 1, 2018 we adopted ASU 2016-15, Statement of Cash Flows (Topic 230), and ASU 2016-18, Restricted Cash , using a retrospective transition approach, which changed our statements of cash flows and related disclosures for all periods presented. ASU 2016-15 is intended to reduce diversity in practice with respect to how certain transactions are classified in the statement of cash flows and its adoption had no impact on our financial statements. ASU 2016-18 requires that a statement of cash flows explain the change during the period in total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The following is a summary of our cash, cash equivalents, and restricted cash total as presented in our statements of cash flows for the nine months ended September 30, 2018 and 2017: As of September 30, 2018 2017 Cash and cash equivalents $ 30,709 $ 32,465 Restricted cash 10,307 8,878 Total cash, cash equivalents, and restricted cash $ 41,016 41,343 For the nine months ended September 30, 2017, restricted cash related to cash flows provided by operating activities of $1.7 million and restricted cash related to cash flows provided by investing activities of $1.9 million were reclassified. Restricted cash primarily relates to cash held in escrows for payments of real estate taxes and property reserves for maintenance, insurance, or tenant improvements as required by our mortgage loans. New Standards Issued but Not Yet Adopted In February 2016, the FASB issued ASU 2016-02, Leases . ASU 2016-02 amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making certain changes to lessor accounting, including the accounting for sales-type and direct financing leases. ASU 2016-02 will be effective for annual and interim reporting periods beginning on or after December 15, 2018, with early adoption permitted. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. Because of the adoption of ASU 2016-02, we expect common area maintenance reimbursements that are of a fixed nature to be recognized on a straight-line basis over the term of the lease. We also expect to recognize right of use assets on our balance sheet related to certain ground leases where we are the lessee. Upon adoption of the standard, we anticipate recognizing a right of use asset currently estimated to be between $30 million and $34 million . In addition to evaluating the impact of adopting the new accounting standard on our consolidated financial statements, we are evaluating our existing lease contracts, our current and future information system capabilities, and other variables. In July 2018, the FASB amended the new lease accounting standard to approve a new transition method and a lessor practical expedient for separating lease and non-lease components. This permits lessors to make an accounting policy election to not separate non-lease components, such as common area maintenance, of a contract from the leases to which they relate when specific criteria are met. The new leasing standard also amends ASC 340-40, Other Assets and Deferred Costs - Contracts with Customers. Under ASC 340-40, incremental costs of obtaining a contract are recognized as an asset if the entity expects to recover them, which will reduce the leasing costs currently capitalized. Upon adoption of the new standard, we expect a reduction in certain capitalized costs and a corresponding increase in general, administrative, and other expense and a decrease in amortization expense on our consolidated statement of operations to be approximately $3 - $5 million , although the amount of such impact is highly dependent upon the leasing compensation structures in place at the time of adoption, which may ultimately differ from those assumed by this projection. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities . ASU 2017-02 better aligns a company’s financial reporting for hedging activities with the economic objectives of those activities. ASU 2017-12 will be effective for annual and interim reporting periods beginning on or after December 15, 2018, with early adoption permitted using a modified retrospective transition method. This adoption method will require us to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. While we continue to assess all potential impacts of the standard, we do not expect the adoption of ASU 2017-12 to have a material impact on our consolidated financial statements.
