Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Principles of Consolidation	Organization and Significant Accounting Policies General Regency Centers Corporation (the “Parent Company”) began its operations as a Real Estate Investment Trust (“REIT”) in 1993 and is the general partner of Regency Centers, L.P. (the “Operating Partnership”). The Parent Company engages in the ownership, management, leasing, acquisition, and development of retail shopping centers through the Operating Partnership. The Parent Company has no other assets other than through its investment in the Operating Partnership, and its only liabilities are the unsecured notes assumed from the merger with Equity One, Inc. ("Equity One"), which are co-issued and guaranteed by the Operating Partnership. The Parent Company guarantees all of the unsecured debt of the Operating Partnership. On March 1, 2017, Regency completed its merger with Equity One, whereby Equity One merged with and into Regency, with Regency continuing as the surviving public company. Under the terms of the Merger Agreement, each Equity One stockholder received 0.45 of a newly issued share of Regency common stock for each share of Equity One common stock owned immediately prior to the effective time of the merger, resulting in the issuance of approximately 65.5 million shares of Regency common stock to effect the merger. As of September 30, 2017 , the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owned 313 retail shopping centers and held partial interests in an additional 114 retail shopping centers through unconsolidated investments in real estate partnerships (also referred to as "joint ventures" or "investment partnerships"). The consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary to fairly state the results for the interim periods presented. These adjustments are considered to be of a normal recurring nature. Consolidation The Company consolidates properties that are wholly owned and properties where it owns less than 100%, but which it controls. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIEs"). For joint ventures that are determined to be a VIE, the Company consolidates the entity where it is deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company's determination of the primary beneficiary considers all relationships between it and the VIE, including management agreements and other contractual arrangements. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2017 , the Parent Company owned approximately 99.8% of the outstanding common Partnership Units of the Operating Partnership with the remaining limited Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities of the Operating Partnership. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company’s only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages. Segment Reporting The Company's business is investing in retail shopping centers through direct ownership or through joint ventures. The Company actively manages its portfolio of retail shopping centers and may from time to time make decisions to sell lower performing properties not meeting its long-term investment objectives. The proceeds from sales are reinvested into higher quality retail shopping centers, through acquisitions or new developments, which management believes will generate sustainable revenue growth and attractive returns. It is management's intent that all retail shopping centers will be owned or developed for investment purposes. The Company's revenues and net income are generated from the operation of its investment portfolio. The Company also earns fees for services provided to manage and lease retail shopping centers owned through joint ventures. The Company's portfolio is located throughout the United States. Management does not distinguish or group its operations on a geographical basis for purposes of allocating resources or capital. The Company reviews operating and financial data for each property on an individual basis; therefore, the Company defines an operating segment as its individual properties. The individual properties have been aggregated into one reportable segment based upon their similarities with regard to both the nature and economics of the centers, tenants and operational processes, as well as long-term average financial performance. Goodwill Goodwill, which is included within Other assets in the accompanying Consolidated Balance Sheets, represents the excess of the purchase price consideration for the Equity One merger over the fair value of the assets acquired and liabilities assumed, and reflects expected synergies from combining Regency's and Equity One's operations. The Company accounts for goodwill in accordance with the Intangibles - Goodwill and Other Topic of the FASB ASC, and allocates its goodwill to the reporting units, which have been determined to be at the individual property level. The Company will perform an impairment evaluation of its goodwill at least annually, in November of each year. The goodwill impairment evaluation may be completed through a qualitative or quantitative approach. Under a qualitative approach, the impairment review for goodwill consists of an assessment of whether it is more-likely-than-not that the property’s fair value is less than its carrying value. If a qualitative approach indicates it is more likely-than-not that the estimated carrying value of a property exceeds its fair value, or if the Company chooses to bypass the qualitative approach for any property, the Company will perform the quantitative approach described below. The first step of the quantitative approach consists of estimating the fair value of each property using discounted projected future cash flows and comparing those estimated fair values with the carrying values, which include the allocated goodwill. If the estimated fair value is less than the carrying value, a second step is performed to compute the amount of the impairment, if any, by determining an implied fair value of goodwill. The determination of each property’s implied fair value of goodwill requires allocation of the estimated fair value of the property to its assets and liabilities. Any unallocated fair value represents the implied fair value of goodwill which is compared to its corresponding carrying value. Real Estate Partnerships As of September 30, 2017 , Regency has an ownership interest in 125 properties through partnerships, of which 11 are consolidated. Our partners in these ventures include institutional investors, other real estate developers and/or operators, and individual parties who help Regency source transactions for development and investment (the "Partners" or "limited partners"). Regency has a variable interest in these entities through its equity interests. As managing member, Regency maintains the books and records and typically provides leasing and property management to the partnerships. The partners’ level of involvement varies from protective decisions (debt, bankruptcy, selling primary asset(s) of business) to involvement in approving leases, operating budgets, and capital budgets. • Those partnerships for which the Partners only have protective rights are considered VIEs under ASC 810, Consolidation. Regency is the primary beneficiary of these VIEs as Regency has power over these partnerships and they operate primarily for the benefit of Regency. As such, Regency consolidates these entities and reports the limited partners’ interest as noncontrolling interests. The operations of the VIEs are funded with cash flows generated by the properties, or in the case of developments, with capital contributions or third party construction loans. Regency does not provide financial support to the VIEs beyond the terms stipulated in the partnership operating agreements. • Those partnerships for which the partners are involved in the day to day decisions and do not have any other aspects that would cause them to be considered VIEs, are evaluated for consolidation using the voting interest model. ◦ Those partnerships in which Regency has a controlling financial interest are consolidated and the limited partners’ ownership interest and share of net income is recorded as noncontrolling interest. ◦ Those partnerships in which Regency does not have a controlling financial interest are accounted for using the equity method, and its ownership interest is recognized through single-line presentation as Investments in real estate partnerships in the Consolidated Balance Sheet, and Equity in income of investments in real estate partnerships in the Consolidated Statements of Operations. Cash distributions of earnings from operations of investments in real estate partnerships are presented in cash flows provided by operating activities in the accompanying Consolidated Statements of Cash Flows. Cash distributions from the sale of a property or loan proceeds received from the placement of debt on a property included in investments in real estate partnerships are presented in cash flows provided by investing activities in the accompanying Consolidated Statements of Cash Flows. The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is either (1) accreted to income and recorded in Equity in income of investments in real estate partnerships in the accompanying Consolidated Statements of Operations over the expected useful lives of the properties and other intangible assets, which range in lives from 10 to 40 years, or (2) recognized upon sale of the underlying asset(s) or settlement of underlying liabilities, or (3) recognized at liquidation if the joint venture agreement includes a unilateral right to elect to dissolve the real estate partnership and, upon such an election, receive a distribution in-kind. The assets of the partnerships are restricted to the use of the partnerships and cannot be used as security by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of the partnerships. The major classes of assets, liabilities, and non-controlling equity interests held by the Company's VIEs, exclusive of the Operating Partnership as a whole, are as follows: (in thousands) September 30, 2017 December 31, 2016 Assets Real estate assets, net $ 93,821 86,440 Cash and cash equivalents 4,053 3,444 Liabilities Notes payable 12,691 8,175 Equity Limited partners’ interests in consolidated partnerships 17,604 17,565

As a result of consolidation, the Company recorded the partner's non-controlling interest of $8.4 million in Limited partners' interests in consolidated partnerships in the accompanying Consolidated Balance Sheets. Equity One Merger General On March 1, 2017, Regency completed its merger with Equity One, a NYSE listed shopping center company, whereby Equity One merged with and into Regency, with Regency continuing as the surviving public company. Under the terms of the Merger Agreement, each Equity One stockholder received 0.45 of a newly issued share of Regency common stock for each share of Equity One common stock owned immediately prior to the effective time of the merger resulting in approximately 65.5 million Regency common shares being issued to effect the merger. The following table provides the components that make up the total purchase price for the Equity One merger: (in thousands, except stock price) Purchase Price Shares of common stock issued for merger 65,379 Closing stock price on March 1, 2017 $ 68.40 Value of common stock issued for merger $ 4,471,808 Debt repaid 716,278 Other cash payments 5,019 Total purchase price $ 5,193,105 As part of the merger, Regency acquired 121 properties, including 8 properties held through co-investment partnerships. The consolidated net assets and results of operations of Equity One are included in the consolidated financial statements from the closing date, March 1, 2017, going forward and resulted in the following impact to Revenues and Net income attributable to common stockholders for the three and nine months ended September 30, 2017 : September 30, 2017 (in thousands) Three months ended Nine months ended Increase in total revenues $ 102,437 238,250 Increase in net income attributable to common stockholders 23,517 52,981 The Company incurred $1.2 million and $75.6 million of merger-related transaction costs during the three and nine months ended September 30, 2017 , respectively, which are recorded in Other operating expenses in the accompanying Consolidated Statements of Operations. There were no such merger costs incurred during the same periods of 2016 . Provisional Purchase Price Allocation of Merger The Equity One merger has been accounted for using the acquisition method of accounting in accordance with ASC 805, Business Combinations, which requires, among other things, that the assets acquired and liabilities assumed be recognized at their acquisition date fair values. The acquired assets and assumed liabilities of an acquired operating property generally include, but are not limited to: land, buildings and improvements, identified tangible and intangible assets and liabilities associated with in-place leases, including tenant improvements, leasing costs, value of above-market and below-market leases, and value of acquired in-place leases. This methodology requires estimating an “as-if vacant” fair value of the physical property, which includes land, building, and improvements and also determining the estimated fair value of identifiable intangible assets and liabilities, considering the following categories: (i) value of in-place leases, and (ii) above and below-market value of in-place leases. The excess of the purchase price consideration over the fair value of assets acquired and liabilities assumed results in goodwill in the business combination, which reflects expected synergies from combining Regency's and Equity One's operations. The goodwill is not expected to be deductible for tax purposes. The provisional fair market value of the acquired operating properties is based on a valuation prepared by Regency with assistance of a third party valuation specialist. The third party used stabilized NOI and market specific capitalization and discount rates as the primary inputs in determining the fair value of the real estate assets. Management reviewed the inputs used by the third party specialist as well as the allocation of the purchase price to ensure reasonableness and that the procedures were performed in accordance with management's policy. Management and the third party valuation specialist have prepared their provisional fair value estimates for each of the operating properties acquired, but are still in process of reviewing all of the underlying inputs and assumptions; therefore, the purchase price and its allocation, in their entirety, are not yet complete as of the date of this filing but have been updated to reflect management's current best estimates of fair values as of the acquisition date . Once the purchase price and allocation are complete, an additional adjustment to the purchase price or allocation may occur. The following table summarizes the current provisional purchase price allocation based on the Company's valuation, including estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed: (in thousands) Provisional Purchase Price Allocation Land $ 2,914,790 Building and improvements 2,699,937 Properties in development 68,744 Properties held for sale 19,600 Investments in unconsolidated real estate partnerships 103,566 Real estate assets 5,806,637 Cash, accounts receivable and other assets 112,271 Intangible assets 460,541 Goodwill 302,303 Total assets acquired 6,681,752 Notes payable 757,399 Accounts payable, accrued expenses, and other liabilities 121,441 Lease intangible liabilities 609,807 Total liabilities assumed 1,488,647 Total purchase price $ 5,193,105 During the three months ended September 30, 2017 , the Company adjusted the provisional purchase price allocation to reflect current best estimates of fair values of the acquired operating properties, based on the valuation process described above. These adjustments resulted in the following increases (decreases) to earnings during the three months ended September 30, 2017 that would have been recognized in previous periods if the adjustments to provisional amounts were recognized as of the acquisition date: (in thousands) Three months ended September 30, 2017 decrease in Minimum rent $ (567 ) decrease in Depreciation and amortization 1,645 decrease in Operating and maintenance 142 Net increase to earnings of provisional purchase price allocation adjustments $ 1,220 The allocation of the purchase price is based on management’s assessment, which may change in the future as more information becomes available. Subsequent adjustments made to the purchase price allocation upon completion of the Company's fair value assessment process will not exceed one year from the acquisition date. The allocation of the purchase price described above requires a significant amount of judgment and represents management's best estimate of the fair value as of the acquisition date. The following table details the provisional weighted average amortization and net accretion periods, in years, of the major classes of intangible assets and intangible liabilities arising from the Equity One merger: (in years) Weighted Average Amortization Period Assets: In-place leases 11.0 Above-market leases 8.9 Below-market ground leases 54.6 Liabilities: Acquired lease intangible liabilities 24.8 Pro forma Information (unaudited) The following unaudited pro forma financial data includes the incremental revenues, operating expenses, depreciation and amortization, and costs of the Equity One acquisition as if it had occurred on January 1, 2016: Three months ended September 30, Nine months ended September 30, (in thousands, except per share data) 2017 2016 2017 2016 Total revenues $ 262,708 251,823 788,345 752,121 Income (loss) from operations (1) 63,537 3,358 190,112 (4,560 ) Net income (loss) attributable to common stockholders (1) 59,621 (1,907 ) 171,795 (21,744 ) Income (loss) per common share - basic $ 0.35 (0.01 ) 1.01 (0.13 ) Income (loss) per common share - diluted 0.35 (0.01 ) 1.01 (0.13 ) (1) The pro forma earnings for the three and nine months ended September 30, 2017, were adjusted to exclude $1.2 million and $98.5 million of merger costs, respectively, while 2016 pro forma earnings were adjusted to include all merger costs during the first quarter of 2016.

Three of these variable rate loans have interest rate swaps in place to fix the interest rates at a range of 2.8% to 4.07% (2) Weighted average effective and contractual rate for the Line is calculated based on a fully drawn Line balance. During January 2017, the Company issued $650.0 million of senior unsecured public notes as follows: • $300.0 million of 4.4% senior unsecured public notes due in 2047, which priced at 99.110% . The Company used the net proceeds to redeem all of the outstanding shares of its $250 million 6.625% Series 6 preferred stock on February 16, 2017 and to pay down the balance of the Line. • $350.0 million of 3.6% senior unsecured public notes due in 2027, which priced at 99.741% . The Company used the net proceeds to repay a $250.0 million Equity One term loan upon the effective date of the merger and to pay merger related transaction costs. During June 2017, the Company issued an additional $300.0 million of senior unsecured public notes under the same terms as the January offering noted above as follows: • $125.0 million of 4.4% senior unsecured public notes due in 2047, which priced at 100.784% , with proceeds used to redeem all of the outstanding shares of its $75.0 million 6.000% Series 7 preferred stock on August 23, 2017, with the balance used to pay down the Line. • $175.0 million of 3.6% senior unsecured public notes due in 2027, which priced at 100.379% , with proceeds used to retire $112.0 million of mortgage loans with interest rates ranging from 7.0% to 7.8% on various properties, with the balance used to pay down the Line. The Company completed the following additional debt transactions in connection with the Equity One merger: • Increased the size of its Line commitment to $1.0 billion with an accordion feature permitting the Company to request an increase in the facility of up to an additional $500 million . • Completed a $300 million unsecured term loan that matures on December 2, 2020 with the option to prepay at par anytime prior to maturity without penalty. The interest rate on the term loan is equal to LIBOR plus a ratings based margin; however, the Company entered into interest rate swaps to fix the interest rate on the entire $300 million with a weighted average interest rate of 1.824% (see note 5). The proceeds of the term loan were used to repay a $300 million Equity One term loan that came due as a result of the merger. • Assumed $300 million of senior unsecured public notes with an interest rate of 3.75% maturing in 2022. • Assumed $200 million of the senior unsecured private placement notes issued in two $100 million tranches with interest rates of 3.81% and 3.91% , respectively, maturing in 2026. • Assumed $226.3 million of fixed rate mortgage loans with interest rates ranging from 3.76% to 7.94% , and assumed a $27.8 million variable rate mortgage loan whose interest rate varies with LIBOR. The public and private unsecured notes assumed from Equity One have covenants that are similar to the Company's existing debt covenants described in Regency's latest Form 10-K.

These derivative financial instruments are all interest rate swaps, which are designated and qualify as cash flow hedges. The Company does not use derivatives for trading or speculative purposes and, as of September 30, 2017 , does not have any derivatives that are not designated as hedges. The Company has master netting agreements; however, the Company does not have multiple derivatives subject to a single master netting agreement with the same counterparties. Therefore, none are offset in the accompanying Consolidated Balance Sheets. The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in Accumulated other comprehensive income (loss) ("AOCI") and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings within Interest expense, in the accompanying Consolidated Statements of Operations. The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements: Derivatives in FASB Amount of Gain (Loss) Location and Amount of Gain Three months ended September 30, Three months ended September 30, (in thousands) 2017 2016 2017 2016 Interest rate swaps $ (39 ) 1,294 Interest expense $ (2,329 ) (43,111 ) Derivatives in FASB Amount of Gain (Loss) Location and Amount of Gain Nine months ended September 30, Nine months ended September 30, (in thousands) 2017 2016 2017 2016 Interest rate swaps $ (3,911 ) (25,338 ) Interest expense $ (8,054 ) (48,063 ) As of September 30, 2017 , the Company expects $9.1 million of net deferred losses on derivative instruments in Accumulated other comprehensive loss, including the Company's share from its Investments in real estate partnerships, to be reclassified into earnings during the next 12 months. Included in the reclassification is $8.4 million which is related to previously settled swaps on the Company's ten year fixed rate unsecured loans.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements (a) Disclosure of Fair Value of Financial Instruments All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management's estimation, reasonably approximate their fair values, except for the following: September 30, 2017 December 31, 2016 (in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial assets: Notes receivable $ 13,984 13,869 $ 10,481 10,380 Financial liabilities: Notes payable $ 2,943,986 3,027,557 $ 1,363,925 1,435,000 Unsecured credit facilities $ 578,144 580,000 $ 278,495 279,700 The above fair values represent management's estimate of the amounts that would be received from selling those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants as of September 30, 2017 and December 31, 2016 , respectively. These fair value measurements maximize the use of observable inputs. However, in situations where there is little, if any, market activity for the asset or liability at the measurement date, the fair value measurement reflects the Company's own judgments about the assumptions that market participants would use in pricing the asset or liability. The Company develops its judgments based on the best information available at the measurement date, including expected cash flows, appropriate risk-adjusted discount rates, and available observable and unobservable inputs. Service providers involved in fair value measurements are evaluated for competency and qualifications on an ongoing basis. As considerable judgment is often necessary to estimate the fair value of these financial instruments, the fair values presented above are not necessarily indicative of amounts that will be realized upon disposition of the financial instruments. The following methods and assumptions were used to estimate the fair value of these financial instruments: Notes Receivable The fair value of the Company's Notes receivable is estimated by calculating the present value of future contractual cash flows discounted at interest rates available for notes of the same terms and maturities, adjusted for counter-party specific credit risk. The fair value of Notes receivable was determined primarily using Level 3 inputs of the fair value hierarchy, which considered counter-party credit risk and collateral risk of the underlying property securing the note receivable. Notes Payable The fair value of the Company's unsecured debt is estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the unsecured debt was determined using Level 2 inputs of the fair value hierarchy. The fair value of the Company's mortgage notes payable is estimated by discounting future cash flows of each instrument at rates that reflect the current market rates available to the Company for debt of the same terms and maturities. Fixed rate loans assumed in connection with real estate acquisitions are recorded in the accompanying consolidated financial statements at fair value at the time the property is acquired. The fair value of the mortgage notes payable was determined using Level 2 inputs of the fair value hierarchy. Unsecured Credit Facilities The fair value of the Company's Unsecured credit facilities is estimated based on the interest rates currently offered to the Company by financial institutions. The fair value of the credit facilities was determined using Level 2 inputs of the fair value hierarchy. The following interest rate ranges were used by the Company to estimate the fair value of its financial instruments: September 30, 2017 December 31, 2016 Low High Low High Notes receivable 3.5% 7.4% 7.2% 7.2% Notes payable 3.1% 3.7% 2.9% 3.9% Unsecured credit facilities 1.7% 2.2% 1.5% 1.6% (b) Fair Value Measurements The following financial instruments are measured at fair value on a recurring basis: Trading Securities Held in Trust The Company has investments in marketable securities, which are assets of the non-qualified deferred compensation plan ("NQDCP"), that are classified as trading securities and included within Other assets on the accompanying Consolidated Balance Sheets. The fair value of the trading securities held in trust was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of trading securities are recorded within net investment (income) loss from deferred compensation plan in the accompanying Consolidated Statements of Operations. Available-for-Sale Securities Available-for-sale securities consist of investments in certificates of deposit and corporate bonds, and are recorded at fair value using matrix pricing methods to estimate fair value, which are considered Level 2 inputs of the fair value hierarchy. Unrealized gains or losses on these securities are recognized through Other comprehensive income. Interest Rate Derivatives The fair value of the Company's interest rate derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy. The following tables present the placement in the fair value hierarchy of assets and liabilities that are measured at fair value on a recurring basis: Fair Value Measurements as of September 30, 2017 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: Balance (Level 1) (Level 2) (Level 3) Trading securities held in trust $ 30,720 30,720 — — Available-for-sale securities 10,054 — 10,054 — Interest rate derivatives 10,201 — 10,201 — Total $ 50,975 30,720 20,255 — Liabilities: Interest rate derivatives $ (1,182 ) — (1,182 ) — Fair Value Measurements as of December 31, 2016 (in thousands) Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs Assets: Balance (Level 1) (Level 2) (Level 3) Trading securities held in trust $ 28,588 28,588 — — Available-for-sale securities 7,420 — 7,420 — Interest rate derivatives 11,622 — 11,622 — Total $ 47,630 28,588 19,042 — Liabilities: Interest rate derivatives $ (580 ) — (580 ) —

Commitments and Contingencies	Commitments and Contingencies Litigation The Company is involved in litigation on a number of matters and is subject to certain claims, which arise in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. Legal fees are expensed as incurred. After the announcement of the merger agreement with Equity One on November 14, 2016, a putative class action was filed on behalf of a purported stockholder in the Circuit Court for Duval County, Florida, under the following caption: Robert Garfield on Behalf of Himself and All Others Similarly Situated vs. Regency Centers Corporation, Martin E. Stein, Jr., John C. Schweitzer, Raymond L. Bank, Bryce Blair, C. Ronald Blankenship, J. Dix Druce, Jr., Mary Lou Fiala, David P. O'Connor, and Thomas G. Wattles, No. 16-2017-CA-000688-XXXX-MA, filed February 3, 2017. The class action alleged, among other matters, that the definitive joint proxy statement/prospectus filed by Regency and Equity One with the Securities and Exchange Commission (the “SEC”) on January 24, 2017 (the “Joint Proxy Statement/Prospectus”) omitted certain material information in connection with the merger. The complainant sought various remedies, including injunctive relief to prevent the consummation of the merger unless certain allegedly material information was disclosed and sought compensatory and rescissory damages in the event the merger was consummated without such disclosures. On February 17, 2017, the defendants entered into a stipulation of settlement with respect to the class action, pursuant to which the parties agreed, among other things, that Regency would make certain supplemental disclosures. The supplemental disclosures were made by Regency in the Current Report on Form 8-K filed by Regency with the SEC on February 17, 2017. The stipulation of settlement remains subject to court approval. Environmental The Company is also subject to numerous environmental laws and regulations as they apply to real estate pertaining to chemicals used by the dry cleaning industry, the existence of asbestos in older shopping centers, and underground petroleum storage tanks. The Company believes that the ultimate disposition of currently known environmental matters will not have a material effect on its financial position, liquidity, or operations. The Company can give no assurance that existing environmental studies with respect to the shopping centers have revealed all potential environmental contaminants or liabilities, that any previous owner, occupant or tenant did not create any material environmental condition not known to it, that the current environmental condition of the shopping centers will not be affected by tenants and occupants, by the condition of nearby properties, or by unrelated third parties, or that changes in applicable environmental laws and regulations or their interpretation will not result in additional environmental liability to the Company. Letters of Credit The Company has the right to issue letters of credit under the Line up to an amount not to exceed $50.0 million , which reduces the credit availability under the Line. These letters of credit are primarily issued as collateral on behalf of its captive insurance program and to facilitate the construction of development projects. As of September 30, 2017 and December 31, 2016 , the Company had $5.9 million and $5.8 million , respectively, in letters of credit outstanding.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Goodwill and Intangible Assets, Goodwill, Policy	Goodwill Goodwill, which is included within Other assets in the accompanying Consolidated Balance Sheets, represents the excess of the purchase price consideration for the Equity One merger over the fair value of the assets acquired and liabilities assumed, and reflects expected synergies from combining Regency's and Equity One's operations. The Company accounts for goodwill in accordance with the Intangibles - Goodwill and Other Topic of the FASB ASC, and allocates its goodwill to the reporting units, which have been determined to be at the individual property level. The Company will perform an impairment evaluation of its goodwill at least annually, in November of each year. The goodwill impairment evaluation may be completed through a qualitative or quantitative approach. Under a qualitative approach, the impairment review for goodwill consists of an assessment of whether it is more-likely-than-not that the property’s fair value is less than its carrying value. If a qualitative approach indicates it is more likely-than-not that the estimated carrying value of a property exceeds its fair value, or if the Company chooses to bypass the qualitative approach for any property, the Company will perform the quantitative approach described below. The first step of the quantitative approach consists of estimating the fair value of each property using discounted projected future cash flows and comparing those estimated fair values with the carrying values, which include the allocated goodwill. If the estimated fair value is less than the carrying value, a second step is performed to compute the amount of the impairment, if any, by determining an implied fair value of goodwill. The determination of each property’s implied fair value of goodwill requires allocation of the estimated fair value of the property to its assets and liabilities. Any unallocated fair value represents the implied fair value of goodwill which is compared to its corresponding carrying value.
New Accounting Pronouncements and Changes in Accounting Principles	Recent Accounting Pronouncements The following table provides a brief description of recent accounting pronouncements and expected impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted: ASU 2016-09, March 2016, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, an option to recognize stock compensation forfeitures as they occur, and changes to classification on the statement of cash flows. January 2017 The adoption of this standard resulted in the reclassification of income taxes withheld on share-based awards out of operating activities into financing activities on the Statement of Cash Flows. As retrospective application was required for this component of the ASU, $8.0 million was reclassified on the Statements of Cash Flows for the nine months ended September 30, 2016. ASU 2017-01 This ASU amends and provides a screen to determine when an integrated set of assets and activities, collectively referred to as a "set", is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. July 2017 This standard changed the treatment of individual operating properties from being considered a business to being considered an asset. Not yet adopted: ASU 2017-04, January 2017, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU simplifies how an entity tests goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. Instead, under this update, the Company will perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Company would then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. October 2017 The Company plans to early adopt this ASU on October 1, 2017. The adoption of this ASU will not have a material impact on the Company's financial statements and related disclosures. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2017-12, August 2017, Targeted Improvements to Accounting for Hedging Activities This ASU provides updated guidance to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require the Company 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. January 2018 The Company plans to early adopt this ASU on January 1, 2018. While the Company continues to assess all potential impacts of the standard, it currently does not expect the adoption and implementation of this standard to have a material impact on the consolidated financial statements. ASU 2016-01, January 2016, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities This ASU amends the guidance to classify equity securities with readily-determinable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Equity investments accounted for under the equity method are not included in the scope of this amendment. Early adoption of this amendment is not permitted. January 2018 The Company does not expect the adoption and implementation of this standard to have a material impact on its results of operations, financial condition or cash flows. ASU 2016-15, August 2016, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments This ASU makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Early adoption is permitted on a retrospective basis. January 2018 The ASU is consistent with the Company's current treatment and the Company does not expect the adoption and implementation of this standard to have an impact on its cash flow statement. ASU 2016-18, November 2016, Statement of Cash Flows (Topic 230): Restricted Cash This ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. The amendments in this ASU should be applied using a retrospective transition method to each period presented. January 2018 The Company expects the adoption of this ASU to result in a change to the classification and presentation of changes in restricted cash on its cash flow statement, which is not expected to be material. There should be no change to the Company's financial condition or results of operations. Standard Description Date of adoption Effect on the financial statements or other significant matters Revenue from Contracts with Customers (Topic 606) and related updates: ASU 2014-09, May 2014, Revenue from Contracts with Customers (Topic 606) ASU 2016-08, March 2016, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ASU 2016-10, April 2016, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ASU 2016-12, May 2016, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ASU 2016-19, December 2016, Technical Corrections and Improvements ASU 2016-20, December 2016, Technical Corrections and Improvements to Topic 606 Revenue from Contracts With Customers ASU 2017-05, February 2017, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (Subtopic 610-20) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("Topic 606"). The objective of Topic 606 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. It will supersede most of the existing revenue guidance, including industry-specific guidance. The core principal of this new standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying Topic 606, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. Topic 606 applies to all contracts with customers except those that are within the scope of other topics in the FASB's accounting standards codification. As a result, Topic 606 does not apply to revenue from lease contracts until the adoption of the new leases standard, Topic 842, in January 2019. ASU 2017-05 clarifies that ASC 610-20 applies to all nonfinancial assets (including real estate) for which the counterparty is not a customer and requires an entity to derecognize a nonfinancial asset in a partial sale transaction when it ceases to have a controlling financial interest in the asset and has transferred control of the asset. Once an entity transfers control of the nonfinancial asset, the entity is required to measure any noncontrolling interest it receives or retains at fair value. Under the current guidance, a partial sale is recognized and carryover basis is used for the retained interest resulting in only partial gain recognition by the entity, however, the new guidance eliminates the use of carryover basis and generally requires the full gain be recognized. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most recent period presented in the financial statements. January 2018 The majority of the Company's revenue originates from lease contracts and will be subject to Topic 842 to be adopted in January 2019. Upon the adoption of the new leases standard, certain recoveries from tenants may become subject to the revenue standard, which may have a different recognition pattern or presentation than under current GAAP. Beyond revenue from lease contracts, the Company's other main revenue streams, include: - Management, transaction and other fees from the Company's real estate partnerships, primarily in the form of property management fees, asset management fees, and leasing commission fees. The Company evaluated all partnership fee relationships and does not currently expect any changes in the timing of revenue recognition from these revenue streams. - Sales of real estate assets will be accounted for under Subtopic 610-20, which provides for revenue recognition based on transfer of control. For property sales where Regency has no continuing involvement, there should be no change to the Company's timing of recognition. For property sales in which Regency has continuing involvement, full gain recognition may be required, where gains may have been deferred under existing GAAP. Upon adoption of ASU 2017-05, some of the Company's $33 million of previously deferred gains from property sales to entities in which Regency had continuing involvement will remain deferred and be recognized in the future, while some will be recognized through opening retained earnings. The Company is still analyzing the disclosure requirements and intends to follow the modified retrospective method of adoption, applying the standard to only 2018, and not restating prior periods presented in future financial statements. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2016-02, February 2016, Leases (Topic 842) This ASU amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. It also makes targeted changes to lessor accounting, including a change to the treatment of internal leasing costs and legal costs, which can no longer be capitalized. Early adoption of this standard is permitted to coincide with adoption of ASU 2014-09. The 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. January 2019 The Company is evaluating the impact this standard will have on its financial statements and related disclosures. Upon adoption, the Company will recognize right of use assets and corresponding lease obligations for its office and ground leases. Capitalization of internal leasing costs and legal costs will no longer be permitted upon the adoption of this standard, which will result in an increase in Total operating expenses in the Consolidated Statements of Operations in the period of adoption and prospectively. Historic capitalization of internal leasing costs was $7.5 million and $10.5 million during the nine months ended September 30, 2017 and the year ended December 31, 2016, respectively. Historic capitalization of legal costs was $0.9 million and $0.7 million during the nine months ended September 30, 2017 and the year ended December 31, 2016, respectively, including our pro rata share recognized through Equity in income of investments in real estate partnerships. ASU 2016-13, June 2016 , Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU also applies to how the Company determines its allowance for doubtful accounts on tenant receivables. January 2020 The Company is evaluating the alternative methods of adoption and the impact it will have on its financial statements and related disclosures.
Consolidation, Variable Interest Entity, Policy	Real Estate Partnerships As of September 30, 2017 , Regency has an ownership interest in 125 properties through partnerships, of which 11 are consolidated. Our partners in these ventures include institutional investors, other real estate developers and/or operators, and individual parties who help Regency source transactions for development and investment (the "Partners" or "limited partners"). Regency has a variable interest in these entities through its equity interests. As managing member, Regency maintains the books and records and typically provides leasing and property management to the partnerships. The partners’ level of involvement varies from protective decisions (debt, bankruptcy, selling primary asset(s) of business) to involvement in approving leases, operating budgets, and capital budgets. • Those partnerships for which the Partners only have protective rights are considered VIEs under ASC 810, Consolidation. Regency is the primary beneficiary of these VIEs as Regency has power over these partnerships and they operate primarily for the benefit of Regency. As such, Regency consolidates these entities and reports the limited partners’ interest as noncontrolling interests. The operations of the VIEs are funded with cash flows generated by the properties, or in the case of developments, with capital contributions or third party construction loans. Regency does not provide financial support to the VIEs beyond the terms stipulated in the partnership operating agreements. • Those partnerships for which the partners are involved in the day to day decisions and do not have any other aspects that would cause them to be considered VIEs, are evaluated for consolidation using the voting interest model. ◦ Those partnerships in which Regency has a controlling financial interest are consolidated and the limited partners’ ownership interest and share of net income is recorded as noncontrolling interest. ◦ Those partnerships in which Regency does not have a controlling financial interest are accounted for using the equity method, and its ownership interest is recognized through single-line presentation as Investments in real estate partnerships in the Consolidated Balance Sheet, and Equity in income of investments in real estate partnerships in the Consolidated Statements of Operations. Cash distributions of earnings from operations of investments in real estate partnerships are presented in cash flows provided by operating activities in the accompanying Consolidated Statements of Cash Flows. Cash distributions from the sale of a property or loan proceeds received from the placement of debt on a property included in investments in real estate partnerships are presented in cash flows provided by investing activities in the accompanying Consolidated Statements of Cash Flows. The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is either (1) accreted to income and recorded in Equity in income of investments in real estate partnerships in the accompanying Consolidated Statements of Operations over the expected useful lives of the properties and other intangible assets, which range in lives from 10 to 40 years, or (2) recognized upon sale of the underlying asset(s) or settlement of underlying liabilities, or (3) recognized at liquidation if the joint venture agreement includes a unilateral right to elect to dissolve the real estate partnership and, upon such an election, receive a distribution in-kind. The assets of the partnerships are restricted to the use of the partnerships and cannot be used as security by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of the partnerships.
Consolidation, Policy	Consolidation The Company consolidates properties that are wholly owned and properties where it owns less than 100%, but which it controls. Control is determined using an evaluation based on accounting standards related to the consolidation of voting interest entities and variable interest entities ("VIEs"). For joint ventures that are determined to be a VIE, the Company consolidates the entity where it is deemed to be the primary beneficiary. Determination of the primary beneficiary is based on whether an entity has (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance, and (2) the obligation to absorb losses of the entity that could potentially be significant to the VIE or the right to receive benefits from the entity that could potentially be significant to the VIE. The Company's determination of the primary beneficiary considers all relationships between it and the VIE, including management agreements and other contractual arrangements. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2017 , the Parent Company owned approximately 99.8% of the outstanding common Partnership Units of the Operating Partnership with the remaining limited Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities of the Operating Partnership. As such, the Operating Partnership is considered a VIE, and the Parent Company, which consolidates it, is the primary beneficiary. The Parent Company’s only investment is the Operating Partnership. Net income and distributions of the Operating Partnership are allocable to the general and limited common Partnership Units in accordance with their ownership percentages.

Accounting Changes and Error Corrections [Abstract]
Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]	Recent Accounting Pronouncements The following table provides a brief description of recent accounting pronouncements and expected impact on our financial statements: Standard Description Date of adoption Effect on the financial statements or other significant matters Recently adopted: ASU 2016-09, March 2016, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, an option to recognize stock compensation forfeitures as they occur, and changes to classification on the statement of cash flows. January 2017 The adoption of this standard resulted in the reclassification of income taxes withheld on share-based awards out of operating activities into financing activities on the Statement of Cash Flows. As retrospective application was required for this component of the ASU, $8.0 million was reclassified on the Statements of Cash Flows for the nine months ended September 30, 2016. ASU 2017-01 This ASU amends and provides a screen to determine when an integrated set of assets and activities, collectively referred to as a "set", is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. July 2017 This standard changed the treatment of individual operating properties from being considered a business to being considered an asset. Not yet adopted: ASU 2017-04, January 2017, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU simplifies how an entity tests goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit's goodwill with the carrying amount of that goodwill. Instead, under this update, the Company will perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Company would then recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to that reporting unit. October 2017 The Company plans to early adopt this ASU on October 1, 2017. The adoption of this ASU will not have a material impact on the Company's financial statements and related disclosures. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2017-12, August 2017, Targeted Improvements to Accounting for Hedging Activities This ASU provides updated guidance to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require the Company 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. January 2018 The Company plans to early adopt this ASU on January 1, 2018. While the Company continues to assess all potential impacts of the standard, it currently does not expect the adoption and implementation of this standard to have a material impact on the consolidated financial statements. ASU 2016-01, January 2016, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities This ASU amends the guidance to classify equity securities with readily-determinable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Equity investments accounted for under the equity method are not included in the scope of this amendment. Early adoption of this amendment is not permitted. January 2018 The Company does not expect the adoption and implementation of this standard to have a material impact on its results of operations, financial condition or cash flows. ASU 2016-15, August 2016, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments This ASU makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Early adoption is permitted on a retrospective basis. January 2018 The ASU is consistent with the Company's current treatment and the Company does not expect the adoption and implementation of this standard to have an impact on its cash flow statement. ASU 2016-18, November 2016, Statement of Cash Flows (Topic 230): Restricted Cash This ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. The amendments in this ASU should be applied using a retrospective transition method to each period presented. January 2018 The Company expects the adoption of this ASU to result in a change to the classification and presentation of changes in restricted cash on its cash flow statement, which is not expected to be material. There should be no change to the Company's financial condition or results of operations. Standard Description Date of adoption Effect on the financial statements or other significant matters Revenue from Contracts with Customers (Topic 606) and related updates: ASU 2014-09, May 2014, Revenue from Contracts with Customers (Topic 606) ASU 2016-08, March 2016, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations ASU 2016-10, April 2016, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing ASU 2016-12, May 2016, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients ASU 2016-19, December 2016, Technical Corrections and Improvements ASU 2016-20, December 2016, Technical Corrections and Improvements to Topic 606 Revenue from Contracts With Customers ASU 2017-05, February 2017, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (Subtopic 610-20) In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers ("Topic 606"). The objective of Topic 606 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. It will supersede most of the existing revenue guidance, including industry-specific guidance. The core principal of this new standard is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying Topic 606, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. Topic 606 applies to all contracts with customers except those that are within the scope of other topics in the FASB's accounting standards codification. As a result, Topic 606 does not apply to revenue from lease contracts until the adoption of the new leases standard, Topic 842, in January 2019. ASU 2017-05 clarifies that ASC 610-20 applies to all nonfinancial assets (including real estate) for which the counterparty is not a customer and requires an entity to derecognize a nonfinancial asset in a partial sale transaction when it ceases to have a controlling financial interest in the asset and has transferred control of the asset. Once an entity transfers control of the nonfinancial asset, the entity is required to measure any noncontrolling interest it receives or retains at fair value. Under the current guidance, a partial sale is recognized and carryover basis is used for the retained interest resulting in only partial gain recognition by the entity, however, the new guidance eliminates the use of carryover basis and generally requires the full gain be recognized. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most recent period presented in the financial statements. January 2018 The majority of the Company's revenue originates from lease contracts and will be subject to Topic 842 to be adopted in January 2019. Upon the adoption of the new leases standard, certain recoveries from tenants may become subject to the revenue standard, which may have a different recognition pattern or presentation than under current GAAP. Beyond revenue from lease contracts, the Company's other main revenue streams, include: - Management, transaction and other fees from the Company's real estate partnerships, primarily in the form of property management fees, asset management fees, and leasing commission fees. The Company evaluated all partnership fee relationships and does not currently expect any changes in the timing of revenue recognition from these revenue streams. - Sales of real estate assets will be accounted for under Subtopic 610-20, which provides for revenue recognition based on transfer of control. For property sales where Regency has no continuing involvement, there should be no change to the Company's timing of recognition. For property sales in which Regency has continuing involvement, full gain recognition may be required, where gains may have been deferred under existing GAAP. Upon adoption of ASU 2017-05, some of the Company's $33 million of previously deferred gains from property sales to entities in which Regency had continuing involvement will remain deferred and be recognized in the future, while some will be recognized through opening retained earnings. The Company is still analyzing the disclosure requirements and intends to follow the modified retrospective method of adoption, applying the standard to only 2018, and not restating prior periods presented in future financial statements. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2016-02, February 2016, Leases (Topic 842) This ASU amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets. It also makes targeted changes to lessor accounting, including a change to the treatment of internal leasing costs and legal costs, which can no longer be capitalized. Early adoption of this standard is permitted to coincide with adoption of ASU 2014-09. The 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. January 2019 The Company is evaluating the impact this standard will have on its financial statements and related disclosures. Upon adoption, the Company will recognize right of use assets and corresponding lease obligations for its office and ground leases. Capitalization of internal leasing costs and legal costs will no longer be permitted upon the adoption of this standard, which will result in an increase in Total operating expenses in the Consolidated Statements of Operations in the period of adoption and prospectively.

Historic capitalization of legal costs was $0.9 million and $0.7 million during the nine months ended September 30, 2017 and the year ended December 31, 2016, respectively, including our pro rata share recognized through Equity in income of investments in real estate partnerships. ASU 2016-13, June 2016 , Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This ASU replaces the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.
