Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Significant Accounting Policies	1. 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 primarily engages in the ownership, management, leasing, acquisition, and development and redevelopment of shopping centers through the Operating Partnership, and has no other assets other than through its investment in the Operating Partnership, and its only liabilities are $200 million of unsecured private placement notes, which are co-issued and guaranteed by the Operating Partnership. The Parent Company guarantees all of the unsecured debt of the Operating Partnership. As of September 30, 2020, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owned 299 properties and held partial interests in an additional 115 properties 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, except for the goodwill impairment, discussed in Note 4, resulting from the market and economic impacts of the COVID-19 pandemic. COVID-19 Pandemic On March 11, 2020, the novel coronavirus disease (“COVID-19”) was declared a pandemic (“COVID-19 pandemic”) by the World Health Organization as the disease spread throughout the world. During the ongoing COVID-19 pandemic, U.S. federal, state, and local governments have continued to mandate various actions to reduce or prevent the spread of COVID-19, which continues to directly impact many of the Company’s tenants whose businesses may be considered non-essential. While essential businesses, such as grocery stores that anchor over 80% of the Company’s operating centers, have thus far been able to continue to operate and serve their customers, non-essential businesses continue to experience significant declines in customer traffic, when compared to previous years, or have temporarily closed their stores in reaction to legally enforceable governmental orders or overall efforts to support social distancing. As a result, many retailers have had to evaluate alternative means of providing their goods and services to their customers or, in the case of many non-essential tenants, to close. The COVID-19 pandemic continues to evolve, making the broader implications on the Company’s future results of operations and overall financial performance uncertain at this time. While much of the Company’s lease income is derived from contractual rent payments, the tenants’ ability to meet their lease obligations have been negatively impacted by the disruptions and uncertainties of the COVID-19 pandemic. The tenants’ ability to respond to these disruptions, including changes in their customers’ shopping habits and behaviors, will influence the tenants’ ability to survive and ultimately fulfill their lease obligations. Although many of the Company’s tenants have reported initially improved sales results upon reopening, the risk of diminished sales and future closures exists as the virus remains active and continues to spread which could result in a resurgence in COVID-19 cases and reinstituted government mandated closures. Due to the COVID-19 pandemic, certain tenants have requested rent concessions or have sought to renegotiate future rents based on changes to the economic environment. Other tenants have chosen not to reopen or honor the terms of their existing lease agreements. The Company is closely monitoring its cash collections from tenants which, for many businesses classified as non-essential, have significantly declined since the start of the COVID-19 pandemic and resulting restrictions. Approximately 86% of pro-rata base rent billed for the three months ended September 30, 2020, has been collected through October 31, 2020. Since the COVID-19 pandemic began, the Company has executed approximately 1,300 rent deferral agreements within its consolidated real estate portfolio and its unconsolidated real estate investment partnerships. This deferred rent represents, on a weighted average basis, deferral periods of approximately 3 months, with repayment periods of approximately 9.2 months beginning in December 2020. The Company expects to continue to work with other tenants, which may result in further rent deferrals, concessions or abatements. As a result, there can be no assurance that cash flows from operations will be sufficient to fund the Company’s dividend payments without the benefit of other sources of capital or changes to its current dividend policy. New leasing activity has declined and is expected to remain at lower levels into 2021 as businesses delay executing leases amidst the immediate and uncertain future economic impacts of the COVID-19 pandemic. This, coupled with tenant failures, may result in decreased demand for space in our centers, which could result in pricing pressure on rents. Additionally, with delays in construction for tenant improvements due to the impacts of the pandemic, it may take longer before new tenants are able to open and commence rent payments. T he Company’s ability to successfully start or complete tenant buildouts, new ground up development , or redevelopment of existing properties w as adversely impacted by governmental orders shutting down construction activities . The Company also experienced i mpacts on its ability to source materials for construction and labor shortages impacting its ability to complete construction projects on anticipated schedules. In the event a surge in new cases resulting in additional lockdowns occurs, s imilar impact s to the Company’s supply chain may arise which could have a material adverse effect on the Company’s business, financial condition and results of operation . The Company continue s to closely monitor and assess the capital requirements of all in process and planned developments, redevelopme nts, and capital expenditures. The Company is carefully proceeding in a targeted manner on a project-by-project basis which has resulted in delaying, phasing or curtailing certain in-process and planned development, redevelopment and capital expenditure projects . O n March 30, 2020, the Company withdrew its fiscal 2020 guidance previously provided. The duration and severity of the health crisis in the United States and the speed at which the country, states and localities are able to safely reopen and remain open, will continue to materially impact the overall economy, retail tenants, and therefore the Company’s results of operations As such, the impact from the COVID-19 pandemic may not be fully reflected in the Company’s results of operations and overall financial position until future periods and could result in a further materially adverse impact to the Company’s financial condition and results of operations The Company has long had a business continuity and disaster recovery plan which has been successfully implemented in the past. This experience enabled the Company to continue operating productively during the COVID-19 pandemic while its employees work safely from home, as roles permit, during the early stages of the COVID-19 pandemic. The Company has maintained, and expects to continue to maintain, its financial reporting systems as well as its internal controls over financial reporting and disclosure controls and procedures. The Company has since developed and executed its office reopening plan allowing employees, in the current stage, the option to work from home or the office. The Company has implemented CDC recommended protocols and developed detailed plans to prioritize the well-being of its employees, and encourages its tenants to similarly follow all rules and guidelines. All Company employees are required to complete training before returning to the office. Consolidation The Company consolidates properties that are wholly-owned and properties where it owns less than 100%, but which it has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2020, the Parent Company owned approximately 99.6% of the outstanding common Partnership Units of the Operating Partnership, with the remaining limited common Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or other assets. The Parent Company has evaluated the conditions as specified under Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity Real Estate Partnerships As of September 30, 2020, Regency had a partial ownership interest in 125 properties through partnerships, of which 10 are consolidated. Regency's partners include institutional investors and other real estate developers and/or operators (the “Partners” or “limited partners”). Regency has a variable interest in these entities through its equity interests, with Regency the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships for which it is the primary beneficiary and reports the limited partners’ interests as Noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be used by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners . The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) September 30, 2020 December 31, 2019 Assets Net real estate investments (1) $ 129,881 325,464 Cash, cash equivalents and restricted cash (1) 5,456 57,269 Liabilities Notes payable 7,329 17,740 Equity Limited partners’ interests in consolidated partnerships 28,827 30,655 (1) Included in the December 31, 2019, balances were real estate assets and cash held in Section 1031 like-kind exchanges, of which none remained at September 30, 2020. Revenues and Other Receivables Other property income includes incidental income from the properties and is generally recognized at the point in time that the performance obligation is met. All income from contracts with the Company's real estate partnerships is included within Management, transaction and other fees on the Consolidated Statements of Operations. The primary components of these revenue streams, the timing of satisfying the performance obligations, and amounts recognized are as follows: Three months ended September 30, Nine months ended September 30, (in thousands) Timing of satisfaction of performance obligations 2020 2019 2020 2019 Other property income Point in time $ 2,261 2,780 $ 7,001 6,956 Management, transaction and other fees: Property management services Over time 3,598 3,648 10,830 11,076 Asset management services Over time 1,657 1,803 5,250 5,341 Leasing services Point in time 708 1,239 1,948 2,702 Other transaction fees Point in time 179 663 1,056 2,649 Total management, transaction, and other fees $ 6,142 7,353 $ 19,084 21,768 The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $9.8 million and $11.6 million, as of September 30, 2020 and December 31, 2019, respectively. 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: Accounting Standards Update (“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 applies to how the Company evaluates impairments of any available-for-sale debt securities and any non-operating lease receivables, including lease receivables arising from leases classified as sales-type or direct finance leases. January 2020 The Company has completed its evaluation and adoption of this standard, which resulted in changes in evaluating impairment of its available-for-sale debt securities. Declines in fair value below amortized cost resulting from credit related factors will be reflected in earnings, within Net investment income in the accompanying Consolidated Statements of Operations. Changes in value from market related factors continue to be recognized in Other comprehensive income (“OCI”). The Company’s investments in available-for-sale debt securities are invested in investment grade quality holdings or U.S. government backed securities, and are well diversified. During the nine months ended September 30, 2020, the Company did not recognize any allowance for credit loss. Additionally, the Company’s non-operating lease receivables experienced no credit losses during the nine months ended September 30, 2020, and the Company has no other financial instruments, such as lease receivables arising from sales-type or direct finance leases, subject to this ASU. ASU 2018-19, November 2018, Codification Improvements to Topic 326, Financial Instruments - Credit Losses This ASU clarifies that receivables arising from operating leases are not within the scope of Subtopic 326-20. Instead, impairment of receivables arising from operating leases should be accounted for in accordance with Topic 842, Leases January 2020 The Company has completed its evaluation and adoption of this standard with no additional changes in its accounting for operating leases and related receivables. ASU 2018-13, August 2018, Fair Value Measurements (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement This ASU modifies the disclosure requirements for fair value measurements within the scope of Topic 820, Fair Value Measurements January 2020 The Company has completed its evaluation and adoption of this new standard. The Company does not have any assets or liabilities measured to fair value requiring modified disclosures at September 30, 2020. Standard Description Date of adoption Effect on the financial statements or other significant matters ASU 2018-15, August 2018, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The amendments in this ASU align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The ASU provides further clarification of the appropriate presentation of capitalized costs, the period over which to recognize the expense, the presentation within the Statements of Operations and Statements of Cash Flows, and disclosure requirements. January 2020 The Company has completed its evaluation and adoption of this standard. Qualifying implementation costs incurred in a cloud computing arrangement that is a service contract are no longer expensed as incurred but rather are deferred within Other assets and amortized to earnings, within General and administrative expense in the accompanying Consolidated Statements of Operations, over the term of the arrangement. Cash flows attributable to the service arrangements, including implementation thereof, are reflected as Operating cash flows within the Consolidated Statements of Cash Flows. ASU 2020-04 , Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU 2020-04, Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives, and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. March 2020 through December 31, 2022 The Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. As additional index changes in the market occur, the Company will evaluate the impact of the guidance and may apply other elections as applicable. Not yet adopted: ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740, Income Taxes Notable changes of potential impact include income-based franchise taxes and interim period recognition of enacted changes in tax laws or rates. January 2021 The Company is evaluating this update and does not expect it to have a material impact to its financial condition, results of operations, cash flows or related footnote disclosures.

A decision to sell a reporting unit results in the need to evaluate its goodwill for recoverability and may result in impairment. Additionally, other changes impacting a reporting unit may be considered a triggering event. If events occur that trigger an impairment evaluation at multiple reporting units, a goodwill impairment may be significant. During the three months ended March 31, 2020, the Company recognized $132.2 million of Goodwill impairment. The market disruptions related to the significant economic impacts of the COVID-19 pandemic triggered evaluation of reporting unit fair values for goodwill impairment. The Company’s reporting units are at the individual property level. The carrying value of long-lived assets of the reporting units were first tested for recoverability with no resulting impairments. Next, the fair value of each reporting unit was compared to its carrying value, including goodwill. Of the 269 reporting units with goodwill, 87 of those were determined to have fair values lower than carrying value. As such, goodwill impairment losses totaling $132.2 million were recognized for the amount that the carrying amount of the reporting unit, including goodwill, exceeded its fair value, limited to the total amount of goodwill allocated to that reporting unit. Fair values of the reporting units were determined using a discounted cash flow approach, including current market cash flow assumptions for impacts to existing tenant contractual rent as well as prospective future rent and occupancy changes and related capital and operating expenditures. The cap rates and discount rates used in the analysis reflect management’s best estimate of market rates adjusted for the current environment. No additional Goodwill impairments were recognized after March 31, 2020.

(2) Weighted average effective rate for the Line is calculated based on a fully drawn Line balance. Significant financing activity during 2020 includes: • On May 11, 2020, the Company issued $600 million of 3.70% senior unsecured public notes, which priced at 99.805%, and mature on June 15, 2030.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	6. Derivative Financial Instruments The Company may use derivative financial instruments, including interest rate swaps, caps, options, floors, and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with its borrowings. The principal objective of such arrangements is to minimize the risks and/or costs associated with the Company’s operating and financial structure as well as to hedge specific anticipated transactions. The Company does not intend to utilize derivatives for speculative or other purposes other than interest rate risk management. The use of derivative financial instruments carries certain risks, including the risk that the counterparties to these contractual arrangements are not able to perform under the agreements. To mitigate this risk, the Company only enters into derivative financial instruments with counterparties with high credit ratings and with major financial institutions with which the Company and its affiliates may also have other financial relationships. The Company does not anticipate that any of the counterparties will fail to meet their obligations. The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The following table summarizes the terms and fair values of the Company's derivative financial instruments, as well as their classification on the Consolidated Balance Sheets: Fair Value (in thousands) Assets (Liabilities) (1) Effective Date Maturity Date Notional Amount Receive Variable Rate of Pay Fixed Rate of September 30, 2020 December 31, 2019 8/1/16 1/5/22 $ 265,000 1 Month LIBOR with Floor 1.053% $ (2,999 ) 2,674 4/7/16 4/1/23 19,497 1 Month LIBOR 1.303% (553 ) 148 12/1/16 11/1/23 32,517 1 Month LIBOR 1.490% (1,300 ) 84 9/17/19 3/17/25 24,000 1 Month LIBOR 1.542% (1,411 ) 81 6/2/17 6/2/27 36,736 1 Month LIBOR with Floor 2.366% (4,154 ) (1,515 ) $ (10,417 ) 1,472 (1) Derivatives in an asset position are included within Other assets in the accompanying Consolidated Balance Sheets, while those in a liability position are included within Accounts payable and other liabilities. 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, 2020, does not have any derivatives that are not designated as hedges. The changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in Accumulated Other Comprehensive Loss (“AOCI”) and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements: Location and Amount of Gain (Loss) Recognized in OCI on Derivative Location and Amount of Gain (Loss) Reclassified from AOCI into Income Total amounts presented in the Consolidated Statements of Operations in which the effects of cash flow hedges are recorded Three months ended September 30, Three months ended September 30, Three months ended September 30, (in thousands) 2020 2019 2020 2019 2020 2019 Interest rate swaps $ (666 ) (3,851 ) Interest expense $ 2,570 1,677 Interest expense, net $ 40,794 38,253 Nine months ended September 30, Nine months ended September 30, Nine months ended September 30, (in thousands) 2020 2019 2020 2019 2020 2019 Interest rate swaps $ (19,187 ) (18,567 ) Interest expense $ 6,479 2,085 Interest expense, net $ 118,605 113,178 As of September 30, 2020, the Company expects approximately $6.1 million of accumulated comprehensive losses on derivative instruments in AOCI, including the Company's share from its Investments in real estate partnerships, to be reclassified into earnings during the next 12 months.

Leases

Leases [Abstract]
Lessor, Operating Leases	7. Leases All of the Company’s leases are classified as operating leases. The Company's Lease income is comprised of both fixed and variable income. Fixed and in-substance fixed lease income includes stated amounts per the lease contract, which are primarily related to base rent, and in some cases stated amounts for common area maintenance (“CAM”), real estate taxes, and insurance. Income for these amounts is recognized on a straight-line basis. Variable lease income includes the following two main items in the lease contracts: (i) Recoveries from tenants represents amounts tenants are contractually obligated to reimburse the Company for the tenants’ portion of actual Recoverable Costs incurred. Generally the Company’s leases provide for the tenants to reimburse the Company based on the tenants’ share of the actual costs incurred in proportion to the tenants’ share of leased space in the property. (ii) Percentage rent represents amounts billable to tenants based on the tenants' actual sales volume in excess of levels specified in the lease contract. The following table provides a disaggregation of lease income recognized as either fixed or variable lease income based on the criteria specified in ASC Topic 842: (in thousands) Three months ended September 30, Nine months ended September 30, 2020 2019 2020 2019 Operating lease income Fixed and in-substance fixed lease income $ 200,020 204,686 $ 607,429 607,758 Variable lease income 60,535 59,872 186,952 185,317 Other lease related income, net: Above/below market rent and tenant rent inducement amortization, net 7,811 11,086 31,107 31,334 Uncollectible straight line rent (7,678 ) (1,279 ) (27,867 ) (5,060 ) Uncollectible amounts billable in lease income (26,147 ) (2,222 ) (65,991 ) (3,667 ) Total lease income $ 234,541 272,143 $ 731,630 815,682 Lease income for operating leases with fixed payment terms is recognized on a straight-line basis over the expected term of the lease for all leases for which collectibility is considered probable at the commencement date. At lease commencement, the Company generally expects that collectibility is probable due to the Company’s credit checks on tenants and other creditworthiness analysis undertaken before entering into a new lease; therefore, income from most operating leases is initially recognized on a straight-line basis. For operating leases in which collectibility of Lease income is not considered probable, Lease income is recognized on a cash basis and all previously recognized straight-line rent receivables are reversed in the period in which the Lease income is determined not to be probable of collection. In addition to the lease-specific collectibility assessment performed under Topic 842, the Company also recognizes a general reserve, as a reduction to Lease income, for its portfolio of operating lease receivables which are not expected to be fully collectible based on the Company’s historical collection experience. During the nine months ended September 30, 2020, the Company experienced a significantly higher rate of uncollectible lease income driven by changes in expectations of collectibility of both past due rents and recoveries and future rent steps given the impact of the COVID-19 pandemic on our tenants. Additionally, certain tenants experiencing economic difficulties during this pandemic have sought rent concessions, which in some cases the Company has granted, to date, primarily in the form of rent deferrals. In April 2020, the FASB issued interpretive guidance relating to the accounting for lease concessions provided as a result of COVID-19. In this guidance, entities can elect not to apply lease modification accounting with respect to such lease concessions, and instead, treat the concession as if it was a part of the existing contract. This guidance is only applicable to COVID-19 related lease concessions that do not result in a substantial increase in the right of the lessor or the obligations of the lessee. The Company has elected to treat concessions that satisfy this criteria as though the concession was part of the existing contract and therefore not treated like a lease modification. Beginning during the second quarter of 2020, the Company has executed approximately 1,300 rent deferral agreements representing $30.6 million of rent or 3.5% of annual base rent, within its consolidated real estate portfolio and our unconsolidated real estate investment partnerships . This deferred rent represent s , on a weighted average basis, deferral period s of approximately 3 months , with repayment periods of approximately 9.2 months beginning in December 2020 .

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. 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, 2020 December 31, 2019 (in thousands) Carrying Amount Fair Value Carrying Amount Fair Value Financial liabilities: Notes payable $ 3,723,923 4,072,114 3,435,161 3,688,604 Unsecured credit facilities $ 264,605 264,075 484,383 489,496 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, 2020 and December 31, 2019, 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. (b) Fair Value Measurements The following financial instruments are measured at fair value on a recurring basis: Securities The Company has investments in marketable securities that are included within Other assets on the accompanying Consolidated Balance Sheets. The fair value of the securities was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of securities are recorded within Net investment (income) loss in the accompanying Consolidated Statements of Operations, and include unrealized gains of $1.3 million and unrealized losses of $15,000 during the three months ended September 30, 2020 and 2019, respectively, and unrealized gains of $251,000 and $2.7 million for the nine months ended September 30, 2020 and 2019, respectively. Available-for-Sale Debt Securities Available-for-sale debt 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 debt 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, 2020 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 40,849 40,849 — — Available-for-sale debt securities 11,146 — 11,146 — Interest rate derivatives — — — — Total $ 51,995 40,849 11,146 — Liabilities: Interest rate derivatives $ (10,417 ) — (10,417 ) — Fair Value Measurements as of December 31, 2019 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Unobservable Inputs (in thousands) Balance (Level 1) (Level 2) (Level 3) Assets: Securities $ 39,599 39,599 — — Available-for-sale debt securities 10,755 — 10,755 — Interest rate derivatives 2,987 — 2,987 — Total $ 53,341 39,599 13,742 — Liabilities: Interest rate derivatives $ (1,515 ) — (1,515 ) — There were no assets measured at fair value on a nonrecurring basis as of September 30, 2020 .

At settlement, the Company issued 1,894,845 shares of its common stock, receiving $125.8 million of net proceeds which were used for working capital and general corporate purposes. Share Repurchase Program On February 4, 2020, the Company's Board authorized a common share repurchase program under which the Company may purchase, from time to time, up to a maximum of $250 million shares of its outstanding common stock through open market purchases or in privately negotiated transactions. Any shares purchased, if not retired, will be treated as treasury shares. The program is set to expire on February 5, 2021, but may be modified or terminated at the discretion of the Board. The timing and actual number of shares purchased under the program depend upon marketplace conditions, liquidity needs, and other factors. Through September 30, 2020, no shares have been repurchased under this program. Common Units of the Operating Partnership Common units of the operating partnership are issued or redeemed and retired for each of the shares of Parent Company common stock issued or repurchased and retired, as described above. In January 2020, the Operating Partnership issued 18,613 exchangeable operating partnership units, valued at $1.3 million, as partial purchase price consideration for the acquisition of an additional 16.62% interest in an operating shopping center.

Commitments and Contingencies	13. 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. However, no assurances can be given as to the outcome of any threatened or pending legal proceedings. Legal fees are expensed as incurred. Environmental The Company is subject to numerous environmental laws and regulations pertaining primarily to chemicals historically used by certain current and former dry cleaning tenants, the existence of asbestos in older shopping centers, and older 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 its shopping centers have revealed all potential environmental contaminants; that its estimate of liabilities will not change as more information becomes available; that any previous owner, occupant or tenant did not create any material environmental condition not known to the Company; 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; and 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, 2020 and December 31, 2019, the Company had $9.8 million and $12.5 million, respectively, in letters of credit outstanding.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Consolidation	Consolidation The Company consolidates properties that are wholly-owned and properties where it owns less than 100%, but which it has control over the activities most important to the overall success of the partnership. Control is determined using an evaluation based on accounting standards related to the consolidation of Variable Interest Entities ("VIEs") and voting interest entities. Ownership of the Operating Partnership The Operating Partnership’s capital includes general and limited common Partnership Units. As of September 30, 2020, the Parent Company owned approximately 99.6% of the outstanding common Partnership Units of the Operating Partnership, with the remaining limited common Partnership Units held by third parties (“Exchangeable operating partnership units” or “EOP units”). Each EOP unit is exchangeable for cash or one share of common stock of the Parent Company, at the discretion of the Parent Company, and the unit holder cannot require redemption in cash or other assets. The Parent Company has evaluated the conditions as specified under Accounting Standards Codification (“ASC”) Topic 480, Distinguishing Liabilities from Equity
Real Estate Partnerships	Real Estate Partnerships As of September 30, 2020, Regency had a partial ownership interest in 125 properties through partnerships, of which 10 are consolidated. Regency's partners include institutional investors and other real estate developers and/or operators (the “Partners” or “limited partners”). Regency has a variable interest in these entities through its equity interests, with Regency the primary beneficiary in certain of these real estate partnerships. As such, Regency consolidates the partnerships for which it is the primary beneficiary and reports the limited partners’ interests as Noncontrolling interests. For those partnerships which Regency is not the primary beneficiary and does not control, but has significant influence, Regency recognizes its investment in them using the equity method of accounting. The assets of these partnerships are restricted to the use of the partnerships and cannot be used by general creditors of the Company. And similarly, the obligations of the partnerships can only be settled by the assets of these partnerships or additional contributions by the partners . The major classes of assets, liabilities, and non-controlling equity interests held by the Company's consolidated VIEs, exclusive of the Operating Partnership, are as follows: (in thousands) September 30, 2020 December 31, 2019 Assets Net real estate investments (1) $ 129,881 325,464 Cash, cash equivalents and restricted cash (1) 5,456 57,269 Liabilities Notes payable 7,329 17,740 Equity Limited partners’ interests in consolidated partnerships 28,827 30,655

A decision to sell a reporting unit results in the need to evaluate its goodwill for recoverability and may result in impairment. Additionally, other changes impacting a reporting unit may be considered a triggering event. If events occur that trigger an impairment evaluation at multiple reporting units, a goodwill impairment may be significant.
