EXPLANATORY NOTE

This report combines the quarterly reports on Form 10-Q for the quarter ended March 31, 2018, of Regency Centers Corporation and Regency Centers, L.P. Unless stated otherwise or the context otherwise requires, references to “Regency Centers Corporation” or the “Parent Company” mean Regency Centers Corporation and its controlled subsidiaries; and references to “Regency Centers, L.P.” or the “Operating Partnership” mean Regency Centers, L.P. and its controlled subsidiaries. The term “the Company”,"Regency Centers" or “Regency” means the Parent Company and the Operating Partnership, collectively.

The Parent Company is a real estate investment trust (“REIT”) and the general partner of the Operating Partnership. The Operating Partnership's capital includes general and limited common Partnership Units (“Units”). As of March 31, 2018, the Parent Company owned approximately 99.8% of the Units in the Operating Partnership. The remaining limited Units are owned by investors. As the sole general partner of the Operating Partnership, the Parent Company has exclusive control of the Operating Partnership's day-to-day management.

The Company believes combining the quarterly reports on Form 10-Q of the Parent Company and the Operating Partnership into this single report provides the following benefits:

• Enhances investors' understanding of the Parent Company and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;

• Eliminates duplicative disclosure and provides a more streamlined and readable presentation; and

• Creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

Management operates the Parent Company and the Operating Partnership as one business. The management of the Parent Company consists of the same individuals as the management of the Operating Partnership. These individuals are officers of the Parent Company and employees of the Operating Partnership.

The Company believes it is important to understand the key differences between the Parent Company and the Operating Partnership in the context of how the Parent Company and the Operating Partnership operate as a consolidated company. The Parent Company is a REIT, whose only material asset is its ownership of partnership interests of the Operating Partnership. As a result, the Parent Company does not conduct business itself, other than acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. Except for the $500 million of unsecured public and private placement debt assumed with the Equity One merger on March 1, 2017, the Parent Company does not hold any indebtedness, but guarantees all of the unsecured debt of the Operating Partnership. The Operating Partnership is also the co-issuer and guarantees the $500 million of debt of the Parent Company assumed in the Equity One merger. The Operating Partnership holds all the assets of the Company and retains the ownership interests in the Company's joint ventures. Except for net proceeds from public equity issuances by the Parent Company, which are contributed to the Operating Partnership in exchange for partnership units, the Operating Partnership generates all remaining capital required by the Company's business. These sources include the Operating Partnership's operations, its direct or indirect incurrence of indebtedness, and the issuance of partnership units.

Stockholders' equity, partners' capital, and noncontrolling interests are the main areas of difference between the consolidated financial statements of the Parent Company and those of the Operating Partnership. The Operating Partnership's capital includes general and limited common Partnership Units. The limited partners' units in the Operating Partnership owned by third parties are accounted for in partners' capital in the Operating Partnership's financial statements and outside of stockholders' equity in noncontrolling interests in the Parent Company's financial statements.

In order to highlight the differences between the Parent Company and the Operating Partnership, there are sections in this report that separately discuss the Parent Company and the Operating Partnership, including separate financial statements, controls and procedures sections, and separate Exhibit 31 and 32 certifications. In the sections that combine disclosure for the Parent Company and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of the Company.

As general partner with control of the Operating Partnership, the Parent Company consolidates the Operating Partnership for financial reporting purposes, and the Parent Company does not have assets other than its investment in the Operating Partnership. Therefore, while stockholders' equity and partners' capital differ as discussed above, the assets and liabilities of the Parent Company and the Operating Partnership are the same on their respective financial statements.

REGENCY CENTERS CORPORATION AND REGENCY CENTERS, L.P.

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

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 engages in the ownership, management, leasing, acquisition, and development of retail 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 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.

As of March 31, 2018, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owned 311 retail shopping centers and held partial interests in an additional 118 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 March 31, 2018, the Parent Company owned approximately 99.8% 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”). 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.

Real Estate Partnerships

As of March 31, 2018, Regency had a partial ownership interest in 129 properties through partnerships, of which 11 are consolidated. Regency's partners include institutional investors, other real estate developers and/or operators, and individual parties who had a role in Regency sourcing 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 the 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

13

REGENCY CENTERS CORPORATION AND REGENCY CENTERS, L.P.

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

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 majority of 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.

• 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 Sheets, and Equity in income of investments in real estate partnerships in the Consolidated Statements of Operations. Cash distributions of earnings from operations from 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. Distributed proceeds from debt refinancing and real estate sales in excess of Regency's carrying value of its investment has resulted in a negative investment balance for one partnership, which is recorded within accounts payable and other liabilities in the Consolidated Balance Sheets.

◦ The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is 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.

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.

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)	March 31, 2018		December 31, 2017
Assets
Net real estate investments	$	185,118	172,736
Cash and cash equivalents	4,733		4,993
Liabilities
Notes payable	18,296		16,551
Equity
Limited partners’ interests in consolidated partnerships	17,658		17,572

Revenues and Tenant and Other Receivables

On January 1, 2018, the Company adopted the new accounting guidance for revenue recognition (Topic 606 Revenue from Contracts with Customers, “Topic 606”), as discussed further in the section below, Recent Accounting Pronouncements. Upon adoption of the new standard, certain of the Company's significant accounting policies subject to Topic 606 have been updated.

14

REGENCY CENTERS CORPORATION AND REGENCY CENTERS, L.P.

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

The Company adopted Topic 606 on January 1, 2018, using a modified retrospective approach and applied the transition practical expedients allowed by the standard.  Additionally, the Company applied the practical expedient related to the remaining performance obligations, because all of its performance obligations are satisfied at a point in time, are part of a contract that has an original expected duration of one year or less, or are considered to be a series of performance obligations where variable consideration is allocated entirely to a wholly unsatisfied distinct day of service that forms part of the series, such that the Company does not need to estimate variable consideration to recognize revenue. 

Subsequent to the adoption of Topic 606, the Company recognizes revenue when or as control of the promised services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The following is a description of the Company's revenue from contracts with customers which is in the scope of Topic 606.

Property and Asset Management Services

The Company is engaged under agreements with its joint venture partnerships, which are generally perpetual in nature and cancellable through unanimous partner approval, absent an event of default. Under these agreements, the Company is to provide asset management, property management, and leasing services for the joint ventures' shopping centers. The fees are market-based, generally calculated as a percentage of either revenues earned or the estimated values of the properties managed or the proceeds received, and are recognized over the monthly or quarterly periods as services are rendered. Property management and asset management services represent a series of distinct daily services under the new revenue standard. Accordingly, the Company satisfies its performance obligation as service is rendered each day and the variability associated with that compensation is resolved each day. Amounts due from the partnerships for such services are paid during the month following the monthly or quarterly service periods.

Several of the Company’s partnership agreements provide for incentive payments, generally referred to as “promotes” or “earnouts,” to Regency for appreciation in property values in Regency's capacity as manager. The terms of these promotes are based on appreciation in real estate value over designated time intervals. The Company evaluates its expected promote payout at each reporting period, which generally does not result in revenue recognition until the measurement period has completed, when the amount can be reasonably determined and the amount is not probable of significant reversal.

Leasing Services

Leasing service fees are based on a percentage of the total rent due under the lease. The leasing service is considered performed upon successful execution of an acceptable tenant lease for the joint ventures’ shopping centers, at which time revenue is recognized. Payment of the first half of the fee is generally due upon lease execution and the second half is generally due upon tenant opening or rent payments commencing.

Transaction Services

The Company also receives transaction fees, as contractually agreed upon with each joint venture, which include acquisition fees, disposition fees, and financing service fees. Control of these services is generally transferred to the customer at the time the related transaction closes, which is the point in time when the Company recognizes the related fees. Any unpaid amounts related to transaction-based fees are included in Accounts receivable.

The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $9.3 million and $8.7 million, as of March 31, 2018 and December 31, 2017, respectively.

Real Estate Sales

On January 1, 2018, the Company adopted the new accounting guidance for sales of nonfinancial assets (“Subtopic 610-20”), as discussed further in the section below, Recent Accounting Pronouncements. Upon adoption of the new standard, the Company's accounting policy for real estate sales subject to Subtopic 610-20 has been updated. The Company now derecognizes real estate and recognizes a gain or loss on sales of real estate when a contract exists and control of the property has transferred to the buyer. Control of the property, including controlling financial interest, is generally considered to transfer upon closing through transfer of the legal title and possession of the property. Any retained non-controlling interest is measured at fair value. This change in accounting policy resulted in the recognition, through opening retained earnings on January 1, 2018, of $30.9 million of previously deferred gains from property sales to the Company's Investments in real estate partnerships.

Goodwill

Goodwill 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 350, and allocates its goodwill to its reporting units, which have been determined to be at the individual property level. The Company performs an impairment evaluation of its goodwill at least annually, in November of each year, or more frequently as triggers occur.

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 reporting unit’s fair value is less than its carrying value, including goodwill. If a qualitative approach indicates it is more likely-than-not that the estimated carrying value of a reporting unit (including goodwill) exceeds its fair value, or if the Company chooses to bypass the qualitative approach for any reporting unit, the Company will perform the quantitative approach described below.

The quantitative approach consists of estimating the fair value of each reporting unit 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, 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.

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 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 adopted this ASU on January 1, 2018, using a modified retrospective transition method, which resulted in an immaterial adjustment to opening retained earnings and accumulated other comprehensive income for previously recognized hedge ineffectiveness from off-market hedges.
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.	January 2018	The Company's adoption of this standard did not have a material impact on its results of operations, financialcondition or cash flows as the company has an immaterial amount of equity securities within the scope of this standard. The adoption resulted in reduced disclosure requirements around methodology and significant assumptions used in fair value measurements.
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 adoption of this ASU did not result in a change to the Company's cash flow statement.

Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
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 adoption of this ASU resulted in a change to the classification and presentation of changes in restricted cash on its cash flow statement, which was not material. There was no change to the Company's financial condition or results of operations as a result of adopting this ASU. Upon adoption, and for the three months ended March 31, 2017, net cash provided by operating activities decreased by $67,000 and net cash used in investing activities decreased by $3.4 million, with a corresponding increase in cash and cash equivalents, and restricted cash within the Consolidated Statements of Cash Flows.
ASU 2017-05, February 2017, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (Subtopic 610-20)	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 non-controlling 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	Sales of real estate assets are now accounted for under Subtopic 610-20, which provides for revenue recognition based on transfer of control. For normal arms length property sales to unrelated parties, where Regency has no retained interest in the property, the Company will continue to recognize the full gain or loss upon transfer of control. For property sales in which Regency retains a noncontrolling interest in the property, fair value recognition for the retained noncontrolling interest is now required, which will result in full gain recognition upon loss of control. The Company applied the modified retrospective adoption method, and recognized through opening retained earnings $30.9 million of previously deferred gains from property sales to entities in which Regency had continuing involvement, resulting in a corresponding increase to the value of the Company's investment in those partnerships.

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 supersedes 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. 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 Company utilized the modified retrospective method of adoption, applying the standard to only 2018, and not restating prior periods presented in future financial statements. The majority of the Company's revenue originates from lease contracts and will be subject to Topic 842 to be adopted in January 2019. Beyond revenue from lease contracts, the Company's primary revenue stream, subject to Topic 606 is Management, transaction, and other fees from the Company's real estate partnerships, primarily in the form of property management services, asset management services, and leasing services. The Company evaluated all partnership service relationships and did not identify any changes in the timing or amount of revenue recognition from these revenue streams. The adoption of Topic 606 resulted in additional disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

Not yet adopted:
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 lease obligations for its ground and office leases with a corresponding right of use asset. The Company will continue to recognize a single lease expense for its existing operating leases, currently included in Operating and maintenance expenses and General and administrative expenses, respectively, in the Consolidated Statements of Operations. Ground leases entered or acquired subsequent to the adoption date will likely be considered finance leases, which will result in a slightly accelerated impact to earnings reflected in amortization expense and interest expense. 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 $1.3 million and $10.4 million during the three months ended March 31, 2018 and the year ended December 31, 2017, respectively. Historic capitalization of legal costs was $0.4 million and $1.2 million during the three months ended March 31, 2018 and the year ended December 31, 2017, respectively, including our pro rata share recognized through Equity in income of investments in real estate partnerships. The Company will continue its evaluation of the accounting standard, additional impacts of adoption, and changes in presentation and disclosure requirements.
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.

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

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

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.

Final 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, and allows a measurement period, not to exceed one year from the acquisition date, to finalize the 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, and deferred taxes related to the book tax difference created through purchase accounting. 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 and the deferred tax liability at one of the acquired taxable REIT subsidiaries. The goodwill is not deductible for tax purposes.

The fair 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 fair value estimates for each of the operating properties acquired, and completed the purchase price allocation during the measurement period, which ended during the three months ended March 31, 2018, resulting in an immaterial adjustment to the purchase price allocation.

The following table summarizes the final 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)	Final Purchase Price Allocation
Land	$	2,865,053

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

Significant financing activity during 2018 includes:

• On March 9, 2018, the Company received proceeds from issuing $300.0 million of 4.125% senior unsecured public notes, which priced at 99.837% and mature in March 2028. $60 million of the proceeds were used to repay our Line. Subsequent to quarter-end, $163.2 million was used to early redeem, in April 2018, the senior unsecured public notes originally due June 2020. The remainder of the proceeds are intended to be used to repay 2018 mortgage maturities and for general corporate purposes.

• On March 26, 2018, the Company amended and restated its unsecured revolving credit facility (the “Line”). The amendment and restatement increases the size of the Line to $1.25 billion from $1.0 billion and extends the maturity date to March 23, 2022, with options to extend the maturity for two additional six-month periods. Borrowings will bear interest at an annual rate of LIBOR plus 87.5 basis points, subject to the Company’s credit ratings, compared to a rate of 92.5 basis points under its previous facility. An annual facility fee of 15 basis points, subject to the Company’s credit ratings, applies to the entire $1.25 billion Line.    

Subsequent Event

On April 2, 2018, the Company paid $163.2 million, including accrued and unpaid interest through the redemption date and a make-whole amount, to redeem its outstanding $150.0 million 6% Senior Unsecured Notes originally due June 15, 2020. As noted above, the Company used proceeds from its March 9, 2018 offering to fund the redemption.

As of March 31, 2018, scheduled principal payments and maturities on notes payable and unsecured credit facilities were as follows:

(in thousands)	March 31, 2018
Scheduled Principal Payments and Maturities by Year:	Scheduled Principal Payments		Mortgage Loan Maturities	Unsecured Maturities (1)			Total

(1)  Includes unsecured public debt and unsecured credit facilities.
(2)  On April 2, 2018, the Company redeemed its outstanding $150.0 million 6.0% senior unsecured public notes, due June 15, 2020, for a redemption price of $163.2 million, including accrued and unpaid interest through the redemption date and a make-whole amount.

The Company has $135.8 million of mortgage loans maturing through 2019, which it currently intends to repay if wholly owned, or refinance if held within a consolidated real estate investment partnership. The Company has sufficient capacity on its Line to repay this maturing debt, all of which is in the form of non-recourse mortgage loans.

The Company was in compliance as of March 31, 2018 with the financial and other covenants under its unsecured public and private placement debt and unsecured credit facilities.

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

25

REGENCY CENTERS CORPORATION AND REGENCY CENTERS, L.P.

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

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)

(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 March 31, 2018, 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.

As of March 31, 2018, the Company expects $4.4 million of net deferred losses on derivative instruments in accumulated other comprehensive income, 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 reclass is $8.4 million which is related to previously settled swaps on the Company's ten year fixed rate unsecured loans.

7.    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:

	March 31, 2018			December 31, 2017
(in thousands)	Carrying Amount		Fair Value	Carrying Amount		Fair Value
Financial assets:
Notes receivable	$	16,316	16,345	$	15,803	15,660
Financial liabilities:
Notes payable	$	3,276,888	3,291,803	$	2,971,715	3,058,044
Unsecured credit facilities	$	563,380	565,000	$	623,262	625,000

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 March 31, 2018 and December 31, 2017, 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

27

REGENCY CENTERS CORPORATION AND REGENCY CENTERS, L.P.

Notes to Unaudited Consolidated Financial Statements

March 31, 2018

value of securities are recorded within net investment (income) loss in the accompanying Consolidated Statements of Operations.

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 March 31, 2018

The impairment of the real estate, which is classified as held and used as of March 31, 2018, was determined based on the expected selling price as compared to the Company's carrying value of its investment.

There were no assets measured at fair value on a nonrecurring basis as of December 31, 2017.

8.    Equity and Capital

Common Stock of the Parent Company

At the Market ("ATM") Program

There were no shares issued under the ATM equity program during the three months endedMarch 31, 2018 or 2017.

Share Repurchase Program

On February 7, 2018, the Company's Board authorized a common share repurchase program under which the Company may purchase, from time to time, $250 million worth of shares of its outstanding common stock through open market purchases and/or in privately negotiated transactions. Any shares purchased will be retired. The program is scheduled to expire on February 6, 2020. The timing and actual number of shares purchased under the program depend upon marketplace conditions and other factors. The program remains subject to the discretion of the board. Through March 31, 2018, the Company had repurchased 2,145,209 shares for $125.0 million at an average price of $58.24 per share.

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.

Income allocated to noncontrolling interests of the Operating Partnership has been excluded from the numerator and exchangeable Operating Partnership units have been omitted from the denominator for the purpose of computing diluted earnings per share since the effect of including these amounts in the numerator and denominator would have no impact. Weighted average exchangeable Operating Partnership units outstanding for the three months endedMarch 31, 2018 and 2017 were 349,902 and 154,170, respectively.

12.    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.

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 March 31, 2018 and December 31, 2017, the Company had $9.4 million and $9.4 million in letters of credit outstanding, respectively.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

In addition to historical information, the following information contains forward-looking statements as defined under federal securities laws. These forward-looking statements include statements about anticipated changes in our revenues, the size of our development and redevelopment program, earnings per share and unit, returns and portfolio value, and expectations about our liquidity. These statements are based on current expectations, estimates and projections about the real estate industry and markets in which the Company operates, and management's beliefs and assumptions. Forward-looking statements are not guarantees of future performance and involve certain known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied by such statements. Such risks and uncertainties include, but are not limited to changes in national and local economic conditions, financial difficulties of tenants, competitive market conditions, including timing and pricing of acquisitions and sales of properties and building pads ("out-parcels"), changes in leasing activity and market rents, timing of development starts, meeting development schedules, natural disasters in geographic areas in which we operate, cost of environmental remediation, our inability to exercise voting control over the co-investment partnerships through which we own many of our properties, and technology disruptions. For additional information, see “Risk Factors” included here in and in our Annual Report on Form 10-K for the year ended December 31, 2017. The following discussion should be read in conjunction with the accompanying Consolidated Financial Statements and Notes thereto of Regency Centers Corporation and Regency Centers, L.P. appearing elsewhere herein. We do not undertake any obligation to release publicly any revisions to such forward-looking statements to reflect events or uncertainties after the date hereof or to reflect the occurrence of uncertain events.

Defined Terms

We use certain non-GAAP performance measures, in addition to the required GAAP presentation, as we believe these measures improve the understanding of the Company's operational results. We manage our entire real estate portfolio without regard to ownership structure, although certain decisions impacting properties owned through partnerships require partner approval. Therefore, we believe presenting our pro-rata share of certain operating metrics regardless of ownership structure, along with other non-GAAP measures, makes comparisons of other REITs' operating results to the Company's more meaningful. We continually evaluate the usefulness, relevance, limitations, and calculation of our reported non-GAAP performance measures to determine how best to provide relevant information to the public, and thus such reported measures could change.

The following terms, as defined, are commonly used by management and the investing public to understand and evaluate our operational results:

• Same Property is a Retail Operating Property that was owned and operated for the entirety of both calendar year periods being compared. This term excludes all Properties in Development and Non-Same Properties.

For purposes of evaluating same property NOI on a comparative basis, and in light of the merger with Equity One on March 1, 2017, we are considering properties acquired through the Equity One merger as Same Property if those properties would have met that criteria from Equity One's ownership of the properties. See Supplemental Earnings Information, later in this document, for further discussion and use of Equity One information for pro-rata same property NOI, as adjusted.

• A Non-Same Property is a property acquired, sold, or a Development Completion during either calendar year period being compared. Non-retail properties and corporate activities, including the captive insurance program, are part of Non-Same Property.

• A Retail Operating Property is any retail property not termed a Property in Development. A retail property is any property where the majority of the income is generated from retail uses.

• Property In Development includes land or Retail Operating Properties in various stages of development and redevelopment including active pre-development activities.

• Development Completion is a project in development that is deemed complete upon the earliest of: (i) 90% of total estimated net development costs have been incurred and percent leased equals or exceeds 95%, or (ii) the project features at least two years of anchor operations, or (iii) three years have passed since the start of construction. Once deemed complete, the property is termed a Retail Operating Property.

• Pro-Rata information includes 100% of our consolidated properties plus our economic share (based on our ownership interest) in our unconsolidated real estate investment partnerships.

33

The pro-rata information is prepared on a basis consistent with the comparable consolidated amounts and is intended to more accurately reflect our proportionate economic interest in the operating results of properties in our portfolio. We do not control the unconsolidated investment partnerships, and the pro-rata presentations of the assets and liabilities, and revenues and expenses do not represent our legal claim to such items. The partners are entitled to profit or loss allocations and distributions of cash flows according to the operating agreements, which provide for such allocations according to their invested capital. Our share of invested capital establishes the ownership interests we use to prepare our pro-rata share.

The presentation of pro-rata information has limitations which include, but are not limited to, the following:

• The amounts shown on the individual line items were derived by applying our overall economic ownership interest percentage determined when applying the equity method of accounting or allocating noncontrolling interests, and do not necessarily represent our legal claim to the assets and liabilities, or the revenues and expenses; and

• Other companies in our industry may calculate their pro-rata interest differently, limiting the comparability of pro-rata information.

Because of these limitations, the pro-rata financial information should not be considered independently or as a substitute for our financial statements as reported under GAAP. We compensate for these limitations by relying primarily on our GAAP financial statements, using the pro-rata information as a supplement.

• Operating EBITDAre (previously Adjusted EBITDA) begins with the National Association of Real Estate Investment Trusts ("NAREIT") EBITDAre and excludes certain non-cash components of earnings derived from above and below market rent amortization and straight-line rents. NAREIT EBITDAre is a measure of REIT performance, which the NAREIT defines as net income, computed in accordance with GAAP, excluding interest expense, income tax expense, depreciation and amortization, gains and losses from sales of depreciable property, operating real estate impairments, and adjustments to reflect the Company's share of unconsolidated partnerships and joint ventures. The NAREIT EBITDAre performance measure was adopted for reporting periods beginning after December 31, 2017.

• Fixed Charge Coverage Ratio is defined as Operating EBITDAre divided by the sum of the gross interest and scheduled mortgage principal paid to our lenders plus dividends paid to our preferred stockholders.

• Net Operating Income ("NOI") is the sum of base rent, percentage rent, and recoveries from tenants and other income, less operating and maintenance, real estate taxes, ground rent, and provision for doubtful accounts. NOI excludes straight-line rental income and expense, above and below market rent and ground rent amortization, tenant lease inducement amortization, and other fees. The Company also provides disclosure of NOI excluding termination fees, which excludes both termination fee income and expenses.

• NAREIT Funds from Operations ("NAREIT FFO") is a commonly used measure of REIT performance, which NAREIT defines as net income, computed in accordance with GAAP, excluding gains and losses from sales of depreciable property, net of tax, excluding operating real estate impairments, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. We compute NAREIT FFO for all periods presented in accordance with NAREIT's definition. Many companies use different depreciable lives and methods, and real estate values historically fluctuate with market conditions. Since NAREIT FFO excludes depreciation and amortization and gains and losses from depreciable property dispositions, and impairments, it provides a performance measure that, when compared year over year, reflects the impact on operations from trends in occupancy rates, rental rates, operating costs, acquisition and development activities, and financing costs. This provides a perspective of our financial performance not immediately apparent from net income determined in accordance with GAAP. Thus, NAREIT FFO is a supplemental non-GAAP financial measure of our operating performance, which does not represent cash generated from operating activities in accordance with GAAP; and, therefore, should not be considered a substitute measure of cash flows from operations. The Company provides a reconciliation of Net Income (Loss) Attributable to Common Stockholders to NAREIT FFO.

Overview of Our Strategy

Regency Centers Corporation began its operations as a publicly-traded REIT in 1993, and, as of March 31, 2018, had full or partial ownership interests in 429 retail properties primarily anchored by market leading grocery stores. Our properties are principally located in affluent and infill trade areas of the United States, and contain 54.2 million square feet ("SF") of gross leasable area ("GLA"). All of our operating, investing, and financing activities are performed through our Operating Partnership, Regency Centers, L.P., our wholly-owned subsidiaries, and through our co-investment partnerships.

As of March 31, 2018, the Parent Company owns approximately 99.8% of the outstanding common partnership units of the Operating Partnership.

Our mission is to be the preeminent national shopping center owner, operator and developer. Our strategy is to:

• Own and manage an unequaled portfolio of high-quality neighborhood and community shopping centers anchored by market leading grocers and located in affluent suburban and near urban trade areas in the country’s most desirable metro areas. We expect this combination will produce highly desirable and attractive centers with best-in-class retailers. These centers should command higher rental and occupancy rates resulting in excellent prospects to grow net operating income ("NOI");

• Maintain an industry leading and disciplined development and redevelopment platform to deliver exceptional retail centers at higher margins as compared to acquisitions;

• Support our business activities with a strong balance sheet; and

• Engage a talented, dedicated team of employees, who are guided by Regency’s strong values and special culture, which are aligned with shareholder interests.

Executing on our Strategy

During the three months endedMarch 31, 2018:

We had Net income (loss) attributable to common stockholders of $52.7 million as compared to $(33.2) million, net of $69.8 million of merger costs, during the three months ended March 31, 2017.

We sustained superior same property NOI growth compared to the average of our shopping center peers:

• We achieved pro-rata same property NOI growth, as adjusted, excluding termination fees, of 4.0%.

• We executed 353 leasing transactions representing 1.0 million pro-rata SF of new and renewal leasing, with trailing twelve month rent spreads of 7.9% on comparable retail operating property spaces.

• At March 31, 2018, our total property portfolio was 95.1% leased, while our same property portfolio was 95.7% leased.

We developed and redeveloped high quality shopping centers at attractive returns on investment:

• We started one new development representing a total pro-rata project investment of $31.1 million upon completion, with a projected return on investment of 6.3%.

• Including the one new development project, a total of 19 properties were in the process of development or redevelopment, representing a pro-rata investment upon completion of $454.3 million.

We maintained a conservative balance sheet providing financial flexibility to cost effectively fund investment opportunities and debt maturities:

• On March 9, 2018, the Company received proceeds from $300.0 million of 4.125% senior unsecured public notes, which priced at 99.837% and mature in March 2028. $60 million of the proceeds were used to repay our Line. Subsequent to quarter-end, we used $163.3 million to early redeem in April 2018 our senior unsecured public notes originally due June 2020. We intend to use the remainder of the proceeds to repay 2018 mortgage maturities and for general corporate purposes.

• On March 26, 2018, we amended and restated our unsecured revolving credit facility (the “Line”). The amendment and restatement increases the size of the Line to $1.25 billion from $1.0 billion and extends the maturity date to March 23, 2022, with options to extend maturity for two additional six-month periods. Borrowings will bear interest at an annual rate of LIBOR plus 87.5 basis points, subject to our credit ratings, compared to a rate of 92.5 basis points under

35

its previous facility. An annual facility fee of 15 basis points, subject to our credit ratings, applies to the entire $1.25 billion Line.

• On April 2, 2018, we redeemed the outstanding $150.0 million 6.0% senior unsecured public notes, due June 15, 2020, for a redemption price of $163.2 million, including accrued and unpaid interest through the redemption date and a make-whole amount.

• At March 31, 2018, our annualized net debt-to-operating EBITDAre ratio on a pro-rata basis was 5.6x.

Shopping Center Portfolio

The following table summarizes general information related to the Consolidated Properties in our shopping center portfolio:

(GLA in thousands)	March 31, 2018	December 31, 2017
Number of Properties	311	311
Properties in Development	8	8

% Leased – Operating	95.6%	96.0%
Weighted average annual effective rent per square foot ("PSF"), net of tenant concessions.	$21.15	$21.01

The following table summarizes general information related to the Unconsolidated Properties owned in co-investment partnerships in our shopping center portfolio:

(GLA in thousands)	March 31, 2018	December 31, 2017
Number of Properties	118	115

% Leased –Operating	95.4%	96.2%
Weighted average annual effective rent PSF, net of tenant concessions	$20.82	$20.63

For the purpose of the following disclosures of occupancy and leasing activity, "anchor space" is considered space greater than or equal to 10,000 SF and "shop space" is less than 10,000 SF. The following table summarizes pro-rata occupancy rates of our combined Consolidated and Unconsolidated shopping center portfolio:

	March 31, 2018	December 31, 2017
% Leased – Operating	95.6%	96.2%
Anchor space	97.6%	98.3%
Shop space	92.2%	92.5%

The decline in anchor space percent leased is primarily attributable to anticipated anchor move-outs. The decline in shop space percent leased is consistent with historical seasonal move-outs experienced during the first quarter.

Significant Tenants and Concentrations of Risk

We seek to reduce our operating and leasing risks through geographic diversification and by avoiding dependence on any single property, market, or tenant. The following table summarizes our most significant tenants, based on their percentage of annualized base rent:

		March 31, 2018
Grocery Anchor		Number of Stores	Percentage of Company- owned GLA (1)	Percentage  of Annualized Base Rent (1)
Publix		69	6.2%	3.1%
Kroger		58	6.6%	3.1%
Albertsons/Safeway	(2)	46	4.0%	2.9%
TJX Companies		59	3.3%	2.4%
Whole Foods		28	2.2%	2.3%
(1) Includes Regency's pro-rata share of Unconsolidated Properties and excludes those owned by anchors.
(2)  Upon completion of the pending merger of Albertsons Cos. and Rite Aid Corp., the combined company would represent a total of 60 stores, 4.4% of Company-owned GLA, and 3.2% of annualized base rent, based on active leases as of March 31, 2018. There is the possibility that store closures could occur as a result of the merger.

Bankruptcies and Credit Concerns

Our management team devotes significant time to researching and monitoring retail trends, consumer preferences, customer shopping behaviors, changes in retail delivery methods, and changing demographics in order to anticipate the challenges and opportunities impacting the retail industry. A greater shift to e-commerce, large-scale retail business failures, and tight credit markets could negatively impact consumer spending and have an adverse effect on our results of operations. We seek to mitigate these potential impacts through tenant diversification, replacing weaker tenants with stronger operators, anchoring our centers with market leading grocery stores that drive foot traffic, and maintaining a presence in affluent suburbs and dense infill trade areas. As a result of our research and findings, we may reduce new leasing, suspend leasing, or curtail allowances for construction of leasehold improvements within a certain retail category or to a specific retailer in order to reduce our risk from bankruptcies and store closings.

We closely monitor the operating performance and rent collections of tenants in our shopping centers as well as those retailers experiencing significant changes to their business models as a result of reduced customer traffic in their stores and increased competition from e-commerce sales.  Retailers who are unable to withstand these and other business pressures may file for bankruptcy. Although base rent is supported by long-term lease contracts, tenants who file bankruptcy generally have the legal right to reject any or all of their leases and close related stores. Any unsecured claim we hold against a bankrupt tenant for unpaid rent might be paid only to the extent that funds are available and only in the same percentage as is paid to all other holders of unsecured claims. As a result, it is likely that we would recover substantially less than the full value of any unsecured claims we hold. Additionally, we may incur significant expense to recover our claim and to release the vacated space. In the event that a tenant with a significant number of leases in our shopping centers files bankruptcy and cancels its leases, we could experience a significant reduction in our revenues. Tenants who have filed for bankruptcy and continue to occupy space in our shopping centers represent an aggregate of 0.3% of our annual base rent on a pro-rata basis.

Results from Operations

Comparison of the three months endedMarch 31, 2018 to 2017:

Results from operations for the three months endedMarch 31, 2018 reflect the results of our merger with Equity One on March 1, 2017.

Our revenues increased as summarized in the following table:

	Three months ended March 31,
(in thousands)	2018		2017	Change
Minimum rent	$	201,392	141,240	60,152
Percentage rent	3,873		2,906	967
Recoveries from tenants	58,881		42,087	16,794
Other income	5,389		3,192	2,197
Management, transaction, and other fees	7,158		6,706	452
Total revenues	$	276,693	196,131	80,562

Minimum rent increased, on a net basis, as follows:

• $2.3 million increase from development properties;

• $2.4 million increase from acquisitions of operating properties;

• $56.4 million increase from same properties, including

◦ $53.8 million increase from properties acquired through the Equity One merger on March 1, 2017,

◦ $1.4 million increase from redevelopments, and

◦ $1.3 million increase from rental rate growth and rent commencements within the existing same property portfolio;

• reduced by $957,000 from the sale of operating properties.

Percentage rent increased $967,000 primarily from same properties acquired through the Equity One merger.

Recoveries from tenants represent reimbursements to us for tenants' pro-rata share of the operating, maintenance, and real estate tax expenses that we incur to operate our shopping centers. Recoveries from tenants increased, on a net basis, as follows:

• $518,000 increase from rent commencing at development properties;

• $542,000 increase from acquisitions of operating properties;

• $16.0 million increase from same properties, including $15.0 million from properties acquired through the Equity One merger;

• reduced by $256,000 from the sale of operating properties.

Other income, which consists of incidental income earned at our centers, increased $2.2 million from same properties, including $1.6 million from properties acquired through the Equity One merger.

Management, transaction, and other fees includes property management, asset management, leasing and other transaction-related services provided primarily to our real estate partnerships. The increase during 2018 is attributable to the additional partnerships acquired through the Equity One merger on March 1, 2017.

39

Changes in our operating expenses are summarized in the following table:

	Three months ended March 31,
(in thousands)	2018		2017	Change
Depreciation and amortization	$	88,525	60,053	28,472
Operating and maintenance	42,516		29,763	12,753
General and administrative	17,606		17,673	(67	)
Real estate taxes	30,425		21,450	8,975
Other operating expenses	1,632		71,512	(69,880	)
Total operating expenses	$	180,704	200,451	(19,747	)

Depreciation and amortization costs increased, on a net basis, as follows:

• $787,000 increase as we began depreciating costs at development properties where tenant spaces were completed and became available for occupancy;

• $1.4 million increase from acquisitions of operating properties;

• $26.7 million increase from same properties, including $25.8 million from properties acquired through the Equity One merger; offset by

• $297,000 decrease from the sale of operating properties.

Operating and maintenance costs increased, on a net basis, as follows:

• $806,000 increase from operations commencing at development properties;

• $846,000 net increase from acquired properties and claims expense within the company's captive insurance program;

• $11.3 million increase from same properties, including $11.0 million from properties acquired through the Equity One merger;

• reduced by $240,000 from the sale of operating properties.

General and administrative costs remained consistent during the three months endedMarch 31, 2018 and 2017, with offsetting changes in the following areas:

• $1.0 million increase in expenses due to lower capitalization of leasing overhead, which varies based on volume and mix of leasing transactions, offset by

• $1.0 million decrease in deferred compensation plan related to unrealized losses within participant accounts.

Real estate taxes increased, on a net basis, as follows:

• $478,000 increase from development properties where capitalization ceased as tenant spaces became available for occupancy;

• $395,000 increase from acquisitions of operating properties;

• $8.3 million increase within the same property portfolio, including $7.4 million of real estate taxes from properties acquired through the Equity One merger, with the balance of changes resulting from increased tax assessments;

• reduced by $175,000 from sold properties.

Other operating expenses decreased $69.9 million primarily attributable to transaction costs recognized from the Equity One merger in March 2017.

The following table presents the components of other expense (income):

	Three months ended March 31,
(in thousands)	2018			2017		Change
Interest expense, net
Interest on notes payable	$	32,968		24,613		8,355
Interest on unsecured credit facilities	4,288			2,430		1,858
Capitalized interest	(2,179		)	(1,257	)	(922	)
Hedge expense	2,102			2,102		—
Interest income	(394		)	(689	)	295
Interest expense, net	36,785			27,199		9,586
Provision for impairment	16,054			—		16,054
Early extinguishment of debt	162			—		162
Net investment income	(32		)	(1,097	)	1,065
Total other expense (income)	$	52,969		26,102		26,867

The $9.6 million net increase in total interest expense is due to:

• $8.4 million net increase in interest on notes payable from:

◦ $791,000 of additional interest on issuance of $300 million of new unsecured debt in March 2018,

◦ $5.0 million of additional interest on notes payable assumed with the Equity One merger; and

◦ $4.7 million increase from issuances of $950 million of new unsecured debt during 2017;

◦ offset by $2.1 million decrease in mortgage interest expense primarily due to the payoff of nine mortgages utilizing proceeds from the June 2017 debt offering; and

• $1.9 million increase in interest on unsecured credit facilities related to higher average balances including a new $300 million term loan which closed on March 1, 2017;

• offset by $922,000 decrease from higher capitalization of interest based on the size and progress of development and redevelopment projects in process.

During the three months endedMarch 31, 2018, we recognized a $16.1 million impairment loss on two operating properties, one that has sold and one that is held and used, which includes $1.7 million of goodwill impairment. The Company will, from time to time, identify properties ("reporting units") that no longer meet its investment criteria and will evaluate the property for potential sale. A decision to sell a reporting unit would result in the need to evaluate its goodwill for recoverability and may result in impairment. If events occur that trigger an impairment evaluation at multiple reporting units, the resulting goodwill impairment may be significant.

Net investment income decreased $1.1 million, driven by changes in unrealized gains and losses of plan assets held in the non-qualified deferred compensation plan. The unrealized investment losses are offset by changes in participant obligations recognized within general and administrative expenses.

Our equity in income of investments in real estate partnerships increased as follows:

		Three months ended March 31,

Total equity in income of investments in real estate partnerships		$	10,349		9,342	1,007

The $1.0 million increase in our equity in income of investments in real estate partnerships is largely attributed to:

•GRIR increased $449,000 from greater rental income from rent growth and percent commenced, coupled with lower depreciation expense, as several assets are now fully depreciated.

•Other investments in real estate partnerships increased $701,000 from

◦$300,000 increase from the addition of a real estate partnership acquired through the Equity One merger,

◦$150,000 increase from a new partnership investment made during the three months endedMarch 31, 2018,

◦$115,000 increase from a gain on sale recognized within another partnership, and

◦the remaining change is attributable to normal changes in operations.

The following represents the remaining components that comprised net income attributable to the common stockholders and unit holders:

	Three months ended March 31,

Net income (loss) attributable to common unit holders	$	52,771		(33,242	)	86,013

In February and August of 2017 we redeemed our Series 6 and Series 7 preferred stock.

Supplemental Earnings Information

We use certain non-GAAP performance measures, in addition to certain performance metrics determined under GAAP, as we believe these measures improve the understanding of the Company's operating results. We manage our entire real estate portfolio without regard to ownership structure, although certain decisions impacting properties owned through partnerships require partner approval. Therefore, we believe presenting our pro-rata share of operating results regardless of ownership structure, along with other non-GAAP measures, may assist in comparing the Company's operating results to other REITs. We continually evaluate the usefulness, relevance, limitations, and calculation of our reported non-GAAP performance measures to determine how best to provide relevant information to the public, and thus such reported measures could change. See "Defined Terms" at the beginning of this Management's Discussion and Analysis.

Pro-Rata Same Property NOI:

For purposes of evaluating same property NOI on a comparative basis, and in light of the merger with Equity One on March 1, 2017, we are presenting our same property NOI on a pro forma basis as if the merger had occurred January 1, 2017. This perspective allows us to evaluate same property NOI growth over a comparable period. The pro forma same property NOI as adjusted is not necessarily indicative of what the actual same property NOI and growth would have been if the merger had occurred on January 1, 2017, nor does it purport to represent the same property NOI and growth for future periods.

Our pro-rata same property NOI as adjusted, excluding termination fees, changed from the following major components:

	Three months ended March 31,

(1) Adjusted for Equity One operating results prior to the merger for these periods. For additional information and details about the Equity One operating results included herein, refer to the Same Property NOI Reconciliation at the end of the Supplemental Earnings section.

Base rent increased $7.8 million during the three months endedMarch 31, 2018, driven by increases in rental rate growth on new and renewal leases, contractual rent steps from leases, and rent commencement at redevelopments.

Recoveries from tenants increased $2.9 million during the three months endedMarch 31, 2018, as a result of increases in recoverable costs, as noted below.

Other income increased $1.1 million during the three months endedMarch 31, 2018, due to the timing of settlement income and other fee income.

Operating expenses increased $3.0 million during the three months endedMarch 31, 2018, primarily due to higher snow removal costs and higher real estate taxes.

Liquidity and Capital Resources

General

We use cash flows generated from operating, investing, and financing activities to strengthen our balance sheet, finance our development and redevelopment projects, fund our investment activities, and maintain financial flexibility. We continuously monitor the capital markets and evaluate our ability to issue new debt or equity, to repay maturing debt, or fund our capital commitments.

Except for the $500 million of unsecured public and private placement debt assumed with the Equity One merger in 2017, our Parent Company has no capital commitments other than its guarantees of the commitments of our Operating Partnership. All remaining debt is held by our Operating Partnership or by our co-investment partnerships. The Operating Partnership is a co-issuer and a guarantor of the $500 million of outstanding debt of our Parent Company assumed in the Equity One merger. The Parent Company will from time to time access the capital markets for the purpose of issuing new equity and will simultaneously contribute all of the offering proceeds to the Operating Partnership in exchange for additional partnership units. Based upon our available sources of capital, our current credit ratings, and the number of high quality, unencumbered properties we own, we believe our available capital resources are sufficient to meet our expected capital needs.    

In addition to our $87.9 million of cash, we have the following additional sources of capital available:

(in thousands)	March 31, 2018
ATM equity program
Original offering amount	$	500,000
Available capacity	$	500,000
Line of Credit
Total commitment amount	$	1,250,000
Available capacity (1)	$	1,240,600
Maturity (2)	May 23, 2022
(1)  Net of letters of credit.
(2)  The Company has the option to extend the maturity for two additional six-month periods.

We operate our business such that we expect net cash provided by operating activities will provide the necessary funds to pay our distributions to our common and preferred share and unit holders, which were $95.0 million and $56.6 million for the three months endedMarch 31, 2018 and 2017, respectively. In March 2018, we expanded our line of credit to $1.25 billion with a maturity date of May 23, 2022. We currently do not have any preferred shares issued and outstanding. Our dividend distribution policy is set by our Board of Directors, who monitors our financial position. Our Board of Directors recently declared our common stock dividend of $0.555 per share, payable on May 30, 2018. Future dividends will be declared at the discretion of our Board of Directors and will be subject to capital requirements and availability. We plan to continue paying an aggregate amount of distributions to our stock and unit holders that, at a minimum, meet the requirements to continue qualifying as a REIT for federal income tax purposes.

During the next twelve months, we estimate that we will require approximately $493.1 million of cash, including $215.1 million to complete in-process developments and redevelopments, $263.7 million to repay maturing debt, and $14.3 million to fund our pro-rata share of estimated capital contributions to our co-investment partnerships for repayment of maturing debt. If we start new developments, redevelop additional shopping centers, commit to new acquisitions, prepay debt prior to maturity, or repurchase shares of our common stock, our cash requirements will increase. If we refinance maturing debt, our cash requirements will decrease. To meet our cash requirements, we may utilize cash generated from operations, proceeds from the sale of real estate, available borrowings from our Line, and when the capital markets are favorable, proceeds from the sale of equity or the issuance of new long-term debt. In addition, we are under contract to purchase, through November 2019, up to 100% ownership interest in an operating shopping center valued at $205.0 million. We are currently expecting to be able to purchase a 30% ownership interest in the property by November 2019.

We endeavor to maintain a high percentage of unencumbered assets. At March 31, 2018, 85.5% of our wholly-owned real estate assets were unencumbered. Such assets allow us to access the secured and unsecured debt markets and to maintain availability on the Line. Our annualized Fixed charge coverage ratio, including our pro-rata share of our partnerships, was 4.1 times for the periods ended March 31, 2018 and December 31, 2017, respectively.

46

Our Line, Term Loans, and unsecured loans require that we remain in compliance with various covenants, which are described in the Notes to Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2017. We are in compliance with these covenants at March 31, 2018 and expect to remain in compliance.

Summary of Cash Flow Activity

The following table summarizes net cash flows related to operating, investing, and financing activities of the Company:

	Three months ended March 31,
(in thousands)	2018			2017		Change
Net cash provided by operating activities	$	149,868		32,656		117,212
Net cash used in investing activities	(107,206		)	(686,515	)	579,309
Net cash provided by financing activities	1,593			680,822		(679,229	)
Net increase in cash and cash equivalents and restricted cash	$	44,255		26,963		17,292
Total cash and cash equivalents and restricted cash	$	93,636		44,842		48,794

Net cash provided by operating activities:

Net cash provided by operating activities increased $117.2 million due to:

• $104.9 million increase in cash from operating income attributable to the additional cash flow from properties acquired through the Equity One merger in March 2017, net of merger costs;

• $0.5 million increase in operating cash flow distributions from our unconsolidated real estate partnerships; and,

• $11.8 million net increase in cash due to timing of cash receipts and payments related to operating activities, primarily from the payment of merger costs previously accrued.

Net cash used in investing activities:

Net cash used in investing activities decreased by $579.3 million as follows:

	Three months ended March 31,

Net cash used in investing activities	$	(107,206	)	(686,515	)	579,309

Significant changes in investing activities include:

• We acquired an operating property for $20.1 million during 2018 and, other than those included in the merger, we did not acquire any operating properties during the same period in 2017.

47

• We issued 65.5 million shares of common stock to the shareholders of Equity One valued at $4.5 billion in a stock for stock exchange and merged Equity One into the Company on March 1, 2017. As part of the merger, we paid $648.7 million, net of cash acquired, to repay Equity One credit facilities not assumed with the merger.

• We invested $11.3 million less in 2018 than the same period in 2017 on real estate development and capital improvements, as further detailed in a table below.

• We invested $39.3 million in our real estate partnerships during 2018, including $32.7 million to fund our share of acquiring two operating properties, $3.4 million to acquire an interest in one land parcel for development, and $3.2 million to fund our share of development and redevelopment activities, compared to $1.7 million during the same period in 2017 for redevelopment activity.

• Distributions from our unconsolidated real estate partnerships include return of capital from sales or financing proceeds. The $2.3 million received in 2018 is driven by the sale of one land parcel. During the same period in 2017, we received $25.4 million of financing proceeds from encumbering certain operating properties within one partnership.

• Acquisition of securities and proceeds from sale of securities pertain to investments held in our captive insurance company and our deferred compensation plan.

We plan to continue developing and redeveloping shopping centers for long-term investment. We deployed capital of $52.0 million for the development, redevelopment, and improvement of our real estate properties, comprised of the following:

	Three months ended March 31,
(in thousands)	2018		2017	Change
Capital expenditures:
Land acquisitions for development / redevelopment	$	—	7,642	(7,642	)
Building and tenant improvements	11,922		8,105	3,817
Redevelopment costs	15,551		22,407	(6,856	)
Development costs	18,447		17,747	700
Capitalized interest	2,062		1,061	1,001
Capitalized direct compensation	3,986		6,295	(2,309	)
Real estate development and capital improvements	$	51,968	63,257	(11,289	)

• During 2018 we acquired no land parcels for new development projects as compared to one land parcel acquired during 2017.

• Building and tenant improvements increased $3.8 million in 2018, primarily related to the overall increase in the size of our portfolio from the merger with Equity One in March 2017.

• We intend to continuously improve our portfolio of shopping centers through redevelopment which can include adjacent land acquisition, existing building expansion, facade renovation, new out-parcel building construction, and redevelopment related tenant improvement costs.  The size and magnitude of each redevelopment project varies with each redevelopment plan. Redevelopment expenditures are lower in 2018 due to the timing, magnitude, and number of projects currently in process.

• Development expenditures remained consistent. At March 31, 2018 and December 31, 2017, we had eight consolidated development projects that were either under construction or in lease up. See the tables below for more details about our development projects.

• Interest is capitalized on our development and redevelopment projects and is based on cumulative actual costs expended. We cease interest capitalization when the property is no longer being developed or is available for occupancy upon substantial completion of tenant improvements, but in no event would we capitalize interest on the project beyond 12 months after the anchor opens for business.

• We have a staff of employees who directly support our development and redevelopment programs. Internal compensation costs directly attributable to these activities are capitalized as part of each project. Changes in the level of future development and redevelopment activity could adversely impact results of operations by reducing the amount of internal costs for development and redevelopment projects that may be capitalized. A

48

10% reduction in development and redevelopment activity without a corresponding reduction in development related compensation costs could result in an additional charge to net income of $1.5 million per year.

Significant financing activities during the three months endedMarch 31, 2018 and 2017 include the following:

• We repurchased for cash a portion of the common stock related to stock based compensation to satisfy employee federal and state tax withholding requirements. The 2017 repurchases were higher due to the vesting of Equity One's stock-based compensation program as a result of the merger.

• We paid $125.0 million to repurchase common shares through our repurchase program.

• We redeemed all of the issued and outstanding shares of our 6.625% Series 6 cumulative redeemable preferred stock on February 16, 2017.

• We paid $38.4 million of additional dividends as a result of the additional common shares outstanding, as common shares were issued as merger consideration during 2017, combined with an increase in our quarterly dividend rate from $0.510 per share, during the three months endedMarch 31, 2017, to $0.555 per share, during the three months endedMarch 31, 2018.

• We had the following debt related activity during 2018:

We issued, in March, $300.0 million of senior unsecured public notes and received proceeds of $299.5 million, of which $60 million were used to repay our Line. Subsequent to quarter-end, we used $163.3 million to early redeem in April 2018 our senior unsecured public notes originally due June 2020. We intend to use the remainder of the proceeds to repay 2018 mortgage maturities totaling $112.2 million, and for general corporate purposes.

We drew $1.7 million on a construction loan to fund an in-process development project.

We paid $2.9 million to pay scheduled principal mortgage payments, and $9.0 million of loan costs in connection with our $300.0 million public note offering and expanding our Line commitment.

• We had the following debt related activity during 2017:

We received $300.0 million of proceeds upon closing on a new term loan. The combined funding from the term loan and borrowings on our Line, net of repayments, provided $380.0 million to pay a $300.0 million Equity One term loan that became due upon merger and to pay merger related transaction costs.

We issued $650.0 million of senior unsecured public notes and received proceeds of $648.0 million, which were used to redeem all of our $250.0 million Series 6 preferred stock and to repay Equity One's credit facilities not assumed by the Company in the merger.

50

We paid $12.8 million to repay maturing mortgage loans and pay scheduled principal payments and $8.8 million of loan costs in connection with the new debt issued above and expanding our Line commitment.

Total	$	73,979	1,417,694		19,635	1,511,308		519,519

At March 31, 2018, our investments in real estate partnerships had notes payable of $1.5 billion maturing through 2031, of which 98.5% had a weighted average fixed interest rate of 4.6%. The remaining notes payable float over LIBOR and had a weighted average variable interest rate of 3.3%. These fixed and variable rate notes payable are all non-recourse, and our pro-rata share was $519.5 million as of March 31, 2018. As notes payable mature, we expect they will be repaid from proceeds from new borrowings and/or partner capital contributions.

We believe that our partners are financially sound and have sufficient capital or access thereto to fund future capital requirements. In the event that a co-investment partner was unable to fund its share of the capital requirements of the co-investment partnership, we would have the right, but not the obligation, to loan the defaulting partner the amount of its capital call.

Management fee income

In addition to earning our pro-rata share of net income or loss in each of these co-investment partnerships, we receive fees, as shown below:

Recent Accounting Pronouncements

See note 1 to Consolidated Financial Statements.

Environmental Matters

We are subject to numerous environmental laws and regulations as they apply to our shopping centers pertaining primarily to chemicals used by the dry cleaning industry, the existence of asbestos in older shopping centers, and underground petroleum storage tanks. We believe that the tenants who currently operate dry cleaning plants or gas stations do so in accordance with current laws and regulations. Generally, we use all legal means to cause tenants to remove dry cleaning plants from our shopping centers or convert them to more environmentally friendly systems. Where available, we have applied and been accepted into state-sponsored environmental programs. We have a blanket environmental insurance policy for third-party liabilities and remediation costs on shopping centers that currently have no known environmental contamination. We have also placed environmental insurance, where possible, on specific properties with known contamination, in order to mitigate our environmental risk. We monitor the shopping centers containing environmental issues and in certain cases voluntarily remediate the sites. We also have legal obligations to remediate certain sites and we are in the process of doing so.

52

As of March 31, 2018 we and our Investments in real estate partnerships had accrued liabilities of $9.8 million for our pro-rata share of environmental remediation. We believe that the ultimate disposition of currently known environmental matters will not have a material effect on our financial position, liquidity, or results of operations; however, we can give no assurance that existing environmental studies on our shopping centers have revealed all potential environmental liabilities; that any previous owner, occupant or tenant did not create any material environmental condition not known to us; 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 us.

Inflation/Deflation

Inflation has been historically low and has had a minimal impact on the operating performance of our shopping centers; however, inflation may become a greater concern in the near future. Substantially all of our long-term leases contain provisions designed to mitigate the adverse impact of inflation, which require tenants to pay their pro-rata share of operating expenses, including common-area maintenance, real estate taxes, insurance and utilities, thereby reducing our exposure to increases in costs and operating expenses resulting from inflation. In addition, many of our leases are for terms of less than ten years, which permits us to seek increased rents upon re-rental at market rates. However, during deflationary periods or periods of economic weakness, minimum rents and percentage rents will decline as the supply of available retail space exceeds demand and consumer spending declines. Occupancy declines will result in lower recovery rates of our operating expenses.

There have been no material changes from the quantitative and qualitative disclosures about market risk disclosed in item 7A of Part II of our Form 10-K for the year ended December 31, 2017.

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, and 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.

As of March 31, 2018, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis owned 311 retail shopping centers and held partial interests in an additional 118 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 March 31, 2018, the Parent Company owned approximately 99.8% 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”). 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.

Real Estate Partnerships

As of March 31, 2018, Regency had a partial ownership interest in 129 properties through partnerships, of which 11 are consolidated. Regency's partners include institutional investors, other real estate developers and/or operators, and individual parties who had a role in Regency sourcing 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 the 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 majority of 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.

• 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 Sheets, and Equity in income of investments in real estate partnerships in the Consolidated Statements of Operations. Cash distributions of earnings from operations from 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. Distributed proceeds from debt refinancing and real estate sales in excess of Regency's carrying value of its investment has resulted in a negative investment balance for one partnership, which is recorded within accounts payable and other liabilities in the Consolidated Balance Sheets.

◦ The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is 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.

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.

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)	March 31, 2018		December 31, 2017
Assets
Net real estate investments	$	185,118	172,736
Cash and cash equivalents	4,733		4,993
Liabilities
Notes payable	18,296		16,551
Equity
Limited partners’ interests in consolidated partnerships	17,658		17,572

Revenues and Tenant and Other Receivables

On January 1, 2018, the Company adopted the new accounting guidance for revenue recognition (Topic 606 Revenue from Contracts with Customers, “Topic 606”), as discussed further in the section below, Recent Accounting Pronouncements. Upon adoption of the new standard, certain of the Company's significant accounting policies subject to Topic 606 have been updated.

The Company adopted Topic 606 on January 1, 2018, using a modified retrospective approach and applied the transition practical expedients allowed by the standard.  Additionally, the Company applied the practical expedient related to the remaining performance obligations, because all of its performance obligations are satisfied at a point in time, are part of a contract that has an original expected duration of one year or less, or are considered to be a series of performance obligations where variable consideration is allocated entirely to a wholly unsatisfied distinct day of service that forms part of the series, such that the Company does not need to estimate variable consideration to recognize revenue. 

Subsequent to the adoption of Topic 606, the Company recognizes revenue when or as control of the promised services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The following is a description of the Company's revenue from contracts with customers which is in the scope of Topic 606.

Property and Asset Management Services

The Company is engaged under agreements with its joint venture partnerships, which are generally perpetual in nature and cancellable through unanimous partner approval, absent an event of default. Under these agreements, the Company is to provide asset management, property management, and leasing services for the joint ventures' shopping centers. The fees are market-based, generally calculated as a percentage of either revenues earned or the estimated values of the properties managed or the proceeds received, and are recognized over the monthly or quarterly periods as services are rendered. Property management and asset management services represent a series of distinct daily services under the new revenue standard. Accordingly, the Company satisfies its performance obligation as service is rendered each day and the variability associated with that compensation is resolved each day. Amounts due from the partnerships for such services are paid during the month following the monthly or quarterly service periods.

Several of the Company’s partnership agreements provide for incentive payments, generally referred to as “promotes” or “earnouts,” to Regency for appreciation in property values in Regency's capacity as manager. The terms of these promotes are based on appreciation in real estate value over designated time intervals. The Company evaluates its expected promote payout at each reporting period, which generally does not result in revenue recognition until the measurement period has completed, when the amount can be reasonably determined and the amount is not probable of significant reversal.

Leasing Services

Leasing service fees are based on a percentage of the total rent due under the lease. The leasing service is considered performed upon successful execution of an acceptable tenant lease for the joint ventures’ shopping centers, at which time revenue is recognized. Payment of the first half of the fee is generally due upon lease execution and the second half is generally due upon tenant opening or rent payments commencing.

Transaction Services

The Company also receives transaction fees, as contractually agreed upon with each joint venture, which include acquisition fees, disposition fees, and financing service fees. Control of these services is generally transferred to the customer at the time the related transaction closes, which is the point in time when the Company recognizes the related fees. Any unpaid amounts related to transaction-based fees are included in Accounts receivable.

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, as follows for the three months ended March 31:

(in thousands)	Timing of satisfaction of performance obligations	2018		2017
Property management services	Over time	$	3,768	3,418
Asset management services	Over time	1,703		1,789
Leasing services	Point in time	685		829
Other transaction fees	Point in time	1,002		670
Total management, transaction, and other fees		$	7,158	6,706

The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $9.3 million and $8.7 million, as of March 31, 2018 and December 31, 2017, respectively.

Real Estate Sales

On January 1, 2018, the Company adopted the new accounting guidance for sales of nonfinancial assets (“Subtopic 610-20”), as discussed further in the section below, Recent Accounting Pronouncements. Upon adoption of the new standard, the Company's accounting policy for real estate sales subject to Subtopic 610-20 has been updated. The Company now derecognizes real estate and recognizes a gain or loss on sales of real estate when a contract exists and control of the property has transferred to the buyer. Control of the property, including controlling financial interest, is generally considered to transfer upon closing through transfer of the legal title and possession of the property. Any retained non-controlling interest is measured at fair value. This change in accounting policy resulted in the recognition, through opening retained earnings on January 1, 2018, of $30.9 million of previously deferred gains from property sales to the Company's Investments in real estate partnerships.

Goodwill

Goodwill 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 350, and allocates its goodwill to its reporting units, which have been determined to be at the individual property level. The Company performs an impairment evaluation of its goodwill at least annually, in November of each year, or more frequently as triggers occur.

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 reporting unit’s fair value is less than its carrying value, including goodwill. If a qualitative approach indicates it is more likely-than-not that the estimated carrying value of a reporting unit (including goodwill) exceeds its fair value, or if the Company chooses to bypass the qualitative approach for any reporting unit, the Company will perform the quantitative approach described below.

The quantitative approach consists of estimating the fair value of each reporting unit 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, 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.

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
Other cash payments	721,297
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.

Final 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, and allows a measurement period, not to exceed one year from the acquisition date, to finalize the 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, and deferred taxes related to the book tax difference created through purchase accounting. 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 and the deferred tax liability at one of the acquired taxable REIT subsidiaries. The goodwill is not deductible for tax purposes.

The fair 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 fair value estimates for each of the operating properties acquired, and completed the purchase price allocation during the measurement period, which ended during the three months ended March 31, 2018, resulting in an immaterial adjustment to the purchase price allocation.

The following table summarizes the final 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)	Final Purchase Price Allocation
Land	$	2,865,053

(2)  Weighted average effective and contractual rate for the Line is calculated based on a fully drawn Line balance.

Significant financing activity during 2018 includes:

• On March 9, 2018, the Company received proceeds from issuing $300.0 million of 4.125% senior unsecured public notes, which priced at 99.837% and mature in March 2028. $60 million of the proceeds were used to repay our Line. Subsequent to quarter-end, $163.2 million was used to early redeem, in April 2018, the senior unsecured public notes originally due June 2020. The remainder of the proceeds are intended to be used to repay 2018 mortgage maturities and for general corporate purposes.

• On March 26, 2018, the Company amended and restated its unsecured revolving credit facility (the “Line”). The amendment and restatement increases the size of the Line to $1.25 billion from $1.0 billion and extends the maturity date to March 23, 2022, with options to extend the maturity for two additional six-month periods. Borrowings will bear interest at an annual rate of LIBOR plus 87.5 basis points, subject to the Company’s credit ratings, compared to a rate of 92.5 basis points under its previous facility. An annual facility fee of 15 basis points, subject to the Company’s credit ratings, applies to the entire $1.25 billion Line.    

Subsequent Event

On April 2, 2018, the Company paid $163.2 million, including accrued and unpaid interest through the redemption date and a make-whole amount, to redeem its outstanding $150.0 million 6% Senior Unsecured Notes originally due June 15, 2020. As noted above, the Company used proceeds from its March 9, 2018 offering to fund the redemption.

As of March 31, 2018, scheduled principal payments and maturities on notes payable and unsecured credit facilities were as follows:

(in thousands)	March 31, 2018

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

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		Bank Pays Variable Rate of	Regency Pays Fixed Rate of	March 31, 2018		December 31, 2017
4/3/17	12/2/20	$	300,000	1 Month LIBOR with Floor	1.824%	$	4,690	1,804
8/1/16	1/5/22	265,000		1 Month LIBOR with Floor	1.053%	13,969		10,744
4/7/16	4/1/23	20,000		1 Month LIBOR	1.303%	1,130		801
12/1/16	11/1/23	33,000		1 Month LIBOR	1.490%	1,779		1,166
6/2/17	6/2/27	37,500		1 Month LIBOR with Floor	2.366%	879		(177	)
						$	22,447	14,338
(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 March 31, 2018, 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 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 Accumulated OCI into Income					Total Interest Expense presented in the Consolidated Statements of Operations in which the effects of cash flow hedges are recorded

Interest rate swaps	$	9,505	(68	)	Interest expense	$	2,138	(2,654	)	Interest expense, net	$	36,785	27,199

As of March 31, 2018, the Company expects $4.4 million of net deferred losses on derivative instruments in accumulated other comprehensive income, 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 reclass 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:

	March 31, 2018			December 31, 2017
(in thousands)	Carrying Amount		Fair Value	Carrying Amount		Fair Value
Financial assets:
Notes receivable	$	16,316	16,345	$	15,803	15,660
Financial liabilities:
Notes payable	$	3,276,888	3,291,803	$	2,971,715	3,058,044
Unsecured credit facilities	$	563,380	565,000	$	623,262	625,000

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 March 31, 2018 and December 31, 2017, 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.

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:

During the three months endedMarch 31, 2018, the Company recognized a $15.7 million impairment on an operating property, including $1.4 million for goodwill. The impairment of the real estate, which is classified as held and used as of March 31, 2018, was determined based on the expected selling price as compared to the Company's carrying value of its investment.

There were no assets measured at fair value on a nonrecurring basis as of December 31, 2017.

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.

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 March 31, 2018 and December 31, 2017, the Company had $9.4 million and $9.4 million in letters of credit outstanding, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation, Variable Interest Entity, Policy

Real Estate Partnerships

As of March 31, 2018, Regency had a partial ownership interest in 129 properties through partnerships, of which 11 are consolidated. Regency's partners include institutional investors, other real estate developers and/or operators, and individual parties who had a role in Regency sourcing 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 the 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 majority of 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.

• 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 Sheets, and Equity in income of investments in real estate partnerships in the Consolidated Statements of Operations. Cash distributions of earnings from operations from 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. Distributed proceeds from debt refinancing and real estate sales in excess of Regency's carrying value of its investment has resulted in a negative investment balance for one partnership, which is recorded within accounts payable and other liabilities in the Consolidated Balance Sheets.

◦ The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is 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.

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.

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:

The Company adopted Topic 606 on January 1, 2018, using a modified retrospective approach and applied the transition practical expedients allowed by the standard.  Additionally, the Company applied the practical expedient related to the remaining performance obligations, because all of its performance obligations are satisfied at a point in time, are part of a contract that has an original expected duration of one year or less, or are considered to be a series of performance obligations where variable consideration is allocated entirely to a wholly unsatisfied distinct day of service that forms part of the series, such that the Company does not need to estimate variable consideration to recognize revenue. 

Subsequent to the adoption of Topic 606, the Company recognizes revenue when or as control of the promised services is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. The following is a description of the Company's revenue from contracts with customers which is in the scope of Topic 606.

Property and Asset Management Services

The Company is engaged under agreements with its joint venture partnerships, which are generally perpetual in nature and cancellable through unanimous partner approval, absent an event of default. Under these agreements, the Company is to provide asset management, property management, and leasing services for the joint ventures' shopping centers. The fees are market-based, generally calculated as a percentage of either revenues earned or the estimated values of the properties managed or the proceeds received, and are recognized over the monthly or quarterly periods as services are rendered. Property management and asset management services represent a series of distinct daily services under the new revenue standard. Accordingly, the Company satisfies its performance obligation as service is rendered each day and the variability associated with that compensation is resolved each day. Amounts due from the partnerships for such services are paid during the month following the monthly or quarterly service periods.

Several of the Company’s partnership agreements provide for incentive payments, generally referred to as “promotes” or “earnouts,” to Regency for appreciation in property values in Regency's capacity as manager. The terms of these promotes are based on appreciation in real estate value over designated time intervals. The Company evaluates its expected promote payout at each reporting period, which generally does not result in revenue recognition until the measurement period has completed, when the amount can be reasonably determined and the amount is not probable of significant reversal.

Leasing Services

Leasing service fees are based on a percentage of the total rent due under the lease. The leasing service is considered performed upon successful execution of an acceptable tenant lease for the joint ventures’ shopping centers, at which time revenue is recognized. Payment of the first half of the fee is generally due upon lease execution and the second half is generally due upon tenant opening or rent payments commencing.

Transaction Services

The Company also receives transaction fees, as contractually agreed upon with each joint venture, which include acquisition fees, disposition fees, and financing service fees. Control of these services is generally transferred to the customer at the time the related transaction closes, which is the point in time when the Company recognizes the related fees. Any unpaid amounts related to transaction-based fees are included in Accounts receivable.

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, as follows for the three months ended March 31:

(in thousands)	Timing of satisfaction of performance obligations	2018		2017
Property management services	Over time	$	3,768	3,418
Asset management services	Over time	1,703		1,789
Leasing services	Point in time	685		829
Other transaction fees	Point in time	1,002		670
Total management, transaction, and other fees		$	7,158	6,706

The accounts receivable for management services, which are included within Tenant and other receivables in the accompanying Consolidated Balance Sheets, are $9.3 million and $8.7 million, as of March 31, 2018 and December 31, 2017, respectively.

Real Estate Sales

On January 1, 2018, the Company adopted the new accounting guidance for sales of nonfinancial assets (“Subtopic 610-20”), as discussed further in the section below, Recent Accounting Pronouncements. Upon adoption of the new standard, the Company's accounting policy for real estate sales subject to Subtopic 610-20 has been updated. The Company now derecognizes real estate and recognizes a gain or loss on sales of real estate when a contract exists and control of the property has transferred to the buyer. Control of the property, including controlling financial interest, is generally considered to transfer upon closing through transfer of the legal title and possession of the property. Any retained non-controlling interest is measured at fair value. This change in accounting policy resulted in the recognition, through opening retained earnings on January 1, 2018, of $30.9 million of previously deferred gains from property sales to the Company's Investments in real estate partnerships.

Goodwill and Intangible Assets, Goodwill, Policy

Goodwill

Goodwill 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 350, and allocates its goodwill to its reporting units, which have been determined to be at the individual property level. The Company performs an impairment evaluation of its goodwill at least annually, in November of each year, or more frequently as triggers occur.

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 reporting unit’s fair value is less than its carrying value, including goodwill. If a qualitative approach indicates it is more likely-than-not that the estimated carrying value of a reporting unit (including goodwill) exceeds its fair value, or if the Company chooses to bypass the qualitative approach for any reporting unit, the Company will perform the quantitative approach described below.

The quantitative approach consists of estimating the fair value of each reporting unit 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, 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.

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 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 adopted this ASU on January 1, 2018, using a modified retrospective transition method, which resulted in an immaterial adjustment to opening retained earnings and accumulated other comprehensive income for previously recognized hedge ineffectiveness from off-market hedges.
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.	January 2018	The Company's adoption of this standard did not have a material impact on its results of operations, financialcondition or cash flows as the company has an immaterial amount of equity securities within the scope of this standard. The adoption resulted in reduced disclosure requirements around methodology and significant assumptions used in fair value measurements.
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 adoption of this ASU did not result in a change to the Company's cash flow statement.

Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
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 adoption of this ASU resulted in a change to the classification and presentation of changes in restricted cash on its cash flow statement, which was not material. There was no change to the Company's financial condition or results of operations as a result of adopting this ASU. Upon adoption, and for the three months ended March 31, 2017, net cash provided by operating activities decreased by $67,000 and net cash used in investing activities decreased by $3.4 million, with a corresponding increase in cash and cash equivalents, and restricted cash within the Consolidated Statements of Cash Flows.
ASU 2017-05, February 2017, Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets (Subtopic 610-20)	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 non-controlling 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	Sales of real estate assets are now accounted for under Subtopic 610-20, which provides for revenue recognition based on transfer of control. For normal arms length property sales to unrelated parties, where Regency has no retained interest in the property, the Company will continue to recognize the full gain or loss upon transfer of control. For property sales in which Regency retains a noncontrolling interest in the property, fair value recognition for the retained noncontrolling interest is now required, which will result in full gain recognition upon loss of control. The Company applied the modified retrospective adoption method, and recognized through opening retained earnings $30.9 million of previously deferred gains from property sales to entities in which Regency had continuing involvement, resulting in a corresponding increase to the value of the Company's investment in those partnerships.

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	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 supersedes 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. 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 Company utilized the modified retrospective method of adoption, applying the standard to only 2018, and not restating prior periods presented in future financial statements. The majority of the Company's revenue originates from lease contracts and will be subject to Topic 842 to be adopted in January 2019. Beyond revenue from lease contracts, the Company's primary revenue stream, subject to Topic 606 is Management, transaction, and other fees from the Company's real estate partnerships, primarily in the form of property management services, asset management services, and leasing services. The Company evaluated all partnership service relationships and did not identify any changes in the timing or amount of revenue recognition from these revenue streams. The adoption of Topic 606 resulted in additional disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
Not yet adopted:
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 lease obligations for its ground and office leases with a corresponding right of use asset. The Company will continue to recognize a single lease expense for its existing operating leases, currently included in Operating and maintenance expenses and General and administrative expenses, respectively, in the Consolidated Statements of Operations. Ground leases entered or acquired subsequent to the adoption date will likely be considered finance leases, which will result in a slightly accelerated impact to earnings reflected in amortization expense and interest expense. 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 $1.3 million and $10.4 million during the three months ended March 31, 2018 and the year ended December 31, 2017, respectively. Historic capitalization of legal costs was $0.4 million and $1.2 million during the three months ended March 31, 2018 and the year ended December 31, 2017, respectively, including our pro rata share recognized through Equity in income of investments in real estate partnerships. The Company will continue its evaluation of the accounting standard, additional impacts of adoption, and changes in presentation and disclosure requirements.
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.
