Summary of Significant Accounting Policies

Organization and Principles of Consolidation

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 or liabilities other than through its investment in the Operating Partnership. The Parent Company guarantees all of the unsecured debt of the Operating Partnership. As of December 31, 2016, the Parent Company, the Operating Partnership, and their controlled subsidiaries on a consolidated basis (the "Company” or “Regency”) owned 198 retail shopping centers and held partial interests in an additional 109 retail shopping centers through unconsolidated investments in real estate partnerships (also referred to as "joint ventures" or "co-investment partnerships").

Estimates, Risks, and Uncertainties

The preparation of the consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles (“GAAP”) requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The most significant estimates in the Company's financial statements relate to the net carrying values of its real estate investments, accounts receivable, and straight line rent receivable. It is possible that the estimates and assumptions that have been utilized in the preparation of the consolidated financial statements could change significantly if economic conditions were to weaken.

Consolidation

The accompanying consolidated financial statements include the accounts of the Parent Company, the Operating Partnership, its wholly-owned subsidiaries, and consolidated partnerships in which the Company has a controlling interest. Investments in real estate partnerships not controlled by the Company are accounted for under the equity method. All significant inter-company balances and transactions are eliminated in the consolidated financial statements.

The Company consolidates properties that are wholly owned or 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 Parent Company

The Parent Company has a single class of common stock outstanding and two series of preferred stock outstanding (“Series 6 and 7 Preferred Stock”). The dividends on the Series 6 and 7 Preferred Stock are cumulative and payable in arrears quarterly.

Subsequent to December 31, 2016, on February 16, 2017, the Parent Company provided notice of its intent and redeemed all outstanding shares of Series 6 Preferred Stock, as discussed further in note 9.

Ownership of the Operating Partnership

The Operating Partnership's capital includes general and limited common Partnership Units. As of December 31, 2016, the Parent Company owned approximately 99.9% ,or 104,497,286, of the 104,651,456 outstanding common Partnership Units of the Operating Partnership, with the remaining limited Partnership Units held by third parties ("Exchangeable operating partnership units" or "EOP units"). The Parent Company serves as general partner of the Operating Partnership. The EOP unit holders have limited rights over the Operating Partnership such that they do not have the power to direct the activities of the Operating Partnership. As such, the Operating Partnership is considered a variable interest entity, and the Parent Company is the primary beneficiary, which consolidates it. 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

Regency has an ownership interest in 120 properties through partnerships, of which 11 are consolidated. These partners include institutional investors, other real estate developers and/or operators, and individual parties who help Regency source transactions for development and investment (the "Partners" or "limited partners"). Regency has a variable interest in these entities through its equity interests. As managing member, Regency maintains the books and records and typically provides leasing and property management to the partnerships. The Partners’ level of involvement varies from protective decisions (debt, bankruptcy, selling primary asset(s) of business) to involvement in approving leases, operating budgets, and capital budgets.


•	Those partnerships for which the Partners only have protective rights are considered VIEs under ASC 810, Consolidation. Regency is the primary beneficiary of these VIEs as Regency has power over these partnerships and they operate primarily for the benefit of Regency. As such, Regency consolidates these entities and reports the limited partners’ interest as noncontrolling interests.

The 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 Sheet, 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. The net difference in the carrying amount of investments in real estate partnerships and the underlying equity in net assets is either accreted to income and recorded in equity in income of investments in real estate partnerships in the accompanying Consolidated Statements of Operations over the expected useful lives of the properties and other intangible assets, which range in lives from 10 to 40 years, or recognized at liquidation if the joint venture agreement includes a unilateral right to elect to dissolve the real estate partnership and, upon such an election, receive a distribution in-kind.

The assets of 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 these 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)	December 31, 2016		December 31, 2015
Assets
Real estate assets, net	$	86,440	81,424
Cash and cash equivalents	3,444		790
Liabilities
Notes payable	8,175		17,948
Equity
Limited partners’ interests in consolidated partnerships	17,565		11,058

Noncontrolling Interests

Noncontrolling Interests of the Parent Company

The consolidated financial statements of the Parent Company include the following ownership interests held by owners other than the preferred and common stockholders of the Parent Company: (i) the limited Partnership Units in the Operating Partnership held by third parties and (ii) the minority-owned interest held by third parties in consolidated partnerships (“Limited partners' interests in consolidated partnerships”). The Parent Company has included all of these noncontrolling interests in permanent equity, separate from the Parent Company's stockholders' equity, in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity and Comprehensive Income (Loss). The portion of net income or comprehensive income attributable to these noncontrolling interests is included in net income and comprehensive income in the accompanying Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income (Loss) of the Parent Company.

In accordance with the FASB ASC Topic 480, securities that are redeemable for cash or other assets at the option of the holder, not solely within the control of the issuer, are classified as redeemable noncontrolling interests outside of permanent equity in the Consolidated Balance Sheets. The Parent Company has evaluated the conditions as specified under the FASB ASC Topic 480 as it relates to exchangeable operating partnership units outstanding and concluded that it has the right to satisfy the redemption requirements of the units by delivering unregistered common stock. Each outstanding exchangeable operating partnership unit is exchangeable for one share of common stock of the Parent Company, and the unit holder cannot require redemption in cash or other assets. Limited partners' interests in consolidated partnerships are not redeemable by the holders. The Parent Company also evaluated its fiduciary duties to itself, its shareholders, and, as the managing general partner of the Operating Partnership, to the Operating Partnership, and concluded its fiduciary duties are not in conflict with each other or the underlying agreements. Therefore, the Parent Company classifies such units and interests as permanent equity in the accompanying Consolidated Balance Sheets and Consolidated Statements of Equity.

Noncontrolling Interests of the Operating Partnership

The Operating Partnership has determined that limited partners' interests in consolidated partnerships are noncontrolling interests. Subject to certain conditions and pursuant to the terms of the agreement, the Company generally has the right, but not the obligation, to purchase the other member’s interest or sell its own interest in these consolidated partnerships. The Operating Partnership has included these noncontrolling interests in permanent capital, separate from partners' capital, in the accompanying Consolidated Balance Sheets and Consolidated Statements of Capital. The portion of net income (loss) or comprehensive income (loss) attributable to these noncontrolling interests is included in net income and comprehensive income in the accompanying Consolidated Statements of Operations and Consolidated Statements Comprehensive Income (Loss) of the Operating Partnership.

(b) Revenues and Tenant Receivable

Leasing Revenue and Receivables

The Company leases space to tenants under agreements with varying terms. Leases are accounted for as operating leases with minimum rent recognized on a straight-line basis over the term of the lease regardless of when payments are due. The Company estimates the collectibility of the accounts receivable related to base rents, straight-line rents, expense reimbursements, and other revenue taking into consideration the Company's historical write-off experience, tenant credit-worthiness, current economic trends, and remaining lease terms.

The Company recorded the following provisions for doubtful accounts:



	Year ended December 31,
(in thousands)	2016		2015	2014
Gross provision for doubtful accounts	$	1,705	2,364	2,192
Provision for straight line rent reserve	$	2,271	714	107

The following table represents the components of Tenant and other receivables, net in the accompanying Consolidated Balance Sheets:



	December 31,
(in thousands)	2016			2015
Billed tenant receivables	$	15,599		14,521
Accrued CAM, insurance and tax reimbursements	9,221			12,358
Other receivables	12,058			10,708
Straight-line rent receivables	73,384			64,757
Notes receivable	10,481			10,480
Less: allowance for doubtful accounts	(5,460		)	(5,295	)
Less: straight-line rent reserves	(3,561		)	(1,365	)
Total tenant and other receivables, net	$	111,722		106,164

More than half of all of the lease agreements with anchor tenants contain provisions that provide for additional rents based on tenants' sales volume ("percentage rent"). Percentage rents are recognized when the tenants achieve the specified targets as defined in their lease agreements. Substantially all lease agreements contain provisions for reimbursement of the tenants' share of real estate taxes, insurance and common area maintenance (“CAM”) costs. Recovery of real estate taxes, insurance, and CAM costs are recognized as the respective costs are incurred in accordance with the lease agreements.

When the Company is the owner of the leasehold improvements, recognition of straight line lease revenue commences when the lessee is given possession of the leased space upon completion of tenant improvements. However, when the leasehold improvements are owned by the tenant, the lease inception date is the date the tenant obtains possession of the leased space for purposes of constructing its leasehold improvements.

The Notes receivable balance represents a single note from a previous property sale, which has a fixed interest rate of 7.0%, a maturity date of January 2019, and is secured by real estate held as collateral.

Real Estate Sales

Profits from sales of real estate are recognized under the full accrual method by the Company when: (i) a sale is consummated; (ii) the buyer's initial and continuing investment is adequate to demonstrate a commitment to pay for the property; (iii) the Company's receivable, if applicable, is not subject to future subordination; (iv) the Company has transferred to the buyer the usual risks and rewards of ownership; and (v) the Company does not have substantial continuing involvement with the property.

The Company sells shopping centers to joint ventures in exchange for cash equal to the fair value of the ownership interest of its partners. The Company accounts for those sales as “partial sales” and recognizes gains on those partial sales in the period the properties were sold to the extent of the percentage interest sold, and in the case of certain real estate partnerships, applies a more restrictive method of recognizing gains, as discussed further below.

As of December 31, 2016, five of the Company's joint ventures (“DIK-JV”) give each partner the unilateral right to elect to dissolve the real estate partnership and, upon such an election, receive a distribution in-kind (“DIK”) of the assets of the real estate partnership equal to their respective capital account, which could include properties the Company previously sold to the real estate partnership.

Because the contingency associated with the possibility of receiving a particular property back upon liquidation is not satisfied at the property level, but at the aggregate level, no previously deferred gain is recognized by the Company on an individual property sold by the DIK-JV to a third party or received by the Company upon actual dissolution. Instead, the property received upon dissolution is recorded at the carrying value of the Company's investment in the DIK-JV on the date of dissolution. However, the deferred gain is recognized if and when all such properties in the DIK-JV are sold to a third party.

Management Services

The Company is engaged under agreements with its joint venture partners to provide asset management, property management, leasing, investing, and financing services for such 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 as services are rendered, when fees due are determinable, and collectibility is reasonably assured. The Company also receives transaction fees, as contractually agreed upon with a joint venture, which include fees such as acquisition fees, disposition fees, “promotes”, or “earnouts”, which are recognized as services are rendered, when fees due are determinable, and collectibility is reasonably assured.

Capitalization and Depreciation

Maintenance and repairs that do not improve or extend the useful lives of the respective assets are recorded in operating and maintenance expense.

As part of the leasing process, the Company may provide the lessee with an allowance for the construction of leasehold improvements. These leasehold improvements are capitalized and recorded as tenant improvements, and depreciated over the shorter of the useful life of the improvements or the remaining lease term. If the allowance represents a payment for a purpose other than funding leasehold improvements, or in the event the Company is not considered the owner of the improvements, the allowance is considered to be a lease incentive and is recognized over the lease term as a reduction of minimum rent. Factors considered during this evaluation include, among other things, who holds legal title to the improvements as well as other controlling rights provided by the lease agreement and provisions for substantiation of such costs (e.g. unilateral control of the tenant space during the build-out process). Determination of the appropriate accounting for the payment of a tenant allowance is made on a lease-by-lease basis, considering the facts and circumstances of the individual tenant lease.

Depreciation is computed using the straight-line method over estimated useful lives of approximately 40 years for buildings and improvements, the shorter of the useful life or the remaining lease term subject to a maximum of 10 years for tenant improvements, and three to seven years for furniture and equipment.

Development Costs

Land, buildings, and improvements are recorded at cost. All specifically identifiable costs related to development activities are capitalized into properties in development on the accompanying Consolidated Balance Sheets. Properties in development are defined as properties that are in the construction or initial lease-up phase. The capitalized costs include pre-development costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, and allocated direct employee costs incurred during the period of development. Interest costs are capitalized into each development project based upon applying the Company's weighted average borrowing rate to that portion of the actual development costs expended. The Company discontinues interest and real estate tax 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 the Company capitalize interest on the project beyond 12 months after substantial completion of the building shell.

Pre-development costs represent the costs the Company incurs prior to land acquisition including contract deposits, as well as legal, engineering, and other external professional fees related to evaluating the feasibility of developing a shopping center. As of December 31, 2016 and 2015, the Company had refundable deposits of approximately $1.2 million and $1.3 million, respectively, included in pre-development costs. If the Company determines that the development of a particular shopping center is no longer probable, any related pre-development costs previously capitalized are immediately expensed. During the years ended December 31, 2016, 2015, and 2014, the Company expensed pre-development costs of approximately $1.5 million, $1.7 million, and $2.3 million, respectively, in other operating expenses in the accompanying Consolidated Statements of Operations.

Acquisitions

The Company and the real estate partnerships account for business combinations using the acquisition method by recognizing and measuring the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at their acquisition date fair values. The Company expenses transaction costs associated with business combinations in the period incurred.

The Company's methodology includes estimating an “as-if vacant” fair value of the physical property, which includes land, building, and improvements. In addition, the Company determines the estimated fair value of identifiable intangible assets and liabilities, considering the following categories: (i) value of in-place leases, and (ii) above and below-market value of in-place leases.

The value of in-place leases is estimated based on the value associated with the costs avoided in originating leases compared to the acquired in-place leases as well as the value associated with lost rental and recovery revenue during the assumed lease-up period. The value of in-place leases is recorded to amortization expense over the remaining expected term of the respective leases.

Above-market and below-market in-place lease values for acquired properties are recorded based on the present value of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management's estimate of fair market lease rates for comparable in-place leases, measured over a period equal to the remaining non-cancelable term of the lease, including below-market renewal options, if applicable. The value of above-market leases is amortized as a reduction of minimum rent over the remaining terms of the respective leases and the value of below-market leases is accreted to minimum rent over the remaining terms of the respective leases, including below-market renewal options, if applicable. The Company does not assign value to customer relationship intangibles if it has pre-existing business relationships with the major retailers at the acquired property since they do not provide incremental value over the Company's existing relationships.

Held for Sale

The Company classifies land, an operating property, or a property in development as held-for-sale upon satisfaction of the following criteria: (i) management commits to a plan to sell a property (or group of properties), (ii) the property is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such properties, (iii) an active program to locate a buyer and other actions required to complete the plan to sell the property have been initiated, (iv) the sale of the property is probable and transfer of the asset is expected to be completed within one year, (v) the property is being actively marketed for sale, and (vi) actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. Operating properties held-for-sale are carried at the lower of cost or fair value less costs to sell.

Impairment

We evaluate whether there are any indicators, including property operating performance and general market conditions, that the value of the real estate properties (including any related amortizable intangible assets or liabilities) may not be recoverable. Through the evaluation, we compare the current carrying value of the asset to the estimated undiscounted cash flows that are directly associated with the use and ultimate disposition of the asset. Our estimated cash flows are based on several key assumptions, including rental rates, costs of tenant improvements, leasing commissions, anticipated hold period, and assumptions regarding the residual value upon disposition, including the exit capitalization rate. These key assumptions are subjective in nature and could differ materially from actual results. Changes in our disposition strategy or changes in the marketplace may alter the hold period of an asset or asset group which may result in an impairment loss and such loss could be material to the Company's financial condition or operating performance. To the extent that the carrying value of the asset exceeds the estimated undiscounted cash flows, an impairment loss is recognized equal to the excess of carrying value over fair value. If such indicators are not identified, management will not assess the recoverability of a property's carrying value. If a property previously classified as held and used is changed to held-for-sale, the Company estimates fair value, less expected costs to sell, which could cause the Company to determine that the property is impaired.

The fair value of real estate assets is subjective and is determined through comparable sales information and other market data if available, or through use of an income approach such as the direct capitalization method or the traditional discounted cash flow approach. Such cash flow projections consider factors such as expected future operating income, trends and prospects, as well as the effects of demand, competition and other factors, and therefore is subject to management judgment and changes in those factors could impact the determination of fair value. In estimating the fair value of undeveloped land, the Company generally uses market data and comparable sales information.

A loss in value of investments in real estate partnerships under the equity method of accounting, other than a temporary decline, must be recognized in the period in which the loss occurs. If management identifies indicators that the value of the Company's investment in real estate partnerships may be impaired, it evaluates the investment by calculating the fair value of the investment by discounting estimated future cash flows over the expected term of the investment.

Tax Basis

The net tax basis of the Company's real estate assets exceeds the book basis by approximately $190.3 million and $183.9 million at December 31, 2016 and 2015, respectively, primarily due to the property impairments recorded for book purposes and the cost basis of the assets acquired and their carryover basis recorded for tax purposes.

(d) Cash and Cash Equivalents

Any instruments which have an original maturity of 90 days or less when purchased are considered cash equivalents. As of December 31, 2016 and 2015, $4.6 million and $3.8 million, respectively, of cash was restricted through escrow agreements and certain mortgage loans.

(e) Securities

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase and reevaluates such determinations at each balance sheet date. Debt securities are classified as held to maturity when the Company has the positive intent and ability to hold the securities to maturity. Marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses recognized in earnings. Debt and marketable equity securities not classified as held to maturity or as trading, are classified as available-for-sale, and are carried at fair value, with the unrealized gains and losses, net of tax, included in the determination of comprehensive income and reported in the Consolidated Statements of Comprehensive Income. The fair value of securities is determined using quoted market prices.

(f) Deferred Leasing Costs

Deferred leasing costs consist of internal and external commissions associated with leasing the Company's shopping centers, and are presented net of accumulated amortization. Such costs are amortized over the periods through lease expiration or loan maturity, respectively. If the lease is terminated early, the remaining leasing costs are written off.

(g) Derivative Financial Instruments

The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or future payment of known and uncertain cash amounts, the amount of which are determined by interest rates. The Company's derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company's known or expected cash payments principally related to the Company's borrowings.

All derivative instruments, whether designated in hedging relationships or not, are recorded on the accompanying Consolidated Balance Sheets at their fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

The Company uses interest rate swaps to mitigate its interest rate risk on a related financial instrument or forecasted transaction, and the Company designates these interest rate swaps as cash flow hedges. 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 gains or losses resulting from changes in fair value of derivatives that qualify as cash flow hedges are recognized in other comprehensive income (“OCI”) while the ineffective portion of the derivative's change in fair value is recognized in the Statements of Operations as interest expense. Upon the settlement of a hedge, gains and losses remaining in OCI are amortized through earnings over the underlying term of the hedged transaction.

The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking various hedge transactions. The Company assesses, both at inception of the hedge and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in the cash flows and/or forecasted cash flows of the hedged items.

In assessing the valuation of the hedges, the Company uses standard market conventions and techniques such as discounted cash flow analysis, option pricing models, and termination costs at each balance sheet date. All methods of assessing fair value result in a general approximation of value, and such value may never actually be realized.

The cash receipts or payments to settle interest rate swaps are presented in cash flows provided by operating activities in the accompanying Consolidated Statements of Cash Flows.

(h) Income Taxes

The Parent Company believes it qualifies, and intends to continue to qualify, as a REIT under the Internal Revenue Code (the “Code”). As a REIT, the Parent Company will generally not be subject to federal income tax, provided that distributions to its stockholders are at least equal to REIT taxable income. Regency Realty Group, Inc. (“RRG”), a wholly-owned subsidiary of the Operating Partnership, is a Taxable REIT Subsidiary (“TRS”) as defined in Section 856(l) of the Code. RRG is subject to federal and state income taxes and files separate tax returns. As a pass through entity, the Operating Partnership's taxable income or loss is reported by its partners, of which the Parent Company, as general partner and approximately 99.9% owner, is allocated its pro-rata share of tax attributes.

Earnings and profits, which determine the taxability of dividends to stockholders, differs from net income reported for financial reporting purposes primarily because of differences in depreciable lives and cost bases of the shopping centers, as well as other timing differences.

Tax positions are initially recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions shall initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. The Company believes that it has appropriate support for the income tax positions taken and to be taken on its tax returns and that its accruals for tax liabilities are adequate for all open tax years (2013 and forward for federal and state) based on an assessment of many factors including past experience and interpretations of tax laws applied to the facts of each matter.

(i) Earnings per Share and Unit

Basic earnings per share of common stock and unit are computed based upon the weighted average number of common shares and units, respectively, outstanding during the period. Diluted earnings per share and unit reflect the conversion of obligations and the assumed exercises of securities including the effects of shares issuable under the Company's share-based payment arrangements, if dilutive. Dividends paid on the Company's share-based compensation awards are not participating securities as they are forfeitable.

(j) Stock-Based Compensation

The Company grants stock-based compensation to its employees and directors. The Company recognizes stock-based compensation based on the grant-date fair value of the award and the cost of the stock-based compensation is expensed over the vesting period.

When the Parent Company issues common shares as compensation, it receives a like number of common units from the Operating Partnership. The Company is committed to contributing to the Operating Partnership all proceeds from the exercise of stock options or other share-based awards granted under the Parent Company's Long-Term Omnibus Plan (the “Plan”). Accordingly, the Parent Company's ownership in the Operating Partnership will increase based on the amount of proceeds contributed to the Operating Partnership for the common units it receives. As a result of the issuance of common units to the Parent Company for stock-based compensation, the Operating Partnership records the effect of accounts for stock-based compensation for awards of equity in the Parent Company.

(k) Segment Reporting

The Company's business is investing in retail shopping centers through direct ownership or through joint ventures. The Company actively manages its portfolio of retail shopping centers and may from time to time make decisions to sell lower performing properties or developments not meeting its long-term investment objectives. The proceeds from sales are reinvested into higher quality retail shopping centers, through acquisitions or new developments, which management believes will generate sustainable revenue growth and attractive returns. It is management's intent that all retail shopping centers will be owned or developed for investment purposes; however, the Company may decide to sell all or a portion of a development upon completion. The Company's revenues and net income are generated from the operation of its investment portfolio. The Company also earns fees for services provided to manage and lease retail shopping centers owned through joint ventures.

The Company's portfolio is located throughout the United States. Management does not distinguish or group its operations on a geographical basis for purposes of allocating resources or capital. The Company reviews operating and financial data for each property on an individual basis; therefore, the Company defines an operating segment as its individual properties. The individual properties have been aggregated into one reportable segment based upon their similarities with regard to both the nature and economics of the centers, tenants and operational processes, as well as long-term average financial performance.

(l) Business Concentration

No single tenant accounts for 5% or more of revenue and none of the shopping centers are located outside the United States.

(m) Fair Value of Assets and Liabilities

Fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement is determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, the Company uses a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from independent sources (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the Company's own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The three levels of inputs used to measure fair value are as follows:


•	Level 1 - Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access.


•	Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly.


•	Level 3 - Unobservable inputs for the asset or liability, which are typically based on the Company's own assumptions, as there is little, if any, related market activity.

The Company also remeasures nonfinancial assets and nonfinancial liabilities, initially measured at fair value in a business combination or other new basis event, at fair value in subsequent periods if a remeasurement event occurs.

(n) Reclassifications

During the year ended December 31, 2016, the Company reclassified its land held for future development from Properties in development to Land within the accompanying Consolidated Balance Sheets. The Company reclassified prior period amounts of $47.3 million to conform to current period presentation.

⁽¹⁾These partnership agreements have a unilateral right for election to dissolve the partnership and receive a DIK upon liquidation; therefore, the Company has applied the Restricted Gain Method to determine the amount of gain recognized on property sales to these partnerships. During 2016 and 2015, the Company did not sell any properties to these real estate partnerships, and accordingly, the Restricted Gain Method was not applied.

Total notes payable	$	91,396	1,198,900		19,635	1,309,931		469,030

These loans are all non-recourse. Maturities will be repaid from proceeds from refinancing, partner capital contributions, or a combination thereof. The Company is obligated to contribute its pro-rata share to fund maturities if the loans are not refinanced, and it has the capacity to do so from existing cash balances, availability on its line of credit, and operating cash flows. The Company believes that its 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, the Company 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 follows:

Notes Payable

Notes payable consist of mortgage loans secured by properties and unsecured public debt. Mortgage loans may be prepaid, but could be subject to yield maintenance premiums. Mortgage loans are generally due in monthly installments of principal and interest or interest only, whereas, interest on unsecured public debt is payable semi-annually.

The Company is required to comply with certain financial covenants for its unsecured public debt as defined in the indenture agreements such as the following ratios: Consolidated Debt to Consolidated Assets, Consolidated Secured Debt to Consolidated Assets, Consolidated Income for Debt Service to Consolidated Debt Service, and Unencumbered Consolidated Assets to Unsecured Consolidated Debt. As of December 31, 2016, management of the Company believes it is in compliance with all financial covenants for its unsecured public debt.

As of December 31, 2016, the key interest rates of the Company's notes payables were as follows:



		Interest Rates
	Maturing Through	Minimum	Maximum	Weighted Average Effective Rate	Weighted Average Contractual Rate
Mortgage loans	2032	3.30%	8.40%	6.00%	5.80%
Fixed rate unsecured public debt	2025	3.75%	6.00%	5.30%	4.50%

Unsecured Credit Facilities

The Company has an unsecured line of credit commitment (the "Line") and an unsecured term loan commitment (the "Term Loan") under separate credit agreements with a syndicate of banks.

The Company is required to comply with certain financial covenants as defined in the Line and Term Loan credit agreements, such as Ratio of Indebtedness to Total Asset Value ("TAV"), Ratio of Unsecured Indebtedness to Unencumbered Asset Value, Ratio of Adjusted Earnings Before Interest Taxes Depreciation and Amortization (“EBITDA”) to Fixed Charges, Ratio of Secured Indebtedness to TAV, Ratio of Unencumbered Net Operating Income to Unsecured Interest Expense, and other covenants customary with this type of unsecured financing. As of December 31, 2016, management of the Company believes it is in compliance with all financial covenants for the Line and Term Loan.

The key terms of the Line and Term Loan were as follows:



	December 31, 2016

⁽¹⁾The Company has the ability to increase the Line through an accordion feature to $1.0 billion. See discussion below regarding expansion of Line subsequent to December 31, 2016.

⁽²⁾ Borrowing capacity is reduced by the balance of outstanding borrowings and commitments under outstanding letters of credit.

⁽³⁾Maturity is subject to two six month extensions at the Company's option.

⁽⁴⁾The commitment fee is subject to an adjustment based on the higher of the Company's corporate credit ratings from Moody's and S&P.

⁽⁵⁾ Interest rate spread is subject to Regency maintaining its corporate credit and senior unsecured ratings at BBB.

⁽⁶⁾ Effective July 7, 2016, the interest rate on the underlying debt is LIBOR + 0.95%, with an interest rate swap in place to fix the interest on the entire balance at 2% through maturity.

⁽⁷⁾ Annual fee, in thousands.

⁽⁸⁾Weighted average contractual and effective rates for the Line are calculated based on a fully drawn Line balance.

⁽⁹⁾ Weighted average contractual and effective rates for the Term Loan are based on the fixed rate with the interest rate swap.

⁽¹⁾ Includes unsecured public debt and unsecured credit facilities.

The Company has $86.3 million of debt maturing over the next twelve months, which it currently intends to refinance. If market conditions change and refinancing is not an option, the Company has sufficient capacity on its Line to repay the maturing debt, all of which is in the form of non-recourse mortgage loans.

Financing - Subsequent Events

Subsequent to December 31, 2016, the Company priced a public offering of two tranches of senior unsecured notes:

•

$350.0 million of 3.6% notes due February 1, 2027, which priced at 99.741%. The Company intends to use the net proceeds in connection with the consummation of the previously announced pending merger with Equity One, Inc., including (i) to repay approximately $285.0 million in aggregate principal amount of debt of Equity One, and any related interest, fees and expenses and (ii) to pay transaction expenses related to the pending merger with Equity One. In the event that the merger agreement is not consummated, the Company will be required to redeem these notes then outstanding at a redemption price equal to 101% of the principal amount to be redeemed plus accrued and unpaid interest, if any.


•	$300.0 million of 4.4% notes due February 1, 2047, which priced at 99.110%. The Company used a portion of the net proceeds to redeem all of the outstanding shares of its 6.625% Series 6 preferred shares on February 16, 2017 and intends to use the balance to fund investment activities and for general corporate purposes.

In connection with the pending Merger, the Company has commitments to (i) amend its Line by increasing the borrowing capacity to $1.0 billion and (ii) enter a new $300.0 million term loan facility. Both of these transactions are contingent upon the consummation of the Merger and are scheduled to close simultaneously with the Merger. The Company plans to use the proceeds from the new term loan to repay existing term loans held by Equity One. The additional line capacity will accommodate the Company's increased property operations and development / redevelopment programs from the Merger.

⁽¹⁾Represents the date specified in the agreement for either optional or mandatory early termination by the counterparty, which will result in cash settlement. The Company has the option to terminate and settle at any date prior to this.

⁽²⁾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.

⁽³⁾In 2014, the Company entered into $220 million of forward starting interest rate swaps to hedge the interest rate on new fixed rate ten year debt that the Company expected to issue in June 2017 for the specific purpose of repaying at maturity the $300 million notes. These interest rate swaps locked in a weighted average fixed rate of 3.48%, before the Company's credit spread. These swaps were settled during the during the third quarter of 2016, as further described below.

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 currently does not have any derivatives that are not designated as hedges. The Company has master netting agreements, however the Company does not have multiple derivatives subject to a single master netting agreement with the same counterparties. Therefore none are offset in the accompanying Consolidated Balance Sheets.

The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive income (loss) ("AOCI") and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings within interest expense, in the accompanying Consolidated Statements of Operations.

The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements:

As of December 31, 2016, the Company expects $9.8 million of net deferred losses on derivative instruments accumulated in 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.

Hedge Settlement

During the third quarter of 2016, the Company initiated and completed a $400.1 million equity offering, as further described in note 9, for the primary purpose of funding the early redemption of its $300 million notes. The Company also used $40.6 million from the net offering proceeds to settle $220 million of forward starting swaps related to new debt previously expected to be issued in 2017 to repay the notes at maturity. As a result of the equity offering, the Company believed that the issuance of new fixed rate debt within the remaining period of the forward starting swaps was probable not to occur. Accordingly, the Company ceased hedge accounting and reclassified the $40.6 million paid to settle the forward starting swaps from Accumulated other comprehensive loss to earnings during the third quarter of 2016.

Fair Value Measurements

Fair Value Disclosures [Abstract]

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 approximates their fair values, except for the following:



	December 31,
	2016			2015
(in thousands)	Carrying Amount		Fair Value	Carrying Amount		Fair Value
Financial assets:
Notes receivable	$	10,481	10,380	$	10,480	10,620
Financial liabilities:
Notes payable	$	1,363,925	1,435,000	$	1,699,771	1,793,200
Unsecured credit facilities	$	278,495	279,700	$	164,514	165,300

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 December 31, 2016 and 2015. 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, appropriately risk-adjusted discount rates, and available observable and unobservable inputs. Service providers involved in fair value measurements are evaluated for competency and qualifications on an ongoing basis. As considerable judgment is often necessary to estimate the fair value of these financial instruments, the fair values presented above are not necessarily indicative of amounts that will be realized upon disposition of the financial instruments.

The following methods and assumptions were used to estimate the fair value of these financial instruments:

Notes Receivable

The fair value of the Company's notes receivable is estimated by calculating the present value of future contractual cash flows discounted at interest rates available for notes of the same terms and maturities, adjusted for counter-party specific credit risk. The fair value of notes receivable was determined primarily using Level 3 inputs of the fair value hierarchy, which considered counter-party credit risk and collateral risk of the underlying property securing the note receivable.

Notes Payable

The fair value of the Company's unsecured debt is estimated based on the quoted market prices for the same or similar issues or on the current rates offered to the Company for debt of the same remaining maturities. The fair value of the unsecured debt was determined using Level 2 inputs of the fair value hierarchy.

The fair value of the Company's mortgage notes payable is estimated by discounting future cash flows of each instrument at rates that reflect the current market rates available to the Company for debt of the same terms and maturities. Fixed rate loans assumed in connection with real estate acquisitions are recorded in the accompanying consolidated financial statements at fair value at the time the property is acquired. The fair value of the mortgage notes payable was determined using Level 2 inputs of the fair value hierarchy.

Unsecured Credit Facilities

The fair value of the Company's Unsecured credit facilities is estimated based on the interest rates currently offered to the Company by financial institutions. The fair value of the credit facilities was determined using Level 2 inputs of the fair value hierarchy.

The following interest rates were used by the Company to estimate the fair value of its financial instruments:



	December 31,
	2016		2015
	Low	High	Low	High
Notes receivable	7.2%	7.2%	6.3%	6.3%
Notes payable	2.9%	3.9%	2.8%	4.2%
Unsecured credit facilities	1.5%	1.6%	1.1%	1.1%

(b) Fair Value Measurements

The following financial instruments are measured at fair value on a recurring basis:

Trading Securities Held in Trust

The Company has investments in marketable securities, which are assets of the non-qualified deferred compensation plan ("NQDCP"), that are classified as trading securities held in trust on the accompanying Consolidated Balance Sheets. The fair value of the trading securities held in trust was determined using quoted prices in active markets, which are considered Level 1 inputs of the fair value hierarchy. Changes in the value of trading securities are recorded within net investment (income) loss from deferred compensation plan in the accompanying Consolidated Statements of Operations.

Available-for-Sale Securities

Available-for-sale securities consist of investments in certificates of deposit and corporate bonds, and are recorded at fair value using matrix pricing methods to estimate fair value, which are considered Level 2 inputs of the fair value hierarchy. Unrealized gains or losses on these securities are recognized through Other comprehensive income.

Interest Rate Derivatives

The fair value of the Company's interest rate derivatives is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty's nonperformance risk in the fair value measurements.

Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and its counterparties. The Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its interest rate swaps. As a result, the Company determined that its interest rate swaps valuation in its entirety is classified in Level 2 of the fair value hierarchy.

The following table presents 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 December 31, 2016

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock-Based Compensation

tock-Based Compensation

The Company recorded stock-based compensation in general and administrative expenses in the accompanying Consolidated Statements of Operations, the components of which are further described below:



	Year ended December 31,
(in thousands)	2016			2015		2014
Restricted stock ⁽¹⁾	$	13,422		13,869		12,161
Directors' fees paid in common stock ⁽¹⁾	193			200		208
Capitalized stock-based compensation ⁽²⁾	(2,963		)	(2,988	)	(2,707	)
Stock-based compensation, net of capitalization	$	10,652		11,081		9,662

⁽¹⁾Includes amortization of the grant date fair value of restricted stock awards over the respective vesting periods.

⁽²⁾ Includes compensation expense specifically identifiable to development and leasing activities.

The Company established its Long Term Omnibus Plan (the "Plan") under which the Board of Directors may grant stock options and other stock-based awards to officers, directors, and other key employees. The Plan allows the Company to issue up to 4.1 million shares in the form of the Parent Company's common stock or stock options. As of December 31, 2016, there were 2.3 million shares available for grant under the Plan either through stock options or restricted stock.

Stock Option Awards

Stock options are granted under the Plan with an exercise price equal to the Parent Company's stock's price at the date of grant. All stock options granted have ten-year lives, contain vesting terms of one to five years from the date of grant and some have dividend equivalent rights. The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton closed-form (“Black-Scholes”) option valuation model. The Company believes that the use of the Black-Scholes model meets the fair value measurement objectives of FASB ASC Topic 718 and reflects all substantive characteristics of the instruments being valued. There were no stock options granted during the years ended December 31, 2016, 2015 or 2014. There were no stock options exercised, forfeited or expired during the years ended December 31, 2016 or 2015.

The following table summarizes stock options outstanding:



	Year ended December 31, 2016
	Number of Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding as of December 31, 2015	8,741	$	88.45	1.1	$	(178	)
Outstanding as of December 31, 2016	8,741	$	88.45	0.1	$	(170	)
Vested as of December 31, 2016	8,741	$	88.45	0.1	$	(170	)
Exercisable as of December 31, 2016 ⁽¹⁾	8,741	$	88.45	0.1	$	(170	)

⁽¹⁾The Company issues new shares to fulfill option exercises from its authorized shares available. The total intrinsic value of options exercised during the year ended December 31, 2014 was approximately $1.3 million.

Restricted Stock Awards

The Company grants restricted stock under the Plan to its employees as a form of long-term compensation and retention. The terms of each restricted stock grant vary depending upon the participant's responsibilities and position within the Company. The Company's stock grants can be categorized as either time-based awards, performance-based awards, or market-based awards. All awards are valued at fair value, earn dividends throughout the vesting period, and have no voting rights. Fair value is measured using the grant date market price for all time-based or performance-based awards. Market based awards are valued using a Monte Carlo simulation to estimate the fair value based on the probability of satisfying the market conditions and the projected stock price at the time of payout, discounted to the valuation date over a three year performance period. Assumptions include historic volatility over the previous three year period, risk-free interest rates, and Regency's historic daily return as compared to the market index. Since the award payout includes dividend equivalents and the total shareholder return includes the value of dividends, no dividend yield assumption is required for the valuation. Compensation expense is measured at the grant date and recognized on a straight-line basis over the requisite vesting period for the entire award.

The following table summarizes non-vested restricted stock activity:



	Year ended December 31, 2016
	Number of Shares	Intrinsic Value (in thousands)	Weighted Average Grant Price
Non-vested as of December 31, 2015	615,420
Add: Time-based awards granted^{(1) (4)}	117,275		$73.22
Add: Performance-based awards granted ^{(2) (4)}	6,521		$73.22
Add: Market-based awards granted ^{(3) (4)}	67,332		$90.49
Less: Vested and Distributed ⁽⁵⁾	222,915		$70.27
Less: Forfeited	22,372		$60.53
Non-vested as of December 31, 2016 ⁽⁶⁾	561,261	$39,699

⁽¹⁾Time-based awards vest beginning on the first anniversary following the grant date over a three or four year service period. These grants are subject only to continued employment and are not dependent on future performance measures. Accordingly, if such vesting criteria are not met, compensation cost previously recognized would be reversed.

⁽²⁾ Performance-based awards are earned subject to future performance measurements. Once the performance criteria are achieved and the actual number of shares earned is determined, shares vest over a required service period. The Company considers the likelihood of meeting the performance criteria based upon management's estimates from which it determines the amounts recognized as expense on a periodic basis.

⁽³⁾Market-based awards are earned dependent upon the Company's total shareholder return in relation to the shareholder return of a NAREIT index over a three-year period. Once the performance criteria are met and the actual number of shares earned is determined, the shares are immediately vested and distributed. The probability of meeting the criteria is considered when calculating the estimated fair value on the date of grant using a Monte Carlo simulation. These awards are accounted for as awards with market criteria, with compensation cost recognized over the service period, regardless of whether the performance criteria are achieved and the awards are ultimately earned. The significant assumptions underlying determination of fair values for market-based awards granted were as follows:

⁽⁴⁾The weighted-average grant price for restricted stock granted during the years ended December 31, 2016, 2015, and 2014 was $79.40, $69.80, and $48.18, respectively.

⁽⁵⁾The total intrinsic value of restricted stock vested during the years ended December 31, 2016, 2015, and 2014 was $15.4 million, $18.6 million, and $12.4 million, respectively.

⁽⁶⁾ As of December 31, 2016, there was $12.8 million of unrecognized compensation cost related to non-vested restricted stock granted under the Parent Company's Plan. When recognized, this compensation results in additional paid in capital in the accompanying Consolidated Statements of Equity of the Parent Company and in general partner preferred and common units in the accompanying Consolidated Statements of Capital of the Operating Partnership. This unrecognized compensation cost is expected to be recognized over the next three years. The Company issues new restricted stock from its authorized shares available at the date of grant.

Leases greater than 10,000 square feet generally have lease terms in excess of five years, mostly comprised of anchor tenants. Many of the anchor leases contain provisions allowing the tenant the option of extending the term of the lease at expiration. Future minimum rents under non-cancelable operating leases as of December 31, 2016, excluding both tenant reimbursements of operating expenses and additional percentage rent based on tenants' sales, are as follows:



In Process Year Ending December 31,	Future Minimum Rents (in thousands)
2017	$	434,070
2018	390,872
2019	346,356
2020	295,289
2021	241,549
Thereafter	990,609
Total	$	2,698,745

The shopping centers' tenant base primarily includes national and regional supermarkets, drug stores, discount department stores, and other retailers and, consequently, the credit risk is concentrated in the retail industry. There were no tenants that individually represented more than 5% of the Company's annualized future minimum rents.

The Company has shopping centers that are subject to non-cancelable, long-term ground leases where a third party owns and has leased the underlying land to the Company to construct and/or operate a shopping center. Ground leases expire through the year 2101, and in most cases, provide for renewal options. Buildings and improvements constructed on the leased land are capitalized and depreciated over the shorter of the useful life of the improvements or the lease term.

In addition, the Company has non-cancelable operating leases pertaining to office space from which it conducts its business. Office leases expire through the year 2027, and in most cases, provide for renewal options. Leasehold improvements are capitalized, recorded as tenant improvements, and depreciated over the shorter of the useful life of the improvements or the lease term.

Operating lease expense was $13.1 million, $9.5 million, and $8.9 million for the years ended December 31, 2016, 2015, and 2014, respectively. The following table summarizes the future obligations under non-cancelable operating leases as of December 31, 2016:

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The Company is involved in litigation on a number of matters and is subject to certain claims, which arise in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. Legal fees are expensed as incurred. After the announcement of the merger agreement on November 14, 2016, a putative class action was filed on behalf of a purported stockholder in the Circuit Court for Duval County, Florida, under the following caption: Robert Garfield on Behalf of Himself and All Others Similarly Situated vs. Regency Centers Corporation, Martin E. Stein, Jr., John C. Schweitzer, Raymond L. Bank, Bryce Blair, C. Ronald Blankenship, J. Dix Druce, Jr., Mary Lou Fiala, David P. O'Connor, and Thomas G. Wattles, No. 16-2017-CA-000688-XXXX-MA, filed February 3, 2017. The class action alleges, among other matters, that the definitive joint proxy statement/prospectus filed by Regency and Equity One with the Securities and Exchange Commission (the “SEC”) on January 24, 2017 (the “Joint Proxy Statement/Prospectus”) omitted certain material information in connection with the Merger. The complainant seeks various remedies, including injunctive relief to prevent the consummation of the Merger unless certain allegedly material information is disclosed and seeking compensatory and rescissory damages in the event the Merger is consummated without such disclosures. On February 17, 2017, the defendants entered into a stipulation of settlement with respect to the class action, pursuant to which the parties have agreed, among other things, that Regency will make certain supplemental disclosures. The supplemental disclosures were made by Regency in the Current Report on Form 8-K filed by Regency with the SEC on February 17, 2017. The supplemental disclosures should be read in conjunction with the Joint Proxy Statement/Prospectus, which should be read in its entirety. Regency believes that the class action is without merit and that no supplemental disclosure is required to the Joint Proxy Statement/Prospectus under any applicable rule, statute, regulation or law. However, to, among other things, eliminate the burden, inconvenience, expense, risk and disruption of further litigation, Regency has determined that it will provide supplemental disclosures. Additional information regarding the stipulation of settlement or additional disclosures may be found in the Current Report on Form 8-K as filed with the SEC on February 17, 2017. 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; however, it can give no assurance that existing environmental studies with respect to the 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 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. 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 to facilitate the construction of development projects. As of December 31, 2016 and 2015, the Company had $5.8 million and $5.9 million in letters of credit outstanding

Subsequent Event [Line Items]
Subsequent Events [Text Block]	16. Subsequent Events Approval of Merger with Equity One, Inc. On November 14, 2016, Regency entered into a Merger Agreement with Equity One, pursuant to which, subject to the satisfaction or waiver of certain conditions, Equity One will merge with and into the Company, with Regency being the surviving corporation (the “Merger”). The combined company will retain the Regency name and will continue to trade under the ticker symbol REG on the New York Stock Exchange ("NYSE"). The Company will expand its board of directors to 12 directors and will add three persons who served on Equity One's board of directors. The executive officers of Regency immediately prior to the effective date of the merger will continue to serve as executive officers of the combined company. On the terms and subject to the conditions set forth in the Merger Agreement, which has been unanimously approved by the boards of directors of the Company and Equity One, at the effective time of the Merger, each share of the common stock, par value $0.01 per share, of Equity One issued and outstanding immediately prior to the effective time (other than shares of Equity One owned directly by Equity One or the Company and in each case not held on behalf of third parties) will be converted into the right to receive 0.45 of a newly issued share of the common stock of the Company. The consummation of the Merger is subject to certain closing conditions, including (i) the approval of the Company’s and Equity One’s respective stockholders, (ii) the shares of Company Common Stock to be issued in the Merger will have been approved for listing on the New York Stock Exchange, subject to official notice of issuance, (iii) the absence of any temporary restraining order, preliminary or permanent injunction or other order issued by any court of competent jurisdiction or other legal restraint or prohibition preventing the consummation of the Merger, (iv) the receipt of certain tax opinions by the Company and Equity One, and (v) other customary conditions specified in the Merger Agreement. At a special meeting of Regency stockholders, held on Friday, February 24, 2017, the stockholders approved all matters subject to stockholder vote, including (i) the proposed Merger Agreement and the Merger, (ii) the proposal to amend the Restated Articles of Incorporation of Regency to increase the number of authorized shares of Regency common stock, and (iii) the proposal to increase the size of the Regency board of directors to 12 directors. At a separate special meeting of Equity One stockholders, also held on Friday, February 24, 2017, their stockholders approved all matters subject to stockholder vote, including (i) the proposed Merger Agreement and the Merger, and (ii) the proposal to approve the compensation that may be paid or become payable to the named executive officers in connection with the Merger. The Merger is expected to close effective March 1, 2017, at which time each share of Equity One common stock issued and outstanding will be converted into the right to receive 0.45 of a newly issued share of Regency common stock. The merger will be accounted for using the acquisition method of accounting. The purchase price will be computed using the closing price of Regency common stock on the closing date applied to the number of shares of common stock issued to consummate the merger. Under the acquisition method of accounting, the total purchase price is allocated to the acquired net tangible and identifiable intangible assets and liabilities assumed of Equity One based on their respective fair values, on the closing date. Since the purchase price will be based on the price of Regency's common stock on the effective date, the purchase price and resulting purchase price allocation is not yet known. Further information about preliminary estimated purchase price and unaudited pro forma financial statements of the combined company can be found in the Form S-4, as filed with the Securities and Exchange Commission on December 22, 2016 and subsequent amendments thereto. After the announcement of the merger agreement on November 14, 2016, a putative class action was filed on behalf of a purported stockholder in the Circuit Court for Duval County, Florida, under the following caption: Robert Garfield on Behalf of Himself and All Others Similarly Situated vs. Regency Centers Corporation, Martin E.

Wattles, No. 16-2017-CA-000688-XXXX-MA, filed February 3, 2017. The class action alleges, among other matters, that the definitive joint proxy statement/prospectus filed by Regency and Equity One with the Securities and Exchange Commission (the “SEC”) on January 24, 2017 (the “Joint Proxy Statement/Prospectus”) omitted certain material information in connection with the Merger.

However, to, among other things, eliminate the burden, inconvenience, expense, risk and disruption of further litigation, Regency has determined to provide supplemental disclosures. Additional information regarding the stipulation of settlement may be found in the Current Report on Form 8-K as filed with the SEC on February 17, 2017.

Recent Accounting Pronouncements

(o) 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 2015-02, February 2015, Consolidation (Topic 810): Amendments to the Consolidation Analysis	ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the consolidation analysis of reporting entities that are involved with VIEs.	January 2016	The adoption of this standard resulted in five additional investment partnerships being considered variable interest entities due to the limited partners' lack of substantive participation in the partnerships. This did not result in any impact to the Company's Consolidated Balance Sheets, Statements of Operations, or Cash Flows, but did result in additional disclosures about its relationships with and exposure to variable interest entities.

ASU 2015-03, April 2015, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs	ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.	January 2016	The adoption and implementation of this standard has resulted in the retrospective presentation of debt issuance costs associated with the Company's notes payable and term loans as a direct deduction from the carrying amount of the related debt instruments (previously, included in deferred costs in the consolidated balance sheets). Unamortized debt issuance costs of $8.2 million has been reclassified to offset the related debt as of December 31, 2015.

ASU 2015-15, August 2015, Interest—Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements	ASU 2015-15 clarifies that debt issuance costs related to line-of-credit arrangements may be deferred and presented as an asset, amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings.	January 2016	The adoption of this standard resulted in the continued presentation of debt issuance costs related to the Line of credit ("Line") as an asset in the Consolidated Balance Sheets, previously within deferred costs, and now presented within other assets.

ASU 2014-15, August 2014, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern	The standard requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued.	December 2016	The adoption of this standard did not have an impact on the Company's Consolidated Balance Sheets, Statements of Operations, or Cash Flows but did result in more disclosure surrounding the Company's plans for addressing significant upcoming debt maturities.



Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
Not yet adopted:
ASU 2016-09, March 2016, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, an option to recognize stock compensation forfeitures as they occur, and changes to classification on the statement of cash flows.	January 2017	The Company does not expect the adoption of this standard to have an impact on its financial statements and related disclosures.

ASU 2016-01, January 2016, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities	The standard amends the guidance to classify equity securities with readily-determinable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Equity investments accounted for under the equity method are not included in the scope of this amendment. Early adoption of this amendment is not permitted.	January 2018	The Company does not expect the adoption and implementation of this standard to have a material impact on its results of operations, financial condition or cash flows.

ASU 2016-15, August 2016, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments	The standard makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Early adoption is permitted on a retrospective basis.	January 2018	The ASU is consistent with the Company's current treatment and the Company does not expect the adoption and implementation of this standard to have an impact on its cash flow statement.

ASU 2016-18, November 2016, Statement of Cash Flows (Topic 230): Restricted Cash	This ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. Early adoption is permitted on a retrospective basis.	January 2018	The Company is currently evaluating the alternative methods of adoption and does not expect the adoption to have a material impact on its Statements of Cash Flows.

ASU 2017-01 January 2017, Business Combinations (Topic 805): Clarifying the Definition of a Business	The amendments in this update provide a screen to determine when an integrated set of assets and activities, collectively referred to as a "set", is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. Early adoption is permitted.	January 2018	The Company is currently evaluating the amendments from this Update, but expects it to change the treatment of individual operating properties from being considered a business to being considered an asset. This change will result in acquisition costs being capitalized as part of the asset acquisition, whereas current treatment has them recognized in earnings in the period incurred. Additional changes from the Update are still being evaluated to identify their impact to the Company's financial statements and related disclosures.



Standard	Description	Date of adoption	Effect on the financial statements or other significant matters

ASU 2016-02, February 2016, Leases (Topic 842)	The standard 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 initial direct leasing costs, which no longer considers fixed internal leasing salaries as capitalizable costs. 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 currently evaluating the impact this standard will have on its financial statements and related disclosures.

ASU 2016-13, June 2016, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU applies to how the Company determines its allowance for doubtful accounts on tenant receivables.	January 2020	The Company is currently evaluating the alternative methods of adoption and the impact the ASU will have on its financial statements and related disclosures.

- Definition

Tabular disclosure of the significant judgments and assumptions made in determining whether a variable interest (as defined) held by the entity requires the variable interest entity (VIE) (as defined) to be consolidated and (or) disclose information about its involvement with the VIE, individually or in aggregate (as applicable); the nature of restrictions, if any, on the consolidated VIE's assets and on the settlement of its liabilities reported by an entity in its statement of financial position, including the carrying amounts of such assets and liabilities; the nature of, and changes in, the risks associated with involvement in the VIE; how involvement with the VIE affects the entity's financial position, financial performance, and cash flows; the lack of recourse if creditors (or beneficial interest holders) of the consolidated VIE have no recourse to the general credit of the primary beneficiary (if applicable); the terms of arrangements, giving consideration to both explicit arrangements and implicit variable interests, if any, that could require the entity to provide financial support to the VIE, including events or circumstances that could expose the entity to a loss; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; the significant factors considered and judgments made in determining that the power to direct the activities of a VIE that most significantly impact the VIE's economic performance are shared (as defined); the carrying amounts and classification of assets and liabilities of the VIE included in the statement of financial position; the entity's maximum exposure to loss, if any, as a result of its involvement with the VIE, including how the maximum exposure is determined and significant sources of the entity's exposure to the VIE; a comparison of the carrying amounts of the assets and liabilities and the entity's maximum exposure to loss; information about any liquidity arrangements, guarantees, and (or) other commitments by third parties that may affect the fair value or risk of the entity's variable interest in the VIE; whether or not the entity has provided financial support or other support (explicitly or implicitly) to the VIE that it was not previously contractually required to provide or whether the entity intends to provide that support, including the type and amount of the support and the primary reasons for providing the support; and supplemental information the entity determines necessary to provide.

Schedule of New Accounting Pronouncements and Changes in Accounting Principles [Table Text Block]

(o) 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 2015-02, February 2015, Consolidation (Topic 810): Amendments to the Consolidation Analysis	ASU 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 modifies the evaluation of whether limited partnerships and similar legal entities are VIEs or voting interest entities, eliminates the presumption that a general partner should consolidate a limited partnership, and affects the consolidation analysis of reporting entities that are involved with VIEs.	January 2016	The adoption of this standard resulted in five additional investment partnerships being considered variable interest entities due to the limited partners' lack of substantive participation in the partnerships. This did not result in any impact to the Company's Consolidated Balance Sheets, Statements of Operations, or Cash Flows, but did result in additional disclosures about its relationships with and exposure to variable interest entities.

ASU 2015-03, April 2015, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs	ASU 2015-03 simplifies the presentation of debt issuance costs by requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts.	January 2016	The adoption and implementation of this standard has resulted in the retrospective presentation of debt issuance costs associated with the Company's notes payable and term loans as a direct deduction from the carrying amount of the related debt instruments (previously, included in deferred costs in the consolidated balance sheets). Unamortized debt issuance costs of $8.2 million has been reclassified to offset the related debt as of December 31, 2015.

ASU 2015-15, August 2015, Interest—Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements	ASU 2015-15 clarifies that debt issuance costs related to line-of-credit arrangements may be deferred and presented as an asset, amortized over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings.	January 2016	The adoption of this standard resulted in the continued presentation of debt issuance costs related to the Line of credit ("Line") as an asset in the Consolidated Balance Sheets, previously within deferred costs, and now presented within other assets.

ASU 2014-15, August 2014, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern	The standard requires management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, and to provide certain disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued.	December 2016	The adoption of this standard did not have an impact on the Company's Consolidated Balance Sheets, Statements of Operations, or Cash Flows but did result in more disclosure surrounding the Company's plans for addressing significant upcoming debt maturities.



Standard	Description	Date of adoption	Effect on the financial statements or other significant matters
Not yet adopted:
ASU 2016-09, March 2016, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities, an option to recognize stock compensation forfeitures as they occur, and changes to classification on the statement of cash flows.	January 2017	The Company does not expect the adoption of this standard to have an impact on its financial statements and related disclosures.

ASU 2016-01, January 2016, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities	The standard amends the guidance to classify equity securities with readily-determinable fair values into different categories and requires equity securities to be measured at fair value with changes in the fair value recognized through net income. Equity investments accounted for under the equity method are not included in the scope of this amendment. Early adoption of this amendment is not permitted.	January 2018	The Company does not expect the adoption and implementation of this standard to have a material impact on its results of operations, financial condition or cash flows.

ASU 2016-15, August 2016, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments	The standard makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. Early adoption is permitted on a retrospective basis.	January 2018	The ASU is consistent with the Company's current treatment and the Company does not expect the adoption and implementation of this standard to have an impact on its cash flow statement.

ASU 2016-18, November 2016, Statement of Cash Flows (Topic 230): Restricted Cash	This ASU requires entities to show the changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents in the statement of cash flows. Early adoption is permitted on a retrospective basis.	January 2018	The Company is currently evaluating the alternative methods of adoption and does not expect the adoption to have a material impact on its Statements of Cash Flows.

ASU 2017-01 January 2017, Business Combinations (Topic 805): Clarifying the Definition of a Business	The amendments in this update provide a screen to determine when an integrated set of assets and activities, collectively referred to as a "set", is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. Early adoption is permitted.	January 2018	The Company is currently evaluating the amendments from this Update, but expects it to change the treatment of individual operating properties from being considered a business to being considered an asset. This change will result in acquisition costs being capitalized as part of the asset acquisition, whereas current treatment has them recognized in earnings in the period incurred. Additional changes from the Update are still being evaluated to identify their impact to the Company's financial statements and related disclosures.



Standard	Description	Date of adoption	Effect on the financial statements or other significant matters

ASU 2016-02, February 2016, Leases (Topic 842)	The standard 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 initial direct leasing costs, which no longer considers fixed internal leasing salaries as capitalizable costs. 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 currently evaluating the impact this standard will have on its financial statements and related disclosures.

ASU 2016-13, June 2016, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments	The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU applies to how the Company determines its allowance for doubtful accounts on tenant receivables.	January 2020	The Company is currently evaluating the alternative methods of adoption and the impact the ASU will have on its financial statements and related disclosures.
