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 currently owns approximately 99.8% of the outstanding common Partnership Units of 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. At December 31, 2011, the Parent Company, the Operating Partnership and their controlled subsidiaries on a consolidated basis (“the Company” or “Regency”) directly owned 217 retail shopping centers and held partial interests in an additional 147 retail shopping centers through 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 carrying values of its investments in real estate including its shopping centers, properties in development and its investments in real estate partnerships, and accounts receivable, net. Although the U.S. economy is recovering, economic conditions remain challenging, and therefore, 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.

Ownership of the Parent Company

The Parent Company has a single class of common stock outstanding and three series of preferred stock outstanding (“Series 3, 4, and 5 Preferred Stock”). The dividends on the Series 3, 4, and 5 Preferred Stock are cumulative and payable in arrears on the last day of each calendar quarter. The Parent Company owns corresponding Series 3, 4, and 5 preferred unit interests (“Series 3, 4, and 5 Preferred Units”) in the Operating Partnership that entitle the Parent Company to income and distributions from the Operating Partnership in amounts equal to the dividends paid on the Parent Company's Series 3, 4, and 5 Preferred Stock.

Ownership of the Operating Partnership

The Operating Partnership's capital includes general and limited common Partnership Units, Series 3, 4, and 5 Preferred Units owned by the Parent Company, and Series D Preferred Units owned by institutional investors. At December 31, 2011, the Parent Company owned approximately 99.8% or 89,921,858 of the total 90,099,022 Partnership Units outstanding.

Net income and distributions of the Operating Partnership are allocable first to the Preferred Units and the remaining amounts to the general and limited common Partnership Units in accordance with their ownership percentages. The Series 3, 4, and 5 Preferred Units owned by the Parent Company are eliminated in consolidation in the accompanying consolidated financial statements of the Parent Company and are classified as preferred units of general partner in the accompanying consolidated financial statements of the Operating Partnership.

Investments in Real Estate Partnerships

Investments in real estate partnerships not controlled by the Company are accounted for under the equity method. The accounting policies of the real estate partnerships are similar to the Company's accounting policies. Income or loss from these real estate partnerships, which includes all operating results (including impairment losses) and gains on sales of properties within the joint ventures, is allocated to the Company in accordance with the respective partnership agreements. Such allocations of net income or loss are recorded in equity in income (loss) of investments in real estate partnerships in the accompanying Consolidated Statements of Operations. 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 (loss) 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, as discussed further below.

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 Company evaluates the structure and the substance of its investments in the real estate partnerships to determine if they are variable interest entities. The Company has concluded that these partnership investments are not variable interest entities. Further, the joint venture partners in the real estate partnerships have significant ownership rights, including approval over operating budgets and strategic plans, capital spending, sale or financing, and admission of new partners. Upon formation of the joint ventures, the Company, through the Operating Partnership, also became the managing member, responsible for the day-to-day operations of the real estate partnerships. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 810, the Company evaluated its investment in each real estate partnership and concluded that the other partners have kick-out rights and/or substantive participating rights and, therefore, the Company has concluded that the equity method of accounting is appropriate for these investments and they do not require consolidation. Under the equity method of accounting, investments in real estate partnerships are initially recorded at cost, subsequently increased for additional contributions and allocations of income, and reduced for distributions received and allocations of loss. These investments are included in the consolidated financial statements as investments in real estate partnerships.

Noncontrolling Interests

The Company consolidates all entities in which it has a controlling ownership interest. A controlling ownership interest is typically attributable to the entity with a majority voting interest. Noncontrolling interest is the portion of equity, in a subsidiary or consolidated entity, not attributable, directly or indirectly to the Company. Such noncontrolling interests are reported on the Consolidated Balance Sheets within equity or capital, but separately from stockholders' equity or partners' capital. On the Consolidated Statements of Operations, all of the revenues and expenses from less-than-wholly-owned consolidated subsidiaries are reported in net income (loss), including both the amounts attributable to the Company and noncontrolling interests. The amounts of consolidated net income (loss) attributable to the Company and to the noncontrolling interests are clearly identified on the accompanying Consolidated Statements of Operations.

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: the preferred units in the Operating Partnership held by third parties (“Series D preferred units”), the limited Partnership Units in the Operating Partnership held by third parties (“Exchangeable operating partnership units”), and 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 (loss) or comprehensive income (loss) attributable to these noncontrolling interests is included in net income (loss) and comprehensive income (loss) in the accompanying Consolidated Statements of Operations and Consolidated Statements of Equity and 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 Preferred Units and exchangeable operating partnership units outstanding and concluded that it has the right to satisfy the redemption requirements of the units by delivering unregistered preferred or common stock. Each outstanding Preferred Unit and exchangeable operating partnership unit is exchangeable for one share of preferred stock or common stock of the Parent Company, respectively, 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 and Comprehensive Income (Loss).

Noncontrolling Interests of the Operating Partnership

The Operating Partnership has determined that Limited partners' interests in consolidated partnerships are noncontrolling interests. 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 and Comprehensive Income (Loss). The portion of net income (loss) or comprehensive income (loss) attributable to these noncontrolling interests is included in net income (loss) and comprehensive income (loss) in the accompanying Consolidated Statements of Operations and Consolidated Statements of Capital and Comprehensive Income (Loss) of the Operating Partnership.

(b) Revenues

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.

During the years ended December 31, 2011, 2010, and 2009, the Company recorded provisions for doubtful accounts of $3.2 million, $4.0 million, and $9.1 million, respectively, of which approximately $91,000, $26,000, and $730,000, respectively, is included in discontinued operations.

The following table represents the components of accounts receivable, net of allowance for doubtful accounts, as of December 31, 2011 and 2010 in the accompanying Consolidated Balance Sheets (in thousands):



		2011		2010
Tenant receivables	$	4,654		19,314
CAM and tax reimbursements		26,355		13,629
Other receivables		10,166		8,476
Less: allowance for doubtful accounts		(3,442	)	(4,819	)
Total	$	37,733		36,600

Substantially 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.

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. When the Company is the owner of the leasehold improvements, recognition of 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 their leasehold improvements.

Profits from sales of real estate are recognized under the full accrual method by the Company when a sale is consummated; the buyer's initial and continuing investment is adequate to demonstrate a commitment to pay for the property; the Company's receivable, if applicable, is not subject to future subordination; the Company has transferred to the buyer the usual risks and rewards of ownership; and 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. The gains and operations associated with properties sold to these real estate partnerships are not classified as discontinued operations because the Company continues to partially own and manage these shopping centers.

As of December 31, 2011, six 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. The liquidation provisions require that all of the properties owned by the real estate partnership be appraised to determine their respective fair values. As a general rule, if the Company initiates the liquidation process, its partner has the right to choose the first property that it will receive with the Company choosing the next property that it will receive in liquidation. If the Company's partner initiates the liquidation process, the order of the selection process is reversed. The process then continues with an alternating selection of properties by each partner until the balance of each partner's capital account, on a fair value basis, has been distributed. After the final selection, to the extent that the fair value of properties in the DIK-JV are not distributable in a manner that equals the balance of each partner's capital account, a cash payment would be made to the other partner by the partner receiving a property distribution in excess of its capital account. The partners may also elect to liquidate some or all of the properties through sales rather than through the DIK process.

The Company has concluded that these DIK dissolution provisions constitute in-substance call/put options and represent a form of continuing involvement with respect to property that the Company has sold to these real estate partnerships, limiting the Company's recognition of gain related to the partial sale. This more restrictive method of gain recognition (“Restricted Gain Method”) considers the Company's potential ability to receive property through a DIK on which partial gain has been recognized, and ensures, as discussed below, maximum gain deferral upon sale to a DIK-JV. The Company has applied the Restricted Gain Method to partial sales of property to real estate partnerships that contain unilateral DIK provisions.

Profit shall be recognized under a method determined by the nature and extent of the seller's continuing involvement and the profit recognized shall be reduced by the maximum exposure to loss. The Company has concluded that the Restricted Gain Method accomplishes this objective.

Under the Restricted Gain Method, for purposes of gain deferral, the Company considers the aggregate pool of properties sold into the DIK-JV as well as the aggregate pool of properties which will be distributed in the DIK process. As a result, upon the sale of properties to a DIK-JV, the Company performs a hypothetical DIK liquidation assuming that it would choose only those properties that it has sold to the DIK-JV in an amount equal to its capital account. For purposes of calculating the gain to be deferred, the Company assumes that it will select properties in a DIK liquidation that would otherwise have generated the highest gain to the Company when originally sold to the DIK-JV. The deferred gain, recorded by the Company upon the sale of a property to a DIK-JV, is calculated whenever a property is sold to a DIK-JV. During the periods when there are no property sales to a DIK-JV, the deferred gain is not recalculated.

Because the contingency associated with the possibility of receiving a particular property back upon liquidation, which forms the basis of the Restricted Gain Method, is not satisfied at the property level, but at the aggregate level, no deferred gain is recognized on 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.

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”.

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 and have not reached their initial full occupancy. In summary, a project changes from non-operating to operating when it is substantially completed and available for occupancy. At that time, costs are no longer capitalized. 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 cost 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.

The following table represents the components of properties in development as of December 31, 2011 and 2010 in the accompanying Consolidated Balance Sheets (in thousands):



		2011	2010
Construction in process	$	50,903	41,611
Construction complete and in lease-up		76,301	459,231
Land held for future development		96,873	110,090
Total	$	224,077	610,932

Construction in process represents developments where the Company has not yet incurred at least 90% of the expected costs to complete and the anchor has not yet been open for at least two calendar years. Construction complete and in lease-up represents developments where the Company has incurred at least 90% of the estimated costs to complete and the anchor has not yet been open for at least two calendar years, but is still completing lease-up and final tenant build out. Land held for future development represents projects not in construction, but identified and available for future development if and when the market demand for a new shopping center exists.

The Company incurs costs 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. These pre-development costs are included in properties in development in the accompanying Consolidated Balance Sheets. At December 31, 2011 and 2010, the Company had capitalized pre-development costs of $2.1 million and $899,000, respectively, of which $1.0 million and $840,000, respectively, were refundable deposits. 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 in other expenses in the accompanying Consolidated Statements of Operations. During the years ended December 31, 2011, 2010, and 2009, the Company expensed pre-development costs of approximately $241,000, $520,000, and $3.8 million, respectively, in other expenses in the accompanying Consolidated Statements of Operations.

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

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.

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, considering the following three categories: (i) value of in-place leases, (ii) above and below-market value of in-place leases, and (iii) customer relationship value.

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 initial 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. 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.

The Company classifies an operating property or a property in development as held-for-sale when it determines that the property is available for immediate sale in its present condition, the property is being actively marketed for sale, and management believes it is probable that a sale will be consummated within one year. Given the nature of all real estate sales contracts, it is not unusual for such contracts to allow prospective buyers a period of time to evaluate the property prior to formal acceptance of the contract. In addition, certain other matters critical to the final sale, such as financing arrangements, often remain pending even upon contract acceptance. As a result, properties under contract may not close within the expected time period, or may not close at all. Therefore, any properties categorized as held-for-sale represent only those properties that management has determined are probable to close within the requirements set forth above. Operating properties held-for-sale are carried at the lower of cost or fair value less costs to sell. The recording of depreciation and amortization expense is suspended during the held-for-sale period. If circumstances arise that previously were considered unlikely and, as a result, the Company decides not to sell a property previously classified as held-for-sale, the property is reclassified as held and used and is measured individually at the lower of its (i) carrying amount before the property was classified as held-for-sale, adjusted for any depreciation and amortization expense that would have been recognized had the property been continuously classified as held and used or (ii) the fair value at the date of the subsequent decision not to sell. Any required adjustment to the carrying amount of the property reclassified as held and used is included in income from continuing operations in the period of the subsequent decision not to sell and the results of operations previously reported in discontinued operations are reclassified and included in income from continuing operations for all periods presented.

When the Company sells a property or classifies a property as held-for-sale and will not have significant continuing involvement in the operation of the property, the operations of the property are eliminated from ongoing operations and classified in discontinued operations. Its operations, including any mortgage interest and gain on sale, are reported in discontinued operations so that the operations are clearly distinguished. Prior periods are also reclassified to reflect the operations of the property as discontinued operations. When the Company sells an operating property to a joint venture or to a third party, and will continue to manage the property, the operations and gain on sale are included in income from continuing operations.

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 highly 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 a significant degree of management judgment and changes in those factors could impact the determination of fair value. In estimating the fair value of undeveloped land, we generally use market data and comparable sales information.

During the years ended December 31, 2011, 2010, and 2009, the Company established a provision for impairment on Consolidated Properties of $15.9 million, $23.9 million, and $103.9 million, respectively, of which $2.1 million and $6.9 million was included in discontinued operations for 2011 and 2009, respectively. There was no impact to discontinued operations in 2010.

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. As a result of this evaluation, the Company established a provision for impairment of $4.6 million on one investment in real estate partnership and $2.7 million on one investment in real estate partnership for the years ended December 31, 2011 and 2010, respectively. No provision for impairment for investments in real estate partnerships was recorded during the year ended December 31, 2009.

The net tax basis of the Company's real estate assets exceeds the book basis by approximately $95.1 million and $71.5 million at December 31, 2011, and 2010, 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. At December 31, 2011 and 2010, $6.0 million and $5.4 million, respectively, of cash was restricted through escrow agreements and certain mortgage loans.

(e) Notes Receivable

The Company records notes receivable at cost on the accompanying Consolidated Balance Sheets and interest income is accrued as earned and netted against interest expense in the accompanying Consolidated Statements of Operations. If a note receivable is past due, meaning the debtor is past due per contractual obligations, the Company ceases to accrue interest. However, in the event the debtor subsequently becomes current, the Company will resume accruing interest and record the interest income accordingly. The Company evaluates the collectibility of both interest and principal for all notes receivable to determine whether impairment exists using the present value of expected cash flows discounted at the note receivable's effective interest rate or, alternatively, at the observable market price of the loan or the fair value of the collateral if the loan is collateral dependent. In the event the Company determines a note receivable or a portion thereof is considered uncollectible, the Company records a provision for impairment. The Company estimates the collectibility of notes receivable taking into consideration the Company's experience in the retail sector, available internal and external credit information, payment history, market and industry trends, and debtor credit-worthiness.

(f) Deferred Costs

Deferred costs include leasing costs and loan costs, net of accumulated amortization. Such costs are amortized over the periods through lease expiration or loan maturity, respectively. If the lease is terminated early, or if the loan is repaid prior to maturity, the remaining leasing costs or loan costs are written off. Deferred leasing costs consist of internal and external commissions associated with leasing the Company's shopping centers. Net deferred leasing costs were $56.5 million and $52.9 million at December 31, 2011 and 2010, respectively. Deferred loan costs consist of initial direct and incremental costs associated with financing activities. Net deferred loan costs were $13.7 million and $10.2 million at December 31, 2011 and 2010, respectively.

(g) Derivative Financial Instruments

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's use of derivative financial instruments is intended to mitigate its interest rate risk on a related financial instrument or forecasted transaction through the use of interest rate swaps (the “Swaps”) and the Company designates these interest rate swaps as cash flow hedges. 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 a gain or loss on derivative instruments. Upon the settlement of a hedge, gains and losses remaining in OCI are amortized 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 settlement of swap terminations is 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 99.8% owner, is allocated its pro-rata share of tax attributes.

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the estimated tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using the enacted tax rates in effect for the year in which these temporary differences are expected to be recovered or settled.

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 (after 2009 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 contribute 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 accounts for stock-based compensation in the same manner as 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; however, 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. In addition, no single tenant accounts for 5% or more of revenue and none of the shopping centers are located outside the United States.

(l) Assets and Liabilities Measured at Fair Value

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.

(m) Recent Accounting Pronouncements

Recently Adopted

In 2010, the Company adopted FASB Accounting Standards Update (“ASU”) No. 2010-06, “Fair Value Measurements and Disclosures (820) - Improving Disclosures about Fair Value Measurements” (“ASU 2010-06”), which requires new disclosures for transfers in and out of Levels 1 and 2 and activity in Level 3 fair value measurements. ASU 2010-06 also clarifies existing disclosure requirements for the level of disaggregation for each class of assets and liabilities and for the inputs and valuation techniques used to measure fair value. In 2011, the Company adopted the deferred provision of ASU 2010-06 relating to disclosures about purchases, sales, issuances, and settlements in the roll forward of activity in Level 3 fair value measurements. The adoption of this ASU had no impact to the Company's consolidated financial statements.

Recently Issued But Not Yet Adopted

In May 2011, the FASB issued ASU No. 2011-04, "Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure requirements in U.S.GAAP and IFRSs" ("ASU 2011-04"). ASU 2011-04 provides new guidance concerning fair value measurements and disclosure. The new guidance is the result of joint efforts by the FASB and the International Accounting Standards Board ("IASB") to develop a single, converged fair value framework on how to measure fair value and the necessary disclosures concerning fair value measurements. The guidance is to be applied prospectively and is effective for interim and annual periods beginning after December 15, 2011. Early adoption is not permitted. The Company does not expect this ASU to have a material effect on the Company's consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, "Comprehensive Income (Topic 220): Presentation of Comprehensive Income" ("ASU 2011-05"). ASU 2011-05 revised guidance over the manner in which entities present comprehensive income in the financial statements. This guidance removes the previous presentation options and provides that entities must report comprehensive income in either a continuous statement of comprehensive income or two separate but consecutive statements. This guidance does not change the items that must be reported in other comprehensive income nor does it require incremental disclosures in addition to those previously required. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. The Company does not expect this ASU to have a material effect on the Company's consolidated financial statements.

(n) Reclassifications and other

Certain reclassifications have been made to the 2010 and 2009 amounts to conform to classifications adopted in 2011. During 2011, the Company has separately disclosed restricted cash on the face of its balance sheet, and has presented the changes in this account, from period to period, in operating cash flows.

- Definition

The entire disclosure for organization, consolidation and basis of presentation of financial statements disclosure.

In addition to the above shopping center acquisitions, on May 4, 2011, the Company entered into an agreement with the DESCO Group ("DESCO") to redeem its entire 16.35% interest in Macquarie CountryWide-Regency-DESCO, LLC ("MCWR-DESCO"). The agreement allowed for a distribution-in-kind ("DIK") of the assets in the co-investment partnership. The assets were distributed as 100% ownership interests to DESCO and to Regency after a selection process, as provided for by the agreement. Regency selected four assets, all in the St. Louis market. The properties which the Company received through the DIK were recorded at the carrying value of the Company's equity investment of $18.8 million. Additionally, as part of the agreement, Regency received a $5.0 million disposition fee at closing on May 4, 2011 to buyout its asset, property, and leasing management contracts, and received $1.0 million for transition services provided through 2011.

The following table provides a summary of shopping centers acquired during the year ended December 31, 2010 (in thousands):

Investments in Real Estate Partnerships

The Company invests in real estate partnerships, which primarily include five co-investment partners and a closed-end real estate fund (“Regency Retail Partners” or the “Fund”). In addition to earning its pro-rata share of net income or loss in each of these real estate partnerships, the Company received recurring market-based fees for asset management, property management, and leasing as well as fees for investment and financing services, of $29.0 million, $25.1 million, and $29.1 million and transaction fees of $5.0 million, $2.6 million, and $7.8 million for the years ended December 31, 2011, 2010, and 2009, respectively.

⁽¹⁾As noted above, effective January 1, 2010, this partnership agreement was amended to include a unilateral right to elect to dissolve the partnership and receive a DIK upon liquidation; therefore, the Company will apply the Restricted Gain Method for additional properties sold to this partnership on or after January 1, 2010. During 2010, the Company did not sell any properties to this real estate partnership.

⁽²⁾As noted above, this partnership agreement has 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 this partnership. During 2010, the Company did not sell any properties to this real estate partnership.

⁽³⁾During March 2010, an amendment was filed with the state of Delaware to change the name of the real estate partnership from Macquarie CountryWide - Regency II, LLC (“MCWR II”) to GRI - Regency, LLC (“GRIR”).

⁽⁴⁾On April 30, 2010, GRIR prepaid $514.8 million of mortgage debt, without penalty, in order to minimize its future refinancing and interest rate risks. The Company contributed capital of $206.7 million to GRIR for its pro-rata share of the repayment funded from its unsecured line of credit and available cash balances. Simultaneously, GRI closed on the purchase of its remaining 15% interest from CHRR, increasing its total ownership in the real estate partnership to 60%. As a part of this transaction, the Company also received a disposition fee of $2.6 million equal to 1% of gross sales price paid by GRI. The Company retained asset management, property management, and leasing responsibilities. On June 2, 2010, GRIR closed on $202.0 million of new ten year secured mortgage loans. The Company received $79.6 million as its pro-rata share of the proceeds. On September 1, 2010, an additional $47.2 million of mortgage debt was repaid, which also required pro-rata contributions from each joint venture partner.

Non-Qualified Deferred Compensation Plan

12 Months Ended

Dec. 31, 2011

Non Qualified Deferred Compensation Plan [Abstract]

Compensation and Employee Benefit Plans [Text Block]

Non-Qualified Deferred Compensation Plan

The Company maintains a non-qualified deferred compensation plan (“NQDCP”). This plan allows select employees and directors to defer part or all of their salary, cash bonus, and restricted stock awards. Restricted stock awards that are designated to be deferred into the NQDCP upon vesting are classified as liabilities from the grant date through the vesting date. All contributions into the participants' accounts are fully vested upon contribution to the NQDCP and are deposited in a Rabbi trust.

The Company accounts for the NQDCP in accordance with FASB Accounting Standards Codification ASC Topic 710 and the restricted stock awards under Topic 718. The assets in the Rabbi trust remain subject to the claims of creditors of the Company and are not the property of the participant. The NQDCP allows participants to allocate their account balance among various investments, including several mutual funds and the Company's common stock. Effective June 20, 2011, the Company amended its NQDCP such that participant account balances held in the Regency common stock fund, including future deferrals of Regency common stock, must remain allocated to the Regency common stock fund and may only be distributed to the participant in the form of Regency common stock upon termination from the plan. Additionally, participant account balances allocated to various diversified mutual funds are prohibited from being allocated into the Regency common stock fund. The assets of the Rabbi trust, exclusive of the shares of the Company's common stock, are classified as trading securities on the accompanying Consolidated Balance Sheets, and accordingly, realized and unrealized gains and losses are recognized within income from deferred compensation plan in the accompanying Consolidated Statements of Operations. Investments in shares of the Company's common stock are included, at cost, as treasury stock in the accompanying Consolidated Balance Sheets of the Parent Company and as a reduction of general partner capital in the accompanying Consolidated Balance Sheets of the Operating Partnership. The participants' deferred compensation liability, exclusive of the shares of the Company's common stock after the June 20, 2011 amendment, is included within accounts payable and other liabilities in the accompanying Consolidated Balance Sheets and was $21.1 million and $35.0 million at December 31, 2011 and December 31, 2010, respectively. Increases or decreases in the deferred compensation liability, exclusive of amounts attributable to participant investments in the shares of the Company's common stock, are recorded as general and administrative expense within the accompanying Consolidated Statements of Operations. Changes in participant account balances related to the Regency common stock fund are recorded directly within stockholders' equity rather than general and administrative expense.

During 2011, the Company determined that it had not properly accounted for the NQDCP or the unvested restricted stock awards which are deferred into the NQDCP in previously filed financial statements. The Company determined it should have been consolidating the assets, liabilities, and activities of the NQDCP and the unvested restricted stock awards which are deferred into the NQDCP should have been treated as liability-classified awards since they previously permitted settlement in assets other than Company stock. The liability-classified awards are included within accounts payable and other liabilities in the accompanying Consolidated Balance Sheet as of December 31, 2010. The Company reviewed the impact of these errors on the prior periods, and determined that the errors were not material. The effect of the correction, in the form of an increase (decrease), on each financial statement line item and per share amounts for each period presented are as follows (in thousands, except per share data):

For 2011, all other items principally represent permanent differences related to impairments and the effect of the change in state tax rate. For 2010, all other items principally represent straight line rents. For 2009, all other items principally represent the permanent differences related to prior year true-ups. Included in the income tax expense (benefit) disclosed above, the Company has approximately $600,000 of state income tax expense at the Operating Partnership for the Texas Gross Margin Tax recorded in other expenses in the accompanying Consolidated Statements of Operations for each of the years ended December 31, 2011, 2010, and 2009.

During 2011, 2010, and 2009, a provision for valuation allowance of $1.4 million, approximately $286,000, and $4.8 million was recorded, respectfully. During 2011, the increase in valuation allowance is due primarily to an increase of $2.0 million for the valuation allowance established related to a property impairment which is not considered recoverable. The 2010 provision for valuation allowance of approximately $286,000 was recorded for 100% of the charitable contribution carryforward. The 2009 provision for valuation allowance of $4.8 million was recorded for 100% of the disallowed interest, under Section 163(j) of the Code.

In all cases, it was determined to be more likely than not that the asset would not be realized. Other deferred tax assets and deferred tax liabilities relate primarily to differences in the timing of the recognition of income or loss between U.S. GAAP and tax basis of accounting. As of December 31, 2011, excluding the provision for valuation allowance, significant portions of the deferred tax assets and deferred tax liabilities include a $4.0 million deferred tax asset for capitalized costs under Section 263A of the Code, a $9.7 million deferred tax asset related to the provision for impairment, an approximately $300,000 deferred tax asset related to a net operating loss (“NOL”) carryforward, and a $2.0 million deferred tax liability related to straight line rents.

As of December 31, 2010, excluding the provision for valuation allowance, significant portions of the deferred tax assets and deferred tax liabilities include a $5.1 million deferred tax asset for capitalized costs under Section 263A of the Code, a $9.0 million deferred tax asset related to the provision for impairment, a $2.7 million deferred tax asset related to a NOL carryforward, and a $1.7 million deferred tax liability related to straight line rents. The Company assessed the components of the net deferred tax asset balance at December 31, 2011 and 2010, excluding the items for which a valuation allowance was provided, and determined that it is more likely than not that the assets will be utilized.

The Company accounts for uncertainties in income tax law in accordance with FASB ASC Topic 740. Under FASB ASC Topic 740, tax positions shall initially be 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 based on an assessment of many factors including past experience and interpretations of tax laws applied to the facts of each matter. Federal and state tax returns are open from 2008 and forward for the Company.

Debt Disclosure [Abstract]

Notes Payable and Unsecured Line of Credit

Notes Payable and Unsecured Credit Facilities

The Parent Company does not have any indebtedness, but guarantees all of the unsecured debt and 12.8% of the secured debt of the Operating Partnership.

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, and mature over various terms through 2028, whereas, interest on unsecured public debt is payable semi-annually and the debt matures over various terms through 2021. Fixed interest rates on mortgage loans range from 5.22% to 8.40% with a weighted average rate of 6.43%. Fixed interest rates on unsecured public debt range from 4.80% to 6.75% with a weighted average rate of 5.59%. As of December 31, 2011, the Company had two variable rate mortgage loans, one in the amount of $3.7 million with a variable interest rate equal to LIBOR plus 380 basis points maturing on October 1, 2014 and one in the amount of $9.0 million with a variable interest rate of LIBOR plus 160 basis points maturing on September 1, 2014.

On January 18, 2011 and December 12, 2011, the Company repaid the maturing balances of $161.7 million of 7.95% and $20 million of 7.25% ten-year unsecured notes, respectively.

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, 2011, management of the Company believes it is in compliance with all financial covenants for its unsecured public debt.

Unsecured Credit Facilities

The Company has a $600.0 million unsecured line of credit (the “Line”) commitment under an agreement (the "Credit Agreement") with Wells Fargo Bank and a syndicate of other banks, which was amended on September 7, 2011 primarily to extend the maturity date to September 2015, and includes one, one year extension option. The Line has a variable interest rate of LIBOR plus 125 basis points and an annual facility fee of 25 basis points subject to Regency maintaining its corporate credit and senior unsecured ratings at BBB. In addition, the Company has the ability to increase the Line through an accordion feature to $1.0 billion. Borrowing capacity is reduced by the balance of outstanding borrowings and commitments under outstanding letters of credit. The balance on the Line was $40.0 million and $10.0 million at December 31, 2011 and 2010, respectively. The proceeds from the Line are used to finance the acquisition and development of real estate and for general working-capital purposes.

The Company is required to comply with certain financial covenants as defined in the Credit Agreement such as Minimum Tangible Net Worth, 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, 2011, management of the Company believes it is in compliance with all financial covenants for the Line.

The Company previously had a $113.8 million revolving credit facility under an agreement with Wells Fargo Bank and a syndicate of other banks that matured in February 2011. There was no balance outstanding at December 31, 2010 and the Company did not renew this facility when it matured in February 2011.

On November 17, 2011, the Company entered into a $250.0 million unsecured term loan (the "Term Loan") commitment under an agreement (the "Term Loan Agreement") with Wells Fargo Bank and a syndicate of other banks, which matures on December 15, 2016. The Term Loan has a variable interest rate of LIBOR plus 145 basis points subject to Regency maintaining its corporate credit and senior unsecured ratings at BBB. In addition, the Company has the ability to increase the Term Loan up to an amount not to exceed an additional $150.0 million subject to the provisions of the Term Loan Agreement. There was no balance outstanding as of December 31, 2011 under the Term Loan.

The Term Loan includes financial covenants relating to minimum tangible net worth, ratio of indebtedness to total asset value, ratio of unsecured indebtedness to unencumbered asset value, ratio of adjusted EBITDA to fixed charges, ratio of secured indebtedness to total asset value, and ratio of unencumbered NOI to unsecured interest expense. The Term Loan also includes customary events of default for agreements of this type (with customary grace periods, as applicable). As of December 31, 2011, management of the Company believes it is in compliance with all financial covenants for its Term Loan.

Derivative Financial Instruments

Dec. 31, 2011

Derivative Financial Instruments [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

Derivative Financial Instruments

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. 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.

Cash Flow Hedges of Interest Rate Risk

The Company's objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount.

The effective portion of changes in the fair value of derivatives designated and qualifying as cash flow hedges is recorded in accumulated other comprehensive loss and subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Such derivatives are used to hedge the variable cash flows associated with forecasted issuances of debt (see “Objectives and Strategies” below for further discussion). The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings as a gain or loss on derivative instruments. During the years ended December 31, 2011, 2010 and 2009, the Company recognized a loss of approximately $54,000, a gain of $1.4 million, and a loss of $3.3 million, respectively, for changes in hedge ineffectiveness attributable to revised inputs used in the valuation models to estimate effectiveness.

On September 29, 2011, the Company entered into the following interest rate swap transaction (in thousands):



Effective Date		Notional Amount	Bank Pays Variable Rate of	Regency Pays Fixed Rate of
October 1, 2011	$	9,000	1 Month LIBOR	0.76	%

This interest rate swap is designated as a cash flow hedge and thus, qualifies for the accounting treatment discussed above.

On October 7, 2010, the Company paid $36.7 million to settle the remaining $140.7 million of interest rate swaps then outstanding. On October 7, 2010, the Company closed on $250.0 million of 4.80% ten-year senior unsecured notes. The Company began amortizing the $36.7 million loss realized from the swap settlement in October 2010 over a ten year period; therefore, the effective interest rate on these notes was 6.26%.

On June 1, 2010, the Company paid $26.8 million to settle and partially settle $150.0 million of its interest rate swaps then outstanding of $290.7 million. On June 2, 2010 the Company also closed on $150.0 million of ten-year senior unsecured notes with an interest rate of 6.00%. The Company began amortizing the $26.8 million loss realized from the swap settlement in June 2010 over a ten year period; therefore, the effective interest rate on these notes was 7.67%.

Realized gains and losses associated with the settled interest rate swaps have been included in accumulated other comprehensive loss in the accompanying Consolidated Statements of Equity and Comprehensive Income (Loss) of the Parent Company and the accompanying Consolidated Statements of Capital and Comprehensive Income (Loss) of the Operating Partnership and are amortized as the corresponding hedged interest payments are made in future periods.

The following table represents the effect of the derivative financial instruments on the accompanying consolidated financial statements for the years ended December 31, 2011, 2010, and 2009 (in thousands):



Derivatives in FASB ASC Topic 815 Cash Flow Hedging Relationships:	Amount of Gain (Loss) Recognized in OCI on Derivative (Effective Portion)					Location of Gain (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)	Amount of Gain (Loss) Reclassified from Accumulated OCI into Income (Effective Portion)							Location of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)	Amount of Gain or (Loss) Recognized in Income on Derivative (Ineffective Portion and Amount Excluded from Effectiveness Testing)

The unamortized balance of the settled interest rate swaps at December 31, 2011 and 2010 was $72.0 million and $81.5 million, respectively, of which the Company expects to amortize $9.5 million during 2012.

The following table represents the fair value of the Company’s derivative financial instruments as well as their classification on the Consolidated Balance Sheets as of December 31, 2011 and 2010 (in thousands):



Liability Derivatives
As of December 31, 2011			As of December 31, 2010
Balance Sheet Location	Fair Value		Balance Sheet Location	Fair Value
Derivative instruments	$	37	Derivative instruments	$	—

Non-designated 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.

Objectives and Strategies

The Company continuously monitors the capital markets and evaluates its ability to issue new debt to repay maturing debt or fund its commitments. Based upon the current capital markets, the Company's current credit ratings, and the number of high quality, unencumbered properties that it owns which could collateralize borrowings, the Company expects that it will successfully issue new secured or unsecured debt to fund its obligations.

The entire disclosure for the entity's entire derivative instruments and hedging activities. Describes an entity's risk management strategies, derivatives in hedging activities and non-hedging derivative instruments, the assets, obligations, liabilities, revenues and expenses arising therefrom, and the amounts of and methodologies and assumptions used in determining the amounts of such items.

Fair Value Disclosures [Abstract]

Fair Value Measurements

(a) Fair Value of Financial Instruments

The following provides information about the methods and assumptions used to estimate the fair value of the Company's financial instruments, including their estimated fair values.

Notes Receivable

The fair value of the Company's notes receivable is estimated based on the current market rates available for notes of the same terms and remaining maturities adjusted for customer specific credit risk. The fair value of notes receivable was determined using Level 3 inputs of the fair value hierarchy. Based on the estimates made by the Company, the fair value of notes receivable was $35.3 million at December 31, 2011.

Trading Securities Held in Trust

The Company has investments in marketable securities 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, considered Level 1 inputs of the fair value hierarchy. The fair value of the trading securities held in trust was $21.7 million and $20.9 million at December 31, 2011 and 2010, respectively. Changes in the value of trading securities are recorded within loss (income) from deferred compensation plan in the accompanying Consolidated Statements of Operations.

Notes Payable

The fair value of the Company's notes payable is estimated based on the current market rates available to the Company for debt of the same terms and remaining 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 including those loans assumed in distribution-in-kind liquidations. The fair value of the notes payable was determined using Level 3 inputs of the fair value hierarchy. Based on the estimates used by the Company, the fair value of notes payable was $2.1 billion at December 31, 2011 and 2010.

Unsecured Line of Credit

The fair value of the Company's Line is estimated based on the interest rates currently offered to the Company by the Company's bankers. Based on the recent amendment to the Line, the Company has determined that fair value approximates carrying value.

Derivative Financial Instruments

The valuation of these instruments 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.

(b) Fair Value Measurements

The following are fair value measurements recorded on a recurring basis as of December 31, 2011 and 2010, respectively (in thousands):



		Fair Value Measurements as of December 31, 2011
December 31, 2011				Quoted Prices in Active Markets for Identical Assets	Significant Other Observable Inputs		Significant Unobservable Inputs
Assets		Balance		(Level 1)	(Level 2)		(Level 3)

Total	$	21,713		21,713	—		—

Trading securities held in trust		20,891	20,891	—	—
Total	$	20,891	20,891	—	—

The following table presents fair value measurements of assets and liabilities that are measured at fair value on a nonrecurring basis at December 31, 2011:



			Quoted Prices in Active Markets for Identical Assets	Significant Other Observable Inputs	Significant Unobservable Inputs	Total Gains (Losses)
Assets		Balance	(Level 1)	(Level 2)	(Level 3)	Total Gains (Losses)
Long-lived assets held and used
Operating and development properties ⁽¹⁾	$	5,520	—	—	5,520	(11,843	)
Investment in real estate partnerships ⁽¹⁾		1,893			1,893	(4,580	)
Total	$	7,413	—	—	7,413	(16,423	)
⁽¹⁾ Represents real estate investments for which the Company has recorded a provision for impairment during 2011.

Long-lived assets held and used are comprised primarily of real estate. The provision for impairment recognized during the year ended December 31, 2011 related to two operating properties. These properties exhibited weak operating fundamentals, including low economic occupancy for an extended period of time, which lead to the impairment. As a result, the Company evaluated the current fair value of the properties and recorded impairment losses.

Fair value was determined through the use of an income approach. The income approach estimates an income stream for a property (typically 10 years) and discounts this income plus a reversion (presumed sale) into a present value at a risk adjusted rate. Yield rates and growth assumptions utilized in this approach are derived from market transactions as well as other financial and industry data. The terminal cap rate and discount rate are significant inputs to this valuation. The Company has determined that the inputs used to value this long-lived asset falls within Level 3 of the fair value hierarchy.

Stock-Based Compensation

12 Months Ended

Dec. 31, 2011

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

Stock-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 for the years ended December 31, 2011, 2010, and 2009 (in thousands):



		2011		2010		2009
Restricted stock	$	10,659		7,236		5,227
Directors' fees paid in common stock		269		231		279
Less: Amount capitalized		(1,104	)	(852	)	(1,574	)
Total	$	9,824		6,615		3,932

The recorded amounts of stock-based compensation expense represent amortization of the grant date fair value of restricted stock awards over the respective vesting periods. Compensation expense specifically identifiable to development and leasing activities is capitalized and included above.

The Company established 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 approximately 4.1 million shares in the form of the Parent Company's common stock or stock options. At December 31, 2011, there were approximately 3.2 million shares available for grant under the Plan either through options or restricted stock.

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.

The following table reports stock option activity during the year ended December 31, 2011:



	Number of Options		Weighted Average Exercise Price	Weighted Average Remaining Contractual Term (in years)		Aggregate Intrinsic Value (in thousands)
Outstanding December 31, 2010	442,880	$	51.85	3.5	$	(4,255	)
Less: Exercised	12,561		35.61
Less: Forfeited	26,754		51.43
Less: Expired	17,416		58.28
Outstanding December 31, 2011	386,149	$	52.12	3.0	$	(5,598	)
Vested and expected to vest - December 31, 2011	386,149	$	52.12	3.0	$	(5,598	)
Exercisable December 31, 2011	386,149	$	52.12	3.0	$	(5,598	)

There were no stock options granted during 2011, 2010, or 2009. The total intrinsic value of options exercised during the years ended December 31, 2011, 2010, and 2009 was approximately $130,000, $1,000, and $40,000, respectively. The Company issues new shares to fulfill option exercises from its authorized shares available.

The following table presents information regarding non-vested option activity during the year ended December 31, 2011:



	Non-vested Number of Options		Weighted Average Grant-Date Fair Value
Non-vested at December 31, 2010	2,185	$	8.78
Less: 2011 Vesting	2,185		8.78
Non-vested at December 31, 2011	—	$	—

The Company grants restricted stock under the Plan to its employees as a form of long-term compensation and retention. The terms of each 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 were valued at the fair market value on the date of grant, earn dividends throughout the vesting period, and have no voting rights. Compensation expense is measured at the grant date and recognized over the vesting period.


•	Time-based awards vest 25% per year beginning on the first anniversary following the grant date. These grants are subject only to continued employment and not dependent on future performance measures; and accordingly, if such vesting criteria are not met, compensation cost previously recognized would be reversed. During 2011, the Company granted 128,139 shares of time-based awards.

•

Performance-based awards are earned subject to future performance measurements, including individual goals, annual growth in earnings, and compounded three-year growth in earnings. Once the performance criteria are achieved and the actual number of shares earned is determined, shares will vest over a required service period. If such performance criteria are not met, compensation cost previously recognized would be reversed. The Company considers the likelihood of meeting the performance criteria based upon managements' estimates from which it determines the amounts recognized as expense on a periodic basis. During 2011, the Company granted 18,246 shares of performance-based awards.

•

Market-based awards are earned dependent upon the Company's total shareholder return in relation to the shareholder return of peer indices over a three-year period (“TSR Grant”). Once the market criteria are met and the actual number of shares earned is determined, 100% of the earned shares vest. The probability of meeting the market criteria is considered when calculating the estimated fair market value on the date of grant using a Monte Carlo simulation. These awards were accounted for as awards with market criteria, with compensation cost recognized over the service period, regardless of whether the market criteria are achieved and the awards are ultimately earned and vest. During 2011, the Company granted 165,689 shares of market-based awards.

The following table reports non-vested restricted stock activity during the year ended December 31, 2011:



	Number of Shares		Intrinsic Value (in thousands)		Weighted Average Grant Price
Non-vested at December 31, 2010	436,559
Add: Time-based awards granted	128,139			$	42.19
Add: Performance-based awards granted	18,246			$	41.54
Add: Market-based awards granted	165,689			$	41.54
Less: Vested and Distributed	173,513			$	43.06
Less: Forfeited	12,861			$	40.31
Non-vested at December 31, 2011	562,259	$	21,152

The weighted-average grant price for restricted stock granted during the years ended December 31, 2011, 2010, and 2009 was $41.81, $35.65, and $38.91, respectively. The total intrinsic value of restricted stock vested during the years ended December 31, 2011, 2010, and 2009 was $7.5 million, $6.1 million, and $9.6 million, respectively.

As of December 31, 2011, there was $13.3 million of unrecognized compensation cost related to non-vested restricted stock granted under the Parent Company's Long-Term Omnibus Plan. When recognized, this compensation results in additional paid in capital in the accompanying Consolidated Statements of Equity and Comprehensive Income (Loss) of the Parent Company and in general partner preferred and common units in the accompanying Consolidated Statements of Capital and Comprehensive Income (Loss) of the Operating Partnership. This unrecognized compensation cost is expected to be recognized over the next three years, through 2014. The Company issues new restricted stock from its authorized shares available at the date of grant.

The Company maintains a 401(k) retirement plan covering substantially all employees, which permits participants to defer up to the maximum allowable amount determined by the IRS of their eligible compensation. This deferred compensation, together with Company matching contributions equal to 100% of employee deferrals up to a maximum of $4,000 of their eligible compensation, is fully vested and funded as of December 31, 2011. Costs related to matching portion of the plan were $1.2 million, $1.1 million, and $1.4 million for the years ended December 31, 2011, 2010, and 2009, respectively.

Thereafter		1,079,349
Total	$	2,467,178

The shopping centers' tenant base includes primarily 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 2058 and in most cases provide for renewal options. 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 2018 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, including capitalized ground lease payments on properties in development, was $9.2 million, $8.1 million and $7.9 million for the years ended December 31, 2011, 2010, and 2009, respectively. The following table summarizes the future obligations under non-cancelable operating leases as of December 31, 2011, (in thousands):

Commitments and Contingencies	Dec. 31, 2011
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. 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 $60.0 million which reduces the credit availability under the Line. The Company also has stand alone letters of credit with other banks. These letters of credit are primarily issued as collateral to facilitate the construction of development projects. As of December 31, 2011 and 2010, the Company had $17.4 million and $5.3 million letters of credit outstanding, respectively.

This element represents the disclosure related to assets and liabilities by class, including [financial] instruments measured at fair value that are classified in stockholders' equity, if any, that are measured at fair value on a recurring and/or nonrecurring basis in periods after initial recognition (for example, impaired assets). The disclosures that may be required or desired include: (a) the fair value measurements recorded during the period and the reasons for the measurements and (b) the level within the fair value hierarchy in which the fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Where the quoted price in an active market for the identical liability is not available, the Level 1 input is the quoted price of an identical liability when traded as an asset.
