	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. As of September 30, 2013, the Parent Company, the Operating Partnership and their controlled subsidiaries on a consolidated basis (the "Company” or “Regency”) directly owned 202 retail shopping centers and held partial interests in an additional 131 retail shopping centers through investments in real estate partnerships (also referred to as "joint ventures" or "co-investment partnerships").
	The financial statements reflect all adjustments which are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented. These adjustments are considered to be of a normal recurring nature.
	Recently Adopted Accounting Pronouncements
	On January 1, 2013, the Company adopted Financial Accounting Standards Board ("FASB") Accounting Standards Update (“ASU”) No. 2011-11, Disclosures about Offsetting Assets and Liabilities ("ASU 2011-11") and ASU No. 2013-01, Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities. These new standards retain the existing offsetting models under U.S. GAAP but require new disclosure requirements for derivatives, including bifurcated embedded derivatives, repurchase and reverse repurchase agreements, and securities lending transactions that are either offset in the Consolidated Balance Sheets or subject to an enforceable master netting arrangement or similar agreement. Retrospective application is required. While the Company does have master netting agreements, it does not have multiple derivatives with the same counterparties subject to a single master netting agreement to offset, therefore no additional disclosures are necessary.

The assets of the partnership were distributed as 100% ownership interests to CQR and Regency after a selection process, as provided for by the partnership agreement. Regency selected one asset, Hilltop Village, which was recorded at the carrying value of the Company's equity investment in MCWR III, net of deferred gain, on the date of dissolution of $7.6 million, including a $7.5 million mortgage assumed.

(1) Represents the date specified in the agreement for either optional or mandatory early termination which will result in cash settlement.

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 Sheet.

The Company has $150.0 million of unsecured long-term debt that matures in 2014 and $350.0 million of unsecured long-term debt that matures in 2015. In order to mitigate the risk of interest rates rising before new unsecured borrowings are obtained, the Company entered into five forward-starting interest rate swaps during December 2012, for the same ten year periods expected for the future borrowings. These swaps total $300.0 million of notional value, as shown above. The Company will settle these swaps upon the early termination date, which is expected to coincide with the date new unsecured borrowings are obtained, and will begin amortizing the gain or loss realized from the swap settlement over the ten year period expected for the new borrowings; resulting in a modified effective interest rate on those borrowings. In October 2013, the Company entered into two additional forward-starting interest rate swaps for $95.0 million of notional value at a combined fixed rate of 2.867% for a ten year period effective April 15, 2014, to hedge potential changes in the ten-year LIBOR rate covering the expected borrowing term between now and the expected date that new unsecured borrowings are obtained in 2014.

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) 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.

The following tables represents the effect of the derivative financial instruments on the accompanying consolidated financial statements for the three and nine months ended September 30, 2013 and 2012 (in thousands):

	Fair Value Measurements
	(a) Disclosure of Fair Value of Financial Instruments
	All financial instruments of the Company are reflected in the accompanying Consolidated Balance Sheets at amounts which, in management's estimation, reasonably approximate their fair values, except for the following as of September 30, 2013 and December 31, 2012 (in thousands):
			2013						2012
			Carrying Amount			Fair Value			Carrying Amount		Fair Value
	Financial assets:
	Notes receivable	$	26,128			25,755		$	23,751		23,677
	Financial liabilities:
	Notes payable	$	1,764,437			1,930,004		$	1,771,891		2,000,000
	Unsecured credit facilities	$	100,000			100,476		$	170,000		170,200
	The table above reflects carrying amounts in the accompanying Consolidated Balance Sheets under the indicated captions. The above fair values represent the amounts that would be received from selling those assets or that would be paid to transfer those liabilities in an orderly transaction between market participants as of September 30, 2013 and December 31, 2012. 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. The Company's valuation policies and procedures are determined by its Finance Group, which reports to the Chief Financial Officer, and the results of material fair value measurements are discussed with the Audit Committee of the Board of Directors on a quarterly 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 loan to value ratio on the underlying property securing the note receivable.
	Notes Payable
	The fair value of the Company's 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 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.
	As of September 30, 2013 and December 31, 2012 the following interest rates were used by the Company to estimate the fair value of its financial instruments:
			2013				2012
			Low		High		Low		High
	Notes receivable		5.00%		7.70%		7.00%		8.10%
	Notes payable		2.40%		3.60%		2.40%		3.30%
	Unsecured credit facilities		1.50%		1.50%		1.60%		1.60%
	(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 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. 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.
	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 as of September 30, 2013 and December 31, 2012 (in thousands):

	(1) Excludes impairments for properties sold during the year ended December 31, 2012.
	Long-lived assets held and used are comprised primarily of real estate. During the three months ended September 30, 2013, the Company recognized a $6.0 million impairment on a single operating property as a result of an unoccupied anchor declaring bankruptcy, and the inability of the Company, thus far, to re-lease the anchor space.
	The Company recognized a $54.5 million impairment loss related to two operating properties during the year ended December 31, 2012. The majority of this impairment, $50.0 million, related to one operating property, which the Company determined was more likely than not to be sold before the end of its previously estimated hold period, which led to the impairment during the fourth quarter of 2012. The Company subsequently sold this property in May of 2013. The other operating property exhibited weak operating fundamentals, including low economic occupancy for an extended period of time, which led to a $4.5 million impairment during the second quarter of 2012. The Company subsequently sold this property in June of 2013.
Fair value for the long-lived assets held and used measured using Level 3 inputs 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 property specific information, market transactions, and other financial and industry data. The terminal cap rate and discount rate are significant inputs to this valuation. The following are the key inputs used in determining the fair value of real estate measured using Level 3 inputs as of September 30, 2013 and December 31, 2012:
		2013			2012
					Low			High
Direct cap rates		8	%		8.3	%		8.5	%
Rental growth rates		0	%		(8.3	)%		2.5	%
Discount rates		9	%		10.5	%		10.5	%
Terminal cap rates		8.5	%		8.8	%		8.8	%
Changes in these inputs could result in a significant change in the valuation of the real estate and a change in the impairment loss recognized during the period.

	In August 2012, the Parent Company entered into at the market ("ATM") equity distribution agreements through which it is permitted to offer and sell its common stock from time to time. Net proceeds would fund potential acquisition opportunities, development and redevelopment activities, repay amounts outstanding under the credit facilities and for general corporate purposes. Approximately $121.8 million of common stock was offered and sold through this ATM equity program.
	In August 2013, the Parent Company filed a prospectus supplement with respect to a new ATM equity offering program, which ended the prior program established in August 2012. The August 2013 program has similar terms and conditions as the August 2012 program, and authorizes the Parent Company to sell up to $200.0 million of common stock. As of September 30, 2013, $198.4 million in common stock remained available for issuance under this ATM equity program.
	During the three and nine months ended September 30, 2013, the following shares were issued under the ATM equity programs (in thousands, except price per share data):

	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.
	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 $80.0 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 September 30, 2013 and December 31, 2012, the Company had $19.3 million and $20.8 million letters of credit outstanding, respectively.
