Summary of Significant Accounting Policies:	'
	Summary of Significant Accounting Policies:
	Basis of Presentation:
	These consolidated financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") in the United States of America. The accompanying consolidated financial statements include the accounts of the Company and the Operating Partnership. Investments in entities in which the Company has a controlling financial interest or entities that meet the definition of a variable interest entity in which the Company has, as a result of ownership, contractual or other financial interests, both the power to direct activities that most significantly impact the economic performance of the variable interest entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity are consolidated; otherwise they are accounted for under the equity method of accounting and are reflected as investments in unconsolidated joint ventures. All intercompany accounts and transactions have been eliminated in the consolidated financial statements.
	Cash and Cash Equivalents and Restricted Cash:
	The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents, for which cost approximates fair value. Restricted cash includes impounds of property taxes and other capital reserves required under loan agreements.
	Revenues:
	Minimum rental revenues are recognized on a straight-line basis over the terms of the related leases. The difference between the amount of rent due in a year and the amount recorded as rental income is referred to as the "straight-line rent adjustment." Minimum rents were increased by $7,498, $5,399 and $4,557 due to the straight-line rent adjustment during the years ended December 31, 2013, 2012 and 2011, respectively. Percentage rents are recognized and accrued when tenants' specified sales targets have been met.
	Estimated recoveries from certain tenants for their pro rata share of real estate taxes, insurance and other shopping center operating expenses are recognized as revenues in the period the applicable expenses are incurred. Other tenants pay a fixed rate and these tenant recoveries are recognized as revenues on a straight-line basis over the term of the related leases.
	The Management Companies provide property management, leasing, corporate, development, redevelopment and acquisition services to affiliated and non-affiliated shopping centers. In consideration for these services, the Management Companies receive monthly management fees generally ranging from 1.5% to 5% of the gross monthly rental revenue of the properties managed.
	Property:
	Maintenance and repair expenses are charged to operations as incurred. Costs for major replacements and betterments, which includes HVAC equipment, roofs, parking lots, etc., are capitalized and depreciated over their estimated useful lives. Gains and losses are recognized upon disposal or retirement of the related assets and are reflected in earnings.
	Property is recorded at cost and is depreciated using a straight-line method over the estimated useful lives of the assets as follows:
	Buildings and improvements	5 - 40 years
	Tenant improvements	5 - 7 years
	Equipment and furnishings	5 - 7 years
	Capitalization of Costs:
	The Company capitalizes costs incurred in redevelopment, development, renovation and improvement of properties. The capitalized costs include pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. These capitalized costs include direct and certain indirect costs clearly associated with the project. Indirect costs include real estate taxes, insurance and certain shared administrative costs. In assessing the amounts of direct and indirect costs to be capitalized, allocations are made to projects based on estimates of the actual amount of time spent on each activity. Indirect costs not clearly associated with specific projects are expensed as period costs. Capitalized indirect costs are allocated to development and redevelopment activities based on the square footage of the portion of the building not held available for immediate occupancy. If costs and activities incurred to ready the vacant space cease, then cost capitalization is also discontinued until such activities are resumed. Once work has been completed on a vacant space, project costs are no longer capitalized. For projects with extended lease-up periods, the Company ends the capitalization when significant activities have ceased, which does not exceed the shorter of a one-year period after the completion of the building shell or when the construction is substantially complete.
	Investment in Unconsolidated Joint Ventures:
	The Company accounts for its investments in joint ventures using the equity method of accounting unless the Company has a controlling financial interest in the joint venture or the joint venture meets the definition of a variable interest entity in which the Company is the primary beneficiary through both its power to direct activities that most significantly impact the economic performance of the variable interest entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity. Although the Company has a greater than 50% interest in Corte Madera Village, LLC, Pacific Premier Retail LP and Queens JV LP, the Company does not have a controlling financial interest in these joint ventures as it shares management control with the partners in these joint ventures and, therefore, accounts for its investments in these joint ventures using the equity method of accounting.
	Acquisitions:
	The Company allocates the estimated fair value of acquisitions to land, building, tenant improvements and identified intangible assets and liabilities, based on their estimated fair values. In addition, any assumed mortgage notes payable are recorded at their estimated fair values. The estimated fair value of the land and buildings is determined utilizing an “as if vacant” methodology. Tenant improvements represent the tangible assets associated with the existing leases valued on a fair value basis at the acquisition date prorated over the remaining lease terms. The tenant improvements are classified as an asset under property and are depreciated over the remaining lease terms. Identifiable intangible assets and liabilities relate to the value of in-place operating leases which come in three forms: (i) leasing commissions and legal costs, which represent the value associated with “cost avoidance” of acquiring in-place leases, such as lease commissions paid under terms generally experienced in the Company's markets; (ii) value of in-place leases, which represents the estimated loss of revenue and of costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased; and (iii) above or below market value of in-place leases, which represents the difference between the contractual rents and market rents at the time of the acquisition, discounted for tenant credit risks. Leasing commissions and legal costs are recorded in deferred charges and other assets and are amortized over the remaining lease terms. The value of in-place leases are recorded in deferred charges and other assets and amortized over the remaining lease terms plus an estimate of renewal of the acquired leases. Above or below market leases are classified in deferred charges and other assets or in other accrued liabilities, depending on whether the contractual terms are above or below market, and the asset or liability is amortized to minimum rents over the remaining terms of the leases. The remaining lease terms of below‑market leases may include certain below‑market fixed-rate renewal periods. In considering whether or not a lessee will execute a below‑market fixed-rate lease renewal option, the Company evaluates economic factors and certain qualitative factors at the time of acquisition such as tenant mix in the center, the Company's relationship with the tenant and the availability of competing tenant space.
	The Company immediately expenses costs associated with business combinations as period costs.
	Marketable Securities:
	The Company accounted for its investments in marketable debt securities as held-to-maturity securities as the Company had the intent and the ability to hold these securities until maturity. Accordingly, investments in marketable securities were carried at their amortized cost. The discount on marketable securities was amortized into interest income on a straight-line basis over the term of the notes, which approximates the effective interest method.
	Deferred Charges:
	Costs relating to obtaining tenant leases are deferred and amortized over the initial term of the lease agreement using the straight-line method. As these deferred leasing costs represent productive assets incurred in connection with the Company's leasing arrangements at the Centers, the related cash flows are classified as investing activities within the accompanying Consolidated Statements of Cash Flows. Costs relating to financing of shopping center properties are deferred and amortized over the life of the related loan using the straight-line method, which approximates the effective interest method.
	The range of the terms of the agreements is as follows:
	Deferred lease costs	1 - 15 years
	Deferred financing costs	1 - 15 years
	Accounting for Impairment:
	The Company assesses whether an indicator of impairment in the value of its properties exists by considering expected future operating income, trends and prospects, as well as the effects of demand, competition and other economic factors. Such factors include projected rental revenue, operating costs and capital expenditures as well as estimated holding periods and capitalization rates. If an impairment indicator exists, the determination of recoverability is made based upon the estimated undiscounted future net cash flows, excluding interest expense. The amount of impairment loss, if any, is determined by comparing the fair value, as determined by a discounted cash flows analysis, with the carrying value of the related assets. The Company generally holds and operates its properties long-term, which decreases the likelihood of their carrying values not being recoverable. Properties classified as held for sale are measured at the lower of the carrying amount or fair value less cost to sell.
	The Company reviews its investments in unconsolidated joint ventures for a series of operating losses and other factors that may indicate that a decrease in the value of its investments has occurred which is other-than-temporary. The investment in each unconsolidated joint venture is evaluated periodically, and as deemed necessary, for recoverability and valuation declines that are other-than-temporary.
	Derivative Instruments and Hedging Activities:
	The Company recognizes all derivatives in the consolidated financial statements and measures the derivatives at fair value. The Company uses interest rate swap and cap agreements (collectively, "interest rate agreements") in the normal course of business to manage or reduce its exposure to adverse fluctuations in interest rates. The Company designs its hedges to be effective in reducing the risk exposure that they are designated to hedge. Any instrument that meets the cash flow hedging criteria is formally designated as a cash flow hedge at the inception of the derivative contract. On an ongoing quarterly basis, the Company adjusts its balance sheet to reflect the current fair value of its derivatives. To the extent they are effective, changes in fair value are recorded in comprehensive income. Ineffective portions, if any, are included in net income (loss).
	Amounts paid (received) as a result of interest rate agreements are recorded as an addition (reduction) to (of) interest expense.
	If any derivative instrument used for risk management does not meet the hedging criteria, it is marked-to-market each period with the change in value included in the consolidated statements of operations.
	Share and Unit-based Compensation Plans:
	The cost of share and unit-based compensation awards is measured at the grant date based on the calculated fair value of the awards and is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the awards. For market-indexed LTIP awards, compensation cost is recognized under the graded attribution method.
	Income Taxes:
	The Company elected to be taxed as a REIT under the Code commencing with its taxable year ended December 31, 1994. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its taxable income to its stockholders. It is management's current intention to adhere to these requirements and maintain the Company's REIT status. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently to its stockholders. If the Company fails to qualify as a REIT in any taxable year, then it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and to federal income and excise taxes on its undistributed taxable income, if any.
	Each partner is taxed individually on its share of partnership income or loss, and accordingly, no provision for federal and state income tax is provided for the Operating Partnership in the consolidated financial statements. The Company's taxable REIT subsidiaries ("TRSs") are subject to corporate level income taxes, which are provided for in the Company's consolidated financial statements.
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The deferred tax assets and liabilities of the TRSs relate primarily to differences in the book and tax bases of property and to operating loss carryforwards for federal and state income tax purposes. A valuation allowance for deferred tax assets is provided if the Company believes it is more likely than not that all or some portion of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent on the Company generating sufficient taxable income in future periods.
	Segment Information:
	The Company currently operates in one business segment, the acquisition, ownership, development, redevelopment, management and leasing of regional and community shopping centers. Additionally, the Company operates in one geographic area, the United States.
	Fair Value of Financial Instruments:
	The fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity's own assumptions about market participant assumptions.
	Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity's own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	The Company calculates the fair value of financial instruments and includes this additional information in the notes to consolidated financial statements when the fair value is different than the carrying value of those financial instruments. When the fair value reasonably approximates the carrying value, no additional disclosure is made.
	The fair values of interest rate agreements are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fell below or rose above the strike rate of the interest rate agreements. The variable interest rates used in the calculation of projected receipts on the interest rate agreements are based on an expectation of future interest rates derived from observable market interest rate curves and 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. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.
	Concentration of Risk:
	The Company maintains its cash accounts in a number of commercial banks. Accounts at these banks are guaranteed by the Federal Deposit Insurance Corporation ("FDIC") up to $250. At various times during the year, the Company had deposits in excess of the FDIC insurance limit.
	No Center or tenant generated more than 10% of total revenues during the years ended December 31, 2013, 2012 or 2011.
	Management Estimates:
	The preparation of financial statements in conformity with GAAP requires 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.

	-1	The Company's ownership interest in this table reflects its legal ownership interest. Legal ownership may, at times, not equal the Company’s economic interest in the listed properties because of various provisions in certain joint venture agreements regarding distributions of cash flow based on capital account balances, allocations of profits and losses and payments of preferred returns. As a result, the Company’s actual economic interest (as distinct from its legal ownership interest) in certain of the properties could fluctuate from time to time and may not wholly align with its legal ownership interests. Substantially all of the Company’s joint venture agreements contain rights of first refusal, buy-sell provisions, exit rights, default dilution remedies and/or other break up provisions or remedies which are customary in real estate joint venture agreements and which may, positively or negatively, affect the ultimate realization of cash flow and/or capital or liquidation proceeds.
	The Company has recently made the following investments and dispositions in unconsolidated joint ventures:
	On February 24, 2011, the Company's joint venture in Kierland Commons Investment LLC (“KCI”) acquired an additional ownership interest in PHXAZ/Kierland Commons, L.L.C. (“Kierland Commons”), a 434,000 square foot regional shopping center in Scottsdale, Arizona, for $105,550. The Company's share of the purchase price consisted of a cash payment of $34,162 and the assumption of a pro rata share of debt of $18,613. As a result of this transaction, KCI increased its ownership interest in Kierland Commons from 49% to 100%. KCI accounted for the acquisition as a business combination achieved in stages and recognized a remeasurement gain of $25,019 based on the acquisition date fair value and its previously held investment in Kierland Commons. As a result of this transaction, the Company's ownership interest in KCI increased from 24.5% to 50%. The Company's pro rata share of the gain recognized by KCI was $12,510 and was included in equity in income from unconsolidated joint ventures.
	On February 28, 2011, the Company in a 50/50 joint venture acquired The Shops at Atlas Park, a 381,000 square foot community center in Queens, New York, for a total purchase price of $53,750. The Company's share of the purchase price was $26,875. The results of The Shops at Atlas Park are included below for the period subsequent to the acquisition.
	On February 28, 2011, the Company acquired the additional 50% ownership interest in Desert Sky Mall, an 891,000 square foot regional shopping center in Phoenix, Arizona, that it did not own for $27,625. The purchase price was funded by a cash payment of $1,875 and the assumption of the third party's pro rata share of the mortgage note payable on the property of $25,750. Concurrent with the purchase of the partnership interest, the Company paid off the $51,500 loan on the property. Prior to the acquisition, the Company had accounted for its investment in Desert Sky Mall under the equity method. Since the date of acquisition, the Company has included Desert Sky Mall in its consolidated financial statements (See Note 15—Acquisitions).
	On April 1, 2011, the Company's joint venture in SDG Macerich Properties, L.P. ("SDG Macerich") conveyed Granite Run Mall, a 1,033,000 square foot regional shopping center in Media, Pennsylvania, to the mortgage note lender by a deed-in-lieu of foreclosure. The mortgage note was non-recourse. The Company's pro rata share of gain on the extinguishment of debt was $7,753 and was included in equity in income from unconsolidated joint ventures.
	On June 3, 2011, the Company entered into a transaction with General Growth Properties, Inc., whereby the Company acquired an additional 33.3% ownership interest in Arrowhead Towne Center, a 1,198,000 square foot regional shopping center in Glendale, Arizona, an additional 33.3% ownership interest in Superstition Springs Center, a 1,082,000 square foot regional shopping center in Mesa, Arizona, and an additional 50% ownership interest in the land under Superstition Springs Center ("Superstition Springs Land") that it did not own in exchange for six anchor locations, including five former Mervyn's stores (See Note 16—Discontinued Operations) and a cash payment of $75,000. As a result of this transaction, the Company owned a 66.7% ownership interest in Arrowhead Towne Center, a 66.7% ownership interest in Superstition Springs Center and a 100% ownership interest in Superstition Springs Land. Although the Company had a 66.7% ownership interest in Arrowhead Towne Center and Superstition Springs Center upon completion of the transaction, the Company did not have a controlling financial interest in these joint ventures due to the substantive participation rights of the outside partner and, therefore, continued to account for its investments in these joint ventures under the equity method of accounting. Accordingly, no remeasurement gain was recorded on the increase in ownership. The Company has consolidated its investment in Superstition Springs Land since the date of acquisition (See Note 15—Acquisitions) and recorded a remeasurement gain of $1,734 that was included in (loss) gain on remeasurement, sale or write down of assets, net as a result of the increase in ownership. This transaction is referred to herein as the "GGP Exchange".
	On December 31, 2011, the Company and its joint venture partner reached agreement for the distribution and conveyance of interests in SDG Macerich that owned 11 regional shopping centers in a 50/50 partnership. Six of the eleven assets were distributed to the Company on December 31, 2011. The Company received 100% ownership of Eastland Mall, a 1,043,000 square foot regional shopping center in Evansville, Indiana, Lake Square Mall, a 559,000 square foot regional shopping center in Leesburg, Florida, SouthPark Mall, a 904,000 square foot regional shopping center in Moline, Illinois, Southridge Center, an 811,000 square foot community center in Des Moines, Iowa, NorthPark Mall, a 1,050,000 square foot regional shopping center in Davenport, Iowa and Valley Mall, a 504,000 square foot regional shopping center in Harrisonburg, Virginia (collectively referred to herein as the "SDG Acquisition Properties"). The ownership interests in the remaining five regional malls were distributed to the outside partner. The remaining net assets of SDG Macerich were distributed during the year ended December 31, 2012. The SDG Acquisition Properties were recorded at fair value at the date of transfer, which resulted in a gain to the Company of $188,264, which was included in equity in income of unconsolidated joint ventures, based on the fair value of the assets acquired and the liabilities assumed in excess of the book value of the Company's interest in SDG Macerich. The distribution and conveyance of the 11 regional shopping centers is referred to herein as the "SDG Transaction". Prior to the SDG Transaction, the Company accounted for its investment in the SDG Acquisition Properties under the equity method of accounting. Since the date of distribution and conveyance, the Company has included the SDG Acquisition Properties in its consolidated financial statements (See Note 15—Acquisitions).
	On March 30, 2012, the Company sold its 50% ownership interest in Chandler Village Center, a 273,000 square foot community center in Chandler, Arizona, for a total sales price of $14,795, resulting in a gain of $8,184 that was included in(loss) gain on remeasurement, sale or write down of assets, net during the year ended December 31, 2012. The sales price was funded by a cash payment of $6,045 and the assumption of the Company's share of the mortgage note payable on the property of $8,750. The Company used the cash proceeds from the sale to pay down its line of credit and for general corporate purposes.
	On March 30, 2012, the Company sold its 50% ownership interest in Chandler Festival, a 500,000 square foot community center in Chandler, Arizona, for a total sales price of $30,975, resulting in a gain of $12,347 that was included in (loss) gain on remeasurement, sale or write down of assets, net during the year ended December 31, 2012. The sales price was funded by a cash payment of $16,183 and the assumption of the Company's share of the mortgage note payable on the property of $14,792. The Company used the cash proceeds from the sale to pay down its line of credit and for general corporate purposes.

Co-Venture Arrangement: [Abstract]	'
Co-venture Arrangement Disclosure	'
	Co-Venture Arrangement:
	On September 30, 2009, the Company formed a joint venture, whereby a third party acquired a 49.9% interest in Freehold Raceway Mall, a 1,674,000 square foot regional shopping center in Freehold, New Jersey, and Chandler Fashion Center, a 1,321,000 square foot regional shopping center in Chandler, Arizona. As part of this transaction, the Company issued a warrant in favor of the third party to purchase 935,358 shares of common stock of the Company at an exercise price of $46.68 per share (See "Stock Warrants" in Note 14—Stockholders' Equity). The Company received approximately $174,650 in cash proceeds for the overall transaction, of which $6,496 was attributed to the warrants. The Company used the proceeds from this transaction to pay down its line of credit and for general corporate purposes.
	As a result of the Company having certain rights under the agreement to repurchase the assets after the seventh year of the venture formation, the transaction did not qualify for sale treatment. The Company, however, is not obligated to repurchase the assets. The transaction has been accounted for as a profit-sharing arrangement, and accordingly the assets, liabilities and operations of the properties remain on the books of the Company and a co-venture obligation was established for the amount of $168,154, representing the net cash proceeds received from the third party less costs allocated to the warrant. The co-venture obligation is increased for the allocation of income to the co-venture partner and decreased for distributions to the co-venture partner. The co-venture obligation was $81,515 and $92,215 at December 31, 2013 and 2012, respectively.

Noncontrolling Interests	'
	Noncontrolling Interests:
	The Company allocates net income of the Operating Partnership based on the weighted average ownership interest during the period. The net income of the Operating Partnership that is not attributable to the Company is reflected in the consolidated statements of operations as noncontrolling interests. The Company adjusts the noncontrolling interests in the Operating Partnership at the end of each period to reflect its ownership interest in the Company. The Company had a 93% ownership interest in the Operating Partnership as of December 31, 2013 and 2012. The remaining 7% limited partnership interest as of December 31, 2013 and 2012 was owned by certain of the Company's executive officers and directors, certain of their affiliates, and other third party investors in the form of OP Units. The OP Units may be redeemed for shares of stock or cash, at the Company's option. The redemption value for each OP Unit as of any balance sheet date is the amount equal to the average of the closing price per share of the Company's common stock, par value $0.01 per share, as reported on the New York Stock Exchange for the ten trading days ending on the respective balance sheet date. Accordingly, as of December 31, 2013 and 2012, the aggregate redemption value of the then-outstanding OP Units not owned by the Company was $587,917 and $586,409, respectively.
	The Company issued common and cumulative preferred units of MACWH, LP in April 2005 in connection with the acquisition of the Wilmorite portfolio. The common and preferred units of MACWH, LP are redeemable at the election of the holder, the Company may redeem them for cash or shares of the Company's stock at the Company's option, and they are classified as permanent equity.
	Included in permanent equity are outside ownership interests in various consolidated joint ventures. The joint ventures do not have rights that require the Company to redeem the ownership interests in either cash or stock.
	The outside ownership interests in the Company's joint venture in Shoppingtown Mall had a purchase option for $11,366. Due to the redemption feature of the ownership interest in Shoppingtown Mall, these noncontrolling interests were included in temporary equity. The Company exercised its right to redeem the outside ownership interests in the partnership in cash and the redemption closed on September 14, 2011. On December 30, 2011, the Company conveyed Shoppingtown Mall to the mortgage note lender by a deed-in-lieu of foreclosure (See Note 16—Discontinued Operations).

	On September 30, 2009, the Company issued a warrant in connection with its formation of a co-venture to own and operate Freehold Raceway Mall and Chandler Fashion Center (See Note 12—Co-Venture Arrangement). The warrant provided for the purchase of 935,358 shares of the Company's common stock. The warrant was valued at $6,496 and recorded as a credit to additional paid-in capital. The warrant had an exercise price of $46.68 per share, with such price subject to anti-dilutive adjustments. In December 2011, the holders requested a net issue exercise of 311,786 shares of the warrant and the Company elected to deliver a cash payment of $1,278 in exchange for the portion of the warrant exercised. On April 10, 2012, the holders requested a net exercise of an additional 311,786 shares of the warrant and the Company elected to deliver a cash payment of $3,448 in exchange for the portion of the warrant exercised. On October 24, 2012, the holders requested a net exercise of the remaining 311,786 shares of the warrant and the Company elected to deliver a cash payment of $3,923 in exchange for the portion of the warrant exercised.
	At-The-Market Stock Offering Program ("ATM Program"):
	On August 17, 2012, the Company entered into an equity distribution agreement ("Distribution Agreement") with a number of sales agents to issue and sell, from time to time, shares of common stock, par value $0.01 per share, having an aggregate offering price of up to $500,000 (the “Shares”). Sales of the Shares, if any, may be made in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an “at the market” offering, which includes sales made directly on the New York Stock Exchange or sales made to or through a market maker other than on an exchange. The Company will pay each sales agent a commission that will not exceed, but may be lower than, 2% of the gross proceeds of the Shares sold through such sales agent under the Distribution Agreement.
	During the year ended December 31, 2012, the Company sold 2,961,903 shares of common stock under the ATM Program in exchange for aggregate gross proceeds of $177,896 and net proceeds of $175,649 after commissions and other transaction costs. The proceeds from the sales were used to pay down the Company's line of credit. During the year ended December 31, 2013, the Company sold 2,456,956 shares of common stock under the ATM Program in exchange for aggregate gross proceeds of $173,011 and net proceeds of $171,102 after commissions and other transaction costs. The proceeds from the sales were used to pay down the Company's line of credit.
	As of December 31, 2013, $149,093 remained available to be sold under the ATM Program. Actual future sales will depend upon a variety of factors including but not limited to market conditions, the trading price of the Company's common stock and the Company's capital needs. The Company has no obligation to sell the remaining shares available for sale under the ATM Program.
	Stock Issued to Acquire Property:
	On November 28, 2012, the Company issued 535,265 restricted shares of common stock in connection with the acquisition of Kings Plaza Shopping Center (See Note 15—Acquisitions) for a value of $30,000, based on the average closing price of the Company's common stock for the ten preceding trading days.

Acquisitions	'
	Acquisitions:
	Desert Sky Mall:
	On February 28, 2011, the Company acquired the remaining 50% ownership interest in Desert Sky Mall that it did not own for $27,625. The acquisition was completed in order to gain 100% ownership and control over this well located asset. The purchase price was funded by a cash payment of $1,875 and the assumption of the third party's pro rata share of the mortgage note payable on the property of $25,750. Concurrent with the purchase of the partnership interest, the Company paid off the $51,500 loan on the property. Prior to the acquisition, the Company had accounted for its investment under the equity method (See Note 4—Investments in Unconsolidated Joint Ventures). As a result of this transaction, the Company obtained 100% ownership of Desert Sky Mall.
	The following is a summary of the allocation of the fair value of Desert Sky Mall:
	Property	$	46,603
	Deferred charges	5,474
	Cash and cash equivalents	6,057
	Tenant receivables	202
	Other assets	4,481
	Total assets acquired	62,817
	Mortgage note payable	51,500
	Accounts payable	33
	Other accrued liabilities	3,017
	Total liabilities assumed	54,550
	Fair value of acquired net assets (at 100% ownership)	$	8,267
	The Company determined that the purchase price represented the fair value of the additional ownership interest in Desert Sky Mall that was acquired. Accordingly, the Company also determined that the fair value of the acquired ownership interest in Desert Sky Mall equaled the fair value of the Company's existing ownership interest.
	Fair value of existing ownership interest (at 50% ownership)	$	4,164
	Carrying value of investment in Desert Sky Mall	(2,296		)
	Gain on remeasurement	$	1,868
	The Company has included the gain in (loss) gain on remeasurement, sale or write down of assets, net for the year ended December 31, 2011 (See Note 6—Property).
	Superstition Springs Land:
	On June 3, 2011, the Company acquired the additional 50% ownership interest in Superstition Springs Land that it did not own in connection with the GGP Exchange (See Note 4—Investments in Unconsolidated Joint Ventures). Prior to the acquisition, the Company had accounted for its investment in Superstition Springs Land under the equity method. As a result of this transaction, the Company obtained 100% ownership of the land.
	The Company recorded the fair value of Superstition Springs Land at $12,914.

	Share and Unit-based Plans:
	The Company has established share and unit-based compensation plans for the purpose of attracting and retaining executive officers, directors and key employees.
	2003 Equity Incentive Plan:
	The 2003 Equity Incentive Plan ("2003 Plan") authorizes the grant of stock awards, stock options, stock appreciation rights, stock units, stock bonuses, performance-based awards, dividend equivalent rights and OP Units or other convertible or exchangeable units. As of December 31, 2013, stock awards, stock units, LTIP Units (as defined below), stock appreciation rights ("SARs") and stock options have been granted under the 2003 Plan. All stock options or other rights to acquire common stock granted under the 2003 Plan have a term of 10 years or less. These awards were generally granted based on the performance of the Company and the employees. None of the awards have performance requirements other than a service condition of continued employment unless otherwise provided. All awards are subject to restrictions determined by the Company's compensation committee. The aggregate number of shares of common stock that may be issued under the 2003 Plan is 13,825,428 shares. As of December 31, 2013, there were 5,701,863 shares available for issuance under the 2003 Plan.
	Stock Awards:
	The value of the stock awards was determined by the market price of the Company's common stock on the date of the grant. The following table summarizes the activity of non-vested stock awards during the years ended December 31, 2013, 2012 and 2011:

	Stock Units:
	The stock units represent the right to receive upon vesting one share of the Company's common stock for one stock unit. The value of the outstanding stock units was determined by the market price of the Company's common stock on the date of the grant. The following table summarizes the activity of non-vested stock units during the years ended December 31, 2013, 2012 and 2011:
		2013					2012					2011

	SARs:
	The executives have up to 10 years from the grant date to exercise the SARs. Upon exercise, the executives will receive unrestricted common shares for the appreciation in value of the SARs from the grant date to the exercise date.
	The Company determined the value of each SAR awarded during the year ended December 31, 2012 to be $9.67 using the Black‑Scholes Option Pricing Model based upon the following assumptions: volatility of 25.85%, dividend yield of 3.69%, risk free rate of 1.20%, current value of $59.57 and an expected term of 8 years. The value of each of the other outstanding SARs was determined at the grant date to be $7.68 based upon the following assumptions: volatility of 22.52%, dividend yield of 5.23%, risk free rate of 3.15%, current value of $61.17 and an expected term of 8 years. The assumptions for volatility and dividend yield were based on the Company's historical experience as a publicly traded company, the current value was based on the closing price on the date of grant and the risk free rate was based upon the interest rate of the 10-year Treasury bond on the date of grant. The following table summarizes the activity of SARs awards during the years ended December 31, 2013, 2012 and 2011:
		2013					2012					2011

	Long-Term Incentive Plan Units:
	Under the Long-Term Incentive Plan ("LTIP"), each award recipient is issued a form of operating partnership units ("LTIP Units") in the Operating Partnership. Upon the occurrence of specified events and subject to the satisfaction of applicable vesting conditions, LTIP Units (after conversion into OP Units) are ultimately redeemable for common stock of the Company, or cash at the Company's option, on a one-unit for one-share basis. LTIP Units receive cash dividends based on the dividend amount paid on the common stock of the Company. The LTIP may include both market-indexed awards and service-based awards.
	The market-indexed LTIP units vest over the service period of the award based on the percentile ranking of the Company in terms of total return to stockholders (the "Total Return") per common stock share relative to the Total Return of a group of peer REITs, as measured at the end of the measurement period.
	On February 28, 2011, the Company granted 190,000 market-indexed LTIP Units to four executive officers at a weighted average grant date fair value of $43.30 per LTIP Unit. The grants vested over a service period ending January 31, 2012. On February 7, 2012, the compensation committee determined that the LTIP Units granted under the LTIP on February 28, 2011 had vested at the 150% level based on the Company's percentile ranking in terms of Total Return per common stock share compared to the Total Return of a group of peer REITs during the period of February 1, 2011 to January 31, 2012. As a result, the compensation committee granted an additional 95,000 LTIP Units, which vested as of January 31, 2012.
	On February 23, 2012, the Company granted 190,000 market-indexed LTIP Units to four executive officers at a weighted average grant date fair value of $37.77 per LTIP Unit. On April 16, 2012, the Company granted 10,000 market-indexed LTIP Units to a new executive officer at a weighted average grant date fair value of $54.97 per LTIP Unit. The market-indexed LTIP Unit grants vested over a service period ending January 31, 2013. On September 1, 2012, the Company granted 20,000 LTIP Units to a new executive officer at a weighted average fair value of $59.57 per LTIP Unit that were fully vested on the grant date. On February 11, 2013, the compensation committee determined that the market-indexed LTIP Units granted under the LTIP in 2012 had vested at the 100% level, based on the Company's percentile ranking in terms of Total Return per common stock share compared to the Total Return of a group of peer REITs during the period of February 1, 2012 to January 31, 2013. As a result, the 200,000 market-indexed LTIP Units vested as of January 31, 2013.
	On February 15, 2013, the Company granted 332,189 market-indexed LTIP Units ("2013 LTIP Units") to seven executive officers at a weighted average grant date fair value of $66.58 per LTIP Unit. The grants vested over a service period ending December 31, 2013. On January 16, 2014, the compensation committee determined that the 2013 LTIP Units had vested at the 96% level, based on the Company's percentile ranking in terms of Total Return per common stock share compared to the Total Return of a group of peer REITs during the January 1, 2013 to December 31, 2013. As a result, 318,900 LTIP Units vested and 13,289 LTIP Units were forfeited as of December 31, 2013.
	The fair value of the market-indexed LTIP Units was estimated on the date of grant using a Monte Carlo Simulation model. The stock price of the Company, along with the stock prices of the group of peer REITs (for market-indexed awards), is assumed to follow the Multivariate Geometric Brownian Motion Process. Multivariate Geometric Brownian Motion is a common assumption when modeling in financial markets, as it allows the modeled quantity (in this case, the stock price) to vary randomly from its current value and take any value greater than zero. The volatilities of the returns on the share price of the Company and the peer group REITs were estimated based on a look-back period. The expected growth rate of the stock prices over the "derived service period" is determined with consideration of the risk free rate as of the grant date.
	The following table summarizes the activity of non-vested LTIP Units during the years ended December 31, 2013, 2012 and 2011:
		2013					2012					2011

	Stock Options:
	The Company measured the value of each option awarded during the year ended December 31, 2012 to be $9.67 using the Black-Scholes Option Pricing Model based upon the following assumptions: volatility of 25.85%, dividend yield of 3.69%, risk free rate of 1.20%, current value of $59.57 and an expected term of 8 years. The assumptions for volatility and dividend yield were based on the Company's historical experience as a publicly traded company, the current value was based on the closing price on the date of grant and the risk free rate was based upon the interest rate of the 10-year Treasury bond on the date of grant.

Directors' Phantom Stock Plan:
The Directors' Phantom Stock Plan offers non-employee members of the board of directors ("Directors") the opportunity to defer their cash compensation and to receive that compensation in common stock rather than in cash after termination of service or a predetermined period. Compensation generally includes the annual retainers payable by the Company to the Directors. Deferred amounts are generally credited as units of phantom stock at the beginning of each three-year deferral period by dividing the present value of the deferred compensation by the average fair market value of the Company's common stock at the date of award. Compensation expense related to the phantom stock awards was determined by the amortization of the value of the stock units on a straight-line basis over the applicable service period. The stock units (including dividend equivalents) vest as the Directors' services (to which the fees relate) are rendered. Vested phantom stock units are ultimately paid out in common stock on a one-unit for one-share basis. To the extent elected by a Director, stock units receive dividend equivalents in the form of additional stock units based on the dividend amount paid on the common stock. The aggregate number of phantom stock units that may be granted under the Directors' Phantom Stock Plan is 500,000. As of December 31, 2013, there were 223,694 units available for grant under the Directors' Phantom Stock Plan.
The following table summarizes the activity of the non-vested phantom stock units for the years ended December 31, 2013, 2012 and 2011:

Employee Stock Purchase Plan ("ESPP"):
The ESPP authorizes eligible employees to purchase the Company's common stock through voluntary payroll deductions made during periodic offering periods.

A maximum of 750,000 shares of common stock is available for purchase under the ESPP. The number of shares available for future purchase under the plan at December 31, 2013 was 565,325.

	Employee Benefit Plans:
	401(k) Plan:
	The Company has a defined contribution retirement plan that covers its eligible employees (the "Plan"). The Plan is a defined contribution retirement plan covering eligible employees of The Macerich Property Management Company LLC and participating affiliates. The Plan is qualified in accordance with section 401(a) of the Code. Effective January 1, 1995, the Plan was amended to constitute a qualified cash or deferred arrangement under section 401(k) of the Code, whereby employees can elect to defer compensation subject to Internal Revenue Service withholding rules. This Plan was further amended effective as of February 1, 1999 to add The Macerich Company Common Stock Fund as a new investment alternative under the Plan. A total of 150,000 shares of common stock were reserved for issuance under the Plan, which was subsequently increased by an additional 500,000 shares in February 2013. On January 1, 2004, the Plan adopted the "Safe Harbor" provision under Sections 401(k)(12) and 401(m)(11) of the Code. In accordance with adopting these provisions, the Company makes matching contributions equal to 100 percent of the first three percent of compensation deferred by a participant and 50 percent of the next two percent of compensation deferred by a participant. During the years ended December 31, 2013, 2012 and 2011, these matching contributions made by the Company were $3,017, $3,094 and $3,077, respectively. Contributions and matching contributions to the Plan by the plan sponsor and/or participating affiliates are recognized as an expense of the Company in the period that they are made.
	Deferred Compensation Plans:
	The Company has established deferred compensation plans under which key executives of the Company may elect to defer receiving a portion of their cash compensation otherwise payable in one calendar year until a later year. The Company may, as determined by the Board of Directors in its sole discretion prior to the beginning of the plan year, credit a participant's account with a matching amount equal to a percentage of the participant's deferral. The Company contributed $843, $648 and $570 to the plans during the years ended December 31, 2013, 2012 and 2011, respectively. Contributions are recognized as compensation in the periods they are made.

Summary of Significant Accounting Policies: (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation:	'
	Basis of Presentation:
	These consolidated financial statements have been prepared in accordance with generally accepted accounting principles ("GAAP") in the United States of America. The accompanying consolidated financial statements include the accounts of the Company and the Operating Partnership. Investments in entities in which the Company has a controlling financial interest or entities that meet the definition of a variable interest entity in which the Company has, as a result of ownership, contractual or other financial interests, both the power to direct activities that most significantly impact the economic performance of the variable interest entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity are consolidated; otherwise they are accounted for under the equity method of accounting and are reflected as investments in unconsolidated joint ventures. All intercompany accounts and transactions have been eliminated in the consolidated financial statements.
Cash and Cash Equivalents and Restricted Cash:	'
	Cash and Cash Equivalents and Restricted Cash:
	The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents, for which cost approximates fair value. Restricted cash includes impounds of property taxes and other capital reserves required under loan agreements.
Revenues:	'
	Percentage rents are recognized and accrued when tenants' specified sales targets have been met.
	Estimated recoveries from certain tenants for their pro rata share of real estate taxes, insurance and other shopping center operating expenses are recognized as revenues in the period the applicable expenses are incurred. Other tenants pay a fixed rate and these tenant recoveries are recognized as revenues on a straight-line basis over the term of the related leases.
	The Management Companies provide property management, leasing, corporate, development, redevelopment and acquisition services to affiliated and non-affiliated shopping centers.
	Revenues:
	Minimum rental revenues are recognized on a straight-line basis over the terms of the related leases. The difference between the amount of rent due in a year and the amount recorded as rental income is referred to as the "straight-line rent adjustment."
Property:	'
	Property:
	Maintenance and repair expenses are charged to operations as incurred. Costs for major replacements and betterments, which includes HVAC equipment, roofs, parking lots, etc., are capitalized and depreciated over their estimated useful lives. Gains and losses are recognized upon disposal or retirement of the related assets and are reflected in earnings.
	Property is recorded at cost and is depreciated using a straight-line method over the estimated useful lives of the assets as follows:
	Buildings and improvements	5 - 40 years
	Tenant improvements	5 - 7 years
	Equipment and furnishings	5 - 7 years
Capitalization of Costs:	'
	Capitalization of Costs:
	The Company capitalizes costs incurred in redevelopment, development, renovation and improvement of properties. The capitalized costs include pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. These capitalized costs include direct and certain indirect costs clearly associated with the project. Indirect costs include real estate taxes, insurance and certain shared administrative costs. In assessing the amounts of direct and indirect costs to be capitalized, allocations are made to projects based on estimates of the actual amount of time spent on each activity. Indirect costs not clearly associated with specific projects are expensed as period costs. Capitalized indirect costs are allocated to development and redevelopment activities based on the square footage of the portion of the building not held available for immediate occupancy. If costs and activities incurred to ready the vacant space cease, then cost capitalization is also discontinued until such activities are resumed. Once work has been completed on a vacant space, project costs are no longer capitalized. For projects with extended lease-up periods, the Company ends the capitalization when significant activities have ceased, which does not exceed the shorter of a one-year period after the completion of the building shell or when the construction is substantially complete.
Investment in Unconsolidated Joint Ventures:	'
	Investment in Unconsolidated Joint Ventures:
	The Company accounts for its investments in joint ventures using the equity method of accounting unless the Company has a controlling financial interest in the joint venture or the joint venture meets the definition of a variable interest entity in which the Company is the primary beneficiary through both its power to direct activities that most significantly impact the economic performance of the variable interest entity and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the variable interest entity. Although the Company has a greater than 50% interest in Corte Madera Village, LLC, Pacific Premier Retail LP and Queens JV LP, the Company does not have a controlling financial interest in these joint ventures as it shares management control with the partners in these joint ventures and, therefore, accounts for its investments in these joint ventures using the equity method of accounting.
Acquisitions:	'
	Acquisitions:
	The Company allocates the estimated fair value of acquisitions to land, building, tenant improvements and identified intangible assets and liabilities, based on their estimated fair values. In addition, any assumed mortgage notes payable are recorded at their estimated fair values. The estimated fair value of the land and buildings is determined utilizing an “as if vacant” methodology. Tenant improvements represent the tangible assets associated with the existing leases valued on a fair value basis at the acquisition date prorated over the remaining lease terms. The tenant improvements are classified as an asset under property and are depreciated over the remaining lease terms. Identifiable intangible assets and liabilities relate to the value of in-place operating leases which come in three forms: (i) leasing commissions and legal costs, which represent the value associated with “cost avoidance” of acquiring in-place leases, such as lease commissions paid under terms generally experienced in the Company's markets; (ii) value of in-place leases, which represents the estimated loss of revenue and of costs incurred for the period required to lease the “assumed vacant” property to the occupancy level when purchased; and (iii) above or below market value of in-place leases, which represents the difference between the contractual rents and market rents at the time of the acquisition, discounted for tenant credit risks. Leasing commissions and legal costs are recorded in deferred charges and other assets and are amortized over the remaining lease terms. The value of in-place leases are recorded in deferred charges and other assets and amortized over the remaining lease terms plus an estimate of renewal of the acquired leases. Above or below market leases are classified in deferred charges and other assets or in other accrued liabilities, depending on whether the contractual terms are above or below market, and the asset or liability is amortized to minimum rents over the remaining terms of the leases. The remaining lease terms of below‑market leases may include certain below‑market fixed-rate renewal periods. In considering whether or not a lessee will execute a below‑market fixed-rate lease renewal option, the Company evaluates economic factors and certain qualitative factors at the time of acquisition such as tenant mix in the center, the Company's relationship with the tenant and the availability of competing tenant space.
	The Company immediately expenses costs associated with business combinations as period costs.
Marketable Securities:	'
	Marketable Securities:
	The Company accounted for its investments in marketable debt securities as held-to-maturity securities as the Company had the intent and the ability to hold these securities until maturity. Accordingly, investments in marketable securities were carried at their amortized cost. The discount on marketable securities was amortized into interest income on a straight-line basis over the term of the notes, which approximates the effective interest method.
Deferred Charges:	'
	Deferred Charges:
	Costs relating to obtaining tenant leases are deferred and amortized over the initial term of the lease agreement using the straight-line method. As these deferred leasing costs represent productive assets incurred in connection with the Company's leasing arrangements at the Centers, the related cash flows are classified as investing activities within the accompanying Consolidated Statements of Cash Flows. Costs relating to financing of shopping center properties are deferred and amortized over the life of the related loan using the straight-line method, which approximates the effective interest method.
	The range of the terms of the agreements is as follows:
	Deferred lease costs	1 - 15 years
	Deferred financing costs	1 - 15 years
Accounting for Impairment:	'
	Accounting for Impairment:
	The Company assesses whether an indicator of impairment in the value of its properties exists by considering expected future operating income, trends and prospects, as well as the effects of demand, competition and other economic factors. Such factors include projected rental revenue, operating costs and capital expenditures as well as estimated holding periods and capitalization rates. If an impairment indicator exists, the determination of recoverability is made based upon the estimated undiscounted future net cash flows, excluding interest expense. The amount of impairment loss, if any, is determined by comparing the fair value, as determined by a discounted cash flows analysis, with the carrying value of the related assets. The Company generally holds and operates its properties long-term, which decreases the likelihood of their carrying values not being recoverable. Properties classified as held for sale are measured at the lower of the carrying amount or fair value less cost to sell.
	The Company reviews its investments in unconsolidated joint ventures for a series of operating losses and other factors that may indicate that a decrease in the value of its investments has occurred which is other-than-temporary. The investment in each unconsolidated joint venture is evaluated periodically, and as deemed necessary, for recoverability and valuation declines that are other-than-temporary.
Derivative Instruments and Hedging Activities:	'
	Derivative Instruments and Hedging Activities:
	The Company recognizes all derivatives in the consolidated financial statements and measures the derivatives at fair value. The Company uses interest rate swap and cap agreements (collectively, "interest rate agreements") in the normal course of business to manage or reduce its exposure to adverse fluctuations in interest rates. The Company designs its hedges to be effective in reducing the risk exposure that they are designated to hedge. Any instrument that meets the cash flow hedging criteria is formally designated as a cash flow hedge at the inception of the derivative contract. On an ongoing quarterly basis, the Company adjusts its balance sheet to reflect the current fair value of its derivatives. To the extent they are effective, changes in fair value are recorded in comprehensive income. Ineffective portions, if any, are included in net income (loss).
	Amounts paid (received) as a result of interest rate agreements are recorded as an addition (reduction) to (of) interest expense.
	If any derivative instrument used for risk management does not meet the hedging criteria, it is marked-to-market each period with the change in value included in the consolidated statements of operations.
Share and Unit-based Compensation Plans:	'
	Share and Unit-based Compensation Plans:
	The cost of share and unit-based compensation awards is measured at the grant date based on the calculated fair value of the awards and is recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the awards. For market-indexed LTIP awards, compensation cost is recognized under the graded attribution method.
Income Taxes:	'
	Income Taxes:
	The Company elected to be taxed as a REIT under the Code commencing with its taxable year ended December 31, 1994. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement that it distribute at least 90% of its taxable income to its stockholders. It is management's current intention to adhere to these requirements and maintain the Company's REIT status. As a REIT, the Company generally will not be subject to corporate level federal income tax on taxable income it distributes currently to its stockholders. If the Company fails to qualify as a REIT in any taxable year, then it will be subject to federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and to federal income and excise taxes on its undistributed taxable income, if any.
	Each partner is taxed individually on its share of partnership income or loss, and accordingly, no provision for federal and state income tax is provided for the Operating Partnership in the consolidated financial statements. The Company's taxable REIT subsidiaries ("TRSs") are subject to corporate level income taxes, which are provided for in the Company's consolidated financial statements.
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The deferred tax assets and liabilities of the TRSs relate primarily to differences in the book and tax bases of property and to operating loss carryforwards for federal and state income tax purposes. A valuation allowance for deferred tax assets is provided if the Company believes it is more likely than not that all or some portion of the deferred tax assets will not be realized. Realization of deferred tax assets is dependent on the Company generating sufficient taxable income in future periods.
Segment Information:	'
	Segment Information:
	The Company currently operates in one business segment, the acquisition, ownership, development, redevelopment, management and leasing of regional and community shopping centers. Additionally, the Company operates in one geographic area, the United States.
Fair Value of Financial Instruments:	'
	Fair Value of Financial Instruments:
	The fair value hierarchy distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity and the reporting entity's own assumptions about market participant assumptions.
	Level 1 inputs utilize quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity's own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	The Company calculates the fair value of financial instruments and includes this additional information in the notes to consolidated financial statements when the fair value is different than the carrying value of those financial instruments. When the fair value reasonably approximates the carrying value, no additional disclosure is made.
	The fair values of interest rate agreements are determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates fell below or rose above the strike rate of the interest rate agreements. The variable interest rates used in the calculation of projected receipts on the interest rate agreements are based on an expectation of future interest rates derived from observable market interest rate curves and 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. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.
Concentration of Risk:	'
	Concentration of Risk:
	The Company maintains its cash accounts in a number of commercial banks. Accounts at these banks are guaranteed by the Federal Deposit Insurance Corporation ("FDIC") up to $250. At various times during the year, the Company had deposits in excess of the FDIC insurance limit.
	No Center or tenant generated more than 10% of total revenues during the years ended December 31, 2013, 2012 or 2011.
Management Estimates:	'
	Management Estimates:
	The preparation of financial statements in conformity with GAAP requires 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.

	-1	The Company's ownership interest in this table reflects its legal ownership interest. Legal ownership may, at times, not equal the Company’s economic interest in the listed properties because of various provisions in certain joint venture agreements regarding distributions of cash flow based on capital account balances, allocations of profits and losses and payments of preferred returns. As a result, the Company’s actual economic interest (as distinct from its legal ownership interest) in certain of the properties could fluctuate from time to time and may not wholly align with its legal ownership interests. Substantially all of the Company’s joint venture agreements contain rights of first refusal, buy-sell provisions, exit rights, default dilution remedies and/or other break up provisions or remedies which are customary in real estate joint venture agreements and which may, positively or negatively, affect the ultimate realization of cash flow and/or capital or liquidation proceeds.

	-1	The mortgage notes payable balances include the unamortized debt premiums (discounts). Debt premiums (discounts) represent the excess (deficiency) of the fair value of debt over (under) the principal value of debt assumed in various acquisitions and are amortized into interest expense over the remaining term of the related debt in a manner that approximates the effective interest method.
	The debt premiums (discounts) as of December 31, 2013 and 2012 consist of the following:

	-2	The interest rate disclosed represents the effective interest rate, including the debt premiums (discounts) and deferred finance costs.
	-3	The monthly debt service represents the payment of principal and interest.
	-4	The maturity date assumes that all extension options are fully exercised and that the Company does not opt to refinance the debt prior to these dates. These extension options are at the Company's discretion, subject to certain conditions, which the Company believes will be met.
	-5	On September 17, 2013, the Company obtained control of the consolidated joint venture as a result of the Camelback Colonnade Restructuring (See Note 15—Acquisitions). The loan on the property bears interest at an effective rate of 2.16% and matures on October 12, 2015.

	-7	On December 11, 2013, in connection with the sale of the property (See Note 16—Discontinued Operations), a third party assumed the existing loan on the property. As a result, the Company has been discharged from this non-recourse loan.

-11	The loan's original maturity date was December 1, 2013. Accordingly, the loan was in maturity default subsequent to that date. As a result, the Company accrued default interest on the loan at a rate of 4% in addition to the effective rate of interest of 5.19%. In February 2014, the Company reached an agreement with the lender to extend the loan to January 1, 2015 and waive the default interest.
-12	On January 24, 2013, in connection with the Company's acquisition of the property (See Note 15—Acquisitions), the Company placed a new loan on the property that allowed for borrowings of up to $325,000, bears interest at an effective interest rate of 3.61% and matures on February 3, 2021.

-18	On April 30, 2013, the existing loan on Vintage Faire Mall was paid off in full, resulting in a loss of $853 on the early extinguishment of debt. Concurrently, the loan on South Towne Center was transferred to Vintage Faire Mall. An additional $15,200 was borrowed on the loan on Vintage Faire Mall that bears interest at an effective rate of 2.91% and matures on November 5, 2015.
-19	On October 24, 2013, the Company purchased the 33.3% interest in Superstition Springs Center that it did not own (See Note 15—Acquisitions).

[1]	The Company's ownership interest in this table reflects its legal ownership interest. Legal ownership may, at times, not equal the Company’s economic interest in the listed properties because of various provisions in certain joint venture agreements regarding distributions of cash flow based on capital account balances, allocations of profits and losses and payments of preferred returns. As a result, the Company’s actual economic interest (as distinct from its legal ownership interest) in certain of the properties could fluctuate from time to time and may not wholly align with its legal ownership interests. Substantially all of the Company’s joint venture agreements contain rights of first refusal, buy-sell provisions, exit rights, default dilution remedies and/or other break up provisions or remedies which are customary in real estate joint venture agreements and which may, positively or negatively, affect the ultimate realization of cash flow and/or capital or liquidation proceeds.

The Company's ownership interest in this table reflects its legal ownership interest. Legal ownership may, at times, not equal the Company’s economic interest in the listed properties because of various provisions in certain joint venture agreements regarding distributions of cash flow based on capital account balances, allocations of profits and losses and payments of preferred returns. As a result, the Company’s actual economic interest (as distinct from its legal ownership interest) in certain of the properties could fluctuate from time to time and may not wholly align with its legal ownership interests. Substantially all of the Company’s joint venture agreements contain rights of first refusal, buy-sell provisions, exit rights, default dilution remedies and/or other break up provisions or remedies which are customary in real estate joint venture agreements and which may, positively or negatively, affect the ultimate realization of cash flow and/or capital or liquidation proceeds.

(1)The mortgage notes payable balances include the unamortized debt premiums (discounts). Debt premiums (discounts) represent the excess (deficiency) of the fair value of debt over (under) the principal value of debt assumed in various acquisitions and are amortized into interest expense over the remaining term of the related debt in a manner that approximates the effective interest method. The debt premiums (discounts) as of December 31, 2013 and 2012 consist of the following:Property Pledged as Collateral 2013 2012Arrowhead Towne Center $14,642 $17,716Camelback Colonnade 2,120 —Deptford Mall (14) (19)Fashion Outlets of Niagara Falls USA 6,342 7,270FlatIron Crossing — 5,232Great Northern Mall — (28)Superstition Springs Center 895 —Valley Mall (219) (307) $23,766 $29,864

[2]

On September 17, 2013, the Company obtained control of the consolidated joint venture as a result of the Camelback Colonnade Restructuring (See Note 15—Acquisitions). The loan on the property bears interest at an effective rate of 2.16% and matures on October 12, 2015.

[3]

A 49.9% interest in the loan has been assumed by a third party in connection with a co-venture arrangement (See Note 12—Co-Venture Arrangement).

[4]

On December 11, 2013, in connection with the sale of the property (See Note 16—Discontinued Operations), a third party assumed the existing loan on the property. As a result, the Company has been discharged from this non-recourse loan.

[5]

The construction loan on the property allows for borrowings up to $140,000, bears interest at LIBOR plus 2.50% and matures on March 5, 2017, including extension options. At December 31, 2013 and 2012, the total interest rate was 2.96% and 3.00%, respectively.

[6]

On September 30, 2013, the Company conveyed the property to the lender by a deed-in-lieu of foreclosure. As a result, the Company has been discharged from this non-recourse loan (See Note 16—Discontinued Operations).

[7]

On June 4, 2013, the existing loan was paid off in full, which resulted in a gain of $2,791 on the early extinguishment of debt. On November 8, 2013, the Company placed a new $268,000 loan on the property that bears interest at an effective rate of 3.90% and matures on January 5, 2021.

[8]

, the loan was in maturity default subsequent to that date. As a result, the Company accrued default interest on the loan at a rate of 4% in addition to the effective rate of interest of 5.19%. In February 2014, the Company reached an agreement with the lender to extend the loan to January 1, 2015 and waive the default interest.

[9]

On January 24, 2013, in connection with the Company's acquisition of the property (See Note 15—Acquisitions), the Company placed a new loan on the property that allowed for borrowings of up to $325,000, bears interest at an effective interest rate of 3.61% and matures on February 3, 2021. Concurrent with the acquisition, the Company borrowed $100,000 on the loan. On January 31, 2013, the Company exercised its option to borrow an additional $225,000 on the loan.

[10]

On January 3, 2013, the Company exercised its option to borrow an additional $146,000 on the loan.

[11]

The loan bears interest at LIBOR plus 2.25% and matures on March 1, 2017. At December 31, 2013 and 2012, the total interest rate was 3.04% and 3.09%, respectively.

[12]

On August 26, 2013, the loan was paid off in full.

[13]

On December 30, 2013, the loan was paid off in full.

[14]

On May 30, 2013, the consolidated joint venture replaced the existing loan on the property with a new $138,000 loan that bears interest at an effective rate of 3.14% and matures on June 1, 2019.

[15]

On April 30, 2013, the existing loan on Vintage Faire Mall was paid off in full, resulting in a loss of $853 on the early extinguishment of debt. Concurrently, the loan on South Towne Center was transferred to Vintage Faire Mall. An additional $15,200 was borrowed on the loan on Vintage Faire Mall that bears interest at an effective rate of 2.91% and matures on November 5, 2015.

[16]

On October 24, 2013, the Company purchased the 33.3% interest in Superstition Springs Center that it did not own (See Note 15—Acquisitions). In connection with the acquisition, the Company assumed the loan on the property with a fair value of $68,448 that bears interest at an effective rate of 2.00% and matures on October 28, 2016.

[17]

On November 8, 2013, the loan was paid off in full, which resulted in a loss of $506 on the early extinguishment of debt.

[18]

The loan bears interest at LIBOR plus 2.25% and matures on November 6, 2014. At December 31, 2013 and 2012, the total interest rate was 2.73% and 2.12%, respectively.

[19]

On August 1, 2013, the loan was paid off in full.

[20]

The interest rate disclosed represents the effective interest rate, including the debt premiums (discounts) and deferred finance costs.

[21]

The monthly debt service represents the payment of principal and interest.

This unaudited pro forma supplemental information does not purport to be indicative of what the Company's operating results would have been had the acquisitions occurred on January 1, 2012, and may not be indicative of future operating results. The Company has excluded remeasurement gains and acquisition costs from these pro forma results as they are considered significant non‑recurring adjustments directly attributable to the acquisitions.
