Summary of Significant Accounting Policies:
Summary of Significant Accounting Policies:	2. Summary of Significant Accounting Policies: Basis of Presentation: The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. They do not include all of the information and footnotes required by GAAP for complete financial statements and have not been audited by independent public accountants. 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. The unaudited interim consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial statements for the interim periods have been made. The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying consolidated balance sheet as of December 31, 2012 has been derived from the audited financial statements, but does not include all disclosures required by GAAP.

(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 to interest expense over the remaining term of the related debt in a manner that approximates the effective interest method.

Debt premiums (discounts) consist of the following:

(6): 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 June 30, 2013 and December 31, 2012, the total interest rate was 2.99% and 3.00%, respectively.
(7): The Company is in negotiations with the loan servicer, which will likely result in a transition of the property to the loan servicer or receiver.

The interest on the deposit was not restricted. At June 30, 2013 and December 31, 2012, the total interest rate was 1.20% and 1.22%, respectively.

Most of the mortgage loan agreements contain a prepayment penalty provision for the early extinguishment of the debt.

Most of the Company's mortgage notes payable are secured by the properties on which they are placed and are non-recourse to the Company. As of June 30, 2013 and December 31, 2012, a total of $216,421 and $213,466, respectively, of the mortgage notes payable could become recourse to the Company. The Company had indemnity agreements from consolidated joint venture partners for $28,208 of the guaranteed amount at December 31, 2012.

The Company expects that all loan maturities during the next twelve months will be refinanced, restructured, extended and/or paid-off from the Company's line of credit or with cash on hand.

Total interest expense capitalized was $3,135 and $2,562 during the three months ended June 30, 2013 and 2012, respectively, and $6,642 and $4,915 during the six months ended June 30, 2013 and 2012, respectively.

Related party mortgage notes payable are amounts due to affiliates of NML. See Note 17—Related Party Transactions for interest expense associated with loans from NML.

The fair value of mortgage notes payable at June 30, 2013 and December 31, 2012 was $4,730,390 and $4,567,658, respectively, based on current interest rates for comparable loans. The method for computing fair value (Level 2 measurement) was determined using a present value model and an interest rate that included a credit value adjustment based on the estimated value of the property that serves as collateral for the underlying debt.

Co-Venture Arrangement:	6 Months Ended
Co-Venture Arrangement:	Jun. 30, 2013
Co-Venture Arrangement:
Co-Venture Arrangement:	11. 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 and Chandler Fashion Center. 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 Note 13—Stockholders' Equity. The Company received approximately $174,650 in cash proceeds for the overall transaction, of which $6,496 was attributed to the warrant. 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 $86,677 and $92,215 at June 30, 2013 and December 31, 2012, respectively.

Noncontrolling Interests:	Jun. 30, 2013
Noncontrolling Interests:
Noncontrolling Interests:	12. 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 94% and 93% ownership interest in the Operating Partnership as of June 30, 2013 and December 31, 2012, respectively. The remaining 6% and 7% limited partnership interest as of June 30, 2013 and December 31, 2012, respectively, 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 10 trading days ending on the respective balance sheet date. Accordingly, as of June 30, 2013 and December 31, 2012, the aggregate redemption value of the then-outstanding OP Units not owned by the Company was $579,203 and $586,409, respectively. The Company issued common and 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.

Stockholders' Equity:	6 Months Ended
Stockholders' Equity:	Jun. 30, 2013
Stockholders' Equity:
Stockholders' Equity:	13. Stockholders' Equity: Stock Warrants: 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 11—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 was immediately exercisable upon its issuance and was scheduled to expire on December 1, 2012. The warrant had an exercise price of $46.68 per share, with such price subject to anti-dilutive adjustments. The warrant allowed for either gross or net issue settlement at the option of the warrant holder. In the event that the warrant holder elected a net issue settlement, the Company could have elected to settle the warrant in cash or shares; provided, however, that in the event the Company elected to deliver cash, the holder could have elected to instead have the exercise of the warrant satisfied in shares. In addition, the Company had entered into a registration rights agreement with the warrant holders requiring the Company to provide certain registration rights regarding the resale of shares of common stock underlying the warrant. On December 30, 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 issue 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 issue exercise of the remaining 311,786 shares of the warrant and the Company elected to deliver a cash payment of $3,922 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 three months ended September 30, 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. During the three months ended June 30, 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 $171,174 after commissions and other transaction costs. The proceeds from the sales were used to pay down the Company's line of credit. As of June 30, 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 14—Acquisitions) for a value of $30,000, based on the average closing price of the Company's common stock for ten preceding trading days.

Share and Unit-Based Plans:

6 Months Ended

Jun. 30, 2013

Share and Unit-Based Plans:

Share and Unit-Based Plans:

18. Share and Unit-Based Plans:

On February 15, 2013, the Company granted 332,189 limited partnership units of the Operating Partnership ("LTIP Units") under the Long-Term Incentive Plan to seven executive officers at a weighted average grant date fair value of $49.67 per LTIP Unit. The new grants vest over a service period ending December 31, 2013 based on the percentile ranking of the Company in terms of total return to stockholders (the "Total Return") per share of common stock relative to the Total Return of a group of peer REITs, as measured at the end of the measurement period. 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 on a one-unit for one-share basis.

The fair value of the Company's LTIP Units granted in 2013 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, was assumed to follow the Multivariate Geometric Brownian Motion Process. Multivariate Geometric Brownian Motion Process modeling is commonly used in financial markets, as it allows the modeled quantity (in this case, the stock price) to vary randomly from its current value based on the stock price's expected volatility and current market interest rates. The volatilities of the returns on the stock price of the Company and the peer group REITs were estimated based on a one-year look-back period. The expected growth rate of the stock prices over the derived service period was determined with consideration of the risk free rate as of the grant date.

The following summarizes the compensation cost under the share and unit-based plans:

	For the Three Months Ended June 30,				For the Six Months Ended June 30,

	2013		2012		2013		2012
LTIP Units	$	4,692	$	2,321	$	7,650	$	3,868

Phantom stock units		246		255		487		509

	$	5,731	$	3,165	$	10,868	$	7,282

The Company capitalized share and unit-based compensation costs of $650 and $452 for the three months ended June 30, 2013 and 2012, respectively, and $2,088 and $1,772 for the six months ended June 30, 2013 and 2012, respectively. Unrecognized compensation costs of share and unit-based plans at June 30, 2013 consisted of $9,487 from LTIP Units, $913 from stock awards, $4,324 from stock units, $68 from stock options and $1,188 from phantom stock units.

The following table summarizes the activity of the non-vested LTIP Units, stock awards, phantom stock units and stock units:

	LTIP Units					Stock Awards					Phantom Stock Units					Stock Units

Subsequent Events:	6 Months Ended
Subsequent Events:	Jun. 30, 2013
Subsequent Events:
Subsequent Events:	20. Subsequent Events: On August 1, 2013, the Company's joint venture in Pacific Premier Retail LP sold Redmond Town Center, a 695,000 square foot community center in Redmond, Washington, for $127,000, resulting in a gain on the sale of assets of approximately $39,400. The Company used its share of the proceeds from the sale to pay down its line of credit. On August 5, 2013, the Company's joint venture in Tysons Corner Center received a commitment to refinance the mortgage note payable on the property. The new $850,000 mortgage note payable is expected to bear interest at 4.10% and mature in January 2024. As a result of this transaction, the joint venture expects to receive approximately $550,000 in loan proceeds in excess of the current mortgage note payable on the property. The Company plans to use its share of the excess proceeds of $275,000 to pay down its line of credit. On August 6, 2013, the Company's line of credit was amended and extended. The amended facility provides for an interest rate of LIBOR plus a spread of 1.375% to 2.0%, depending on the Company's overall leverage levels and matures on August 6, 2018. The interest rate, as of the amendment date, was LIBOR plus 1.50%. In addition, the line of credit can be expanded, depending on certain conditions, up to a total amount of $2,000,000 (without giving effect to the outstanding $125,000 unsecured term loan (See Note 10—Bank and Other Notes Payable)). On August 7, 2013, the Company announced a dividend/distribution of $0.58 per share for common stockholders and OP Unit holders of record on August 20, 2013. All dividends/distributions will be paid 100% in cash on September 6, 2013.

Summary of Significant Accounting Policies: (Policies)	Jun. 30, 2013
Summary of Significant Accounting Policies:
Basis of Presentation:	Basis of Presentation: The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles ("GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. They do not include all of the information and footnotes required by GAAP for complete financial statements and have not been audited by independent public accountants. 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. The unaudited interim consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2012. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the consolidated financial statements for the interim periods have been made. The preparation of consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying consolidated balance sheet as of December 31, 2012 has been derived from the audited financial statements, but does not include all disclosures required by GAAP.

Securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) or earnings per unit (EPU) in the future that were not included in the computation of diluted EPS or EPU because to do so would increase EPS or EPU amounts or decrease loss per share or unit amounts for the period presented.
