Accounting Policies [Abstract]
Summary of Significant Accounting Policies	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 in the United States ("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 an independent registered public accounting firm. On January 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which made certain changes to both the variable interest model and the voting model, including changes to (1) the identification of variable interests (fees paid to a decision maker or service provider), (2) the variable interest entity ("VIE") characteristics for a limited partnership or similar entity and (3) the primary beneficiary determination. The Company evaluated the new standard and determined that no change was required to its accounting for variable interest entities. However, under the guidance of the new standard, all of the Company's consolidated joint ventures, including the Operating Partnership, now meet the definition and criteria as VIEs and the Company is the primary beneficiary of each VIE. The Company's sole significant asset is its investment in the Operating Partnership and as a result, substantially all of the Company's assets and liabilities represent the assets and liabilities of the Operating Partnership. In addition, the Operating Partnership has investments in a number of VIEs. The VIEs included the following assets and liabilities: June 30, December 31, Assets: Properties, net $ 358,921 $ 362,129 Other assets 70,399 74,075 Total assets $ 429,320 $ 436,204 Liabilities: Mortgage notes payable $ 135,199 $ 139,767 Other liabilities 79,296 79,984 Total liabilities $ 214,495 $ 219,751 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, 2015 . 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, 2015 has been derived from the audited financial statements but does not include all disclosures required by GAAP. Recent Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, “Revenue From Contracts With Customers,” which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 states that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” While ASU 2014-09 specifically references contracts with customers, it may apply to certain other transactions such as the sale of real estate or equipment. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year. Accordingly, ASU 2014-09 is effective for the Company beginning January 1, 2018, with early adoption permitted beginning January 1, 2017. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. The Company's adoption of ASU 2015-03 on January 1, 2016 resulted in an adjustment of its consolidated balance sheet at December 31, 2015 to reflect the new presentation required by the standard. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which requires adjustments to provisional amounts used in business combinations during the measurement period to be recognized in the reporting period in which the adjustment amounts are determined. It also requires the disclosure of the impact on changes in estimates on earnings, depreciation, amortization and other income effects. The Company's adoption of this standard on January 1, 2016 did not have an impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which requires lessees to record operating and financing leases as assets and liabilities on the balance sheet and lessors to expense costs that are not initial direct leasing costs. ASU 2016-02 is effective for the Company beginning January 1, 2019. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718)," which amends the accounting for share-based payments, including the income tax consequences, classification of awards and classification on the statement of cash flows. ASU 2016-09 is effective for the Company beginning January 1, 2017. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Joint Ventures	Investments in Unconsolidated Joint Ventures: The Company has made the following recent investments and dispositions in its unconsolidated joint ventures: On February 17, 2015 , the Company acquired the remaining 50% ownership interest in Inland Center , an 867,000 square foot regional shopping center in San Bernardino , California , that it did not previously own for $51,250 . The purchase price was funded by a cash payment of $26,250 and the assumption of the third party's share of the mortgage note payable on the property of $25,000 . Concurrent with the purchase of the joint venture interest, the Company paid off the $50,000 mortgage note payable on the property. The cash payment was funded by borrowings under the Company's line of credit. Prior to the acquisition, the Company had accounted for its investment in Inland Center under the equity method of accounting. Since the date of acquisition, the Company has included Inland Center in its consolidated financial statements (See Note 13 — Acquisitions ). On April 30, 2015 , the Company entered into a 50/50 joint venture with Sears to own nine freestanding stores located at Arrowhead Towne Center , Chandler Fashion Center , Danbury Fair Mall , Deptford Mall , Freehold Raceway Mall , Los Cerritos Center , South Plains Mall , Vintage Faire Mall and Washington Square . The Company invested $150,000 for a 50% ownership interest in the joint venture, which was funded by borrowings under the Company's line of credit. On October 30, 2015 , the Company sold a 40% ownership interest in Pacific Premier Retail LLC (the "PPR Portfolio"), which owns Lakewood Center , a 2,075,000 square foot regional shopping center in Lakewood , California ; Los Cerritos Center , a 1,294,000 square foot regional shopping center in Cerritos , California ; South Plains Mall , a 1,127,000 square foot regional shopping center in Lubbock , Texas ; and Washington Square , a 1,442,000 square foot regional shopping center in Portland , Oregon , for a total sales price of $1,258,643 , resulting in a gain on the sale of assets of $311,194 . The sales price was funded by a cash payment of $545,643 and the assumption of a pro rata share of the mortgage notes payable on the properties of $713,000 . The Company used the cash proceeds from the sales to pay down its line of credit and for general corporate purposes, which included funding the ASR and Special Dividend (See Note 12 — Stockholders' Equity ). Upon completion of the sale of the ownership interest, the Company no longer has a controlling interest in the joint venture due to the substantive participation rights of the outside partner. Accordingly, the Company accounts for its investment in the PPR Portfolio under the equity method of accounting. On January 6, 2016 , the Company sold a 40% ownership interest in Arrowhead Towne Center , a 1,197,000 square foot regional shopping center in Glendale , Arizona , for $289,496 , resulting in a gain on the sale of assets of $104,297 . The sales price was funded by a cash payment of $129,496 and the assumption of a pro rata share of the mortgage note payable on the property of $160,000 . The Company used the cash proceeds from the sale to pay down its line of credit and for general corporate purposes, which included funding the Special Dividend (See Note 12 — Stockholders' Equity ). Upon completion of the sale of the ownership interest, the Company no longer has a controlling interest in the joint venture due to the substantive participation rights of the outside partner. Accordingly, the Company accounts for its investment in Arrowhead Towne Center under the equity method of accounting. On January 14, 2016 , the Company formed a joint venture, whereby the Company sold a 49% ownership interest in Deptford Mall , a 1,040,000 square foot regional shopping center in Deptford , New Jersey ; FlatIron Crossing , a 1,432,000 square foot regional shopping center in Broomfield , Colorado ; and Twenty Ninth Street , an 853,000 square foot regional shopping center in Boulder , Colorado (the " MAC Heitman Portfolio "), for $771,478 , resulting in a gain on the sale of assets of $340,745 . The sales price was funded by a cash payment of $478,608 and the assumption of a pro rata share of the mortgage notes payable on the properties of $292,870 . The Company used the cash proceeds from the sale to pay down its line of credit and for general corporate purposes. Upon completion of the sale of the ownership interest, the Company no longer has a controlling interest in the joint venture due to the substantive participation rights of the outside partner. Accordingly, the Company accounts for its investment in the MAC Heitman Portfolio under the equity method of accounting. On March 1, 2016 , the Company, through a 50/50 joint venture, acquired Country Club Plaza , a 1,300,000 square foot regional shopping center in Kansas City , Missouri , for a purchase price of $660,000 .

Co-Venture Arrangement:
Co-Venture Arrangement	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 1,670,000 square foot regional shopping center in Freehold , New Jersey , and Chandler Fashion Center, a 1,319,000 square foot regional shopping center in Chandler , Arizona . 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. 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.

Noncontrolling Interest [Abstract]
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 June 30, 2016 and December 31, 2015 . The remaining 7% limited partnership interest as of June 30, 2016 and December 31, 2015 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, 2016 and December 31, 2015 , the aggregate redemption value of the then-outstanding OP Units not owned by the Company was $887,777 and $870,625 , respectively.

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.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share and Unit-Based Plans	Share and Unit-Based Plans: 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 the 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 January 1, 2016 , the Company granted 58,786 LTIP Units with a grant date fair value of $80.69 per LTIP Unit that will vest in equal annual installments over a service period ending December 31, 2018 . Concurrently, the Company granted 266,899 market-indexed LTIP Units ("2016 LTIP Units") at a grant date fair value of $53.32 per LTIP Unit that vest over a service period ending December 31, 2018 . The fair value of the 2016 LTIP Units was estimated on the date of grant using a Monte Carlo Simulation model that assumed a risk free interest rate of 1.32% and an expected volatility of 20.31% . On March 4, 2016 , the Company granted 154,686 LTIP Units at a fair value of $79.20 per LTIP Unit that were fully vested on the grant date.

Summary of Significant Accoun27

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2016
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States ("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 an independent registered public accounting firm. On January 1, 2016, the Company adopted Accounting Standards Update (“ASU”) 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis,” which made certain changes to both the variable interest model and the voting model, including changes to (1) the identification of variable interests (fees paid to a decision maker or service provider), (2) the variable interest entity ("VIE") characteristics for a limited partnership or similar entity and (3) the primary beneficiary determination. The Company evaluated the new standard and determined that no change was required to its accounting for variable interest entities. However, under the guidance of the new standard, all of the Company's consolidated joint ventures, including the Operating Partnership, now meet the definition and criteria as VIEs and the Company is the primary beneficiary of each VIE. The Company's sole significant asset is its investment in the Operating Partnership and as a result, substantially all of the Company's assets and liabilities represent the assets and liabilities of the Operating Partnership. In addition, the Operating Partnership has investments in a number of VIEs. The VIEs included the following assets and liabilities: June 30, December 31, Assets: Properties, net $ 358,921 $ 362,129 Other assets 70,399 74,075 Total assets $ 429,320 $ 436,204 Liabilities: Mortgage notes payable $ 135,199 $ 139,767 Other liabilities 79,296 79,984 Total liabilities $ 214,495 $ 219,751 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, 2015 . 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, 2015 has been derived from the audited financial statements but does not include all disclosures required by GAAP.
Recent Accounting Pronouncements	Recent Accounting Pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, “Revenue From Contracts With Customers,” which outlines a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. ASU 2014-09 states that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” While ASU 2014-09 specifically references contracts with customers, it may apply to certain other transactions such as the sale of real estate or equipment. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year. Accordingly, ASU 2014-09 is effective for the Company beginning January 1, 2018, with early adoption permitted beginning January 1, 2017. The Company does not expect the adoption of this standard to have a significant impact on its consolidated financial statements. In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected. The Company's adoption of ASU 2015-03 on January 1, 2016 resulted in an adjustment of its consolidated balance sheet at December 31, 2015 to reflect the new presentation required by the standard. In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which requires adjustments to provisional amounts used in business combinations during the measurement period to be recognized in the reporting period in which the adjustment amounts are determined. It also requires the disclosure of the impact on changes in estimates on earnings, depreciation, amortization and other income effects. The Company's adoption of this standard on January 1, 2016 did not have an impact on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)," which requires lessees to record operating and financing leases as assets and liabilities on the balance sheet and lessors to expense costs that are not initial direct leasing costs. ASU 2016-02 is effective for the Company beginning January 1, 2019. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718)," which amends the accounting for share-based payments, including the income tax consequences, classification of awards and classification on the statement of cash flows. ASU 2016-09 is effective for the Company beginning January 1, 2017. The Company is evaluating the impact of the adoption of this standard on its consolidated financial statements.
