Organization Consolidation And Presentation Of Financial Statements [Abstract]
Business And Organization	Note 1. Business and Organization Cedar Realty Trust, Inc. (the "Company") is a real estate investment trust ("REIT") that focuses primarily on ownership and operation of grocery-anchored shopping centers straddling the Washington, D.C. to Boston corridor. At December 31, 2016, the Company owned and managed a portfolio of 61 operating properties (excluding properties “held for sale”). Cedar Realty Trust Partnership, L.P. (the "Operating Partnership") is the entity through which the Company conducts substantially all of its business and owns (either directly or through subsidiaries) substantially all of its assets. At December 31, 2016, the Company owned a 99.6% economic interest in, and was the sole general partner of, the Operating Partnership. The limited partners’ interest in the Operating Partnership (0.4% at December 31, 2016) is represented by Operating Partnership Units (“OP Units”). The carrying amount of such interest is adjusted at the end of each reporting period to an amount equal to the limited partners’ ownership percentage of the Operating Partnership’s net equity. The 351,000 OP Units outstanding at December 31, 2016 are economically equivalent to the Company’s common stock. The holders of OP Units have the right to exchange their OP Units for the same number of shares of the Company’s common stock or, at the Company’s option, for cash. As used herein, the "Company" refers to Cedar Realty Trust, Inc. and its subsidiaries on a consolidated basis, including the Operating Partnership or, where the context so requires, Cedar Realty Trust, Inc. only.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Principles of Consolidation/Basis of Preparation The consolidated financial statements include the accounts and operations of the Company, the Operating Partnership, its subsidiaries, and certain joint venture partnerships in which it participates. The Company consolidates all variable interest entities (“VIEs”) for which it is the primary beneficiary. Generally, a VIE is an entity with one or more of the following characteristics: (1) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (2) as a group, the holders of the equity investment at risk (a) lack the power through voting or similar rights to make decisions about the entity’s activities that significantly impact the entity’s performance, (b) have no obligation to absorb the expected losses of the entity, or (c) have no right to receive the expected residual returns of the entity, or (3) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity’s activities either involve, or are conducted on behalf of, an investor that has disproportionately fewer voting rights. Significant judgments related to these determinations include estimates about the current and future fair values, performance of real estate held by these VIEs, and general market conditions. In February 2015, the Financial Accounting Standards Board (“FASB”) issued guidance which amends the consolidation requirements, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities. Under the analysis, limited partnerships and other similar entities will be considered variable interest entities unless the limited partners hold substantive kick-out rights or participating rights. The guidance was adopted on January 1, 2016. The Company evaluated its existing joint venture property at San Souci Plaza based on the new guidance, determined the entity is now deemed to be a variable interest entity, and will continue to consolidate the entity. At December 31, 2016, this VIE owned real estate with a carrying value of $26.2 million and no mortgage loan payable. The Company has a 60%-owned joint venture originally formed to develop the project known as Crossroads II. This joint venture is consolidated as it is deemed to be a VIE and the Company is the primary beneficiary. The Company (1) guaranteed all related debt, (2) does not require its partners to fund additional capital requirements, (3) has an economic interest greater than its voting proportion and (4) directs the management activities that significantly impact the performance of the joint venture. At December 31, 2016, this VIE owned real estate with a carrying value of $39.2 million and no mortgage loan payable. On January 23, 2015, the Company acquired the New London Mall joint venture partner’s 60% ownership interest, giving the Company a 100% ownership interest in this property, which is located in New London, Connecticut (See Note 3 - “Real Estate”). Prior to the acquisition of the joint venture partner’s ownership interest, the entity was not a VIE, the Company was the sole general partner and exercised substantial operating control over the entity; accordingly, the Company determined that the entity should be consolidated. The accompanying financial statements are prepared on the accrual basis in accordance with accounting principles generally accepted in the United States (“GAAP”), which requires management to make estimates and assumptions that affect the disclosure of contingent assets and liabilities, the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the periods covered by the financial statements. Actual results could differ from these estimates. Real Estate Investments Real estate investments are carried at cost less accumulated depreciation. The provision for depreciation is calculated using the straight-line method based upon the estimated useful lives of the respective assets of between 3 and 40 years, with buildings being depreciated at the upper end of the range. Depreciation expense amounted to $37.1 million, $35.0 million and $35.0 million for 2016, 2015 and 2014, respectively. Expenditures for betterments that substantially extend the useful lives of the assets are capitalized. Expenditures for maintenance, repairs, and betterments that do not substantially prolong the normal useful life of an asset are charged to operations as incurred. Real estate investments include costs of ground-up development and redevelopment activities, and construction in progress. Capitalized costs, including interest and other carrying costs during the construction and/or renovation periods, are included in the cost of the related asset and charged to operations through depreciation over the asset’s estimated useful life. A variety of costs are incurred in the development and leasing of a property, such as 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. After a determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. The Company ceases capitalization on the portions substantially completed and occupied, or held available for occupancy, and capitalizes only those costs associated with the portions under development. The Company considers a construction project to be substantially completed and held available for occupancy upon the completion of tenant improvements, but not later than one year from cessation of major construction activity. The Company allocates the fair value of real estate acquired to land, buildings and improvements. In addition, the fair value of in-place leases is allocated to intangible lease assets and liabilities. The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, which value is then allocated to land, buildings and improvements based on management’s determination of the fair values of these assets. In valuing an acquired property’s intangibles, factors considered by management include an estimate of carrying costs during the expected lease-up periods, such as real estate taxes, insurance, other operating expenses, and estimates of lost rental revenue during the expected lease-up periods based on its evaluation of current market demand. Management also estimates costs to execute similar leases, including leasing commissions, tenant improvements, legal and other related costs. The values of acquired above-market and below-market leases are recorded based on the present values (using discount rates which reflect the risks associated with the leases acquired) of the differences between the contractual amounts to be received and management’s estimate of market lease rates, measured over the terms of the respective leases that management deemed appropriate at the time of the acquisitions. Such valuations include consideration of the non-cancellable terms of the respective leases as well as any applicable renewal periods. The fair values associated with below-market rental renewal options are determined based on the Company’s experience and the relevant facts and circumstances that existed at the time of the acquisitions. The values of above-market leases are amortized to rental income over the terms of the respective non-cancelable lease periods. The portion of the values of below-market leases associated with the original non-cancelable lease terms are amortized to rental income over the terms of the respective non-cancelable lease periods. The portion of the values of the leases associated with below-market renewal options that are likely of exercise are amortized to rental income over the respective renewal periods. The value of other intangible assets (including leasing commissions, tenant improvements, etc.) is amortized to expense over the applicable terms of the respective leases. If a lease were to be terminated prior to its stated expiration or not renewed, all unamortized amounts relating to that lease would be recognized in operations at that time. Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability of real estate investments held for use is based on an estimate of the future cash flows that are expected to result from the real estate investment’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, capital expenditures, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Sales of real estate are recognized only when sufficient down payments have been obtained, possession and other attributes of ownership have been transferred to the buyer and the Company has no significant continuing involvement. The Company believes these criteria were met for all real estate sold during 2016, 2015 and 2014. Properties Held For Sale The Company follows the guidance for reporting discontinued operations, whereby a disposal of an individual property or group of properties is required to be reported in “discontinued operations” only if the disposal represents a strategic shift that has, or will have, a major effect on the Company’s operations and financial results. The results of operations for those properties not meeting such criteria are reported in “continuing operations” in the consolidated statements of operations. The provisions of the guidance were applied prospectively, i.e., for properties classified as “held for sale” subsequent to December 31, 2013. The results of operations for all properties classified as “held for sale” prior to the adoption of the guidance were reported as “discontinued operations” in the consolidated statements of operations. The carrying values of the assets and liabilities of properties determined to be held for sale, principally the net book values of the real estate and the related mortgage loans payable expected to be assumed by the buyers, are reclassified as “held for sale” on the Company’s consolidated balance sheets at the time such determinations are made, on a prospective basis only. In addition, the Company anticipates that sales of all such properties remaining classified as “held for sale” at the balance sheet date will be concluded within one year from such date. The Company conducts a continuing review of the values for all properties “held for sale” based on final sales prices and sales contracts entered into. Impairment charges/reversals, if applicable, are based on a comparison of the carrying values of the properties with either (1) actual sales prices less costs to sell for properties sold, or contract amounts for properties in the process of being sold, (2) estimated sales prices, less costs to sell, based on discounted cash flow analyses, if no contract amounts were as yet being negotiated (see Note 5 — “Fair Value Measurements”), or (3) with respect to land parcels, estimated sales prices, less costs to sell, based on comparable sales completed in the selected market areas. Prior to the Company’s determination to dispose of properties, which are subsequently reclassified to “held for sale”, the Company performed recoverability analyses based on the estimated undiscounted cash flows that were expected to result from the real estate investments’ use and eventual disposal. The projected undiscounted cash flows of each property reflects that the carrying value of each real estate investment would be recovered. However, as a result of the properties’ meeting the “held for sale” criteria, such properties were written down to the lower of their carrying value and estimated fair values less costs to sell. Cash and Cash Equivalents / Restricted Cash Cash and cash equivalents consist of cash in banks and short-term investments with original maturities when purchased of less than ninety days, and include cash at consolidated joint ventures of $0.5 million and $0.2 million at December 31, 2016 and 2015, respectively. The terms of several of the Company’s mortgage loans payable require the Company to deposit certain replacement and other reserves with its lenders. Such “restricted cash” is generally available only for property-level requirements for which the reserves have been established. Fair Value Measurements The accounting guidance for fair value measurement establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: • Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible while also considering counterparty credit risk in the assessment of fair value. Revenue Recognition and Receivables Management has determined that all of the Company’s leases with its various tenants are operating leases. Rental income with scheduled rent increases is recognized using the straight-line method over the respective non-cancelable terms of the leases. The aggregate excess of rental revenue recognized on a straight-line basis over the contractual base rents is included in receivables on the consolidated balance sheet. Leases also generally contain provisions under which the tenants reimburse the Company for a portion of property operating expenses and real estate taxes incurred, generally attributable to their respective allocable portions of gross leasable area. Such income is recognized in the periods earned. In addition, a limited number of operating leases contain contingent rent provisions under which tenants are required to pay, as additional rent, a percentage of their sales in excess of a specified amount. The Company defers recognition of contingent rental income until those specified sales targets are met. Revenues also include items such as lease termination fees, which tend to fluctuate more than rents from year to year. Termination fees are fees that the Company has agreed to accept in consideration for permitting certain tenants to terminate their lease prior to the contractual expiration. The Company recognizes lease termination income when the following conditions are met: (1) the lease termination agreement has been executed, (2) the lease termination fee is determinable, (3) all the Company’s landlord services pursuant to the terminated lease have been rendered, and (4) collectability of the lease termination fee is assured. The Company must make estimates as to the collectability of its accounts receivable related to base rent, straight-line rent, percentage rent, expense reimbursements and other revenues. When management analyzes accounts receivable and evaluates the adequacy of the allowance for doubtful accounts, it considers such things as historical bad debts, tenant creditworthiness, current economic trends, current developments relevant to a tenant’s business specifically and to its business category generally, and changes in tenants’ payment patterns. The allowance for doubtful accounts was $4.7 million and $4.4 million at December 31, 2016 and 2015, respectively. The provision for doubtful accounts (included in operating, maintenance and management expenses) was $1.2 million, $1.4 million and $1.9 million in 2016, 2015 and 2014, respectively. Segment Information The Company’s primary business is the ownership and operation of grocery-anchored shopping centers Income Taxes The Company, organized in 1984, has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). A REIT will generally not be subject to federal income taxation on that portion of its income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of such REIT taxable income to its shareholders and complies with certain other requirements. As of December 31, 2016, the Company was in compliance with all REIT requirements. The Company follows a two-step approach for evaluating uncertain federal, state and local tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that more-likely-than-not will be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The Company has not identified any uncertain tax positions which would require an accrual. Derivative Financial Instruments The Company occasionally utilizes derivative financial instruments, principally interest rate swaps, to manage its exposure to fluctuations in interest rates. The Company has established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. Derivative financial instruments must be effective in reducing the Company’s interest rate risk exposure in order to qualify for hedge accounting. When the terms of an underlying transaction are modified, or when the underlying hedged item ceases to exist, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income for each period until the derivative financial instrument matures or is settled. Any derivative financial instrument used for risk management that does not meet the hedging criteria is marked-to-market with the changes in value included in net income. The Company has not entered into, and does not plan to enter into, derivative financial instruments for trading or speculative purposes. Share-Based Compensation The Company’s 2012 Stock Incentive Plan (the “2012 Plan”) establishes the procedures for the granting of, among other things, restricted stock awards. The maximum number of shares of the Company’s common stock that may be issued pursuant to the 2012 Plan is 4.5 million (see Note 15 – “Share-Based Compensation”), and the maximum number of shares that may be granted to a participant in any calendar year may not exceed 500,000. All grants issued pursuant to the 2012 Plan generally vest (1) at the end of designated time periods for time-based grants, or (2) upon the completion of a designated period of performance for performance-based grants and satisfaction of performance criteria. Time–based grants are valued according to the market price for the Company’s common stock at the date of grant. For performance-based grants, the Company generally engages an independent appraisal company to determine the value of the shares at the date of grant, taking into account the underlying contingency risks associated with the performance criteria. The value of all grants are being expensed on a straight-line basis over their respective vesting periods (irrespective of achievement of the performance-based grants) adjusted, as applicable, for forfeitures. For restricted share grants subject to graded vesting, the amounts expensed are at least equal to the measured expense of each vested tranche. Based on the terms of the 2012 Plan, those grants of restricted shares that are contributed to the Rabbi Trusts are classified as treasury stock on the Company’s consolidated balance sheet. Supplemental Consolidated Statements of Cash Flows Information Years ended December 31, 2016 2015 2014 Supplemental disclosure of cash activities: Cash paid for interest $ 26,296,000 $ 27,521,000 $ 32,275,000 Supplemental disclosure of non-cash activities: Capitalization of interest and financing costs 743,000 409,000 757,000 Conversions of OP Units into common stock — 282,000 371,000 Mortgage loan payable assumed upon acquisition (8,501,000 ) (20,462,000 ) (53,439,000 ) Mortgage loan assumed by buyer — — 15,557,000 Deed-in-lieu of foreclosure of properties: Real estate transferred — — (6,238,000 ) Mortgage loans payable and related obligations settled — — 7,661,000 Recently-Issued Accounting Pronouncements In May 2014, the FASB issued guidance which amends the accounting for revenue recognition. Under the amended guidance, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to and receive in exchange for those goods or services. Leases are specifically excluded from this guidance and will be governed by the applicable lease codification; however, this update may have implications with respect to certain variable payment terms included in lease agreements. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption not permitted. The Company is currently in the process of evaluating the guidance; however, based on its initial assessment, the Company does not believe it will have a material impact on its consolidated financial statements. In August 2014, the FASB issued guidance which requires management to evaluate whether there are conditions and events that raise substantial doubt about an entity’s ability to continue as a going concern, and to provide disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. The guidance was adopted on January 1, 2016 and did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued guidance which amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of their classification. Leases with a term of twelve months or less will be accounted for pursuant to existing guidance for operating leases. The guidance is expected to result in the recognition of a right-to-use asset and related liability to account for the Company’s future obligations under its ground lease and executive office lease agreements for which the Company is the lessee. As of December 31, 2016, the remaining contractual payments under the Company’s ground lease and executive office lease agreements aggregated $17.1 million with a remaining weighted average term of 46.1 years. Additionally, the guidance will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under this guidance, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. Lessors will continue to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. In March 2016, the FASB issued guidance which amends the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued guidance which enhances the methodology of measuring expected credit losses to include the use of forward-looking information to better calculate credit loss estimates. The guidance will apply to most financial assets measured at amortized cost and certain other instruments, including accounts receivable, straight-line rent receivables, loans, held-to-maturity debt securities, net investments in leases, and off-balance-sheet credit exposures. The guidance will require that the Company estimate the lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. The Company will also be required to disclose information about how it developed the allowances, including changes in the factors that influenced the Company’s estimate of expected credit losses and the reasons for those changes. In August 2016, the FASB issued guidance that clarifies how an entity should classify certain cash receipts and cash payments on its statement of cash flows. The guidance established that an entity will classify cash payments for debt prepayment or extinguishment costs as financing cash flows. In addition, the guidance provides entities with an alternative to consider regarding the nature of the source of distributions that an investor receives from an equity method investment when classifying distributions received in its cash flow statement (the nature of the distribution approach). Alternatively, entities can elect to classify the distributions received from equity method investees based on the cumulative earnings approach. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued guidance that will require entities to show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows. When cash, cash equivalents and restricted cash are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued guidance which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in the guidance on revenue from contracts with customers. The Company believes that most of its typical acquisitions of real estate will not meet the new definition of a business, and accordingly, will result in the capitalization of associated acquisition pursuit costs. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has elected to early adopt this guidance effective January 1, 2017.

See Note 9 - “Mortgage Loans Payable and Credit Facilities”. 2017 Acquisition On February 22, 2017, the Company acquired Christina Crossing, located in Wilmington, Delaware. The purchase price for the property, which was unencumbered, was $29.3 million. 2016 Acquisitions On February 25, 2016, the Company acquired Shoppes at Arts District, located in Hyattsville, Maryland. The purchase price for the property was $20.5 million, of which $8.5 million was funded from the assumption of a mortgage loan payable bearing interest at the rate of 5.2% per annum and maturing in April 2022. On May 4, 2016, the Company acquired Glenwood Village, located in Bloomfield, New Jersey. The purchase price for the property, which was unencumbered, was $19.5 million. 2015 Acquisitions On January 23, 2015, the Company acquired the New London Mall joint venture partner’s 60% ownership interest, giving the Company a 100% ownership interest in this property, which is located in New London, Connecticut. The purchase price for the interest was $27.3 million, consisting of $10.9 million in cash, and $16.4 million representing the 60% share of the in-place mortgage financing. As the property was previously controlled and consolidated by the Company, the acquisition of the 60% noncontrolling ownership interest was recorded as a capital transaction.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 5. Fair Value Measurements The carrying amounts of cash and cash equivalents, restricted cash, rents and other receivables, certain other assets, accounts payable and accrued liabilities, and variable-rate debt approximate their fair value due to their terms and/or short-term nature. The fair value of the Company’s investments and liabilities related to share-based compensation were determined to be Level 1 within the valuation hierarchy, and were based on independent values provided by financial institutions. The fair value of the Company’s fixed rate mortgage loans were estimated using available market information and discounted cash flow analyses based on borrowing rates the Company believes it could obtain with similar terms and maturities. As of December 31, 2016 and December 31, 2015, the aggregate fair values of the Company’s fixed rate mortgage loans payable, which were determined to be Level 3 within the valuation hierarchy, were $143.2 million and $308.1 million, respectively; the carrying values of such loans were $138.2 million and $298.1 million, respectively. As of December 31, 2016 and December 31, 2015, respectively, the aggregate fair values of the Company’s unsecured revolving credit facility and term loans approximated the carrying values. The valuation of the liabilities for the Company’s interest rate swaps, which are measured on a recurring basis, were determined to be Level 2 within the valuation hierarchy, and were based on independent values provided by financial institutions. Such valuations were determined using widely accepted valuation techniques, including discounted cash flow analyses, on the expected cash flows of each derivative. The analyses reflect the contractual terms of the swaps, including the period to maturity, and user-observable market-based inputs, including interest rate curves (“significant other observable inputs”). The fair value calculation also includes an amount for risk of non-performance using “significant unobservable inputs” such as estimates of current credit spreads to evaluate the likelihood of default. The Company has concluded that, as of December 31, 2016, the fair value associated with the “significant unobservable inputs” relating to the Company’s risk of non-performance was insignificant to the overall fair value of the interest rate swap agreements and, as a result, that the relevant inputs for purposes of calculating the fair value of the interest rate swap agreements, in their entirety, were based upon “significant other observable inputs”. Nonfinancial assets and liabilities measured at fair value in the consolidated financial statements consist of real estate held for sale, which, if applicable, are measured on a nonrecurring basis, have been determined to be (1) Level 2 within the valuation hierarchy, where applicable, based on the respective contracts of sale, adjusted for closing costs and expenses, or (2) Level 3 within the valuation hierarchy, where applicable, based on estimated sales prices, adjusted for closing costs and expenses, determined by discounted cash flow analyses, direct capitalization analyses or a sales comparison approach if no contracts had been concluded. The discounted cash flow and direct capitalization analyses include all estimated cash inflows and outflows over a specific holding period and, where applicable, any estimated debt premiums. These cash flows were composed of unobservable inputs which included forecasted rental revenues and expenses based upon existing in-place leases, market conditions and expectations for growth. Capitalization rates and discount rates utilized in these analyses were based upon observable rates that the Company believed to be within a reasonable range of current market rates for the respective properties. The sales comparison approach is utilized for certain land values and includes comparable sales that were completed in the selected market areas. The comparable sales utilized in these analyses were based upon observable per acre rates that the Company believes to be within a reasonable range of current market rates for the respective properties. Valuations were prepared using internally-developed valuation models. These valuations are reviewed and approved, during each reporting period, by a diverse group of management, as deemed necessary, including personnel from the acquisition, accounting, finance, operations, development and leasing departments, and the valuations are updated as appropriate. In addition, the Company may engage third-party valuation experts to assist with the preparation of certain of its valuations. The following tables show the hierarchy for those assets measured at fair value on a recurring basis as of December 31, 2016 and December 31, 2015, respectively: December 31, 2016 Description Level 1 Level 2 Level 3 Total Investments related to deferred compensation liabilities (a) $ 447,000 $ — $ — $ 447,000 Deferred compensation liabilities (b) $ 435,000 $ — $ — $ 435,000 Interest rate swaps asset (a) $ — $ 3,074,000 $ — $ 3,074,000 Interest rate swaps liability (b) $ — $ 2,321,000 $ — $ 2,321,000 December 31, 2015 Description Level 1 Level 2 Level 3 Total Investments related to deferred compensation liabilities (a) $ 539,000 $ — $ — $ 539,000 Deferred compensation liabilities (b) $ 529,000 $ — $ — $ 529,000 Interest rate swaps liability (b) $ — $ 3,945,000 $ — $ 3,945,000 (a) Included in other assets and deferred charges, net in the accompanying consolidated balance sheets.

Risks And Uncertainties [Abstract]
Concentration Of Credit Risk	Note 6. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents in excess of insured amounts and tenant receivables. The Company places its cash and cash equivalents with high quality financial institutions. Management performs ongoing credit evaluations of its tenants and requires certain tenants to provide security deposits and/or suitable guarantees. Excluding properties held for sale, Giant Food Stores, LLC, Stop & Shop, Inc. and Food Lion, LLC, each of which is owned by Ahold N.V., a Netherlands corporation, accounted for an aggregate of approximately 12%, 12% and 14% of the Company’s total revenues during 2016, 2015 and 2014, respectively. The Company’s properties are located largely in the region straddling the Washington, D.C. to Boston corridor, which exposes it to greater economic risks than if the properties it owned were located in a greater number of geographic regions (in particular, 26 of the Company’s properties are located in Pennsylvania).

Debt Disclosure [Abstract]
Mortgage Loans Payable And Unsecured Credit Facilities	Note 9. Mortgage Loans Payable and Unsecured Credit Facilities In April 2015, the FASB issued guidance which amends the balance sheet presentation for debt issuance costs. Under the amended guidance, the Company presents the balance of unamortized debt issuance costs for mortgage loans payable and term loans as a direct deduction from the carrying amount of that debt liability. The guidance was adopted on January 1, 2016 and has been applied on a retrospective basis, and, as a result of the adoption, unamortized debt issuance costs for mortgage loans payable and term loans, aggregating $0.9 million and $2.3 million, respectively, have been reclassified from other assets and deferred charges, net, on the consolidated balance sheet. Debt is composed of the following at December 31, 2016 and 2015: December 31, 2016 December 31, 2015 Contractual interest rates Contractual interest rates Balance Weighted - Balance Weighted - Description outstanding average Range outstanding average Range Fixed-rate mortgages $ 138,288,000 4.6% 3.9% - 7.5% $ 298,779,000 5.4% 3.9% - 7.5% Unsecured credit facilities: Variable-rate: Revolving credit facility 72,000,000 2.1% 78,000,000 1.7% Term loan 50,000,000 2.1% 50,000,000 1.7% Fixed-rate (a): Term loan 75,000,000 2.9% 75,000,000 2.9% Term loan 50,000,000 2.8% 50,000,000 2.8% Term loan 75,000,000 4.0% 75,000,000 4.0% Term loan 50,000,000 3.3% 50,000,000 3.3% Term loan 100,000,000 3.2% - - 610,288,000 3.3% 676,779,000 3.3% Unamortized premium 667,000 243,000 Unamortized debt issuance costs (3,210,000 ) (3,202,000 ) $ 607,745,000 $ 673,820,000 (a) The interest rates on these term loans consist of LIBOR plus a credit spread based on the Company’s leverage ratio, for which the Company has interest rate swap agreements which convert the LIBOR rates to fixed rates. Accordingly, these term loans are presented as fixed-rate debt. Mortgage Loans Payable During 2016 and 2015, the Company repaid the following mortgage loans payable: Principal payoff Property Repayment date amount Gold Star Plaza March 10, 2016 $ 953,000 West Bridgewater June 6, 2016 $ 10,037,000 Hamburg Square July 1, 2016 $ 4,569,000 Meadows Marketplace August 1, 2016 $ 9,089,000 Carman's Plaza August 1, 2016 $ 33,500,000 San Souci Plaza September 1, 2016 $ 27,200,000 Camp Hill September 30, 2016 $ 60,742,000 Swede Square December 29, 2016 $ 9,652,000 Golden Triangle December 30, 2016 $ 18,496,000 Principal payoff Property Repayment date amount New London Mall February 1, 2015 $ 27,365,000 Oak Ridge Shopping Center March 11, 2015 $ 3,155,000 Pine Grove Plaza June 1, 2015 $ 5,139,000 Quartermaster Plaza July 1, 2015 $ 41,327,000 Groton Shopping Center July 1, 2015 $ 10,953,000 Jordan Lane August 2, 2015 $ 11,682,000 Southington Center August 2, 2015 $ 5,129,000 Oakland Mills September 1, 2015 $ 4,385,000 During 2016 and 2015, in connection with these repayments, the Company incurred charges relating to early extinguishment of mortgage loans payable (prepayment penalties and accelerated amortization of deferred financing costs) of $2.6 million and $0.1 million, respectively, included in continuing operations.

Unsecured Revolving Credit Facility and Term Loans The Company has a $310 million unsecured credit facility which, as amended on February 5, 2015, consists of (1) a $260 million revolving credit facility, expiring on February 5, 2019, and (2) a $50 million term loan, expiring on February 5, 2020. The revolving credit facility may be extended, at the Company’s option, for an additional one-year period, subject to customary conditions. Under an accordion feature, the facility can be increased to $750 million, subject to customary conditions and lending commitments. Interest on borrowings under the revolving credit facility component can range from LIBOR plus 135 basis points (“bps”) to 195 bps (135 bps at December 31, 2016) and interest on borrowings under the term loan component can range from LIBOR plus 130 to 190 bps (130 bps at December 31, 2016), each based on the Company’s leverage ratio. As of December 31, 2016, the Company had $168.0 million available for additional borrowings under the revolving credit facility. The Company has $150 million of unsecured term loans comprised of a five-year $75 million term loan, maturing on February 11, 2019, and a seven-year $75 million term loan, maturing on February 11, 2021. Interest on borrowings under the five-year $75 million term loan can range from LIBOR plus 130 bps to 190 bps (130 bps at December 31, 2016) and interest on borrowings under the seven-year $75 million term loan can range from LIBOR plus 170 bps to 230 bps (170 bps at December 31, 2016), each based on the Company’s leverage ratio. Additionally, the Company has entered into forward interest rate swap agreements which convert the LIBOR rates to fixed rates for these term loans through their maturities. Based on the Company’s leverage ratio as of December 31, 2016, the effective fixed interest rates are 2.9% for the five-year $75 million term loan and 4.0% for the seven-year $75 million term loan, respectively. On February 5, 2015, the Company closed $100 million of new unsecured term loans comprised of a five-year $50 million term loan maturing February 5, 2020 (all of which was borrowed at closing), and a seven-year $50 million term loan maturing February 5, 2022 (all of which was borrowed on June 26, 2015). Interest on borrowings under the five-year $50 million term loan can range from LIBOR plus 130 to 190 bps (130 bps at December 31, 2016) and interest on borrowings under the seven-year $50 million term loan can range from LIBOR plus 155 bps to 215 bps (155 bps at December 31, 2016), each based on the Company’s leverage ratio. Additionally, the Company entered into forward interest rate swap agreements which convert the LIBOR rates to fixed rates for these term loans beginning on July 1, 2015 through their maturities. Based on the Company’s leverage ratio as of December 31, 2016, the effective fixed interest rates are 2.8% for the five-year $50 million term loan and 3.3% for the seven-year $50 million term loan. On April 26, 2016, the Company closed a new $100 million unsecured term loan maturing on April 26, 2023 (all of which was borrowed on September 30, 2016). Proceeds were used primarily to repay mortgages maturing through January 2017. Interest on borrowings under the term loan can range from LIBOR plus 165 to 225 bps (165 bps on December 31, 2016), based on the Company’s leverage ratio. Additionally, the Company entered into a forward interest rate swap agreement which converts the LIBOR rate to a fixed rate for the term loan beginning November 1, 2016 through its maturity. Based on the Company’s leverage ratio as of December 31, 2016, the effective fixed interest rate is 3.2%. The Company’s unsecured credit facility and term loans contain financial covenants including, but not limited to, maximum debt leverage, maximum secured debt, minimum fixed charge coverage, and minimum net worth. In addition, the facility contains restrictions including, but not limited to, limits on indebtedness, certain investments and distributions. Although the credit facility is unsecured, borrowing availability is based on unencumbered property adjusted net operating income, as defined in the agreements. The Company’s failure to comply with the covenants or the occurrence of an event of default under the facilities could result in the acceleration of the related debt. As of December 31, 2016 the Company is in compliance with all financial covenants. Interest on borrowings under the unsecured credit facility and terms loans are based on the Company’s leverage ratio. Scheduled Scheduled principal payments on mortgage loans payable, unsecured term loans, and the unsecured credit facility at December 31, 2016, due on various dates from 2017 to 2029, are as follows: Secured Debt Unsecured Debt Unamortized Scheduled Balloon Revolving Term Unamortized Debt Year Amortization Payments Credit Facility Loans Total Premium Issuance Costs Total 2017 $ 3,221,000 $ - $ - $ - $ 3,221,000 $ 119,000 $ (759,000 ) $ 2,581,000 2018 3,377,000 - - - 3,377,000 126,000 (759,000 ) 2,744,000 2019 3,542,000 - 72,000,000 (a) 75,000,000 150,542,000 126,000 (607,000 ) 150,061,000 2020 3,707,000 - - 100,000,000 103,707,000 126,000 (391,000 ) 103,442,000 2021 3,253,000 22,367,000 - 75,000,000 100,620,000 126,000 (259,000 ) 100,487,000 Thereafter 11,561,000 87,260,000 - 150,000,000 248,821,000 44,000 (435,000 ) 248,430,000 $ 28,661,000 $ 109,627,000 $ 72,000,000 $ 400,000,000 $ 610,288,000 $ 667,000 $ (3,210,000 ) $ 607,745,000 (a) The revolving credit facility is subject to a one-year extension at the Company's option. Derivative Financial Instruments At December 31, 2016, the Company had $3.1 million included in other assets and deferred charges, net, in addition to $2.3 million included in accounts payable and accrued liabilities on the consolidated balance sheet relating to the fair value of the interest rate swaps applicable to the unsecured term loans discussed above. Charges and/or credits relating to the changes in the fair value of the interest rate swaps are made to accumulated other comprehensive income (loss), noncontrolling interests (minority interests in consolidated joint ventures and limited partners’ interest), or operations (included in interest expense), as applicable. Over time, the unrealized gains and losses recorded in accumulated other comprehensive loss will be reclassified into earnings as an increase or reduction to interest expense in the same periods in which the hedged interest payments affect earnings. The Company estimates that approximately $3.0 million of accumulated other comprehensive loss will be reclassified as a charge to earnings within the next twelve months.

Commitments And Contingencies Disclosure [Abstract]
Commitments And Contingencies	Note 11. Commitments and Contingencies The Company is a party to certain legal actions arising in the normal course of business. Management does not expect there to be adverse consequences from these actions that would be material to the Company’s consolidated financial statements. Under various federal, state, and local laws, ordinances, and regulations, an owner or operator of real estate may be required to investigate and clean up hazardous or toxic substances, or petroleum product releases, at its properties. The owner may be liable to governmental entities or to third parties for property damage, and for investigation and cleanup costs incurred by such parties in connection with any contamination. Generally, the Company’s tenants must comply with environmental laws and meet any remediation requirements. In addition, leases typically impose obligations on tenants to indemnify the Company from any compliance costs the Company may incur as a result of environmental conditions on the property caused by the tenant. However, if a lease does not require compliance, or if a tenant fails to or cannot comply, the Company could be forced to pay these costs. Management is unaware of any environmental matters that would have a material impact on the Company’s consolidated financial statements. The Company’s executive offices are located at 44 South Bayles Avenue, Port Washington, New York. The terms of the lease, which will expire in February 2020, provide for future minimum rents as follows: 2017 - $489,000, 2018 - $503,000, 2019 - $517,000 and 2020 - $86,000. In addition, several of the Company’s properties and portions of several others are owned subject to operating leases which provide for annual payments subject, in certain cases, to cost-of-living, as follows: 2017 - $0.5 million, 2018 - $0.4 million, 2019 - $0.4 million, 2020 - $0.4 million, 2021 - $0.4 million, and thereafter - $13.5 million. Rent expense was $1.5 million, $1.5 million and $1.3 million for 2016, 2015 and 2014, respectively.

Stockholders Equity Note [Abstract]
Shareholders' Equity	Note 12. Shareholders’ Equity Preferred Stock The Company’s 7.25% Series B Cumulative Redeemable Preferred Stock (“Series B Preferred Stock”) has a liquidation preference of $25.00 per share, has no stated maturity, is not convertible into any other security of the Company, and is redeemable at the Company’s option beginning May 22, 2017 at a price of $25.00 per share plus accrued and unpaid distributions. In addition, the Company had an at-the-market equity program, which expired on May 29, 2015, under which the Company could offer and sell, from time-to-time, shares of its Series B Preferred Stock. There were no transactions during 2015 under this program. Common Stock On August 1, 2016, the Company entered into a forward sales agreement to issue 5,750,000 common shares for estimated net proceeds of $44.2 million, before adjustments for dividends paid and other administrative costs incurred prior to settlement. To date, there have been no physical settlements regarding this offering. The Company expects to physically settle the agreement in full prior to its expiration on August 1, 2017. The Company does have the option to net settle this agreement in shares or cash prior to its expiration, but does not expect to utilize this option. On January 12, 2015, the Company concluded a public offering of 5,750,000 shares of its common stock (including 750,000 shares relating to the exercise of an over-allotment option by the underwriters), and realized net proceeds, after offering expenses, of approximately $41.9 million. The Company had an at-the-market offering program, which expired on May 29, 2015, under which it could offer and sell, from time-to-time, shares of its common stock. Prior to the expiration of this program, no shares were sold in 2015. The Company has a Dividend Reinvestment and Direct Stock Purchase Plan (“DRIP”) which offers a convenient method for shareholders to invest cash dividends and/or make optional cash payments to purchase shares of the Company’s common stock. Such purchases are at 100% of market value. There were no significant transactions under the DRIP during 2016 and 2015. At December 31, 2016, there remained 2,841,000 shares authorized under the DRIP. OP Units Certain noncontrolling interests of the Company had been classified in the mezzanine section of the balance sheet (the “mezzanine OP Units”) as such OP Units had not met the requirements for equity classification (the holders of such OP Units had, under the federal securities laws, demand registration rights of the Company’s common stock upon conversion of such OP Units). Such registration rights expired on April 25, 2015 and, accordingly, such OP Units now meet the requirements for equity classification. There were no significant OP Unit redemptions during 2016 and 2015. During 2015, holders of 40,000 OP Units converted their holdings to shares of the Company’s common stock. Dividends The following table provides a summary of dividends declared and paid per share: Years ended December 31, 2016 2015 2014 Common stock $ 0.200 $ 0.200 $ 0.200 7.250% Series B Preferred Stock $ 1.812 $ 1.812 $ 1.812 At December 31, 2016 and 2015, there were $1.6 million and $1.6 million, respectively, of accrued preferred stock dividends.

At December 31, 2016, 1.2 million shares remained available for grants pursuant to the 2012 Plan and, at that date, there remained an aggregate of $6.1 million applicable to all grants and awards to be expensed over a weighted average period of 2.4 years. During 2016, there were 491,000 time-based restricted shares granted with a weighted average grant date fair value of $6.87 per share. During 2015, there were 180,000 time-based restricted shares issued, with a weighted average grant date fair value of $7.43 per share. During 2014, there were 133,000 time-based restricted shares granted, with a weighted average grant date fair value of $6.32 per share.

The Company’s President and Chief Executive Officer has received restricted share grants totaling 2.5 million shares as provided in his employment agreement, one-half of which is time-based, vesting upon the seventh anniversary of the date of grant (vesting on June 15, 2018), and the other half performance-based, to be earned if the total annual return on an investment in the Company’s common stock is at least an average of 6.5% per year for the seven years ending June 15, 2018. An independent appraisal determined the value of the performance-based award to be $4.39 per share compared to a market price at the date of grant of $4.98 per share. Consistent with such awards to other recipients, dividends have been paid on all the shares.

Earnings Per Share

Earnings Per Share	12 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Note 16. Earnings Per Share Basic earnings per share (“EPS”) is calculated by dividing net income (loss) attributable to the Company’s common shareholders by the weighted average number of common shares outstanding for the period including participating securities (restricted shares issued pursuant to the Company’s share-based compensation program are considered participating securities, as such shares have non-forfeitable rights to receive dividends). Unvested restricted shares are not allocated net losses and/or any excess of dividends declared over net income, as such amounts are allocated entirely to the common shareholders. For 2016, 2015 and 2014, the Company had 3.6 million, 3.5 million and 3.7 million, respectively, of weighted average unvested restricted shares outstanding. The following table provides a reconciliation of the numerator and denominator of the EPS calculations for the 2016, 2015 and 2014, respectively: Years ended December 31, 2016 2015 2014 Numerator Income from continuing operations $ 8,764,000 $ 21,616,000 $ 17,611,000 Preferred stock dividends (14,408,000 ) (14,408,000 ) (14,408,000 ) Net loss attributable to noncontrolling interests 179,000 366,000 358,000 Net earnings allocated to unvested shares (715,000 ) (701,000 ) (734,000 ) (Loss) income from continuing operations attributable to vested common shares (6,180,000 ) 6,873,000 2,827,000 Income from discontinued operations, net of noncontrolling interests, attributable to vested common shares - 164,000 11,012,000 Net (loss) income attributable to vested common shares outstanding $ (6,180,000 ) $ 7,037,000 $ 13,839,000 Denominator Weighted average number of vested common shares outstanding 81,672,000 81,356,000 75,311,000 Earnings per vested common share, basic and diluted Continuing operations $ (0.08 ) $ 0.09 $ 0.04 Discontinued operations 0.00 0.00 0.14 $ (0.08 ) $ 0.09 $ 0.18 Fully-diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into shares of common stock. The 5,750,000 common shares subject to the forward sale agreements (see Note 12 - “Shareholders’ Equity”) have been excluded from the denominator as they were anti-dilutive using the treasury stock method .

Accounting Policies [Abstract]
Principles Of Consolidation/Basis of Preparation	Principles of Consolidation/Basis of Preparation The consolidated financial statements include the accounts and operations of the Company, the Operating Partnership, its subsidiaries, and certain joint venture partnerships in which it participates. The Company consolidates all variable interest entities (“VIEs”) for which it is the primary beneficiary. Generally, a VIE is an entity with one or more of the following characteristics: (1) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional subordinated financial support, (2) as a group, the holders of the equity investment at risk (a) lack the power through voting or similar rights to make decisions about the entity’s activities that significantly impact the entity’s performance, (b) have no obligation to absorb the expected losses of the entity, or (c) have no right to receive the expected residual returns of the entity, or (3) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity’s activities either involve, or are conducted on behalf of, an investor that has disproportionately fewer voting rights. Significant judgments related to these determinations include estimates about the current and future fair values, performance of real estate held by these VIEs, and general market conditions. In February 2015, the Financial Accounting Standards Board (“FASB”) issued guidance which amends the consolidation requirements, including introducing a separate consolidation analysis specific to limited partnerships and other similar entities. Under the analysis, limited partnerships and other similar entities will be considered variable interest entities unless the limited partners hold substantive kick-out rights or participating rights. The guidance was adopted on January 1, 2016. The Company evaluated its existing joint venture property at San Souci Plaza based on the new guidance, determined the entity is now deemed to be a variable interest entity, and will continue to consolidate the entity. At December 31, 2016, this VIE owned real estate with a carrying value of $26.2 million and no mortgage loan payable. The Company has a 60%-owned joint venture originally formed to develop the project known as Crossroads II. This joint venture is consolidated as it is deemed to be a VIE and the Company is the primary beneficiary. The Company (1) guaranteed all related debt, (2) does not require its partners to fund additional capital requirements, (3) has an economic interest greater than its voting proportion and (4) directs the management activities that significantly impact the performance of the joint venture. At December 31, 2016, this VIE owned real estate with a carrying value of $39.2 million and no mortgage loan payable. On January 23, 2015, the Company acquired the New London Mall joint venture partner’s 60% ownership interest, giving the Company a 100% ownership interest in this property, which is located in New London, Connecticut (See Note 3 - “Real Estate”). Prior to the acquisition of the joint venture partner’s ownership interest, the entity was not a VIE, the Company was the sole general partner and exercised substantial operating control over the entity; accordingly, the Company determined that the entity should be consolidated. The accompanying financial statements are prepared on the accrual basis in accordance with accounting principles generally accepted in the United States (“GAAP”), which requires management to make estimates and assumptions that affect the disclosure of contingent assets and liabilities, the reported amounts of assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the periods covered by the financial statements. Actual results could differ from these estimates.

The provision for depreciation is calculated using the straight-line method based upon the estimated useful lives of the respective assets of between 3 and 40 years, with buildings being depreciated at the upper end of the range. Depreciation expense amounted to $37.1 million, $35.0 million and $35.0 million for 2016, 2015 and 2014, respectively. Expenditures for betterments that substantially extend the useful lives of the assets are capitalized. Expenditures for maintenance, repairs, and betterments that do not substantially prolong the normal useful life of an asset are charged to operations as incurred. Real estate investments include costs of ground-up development and redevelopment activities, and construction in progress. Capitalized costs, including interest and other carrying costs during the construction and/or renovation periods, are included in the cost of the related asset and charged to operations through depreciation over the asset’s estimated useful life. A variety of costs are incurred in the development and leasing of a property, such as 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. After a determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. The Company ceases capitalization on the portions substantially completed and occupied, or held available for occupancy, and capitalizes only those costs associated with the portions under development. The Company considers a construction project to be substantially completed and held available for occupancy upon the completion of tenant improvements, but not later than one year from cessation of major construction activity. The Company allocates the fair value of real estate acquired to land, buildings and improvements. In addition, the fair value of in-place leases is allocated to intangible lease assets and liabilities. The fair value of the tangible assets of an acquired property is determined by valuing the property as if it were vacant, which value is then allocated to land, buildings and improvements based on management’s determination of the fair values of these assets. In valuing an acquired property’s intangibles, factors considered by management include an estimate of carrying costs during the expected lease-up periods, such as real estate taxes, insurance, other operating expenses, and estimates of lost rental revenue during the expected lease-up periods based on its evaluation of current market demand. Management also estimates costs to execute similar leases, including leasing commissions, tenant improvements, legal and other related costs. The values of acquired above-market and below-market leases are recorded based on the present values (using discount rates which reflect the risks associated with the leases acquired) of the differences between the contractual amounts to be received and management’s estimate of market lease rates, measured over the terms of the respective leases that management deemed appropriate at the time of the acquisitions. Such valuations include consideration of the non-cancellable terms of the respective leases as well as any applicable renewal periods. The fair values associated with below-market rental renewal options are determined based on the Company’s experience and the relevant facts and circumstances that existed at the time of the acquisitions. The values of above-market leases are amortized to rental income over the terms of the respective non-cancelable lease periods. The portion of the values of below-market leases associated with the original non-cancelable lease terms are amortized to rental income over the terms of the respective non-cancelable lease periods. The portion of the values of the leases associated with below-market renewal options that are likely of exercise are amortized to rental income over the respective renewal periods. The value of other intangible assets (including leasing commissions, tenant improvements, etc.) is amortized to expense over the applicable terms of the respective leases. If a lease were to be terminated prior to its stated expiration or not renewed, all unamortized amounts relating to that lease would be recognized in operations at that time. Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability of real estate investments held for use is based on an estimate of the future cash flows that are expected to result from the real estate investment’s use and eventual disposition. These cash flows consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, capital expenditures, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Sales of real estate are recognized only when sufficient down payments have been obtained, possession and other attributes of ownership have been transferred to the buyer and the Company has no significant continuing involvement. The Company believes these criteria were met for all real estate sold during 2016, 2015 and 2014.
Properties Held For Sale	Properties Held For Sale The Company follows the guidance for reporting discontinued operations, whereby a disposal of an individual property or group of properties is required to be reported in “discontinued operations” only if the disposal represents a strategic shift that has, or will have, a major effect on the Company’s operations and financial results. The results of operations for those properties not meeting such criteria are reported in “continuing operations” in the consolidated statements of operations. The provisions of the guidance were applied prospectively, i.e., for properties classified as “held for sale” subsequent to December 31, 2013. The results of operations for all properties classified as “held for sale” prior to the adoption of the guidance were reported as “discontinued operations” in the consolidated statements of operations. The carrying values of the assets and liabilities of properties determined to be held for sale, principally the net book values of the real estate and the related mortgage loans payable expected to be assumed by the buyers, are reclassified as “held for sale” on the Company’s consolidated balance sheets at the time such determinations are made, on a prospective basis only. In addition, the Company anticipates that sales of all such properties remaining classified as “held for sale” at the balance sheet date will be concluded within one year from such date. The Company conducts a continuing review of the values for all properties “held for sale” based on final sales prices and sales contracts entered into. Impairment charges/reversals, if applicable, are based on a comparison of the carrying values of the properties with either (1) actual sales prices less costs to sell for properties sold, or contract amounts for properties in the process of being sold, (2) estimated sales prices, less costs to sell, based on discounted cash flow analyses, if no contract amounts were as yet being negotiated (see Note 5 — “Fair Value Measurements”), or (3) with respect to land parcels, estimated sales prices, less costs to sell, based on comparable sales completed in the selected market areas. Prior to the Company’s determination to dispose of properties, which are subsequently reclassified to “held for sale”, the Company performed recoverability analyses based on the estimated undiscounted cash flows that were expected to result from the real estate investments’ use and eventual disposal. The projected undiscounted cash flows of each property reflects that the carrying value of each real estate investment would be recovered. However, as a result of the properties’ meeting the “held for sale” criteria, such properties were written down to the lower of their carrying value and estimated fair values less costs to sell.
Cash And Cash Equivalents / Restricted Cash	Cash and Cash Equivalents / Restricted Cash Cash and cash equivalents consist of cash in banks and short-term investments with original maturities when purchased of less than ninety days, and include cash at consolidated joint ventures of $0.5 million and $0.2 million at December 31, 2016 and 2015, respectively. The terms of several of the Company’s mortgage loans payable require the Company to deposit certain replacement and other reserves with its lenders. Such “restricted cash” is generally available only for property-level requirements for which the reserves have been established.
Fair Value Measurements	Fair Value Measurements The accounting guidance for fair value measurement establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three levels: • Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets. • Level 2 – Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. • Level 3 – Inputs to the valuation methodology are unobservable and significant to the fair value measurement. The fair value hierarchy gives the highest priority to Level 1 inputs and the lowest priority to Level 3 inputs. In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible while also considering counterparty credit risk in the assessment of fair value.
Revenue Recognition And Receivables	Revenue Recognition and Receivables Management has determined that all of the Company’s leases with its various tenants are operating leases. Rental income with scheduled rent increases is recognized using the straight-line method over the respective non-cancelable terms of the leases. The aggregate excess of rental revenue recognized on a straight-line basis over the contractual base rents is included in receivables on the consolidated balance sheet. Leases also generally contain provisions under which the tenants reimburse the Company for a portion of property operating expenses and real estate taxes incurred, generally attributable to their respective allocable portions of gross leasable area. Such income is recognized in the periods earned. In addition, a limited number of operating leases contain contingent rent provisions under which tenants are required to pay, as additional rent, a percentage of their sales in excess of a specified amount. The Company defers recognition of contingent rental income until those specified sales targets are met. Revenues also include items such as lease termination fees, which tend to fluctuate more than rents from year to year. Termination fees are fees that the Company has agreed to accept in consideration for permitting certain tenants to terminate their lease prior to the contractual expiration. The Company recognizes lease termination income when the following conditions are met: (1) the lease termination agreement has been executed, (2) the lease termination fee is determinable, (3) all the Company’s landlord services pursuant to the terminated lease have been rendered, and (4) collectability of the lease termination fee is assured. The Company must make estimates as to the collectability of its accounts receivable related to base rent, straight-line rent, percentage rent, expense reimbursements and other revenues. When management analyzes accounts receivable and evaluates the adequacy of the allowance for doubtful accounts, it considers such things as historical bad debts, tenant creditworthiness, current economic trends, current developments relevant to a tenant’s business specifically and to its business category generally, and changes in tenants’ payment patterns. The allowance for doubtful accounts was $4.7 million and $4.4 million at December 31, 2016 and 2015, respectively. The provision for doubtful accounts (included in operating, maintenance and management expenses) was $1.2 million, $1.4 million and $1.9 million in 2016, 2015 and 2014, respectively.

Income Taxes	Income Taxes The Company, organized in 1984, has elected to be taxed as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). A REIT will generally not be subject to federal income taxation on that portion of its income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of such REIT taxable income to its shareholders and complies with certain other requirements. As of December 31, 2016, the Company was in compliance with all REIT requirements. The Company follows a two-step approach for evaluating uncertain federal, state and local tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that more-likely-than-not will be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. The Company has not identified any uncertain tax positions which would require an accrual.
Derivative Financial Instruments	Derivative Financial Instruments The Company occasionally utilizes derivative financial instruments, principally interest rate swaps, to manage its exposure to fluctuations in interest rates. The Company has established policies and procedures for risk assessment, and the approval, reporting and monitoring of derivative financial instruments. Derivative financial instruments must be effective in reducing the Company’s interest rate risk exposure in order to qualify for hedge accounting. When the terms of an underlying transaction are modified, or when the underlying hedged item ceases to exist, all changes in the fair value of the instrument are marked-to-market with changes in value included in net income for each period until the derivative financial instrument matures or is settled. Any derivative financial instrument used for risk management that does not meet the hedging criteria is marked-to-market with the changes in value included in net income. The Company has not entered into, and does not plan to enter into, derivative financial instruments for trading or speculative purposes.
Share-Based Compensation	Share-Based Compensation The Company’s 2012 Stock Incentive Plan (the “2012 Plan”) establishes the procedures for the granting of, among other things, restricted stock awards. The maximum number of shares of the Company’s common stock that may be issued pursuant to the 2012 Plan is 4.5 million (see Note 15 – “Share-Based Compensation”), and the maximum number of shares that may be granted to a participant in any calendar year may not exceed 500,000. All grants issued pursuant to the 2012 Plan generally vest (1) at the end of designated time periods for time-based grants, or (2) upon the completion of a designated period of performance for performance-based grants and satisfaction of performance criteria. Time–based grants are valued according to the market price for the Company’s common stock at the date of grant. For performance-based grants, the Company generally engages an independent appraisal company to determine the value of the shares at the date of grant, taking into account the underlying contingency risks associated with the performance criteria. The value of all grants are being expensed on a straight-line basis over their respective vesting periods (irrespective of achievement of the performance-based grants) adjusted, as applicable, for forfeitures. For restricted share grants subject to graded vesting, the amounts expensed are at least equal to the measured expense of each vested tranche. Based on the terms of the 2012 Plan, those grants of restricted shares that are contributed to the Rabbi Trusts are classified as treasury stock on the Company’s consolidated balance sheet.

Recently-Issued Accounting Pronouncements	Recently-Issued Accounting Pronouncements In May 2014, the FASB issued guidance which amends the accounting for revenue recognition. Under the amended guidance, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled to and receive in exchange for those goods or services. Leases are specifically excluded from this guidance and will be governed by the applicable lease codification; however, this update may have implications with respect to certain variable payment terms included in lease agreements. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption not permitted. The Company is currently in the process of evaluating the guidance; however, based on its initial assessment, the Company does not believe it will have a material impact on its consolidated financial statements. In August 2014, the FASB issued guidance which requires management to evaluate whether there are conditions and events that raise substantial doubt about an entity’s ability to continue as a going concern, and to provide disclosures when it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued. The guidance was adopted on January 1, 2016 and did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued guidance which amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. The guidance requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than twelve months regardless of their classification. Leases with a term of twelve months or less will be accounted for pursuant to existing guidance for operating leases. The guidance is expected to result in the recognition of a right-to-use asset and related liability to account for the Company’s future obligations under its ground lease and executive office lease agreements for which the Company is the lessee. As of December 31, 2016, the remaining contractual payments under the Company’s ground lease and executive office lease agreements aggregated $17.1 million with a remaining weighted average term of 46.1 years. Additionally, the guidance will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under this guidance, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. Lessors will continue to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases, and operating leases. In March 2016, the FASB issued guidance which amends the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2016, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In June 2016, the FASB issued guidance which enhances the methodology of measuring expected credit losses to include the use of forward-looking information to better calculate credit loss estimates. The guidance will apply to most financial assets measured at amortized cost and certain other instruments, including accounts receivable, straight-line rent receivables, loans, held-to-maturity debt securities, net investments in leases, and off-balance-sheet credit exposures. The guidance will require that the Company estimate the lifetime expected credit loss with respect to these receivables and record allowances that, when deducted from the balance of the receivables, represent the net amounts expected to be collected. The Company will also be required to disclose information about how it developed the allowances, including changes in the factors that influenced the Company’s estimate of expected credit losses and the reasons for those changes. In August 2016, the FASB issued guidance that clarifies how an entity should classify certain cash receipts and cash payments on its statement of cash flows. The guidance established that an entity will classify cash payments for debt prepayment or extinguishment costs as financing cash flows. In addition, the guidance provides entities with an alternative to consider regarding the nature of the source of distributions that an investor receives from an equity method investment when classifying distributions received in its cash flow statement (the nature of the distribution approach). Alternatively, entities can elect to classify the distributions received from equity method investees based on the cumulative earnings approach. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued guidance that will require entities to show the changes in the total of cash, cash equivalents and restricted cash in the statement of cash flows. When cash, cash equivalents and restricted cash are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has evaluated the guidance and has determined it will not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued guidance which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are described in the guidance on revenue from contracts with customers. The Company believes that most of its typical acquisitions of real estate will not meet the new definition of a business, and accordingly, will result in the capitalization of associated acquisition pursuit costs. The guidance would be effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption being permitted. The Company has elected to early adopt this guidance effective January 1, 2017.
