Accounting Policies [Abstract]
Investment Properties	Investment Properties The Company records investment properties and related intangibles at fair value upon acquisition. Investment properties include both acquired and constructed assets. Improvements and major repairs and maintenance are capitalized when the repair and maintenance substantially extends the useful life, increases capacity or improves the efficiency of the asset. All other repair and maintenance costs are expensed as incurred. The Company capitalizes interest on projects during periods of construction until the projects reach the completion point that corresponds with their intended purpose. The Company allocates the purchase price of acquisitions to the various components of the asset based upon the fair value of each component which may be derived from various observable or unobservable inputs and assumptions. Also, the Company may utilize third party valuation specialists. These components typically include buildings, land and any intangible assets related to out-of-market leases, tenant relationships and in-place leases the Company determines to exist. The Company determines fair value based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends and specific market and economic conditions that may affect the property. Factors considered by management in the analysis of determining the as-if-vacant property value include an estimate of carrying costs during the expected lease-up periods considering market conditions, and costs to execute similar leases. In estimating carrying costs, management includes real estate taxes, insurance and estimates of lost rentals at market rates during the expected lease-up periods, tenant demand and other economic conditions. Management also estimates costs to execute similar leases including leasing commissions, tenant improvements, legal and other related expenses. Intangibles related to out-of-market leases, tenant relationships and in-place lease value are recorded at fair value as acquired lease intangibles and are amortized as an adjustment to rental revenue or amortization expense, as appropriate, over the remaining terms of the underlying leases. Premiums or discounts on acquired out-of-market debt are amortized to interest expense over the remaining term of such debt. The Company records depreciation on buildings and improvements utilizing the straight-line method over the estimated useful life of the asset, generally 5 to 40 years. The Company reviews depreciable lives of investment properties periodically and makes adjustments to reflect a shorter economic life, when necessary. Tenant allowances, tenant inducements and tenant improvements are amortized utilizing the straight-line method over the term of the related lease or occupancy term of the tenant, if shorter. Amounts allocated to buildings are depreciated over the estimated remaining life of the acquired building or related improvements. The Company amortizes amounts allocated to tenant improvements, in-place lease assets and other lease-related intangibles over the remaining life of the underlying leases. The Company also estimates the value of other acquired intangible assets, if any, and amortizes them over the remaining life of the underlying related intangibles. The Company reviews investment properties for impairment on a property-by-property basis whenever events or changes in circumstances indicate that the carrying value of investment properties may not be recoverable, but at least annually. These circumstances include, but are not limited to, declines in the property’s cash flows, occupancy and fair market value. The Company measures any impairment of investment property when the estimated undiscounted operating income before depreciation and amortization, plus its residual value, is less than the carrying value of the property. To the extent impairment has occurred, the Company charges to income the excess of the carrying value of the property over its estimated fair value. The Company estimates fair value using unobservable data such as operating income, estimated capitalization rates, or multiples, leasing prospects and local market information. The Company may decide to sell properties that are held for use and the sale prices of these properties may differ from their carrying values. The Company did not record any impairment adjustments to its properties during the years ended December 31, 2016, 2015 and 2014.
Conditional Asset Retirement Obligation	Conditional Asset Retirement Obligation A conditional asset retirement obligation represents a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement depends on a future event that may or may not be with the Company’s control. Currently, the Company does not have any conditional asset retirement obligations. However, any such obligations identified in the future would result in the Company recording a liability if the fair value of the obligation can be reasonably estimated. Environmental studies conducted at the time the Company acquired its properties did not reveal any material environmental liabilities, and the Company is unaware of any subsequent environmental matters that would have created a material liability. The Company believes that its properties are currently in material compliance with applicable environmental, as well as non-environmental, statutory and regulatory requirements. The Company did not record any conditional asset retirement obligation liabilities during the years ended December 31, 2016, 2015 and 2014.
Cash and Cash Equivalents	Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents consist primarily of bank operating accounts and money markets. Financial instruments that potentially subject the Company to concentrations of credit risk include its cash and cash equivalents and its trade accounts receivable. The Company places its cash and cash equivalents with institutions of high credit quality. Restricted cash represents amounts held by lenders for real estate taxes, insurance, reserves for capital improvements and tenant security deposits. The Company presents changes in cash restricted for real estate taxes, insurance and tenant security deposits as operating activities in the consolidated statement of cash flows. The Company presents changes in cash restricted for capital improvements as investing activities in the consolidated statement of cash flows. The Company places its cash and cash equivalents and restricted cash on deposit with financial institutions in the United States, which are insured by the Federal Deposit Insurance Company ("FDIC") up to $250 thousand.
Tenant Receivables and Unbilled Rent	Tenant Receivables and Unbilled Rent Tenant receivables include base rents, tenant reimbursements and receivables attributable to recording rents on a straight-line basis. The Company determines an allowance for the uncollectible portion of accrued rents and accounts receivable based upon customer credit-worthiness (including expected recovery of a claim with respect to any tenants in bankruptcy), historical bad debt levels, and current economic trends. The Company considers a receivable past due once it becomes delinquent per the terms of the lease. The Company’s standard lease form considers a rent charge past due after five days. A past due receivable triggers certain events such as notices, fees and other allowable and required actions per the lease. As of December 31, 2016 and 2015, the Company’s allowance for uncollectible accounts totaled $691 thousand and $411 thousand, respectively. During the years ended December 31, 2016, 2015 and 2014, the Company recorded provisions for credit losses in the amount of $425 thousand, $243 thousand and $61 thousand, respectively, related to tenant receivables that were specifically identified as potentially uncollectible based on the an assessment of the tenant’s credit-worthiness. During the years ended December 31, 2016, 2015 and 2014, the Company did not realize any recoveries related to tenant receivables previously charged off.
Above and Below Market Lease Intangibles, net	Above and Below Market Lease Intangibles, net The Company determines the above and below market lease intangibles upon acquiring a property. Above and below market lease intangibles are amortized over the life of the respective leases. Amortization of above and below market lease intangibles is recorded as a component of rental revenues.
Deferred Costs and Other Assets	Deferred Costs and Other Assets, net The Company’s deferred costs and other assets consist primarily of leasing commissions, leases in place, capitalized legal and marketing costs and tenant relationship intangibles associated with acquisitions. The Company’s lease origination costs consist primarily of the portion of property acquisitions allocated to lease originations and commissions paid in connection with lease originations.
Revenue Recognition	Revenue Recognition The Company retains substantially all of the risks and benefits of ownership of the investment properties and accounts for its leases as operating leases. The Company accrues minimum rents on a straight-line basis over the terms of the respective leases which results in an unbilled rent asset or deferred rent liability being recorded on the balance sheet. At December 31, 2016 and 2015, there were $1.2 million and $880 thousand in an unbilled rent asset which is included in rents and other tenant receivables, net. Additionally, certain of the lease agreements contain provisions that grant additional rents based on tenants’ sales volumes (contingent or percentage rent). Percentage rents are recognized when the tenants achieve the specified targets as defined in their lease agreements. During the years ended December 31, 2016, 2015 and 2014, the Company recognized percentage rents of $289 thousand, $163 thousand and $90 thousand, respectively. The Company’s leases generally require the tenant to reimburse the Company for a substantial portion of its expenses incurred in operating, maintaining, repairing, insuring and managing the shopping center and common areas (collectively defined as Common Area Maintenance or “CAM” expenses). The Company includes these reimbursements, along with other revenue derived from late fees and seasonal events, under the Consolidated Statements of Operations caption "Tenant reimbursements and other revenues." This significantly reduces the Company’s exposure to increases in costs and operating expenses resulting from inflation or other outside factors. The Company accrues reimbursements from tenants for recoverable portions of all these expenses as revenue in the period the applicable expenditures are incurred. The Company calculates the tenant’s share of operating costs by multiplying the total amount of the operating costs by a fraction, the numerator of which is the total number of square feet being leased by the tenant, and the denominator of which is the average total square footage of all leasable buildings at the property. The Company also receives escrow payments for these reimbursements from substantially all its tenants throughout the year. The Company recognizes differences between estimated recoveries and the final billed amounts in the subsequent year. These differences were not material for the years ended December 31, 2016, 2015 and 2014. The Company recognizes lease termination fees in the period that the lease is terminated and collection of the fees is reasonably assured. Upon early lease termination, the Company provides for losses related to unrecovered intangibles and other assets.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code and applicable Treasury regulations relating to REIT qualification. In order to maintain this REIT status, the regulations require the Company to distribute at least 90% of its taxable income to shareholders and meet certain other asset and income tests, as well as other requirements. The TRS' have accrued $107 thousand for 2016 federal and state income tax expenses. If the Company fails to qualify as a REIT, it will be subject to tax at regular corporate rates for the years in which it fails to qualify. If the Company loses its REIT status it could not elect to be taxed as a REIT for five years unless the Company’s failure to qualify was due to reasonable cause and certain other conditions were satisfied. Management has evaluated the effect of the guidance provided by GAAP on Accounting for Uncertainty of Income Taxes and has determined that the Company had no uncertain income tax positions
Taxable REIT Subsidiary Cost Allocation	Taxable REIT Subsidiary Cost Allocation The Company’s overall philosophy regarding cost allocation centers around the premise that the Trust exists to acquire, lease and manage properties for the benefit of its investors. Accordingly, a majority of the Company’s operations occur at the property level. Each property must carry its own weight by absorbing the costs associated with generating its revenues. Additionally, leases generally allow the Company to pass through to the tenant most of the costs involved in operating the property, including, but not limited to, the direct costs associated with owning and maintaining the property (landscaping, repairs and maintenance, taxes, insurance, etc.), property management and certain administrative costs. Service vendors bill the majority of the direct costs of operating the properties directly to the REIT Properties and Non-REIT Properties and each property pays them accordingly. The Non-REIT Properties pay WRE property management and/or asset management fees of 3% and 2% of collected revenues, respectively. The Non-REIT Properties also pay WRE leasing commissions based on the total contractual revenues to be generated under the new/renewed lease agreement (6% for new leases and 3% for renewals). Non-REIT properties pay development fees of 5% of hard costs. Compensation and benefits paid to employees of the Company represent the largest component of costs incurred to acquire, manage, lease and administer the properties. The Company believes that every employee position exists to either directly or indirectly to perform these functions. Therefore, the Company allocates compensation and benefits to the various functions of the Company based on an estimate of how each employee spends their time. The Company allocates actual costs attributed to property management costs to the TRS on a pro rata basis based on total property revenues generated by the Non-REIT Properties. The Company allocates actual leasing costs to the TRS on a pro rata basis based on total leasing commissions generated by the Non-REIT Properties. Currently, the TRS does not acquire properties for third parties so the Company does not allocate acquisition related costs to the TRS. Additionally, the Company allocates certain other corporate general and administrative expenses associated with generating the TRS' revenues.
Financial Instruments	Financial Instruments The carrying amount of financial instruments included in assets and liabilities approximates fair market value due to their immediate or short-term maturity.
Use of Estimates	Use of Estimates The Company has made estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reported period. The Company’s actual results could differ from these estimates.
Advertising Costs	Advertising Costs The Company expenses advertising and promotion costs as incurred.
Assets Held For Sale	Assets Held For Sale The Company records assets as held for sale when management has committed to a plan to sell the assets, actively seeks a buyer for the assets, and the consummation of the sale is considered probable and is expected within one year.
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests is the portion of equity in the Operating Partnership not attributable to the Trust. The ownership interests not held by the parent are considered noncontrolling interests. Accordingly, noncontrolling interests have been reported in equity on the consolidated balance sheets but separate from the Company’s equity. On the consolidated statements of operations, the subsidiaries are reported at the consolidated amount, including both the amount attributable to the Company and noncontrolling interests. Consolidated statements of changes in equity include beginning balances, activity for the period and ending balances for shareholders’ equity, noncontrolling interests and total equity. The noncontrolling interest of the Operating Partnership common unit holders is calculated by multiplying the noncontrolling interest ownership percentage at the balance sheet date by the Operating Partnership’s net assets (total assets less total liabilities). The noncontrolling interest percentage is calculated at any point in time by dividing the number of units not owned by the Company by the total number of units outstanding. The noncontrolling interest ownership percentage will change as additional units are issued or as units are exchanged for the Company’s $0.01 par value per share Common Stock. In accordance with GAAP, any changes in the value from period to period are charged to additional paid-in capital.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes the revenue recognition requirements of Accounting Standards Codification (“ASC”) Topic 605, “Revenue Recognition” and most industry-specific guidance on revenue recognition throughout the ASC. The new standard is principles based and provides a five step model to determine when and how revenue is recognized. The core principle of the new standard is that revenue should be recognized when a company transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also requires disclosure of qualitative and quantitative information surrounding the amount, nature, timing and uncertainty of revenues and cash flows arising from contracts with customers. In March 2016, the FASB issued ASU No. 2016-08, "Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, "Revenue from contracts with customers (Topic 606): Identifying Performance Obligations and Licensing," which provides further guidance on identifying performance obligations and intellectual property licensing implementation. In June 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients”, which relates to assessing collectability, presentation of sales taxes, noncash consideration and completed contracts and contract modifications in transition. In December 2016, the FASB issued 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers," which clarifies or corrects unintended application of the standard. Companies are permitted to adopt the ASUs as early as fiscal years beginning after December 15, 2016, but the adoption is required for fiscal years beginning after December 15, 2017. These new standards will be effective for the Company in the first quarter of the year ending December 31, 2018 and can be applied either retrospectively to all periods presented or as a cumulative-effect adjustment as of the date of adoption. The Company is currently evaluating the impact of this standard. The majority of the Company’s revenue is based on real estate lease contracts which are not within the scope of this ASU. The Company has identified its non-lease revenue streams and initial analysis indicates the adoption of this standard will not have a material impact on our financial position or results of operations. In August 2014, the FASB issued ASU 2014-15, "Presentation of Financial Statements - Going Concern (Subtopic 205-40)." This ASU defines management's responsibility to evaluate whether there is substantial doubt about an organization's ability to continue as a going concern and provides guidance on required financial statement footnote disclosures. This ASU is effective for annual periods ending after December 15, 2016. The Company adopted this ASU as of December 31, 2016. We added additional disclosures in Note 7 as a result of the adoption of this ASU. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs." This new guidance requires the presentation of unamortized debt issuance costs to be shown in the liabilities section of the consolidated balance sheets as a reduction of the principal amount of the associated debt, rather than as an asset. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015 and early adoption is permitted, including adoption in an interim period. The new standard must be applied using a retrospective approach by restating prior period comparative consolidated balance sheets. The Company adopted the ASU effective January 1, 2016 and applied it on a retrospective basis for all debt issuance costs, including those pertaining to the Company’s revolving credit facility. As a result, unamortized debt issuance costs of $4.71 million as of December 31, 2015, have been reclassified from other assets and presented as a deduction of indebtedness in the consolidated balance sheet. In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." This new guidance requires that the acquirer recognizes adjustments to preliminary acquisition values and account for the cumulative effect of any required adjustments in the period in which they are determined. ASU 2015-16 is effective for fiscal years beginning after December 15, 2015 and early adoption is permitted, including adoption in an interim period. The new standard must be applied using a prospective approach for adjustments that occur after the effective date. The Company adopted the ASU effective January 1, 2016. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 is intended to improve financial reporting about leasing transactions. The ASU affects all companies and other organizations that lease assets such as real estate, airplanes, and manufacturing equipment. The ASU will require organizations that lease assets referred to as “Lessees” to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. An organization is to provide disclosures designed to enable users of financial statements to understand the amount, timing, and uncertainty of cash flows arising from leases. These disclosures include qualitative and quantitative requirements concerning additional information about the amounts recorded in the financial statements. Under the new guidance, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Consistent with current GAAP, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current GAAP which requires only capital leases to be recognized on the balance sheet the new ASU will require both types of leases (i.e. operating and capital) to be recognized on the balance sheet. The FASB lessee accounting model will continue to account for both types of leases. The capital lease will be accounted for in substantially the same manner as capital leases are accounted for under existing GAAP. The operating lease will be accounted for in a manner similar to operating leases under existing GAAP, except that lessees will recognize a lease liability and a lease asset for all of those leases. The leasing standard will be effective for calendar year-end public companies beginning after December 15, 2018. Public companies will be required to adopt the new leasing standard for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption will be permitted for all companies and organizations upon issuance of the standard. For calendar year-end public companies, this means an adoption date of January 1, 2019 and retrospective application to previously issued annual and interim financial statements for 2018 and 2017. Lessees with a large portfolio of leases are likely to see a significant increase in balance sheet assets and liabilities. See Note 10 for the Company’s current lease commitments. The Company is currently evaluating the impact of ASU 2016-02 on its financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” This ASU simplifies several aspects of 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. This ASU is effective for annual periods beginning after December 15, 2016 and early adoption is permitted. The new standard can be applied using either a prospective transition method or a retrospective transition method. The Company will adopt this ASU in 2017 and does not expect the adoption of this ASU to materially impact its financial position or results of operations. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of certain cash receipts and cash payments (a consensus of the Emerging Issues Task Force).” The ASU addresses eight specific cash flow issues in an effort to reduce diversity in practice. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. The new standard is to be applied retrospectively for all period presented. The Company will adopt this ASU in 2018 and does not expect the adoption to materially impact its consolidated statements of cash flows. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force).” The ASU provides guidance on the presentation of restricted cash or restricted cash equivalents in the statement of cash flows in an effort to reduce diversity in practice. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. The new standard is to be applied retrospectively for all period presented. The Company will adopt this ASU in 2018 and does not expect the adoption to materially impact its consolidated statements of cash flows. In January 2017, the FASB issued ASU 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business.” The ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. The new standard is to be applied prospectively. The Company is currently evaluating the impact of ASU-2017-01 on its financial statements. In February 2015, the FASB issued ASU 2015-02 related to ASC Topic 810, “Consolidation (Topic 810): Amendments to the Consolidation Analysis.” This new guidance changes the identification of variable interests, the variable interest entity (“VIE”) characteristics for a limited partnership or similar entity, and primary beneficiary determination. The guidance also eliminates the presumption that a general partner controls a limited partnership. The ASU is effective for annual periods beginning after December 15, 2015. The Company has adopted this ASU with no material impact on the Company’s consolidated financial statements expected. In October 2016, the FASB issued ASU 2016-17, “Consolidation (Topic 810) Interests Held through Related Parties That are under Common Control,” which amends the consolidation guidance on how a reporting entity that is the single decision maker of a VIE should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE and, therefore, consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. The ASU is effective for annual periods beginning after December 15, 2016. The Company will adopt this ASU in 2017 and does not expect the adoption of this ASU to materially impact its financial position or results of operations. In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the test for Goodwill Impairment.” The amendments in ASU 2017-04 eliminate the current two-step approach used to test goodwill for impairment and require an entity to apply a one-step quantitative test and record the amount of goodwill impairment as the excess of a reporting unit's carrying amount over its fair value, not to exceed the total amount of goodwill allocated to the reporting unit. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019 and early adoption is permitted on testing dates after January 1, 2017. The new standard is to be applied prospectively. The Company does not expect the adoption to materially impact its financial position or results of operations. Other accounting standards that have been issued or proposed by the FASB or other standard-setting bodies are not currently applicable to the Company or are not expected to have a significant impact on the Company’s financial position, results of operations and cash flows.
Reclassifications	Reclassifications Certain reclassifications have been made to prior period amounts to make their presentation comparable with the current period. These reclassifications had no impact on net income. During the first quarter of 2016, the Company identified that in previous filings the change in cash restricted for property reserves and payments for deferred financing costs had been reported as cash flows from operating activities and should have been presented as investing and financing activities, respectively. In the third quarter of 2016, the Company reclassed payments to related parties from financing to operating activities. The Company corrected the previously presented cash flows for these items in the current presentation and in doing so, the consolidated statements of cash flows for the year ended December 31, 2015 has been adjusted to increase net cash flows from operating activities by $3.98 million with corresponding decreases in net cash flows from investing and financing activities of $1.93 million and $2.75 million, respectively. For the year ended December 31, 2014, the consolidated statements of cash flows has been adjusted to increase net cash flows from operating activities by $1.97 million with corresponding decreases in net cash flows from investing and financing activities of $1.43 million and $0.57 million, respectively. The Company has evaluated the effect of the incorrect presentation in prior periods, both qualitatively and quantitatively, and concluded that it did not have a material impact on, nor require amendment of, any previously filed annual or quarterly consolidated financial statements.
