Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Insurance The Company carries comprehensive liability, fire, extended coverage, business interruption and rental loss insurance covering all of the properties in its portfolio under an insurance policy, in addition to other coverages, such as trademark and pollution coverage that may be appropriate for certain of its properties. Additionally, the Company carries a directors’, officers’, entity and employment practices liability insurance policy that covers such claims made against the Company and its directors and officers. The Company believes the policy specifications and insured limits are appropriate and adequate for its properties given the relative risk of loss, the cost of the coverage and industry practice; however, its insurance coverage may not be sufficient to fully cover its losses. Concentration of Credit Risk The Company is subject to risks incidental to the ownership and operation of commercial real estate. These risks include, among others, the risks normally associated with changes in the general economic climate, trends in the retail industry, creditworthiness of tenants, competition for tenants and customers, changes in tax laws, interest rates, the availability of financing and potential liability under environmental and other laws. The Company’s portfolio of properties is dependent upon regional and local economic conditions and is geographically located in the Southeast, Mid-Atlantic and Northeast, which markets represented approximately 62%, 34% and 4%, respectively, of the total annualized base rent of the properties in its portfolio as of December 31, 2021. The Company’s geographic concentration may cause it to be more susceptible to adverse developments in those markets than if it owned a more geographically diverse portfolio. Additionally, the Company’s retail shopping center properties depend on anchor stores or major tenants to attract shoppers and could be adversely affected by the loss of, or a store closure by, one or more of these tenants. Regulatory and Environmental As the owner of the buildings on our properties, the Company could face liability for the presence of hazardous materials (e.g., asbestos or lead) or other adverse conditions (e.g., poor indoor air quality) in its buildings. Environmental laws govern the presence, maintenance, and removal of hazardous materials in buildings, and if the Company does not comply with such laws, it could face fines for such noncompliance. Also, the Company could be liable to third parties (e.g., occupants of the buildings) for damages related to exposure to hazardous materials or adverse conditions in its buildings, and the Company could incur material expenses with respect to abatement or remediation of hazardous materials or other adverse conditions in its buildings. In addition, some of the Company’s tenants routinely handle and use hazardous or regulated substances and wastes as part of their operations at our properties, which are subject to regulation. Such environmental and health and safety laws and regulations could subject the Company or its tenants to liability resulting from these activities. Environmental liabilities could affect a tenant’s ability to make rental payments to the Company, and changes in laws could increase the potential liability for noncompliance. This may result in significant unanticipated expenditures or may otherwise materially and adversely affect the Company’s operations. The Company is not aware of any material contingent liabilities, regulatory matters or environmental matters that may exist. Litigation The Company is involved in various legal proceedings arising in the ordinary course of its business, including, but not limited to commercial disputes. The Company believes that such litigation, claims and administrative proceedings will not have a material adverse impact on its financial position or its results of operations. The Company records a liability when it considers the loss probable and the amount can be reasonably estimated. In addition, the below legal proceedings are in process. Jon Wheeler v. Wheeler Real Estate Investment Trust, Inc., Circuit Court for the City of Virginia Beach, Virginia. Former CEO, Jon Wheeler, alleged that his employment was improperly terminated and that he was owed severance and bonus payments pursuant to his Employment Agreement. In 2020, The Court found in favor of Jon Wheeler on his claim that his employment was terminated without cause. The Court denied Mr. Wheeler’s claims for a bonus and that his termination of employment was wrongful as a violation of public policy. The Court awarded the Company $5 thousand on its counterclaim. At a hearing on September 4, 2020 on Jon Wheeler’s motion for the award of attorneys’ fees, costs, and pre-judgment interest, the Court awarded Mr. Wheeler the requested costs, but awarded no attorneys’ fees and no pre-judgment interest. In total, Mr. Wheeler was awarded $520 thousand. In October 2020, the Company settled with Mr. Wheeler for $500 thousand. Mr. Wheeler preserved his right to appeal the Court’s denial of an award of attorneys’ fees of $375 thousand and pre-judgment interest of $63 thousand. On June 16, 2021, the Supreme Court granted Mr. Wheeler an appeal on his first assignment of error (i.e., the Circuit Court’s refusal to award Mr. Wheeler any attorneys’ fees) but denied the appeal as to Mr. Wheeler’s claim for prejudgment interest. The parties settled in the amount of $185 thousand on July 28, 2021. David Kelly v. Wheeler Real Estate Investment Trust, Inc., Circuit Court for the City of Virginia Beach, Virginia. Former CEO David Kelly filed suit on May 28, 2020, alleging breach of his employment contract. Mr. Kelly claims that his employment was improperly terminated, that he is owed severance pay and related benefits pursuant to his employment agreement, and seeks damages of $400 thousand, plus unpaid bonuses and benefits, pre- and post-judgment interest, attorneys’ fees, and costs. The Company is defending the action on the grounds that Mr. Kelly’s employment was properly terminated for cause and no severance is owed to him. Trial is set for March 2022. At this juncture, the outcome of the matter cannot be predicted. JCP Investment Partnership LP, et al v. Wheeler Real Estate Investment Trust, Inc., United States District Court for the District of Maryland. On March 22, 2021, JCP Investment Partnership, LP, a Texas limited partnership and stockholder of the Company, JCP Investment Partners, LP, a Texas limited partnership and stockholder of the Company, JCP Investment Holdings, LLC, a Texas limited liability company and stockholder of the Company, and JCP Investment Management, LLC, a Texas limited liability company and stockholder of the Company (collectively, the “JCP Plaintiffs”), filed suit against the Company and certain current and former directors and former officers of the Company (the “Individual Defendants”), in the United States District Court for the District of Maryland. The complaint alleges that the Company amended provisions of its Articles Supplementary in 2018 governing the issuance of the Company’s Series D Preferred in violation of Maryland corporate law and without obtaining the consent of preferred stockholders and, therefore, the court should declare the Company’s said amendment invalid, enjoin further purportedly unauthorized amendments, and either compel the Company to redeem the JCP Plaintiffs' stock or enter judgment for monetary damages the JCP Plaintiffs purportedly sustained based on the Company’s alleged breach of its contractual duties to redeem the JCP Plaintiffs’ Series D Preferred. The complaint also alleges certain violations of Section 10(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated thereunder, and alleges that the Individual Defendants violated Section 20(a) of the Exchange Act. The JCP Plaintiffs are each purportedly a holder of the Company’s Series D Preferred. The complaint seeks damages, interest, attorneys’ fees, other costs and expenses, and such other relief as the court may deem just and equitable. The Company has filed an answer to the complaint denying any liability. The Individual Defendants filed a motion to dismiss the complaint, which was denied. The JCP Plaintiffs have filed a Motion For Partial Summary Judgment, as to which the Company and the Individual Defendants filed oppositions. The Court has not yet ruled on the Motion. At this early juncture, the outcome of the litigation is uncertain. Steamboat Capital Partners Master Fund, LP and Steamboat Capital Partners II, LP v. Wheeler Real Estate Investment Trust, Inc., Steamboat Capital Partners Master Fund, LP and Steamboat Capital Partners II, LP v. Wheeler Real Estate Investment Trust, Inc., Circuit Court for Baltimore County, Maryland. On October 25, 2021, Steamboat Capital Partners Master Fund, LP, a Cayman Islands exempted limited partnership and stockholder of the Company, and Steamboat Capital Partners II, LP, a Delaware limited partnership and stockholder of the Company, filed suit against the Company in the Circuit Court for Baltimore County, Maryland. The complaint alleges that the Company's rights offering of convertible debt to the Company's common stockholders, and the notes issued pursuant to the rights offering, breached the provisions of the Company's governing documents and violated the rights of the holders of the Series B Preferred and Series D Preferred. Plaintiffs seek relief as follows: require the Company to pay all dividends accrued, as of the date of the rights offering, on the Series B Preferred and Series D Preferred, and prohibit the Company from paying interest on the notes held by the Company's common stockholders (upon exercise of the rights) until all accrued dividends on the Series B Preferred and Series D Preferred are paid. Plaintiffs also seek a declaration that the rights offering by the Company to its common stockholders, which resulted in the issuance of notes, when accrued Series B Preferred dividends and Series D Preferred dividends had not been fully paid, breached the provisions of the Company's governing documents. In addition, the complaint contends that the Company's amendment of its charter to remove the cumulative nature of dividends from the Series B Preferred cannot be applied retroactively. A trial date is set for May 2023. At this juncture, the outcome of the matter cannot be predicted. Harbor Pointe Tax Increment Financing On September 1, 2011, the Grove Economic Development Authority issued the Grove Economic Development Authority Tax Increment Revenue Note, Taxable Series 2011 in the amount of $2.42 million, bearing a variable interest rate of 2.29%, not to exceed 14% and payable in 50 semi-annual installments. The proceeds of the bonds were to provide funding for the construction of public infrastructure and other site improvements and to be repaid by incremental additional property taxes generated by development. Harbor Pointe Associates, LLC, then owned by an affiliate of former CEO, Jon Wheeler, entered into an Economic Development Agreement with the Grove Economic Development Authority for this infrastructure development and in the event the ad valorem taxes were insufficient to cover annual debt service, Harbor Pointe Associates, LLC would reimburse the Grove Economic Development Authority (the “Harbor Pointe Agreement”). In 2014, Harbor Pointe Associates, LLC was acquired by the Company. The total debt service shortfall over the life of the bond is uncertain as it is based on ad valorem taxes, assessed property values, property tax rates, LIBOR and future potential development ranging until 2036. The Company’s future total principal obligation under the Harbor Pointe Agreement will be no more than $2.11 million, the principal amount of the bonds, as of December 31, 2021. In addition, the Company may have an interest obligation on the note based on the principal balance and LIBOR rates in effect at future payment dates. The Company funded approximately $87 thousand and $0 thousand, during the years ended December 31, 2021 and 2020, respectively, in debt service shortfalls. No amounts have been accrued for this as of December 31, 2021 as a reasonable estimate of future debt service shortfalls cannot be determined based on variables noted above. Tax Protection Agreement In 2016, in connection with the acquisition of Berkley and Sangaree/Tri-County, the Operating Partnership entered into a tax protection agreement that obligates the Operating Partnership to reimburse Jon Wheeler, the Company's former CEO, for his tax liabilities resulting from the recognition of certain taxable income or gain in the event the Operating Partnership takes certain action prior to November 10, 2023 with respect to Sangaree Plaza, Tri-County Plaza and Berkley. No liability was recorded as of December 31, 2021.
