Contingencies [Abstract]
Contingencies	11. Contingencies Contingent Liability In February 2021, the Company entered into an agreement with SDG&E to provide 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County for a total payment of $50.0 million. The SDG&E Agreement will support SDG&E’s deployment of a private LTE network for its California service territory, with a population of approximately 3.6 million people. As part of the SDG&E Agreement, the Company and SDG&E are collaborating to accelerate the utility industry momentum for private networks. The SDG&E Agreement includes the assignment of 6 MHz of 900 MHz Broadband Spectrum, 936.5 – 939.5 MHz paired with 897.5 – 900.5 MHz, within SDG&E’s service territory following the FCC’s issuance of the broadband licenses to the Company. Delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses by county is expected to commence in fiscal year 2023 and is scheduled for completion before the end of fiscal year 2024. The total payment of $50.0 million is comprised of an initial payment of $20.0 million received in February 2021 and the remaining $30.0 million payment, which is due through fiscal year 2024 as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. The Company is working with incumbents to clear the 900 MHz Broadband Spectrum allocation in the SDG&E’s California service territory. The SDG&E Agreement is subject to customary provisions regarding remedies, including reduced payment amounts and/or refund of amounts paid, and termination rights, if a party fails to perform its contractual obligations. Both SDG&E and Anterix obtained all necessary internal approvals prior to executing the SDG&E Agreement. A gain or loss will be recognized in each county once the cleared 900 MHz Broadband Spectrum and the associated broadband licenses are delivered to SDG&E. As the Company is required to refund the initial payment in the event of termination or non-delivery of the 900 MHz Broadband Spectrum, it recorded $20.0 million for the upfront payment received from SDG&E in February 2021 as contingent liability in the Consolidated Balance Sheet as of March 31, 2021. There was no additional contingent liability incurred for the quarter ended September 30, 2021. Litigation From time to time, the Company may be involved in litigation that arises from the ordinary operations of the business, such as contractual or employment disputes or other general actions. The Company is not involved in any material legal proceedings at this time. COVID-19 Pandemic In March 2020, the World Health Organization declared the outbreak of a novel coronavirus (“COVID-19”) as a pandemic and COVID-19 continues to cause significant disruptions throughout the United States. The Company instituted numerous precautionary measures intended to help ensure the well-being as majority of the Company’s employees continue to work from home, remotely negotiate and work with customers, covered incumbents and the FCC. Virtually all employees remain subject to travel restrictions and access to the Company’s premises is restricted. The Company will continue to closely monitor the risks posed by COVID-19 and adjust its practices accordingly. In order to manage the financial impact caused by the pandemic, the Company also deferred payroll taxes under the CARES Act amounting to approximately $0.3 million as of September 30, 2021. As a result of prioritizing the use of our cash and measures implemented, no significant adverse impact on our results of operations through and financial position as of September 30, 2021, has occurred as a result of the pandemic. The ultimate extent of the impact of COVID-19 on future financial performance of the Company and its ability to secure broadband licenses pursuant to the terms of the 900 MHz Report and Order and to commercialize any broadband licenses it secures, will depend on ongoing developments, including the duration and further spread of COVID-19, the laws, orders and restrictions imposed by federal, state and local governmental agencies, and the overall economy, all of which remain uncertain and cannot be predicted. If the financial markets and/or the overall economy are impacted for an extended period, the Company's operating results may be materially and adversely affected. The Company is managing its cash flow and believes that it has adequate liquidity.
