Contingencies	14. Contingencies Contingent Liability In February 2021, the Company entered into the SDG&E Agreement to provide 900 MHz broadband spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County. 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 intend to collaborate on accelerating utility industry momentum for private networks. The SDG&E Agreement include the assignment of 6 MHz of broadband spectrum, 936.5 – 939.5 MHz paired with 897.5 – 900.5 MHz, within SDG&E’s service territory following FCC’s issuance of broadband licenses to the Company. Delivery of the broadband spectrum by county is expected to commence in fiscal year 2023 and completed before the end of fiscal 2024. The Company has been proactively working with incumbents to clear the 900 MHz broadband allocation in the SDG&E service territory. Total payment of $50.0 million is comprised of an initial payment of $20.0 million and the remaining $30.0 million is due through fiscal 2024 as broadband spectrum is provided to SDG&E upon clearing of the 900 MHz incumbents by the Company and the granting of broadband licenses by the FCC. As the Company is required to refund the initial payment in the event of termination or non-delivery of the 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. Litigation In addition to commitments and obligations in the ordinary course of business as reflected in the lease footnote above, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of a material adverse outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.

Contingent Liability

In February 2021, the Company entered into the SDG&E Agreement to provide 900 MHz broadband spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County. 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 intend to collaborate on accelerating utility industry momentum for private networks. The SDG&E Agreement include the assignment of 6 MHz of broadband spectrum, 936.5 – 939.5 MHz paired with 897.5 – 900.5 MHz, within SDG&E’s service territory following FCC’s issuance of broadband licenses to the Company. Delivery of the broadband spectrum by county is expected to commence in fiscal year 2023 and completed before the end of fiscal 2024. The Company has been proactively working with incumbents to clear the 900 MHz broadband allocation in the SDG&E service territory. Total payment of $50.0 million is comprised of an initial payment of $20.0 million and the remaining $30.0 million is due through fiscal 2024 as broadband spectrum is provided to SDG&E upon clearing of the 900 MHz incumbents by the Company and the granting of broadband licenses by the FCC.

As the Company is required to refund the initial payment in the event of termination or non-delivery of the 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.

Litigation

In addition to commitments and obligations in the ordinary course of business as reflected in the lease footnote above, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability.

The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of a material adverse outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.

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 March 31, 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 March 31, 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.
