Commitments and Contingencies Disclosure [Abstract]
Contingencies and Guaranty	Contingencies and Guaranty Contingent Liability In February 2021, the Company entered into an agreement with SDG&E to sell 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”), 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. Delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses by county to SDG&E commenced 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. During the quarter ended September 30, 2022, the Company delivered to SDG&E 1.4 x 1.4 cleared Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. 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. A gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E in full. As the Company is required to refund payments it has received in the event of termination or non-delivery of the specific county’s 900 MHz Broadband Spectrum, it recorded the $20.2 million received from SDG&E as contingent liability in the Consolidated Balance Sheet. As of December 31, 2022, the Company recorded the $20.2 million payments from SDG&E as a short-term liability due to the expected timing of delivery. Xcel Energy Guaranty In connection with Xcel Energy Agreement, the Company entered into a guaranty agreement, under which the Company guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, the Company is required to refund payments it has received. In addition, to the extent it has performed its obligations, the Company’s liability and obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. The Company has not recorded a liability for these guarantees as delivery of the relevant cleared 900 MHz Broadband licenses or counties is expected to commence in the first quarter of Fiscal 2024 through 2028. As of December 31, 2022, the maximum potential liability of future undiscounted payments under this agreement is approximately $8.0 million. 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 and Macroeconomic Conditions 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 world. The ultimate extent of the impact of COVID-19 on the future financial performance of the Company will depend on ongoing developments, all of which remain uncertain and cannot be predicted. The Company continues to closely monitor the risks posed by COVID-19 and adjusts its practices accordingly. Additionally, although difficult to quantify, the Company believes that the current macroeconomic environment, including inflation, may have an adverse effect on the Company’s target customers’ businesses, which may harm the Company’s commercialization efforts and negatively impact the Company’s revenues. If the Company is not able to control its higher operating costs or if the Company’s commercialization efforts are slowed or negatively impacted, continued periods of high inflation could have a material adverse effect on the Company’s business, operating results and financial condition. In December 2020, the Company deferred payroll taxes under the Coronavirus Aid Relief and Economic Security Act, which was signed into law on March 27, 2020. The deferral amounted to approximately $0.3 million, which has assisted the Company in managing the financial impact caused by the pandemic. Of the total deferred, approximately $0.2 million was remitted to the IRS during Fiscal 2022, with the remaining amount remitted during the three months ended December 31, 2022.
