Intangible Assets [Abstract]
Intangible Assets	3. Intangible Assets Wireless licenses are considered indefinite-lived intangible assets. Indefinite-lived intangible assets are not subject to amortization but instead are tested for impairment annually, or more frequently if an event indicates that the asset might be impaired. There were no triggering events indicating impairment during the nine months ended December 31, 2021. During the nine months ended December 31, 2021, the Company acquired wireless licenses for cash consideration of $12.1 million, after receiving FCC approval, of which $10.1 million was spent on licenses acquired, including costs associated with license swaps, by entering into agreements with several third parties in multiple U.S. markets and $2.0 million was paid to the U.S. Treasury for Anti-Windfall payments, i.e. payments to secure the broadband channels to cover any shortfall of channels needed in a given county to reach the requisite 240 channels to be surrendered to secure a broadband license for such county, for 12 U.S. counties. As of December 31, 2021 and March 31, 2021, the Company recorded initial deposits to incumbents amounting to approximately $5.9 million and $2.3 million, respectively, that are refundable if the FCC does not approve the sale of the spectrum. Of the $5.9 million initial refundable deposit balance as of December 31, 2021, $5.5 million was included in prepaid expenses and other current assets and the remaining $0.4 million in other assets in the Consolidated Balance Sheets. Of the $2.3 million initial refundable deposit balance as of March 31, 2021, $1.9 million was included in prepaid expenses and other current assets and the remaining $0.4 million in other assets in the Consolidated Balance Sheets. As of December 31, 2021 and March 31, 2021, the Company recorded deferred charges of $0.8 million and $0.4 million, respectively, related to in-process deals, of which $0.1 million was recorded in prepaid expenses and other current assets and $0.7 million and $0.3 million, respectively, was recorded in other assets. During the nine months ended December 31, 2021, the Company applied for, and was granted by the FCC, broadband licenses for 12 counties. The Company recorded the new broadband licenses at their estimated accounting cost basis of approximately $13.6 million. In connection with receiving the broadband licenses, the Company disposed of $3.4 million related to the value ascribed to the narrowband licenses it relinquished to the FCC for the same 12 counties. The total carrying value of narrowband licenses included the cost to acquire the original narrowband licenses, Anti-Windfall payments paid to cover the shortfall in each county and the clearing costs.
