Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 3 — Fair Value Measurements In accordance with the authoritative guidance for financial assets and liabilities measured at fair value on a recurring basis (ASC 820), the Company determines fair value based on the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants, and prioritizes the inputs used to measure fair value from market-based assumptions to entity specific assumptions: • Level 1 — Inputs based on quoted market prices for identical assets or liabilities in active markets at the measurement date. • Level 2 — Observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Inputs which reflect management’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. The inputs are unobservable in the market and significant to the instrument’s valuation. The Company had $5.1 million and $5.0 million in cash equivalents (Level 1) and no liabilities measured at fair value on a recurring basis as of December 31, 2022 and March 31, 2022, respectively. The following section describes the valuation methodologies the Company uses to measure financial instruments at fair value: Cash equivalents — The Company’s cash equivalents consist of money market funds. Money market funds are valued using quoted prices for identical assets in an active market with sufficient volume and frequency of transactions (Level 1). Contingencies — In connection with the acquisition of the remaining 51% interest in EBI on April 30, 2021 (see Note 5 — Acquisitions for more information), part of the purchase price consideration will not be determined until two years after the closing date, when the Company may pay or receive up to €20.0 million, or approximately $21.2 million, in cash. The consideration to be paid in the future is contingent based on certain outcomes as defined in the acquisition agreement. Each reporting period, the Company estimates the fair value of the contingent consideration based on unobservable inputs and probability weightings using standard valuation techniques (Level 3). The fair value amount is currently recorded in other current assets on the condensed consolidated balance sheets and any change to fair value is recorded in the Company’s condensed consolidated statements of operations each reporting period. As of December 31, 2022 and March 31, 2022, and for the three-month and nine-month periods ended December 31, 2022 and 2021, the Company’s fair value estimate, and change in fair value of the contingent consideration were immaterial. Long-term debt — The Company’s long-term debt consists of borrowings under its Term Loan Facility, Revolving Credit Facility and Ex-Im Credit Facility (collectively, the Credit Facilities), $700.0 million in aggregate principal amount of 2025 Notes, $600.0 million in aggregate principal amount of 2027 Notes, $400.0 million in aggregate principal amount of 2028 Notes and finance lease obligations reported at the present value of future minimum lease payments with current accrued interest. Long-term debt related to the Revolving Credit Facility is reported at the outstanding principal amount of borrowings, while long-term debt related to the Term Loan Facility, the Ex-Im Credit Facility, the 2025 Notes, the 2027 Notes and the 2028 Notes is reported at amortized cost. However, for disclosure purposes, the Company is required to measure the fair value of outstanding debt on a recurring basis. The fair value of the Company’s long-term debt related to the Term Loan Facility and the Revolving Credit Facility approximates its carrying amount due to its variable interest rate, which approximates a market interest rate. As of December 31, 2022 and March 31, 2022, the fair value of the Company’s long-term debt related to the Ex-Im Credit Facility was determined based on a discounted cash flow analysis using observable market interest rates for instruments with similar terms (Level 2) and was approximately $56.7 million and $78.0 million, respectively. As of December 31, 2022 and March 31, 2022, the estimated fair value of the Company’s outstanding long-term debt related to each series of Notes was determined based on actual or estimated bids and offers for such series of Notes in an over-the-counter market (Level 2) and was $652.8 million and $682.5 million, respectively, for the 2025 Notes, $550.5 million and $588.8 million, respectively, for the 2027 Notes, and $305.0 million and $382.7 million, respectively, for the 2028 Notes. Satellite performance incentive obligations — The Company’s contracts with satellite manufacturers require the Company to make monthly in-orbit satellite performance incentive payments with respect to certain satellites in service, including interest, through fiscal year 2028, subject to the continued satisfactory performance of the applicable satellites. The Company records the net present value of these expected future payments as a liability and as a component of the cost of the satellites. However, for disclosure purposes, the Company is required to measure the fair value of outstanding satellite performance incentive obligations on a recurring basis. The fair value of the Company’s outstanding satellite performance incentive obligations is estimated to approximate their carrying value based on current rates (Level 2). As of December 31, 2022 and March 31, 2022, the Company’s estimated satellite performance incentive obligations relating to certain satellites in service, including accrued interest, were $21.3 million and $23.7 million, respectively.
