Subsequent event	25. SUBSEQUENT EVENT SXM-7 satellite On January 27, 2021, Sirius XM Holdings Inc. (“Sirius XM”) announced in its public filings with the U.S. Securities and Exchange Commission that there is an evaluation underway to determine the extent of damage to its SXM-7 satellite caused by certain events on January 16, 2021. The SXM-7 satellite was constructed by the Company and launched by Sirius XM on December 13, 2020. As of December 31, 2020, the satellite was functioning as intended. As of February 11, 2021, although there can be no assurance of full recovery of the operations of the SXM-7 satellite, the Company was continuing the process of troubleshooting and diagnosing the situation. However, on that date, Sirius XM asserted to the Company that the SXM-7 satellite is a “total loss”. As previously disclosed, the Company’s contractual arrangements with Sirius XM for the construction of the SXM-7 satellite include industry-standard provisions regarding, among other things, transfer of risk of loss upon launch. As of December 31, 2020, the Company had $15 million in unbilled receivables that are collectible from Sirius XM upon in-orbit acceptance of the SXM-7 satellite (the “Acceptance Receivables”) and $14 million in orbital receivables that are collectible over the satellite’s expected in-orbit life of 15 years (the “Orbital Receivables” and, collectively with the Acceptance Receivables, the “Receivables”), for which the entire amount of the Receivables were considered collectible. If the SXM-7 satellite is validly declared a “total loss” pursuant to the Company’s contractual arrangements, the collectability of the entire $29 million of Receivables would be at risk. In addition to the risk associated with the outstanding receivables, the Company may be exposed to liquidated damages not previously accrued at December 31, 2020 of up to $9 million.
