Nonetheless, we face a number of challenges and uncertainties in operating our business, including: • our ability to maintain the health, capacity, control and level of service of our satellites; • our ability to develop and launch new and innovative products and services; • changes in general economic, business and industry conditions, including the effects of currency exchange rates; • our reliance on a single primary commercial gateway and a primary satellite network operations center; • competition from other mobile satellite service providers and, to a lesser extent, from the expansion of terrestrial-based cellular phone systems and related pricing pressures; • market acceptance of our products; • regulatory requirements in existing and new geographic markets; • challenges associated with global operations, including as a result of conflicts in or affecting markets in which we operate; • rapid and significant technological changes in the telecommunications industry; • our ability to generate sufficient internal cash flows to repay our debt; • reliance on our wholesale distribution network to market and sell our products, services and applications effectively; • reliance on a global supply chain, including single-source suppliers for the manufacture of most of our subscriber equipment and for some of the components required in the manufacture of our end-user subscriber equipment and our ability to purchase component parts that are periodically subject to shortages resulting from surges in demand, natural disasters or other events, including the COVID-19 pandemic; and • reliance on a few significant customers, particularly agencies of the U.S. government, for a substantial portion of our revenue, as a result of which the loss or decline in business with any of these customers may negatively impact our revenue and collectability of related accounts receivable.

We designated the Cap as a cash flow hedge of the variability of the LIBOR-based interest payments (now SOFR-based interest payments) on the Term Loan. The effective portion of the Cap’s change in fair value is recorded in accumulated other comprehensive income (loss) and reclassified into earnings during the period in which the hedged transaction affects earnings.
