strategic transactions, both domestic and international, that meet its return on investment and other criteria. In addition, the Company considers non-controlling investments in earlier stage businesses that it considers strategically relevant, and which may offer long-term growth potential for the Company, either individually, or as research and development businesses that can support the Company’s operating subsidiaries in new product and service development and offerings. The Company provides management, technical, financial, regulatory, and marketing services to its subsidiaries and typically receives a management fee equal to a percentage of their revenues which is eliminated in consolidation. For further information about the Company’s financial segments and geographical information about its operating revenues and assets, see Note 12 to the Consolidated Financial Statements included in this Report.</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-style:italic;font-weight:bold;letter-spacing:0.15pt;">COVID-19</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="font-style:italic;font-weight:bold;letter-spacing:0.15pt;visibility:hidden;"></span></p><p style="background-color:#ffffff;font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="letter-spacing:0.15pt;">In March 2020, the World Health Organization declared a novel strain of coronavirus, now referred to as COVID-19, as a pandemic, and the virus has now spread globally to over 200 countries and territories, including the United States and other countries in which the Company has substantial operations. The Company is continuing to monitor and assess the effects of the COVID-19 pandemic on its commercial operations, the safety of its employees and their families, its sales force and customers and any potential impact on the Company’s revenue in 2020. </span></p><p style="background-color:#ffffff;font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="letter-spacing:0.15pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="letter-spacing:0.15pt;">The preparation of the condensed consolidated financial statements requires the Company to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis the Company evaluates estimates, judgments and methodologies. The Company assessed certain accounting matters and estimates that generally require consideration of forecasted financial information in context with the information and estimates reasonably available to the Company and the unknown future impacts COVID-19 as of September 30, 2020 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s allowance for credit losses, the carrying value of the Company’s goodwill and other long-lived assets, financial assets, valuation allowances for tax assets and revenue recognition. The Company assessed the impacts of COVID-19 on the consolidated financial statements as of and for the quarter ended September 30, 2020, in particular the impacts on lines of revenues, operating expenses as well as the deferral and savings on other operating expenses and </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt;"><span style="letter-spacing:0.15pt;white-space:pre-wrap;">capital expenditures. </span><span style="white-space:pre-wrap;">During the three months ended September 30, 2020, while the Company’s International Telecom segment experienced strengthened demand for both its mobile and fixed services, its carrier services revenue declined as a result of a reduction in roaming revenue due to pandemic-related travel and stay-at-home restrictions as compared to the same period of 2019. Such restrictions also resulted in decreased mobile and carrier services revenues within its US Telecom segment during the three months ended September 30, 2020 as compared to the same period of 2019. However, in response to certain anticipated impacts, the Company was able to implement operating expense savings, particularly with respect to its International Telecom segment, that when coupled with Company-wide travel expense savings and capital expenditure deferrals, acted to offset much of the revenue loss or additional credit loss allowances caused by anticipated customer non-payment activity in the quarter.</span><span style="letter-spacing:0.15pt;white-space:pre-wrap;"> As a result, the Company’s assessment did not indicate that there was a material impact to the Company’s consolidated financial statements as of and for the quarter ended September 30, 2020. However, the Company’s future assessments of the impacts of COVID-19 for the remainder of the year and into 2021or its ability to realize continued operational expense savings, as well as other factors, could result in material impacts to the Company’s consolidated financial statements in future reporting periods. </span>For example, the local economies of many of the Company’s Caribbean markets are tourism-dependent and the decline in global travel activity resulting from COVID-19 may continue to impact its revenue and cash flows for certain services in these markets as the Company’s retail and enterprise customers may be unable to pay for services, and the Company’s international roaming revenue may decline as compared to last year. <span style="letter-spacing:0.15pt;">The extent to which the COVID-19 pandemic ultimately impacts the Company’s business, financial condition, results of operations, cash flows, and liquidity may differ from the Company management’s current estimates due to inherent uncertainties regarding the duration and further spread of the outbreak, its severity, actions taken to contain the virus or treat its impact, and how quickly and to what extent economic conditions normalize and more customary operating conditions resume. </span></p>
