With this support, the Company’s operating subsidiaries are able to improve their quality of service with greater economies of scale and expertise than would typically be available in the size markets they operate in. The Company provides management, technical, financial, regulatory, and marketing services to its operating subsidiaries and typically receives a management fee calculated as a percentage of their revenues, which is eliminated in consolidation. The Company also actively evaluates investment opportunities and other strategic transactions, both domestic and international, and generally looks for those that it believes fit the Company’s profile of telecommunications businesses and have the potential to complement the Company’s “First-to-Fiber” and “Glass & Steel™” approach in markets while keeping a focus on generating excess operating cash flows over extended periods of time. The Company uses the cash generated from its operations to maintain an appropriate ratio of debt and cash on hand and to re-invest in organic growth, to fund capital expenditures, to return cash to its stockholders through dividends or stock repurchases, and make strategic investments or acquisitions.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:26.45pt;margin:14pt 3.95pt 0pt 2pt;">As of December 31, 2023, the Company offered the following types of services to its customers:</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:36pt;margin:0pt;"><span style="font-size:8pt;visibility:hidden;"></span></p><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:0pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:46.45pt;"></td><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">●</td><td style="padding:0pt;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;font-weight:bold;">Mobile Telecommunications Services</span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">.

The most significant estimates relate to the allowance for credit losses on trade receivables, useful lives of the Company’s fixed and finite-lived intangible assets, allocation of purchase price to assets acquired and liabilities assumed in business combinations, fair value of indefinite-lived intangible assets, goodwill and income taxes. Actual results could differ significantly from those estimates.</p>
