The Company places its cash equivalents in instruments that meet high-quality credit standards as specified in the Company’s investment policy guidelines. Accounts receivable are due from customers located in major metropolitan areas in the United States, Europe, Canada, Mexico, Asia, South America, Australia and Africa. Receivables from the Company’s net-centric (wholesale) customers are generally subject to a higher degree of credit risk than the Company’s corporate customers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:18pt;margin:0pt 0pt 12pt 0pt;">The Company relies upon an equipment vendor for the majority of its network equipment and is also dependent upon many third-party fiber providers for providing its services to its customers.</p>
