The Company holds cash and cash equivalents at several major financial institutions, which often exceed FDIC insurance limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one financial institution and monitor the credit ratings of those institutions. While the Company may be exposed to credit losses due to the nonperformance of the holders of its deposits, the Company does not expect the settlement of these transactions to have a material effect on its results of operations, cash flows or financial condition.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px; FONT-SIZE: 1px">  </p> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers in various geographic regions and industry segments comprising the Company’s customer base. No single customer accounted for more than 10% of consolidated revenues in fiscal 2013, fiscal 2012 or fiscal 2011. However, the Company’s five largest customers collectively accounted for 10.0%, 8.1% and 7.1% of its consolidated revenues from continuing operations in fiscal 2013, fiscal 2012 and fiscal 2011, respectively. The Company’s customers with the five largest receivables balances collectively accounted for 16.6% and 24.3% of the consolidated gross trade accounts receivable at July 31, 2013 and 2012, respectively. This concentration of customers increases the Company’s risk associated with nonpayment by those customers. In an effort to reduce such risk, the Company performs ongoing credit evaluations of its significant retail telecom, wholesale termination and cable telephony customers. In addition, the Company attempts to mitigate the credit risk related to specific wholesale termination customers by also buying services from the customer, in order to create an opportunity to offset its payables and receivables and reduce its net trade receivable exposure risk. When it is practical to do so, the Company will increase its purchases from wholesale termination customers with receivable balances that exceed the Company’s applicable payables in order to maximize the offset and reduce its credit risk.</font></p> </div>
