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.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; text-align: justify; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">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.

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 customers. In addition, the Company attempts to mitigate the credit risk related to specific IDT Global (formerly known as Carrier Services) 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 IDT Global customers with receivable balances that exceed the Company’s applicable payables in order to maximize the offset and reduce its credit risk.</span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: bold 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: center"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt">IDT CORPORATION</span></p> <p style="font: bold 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: center"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt; text-align: center"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"><b>NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)</b></span></p> <p style="font: 10pt Times New Roman, Times, Serif; margin-top: 0pt; margin-bottom: 0pt"><span style="font-family: Times New Roman, Times, Serif; font-size: 10pt"> </span></p>
