VeriSign regularly reviews the adequacy of its accounts receivable allowance after considering the significance of the accounts receivable balance, each customer’s expected ability to pay and its collection history with each customer.

For those invoices not specifically reviewed, VeriSign maintains general reserve provisions based upon the age of the receivable.
