authorities and have been cooperating in their investigation. While to date we have not discovered conclusive evidence that a theft occurred, we identified some store practices that may
have made information systems at our stores vulnerable during periods before August 2004. Notably, without our knowledge, the card processing software we used inadvertently retained credit and
debit card "Track 2" data, consisting of, among other items, the customer's name, card number, card expiration date and card verification number. In addition, the internet gateways on our computers in
some stores may not have been fully secure at all times. As a result, outside parties may have gained access to stored information. We began accepting credit cards in 1999, and it is possible that all
of the cards we processed since then may have been vulnerable. In the three months prior to being notified of the problem, we processed between 1.3 million and 1.5 million credit and
debit card charges each month.
To date, we have received claims through the acquiring bank with respect to fewer than 2,000 purportedly fraudulent credit and debit card charges allegedly arising out of this matter in
an aggregate amount of about $1.2 million. We've also incurred $0.9 million of expense in connection with fines imposed by the Visa and MasterCard card associations on the acquiring
bank. In 2004, we recorded charges of $4.0 million to establish a reserve for claims seeking reimbursement for purportedly fraudulent credit and debit card charges, the cost of replacing cards,
monitoring expenses and fees, and fines imposed by Visa and MasterCard. All of the reimbursement claims are being disputed, although we've not formally protested all of the charges. At
October 31, 2005, after charging these expenses against the reserve, the remaining reserve was $1.9 million. In addition to the reserve, we've also incurred about $1.5 million of
additional expenses in this matter, including $1.3 million for legal fees, bringing our total expense relating to this matter to $5.5 million. We have not reserved any additional amounts
to date in 2005.
may in the future become subject to additional claims for purportedly fraudulent transactions arising out of this matter. As long as a credit or debit card is active, fraudulent
charges may be made using that card until the card's expiration date. We may also be subject to lawsuits or other proceedings by various interested parties, including banks and credit unions that
issue cards, cardholders (either individually or as part of a class action lawsuit) and federal and state regulators. The statutes of limitation for pursuing some of these potential claims may extend
for six years or more in some cases, depending on the circumstances. Moreover, the application of the law and the rules and procedures of the major card associations in these circumstances is
generally untested. Any lawsuit or other proceeding will likely be complex, costly and protracted, which could in turn divert financial and management resources from execution of our business plan. We
have no way to predict the level of claims or the number or nature of proceedings that may be asserted against us, nor can we quantify the costs that we may incur in connection with investigating,
responding to and defending any of them. If we litigate these matters, we may not be able to defend against penalties successfully. The ultimate outcome of this matter could differ materially from the
amounts we've recorded in our reserve and could have a material adverse effect on our financial results and condition. Consumer perception of our brand could also be negatively affected by these
events, which could further adversely affect our results and prospects.
Despite the changes we've made to our information systems as a result of this matter, we still need to periodically upgrade our software. We rely on commercially available software and
other technologies to provide security for processing and transmission of customer credit card data. About 44% of our current sales are attributable to credit card transactions, and we expect credit
card usage to increase. Our systems could be compromised in the future, which could result in the misappropriation of customer information or the disruption of our systems. Either of those
consequences could have a material adverse effect on our reputation and business or subject us to additional liabilities.
Failure to receive frequent deliveries of higher-quality food ingredients and other supplies could harm our operations.
Our ability to maintain our menu depends in part on our ability to acquire ingredients that meet our specifications from reliable suppliers. Shortages or
interruptions in the supply of ingredients caused by unanticipated demand, problems in production or distribution, food contamination, inclement weather or
