TJX has a reserve for its estimate of the remaining probable losses arising from an unauthorized intrusion or intrusions (the intrusion or intrusions, collectively, the “Computer Intrusion”) into portions of its computer system, which was discovered late in fiscal 2007 and in which TJX believes customer data were stolen. The reserve balance was $17.2 million at April 30, 2011. As an estimate, the reserve is subject to uncertainty, actual costs may vary from the current estimate however such variations are not expected to be material.
