The Securities Information Center, or SIC, is in charge of keeping reports for all lost and stolen securities. SEC Rule 17f-1 outlines the requirements for reporting an inquiry with respect to missing, lost, counterfeit, or stolen securities. When it is believed criminal activity was involved, the theft must be reported within one business day of discovery to the SIC, the registered transfer agent for the issue, and the Federal Bureau of Investi_gations (FBI). When criminal activity is not believed to be involved and securities have been missing or lost for at least two business days, a report must be made within one business day by the end of this period to the SIC and the registered transfer agent for the issue. When securities are found to be counterfeit, a report must be made within one business day of discovery to the SIC, the registered transfer agent for the issue, and the FBI. If securities are discovered to be missing after an internal audit or count, and no criminal activity is suspected, a report must be filed with the SIC within ten business days of discovery or as soon as the securities can be identified by certificate number. When stolen, missing, lost, or counterfeit securities have been recovered, the appropriate authority must be notified within one business day of the recovery.
