Threshold securities are equity securities that have an aggregate fail to deliver position for:

• Five consecutive settlement days at a registered clearing agency (e.g., National Securities Clearing Corporation (NSCC));
• totaling 10,000 shares or more; and
• equal to at least 0.5% of the issuer's total shares outstanding.

Threshold securities only include issuers registered or required to file reports with the Commission ("reporting companies").
