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. PRRM's not on the SHO list, and IMHO there is no shorting happening that would have any effect on the PPS.
