"DTC has been working proactively with the industry to increase awareness of our global lock process, to eliminate these difficulties in future. DTC also enhanced its procedures to expedite the release of any Important Notice reflecting a global lock, so firms can promptly halt trading in affected securities. Additionally, DTC implemented on June 10, 2011 a global lock reason [code] on its security master file and related outputs (ELIS and DWIZ files - see important notice B-0811-11 dated May 24, 2011 - http://www.dtcc.com/downloads/legal/imp_notices/2011/dtc/ope/0811-11.pdf) to allow Participants to receive an automated notification in the event a global lock occurs."
So my mistake, the Participant (the company and therefore Roth) are alerted as soon as the lock is placed and not beforehand. Did we immediately receive a PR? Nope, not even close.
