Your right but they have released news since the last corporate action and will do so again if they have something to say :)My point being they are not being quiet :)
The last corporate action was the vote on the preferred shares and that may have reset the ticker change timeline and likely did.
A corporate action is any event that brings material change to a company and affects its stakeholders, including shareholders, both common and preferred, as well as bondholders. These events are generally approved by the company's board of directors; shareholders may be permitted to vote on some events as well.
