Hey Bob (and everyone), just catching up after the holiday....been a long time...I had this (almost) happen to me last month...
After sifting through my daily ton o' emails back in October one day, I stopped and actually opened/read one from an account that holds this stock. Long story short they said they were going to remove the shares by a date in November unless I stated in writing that I wanted to keep them and also needed to pay a fee. After a ridiculous process they were not removed and I now have an annual fee to keep them.
I too felt it was odd that this stock, of all others I've had for much longer, was acted upon as it was.
Maybe its based on time held, and that is a BIG maybe, because I started purchasing shares in the another acct years after these and they are still there and I haven't received any correspondence in regards to them (Still sitting there, waiting, looking pretty).
I will likely reach out to them in attempt to proactively prevent this from happening without my knowing (neither account are with CW btw)...and would suggest others to do the same.
FWIW
