Let's not pay too much attention to what is showing at the brokers. They don't know anything about escrow CUSIP nor care. It's probably all done by a computer which probably tied to old records that show the preferred used to be tied to a trust or used to pay dividend. But it means nothing as all stocks including preferred were canceled.
Soon the escrow CUSIP will be gone from the brokers once all distributed shares are distributed which can happen by September 24 if no objection has been filed.
