Selmax & others,
I have just posted a comment on Cash Management Trusts under general thread. I know many CNP shareholders probably use cash management trusts outside big 4 banks, so perhaps a time to review situation i.e. carry minimum balances in these accounts. If a run on these types of accounts or accounts frozen, it would not be very pleasant i.e. no shopping money to spent you know where.
Please be cautious with CMT accounts.
Regards
Buffett
