If a banking or financial organization has sent a statement or other business communication concerning such property to the owner by first-class mail and the statement or other business communication has not been returned for inability to make delivery to the addressee, the property shall not be presumed to be abandoned. The five-year abandonment period shall begin to run when any statement or other business communication to the owner has been returned as undeliverable, or on the last date that the owner has communicated with the banking or financial organization in any of the ways specified in paragraphs 1 through 5 of this subsection, whichever is the later.
Upon presumed abandonment of the automatically renewable time deposit, the holder shall report the presumed abandonment to the State Treasurer and may, at the holder's option, either retain the property or pay or deliver it to the State Treasurer.
