BB&T is shutting down six bank branches as part of its $1.8bn takeover of National Penn Bancshares.

The branches to be closed include two each in Berks and Chester counties, and single branches in Lancaster and Montgomery counties.

BB&T has not yet disclosed the exact date of the closure, but said that the move will be effective following the finalisation of the acquisition deal in mid-2016.

The closure will likely impact National Penn’s back-office staff, while all of its high-performing, direct client-facing associates and revenue producers will be retained.

BB&T earlier announced the closure of an overall 25 branches as part of the acquisition to phase out overlapping service areas.

The names of the other locations to be closed will be revealed at a later date, BB&T spokesman David White said.
