Regulation of Bank The Pennsylvania Department of Banking and Securities, which has primary supervisory authority over banks chartered in Pennsylvania, regularly examines banks in such areas as reserves, loans, investments, management practices, and other aspects of operations. The FDIC is the primary federal regulator of state-chartered banks and also regularly examines state-chartered banks for safety and soundness. These examinations are designed for the protection of the subsidiary bank’s depositors rather than ACNB Corporation’s stockholders.
