Prior to approving the acquisition by any Delaware bank holding company of any bank located in another state or bank holding company, the Commissioner may enter into cooperative agreements with the appropriate regulatory authorities for the periodic examinations of any out-of-state bank holding company or bank acquired by a Delaware bank holding company and may accept reports of examination and other records from such authorities in lieu of conducting his own examination. The Commissioner may enter into joint actions with other regulatory authorities having concurrent jurisdiction over any out-of-state bank holding company or bank acquired by a Delaware bank holding company or may take such actions independently to carry out his responsibilities under this subchapter to assure the safety and soundness of any Delaware bank and to assure compliance with applicable Delaware banking laws.
