Authority of international bank, interstate state bank, or interstate national bank to branch.

(a) An international bank, an interstate state bank, or an interstate national bank whose deposits are insured by the Federal Deposit Insurance Corporation may acquire a branch bank as the result of a merger or consolidation of the international bank, interstate state bank, or interstate national bank with, or the purchase of all or substantially all of the assets of, a state bank, a national bank with its principal office in this state, or a branch of the state bank or national bank, unless the state bank or national bank is a recently formed bank. (b) An international bank may establish a new branch bank in this state or acquire a recently formed bank if the department approves the establishment or acquisition before the establishment or acquisition occurs. An interstate state bank or interstate national bank may not establish a branch bank in this state unless the establishment occurs through an acquisition under (a) of this section of a bank located in the state. An interstate state bank or interstate national bank may not establish a new branch bank in this state. (c) An interstate state bank, interstate national bank, or international bank that opens, occupies, or maintains a branch bank in the state has the same powers under the laws of the state as a state or national bank of the same type.
