(a) A credit union may maintain specified books and records at a location in this state other than its principal place of business if it gives notice to the director of the location of the specified books and records and can produce those books and records at its principal place of business within 3 business days after a request from the commissioner to examine them.

(b) Except as required by other applicable law, a credit union may store records at an off-site facility or on alternative storage media if the records are available for examination by the director or his or her appointed agent.

(c) A domestic credit union may maintain records specific to a branch located outside of this state at that branch if the credit union can make the originals of those records available to the director within this state within 3 business days after a request from the director to examine them. If a law applicable in the state where the branch is located prohibits the removal of the original records from that state, the credit union shall notify the director of that law and provide copies of the records to the director.
