Idaho Code § 26-2180
The Idaho corporate credit union may loan to members upon such security and for purposes only as provided in its bylaws. Loans shall be evidenced by a written instrument and within limits set by board policy. No loan shall be made unless approved in writing by a majority of the board of directors or manager as delegated by the board of directors.
The board may establish lines of credit to member credit unions based on the financial statements of the member credit union. Where a line of credit has been approved, application for loans need no further consideration as long as the aggregate obligation does not exceed the limits of such line of credit. The board of directors shall at least once a year review all lines of credit and any lines of credit shall expire if the member becomes more than sixty (60) days delinquent in its obligations to the Idaho corporate credit union.
