The method used shall be set forth in the bylaws. The credit committee shall hold such meetings as the business of the Federal credit union may require, not less frequently than once a month, to consider applications for loans or lines of credit. Reasonable notice of such meetings shall be given to all members of the committee. Except for those loans or lines of credit required to be approved by the board of directors in section
1757
(5) of this title, approval of an application shall be by majority of the committee who are present at the meeting at which it is considered provided that a majority of the full committee is present. The credit committee may appoint and delegate to loan officers the authority to approve applications.
