No association may establish or maintain a branch office or agency without the prior written approval of the director of the division of finance, except that temporary and incidental agencies may be created for individual transactions and for special temporary purposes without such approval. Each application for approval of the establishment and maintenance of a branch office or one or more agencies shall state the proposed location of the branch office or agency, the functions to be performed at the office or agency, the estimated volume of business at the branch office or agency, the estimated annual expense of the branch office or agency and the mode of payments for the branch office or agency and such additional matters as the director of the division of finance by regulation may require. Each such application shall be accompanied by a budget of the association for the current earnings period and for the next succeeding semiannual period, which reflects the estimated additional expense of the maintenance of each such branch office or agency. No branch application shall be granted if, in the opinion of the director or a majority of the members of the board on appeal, the policies, condition or operation of the applicant afford a basis for supervisory objection to the application. The director of the division of finance may hold a hearing at the director’s discretion on the application in accordance with such procedures as the director by regulation may require.
