(1) All loan limits for member loans may, at the option of the board of directors, be established at the $1,000.00 amount nearest the amount computed in accordance with this Code section; and

(2) No member loan to the corporation shall be made if immediately thereafter the total amount of the obligations (whether under member loans or otherwise) of the corporation would exceed 50 times the amount then paid in on the capital of the corporation.

(c) The total amount outstanding on member loans to the corporation made by any member at any one time, when added to the amount of the investment in the capital of the corporation then held by such member, shall not exceed the lesser of:

(1) Twenty percent of the aggregate of the capital of the corporation then outstanding plus the total amount then outstanding on all member loans to the corporation, including in said total amount outstanding amounts validly called as member loans but not yet loaned;

(2) The following limit, to be determined each calendar year of membership on the basis of the audited balance sheet of such member at the close of its fiscal year immediately preceding or, in the case of an insurance company, its last annual statement to the Commissioner of Insurance:

(A) Five percent of the statutory capital base of a bank or trust company;

(B) One-half of 1 percent of the total outstanding loans made by savings and loan associations;

(C) Two and one-half percent of the capital and unassigned surplus of stock insurance companies, except fire insurance companies;

(D) Two and one-half percent of the unassigned surplus of mutual insurance companies, except fire insurance companies;

The adjusted loan limit of a member shall be the amount of such member's loan limit, as determined by reference to paragraph (2) of subsection (c) of this Code section, reduced by the balance of outstanding member loans made by such member to the corporation and the investment in capital of the corporation held by such member at the time of such call.

(e) All member loans to the corporation shall be evidenced by bonds, debentures, notes, or other evidences of indebtedness of the corporation, which shall be freely transferable at all times and which shall bear interest at a rate of interest determined by the board of directors.
