(A) The total liabilities, direct and indirect, of any one borrower to a bank, including in the liabilities of a company or firm the liabilities of its several members, may never exceed ten percent of the bank’s unimpaired capital, except by two-thirds vote of the directors of the bank, in which case liabilities other than those of officers and directors as described in § 34-13-80 may be extended to fifteen percent of the bank’s unimpaired capital. However, liabilities may be extended by an additional amount not to exceed thirty-five percent of the unimpaired capital of the bank when the additional loans are secured by direct obligations of the United States Government or direct obligations of this State. The discount of bills of exchange drawn in good faith against existing values and the discount of commercial or business paper are not considered money borrowed.

(3) surplus;

(4) undivided profits, excluding disallowed intangibles;

(5) reserve for contingencies and other capital reserves, excluding accrued dividends on perpetual and limited life preferred stock;

(6) mandatory convertible debt;

(7) allowance for loan losses; and

(8) capital debentures or notes, convertible or otherwise, having an average original maturity of at least seven years and having been designated specifically as part of the bank’s unimpaired capital by resolution duly adopted by the board of directors of the bank.

(C) For purposes of this section, "total liabilities" include any credit exposure of a bank to a borrower arising from a derivative transaction, repurchase agreement, reverse repurchase agreement, securities lending transaction, or securities borrowing transaction between a bank and that borrower.

(D) For purposes of this section, "derivative transaction" means any transaction that is a contract, agreement, swap, warrant, note, or option that is based, in whole or in part, on the value of any interest in, or any quantitative measure or the occurrence of any event relating to one or more commodities, securities, currencies, interest, or other rates, indices, or assets.
