Alabama Code Title 5. Banks and Financial Institutions § 5-5A-26

No bank shall accept, whether in a foreign or domestic transaction, for any one person, company, firm or corporation, to an amount equal at any time in the aggregate to more than 10 percent of its paid up and unimpaired capital and surplus, unless the bank is secured either by attached documents or by some other actual security growing out of the same transaction as the acceptance, and no bank shall accept such bills to an amount equal at any time in the aggregate to more than one half of its paid up and unimpaired capital stock and surplus. Banks which are members of the Federal Reserve System may accept such bills to an amount not exceeding at any time in the aggregate 100 percent of their paid up and unimpaired capital and surplus, but the aggregate of acceptances growing out of domestic transactions shall in no event exceed 50 percent of such capital and surplus.
