Tennessee Code Title 45. Banks and Financial Institutions § 45-2-203

(b)(1) Prior to filing the notice of intent, the incorporators shall subscribe for shares of the corporation seeking to conduct banking business in Tennessee in an amount the commissioner deems adequate to pay the organizational expenses of the proposed bank.

(2) The expense fund shall be used for expenses incurred by the incorporators in connection with the organization of the proposed bank. Subscriptions paid by the incorporators for their shares in the proposed bank may be used to pay organizational expenses, but, in that case, shall not be commingled with funds in any account in which any non-incorporator funds have been or are to be deposited.
