Upon application of the bank, the commissioner may, in extraordinary circumstances, adjust or waive the percentage a bank shall write off the real property each year, may extend the period in which the real property may be held beyond ten (10) years, or any combination of the foregoing. If the commissioner reduces, waives, or adjusts the amount of write-off, the real property may not be carried at more than the appraised value of the property; (C) Real property which has been written off but not disposed of shall be maintained on the bank's books at some nominal value; (D) If the bank's board of directors deems the real property owned to be a prudent investment for income or appreciation for the bank, the board may take action to maintain the real property on the bank's books as an investment, pursuant to subdivision (a)(9); (E) Not more than one hundred twenty (120) days before or thirty (30) days after the date the parcel is acquired by the bank as real property owned, or from the date on which the bank legally acquires the real property for investment purposes, the bank shall obtain from an independent, qualified appraiser an appraisal of the parcel; provided, however, that: (i) For parcels whose book value is five hundred thousand dollars ($500,000) or less, the bank may obtain an evaluation in lieu of an appraisal; and (ii) For parcels whose book value is two hundred fifty thousand dollars ($250,000) or less, no appraisal or evaluation shall be required; and (F) Within twelve (12) months from the date the bank acquires the real property, and every twelve (12) months thereafter for as long as the bank owns the real property, the bank shall obtain another appraisal or evaluation, whichever is appropriate as provided for in subdivision (b)(2)(E). (c) As used in this section, "investment" means the purchase of any interest in any property of any nature principally for the purpose of deriving profit from changes in the value of the property or from dividends, interest or rent thereon, as distinguished from the purpose of using the property in the conduct of the business of a bank. Notwithstanding the foregoing, the investment by a bank or trust company in one (1) or more subsidiaries, or the underwriting of or dealing in certificates of deposit, bankers' acceptances or those securities that are permissible investments for a bank under subdivisions (a)(1)-(14), shall not constitute an investment within the meaning of this section. (d) (1) In addition to the other provisions of this section, upon thirty (30) days' prior written notice to the commissioner, providing such detail as the commissioner may require, a bank may invest, in the aggregate, up to seventy-five percent (75%) of its unimpaired capital, surplus and undivided profits in the stock or purchase the assets of other corporations, firms, partnerships or companies, including limited liability corporations and limited liability partnerships, which are or will be: (A) Primarily engaging in activities permissible for federally chartered financial institutions, their authorized subsidiaries or bank holding companies under applicable laws, rules, regulations or orders; (B) Primarily engaging in activities of a financial nature, including, but not limited to, the transmission or processing of information, data or payments relating to the activities, all forms of securities activities not otherwise authorized, together with other activities that the commissioner shall determine and that may be permissible for other bank and non-bank financial institutions chartered by Tennessee or other states by regulation or order; or (C) Engaging in any other activities approved by the commissioner. (2) Unless denied by the commissioner within thirty (30) days following receipt of the written notice or upon approval prior to the expiration of the thirty (30) days, a bank may complete its investment in the stock or purchase the assets of the other corporation, firm, partnership or company, or commence a new activity through an existing subsidiary. The commissioner may extend the thirty-day period for approval or denial, for an additional thirty-day period, by notifying the applicant if the commissioner determines that the proposed investment or activity raises issues that require additional information or additional time for analysis. (3) The commissioner shall monitor the impact of activities and investments of banks approved under this section on the safety and soundness of the banks. Any stocks owned or hereafter acquired in excess of the limitations herein imposed shall be disposed of at public or private sale within six (6) months after the date of acquiring the stocks, and if not so disposed of, they shall be charged to profit and loss account, and no longer carried on the books as an asset. The limit of time in which the stocks shall be disposed of or charged off the books of the bank may be extended by the commissioner if, in the commissioner's judgment, it is for the best interest of the bank that the extension be granted. (4) The commissioner may, as a condition of approving an investment under this section, impose limits on the loans that each bank can make to the corporation, firm or partnership. (5) The commissioner shall maintain a public file, available for inspection at the department's offices, which shall contain a summary or synopsis of any application submitted under this subsection (d). The summary shall include only the name of the institution applying, the proposed activity and the decision of the commissioner. (6) Any state or national bank or subsidiary that engages in an activity that subjects it to licensure and/or regulation under other than title 45, chapter 2, shall be subject to licensure and/or regulation on a basis that does not discriminate by the appropriate regulatory agency that licenses and/or regulates non-banks that engage in the same activity.
