(a) Securities, other than those referred to in § 56-3-113, held by an insurer shall be valued, in the discretion of the department, at their market value, at their appraised value, or at prices determined by it as representing their fair market value. Nothing in this section applies to loans secured by mortgages upon improved real property or upon leasehold estates in improved real property, which shall continue to be valued on the basis of amortization to maturity.

(b) Preferred or guaranteed stocks or shares, while paying full dividends, may be carried at a fixed value in lieu of market value, at the discretion of the department and in accordance with the method of valuation it approves.

(c) Stock of a subsidiary corporation of an insurer shall not be valued at an amount in excess of the net value of the stock as based upon those assets only of the subsidiary that would be eligible under this chapter for investment of the funds of the insurer directly.

(d) No valuations under this section shall be inconsistent with any applicable valuation or method then currently formulated or approved by the National Association of Insurance Commissioners or its successor organization.

(e) Before the commissioner takes any action pursuant to this section, the commissioner shall give written notice to the insurer involved, stating specifically the nature of the alleged violation, and fixing a time and place, at least ten (10) days thereafter, when a hearing on the matter shall be held. The burden of proof shall be on the commissioner to show the lack of statutory criteria by the preponderance of the evidence. After the hearing, or upon failure of the accused to appear at the hearing, the commissioner, if the commissioner finds a violation, may enter an appropriate order under this section as the commissioner deems advisable.

(f) When the commissioner takes action in any or all of the ways set out in this section, the party aggrieved may appeal from the action to the chancery court of Davidson County.
