(a) A corporation may establish the fair market value of total gross assets for the purpose of the limitations under Section 6-5-682 through any method reasonable under the circumstances, including either of the following:
(1) By reference to the going concern value of the assets or to the purchase price attributable to or paid for the assets in an arm's length transaction.
(2) In the absence of other readily available information from which fair market value can be determined, by reference to the value of the assets recorded on a balance sheet.
(b) Total gross assets include intangible assets.
(c) Total gross assets include the aggregate coverage under any applicable liability insurance that was issued to the transferor whose assets are being valued for purposes of this section, which insurance has been collected or is collectible to cover successor asbestos-related liabilities except compensation for liabilities arising from workers' exposure to asbestos solely during the course of their employment by the transferor. A settlement of a dispute concerning the insurance coverage entered into by a transferor or successor with the insurers of the transferor before September 1, 2011, shall be determinative of the aggregate coverage of the liability insurance to be included in the calculation of the transferor's total gross assets.
