(a) The taxpayer's net worth shall be determined for purposes of the taxes levied by this chapter in accordance with the accounting principles used in preparing the taxpayer's financial statements reported to its owners. If the taxpayer's financial statements are not prepared in accordance with generally accepted accounting principles, then net worth for such purposes shall be determined either on the same basis as it prepares its federal income tax return or as required by the appropriate regulatory agencies having jurisdiction. However, in the case of a taxpayer that is an insurer holding a certificate of authority to conduct an insurance business within the State of Alabama, net worth for such purposes shall be computed on the same basis as its financial statements are prepared in accordance with the requirements of the State of Alabama Insurance Department.
(b) Net worth may be determined from the taxpayer's financial statements for its determination period if those financial statements reasonably reflect the financial condition of the taxpayer as of the January 1 following the determination period.
