(1) To derive Oregon taxable income of a financial institution which has changed from the reserve method of accounting to the specific charge-off method of accounting for federal tax purposes, there shall be subtracted from federal taxable income amounts which the financial institution recognized pursuant to section 585(c)(3) of the Internal Revenue Code.

(2) To derive Oregon taxable income, after the modification prescribed in subsection (1) of this section, the balance in the reserve for bad debts, as determined under ORS § 317.333 (2) (1985 Replacement Part), shall be taken into income using the same method as the financial institution used for federal tax purposes pursuant to section 585(c)(3) of the Internal Revenue Code.

(3) Subsections (1) and (2) of this section shall not apply to bad debt reserves for which an election under section 585(c)(4) of the Internal Revenue Code has been made. A financial institution which uses the method described in section 585(c)(4) of the Internal Revenue Code shall apply that same method to the balance in the reserve for bad debts, as determined under ORS § 317.333 (2) (1985 Replacement Part), and adjust its Oregon taxable income accordingly.
