(2) The Oregon taxable income of an insurer shall be computed by adding or subtracting, to the insurer’s net gain from operations as determined under subsection (1) of this section, such of the following items as apply to the insurer:

(a) Add the amount of federal and state income taxes deducted by the insurer in computing its net gain from operations.

(b) Add penalty interest received by the insurer arising out of prepayment of loans made by the insurer.

(c) Add realized gains and losses on sales or exchanges by the insurer of property.

(d) Subtract, if the insurer so elects, additional or accelerated depreciation on real and personal property that is in excess of the depreciation deducted by the method used in computing the insurer’s net gain from operations.

(e) Subtract that amortized portion of the contribution for past service credits made to qualified plans and exempt trusts for employees allowed as a deduction.

(f) Add or subtract, as appropriate, increases or decreases in mandatory reserves that the insurer is required to maintain by law or by rules or directives of the Director of the Department of Consumer and Business Services or the insurance director or commissioner of the state of domicile of the foreign or alien insurer, other than increases or decreases that (A) are deducted in arriving at the insurer’s net gain from operations, or (B) result from net gains or losses, realized or unrealized, in the value of the insurer’s property and investments.

(g) Add or subtract, as appropriate, increases or decreases in reserves for policies and obligations outstanding before the beginning of the taxable year resulting from changes in the bases and methods of computing such reserves that are justified by accounting and actuarial practices applicable to or accepted by the insurance industry, commonly known as "reserve strengthening" or "reserve weakening."

(3) Income, expenses, gains, losses, exclusions, deductions, assets, reserves, liabilities and other items properly attributable to one or more separate accounts authorized under ORS 733.220 shall not be taken into account in determining taxable income of an insurer under ORS 317.010 (11), 317.122 and 317.650 to 317.665 until such amounts or items are returned to and reflected on the general accounts of such insurer so as to be available generally to or for the benefit of contract and policyholders of the insurer.
