The term “investment income” means the gross amount of income earned during the taxable year from interest, dividends, and rents, computed as follows: To all interest, dividends, and rents received during the taxable year, add interest, dividends, and rents due and accrued at the end of the taxable year, and deduct all interest, dividends, and rents due and accrued at the end of the preceding taxable year.

In the case of any 100 percent dividend paid to an insurance company to which this part applies by any insurance company, the amount of the decrease in the deductions of the payee company by reason of the portion of such dividend attributable to prorated amounts shall be reduced (but not below zero) by the amount of the decrease in the deductions (or increase in income) of the payor company attributable to the application of this section or section 805(a)(4)(A) to such amounts.
The term “expenses incurred” means all expenses shown on the annual statement approved by the National Association of Insurance Commissioners, and shall be computed as follows: To all expenses paid during the taxable year, add expenses unpaid at the end of the taxable year and deduct expenses unpaid at the end of the preceding taxable year. For purposes of this subchapter, the term “expenses unpaid” shall not include any unpaid loss adjustment expenses shown on the annual statement, but such unpaid loss adjustment expenses shall be included in unpaid losses. For the purpose of computing the taxable income subject to the tax imposed by section 831, there shall be deducted from expenses incurred (as defined in this paragraph) all expenses incurred which are not allowed as deductions by subsection (c).
Subparagraph (B) of paragraph (4) shall be applied with respect to insurance contracts described in section 816(b)(1)(B) by substituting “100 percent” for “80 percent” each place it appears in such subparagraph (B), and subparagraph (C) of paragraph (4) shall be applied by not taking such contracts into account.
Except as provided in section 381(c)(22) (relating to carryovers in certain corporate readjustments), if, for any taxable year beginning before January 1, 1993, the taxpayer ceases to be an insurance company taxable under section 831(a), the aggregate adjustments which would be made under paragraph (4)(C) for such taxable year and subsequent taxable years but for such cessation shall be made for the taxable year preceding such cessation year.
Nothing in this section shall permit the same item to be deducted more than once.
The deduction under paragraph (1) shall be allowed only to the extent that tax and loss bonds are purchased in an amount equal to the tax benefit attributable to such deduction, as determined under regulations prescribed by the Secretary, on or before the date that any taxes (determined without regard to this subsection) due for the taxable year for which the deduction is allowed are due to be paid. If a deduction would be allowed but for the fact that tax and loss bonds were not timely purchased, such deduction shall be allowed to the extent such purchases are made within a reasonable time, as determined by the Secretary, if all interest and penalties, computed as if this sentence did not apply, are paid.
Each company which writes mortgage guaranty insurance shall, for purposes of this part, establish and maintain a mortgage guaranty account.
The provisions of this subsection shall also apply in all respects to a company which writes lease guaranty insurance or insurance on obligations the interest on which is excludable from gross income under section 103. In applying this subsection to such a company, any reference to mortgage guaranty insurance contained in this section shall be deemed to be a reference also to lease guaranty insurance and to insurance on obligations the interest on which is excludable from gross income under section 103; and in the case of insurance on obligations the interest on which is excludable from gross income under section 103, the references in paragraph (1) to “losses resulting from adverse economic cycles” include losses from declining revenues related to such obligations (as well as losses resulting from adverse economic cycles), and the time specified in subparagraph (A) of paragraph (5) shall be the twentieth preceding taxable year.
