(2) Method of discounting The amount of the discounted unpaid losses as of the end of any taxable year attributable to any accident year shall be the present value of such losses (as of such time) determined by using— (A) the amount of the undiscounted unpaid losses as of such time, (B) the applicable interest rate, and (C) the applicable loss payment pattern.

(3) Limitation on amount of discounted losses In no event shall the amount of the discounted unpaid losses with respect to any line of business attributable to any accident year exceed the aggregate amount of unpaid losses with respect to such line of business for such accident year included on the annual statement filed by the taxpayer for the year ending with or within the taxable year.

(4) Determination of applicable factors In determining the amount of the discounted unpaid losses attributable to any accident year— (A) the applicable interest rate shall be the interest rate determined under subsection (c) for the calendar year with which such accident year ends, and (B) the applicable loss payment pattern shall be the loss payment pattern determined under subsection (d) which is in effect for the calendar year with which such accident year ends.

(2) Method of determination Determinations under paragraph (1) for any determination year shall be made by the Secretary— (A) by using the aggregate experience reported on the annual statements of insurance companies, (B) on the basis of the most recent published aggregate data from such annual statements relating to loss payment patterns available on the 1st day of the determination year, (C) as if all losses paid or treated as paid during any year are paid in the middle of such year, and (D) in accordance with the computational rules prescribed in paragraph (3).

(B) Treatment of certain losses (i) 3-year loss payment pattern In the case of any line of business not described in subparagraph (A)(ii), losses paid after the 1st year following the accident year shall be treated as paid equally in the 2nd and 3rd year following the accident year. (ii) 10-year loss payment pattern (I) In general The period taken into account under subparagraph (A)(ii) shall be extended to the extent required under subclause (II). (II) Computation of extension The amount of losses which would have been treated as paid in the 10th year after the accident year shall be treated as paid in such 10th year and each subsequent year in an amount equal to the amount of the average of the losses treated as paid in the 7th, 8th, and 9th years after the accident year (or, if lesser, the portion of the unpaid losses not theretofore taken into account).
