FACTORS

.01 The following tables present separately for each line of business the dis

count factors under § 846 for accident year 2000. All the discount factors presented in this section were determined using the applicable interest rate under § 846(c) for 2000, which is 6.09 percent, and by assuming all loss payments occur in the middle of the calendar year.

.02 If the groupings of individual lines of business on the annual statement change, taxpayers must discount the unpaid losses on the affected lines of business in accordance with the discounting patterns that would have applied to those unpaid losses based on their classification on the 1995 annual statement. See Rev. Proc. 98–11, 1998–1 C. B. 358, section 2, for additional background on discounting under section 846 and the use of the Secretary’s tables.

.03 Section V of Notice 88–100, 1988–2 C.B. 439, provides a composite discount factor to be used in determining the discounted unpaid losses for accident years that are not separately reported on the annual statement. Taxpayers that do not use the methodology set forth in section V of Notice 88–100 should instead use the discount factor for the appropriate year in the Secretary’s table for that line of business. If such taxpayers have unpaid losses relating to an accident year that is older than the last accident year for which a discount factor is presented in the Secretary’s table, those unpaid losses should be discounted using the discount factor for the last accident year in the Secretary’s table. See section 2.03(3) of Rev. Proc. 98–11. .04 Tables

and by assuming all estimated salvage is recovered in the middle of each calendar year. See Rev. Proc. 98–12, 1998–1 C.B. 367, for background regarding the tables. .02 These tables must be used by taxpayers irrespective of whether they elected to discount unpaid losses using their own historical experience under § 846.

.03 Section V of Notice 88–100, 1988–2 C. B. 439, provides guidance concerning the determination of discount factors for unpaid losses for accident years not separately reported on the annual statement. Taxpayers that do not use the methodology set forth in section V of Notice 88–100 should instead use the discount factors for the appropriate year in the Secretary’s table for that line of business. If such taxpayers have unpaid losses relating to an accident year that is older than the last accident year for which a discount factor is presented in the Secretary’s table, those unpaid losses should be discounted using the discount factor for the last accident year in the Secretary’s table. See section 2.03(3) of Rev. Proc. 98–11, 1998–1 C.B. 358. .04 Tables.
