SECTION 4. APPLICATION
Internal Revenue Bulletin 2001-53 · 2026-10-03 edition · updated 2026-10-04 · United States
.01 The following tables present separately for each line of business the discount factors under § 832 for the 2001 accident year. All the discount factors presented in this section were determined using the applicable interest rate under § 846(c) for 2001, which is 6.00 percent, 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).
