Introduction

SEC. 4. APPLICATION

Internal Revenue Bulletin 2005-49 · 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 2005 accident year. All the discount factors presented in this section were determined using the applicable interest rate under § 846(c) for 2005, which is 4.44 percent, and by assuming all estimated salvage is recovered in the middle of each calendar year. See

Rev. Proc. 2003–18, 2003–1 C.B. 439, 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 a composite discount factor to be used in determining the discounted unpaid losses for accident years that are not separately reported on the NAIC Annual Statement. The tables separately provide discount factors for taxpayers who elect to use the composite method. Rev. Proc. 2002–74, 2002–2 C.B. 980, clarifies that for certain insurance companies subject to tax under § 831 the composite method for discounting unpaid losses set forth in Notice 88–100, section V, 1988–2 C.B. 439, is permitted but not required. This revenue procedure further provides alternative methods for computing discounted unpaid losses that are permitted for insurance companies not using the composite method, and sets forth a procedure for insurance companies to obtain automatic consent of the Commissioner to change to one of the methods described in Rev. Proc. 2002–74.
