SECTION 4. TABLES OF DISCOUNT
Internal Revenue Bulletin 2013-49 · 2026-10-03 edition · updated 2026-10-04 · United States
FACTORS
.01 The following tables present separately for each line of business the discount factors under § 832 for the 2013
accident year. All the discount factors presented in this section were determined using the applicable interest rate under § 846(c) for 2013, which is 2.16 percent, and by assuming all estimated salvage is recovered in the middle of the calendar year.
.02 These tables must be used by taxpayers irrespective of whether they elected to discount unpaid losses using their own experience under § 846(e).
.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 approved by the National Association of Insurance Commissioners. 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, is permitted but not required. Rev. Proc. 2002–74 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 therein.
