Part III – Administrative, Procedural, and›Rev. Proc. 2020-48
SECTION 3. DISCOUNT FACTORS
Internal Revenue Bulletin 2020-49 · 2026-10-03 edition · updated 2026-10-04 · United States
FOR THE 2020 ACCIDENT YEAR
.01 The tables in this section 3 present separately for each line of business the discount factors for losses incurred in the 2020 accident year for use by insurance companies in computing discounted unpaid losses under § 846 and estimated salvage recoverable under § 832. All of the discount factors presented in these ta
bles are determined by using the applicable interest rate for 2020 under § 846(c), which is 3.08 percent, compounded semiannually, and the payment patterns for the 2017 determination year determined by the Secretary under § 846(d). All of the discount factors presented in these tables are determined by assuming all loss payments occur in the middle of the calendar year.
.02 Section V of Notice 88-100, 1988-2 C.B. 439, sets forth a composite method for computing discounted unpaid losses for accident years that are not separately reported on the annual statement. Tables 1 and 2 separately provide discount factors for insurance companies that have elected to use the composite method of Notice 88100. See Rev. Proc. 2002-74, 2002-2 C.B. 980. The discount factors computed using the composite method are unrelated to the composite discount factors referred to in § 1.846-1(b)(1)(ii) and (4) of the Income Tax Regulations, which apply to lines of business for which the Secretary has not published discount factors. The composite discount factors for use with respect to such lines of business are labelled “Short-Tail Composite” (in Table 1, part B) and “Long-Tail Composite” (in Table 2, part B). The “Miscellaneous Casualty” discount factors referenced in § 1.8461(b)(2) are not set forth in tables, but are equivalent to the “Short-Tail Composite” discount factors.
