December 28, 2009 

Rev. Proc. 2009-55


SECTION 1. PURPOSE

This revenue procedure prescribes the loss payment patterns and discount factors for the 2009 accident year. These factors will be used for computing discounted unpaid losses under § 846 of the Internal Revenue Code. See Rev. Proc. 2008-10, 2008-3 I.R.B. 290, for background concerning the loss payment patterns and application of the discount factors.

SECTION 2. SCOPE

This revenue procedure applies to any taxpayer that is required to discount its unpaid losses under § 846 for a line of business using discount factors published by the Secretary.

SECTION 3. TABLES OF DISCOUNT FACTORS

.01 The following tables present separately for each line of business the discount factors under § 846 for accident year 2009. All the discount factors presented in this section were determined using the applicable interest rate under § 846(c) for 2009, which is 4.06 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 2005 annual statement. See Rev. Proc. 2008-10, section 2, for additional background on discounting under § 846 and the use of the Secretary’s tables.

.03 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. The tables separately provide discount factors for taxpayers who elect to use the composite method of section V of Notice 88-100. See Rev. Proc. 2002-74, 2002-2 C.B. 980.
