SECTION 1. PURPOSE
This revenue procedure prescribes unpaid loss discount factors for the 2018
accident year for use in computing discounted unpaid losses under § 846 of the Internal
Revenue Code. The unpaid loss discount factors also serve as salvage discount
factors for the 2018 accident year for use in computing discounted estimated salvage
recoverable under § 832. The discount factors prescribed herein were determined
under § 846, as amended by section 13523 of the Tax Cuts and Jobs Act, Pub. L. No.
115-97 (December 22, 2017) (“TCJA”), and proposed regulations under § 846 (REG-
103163-18) published in the Federal Register (83 FR 55646) on November 7, 2018 (the
“proposed regulations”). If necessary after the proposed regulations are published as
final regulations, the Department of the Treasury (the “Treasury Department”) and
Internal Revenue Service (“IRS”) intend to publish for each property and casualty line of
business revised unpaid loss discount factors for the 2018 accident year for use in
taxable years ending on or after the date the final regulations are published.
SECTION 2. BACKGROUND

2

.01 Modification of Discounting Rules
(1) Section 13523 of the TCJA amended § 846 for taxable years beginning after
December 31, 2017. Section 13523(a) and (b) of the TCJA amended the definition of
annual rate under § 846(c) and the computational rules for loss payment patterns under
§ 846(d), respectively. Section 13523(c) of the TCJA repealed the election that was
previously set forth in § 846(e) to use the taxpayer’s own historical loss payment pattern
instead of the pattern published by the Secretary.
ember 31, 2017. Section 13523(a) and (b) of the TCJA amended the definition of
annual rate under § 846(c) and the computational rules for loss payment patterns under
§ 846(d), respectively. Section 13523(c) of the TCJA repealed the election that was
previously set forth in § 846(e) to use the taxpayer’s own historical loss payment pattern
instead of the pattern published by the Secretary.
(2) Section 13523(e) of the TCJA provides the transitional rule for the application
of the amendments in the first taxable year beginning after December 31, 2017, and for
subsequent taxable years (the “TCJA transition rule”). Specifically, section 13523(e)
provides that, for the first taxable year beginning after December 31, 2017, the unpaid
losses and expenses unpaid (as defined in § 832(b)(5) and (6)) at the end of the
preceding taxable year, and the unpaid losses (as defined in §§ 805(a)(1) and
807(c)(2)) at the end of the preceding taxable year, are determined as if the
amendments made by section 13523 of the TCJA had applied to the unpaid losses and
expenses unpaid in the preceding taxable year and by using the interest rate and loss
payment patterns applicable to accident years ending with calendar year 2018. The
resulting adjustment (the “TCJA adjustment”), if any, is included in the taxpayer’s gross
income ratably over an eight year period (the “TCJA period of adjustment,” which is the
first taxable year beginning after December 31, 2017, and the seven succeeding taxable
years). Section 13523(e) also provides that, for subsequent taxable years, the
amendments made by section 13523 are applied with respect to unpaid losses and

3

expenses unpaid for accident years ending with or before calendar year 2018 by using
the interest rate and loss payment patterns applicable to accident years ending with
calendar year 2018. Loss payment patterns for the 2017 determination year were
previously prescribed in Rev. Proc. 2018-13, 2018-7 I.R.B. 356. In Rev. Proc
section 13523 are applied with respect to unpaid losses and

3

expenses unpaid for accident years ending with or before calendar year 2018 by using
the interest rate and loss payment patterns applicable to accident years ending with
calendar year 2018. Loss payment patterns for the 2017 determination year were
previously prescribed in Rev. Proc. 2018-13, 2018-7 I.R.B. 356. In Rev. Proc. 2018-13,
the Treasury Department and IRS also announced the intention to publish revised loss
payment patterns for the 2017 determination year in accordance with the TCJA
transition rule.
.02 Proposed Regulations
(1) Section 1.846-1(c) of the proposed regulations provides that the annual rate
for any calendar year is the average of the monthly spot interest rates on corporate
bonds with times to maturity of not more than seventeen and one-half years based on a
yield curve that reflects the average, for the most recent 60-month period ending before
the beginning of the calendar year, of monthly yields on corporate bonds described in
§ 430(h)(2)(D)(i).
(2) Section 1.846-1(d)(1) of the proposed regulations provides that, in general,
the loss payment pattern determined by the Secretary for each line of business is
determined by reference to the historical loss payment pattern applicable to such line of
business determined in accordance with the method of determination set forth in
§ 846(d)(2) and the computational rules prescribed in § 846(d)(3) on the basis of data
from annual statements described in § 846(d)(2)(A) and (B). However, under § 1.846-
1(d)(2) of the proposed regulations, the Secretary may adjust the loss payment pattern
for any line of business using a methodology described by the Secretary in other

4

published guidance if necessary to avoid negative payment amounts and otherwise
produce a stable pattern of positive discount factors less than one.
.03 Discount Factors for Accident Year 2018 and Prior Accident Years
of the proposed regulations, the Secretary may adjust the loss payment pattern
for any line of business using a methodology described by the Secretary in other

4

published guidance if necessary to avoid negative payment amounts and otherwise
produce a stable pattern of positive discount factors less than one.
.03 Discount Factors for Accident Year 2018 and Prior Accident Years
(1) The discount factors prescribed in this revenue procedure are determined by
using the applicable interest rate for accident year 2018 under § 846(c) and the
proposed regulations and revised loss payment patterns determined by the Secretary
for the 2017 determination year under § 846(d) and the proposed regulations.
(2) Pursuant to § 846(c) and the proposed regulations, the Secretary has
determined that the annual rate for the 2018 calendar year is 3.12 percent,
compounded semiannually. This annual rate is the average of the monthly spot rates
on corporate bonds with times to maturity of not more than seventeen and one-half
years based on a yield curve that reflects the average of monthly yields on corporate
bonds described in § 430(h)(2)(D)(i) for the period from January 2013 through
December 2017 (that is, the most recent 60-month period ending before the beginning
of the 2018 calendar year).1
(3) Pursuant to § 846(d) and the proposed regulations, the Secretary has
determined a revised loss payment pattern for each property and casualty line of
business for the 2017 determination year for use with respect to unpaid losses incurred
in accident year 2018 and prior accident years. The revised loss payment patterns for
the 2017 determination year are based, initially, on the aggregate loss payment

information reported on the 2015 annual statements of property and casualty insurance
companies and compiled by A.M. Best and Co. The lines of business for the 2017
determination year are the same as the lines of business for the 2012 determination
year. See Rev. Proc. 2012-44, 2012-49 I.R.B. 645. Losses are reported on the annual
statement net of losses on reinsurance ceded, but include losses on assumed
proportional reinsurance. Losses with respect to assumed non-proportional reinsurance
are reported in three separate lines of business (for property, liability, and financial
reinsurance). The loss data include defense, cost containment, adjusting, and other
loss expenses, but are not reduced for salvage and subrogation receipts.
(4) Pursuant to § 1.846-1(d)(2) of the proposed regulations, the Secretary may
adjust the loss payment pattern for any line of business using a methodology described
by the Secretary in other published guidance if necessary to avoid negative payment
amounts and otherwise produce a stable pattern of positive discount factors less than
one. For the 2017 determination year, only one line of business requires adjustments
under the proposed regulations. That line of business is Other Liability – Claims Made.
The initial payment pattern results in negative payment amounts for the fifth, seventh,
and ninth years after the accident year. Therefore, the payment amounts for the fourth
through the ninth year after the accident year are adjusted following the steps listed in
the preamble to the proposed regulations. See 83 FR 55646.
SECTION 3
That line of business is Other Liability – Claims Made.
The initial payment pattern results in negative payment amounts for the fifth, seventh,
and ninth years after the accident year. Therefore, the payment amounts for the fourth
through the ninth year after the accident year are adjusted following the steps listed in
the preamble to the proposed regulations. See 83 FR 55646.
SECTION 3. SCOPE
This revenue procedure applies to any taxpayer that is required to discount
unpaid losses under § 846 for a line of business using the discount factors published by

6

the Secretary, and also applies to any taxpayer that is required to discount estimated
salvage recoverable under § 832. This revenue procedure applies to taxable years
beginning after December 31, 2017.
SECTION 4. TABLES OF DISCOUNT FACTORS
.01 The tables in this section 4 present separately for each line of business the
unpaid loss discount factors under § 846 for use in the first taxable year beginning after
December 31, 2017, and for use in calculating the TCJA adjustment. All of the discount
factors presented in these tables are determined by using the applicable interest rate for
2018 under § 846(c) and the proposed regulations, which is 3.12 percent, compounded
semiannually, and the revised payment patterns for the 2017 determination year
determined by the Secretary under § 846(d) and the proposed regulations. 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 Tables 1 and 2 present separately for each line of business the unpaid loss
discount factors under § 846 for use in the first taxable year beginning after December
31, 2017
determined by the Secretary under § 846(d) and the proposed regulations. 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 Tables 1 and 2 present separately for each line of business the unpaid loss
discount factors under § 846 for use in the first taxable year beginning after December
31, 2017. Any taxpayer using discount factors prescribed in Tables 1 and 2 to compute
discounted unpaid losses under § 846 for its first taxable year beginning after December
31, 2017, must use the discount factors prescribed in Tables 1 and 2 with respect to all
of its property and casualty lines of business and, consistent with the TCJA transition
rule, must use the discount factors prescribed in Tables 1 and 2 for all accident years
ending with or before calendar year 2018. The taxpayer also must use the discount
factors prescribed in Tables 1 and 2 as the salvage discount factors for the 2018

7

accident year and all prior accident years for purposes of determining estimated salvage
recoverable under § 832 with respect to all of its property and casualty lines of business
for its first taxable year beginning after December 31, 2017.
.03 Consistent with the TCJA transition rule, any taxpayer using the discount
factors prescribed in Tables 1 and 2 for its first taxable year beginning after December
31, 2017, must, for that taxable year, use the discount factors prescribed in Tables 3
and 4 for purposes of determining the unpaid losses and expenses unpaid (as defined
in § 832(b)(5) and (6)) at the end of the preceding taxable year, and the unpaid losses
(as defined in §§ 805(a)(1) and 807(c)(2)) at the end of the preceding taxable year
2 for its first taxable year beginning after December
31, 2017, must, for that taxable year, use the discount factors prescribed in Tables 3
and 4 for purposes of determining the unpaid losses and expenses unpaid (as defined
in § 832(b)(5) and (6)) at the end of the preceding taxable year, and the unpaid losses
(as defined in §§ 805(a)(1) and 807(c)(2)) at the end of the preceding taxable year. The
taxpayer also must, for its first taxable year beginning after December 31, 2017, use the
unpaid loss discount factors prescribed in Tables 3 and 4 to determine the amount of
the TCJA adjustment to be taken into account in that taxable year and, unless revised
discount factors have been published, the amount of the TCJA adjustment to be taken
into account in subsequent taxable years.
.04 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 through 4 separately provide discount
factors for taxpayers who have elected to use the composite method of Notice 88-100.
See Rev. Proc. 2002-74, 2002-2 C.B. 980.

Use composite discount factors published for the relevant accident year.*

*The relevant accident year is the accident year that is ten years prior to the specified taxable year.

SECTION 6. REVISED DISCOUNT FACTORS
.01 If revised unpaid loss discount factors for the 2018 accident year are
published after final regulations are published in the Federal Register, the Treasury
Department and IRS propose to issue guidance providing that taxpayers must use, for
taxable years ending on or after the date the final regulations are published, the revised
discount factors for purposes of determining, for all accident years ending with or before
calendar year 2018, the unpaid losses and expenses unpaid (as defined in § 832(b)(5)
and (6)) and the unpaid losses (as defined in §§ 805(a)(1) and 807(c)(2)).
.02 The Treasury Department and IRS propose that such guidance would
instruct any taxpayer that used the discount factors prescribed in this revenue
procedure in a taxable year beginning after December 31, 2017, and that does not
amend the return filed for such taxable year to use the revised discount factors, to take
into account the difference between the amount of the TCJA adjustment determined
using the unpaid loss discount factors prescribed in this revenue procedure and the
amount of the TCJA adjustment determined using the revised unpaid loss discount
factors. The difference would be taken into account ratably over the taxable years
remaining in the TCJA period of adjustment, beginning with the first taxable year in
which the taxpayer uses the revised discount factors
etermined
using the unpaid loss discount factors prescribed in this revenue procedure and the
amount of the TCJA adjustment determined using the revised unpaid loss discount
factors. The difference would be taken into account ratably over the taxable years
remaining in the TCJA period of adjustment, beginning with the first taxable year in
which the taxpayer uses the revised discount factors.

17

.03 Such guidance would also instruct any taxpayer that used the discount
factors prescribed in this revenue procedure in a taxable year beginning after December
31, 2017, and that does not amend the return filed for such taxable year to use the
revised discount factors, to compute, with respect to the last taxable year in which the
discount factors prescribed in this revenue procedure were used, the adjustment to the
amount of the discounted unpaid losses under § 846 at the end of that taxable year and
the amount of discounted estimated salvage recoverable under § 832 at the end of that
taxable year due to computing those amounts using the revised discount factors rather
than the discount factors prescribed in this revenue procedure. The adjustment would
be computed as follows: (1) from discounted unpaid losses computed using the
discount factors prescribed in this revenue procedure subtract discounted unpaid losses
computed using the revised discount factors, and (2) to the result so obtained, add
estimated salvage computed using the revised discount factors and subtract estimated
salvage computed using the discount factors prescribed in this revenue procedure. A
positive adjustment would be taken into account as an addition to gross income, and a
negative adjustment would be taken into account as a reduction to gross income
ised discount factors, and (2) to the result so obtained, add
estimated salvage computed using the revised discount factors and subtract estimated
salvage computed using the discount factors prescribed in this revenue procedure. A
positive adjustment would be taken into account as an addition to gross income, and a
negative adjustment would be taken into account as a reduction to gross income. The
adjustment would be taken into account either (1) in the first taxable year in which the
taxpayer uses the revised discount factors, or (2) ratably over the taxable years
remaining in the TCJA period of adjustment, beginning with the first taxable year in
which the taxpayer uses the revised discount factors. For the first taxable year in which
a taxpayer uses the revised discount factors, the taxpayer would determine each of the
following as if the revised discount factors had applied in the preceding taxable year:

18

(1) the unpaid losses and expenses unpaid (as defined in § 832(b)(5) and (6)) at the
end of the preceding taxable year, (2) the unpaid losses (as defined in §§ 805(a)(1) and
807(c)(2)) at the end of the preceding taxable year, and (3) the estimated salvage
recoverable under § 832 at the end of the preceding taxable year.
