Sec. 1.846-1  Application of discount factors.

    (a) In general--(1) Rules. A separate series of discount factors are 
computed for, and applied, to undiscounted unpaid losses attributable to 
each accident year of each line of business shown on the annual 
statement (as defined by section 846(f)(3)) filed by that taxpayer for 
the calendar year ending with or within the taxable year of the 
taxpayer. See Sec. 1.832-4(b) relating to the determination of unpaid 
losses. Paragraph (b) of this section provides rules relating to 
applicable discount factors and Sec. 1.846-3(b) contains guidance 
relating to discount factors applicable to accident years prior to the 
1987 accident year. Once a taxpayer applies a series of discount factors 
to unpaid losses attributable to an accident year of a line of business, 
that series of discount factors must be applied to discount the unpaid 
losses for that accident year for that line of business for all future 
taxable years. The discount factors cannot be changed to reflect a 
change in the taxpayer's loss payment pattern during

[[Page 750]]

a subsequent year or to reflect a different interest rate assumption. 
However, discount factors may be changed for taxpayers who elect to use 
their own historical loss payment pattern, if information upon which the 
pattern is based is adjusted upon examination by the district director.
    (2) Examples. The following examples illustrate the principles of 
paragraph (a)(1) of this section:

    Example 1. A taxpayer discounts unpaid losses attributable to all 
accident years prior to 1992 using discount factors published by the 
Service. In 1992, the taxpayer elects, under Sec. 1.846-2, to compute 
discount factors using its own historical loss payment pattern. The 
taxpayer must continue to discount unpaid losses attributable to pre-
1992 accident years using the discount factors published for those 
accident years by the Service.
    Example 2. On its annual statements through 1987, a taxpayer did not 
allocate unpaid losses attributable to proportional reinsurance to the 
line of business associated with the risks being reinsured. Beginning 
with the 1988 annual statement, the taxpayer allocated those losses for 
all accident years to the line of business being reinsured. The taxpayer 
must continue to discount the unpaid losses attributable to proportional 
reinsurance from pre-1988 accident years using the discount factors that 
were used in determining tax reserves for the 1987 tax year. (See 
paragraph (b)(3) of this section for rules relating to the application 
of discount factors to reinsurance unpaid losses.)

    (3) Increase in discounted unpaid losses shown on the annual 
statement. If the amount of unpaid losses shown on the annual statement 
is determined on a discounted basis, and the extent to which the unpaid 
losses were discounted can be determined on the basis of information 
disclosed on or with the annual statement, the amount of the unpaid 
losses to which the discount factors are applied shall be determined 
without regard to any reduction attributable to the discounting 
reflected on the annual statement.
    (4) Increase in unpaid losses which take into account estimated 
salvage recoverable. If the amount of unpaid losses shown on the annual 
statement reflects a reduction for estimated salvage recoverable and the 
extent to which the unpaid losses were reduced by estimated salvage 
recoverable is appropriately disclosed as required by Sec. 1.832-
4(d)(2), the amount of unpaid losses shall be determined without regard 
to the reduction for salvage recoverable.
    (b) Applicable discount factors--(1) In general. Except as otherwise 
provided in section 846(f)(6) (relating to certain accident and health 
lines of business), in Sec. 1.846-2 (relating to a taxpayer's election 
to use its own historical loss payment pattern), in this paragraph (b), 
or in other guidance published in the Internal Revenue Bulletin, the 
following factors must be used--
    (i) Discount factors published by the Service. If the Service has 
published discount factors for a line of business, a taxpayer must 
discount unpaid losses attributable to that line by applying those 
discount factors; and
    (ii) Composite discount factors. If the Service has not published 
discount factors for a line of business, a taxpayer must discount unpaid 
losses attributable to that line by applying composite discount factors.
    (iii) Annual statement changes. If the groupings of individual lines 
of business on the annual statement changes, taxpayers must discount the 
unpaid losses on the resulting lines of business with the discounting 
patterns that would have applied to those unpaid losses based on their 
annual statement classification prior to the change.
    (2) Title insurance company reserves. A title insurance company may 
only take into account case reserves (relating to claims which have been 
reported to the insurance company). Unless the Service publishes other 
guidance, the reserves must be discounted using the ``Miscellaneous 
Casualty'' discount factors published by the Service. Section 832(b)(8) 
provides rules for determining the discounted unearned premiums of a 
title insurance company.
    (3) Reinsurance business--(i) Proportional reinsurance for accident 
years after 1987. For the 1988 accident year and subsequent accident 
years, unpaid losses for proportional reinsurance must be discounted 
using discount factors applicable to the line of business to which those 
unpaid losses are allocated as required on the annual statement.
    (ii) Non-proportional reinsurance--(A) Accident years after 1991. 
For the 1992 accident year and subsequent accident

[[Page 751]]

years, unpaid losses for non-proportional reinsurance must be discounted 
using the applicable discount factors published by the Service for the 
appropriate reinsurance line of business.
    (B) Accident years 1988 through 1991. For the 1988, 1989, 1990, and 
1991 accident years unpaid losses for non-proportional reinsurance must 
be discounted using composite discount factors.
    (iii) Reinsurance for accident years before 1988. If on its annual 
statement a taxpayer does not allocate unpaid losses to the applicable 
line of business for proportional or nonproportional reinsurance 
attributable to the 1987 accident year or a prior accident year, those 
losses must be discounted using composite discount factors. If on its 
annual statement a taxpayer allocates to the underlying line of business 
reinsurance unpaid losses that are attributable to the 1987 accident 
year or a prior accident year, those losses must be discounted using 
discount factors applicable to the underlying line of business.
    (iv) 90 percent exception. For purposes of Sec. 1.846-1(b)(3) (ii) 
and (iii), if more than 90 percent of all the unallocated losses of a 
taxpayer for an accident year relate to one underlying line of business, 
the taxpayer must discount all unallocable reinsurance unpaid losses 
attributable to that accident year using the discount factors published 
by the Service for the underlying line of business.
    (4) International business. For any accident year, unpaid losses 
which are attributable to international business must be discounted 
using composite discount factors unless more than 90 percent of all 
losses for that accident year relate to one underlying line of business. 
If more than 90 percent of all losses for an accident year relate to one 
underlying line of business, the taxpayer must discount the losses 
attributable to that accident year using discount factors published by 
the Service for the underlying line of business.
    (5) Composite discount factors. For purposes of the regulations 
under section 846, ``composite discount factors'' means the series of 
discount factors published annually by the Service determined on the 
basis of the appropriate composite loss payment pattern.
