Sec. 1.1275-4  Contingent payment debt instruments.

    (a) Applicability--(1) In general. Except as provided in paragraph 
(a)(2) of this section, this section applies to any debt instrument that 
provides for one or more contingent payments. In general, paragraph (b) 
of this section applies to a contingent payment debt instrument that is 
issued for money or publicly traded property and paragraph (c) of this 
section applies to a contingent payment debt instrument that is issued 
for nonpublicly traded property. Paragraph (d) of this section provides 
special rules for tax-exempt obligations. See Sec. 1.1275-6 for a 
taxpayer's treatment of a contingent payment debt instrument and a 
hedge.
    (2) Exceptions. This section does not apply to--
    (i) A debt instrument that has an issue price determined under 
section 1273(b)(4) (e.g., a debt instrument subject to section 483);
    (ii) A variable rate debt instrument (as defined in Sec. 1.1275-5);
    (iii) A debt instrument subject to Sec. 1.1272-1(c) (a debt 
instrument that provides for certain contingencies) or Sec. 1.1272-1(d) 
(a debt instrument that provides for a fixed yield);
    (iv) A debt instrument subject to section 988 (except as provided in 
section 988 and the regulations thereunder);
    (v) A debt instrument to which section 1272(a)(6) applies (certain 
interests in or mortgages held by a REMIC, and certain other debt 
instruments with payments subject to acceleration);
    (vi) A debt instrument (other than a tax-exempt obligation) 
described in section 1272(a)(2) (e.g., U.S. savings bonds, certain loans 
between natural persons, and short-term taxable obligations);
    (vii) An inflation-indexed debt instrument (as defined in Sec. 
1.1275-7); or
    (viii) A debt instrument issued pursuant to a plan or arrangement 
if--
    (A) The plan or arrangement is created by a state statute;
    (B) A primary objective of the plan or arrangement is to enable the 
participants to pay for the costs of post-secondary education for 
themselves or their designated beneficiaries; and
    (C) Contingent payments on the debt instrument are related to such 
objective.
    (3) Insolvency and default. A payment is not contingent merely 
because of the possibility of impairment by insolvency, default, or 
similar circumstances.
    (4) Convertible debt instruments. A debt instrument does not provide 
for contingent payments merely because it provides for an option to 
convert the debt instrument into the stock of the issuer, into the stock 
or debt of a related party (within the meaning of section 267(b) or 
707(b)(1)), or into cash or other property in an amount equal to the 
approximate value of such stock or debt.
    (5) Remote and incidental contingencies. A payment is not a 
contingent payment merely because of a contingency that, as of the issue 
date, is either remote or incidental. See Sec. 1.1275-2(h) for the 
treatment of remote and incidental contingencies.
    (b) Noncontingent bond method--(1) Applicability. The noncontingent 
bond method described in this paragraph (b) applies to a contingent 
payment debt instrument that has an issue price determined under Sec. 
1.1273-2 (e.g., a contingent payment debt instrument that is issued for 
money or publicly traded property).
    (2) In general. Under the noncontingent bond method, interest on a 
debt instrument must be taken into account whether or not the amount of 
any payment is fixed or determinable in the taxable year. The amount of 
interest

[[Page 554]]

that is taken into account for each accrual period is determined by 
constructing a projected payment schedule for the debt instrument and 
applying rules similar to those for accruing OID on a noncontingent debt 
instrument. If the actual amount of a contingent payment is not equal to 
the projected amount, appropriate adjustments are made to reflect the 
difference.
    (3) Description of method. The following steps describe how to 
compute the amount of income, deductions, gain, and loss under the 
noncontingent bond method:
    (i) Step one: Determine the comparable yield. Determine the 
comparable yield for the debt instrument under the rules of paragraph 
(b)(4) of this section. The comparable yield is determined as of the 
debt instrument's issue date.
    (ii) Step two: Determine the projected payment schedule. Determine 
the projected payment schedule for the debt instrument under the rules 
of paragraph (b)(4) of this section. The projected payment schedule is 
determined as of the issue date and remains fixed throughout the term of 
the debt instrument (except under paragraph (b)(9)(ii) of this section, 
which applies to a payment that is fixed more than 6 months before it is 
due).
    (iii) Step three: Determine the daily portions of interest. 
Determine the daily portions of interest on the debt instrument for a 
taxable year as follows. The amount of interest that accrues in each 
accrual period is the product of the comparable yield of the debt 
instrument (properly adjusted for the length of the accrual period) and 
the debt instrument's adjusted issue price at the beginning of the 
accrual period. See paragraph (b)(7)(ii) of this section to determine 
the adjusted issue price of the debt instrument. The daily portions of 
interest are determined by allocating to each day in the accrual period 
the ratable portion of the interest that accrues in the accrual period. 
Except as modified by paragraph (b)(3)(iv) of this section, the daily 
portions of interest are includible in income by a holder for each day 
in the holder's taxable year on which the holder held the debt 
instrument and are deductible by the issuer for each day during the 
issuer's taxable year on which the issuer was primarily liable on the 
debt instrument.
    (iv) Step four: Adjust the amount of income or deductions for 
differences between projected and actual contingent payments. Make 
appropriate adjustments to the amount of income or deductions 
attributable to the debt instrument in a taxable year for any 
differences between projected and actual contingent payments. See 
paragraph (b)(6) of this section to determine the amount of an 
adjustment and the treatment of the adjustment.
    (4) Comparable yield and projected payment schedule. This paragraph 
(b)(4) provides rules for determining the comparable yield and projected 
payment schedule for a debt instrument. The comparable yield and 
projected payment schedule must be supported by contemporaneous 
documentation showing that both are reasonable, are based on reliable, 
complete, and accurate data, and are made in good faith.
    (i) Comparable yield--(A) In general. Except as provided in 
paragraph (b)(4)(i)(B) of this section, the comparable yield for a debt 
instrument is the yield at which the issuer would issue a fixed rate 
debt instrument with terms and conditions similar to those of the 
contingent payment debt instrument (the comparable fixed rate debt 
instrument), including the level of subordination, term, timing of 
payments, and general market conditions. For example, if a Sec. 1.1275-
6 hedge (or the substantial equivalent) is available, the comparable 
yield is the yield on the synthetic fixed rate debt instrument that 
would result if the issuer entered into the Sec. 1.1275-6 hedge. If a 
Sec. 1.1275-6 hedge (or the substantial equivalent) is not available, 
but similar fixed rate debt instruments of the issuer trade at a price 
that reflects a spread above a benchmark rate, the comparable yield is 
the sum of the value of the benchmark rate on the issue date and the 
spread. In determining the comparable yield, no adjustments are made for 
the riskiness of the contingencies or the liquidity of the debt 
instrument. The comparable yield must be a reasonable yield for the 
issuer and must not be less than the applicable Federal rate (based on 
the overall maturity of the debt instrument).

[[Page 555]]

    (B) Presumption for certain debt instruments. This paragraph 
(b)(4)(i)(B) applies to a debt instrument if the instrument provides for 
one or more contingent payments not based on market information and the 
instrument is part of an issue that is marketed or sold in substantial 
part to persons for whom the inclusion of interest under this paragraph 
(b) is not expected to have a substantial effect on their U.S. tax 
liability. If this paragraph (b)(4)(i)(B) applies to a debt instrument, 
the instrument's comparable yield is presumed to be the applicable 
Federal rate (based on the overall maturity of the debt instrument). A 
taxpayer may overcome this presumption only with clear and convincing 
evidence that the comparable yield for the debt instrument should be a 
specific yield (determined using the principles in paragraph 
(b)(4)(i)(A) of this section) that is higher than the applicable Federal 
rate. The presumption may not be overcome with appraisals or other 
valuations of nonpublicly traded property. Evidence used to overcome the 
presumption must be specific to the issuer and must not be based on 
comparable issuers or general market conditions.
    (ii) Projected payment schedule. The projected payment schedule for 
a debt instrument includes each noncontingent payment and an amount for 
each contingent payment determined as follows:
    (A) Market-based payments. If a contingent payment is based on 
market information (a market-based payment), the amount of the projected 
payment is the forward price of the contingent payment. The forward 
price of a contingent payment is the amount one party would agree, as of 
the issue date, to pay an unrelated party for the right to the 
contingent payment on the settlement date (e.g., the date the contingent 
payment is made). For example, if the right to a contingent payment is 
substantially similar to an exchange-traded option, the forward price is 
the spot price of the option (the option premium) compounded at the 
applicable Federal rate from the issue date to the date the contingent 
payment is due.
    (B) Other payments. If a contingent payment is not based on market 
information (a non-market-based payment), the amount of the projected 
payment is the expected value of the contingent payment as of the issue 
date.
    (C) Adjustments to the projected payment schedule. The projected 
payment schedule must produce the comparable yield. If the projected 
payment schedule does not produce the comparable yield, the schedule 
must be adjusted consistent with the principles of this paragraph (b)(4) 
to produce the comparable yield. For example, the adjusted amounts of 
non-market-based payments must reasonably reflect the relative expected 
values of the payments and must not be set to accelerate or defer income 
or deductions. If the debt instrument contains both market-based and 
non-market-based payments, adjustments are generally made first to the 
non-market-based payments because more objective information is 
available for the market-based payments.
    (iii) Market information. For purposes of this paragraph (b), market 
information is any information on which an objective rate can be based 
under Sec. 1.1275-5(c) (1) or (2).
    (iv) Issuer/holder consistency. The issuer's projected payment 
schedule is used to determine the holder's interest accruals and 
adjustments. The issuer must provide the projected payment schedule to 
the holder in a manner consistent with the issuer disclosure rules of 
Sec. 1.1275-2(e). If the issuer does not create a projected payment 
schedule for a debt instrument or the issuer's projected payment 
schedule is unreasonable, the holder of the debt instrument must 
determine the comparable yield and projected payment schedule for the 
debt instrument under the rules of this paragraph (b)(4). A holder that 
determines its own projected payment schedule must explicitly disclose 
this fact and the reason why the holder set its own schedule (e.g., why 
the issuer's projected payment schedule is unreasonable). Unless 
otherwise prescribed by the Commissioner, the disclosure must be made on 
a statement attached to the holder's timely filed Federal income tax 
return for the taxable year that includes the acquisition date of the 
debt instrument.
    (v) Issuer's determination respected--(A) In general. If the issuer 
maintains

[[Page 556]]

the contemporaneous documentation required by this paragraph (b)(4), the 
issuer's determination of the comparable yield and projected payment 
schedule will be respected unless either is unreasonable.
    (B) Unreasonable determination. For purposes of paragraph 
(b)(4)(v)(A) of this section, a comparable yield or projected payment 
schedule generally will be considered unreasonable if it is set with a 
purpose to overstate, understate, accelerate, or defer interest accruals 
on the debt instrument. In a determination of whether a comparable yield 
or projected payment schedule is unreasonable, consideration will be 
given to whether the treatment of the debt instrument under this section 
is expected to have a substantial effect on the issuer's or holder's 
U.S. tax liability. For example, if a taxable issuer markets a debt 
instrument to a holder not subject to U.S. taxation, the comparable 
yield will be given close scrutiny and will not be respected unless 
contemporaneous documentation shows that the yield is not too high.
    (C) Exception. Paragraph (b)(4)(v)(A) of this section does not apply 
to a debt instrument subject to paragraph (b)(4)(i)(B) of this section 
(concerning a yield presumption for certain debt instruments that 
provide for non-market-based payments).
    (vi) Examples. The following examples illustrate the provisions of 
this paragraph (b)(4). In each example, assume that the instrument 
described is a debt instrument for Federal income tax purposes. No 
inference is intended, however, as to whether the instrument is a debt 
instrument for Federal income tax purposes.

    Example 1. Market-based payment--(i) Facts. On December 31, 1996, X 
corporation issues for $1,000,000 a debt instrument that matures on 
December 31, 2006. The debt instrument provides for annual payments of 
interest, beginning in 1997, at the rate of 6 percent and for a payment 
at maturity equal to $1,000,000 plus the excess, if any, of the price of 
10,000 shares of publicly traded stock in an unrelated corporation on 
the maturity date over $350,000, or less the excess, if any, of $350,000 
over the price of 10,000 shares of the stock on the maturity date. On 
the issue date, the forward price to purchase 10,000 shares of the stock 
on December 31, 2006, is $350,000.
    (ii) Comparable yield. Under paragraph (b)(4)(i) of this section, 
the debt instrument's comparable yield is the yield on the synthetic 
debt instrument that would result if X corporation entered into a Sec. 
1.1275-6 hedge. A Sec. 1.1275-6 hedge in this case is a forward 
contract to purchase 10,000 shares of the stock on December 31, 2006. If 
X corporation entered into this hedge, the resulting synthetic debt 
instrument would yield 6 percent, compounded annually. Thus, the 
comparable yield on the debt instrument is 6 percent, compounded 
annually.
    (iii) Projected payment schedule. Under paragraph (b)(4)(ii) of this 
section, the projected payment schedule for the debt instrument consists 
of 10 annual payments of $60,000 and a projected amount for the 
contingent payment at maturity. Because the right to the contingent 
payment is based on market information, the projected amount of the 
contingent payment is the forward price of the payment. The right to the 
contingent payment is substantially similar to a right to a payment of 
$1,000,000 combined with a cash-settled forward contract for the 
purchase of 10,000 shares of the stock for $350,000 on December 31, 
2006. Because the forward price to purchase 10,000 shares of the stock 
on December 31, 2006, is $350,000, the amount to be received or paid 
under the forward contract is projected to be zero. As a result, the 
projected amount of the contingent payment at maturity is $1,000,000, 
consisting of the $1,000,000 base amount and no additional amount to be 
received or paid under the forward contract.
    (A) Assume, alternatively, that on the issue date the forward price 
to purchase 10,000 shares of the stock on December 31, 2006, is 
$370,000. If X corporation entered into a Sec. 1.1275-6 hedge (a 
forward contract to purchase the shares for $370,000), the resulting 
synthetic debt instrument would yield 6.15 percent, compounded annually. 
Thus, the comparable yield on the debt instrument is 6.15 percent, 
compounded annually. The projected payment schedule for the debt 
instrument consists of 10 annual payments of $60,000 and a projected 
amount for the contingent payment at maturity. The projected amount of 
the contingent payment is $1,020,000, consisting of the $1,000,000 base 
amount plus the excess $20,000 of the forward price of the stock over 
the purchase price of the stock under the forward contract.
    (B) Assume, alternatively, that on the issue date the forward price 
to purchase 10,000 shares of the stock on December 31, 2006, is 
$330,000. If X corporation entered into a Sec. 1.1275-6 hedge, the 
resulting synthetic debt instrument would yield 5.85 percent, compounded 
annually. Thus, the comparable yield on the debt instrument is 5.85 
percent, compounded annually. The projected payment schedule for the 
debt instrument consists of 10 annual payments of $60,000 and a 
projected amount for the contingent payment at maturity. The projected 
amount of

[[Page 557]]

the contingent payment is $980,000, consisting of the $1,000,000 base 
amount minus the excess $20,000 of the purchase price of the stock under 
the forward contract over the forward price of the stock.
    Example 2. Non-market-based payments--(i) Facts. On December 31, 
1996, Y issues to Z for $1,000,000 a debt instrument that matures on 
December 31, 2000. The debt instrument has a stated principal amount of 
$1,000,000, payable at maturity, and provides for payments on December 
31 of each year, beginning in 1997, of $20,000 plus 1 percent of Y's 
gross receipts, if any, for the year. On the issue date, Y has 
outstanding fixed rate debt instruments with maturities of 2 to 10 years 
that trade at a price that reflects an average of 100 basis points over 
Treasury bonds. These debt instruments have terms and conditions similar 
to those of the debt instrument. Assume that on December 31, 1996, 4-
year Treasury bonds have a yield of 6.5 percent, compounded annually, 
and that no Sec. 1.1275-6 hedge is available for the debt instrument. 
In addition, assume that the interest inclusions attributable to the 
debt instrument are expected to have a substantial effect on Z's U.S. 
tax liability.
    (ii) Comparable yield. The comparable yield for the debt instrument 
is equal to the value of the benchmark rate (i.e., the yield on 4-year 
Treasury bonds) on the issue date plus the spread. Thus, the debt 
instrument's comparable yield is 7.5 percent, compounded annually.
    (iii) Projected payment schedule. Y anticipates that it will have no 
gross receipts in 1997, but that it will have gross receipts in later 
years, and those gross receipts will grow each year for the next three 
years. Based on its business projections, Y believes that it is not 
unreasonable to expect that its gross receipts in 1999 and each year 
thereafter will grow by between 6 percent and 13 percent over the prior 
year. Thus, Y must take these expectations into account in establishing 
a projected payment schedule for the debt instrument that results in a 
yield of 7.5 percent, compounded annually. Accordingly, Y could 
reasonably set the following projected payment schedule for the debt 
instrument:

------------------------------------------------------------------------
                                               Noncontingent  Contingent
                     Date                         payment       payment
------------------------------------------------------------------------
12/31/1997...................................       $20,000           $0
12/31/1998...................................        20,000       70,000
12/31/1999...................................        20,000       75,600
12/31/2000...................................     1,020,000       83,850
------------------------------------------------------------------------

    (5) Qualified stated interest. No amounts payable on a debt 
instrument to which this paragraph (b) applies are qualified stated 
interest within the meaning of Sec. 1.1273-1(c).
    (6) Adjustments. This paragraph (b)(6) provides rules for the 
treatment of positive and negative adjustments under the noncontingent 
bond method. A taxpayer takes into account only those adjustments that 
occur during a taxable year while the debt instrument is held by the 
taxpayer or while the taxpayer is primarily liable on the debt 
instrument.
    (i) Determination of positive and negative adjustments. If the 
amount of a contingent payment is more than the projected amount of the 
contingent payment, the difference is a positive adjustment on the date 
of the payment. If the amount of a contingent payment is less than the 
projected amount of the contingent payment, the difference is a negative 
adjustment on the date of the payment (or on the scheduled date of the 
payment if the amount of the payment is zero).
    (ii) Treatment of net positive adjustments. The amount, if any, by 
which total positive adjustments on a debt instrument in a taxable year 
exceed the total negative adjustments on the debt instrument in the 
taxable year is a net positive adjustment. A net positive adjustment is 
treated as additional interest for the taxable year.
    (iii) Treatment of net negative adjustments. The amount, if any, by 
which total negative adjustments on a debt instrument in a taxable year 
exceed the total positive adjustments on the debt instrument in the 
taxable year is a net negative adjustment. A taxpayer's net negative 
adjustment on a debt instrument for a taxable year is treated as 
follows:
    (A) Reduction of interest accruals. A net negative adjustment first 
reduces interest for the taxable year that the taxpayer would otherwise 
account for on the debt instrument under paragraph (b)(3)(iii) of this 
section.
    (B) Ordinary income or loss. If the net negative adjustment exceeds 
the interest for the taxable year that the taxpayer would otherwise 
account for on the debt instrument under paragraph (b)(3)(iii) of this 
section, the excess is treated as ordinary loss by a holder and ordinary 
income by an issuer. However, the amount treated as ordinary loss by a 
holder is limited to the

[[Page 558]]

amount by which the holder's total interest inclusions on the debt 
instrument exceed the total amount of the holder's net negative 
adjustments treated as ordinary loss on the debt instrument in prior 
taxable years. The amount treated as ordinary income by an issuer is 
limited to the amount by which the issuer's total interest deductions on 
the debt instrument exceed the total amount of the issuer's net negative 
adjustments treated as ordinary income on the debt instrument in prior 
taxable years.
    (C) Carryforward. If the net negative adjustment exceeds the sum of 
the amounts treated by the taxpayer as a reduction of interest and as 
ordinary income or loss (as the case may be) on the debt instrument for 
the taxable year, the excess is a negative adjustment carryforward for 
the taxable year. In general, a taxpayer treats a negative adjustment 
carryforward for a taxable year as a negative adjustment on the debt 
instrument on the first day of the succeeding taxable year. However, if 
a holder of a debt instrument has a negative adjustment carryforward on 
the debt instrument in a taxable year in which the debt instrument is 
sold, exchanged, or retired, the negative adjustment carryforward 
reduces the holder's amount realized on the sale, exchange, or 
retirement. If an issuer of a debt instrument has a negative adjustment 
carryforward on the debt instrument for a taxable year in which the debt 
instrument is retired, the issuer takes the negative adjustment 
carryforward into account as ordinary income.
    (D) Treatment under section 67. A net negative adjustment is not 
subject to section 67 (the 2-percent floor on miscellaneous itemized 
deductions).
    (iv) Cross-references. If a holder has a basis in a debt instrument 
that is different from the debt instrument's adjusted issue price, the 
holder may have additional positive or negative adjustments under 
paragraph (b)(9)(i) of this section. If the amount of a contingent 
payment is fixed more than 6 months before the date it is due, the 
amount and timing of the adjustment are determined under paragraph 
(b)(9)(ii) of this section.
    (7) Adjusted issue price, adjusted basis, and retirement--(i) In 
general. If a debt instrument is subject to the noncontingent bond 
method, this paragraph (b)(7) provides rules to determine the adjusted 
issue price of the debt instrument, the holder's basis in the debt 
instrument, and the treatment of any scheduled or unscheduled 
retirements. In general, because any difference between the actual 
amount of a contingent payment and the projected amount of the payment 
is taken into account as an adjustment to income or deduction, the 
projected payments are treated as the actual payments for purposes of 
making adjustments to issue price and basis and determining the amount 
of any contingent payment made on a scheduled retirement.
    (ii) Definition of adjusted issue price. The adjusted issue price of 
a debt instrument is equal to the debt instrument's issue price, 
increased by the interest previously accrued on the debt instrument 
under paragraph (b)(3)(iii) of this section (determined without regard 
to any adjustments taken into account under paragraph (b)(3)(iv) of this 
section), and decreased by the amount of any noncontingent payment and 
the projected amount of any contingent payment previously made on the 
debt instrument. See paragraph (b)(9)(ii) of this section for special 
rules that apply when a contingent payment is fixed more than 6 months 
before it is due.
    (iii) Adjustments to basis. A holder's basis in a debt instrument is 
increased by the interest previously accrued by the holder on the debt 
instrument under paragraph (b)(3)(iii) of this section (determined 
without regard to any adjustments taken into account under paragraph 
(b)(3)(iv) of this section), and decreased by the amount of any 
noncontingent payment and the projected amount of any contingent payment 
previously made on the debt instrument to the holder. See paragraph 
(b)(9)(i) of this section for special rules that apply when basis is 
different from adjusted issue price and paragraph (b)(9)(ii) of this 
section for special rules that apply when a contingent payment is fixed 
more than 6 months before it is due.

[[Page 559]]

    (iv) Scheduled retirements. For purposes of determining the amount 
realized by a holder and the repurchase price paid by the issuer on the 
scheduled retirement of a debt instrument, a holder is treated as 
receiving, and the issuer is treated as paying, the projected amount of 
any contingent payment due at maturity. If the amount paid or received 
is different from the projected amount, see paragraph (b)(6) of this 
section for the treatment of the difference by the taxpayer. Under 
paragraph (b)(6)(iii)(C) of this section, the amount realized by a 
holder on the retirement of a debt instrument is reduced by any negative 
adjustment carryforward determined in the taxable year of the 
retirement.
    (v) Unscheduled retirements. An unscheduled retirement of a debt 
instrument (or the receipt of a pro-rata prepayment that is treated as a 
retirement of a portion of a debt instrument under Sec. 1.1275-2(f)) is 
treated as a repurchase of the debt instrument (or a pro-rata portion of 
the debt instrument) by the issuer from the holder for the amount paid 
by the issuer to the holder.
    (vi) Examples. The following examples illustrate the provisions of 
paragraphs (b) (6) and (7) of this section. In each example, assume that 
the instrument described is a debt instrument for Federal income tax 
purposes. No inference is intended, however, as to whether the 
instrument is a debt instrument for Federal income tax purposes.

    Example 1. Treatment of positive and negative adjustments--(i) 
Facts. On December 31, 1996, Z, a calendar year taxpayer, purchases a 
debt instrument subject to this paragraph (b) at original issue for 
$1,000. The debt instrument's comparable yield is 10 percent, compounded 
annually, and the projected payment schedule provides for payments of 
$500 on December 31, 1997 (consisting of a noncontingent payment of $375 
and a projected amount of $125) and $660 on December 31, 1998 
(consisting of a noncontingent payment of $600 and a projected amount of 
$60). The debt instrument is a capital asset in the hands of Z.
    (ii) Adjustment in 1997. Based on the projected payment schedule, 
Z's total daily portions of interest on the debt instrument are $100 for 
1997 (issue price of $1,000 x 10 percent). Assume that the payment 
actually made on December 31, 1997, is $375, rather than the projected 
$500. Under paragraph (b)(6)(i) of this section, Z has a negative 
adjustment of $125 on December 31, 1997, attributable to the difference 
between the amount of the actual payment and the amount of the projected 
payment. Because Z has no positive adjustments for 1997, Z has a net 
negative adjustment of $125 on the debt instrument for 1997. This net 
negative adjustment reduces to zero the $100 total daily portions of 
interest Z would otherwise include in income in 1997. Accordingly, Z has 
no interest income on the debt instrument for 1997. Because Z had no 
interest inclusions on the debt instrument for prior taxable years, the 
remaining $25 of the net negative adjustment is a negative adjustment 
carryforward for 1997 that results in a negative adjustment of $25 on 
January 1, 1998.
    (iii) Adjustment to issue price and basis. Z's total daily portions 
of interest on the debt instrument are $100 for 1997. The adjusted issue 
price of the debt instrument and Z's adjusted basis in the debt 
instrument are increased by this amount, despite the fact that Z does 
not include this amount in income because of the net negative adjustment 
for 1997. In addition, the adjusted issue price of the debt instrument 
and Z's adjusted basis in the debt instrument are decreased on December 
31, 1997, by the projected amount of the payment on that date ($500). 
Thus, on January 1, 1998, Z's adjusted basis in the debt instrument and 
the adjusted issue price of the debt instrument are $600.
    (iv) Adjustments in 1998. Based on the projected payment schedule, 
Z's total daily portions of interest are $60 for 1998 (adjusted issue 
price of $600 x 10 percent). Assume that the payment actually made on 
December 31, 1998, is $700, rather than the projected $660. Under 
paragraph (b)(6)(i) of this section, Z has a positive adjustment of $40 
on December 31, 1998, attributable to the difference between the amount 
of the actual payment and the amount of the projected payment. Because Z 
also has a negative adjustment of $25 on January 1, 1998, Z has a net 
positive adjustment of $15 on the debt instrument for 1998 (the excess 
of the $40 positive adjustment over the $25 negative adjustment). As a 
result, Z has $75 of interest income on the debt instrument for 1998 
(the $15 net positive adjustment plus the $60 total daily portions of 
interest that are taken into account by Z in that year).
    (v) Retirement. Based on the projected payment schedule, Z's 
adjusted basis in the debt instrument immediately before the payment at 
maturity is $660 ($600 plus $60 total daily portions of interest for 
1998). Even though Z receives $700 at maturity, for purposes of 
determining the amount realized by Z on retirement of the debt 
instrument, Z is treated as receiving the projected amount of the 
contingent payment on December 31, 1998. Therefore, Z is treated as 
receiving $660 on December 31, 1998. Because Z's adjusted basis

[[Page 560]]

in the debt instrument immediately before its retirement is $660, Z 
recognizes no gain or loss on the retirement.
    Example 2. Negative adjustment carryforward for year of sale--(i) 
Facts. Assume the same facts as in Example 1 of this paragraph 
(b)(7)(vi), except that Z sells the debt instrument on January 1, 1998, 
for $630.
    (ii) Gain on sale. On the date the debt instrument is sold, Z's 
adjusted basis in the debt instrument is $600. Because Z has a negative 
adjustment of $25 on the debt instrument on January 1, 1998, and has no 
positive adjustments on the debt instrument in 1998, Z has a net 
negative adjustment for 1998 of $25. Because Z has not included in 
income any interest on the debt instrument, the entire $25 net negative 
adjustment is a negative adjustment carryforward for the taxable year of 
the sale. Under paragraph (b)(6)(iii)(C) of this section, the $25 
negative adjustment carryforward reduces the amount realized by Z on the 
sale of the debt instrument from $630 to $605. Thus, Z has a gain on the 
sale of $5 ($605-$600). Under paragraph (b)(8)(i) of this section, the 
gain is treated as interest income.
    Example 3. Negative adjustment carryforward for year of retirement--
(i) Facts. Assume the same facts as in Example 1 of this paragraph 
(b)(7)(vi), except that the payment actually made on December 31, 1998, 
is $615, rather than the projected $660.
    (ii) Adjustments in 1998. Under paragraph (b)(6)(i) of this section, 
Z has a negative adjustment of $45 on December 31, 1998, attributable to 
the difference between the amount of the actual payment and the amount 
of the projected payment. In addition, Z has a negative adjustment of 
$25 on January 1, 1998. See Example 1(ii) of this paragraph (b)(7)(vi). 
Because Z has no positive adjustments in 1998, Z has a net negative 
adjustment of $70 for 1998. This net negative adjustment reduces to zero 
the $60 total daily portions of interest Z would otherwise include in 
income for 1998. Therefore, Z has no interest income on the debt 
instrument for 1998. Because Z had no interest inclusions on the debt 
instrument for 1997, the remaining $10 of the net negative adjustment is 
a negative adjustment carryforward for 1998 that reduces the amount 
realized by Z on retirement of the debt instrument.
    (iii) Loss on retirement. Immediately before the payment at 
maturity, Z's adjusted basis in the debt instrument is $660. Under 
paragraph (b)(7)(iv) of this section, Z is treated as receiving the 
projected amount of the contingent payment, or $660, as the payment at 
maturity. Under paragraph (b)(6)(iii)(C) of this section, however, this 
amount is reduced by any negative adjustment carryforward determined for 
the taxable year of retirement to calculate the amount Z realizes on 
retirement of the debt instrument. Thus, Z has a loss of $10 on the 
retirement of the debt instrument, equal to the amount by which Z's 
adjusted basis in the debt instrument ($660) exceeds the amount Z 
realizes on the retirement of the debt instrument ($660 minus the $10 
negative adjustment carryforward). Under paragraph (b)(8)(ii) of this 
section, the loss is a capital loss.

    (8) Character on sale, exchange, or retirement--(i) Gain. Any gain 
recognized by a holder on the sale, exchange, or retirement of a debt 
instrument subject to this paragraph (b) is interest income.
    (ii) Loss. Any loss recognized by a holder on the sale, exchange, or 
retirement of a debt instrument subject to this paragraph (b) is 
ordinary loss to the extent that the holder's total interest inclusions 
on the debt instrument exceed the total net negative adjustments on the 
debt instrument the holder took into account as ordinary loss. Any 
additional loss is treated as loss from the sale, exchange, or 
retirement of the debt instrument. However, any loss that would 
otherwise be ordinary under this paragraph (b)(8)(ii) and that is 
attributable to the holder's basis that could not be amortized under 
section 171(b)(4) is loss from the sale, exchange, or retirement of the 
debt instrument.
    (iii) Special rule if there are no remaining contingent payments on 
the debt instrument--(A) In general. Notwithstanding paragraphs (b)(8) 
(i) and (ii) of this section, if, at the time of the sale, exchange, or 
retirement of the debt instrument, there are no remaining contingent 
payments due on the debt instrument under the projected payment 
schedule, any gain or loss recognized by the holder is gain or loss from 
the sale, exchange, or retirement of the debt instrument. See paragraph 
(b)(9)(ii) of this section to determine whether there are no remaining 
contingent payments on a debt instrument that provides for fixed but 
deferred contingent payments.
    (B) Exception for certain positive adjustments. Notwithstanding 
paragraph (b)(8)(iii)(A) of this section, if a positive adjustment on a 
debt instrument is spread under paragraph (b)(9)(ii) (F) or (G) of this 
section, any gain recognized by the holder on the sale, exchange, or 
retirement of the instrument is treated as interest income to the extent 
of the positive adjustment

[[Page 561]]

that has not yet been accrued and included in income by the holder.
    (iv) Examples. The following examples illustrate the provisions of 
this paragraph (b)(8). In each example, assume that the instrument 
described is a debt instrument for Federal income tax purposes. No 
inference is intended, however, as to whether the instrument is a debt 
instrument for Federal income tax purposes.

    Example 1. Gain on sale--(i) Facts. On January 1, 1998, D, a 
calendar year taxpayer, sells a debt instrument that is subject to 
paragraph (b) of this section for $1,350. The projected payment schedule 
for the debt instrument provides for contingent payments after January 
1, 1998. On January 1, 1998, D has an adjusted basis in the debt 
instrument of $1,200. In addition, D has a negative adjustment 
carryforward of $50 for 1997 that, under paragraph (b)(6)(iii)(C) of 
this section, results in a negative adjustment of $50 on January 1, 
1998. D has no positive adjustments on the debt instrument on January 1, 
1998.
    (ii) Character of gain. Under paragraph (b)(6) of this section, the 
$50 negative adjustment on January 1, 1998, results in a negative 
adjustment carryforward for 1998, the taxable year of the sale of the 
debt instrument. Under paragraph (b)(6)(iii)(C) of this section, the 
negative adjustment carryforward reduces the amount realized by D on the 
sale of the debt instrument from $1,350 to $1,300. As a result, D 
realizes a $100 gain on the sale of the debt instrument, equal to the 
$1,300 amount realized minus D's $1,200 adjusted basis in the debt 
instrument. Under paragraph (b)(8)(i) of this section, the gain is 
interest income to D.
    Example 2. Loss on sale--(i) Facts. On December 31, 1996, E, a 
calendar year taxpayer, purchases a debt instrument at original issue 
for $1,000. The debt instrument is a capital asset in the hands of E. 
The debt instrument provides for a single payment on December 31, 1998 
(the maturity date of the instrument), of $1,000 plus an amount based on 
the increase, if any, in the price of a specified commodity over the 
term of the instrument. The comparable yield for the debt instrument is 
9.54 percent, compounded annually, and the projected payment schedule 
provides for a payment of $1,200 on December 31, 1998. Based on the 
projected payment schedule, the total daily portions of interest are $95 
for 1997 and $105 for 1998.
    (ii) Ordinary loss. Assume that E sells the debt instrument for 
$1,050 on December 31, 1997. On that date, E has an adjusted basis in 
the debt instrument of $1,095 ($1,000 original basis, plus total daily 
portions of $95 for 1997). Therefore, E realizes a $45 loss on the sale 
of the debt instrument ($1,050-$1,095). The loss is ordinary to the 
extent E's total interest inclusions on the debt instrument ($95) exceed 
the total net negative adjustments on the instrument that E took into 
account as an ordinary loss. Because E has not had any net negative 
adjustments on the debt instrument, the $45 loss is an ordinary loss.
    (iii) Capital loss. Alternatively, assume that E sells the debt 
instrument for $990 on December 31, 1997. E realizes a $105 loss on the 
sale of the debt instrument ($990 - $1,095). The loss is ordinary to the 
extent E's total interest inclusions on the debt instrument ($95) exceed 
the total net negative adjustments on the instrument that E took into 
account as an ordinary loss. Because E has not had any net negative 
adjustments on the debt instrument, $95 of the $105 loss is an ordinary 
loss. The remaining $10 of the $105 loss is a capital loss.

    (9) Operating rules. The rules of this paragraph (b)(9) apply to a 
debt instrument subject to the noncontingent bond method notwithstanding 
any other rule of this paragraph (b).
    (i) Basis different from adjusted issue price. This paragraph 
(b)(9)(i) provides rules for a holder whose basis in a debt instrument 
is different from the adjusted issue price of the debt instrument (e.g., 
a subsequent holder that purchases the debt instrument for more or less 
than the instrument's adjusted issue price).
    (A) General rule. The holder accrues interest under paragraph 
(b)(3)(iii) of this section and makes adjustments under paragraph 
(b)(3)(iv) of this section based on the projected payment schedule 
determined as of the issue date of the debt instrument. However, upon 
acquiring the debt instrument, the holder must reasonably allocate any 
difference between the adjusted issue price and the basis to daily 
portions of interest or projected payments over the remaining term of 
the debt instrument. Allocations are taken into account under paragraphs 
(b)(9)(i) (B) and (C) of this section.
    (B) Basis greater than adjusted issue price. If the holder's basis 
in the debt instrument exceeds the debt instrument's adjusted issue 
price, the amount of the difference allocated to a daily portion of 
interest or to a projected payment is treated as a negative adjustment 
on the date the daily portion accrues or the payment is made. On the 
date of the adjustment, the

[[Page 562]]

holder's adjusted basis in the debt instrument is reduced by the amount 
the holder treats as a negative adjustment under this paragraph 
(b)(9)(i)(B). See paragraph (b)(9)(ii)(E) of this section for a special 
rule that applies when a contingent payment is fixed more than 6 months 
before it is due.
    (C) Basis less than adjusted issue price. If the holder's basis in 
the debt instrument is less than the debt instrument's adjusted issue 
price, the amount of the difference allocated to a daily portion of 
interest or to a projected payment is treated as a positive adjustment 
on the date the daily portion accrues or the payment is made. On the 
date of the adjustment, the holder's adjusted basis in the debt 
instrument is increased by the amount the holder treats as a positive 
adjustment under this paragraph (b)(9)(i)(C). See paragraph 
(b)(9)(ii)(E) of this section for a special rule that applies when a 
contingent payment is fixed more than 6 months before it is due.
    (D) Premium and discount rules do not apply. The rules for accruing 
premium and discount in sections 171, 1272(a)(7), 1276, and 1281 do not 
apply. Other rules of those sections, such as section 171(b)(4), 
continue to apply to the extent relevant.
    (E) Safe harbor for exchange listed debt instruments. If the debt 
instrument is exchange listed property (within the meaning of Sec. 
1.1273-2(f)(2)), it is reasonable for the holder to allocate any 
difference between the holder's basis and the adjusted issue price of 
the debt instrument pro-rata to daily portions of interest (as 
determined under paragraph (b)(3)(iii) of this section) over the 
remaining term of the debt instrument. A pro-rata allocation is not 
reasonable, however, to the extent the holder's yield on the debt 
instrument, determined after taking into account the amounts allocated 
under this paragraph (b)(9)(i)(E), is less than the applicable Federal 
rate for the instrument. For purposes of the preceding sentence, the 
applicable Federal rate for the debt instrument is determined as if the 
purchase date were the issue date and the remaining term of the 
instrument were the term of the instrument.
    (F) Examples. The following examples illustrate the provisions of 
this paragraph (b)(9)(i). In each example, assume that the instrument 
described is a debt instrument for Federal income tax purposes. No 
inference is intended, however, as to whether the instrument is a debt 
instrument for Federal income tax purposes. In addition, assume that 
each instrument is not exchange listed property.

    Example 1. Basis greater than adjusted issue price--(i) Facts. On 
July 1, 1998, Z purchases for $1,405 a debt instrument that matures on 
December 31, 1999, and promises to pay on the maturity date $1,000 plus 
the increase, if any, in the price of a specified amount of a commodity 
from the issue date to the maturity date. The debt instrument was 
originally issued on December 31, 1996, for an issue price of $1,000. 
The comparable yield for the debt instrument is 10.25 percent, 
compounded semiannually, and the projected payment schedule for the debt 
instrument (determined as of the issue date) provides for a single 
payment at maturity of $1,350. At the time of the purchase, the debt 
instrument has an adjusted issue price of $1,162, assuming semiannual 
accrual periods ending on December 31 and June 30 of each year. The 
increase in the value of the debt instrument over its adjusted issue 
price is due to an increase in the expected amount of the contingent 
payment and not to a decrease in market interest rates. The debt 
instrument is a capital asset in the hands of Z. Z is a calendar year 
taxpayer.
    (ii) Allocation of the difference between basis and adjusted issue 
price. Z's basis in the debt instrument on July 1, 1998, is $1,405. 
Under paragraph (b)(9)(i)(A) of this section, Z allocates the $243 
difference between basis ($1,405) and adjusted issue price ($1,162) to 
the contingent payment at maturity. Z's allocation of the difference 
between basis and adjusted issue price is reasonable because the 
increase in the value of the debt instrument over its adjusted issue 
price is due to an increase in the expected amount of the contingent 
payment.
    (iii) Treatment of debt instrument for 1998. Based on the projected 
payment schedule, $60 of interest accrues on the debt instrument from 
July 1, 1998 to December 31, 1998 (the product of the debt instrument's 
adjusted issue price on July 1, 1998 ($1,162) and the comparable yield 
properly adjusted for the length of the accrual period (10.25 percent/
2)). Z has no net negative or positive adjustments for 1998. Thus, Z 
includes in income $60 of total daily portions of interest for 1998. On 
December 31, 1998, Z's adjusted basis in the debt instrument is $1,465 
($1,405 original basis, plus total daily portions of $60 for 1998).
    (iv) Effect of allocation to contingent payment at maturity. Assume 
that the payment

[[Page 563]]

actually made on December 31, 1999, is $1,400, rather than the projected 
$1,350. Thus, under paragraph (b)(6)(i) of this section, Z has a 
positive adjustment of $50 on December 31, 1999. In addition, under 
paragraph (b)(9)(i)(B) of this section, Z has a negative adjustment of 
$243 on December 31, 1999, which is attributable to the difference 
between Z's basis in the debt instrument on July 1, 1998, and the 
instrument's adjusted issue price on that date. As a result, Z has a net 
negative adjustment of $193 for 1999. This net negative adjustment 
reduces to zero the $128 total daily portions of interest Z would 
otherwise include in income in 1999. Accordingly, Z has no interest 
income on the debt instrument for 1999. Because Z had $60 of interest 
inclusions for 1998, $60 of the remaining $65 net negative adjustment is 
treated by Z as an ordinary loss for 1999. The remaining $5 of the net 
negative adjustment is a negative adjustment carryforward for 1999 that 
reduces the amount realized by Z on the retirement of the debt 
instrument from $1,350 to $1,345.
    (v) Loss at maturity. On December 31, 1999, Z's basis in the debt 
instrument is $1,350 ($1,405 original basis, plus total daily portions 
of $60 for 1998 and $128 for 1999, minus the negative adjustment of 
$243). As a result, Z realizes a loss of $5 on the retirement of the 
debt instrument (the difference between the amount realized on the 
retirement ($1,345) and Z's adjusted basis in the debt instrument 
($1,350)). Under paragraph (b)(8)(ii) of this section, the $5 loss is 
treated as loss from the retirement of the debt instrument. 
Consequently, Z realizes a total loss of $65 on the debt instrument for 
1999 (a $60 ordinary loss and a $5 capital loss).
    Example 2. Basis less than adjusted issue price--(i) Facts. On 
January 1, 1999, Y purchases for $910 a debt instrument that pays 7 
percent interest semiannually on June 30 and December 31 of each year, 
and that promises to pay on December 31, 2001, $1,000 plus or minus $10 
times the positive or negative difference, if any, between a specified 
amount and the value of an index on December 31, 2001. However, the 
payment on December 31, 2001, may not be less than $650. The debt 
instrument was originally issued on December 31, 1996, for an issue 
price of $1,000. The comparable yield for the debt instrument is 9.80 
percent, compounded semiannually, and the projected payment schedule for 
the debt instrument (determined as of the issue date) provides for 
semiannual payments of $35 and a contingent payment at maturity of 
$1,175. On January 1, 1999, the debt instrument has an adjusted issue 
price of $1,060, assuming semiannual accrual periods ending on December 
31 and June 30 of each year. Y is a calendar year taxpayer.
    (ii) Allocation of the difference between basis and adjusted issue 
price. Y's basis in the debt instrument on January 1, 1999, is $910. 
Under paragraph (b)(9)(i)(A) of this section, Y must allocate the $150 
difference between basis ($910) and adjusted issue price ($1,060) to 
daily portions of interest or to projected payments. These amounts will 
be positive adjustments taken into account at the time the daily 
portions accrue or the payments are made.
    (A) Assume that, because of a decrease in the relevant index, the 
expected value of the payment at maturity has declined by about 9 
percent. Based on forward prices on January 1, 1999, Y determines that 
approximately $105 of the difference between basis and adjusted issue 
price is allocable to the contingent payment. Y allocates the remaining 
$45 to daily portions of interest on a pro-rata basis (i.e., the amount 
allocated to an accrual period equals the product of $45 and a fraction, 
the numerator of which is the total daily portions for the accrual 
period and the denominator of which is the total daily portions 
remaining on the debt instrument on January 1, 1999). This allocation is 
reasonable.
    (B) Assume alternatively that, based on yields of comparable debt 
instruments and its purchase price for the debt instrument, Y determines 
that an appropriate yield for the debt instrument is 13 percent, 
compounded semiannually. Based on this determination, Y allocates $55.75 
of the difference between basis and adjusted issue price to daily 
portions of interest as follows: $15.19 to the daily portions of 
interest for the taxable year ending December 31, 1999; $18.40 to the 
daily portions of interest for the taxable year ending December 31, 
2000; and $22.16 to the daily portions of interest for the taxable year 
ending December 31, 2001. Y allocates the remaining $94.25 to the 
contingent payment at maturity. This allocation is reasonable.

    (ii) Fixed but deferred contingent payments. This paragraph 
(b)(9)(ii) provides rules that apply when the amount of a contingent 
payment becomes fixed before the payment is due. For purposes of 
paragraph (b) of this section, if a contingent payment becomes fixed 
within the 6-month period ending on the due date of the payment, the 
payment is treated as a contingent payment even after the payment is 
fixed. If a contingent payment becomes fixed more than 6 months before 
the payment is due, the following rules apply to the debt instrument.
    (A) Determining adjustments. The amount of the adjustment 
attributable to the contingent payment is equal to the difference 
between the present value of the amount that is fixed and the present 
value of the projected

[[Page 564]]

amount of the contingent payment. The present value of each amount is 
determined by discounting the amount from the date the payment is due to 
the date the payment becomes fixed, using a discount rate equal to the 
comparable yield on the debt instrument. The adjustment is treated as a 
positive or negative adjustment, as appropriate, on the date the 
contingent payment becomes fixed. See paragraph (b)(9)(ii)(G) of this 
section to determine the timing of the adjustment if all remaining 
contingent payments on the debt instrument become fixed substantially 
contemporaneously.
    (B) Payment schedule. The contingent payment is no longer treated as 
a contingent payment after the date the amount of the payment becomes 
fixed. On the date the contingent payment becomes fixed, the projected 
payment schedule for the debt instrument is modified prospectively to 
reflect the fixed amount of the payment. Therefore, no adjustment is 
made under paragraph (b)(3)(iv) of this section when the contingent 
payment is actually made.
    (C) Accrual period. Notwithstanding the determination under Sec. 
1.1272-1(b)(1)(ii) of accrual periods for the debt instrument, an 
accrual period ends on the day the contingent payment becomes fixed, and 
a new accrual period begins on the day after the day the contingent 
payment becomes fixed.
    (D) Adjustments to basis and adjusted issue price. The amount of any 
positive adjustment on a debt instrument determined under paragraph 
(b)(9)(ii)(A) of this section increases the adjusted issue price of the 
instrument and the holder's adjusted basis in the instrument. Similarly, 
the amount of any negative adjustment on a debt instrument determined 
under paragraph (b)(9)(ii)(A) of this section decreases the adjusted 
issue price of the instrument and the holder's adjusted basis in the 
instrument.
    (E) Basis different from adjusted issue price. If a holder's basis 
in a debt instrument exceeds the debt instrument's adjusted issue price, 
the amount allocated to a projected payment under paragraph (b)(9)(i) of 
this section is treated as a negative adjustment on the date the payment 
becomes fixed. If a holder's basis in a debt instrument is less than the 
debt instrument's adjusted issue price, the amount allocated to a 
projected payment under paragraph (b)(9)(i) of this section is treated 
as a positive adjustment on the date the payment becomes fixed.
    (F) Special rule for certain contingent interest payments. 
Notwithstanding paragraph (b)(9)(ii)(A) of this section, this paragraph 
(b)(9)(ii)(F) applies to contingent stated interest payments that are 
adjusted to compensate for contingencies regarding the reasonableness of 
the debt instrument's stated rate of interest. For example, this 
paragraph (b)(9)(ii)(F) applies to a debt instrument that provides for 
an increase in the stated rate of interest if the credit quality of the 
issuer or liquidity of the debt instrument deteriorates. Contingent 
stated interest payments of this type are recognized over the period to 
which they relate in a reasonable manner.
    (G) Special rule when all contingent payments become fixed. 
Notwithstanding paragraph (b)(9)(ii)(A) of this section, if all the 
remaining contingent payments on a debt instrument become fixed 
substantially contemporaneously, any positive or negative adjustments on 
the instrument are taken into account in a reasonable manner over the 
period to which they relate. For purposes of the preceding sentence, a 
payment is treated as a fixed payment if all remaining contingencies 
with respect to the payment are remote or incidental (within the meaning 
of Sec. 1.1275-2(h)).
    (H) Example. The following example illustrates the provisions of 
this paragraph (b)(9)(ii). In this example, assume that the instrument 
described is a debt instrument for Federal income tax purposes. No 
inference is intended, however, as to whether the instrument is a debt 
instrument for Federal income tax purposes.

    Example: Fixed but deferred payments--(i) Facts. On December 31, 
1996, B, a calendar year taxpayer, purchases a debt instrument at 
original issue for $1,000. The debt instrument matures on December 31, 
2002, and provides for a payment of $1,000 at maturity. In addition, on 
December 31, 1999, and December 31, 2002, the debt instrument provides 
for payments equal to the excess of the average

daily value of an index for the 6-month period ending on September 30 of 
the preceding year over a specified amount. The debt instrument's 
comparable yield is 10 percent, compounded annually, and the 
instrument's projected payment schedule consists of a payment of $250 on 
December 31, 1999, and a payment of $1,439 on December 31, 2002. B uses 
annual accrual periods.
    (ii) Interest accrual for 1997. Based on the projected payment 
schedule, B includes a total of $100 of daily portions of interest in 
income in 1997. B's adjusted basis in the debt instrument and the debt 
instrument's adjusted issue price on December 31, 1997, is $1,100.
    (iii) Interest accrual for 1998--(A) Adjustment. Based on the 
projected payment schedule, B would include $110 of total daily portions 
of interest in income in 1998. However, assume that on September 30, 
1998, the payment due on December 31, 1999, fixes at $300, rather than 
the projected $250. Thus, on September 30, 1998, B has an adjustment 
equal to the difference between the present value of the $300 fixed 
amount and the present value of the $250 projected amount of the 
contingent payment. The present values of the two payments are 
determined by discounting each payment from the date the payment is due 
(December 31, 1999) to the date the payment becomes fixed (September 30, 
1998), using a discount rate equal to 10 percent, compounded annually. 
The present value of the fixed payment is $266.30 and the present value 
of the projected amount of the contingent payment is $221.91. Thus, on 
September 30, 1998, B has a positive adjustment of $44.39 ($266.30-
$221.91).
    (B) Effect of adjustment. Under paragraph (b)(9)(ii)(C) of this 
section, B's accrual period ends on September 30, 1998. The daily 
portions of interest on the debt instrument for the period from January 
1, 1998 to September 30, 1998 total $81.51. The adjusted issue price of 
the debt instrument and B's adjusted basis in the debt instrument are 
thus increased over this period by $125.90 (the sum of the daily 
portions of interest of $81.51 and the positive adjustment of $44.39 
made at the end of the period) to $1,225.90. For purposes of all future 
accrual periods, including the new accrual period from October 1, 1998, 
to December 31, 1998, the debt instrument's projected payment schedule 
is modified to reflect a fixed payment of $300 on December 31, 1999. 
Based on the new adjusted issue price of the debt instrument and the new 
projected payment schedule, the yield on the debt instrument does not 
change.
    (C) Interest accrual for 1998. Based on the modified projected 
payment schedule, $29.56 of interest accrues during the accrual period 
that ends on December 31, 1998. Because B has no other adjustments 
during 1998, the $44.39 positive adjustment on September 30, 1998, 
results in a net positive adjustment for 1998, which is additional 
interest for that year. Thus, B includes $155.46 ($81.51+$29.56+$44.39) 
of interest in income in 1998. B's adjusted basis in the debt instrument 
and the debt instrument's adjusted issue price on December 31, 1998, is 
$1,255.46 ($1,225.90 from the end of the prior accrual period plus 
$29.56 total daily portions for the current accrual period).

    (iii) Timing contingencies. This paragraph (b)(9)(iii) provides 
rules for debt instruments that have payments that are contingent as to 
time.
    (A) Treatment of certain options. If a taxpayer has an unconditional 
option to put or call the debt instrument, to exchange the debt 
instrument for other property, or to extend the maturity date of the 
debt instrument, the projected payment schedule is determined by using 
the principles of Sec. 1.1272-1(c)(5).
    (B) Other timing contingencies. [Reserved]
    (iv) Cross-border transactions--(A) Allocation of deductions. For 
purposes of Sec. 1.861-8, the holder of a debt instrument shall treat 
any deduction or loss treated as an ordinary loss under paragraph 
(b)(6)(iii)(B) or (b)(8)(ii) of this section as a deduction that is 
definitely related to the class of gross income to which income from 
such debt instrument belongs. Accordingly, if a U.S. person holds a debt 
instrument issued by a related controlled foreign corporation and, 
pursuant to section 904(d)(3) and the regulations thereunder, any 
interest accrued by such U.S. person with respect to such debt 
instrument would be treated as foreign source general limitation income, 
any deductions relating to a net negative adjustment will reduce the 
U.S. person's foreign source general limitation income. The holder shall 
apply the general rules relating to allocation and apportionment of 
deductions to any other deduction or loss realized by the holder with 
respect to the debt instrument.
    (B) Investments in United States real property. Notwithstanding 
paragraph (b)(8)(i) of this section, gain on the sale, exchange, or 
retirement of a debt instrument that is a United States real property 
interest is treated as gain for purposes of sections 897, 1445, and 
6039C.
    (v) Coordination with subchapter M and related provisions. For 
purposes of sections 852(c)(2) and 4982 and Sec. 1.852-11,

[[Page 566]]

any positive adjustment, negative adjustment, income, or loss on a debt 
instrument that occurs after October 31 of a taxable year is treated in 
the same manner as foreign currency gain or loss that is attributable to 
a section 988 transaction.
    (vi) Coordination with section 1092. A holder treats a negative 
adjustment and an issuer treats a positive adjustment as a loss with 
respect to a position in a straddle if the debt instrument is a position 
in a straddle and the contingency (or any portion of the contingency) to 
which the adjustment relates would be part of the straddle if entered 
into as a separate position.
    (c) Method for debt instruments not subject to the noncontingent 
bond method--(1) Applicability. This paragraph (c) applies to a 
contingent payment debt instrument (other than a tax-exempt obligation) 
that has an issue price determined under Sec. 1.1274-2. For example, 
this paragraph (c) generally applies to a contingent payment debt 
instrument that is issued for nonpublicly traded property.
    (2) Separation into components. If paragraph (c) of this section 
applies to a debt instrument (the overall debt instrument), the 
noncontingent payments are subject to the rules in paragraph (c)(3) of 
this section, and the contingent payments are accounted for separately 
under the rules in paragraph (c)(4) of this section.
    (3) Treatment of noncontingent payments. The noncontingent payments 
are treated as a separate debt instrument. The issue price of the 
separate debt instrument is the issue price of the overall debt 
instrument, determined under Sec. 1.1274-2(g). No interest payments on 
the separate debt instrument are qualified stated interest payments 
(within the meaning of Sec. 1.1273-1(c)) and the de minimis rules of 
section 1273(a)(3) and Sec. 1.1273-1(d) do not apply to the separate 
debt instrument.
    (4) Treatment of contingent payments--(i) In general. Except as 
provided in paragraph (c)(4)(iii) of this section, the portion of a 
contingent payment treated as interest under paragraph (c)(4)(ii) of 
this section is includible in gross income by the holder and deductible 
from gross income by the issuer in their respective taxable years in 
which the payment is made.
    (ii) Characterization of contingent payments as principal and 
interest--(A) General rule. A contingent payment is treated as a payment 
of principal in an amount equal to the present value of the payment, 
determined by discounting the payment at the test rate from the date the 
payment is made to the issue date. The amount of the payment in excess 
of the amount treated as principal under the preceding sentence is 
treated as a payment of interest.
    (B) Test rate. The test rate used for purposes of paragraph 
(c)(4)(ii)(A) of this section is the rate that would be the test rate 
for the overall debt instrument under Sec. 1.1274-4 if the term of the 
overall debt instrument began on the issue date of the overall debt 
instrument and ended on the date the contingent payment is made. 
However, in the case of a contingent payment that consists of a payment 
of stated principal accompanied by a payment of stated interest at a 
rate that exceeds the test rate determined under the preceding sentence, 
the test rate is the stated interest rate.
    (iii) Certain delayed contingent payments--(A) General rule. 
Notwithstanding paragraph (c)(4)(ii) of this section, if a contingent 
payment becomes fixed more than 6 months before the payment is due, the 
issuer and holder are treated as if the issuer had issued a separate 
debt instrument on the date the payment becomes fixed, maturing on the 
date the payment is due. This separate debt instrument is treated as a 
debt instrument to which section 1274 applies. The stated principal 
amount of this separate debt instrument is the amount of the payment 
that becomes fixed. An amount equal to the issue price of this debt 
instrument is characterized as interest or principal under the rules of 
paragraph (c)(4)(ii) of this section and accounted for as if this amount 
had been paid by the issuer to the holder on the date that the amount of 
the payment becomes fixed. To determine the issue price of the separate

[[Page 567]]

debt instrument, the payment is discounted at the test rate from the 
maturity date of the separate debt instrument to the date that the 
amount of the payment becomes fixed.
    (B) Test rate. The test rate used for purposes of paragraph 
(c)(4)(iii)(A) of this section is determined in the same manner as the 
test rate under paragraph (c)(4)(ii)(B) of this section is determined 
except that the date the contingent payment is due is used rather than 
the date the contingent payment is made.
    (5) Basis different from adjusted issue price. This paragraph (c)(5) 
provides rules for a holder whose basis in a debt instrument is 
different from the instrument's adjusted issue price (e.g., a subsequent 
holder). This paragraph (c)(5), however, does not apply if the holder is 
reporting income under the installment method of section 453.
    (i) Allocation of basis. The holder must allocate basis to the 
noncontingent component (i.e., the right to the noncontingent payments) 
and to any separate debt instruments described in paragraph (c)(4)(iii) 
of this section in an amount up to the total of the adjusted issue price 
of the noncontingent component and the adjusted issue prices of the 
separate debt instruments. The holder must allocate the remaining basis, 
if any, to the contingent component (i.e., the right to the contingent 
payments).
    (ii) Noncontingent component. Any difference between the holder's 
basis in the noncontingent component and the adjusted issue price of the 
noncontingent component, and any difference between the holder's basis 
in a separate debt instrument and the adjusted issue price of the 
separate debt instrument, is taken into account under the rules for 
market discount, premium, and acquisition premium that apply to a 
noncontingent debt instrument.
    (iii) Contingent component. Amounts received by the holder that are 
treated as principal payments under paragraph (c)(4)(ii) of this section 
reduce the holder's basis in the contingent component. If the holder's 
basis in the contingent component is reduced to zero, any additional 
principal payments on the contingent component are treated as gain from 
the sale or exchange of the debt instrument. Any basis remaining on the 
contingent component on the date the final contingent payment is made 
increases the holder's adjusted basis in the noncontingent component 
(or, if there are no remaining noncontingent payments, is treated as 
loss from the sale or exchange of the debt instrument).
    (6) Treatment of a holder on sale, exchange, or retirement. This 
paragraph (c)(6) provides rules for the treatment of a holder on the 
sale, exchange, or retirement of a debt instrument subject to this 
paragraph (c). Under this paragraph (c)(6), the holder must allocate the 
amount received from the sale, exchange, or retirement of a debt 
instrument first to the noncontingent component and to any separate debt 
instruments described in paragraph (c)(4)(iii) of this section in an 
amount up to the total of the adjusted issue price of the noncontingent 
component and the adjusted issue prices of the separate debt 
instruments. The holder must allocate the remaining amount received, if 
any, to the contingent component.
    (i) Amount allocated to the noncontingent component. The amount 
allocated to the noncontingent component and any separate debt 
instruments is treated as an amount realized from the sale, exchange, or 
retirement of the noncontingent component or separate debt instrument.
    (ii) Amount allocated to the contingent component. The amount 
allocated to the contingent component is treated as a contingent payment 
that is made on the date of the sale, exchange, or retirement and is 
characterized as interest and principal under the rules of paragraph 
(c)(4)(ii) of this section.
    (7) Examples. The following examples illustrate the provisions of 
this paragraph (c). In each example, assume that the instrument 
described is a debt instrument for Federal income tax purposes. No 
inference is intended, however, as to whether the instrument is a debt 
instrument for Federal income tax purposes.

    Example 1. Contingent interest payments--(i) Facts. A owns 
Blackacre, unencumbered depreciable real estate. On January 1, 1997, A 
sells Blackacre to B. As consideration for the sale, B makes a 
downpayment of $1,000,000

[[Page 568]]

and issues to A a debt instrument that matures on December 31, 2001. The 
debt instrument provides for a payment of principal at maturity of 
$5,000,000 and a contingent payment of interest on December 31 of each 
year equal to a fixed percentage of the gross rents B receives from 
Blackacre in that year. Assume that the debt instrument is not issued in 
a potentially abusive situation. Assume also that on January 1, 1997, 
the short-term applicable Federal rate is 5 percent, compounded 
annually, and the mid-term applicable Federal rate is 6 percent, 
compounded annually.
    (ii) Determination of issue price. Under Sec. 1.1274-2(g), the 
issue price of the debt instrument is $3,736,291, which is the present 
value, as of the issue date, of the $5,000,000 noncontingent payment due 
at maturity, calculated using a discount rate equal to the mid-term 
applicable Federal rate. Under Sec. 1.1012-1(g)(1), B's basis in 
Blackacre on January 1, 1997, is $4,736,291 ($1,000,000 down payment 
plus the $3,736,291 issue price of the debt instrument).
    (iii) Noncontingent payment treated as separate debt instrument. 
Under paragraph (c)(3) of this section, the right to the noncontingent 
payment of principal at maturity is treated as a separate debt 
instrument. The issue price of this separate debt instrument is 
$3,736,291 (the issue price of the overall debt instrument). The 
separate debt instrument has a stated redemption price at maturity of 
$5,000,000 and, therefore, OID of $1,263,709.
    (iv) Treatment of contingent payments. Assume that the amount of 
contingent interest that is fixed and paid on December 31, 1997, is 
$200,000. Under paragraph (c)(4)(ii) of this section, this payment is 
treated as consisting of a payment of principal of $190,476, which is 
the present value of the payment, determined by discounting the payment 
at the test rate of 5 percent, compounded annually, from the date the 
payment is made to the issue date. The remainder of the $200,000 payment 
($9,524) is treated as interest. The additional amount treated as 
principal gives B additional basis in Blackacre on December 31, 1997. 
The portion of the payment treated as interest is includible in gross 
income by A and deductible by B in their respective taxable years in 
which December 31, 1997 occurs. The remaining contingent payments on the 
debt instrument are accounted for similarly, using a test rate of 5 
percent, compounded annually, for the contingent payments due on 
December 31, 1998, and December 31, 1999, and a test rate of 6 percent, 
compounded annually, for the contingent payments due on December 31, 
2000, and December 31, 2001.
    Example 2. Fixed but deferred payment--(i) Facts. The facts are the 
same as in paragraph (c)(7) Example 1 of this section, except that the 
contingent payment of interest that is fixed on December 31, 1997, is 
not payable until December 31, 2001, the maturity date.
    (ii) Treatment of deferred contingent payment. Assume that the 
amount of the payment that becomes fixed on December 31, 1997, is 
$200,000. Because this amount is not payable until December 31, 2001, 
under paragraph (c)(4)(iii) of this section, a separate debt instrument 
to which section 1274 applies is treated as issued by B on December 31, 
1997 (the date the payment is fixed). The maturity date of this separate 
debt instrument is December 31, 2001 (the date on which the payment is 
due). The stated principal amount of this separate debt instrument is 
$200,000, the amount of the payment that becomes fixed. The imputed 
principal amount of the separate debt instrument is $158,419, which is 
the present value, as of December 31, 1997, of the $200,000 payment, 
computed using a discount rate equal to the test rate of the overall 
debt instrument (6 percent, compounded annually). An amount equal to the 
issue price of the separate debt instrument is treated as an amount paid 
on December 31, 1997, and characterized as interest and principal under 
the rules of paragraph (c)(4)(ii) of this section. The amount of the 
deemed payment characterized as principal is equal to $150,875, which is 
the present value, as of January 1, 1997 (the issue date of the overall 
debt instrument), of the deemed payment, computed using a discount rate 
of 5 percent, compounded annually. The amount of the deemed payment 
characterized as interest is $7,544 ($158,419 -$150,875), which is 
includible in gross income by A and deductible by B in their respective 
taxable years in which December 31, 1997 occurs.

    (d) Rules for tax-exempt obligations--(1) In general. Except as 
modified by this paragraph (d), the noncontingent bond method described 
in paragraph (b) of this section applies to a tax-exempt obligation (as 
defined in section 1275(a)(3)) to which this section applies. Paragraph 
(d)(2) of this section applies to certain tax-exempt obligations that 
provide for interest-based payments or revenue-based payments and 
paragraph (d)(3) of this section applies to all other obligations. 
Paragraph (d)(4) of this section provides rules for a holder whose basis 
in a tax-exempt obligation is different from the adjusted issue price of 
the obligation.
    (2) Certain tax-exempt obligations with interest-based or revenue-
based payments--(i) Applicability. This paragraph (d)(2) applies to a 
tax-exempt obligation that provides for interest-based payments or 
revenue-based payments.
    (ii) Interest-based payments. A tax-exempt obligation provides for 
interest-based payments if the obligation would

[[Page 569]]

otherwise qualify as a variable rate debt instrument under Sec. 1.1275-
5 except that--
    (A) The obligation provides for more than one fixed rate;
    (B) The obligation provides for one or more caps, floors, or 
governors (or similar restrictions) that are fixed as of the issue date;
    (C) The interest on the obligation is not compounded or paid at 
least annually; or
    (D) The obligation provides for interest at one or more rates equal 
to the product of a qualified floating rate and a fixed multiple greater 
than zero and less than .65, or at one or more rates equal to the 
product of a qualified floating rate and a fixed multiple greater than 
zero and less than .65, increased or decreased by a fixed rate.
    (iii) Revenue-based payments. A tax-exempt obligation provides for 
revenue-based payments if the obligation--
    (A) Is issued to refinance (including a series of refinancings) an 
obligation (in a series of refinancings, the original obligation), the 
proceeds of which were used to finance a project or enterprise; and
    (B) Would otherwise qualify as a variable rate debt instrument under 
Sec. 1.1275-5 except that it provides for stated interest payments at 
least annually based on a single fixed percentage of the revenue, value, 
change in value, or other similar measure of the performance of the 
refinanced project or enterprise.
    (iv) Modifications to the noncontingent bond method. If a tax-exempt 
obligation is subject to this paragraph (d)(2), the following 
modifications to the noncontingent bond method described in paragraph 
(b) of this section apply to the obligation.
    (A) Daily portions and net positive adjustments. The daily portions 
of interest determined under paragraph (b)(3)(iii) of this section and 
any net positive adjustment on the obligation are interest for purposes 
of section 103.
    (B) Net negative adjustments. A net negative adjustment for a 
taxable year reduces the amount of tax-exempt interest the holder would 
otherwise account for on the obligation for the taxable year under 
paragraph (b)(3)(iii) of this section. If the net negative adjustment 
exceeds this amount, the excess is a nondeductible, noncapitalizable 
loss. If a regulated investment company (RIC) within the meaning of 
section 851 has a net negative adjustment in a taxable year that would 
be a nondeductible, noncapitalizable loss under the prior sentence, the 
RIC must use this loss to reduce its tax-exempt interest income on other 
tax-exempt obligations held during the taxable year.
    (C) Gains. Any gain recognized on the sale, exchange, or retirement 
of the obligation is gain from the sale or exchange of the obligation.
    (D) Losses. Any loss recognized on the sale, exchange, or retirement 
of the obligation is treated the same as a net negative adjustment under 
paragraph (d)(2)(iv)(B) of this section.
    (E) Special rule for losses and net negative adjustments. 
Notwithstanding paragraphs (d)(2)(iv) (B) and (D) of this section, on 
the sale, exchange, or retirement of the obligation, the holder may 
claim a loss from the sale or exchange of the obligation to the extent 
the holder has not received in cash or property the sum of its original 
investment in the obligation and any amounts included in income under 
paragraph (d)(4)(ii) of this section.
    (3) All other tax-exempt obligations--(i) Applicability. This 
paragraph (d)(3) applies to a tax-exempt obligation that is not subject 
to paragraph (d)(2) of this section.
    (ii) Modifications to the noncontingent bond method. If a tax-exempt 
obligation is subject to this paragraph (d)(3), the following 
modifications to the noncontingent bond method described in paragraph 
(b) of this section apply to the obligation.
    (A) Modification to projected payment schedule. The comparable yield 
for the obligation is the greater of the obligation's yield, determined 
without regard to the contingent payments, and the tax-exempt applicable 
Federal rate that applies to the obligation. The Internal Revenue 
Service publishes the tax-exempt applicable Federal rate for each month 
in the Internal Revenue Bulletin (see Sec. 601.601(d)(2)(ii) of this 
chapter).
    (B) Daily portions. The daily portions of interest determined under 
paragraph

[[Page 570]]

(b)(3)(iii) of this section are interest for purposes of section 103.
    (C) Adjustments. A net positive adjustment on the obligation is 
treated as gain to the holder from the sale or exchange of the 
obligation in the taxable year of the adjustment. A net negative 
adjustment on the obligation is treated as a loss to the holder from the 
sale or exchange of the obligation in the taxable year of the 
adjustment.
    (D) Gains and losses. Any gain or loss recognized on the sale, 
exchange, or retirement of the obligation is gain or loss from the sale 
or exchange of the obligation.
    (4) Basis different from adjusted issue price. This paragraph (d)(4) 
provides rules for a holder whose basis in a tax-exempt obligation is 
different from the adjusted issue price of the obligation. The rules of 
paragraph (b)(9)(i) of this section do not apply to tax-exempt 
obligations.
    (i) Basis greater than adjusted issue price. If the holder's basis 
in the obligation exceeds the obligation's adjusted issue price, the 
holder, upon acquiring the obligation, must allocate this difference to 
daily portions of interest on a yield to maturity basis over the 
remaining term of the obligation. The amount allocated to a daily 
portion of interest is not deductible by the holder. However, the 
holder's basis in the obligation is reduced by the amount allocated to a 
daily portion of interest on the date the daily portion accrues.
    (ii) Basis less than adjusted issue price. If the holder's basis in 
the obligation is less than the obligation's adjusted issue price, the 
holder, upon acquiring the obligation, must allocate this difference to 
daily portions of interest on a yield to maturity basis over the 
remaining term of the obligation. The amount allocated to a daily 
portion of interest is includible in income by the holder as ordinary 
income on the date the daily portion accrues. The holder's adjusted 
basis in the obligation is increased by the amount includible in income 
by the holder under this paragraph (d)(4)(ii) on the date the daily 
portion accrues.
    (iii) Premium and discount rules do not apply. The rules for 
accruing premium and discount in sections 171, 1276, and 1288 do not 
apply. Other rules of those sections continue to apply to the extent 
relevant.
    (e) Amounts treated as interest under this section. Amounts treated 
as interest under this section are treated as OID for all purposes of 
the Internal Revenue Code.
    (f) Effective date. This section applies to debt instruments issued 
on or after August 13, 1996.
