COMPUTATION OF TAXABLE INCOME--Table of Contents
 
Sec. 1.148-10  Anti-abuse rules and authority of Commissioner.

    (a) Abusive arbitrage device--(1) In general. Bonds of an issue are 
arbitrage bonds under section 148 if an abusive arbitrage device under 
paragraph (a)(2) of this section is used in connection with the issue. 
This paragraph (a) is to be applied and interpreted broadly to carry out 
the purposes of section 148, as further described in Sec. 1.148-0. 
Except as otherwise provided in paragraph (c) of this section, any 
action that is expressly permitted by section 148 or Secs. 1.148-1 
through 1.148-11 is not an abusive arbitrage device (e.g., investment in 
higher yielding investments during a permitted temporary period under 
section 148(c)).
    (2) Abusive arbitrage device defined. Any action is an abusive 
arbitrage device if the action has the effect of--
    (i) Enabling the issuer to exploit the difference between tax-exempt 
and taxable interest rates to obtain a material financial advantage; and
    (ii) Overburdening the tax-exempt bond market.
    (3) Exploitation of tax-exempt interest rates. An action may exploit 
tax-exempt interest rates under paragraph (a)(2) of this section as a 
result of an investment of any portion of the gross proceeds of an issue 
over any period of time, notwithstanding that, in the aggregate, the 
gross proceeds of the issue are not invested in higher yielding 
investments over the term of the issue.
    (4) Overburdening the tax-exempt market. An action overburdens the 
tax-exempt bond market under paragraph (a)(2)(ii) of this section if it 
results in issuing more bonds, issuing bonds earlier, or allowing bonds 
to remain outstanding longer than is otherwise reasonably necessary to 
accomplish the governmental purposes of the bonds, based on all the 
facts and circumstances. Whether an action is reasonably necessary to 
accomplish the governmental purposes of the bonds depends on whether the 
primary purpose of the transaction is a bona fide governmental purpose 
(e.g., an issue of refunding bonds to achieve a debt service 
restructuring that would be issued independent of any arbitrage 
benefit). An important factor bearing on this determination is whether 
the action would reasonably be taken to accomplish the governmental 
purpose of the issue if the interest on the issue were not excludable 
from gross income under section 103(a) (assuming that the hypothetical 
taxable interest rate would be the same as the actual tax-exempt 
interest rate). Factors evidencing an overissuance include the issuance 
of an issue the proceeds of which are reasonably expected to exceed by 
more than a minor portion the amount necessary to accomplish the 
governmental purposes of the issue, or an issue the proceeds of which 
are, in fact, substantially in excess of the amount of sale proceeds 
allocated to expenditures for the governmental purposes of the issue. 
One factor evidencing an early issuance is the issuance of bonds that do 
not qualify for a temporary period under Sec. 1.148-2(e)(2), (e)(3), or 
(e)(4). One factor evidencing that bonds may remain outstanding longer 
than necessary is a term that exceeds the safe harbors against the 
creation of replacement proceeds under Sec. 1.148-1(c)(4)(i)(B). These 
factors may be outweighed by other factors, however, such as bona fide 
cost underruns or long-term financial distress.
    (b) Consequences of overburdening the tax-exempt bond market--(1) In 
general. An issue that overburdens the tax-exempt bond market (within 
the meaning of paragraph (a)(4) of this section) is subject to the 
following special limitations--
    (i) Special yield restriction. Investments are subject to the 
definition of materially higher yield under Sec. 1.148-2(d) that is 
equal to one-thousandth of 1 percent. In addition, each investment is 
treated as a separate class of investments under Sec. 1.148-5(b)(2)(ii), 
the yield on which may not be blended with that of other investments.
    (ii) Certain regulatory provisions inapplicable. The provisions of 
Sec. 1.148-5(c) (relating to yield reduction payments) and Sec. 1.148-
5(e) (2) and (3) (relating to

[[Page 700]]

recovery of qualified administrative costs) do not apply.
    (iii) Restrictive expenditure rule. Proceeds are not allocated to 
expenditures unless the proceeds-spent-last rule under Sec. 1.148-
6(d)(3)(i) is satisfied, applied by treating those proceeds as proceeds 
to be used for restricted working capital expenditures. For this 
purpose, available amount includes a reasonable working capital reserve 
as defined in Sec. 1.148-6(d)(3)(iii)(B).
    (2) Application. The provisions of this paragraph (b) only apply to 
the portion of an issue that, as a result of actions taken (or actions 
not taken) after the issue date, overburdens the market for tax-exempt 
bonds, except that for an issue that is reasonably expected as of the 
issue date to overburden the market, those provisions apply to all of 
the gross proceeds of the issue.
    (c) Anti-abuse rules on excess gross proceeds of advance refunding 
issues--(1) In general. Except as otherwise provided in this paragraph 
(c), an abusive arbitrage device is used and bonds of an advance 
refunding issue are arbitrage bonds if the issue has excess gross 
proceeds.
    (2) Definition of excess gross proceeds. Excess gross proceeds means 
all gross proceeds of an advance refunding issue that exceed an amount 
equal to 1 percent of sale proceeds of the issue, other than gross 
proceeds allocable to--
    (i) Payment of principal, interest, or call premium on the prior 
issue;
    (ii) Payment of pre-issuance accrued interest on the refunding 
issue, and interest on the refunding issue that accrues for a period up 
to the completion date of any capital project for which the prior issue 
was issued, plus one year;
    (iii) A reasonably required reserve or replacement fund for the 
refunding issue or investment proceeds of such a fund;
    (iv) Payment of costs of issuance of the refunding issue;
    (v) Payment of administrative costs allocable to repaying the prior 
issue, carrying and repaying the refunding issue, or investments of the 
refunding issue;
    (vi) Transferred proceeds that will be used or maintained for the 
governmental purpose of the prior issue;
    (vii) Interest on purpose investments;
    (viii) Replacement proceeds in a sinking fund for the refunding 
issue;
    (ix) Qualified guarantee fees for the refunding issue or the prior 
issue; and
    (x) Fees for a qualified hedge for the refunding issue.
    (3) Special treatment of transferred proceeds. For purposes of this 
paragraph (c), all unspent proceeds of the prior issue as of the issue 
date of the refunding issue are treated as transferred proceeds of the 
advance refunding issue.
    (4) Special rule for crossover refundings. An advance refunding 
issue is not an issue of arbitrage bonds under this paragraph (c) if all 
excess gross proceeds of the refunding issue are used to pay interest 
that accrues on the refunding issue before the prior issue is 
discharged, and no gross proceeds of any refunding issue are used to pay 
interest on the prior issue or to replace funds used directly or 
indirectly to pay such interest (other than transferred proceeds used to 
pay interest on the prior issue that accrues for a period up to the 
completion date of the project for which the prior issue was issued, 
plus one year, or proceeds used to pay principal that is attributable to 
accrued original issue discount).
    (5) Special rule for gross refundings. This paragraph (c)(5) applies 
if an advance refunding issue (the series B issue) is used together with 
one or more other advance refunding issues (the series A issues) in a 
gross refunding of a prior issue, but only if the use of a gross 
refunding method is required under bond documents that were effective 
prior to November 6, 1992. These advance refunding issues are not 
arbitrage bonds under this paragraph (c) if--
    (i) All excess gross proceeds of the series B issue and each series 
A issue are investment proceeds used to pay principal and interest on 
the series B issue;
    (ii) At least 99 percent of all principal and interest on the series 
B issue is paid with proceeds of the series B and series A issues or 
with the earnings on other amounts in the refunding escrow for the prior 
issue;
    (iii) The series B issue is discharged not later than the prior 
issue; and

[[Page 701]]

    (iv) As of any date, the amount of gross proceeds of the series B 
issue allocated to expenditures does not exceed the aggregate amount of 
expenditures before that date for principal and interest on the series B 
issue, and administrative costs of carrying and repaying the series B 
issue, or of investments of the series B issue.
    (d) Examples. The provisions of this section are illustrated by the 
following examples:
    Example 1. Mortgage sale. In 1982, City issued its revenue issue 
(the 1982 issue) and lent the proceeds to Developer to finance a low-
income housing project under former section 103(b)(4)(A) of the 1954 
Code. In 1994, Developer encounters financial difficulties and 
negotiates with City to refund the 1982 issue. City issues $10 million 
in principal amount of its 8 percent bonds (the 1994 issue). City lends 
the proceeds of the 1994 issue to Developer. To evidence Developer's 
obligation to repay that loan, Developer, as obligor, issues a note to 
City (the City note). Bank agrees to provide Developer with a direct-pay 
letter of credit pursuant to which Bank will make all payments to the 
trustee for the 1994 issue necessary to meet Developer's obligations 
under the City note. Developer pays Bank a fee for the issuance of the 
letter of credit and issues a note to Bank (the Bank note). The Bank 
note is secured by a mortgage on the housing project and is guaranteed 
by FHA. The Bank note and the 1994 issue have different prepayment 
terms. The City does not reasonably expect to treat prepayments of the 
Bank note as gross proceeds of the 1994 issue. At the same time or 
pursuant to a series of related transactions, Bank sells the Bank note 
to Investor for $9.5 million. Bank invests these monies together with 
its other funds. In substance, the transaction is a loan by City to 
Bank, under which Bank enters into a series of transactions that, in 
effect, result in Bank retaining $9.5 million in amounts treated as 
proceeds of the 1994 issue. Those amounts are invested in materially 
higher yielding investments that provide funds sufficient to equal or 
exceed the Bank's liability under the letter of credit. Alternatively, 
the letter of credit is investment property in a sinking fund for the 
1994 issue provided by Developer, a substantial beneficiary of the 
financing. Because, in substance, Developer acquires the $10 million 
principal amount letter of credit for a fair market value purchase price 
of $9.5 million, the letter of credit is a materially higher yielding 
investment. Neither result would change if Developer's obligation under 
the Bank note is contingent on Bank performing its obligation under the 
letter of credit. Each characterization causes the bonds to be arbitrage 
bonds.
    Example 2. Bonds outstanding longer than necessary for yield-
blending device. (i) Longer bond maturity to create sinking fund. In 
1994, Authority issues an advance refunding issue (the refunding issue) 
to refund a 1982 prior issue (the prior issue). Under current market 
conditions, Authority will have to invest the refunding escrow at a 
yield significantly below the yield on the refunding issue. Authority 
issues its refunding issue with a longer weighted average maturity than 
otherwise necessary primarily for the purpose of creating a sinking fund 
for the refunding issue that will be invested in a guaranteed investment 
contract. The weighted average maturity of the refunding issue is less 
than 120 percent of the remaining average economic life of the 
facilities financed with the proceeds of the prior issue. The guaranteed 
investment contract has a yield that is higher than the yield on the 
refunding issue. The yield on the refunding escrow blended with the 
yield on the guaranteed investment contract does not exceed the yield on 
the issue. The refunding issue uses an abusive arbitrage device and the 
bonds of the issue are arbitrage bonds under section 148(a).
    (ii) Refunding of noncallable bonds. The facts are the same as in 
paragraph (i) of this Example 2 except that instead of structuring the 
refunding issue to enable it to take advantage of sinking fund 
investments, Authority will also refund other long-term, non-callable 
bonds in the same refunding issue. There are no savings attributable to 
the refunding of the non-callable bonds (e.g., a low-to-high refunding). 
The Authority invests the portion of the proceeds of the refunding issue 
allocable to the refunding of the non-callable bonds in the refunding 
escrow at a yield that is higher than the yield on the refunding issue, 
based on the relatively long escrow period for this portion of the 
refunding. The Authority invests the other portion of the proceeds of 
the refunding issue in the refunding escrow at a yield lower than the 
yield on the refunding issue. The blended yield on all the investments 
in the refunding escrow for the prior issues does not exceed the yield 
on the refunding issue. The portion of the refunding issue used to 
refund the noncallable bonds, however, was not otherwise necessary and 
was issued primarily to exploit the difference between taxable and tax-
exempt rates for that long portion of the refunding escrow to minimize 
the effect of lower yielding investments in the other portion of the 
escrow. The refunding issue uses an abusive arbitrage device and the 
bonds of the issue are arbitrage bonds.
    (iii) Governmental purpose. In paragraphs (i) and (ii) of this 
Example 2, the existence of a governmental purpose for the described 
financing structures would not change the conclusions unless Authority 
clearly established that the primary purpose for the use of the 
particular structure was a bona fide

[[Page 702]]

governmental purpose. The fact that each financing structure had the 
effect of eliminating significant amounts of negative arbitrage is 
strong evidence of a primary purpose that is not a bona fide 
governmental purpose. Moreover, in paragraph (i) of this Example 2, the 
structure of the refunding issue coupled with the acquisition of the 
guaranteed investment contract to lock in the investment yield 
associated with the structure is strong evidence of a primary purpose 
that is not a bona fide governmental purpose.
    Example 3. Window refunding. (i) Authority issues its 1994 refunding 
issue to refund a portion of the principal and interest on its 
outstanding 1985 issue. The 1994 refunding issue is structured using 
zero-coupon bonds that pay no interest or principal for the 5-year 
period following the issue date. The proceeds of the 1994 refunding 
issue are deposited in a refunding escrow to be used to pay only the 
interest requirements of the refunded portion of the 1985 issue. 
Authority enters into a guaranteed investment contract with a financial 
institution, G, under which G agrees to provide a guaranteed yield on 
revenues invested by Authority during the 5-year period following the 
issue date. The guaranteed investment contract has a yield that is no 
higher than the yield on the refunding issue. The revenues to be 
invested under this guaranteed investment contract consist of the 
amounts that Authority otherwise would have used to pay principal and 
interest on the 1994 refunding issue. The guaranteed investment contract 
is structured to generate receipts at times and in amounts sufficient to 
pay the principal and redemption requirements of the refunded portion of 
the 1985 issue. A principal purpose of these transactions is to avoid 
transferred proceeds. Authority will continue to invest the unspent 
proceeds of the 1985 issue that are on deposit in a refunding escrow for 
its 1982 issue at a yield equal to the yield on the 1985 issue and will 
not otherwise treat those unspent proceeds as transferred proceeds of 
the 1994 refunding issue. The 1994 refunding issue is an issue of 
arbitrage bonds since those bonds involve a transaction or series of 
transactions that overburdens the market by leaving bonds outstanding 
longer than is necessary to obtain a material financial advantage based 
on arbitrage. Specifically, Authority has structured the 1994 refunding 
issue to make available for the refunding of the 1985 issue replacement 
proceeds rather than proceeds so that the unspent proceeds of the 1985 
issue will not become transferred proceeds of the 1994 refunding issue.
    (ii) The result would be the same in each of the following 
circumstances:
    (A) The facts are the same as in paragraph (i) of this Example 3 
except that Authority does not enter into the guaranteed investment 
contract but instead, as of the issue date of the 1994 refunding issue, 
reasonably expects that the released revenues will be available for 
investment until used to pay principal and interest on the 1985 issue.
    (B) The facts are the same as in paragraph (i) of this Example 3 
except that there are no unspent proceeds of the 1985 issue and 
Authority invests the released revenues at a yield materially higher 
than the yield on the 1994 issue.
    (C) The facts are the same as in paragraph (i) of this Example 3 
except that Authority uses the proceeds of the 1994 issue for capital 
projects instead of to refund a portion of the 1985 issue.
    Example 4. Sale of conduit loan. On January 1, 1994, Authority 
issues a conduit financing issue (the 1994 conduit financing issue) and 
uses the proceeds to purchase from City, an unrelated party, a tax-
exempt bond of City (the City note). The proceeds of the 1994 conduit 
financing issue are to be used to advance refund a prior conduit 
financing issue that was issued in 1988 and used to make a loan to City. 
The 1994 conduit financing issue and the City note each have a yield of 
8 percent on January 1, 1994. On June 30, 1996, interest rates have 
decreased and Authority sells the City note to D, a person unrelated to 
either City or Authority. Based on the sale price of the City note and 
treating June 30, 1996 as the issue date of the City note, the City note 
has a 6 percent yield. Authority deposits the proceeds of the sale of 
the City note into an escrow to redeem the bonds of the 1994 conduit 
financing issue on January 1, 2001. The escrow is invested in nonpurpose 
investments having a yield of 8 percent. For purposes of section 149(d), 
City and Authority are related parties and, therefore, the issue date of 
the City note is treated as being June 30, 1996. Thus, the City note is 
an advance refunding of Authority's 1994 conduit financing issue. 
Interest on the City note is not exempt from Federal income tax from the 
date it is sold to D under section 149(d), because, by investing the 
escrow investments at a yield of 8 percent instead of a yield not 
materially higher than 6 percent, the sale of the City note employs a 
device to obtain a material financial advantage, based on arbitrage, 
apart from the savings attributable to lower interest rates. In 
addition, the City note is not a tax-exempt bond because the note is the 
second advance refunding of the original bond under section 149(d)(3). 
The City note also employs an abusive arbitrage device and is an 
arbitrage bond under section 148.
    Example 5. Re-refunding. (i) On January 1, 1984, City issues a tax-
exempt issue (the 1984 issue) to finance the cost of constructing a 
prison. The 1984 issue has a 7 percent yield and a 30-year maturity. The 
1984 issue is callable at any time on or after January 1, 1994. On 
January 1, 1990, City issues a refunding issue (the 1990 issue) to 
advance refund the 1984 issue. The 1990 issue has an 8 percent

[[Page 703]]

yield and a 30-year maturity. The 1990 issue is callable at any time on 
or after January 1, 2000. The proceeds of the 1990 issue are invested at 
an 8 percent yield in a refunding escrow for the 1984 issue (the 
original 1984 escrow) in a manner sufficient to pay debt service on the 
1984 issue until maturity (i.e., an escrow to maturity). On January 1, 
1994, City issues a refunding issue (the 1994 issue). The 1994 issue has 
a 6 percent yield and a 30-year maturity. City does not invest the 
proceeds of the 1994 issue in a refunding escrow for the 1990 issue in a 
manner sufficient to pay a portion of the debt service until, and redeem 
a portion of that issue on, January 1, 2000. Instead, City invests those 
proceeds at a 6 percent yield in a new refunding escrow for a portion of 
the 1984 issue (the new 1984 escrow) in a manner sufficient to pay debt 
service on a portion of the 1984 issue until maturity. City also 
liquidates the investments allocable to the proceeds of the 1990 issue 
held in the original 1984 escrow and reinvests those proceeds in an 
escrow to pay a portion of the debt service on the 1990 issue itself 
until, and redeem a portion of that issue on, January 1, 2000 (the 1990 
escrow). The 1994 bonds are arbitrage bonds and employ an abusive device 
under section 149(d)(4). Although, in form, the proceeds of the 1994 
issue are used to pay principal on the 1984 issue, this accounting for 
the use of the proceeds of the 1994 issue is an unreasonable, 
inconsistent accounting method under Sec. 1.148-6(a). Moreover, since 
the proceeds of the 1990 issue were set aside in an escrow to be used to 
retire the 1984 issue, the use of proceeds of the 1994 issue for that 
same purpose involves a replacement of funds invested in higher yielding 
investments under section 148(a)(2). Thus, using a reasonable, 
consistent accounting method and giving effect to the substance of the 
transaction, the proceeds of the 1994 issue are treated as used to 
refund the 1990 issue and are allocable to the 1990 escrow. The proceeds 
of the 1990 issue are treated as used to refund the 1984 issue and are 
allocable to the investments in the new 1984 escrow. The proceeds of the 
1990 issue allocable to the nonpurpose investments in the new 1984 
escrow become transferred proceeds of the 1994 issue as principal is 
paid on the 1990 issue from amounts on deposit in the 1990 escrow. As a 
result, the yield on nonpurpose investments allocable to the 1994 issue 
is materially higher than the yield on the 1994 issue, causing the bonds 
of the 1994 issue to be arbitrage bonds. In addition, the transaction 
employs a device under section 149(d)(4) to obtain a material financial 
advantage based on arbitrage, other than savings attributable to lower 
interest rates.
    (ii) The following changes in the facts do not affect the conclusion 
that the 1994 issue consists of arbitrage bonds--
    (1) The 1990 issue is a taxable issue;
    (2) The original 1984 escrow is used to pay the 1994 issue (rather 
than the 1990 issue); or
    (3) The 1994 issue is used to retire the 1984 issue within 90 days 
of January 1, 1994.

    (e) Authority of the Commissioner to clearly reflect the economic 
substance of a transaction. If an issuer enters into a transaction for a 
principal purpose of obtaining a material financial advantage based on 
the difference between tax-exempt and taxable interest rates in a manner 
that is inconsistent with the purposes of section 148, the Commissioner 
may exercise the Commissioner's discretion to depart from the rules of 
Sec. 1.148-1 through Sec. 1.148-11 as necessary to clearly reflect the 
economic substance of the transaction. For this purpose, the 
Commissioner may recompute yield on an issue or on investments, 
reallocate payments and receipts on investments, recompute the rebate 
amount on an issue, treat a hedge as either a qualified hedge or not a 
qualified hedge, or otherwise adjust any item whatsoever bearing upon 
the investments and expenditures of gross proceeds of an issue. For 
example, if the amount paid for a hedge is specifically based on the 
amount of arbitrage earned or expected to be earned on the hedged bonds, 
a principal purpose of entering into the contract is to obtain a 
material financial advantage based on the difference between tax-exempt 
and taxable interest rates in a manner that is inconsistent with the 
purposes of section 148.
    (f) Authority of the Commissioner to require an earlier date for 
payment of rebate. If the Commissioner determines that an issue is 
likely to fail to meet the requirements of Sec. 1.148-3 and that a 
failure to serve a notice of demand for payment on the issuer will 
jeopardize the assessment or collection of tax on interest paid or to be 
paid on the issue, the date that the Commissioner serves notice on the 
issuer is treated as a required computation date for payment of rebate 
for that issue.
    (g) Authority of the Commissioner to waive regulatory limitations. 
Notwithstanding any specific provision in Secs. 1.148-1 through 1.148-
11, the Commissioner may prescribe extensions of temporary periods, 
larger reasonably required reserve or replacement funds, or consequences 
of failures or remedial

[[Page 704]]

action under section 148 in lieu of or in addition to other consequences 
of those failures, or take other action, if the Commissioner finds that 
good faith or other similar circumstances so warrant, consistent with 
the purposes of section 148.
