 OPINION
 TASHIMA, Circuit Judge:
 Appellants are motor carriers and their officers
who were
 prosecuted for antitrust violations but were
ultimately exoner-
 ated, because their conduct was found to
be covered by an
                               
1164
 antitrust immunity provision of the Shipping
Act of 1984, 46
 U.S.C. app. SS 1701--1719. Appellants then
moved for attor-
 ney's fees and costs under the Hyde Amendment.
Pub. L. No.
 105-119, Title VI, S 617, 111 Stat. 2519
(1997), reprinted in
 18 U.S.C. S 3006A (historical and statutory
notes). The dis-
 trict court denied the motion. We have jurisdiction
of this
 timely appeal under 28 U.S.C. S 1291, and
we affirm.
 I. BACKGROUND
 A. Factual Background and Prior Proceedings 
 When American military personnel serving abroad
are relo-
 cated to the United States, the government
makes arrange-
 ments for the shipping of their belongings.
The government
 contracts for "through transportation," which
means that the
 belongings are transported under a single
bill of lading from
 their point of origin to their final destination,
although trans-
 portation along different segments of the
route is often pro-
 vided by different carriers using different
modes of carriage.
 Appellants are engaged in the business of
motor transporta-
 tion within the Philippines. As part of the
through transporta-
 tion of the belongings of American military
personnel
 returning from the Philippines, Appellants
trucked the belong-
 ings from Subic Bay Naval Base and Clark
Air Force Base to
 a Philippine seaport, where the belongings
were loaded onto
 vessels bound for the United States. Appellants
were indicted
 on September 9, 1992, for violating Section
1 of the Sherman
 Act, 15 U.S.C. S 1, by conspiring to fix
prices.
 Appellant Tucor Industries, Inc. is a Philippine
corporation.
 Pursuant to a plea agreement, Tucor pleaded
guilty to the
 Sherman Act charge and was fined $121,800.
Judgment was
 entered on June 22, 1993. In 1997, Tucor
filed a petition for
 a writ of error coram nobis, seeking to have
the judgment
 vacated.
                               
1165
 Appellants Luzon Moving and Storage Corp.
and
 Philippine-American Moving and Storage Corp.
(PAMSC)
 are Philippine corporations. Appellants George
Schulze, Sr.,
 and George Schulze, Jr., are officers and
shareholders of
 Luzon and PAMSC. These Appellants never appeared
before
 the district court for arraignment, but in
1997 they made a
 special appearance in order to move to dismiss
the indictment.
 The district court granted the petition for
writ of error
 coram nobis, vacated the judgment against
Tucor, and granted
 the motion to dismiss the indictment of Luzon,
PAMSC, and
 the Schulzes. United States v. Tucor Int'l,
Inc. , 35 F. Supp. 2d
 1172, 1189 (N.D. Cal. 1998) (Tucor I), aff'd,
189 F.3d 834
 (9th Cir. 1999). The court held that because
Appellants pro-
 vided ground transportation solely within
the Philippines,
 those activities were immunized against antitrust
liability by
 Section 7(a)(4) of the Shipping Act of 1984,
46 U.S.C. app.
 S 1706(a)(4) (providing that "[t]he antitrust
laws do not apply
 to . . . any agreement or activity concerning
the foreign inland
 segment of through transportation that is
part of transportation
 provided in a United States import or export
trade"). Id. at
 1182--83. We affirmed. United States v. Tucor
Int'l Inc., 189
 F.3d 834, 838 (9th Cir. 1999) (Tucor II).
 Both in the district court and on appeal,
the government
 argued unsuccessfully that the Shipping Act's
antitrust immu-
 nities did not apply to Appellants because
the immunities
 should be limited to entities that are "ocean
common carri-
 ers," as that term is defined in Section
3 of the Shipping Act,
 46 U.S.C. app. S 1702(6), (16). Appellants
are concededly not
 ocean common carriers, but both Tucor I and
Tucor II held
 that the relevant exemption is not limited
to ocean common
 carriers.
 Appellants next brought a motion in the district
court for
 attorney's fees and costs under the Hyde
Amendment, which
 provides that a court may award fees and
costs to a prevailing
 criminal defendant if the court "finds that
the position of the
                               
1166
 United States was vexatious, frivolous, or
in bad faith, unless
 the court finds that special circumstances
make such an award
 unjust." 18 U.S.C. S 3006A (historical and
statutory notes).
 The district court denied the motion, finding
both that the
 government had a good-faith but erroneous
belief in the cor-
 rectness of its interpretation of the Shipping
Act and that the
 government's interpretation was not so clearly
contrary to the
 statutory language as to render the prosecution
vexatious or
 frivolous. This timely appeal followed.
 B. The Greek Case
 Some of Appellants' arguments are based on
what they
 refer to as "the Greek case," a separate
antitrust investigation
 that was taking place at the same time that
Appellants were
 being prosecuted. When Hellenikon Air Force
Base in Greece
 was closed in 1990, the government arranged
for through
 transportation of the belongings of returning
Hellenikon per-
 sonnel, just as it did for personnel returning
from the Philip-
 pines. The Department of Justice conducted
an investigation
 of potential antitrust violations in Greece
that paralleled those
 alleged in Appellants' case--agreements among
carriers han-
 dling the foreign inland segment of through
transportation. On
 February 9, 1993, Warren L. Dean, Jr., an
attorney for one of
 the Greek inland carriers under investigation,
met with coun-
 sel for the government and argued that Section
7 immunized
 his client's activities against antitrust
liability. Dean provided
 the government with a written analysis to
the same effect on
 February 17, 1993.
 The Department of Justice was thus made aware
of the rele-
 vance of the Shipping Act's antitrust exemptions
four months
 before Tucor's plea hearing, but it did not
disclose the poten-
 tial applicability of those provisions to
the district court or to
 Tucor. On December 1, 1993, the government
decided not to
 prosecute the Greek carriers. Appellants
infer from this that
 the government agreed with Dean's interpretation
of the Ship-
 ping Act, recognized that the Greek carriers
were immune,
                               
1167
 and thus also recognized that Appellants
were immune. In
 Tucor I, the district court largely rejected
these arguments,
 finding (1) that "the government had not
concluded at the
 time of Tucor's plea that Section 7(a)(4)
immunized Tucor
 from prosecution," (2) that Tucor had failed
to prove selective
 prosecution, but (3) that the government
had probably vio-
 lated its duty of candor to the court by
failing to bring the
 immunity provisions to the court's attention.
Tucor I, 35 F.
 Supp. 2d at 1188.
 II. STANDARD OF REVIEW
 A district court's denial of a motion for
attorney's fees
 under the Hyde Amendment is reviewed for
abuse of discre-
 tion. United States v. Lindberg, 220 F.3d
1120, 1124 (9th Cir.
 2000). Under that standard, this court cannot
reverse unless it
 has a definite and firm conviction that the
district court com-
 mitted a clear error of judgment. Id. The
district court abuses
 its discretion when it makes an error of
law, Koon v. United
 States, 518 U.S. 81, 100 (1996), or bases
its conclusion on a
 clearly erroneous finding of fact, Paradis
v. Arave, 130 F.3d
 385, 390 (9th Cir. 1997).
 III. DISCUSSION
 To a large extent, Appellants' arguments hinge
on the rea-
 sonableness of the government's now-discredited
theory that
 the Shipping Act's antitrust immunity provisions
do not apply
 to Appellants. Appellants also contend that
that theory contra-
 dicts the position successfully advocated
by the government
 in an earlier case, Transpacific Westbound
Rate Agreement v.
 Federal Maritime Commission, 951 F.2d 950
(9th Cir. 1991),
 thus conflicting with both binding precedent
and the govern-
 ment's prior interpretation of the Act. We
analyze these broad
 issues first, before turning to Appellants'
other, narrower
 arguments.
                               
1168
 A. The Shipping Act and Appellee's Interpretation
of
 the Antitrust Immunities
 Section 3 of the Shipping Act defines "common
carrier" as
 follows:
       "[C]ommon carrier"
means a person holding itself
       out to the
general public to provide transportation by
       water of passengers
or cargo between the United
       States and
a foreign country for compensation that--
       (A) assumes
responsibility for the transpor-
       tation from
the port or point of receipt to
       the port or
point of destination, and
       (B) utilizes,
for all or part of that transpor-
       tation, a
vessel operating on the high seas
       or the Great
Lakes between a port in the
       United States
and a port in a foreign coun-
       try . . .
.
 46 U.S.C. app. S 1702(6). "Person" is defined
to include "in-
 dividuals, corporations, partnerships," and
other associations
 recognized by law. Id. S 1702(18). An "ocean
common carri-
 er" is defined as a "vessel-operating common
carrier." Id.
 S 1702(16).
 Section 4 of the Act, entitled "Agreements
within scope of
 chapter," provides that the Act applies to
"agreements by or
 among ocean common carriers" regarding certain
specified
 activities, and also to a narrower range
of "agreements among
 marine terminal operators." Id. S 1703(a),
(b). Section 5 then
 provides that a true copy of any agreement
covered by Section
 4 must be filed with the Federal Maritime
Commission
 (FMC), but Section 5 also creates an exception
to the filing
 requirement for "agreements related to transportation
to be
 performed within or between foreign countries
and agree-
                               
1169
 ments among common carriers to establish,
operate, or main-
 tain a marine terminal in the United States."
Id. S 1704(a).
 Section 7 then lists certain agreements and
activities to
 which "[t]he antitrust laws do not apply.
" Id. S 1706(a). In
 particular, Sections 7(a)(1) and 7(a)(2)
essentially immunize
 all agreements filed under Section 5. Id.S
1706(a)(1)--(2).
 Section 7(a)(4), which in Tucor II was held
to apply to Appel-
 lants' conduct, immunizes "any agreement
or activity con-
 cerning the foreign inland segment of through
transportation
 that is part of transportation provided in
a United States
 import or export trade." Id. S 1706(a)(4).
Section 7(a)(4) does
 not make any explicit reference to common
carriers or to
 ocean common carriers. Also, it deals only
with foreign-to-
 foreign transportation ("the foreign inland
segment of through
 transportation"), whereas the Act defines
"common carrier" in
 terms of transportation between the United
States and a for-
 eign country.
 These considerations tend to make the government's
posi-
 tion in Tucor I and Tucor II, namely, that
the grant of immu-
 nity in Section 7(a)(4) applies only to ocean
common carriers,
 look unreasonable. But the government's position
gains at
 least some measure of reasonableness when
it is understood
 in terms of the following general underlying
premise: Accord-
 ing to the government, the antitrust immunities
granted by the
 Shipping Act were intended to be limited
to the entities, activ-
 ities, and agreements that are brought within
the FMC's regu-
 latory jurisdiction by the Act. In essence,
the point of Section
 7(a)(4), according to the government, is
to immunize agree-
 ments (and consequent activities) that are
within the scope of
 the Act under Section 4 but that fall within
Section 5(a)'s
 exception for foreign-to-foreign agreements
among ocean
 common carriers. Because such agreements
are not required
 to be filed under Section 5(a), they are
not immunized by Sec-
 tions 7(a)(1) and 7(a)(2). The purpose of
Section 7(a)(4),
 according to the government, is to fill part
of that gap, but as
                               
1170
 a result it is limited to agreements (and
consequent activities)
 among ocean common carriers.
 [1] These considerations do not, of course,
entirely resolve
 the tensions between the statutory text and
the position that
 the government advocated, and its interpretation
of Section
 7(a)(4) was ultimately rejected by this court
in Tucor II. But
 placed in the context of the government's
understanding of
 the interplay between the regulatory scope
of the Shipping
 Act and the antitrust immunities that the
Act provides, the
 government's interpretation of Section 7(a)(4)
does not seem
 nearly as contrary to the plain meaning of
the statute as it
 might appear on first look. Other than repeatedly
asserting
 that the government's position is obviously
at odds with the
 statutory text, Appellants have presented
no arguments to
 show that the district court abused its discretion
in finding that
 that position "was not so obviously wrong
as to be frivolous."
 B. Transpacific
 In 1987, the FMC proposed a rule that would
have allowed
 voluntary filing of agreements that are not
subject to the filing
 requirement of Section 5(a). 52 Fed. Reg.
46,501 (proposed
 Dec. 8, 1987). Under the proposed rule, such
voluntarily filed
 agreements would thereby be brought within
the Section
 7(a)(1)--(2) antitrust immunity for filed
agreements. Id.
 After receiving comments from various parties,
including
 vigorous opposition from the Department of
Justice, the FMC
 withdrew the proposed rule. The FMC reasoned
that an entity
 is a common carrier only insofar as it provides
transportation
 services between the United States and a
foreign country--
 when such a carrier provides foreign-to-foreign
transportation
 services, it does not, as regards those services,
qualify as a
 common carrier under the Act. Thus, agreements
concerning
 foreign-to-foreign transportation are not
agreements within
 the scope of the Act under Section 4, because
they are not
 agreements among common carriers (i.e., for
purposes of
                               
1171
 those agreements, the parties are not acting
as common carri-
 ers). See Transpacific, 951 F.2d at 953.
On this basis, the
 FMC issued an order in which it held that
it had jurisdiction
 only over agreements concerning transportation
between the
 United States and a foreign country. The
order rejected the
 concept of voluntary filing and stated that
an agreement that
 concerned both regulated and unregulated
activity (a "mixed
 agreement") could no longer be filed in its
entirety. Thus,
 only those portions of a mixed agreement
that concerned
 United States--to-foreign transportation
could be filed and
 thereby brought within the antitrust immunity
provisions of
 Section 7(a)(1)--(2). See Transpacific, 951
F.2d at 952.
 The Transpacific Westbound Rate Agreement,
an associa-
 tion of ocean common carriers, challenged
the FMC's order.
 Transpacific argued that the FMC did have
jurisdiction over
 the foreign-to-foreign portions of mixed
agreements and, in
 the alternative, defended the concept of
voluntary filing.
 Transpacific, 951 F.2d at 952. The Department
of Justice and
 the FMC jointly filed a brief in support
of the order. This
 court found no error in the FMC's interpretation
of the Ship-
 ping Act and upheld the FMC's order. Transpacific,
951 F.2d
 at 957.
 Appellants now argue that the government's
position in
 Transpacific conflicts with the government's
position in the
 Tucor prosecution, for the following reasons:
In Transpacific,
 the government defended the FMC's position
that an entity
 qualifies as a common carrier only insofar
as it engages in
 United States--to-foreign transportation.
Section 7(a)(4), the
 antitrust immunity provision at issue in
the Tucor prosecution,
 concerns only foreign-to-foreign transportation.
Therefore,
 under the reasoning successfully advocated
by the govern-
 ment in Transpacific, Section 7(a)(4) cannot
apply to com-
 mon carriers. But the government contended
throughout the
 Tucor prosecution that Section 7(a)(4) applies
to common car-
 riers and to no one else.
                               
1172
 This argument amounts to nothing more than
a terminologi-
 cal confusion. The government's position
in the Tucor prose-
 cution was that the immunity provisions in
Section 7 apply
 only to entities that engage in some common
carrier activity,
 that is, to entities that do qualify as common
carriers for at
 least some of the transportation services
that they provide. On
 this reading, Section 7(a)(4) immunizes any
agreements
 among such entities that concern foreign-to-foreign
transpor-
 tation. It is true that, under the reasoning
of Transpacific,
 those entities are not common carriers for
purposes of those
 agreements. But the government's position
in the Tucor pros-
 ecution was simply that those entities would
not be eligible
 for the Section 7(a)(4) immunity if they
were not common
 carriers for purposes of some other transportation
services that
 they provide.
 [2] There is no substantive conflict between
that position
 and the position successfully advocated by
the government in
 Transpacific. At most, Appellants' argument
shows that the
 government should have used the term "common
carrier"
 more carefully in describing its position
in the Tucor prosecu-
 tion. Instead of saying that Section 7(a)(4)
applies only to
 ocean common carriers, the government should
have said that
 Section 7(a)(4) applies only to entities
that engage in some
 activity that qualifies them as ocean common
carriers with
 respect to that activity, although the activity
that makes them
 ocean common carriers is not itself immunized
by Section
 7(a)(4).
 Moreover, some of the reasoning of Transpacific 
actually
 supports the underlying premise of the government's
position
 in the Tucor prosecution, namely, that the
scope of the anti-
 trust immunities granted by the Act should
be tied to the regu-
 latory jurisdiction conferred on the FMC
by the Act. In
 Transpacific, we reasoned that because the
Act describes the
 FMC's regulatory powers as limited to common
carriers, it is
 unlikely that the Act was meant to confer
antitrust immunity
 on any entities that are not common carriers.
See 951 F.2d at
                               
1173
 954. "It does not seem logical that Congress
intended to con-
 fer antitrust immunity on parties largely
outside of the regula-
 tory power of the FMC . . . ." Id. In this
way, the reasoning
 of Transpacific actually embraces, rather
than conflicts with,
 the position advocated by the government
in the Tucor prose-
 cution. Transpacific thus makes the government's
position in
 the Tucor prosecution look more plausible
than it otherwise
 would; it does not undermine it.
 For all of these reasons, we reject Appellants'
argument
 that the government's position in the Tucor
prosecution was
 contrary to the position successfully advocated
by the govern-
 ment in Transpacific.
 C. Appellants' Remaining Arguments
 1. Failure to Apply the Terms of the Hyde
Amend-
 ment Disjunctively
 Under the Hyde Amendment, a court may award
fees and
 costs to a prevailing criminal defendant
if the court "finds that
 the position of the United States was vexatious,
frivolous, or
 in bad faith, unless the court finds that
special circumstances
 make such an award unjust." 18 U.S.C. S 3006A
(historical
 and statutory notes). The plain meaning of
the text indicates
 that the test is disjunctive--satisfaction
of any one of the three
 criteria (vexatiousness, frivolousness, or
bad faith) should suf-
 fice by itself to justify an award. Appellants
argue that the dis-
 trict court failed to apply the test in this
way, instead holding
 Appellants to a single "generalized burden
of proof."
 [3] The argument is without merit. The district
court
 engaged in a detailed analysis of the text
of the Hyde Amend-
 ment, including separate definitions of the
terms "vexatious,"
 "frivolous," and "bad faith." The district
court stated that it
 had already found, in Tucor I, that "the
government honestly
 believed at the plea hearing that the conduct
in the Indictment
 was prohibited by law and did not fall within
the immunity
                               
1174
 clauses of the Shipping Act." That factual
finding negates bad
 faith. The district court further concluded
that "the legal posi-
 tion taken by the government was a defensible
one in a first
 impression circumstance." That conclusion
is sufficient to
 establish that the prosecution was neither
vexatious nor frivo-
 lous, on any understanding of those terms.1
For all of these
 reasons, Appellants' argument fails.
 2. Failure to Treat the Statute as "Binding
Precedent"
 [4] Appellants argue that the district court
erred by "requir-
 [ing] that the prosecution be foreclosed
by binding judge-
 made law," rather than treating the "clear
and unambiguous
 statutory language" of the Shipping Act as
"binding prece-
 dent." The argument is without merit. As
the district court
 explicitly stated, "The Court is satisfied
that the legal position
 taken by the government in this case was
not foreclosed by
 binding precedent and that it was not so
obviously wrong as
 to be frivolous." (emphasis added) (citation
omitted). The
 emphasized portion indicates that the court
did consider the
 reasonableness of the government's position
independently of
 the absence of contrary case law. The district
court did not
 ignore the statutory language--it just found
the statute to be
 somewhat less clear and unambiguous than
Appellants claim
 it is. Analyses of both the statute and the
government's inter-
 pretation of it indicate that the district
court did not abuse its
 discretion in so finding. See Part III.A,
supra.
 _________________________________________________________________
 1 There is no Ninth Circuit case law on the
Hyde Amendment that spells
 out precisely what the terms "vexatious,""frivolous,"
and "bad faith"
 mean. The court in Lindberg noted this lacuna
but saw no need to fill it,
 because on any plausible interpretation of
those terms, the district court in
 that case had not abused its discretion.
Lindberg, 220 F.3d at 1125 (citing
 cases from the Fourth and Eleventh Circuits
that have analyzed the terms,
 but declining to reach the issue). The instant
case is similar.
                               
1175
 3. The Government's Allegedly Unethical Conduct
 Appellants argue (1) that the government learned
of the
 applicability of Section 7(a)(4) through
its investigation of the
 Greek case, (2) that the government intentionally
violated its
 ethical duties by withholding this exculpatory
information
 from both Appellants and the district court,
and (3) that the
 district court erred by failing to find that
such intentional
 unethical behavior was vexatious, frivolous,
or in bad faith.
 We are unpersuaded by Appellants' argument.
 [5] The district court found in Tucor I and
reaffirmed in
 this case that "the government honestly believed
at the plea
 hearing that the conduct in the Indictment
was prohibited by
 law and did not fall within the immunity
clauses of the Ship-
 ping Act." (citing Tucor I). In Tucor I,
the district court based
 this finding of fact on the declaration of
a Department of Jus-
 tice attorney who was involved in both the
Greek case and the
 Tucor prosecution. See Tucor I, 35 F. Supp.
2d at 1187--88.
 The district court was fully aware of the
circumstances of the
 Greek case. See id. at 1187. The court was
under no obliga-
 tion to conclude that the government's reason
for not prose-
 cuting the Greek carriers was that the government
believed
 that Section 7 barred such prosecution, and
the court explic-
 itly declined to draw any such inference.
Id.  at 1188 ("Any
 number of factors could have been involved
in the govern-
 ment's decision not to prosecute the Greek
companies that
 were under investigation."). In effect, Appellants'
argument
 merely repeats the facts of the Greek case
and asks this court
 to make factual findings contrary to those
made by the district
 court. Appellants have given us no reason
to conclude that the
 district court's findings were clearly erroneous.
 [6] Because the government honestly believed
that the Sec-
 tion 7 immunities did not apply in the Tucor
prosecution, the
 decision to prosecute was not in bad faith.
In addition, Appel-
 lants have failed to explain how the government's
failure to
 disclose legal authority that the government
believed to be
                               
1176
 irrelevant could make the decision to prosecute
vexatious or
 frivolous.2 Appellants have not shown that
the government's
 interpretation of the Shipping Act was so
unreasonable as to
 deprive the government of probable cause
to prosecute. Nor
 could a finding of vexatiousness or frivolousness
be based on
 the claim that this court had already ruled
against the govern-
 ment's position, because the result and the
reasoning of
 Transpacific were in fact consistent with,
and at least partially
 supportive of, the government's position
in the Tucor prose-
 cution.
 Nonetheless, there remains the district court's
suggestion in
 Tucor I that the government's failure to
inform the court
 about the Section 7 immunities might constitute
an ethical
 violation. See Tucor I, 35 F. Supp. 2d at
1188 (noting that the
 government's failure to inform the court
about the immunities
 "represents a far too restrictive view of
prosecutorial obliga-
 tions"). But in ruling on the Hyde Amendment
motion, the
 district court explained that its remarks
in Tucor I were meant
 only "as an assessment of faulty judgment
by the govern-
 ment," not as an indication that the government's
conduct
 "was intended to defraud the Court." On any
plausible inter-
 pretation of the Hyde Amendment standard,
mere "faulty
 judgment" is not vexatious, frivolous, or
in bad faith. Appel-
 lants have not shown that the district court's
finding of "faulty
 judgment," as opposed to intentional fraud,
was an abuse of
 discretion.
 _________________________________________________________________
 2 Appellants attempt to characterize the
government's conduct as akin to
 a violation of Brady v. Maryland, 373 U.S.
83 (1963), but this argument
 is without merit. Brady held that prosecutors
have a constitutional duty to
 disclose exculpatory evidence to criminal
defendants. See id. at 87. Appel-
 lants have cited no authority for the proposition
that prosecutors are under
 any duty, legal or ethical, to disclose relevant
legal authority to criminal
 defendants, and we are aware of none. Prosecutors,
like all lawyers, have
 an ethical duty to disclose relevant legal
authority to the court, but that has
 nothing to do with Brady. See, e.g., Model
Rules of Prof'l Conduct R. 3.3
 (1995).

 4. Different Interpretations of the Indictment
 In opposing Appellants' motion for fees and
costs before
 the district court, the government argued
that its interpretation
 of the indictment was broader than the district
court's and the
 Ninth Circuit's, and that the government
consequently
 believed that the indictment related in part
to conduct that was
 not considered by the courts and that was
clearly not protected
 by the Section 7 immunity provisions. The
government
 offered this argument to negate bad faith,
and the district
 court appears to have approved of the argument
to some
 extent. Appellants argue that this was error.
We need not,
 however, and do not decide the merits of
this contention.
 The government's argument regarding its interpretation
of
 the indictment related only to bad faith,
and that is how the
 district court treated it. But lack of bad
faith is already estab-
 lished by the district court's finding that
the government hon-
 estly believed that the Section 7 immunities
did not apply to
 Appellants. Appellants' attack on the government's
other
 argument regarding bad faith does not undermine
that conclu-
 sion.
 IV. CONCLUSION
 For the foregoing reasons, we conclude that
the district
 court did not abuse its discretion in finding
that the position
 of the United States was not vexatious, frivolous,
or in bad
 faith. The decision of the district court
is therefore
 AFFIRMED.
