OPINION
This appeal arises from a class member/objector’s challenge to the district court’s final approval of a settlement of the antitrust claims of a certified nationwide class of consumers of department store cosmetics. We must decide two questions.
First, as a matter of first impression, we must decide whether, or under what circumstances, appellate attorney’s fees are “costs on appeal” that a district court may require an appellant to secure in a bond ordered under Federal Rule of Appellate Procedure 7 (“Rule 7”). We conclude that a district court may require an appellant to secure appellate attorney’s fees in a Rule 7 bond, but only if an applicable fee-shifting statute includes them in its definition of recoverable costs, and only if the appellee is eligible to recover such fees. The fee-shifting provision in Section 4 of the Clayton Act, 15 U.S.C. § 15, includes attorney’s fees in its definition of costs recoverable by a prevailing plaintiff. However, this provision does not authorize taxing attorney’s fees against a class member/objector challenging a settlement in an antitrust *954 suit. Thеrefore, we hold that the district court erred by requiring security in the Rule 7 bond for attorney’s fees as costs taxable under Clayton Act Section 4.
We further conclude that a district court may not include in a Rule 7 bond appellate attorney’s fees that might be awarded by the court of appeals if that court holds that the appeal is frivolous under Federal Rule of Appellate Procedure 38 (“Rule 38”).
Second, we must decide whether Appellant’s appeal on the merits should be dismissed for failure to post the bond. In the circumstances of this case, we hold that it should not.
In a separate unpublished memorandum disposition, we reach the merits of the appeal and affirm the district court’s approval of the settlement.
I. Background
Appellant Kamela Wilkinson is one of a large number of consumers who bought cosmetics products manufactured and sold by Defendants-Appellees. In July 2003, Plaintiffs-Appellees commenced, on behalf of these consumers, a nationwide, settlement-only antitrust class action lawsuit in the federal district court for the Northern District of California. They alleged that Defendants-Appellees had violated the Sherman Act аnd California’s Cartwright and Unfair Competition Acts by “entering] into and engaging] in ... a contract, combination or conspiracy ... to fix, raise, and stabilize the prices of Department Store Cosmetics and to limit the supply of Department Store Cosmetics.” On March 30, 2005, the district court approved a settlement of all class claims. Wilkinson appealed from the final approval order on April 29, 2005.
In July 2005, Plaintiffs-Appellees sought an appeal bond of $12,833,501.80 under Rule 7. This amount included two times their estimate of anticipated (1) appellate costs, not including attorney’s fees, recoverable under Federal Rule of Appellate Procedure 39 (“Rule 39”) ($6,540.00), (2) appellate attorney’s fees ($300,000.00), (3) interest on the settlement’s $24 million attorney’s fees award ($178,457.68), and (4) damages resulting from delay ($5,931,-753.22). The district court ordered Wilkinson to post a bond in the amount of $42,000.00, representing an anticipated $2,000.00 in appellate costs taxable under Rule 39 and $40,000.00 in appellate attorney’s fees. The district court noted that a split in circuit authority exists regarding whether attorney’s fees are “costs on appeal” securable under Rule 7, and that this circuit had not yet addressed this issue. It сoncluded that the bond could cover appellate attorney’s fees because (1) the fee-shifting provision in Section 4 of the Clayton Act, 15 U.S.C. § 15, defines attorney’s fees as among the costs recoverable, and (2) “the Court of Appeals [was] likely to find that the instant appeal[] [was] frivolous.”
On August 19, 2005, Wilkinson tendered $2,000.00 to the district court clerk, which was rejected. Wilkinson then moved the district court to reduce the bond amount. After the district court denied her motion, she appealed from that order. On September 19, 2005, Plaintiffs-Appellees filed a motion asking us to dismiss Wilkinson’s appeаl of final approval of the settlement, based on her failure to pay the Rule 7 bond. A motions panel of this court denied the motion on December 12, 2005, with leave to Plaintiffs-Appellees to renew their request for dismissal in their answering brief, which they have done.
II. Discussion
Federal Rule of Appellate Procedure 7, derived from former Federal Rule of Civil Procedure 73(c), provides that “the district court may require an appellant to file a bond or provide other security in any form *955 and amount necessary to ensure payment of costs on appeal.” Fed. R.App. P. 7. Wilkinson аrgues that the phrase “costs on appeal” does not include attorney’s fees. Plaintiffs-Appellees contend that “costs on appeal” includes attorney’s fees if they are described as “costs” by an applicable fee-shifting statute or if the appeal is likely to be found frivolous by the court of appeals.
Ordinarily, “[w]e review objections to the amount of a bond for abuse of discretion.”
A & M Records, Inc. v. Napster, Inc.,
A. “Costs on Appeal” Under Rule 7 May Include Attorney’s Fees
Whether attorney’s fees are part of “costs on appeal” under Rule 7 is a question of first impression in this circuit. Six other circuits are split on the question. An older, minority rule, used by the D.C. and Third Circuits and endorsed by the Wright, Miller
&
Cooper treatise, holds that the “costs referred to” in Rule 7 “are simply those that may be taxed against an unsuccessful litigant under Federal Appellate Rule 39, and do not include attorney’s fees that may be assessed on appeal.”
In re Am. President Lines, Inc.,
The D.C. Circuit appears to have been the first court of appeals to address the question. In
In re American President Lines,
the district court ordered a $10,000 Rule 7 bond including security for appellate attorney’s fees.
*956
The D.C. Circuit rejected each of these reasons and reduced the amount of the bond to the amount of costs recoverable under Rule 39. First, the court cоncluded, without discussion, that the definition of the term “costs on appeal” in Rule 7 is synonymous with the “costs” listed in Rule 39.
Id.
Therefore, “[t]he costs referred to [in Rule 7] ... are simply those that may be taxed against an unsuccessful litigant under[Rule] 39, and do not include attorneys’ fees that may be assessed on appeal.”
Id.
Second, the court rejected the argument that a district court may order payment of attorney’s fees in an appeal bond under its “inherent power,”
see
Fed. R.Civ.P. 83, observing that such power “really adds nothing to the authority already conferred by Rule 7.”
In re Am. President Lines,
Two years later, the First Circuit, without discussing
In re American President Lines
or examining the language, purpose, or history of Rule 7, upheld a bond including attorney’s fees on the ground that the district court “implied a view” that there was “a real possibility” the appeal would be found frivolous and sanctions would be ordered under Rule 38.
Sckolnick,
Ten years passed before the meaning of “costs on appeal” again received substantial appellate attention. Then, the Third Circuit, in
Hirschensohn v. Lawyers Title Insurance Corp.,
No. 96-7312,
The court briefly noted
Marek v. Chesny,
In
Marek,
the Supreme Court held that the term “costs” in Federal Rule of Civil Procedure 68 — which shifts to the offeree all “costs” incurred subsequent to an offer of judgment if the judgment finally obtained is not more favorable than the of
*957
fer — includes attorney’s fees awardable under 42 U.S.C. § 1988, which authorizes the district court to “allow the prevailing party ... a reasonable attorney’s fee as part of the costs.” 42 U.S.C. § 1988(b);
Marek,
One year after the Third Circuit’s decision in
Hirschensohn,
the Second Circuit reached the opposite result from the D.C. and Third Circuits, holding that a district court may include security for attorney’s fees in a Rule 7 bond so long as an applicable fee-shifting statute “explicitly authorizes attorney’s fees ‘as part of the costs’ ... upon appeal.”
Adsani,
In
Pedraza,
the Eleventh Circuit followed
Adsani
in holding that a Rule 7 bond may include appellate attorney’s fees if they could be recoverable to the appellee under the governing statute.
In
Young v. New Process Steel, LP,
The Sixth Circuit has recently adopted the reasoning of
Adsani
and
Pedraza
in
Cardizem,
holding that a Tennessee statute shifting fees to prevailing defendants supportеd including attorney’s fees in a Rule 7 bond.
We agree with the Second, Sixth, and Eleventh Circuits and hold that the term “costs on appeal” in Rule 7 includes all expenses defined as “costs” by an applicable fee-shifting statute, including attorney’s fees. We do so for a number of reasons. First, Rule 7 does not define “costs on appeal.” At the time of its adoption in 1968, however, a number of federal statutes — including the Clayton Act — had departed from the American rule by defining “costs” to include attorney’s fees.
Marek,
Second, Rule 39 does not contain any “expression[ ] to the contrary.”
See id.
at 9,
Third, while some commentators have criticized
Adsani
and
Pedraza
for “attaching] significant consequences to minor and quite possibly unintentional differences in the wording of fee-shifting statutеs,” 16A Wright, Miller & Cooper,
supra,
§ 3953,
Marek
counsels that we must take fee-shifting statutes at their word.
Fourth, allowing district courts to include appellate attorney’s fees in estimating and ordering security for statutorily authorized costs under Rule 7 comports •with their role in taxing the full range of costs of appeal. In practice, district courts are usually responsible at the conclusion of an appeal for taxing all appellate costs, including attorney’s fees, avаilable to the prevailing party under a relevant fee-shifting statute.
See Perkins v. Standard Oil Co. of Cal.,
B. Attorney’s Fees Under Section 4 of the Clayton Act
Plaintiffs-Appellees contend that the portion of the district court’s Rule 7 bond that included security for appellate attorney’s fees was proper because the fee-shifting provision in Section 4 of the Clayton Act, 15 U.S.C. § 15(a), includes attorney’s fees as recoverable costs. We agree that Section 4 includes attorney’s fees as costs, but conclude that attorney’s fees would not be recoverable under Section 4 against Appellant Wilkinson. We therefore hold that the district court erred when it included anticipated appellate attorney’s fees in its calculation of the amount of the Rule 7 bond.
Section 4 provides that “any person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws ... shall recover threefold the damages by him sustained, and the cost of suit, including a reasonable attorney’s fee.”
Id.; see Marek,
However, unlike some other fee-shifting provisions, Section 4 is asymmetrical.
Compare,
15 U.S.C. § 15(a),
with
17 U.S.C. § 505,
and
42 U.S.C. § 1988(b);
see also Aetna Cas. & Sur. Co. v. Liebowitz,
Thus, a district court can order only a losing defendant — the party that has violated antitrust laws — to pay attorney’s fees under Section 4.
See Byram Concretanks, Inc. v. Warren Concrete Prods. Co.,
The asymmetry of Section 4 is consistent with the purpose of the Clayton Act as well as settled precedent. While the interests of an antitrust settlement class member who challenges the settlement on appeal may well be adverse to the interests of a class member who supports it, both remain the alleged victims, rather than perpetrators, of the claimed antitrust injury. Ordering one class member to pay other class members’ appellate attorney’s fees because of a disagreеment about the propriety of settlement would not serve the purpose of Section 4 to penalize and deter those who have violated the antitrust laws. Thus, even assuming, arguendo, that Plaintiffs-Appellees are otherwise eligible to collect fees under Section 4, they could not collect them from Wilkinson.
Cf. City of Detroit v. Grinnell Corp.,
C. Attorney’s Fees Based on Frivolous Appeal
As an alternate basis for including security for appellate attorney’s fees in its Rule 7 bond, the district court concluded that we were likely to find Wilkinson’s appeal on the merits frivolous and to award attorney’s fees as a sanction under Rule 38. While we affirm the district court’s decision on the merits, we do not conclude that Wilkinson’s appeal is frivolous. Even if we were to conclude that her appeal was frivolous, however, we would reverse the district court’s inclusion of appellate attorney’s fees on that basis.
Award of appellate attorney’s fees for frivolousness under Rule 38 is highly exceptional, making it difficult to gauge prospectively, and without the benefit of a fully developed appellate record, whether such an award is likely.
Cf. Primus Auto. Fin. Servs., Inc. v. Batarse,
*961
We agree with the D.C. Circuit that the question of whether, or how, to deter frivolous appeals is best left to the courts of appeals, which may dispose of the appeal at the outset through a screening process, grant an appellee’s motion to dismiss, or impose sanctions including attorney’s fees under Rule 38.
In re Am. President Lines,
D. Security for Attorney’s Fees Under Rule 7 Not Mandatory
Although we hold that security for appellate attorney’s fees may be included in a Rule 7 bond, we emphasize that the rule states that a district court “may,” rather than “shall,” impose a bond for costs on appeal. Fed. R.App. P. 7. A district court need not order that appellate attorney’s fees be secured in a Rule 7 bond merely because an applicable fee-shifting provision includes them as part of its definition of costs. Requiring security for anticipated appellate attorney’s fees under Rule 7 may be improper, notwithstanding an applicable fee-shifting provision, where other factors, such as financial hardship, indicate that the bond would unduly burden a party’s right to appeal.
See
E. Motion to Dismiss for Failure to Post the Bond
Finally, we address Plaintiffs-Appellees’ motion to dismiss Wilkinson’s merits appeal for failure to post the Rule 7 bond. Where an appellant has failed to pay an appeal bond, it is within our sound discretion to dismiss the appeal.
Hagan v. Whitman,
Our case law offers little guidance on how we should exercise our discretion when an appellant has failed to post a Rule 7 bond.
Hagan,
our most recent published opinion on this question, is more than forty years old. In that case, we dismissed an appeal where аppellants failed to post a bond for appellate costs ordered under former Federal Rule of Civil Procedure 73(e), on which the later-adopted Rule 7 was modeled.
Hagan,
More helpful than our decision in
Hagan
is a recent decision by the Sixth Circuit,
In re Cardizem CD Antitrust Litigation,
in which the court dismissed the appeal of a named plaintiff who objected to a proposed settlement in a nationwide antitrust class action based on the plaintiff-appellant’s failure to post a Rule 7 bond of $174,429 covering security for “filing and brief preparation costs,” “incremental administration
*962
costs,” and “projected attorneys’ fees.”
We conclude, on the facts of this case, that the factors discussed in Cardizem do not support dismissal of Wilkinson’s appeal. First, in contrast to the appellant in Cardizem, Wilkinson did proffer payment of the undisputed portion of the bond, $2,000.00, to the district court clerk, which was refused. Wilkinson then moved in the district court to reduce the bond amount. When her motion was denied, she appealed the bond ordеr. Although Wilkinson did not move to stay the bond, she did not simply “ignore [the] order,” id., but rather made legitimate efforts to reduce its amount. Her diligence in this respect weighs against dismissal of her appeal.
Second, in contrast to Cardizem, where the appellant “made no effort in the district court to justify her failure to post the bond,” id., Wilkinson has consistently argued that the amount of the bond was legally erroneous because neither Rule 7 nor Section 4 of the Clayton Act supports the district court’s order requiring security for appellate attorney’s fees. Although we have rejected Wilkinson’s argument concerning Rule 7, we conclude that her reading of Clayton Act Section 4 is correct. While a meritorious legal argument for reducing the amount of a Rule 7 bond might not excuse its nonpayment in all circumstances, this factor weighs against dismissal here.
Third, in contrast to Cardizem where the court concluded that the appellant’s appeal lacked merit, Wilkinson’s appeal raises legitimate questions about class certification, notice, and the settlement’s fairness, reasonableness, and adequacy.
Finally, we reject Plaintiffs-Appellees’ argument that Wilkinson’s failure to pay the bond has caused them undue prеjudice by delaying completion of the settlement. Any delay in completion of the settlement stems from Wilkinson’s appeal itself, not from her failure to pay the bond.
We therefore decline to dismiss Wilkinson’s appeal on the merits.
Conclusion
For the foregoing reasons, we hold that the district court erred in including $40,000.00 in security for appellate attorney’s fees in the $42,000.00 bond Wilkinson was ordered to pay under Rule 7. We accordingly vacate that portion of the bond. We decline to dismiss Wilkinson’s appeal based on her nonpayment of the bond and have decided the merits of the appeal in a concurrently filed memorandum disposition.
Appeal Bond Order VACATED in part; Motion to Dismiss Appeal on the Merits DENIED.
