concurring in part and dissenting in part:
I concur in the majority decision insofar as it rules in favor of the plaintiffs on interest. Plaintiffs should indeed have the benefit of interest from when they became entitled by judgment to punitive damages, September 24, 1996, at the rate they properly claim, 5.9%.1 Exxon has had a half billion dollars of the plaintiffs’ money ever since the district court entered judgment in their favor. Interest is required to compensate the plaintiffs for the delay in paying the plaintiffs their money.
I am unable to concur regarding costs. Satisfying though it may be to shovel money from a large corporation to those whom it wronged, respect for the Supreme Court decision in this case and precedent in other circuits obligates us to award Exxon most, but not all, of its costs for its mostly successful appeal. As this case proceeded, the district court initially upheld all,2 and on remand, nearly all,3 of the punitive damages the jury awarded to the plaintiffs. We agreed with the plaintiffs that they were entitled to punitive damages,4 and held that half of the original award ($2.5 billion) was not too high.5 We turned out to be mistaken. The Supreme Court held that a tenth of the original award was as high as anyone — us, the district court, or the jury — could go.6 After overturning our decision, the Supreme Court awarded *1083costs to Exxon.7 Due respect for the Supreme Court’s decision obligates us, as a lower court, to exercise our discretion regarding costs in accord with how the Supreme Court exercised its discretion.
The majority says that Exxon “declares itself the winner,” but it was really the Supreme Court of the United States that declared Exxon the winner. Our liability ruling in favor of the plaintiffs was indeed left “undisturbed,” but only because the Court’s tie vote on liability left our decision in place as to that issue.8 The Court took pains to point out that leaving our decision in place did not mean we were correct.9
The liability determination, which squeaked by in the Supreme Court, was merely a stepping stone on the way to the destination. The destination was money. On the money, it turned out that we were way off. The Supreme Court held that our decision, which reduced the award to $2.5 billion, was still $2 billion too high and 5 times more than could properly be awarded.10 The Court concluded that the “upper limit” on the ratio of punitive damages to actual damages was 1 to l.11 Exxon thus obtained at least a 90% reduction in the punitive damages it owed.12 After the Supreme Court handed down its decision, Exxon and the plaintiffs agreed to a punitive damages award of $507.5 million. We accepted this partial settlement, so the amount of punitive damages is established at that amount.
The majority is correct that Exxon fought a “relentless ... battle” until the Supreme Court vacated the award for being far too high, but draws the wrong inference from the duration and intensity of that fight. Exxon was not obligated to accept our decision. Litigants have the right to appeal and petition for certiorari when in good faith they think a lower court has erred.13 Exxon appealed and fought. The Supreme Court determined that Exxon was largely correct, more right than we were. The law requires Exxon to be compensated in part for that battle, not punished for it, because it turned out that Exxon was largely entitled to prevail, despite our opinions to the contrary. Humility requires us to accept that.
Federal Rule of Appellate Procedure 39 governs the award of costs on appeal. Under the rule, how well or how poorly a party does on appeal determines whether that party may collect any money from its opponent to cover the costs of the appeal.14 It implements “the principle ... that all cost items expended in the prosecution of the proceeding should be borne by the unsuccessful party.”15 This ancient principle was set out in the Statute of Glouces*1084ter in 1275.16 It has been modified only in the details since its establishment. Neither the principle, nor our rule, use “costs” to mean what something actually cost. “Costs” means the certain listed expenditures a party has incurred for which it may seek reimbursement from the opposing party.17 Exxon is not entitled to seek reimbursement under Rule 39 of the fortune it undoubtedly spent on attorneys’ fees.18 Allowable costs under Rule 39, for preparation and transmission of the record, for the reporter’s transcript, and for filing a notice of appeal ($455), are relatively small.19 But the one remaining element of allowable costs, “premiums paid for a supersedeas bond or other bond to preserve rights pending appeal,” can be, and was in this case, huge.20
If this appeal were, as the majority suggests in justifying the denial of costs, primarily for the principle of the thing, Exxon need not have posted a supersedeas bond. Exxon could have pursued its appeal for no more than a few thousand dollars in record preparation expenses and filing fees, plus unrecoverable attorneys’ fees.21 But had Exxon appealed without posting a supersedeas bond, Exxon would have had to pay the plaintiffs all of the original judgment ($5 billion) in 1996, including the $4.5 billion that the Supreme Court held it did not owe. Given the practical difficulties of trying to get the money back over a decade later, at best the appeal would have generated a very expensive piece of paper saying that Exxon had overpaid by $4.5 billion.
To hold onto the money until the courts determined whether the $5 billion judgment was correct, Exxon had to secure payment of the judgment, guaranteeing that the money would be there for the plaintiffs if Exxon lost. Under Federal Rule of Civil Procedure 62(d), an appellant can stay execution of a money judgment by posting a supersedeas bond approved by the district court. Exxon obtained such a stay by posting a bond that secured the entire $5 billion judgment, plus interest.22 *1085Had Exxon not posted a supersedeas bond, the plaintiffs would have been entitled to take Exxon’s money, all $5 billion of the punitive damages award plus interest, 10 days after the district court entered judgment in the plaintiffs’ favor.23 The plaintiffs would then have been free to spend the money in the 13 intervening years as the appeals and remands dragged on.
The rationale for a supersedeas bond is that there can be no certainty about who is in the right until the appeals are done; the party that lost should not have to pay the winner until the district court’s decision is finally affirmed, but in the meantime, the party that won in district court should not be at risk of the money disappearing.24 To protect the winner from the risk that the loser will not have money if and when the judgment is affirmed, the bond is ordinarily secured by property or by surety. The surety, such as a bank or insurance company, obligates itself to pay the judgment creditor. In this case, the $5 billion judgment was secured by several banks (the judgment was apparently too big for one bank). The banks authorized an irrevocable25 letter of credit,26 which authorized the clerk of court to request payment of the judgment for the benefit of plaintiffs. To pay out the billions of dollars to the plaintiffs, all the clerk needed to do was sign a form saying “pay as directed in the attached order of the District Court,” like endorsing a traveler’s check or cashier’s check.
Sureties do not commit their credit for free. To hold onto the $5 billion until the appeals finished, Exxon had to pay the banks $60.6 million. Exxon paid 90% percent of this money, about $54.5 million dollars, for the right to hold onto the $4.5 billion plus interest that the Supreme Court concluded Exxon did not owe. Only 10% percent, about $6.1 million, bought the right to delay paying money that Exxon turned out to owe the plaintiffs. In other words, Exxon had to spend about $6 million to secure money it did owe, and over $50 million to shield money it did not owe, while it pursued its appeals.
The Supreme Court awarded costs in favor of Exxon against the plaintiffs, even though it rendered a split decision that left the plaintiffs with up to 10% of their victory.27 The majority does not follow the Supreme Court’s determination. Instead, the majority pretends that Exxon did not win, punishes it for fighting so long and hard, and denies Exxon any costs at all. Because Exxon won 90% percent of its case and paid 90% of the $60.6 million to *1086hold onto money it ultimately did not owe, Exxon ought to recover 90% of its allowable supersedeas bond costs. The $60.6 million was the price of Exxon’s train ticket to victory. The rules, in place with little change for many centuries, say that a party that wins on appeal is entitled to have the loser reimburse the price of that train ticket.28
Had Exxon won the case entirely, we would still have had discretion to deny costs, because Rule 39 says “unless ... the court orders otherwise.”29 The strong presumption in favor of awarding costs to the prevailing party would have made such an exercise of discretion unlikely.30 When a court has discretion, ordinarily the question is whether the court has abused its discretion. Not infrequently this court reverses district courts for abusing their discretion. Likewise, we ourselves must not abuse our discretion. We do so here, unfortunately, by denying all costs whatsoever.
What persuades me that we are abusing our discretion is the Supreme Court’s exercise of its discretion in this case. The Supreme Court awarded costs entirely in favor of Exxon, even though it left our liability decision standing on a tie vote and allowed for a half billion punitive damages award in favor of the plaintiffs on remand.31 Just as the Supreme Court’s decision binds us, its exercise of discretion should guide us. The Supreme Court concluded that Exxon prevailed to so great a degree as to deserve costs. As a lower court implementing the Supreme Court’s decision on remand, we abuse our discretion by pretending otherwise.
The majority evades this obligation by arguing that there is a substantive, and not merely verbal, difference between the Supreme Court rule on costs and ours. There is not. The Supreme Court’s rule says “[i]f the Court reverses or vacates a judgment, the respondent or appellee shall pay costs unless the Court otherwise orders.” 32 Our rule says that “if a judgment is affirmed in part, reversed in part, modified, or vacated, costs are taxed only as the court orders.”33 From the tone of the language, one might (the majority does not) tease out a theory that the Supreme Court rule connotes a somewhat more favorable inclination toward costs than our rule, but such an inference would be too gossamer, and any attendant presumption too weak, in the face of plainly discretionary language for both courts.
For both our rule and the Supreme Court’s rule, the words are discretionary, “unless the Court otherwise orders” in the Supreme Court,34 “only as the court orders” here.35 In substance the rules are the same, leaving costs to the court’s discretion. They do so against the background of our legal system, which has, for the better part of a millennium,36 awarded *1087costs to prevailing plaintiffs, and for about half a millennium to whichever party prevailed.37 As for who the prevailing party is, we have in all our decisions been much closer to plaintiffs’ view of the case, but the Supreme Court disagreed and is, after all, supreme.
The Second Circuit addressed the similarity of the costs rules in its scholarly opinion, Furman v. Cirrito.38 In that case, as here, the Supreme Court had reversed the court of appeals. On remand, the party that won costs in the Supreme Court under its Rule 4339 sought them in the court of appeals under Rule 39.40 Furman holds that despite the slight verbal differences, “[t]he language of the district, circuit, and Supreme Court rules that confer discretion to award costs is almost identical,” so a Supreme Court reversal and award of costs “entitles” the victor there to costs in the court of appeals.41 The Second Circuit explained that just as a district court on remand must follow a circuit court’s decision when taxing costs, a circuit court’s award of costs should be consistent with the Supreme Court’s decision.42 Since the Supreme Court reversed the Second Circuit and awarded costs under its rule to the appellants, Furman held that proper deference to the Supreme Court’s decision meant the appellants should also be considered prevailing parties for the purposes of Rule 39, entitling them to appellate costs.43 Because neither our rule, nor the factual circumstances before us, differ materially from those before the Supreme Court, our decision on costs should, like Furman, be consistent with the Supreme Court’s decision. The Supreme Court awarded costs in favor of Exxon, and we abuse our discretion by defying its judgment.
The only distinction that could arguably be drawn between Furman and our case is that Furman was not a decision that left each side with something. But both our cases and those of our sister circuits have addressed what is to be done in that circumstance as well. Costs go to the “prevailing party.”44 Our case law holds that a party “need not prevail on every issue, or even on the ‘central issue’ in the case, to be considered the prevailing party.”45 A party “prevails” when it wins substantial *1088relief; the amount of the cost award is determined by looking at the extent of the party’s success.46 As far as awards of appellate costs go, we have awarded costs to the party that “substantially and primarily prevailed on appeal.” 47
Likewise, the Seventh and Eighth Circuits both treat a defendant’s success in substantially reducing the size of the damages award as meriting costs for amounts paid to obtain supersedeas bonds. The Eighth Circuit held in Emmenegger v. Bull Moose Tube Co.48 that when the defendants succeeded in knocking several million dollars off the plaintiffs’ recovery, the defendants were properly awarded costs for the premiums on a supersedeas bond they paid to shield the money while they appealed.49 The costs defendants got in Emmenegger were for the portion of the supersedeas bond securing the portion of the judgment the defendants got erased, not the whole thing.50 We should exercise our discretion consistently with the Eighth Circuit’s approach.
The Seventh Circuit in Republic Tobacco Co. v. North Atlantic Trading Co.51 likewise upheld an award of costs for supersedeas bond expenses in a partial defense victory. Even though the plaintiffs wound up with $3 million out of a $18.6 million jury verdict (retaining a larger percentage of the original award than the plaintiffs in this case), the Seventh Circuit held that it was a proper exercise of discretion to tax the full costs incurred for the supersedeas bond.52 The Seventh Circuit suggested a better exercise of discretion would be the Eighth Circuit’s approach, awarding as costs the amount spent to secure the portion of the judgment vacated on appeal.53
The majority argues for disregarding the Seventh and Eighth Circuit cases because they speak to exercises of discretion by district courts, instead of exercises by appellate courts. But the discretionary authority of district courts, circuit courts, and the Supreme Court to award costs is conferred by rules that, as Furman holds, are in substance the same at all three levels.54 We, like district courts and the Supreme Court, have a duty to exercise our discretion fairly and not abuse it. *1089These precedents explain how that discretion may be properly exercised with regard to supersedeas bond costs and split decisions on appeal.
The D.C. Circuit exercised its own discretion, and did not merely analyze a district court’s exercise of discretion, in A Quaker Action Group v. Andrus,55 a case that had gone up five times on appeal and resulted in a partial victory for each side.56 Though neither party prevailed entirely, the D.C. Circuit made cost awards under Rule 39 in favor of the “predominately prevailing party.”57 Quaker Action held that the plaintiffs should recover 30% of their costs for the fifth appeal and 75% of their costs for the fourth appeal.58
Like the Seventh and Eighth Circuits, the D.C. Circuit awarded partial costs to the partial victor. Since the D.C. Circuit exercised its own discretion to award appellate costs in a split decision, the majority is simply cavilling when it suggests that the Seventh and Eighth Circuit decisions only speak to how circuit courts should review exercises of discretion. The majority would disregard Quaker Action Group because it is a “thirty-year-old out-of-circuit case.”59 Indeed it is. But our legal system has no sunset provision for precedents.60 We use decades-old and centuries-old precedents to achieve consistency over time.
The majority rejects the “mathematical” approach to supersedeas bond costs as a “thicket,” and says that awarding a partial victor the percentage of its supersedeas bond costs equal to the percentage of its victory would generate “wasteful litigation.” 61 The D.C. and Eighth Circuits had no trouble with arithmetic. Spending many thousands to litigate about $60.6 million is not “wasteful,” and taking 90% of a number is fourth grade arithmetic. This percentage approach is no more complicated than calculating a tip, not much of a “thicket.” Those who find it challenging could always use a calculator.
All the majority cites to support its exercise of discretion are cases in which we have not spoken to this issue at all. Every case the majority cites62 is a split decision in which we said, “[ejach party shall bear its own costs on appeal.” Each case says that without explanation and without any indication that the costs were even disputed. None contain a holding about the apportionment of supersedeas bond expenses. None even mention Rule 39, let alone discuss when or how a court should award appellate costs under it. There are, of course, numerous split decisions in which we did the opposite and awarded costs, rather than required each party to bear their own.63
*1090The problem is that majority uses these citations as decoration, as opposed to how citations are meant to be used, to assure that like cases are treated alike. We look to precedent because fairness requires that like cases be treated alike, instead of being treated differently according to how the judges feel. For guidance as to how costs should be awarded in this instance, there is no more analogous precedent than the Supreme Court’s award of costs in this very case. In the face of the Supreme Court’s decision overturning us, the majority chooses to not award costs, even though the United States Supreme Court chose to award them, to Exxon.
The plaintiffs were victims of Exxon’s malfeasance. They had to wait much too long for the punitive damages award. That wait is why they are entitled to interest.64 But Exxon had to pay for a supersedeas bond to secure $4.5 billion it did not owe. That is why Exxon is entitled to recover that portion of its costs under Rule 39.65 Whether we like it or not, Exxon got us overturned, and saved 90% of what the jury thought it should pay and 80% of what we thought it should pay by winning in the Supreme Court. The prevailing party has for many centuries been entitled to its costs. As for who in large part won the case in the Supreme Court, there cannot be serious doubt. The champagne corks that popped after the Supreme Court reversed us were doubtless on Exxon’s side, not the plaintiffs.
