delivered the opinion of the Court.
This is an admiralty case in which the plaintiff’s loss was primarily attributable to its own negligence. The question presented is whether that fact, together with the existence of a genuine dispute over liability, justified the District Court’s departure from the general rule that prejudgment interest should be awarded in maritime collision cases.

Respondents are the owner and the insurers of the E. M. Ford, a ship that sank in Milwaukee’s outer harbor on Christmas Eve 1979. At the time of this disaster, the Ford was berthed in a slip owned by the city of Milwaukee (City). In the course of a severe storm, she broke loose from her moorings, battered against the headwall of the slip, took on water, and sank. She was subsequently raised and repaired.
In 1980 the Ford’s owner, the Cement Division of National Gypsum Co. (National Gypsum), brought suit against the City, invoking the District Court’s admiralty and maritime *191 jurisdiction. 1 The complaint alleged that the City had breached its duty as a wharfinger by assigning the vessel to a berthing slip known to be unsafe in heavy winds and by failing to give adequate warning of hidden dangers in the slip. The plaintiff sought damages of $4.5 million, later increased to $6.5 million. The City denied fault and filed a $250,000 counterclaim for damage to its dock. The City alleged that National Gypsum was negligent in leaving the ship virtually unmanned in winter, with no means aboard for monitoring weather conditions or summoning help.
In 1986 the District Court conducted a 3-week trial on the issue of liability. Finding that both National Gypsum and the City had been negligent, the court determined that the owner bore 96% of the responsibility for the disaster, while the City bore 4% of the fault. Given the disparity in the parties’ damages, a final judgment giving effect to that allocation (and awarding the damages sought in the pleadings) would have essentially left each party to bear its own losses.
Respondents took an interlocutory appeal from the District Court’s ruling.

The Court of Appeals for the Seventh Circuit agreed with the District Court’s conclusion that both parties were at fault, and that the owner’s negligence was “more egregious” than the City’s, but it rejected the allocation of 96% of the responsibility to the owner as clearly erroneous.

v.
Milwaukee,
Thereafter the parties entered into a partial settlement fixing respondents’ damages, excluding prejudgment interest, at $1,677,541.86. 3 The parties agreed that any claim for interest would be submitted to the District Court for decision. A partial judgment for the stipulated amount was entered and satisfied.
Respondents then sought an award of over $5.3 million in prejudgment interest. 4 The District Court denied respondents’ request. It noted that “an award of pre judgment interest calculated from the date of the loss is the rule rather than the exception in cases brought under a district court’s admiralty jurisdiction,” App. to Pet. for Cert. 21a, but held that special circumstances justified a departure from that rule in this case. The court explained:
“In the instant case the record shows that from the outset there has been a genuine dispute over [respondents’] good faith claim that the City of Milwaukee was negligent for failing to warn the agents of [National *193 Gypsum] (who were planning to leave the FORD unmanned during the Christmas holidays) that a winter storm could create conditions in the outer harbor at Milwaukee which could damage the ship. The trial court and the court of appeals both found mutual fault for the damage which ensued to the ship and to the [City’s] dock. The court of appeals ascribed two-thirds of the negligence to [National Gypsum]. Thus, in this situation the court concludes that [National Gypsum’s] contributory negligence was of such magnitude that an award of prejudgment interest would be inequitable.” Id., at 22a. 5
The Court of Appeals reversed.
The Court of Appeals’ decision deepened an existing Circuit split regarding the criteria for denying prejudgment interest, in maritime collision cases. Compare,
e.g., Inland

Although Congress has enacted a statute governing the award of postjudgment interest in federal court litigation, see 28 U. S. C. § 1961, there is no comparable legislation regarding prejudgment interest. Far from indicating a legislative determination that prejudgment interest should not be awarded, however, the absence of a statute merely indicates that the question is governed by traditional judge-made principles.
Monessen Southwestern R. Co.
v.
Morgan,
Throughout our history, admiralty decrees have included provisions for prejudgment interest. In
Del Col
v.
Arnold,
The Courts of Appeals have consistently and correctly construed decisions such as these as establishing a general rule that prejudgment interest should be awarded in maritime collision cases, subject to a limited exception for “peculiar” or “exceptional” circumstances. See,
e. g., Inland Oil & Transport Co.,
The essential rationale for awarding prejudgment interest is to ensure that an injured party is fully compensated for its loss.
7
Full compensation has long been recognized as a
*196
basic principle of admiralty law, where
“[rjestitutio in inte-grum
is the leading maxim applied by admiralty courts to ascertain damages resulting from a collision.”
Standard Oil Co. of N. J.
v.
Southern Pacific Co.,
Despite admiralty’s traditional hospitality to prejudgment interest, however, such an award has never been automatic. In
The Scotland,
In this case, the City asks us to characterize two features of the instant litigation as sufficiently unusual to justify a departure from the general rule that prejudgment interest should be awarded to make the injured party whole. First, the City stresses the fact that there was a good-faith dispute *197 over its liability for respondents’ loss. In our view, however, this fact carries little weight. If interest were awarded as a penalty for bad-faith conduct of the litigation, the City’s argument would be well taken. But prejudgment interest is not awarded as a penalty; it is merely an element of just compensation.
The City’s “good-faith” argument has some resonance with the venerable common-law rule that prejudgment interest is not awarded on unliquidated claims (those where the precise amount of damages at issue cannot be computed). If a party contests liability in good faith, it will usually be the case that the party’s ultimate exposure is uncertain. But the liquidated/unliquidated distinction has faced trenchant criticism for a number of years.
9
Moreover, that distinction “has never become so firmly entrenched in admiralty as it has been at law.”
Moore-McCormack Lines, Inc.
v.
Richardson,
*198
In sum, the existence of a legitimate difference of opinion on the issue of liability is merely a characteristic of most ordinary lawsuits. It is not an extraordinary circumstance that can justify denying prejudgment interest. See
Alkmeon Naviera,
The second purportedly “peculiar” feature of this case is the magnitude of the plaintiff’s fault. Leaving aside the empirical question whether such a division of fault is in fact an aberration, it is true in this case that the owner of the E. M. Ford was primarily responsible for the vessel’s loss. As a result, it might appear somewhat inequitable to award a large sum in prejudgment interest against a relatively innocent party. But any unfairness is illusory, because the relative fault of the parties has already been taken into consideration in calculating the amount of the loss for which the City is responsible.
In
United States
v.
Reliable Transfer Co.,
*199
In light of
Reliable Transfer,
we are unmoved by the City’s contention that an award of prejudgment interest is inequitable in a mutual fault situation. Indeed, the converse is true: a
denial
of prejudgment interest would be unfair. As Justice Kennedy noted while he was sitting on the Ninth Circuit, “under any rule allowing apportionment of liability, denying prejudgment interest on the basis of mutual fault would seem to penalize a party twice for the same mistake.”
Alkmeon Naviera,
Accordingly, we hold that neither a good-faith dispute over liability nor the existence of mutual fault justifies the denial of pre judgment interest in an admiralty collision case. Questions related to the calculation of the prejudgment interest award, including the rate to be applied, have not been raised in this Court and remain open for consideration, in the first instance, by the District Court.
The judgment of the Court of Appeals is
Affirmed.
Notes
“The district courts shall have original jurisdiction, exclusive of the courts of the States, of: (1) Any civil case of admiralty or maritime jurisdiction, saving to suitors in all cases all other remedies to which they are otherwise entitled.” 28 U. S. C. § 1333(1).
Such appeals are authorized by 28 U. S. C. § 1292(a)(3), which states:
“(a) Except as provided in subsections (c) and (d) of this section, the courts of appeals shall have jurisdiction of appeals from: ... (3) Interlocutory decrees of... district courts or the judges thereof determining the rights and liabilities of the parties to admiralty cases in which appeals from final decrees are allowed.”
In arriving at this sum, the parties agreed that respondents’ damages were slightly more than $5.4 million, while the City’s damages were just over $192,000. The parties multiplied respondents’ damages by one-third, resulting in a subtotal of $1,805,829.98 for which the City was responsible. From this subtotal, the parties subtracted two-thirds of the City’s damages, or $128,288.12, as an offset because that was the amount of National Gypsum’s responsibility. The difference was the City’s obligation to respondents. App. 40-45.
This figure was based on respondents’ assertion that pre judgment interest should be compounded continuously, from the time of the sinking of the Ford, at the commercial prime rate of interest averaged over the period of assessment. Plaintiff’s Brief on Issue of Prejudgment Interest in No. 80-C-1001 (ED Wis.), pp. 24-26. The District Court did not express any view on the correctness of this analysis, nor do we. We merely note in passing that the discrepancy between the damages award and the interest sought by National Gypsum is in some measure attributable to the delays that have plagued this litigation — a factor that does not appear to be traceable to the fault of any party.
The District Court also relied on the City’s status as a municipality as an alternative ground for denying prejudgment interest. App. to Pet. for Cert. 22a-23a. The Court of Appeals rejected this portion of the District Court’s analysis as inconsistent with Circuit precedent, and the City did not pursue the argument in this Court.
