This аppeal requires us to review the propriety of an award of damages in admiralty and the imposition of a maritime lien on a pleasure yacht. Plaintiff-appellant/Cross-appellee Sweet Pea Marine, Ltd. (“Sweet Pea”), a Cayman Islands corporation whose sole enterprise is the upkeep and management of the vessel MTV SWEET PEA (“the Vessel”), appeals the district court’s omnibus order in which it: (1) entered the jury’s verdict against Defendant-appellee/Cross-appellant APJ Marine, Inc. (“APJ”) in the amount of $243,904 on Sweet Pea’s claims brought on the basis of diversity jurisdiction; and (2) awarded APJ $244,689.31 in damages on its in personam maritime claim against Sweet Pea and its in rem maritime lien claim against the Vessel. Because there was complete diversity of citizenship between the parties when the case was filed, the district court’s exercise of federal subject matter jurisdiction over Sweet Pea’s claims was not improper. Because APJ failed to offer at trial any evidence on a required element of its аdmiralty claims, however, the district court’s award of damages to APJ and its imposition of a maritime lien against the Vessel were clearly erroneous. Accordingly, the district court’s order is AFFIRMED in part, VACATED in part, and REMANDED.
I. BACKGROUND
This appeal arises from a dispute about an oral contract to outfit and remodel the interior of the Vessel, a 127-foot pleasure yacht. In September 1999, Alan Jellis, on behalf of APJ, met with Bobby Stevenson 1 to discuss the renovation of the Vessel. At that meeting, Jellis and Stevenson reached an oral agreement which the district court found included the following terms: (1) APJ would redesign and refit the interior of the Vessel and warranty that the work would result in a “world class vessel”; (2) the scope of the project may change and evolve over time; (3) the interior work would be done in tandem with engineering, electrical, and mechanical work being done by other parties; (4) the interior work was estimated to be completed within 9-12 months and would cost $1.75 million; and (5) APJ would be paid as follows: (a) Labor: Jellis would be paid $85/hour; skilled laborers would be paid $56/hour; semi-skilled laborers would be paid $36/ hour; unskilled laborers would be paid $26/hour; and there would be no additional “mark-up” for work performed by these subcontractors; (b) Materials/Goods: APJ would add a 15% mark-up when it charged Sweet Pea for materials and supplies bought by APJ for the Vessel from vendors. In November/December 2000, the parties modified the contract such that APJ was responsible for the engineering, electrical, and mechanical work being done on the Vessel in addition to the interior work and, as a result, Jellis’s pay rate was increased to $125/hour.
During the early part of 2001, Sweet Pea began to have problems with the work being done by APJ. APJ was behind schedule and kept submitting to Sweet Pea longer timetables for completion and increased cost estimates. Despite these problems, however, Sweet Pea continued to pay APJ for its work. In June 2001, Sweet Pea had Jellis and APJ audited and discovered irregularitiеs in APJ’s billing practices. For example, Sweet Pea’s accountant found that APJ used subcontractors to perform the interior Work; that these subcontractors were hiring unskilled workers for $11/hour but were billing them at $22/hour as semi-skilled worker to APJ; and that APJ was then billing these work *1246 ers to Sweet Pea as skilled workers at $56/hour. As a result of these irregularities and APJ’s failure to complete the job according to its estimated schedule, Sweet Pea terminated APJ in November 2001.
At that point, Sweet Pea had paid APJ $4.3 million аccording to the agreed-upon rates ($355,000 went directly to APJ or Jellis and the rest was paid to vendors and laborers). In March 2002, APJ sent Sweet Pea a bill for $1,292 million for outstanding costs it had incurred prior to its termination. According to the bill, APJ had spent $5.6 million on the renovation of the Vessel ($3.67 million for labor, $1,878 million for materials/supplies, and $55,755 in petty cash), and was paid only $4.3 million by Sweet Pea. Sweet Pea refused to pay the outstanding balance.
On 17 May 2002, Sweet Pea filed a complaint against APJ in fedеral court based on diversity jurisdiction and alleged breach of an oral contract, negligent misrepresentation, fraud in the inducement, breach of an oral express warranty, and breach of fiduciary duties. In response, on 22 May 2002, APJ filed a complaint in personam against Sweet Pea and in rem against the Vessel for the $1,292 million it claimed it was owed for work performed on the Vessel. APJ’s claims were brought in federal court under admiralty jurisdiction, and therefore were framed as a breach of an oral contract under mаritime law and as a maritime lien claim, rather than a claim for quantum meruit. The district court then issued a show cause order to require APJ to demonstrate why its admiralty claims should not be dismissed with instructions that it file the claims as counterclaims to the diversity action initiated by Sweet Pea. .Although the district court initially dismissed APJ’s complaint, it granted APJ’s motion to reconsider because Sweet Pea had deposited a bond pursuant to admiralty law procedure to secure the Vessel in the in rem action, and APJ wаs concerned that a dismissal would forfeit its interest in that bond. Accordingly, the district court consolidated the two actions for discovery purposes, but allowed them to proceed on separate dockets.
On 20 October 2003, a two-week jury trial commenced in which both actions were tried together. Because Sweet Pea had demanded a jury for its diversity claims, the jury was allowed to render a verdict on Sweet Pea’s claims. Because APJ’s admiralty claims precluded resort to a jury, the district court allowed the jury to issue an advisory opinion on APJ’s admiralty claims, but insisted that it would make the ultimate findings of fact for APJ’s claims. At the conclusion of the trial, the jury found for Sweet Pea on its breach of warranty claim and awarded it $239,000. The jury also found for Sweet Pea on its negligent misrepresentation and breach of fiduciary duty claims, but did not award any damages for these claims. The jury found for APJ on the breach of contract and fraud claims. In addition, in its advisory capacity, the jury found for APJ on its maritime claims in the amount of $244,000. Turning to APJ’s claims, the district court found that the jury ruled against Sweet Pea on its contract-related claims, and therefore res judicata did not preclude it from reaching APJ’s maritime contract claims. The district court found that APJ was not entitled to any compensation for labor performed by subcontractors because it had already been paid by Sweet Pea for the work performed and APJ was not entitled, under the terms of the oral contraсt, to any mark-up over the rate at which the subcontracted workers were billed to Sweet Pea. However, the district court found that APJ was entitled under the oral contract to a mark-up on goods and materials supplied to the Vessel, and that APJ had not yet recovered the agreed-upon mark-up. Accordingly, based *1247 on its conclusion that Exhibit 5 showed that APJ had paid $1,631,262.15 to vendors for goods and materials, the court multiplied that number by 15% and ruled that Sweet Pea owed APJ $244,689.31 in damages. The district court also imposed a maritime lien on the Vessel in the same amount.
On appeal, APJ argues that the district court lacked jurisdiction over Sweet Pea’s diversity claims because Sweet Pea’s principal place of business was Florida and APJ was a Florida corporation. For its part, Sweet Pea argues that the district court erred by awarding APJ damages and imposing a maritime lien on the Vessel because APJ failed to present sufficient evidence on the required elemеnts of its claims. Alternatively, Sweet Pea argues that the district court erred by refusing to set off its award of damages on APJ’s admiralty claims with the jury’s award of damages on Sweet Pea’s diversity claims. We will address each argument in turn.
II. DISCUSSION
A. Jurisdiction Over Sweet Pea’s Diversity Claims
Because federal courts are courts of limited jurisdiction, we must address as a threshold matter APJ’s argument that the district court lacked subject matter jurisdiction.
See Steel Co. v. Citizens for a Better Env’t,
Subject matter jurisdiction based on diversity of citizenship exists in civil actions where thе amount in controversy exceeds $75,000 and the action is between “citizens of different States and in which citizens or subjects of a foreign state are additional parties.” 28 U.S.C. § 1332(a)(3). Diversity jurisdiction requires complete diversity between named plaintiffs and defendants.
See Ruhrgas AG v. Marathon Oil Co.,
Based on these standards, the district court’s exercise of diversity jurisdiction was not improper. It was undisputed that the amount in controversy requirement was met and that Stevenson was a citizen of Texas, Sweet Pea was a Cayman
*1248
Islands corporation, and Jellis and APJ were Florida citizens. Accordingly, APJ’s argument hinges on its assertion that Sweet Pea’s PPB was in Florida. With regard to Sweet Pea’s PPB, however, the district court recited several facts which supported a finding that Sweet Pea’s PPB was in the Cayman Islands: (1) Sweet Pea’s mailing address was in the Cayman Islands; (2) the corporate records were maintained in the Cayman Islands; (3) the directors of Sweet Pea were located in the Cayman Islands; (4) annual meetings were held in the Cayman Islands; and (5) the Vessel, which was essentially Sweet Pea’s only asset, was flagged under the Cayman Islands.

B. Award of Damages and Imposition of a Maritime Lien in Favor of APJ
Next, we examine Sweet Pea’s argument that the district court erred by awarding damages to APJ and imposing a maritime lien on the Vessel. “In reviewing a judgment of a trial court, sitting without a jury in admiralty, the Court of Appeals may not set aside the judgment
*1249
below unless it is. clearly erroneous.”
McAllister v. United States,
Federal admiralty jurisdiction is invoked by a claim that an oral contract regarding the repair of a vessel was breached.
See Hatteras of Lauderdale, Inc. v. Gemini Lady,
Because Sweet Pea argues,
inter alia,
that APJ failed to present any evidence that the charges for goods and materials listed in Exhibit 5 were reasonable, we focus our inquiry on the few cases which have construed the reasonableness element in APJ’s admiralty claims. According to these cases, the “reasonableness” of charges, in the maritime context, is measured by whether they are “customary,”
Ex parte Easton,
Based on these standards, Sweet Pea argues that APJ failed to present any evidence by which the finder of fact could have determined that the charges summarized in Exhibit 5 were reasonablе.

APJ
*1250
makes two arguments in response. First, APJ argues that Sweet Pea waived its ability to contest the reasonableness of charges for goods and materials because, as the district court found, Sweet Pea agreed to a 15% mark-up on goods and materials purchased by APJ. That the parties agreed to a general mark-up on goods and materials, however, has no relevance for whether the actual prices of those goods and materials subject to the mark-up were reasonable. While the inclusion of a mark-up does not necessarily bar a maritime lien claim,
see Galehead, Inc. v. M/V Anglia,
Second, in its brief, APJ cites generally a 120-page span of trial testimony and asserts that it adduced evidence which established . the reasonableness of the charges in Exhibit 5.
5
A thorough review of the testimony cited by APJ, however, demonstratеs otherwise. In fact, in our review of the entire record, we discovered a dearth of any evidence submitted by APJ which would support the inference that the charges for goods and materials were reasonable. In its case in chief, no witness for APJ directly testified that the charges listed in Exhibit 5 were reasonable based on industry standards. Likewise, there was no indirect evidence by which a trier of fact could conclude that APJ satisfied its burden on the reasonableness element. For examрle, there were several instances in which witnesses for APJ testified that the mark-up on goods and materials bought by APJ was “reasonable.”
See
R8 at 1298-99,1426. However, as we noted in our disposition of APJ’s first waiver argument, testimony about the reasonableness of the mark-up does not establish that the underlying prices subject to the mark-up were reasonable. In addition, APJ offered testimony from Jellis that the invoices which were used to create Exhibit 5 represented the “at cost” price — i.e., without any mark-up — that APJ purchased goods and materials from vendors.
See
R6 at 810, R7 at 1081, 1119. Stating what APJ paid for goods and materials, however, in the absence of any evidence of comparable industry pricing to benchmark the pricing for these goods and materials, does not provide any basis for a trier of fact to conclude that APJ paid reasonable prices for the goods and materials. In fact, Jellis admitted that he would routinely receive invoices from vendors and forward them to Stevenson for payment without any inquiry into the reasonableness of what was being charged.
See
R6 at 857; R7 at 1150. Moreover, there was no evidence that APJ sought bids from various suppliers and
*1251
ultimately contracted with the low-cost provider. Accordingly, testimony regarding what the goods and materials “cost” APJ cannot be taken as probative of the reasonableness of the charges in Exhibit 5. In addition, Jellis testified that he would refrain from charging Sweet Pea for certain items, which ultimately discounted the total amount оf charges APJ billed to Sweet Pea.
See
R6 at 883. Assuming some of these “discounts” resulted in the exclusion of certain goods and materials from Exhibit 5, this evidence still does not speak to the reasonableness of the charges actually listed in Exhibit 5. Finally, we note that while there was testimony that the labor rates charged by APJ for subcontractors were reasonable based on the industry standard,
see
R8 at 1298, 1426, the reasonableness of these rates have no bearing on whether the prices for goods and materiаls bought from vendors were reasonable. In sum, our review of the record confirms that APJ presented no evidence by which a trier of fact could infer that the charges listed in Exhibit 5 were reasonable according to industry standards. Accordingly, because such a showing was a required element for APJ’s maritime claims, the district court’s award of damages in favor of APJ and its imposition of a maritime lien on the Vessel were clearly erroneous.
See Hart v. Yamaha-Parts Distribs., Inc.,
C. Refusal to Set Off Diversity and Admiralty Judgments
Finally, Sweet Pea argues that the district court erred by refusing to set off its judgment in favor of APJ on its maritime claims against the jury’s award to Sweet Pea on its diversity claims because the claims were derived from the identical set of operative facts.
See Blount v. Windley,
III. CONCLUSION
In this appeal, we were required to review the propriety of the district court’s exercise of diversity jurisdiction and its disposition of admiralty claims. As we have explained, because the district court properly found that Sweet Pea’s principal place of business did not destroy complete diversity, its exercise of jurisdiction over Sweet Pea’s diversity claims was not improper. The district court’s award of damages in favor of APJ and its imposi
*1252
tion of a maritime lien on the Vessel, however, were clearly erroneous. Maritime liens “encumber commerce,”

. We note that while the burden to establish the existence of federal subject matter jurisdiction rests with the party bringing the claim, a corporation's citizenship by virtue of its principal place of business need not be conclusively determined to satisfy § 1332 provided the party asserting the claim demonstrates diversity by conclusively establishing the corporation’s citizenship by virtue of its State of incorporation and by demonstrating that the corporation's PPB is not in a State which would destroy complete diversity.
See Walker v. Armco Steel Corp.,
. While the jury, in its advisory capacity, made an implicit finding on the reasonableness element by awarding damages to APJ on its admiralty claims, this determination should have had no binding effect on the district court.
See Sherman
v.
Burke Contracting, Inc.,
. We note that APJ makes an additional waiver argument on appeal. Based on its reading of an isolated remark by Sweet Pea's counsel, see R8 at 1412-13, APJ argues that Sweet Pea conceded that the charges in Exhibit 5 were reasonable and therefore waived its ability to contest reasonableness on appeal. Our review of the record, howevеr, reveals that Sweet Pea’s counsel was remarking on the admissibility of such evidence and not whether it conclusively established APJ’s burden on the reasonableness element. Moreover, because the record demonstrates that counsel for Sweet Pea repeatedly argued that APJ had not met its burden on the reasonableness element following the colloquy cited by APJ, see, e.g., R8 at 1510-11, 1550, we reject APJ’s argument that Sweet Pea conceded the reasonableness of APJ’s charges for gоods and materials.
. Because the district court specifically ruled that Exhibit 5 was not to be construed as evidence of the reasonableness of APJ’s payments to vendors for goods and materials, see R6 at 734, the admission into evidence of Exhibit 5 did not satisfy APJ’s burden. Accordingly, APJ had the burden to offer testimony or other evidence regarding the reasonableness of the charges.
. In, addition to its argument about the lack of evidence on the reasonableness element, Sweet Pea argues that APJ also failed to produce sufficient evidence that the goods and materials were actually delivered to the Vessel. See
