Terra International, Inc., (Terra) appeals the district court’s
1
order granting Mississippi Chemical Corporation’s (MCC) motion to transfer this lawsuit to the United States District Court for the Southern District of Mississippi and denying Terra’s motion to enjoin permanently MCC from proceeding in its own lawsuit subsequently filed in the Mississippi court.
Terra Int’l, Inc. v. Mississippi Chem. Corp.,
I.
Terra International, Inc., manufactures and distributes a variety of agricultural products including nitrogen-based fertilizers. Terra’s principal place of business is in Sioux City, Iowa. Mississippi Chemical Corporation also engages in the production of fertilizers and is the largest manufacturer of ammonium nitrate fertilizer in the United States. MCC’s principal place of business is in Yazoo City, Mississippi.
In the late 1970s, MCC developed an improved ammonium neutralization process and designed a new version of an apparatus called a “neutralizer” which, working together, reduced the ammonium nitrate emissions into the environment and increased the efficiency of the ammonium nitrate manufacturing process. MCC decided to make its neutralizer technology available to the rest of the fertilizer industry by licensing its technology to other fertilizer producers. On April 28, 1980, MCC and Terra entered into a license agreement under which Terra agreed to pay MCC $40,000 to use MCC’s neutralizer technology at Terra’s manufacturing facility in Port Neal, Iowa. 2 The license agreement required MCC to provide Terra with the blueprints to its neutralizer, to review Terra’s proposed design of a neutralizer, and to provide training and start-up engineering assistance to Terra. 3
One section of the license agreement, entitled “Laws and Suits,” contained a forum selection clause. The entire paragraph reads as follows:
This agreement will be construed in accordance with the laws of the State of Mississippi. Any dispute or disputes arising between the parties hereunder, insofar as the same cannot be settled by friendly agreement, will be determined in the District Court of the United States for the Southern District of Mississippi and, for the purpose of instituting such suit, [Terra] hereby consents to service in connection therewith through the Secretary of State for the State of Mississippi.
(Appellant’s App. at A261 (emphasis added).) The emphasized portion of the above paragraph is the forum selection clause at issue in this case, the meaning of which is highly contested.
On December 13, 1994,14 years after Terra and MCC entered into the license agreement, an explosion occurred at Terra’s Port Neal factory. The explosion killed 4 people, injured 18 others, and leveled the facility’s ammonium nitrate plant.
On August 31, 1995, Terra filed a lawsuit against MCC in the United States District Court for the Northern District of Iowa, Western Division, located in Sioux City. In its complaint, Terra limited its cause of action to two tort claims. The first count alleged that MCC negligently designed its neutralizer technology and failed to train and properly warn Terra employees regarding the technology. The second count asserted that MCC’s neutralizer technology was unreasonably dangerous and defective and thus alleged that MCC should be held strictly liable for the damages caused by the explosion. Terra did not assert any parallel claims for breach of contract. On the same day, a few hours later, MCC filed a lawsuit against Terra in the United States District Court for the Southern District of Mississippi, located in Jackson. In its complaint, MCC sought a declaratory judgment that it was not liable in any way for the explosion at Terra’s Port Neal facility and asserted a defamation claim against Terra. 4
In December 1995, MCC filed a motion to transfer the Iowa case to Mississippi pursuant to 28 U.S.C. § 1404(a), while Terra filed a motion for a permanent injunction asking the federal court in Iowa to prevent MCC from prosecuting MCC’s lawsuit in Mississip

After considering many of the relevant factors under section 1404(a), the Iowa court determined that neither the “convenience” factors nor the “interest of justice” factors decidedly weighed in favor of either Iowa or Mississippi.

Section 1404(a) governs the ability of a federal district court to transfer a case to another district. This provision reads: “For the convenience of the parties and witnesses, in the interest of justice, a district court may transfer any civil action to any other district or division where it might have been brought.” 28 U.S.C. § 1404(a) (1994). The statutory language reveals three general categories of factors that courts must consider when deciding a motion to transfer: (1) the convenience of the parties, (2) the convenience of the witnesses, and (3) the interests of justice.
Id.
Courts have not, however, limited a district court’s evaluation of a transfer motion to these enumerated factors. Instead, courts have recognized that such determinations require a case-by-case evaluation of the particular circumstances at hand and a consideration of all relevant factors.
See Stewart Org., Inc. v. Ricoh Corp.,
Although the parties agree that we review a district court’s decision regarding a section 1404(a) transfer motion for an abuse of discretion,
see Stewart,
In
Sun World Lines v. March Shipping Corp.,
Here, interpreting the language of the forum selection clause is necessary to the section 1404(a) transfer analysis. Before a district court can even consider a forum selection clause in its transfer analysis, it first must decide whether the clause applies to the type of claims asserted in the lawsuit. Following the Ninth Circuit’s approach, as well as our own standard of review in cases of contract interpretation,
see United States v. Brekke,
A.
Terra claims that the forum selection clause in the license agreement does not apply to its tort claims and therefore should not receive any consideration in the transfer analysis under section 1404(a). To reiterate, the forum selection clause provides, “Any dispute or disputes arising between the parties hereunder, insofar as the same cannot be settled by friendly agreement, will be determined in the District Court of the United States for the Southern District of Mississippi....” (Appellant’s App. at A261.) Terra contends that the word “hereunder” modifies the word “arising” instead of the word “parties,” indicating that the clause applies only to claims arising under the license agreement. Terra asserts that its tort claims do not arise under the agreement but are independent of it. The district court rejected Terra’s interpretation and emphasized that the placement of “hereunder” directly after “parties” unambiguously indicates that “hereunder” modifies “parties.”
Terra,
After analyzing the language of the clause and reviewing the arguments of the parties, we conclude that the forum selection clause is reasonably susceptible to both interpretations. The placement of “hereunder” directly after the word “parties” could reasonably suggest that it modifies “parties,” which would give the clause a very broad scope covering any disputes arising between the parties. We also find Terra’s interpretation reasonable, because we are persuaded that, at least in this contractual context, “hereunder” typically signifies “under the agreement,” while “hereto” most often refers to the parties to the agreement. Thus, we find that the clause is ambiguous.
See Wilson v. Prudential Ins. Co. Am.,
Terra urges us to construe the ambiguous clause against its drafter' — MCC. We decline to apply the doctrine of
contra proferentem
to this case due to the relatively equal bargaining strengths of both parties and the fact that Terra was represented by sophisticated legal counsel during the formation of the license agreement.

Gen. Corp. v. Grumman Sys. Support Corp.,
‘Whether tort claims are to be governed by forum selection provisions depends upon the intention of the parties reflected in the wording of particular clauses and the facts of each ease.”
Berrett v. Life Ins. Co. of the Southwest,
Although the cases deciding whether very similarly-worded forum selection clauses cover tort claims have reached different conclusions, the majority of these cases suggests that such clauses do apply to tort claims. In
Banco Popular de Puerto Rico v. Airborne Group PLC,
Although determining the scope of a forum selection clause is a rather case-specific exercise, several courts have offered further guidance on this issue and have articulated variously phrased general rules regarding the circumstances in which a forum selection clause will apply to tort claims. The Third Circuit has indicated that where tort claims “ultimately depend on the existence of a contractual relationship” between the parties, such claims are covered by a contractually-based forum selection clause.
Coastal Steel Corp. v. Tilghman Wheelabrator Ltd,.,
The first two guiding principles are not very instructive when applied to the facts of this case. At first glance it appears that Terra’s tort claims would not be covered by the forum selection clause under the Ninth Circuit’s test because the resolution of these products liability claims does not seem to relate to or require the interpretation of the license agreement. Nevertheless, while these tort claims do not center around a disagreement over the specific terms of the license agreement, one could argue that they “relate” to the agreement’s interpretation because the tort claims directly involve the entire subject matter of the license agreement. The Third Circuit’s rale is also inconclusive in this case. MCC asserts that Terra’s tort claims do ultimately depend on the existence of a contractual relationship be *695 cause without the license agreement, MCC would not have provided Terra with its neutralizer technology. Terra, however, argues forcefully that its tort claims are based on MCC’s alleged breach of its common law tort duties which are independent of the contract.
The First Circuit’s approach is more revealing in this case, and we believe that it merits application to the circumstances before us. We think it is clear that Terra’s tort claims involve the same operative facts as would a parallel claim for breach of contract. Admittedly, Terra did not raise any claims for breach of contract in its complaint. Strategic or artfully drawn pleadings, however, will not work to circumvent an otherwise applicable forum selection clause.
See Lambert,
Several other considerations also persuade us that the forum selection clause covers Terra’s tort claims. After finalizing the license agreement, we believe that both parties could have anticipated that tort claims such as Terra now brings would be litigated in Mississippi. Paragraph 2(b) of the license agreement provides that MCC will reimburse Terra for costs or damages resulting from “any defect in the design of [Terra’s] neutralizer ... which can be shown to result from errors in the information contained in the Design Manual.” (Appellant’s App. at A255.) Although Terra contends that this provision is very limited in scope, it expressly envisions that future claims of defective design may arise between the parties. Moreover, Terra’s own complaint repeatedly refers to the specific promises that MCC made under the license agreement. (Id. at A18.) These facts support our conclusion that Terra’s tort claims arise under the license agreement, and therefore, the forum selection clause applies to Terra’s claims. 9
B.
Our conclusion that the scope of the forum selection clause covers Terra’s tort claims does not end our analysis, however. As mentioned earlier, the significance of the forum selection clause in this case arises in the context of a motion to transfer under section 1404(a). The fact that we have found the clause applicable merely allows us to consider it as one factor, albeit a very important one, in the overall transfer analysis. Terra posits the alternative argument that even if the forum selection clause applies, the other relevant factors, especially the convenience of the witnesses, weigh decidedly in favor of the Iowa forum and sufficiently outweigh the significance of the forum selection clause. Terra argues that the district court abused its discretion in evaluating these additional factors and in concluding that they do not weigh in favor of either Iowa or Mississippi, thus giving the forum selection clause dispositive effect in this case.
Terra alleges that the district court abused its discretion in conducting the general section 1404(a) transfer analysis. Initially, Terra argues that the district court improperly shifted the burden of persuasion from MCC to Terra. In general, federal courts give considerable deference to a plaintiffs choice of forum and thus the party seeking a transfer under section 1404(a) typically bears the burden of proving that a transfer is warranted.
See Jumara,
Terra next contends that the district court improperly analyzed the section 1404(a) factors by focusing on whether the inconvenience of litigating in Mississippi could be mitigated instead of determining, on balance, which forum would be the most convenient. Terra primarily challenges the district court’s conclusion that the other relevant factors did not weigh decidedly in favor of the Iowa forum. After reviewing the district court’s reasoning, we find that the district court did not abuse its discretion in weighing the factors relevant to a motion to transfer under section 1404(a).
As mentioned earlier, a transfer motion requires the court to consider the convenience of the parties, the convenience of the witnesses, the interests of justice, and any other relevant factors when comparing alternative venues.
See
28 U.S.C. § 1404(a); 15 Wright, Miller, and Cooper,
supra,
§ 3847. A review of the district court’s opinion reveals that the court meticulously analyzed the numerous criteria that courts traditionally consider when deciding a motion to transfer. Under the general category titled “Balance of Convenience” the district court considered (1) the convenience of the parties, (2) the convenience of the witnesses— including the willingness of witnesses to appear, the ability to subpoena witnesses, and the adequacy of deposition testimony, (3) the accessibility to records and documents, (4) the location where the conduct complained of occurred, and (5) the applicability of each forum state’s substantive law.
Terra,
Although Terra concedes that the district court considered the appropriate factors, Terra focuses its attack primarily on the district court’s analysis regarding the convenience of the witnesses. Terra argues that this factor is significant and weighs heavily in favor of the Iowa forum. Terra explains that a clear majority of nonparty witnesses resides in Iowa, that Terra would not be able to compel these witnesses to
testify
in Mississippi, and that videotaped depositions are a poor substitute for live testimony. While these assertions may be true, we agree with the district court’s conclusion that “sheer numbers of witnesses will not decide which way the convenience factor tips.”
Terra,
To Terra’s credit, we admittedly are quite skeptical of the district court’s conclusion that the balance of convenience was fiat. Even if we tend to believe that the convenience factors weigh in favor of an Iowa forum, however, we cannot say that they so overwhelmingly favor Iowa as to outweigh the significance of the agreed-upon forum selection clause and moreover, to such a degree that the district court abused its discretion in concluding that a transfer was warranted.

To reiterate, a forum selection clause is “a significant factor that figures centrally in the district court’s calculus” in a motion to transfer,

Consequently, we affirm the judgment of the district court. 12 We deny as moot MCC’s motion to supplement the record on appeal.
Notes
. The Honorable Mark W. Bennett, United States District Judge for the Northern District of Iowa.
. MCC's technology is currently used at 22 other ammonium nitrate manufacturing facilities.
. MCC does not actually manufacture neutralizers but merely licenses its neutralizer design to its licensees.
.MCC based its defamation claim on several public statements made by Terra officials in which they asserted that MCC’s defectively designed neutralizer caused the explosion.
. Terra also filed its own motion to transfer in the federal district court in Mississippi, asking the Mississippi court to transfer MCC’s lawsuit to Iowa. In an unreported decision, the federal magistrate judge denied Terra’s motion to transfer, finding that the forum selection clause unambiguously required these disputes to be litigated in Mississippi.
Mississippi Chem. Corp. v. Terra Int’l Inc.,
. Recognizing that its interpretation of the forum selection clause was very broad, the district court attempted to confine the breadth of the clause not by its own terms, but by policy considerations that indicate that it would be unreasonable to apply a broad forum selection clause contained in a contract to a lawsuit that is completely unrelated to the subject of the contract. Consequently, the district court imposed the requirement that the claims at issue between the parties must be sufficiently related to the contract in order for the forum selection clause to apply.
See Terra,
. See, e.g., License Agreement, ¶ 10 ("[njeither party hereto will assign any of its rights or obligations hereunder to any person, firm, corporation or organization not a party to this Agreement without the prior written consent of the other party.”) (Appellant's App. at A261 (emphasis added)); License Agreement, ¶ 12(b) ("The headings contained in this Agreement are used solely for convenience and do not constitute a part of the Agreement between the parties hereto.") (Id. (emphasis added)).
. Having found the clause ambiguous, we appropriately consider extrinsic evidence to interpret this contract provision.
See Marren v. Mutual Life Ins. Co. of New York,
. Our references to portions of the License Agreement that refer to possible design defects merely bolster our belief that the forum selection clause applies to Terra's common law tort claims. We express no views regarding the applicability of any other provision (including any provision for the limitation of liability or damages) of the License Agreement to Terra's tort claims.
. In
The Bremen v. Zapata Off-Shore Co.,
. The district court in Mississippi reached this very conclusion. Unlike the Iowa district court, the Mississippi court believed that the convenience factors favored Iowa but determined that the forum selection clause outweighed these considerations.
See Mississippi Chem. Corp.,
. In the district court, Terra initially argued that because it filed its lawsuit in Iowa a few hours before MCC filed its lawsuit in Mississippi, the first-filed rule dictates that this litigation should proceed in Iowa.
