In this contractual indemnification case, appellant Asplundh Tree Expert Company (“Asplundh”) appeals the district court’s grant of summary judgment to Union Pacific Railroad Company (“Union Pacific”) on Union Pacific’s claim that it was indemnified by Asplundh for injuries sustained by Union Pacific employee Terry Neustrom (“Neus-trom”) and the district court’s order for As-plundh to reimburse Union Pacific for its settlement with Neustrom. Asplundh also appeals the district court’s order that As-plundh pay pre-judgment interest, Union Pacific’s costs, and attorneys’ fees. We affirm all of the district court’s ruhngs with the exception of the grant of attorneys’ fees, which we vacate and remand for a finding of reasonableness.
Background
In 1987, Union Pacific and Asplundh entered into a contract under which Asplundh agreed to spray chemical defoliants along Union Pacific’s “Central Region” railroad lines. Under the agreement, Union Pacific was required to provide a spraying train as well as “personnel to supervise the movement of contract spray equipment over its lines.” The actual spraying of defoliant was conducted by Asplundh personnel from a spraying car owned by Asplundh, employing equipment operated and supervised by As-plundh personnel.
On June 27, 1991, defoliant spraying was scheduled along the main line tracks between *1061 Junction City and Salina, Kansas. The only person on the spraying train that day licensed to spray chemicals was Asplundh spray supervisor Charles Shetron (“She-tron”). In order for the spray train to leave the Junction City train yard and make its way onto the main track, it was necessary for someone to line and reline some track switches. Neustrom, a brakeman employed by Union Pacific, was assigned this job. After switching the tracks, Neustrom approached the train to get back on it, only to find himself engulfed in defoliant. He experienced burning in his throat, tightness in his chest, and difficulty breathing. Neustrom was subsequently diagnosed as suffering from Reactive Airway Dysfunction Syndrome (RADS) and underwent a lengthy series of treatments for that disorder.
Neustrom sued Union Pacific under the Federal Employer’s Liability Act (FELA), 45 U.S.C. § 51 et seq., for failing to provide him with a safe working environment. In his complaint, Neustrom alleged that Union Pacific and Asplundh negligently caused his injuries, and asked for one million dollars in damages. After Asplundh refused Union Pacific’s tender to take over defense of the suit, Union Pacific filed a Third Party Complaint against Asplundh based on the indemnity provision of the contract. That provision read, in its entirety:
The Contractor [Asplundh] shall indemnify and hold harmless the Railroad Company [Union Pacific], its affiliates, their officers, agents, employees, against and from any and all liability, loss, damage, claims, demands, costs and expenses of whatsoever nature, including court costs and attorneys’ fees, arising from or growing out of any injury to or death of persons whomsoever (including officers, agents and employees of the Railroad Company, of the Contractor and of any subcontractor, as well as other persons) or loss of or damage to property whatsoever (including property of or in custody of the Railroad Company, the Contractor or any subcontractor as well as other property). The right to indemnify shall accrue when such injury, death, loss or damage occurs from any cause and is associated in whole or in part with the work performed under this agreement, a breach of the agreement or the failure to observe the health and safety provisions of the agreement or any activity or omission arising out of performance or nonperformance of this agreement. However, the Contractor shall not indemnify the Railroad Company when the loss is caused by the sole negligence of the Railroad Company.
To the extent that it lawfully may do so, the Contractor waives any and all defenses under workers’ compensation or industrial insurance acts to so indemnify the Railroad Company.
Union Pacific moved for summary judgment against Asplundh, seeking indemnification from Asplundh for Neustrom’s claims against Union Pacific under the contract. The district court granted Union Pacific’s motion. Thereafter, Union Pacific entered into settlement negotiations with Neustrom and tendered defense of Neustrom’s claim to Asplundh; Asplundh failed to take up that defense. Union Pacific settled with Neus-trom for $65,000, and filed a Motion to Assess Judgment against Asplundh with the district court. The district court found in favor of Union Pacific, and assessed As-plundh the entire $65,000, plus Union Pacific’s attorneys’ fees and costs, as well as prejudgment interest on both the settlement amount and Union Pacific’s attorneys’ fees and costs incurred up to October 1, 1995, for a total of $177,182.96.
In this consolidated appeal, Asplundh appeals the district court’s judgments against it and moves to certify two questions to the Supreme Court of Kansas: (1) whether as a matter of Kansas law Asplundh agreed to indemnify Union Pacific for Union Pacific’s joint negligence; and (2) if so, whether such an agreement violates Kansas public policy and is void on that ground.
Discussion
I. The Indemnification Agreement
A. Jurisdiction, Standard of Review, and Choice of Law
The district court had jurisdiction over Neustrom’s FELA claim under 28
*1062
U.S.C. § 1331 (federal question jurisdiction) and over the contractual indemnification issue under 28 U.S.C. § 1367 (supplemental jurisdiction). This court has jurisdiction under 28 U.S.C. § 1291. We review grants of summary judgment de novo.
See Kaul v. Stephan,
B. The Contractual Language
Asplundh argues that the language of this indemnification provision is unclear and over broad, and thus cannot support an interpretation that Asplundh agreed to indemnify Union Pacific for its own negligence. Union Pacific responds that the language in the indemnification provision is capable of only one reading: that Asplundh agreed to indemnify Union Pacific for all claims arising out of the spraying operations, including those arising in part from Union Pacific’s own negligence, excepting only those claims based solely on Union Pacific’s negligence.
Under Kansas law, agreements in which one party agrees to indemnify another for the indemnitee’s own negligence are disfavored and as such must be expressed in “clear and unequivocal language.”
Zenda Grain & Supply Co. v. Farmland Indus., Inc.,
“The policy of the law in general is to permit mentally competent parties to arrange their own contracts and fashion their own remedies where no fraud or overreaching is practiced. Contracts freely arrived at and fairly made are favorites of the law.”
Kansas City Structural Steel Co. v. L.G. Barcus & Sons, Inc.,
Next we turn to the question of whether the indemnification clause in this contract evinced, in clear and unequivocal language, the intent of the parties that Asplundh indemnify Union Pacific for its own negligence. Although under Kansas law par
*1063
ties may contract for indemnification against their own negligence, “broad and seemingly all-inclusive language” is not sufficient to overcome the judicial disfavor of such agreements.
Zenda Grain,
“The parties agree that if loss or damage should result from the failure of performance or operation or from defective performance or operation or from improper installation or servicing of the [Rollins] System, that Rollins’ liability, if any, for the loss or damage thus sustained shall be limited ... and that the provisions of this paragraph shall apply if loss or damage ... results ... from negligence ... of Rollins, its agents or employees.”

Zenda Grain
the Court of Appeals exhorted “[t]hose drafting hold harmless clauses in the future” to look to the language of
Corral
“and follow it carefully.”
See Zenda Grain,
Here we have a contractual indemnification clause that specifically addresses Union Pacific’s negligence. Asplundh argues that because the term negligence in this clause is modified by the adjective “sole,” it remains ambiguous whether Asplundh agreed to indemnify Union Pacific for any other kind of negligence. As a result, Asplundh claims, we must hold that the indemnification clause fails to evince, in clear and unequivocal terms, an intent on Asplundh’s part to indemnify Union Pacific for joint negligence. We decline Asplundh’s invitation to do so.
Under Kansas law:
Unambiguous contracts are enforced according to their plain, general, and common meaning in order to ensure the intentions of the parties are enforced. The intent of the parties is determined from the four corners of an unambiguous instrument, harmonizing the language therein if possible. Ambiguity does not appear ... [unless it is] genuinely uncertain which of two or more meanings is the proper meaning.
Hall v. JFW, Inc.,
Our holding in this case is supported by our opinion in
Titan Steel Corp. v. Walton,
C. Kansas public policy
Asplundh next argues that even if we find that the indemnification provision does evince a clear intent that Asplundh indemnify Union Pacific for its own joint negligence, we should declare this provision void because it violates Kansas public policy as embodied in Kansas statutes governing railroads. The main thrust of Asplundh’s argument is that allowing a common carrier to enjoy indemnification by third parties for its own negligence is tantamount to giving the carrier a license to kill or maim, and that because of this the Kansas legislature has enacted a statute preventing just such an eventuality.
Asplundh directs our attention to Kan. Stat. Ann. § 66-234, which reads:
Liability for negligence. Railroads in this state shall be liable for all damages done to person or property, when done in consequence of any neglect on the part of the railroad companies.
Asplundh insists that under this statute railroads cannot indemnify themselves for their own negligence, and relies upon
Sewell v. Atchison, T & S.F. Ry. Co.,
In addition to
Sewell,
Asplundh cites two other older Kansas cases, namely
Kansas Pacific Ry. Co. v. Peavey,
The cases of Kansas Pacific Ry. Co. v. Peavey, ... [and] Railway Co. v. Fronk, ... are not in point, for the reason that they all involved liability for injuries to employés, and it was held that because of the interest which the state has in the *1065 lives, health, and safety of its citizens, the state may intervene in such contracts in the interest of the public welfare, and that contracts with an employe exempting the company from liability for injuries resulting from the neglect of the company’s agents is void as against public policy....
Griffiths Grain Co. v. St. Joseph & G.I. Ry. Co.,
Indeed, in
Anderson v. Union Pacific R.R. Co.,
D. Certification of Asplundh’s Questions
Asplundh urges us to certify to the Supreme Court of Kansas the questions of whether the indemnification clause here clearly and unequivocally expressed the parties’ intent for Asplundh to indemnify Union Pacific for its own negligence, and whether such an indemnification of a railroad violates Kansas public policy. It is well-established law in this circuit that “[e]ertification is particularly appropriate where the legal question at issue is novel and the applicable state law is unsettled.”
Allstate Ins. Co. v. Brown,
II. Summary Judgment
Asplundh next argues that even assuming that the indemnification agreement was clear and unequivocal and not violative *1066 of Kansas public policy, the district court nonetheless erred in granting Union Pacific summary judgment because controverted material facts remained. The material facts that Asplundh alleges were controverted at the time of the court’s ruling include: (1) whether Union Pacific was solely negligent in causing Neustrom’s injury and therefore not entitled to indemnification under the contract; (2) whether Neustrom was actually injured by the spray; and (3) whether Neus-trom was completely at fault for being in the vicinity of the spray.
“Only disputes over facts that might affect the outcome of the suit under the governing law will properly preclude the entry of summary judgment.”
Anderson v. Liberty Lobby, Inc.,
The indemnification agreement before us covers “any and all liability, loss, damages, claims, demands, costs and expenses of whatsoever nature” excepting, of course, when the claim is based upon Union Pacific’s sole negligence. It is uncontested that Neustrom brought a claim against Union Pacific, and that Union Pacific chose to settle that claim after offering the defense of that claim to Asplundh. Thus, the only issue we must address is whether a jury could have found that Union Pacific was solely negligent in causing Neustrom to be sprayed with defoliant.
In its brief on appeal, Asplundh asserts that “all persons” involved in the spraying operation “were responsible for being attentive and watching for potential safety hazards.” Accordingly, Asplundh appears to concede that both Union Pacific and As-plundh personnel had a duty to watch the tracks and remain on the lookout for by-standing personnel. Moreover, Asplundh’s spray operator Shetron testified that he knew there would be a brakeman lining the switch who would have to be positioned near the train. Asplundh admits that its personnel were the only ones on the train who were licensed to handle and apply these chemical defoliants, and that its employees had complete control over the “act of pulling the trigger to distribute the herbicides.” Given the control enjoyed by Asplundh personnel over the release of the chemical spray and the affirmative duty of those personnel to remain on the lookout for bystanders, all of which was freely admitted to this court by Asplundh, if a reasonable jury could find negligence at all, it could not have found Union Pacific solely liable for the spraying of Neustrom. Summary judgment on this issue was proper.
III. The Settlement
After obtaining summary judgment on the issue of indemnification, Union Pacific settled with Neustrom for the sum of $65,-000, and the district court granted Union Pacific’s Motion to Assess Judgment against Asplundh. Asplundh claims that because (1) it had no right or duty under the provisions of the indemnification agreement to defend the suit, and (2) the settlement was not reasonable nor made in good faith, it was error on the part of the district court to grant Union Pacific’s motion.
We first address Asplundh’s assertion that it had no right or duty to take over defense of the suit when so offered by Union Pacific. This claim is controlled by
Missouri Pacific R.R. Co. v. Kansas Gas & Elec. Co.,
Where an indemnitor denies liability and refuses to assume the defense of a claim under a contract of indemnity, the indem-nitee, without waiving its rights [to indemnification], may enter into a good faith, reasonable and prudent settlement with the claimant.
*1067 Id. at 800. Thus, in order to trigger an indemnitor’s duty to cover a settlement, the indemnitee need only show that it was under “potential liability ... and that the settlement amount was reasonably related to its employee’s injuries.” Id. (quotation omitted). Thus, we are left only with the question of whether Union Pacific was subject to “potential liability” when it entered into the settlement with Neustrom and whether the settlement was reasonably related to Neus-trom’s claimed injuries.
Asplundh attacks Union Pacific’s decision to enter into a settlement with Neustrom by rearguing its position that Neustrom had no viable claim. This argument ignores the fact that Union Pacific was at all times subject to potential liability, especially given that the obstacles to recovery facing FELA plaintiffs are much lower than those facing most tort plaintiffs. See id. Union Pacific was clearly under potential liability for this claim.
Next, we must turn to the question of whether the settlement amount was reasonably related to Neustrom’s injuries, as found by the district court. We review this finding of fact by the district court for clear error.
See Hockett v. Sun Co.,
IY. Attorneys’ Fees, Litigation Costs, and Prejudgment Interest
We review the district court’s decision to award prejudgment interest for abuse of discretion.
See Driver Music Co. v. Commercial Union Ins. Cos.,
A claim becomes liquidated when both the amount due and the date on which it is due are fixed and certain, or when the same become definitely ascertainable by mathematical computation. Where an amount is due upon contract, either express or implied, and there is no uncertainty as to the amount which is due or the date on which it becomes due, the creditor is entitled to recover interest from the due date.
Id.
Asplundh first asserts that the district court erred in awarding Union Pacific prejudgment interest on its settlement with Neustrom because that settlement was not liquidated until the court made its determination as to its reasonableness. Union Pacific responds that as of September 26, 1995, the date that Union Pacific settled with Neustrom, the amount of the settlement became liquidated as required by Kansas law.
Once Union Pacific and Neustrom agreed upon a settlement amount, barring a showing that the settlement was not reasonably related to the underlying injury or that it was entered into in bad faith, the settlement amount became liquidated for the purposes of assessing prejudgment interest. As discussed above, Asplundh did not make such a showing. Thus, the district court did not err in awarding Asplundh prejudgment interest on the settlement amount, commencing from the date the settlement became final.
See Missouri Pacific,
As for the attorneys’ fees issue, “[a]lthough generally we review a district court’s award of attorneys’ fees for an abuse of discretion, we review its application of the legal principles underlying the award
de novo.” Towerridge, Inc. v. T.A.O., Inc.,
In
Missouri Pacific,
this court was faced with substantially the same question, i.e., whether a party’s contractual agreement to pay attorneys’ fees for claims “arising out of or connected with” the party’s failure to keep the track clear of obstacles included attorneys’ fees incurred in the course of enforcing the agreement itself.
See Missouri Pacific,
However, we agree with Asplundh that the calculation of the fees and costs cannot stand because of the district court’s failure to make a finding that Union Pacific’s attorney’s fees and costs were reasonable. The district court held that because the indemnification provision does not require that attorneys’ fees be “reasonable,” no such showing was required. To the contrary, under Kansas law, a duty to act reasonably and in good faith must be read into every contract, including the terms of indemnification clauses.
See Hartford v. Tanner,
Conclusion
For the reasons stated above, we AFFIRM the district court’s grant of summary judgment to Union Pacific on the issue of indemnification, we AFFIRM the district court’s assessment against Asplundh for the amount of Union Pacific’s settlement with Neustrom, plus prejudgment interest and costs, and we VACATE and REMAND the award of attorneys’ fees and legal costs with instructions that the district court determine the reasonable costs and attorneys’ fees incurred by Union Pacific. The district court’s order awarding interest on attorneys’ fees, costs, and expenses which were liquidated in amount as of October 1, 1995, is AFFIRMED.
Notes
. Asplundh attempts to argue that Union Pacific's liability to Neustrom was not negligence, hut rather "statutory liability under FELA.” This argument avails Asplundh little, because a FELA action
is
an action for negligence.
See
45 U.S.C. § 51 ("Every common carrier by railroad while engaging in [interstate commerce] ... shall be liable in damages to any person suffering injury while he is employed by such carrier ... for such injury or death
resulting in whole or in part from the negligence
of any of the officers, agents, or employees of such carrier, or
by reason of any defect or insufficiency, due to its negligence,
in its ... equipment.”) (emphasis added);
Metro-North Commuter R.R. Co. v. Buckley,
. Asplundh argues that the “clear and unequivocal term” requirement may have different meanings in different jurisdictions. However, As-plundh does not provide any authority for the proposition that the requirement differs between the slates of Kansas and Utah. To the contrary, we have previously applied the general standards articulated in
Titan Steel
to a question involving an indemnification clause in a contract governed by Kansas law.
See Kansas City Power & Light Co. v. United Tel. Co.,
. Asplundh also quotes from two passages in American Jurisprudence as support for its position that railroads and other common carriers may not contract their negligence liability away to third parties. See Am.Jur.2d Indemnity § 10 (1995); 14 Am.Jur.2d Carriers § 554 (1964). However, American Jurisprudence is a general compilation of cases. In this case, we are guided by specific Kansas case law.
