In this diversity action for breach of contract and vexatious refusal to pay an insurance claim, Bluewood, Inc. appeals *800 the judgment of the district court 1 entered on a jury verdict against the Cincinnati Insurance Company (“Cincinnati”). Although the jury found in favor of Blue-wood, it did not award any damages beyond the $93,283 that Cincinnati had already paid on Bluewood’s insurance claim. For the following reasons, we affirm.
I. BACKGROUND
Bluewood is the self-described “managing agent” of the Broadmoor apartment complex in Jefferson City, Missouri, and the beneficiary of an insurance policy issued by Cincinnati that covered Broadm-oor against enumerated losses, including certain types of water damage. On the morning of December 27, 2004, James Cain and Steve Sweeten, the two-person maintenance staff at Broadmoor, learned that water was running under the door of a ground-level apartment in “Building C.” Upon opening the door, Cain and Sweeten saw water falling from the ceiling and running down the walls. At least four inches of water had accumulated on the floor. Cain and Sweeten shut off the water and electricity to Building C, whose eight units were vacant, and proceeded to check the building’s other seven apartments. Later that day, Cain and Sweeten discovered a similar problem in “Building B,” which had five vacant units and three units with tenants who had left their apartments unattended from December 25 to December 27.
After Cain and Sweeten located the sources of the leaks — a burst pipe in one of the upper-level apartments in each building — they started to execute an improvised plan to dry the apartments. First, Cain and Sweeten used a squeegee to push standing water out the front doors of several apartments. Next, Cain and Sweeten removed the carpets and underlay pads in the apartments that had been saturated with water. This task occupied much of Cain and Sweeten’s time for at least four days and perhaps as long as a week. During that period, a member of Broadmoor’s staff rented six fans and at least one dehumidifier, which Cain and Sweeten used in the wet apartments on a rotating basis. In addition, Cain and Sweeten attempted to accelerate the drying process by cycling each apartment’s heating and air conditioning units and opening windows when weather conditions seemed favorable. Eventually, Cain and Sweeten noticed mold growing in some of the apartments that had been exposed to water.
Neither Cain nor Sweeten had any experience or expertise in the field of water removal — or what both parties sometimes refer to as “water remediation.” Yet in the weeks that followed this incident, Blue-wood did not hire a water-remediation professional to assist Cain and Sweeten.
In late December or early January, John Morrissey, Bluewood’s president, called John Rowe, the insurance agent who sold Bluewood the Cincinnati policy that covered Broadmoor. While the substance of this conversation is disputed, its result is clear: Rowe did not contact Cincinnati to file a claim at that time. On January 27, 2005, a representative from Bluewood’s “home office” in St. Louis visited Broadm-oor to inspect the damage to Buildings B and C. The next day, Rowe submitted a loss notice form to Cincinnati, thereby indicating that Bluewood intended to file a claim.
Cincinnati and Bluewood each hired insurance adjusters to estimate the value of *801 the loss in terms of the cost to remediate or replace the damaged property within Buildings B and C at Broadmoor. Cincinnati’s adjuster reached an estimate of $93,191.83, excluding the cost of mold remediation, which Cincinnati insisted was not covered under the policy. Bluewood’s adjuster reached an estimate of $536,138.20, which included the cost of at least some mold remediation. These competing estimates reflected differences in the adjusters’ conclusions about the extent of the damage as well as a broader disagreement between Cincinnati and Blue-wood over the question whether Bluewood complied with its contractual obligation to mitigate its damages.
Cincinnati paid Bluewood $93,283. Shortly thereafter, Bluewood exercised its right under the policy to demand an appraisal of the loss. Although Cincinnati and Bluewood each selected one of the two appraisers, who then agreed on an umpire, Bluewood objected to Cincinnati’s proposed “Agreement for Submission to Appraisal.” In turn, Cincinnati filed this action in federal court, seeking a declaration that the policy’s appraisal provision allowed Cincinnati to deny Bluewood’s claim for additional damages, notwithstanding the result of the proposed appraisal. Bluewood raised five counterclaims, asserting, among other things, that Cincinnati had breached its contractual obligations and that Cincinnati’s refusal to pay Blue-wood’s insurance claim was vexatious and unreasonable. When the parties agreed that their central dispute was over the amount of damages, the district court decided to treat the case as a diversity action for breach of contract and vexatious refusal to pay an insurance claim. In effect, Bluewood became the plaintiff and Cincinnati the defendant.
After a five-day trial held in September 2007, the jury returned a verdict in favor of Bluewood, but it did not award any damages beyond the $93,283 that Cincinnati had already paid. The district court denied Bluewood’s motion for a new trial. Bluewood appeals, asking this court to vacate the judgment and remand the case for further proceedings.
II. DISCUSSION
Bluewood’s primary argument on appeal is that the district court applied the wrong measure of damages to the loss at Broadmoor. According to Bluewood, the district court’s error caused it to deliver a defective instruction to the jury and to improperly exclude expert testimony from one of Bluewood’s proposed witnesses.
We typically review a district court’s rulings concerning contested jury instructions for abuse of discretion.
Bass v. Flying J, Inc.,
The parties agree that Missouri law governs this case; thus, we consider the Missouri Supreme Court’s interpretation of Missouri law to be authoritative.
See St. Paul Fire & Marine Ins. Co. v. Schrum,
Under Missouri law, if an insurance policy is unambiguous, it will be “enforced as written,” unless a statute or public policy requires a different result.
Peters v. Employers Mut. Cas. Co.,
If you find in favor of Bluewood, Inc. on its [insurance] claim ... you must award Bluewood, Inc. such sum as you may find from the evidence to be the “actual cash value” of the damaged property.
“Actual cash value” as used in this instruction means the cost to replace the damaged property less a deduction that reflects depreciation, age, condition and obsolescence, if any.
Bluewood contends that the unambiguous terms of the policy should not have been enforced as written because section 379.150 of the Missouri Revised Statutes sets a different measure of damages. Section 379.150 provides:
Whenever there is a partial destruction or damage to property covered by insurance, it shall be the duty of the party writing the policies to pay the assured a sum of money equal to the damage done to the property, or repair the same to the extent of such damage, not exceeding the amount written in the policy, so that said property shall be in as good condition as before the fire, at the option of the insured.
(Emphasis added.) The Missouri Supreme Court has held that the amount of a cash payment “equal to the damage done to the property” is “to be determined by the difference in value of the property immediately before and immediately after the loss.”
Wells v. Mo. Prop. Ins. Placement Facility,
The district court concluded that section 379.150 applies only to cases involving losses caused by fire. As a result, the district court gave Instruction 14, which established that the measure of damages under the policy was the cost to replace the damaged property within Buildings B and C at Broadmoor (less a potential deduction for depreciation, age, condition and obsolescence) rather than the difference in the before-and-after fair market value of the damaged buildings. Over Bluewood’s objection, the district court also excluded expert testimony from David Nunn regarding the fair market value of Broadm-oor before and after the loss. Bluewood maintains that these decisions constituted “prejudicial errors” because the cash-settlement provision of section 379.150 supplies the measure of damages in cases involving losses caused by water or any other covered risk. The Missouri Supreme Court has not announced whether section 379.150 apphes to losses caused by risks other than fire, so we are left to predict how it would resolve this issue.
*803
We begin with the text of the statute.
See State ex rel. Burns v. Whittington,
This argument has some surface appeal, for “[cjanons of construction ordinarily suggest that terms connected by a disjunctive be given separate meanings.”
Reiter v. Sonotone Corp.,
More than any grammatical considerations, the phrase appearing at the end of section 379.150 — “at the option of the insured” — informs the meaning of the statute’s two principal clauses. In this context, “option” implies a
choice
between two forms of compensation: a cash settlement or a course of repairs.
See Wells,
Bluewood argues in the alternative that we should disregard the limiting phrase “as before the fire” in light of the expansion of insurance coverage beyond losses caused by fire that has occurred in the 130 years since section 379.150 was enacted. On this view, both the cash-settlement option and the repair-or-replace option now apply to losses caused by any covered risk. We reject Bluewood’s alternative construction of section 379.150 because it would turn the limiting phrase “as before the fire” into mere surplusage. Notwithstanding the expansion of insurance coverage over the last 130 years, we predict that the
*804
Missouri Supreme Court would decline Bluewood’s invitation to disregard part of the statutory text.
See State ex rel. SSM Health Care St. Louis v. Neill,
The parties identified four decisions in which the Missouri Court of Appeals has mentioned that section 379.150 might extend to losses caused by risks other than fire. In the first of these decisions, the court of appeals noted that the plaintiffs argument — presumably in favor of extending section 379.150 to cases involving wind damage — was “theoretically correct” but ultimately not dispositive because of a failure of proof.
Cady v. Hartford Fire Ins. Co.,
After examining the relevant authorities, we predict that the Missouri Supreme Court would find that section 379.150 applies only to cases involving losses caused by fire. Contrary to Bluewood’s proposed constructions, the most natural reading of section 379.150 holds that the limiting phrase “as before the fire” identifies the one and only type of “partial destruction or damage to property covered by insurance” that triggers the insured’s right to choose between a cash settlement and a course of repairs. This interpretation harmonizes the statute’s two principal clauses and gives meaning to every word of the statutory text. Consequently, we reject Blue-wood’s contention that the district court misinterpreted Missouri law concerning the proper measure of damages in this case. We also reject, without further comment, Bluewood’s derivative arguments that Instruction 14 established the wrong measure of damages and that the district court improperly excluded expert testimony from David Nunn insofar as those arguments are premised on the applicability of section 379.150.
We now address Bluewood’s remaining arguments, starting with Bluewood’s three alternative challenges to Instruction 14. Apart from setting the measure of damages under the policy, Instruction 14 also provided that Bluewood “had a duty under the law to mitigate its damages — that is, to exercise ordinary care under the circumstances to minimize its damages.” Blue-wood’s initial contention is that the district court failed to define the term “ordinary care.” Bluewood next asserts that the district court’s phrasing implied an absolute duty to “abate and stop” the water and mold damage at Broadmoor, even if that *805 was not scientifically possible. Last, Blue-wood argues that the district court’s description of Bluewood’s duty to mitigate its damages gave the jury a “roving commission” to return an unlawful verdict.
To preserve a challenge to an allegedly defective jury instruction, a party must “state distinctly [its] specific objections ... before the jury retires.”
Dupre v. Fru-Con Eng’g Inc.,
Where a challenge has not been adequately preserved, we review the district court’s instruction for plain error.
Id.
at 333 (citing
Rolscreen Co. v. Pella Prods. of St. Louis, Inc.,
The record shows that Bluewood failed to preserve the three alternative challenges to Instruction 14 that it seeks to raise on appeal. On the contrary, Blue-wood objected to Instruction 14 at trial “on the basis that ... the proper measure of damages in this case is [the] fair market value of the property immediately before and immediately after the loss under [section 379.150.” Bluewood also argued that “the use of the term actual cash value ... is misleading and will allow the jury an impermissible roving commission to take into consideration matters such as repair cost, which are not relevant under [Blue-wood’s proposed measure of damages].” The district court overruled Bluewood’s contemporaneous objection based on its finding that Instruction 14 set forth the proper measure of damages under the policy. But the district court was not afforded an opportunity to correct the alleged defects in Instruction 14’s so-called “tail for mitigation” because Bluewood did not specifically object to those provisions. 3 Although Bluewood used the term “roving commission” when it explained the basis for its contemporaneous objection, the substance of that objection has no connection to Bluewood’s arguments on appeal concerning the district court’s description of the mitigation requirement. We therefore review Instruction 14’s mitigation provisions for plain error. 4
*806
Having carefully reviewed Blue-wood’s unpreserved challenges, we conclude that this is not the exceptional case in which an instructional error has “prejudice[d] the substantial rights of a party and would result in a miscarriage of justice if left uncorrected.”
Slidell,
Bluewood’s third challenge is equally lacking in merit, because Instruction 14 did not assume a disputed fact or submit an abstract legal question to the jury.
See Seitz v. Lemay Bank & Trust Co.,
Finally, we turn to Bluewood’s challenges to two of the district court’s
*807
evidentiary rulings, which we review for “a clear and prejudicial abuse of discretion.”
Smith v. Tenet Healthsystem SL, Inc.,
Bluewood does not allege that the district court deviated from the Federal Rules of Evidence by, for example, failing to consider the relevant facts or the parties’ arguments.
See Sprint/United Mgmt. Co. v. Mendelsohn,
— U.S. —,
Bluewood also challenges the district court’s decision to admit expert testimony from Ivan Turner about the growth and remediation of mold. Bluewood argues that the district court should have excluded Turner’s testimony under Rule 702 because Turner lacked the requisite “knowledge, skill, experience, training, or education” to testify about these technical subjects. Moreover, Bluewood claims that Turner’s professed expertise in the fields of water and mold remediation is nothing more than “junk science.”
As Cincinnati points out, Turner testified at length about his knowledge, skill, experience and training in the relevant fields. In particular, Turner testified that
*808
he had received advanced training in methods of “applied structural drying,” that he held certifications from the Institute of Inspection, Cleaning and Restoration and the Indoor Air Quality Association, that he had participated in between 1,500 and 2,000 water remediation jobs over the past 15 years, and that he regularly performs experimental testing related to mold growth and prevention. While Bluewood makes much of the fact that Turner did not attend college, the Supreme Court has made clear that the “test of reliability is ‘flexible,’ ” and it does not necessarily turn on a single factor.
Kumho Tire Co. v. Carmichael,
III. CONCLUSION
For the foregoing reasons, we affirm the judgment of the district court.
Notes
. The Honorable Nanette K. Laughrey, United States District Judge for the Western District of Missouri.
. In a fifth decision, the Missouri Court of Appeals dismissed on procedural grounds an appeal from a grant of summary judgment that was based on the trial court's finding that section 379.150 applied only to "insurance claims arising from damage caused by
fire." Anderson v. Am. Family Mut. Ins. Co.,
. The district court noted, however, that Blue-wood's proposed instructions omitted any variation on the “tail for mitigation” included in Instruction 14. The district court’s unprompted observation appears to be the only reference to the mitigation requirement during the extended colloquy between the district court and both parties about the court's proposed instructions.
. Bluewood conceded at oral argument that its "roving commission” objection did not preserve its challenge to the district court's failure to define the term “ordinary care.” Nonetheless, Bluewood later submitted a letter to inform this court that it raised the other two challenges to Instruction 14’s provisions regarding mitigation in its motion for a new trial. This fact is inapposite, however, since a
*806
party must present its specific objections to an allegedly defective jury instruction
“before
the jury retires.”
Dupre,
. Given Bluewood's failure to show any reasonable likelihood that the district court's alleged instructional errors affected the jury’s verdict, we would reach the same result if we reviewed Instruction 14 under the abuse of discretion standard that applies where a party has preserved an objection for appellate review.
See Green v. City of St. Louis,
. Bluewood argues on appeal that the meaning of replacement cost to a “layperson” is not the "cost to replace” a piece of damaged property, but rather “the current fair market value of the relevant property immediately prior to the loss.” (Emphasis added.) Blue-wood does not offer any support for this facially implausible premise, so we reject its proffered conclusion — that Nunn’s testimony was extremely relevant — without additional analysis. Cf. Webster's Third New International Dictionary 1925 (1986) (defining "replacement cost” as "the current cost of replacing a fixed asset with a new one of equal effectiveness.”).
