While shopping at Wal-Mart, Mary Garcia, sole owner of a small business, was knocked to the floor by a Wal-Mart employee pushing a cart. She brought a diversity suit against Wal-Mart Stores, Inc. (“Wal-Mart”) in federal district court, alleging negligence, and the jury awarded her damages. We must determine whether the district court erred in declining to instruct the jury on the issues of mitigation and apportionment of damages and in failing to award Garcia “actual costs” pursuant to a Colorado cost-shifting statute, Colo.Rev.Stat. § 13-17-202(1)(a)(I) (1999). We exercise jurisdiction pursuant to 28 U.S.C. § 1291 and affirm the jury’s verdict, concluding Wal-Mart failed to object in timely fashion to the omission of the mitigation instruction and the district court properly decided there was no “competent evidence” to support the apportionment instruction. However, applying the Eñe doctrine, we hold that Colorado’s cost-shifting statute applies and remand to the district court for the determination of “actual costs” and the award of those costs to Garcia.
I
On January 25, 1995, appellee/cross-appellant Garcia and her husband went shopping at Wal-Mart. While Garcia searched for film in one of the aisles, she was hit by a cart pushed by a Wal-Mart employee and knocked to the floor, hurting her back, which had already been causing her pain before the incident. Several physicians and one psychologist, each after having examined her once, determined that a portion of her back pain may have been psychological or “non-organic” in nature, i.e., not a direct result of her physiological condition. Most of them, however, did not deny that at the same time she might be suffering physical pain caused by her physical injury. Her treating physicians also testified that Garcia suffered from chronic degenerative disc disease prior to the incident at Wal-Mart.
Before she was hit, Garcia owned and operated “Mary’s Burritos.” Rising between 4:30 and 5:00 a.m. on weekday mornings, she would prepare, by 8:00 a.m., between twelve and eighteen dozen burritos, weighing almost forty pounds, load them into a cooler, and deliver them to local businesses. After the incident at Wal-Mart, she found herself physically unable to lift the cooler and found it very difficult to get into and out of her car. That physical incapacitation rendered her unable to continue operating her business, which she turned over to her sister-in-law, Valerie Gonzales.
An economist estimated her economic losses from her inability to pursue her business to be between approximately $631,000 and $908,000 — the former figure based in part on Garcia’s loss of earnings from her business, and the latter figure based in part on average earnings of someone of her age and education level. There was also testimony on the value of her business, the degree of her disability with regard to physical functioning and performance of household chores, and her projected yearly medical expenses.
*1173 At trial, Wal-Mart submitted proposed jury instructions on both mitigation of damages by Garcia and apportionment of damages contingent on the jury’s ability to separate out the portion of Garcia’s damages attributable to pre-existing conditions. After the close of argument, the district court furnished the parties with the set of instructions it intended to submit to the jury, admonishing them to review those instructions. The district court did not instruct on mitigation of damages, and Wal-Mart did not object to that omission before the jury retired to consider its verdict.
The district court also did not give the portion of Wal-Mart’s proposed apportionment of damages instruction-which stated,
If you are able to separate the amount of damages, if any, caused by the negligence of the Defendant from the amount of damages, if any, caused by the ailment or disability which existed before January 25, 1995, then the Plaintiff is entitled to recover damages caused only by the negligence of the Defendant.
If you are unable to separate the damages caused by the ailment or disability which existed before January 25, 1995, and the damage caused by the negligence of the Defendant, then the Defendant is legally responsible for the entire amount of damages you find the Plaintiff has incurred.
(Appellant’s App. at 48.) Wal-Mart’s counsel thrice argued that an apportionment instruction was warranted, first stating “there was evidence of the apportionment issue through the deposition of Dr. Wong” (Appellant’s App. at 190), an orthopedic surgeon, then stating that the testimony of Dr. Quintero, a neurologist, “addressed [the] issue [of apportionment] by indicating that the only problem was liga-mentous strain ... [and][a]nything after that was not caused by this incident” (id. at 229), and finally reiterating those arguments on the morning before the court instructed the jury. After each suggestion by Wal-Mart that an apportionment instruction be included, the court indicated it did not find the evidence sufficient to support an apportionment instruction.
The jury awarded damages to Garcia in the amount of $75,000 for non-economic losses, $268,000 for economic losses, and $7,000 for physical impairment or disfigurement, for a total award of $350,000. The trial court further awarded prejudgment interest in the amount of $110,100, an amount to which the parties stipulated, and litigation costs in the amount of $2,236.90 pursuant to 28 U.S.C. § 1920, but denied Garcia’s actual costs under Colo.Rev.Stat. 13-17-202(l)(a)(I) (1999), which provides for the taxation of costs based on Wal-Mart’s pretrial rejection of a settlement offer lower than the eventual judgment. 1 Wal-Mart appeals from the jury verdict, and Garcia cross-appeals, claiming an additional $18,952.50 in “actual” litigation costs pursuant to the foregoing statute.

“We review the district court’s decision to give a particular jury instruction for abuse of discretion and consider the instructions as a whole de novo to determine whether they accurately informed the jury of the governing law.”
United States v. Cerrato-Reyes,
*1174 A
Because Wal-Mart did not object to the court’s failure to give the mitigation of damages instruction before the jury retired, and because the absence of such an instruction did not result in a fundamental injustice, we reject Wal-Mart’s claim that the district court erred by not instructing on mitigation. Fed.R.Civ.P. 51 unequivocally provides that “[n]o party may assign as error the giving or the failure to give an instruction unless the party objects thereto before the jury retires to consider its verdict, stating distinctly the matter objected to and the grounds of the objection.” This Court articulated the policy behind the rule in
Medlock v. Ortho Biotech, Inc.,
Absent a proper objection, we apply the plain error standard of review. But “[o]nly rarely will we reverse based on allegedly erroneous instructions to which there was no objection at trial; the party claiming plain error has the heavy burden of demonstrating fundamental injustice.”
Medlock,
We discern no “fundamental injustice” in the district court’s failure to submit a mitigation instruction to the jury in this case.
Medlock,
The same can be said of Wal-Mart’s assertion that Garcia failed to mitigate the economic consequences of her injury by failing to get help in operating Mary’s Burritos. The court found Garcia’s business was “almost a personal service business that only she could do” and implicitly that efforts to employ others to continue operating the business would be futile and therefore not reasonable mitigation.
(Id.
at 255.) In addition, Wal-Mart offered no evidence that appropriate jobs were available for someone in Garcia’s condition or that such jobs were available to someone of her educational and skill level, but instead merely presented the evidence of its medical expert that she could return to sedentary light-duty or self-paced jobs.
See Wilson v. Union Pacific R.R. Co.

We must also determine whether it was error for the district court to refuse Wal-Mart’s proposed instruction that the jury apportion, if possible, Garcia’s disability between its negligence and her preexisting condition. Colorado law provides that when a defendant can demonstrate that a separable portion of a plaintiffs disability is traceable to a pre-existing condition, the defendant is hable for only that portion caused by his or her negligence.
See, e.g. Stephens v. Koch,
As evidence supporting an apportionment instruction, Wal-Mart points to the statements of two physicians. However, although Dr. David Wong, an orthopedic surgeon, stated in a deposition that he thought “the underlying difficulty was [Garcia’s] sprain or strain from the accident superimposed on some degenerative changes in the spine which were preexisting,” (Appellant’s App. at 178), Wal-Mart offers no Colorado case law indicating such a general statement is sufficient to allow a jury to find that Wal-Mart has borne its burden of showing the separation between pre-existing disability and disability resulting from the defendant’s negligence,
see Stephens,
In deciding not to issue the proposed instruction, the judge declared, “I don’t see how apportionment is possible in this case.”
(Id.
at 232.) Given the paucity of evidence indicating how such apportion
*1176
ment might function, it was not an abuse of discretion for the court to determine that an apportionment instruction was inappropriate; and omission of Wal-Mart’s urged instruction did not result in a failure to inform the jury accurately of the governing law.
See Newbury v. Vogel,
Ill
Our resolution of Garcia’s cross-claim of error by the district court for failing to award “actual costs” pursuant to Colo.Rev.Stat. § 13-17-202(1)(a)(I) is guided by
Trierweiler v. Croxton & Trench Holding Corp.,
where a federal rule of procedure is directly on point, that rule applies. Otherwise, in the “typical, relatively unguided Erie choice,” courts are to heed the outcome-determination approach while also relying on the policies underlying the Erie rule: “discouragement of forum-shopping and avoidance of inequitable administration of the laws.”
Id.
at 1539 (quoting
Hanna v. Plumer,
Applying the
TrienveilerHanna
analysis to the inquiry as to the subject matter of Colo.Rev.Stat. § 13-17-202(1)(a)(I), neither Fed.R.Civ.P. 68 nor 54(d) are “directly on point.”
Trierweiler,
In the case of Fed.R.Civ.P. 54(d)(2), involving “attorneys’ fees and related non-taxable expenses,” the Rule expressly refers to “the substantive law governing the action,” i.e., the governing state law in a diversity action.
See id.
The provision “gives effect to the ‘American Rule’ that each party must bear its own attorneys’ fees in the absence of a rule, statute or contract authorizing such an award.”
MRO Communications, Inc, v. AT&T Co.,
To the extent Congress has not spoken to the specific costs Garcia claims under Fed.R.Civ.P. 54(d)(1), and to the extent, if at all, her “actual costs” may be “related non-taxable expenses” under Fed.R.Civ.P. 54(d)(2), we are squarely in the realm of the “typical, relatively unguided
Erie
choice.”
Hanna,
Chaparral Resources, Inc. v. Monsanto Co.,
In the present case, on the contrary, Colorado courts have interpreted Colo.Rev.Stat. § 13-17-202(1)(a)(I) to be non-discretionary: If a defendant refuses a plaintiffs offer of settlement made more than ten days before trial, and at trial the plaintiff recovers an amount greater than the settlement offer, then "the plaintiff shall be awarded actual costs accruing after the offer of the settlement to be paid by the defendant." See also Centric-Jones Co. v. Hufnagei
IV
The decision of the district court is AFFIRMED in part, REVERSED in part, and REMANDED to the district court to determine and award “actual costs” to Garcia in accordance with this opinion.
Notes
. Colo.Rev.Stat. § 13-17-202 (1999) provides as follows:
(l)(a) Notwithstanding any other statute to the contrary, in any civil action of any nature commenced or appealed in any court of record in this state:
(I) If the plaintiff serves an offer of settlement at any time more than ten days before the commencement of the trial that is rejected by the defendant and the plaintiff recovers a final judgment in excess of the amount offered, then the plaintiff shall be awarded actual costs accruing after the offer of the settlement to be paid by the defendant.
. Wal-Mart cites
Monsma v. Central Mutual Insurance Co.,
The Ninth Circuit’s decision in
Monsma
does not stand for the proposition appellant urges. In that case, the district court intended to give a tendered jury instruction and so informed counsel, afterwards inadvertently omitting the instruction.
Monsma,
. Fed.RXiv.P. 68 provides in relevant part as follows:
Offer of Judgment. At any time more than 10 days before the trial begins, a party defending against a claim may serve upon the adverse party an offer to allow judgment to be taken against the defending party for the money or property or to the effect specified in the offer, with costs then accrued.... If the judgment finally obtained by the offeree is not more favorable than the offer, the offeree must pay the costs incurred after the making of the offer....
. Fed.R.Civ.P. 54(d) provides in relevant part as follows:
Costs; Attorneys' Fees.
(1) Costs Other than Attorneys' Fees. Except when express provision therefor is made either in a statute of the United States or in these rules, costs other than attorneys' fees shall be allowed as of course to the prevailing party unless the court otherwise directs; but costs against the United States, its officers, and agencies shall be imposed only to the extent permitted by law. Such costs may be taxed by the clerk on one day’s notice. On motion served within 5 days thereafter, the action of the clerk may be reviewed by the court.
(2) Attorneys' Fees.
(A) Claims for attorneys’ fees and related non-taxable expenses shall be made by motion unless the substantive law governing the action provides for the recovery of such fees as an element of damages to be proved at trial.
. Appellants cite
Crawford Fitting Co. v. J.T. Gibbons, Inc.,
. We note that Colo.Rev.Stat. § 13 — 17— 202(l)(b) expressly excludes attorneys’ fees from the definition of "actual costs.” We leave to the district court the determination of what "actual costs,” if any, under Colo.Rev. Stat. § 13-17-202(1)(a)(I) may qualify as "related non-taxable expenses” under Fed. R.Civ.P. 54(d)(2).
. We note, however, that although the award of actual costs is non-discretionary, the trial court retains discretion over the amount of actual costs awarded. See Scholz v. Metropolitan Pathologists, P.C.,
. With respect to explicit federal statutory provisions under Rule 54(d)(l), Chaparral dealt with the comprehensive witness fee scheme of 28 U.S.C. § 1821. see Crawford,
. The record before us on appeal does not indicate the precise nature of the "actual costs" claimed. We therefore leave to the district court the correct application of the *1179 Colorado statute — read in conjunction with Fed.R.Civ.P. 54(d) and the relevant federal statutes — to the particular costs claimed in this case.
