OPINION
TOMLJANOVICH, Justice.Following a finding that appellant Commonwealth Land Title Insurance Company (Commonwealth) violated the Minnesota Human Rights Act (MHRA), Minn.Stat. § 363.03, subd. 1 (1992), the trial court awarded respondent Geraldine Phelps compensatory damages in an amount twice that of the actual damages established at trial pursuant to Minn.Stat. § 363.071, subd. 2 (1992). On appeal to this court, Commonwealth contends the court of appeals erred by finding that the trial court acted within its discretion in doubling the amount of actual damages pursuant to Minn.Stat. § 363.071, subd. 2. We reject Commonwealth’s contentions and affirm.
On October 25,1993, following a trial without a jury, the trial court concluded that Commonwealth discriminated against Phelps on the basis of age and disability. The trial court determined Phelps presented evidence of actual damages totaling $80,382.33. Relying on Minn.Stat. § 363.071, subd. 2, the trial court then multiplied this figure by two and awarded Phelps $160,764.66 as compensatory damages. The trial court did not provide any findings supporting its decision to double the actual damages. Additionally, the trial court awarded Phelps $75,000 for mental anguish and suffering and $42,491.99 for attorney fees and costs. Finally, the trial court awarded the statutory maximum of $8,500 for punitive damages.
On appeal, the court of appeals rejected Commonwealth’s argument that the trial court abused its discretion by doubling the actual damages, holding:
[T]he district court acted within its discretion in doubling Phelps’ compensatory damages, even though the court did not specifically find that Phelps would not be adequately compensated by an award of actual damages.
Phelps v. Commonwealth Land Title Ins. Co., 520 N.W.2d 748, 752 (Minn.App.1994). In dicta the court of appeals also stated:
Were we to require that multiple damages be tied to uncompensated damages, we would still affirm the district court’s multiplication of damages in the present case. Phelps persuasively argues that the following losses would have remained uncompensated by an unaugmented award of compensatory damages: loss of her pension, loss of potential raises, loss of dental insurance, and loss of some medical insurance. Phelps also asserts that her inability to maintain payments on her residence after she was discharged from Commonwealth required her to move and deprived her of the continuity of home and community.
Id.
On appeal to this court, Commonwealth contends the court of appeals’ conclusion in dicta was erroneous because Phelps did not present any evidence of the losses the court of appeals outlined in dicta. We conclude that the court of appeals did err, however, this was an error in dicta. As such, the existence of this error is irrelevant to the resolution of this case. Commonwealth also renews its argument that the trial court abused its discretion by doubling the actual damages under Minn.Stat. § 363.071, subd. 2.
Minnesota Statutes § 363.071, subd. 2 provides in relevant part:
In all cases where the administrative law judge1 finds that the respondent has engaged in an unfair discriminatory practice, the administrative law judge shall order the respondent to pay an aggrieved party, who has suffered discrimination, compensatory damages in an amount up to three times the actual damages sustained. In all cases, the administrative law judge may *274also order the respondent to pay an aggrieved party, who has suffered discrimination, damages for mental anguish or suffering and reasonable attorney’s fees, in addition to punitive damages in an amount not more than $8,500.
(emphasis added). Whether a trial court properly doubled the actual damages under Minn.Stat. § 363.071, subd. 2 is reviewed under an abuse of discretion standard. Melsha v. Wickes Cos., 459 N.W.2d 707, 709 (Minn.App.1990), pet. for rev. denied, (Minn. Oct. 25, 1990). Commonwealth claims the trial court abused its discretion and makes five arguments in favor of reversal. In addition, Commonwealth argues that inclusion of back pay in the amount the trial court" doubled constitutes error.
I.
First, Commonwealth claims the court of appeals’ determination that the trial court’s multiplication of damages was valid is inconsistent with legislative intent. If a statute is ambiguous, a court may refer to the legislative history surrounding the statute’s enactment to ascertain its legislative intent. Minn.Stat. § 645.16(7) (1994). Where the intention of the legislature is clearly manifested by plain unambiguous language, however, no construction is necessary or permitted. Lenz v. Coon Creek Watershed Dist., 278 Minn. 1, 9, 153 N.W.2d 209, 216 (1967). Thus, prior to consideration of legislative history, a determination that subdivision 2 is ambiguous is necessary.
A statute is ambiguous if it is susceptible to more than one reasonable interpretation. Glen Paul Court Neighborhood Ass’n v. Paster, 437 N.W.2d 52, 56 (Minn.1989); Tuma v. Commissioner of Economic Sec., 386 N.W.2d 702, 706 (Minn.1986) (citing Beck v. City of St. Paul, 304 Minn. 438, 445, 231 N.W.2d 919, 923 (1975)); Arcadia Dev. Corp. v. County of Hennepin, 528 N.W.2d 857, 860 (Minn.1995), reh’g denied (Minn. Apr. 12, 1995). Commonwealth does not contend that subdivision 2 is susceptible to more than one interpretation. Instead, Commonwealth contends subdivision 2 “is ambiguous because it provides absolutely no guidance to trial courts in determining when compensatory damages must be multiplied.” This court, in a slightly different context, has said that failure of expression does not give rise to ambiguity. See State v. Moseng, 254 Minn. 263, 269, 95 N.W.2d 6, 11-12 (1959) (holding “[w]here failure of expression rather than ambiguity of expression concerning the elements of the statutory standard is the vice of the enactment, courts are not free to substitute amendment for construction and thereby supply the omissions of the legislature.”); see also State v. Wetsch, 511 N.W.2d 490, 492 (Minn.App.1994) (stating “[although [appellant] disagrees with the legislative decision to make failure to provide proof of insurance a strict liability offense while including a scien-ter requirement for failure to provide insurance, his disagreement does not make [the statute] ambiguous”), pet. for rev. denied (Minn. Apr. 19, 1994).
Subdivision 2 contains no guidelines as to when or under what circumstances a trial court may multiply damages. The absence of guidelines or restraints on a trial court’s discretion to multiply damages does not make subdivision 2 ambiguous. In the absence of such guidelines, this court should not manufacture them, that is the province of the legislature. Accordingly, we decline to read into subdivision 2 restrictions or guidelines that the legislature has not included. Instead, we conclude subdivision 2 unambiguously vests trial courts with the discretion to multiply damages.
II.
Commonwealth next argues that the trial court’s award is inconsistent with standards articulated by other courts. Having found that subdivision 2 vests the trial court with the discretion to multiply actual damages in an amount up to three times the amount of damages proven at trial, we believe this argument is rendered moot. To the extent that other decisions impose restraints on a trial court’s discretion to multiply damages under subdivision 2, these decisions are erroneous. We comment here on at least two decisions that are impacted by our holding today.
*275In Melsha v. Wickes Cos., the court of appeals interpreted subdivision 2 and concluded:
It is within the discretion of the trial court to determine whether, in the interests of justice, the actual damages must be multiplied in order for a victim to be fully compensated.
459 N.W.2d at 709. In addition, the Minnesota federal district court, quoting Melsha, has held:
Multiplied damages are permitted so as to provide victims of discrimination with ‘full and adequate compensation’ in cases when the amount of actual damages proved do not alone achieve that result.
Baufield v. Safelite Glass Corp., 831 F.Supp. 713, 720 (D.Minn.1993) (quoting Melsha, 459 N.W.2d at 709).
Commonwealth contends that based on Melsha, a trial court must tie the multiplication of damages to a finding that the victim was not fully compensated. Based on our conclusion that subdivision 2 unambiguously vests a trial court with discretion to multiply damages, we further conclude that after an initial finding of damages, a trial court need not make an additional finding that uncompensated damages exist prior to multiplying damages pursuant to Minn.Stat. § 363.071, subd. 2. Thus, Commonwealth’s contention that a trial court must tie the multiplication of damages to a finding of uncompensated damages is erroneous, and to the extent that Melsha and Baufield support this contention, they too are erroneous.
The dissent finds it problematic for a trial court to multiply actual damages beyond those proven at trial without a specific finding that uncompensated damages exist.
As the dissent points out, compensatory damages are generally understood to be those damages for which a person has actual losses. However, it is equally well settled that the phrase “actual damages” is generally regarded as a synonym for compensatory damages. Black’s Law Dictionary 390 (6th ed.1990). Thus, this court is left to discern what the legislature intends when it states: “a trial court shall award compensatory damages up to three times the amount of actual damages.” The dissent concludes that this means the trial court may multiply actual damages only if the trial court makes a finding that uncompensated damages exist. We believe that in the context of this statute, this construction is unsupported by the language of the statute, and could lead to absurd results in practice.
In the absence of a statute defining compensatory damages, it is clear that compensatory damages are generally synonymous with actual damages. However, when the legislature has stepped in and defined the elements of damage that will consist of compensatory damage, we believe that the legislature’s directive governs. For example, in the context of the Uniform Commercial Code, the legislature has limited compensatory damages to compensation. See Minn.Stat. § 336.1-106 (1994) code comment (stating “compensatory damages are limited to compensation. They do not include * * * special damages * ⅜ * ”).2 Similarly, we believe, that in this case, the legislature has defined compensatory damages to be an amount up to three times the actual damages proven.
In addition, in practice, the dissent’s construction of subdivision 2, tying multiple damages to a finding of uncompensated damages leads to one of two results, both of which are impractical. One possible result would be that a trial court would never be in a position to award uncompensated damages because the actual damages would reflect the sum of the amount a person has lost, thus, there would be no additional damages that could be compensated. In that case, a court could award multiple damages only if it made up damages not alleged or proven at trial. This is precisely the type of sua sponte fact finding in which the court of appeals in dicta engaged that we reject. The other possible result of adopting the dissent’s construction is that it would provide an incentive to plain*276tiff’s counsel to be sloppy in presenting damages evidence or, worse yet, to lay in the weeds deliberately withholding the evidence and later argue the need for multiplied damages to compensate for all of the uncompensated items.
Each of the potential results illustrates that the dissent’s construction could lead to absurd or unreasonable results that would, in effect, render the multiplier provision meaningless. A presumption exists against statutory constructions that lead to absurd or unreasonable results. Minn.Stat. § 645.17(1) (1994). In accordance with well settled statutory construction, therefore, we believe the legislature intended the trial court to be able to multiply at its discretion.
III.
Third, Commonwealth contends the trial court’s failure to make findings in support of its award of multiple damages is an abuse of discretion. It further claims that this failure and the court of appeals’ holding that findings are unnecessary are both inconsistent with Sigurdson v. Isanti County where this court stated:
Because of the significance of factual issues in employment discrimination cases and the attendant deference that must be accorded trial courts in making their determinations on these issues, it is important that the basis for the court’s decision be set forth clearly and explicitly so that an appellate court can conduct effective and meaningful review.
386 N.W.2d 715, 721 (Minn.1986).
This quote reflects the Sigurdson court’s frustration with a trial court that had failed to make detailed findings in relation to its application of the three-part test articulated in McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973). Under the McDonnell Douglas test, for a trial court to conclude that discrimination occurred, the court must make findings as to each part of the test. In contrast, subdivision 2 does not require a trial court to make any findings prior to multiplying damages. If the legislature had said damages may be trebled only if the trier of fact determines that actual damages are nominal or uncompensated damages exist, then failure by the trial court to make findings prior to multiplying damages would be error. However, since the legislature has not made findings of any sort a requirement, we conclude that no findings are necessary to support a trial court’s decision to multiply damages.
IV.
Fourth, Commonwealth and Amici3 contend that the trial court’s award of both punitive damages and double actual damages constituted an unfair double recovery for punitive damages. In support of this contention, Commonwealth cites Johnson v. Jensen, 446 N.W.2d 664 (Minn.1989) and Amici cite Fontaine v. Ebtec Corp., 415 Mass. 809, 613 N.E.2d 881 (1993). In both cases the respective supreme courts determined that an award of punitive damages and multiple actual damages were duplicative.
Johnson and Fontaine are distinguishable from the present case. Under the statute at issue in Fontaine, damages could only be multiplied upon a finding of a “knowing or reckless statutory violation.” 613 N.E.2d at 889. And under the statute at issue in Johnson, damages could only be trebled if the destruction of the trees was not casual or unknowing. 446 N.W.2d at 665. Under both statutes, the findings necessary to multiply damages were similar to the finding of willfulness necessary for the imposition of punitive damages at that time. See Minn.Stat. § 549.20, subd. 1 (1988) (stating that punitive damages shall be allowed upon a showing of willful indifference). Thus, an award under these statutes of multiplied damages and punitive damages was essentially a double recovery for punitive damages. By contrast, subdivision 2 requires no additional showing for the imposition of multiple damages. Thus, these cases are distinguishable from the present case.
*277In addition, although it is unclear what damages are being compensated by the multiple damages provision, that fact alone does not necessarily make the provision punitive and thus duplicative of punitive damages. See DeJonghe v. E.F. Hutton & Co., 171 Ariz. 341, 830 P.2d 862, 866 (App.1991) (“[w]e view this [provision] as akin to the antitrust remedy of treble damages, which is intended not only to compensate for losses and to deter from misconduct but also to encourage private litigants to supplement official enforcement of important criminal laws by providing an inducement for such action.”), pet. for rev. denied, (Ariz. June 16, 1992). Legislative history indicates that one objective the legislature sought to achieve through enactment of subdivision 2 was the enticement of the private bar into bringing claims based on violations of the MHRA.4 We conclude, therefore, that multiple compensatory damages are not duplicative of punitive damages where at least one objective of multiple compensatory damages is nonpunitive. Thus, the trial court’s award of both punitive damages and double actual damages does not constitute an unfair double recovery for punitive damages.
The dissent believes that any multiplication without a specific finding must necessarily be punitive. We believe that the language of subdivision 2 and other courts’ construction of that language indicates that multiple damages are distinct from punitive damages. Subdivision 2 specifically identifies the multiplied damages as compensatory and later indicates punitive damages may also be awarded. As the federal district court of Minnesota noted, although the trebling function in this statute has a deterrent effect, it is primarily a compensatory measure which is made all the more clear by the statute’s explicit labeling of the treble damages as “compensatory.” Evans v. Ford Motor Co., 768 F.Supp. 1318, 1327 (D.Minn.1991) (stating multiple damages under subdivision 2 “are compensatory in nature”); see Convent of the Visitation Sch. v. Continental Casualty Co., 707 F.Supp. 412, 416 (D.Minn.1989). Thus, by virtue of the statute’s language, and as other courts have found, the legislature seemed to intend the multiplying provision to have some other function distinct from punitive damages.
V.
Commonwealth next asserts a constitutional challenge to subdivision 2. This challenge was not raised at the trial court or the court of appeals. We generally decline to review the constitutionality of a statute if it has not been previously raised. Charboneau v. American Family Ins. Co., 481 N.W.2d 19, 23 (Minn.1992); Egeland v. State, 408 N.W.2d 848, 852 (Minn.1987); In re C.L.L., 310 N.W.2d 555, 557 (Minn.1981). In Cohen v. Cowles Media, Co., however, we indicated that “on rare occasions [we have] exercised our discretion to allow a party to proceed on a theory not raised at trial.” 479 N.W.2d 387, 390 (Minn.1992), remanded on reh’g, 481 N.W.2d 840 (Minn. Mar. 17, 1992). We conclude that this is not one of those rare occasions, and decline to consider the constitutionality of subdivision 2.
VI.
Finally, Commonwealth contends that the trial court erroneously included Phelps’ back pay award as part of the amount it doubled. Minnesota Statutes § 363.071, subd. 2 provides in relevant part:
In all cases where the administrative law judge finds that the. respondent has engaged in an unfair discriminatory practice, the administrative law judge shall order the respondent to pay an aggrieved party, who has suffered discrimination, compensatory damages in an amount up to three times the actual damages sustained. *278* * *. In addition to the aforesaid remedies, in a case involving discrimination in
(a) employment, the administrative law judge may order the hiring, reinstatement or upgrading of an aggrieved party, who has suffered discrimination, with or without back pay, * * *.
Commonwealth claims that under the statute back pay is not an element of compensatory damages and thus, should not be included in the calculations of compensatory damages to be multiplied. We disagree. We do not believe the statute precludes the inclusion of back pay as an element of damages that is subject to multiplication. The statute gives a trial court the option of including back pay as a part of actual damages subject to multiplication, or merely awarding back pay attendant to the hiring, reinstatement, or upgrading of an aggrieved party. Thus, we conclude the trial court did not err by including back pay in the amount of actual damages that were subsequently multiplied.
