delivered the Opinion of the Court.
¶1 On November 30, 1999, Michelle Benoit (“Benoit”) pled guilty in the Montana Eighth Judicial District Court, Cascade County, to the charge of felony theft. Benoit was sentenced to a six year deferred imposition of sentence subject, in part, to the condition that she pay restitution in the amount of $15,933.90. Benoit appeals both the restitution order and the length of her sentence. We affirm.
¶2 The following issues are presented for our review:
¶3 1. Whether the District Court erred in ordering Benoit to pay restitution in the amount of $15,933.90?
¶4 2. Whether the District Court violated Benoit’s due process rights under Article II, Section 17, of the Montana Constitution by deferring imposition of her sentence for six years to allow payment of restitution?
FACTUAL AND PROCEDURAL BACKGROUND
¶5 Benoit was employed by Burger Master in Great Falls, Montana, in July 1997. In August 1999, Lynda Monroe (“Monroe”), the general manager of Burger Master, suspected that Benoit was stealing from the business while working at the cash register. Monroe videotaped Benoit for four consecutive days. The videotapes revealed that Benoit was stealing money by falsifying gold card sales. Benoit was observed keying gold card sales into the register when such sales had not actually occurred. Gold cards entitle customers to discounted prices. When a gold card entry is made in the register, the discounted price is automatically deducted from the amount owed by the customer. As a result, Benoit’s customers would pay full price, she would subsequently pocket the difference between the actual price paid and the gold card price discount, and her till would balance properly at the end of the day.
¶6 During the four days Benoit was videotaped falsifying gold card sales, her theft totaled approximately $50.00 to $60.00 each day. After observing the videotapes, Monroe confronted Benoit about the thefts. Thereafter, Benoit signed two statements admitting that she stole money, exceeding $500.00, from Burger Master since the start of her employment. On August 17, 1999, Benoit was arrested after Burger Master notified law enforcement of her acts of theft.
¶7 On August 27, 1999, the Cascade County Attorney filed an Information in the District Court alleging Benoit committed the offense of felony theft, in violation of § 45-6-301(l)(a), MCA (1997), on or between May 1997 and August 1999.
*452¶8 On October 4, 1999, Benoit entered into a non-binding plea agreement with the Cascade County Attorney’s Office. Therein, Benoit agreed to plead guilty to the charge of felony theft in exchange for a recommendation from the Cascade County Attorney that she receive a two year deferred imposition of sentence based upon the possible imposition of various conditions, including the payment of restitution to Burger Master. On November 30,1999, Benoit appeared in District Court and entered a plea of guilty pursuant to the plea agreement. The District Court ordered that a pre-sentence investigation (“PSI”) report be conducted by the Adult Probation and Parole Bureau.
¶9 Patricia Wooldridge (‘Wooldridge”), an Adult Probation and Parole Officer, conducted the PSI and submitted a report to the District Court on March 2, 2000. Wooldridge stated in the PSI that Benoit had no assets and owed approximately $3,105.00 in fines to the Great Falls City Court. In addition, Wooldridge noted that Benoit was unemployed at the time the PSI was conducted, but was seeking employment. Wooldridge further stated that Monroe was in the process of reviewing store records to determine the amount of pecuniary loss sustained by Burger Master and requested additional time to submit a victim impact statement.
¶10 Wooldridge amended the PSI report on March 14,2000, to include a victim impact statement from Monroe, and Monroe’s restitution tabulations for January 1998 through July 1998. Monroe alleged in her statement that Benoit also committed theft by falsifying voided transactions. Monroe explained that Benoit would void a valid transaction and then retain the money paid by the customer. Monroe therefore requested restitution for pecuniary losses sustained by Burger Master resulting from Benoit’s falsification of gold card sales and voided transactions. Based upon Monroe’s examination of Burger Master’s records from January 1998 through July 1998, she calculated an approximate loss of $4,200.00. Monroe, however, noted that her calculation did not include losses sustained from Benoit’s falsified gold card sales between August 1998 to August 1999 or falsified voided transactions. Wooldridge thus recommended in the supplemental PSI that “due to the disparity of the amount first charged and the amounts uncovered with further research, that a separate restitution hearing would be beneficial to the victims, the defendant, and Justice in general.”
¶11 The District Court conducted a combined restitution and sentencing hearing on August 8 and August 22,2000. Monroe testified at the hearing and requested a total amount of $15,933.90 in restitution. Without objection, the State introduced into evidence *453restitution tabulations calculated by Monroe for January 1998 through August 1999.
¶12 Since the specific methods utilized by Monroe in calculating Burger Master’s pecuniary losses are critical to our analysis, we will explain those methods in detail. First, to determine the losses resulting from Benoit’s falsification of voided transactions, Monroe calculated the total number of voided transactions initialed by Benoit during January 1998 through August 1999. Monroe then assumed 25% of Benoit’s voided transactions were legitimate, and thereby subtracted 25% from the total monetary amount of voids conducted by Benoit. The amount totaled $1,833.84.
¶13 Next, Monroe approximated the number of gold card sales Benoit falsified by calculating the total number of gold cards sold by all employees, the total number sold by Benoit, and subtracted the average number of gold cards sold by other employees from the number of gold cards sold by Benoit. Then, Monroe estimated the average monetary amount of each falsified gold card sale by averaging the value of the five different possible gold card item discounts, which ranged in price from $2.50 to $3.25, averaging $3.02 per transaction. Monroe thereafter multiplied the average monetary amount of each gold card sale by the number of estimated sales falsified by Benoit. The amount totaled $12,466.56.
¶14 In addition, Monroe requested restitution for wages paid to three Burger Master employees who assisted in determining restitution by either reviewing records or covering shifts for Monroe and her daughter while they reviewed Burger Master’s records. The wages paid to the three employees totaled $1,633.50. Monroe did not document or request restitution for her own time examining Burger Master’s records.
¶15 Brian Loucks (“Loucks”), a certified public accountant, testified at the restitution hearing on behalf of Benoit. Loucks alleged that Monroe’s assumptions regarding the average value per gold card sale, the number of falsified gold card sales, and the number of falsified voids performed by Benoit were speculative and could alter the amount of actual losses sustained by Burger Master, possibly higher or lower than that calculated by Monroe. He suggested several variables which could be further explored to compile restitution differently, but acknowledged that there is “some guess work” associated with determining losses sustained from employee theft. Loucks, however, did not examine Burger Master’s original records nor did he find such a review necessary, as he disputed only the assumptions made by Monroe.
*454¶16 Benoit also testified at the restitution hearing. She admitted that she stole money from Burger Master by falsifying voided transactions and gold card sales since 1998. She further admitted that she was uncertain of the exact amount she stole from Burger Master. Benoit stated that she was employed and her take home pay ranged from $197.00 to $227.00 per week. She listed her various monthly expenses. In addition, Benoit acknowledged that two years would not give her enough time to pay restitution in the amount of $15,933.90.
¶17 At the conclusion of the hearing, the District Court sentenced Benoit to a six year deferred imposition of sentence subject, in part, to the condition that she pay restitution in the amount of $ 15,933.90. The District Court provided Benoit with the opportunity to withdraw her plea of guilty after two years from the date of entry of its judgment if she satisfied all the conditions imposed therein within that time period. On October 20, 2000, the District Court entered its Judgment of Conviction and Sentencing Order. Benoit appeals.
STANDARD OF REVIEW

¶19 Our review of constitutional questions is plenary. Pritchett, ¶ 27 (citation omitted).
DISCUSSION ISSUE ONE
¶20 Whether the District Court erred in ordering Benoit to pay restitution in the amount of $15,933.90?
¶21 Benoit’s argument is twofold. First, Benoit claims the District Court imposed restitution in violation of § 46-18-242, MCA, since documentation of the victim’s pecuniary loss was not provided in the PSI or to the court at the restitution hearing. Secondly, Benoit contends that Monroe’s restitution calculations were speculative, and therefore the District Court had no authority to impose restitution for amounts which Monroe could only speculate had occurred through acts of theft. Benoit points out that Monroe examined Burger Master’s financial statements daily for the time period in question and never noticed anything that caused her concern prior to August 1999. Benoit alleges the court thus ordered her to pay restitution which was not part of the theft she was “caught performing.” Benoit asserts this case should be reversed and remanded to the District Court for a *455determination of restitution based on the actual amount of provable losses sustained by Burger Master.
¶22 The State responds that the District Court properly assessed the amount of pecuniary loss sustained by Burger Master. The State asserts the requirements of § 46-18-242, MCA, were complied with since the amended PSI included Monroe’s analysis of Burger Master’s losses resulting from Benoit’s theft for seven months, and Monroe presented further documentation at the restitution hearing for the entire time period losses were sustained. Moreover, the State claims Benoit’s counsel had ample opportunity to examine Monroe’s original records prior to the restitution hearing, but failed to do so. The State further contends the court properly assessed restitution since Burger Master’s pecuniary loss was calculated by reasonable methods. The States notes that pecuniary loss is measured by what a victim could recover against an offender in a civil action pursuant to § 46-18-243(l)(a), MCA. The State thus contends that reasonable methods may be employed to determine restitution in the case at hand since we held inHostetter v. Donlan (1986), 221 Mont. 380,383,719 P.2d 1243,1245, that reasonable methods of calculation are permitted in civil cases if losses cannot be ascertained with certainty.
¶23 We will first address whether the District Court had statutory authority to impose restitution in this case. A sentencing court is required to impose a sentence that includes payment of full restitution whenever the sentencing judge finds that a victim of an offense has sustained a pecuniary loss. See Section 46-18-201(5), MCA (1997). However, a sentencing judge is not authorized to impose a sentence of restitution until the procedures stated in § 46-18-241, MCA (1997), through § 46-18-249, MCA (1997), are satisfied. See Section 46-18-201(5), MCA (1997). Also see Pritchett, ¶ 7 (citation omitted). Particularly relevant to the case at hand is whether the court complied with the procedures specified in § 46-18-242, MCA (1997).
¶24 Section 46-18-242, MCA (1997), provides:
Investigation and report of victim’s loss. (1) Whenever the court believes that a victim of the offense may have sustained a pecuniary loss as a result of the offense or whenever the prosecuting attorney requests, the court shall order the probation officer, restitution officer, or other designated person to include in the presentence investigation and report:
(a) documentation of the offender’s financial resources and future ability to pay restitution; and
(b) documentation of the victim’s pecuniary loss, submitted by the victim or by the board of crime control if compensation for the *456victim’s loss has been reimbursed by the crime victims compensation and assistance account.
(2) When a presentence report is not authorized or requested, the court may receive evidence of the offender’s ability to pay and the victim’s loss at the time of sentencing.
¶25 We have held that the failure of a PSI to document a victim’s pecuniary loss, the offender’s financial resources and future ability to pay restitution renders a district court’s judgment illegal, as it violates the requirements of § 46-18-242, MCA(1997). See State v. Muhammad, 2002 MT 47, ¶ 47, 309 Mont. 1, ¶ 47, 43 P.3d 318, ¶ 47 (citing Pritchett, ¶ 13). Here, however, the supplemental PSI included Monroe’s tabulations of pecuniary loss sustained by Burger Master from January 1998 through July 1998. Moreover, Wooldridge noted in the supplemental PSI that an evidentiary hearing should be conducted by the court to determine the total amount of loss sustained by Burger Master. The District Court conducted a combined restitution and sentencing hearing, providing both Benoit and the State with the opportunity to present evidence and cross-examine witnesses. At the hearing, Monroe presented evidence, including her tabulations from January 1998 through August 1999, of pecuniary losses sustained by Burger Master. Further, Benoit’s financial resources were documented in the PSI, and she testified at the sentencing hearing regarding her financial resources and future ability to pay restitution. Consequently, we conclude that documentation of Burger Master’s losses, Benoit’s financial resources and her future ability to pay restitution were presented to the District Court in compliance with § 46-18-242, MCA (1997). Therefore, we hold that the District Court had authority to impose restitution.
¶26 Next, we will examine whether the District Court’s calculation of pecuniary loss sustained by Burger Master is within parameters provided by statute. Section 46-18-243(1), MCA (1997), defines pecuniary loss as follows:
(a) all special damages, but not general damages, substantiated by evidence in the record, that a person could recover against the offender in a civil action arising out of the facts or events constituting the offender’s criminal activities, including without limitation the money equivalent of loss resulting from property taken, destroyed, broken, or otherwise harmed and out-of-pocket losses, such as medical expenses, loss of income, expenses reasonably incurred in obtaining ordinary and necessary services that the victim would have performed if not injured, expenses reasonably incurred in attending court proceedings related to the *457commission of the offense ...
(b) reasonable out-of-pocket expenses incurred by the victim in filing charges or in cooperating in the investigation and prosecution of the offense. [Emphasis added.]
¶27 We have held that a criminal defendant is liable for restitution for offenses to which the defendant has admitted, as a defendant is required to make full restitution for pecuniary losses “arising out of the facts or events constituting the offender’s criminal activities,” pursuant to § 46-18-241(1), MCA (1997), and § 46-18-243(l)(a), MCA (1997). See State v. Beavers, 2000 MT 145, ¶ 11, 300 Mont. 49, ¶ 11, 3 P.3d 614, ¶ 11. Also see State v. Korang (1989), 237 Mont. 390, 395-397, 773 P.2d 326, 329-330 (holding that the court did not err in ordering the offender to make full restitution for losses sustained from a time period not alleged in the charging information since the evidence presented at the sentencing hearing established the losses sustained by the victim during that time period arose out of the facts or events constituting the offender’s criminal activities).
¶28 Here, the charging information alleged Benoit committed felony theft at Burger Master from May 1997 through August 1999. On November 30, 1999, Benoit pled guilty to the charge of felony theft. Additionally, Benoit admitted at the restitution hearing that she committed theft at Burger Master by falsifying gold card sales and voided transactions since 1998. Consequently, we conclude that Benoit is liable for pecuniary losses sustained by Burger Master resulting from her admitted acts of theft from January 1998 through August 1999.
¶29 We will now turn our attention to whether the methods utilized by Monroe in calculating restitution, and subsequently adopted by the court, are within statutory mandates. As the State correctly points out, the amount of pecuniary loss recoverable by Burger Master is measured by the amount of loss recoverable in a civil action. See Section 46-18-243(l)(a), MCA (1997). We have held that an award of speculative damages is not allowed in civil cases. See Stensvad v. Miners and Merchants Bank of Roundup (1982), 196 Mont. 193, 206, 640 P.2d 1303, 1310 (citation omitted). However, we have held that loss of future profits, although often speculative, are recoverable “[o]nce liability is shown, that is the certainty that the damages are caused by the breach, then loss of profits on a reasonable basis for computation and the best evidence available under the circumstances will support a reasonably close estimate of the loss by a District Court.” See Hostetter, 221 Mont. at 382-383, 719 P.2d at 1245 (quoting Stensvad, 196 Mont. at 206, 640 P.2d at 1310). Consequently, *458we hold that the losses sustained from Benoit’s admitted acts of theft are recoverable, even though the actual losses may be uncertain, if the losses were calculated by use of reasonable methods based on the best evidence available under the circumstances.
¶30 The evidence presented at the hearing in this case establishes that actual losses resulting from Benoit’s theft could not be determined with certainty. As a result, Monroe made several assumptions to determine restitution. Benoit’s witness, Loucks, disputed the assumptions made by Monroe and suggested several variables which could be further explored to compile restitution, but he acknowledged that there is often “some guess work” associated with determining losses sustained from employee theft. Loucks further acknowledged that implementation of such variables could alter the amount of restitution calculated by Monroe to Benoit’s detriment. Moreover, Benoit did not provide the court with a reasonable estimation of the losses sustained by Burger Master. Therefore, we conclude that the methods utilized by Monroe and subsequently adopted by the court were reasonable based on the best evidence available under the circumstances presented in this case.
¶31 We further conclude that Burger Master may recover reasonable out-of-pocket expenses incurred in cooperating in the investigation and prosecution of this case, which are substantiated by the evidence in the record, pursuant to § 46-18-243(l)(b), MCA (1997). Since the record demonstrates that Burger Master incurred out-of-pocket expenses when it paid wages to three employees who assisted, directly and indirectly, in calculating restitution, Burger Master is entitled to such losses. We therefore conclude that the District Court did not exceed its statutory authority when it ordered Benoit to pay restitution in the amount of $15,933.90. Consequently, we affirm the District Court’s restitution order.
ISSUE TWO
¶32 Whether the District Court violated Benoit’s due process rights under Article II, Section 17, of the Montana Constitution by deferring imposition of her sentence for six years to allow payment of restitution?
¶33 Relying on our decision in Pritchett, ¶ 37 (citing State v. Farrell (1984), 207 Mont. 483, 676 P.2d 168), Benoit argues the District Court violated her due process rights under Article II, Section 17, of the Montana Constitution when it increased her deferred imposition of sentence from two years, as recommended in the plea agreement, to the maximum allowable deferment period of six years to insure *459payment of restitution. Benoit asserts her sentence should be reversed and remanded for determination of a length of sentence consistent with her charge and her history instead of her ability to pay restitution.
¶34 In opposition, the State points out that the facts stated in Farrell and Pritchett are distinguishable from this case since the maximum allowable punishment was not imposed in this case. Rather, the District Court deferred imposition of Benoit’s sentence for the maximum allowable period in accordance with § 46-18-201(l)(a)(ii), MCA, which specifically authorizes a deferment for six years “if a financial obligation is imposed as a condition of sentence[.]” The State thus contends the length of Benoit’s deferred imposition of sentence was appropriate. We agree.
¶35 Article II, Section 17, of the Montana Constitution provides that: “No person shall be deprived of life, liberty, or property without due process of law.” We have held that a criminal defendant’s right to due process requires that “indigency or poverty not be used as the touchstone for imposing the maximum allowable punishment.” Pritchett, ¶ 28 (quoting Farrell, 207 Mont. at 499, 676 P.2d at 177).
¶36 The defendant in Pritchett pled guilty to burglary and was sentenced to the maximum allowable punishment of twenty years, all of which was suspended based upon the condition that he pay restitution. Pritchett, ¶ 26. Since the court sentenced Pritchett to the maximum term based on his indigency, we held that the court violated the defendant’s right to due process. Pritchett, ¶ 37. Likewise, we held in Farrell that the court violated the defendant’s due process rights when it based the length of his sentence on his indigency and sentenced him to the maximum allowable punishment of ten years for the offense of theft, all suspended subject to the condition that he make full restitution. Farrell, 207 Mont. at 498-499, 676 P.2d at 176-177.
¶37 Here, however, Benoit was not sentenced to the maximum allowable punishment of ten years for the offense of felony theft. See Section 45-6-301(7), MCA (1997). Rather, the court imposed a six year deferred imposition of sentence, the maximum allowable period a sentence may be deferred if restitution is imposed as a condition of the sentence pursuant to § 46-18-201(l)(a)(ii), MCA (1997). Therefore, we conclude that the facts presented in Pritchett and Farrell are distinguishable from the facts in the case at hand.
¶38 Further, the District Court provided Benoit the opportunity to withdraw her plea of guilty prior to the termination of the six year deferred imposition of sentence. Specifically, the District Court stated *460that “[a]t any time after a period of two years from the date of this Order, if the Defendant can show that she has satisfied all conditions of this Order, the Court will consider an early request to withdraw her plea of guilty.” For the foregoing reasons, we conclude that the District Court did not violate Benoit’s due process rights guaranteed by Article II, Section 17, of the Montana Constitution. Accordingly, we affirm the length of Benoit’s deferred imposition of sentence.
¶39 Affirmed.
CHIEF JUSTICE GRAY, JUSTICES NELSON and LEAPHART concur.
