Stanley K. JOYNES, III
v.
Maria L. PAYNE.
Record No. 1556-00-2.
Court of Appeals of Virginia, Richmond.
May 8, 2001.
*565 Edward D. Barnes (Charles E. Powers; Barnes & Batzli, P.C., on briefs), Chesterfield, for appellant.
James C. Roberts (Dawn B. DeBoer; Melissa J. Roberts; Mays & Valentine, L.L.P., on brief), Richmond, for appellee.
Present: ELDER, ANNUNZIATA and HUMPHREYS, JJ.
HUMPHREYS, Judge.
Stanley K. Joynes appeals a final decree of divorce in which the circuit court granted his wife, Maria L. Payne, a divorce, granted Payne custody of the parties' two children, distributed the parties' marital property, and granted Payne spousal support, child support, and attorney's fees. Joynes alleges that the trial court erred in: (1) awarding custody of the parties' children to Payne; (2) failing to allow Joynes to present additional evidence after the close of evidence; (3) failing to establish May 28, 1999 as the date of the custody award; (4) awarding the ordered level of spousal support; (5) failing to specify a termination date for the spousal support awarded; (6) awarding the ordered level of child support; (7) awarding Payne attorney's fees; and (8) failing to appropriately consider the evidence regarding the equitable distribution of the parties' property. Payne asserts on cross-appeal that the trial court erred in assessing against her a negative non-monetary contribution. In the alternative, Payne contends that the trial court improperly quantified the negative non-monetary contribution. For the reasons that follow, we affirm in part, and reverse in part.

I. Background
"Under familiar principles we view [the] evidence and all reasonable inferences in the light most favorable to the prevailing party below." Martin v. Pittsylvania County Dep't of Soc. Servs., 3 Va.App. 15, 20, 348 S.E.2d 13, 16 (1986).
The parties were married on August 9, 1980. There were two children of the parties' marriage: Elizabeth, born August 15, 1991, and Alexandra, born January 30, 1995. In January 1998, the parties agreed to separate. On July 2, 1998, Joynes filed his bill of complaint. The parties did not physically separate until November 27, 1998. From that time, until the resolution of the matter, the parties operated under an agreed upon pendente lite order.
An evidentiary hearing was held before the Commissioner in Chancery on May 3, 4, 5, 6, 7, and 10 of 1999. An additional hearing was held before the commissioner on May 29, 1999. The testimony presented during the hearing established that Payne had suffered from bulimia since her college years. Payne experienced periodic bouts of the disorder until approximately 1993, when a partner with the law firm where she worked informed Joynes of Payne's condition. Although Payne had denied any such disorder in the past, Payne admitted to her problem at that time. Since then, she has come to terms with the disorder and has sought treatment. At the time of the trial, Payne was "medically cured" of the bulimia but continued to consult with her physicians on a regular basis.
It was undisputed during the trial that the parties' children were physically healthy and enjoyed a good relationship with both parents. Payne had taken an extended leave of absence from her position as a partner in a law firm both before and after the birth of Elizabeth. In January, 1993, Payne reduced her employment to part-time, working only three days per week. She took a third extended leave of absence after the adoption of Alex, the parties' second child. Payne then *566 returned to work part-time until March, 1997, when she ceased work in order to attend to her family responsibilities. Joynes testified that he objected to Payne's decision to terminate her employment.
Until May, 1996, Joynes worked a considerable number of hours as a partner with another law firm. At that time, he was diagnosed with cancer and underwent surgery and treatment. Because of his illness, Joynes cut back his work hours but continued to work several hours every day.
Testimony established that Joynes enjoyed a good relationship with his family and had several family members living close by, who had a close relationship with the children. Payne's family resides in Florida, and, although her relationship with them was strained at one time, evidence was presented demonstrating that the relationship had improved. However, she and the children did not spend time with her family on a regular basis.
During the parties' separation, prior to the entry of the final decree, the evidence established that Payne allowed Joynes visitation as agreed upon in the decree. However, although Payne allowed Joynes additional visitation, she did not allow Joynes additional visitation on every occasion that Joynes requested it.
After the close of the evidence and upon review of written memoranda submitted by both parties, the commissioner filed his eighty-eight page report on January 4, 2000. The parties filed exceptions to the report and on March 27, 2000, argued their exceptions to the trial court. On April 10, 2000, Joynes filed a motion with the trial court, requesting a hearing to present new evidence. The trial court denied the motion on April 11, 2000 during a telephone conference among both parties' counsel and the court. After fully reviewing the extensive transcript, exhibits and legal memoranda, the trial court affirmed the commissioner's award on May 5, 2000. The final decree was entered on June 5, 2000.
On appeal, Joynes raises seventeen assignments of error. Payne, on cross-appeal, alleges three additional errors.[1]

II. Custody

We first note that:
[w]hile the report of a commissioner in chancery does not carry the weight of a jury's verdict, Code § 8.01-610, it should be sustained unless the trial court concludes that the commissioner's findings are not supported by the evidence. This rule applies with particular force to a commissioner's findings of fact based upon evidence taken in his presenee, but is not applicable to pure conclusions of law contained in the report. On appeal, a decree which approves a commissioner's report will be affirmed unless plainly wrong....
Hill v. Hill, 227 Va. 569, 576-77, 318 S.E.2d 292, 296 (1984).
With regard to the award of custody, Joynes argues that the commissioner and the trial court erred in: (1) failing to grant Joynes custody because the evidence established that Payne's actions had been adverse to the best interests of the children; (2) applying an erroneous burden of proof with respect to Joynes' petition for custody; (3) failing to substantively consider the factors set forth in Code § 20-124.3; (4) failing to consider Joynes as a custodial parent; (5) refusing Joynes' request to present additional evidence after the close of evidence; and (6) failing to establish the date of the award of custody as May 28, 1999, the date of the close of evidence.
In awarding Payne physical custody of the children, the commissioner found as follows with regard to Payne's bulimia:
in order to obtain physical custody solely as a result of defendant's bulimia, I think the plaintiff must show that the defendant is not consistently alert to any signs or symptoms of relapse and willing to seek immediate treatment, or that defendant does not fully understand the potential genetic *567 predisposition towards the illness and the role environmental factors may play in developing an eating disorder in children. The evidence does not prove the defendant lacking in either measure.

* * * * * *
For all of the above reasons, I find that defendant's bulimic condition, standing alone, is not a sufficient reason to award sole custody of Elizabeth and Alex to the plaintiff.
The commissioner then specifically discussed and considered each of the factors listed in Code § 20-124.3, as it read during the hearing of this matter.[2] The commissioner also recognized that serving the best interests of the children was his primary concern. He noted that Payne had been the primary nurturer and care-provider since the children's births. He also noted that Payne's "possessory stance" toward Joynes, with regard to visitation, could have a negative impact on the relationship between Joynes and the children. In addition, he stated that Joynes' "forays" with another woman caused him some concern. Yet, he found both Joynes and Payne to be fit parents and ultimately ruled that, "[i]n consideration of the evidence presented pursuant to Virginia Code §, 20-124.3, and the applicable case law, [he was] constrained to find that [Payne] should remain the physical custodian for Elizabeth and Alex."
"Code § 20-124.3 specifies the factors a court 'shall consider' in determining the best interests of a child for . . . custody or visitation. Although the trial court must examine all factors set out in Code § 20-124.3, it is not required to quantify or elaborate exactly what weight or consideration it has given to each of the statutory factors." Sargent v. Sargent, 20 Va.App. 694, 702, 460 S.E.2d 596, 599 (1995) (citations omitted). As long as evidence in the record supports the trial court's ruling and the trial court has not abused its discretion, its ruling must be affirmed on appeal. See Alphin v. Alphin, 15 Va.App. 395, 405, 424 S.E.2d 572, 578 (1992).
Here, the commissioner's extensive report demonstrates that he considered the statutory factors and made his decision based upon the children's best interests. Despite Joynes' assertion to the contrary, the record is replete with evidence in support of the commissioner's recommendation. See Sandoval v. Commonwealth, 20 Va.App. 133, 138, 455 S.E.2d 730, 732 (1995) ("The credibility of the witnesses and the weight accorded the evidence are matters solely for the fact finder who has the opportunity to see and hear that evidence as it is presented.").
Furthermore, the commissioner merely considered Joynes'"forays" with another woman, as well as Payne's past role as the primary nurturer and care-giver for the children. He did not rely solely on these factors in reaching his determination. In fact, he specifically stated that he did not *568 rely on Joynes' activities with another woman in reaching his decision. Thus, the commissioner's consideration of these factors is not error; rather, it merely demonstrates his resolve in carefully considering the voluminous amount of evidence presented and its relationship to the best interests of these children. See Brown v. Brown, 30 Va.App. 532, 538, 518 S.E.2d 336, 338 (1999) (the finder of fact is given broad discretion in determining what promotes the children's best interests).
Joynes additionally argues that the commissioner "imposed upon [him] an erroneous burden of proof with respect to his petition for custody" when he found that "Joynes could only be awarded custody if he could show that [Payne was] not constantly alert to any signs or symptoms of relapse and willing to seek immediate treatment, or that [Payne did] not fully understand that potential genetic predisposition towards the illness and the role environmental factors play in developing an eating disorder in children." However, Joynes misstates the commissioner's holding.
The commissioner held that "in order [for Joynes] to obtain physical custody solely as a result of defendant's bulimia," (emphasis added), the evidence must demonstrate the existence of a situation such as that described and set forth above. In so holding, the commissioner recognized that Joynes' custody case rested primarily on his argument that Payne was unfit to act as the physical custodian of the children due to her bulimic condition. The weight to be placed on this single factor, namely Payne's physical and mental condition, was within the discretion of the commissioner as fact finder. See Sargent, 20 Va.App. at 702, 460 S.E.2d at 600.
Joynes next argues that the trial court violated his due process rights by refusing to allow him to present additional evidence almost one year after the close of evidence in this matter. Simultaneously, Joynes argues that the trial court erred in failing to promptly adjudicate the matter. As a remedy, Joynes argues that the date of the award of custody should be May 28, 1999, the date of the close of evidence, instead of June 5, 2000, the date of the final decree.
Joynes is correct in noting that "[dlue process requires the courts to comply strictly with the statutory scheme for disposition of child custody cases." Rader v. Montgomery County, 5 Va.App. 523, 528, 365 S.E.2d 234, 237 (1988). Further, Code § 20-124.2 requires the trial court to "provide prompt adjudication upon due consideration of all the facts." However, introduction of additional evidence into the record after the commissioner has filed his report is treated as a motion to receive after-discovered evidence. See id.; see also Mundy v. Commonwealth, 11 Va.App. 461, 480, 390 S.E.2d 525, 535, aff'd en banc, 11 Va.App. 461, 399 S.E.2d 29 (1990), cert. denied, 502 U.S. 840, 112 S.Ct. 127, 116 L.Ed.2d 95 (1991). Four requirements must be met before a record can be reopened to receive additional evidence: (1) the evidence must have been discovered after the record was closed; (2) it could not have been obtained prior to the closing of the record through the exercise of reasonable diligence; (3) it is not merely cumulative, corroborative, or collateral; and (4) it is material, and as such, should produce an opposite result from that contained in the commissioner's report. Id.
Here, the record does not disclose the nature of the evidence, nor does it describe when and how the evidence was obtained. More importantly, the record does not disclose whether Joynes described to the trial court the nature of the evidence and the circumstances surrounding his request for an additional hearing. Accordingly, we cannot consider Joynes' argument in this regard on appeal. See Smith v. Hylton, 14 Va.App. 354, 357-58, 416 S.E.2d 712, 715 (1992) ("It is well settled that when a party's evidence has been ruled inadmissible, the party must proffer or avouch the evidence for the record in order to preserve the ruling for appeal; otherwise, the appellate court has no basis to decide whether the evidence was admissible."). Thus, we need not consider the "appropriate remedy," as Joynes suggests.
Finally, we find that the trial court's ruling of May 5, 2000 and final decree of June 5, 2000 were sufficiently "prompt" in light of *569 the voluminous pleadings and evidence this matter.[3]

III. Spousal Support

Joynes next argues that the trial court erred by using an "erroneous standard" in imputing income to Payne in its determination of spousal support. Joynes also argues that the trial court awarded Payne spousal support in excess of need and failed to give substantive consideration to the statutory factors set forth in Code § 20-107.1(E). Finally, Joynes contends that the trial court erred in failing to specify a termination date for the spousal support award, as required by Code § 20-107.1(C).
"In awarding spousal support, the chancellor must consider the relative needs and abilities of the parties. He is guided by the . . . factors that are set forth in Code § 20-107.1. When the chancellor has given due consideration to these factors, his determination will not be disturbed on appeal except for a clear abuse of discretion."[4]Collier vja8Collier, 2 Va.App. 125, 129, 341 S.E.2d 827, 829 (1986). "The trial court is not required to quantify or elaborate exactly what weight or consideration it has given to each of the statutory factors." Woolley v. Woolley, 3 Va.App. 337, 345, 349 S.E.2d 422, 426 (1986). However, its findings "must have some foundation based on the evidence presented." Id.
The evidence demonstrated that at the time Payne left her part-time employment in March, 1997, she was making approximately $80,000 per year. Payne had made $94,430 in 1992, when she was still working on a full-time basis. At the time of the trial and for a number of years preceding the trial, Joynes earned approximately $300,000 per year. Joynes presented testimony establishing that Payne could earn approximately $170,386 per year, were she to return to full-time employment with the law firm she had previously worked for.
In making his determination concerning spousal support, the commissioner *570 specifically considered each of the statutory factors set forth in Code § 20-107.1(E). Further, the commissioner, quoting Srinivasan v. Srinivasan, 10 Va App. 728, 734, 396 S.E.2d 675, 679 (1990), recognized that a party who "`seeks spousal support is required to earn as much as he or she reasonably can to decrease the amount of support needed.'" He found that Payne had "offered no factual basis which would preclude her from working" and "no legal basis why income should not be imputed to her." However, in determining "what amount could be anticipated had [Payne] continued in her employment," as required by Brody v. Brody, 16 Va.App. 647, 432 S.E.2d 20 (1993), the commissioner did not accept the testimony of Joynes' witness concerning Payne's salary potential with her previous employer. The commissioner found that Payne had, at no point in her career, made even close to the amount projected.
"[W]e have held that the court, in setting support awards, must look to current circumstances and what the circumstances will be 'within the immediate or reasonably foreseeable future,' not to what may happen in the future." Srinivasan, 10 Va.App. at 735, 396 S.E.2d at 679 (emphasis added). Thus, the commissioner did not abuse his discretion in refusing to accept the testimony of the expert witness and, instead, basing his determination on the past earning capacity demonstrated by Payne.
"In awarding spousal support, the chancellor must consider the relative needs and abilities of the parties. He is guided by the nine factors that are set forth in Code § 20-107.1." Collier, 2 Va.App. at 129, 341 S.E.2d at 829. "In fixing the amount of support, the trial 'court must look to the financial needs of the [receiving party], her age, physical condition and ability to earn, and balance against these circumstances the financial ability of the [other spouse] to pay, considering his income and his ability to earn.'" Alphin, 15 Va.App. at 401, 424 S.E.2d at 575. As stated above, the commissioner very carefully considered the statutory factors. Furthermore, although Joynes objected to Payne's decision to end her employment altogether, he had supported her election to work part-time and had accepted her contributions to the household in this regard. In weighing the relative needs, earning capacities and abilities of the parties, their ages, the duration of the marriage, and the manner in which the parties were accustomed to living during the marriage, the commissioner did not abuse his discretion in determining the spousal support award.
Each party also disputes several amounts utilized by the commissioner in determining each party's monthly expenses/income. Joynes asserts that, in determining Payne's adjusted monthly need of $1,051, the commissioner failed to consider the $800 per month rental income received by Payne from a condominium she retained, as well as interest income Payne would receive from assets she retained as a result of the equitable distribution award. Contrary to Joynes' assertion otherwise, the record demonstrates that the commissioner expressly considered the rental income from the parties' condominium, as well as the potential interest income resulting from the division of marital property.
Payne argues that the commissioner arbitrarily reduced several of the monthly expenses that she had claimed in determining her adjusted need and that the commissioner failed to consider her necessary expense of $309.60 per month for real estate expenses. We find no abuse of discretion in the commissioner's reduction of several of Payne's alleged expenses. Further, the record established that the commissioner indeed considered the evidence that Payne presented with regard to the $309.60 real estate tax expense.
As stated above, the commissioner clearly considered the necessary factors and based his determination not on a specific dollar amount, but upon the evidence presented and the relative needs of the parties and their ability to pay. We find no authority requiring the commissioner to determine a spousal support award based upon an exact monetary figure, nor has Joynes or Payne presented any such authority. To the contrary, we have held that "in fixing spousal support, a trial court has broad discretion which should not be interfered with by an appellate court unless it is clear that some *571 injustice has been done." Papuchis v. Papuchis, 2 Va.App. 130, 133, 341 S.E.2d 829, 831 (1986). Thus, we find that the evidence sufficiently supports the commissioner's determination and, therefore, find no abuse of discretion.
Finally, Code § 20-107.1 provides that "[t]he court, in its discretion, may decree that maintenance and support of a spouse be made in periodic payments for a defined duration, or in periodic payments for an undefined duration, or in a lump sum award, or in any combination thereof." Contrary to Joynes' argument, this statute does not require the trial court to specify the date of termination of a spousal support award. In fact, the language allows the trial court to order an award for an undefined duration. Thus, we find no abuse of discretion in the trial court's failure to specify a date of termination for the award.

IV. Child Support

Joynes next contends that the trial court erred in directing an upward deviation from the support dictated by the guidelines, for the payment of Elizabeth's private school tuition. Joynes also contends that the trial court "failed to issue a ruling with respect to [Payne's] child support obligation."
"Decisions concerning child support rest within the sound discretion of the trial court and will not be reversed on appeal unless plainly wrong or unsupported by the evidence." Smith v. Smith, 18 Va.App. 427, 433, 444 S.E.2d 269, 274 (1994). Joynes contends that the trial court lacked statutory authority to order payments of child support for educational expenses. However, Code § 20-108.1(B) clearly states that the presumptive child support amount may be rebutted. Such a finding shall be determined by considering several factors "affecting the obligation, the ability of each party to provide child support, and the best interests of the child." Code § 20-108.1(B). One of these factors is "[d]irect payments ordered by the court for .. education expenses, or other court-ordered direct payments for the benefit of the child . ." Code § 20-108.1(B)(6).
We have applied this language in finding that "a parent may be required to pay for private educational expenses, even though such expenses exceed the guidelines, when there is a demonstrated need for the child to attend private school and the parent has the ability to pay." Ragsdale v. Ragsdale, 30 Va.App. 283, 295, 516 S.E.2d 698, 704 (1999) (citing Solomond v. Ball, 22 Va.App. 385, 391, 470 S.E.2d 157, 160 (1996)). In making this determination, the trial court must consider "factors such as the availability of satisfactory public schools, the child's attendance at private school prior to the separation and divorce, the child's special emotional or physical needs, religious training, and family tradition." Solomond, 22 Va. App. at 391, 470 S.E.2d at 160.
In this case, it is clear that the commissioner considered each of these factors in reaching his determination. Joynes' argument that the commissioner should have given greater weight to factors one and three is simply not supported by law. Instead, the commissioner was merely required to consider these factors in determining whether there was a need for Elizabeth to attend a private school, and whether the parents possessed the ability to pay. We find that there was sufficient evidence to support the commissioner's determination and, therefore, that there was no abuse of discretion.
Joynes next argues that the trial court failed to address Payne's child support obligation. Joynes correctly states that "[b]oth parents owe a duty of support to their minor children" and that the obligation is calculated by considering the "combined monthly gross income" of both parents. Bennett v. Commonwealth, 22 Va.App. 684, 691, 472 S.E.2d 668, 672 (1996); Code § 20-108.2. Here, the commissioner clearly considered both the imputed gross income to Payne of approximately $80,000 per year and Joynes' annual gross income in determining the amount of support each parent would provide. However, "under prior binding case law, it is clear that parents 'cannot contract away their children's rights to support nor can a court be precluded by agreement from exercising its power to decree child support.'" Kelley v. Kelley, 248 Va. 295, 298, *572 449 S.E.2d 55, 56 (1994). Thus, the parties' agreement during the marriage that Payne would remain employed on a part-time basis cannot substitute for the fact finder's analysis of the factors that must be considered when determining child support and the parties' respective obligations for its payment. We find that the commissioner's decision to impute income to Payne in an amount equal to her part-time employment was plainly wrong, and we remand the matter on this issue.

V. Equitable Distribution

Joynes next argues that the trial court's equitable distribution award was erroneous to the extent it classified contributions made to Joynes' 401(k) plan after March, 1998, classified his January, 1998 bonus as marital property, classified certain property as Payne's separate property, classified Joynes' split-dollar life insurance policy as marital property, and divided the marital assets on a 53%/47% basis.[5]
"Fashioning an equitable distribution award lies within the sound discretion of the trial judge and that award will not be set aside unless it is plainly wrong or without evidence to support it." Srinivasan, 10 Va.App. at 732, 396 S.E.2d at 678. Here, after hearing the evidence, the commissioner ruled that the parties' final separation occurred on November 28, 1998, when the parties physically separated. We find the evidence sufficient to support this finding and find that it is not "plainly wrong." Accordingly, the commissioner correctly determined that all payroll deductions earned and/or paid before November 28, 1998 were marital property pursuant to Code § 20-107.3.
Furthermore, we find no error in the commissioner's classification of the entire lump-sum contribution made to the 401(k) plan in 1998 as marital property. No evidence was presented to the commissioner establishing the amount or percentage of the contribution that could be attributable to the post-separation period of the parties. Therefore, his recommendation in this regard was not plainly wrong.
Next, we find no error in the commissioner's determination that a portion of the bonus received by Joynes in 1998 was marital property. As the commissioner noted, although Joynes was required to be employed by his employer at the end of 1998, one month after the parties' separation, in order to receive the bonus, the bonus represented compensation for Joynes' labor during the entire year of 1998, and, thus, was property acquired prior to the separation. See Luczkovich v. Luczkovich, 26 Va.App. 702, 496 S.E.2d 157 (1998) (holding that severance pay received post-separation was not marital property as the condition to receive the pay was related to the sale of the corporation, not to husband's work during his marriage).
We also find no error in the commissioner's determination of certain property as Payne's separate property. The commissioner apparently relied upon discovery responses propounded by Payne, designating certain property as separate property, as *573 well as discovery responses propounded by Joynes denying that the property was separate property. "All property acquired by either spouse during the marriage is presumed to be marital property in the absence of satisfactory evidence that it is separate property.... The party claiming that property should be classified as separate has the burden to produce satisfactory evidence to rebut this presumption." Stroop v. Stroop, 10 Va.App. 611, 614-15, 394 S.E.2d 861, 863 (1990). The valuation by the trial court cannot be based on mere guesswork. However, the burden is on the parties to provide the trial court sufficient evidence from which it can value their property. See Stratton v. Stratton, 16 Va.App. 878, 883, 433 S.E.2d 920, 922 (1993) (citation omitted).
On appeal, Joynes has not pointed with specificity to any item for which the commissioner was demonstrably in error in its classification. Therefore, as the commissioner had at least some evidence, which he found credible, upon which to base his decision concerning the parties' personal property, we cannot say on the record before us that he abused his discretion in awarding Payne the designated items.
We further find that the commis sioner did not err in classifying a portion of Joynes' split-dollar life insurance policy as marital property, despite the fact that Joynes could only receive it based upon the occurrence of a future event. A witness from Joynes' employer testified that the plan was a "deferred compensation" plan. Such benefits are classified as marital property pursuant to Code § 20-107.3(G).
Finally, we see no error in the commissioner's distribution of the assets based upon his consideration of the factors set forth in Code § 20-107.3(E). The commissioner clearly considered each of the factors required, in determining that Joynes' higher level of compensation entitled him to more than one-half of the assets, while Payne's monetary contributions, as well as non-monetary contributions, also entitled her to a substantial proportion of the assets. The record was replete with evidence supporting this determination. Accordingly, we cannot say that the commissioner abused his discretion in fashioning the award in this manner.

VI. Attorney Fees

Joynes finally argues that the trial court inappropriately awarded Payne 45% of her attorney fees as well as certain costs, as recommended by the commissioner. We find no merit in Joynes' argument that Payne was not a prevailing party and, therefore, not entitled to fees.
An award of attorney's fees is a matter submitted to the sound discretion of the trial court and is reviewable on appeal only for an abuse of discretion. See Graves v. Graves, 4 Va.App. 326, 333, 357 S.E.2d 554, 558 (1987). The key to a proper award of counsel fees is reasonableness under all the circumstances. See McGinnis v. McGinnis, 1 Va.App. 272, 277, 338 S.E.2d 159, 162 (1985).
Here, the commissioner very carefully considered the claims involved in the divorce proceedings, as well as the complexity of the matter, the outcome of the entire proceedings, and the nature of the expenses, in determining his award. We find no abuse of discretion in the commissioner's recommendation, or the trial court's award under the circumstances of this case.

VII. Negative Imputation of Income

Finally, Payne asserts on cross-appeal that the commissioner erred in imputing a negative non-monetary contribution to her based on her termination of employment. In the alternative, Payne argues that the commissioner incorrectly quantified the negative non-monetary contribution.
As stated above, "decisions concerning equitable distribution rest within the sound discretion of the trial court and will not be reversed on appeal unless plainly wrong or unsupported by the evidence." McDavid v. McDavid, 19 Va.App. 406, 407-08, 451 S.E.2d 713, 715 (1994), We have held that
"[c]ircumstances that lead to the dissolution of the marriage but have no effect upon marital property, its value, or otherwise are not relevant in determining a *574 monetary award, need not be considered. A trial court may only consider those circumstances leading to the dissolution of the marriage, that are relevant to determining a monetary award in order to avoid an unreasonable result."
O'Loughlin v. O'Loughlin, 20 Va.App. 522, 527, 458 S.E.2d 323, 326 (1995) (citation omitted). Here, the commissioner apparently viewed Payne's conduct in terminating her employment as a factor leading to the dissolution of the marriage and considered its effect on the marital property. Indeed, Joynes testified that he was against Payne's termination of employment. Thus, we cannot hold that the trial court abused its discretion in determining that Payne's action in this regard constituted a negative non-monetary contribution to the marriage. Furthermore, we find no authority requiring the trial court to value the negative non-monetary contribution on a dollar-for-dollar basis. Accordingly, we find no error in the commissioner's failure to consider the child care expenses the parties would have paid had Payne continued to work in determining the effect of Payne's negative non-monetary contribution.
We do not consider Payne's additional argument regarding the quantification of the negative non-monetary contribution because she raised no exception in this regard before the commissioner and trial court and, therefore, failed to properly preserve this issue for appeal. See Rule 5A:18.
In summary, we affirm the judgment of the trial court on each of the issues raised by the parties, with the exception of the trial court's ruling as it pertained to Payne's child support obligation. On that issue alone, this matter is reversed and remanded for further proceedings consistent with this opinion.
Affirmed in part, and reversed and remanded in part.
NOTES
[1]  Following oral argument, Joynes filed a "Motion to Strike" from the record comments made by counsel for Payne in his argument before us. This motion was opposed by Payne. We are cognizant of the facts contained in the record and we note that counsel for Joynes had the opportunity for rebuttal argument. Accordingly, we decline to grant Joynes' motion.
[2]  Code § 20-124.3 states as follows:

In determining best interests of a child for purposes of determining custody or visitation arrangements including any pendente lite orders pursuant to § 20-.103, the court shall consider the following:
1. The age and physical and mental condition of the child, giving due consideration to the child's changing developmental needs;
2. The age and physical and mental condition of each parent;
3. The relationship existing between each parent and each child, giving due consideration to the positive involvement with the child's life, the ability to accurately assess and meet the emotional, intellectual and physical needs of the child;
4. The needs of the child, giving due consideration to other important relationships of the child, including but not limited to siblings, peers and extended family members;
5. The role which each parent has played and will play in the future, in the upbringing and care of the child;
6. The propensity of each parent to actively support the child's contact and relationship with the other parent, the relative willingness and demonstrated ability of each parent to maintain a close and continuing relationship with the child, and the ability of each parent to cooperate in matters affecting the child;
7. The reasonable preference of the child, if the court deems the child to be of reasonable intelligence, understanding, age and experience to express such a preference;
8. Any history of family abuse as that term is defined in § 16.1-228; and
9. Such other factors as the court deems necessary and proper to the determination.
[3]  As stated previously, the hearing before the commissioner spanned over seven days. Subsequently, both parties were given time before the trial court to argue their exceptions to the commissioner's report, and the trial court held yet another hearing, by telephone conference, to hear argument and make a ruling concerning Joynes' request to submit additional evidence. Moreover, the joint appendix on appeal, which does not contain the full record, includes over 4,000 pages of pleadings, exhibits and transcripts, reflecting the complexity of the initial proceedings in this matter.
[4]  Code § 20-107.1(E) provides the following:
