OPINION
¶ 1 We examine whether stock options that had not vested before the petition for dissolution was served can be divided as community property. Because we find that the trial court needs to determine whether the un-vested stock options were compensation for past performance, incentives for future performance or some combination of both, we reverse that portion of the decree of dissolution and remand the matter to the trial court. 1
FACTUAL AND PROCEDURAL BACKGROUND
¶ 2 William J. Brebaugh (“Husband”) and Nancy L. Deane (“Wife”) were divorced after thirty years of marriage. Husband is the vice president of enrollment at Apollo Group, Inc./University of Phoenix (“Apollo”). Wife teaches art in the Scottsdale School District. The parties were unable to resolve whether Husband’s unvested stock options were community property. After their trial, the court determined the unvested stock options were community property and awarded Wife one-half of those options. Husband appealed and we have jurisdiction pursuant to Arizona Revised Statutes (“A.R.S.”) section 12-2101(B) (2003).
DISCUSSION
¶ 3 Husband received blocks of stock options from his employer during the marriage. The parties agreed that stock options that had vested prior to the date the petition was served were community property. They also agreed that stock options he received after service were his separate property. They could not agree, however, whether the options he received during the marriage but could not be exercised until after service of the petition were community or separate property.
¶4 The trial court, after consideration of testimony, memoranda and proposed findings of fact and conclusions of law, noted that the issue was how any community interest in the unvested options should be determined. After noting that Arizona has not examined the issue, the trial court examined the “time rule” outlined in
In re Marriage of Hug,
¶ 5 On appeal, Husband contends that we should allocate the community and separate property interests in unvested stock options using a formula that favors the future efforts of the employee-spouse.
See generally In re Marriage of Nelson,
¶ 6 Stock options are a form of compensation.
See In re Marriage of Robinson and Thiel,
¶ 7 In Arizona, the community has an interest in the property earned during the marriage.
See Van Loan v. Van Loan,
¶ 8 Arizona courts have held that “pension rights, whether vested or non-vested, are community property insofar as the rights were acquired during marriage.”
Johnson v. Johnson,
¶ 9 Most jurisdictions have applied a time rule for determining the community’s interest in unvested stock options.
See, e.g., Baccanti v. Morton,
¶ 10 As the trial court recognized, the purpose of stock options varies widely. A company may award stock options as compensation for past services or performance, as incentive to remain with the company, or to garner favorable tax consequences. Therefore, we agree that “[tjrial courts should be vested with broad discretion to fashion approaches which will achieve the most equitable results under the facts of each case.”
Hug,
¶ 11 Here, the trial court concluded that Husband’s stock options compensated him for work performed during the marriage and rejected his claim that the options were solely intended to encourage him to remain with Apollo. It concluded, based on the date the options were granted, that all options granted during the marriage, whether vested or not at the time of service, were community property. The stock option agreements do not, however, appear to support that conclusion.
¶ 12 The stock option agreements provide that the options were intended to encourage key employees to remain and to enhance Apollo’s ability to attract new employees “by providing an opportunity to have a proprietary interest in the success of [Apollo,]” and as an incentive to “focus on [its] long-term growth.” The agreements provided that the options could vest on an accelerated basis if Apollo reached certain profit goals and the stock price reached a designated amount. Alternatively, and regardless of Apollo’s performance, twenty-five percent of the options would vest annually beginning the year after the options were awarded.
¶ 13 Apollo’s chief financial officer, Kenda Gonzalez, moreover, testified that stock op *99 tions generally are granted as an incentive for employees to remain with a company, to think like stockholders and thereby consider the company’s long-term benefits. She also testified that Apollo grants options based on the employee’s level of responsibility within the company, not for past performance. Husband’s expert accountant testified that Apollo’s stock options were an inducement to keep him with the company and not to reward him for past performance.
¶ 14 Wife’s expert accountant testified that Husband’s stock options were compensation for past efforts. She opined that because Apollo’s enrollment had increased significantly during Husband’s tenure as vice president of enrollment, which increased the gross income for the corporation, his salary and bonuses alone were inadequate compensation. Husband admitted that he would not stay with the company if he only received his salary and bonuses. Husband received regular merit raises and bonuses during his employment, but did not receive stock options on a regular basis.
¶ 15 If the stock options were intended solely as compensation for work performed or deferred compensation, the trial court’s characterization would be correct. It does not appear, however, that the court considered the fact that the agreements specifically stated that the options were intended to encourage key employees to remain with Apollo and enhance Apollo’s ability to attract new employees. The language of the agreements sufficiently rebuts the presumption that the options granted during the marriage are entirely community property.
See Thomas,
¶ 16 We have found only two jurisdictions that have held that unvested stock options were entirely community property. In
Bo-din v. Bodin,
a Texas appellate court affirmed the trial court’s ruling that unvested stock options, like military retirement benefits, were a community asset because they constituted a contingent interest in property earned during the marriage.
¶ 17 The other Texas cases that treated unvested stock options as entirely community property are distinguishable. In
Kline v. Kline,
the court found that because the stock option agreement indicated that the unvested options were for past performance they were entirely community property.
¶ 18 In Wisconsin, the court of appeals presumed that unvested stock options were community property.
See Chen v. Chen,
¶ 19 Here, if the trial court concludes, after reviewing the agreements, that the unvested stock options were, even in part, incentives for future performance, it should
*100
analyze the issue under
Hug
and
Nelson,
and use a time rule to determine the community and separate property interests in the un-vested stock options. Our conclusion is supported by the fact that a similar fractional formula is used to determine the community’s interest in unvested pension or retirement plans.
See Johnson,
¶ 20 A majority of courts that have examined whether unvested stock options that vest after separation or service of the petition have accepted two primary time-rule formulas for allocating unvested stock options. The first is the
Hug
formula which is most appropriate for stock options that are granted for past services but cannot be exercised until after the separation or service of process because the formula gives more weight to the employee’s entire tenure with the employer during marriage.
See Garcia,
the number of options determined to be community [is] the product of a fraction in which the numerator [is] the period in months from the commencement of the spouse’s tenure with his employer to the date of the couple’s separation, and the denominator [is] the period in months between commencement of employment and the date when each group of options first bec[o]me[s] exercisable. This fraction [is] then multiplied by the number of shares of stock which e[an] be purchased with each block of options, yielding the community figure.
Nelson,
¶21 Conversely, the Nelson formula is more appropriate for stock options which are intended to compensate an employee for future efforts. The Nelson formula assumes that the period of employment prior to the granting of the option did not contribute to the employee earning the stock options and should not be included in the time used to calculate the community’s interest in the options. See id. at 793 n. 3. In Nelson, the numerator of the fraction is “the number of months from the date of grant of each block of options to the date of the couple’s separation, while the denominator [is] the period from the time of each grant to its date of exercisability.” Id. at 793. This fraction is also multiplied by the number of shares to be purchased to determine the community figure. Id.
¶ 22 Other courts have used other methods of valuation.
See, e.g., Batra v. Batra,
¶ 23 “The valuation of assets is a factual determination that must be based on the facts and circumstances of each ease.”
Kelsey v. Kelsey,
¶ 24 Although Husband contends that his options were incentive for future perform- *101 anee and Wife contends they were for past performance, we will leave it to the trial court to determine whether the disputed options were incentives for the future, compensation for past performance, or some combination of both. Once it makes that determination, it can decide which time-rule formula is most appropriate.
¶25 The primary factor the trial court should consider is the employer’s intent in awarding the options.
See e.g., Ruberg v. Ruberg,
¶ 26 Accordingly, we reverse the portion of the decree dividing the unvested stock options and remand for further findings consistent with this opinion.
¶ 27 Both parties request their attorneys’ fees and costs on appeal pursuant to A.R.S. § 25-324 (2000) and Arizona Rule of Civil Appellate Procedure 21. Neither party has taken an unreasonable position on appeal, and both parties have significant financial resources, considering all sources. Consequently, we deny both requests for fees and costs on appeal.
CONCLUSION
¶28 We reverse the conclusion that all unvested stock options granted during marriage but vesting after the dissolution petition was served are community property, and the division of those options. We remand so that the trial court can consider the reasons Husband received the unvested options and the most appropriate time-rule formula, if any, to divide them. Each party shall bear his or her own attorneys’ fees and costs on appeal.
Notes
. In our separate Memorandum Decision, filed herewith, we affirmed that Wife is entitled to indefinite spousal maintenance, but remanded to the trial court to resolve the amount of monthly maintenance once it resolves the issue in this Opinion. We also affirmed that the vehicle Husband gave her was a gift in spite of an agreement to the contrary; and pursuant to Wife’s concession, vacated the portion of the dissolution decree that awarded her a share of the condominium rentals.
. We were unable to locate another case following this rationale.
