¶ 1. Van Steiner appeals a divorce judgment of the circuit court. Van challenges the property division and maintenance provisions of that judgment. He argues that the court erred when it treated his sick leave account as a consideration under Wis. Stat. § 767.255(3) (2001-02)1 when awarding Lynn Steiner more than half of the divisible property. Van also argues that the court erred when it denied his request for maintenance. We disagree with Van and affirm the circuit court.
Background
¶ 2. Van and Lynn were married on April 11, 1964. They were divorced on January 6, 2003, when Van was sixty-one years old and retired and Lynn was fifty-nine years old and working thirty hours per week as a nurse.
¶ 3. After a contested divorce hearing, the circuit court determined that an unequal distribution of Lynn and Van's divisible property was warranted. The court awarded Lynn property valued at approximately $107,198, and Van property valued at approximately *293$30,909.2 The court deviated from the statutory presumption of equal property division after considering Van's non-divisible property, including a sick leave account valued at approximately $89,000. In its decision, the court noted that although Van's sick leave account was not property subject to division, it could be considered under Wis. Stat. § 767.255(3) as background information.
¶ 4. The circuit court also denied Van’s request that Lynn pay him maintenance and Van's alternative request that maintenance be held open. The court denied these requests based partly on evidence that Van could support himself with income from social security, his Wisconsin retirement, and his inheritance and by earning about $15,000 per year working part time.
Discussion
Sick Leave Account
¶ 5. Van contends that the circuit court erred when it relied on the value of his sick leave account to deviate from an equal property division. He contends that consideration of his sick leave account runs afoul of our decision in Preiss v. Preiss, 2000 WI App 185, 238 Wis. 2d 368, 617 N.W.2d 514. We disagree, and begin our discussion by summarizing Preiss. 3
*294¶ 6. In Preiss, we reviewed a decision to place a value on a party's sick leave account and treat the account as divisible property. It is undisputed that Van's sick leave account is the same type of government sick leave account that was at issue in Preiss. In both, accumulated sick leave account hours are valued at the employee's hourly rate of pay at the time of retirement and then converted to credits that may only be used to pay the employee's health insurance premiums. Id., ¶ 13. The account cannot be given away or transferred. Id., ¶ 14.
¶ 7. We concluded in Preiss that the circuit court erroneously treated the sick leave account as divisible property. We explained:
*295[The husband] cannot convey his interest in the account; he cannot gift it; he cannot transfer it. Because the account has no cash value and cannot be sold or transferred, it also does not have a fair market value. "Property to be divided at divorce is to be valued at its fair market value. Fair market value assumes sale by one who desires but is not obligated to sell and purchase by one willing but not obligated to buy." A transaction that would determine the property's fair market value cannot be made. If property has no fair market value, the court cannot place an independent value upon it, and it should thus not be included as an asset in the marital estate.
The account does indeed have an intrinsic value. It has value to [the husband], but this value is not accessible to anyone else.
Id., ¶¶ 14-15 (citation omitted).
¶ 8. Van asserts that if a sick leave account may not be directly treated as divisible property, it may not be considered for purposes of property division. He reasons that because Preiss prohibits sick leave accounts from coming in the front door as divisible property, the circuit court should not be permitted to bring his account in the back door as a "consideration" and achieve the same result. Lynn responds that Preiss only prohibits treating sick leave accounts as divisible property and that, under Wis. Stat. § 767.255(3)(j), a sick leave account is exactly the type of asset courts are permitted to consider as background information when deciding whether to deviate from an equal property division. We think Lynn has the better argument.4
*296¶ 9. "The division of a marital estate is governed by Wis. Stat. § 767.255, which creates a presumption that the property will be divided equally." Preiss, 238 Wis. 2d 368, ¶ 10. Wisconsin Stat. § 767.255(3) provides, in relevant part:
The court shall presume that all property not described in sub. (2) (a) is to be divided equally between the parties, but may alter this distribution without regard to marital misconduct after considering all of the following:
(j) Other economic circumstances of each party, including pension benefits, vested or unvested, and future interests.
We agree with Lynn that Van's sick leave account is an "other economic circumstance" akin to unvested pension benefits. Neither is owned and, thus, neither can be transferred or sold. Still, both have readily apparent value, even though that value is contingent on future events. In Preiss, we acknowledged that sick leave accounts have value: "The account does indeed have *297an intrinsic value. It has value to [the husband], but this value is not accessible to anyone else." Preiss, 238 Wis. 2d 368, ¶ 15.
¶ 10. Contrary to Van's argument, we did not hold in Preiss that a sick leave account has no identifiable value. We more specifically held that it does not have a "fair market" value as that term was explained in Sommerfield v. Sommerfield, 154 Wis. 2d 840, 853, 454 N.W.2d 55 (Ct. App. 1990). Preiss, 238 Wis. 2d 368, ¶ 14. To repeat, we acknowledged in Preiss that a sick leave account does have value. Id., ¶ 15. In fact, when we went on to suggest that the value of a sick leave account may be considered if the topic is maintenance or child support, we implicitly said that such accounts have an identifiable value. We stated: "If maintenance or child support were at issue, then the fact that [one party] receives his health insurance premiums through the sick leave account would likely be considered in determining his living expenses and his ability to pay maintenance or child support." Id., ¶ 16. If an asset can be valued with sufficient accuracy for purposes of determining appropriate maintenance and child support, we discern no reason why it cannot be a consideration under Wis. Stat. § 767.255(3)(j) for property division purposes.
¶ 11. We pause here to briefly compare Preiss with Chen v. Chen, 142 Wis. 2d 7, 416 N.W.2d 661 (Ct. App. 1987), and to point out that Chen supports our decision. In Preiss, we held that sick leave accounts are non-divisible property because they cannot be sold or transferred and, therefore, have no "fair market value." Preiss, 238 Wis. 2d 368, ¶ 14. In Chen, we concluded that unvested stock options — options that are "unas-signable and unsalable" with no currently determinable value — may be treated as divisible property. Chen, 142 *298Wis. 2d at 10-12. We stated in Chen: "The mere fact that the interest in the asset is contingent does not mean that it may be ignored." Id. at 12. Thus, the types of assets at issue in both Preiss and Chen appear to share similar characteristics when viewed at the time of the property division decision. Still, these two types of assets do have different characteristics and it may be possible to reconcile Preiss and Chen. That specific question is not before us.
¶ 12. We mention Chen here because its reasoning affirmatively supports using an asset like a sick leave account as a consideration under Wis. Stat. § 767.255(3). Both sick leave accounts and unvested stock options have uncertain value because their value is contingent on future events. If unvested stock options may be treated as divisible property, courts should be permitted, at a minimum, to use sick leave accounts as a background consideration for purposes of determining an equitable property division.
¶ 13. We affirm the circuit court's consideration of Van's sick leave account and, therefore, also affirm the circuit court's property division award.5
Maintenance
¶ 14. The circuit court declined to order maintenance or to hold open the topic, explaining that its decision was "[b]ased upon projections [that] future income of the parties will be relatively equal varying with their hours of employment." In essence, the court *299found that both Van and Lynn were employable and each could attain approximately the same total income if they both chose to continue working. The court provided the following reasons for denying Van maintenance:
(a) [Van] is 61 years of age, has an associate degree in electronics, and worked in various capacities for the University in radio electronics, for the most part with public radio. He is now retired and self-employed in his area of specialty.
(b) The court finds the evidence insufficient to make a determination in support of [Van's] claim to be disabled from a motorcycle accident. There was no expert medical testimony or documents to substantiate such claim.
(c) Two vocational specialists testified for the respective parties and both opined that at a minimum [Van] could work part time.
(d) The records support [Van] earning between $20 and $40 per hour when working in his area.
(e) In addition, [Van] is eligible for Social Security on his next birthday, has his Wisconsin Retirement (one-half thereof), and has his inheritance which, if properly managed, will produce additional income.
(f) The court also took into consideration that when [Van] draws Social Security, the amount of income he can earn monthly without affecting his benefit is limited to $970 per month until the age of 65.
(g) The court finds [Van] able to support himself.
¶ 15. Van challenges the denial of maintenance. He begins his argument by reciting some of the trial evidence regarding his ability to find employment. Van *300acknowledges that one expert testified that Van could earn $10,000 to $15,000 per year, and that another expert believed Van could find "part-time" work at $20 to $22 per hour. Van then asserts that it is difficult to know how the circuit court arrived at the conclusion that the future incomes of Van and Lynn would be relatively equal. Van complains that the court did not make a finding as to when Van would find a job or for how long he would be employed.
¶ 16. We are not sure just what Van is arguing. If he is arguing that the record does not support factual findings that he is able to earn about $15,000 per year working part time and that he is able to do so for approximately the same length of time Lynn is able to work, he is wrong.6 Van retired in March of 2002, at age sixty. The divorce trial was held in January of 2003. At that time, Van was sixty-one and Lynn was fifty-nine. Lynn, a nurse, had a gross monthly income of $3,075, working thirty hours per week. Van had worked in a temporary part-time position as recently as two months prior to trial at a rate of $40 per hour. That part-time job lasted about six months. A reasonable inference from the evidence is that Van voluntarily left that job when he decided not to pursue continued employment when the employer reduced the hourly rate to $19. Expert witness Kevin Schütz testified that Van could "most probably" secure part-time work, and also "probably" full-time work, at $20 to $22 per hour. Schütz pointed to a specific job opening to support that opin*301ion. Lynn testified that Van had always been able to find consulting work in the past. Lynn testified that, at Van's retirement party, she was told Van could return to work at the University as a limited-term employee. This summary of trial evidence shows that the record easily supports a factual finding that Van could find work that would produce approximately $15,000 a year in income. Since Van and Lynn are just two years apart in age, it is reasonable to infer that they both could work for approximately the same number of years into the future.
¶ 17. If Van is arguing that his income will not be "relatively equal" to Lynn's even if he makes about $15,000 per year, he does not develop that argument. At any rate, this argument is amply rebutted in Lynn's responsive brief. Lynn explains that an accountant testified and gave detailed testimony factoring in other income sources and what might happen at various points in time in the near future when Van and Lynn become eligible for other benefits such as social security. Taking these other factors into account, Lynn shows how the testimony supports a finding that Van's income will be relatively equal to Lynn's so long as Van pursues part-time work. Van does not respond in his reply brief to Lynn's analysis, and we deem this omission a concession. See Schlieper v. DNR, 188 Wis. 2d 318, 322, 525 N.W.2d 99 (Ct. App. 1994) (arguments not refuted may be deemed conceded).
¶ 18. Finally, if Van is simply arguing that the circuit court failed to adequately explain its decision, Van's argument is incomplete. Nowhere in his brief does he attempt to demonstrate that the full record fails to support the court's maintenance decision. It is not enough for a challenging party to assert or even to *302demonstrate that a circuit court has failed to adequately explain a maintenance decision. "When the circuit court does not explain its reason for a discretionary decision, we may search the record to determine whether it supports [the] circuit court's decision." Finley v. Finley, 2002 WI App 144, ¶ 19, 256 Wis. 2d 508, 648 N.W.2d 536. Because Van has not attempted to show that the record does not support the circuit court's decision, we need address this topic no further.
¶ 19. Accordingly, we conclude that Van has provided no reason to reverse the circuit court with respect to maintenance.
By the Court. — Judgment affirmed.
