Steve Chen appeals his judgment of divorce. Steve claims that the trial court erroneously included employee stock options as part of the marital estate. The stock options were granted during the marriage, but are not exercisable until dates occurring after the divorce. Steve argues that, as a result, the court improperly awarded his ex-wife an interest in his future endeavors. We conclude that the stock options were properly included in the marital estate. Because Steve has failed to show what, if any, portion of the options’ value is attributable to future efforts, we affirm the judgment.
Steve and Lushiang Chen were married in 1971. In 1979, Steve obtained a position with Cray Research, Inc. At the time of the divorce, Steve owned various stock options granted by Cray. The option agreements enabled Steve to purchase Cray stock at a fixed price at certain intervals, regardless of market prices. Steve had satisfied the service requirements for some of the options, but others remained non-accrued, that is, unavailable pending completion of additional service requirements. A portion of the options could not be exercised until dates occurring after the divorce. The options, which may be exercised until 1990, may not be transferred or assigned. Also, the options expire if Steve’s employment terminates for any reason other than death or disability.
The divorce judgment provided that all of the stock options, both accrued and non-accrued, were to be included in the marital estate subject to division. It allowed Steve to exercise the options if and when he desired, subject only to Cray and Security and Ex *11 change Commission regulations. Ultimately, Steve is to pay Lushiang one-half of his net profit.
Steve seeks to exclude from the marital estate those options that were granted during the marriage but are unexercisable until after the divorce. He claims that the inclusion of those options in the marital estate improperly awards Lushiang an interest in his future endeavors. We disagree.
The trial court heard expert testimony that the present value of the stock options at the date of the divorce was impossible to determine. It rejected the testimony of Steve’s expert as to present value. The weight and credibility to be accorded testimony is a trial court function. Thus, the trial court’s finding that no present value can be determined is sustained on appeal. See sec. 805.17(2), Stats.
The court considered that the options must be exercised or would expire within the next few years. It observed "[t]he fact that Mr. Chen must work another two-and-one-half to three-and-one-half years for Cray Research does not constitute such a significant factor in the value of these options that they must be excluded from or discounted in the marital estate.” The trial court considered SEC regulations, the fluctuations of the stock’s price, Cray’s sequential exercise restrictions, and tax consequences relative to the exercise of qualified or nonqualified stock options.
The trial court also considered the cost of the funds used to purchase the stock, as well as the tax rates. The trial court concluded that because no reasonably accurate present value can be assigned to the stock options, no award of a fixed sum would be practical. However, the court concluded that the stock options must be included in the marital estate.

Whether certain property is part of the marital estate subject to division presents a question of law that we decide without deference to the trial court’s decision.
Overson v. Overson,
The trial court properly included the stock options, both accrued and non-accrued, in the marital estate. Although certain stock options are not exercisable until after the time of the divorce, they are nonetheless an economic resource acquired during the marriage. Generally, these stock options are given to key employees to motivate them to remain as employees and to increase efficiency and performance.
Carey v. Rathman,
*13
Steve also contends that those options granted prior to the divorce, but after the parties separated, must be excluded from the marital estate. The marital estate is not to be limited to assets in existence at the time of the parties’ separation, but is to include assets as they exist at the time of the divorce.
See Overson,
Finally, Steve argues that the trial court improperly divided the stock options. Steve does not challenge that Lushiang is entitled to one-half of the marital estate. Rather, he contends that if the stock options are included in the marital estate we should adopt a method of division to reflect their nature as partly marital and partly separate property. He suggests a "time-rule” formula to separate out the portions of the options attributable to his post-divorce efforts. Although we approve of the use of a formula, we conclude that it is not mandatory for the trial court to use this formula in order to properly exercise its discretion in dividing the unexercised stock options.
A "time-rule” formula has been adopted in some jurisdictions.
See Salstrom v. Salstrom,
the product of a fraction whose numerator is the length of service expressed in months by respondent ... from the date of commencement of service to the date' of separation of the parties and the denominator is the length of service expressed in months from the date of commencement of service *14 to the date when an option could be first exercised, multiplied by the number of shares that could be purchased on the date of exercise.
Hug v. Hug,
While approving the use of this formula, the Hug court stressed that "the trial courts, in the exercise of their discretion, are not limited to this formula ....” Id. at 678. Rather, "the trial court should exercise its discretion to fashion an equitable allocation of separate and community interests in employee stock options_” Id. at 685.
Similarly, trial courts in Wisconsin have broad discretion in the division of the marital estate.
Selchert v. Selchert,
*15
Here, the trial court’s method of division of the stock options was an appropriate exercise of discretion. In
Bloomer v. Bloomer,
The judgment provides:
Those stock options issued to Steve Chen, including both accrued and non-accrued options, shall be distributed pursuant to the following plan:
a. Steve Chen may exercise his employee stock options at any time he wishes.
b. Upon sale of any stock purchased through these employee stock options, Steve Chen shall pay Lushiang Chen, as soon as possible, one-half of his net profit.
c. The net profit shall be computed by subtracting from the sale price of the stock the purchase price of the stock, the net after-tax interest on funds used to purchase the stock, and the net tax upon *16 the total gain, including gain occurring after the option is exercised. If the stock decreases in value after the option is exercised, one-half of Steve Chen’s allowable capital loss times his tax rate shall be added to the purchase price, (i.e., one-half of any tax savings for Steve Chen shall go to Lushiang Chen just as she in essence pays one-half the cost of exercising the option.)
d. If 18 months after the date of exercise, the stock acquired has not been sold, then Lushiang Chen may elect to be paid an amount computed using the formula set forth in Paragraph 3, using the stock price 18 months from the date of exercise, or she may choose to wait until the stock is finally sold. If she makes no election within 19 months of the date of exercise, she must wait to be paid until the stock is sold, unless the parties mutually agree on a stock transfer to settle Steve Chen’s potential liability to her.
e. At the time of any transaction involving Cray stock purchased or sold as a result of these options, Steve Chen shall provide a detailed accounting of the transaction to Lushiang Chen.
f. If there is no net profit, no additional monies are due either party. Because Lushiang Chen will have virtually no control over the exercise of the options, or the sale of the stock, she should not bear the responsibility for a loss.
The trial court’s decision does not require Steve to remain at Cray, nor even to exercise the options. Nor does the decision treat the options as any form of income in setting maintenance.
See Ondrasek v. Ondrasek,
Furthermore, Steve fails to establish that the court’s formula divides profits attributable to his future services at Cray. Under sec. 767.255, it is presumed that the marital estate, except that part that is derived through gift or inheritance, is to be divided equally. The court may alter this distribution after considering relevant factors. Section 767.255(1) to (12), Stats. Earnings and assets acquired after the divorce are not part of the marital estate subject to division.
Overson,
Steve directs us to the Executive Stock Option Agreement, dated March 19, 1984, which provides that the "company desires by granting the written Option to induce Executive to continue his employment ... and to motivate Executive to advance the interest of the Company.” Steve fails to note the preceding paragraph of the same contract, which reads: "The Executive has in the past made significant contributions to Company and has the ability by reason of training and experience to contribute to the future success of Company ....”
Thus, the observations of the
Hug
court apply: "[N]o single characterization can be given to employee stock options. Whether they can be characterized as compensation for future services, for past services, or for both, depends upon the circumstances involved in the grant of the employee stock option.”
Hug,
*18 Here, the record fails to establish that by awarding Lushiang one-half of the net profit of the stock options that were granted during the marriage, but exercised after the divorce, the trial court improperly awarded her profits due to Steve’s future services at Cray. Steve’s argument ignores the usual growth in many investments due to market forces and innumerable other variables. Because the stock options are part of the marital estate, Lushiang and Steve have a presumptively equal interest in them. There is no compelling evidence that required setting the presumption aside in this case.
Due to the numerous factors a trial court need consider in reaching an equitable result, it is not possible for us to set forth a mechanical standard to fit every case.

The first method is to divide the husband’s contributions to the plan. The second method is to attempt to calculate present value of the future benefits.
