Plaintiff, Colleen Pelton, appeals from a judgment of divorce entered June 2, *24 1986. Following a six-day bench trial, the trial court made findings of fact, granted an absolute judgment of divorce, ordered the distribution of property, and awarded alimony to plaintiff. Defendant, James Pelton, cross-appeals.
The parties were married on April 16, 1955. At the time of the marriage, plaintiff was twenty-three years of age, while defendant was thirty years of age. Three children were born during the marriage, all of whom reached the age of majority prior to the divorce action. At the time of trial, plaintiff was age fifty-three and defendant age sixty-one.
The parties entered into a separation agreement in 1976, which provided for a $160 per week payment to plaintiff with defendant also making the mortgage and utility payments and providing for plaintiff's hospitalization insurance and automobile.
Plaintiff did not graduate from high school and, since the marriage, did very little work outside of the home. She became depressed and began drinking alcohol excessively after the birth of their youngest child. She admitted to frequenting bars in the afternoon and not returning home on occasion for days at a time.
Defendant worked long hours in his business and promptly paid for plaintiff's expenses during their separation. He had no dispute with paying alimony as part of the judgment of divorce.
In deciding the case, the trial court awarded assets valued at approximately $317,000 to plaintiff and assets valued at approximately $664,000 to defendant. The court acknowledged that defendant received more than twice as much as plaintiff, but indicated that plaintiff had engaged in a long continued course of conduct that led to the breakdown in the marriage and would not be rewarded *25 for that conduct. The trial court also indicated that the parties were separated for the last ten years of this marriage and that plaintiff's contribution to the marital estate had thereafter been minimal.
Because defendant's 1984 W-2 federal tax form indicated an income of approximately $80,000, the trial court awarded alimony in the amount of $2,000 per month or $24,000 per year. In addition, defendant was required to maintain hospitalization coverage for the benefit of plaintiff.
The first issue we consider on appeal is whether the trial court's valuation of marital assets, and in particular the valuation of defendant's stock in two corporations, was erroneous. Defendant owned a fifty-percent interest in two closely held corporations. Each party presented expert testimony as to the value of these business interests. An unaccepted offer to purchase the businesses by the co-owner of these corporations was also considered in arriving at the valuation of $375,000 for defendant's stock. A trial court's valuation of an asset is a finding of fact that this Court will reverse only if found to be clearly erroneous. Kowalesky v Kowalesky, 148 Mich App 151; 384 NW2d 112 (1986), lv den 425 Mich 876 (1986). A finding is "clearly erroneous" if, after a review of the entire record, the reviewing court is left with the definite and firm conviction that a mistake has been committed. Tuttle v Dep't of State Highways, 397 Mich 44; 243 NW2d 244 (1976).
The valuation of stock in a closely held corporation is often a difficult task. The trial court may, but is not required to, accept either parties' valuation evidence. Here, the trial court rejected both expert opinions and arrived at a figure which provided a higher valuation than that outlined in a buy-sell agreement and that of defendant's expert, *26 but significantly lower than the valuation of plaintiff's expert. A review of other cases where marital assets were valued between divergent estimates given by expert witnesses indicates that the trial court has great latitude in arriving at a final figure. Mitchell v Mitchell, 333 Mich 441; 53 NW2d 325 (1952); Greenough v Greenough, 354 Mich 508; 93 NW2d 391 (1958); Schaffer v Schaffer, 37 Mich App 711; 195 NW2d 326 (1972). The trial court had the best opportunity to view the demeanor of the witnesses and weigh their credibility. There was no error in its valuation of marital assets.
The next question to consider is whether there was an abuse of discretion in the division of the assets. An equal division of property is not required, and no mathematical formula governs the division. Christofferson v Christofferson, 363 Mich 421; 109 NW2d 848 (1961). Rather than mathematical precision, the goal is to fashion a fair and equitable division of property in light of all of the circumstances. Greaves v Greaves, 148 Mich App 643; 384 NW2d 830 (1986); Bone v Bone, 148 Mich App 834; 385 NW2d 706 (1986). In Vance v Vance, 159 Mich App 381; 406 NW2d 497 (1987), this Court reviewed several factors a trial court must examine when dividing marital property: the duration of the marriage, the parties' contributions to the marital estate, the parties' station in life and earning abilities, fault or past conduct, and other equitable circumstances which may exist. Although the property division in this case was not equal, it was equitable, especially in light of the alimony award.
Next, plaintiff claims that the alimony award was an abuse of discretion in that there was no definite period of duration for these payments. In addition to the rather standard provisions for *27 termination of alimony upon either party's death or remarriage, there is a proviso in the divorce judgment that the alimony award is subject to the "further order of this Court based on change in circumstances of either of the parties." Plaintiff fears that defendant may manipulate his earnings in an attempt to avoid payments. Defendant cross-appeals from the alimony provision, claiming that the award of $2,000 per month is excessive in light of his age and business prospects.
An award of alimony is within the trial court's discretion. Hatcher v Hatcher, 129 Mich App 753; 343 NW2d 498 (1983). This Court reviews an alimony order de novo, but will not modify an award unless convinced that, had it been in the position of the trial court, it would have reached a different result. Parrish v Parrish, 138 Mich App 546; 361 NW2d 366 (1984).
The order in this case allows flexibility in determining the possibility of changed circumstances. The trial court is in the best position to consider if, and what, modification in the alimony order may be necessary in the future. While defendant's control of his income is greater than that of others who may be employed by larger corporations, the burden of proving a change of circumstances is on the party seeking a modification. In addition, there is the possibility that plaintiff may seek an increase should the facts warrant such action hereafter. In McCallister v McCallister, 101 Mich App 543; 300 NW2d 629 (1980), this Court held that an alimony award without any mechanism for modification due to a change of circumstances constituted an abuse of discretion. Under the facts of this case, there was no abuse of discretion.
The last matter to decide is whether the alimony award is excessive and should be reduced. The factors to consider in determining this question *28 are set out in Hatcher, supra. Here, the parties' ages, income and assets are such that $2,000 per month is not excessive. This will allow each party to maintain their standard of living and is fair and equitable. Alimony should be paid to plaintiff on a regular basis and should not be subject to defendant's claim of hardship in that bonuses are paid to him when "appropriate and possible." Defendant's annual income is sufficient to pay this alimony amount on a monthly basis, and he shall have to set his financial priorities with this in mind. The stay of execution of the alimony order by the trial court is set aside.
Affirmed.
