be the same prices used above for the 1996 option. Therefore, we would multiply the eight thousand shares in the 1994 option by $19.3125, yielding a gross imputed income for 1997 of $154,000 from the 1994 option.
Performing this calculation for all of the options left unexercised in 1997, which would be the 1994, 1995, and 1996 options, and adding the results together, we arrive at a gross imputed income from the options of $421,167. A shorthand method of doing this calculation is to add together the total number of unexer-cised shares from all the options, and multiply this number by the stock price increase for the income year at issue. In this manner, the court can account for the appreciation in the value of the stock underlying the options which accrued in one year, without inadvertently considering appreciation which was gained in earlier years.
The calculated imputed appreciation from 1997, $421,167, is then added to appellant’s stipulated income for 1997, $325,743. We then arrive at appellant’s total “gross income” for purposes of child support, $746,910. This is the amount of income which the trial court would include in line fourteen on the worksheet.
We believe that the above method best captures the immediate appreciation in value the stock has gained due to appellant’s choice not to exercise the options and allow their potential value to increase. Whenever appellant chooses not to exercise his options, he is making an investment choice, and he should not be allowed to benefit from such a choice by depriving his child of the substantial growth in the stock options’ values. In addition, this method of calculating the imputed income by the anniversary date of the options eliminates the gamesmanship of the obligee choosing a high market day in an attempt to increase the child support while the obligor uses a low market day in an attempt to lessen the child support burden. Using this method, the trial court should calculate appellant’s gross income for the most recent year before the court, and recalculate appellant’s child support obligation.
The trial court’s decision to adopt a date which had no relevant relation to the case and to value appellant’s stock options according to this date was an abuse of the trial court’s discretion. Furthermore, the trial court erred by considering income from years which were not before the court.
Accordingly, appellant’s third assignment of error is sustained, and the cause must be remanded for recalculation of appellant’s child support obligation.
The trial court affirmed in part, reversed in part, and remanded for proceedings not inconsistent with this opinion.
Judgment accordingly.
