Please Explain this Case study question. Thank you!

Kevin: This year, we implemented management bonus plan for the semi-conductor division, where the supervisors are rewarded based on gross margin under absorption costing. Ever since we announced this bonus plan, we noted an abnormal amount of build-up in our semi-conductor chip inventory. Can you determine what our operating income would be between absorption costing and variable costing? Is there a reason why there is an inventory build-up? How can this be rectified? I have provided you the information in Appendix III. Appendix III Financial Information - Semi-conductor division CPA, the relevant costing information that you need to perform your analysis is noted below for the semi-conductor chips. Feel free to refer to Appendix I for actual sales and budgeted sales information for the semi-conductor chips. Tek Tower Inc.
