Absorption versus variable costing. Electron Inc. is a semiconductor company based in Winnipeg. In 2009, it produced a new router system for its corporate clients. The average wholesale selling price of the system is $1,200 each. For 2009, Electron estimates that it will sell 10,000 router systems and so produces 10,000 units. Actual 2009 sales are 8,960 units.

REQUIRED , 1. Calculate the operating income under variable costing.
2. Each router unit produced is allocated $165 in fixed manufacturing costs. If the production-

3. Explain the differences in operating incomes obtained in requirement 1 and requirement 2.
4. Electron’s management is considering implementing a bonus for the supervisors based on gross margin under absorption costing. What incentives will this create for the supervisors?
