On January 1, 2017, Magee Corporation stared doing business by hiring R. Walker as an employee at an annual salary of $50,000, with an annual salary increment of $10,000. Based on his current age and the companys retirement program, Walker is required to retire at the end of the year in 2020. However, at his option, he could retire any time after completing one full year of service. Regardless of when he retires, the company will pay a lump-sum pension at the end of 2021. The lump-sum payment is calculated to be 25% of the cumulative lifetime salary Walker earned. Magees annual discount rate is 10%. Assume that Walker retires at the end of 2020.

Required

1. Assuming that Magee Corporation does not fund its pension expense, calculate this expense for 2017-2020. Clearly identify the service and interest cost components. Based on your calculations, provide journal entries to record the effects of pensions during 20172021.
2. Assume that Magee fully funds its pension cost as soon as it vests and that the contributions to the pension fund earn exactly a 10% rate of return annually. Based on these revised assumptions, redo requirement 1.
3. Explain why the total pension expense in requirement 1 and in requirement 2 differ.
4. Assume that Magee does not fund its pension expense. Discuss how different assumptions regarding the discount rate affect the pension expense. Compare the pension expense with discount rates of 5%, 10%, and 15%.
