Your company currently offers a defined benefit plan using the following formula for retirement benefits at age 65: final average pay, years of service, and a 2 percent replacement income factor. There is a 2 percent actuarial reduction per year for retirement between the ages of 55 (the earliest date on which one can retire) and 65. There is no actuarial cost for the mandatory 50 percent spouse option arising from age variations between the spouses. Your CFO considers the plan too costly. You decide to keep the DBP as is for your current employees, but offer a modified DBP for new hires. The new hire plan will continue to encourage long and productive service, but will reduce the cost to the company. Briefly identify and describe three appropriate design changes you would make for the new hire plan that would best generate these results.
