Gerrie added the DC to DB rollover option into an employer plan at the request of several members of a professional services firm of about 400 employees.
To make this move, you have to work for a company that offers both a 401(k) defined contribution plan and a traditional defined benefit pension plan, and offers the option to roll assets from the former (the DC plan) to the latter (the DB pension).
Christine Mahoney of Mercer Consulting reckons that the cost of funding a 60-year-old employee in a DB scheme is 12% of payroll, whereas in a DC plan it is just 6%.
